Definitions

  • the invention relates to an electrical contact element comprising a socket contact and a contact holder, according to the preamble of claim 1.
  • Connectors in particular connector sockets of the type mentioned above, are also referred to as RADSOK connectors and are characterized in particular in that their contact area is cage-like, that is, that a cylindrical or semi-cylindrical hollow body is designed, which preferably has contact blades in the longitudinal direction or contact spring arms for contacting with a plug pin.
  • socket contacts of the type mentioned are usually made as stamped / bent parts of a metal sheet.
  • cylindrical socket contact elements which are also stamped from a metal sheet, wherein the cylindrical socket body is produced by rolling or bending and rolling of the punching plate.
  • Such a connector is for example from the DE 197 34 524 C2 known.
  • a cylindrical socket contact consisting of a contact part and a connector, shown, wherein the contact part has a cylinder shell and the cylinder jacket is formed at least one stamped from the jacket contact spring tongue, which dive into the receiving area of the cylinder, so that a pin with these spring contact elements can contact as soon as it is plugged into the cylindrical socket contact.
  • Another cylindrical socket contact is from the DE 3702012 known. There is disclosed a manufacturing method for producing a tubular end piece.
  • FIG. 3 to FIG. 5 a RADSOK socket is shown there, which is provided with a connection socket on the outer sleeve of the RADSOK socket.
  • Difficulties in the RADSOK sockets of the aforementioned type are that it is difficult to produce a line, so an electrical connection with a line and a connection element.
  • a likewise substantially cylindrical contact is shown, which shows as a female connector, with a plurality of contact areas hyperbolically arranged in a contact section of the plug socket for electrically contacting a plug part which can be coupled to the plug socket.
  • the plug-in bush is here formed in one piece and in particular made of a one-piece stamped part, which is bent into the shape of the socket, with simultaneous punching of a suitable contact terminal portion is formed here as a crimp with multiple Crimplappen.
  • An electrical cable of different cable diameters can be connected to this connection box.
  • the receiving area of the smallest male conductor cross-section and the largest male conductor cross-section to be accommodated is limited by the specific geometry of the crimp terminal.
  • connection region plays a role relative to the contact arrangement, so that simple rectilinear contact connection regions can be formed, but on the other hand it is also desirable through installation positions to produce a different connection geometry.
  • Another requirement for a good contact system is the requirement for a high current carrying capacity with safe contact holding force of the Contact on a corresponding pin or counterpart, that is, it is desirable to create a contact geometry as possible so that it is solid and stable, but on the other hand, but inexpensive to manufacture and actual.
  • Such a contact system consisting of a contact element, which is designed as a hyperbolically rotated contact element, which in turn is pressed in a substantially cylindrical contact holder.
  • This contact holder can, as shown in this document in Figs. 9 and 10, be formed in a straight line and depending on the requirements in different lengths.
  • a 90 ° angled connection region that is to say a connection geometry, can also be formed perpendicular to the insertion direction of the contact element.
  • Generic connector systems is therefore common that they have a Maisganggangs Scheme between contact element and contact holder, ie connection area, which is typically regarded as a weak point of the overall system.
  • this transition region limits the service life of the contact system and, on the other hand, limits the electrical transmission properties. With regard to the service life, failures can occur at the transitional area due to thermal, mechanical or corrosive stresses which render the contact inoperable, or the contact holder with its connection area separates from the contactor element.
  • Another object of the present invention is to make the connection of the contact element with the contact holder so that one and the same contact element with a plurality of similar but with manufacturing tolerances affected contact holder can be brought into a secure and high-strength connection.
  • An additional object of the present invention is to be able to equip known contact systems with the contact holders according to the invention, without having to change the previous manufacturing processes for such contact systems; speak to eliminate the production-related shape and position tolerances of existing systems by the contact holder.
  • a contact element consisting of a socket contact and a contact holder, which is designed as Aufschrumpfcardhalter.
  • the socket contact itself consists of a cylindrical socket contact cage, also referred to as a so-called RADSOK cage, and a cylindrical bushing sleeve, in which the cylindrical socket contact cage is formed.
