Definitions

  • the invention relates to an electrical ribbon cable with at least one arranged on a support, in particular a carrier film, flat electrical conductor track according to the features of the preamble of claim 1.
  • Such electrical ribbon cables are known and are used where not enough space for conventional round cable is available, which also have a higher weight compared to ribbon cable.
  • the conductor is soldered to the connector.
  • a strain relief is additionally provided in the form that a arranged on the connector tab is at least partially placed around the conductor around and on a way is mechanically deformed, that this tab pierces the conductor track.
  • the arrangement of the connector by crimping takes place only in an area to the left of the dividing line, wherein after crimping the ribbon cable along the dividing line is folded, which can be seen in Figure 5.
  • This means that the exposed portion of the track for crimping the connector is only partially exposed and retains its original shape both before and after crimping. Because only after the connector has been crimped to the partially exposed end or region of the ribbon cable, the refolding of the ribbon cable, without affecting the contact region of the connector or its conductor is effected.
  • the invention is therefore an object of the invention to provide an electrical ribbon cable with a connector available, with which the above-described disadvantages are avoided, and improves the contacting of an electrical conductor of a ribbon cable to a crimp.
  • the conductor is fully electrically conductive exposed at one end and folded over at least once, wherein the exposed and folded end with a connector, in particular a plug or a socket is connected and the connector has a crimp contact, wherein the exposed and folded End of the conductor is determined by mechanical deformation of the crimp contact in this.
  • This increases the otherwise very thin cross-section of the conductor, so that a higher current flow is possible due to the increased line cross section, at the same time due to the enlarged cross section and a higher mechanical stability for contacting with the Connector is available.
  • this soldering or similar processes can be avoided, so that the conductor is connected only by mechanical deformation of a part of the connector.
  • the folding over of the conductor track in the contact area moreover has the further advantage that the superimposed conductor track sections are protected against external influences, in particular against moisture and temperature influences, so that the contact reliability is thereby improved.
  • the mechanical deformation of the crimp contacts Due to the mechanical deformation of the crimp contacts, on the one hand there is a strain relief so that further means for a strain relief can be omitted, but need not.
  • the mechanical deformation is carried out in such a manner that the area of the folded conductor track sections (where in particular even carrier and / or cover sheets may intervene) of the crimp contact (or more) are compressed, whereby the contact reliability increases further.
  • the area of the folded conductor track sections is enclosed by the crimp contact, so that a contact area is formed, which is protected from external influences, in particular moisture and temperature influences. Depending on the configuration of the crimp contact can also be achieved that this contact area is completed completely gas-tight.
  • the exposed end of the conductor is folded several times.
  • the line cross section increases in the contact region with the connector, thereby further improving the contact reliability.
  • the multiple folding has the advantage that overall due to the otherwise fairly thin conductor tracks, a thicker end of the ribbon cable is available, which leads to a simplification in handling, especially when contacting the connector.
  • a plurality of interconnects are connected to the connector.
  • a flat-ribbon cable which has a plurality of interconnects arranged parallel to one another to connect two or more interconnects to a single connector.
  • the track is exposed on both sides.
  • the ribbon cable consists of a plurality of mutually parallel conductor tracks, which are arranged on the one hand on a carrier film and on the other hand protected by a cover sheet, advantageously the end portions of one or more tracks both from the carrier film and from before folding and contacting the connector the cover sheet freed, so that only the fully conductive electrically conductive area of the conductor comes to the contact.
  • a conductor track is in each case connected to a plug connector, so that a plurality of mutually parallel connectors are available after the connection of the folded conductor tracks to the connector at one end of the ribbon cable.
  • These can be plugged into an associated contact, and it can be provided to improve the handling and to avoid contact with the individual connectors means that keep the parallel connectors at a distance.
  • This can be done in particular by the fact that a plurality of connectors, in particular all the connectors which are connected to the conductor tracks, are surrounded by a housing.
  • This housing may for example consist of two halves, wherein the connectors are inserted into the one half of the housing and fixed by the second housing half.
  • the individual connectors are fixed in position to each other and then encapsulated in plastic.
  • the connector has wings which define the conductor track on the connector after the mechanical forming, without piercing the conductor track.
  • a further strain relief is provided, which relieves the contact area of the crimp contact from tensile and compressive forces without mechanically damaging the conductor track.
  • a method for contacting at least one printed circuit of a ribbon cable with a plug connector, in which the electrically conductive exposed region of the printed conductor is at least once folded over and connected to a plug connector.
  • This connection takes place in particular by mechanical deformation of a crimp contact on the Connector, wherein the package of the folded conductor track sections is compressed, whereby an increased contact safety and a strain relief is given.
  • FIG. 1 shows the various operations required to provide a ribbon cable with a connector in the manner of the present invention.
  • a ribbon cable 1 has at least one printed conductor 2, wherein a plurality of printed conductors 2 are generally arranged parallel to one another and form the flat-ribbon cable 1.
  • These interconnects 2 are on the one hand covered by a cover sheet 3 and on the other hand are on a carrier film 4, wherein the cover film 3 and the carrier film 4 may consist of different or the same material and are the same or different thickness.
  • a connector 5, which is to be contacted with the thus prepared conductor track end for example, consists of a contact pin 6 and is provided with a barb 7, which prevents the connector 5 after insertion into a housing (not shown here) are pulled out of this can.
  • the connector 5 has a crimp contact 8, in the region of which the folded end of the conductor 2 is inserted. The contacting in this area of the crimp contact 8 will be described with reference to FIGS. 3 and 4.
  • Another, shown in Figure 1 bottom right connector 5 may additionally have a strain relief 9, which is placed by mechanical deformation around the end portion of the ribbon cable 1 with cover sheet 3 and carrier film 4 in order to realize a further strain relief without the ribbon cable. 1 is mechanically damaged.
  • Such a strain relief 9 may, but need not be provided on the connector 5.
  • Figure 2 shows in the upper and in the middle third each a ribbon cable 1, in which the conductor is freed from its cover sheet 3, the carrier film 4, however, is still present.
  • the carrier film 4 is still present.
  • the connector 5 is again shown, with which the folded portion of the conductor 2 is to be connected.
  • Figures 3 and 4 show a section through the region of the crimp contact 8 after contacting.
  • the layers of a conductor track 2 and a carrier foil 4 alternate (FIG. 3) or identical layers are superimposed (see FIG. 4), this being the double-layered cross section 11 according to the middle illustration of FIG equivalent.
  • the crimp contact 8 was open prior to contacting up and has two wing-like embodiments, being used before contacting the folded end portion of the conductor 2 in the region of the wing-like embodiments and these wing-like embodiments in the shown manner are mechanically transformed, so that ultimately the crimp contact 8 defines the conductor track package and contacted electrically. Due to the configuration of the crimp contact 8, the conductor track sections (and optionally the intervening films) are compressed, resulting in a gas-tight and contact-secure connection.
  • FIG. 5 shows, in addition to a first ribbon cable 1, a further ribbon cable 13, which likewise has at least one conductor track 14 as well as corresponding cover foils 15 and carrier foils 16.
  • the correspondingly prepared ends of the tracks 2 and 14 are folded together (as shown in Figure 5) or individually folded and then into a contact area 17, d. H. within the crimp contact 8, inserted. Thereafter, as already described, the mechanical deformation of the crimp contact takes place, so that the conductor tracks 2 and 14 are mechanically and electrically connected to one another in the contact region 17.
