The crimp connector has a connection zone for connecting to the electrical conductor and a crimp clamp which, when the connection is made, encloses the electrical conductor and crimps it tightly both within itself and to the connection zone of the crimp connector. This means that the crimp clamp, by crimping, i.e., by plastically deforming the crimp clamp, clamps the electrical conductor within itself and thereby mechanically and electrically secures the electrical conductor to the connection zone of the crimp connector. The crimp clamp can, for example, be ring-shaped or have one or two tabs, tongues, or the like, which are bent into the crimp clamp by plastic deformation.

Erfindungsgemäß weist der Quetschverbinder eine rinnenförmige Vertiefung in der Verbindungszone auf, in der der elektrische Leiter zum Verbinden angeordnet und mit der Quetschklemme festgeklemmt wird.According to the invention, the crimp connector has a groove-shaped recess in the connection zone in which the electrical conductor is arranged for connection and clamped with the crimp clamp.

Die rinnenförmigen Vertiefung verbessert einen mechanischen Halt des elektrischen Leiters am Quetschverbinder und verringert insbesondere einen elektrischen Übergangswiderstand zwischen dem Quetschverbinder und dem elektrischen Leiter durch eine Anformung des elektrischen Leiters an die Vertiefung in der Verbindungszone des Quetschverbinders beim Festquetschen des elektrischen Leiters mit der Quetschklemme, wodurch die elektrisch leitende Verbindung zwischen dem Quetschverbinder und dem elektrischen Leiter verbessert ist.The groove-shaped recess improves the mechanical hold of the electrical conductor on the crimp connector and, in particular, reduces electrical contact resistance between the crimp connector and the electrical conductor by molding the electrical conductor to the recess in the connection zone of the crimp connector when the electrical conductor is crimped with the crimp clamp, thereby improving the electrically conductive connection between the crimp connector and the electrical conductor.

Die rinnenförmige Vertiefung kann beispielsweise einen eckigen, beispielsweise rechteckigen oder trapezförmigen, oder einen gerundeten, beispielsweise kreisförmigen oder ellipsenförmigen Querschnitt aufweisen. Eine bevorzugte Ausgestaltung der Erfindung sieht eine treppenstufenförmige Vertiefung mit in einer Längsrichtung der Vertiefung verlaufenden Stufen vor. Ein treppenstufenförmiger Querschnitt der Vertiefung hat sich als vorteilhaft hinsichtlich eines niedrigen elektrischen Übergangswiderstands zwischen dem Quetschverbinder und dem elektrischen Leiter gezeigt.The channel-shaped recess can, for example, have an angular, such as rectangular or trapezoidal, or a rounded, such as circular or elliptical, cross-section. A preferred embodiment of the invention provides a step-shaped recess with steps extending in a longitudinal direction. A step-shaped cross-section of the recess has proven advantageous with regard to a low electrical contact resistance between the crimp connector and the electrical conductor.

Die Erfindung sieht vor, dass der Quetschverbinder jedenfalls in der Verbindungszone gestapelte beziehungsweise geschichtete, das heißt aufeinander angeordnete Bleche aufweist. Dabei überbrückt eines der geschichteten Bleche, das hier auch als Grundblech bezeichnet wird, die Vertiefung an einem Grund. Das Grundblech bildet sozusagen einen Grund der Vertiefung. Geschichtet auf einer Seite des Grundblechs angeordnete Bleche weisen Aussparungen auf, die die Vertiefung seitlich begrenzen. Zur Ausbildung der Treppenstufenform der Vertiefung sind die Aussparungen bei Blechen, die näher am Grundblech angeordnet sind, schmaler sind als bei Blechen, die weiter weg vom Grundblech angeordnet sind derart, dass die Vertiefung mit zunehmendem Abstand von dem Grundblech stufenförmig breiter wird. Grundsätzlich genügt ein Blech mit einer Aussparung auf einer Seite des Grundblechs, wodurch eine einstufige Vertiefung gebildet ist. Vorzugsweise sind mehrere geschichtete Bleche mit unterschiedlich breiten Aussparungen auf der einen Seite des Grundblechs angeordnet, wobei zur Ausbildung einer Stufe mehrere Bleche gleich breite Aussparungen aufweisen können. Auch können mehrere Bleche ohne Aussparung als Grundbleche vorhanden sein.The invention provides that the crimp connector has stacked or layered, i.e., superimposed, sheets in the connection zone. One of the layered sheets, also referred to here as the base sheet, bridges the recess at one end. The base sheet, so to speak, forms the base of the recess. Layered sheets arranged on one side of the base sheet have recesses that laterally define the recess. To create the stepped shape of the recess, the recesses are narrower in sheets located closer to the base sheet than in sheets located further away, such that the recess widens in a stepped manner with increasing distance from the base sheet. In principle, one sheet with a recess on one side of the base sheet is sufficient, thus forming a single-step recess. Preferably, several layered sheets with recesses of varying widths are arranged on one side of the base sheet, whereby several sheets can have recesses of the same width to form a step. Alternatively, several sheets without recesses can be used as base sheets.