  • the contact cage and the female contact sleeve form the female contact, which is suitably connected to the shrink-on contact holder.
  • the cylindrical socket contact is thus connected to a thermally shrinkable contact holder, also referred to as a shrink-fit contact holder, by thermal shrinking.
  • the contact holder is provided with a substantially cylindrical opening which is made smaller in its inner diameter, such as the outer diameter of the corresponding cylindrical socket contact.
  • the inner diameter of the contact holder can be set defined with a suitable choice of temperature during heating and cooling the normal force on the cylindrical tube jacket, This gives a very tight interference fit between the contact holder and the socket contact, which is permanently stable and a high current carrying capacity.
  • the inner surface of the contact holder which serves as a contact surface to the cylindrical tube shell, geometrically structure in which, for example, a variety of finest grooves along the inner surface are mounted, which then impress on cooling in the tubular jacket, and to a enlarged contact surface and thus lead to improved current carrying capacity.
  • a contact element 1 is shown. This consists of a substantially cylindrical socket contact 2 and a contact holder 3 attached thereto.
  • the contact holder 3 is fixedly connected to a cable 4.
  • the socket contact 2 is formed as a substantially cylindrical socket contact with a cylindrical tube shell 21.
  • a contact cage 20 is fitted, as in Fig. 3 shown.
  • the contact holder 3 is embodied here as a shrink-on contact holder and is designed essentially as an annular element 30 and a connection section 31.
  • the connection section 31 connects the ring element 30 with the cable 4.
  • the contact holder 3 is formed so that a cable 4 in the 90 ° outlet, that is arranged perpendicular to the insertion direction S of the contact element 1.
  • the outer diameter of the tubular jacket 21 is defined as diameter D1.
  • the inner diameter of the ring member 30 is provided with a diameter D2, wherein the diameter D2 of the ring member 30 is formed smaller, such as the diameter D1 of the tube shell 21.
  • the inner diameter D2 is formed only slightly smaller than the outer diameter D1 of the tube shell 21.
  • the diameter D2 can also be significantly reduced compared to the outer diameter D1, so that in the process of applying the contact holder 3 to the socket contact 2, a high temperature is necessary to the ring member 30 corresponding to the diameter D2 expand a diameter greater than D1.
  • Fig. 2 is a bottom view of the contact element 1 according to the invention, according to Fig. 1 , shown.
  • the middle contact cage portion 23 In the inner region of the middle contact cage portion 23 is shown, with the diameter D3, which can be widened when plugged with a korrespondlerenden mating connector.
  • retaining slats 25 At the upper edge there are retaining slats 25, which are bent back around a further cylindrical pipe section, namely the cylindrical pipe sleeve 22 back and thus are firmly connected to the pipe sleeve.
  • the outer portions of the retaining louvers 24 are based on their outer surface 26 at the Inner wall surface 27 of the cylindrical tube shell 21 from.
  • the socket contact both from the one, as well as from the other direction stuck because it has an opening 29 on both sides.
  • the opening 29 tapers toward the center contact cage portion 23 increasingly by torsion of the contact cage 20, as in FIG Fig. 3 clearly visible. This is due to a relative movement, thus a rotation of the upper annular ridge 28 relative to the lower annular ridge 28 by a defined angle.
  • the middle contact cage portion 23 is formed, which can be formed with increased torsion optionally with a smaller diameter or weaker torsion with a larger diameter.
  • the cylindrical tube sleeve 22 is fitted in the cylindrical tube jacket 21 and pressed by means of the retaining lamellae 25 with this.
  • Fig. 4 can be seen, is the perspective view of a contact element according to the invention, in which the contact holder is connected as a 90 ° outlet with a cable 4. Alternatively, of course, any other geometric connection angle or shape can be chosen.
  • a ring element 30 with stepped inner diameter D2, so that when expanding to a diameter, greater D1, simultaneously several preferably parallel circumferential ring sections, with different inner diameter and cooling the contact holder 3 according to the outer diameter D1 optimally by means of trained annular sections shrink on the tube material 21 and can be connected with a press fit.