Die Quetschklemme bevorzugter Ausführungsformen der Erfindung ist ein von dem Quetschverbinder separates Bauteil, das die Verbindungszone des Quetschverbinders und bei hergestellter Verbindung den elektrischen Leiter umschließt. Die Quetschklemme lässt sich dadurch aus einem anderen Werkstoff, beispielsweise auch als nicht geschichtetes Blech und/oder mit einer anderen Dicke als die geschichteten Bleche in der Verbindungszone des Quetschverbinders herstellen. Die Ausführung der Quetschklemme als separates Bauteil ermöglicht eine Anpassung an ihre Funktion ohne Beschränkungen durch die Ausgestaltung der Verbindungszone.The crimp clamp of preferred embodiments of the invention is a component separate from the crimp connector, which encloses the connection zone of the crimp connector and, when the connection is made, the electrical conductor. The crimp clamp can thus be manufactured from a different material, for example, as unlaminated sheet metal and/or with a different thickness than the laminated sheets in the connection zone of the crimp connector. Designing the crimp clamp as a separate component allows for adaptation. to their function without restrictions due to the design of the connection zone.

Eine Weiterbildung sieht vor, dass die Quetschklemme die geschichteten Bleche, in ihrer geschichteten und vorgesehenen Lage zueinander hält, in der die Aussparungen der geschichteten Bleche die Vertiefung in der Verbindungszone des Quetschverbinders bilden. Bei hergestellter Quetschverbindung spannt die Quetschklemme die geschichteten Bleche zusammen und gegen den elektrischen Leiter.A further development stipulates that the crimp clamp holds the layered sheets in their intended and stacked position relative to each other, with the recesses in the layered sheets forming the depression in the connection zone of the crimp connector. Once the crimp connection is established, the crimp clamp clamps the layered sheets together and against the electrical conductor.

Beispielsweise weisen die geschichteten Bleche Durchbrüche auf, durch die die Quetschklemme durchgeht, wobei die Quetschklemme die Durchbrüche der Bleche deckungsgleich aufeinander und dadurch die geschichteten Bleche in ihrer vorgesehenen Lage hält. Vorzugsweise sind die Durchbrüche in den geschichteten Blechen beiderseits der Vertiefung vorgesehen, damit die durch die Durchbrüche durchgehende Quetschklemme die geschichteten Bleche besser verdrehsicher gegeneinander aneinander hält.For example, the layered sheets have openings through which the crimp clamp passes, the crimp clamp aligning the openings in the sheets and thereby holding the layered sheets in their intended position. Preferably, the openings in the layered sheets are provided on both sides of the recess so that the crimp clamp passing through the openings holds the layered sheets more securely against rotation.

In einer bevorzugten Ausgestaltung der Erfindung weist die Quetschklemme einen insbesondere U-förmigen Bügel auf, der den elektrischen Leiter auf einer Seite des Anschlusskontakts ohne Unterbrechung umschließt und festklemmt. Die Quetschklemme ist beiderseits des elektrischen Leiters am Anschlusskontakt festgelegt und umschließt den elektrischen Leiter ohne Unterbrechung von einer Seite zu einer gegenüberliegenden Seite des elektrischen Leiters. Die Quetschklemme klemmt den elektrischen Leiter zwischen sich und dem Anschlusskontakt fest und spannt den elektrischen Leiter in die Vertiefung im Anschlusskontakt. Dadurch dass die Quetschklemme bei dieser Ausführung der Erfindung den elektrischen Leiter ohne Unterbrechung umschließt, kann sie sich nicht durch Aufbiegen lockern, wodurch die Klemmung des elektrischen Leiters in der Quetschklemme und am Anschlusskontakt des erfindungsgemäßen Quetschverbinders verbessert ist.In a preferred embodiment of the invention, the crimp terminal has a U-shaped clamp that completely encloses and clamps the electrical conductor on one side of the terminal contact. The crimp terminal is fixed to the terminal contact on both sides of the electrical conductor and completely encloses the conductor from one side to the opposite side. The crimp terminal clamps the conductor between itself and the terminal contact and secures it in the recess in the terminal contact. Because the crimp terminal completely encloses the conductor in this embodiment, it cannot loosen by bending, thus improving the clamping of the conductor in the crimp terminal and at the terminal contact of the crimp connector according to the invention.

Eine Weiterbildung der Erfindung sieht vor, dass die Quetschklemme einen in den elektrischen Leiter eingeformten Vorsprung an ihrer dem elektrischen Leiter zugewandten Innenseite aufweist. Der Vorsprung der Quetschklemme formt eine Vertiefung in den elektrischen Leiter und steht von der Innenseite der Quetschklemme in die Vertiefung des elektrischen Leiters ab. Dadurch wird ein Formschluss zwischen der Quetschklemme und dem elektrischen Leiter bewirkt, der den elektrischen Leiter gegen ein Herausziehen aus der Quetschklemme hält. Dieser halt durch Formschluss wirkt zusätzlich zu einem Halt des elektrischen Leiters in der Quetschklemme durch deren Klemmkraft, wodurch der mechanische Halt des elektrischen Leiters in der Quetschklemme und in der Vertiefung im Anschlusskontakts des erfindungsgemäßen Quetschverbinders verbessert ist.A further development of the invention provides that the crimp terminal has a projection formed into the electrical conductor on its inner side facing the conductor. This projection forms a recess in the conductor and extends from the inner side of the crimp terminal into this recess. This creates a positive fit between the crimp terminal and the conductor, preventing the conductor from being pulled out of the terminal. This positive fit, in addition to the clamping force of the terminal, provides additional retention of the conductor, thus improving the mechanical retention of the conductor both within the terminal and in the recess of the terminal contact of the crimp connector according to the invention.

Die erfindungsgemäße Quetschverbindung mit den Merkmalen des Anspruchs 9 weist einen elektrischen Anschlusskontakt mit einem Quetschverbinder der vorstehend erläuterten Art und einen elektrischen Leiter auf, der in der Vertiefung in der Verbindungszone des Quetschverbinders angeordnet, von der Quetschklemme umschlossen und mit der Quetschklemme in der Quetschklemme und in der Vertiefung in der Verbindungszone des Quetschverbinders festgequetscht, das heißt durch eine plastische Verformung der Quetschklemme mechanisch festgelegt und elektrisch leitend mit dem Quetschverbinder und über den Quetschverbinder elektrisch leitend mit dem Anschlusskontakt verbunden ist.The crimp connection according to the invention with the features of claim 9 has an electrical connection contact with a crimp connector of the type described above and an electrical conductor which is arranged in the recess in the connection zone of the crimp connector, enclosed by the crimp clamp and crimped firmly with the crimp clamp in the crimp clamp and in the recess in the connection zone of the crimp connector, i.e. mechanically fixed by a plastic deformation of the crimp clamp and electrically connected to the crimp connector and via the crimp connector electrically connected to the connection contact.

Der Anschlusskontakt weist beispielsweise einen elektrischen Steckverbinder, beispielsweise einen Stecker oder eine Kupplung als Gegenstück für einen Stecker, einen elektrischen Schraubverbinder oder eine Öse zur Herstellung einer elektrisch leitenden Schraubverbindung auf. Die Aufzählung ist beispielhaft und nicht abschließend. Der Anschlusskontakt des Quetschverbinders ist zu einer elektrisch leitenden Verbindung des elektrischen Leiters mit beispielsweise einer Stromquelle oder einem anderen elektrischen Leiter vorgesehen.The connection contact features, for example, an electrical connector, such as a plug or socket as a counterpart to a plug, an electrical screw connector, or an eyelet for creating an electrically conductive screw connection. This list is not exhaustive. The connection contact of the crimp connector is designed for an electrically conductive connection of the electrical conductor to, for example, a power source or another electrical conductor.

Der elektrische Leiter weist beispielsweise ein Kabel und insbesondere eine Litze auf.The electrical conductor includes, for example, a cable and, in particular, a strand.

Der in der Zeichnung dargestellte, erfindungsgemäße Quetschverbinder 1 weist einen elektrischen Anschlusskontakt 2 auf und ist zu einem mechanischen und elektrisch leitenden Verbinden mit einem elektrischen Leiter 3 vorgesehen. Der elektrische Anschlusskontakt 2 ist im Ausführungsbeispiel als Steckerkupplung mit einem Steckloch 4 zum Einstecken eines beziehungsweise zum Aufstecken auf einen nicht dargestellten, beispielsweise zylindrischen Gegenkontakt ausgebildet.The crimp connector 1 according to the invention, as shown in the drawing, has an electrical connection contact 2 and is designed for mechanical and electrically conductive connection with an electrical conductor 3. In the exemplary embodiment, the electrical connection contact 2 is designed as a plug socket with a socket 4 for inserting or for mounting onto a mating contact (not shown), for example, a cylindrical one.

Im Steckloch 4 weist der Anschlusskontakt 2 einen Stapel gleichachsig gestapelt aufeinander angeordneter Kontaktbügelfedern 5 auf. Im Ausführungsbeispiel sind die Kontaktbügelfedern 5 kreisförmig und an einer Umfangsstelle offen. Sie weisen an einander gegenüberliegenden Umfangsstellen - im Ausführungsbeispiel insgesamt vier - nach außen abstehende äußere Vorsprünge 15 auf, die innen an dem Steckloch 4 des Anschlusskontakt 2 anliegen. Innen weisen die Kontaktbügelfedern 5 - im Ausführungsbeispiel zwei - innere Vorsprünge 16 aneinander gegenüberliegenden Umfangsstellen auf, die nach innen abstehen und mit einer radialen Vorspannung an dem nicht dargestellten, beispielsweise zylindrischen Gegenkontakt anliegen, wenn der Gegenkontakt in das Steckloch 4 beziehungsweise in die Kontaktbügelfedern 5 in dem Steckloch 4 des Anschlusskontakt 2 gesteckt ist. Im Ausführungsbeispiel sind die Kontaktbügelfedern 5 Blechstanzteile, wobei andere Ausführungen erfindungsgemäß möglich sind. In Figur 1 ist eine Kontaktbügelfeder 5 über einem Deckblech 17 des Anschlusskontakts 2 des erfindungsgemäßen Quetschverbinders 1 gezeichnet, um die Form der Kontaktbügelfedern 5 zu zeigen.In the socket 4, the connecting contact 2 has a stack of coaxially stacked contact springs 5. In the exemplary embodiment, the contact springs 5 are circular and open at one circumferential point. They have outwardly projecting outer projections 15 at opposite circumferential points – in the exemplary embodiment a total of four – which are connected to the inside of the The contact springs 5 are located in the socket 4 of the connecting contact 2. Inside, the contact springs 5 – in the exemplary embodiment, two – have internal projections 16 on opposing circumferential points, which project inwards and bear against the mating contact (not shown), for example, a cylindrical one, with a radial preload when the mating contact is inserted into the socket 4 or into the contact springs 5 in the socket 4 of the connecting contact 2. In the exemplary embodiment, the contact springs 5 are stamped sheet metal parts, although other embodiments are possible according to the invention. Figure 1 A contact spring 5 is shown above a cover plate 17 of the connecting contact 2 of the crimp connector 1 according to the invention, in order to show the shape of the contact springs 5.

Durch die radiale Vorspannung, mit der die Kontaktbügelfedern 5 an dem nicht dargestellten Gegenkontakt anliegen, wenn der Gegenkontakt in das Steckloch 4 beziehungsweise in die Kontaktbügelfedern 5 des Anschlusskontakts 2 des erfindungsgemäßen Quetschverbinders 1 gesteckt ist, weist der Quetschverbinder 1 eine gute elektrische Kontaktierung mit einem niedrigen elektrischen Übergangswiderstand zwischen dem Anschlusskontakt 2 des Quetschverbinders 1 und dem eingesteckten, nicht dargestellten Gegenkontakt auf.Due to the radial preload with which the contact springs 5 bear against the mating contact (not shown) when the mating contact is inserted into the socket 4 or into the contact springs 5 of the terminal contact 2 of the crimp connector 1 according to the invention, the crimp connector 1 has good electrical contact with a low electrical contact resistance between the terminal contact 2 of the crimp connector 1 and the inserted mating contact (not shown).

Um die gestapelt in dem Steckloch 4 des Anschlusskontakt 2 des erfindungsgemä-ßen Quetschverbinders 1 angeordneten Kontaktbügelfedern 5 axial in dem Steckloch 4 zu halten, sind die Deckbleche 17 oben und unten auf dem Kontaktbereich 7 angeordnet, die ein zu dem Steckloch 4 konzentrisches Loch aufweisen, dass die Kontaktbügelfedern 5 überdeckt und dadurch axial in dem Steckloch 4 hält. Ein Durchmesser des Lochs in den Deckblechen 17 ist mindestens so groß wie ein Innendurchmesser der Kontaktbügelfedern 5 derart, dass die inneren Vorsprünge 16 der Kontaktbügelfedern 5 nach innen über das Loch in den Deckblechen 17 überstehen. In Figur 2 ist ein oberes der beiden Deckbleche 17 nicht gezeichnet, damit die in dem Steckloch 4 des Anschlusskontakt 2 gestapelt angeordneten Kontaktbügelfedern 5 sichtbar sind.To hold the stacked contact springs 5 axially in the socket 4 of the connecting contact 2 of the crimp connector 1 according to the invention, cover plates 17 are arranged above and below on the contact area 7. These cover plates have a hole concentric with the socket 4 that covers the contact springs 5 and thereby holds them axially in the socket 4. The diameter of the hole in the cover plates 17 is at least as large as the inner diameter of the contact springs 5 such that the inner projections 16 of the contact springs 5 protrude inwards beyond the hole in the cover plates 17. Figure 2 One of the two cover plates 17 is not shown so that the contact springs 5 stacked in the socket 4 of the connection contact 2 are visible.

Erfindungsgemäß weist der Quetschverbinder 1 gestanzte, lasergeschnittene oder in anderer Weise hergestellte Bleche 6 auf, die geschichtet deckungsgleich aufeinander liegend beziehungsweise aneinander anliegend angeordnet sind. Aufgrund ihrer geschichteten Anordnung aneinander beziehungsweise aufeinander können die Bleche 6 auch als gestapelt oder als stanzpaketiert aufgefasst werden.According to the invention, the crimp connector 1 comprises stamped, laser-cut, or otherwise manufactured sheet metal sheets 6, which are arranged in a layered, congruent arrangement, either lying on top of or abutting each other. Due to their layered arrangement, the sheet metal sheets 6 can also be considered stacked or as stamped packages.

Jedes der Bleche 6 weist einen Kontaktbereich 7 mit dem Steckloch 4 und eine Verbindungszone 8 auf. Die Kontaktbereiche 7 der geschichteten Bleche 6 bilden den Anschlusskontakt 2 des erfindungsgemäßen Quetschverbinders 1.Each of the metal sheets 6 has a contact area 7 with the insertion hole 4 and a connection zone 8. The contact areas 7 of the stacked metal sheets 6 form the connection contact 2 of the crimp connector 1 according to the invention.

In der Verbindungszone 8 weisen die Bleche 6 mit Ausnahme von einem oder mehreren Grundblechen 9 eine - im Ausführungsbeispiel rechteckige - Aussparung 10 auf, die sich übereinander befinden und eine rinnenförmige Vertiefung 11 bilden, wenn die Bleche 6 deckungsgleich geschichtet aufeinander beziehungsweise aneinander angeordnet sind. Wie geschrieben weisen ein oder mehrere der Bleche 6 - im Ausführungsbeispiel sind es willkürlich zwei der Bleche 6 - keine Aussparung 10 auf, sondern überbrücken die Aussparungen 10 in den Verbindungszonen 8 der anderen Bleche 6. Die hier auch als Grundblech/e 9 bezeichneten Bleche 6 ohne Aussparung 10 befinden sich auf einer Seite der geschichteten Bleche 6, das heißt die Bleche 6 mit den Aussparungen 10 sind geschichtet auf einer Seite des oder der Bleche 6 ohne Aussparung 10, das heißt auf einer Seite der Grundbleche 9 angeordnet derart, dass das oder die Grundblech/e 9 die von den Aussparungen 10 der anderen Bleche 6 gebildete Vertiefung 11 an einem Grund der Vertiefung 11 begrenzen, das heißt das oder die Grundblech/e 9 bilden den Grund der Vertiefung 11, die die Aussparungen 10 in den anderen Blechen 6 in der Verbindungszone 8 der erfindungsgemäßen Quetschverbinders 1 bilden.In the connection zone 8, the sheets 6, with the exception of one or more base sheets 9, have a recess 10 – rectangular in the exemplary embodiment – which are located one above the other and form a channel-shaped depression 11 when the sheets 6 are stacked on top of or next to each other in a congruent manner. As written, one or more of the sheets 6 – in the exemplary embodiment, arbitrarily two of the sheets 6 – do not have a recess 10, but bridge the recesses 10 in the connection zones 8 of the other sheets 6. The sheets 6 without recess 10, also referred to here as base sheet(s) 9, are located on one side of the stacked sheets 6, that is, the sheets 6 with the recesses 10 are stacked on one side of the sheet(s) 6 without recess 10, i.e., arranged on one side of the base sheets 9, such that the base sheet(s) 9 limit the recess 11 formed by the recesses 10 of the other sheets 6 at a base of the recess 11, that is, the base sheet(s) 9 form the base of the recess 11 formed by the recesses 10 in the other sheets 6 in the connection zone 8 of the crimp connector 1 according to the invention.

Die Aussparungen 10 in den Blechen 6 weisen verschiedene Breiten auf, und zwar sind die Aussparungen 10 in den Blechen 6, die dem oder den Grundblech/en 9 näher sind, schmaler als die Aussparungen 10 in Blechen 6, die dem oder den Grundblech/en 6 ferner sind. Mit zunehmendem Abstand von dem oder den Grundblech/en 9 werden die Aussparungen 10 in den Blechen 6 also breiter. Dadurch ist die Vertiefung 11 in der Verbindungszone 8 des erfindungsgemäßen Quetschverbinders 1 treppenstufenförmig, sie weist einen an beiden Seiten treppenstufenförmigen Querschnitt beziehungsweise treppenstufenförmige Längsseiten beziehungsweise Wangen auf. Zur Ausbildung der Stufen an beiden Seiten der Vertiefung 11 können auch jeweils zwei oder mehr Bleche 6 gleich breite Aussparungen 10 aufweisen und dadurch gemeinsam jeweils eine Stufe bilden. Im Ausführungsbeispiel sind die Aussparungen 10 aller Bleche 6 verschieden breit.The recesses 10 in the sheets 6 have different widths; those recesses 10 in the sheets 6 that are closer to the base sheet(s) 9 are narrower than those recesses 10 in the sheets 6 that are farther away from the base sheet(s) 6. Thus, the recesses 10 in the sheets 6 become wider with increasing distance from the base sheet(s) 9. This means that The recess 11 in the connection zone 8 of the crimp connector 1 according to the invention is step-shaped, having a step-shaped cross-section or longitudinal sides or cheeks on both sides. To form the steps on both sides of the recess 11, two or more sheets 6 can each have recesses 10 of the same width and thus together form a step. In the exemplary embodiment, the recesses 10 of all sheets 6 are of different widths.

Eine Zunahme der mit zunehmendem Abstand von dem oder den Grundblech/en 9 zunehmende Breite der Aussparungen 10 in den Blechen 6 des erfindungsgemä-ßen Quetschverbinders 1 wird mit zunehmendem Abstand von dem oder den Grundblech/en 9 kleiner, das heißt eine Stufenbreite der Stufen quer zu der Vertiefung 11 (eine Tiefe der "Trittstufe) wird mit zunehmendem Abstand von dem oder den Grundblech/en 9 kleiner, was in Figur 2 erkennbar ist. Eine gedachte, gekrümmte Linie des Querschnitts der Vertiefung 11 an den Seiten der Vertiefung 11 durch Kanten der Stufen sind dadurch keine schräg zum Grund der Vertiefung 11 ansteigenden Geraden, sondern verlaufen bogenförmig. Der Querschnitt der stufenförmigen Vertiefung 11 ist dadurch an einen elektrischen Leiter 3 mit rundem, nicht unbedingt kreisförmigem Querschnitt angepasst.The width of the recesses 10 in the plates 6 of the crimp connector 1 according to the invention decreases with increasing distance from the base plate(s) 9, i.e., the step width of the steps transverse to the recess 11 (the depth of the "step") decreases with increasing distance from the base plate(s) 9, which in Figure 2 This is evident. An imaginary, curved line of the cross-section of the depression 11 along the sides of the depression 11, formed by the edges of the steps, is therefore not a straight line rising obliquely towards the bottom of the depression 11, but rather follows an arc. The cross-section of the stepped depression 11 is thus adapted to an electrical conductor 3 with a round, but not necessarily circular, cross-section.

Die Vertiefung 11 weist vorzugsweise einen treppenstufenförmigen Querschnitt auf, Vertiefungen mit anderen Querschnitten, beispielsweise eckigem, rechtwinkligem oder trapezförmigem Querschnitt oder mit kreisförmig oder nicht kreisförmig gerundetem Querschnitt sind allerdings ebenfalls möglich (nicht dargestellt).The recess 11 preferably has a step-shaped cross-section; however, recesses with other cross-sections, for example square, rectangular or trapezoidal cross-sections or with circular or non-circular rounded cross-sections, are also possible (not shown).

Im Ausführungsbeispiel weist der erfindungsgemäße Quetschverbinder 1 zwei Grundbleche 9 und sechs Bleche 6 mit verschieden breiten Aussparungen 10 auf, die aneinander beziehungsweise aufeinander geschichtet auf einer Seite der beiden Grundblechen 9 angeordnet sind, wobei Bleche 6 mit schmalerer Aussparung 10 näher an dem oder den Grundblech/en 9 und Bleche 6 mit breiterer Aussparung 10 weiter entfernt von dem oder den Grundblech/en 9 angeordnet sind.In the exemplary embodiment, the crimp connector 1 according to the invention has two base plates 9 and six plates 6 with recesses 10 of different widths, which are arranged stacked on top of each other on one side of the two base plates 9, wherein plates 6 with a narrower recess 10 are arranged closer to the base plate(s) 9 and plates 6 with a wider recess 10 are arranged further away from the base plate(s) 9.

Die beiden Deckbleche 17 sind im Kontaktbereich 7 koaxial zu dem Steckloch 4 oben und unten an den gestapelten Blechen 6 angeordnet. Im Ausführungsbeispiel werden die beiden Deckbleche 17 und die Bleche 6, 9 mit vier Nieten zusammengehalten, die um das Steckloch 4 herum angeordnet sind. Die Bleche 6, 9, 17 können auch in anderer Weise zusammengehalten werden.The two cover plates 17 are arranged coaxially to the mounting hole 4 at the top and bottom of the stacked plates 6 in the contact area 7. In the exemplary embodiment, the two cover plates 17 and the plates 6, 9 are held together by four rivets arranged around the mounting hole 4. The plates 6, 9, 17 can also be held together in another way.

Der erfindungsgemäße Quetschverbinder 1 weist eine Quetschklemme 12 auf, die einstückig mit dem Quetschverbinder 1 sein kann, im Ausführungsbeispiel jedoch ein vom Quetschverbinder 1 beziehungsweise von seinen Blechen 6, 9 separates Bauteil ist. Die Quetschklemme 12 ist in der Verbindungszone 8 des Anschlusskontakt 2 beziehungsweise der gestapelten Bleche 6, 9 angeordnet, die den Anschlusskontakt 2 bilden. Im Ausführungsbeispiel besteht die Quetschklemme 12 aus einem Blechstreifen, der zunächst zu einem U-förmigen Bügel gebogen ist (siehe Figur 1). Schenkel des U-förmigen, die Quetschklemme 12 bildenden Bügels sind beziehungsweise werden durch Durchbrüche 13 in den geschichteten Blechen 6, 9 des Quetschverbinders 1 gesteckt. Im Ausführungsbeispiel sind die Durchbrüche 13 als Schlitze beiderseits der Aussparungen 10 in den Blechen 6, 9 ausgeführt, die die Vertiefung 11 in der Verbindungszone 8 des Quetschverbinders 1 bilden. Die durch die Durchbrüche 13 der Bleche 6, 9 gesteckte Quetschklemme 12 und die Nieten halten die geschichteten Bleche 6, 9 in ihrer deckungsgleich aufeinander beziehungsweise aneinander geschichteten beziehungsweise gestapelten Lage zueinander.The crimp connector 1 according to the invention has a crimp clamp 12, which can be integral with the crimp connector 1, but in the exemplary embodiment is a component separate from the crimp connector 1 or from its plates 6, 9. The crimp clamp 12 is arranged in the connection zone 8 of the connection contact 2 or of the stacked plates 6, 9 that form the connection contact 2. In the exemplary embodiment, the crimp clamp 12 consists of a strip of sheet metal that is first bent into a U-shaped bracket (see Figure 1). Figure 1 The legs of the U-shaped bracket forming the crimp clamp 12 are inserted through openings 13 in the layered sheets 6, 9 of the crimp connector 1. In the exemplary embodiment, the openings 13 are designed as slots on both sides of the recesses 10 in the sheets 6, 9, which form the recess 11 in the connection zone 8 of the crimp connector 1. The crimp clamp 12 inserted through the openings 13 in the sheets 6, 9 and the rivets hold the layered sheets 6, 9 in their congruent, stacked position relative to one another.

Die Quetschklemme 12 ist beziehungsweise wird so am Anschlusskontakt 2 des erfindungsgemäßen Quetschverbinders 1 angeordnet, dass ein Joch des U-förmigen Bügels, der die Quetschklemme 12 bildet, den elektrischen Leiter 3 auf einer der Vertiefung 11 im Anschlusskontakt 2 gegenüberliegenden Seite umschließt und Schenkel der Quetschklemme 12 auf beiden Seiten an dem elektrischen Leiter 12 vorbei verlaufen und durch die Durchbrüche 13 in den Blechen 6, 9 hindurch gehen und auf einer elektrischen Leiter 3 gegenüberliegenden Seite der Bleche 6, 9 um 90° umgebogen werden, um die Quetschklemme 12 mit dem Anschlusskontakt 2 zu verbinden. Die auf der Seite der Grundbleche 9 umgebogenen Enden der Quetschklemme 12 sind in Figur 4 zu sehen. Dadurch dass das Joch der Quetschklemme 12 den elektrischen Leiter 3 umschließt, umschließt die Quetschklemme 12 den elektrischen Leiter 3 auf der Seite des Anschlusskontakts 2, in der sich die Vertiefung 11 befindet, in der der elektrische Leiter 3 mit einem Teil seines Umfangs einliegt, durchgehend ohne Unterbrechung.The crimp terminal 12 is arranged on the connection contact 2 of the crimp connector 1 according to the invention such that a yoke of the U-shaped bracket forming the crimp terminal 12 encloses the electrical conductor 3 on one side opposite the recess 11 in the connection contact 2 and legs of the crimp terminal 12 on both sides of the electrical conductor 12 run past and pass through the openings 13 in the plates 6, 9 and are bent 90° on the side of the plates 6, 9 opposite the electrical conductor 3 in order to connect the crimp terminal 12 to the terminal contact 2. The ends of the crimp terminal 12 bent on the side of the base plates 9 are in Figure 4 to be seen. Because the yoke of the crimp terminal 12 encloses the electrical conductor 3, the crimp terminal 12 encloses the electrical conductor 3 on the side of the connection contact 2, in which the recess 11 is located, in which the electrical conductor 3 lies with part of its circumference, continuously without interruption.

Zur Herstellung einer erfindungsgemäßen Quetschverbindung 14 wird der elektrische Leiter 3 in der Vertiefung 11 in der Verbindungszone 8 des erfindungsgemäßen Quetschverbinders 1 und zwischen den Schenkeln der U-förmigen Quetschklemme 12 angeordnet, die durch die die Durchbrüche 13 bildenden Schlitze beiderseits der Vertiefung 11 gesteckt werden. Der elektrische Leiter 3 ist beispielsweise ein Kabel, insbesondere ist er eine Litze, deren abisoliertes Ende in der Vertiefung 11 zwischen den Schenkeln der Quetschklemme 12 angeordnet wird. Anschließend werden die Quetschklemme 12 an ihrem Joch in Richtung der Bleche 6 gedrückt, wodurch der elektrische Leiter 3 von der Quetschklemme 12 in die Vertiefung 11 in der Verbindungszone 8 des Quetschverbinders 1 gespannt und zwischen der Vertiefung 11 und der Quetschklemme 12 festgeklemmt wird.To produce a crimp connection 14 according to the invention, the electrical conductor 3 is arranged in the recess 11 in the connection zone 8 of the crimp connector 1 according to the invention and between the legs of the U-shaped crimp clamp 12, which are inserted through the slots forming the openings 13 on both sides of the recess 11. The electrical conductor 3 is, for example, a cable, in particular a stranded wire, the stripped end of which is arranged in the recess 11 between the legs of the crimp clamp 12. Subsequently, the crimp clamp 12 is pressed at its yoke towards the plates 6, whereby the electrical conductor 3 is clamped by the crimp clamp 12 into the recess 11 in the connection zone 8 of the crimp connector 1 and clamped between the recess 11 and the crimp clamp 12.

Enden der Schenkel der Quetschklemme 12 werden auf der gegenüberliegenden Seite, also auf der Seite der Grundbleche 9 umgebogen derart, dass die Quetschklemme 12 mit den Blechen 6, 9 verbunden ist und den elektrischen Leiter in der Vertiefung 11 festspannt.The ends of the legs of the crimp clamp 12 are bent over on the opposite side, i.e., on the side of the base plates 9, in such a way that the crimp clamp 12 is connected to the plates 6, 9 and clamps the electrical conductor in the recess 11.

Um einen mechanischen Halt des elektrischen Leiters 3 in seiner Längsrichtung in der Quetschklemme 12 zu verbessern, eine Sicke in das Joch der Quetschklemme 12 geprägt, die sich innen im Joch der Quetschklemme 12 in den elektrischen Leiter 12 einformt und dort eine Vertiefung 19 bildet, die in Figur 1 gezeichnet ist. Die Sicke der Quetschklemme 12 kann allgemein auch als Vorsprung 20 in der Quetschklemme 12 aufgefasst werden, die sich in den elektrischen Leiter 3 eingeformt und dessen mechanischen Halt in seiner Längsrichtung in der Quetschklemme 12 verbessert.To improve the mechanical retention of the electrical conductor 3 in its longitudinal direction within the crimp terminal 12, a groove is embossed into the yoke of the crimp terminal 12, which forms a recess 19 inside the yoke of the crimp terminal 12 and is formed there in the electrical conductor 12. Figure 1 is drawn. The groove of the crimp clamp 12 can also generally be referred to as a projection 20 in the The crimp terminal 12 is formed into the electrical conductor 3 and improves its mechanical hold in its longitudinal direction in the crimp terminal 12.

Die den elektrischen Leiter 3 im Ausführungsbeispiel bildende Litze weist einen Leitungsquerschnitt ohne Isolierung von beispielsweise 125mm2 und einen Leitungsdurchmesser ohne Isolierung von beispielsweise 25-28mm auf. Eine senkrecht zum Anschlusskontakt 2 auf das Joch der Quetschklemme 12 ausgeübte Presskraft zum Festklemmen des elektrischen Leiters 3 in der Quetschklemme 12 und in der Vertiefung 11 in der Verbindungszone 8 des Quetschverbinders 1 beträgt beispielsweise 20 t (Tonnen). Die Schenkel der Quetschklemme 12 werden beim Pressen seitlich von außen abgestützt, damit sie sich nicht nach außen biegen können.The stranded wire forming the electrical conductor 3 in the exemplary embodiment has a conductor cross-section without insulation of, for example, 125 mm² and a conductor diameter without insulation of, for example, 25–28 mm. A pressing force exerted perpendicular to the terminal contact 2 on the yoke of the crimp terminal 12 to clamp the electrical conductor 3 in the crimp terminal 12 and in the recess 11 in the connection zone 8 of the crimp connector 1 is, for example, 20 t (tons). The legs of the crimp terminal 12 are supported laterally from the outside during pressing to prevent them from bending outwards.

Bei dem Festquetschen der den elektrischen Leiter 3 bildenden Litze werden die Einzeldrähte der Litze an die Stufen an den Seiten der Vertiefung 11 in der Verbindungszone 8 angeformt, wodurch zum Einen eine mechanisch feste Verbindung des elektrischen Leiters 3 mit dem Quetschverbinder 1 der erfindungsgemäßen Quetschverbindung 14 und zum anderen eine elektrisch gut leitende Verbindung mit niedrigem elektrischem Übergangswiderstand zwischen dem elektrischen Leiter 3 und dem Quetschverbinder 1 erreicht wird.When the strand forming the electrical conductor 3 is crimped, the individual wires of the strand are formed against the steps on the sides of the recess 11 in the connection zone 8, thereby achieving, on the one hand, a mechanically tight connection of the electrical conductor 3 with the crimp connector 1 of the crimp connection 14 according to the invention and, on the other hand, an electrically conductive connection with low electrical contact resistance between the electrical conductor 3 and the crimp connector 1.

Der erfindungsgemäße Quetschverbinder 1 beziehungsweise die erfindungsgemäße Quetschverbindung 14 ist geeignet für elektrische Stromstärken von einigen 100 A (Ampere), beispielsweise 800 A oder mehr und zum Anschluss von oder an elektrischen Stromquellen mit einer elektrischen Spannung von einigen 100 V (Volt), beispielsweise 1.000 V oder mehr. Eine mögliche beziehungsweise vorgesehene Verwendung des erfindungsgemäßen Quetschverbinders 1 beziehungsweise der erfindungsgemäßen Quetschverbindung 14 ist ein Anschluss einer beziehungsweise an eine Fahrbatterie/Akkumulator eines elektrisch angetriebenen Kraftwagens, insbesondere eines elektrisch angetriebenen Lastkraftwagens.The crimp connector 1 or crimp connection 14 according to the invention is suitable for electrical currents of several hundred amperes, for example 800 A or more, and for connecting to or to electrical power sources with an electrical voltage of several hundred volts, for example 1,000 V or more. A possible or intended use of the crimp connector 1 or crimp connection 14 according to the invention is for connecting to or to a traction battery/accumulator of an electrically powered motor vehicle, in particular an electrically powered truck.
