Definitions

  • the invention relates to an electrical ribbon cable with at least one on one Carrier, in particular a carrier film, arranged flat electrical conductor track according to the features of the preamble of claim 1.
  • Such electrical ribbon cables are known and are used wherever not enough space is available for standard round cables, which also go also have a higher weight compared to ribbon cables.
  • To contact such ribbon cables with other ribbon cables or with electrical, Electronic or similar devices or modules require the ribbon cable to be provided with a connector.
  • For contacting the conductor tracks with a connector it is known that the conductor track is soldered to the connector becomes. Since the ribbon cable, especially when used in harsh environmental conditions, tensile or compressive forces also act on the conductor track strain relief is provided in the form of one on the connector arranged tab is at least partially placed around the conductor track and on a way that is mechanically deformed that this tab the conductor track pierces.
  • the invention is therefore based on the object of having an electrical ribbon cable to provide a connector with which the above described Disadvantages are avoided.
  • the conductor track is at least partially at one end is exposed in an electrically conductive manner and is folded over at least once, the exposed one and folded end with a connector, in particular a plug or Socket is connected.
  • a connector in particular a plug or Socket is connected.
  • This increases the otherwise very thin cross section of the Conductor, so that a higher current flow due to the increased cable cross section is possible, but due to the enlarged cross section also a higher one mechanical stability for contacting the connector is available.
  • soldering or similar processes can advantageously be avoided, so that the conductor track only by mechanical deformation of part of the Connector is connected.
  • the folding of the conductor track in the contact area has furthermore the advantage that the superimposed conductor track sections before external influences, especially moisture and temperature influences, are protected, so that the contact security is improved.
  • the connector has a crimp contact, wherein the exposed and folded end of the conductor track by mechanical deformation of the Crimp contact is set in this. Due to the mechanical deformation of the Crimp contacts is given strain relief on the one hand, so that further means for a Strain relief can be omitted, but not necessarily.
  • the mechanical Forming in such a way that the area of the folded-over conductor track sections (where in particular there are also carrier and / or cover foils in between can be pressed together by the crimp contact (or more), whereby contact security increases further. It also folds the area Conductor sections enclosed by the crimp contact, so that a contact area arises from external influences, in particular moisture and temperature influences, is protected. Depending on the design of the crimp contact can also be achieved be that this contact area is completely gastight.
  • the exposed end of the conductor track becomes multiple folded over. This increases the cable cross-section in the contact area with the Connector, so that the contact reliability is further improved. Moreover the multiple folding has the advantage that overall due to the otherwise right thin conductor tracks, a thicker end of the ribbon cable is available, which in handling, in particular in contacting with the connector, leads to a simplification.
  • the conductor track is exposed on both sides. Consists the ribbon cable from a plurality of interconnects arranged in parallel to each other are arranged on the one hand on a carrier film and on the other hand by a cover film are advantageously protected from folding and contacting the connector the end areas of one or more conductor tracks both from the Carrier film as well as the cover film freed, so that only the complete electrical conductive area of the conductor track comes into contact. Alternatively, it is possible that the conductor track is only exposed on one side, d. that is, either the Carrier film or the cover film remains on the conductor track. This reduces the Most of the effort involved in preparing the ribbon cable for contacting constant contact security.
  • a conductor track with a plug connector connected so that after connecting the folded conductor tracks with the Connectors at one end of the ribbon cable several parallel to each other arranged connectors are available. These can be in an associated Contact partners are inserted, it being used to improve handling and Avoid touching the individual connector means are provided able to keep the parallel connectors at a distance. This can be done in particular that several connectors, especially all Connectors that are connected to the conductor tracks are surrounded by a housing become.
  • This housing can for example consist of two halves, the Plug connector inserted into one half of the housing and through the second half of the housing be determined. Alternatively, it is conceivable that the individual connectors in their position relative to each other and then overmolded with plastic.
  • the connector has wings that according to the mechanical forming the conductor track on the connector, without the To pierce the conductor track. This makes another one in addition to the crimp contact Strain relief given that the contact area of the crimp contact before pull and Relieves pressure forces without mechanically damaging the conductor track.
  • FIG. 1 shows the various steps involved in making a ribbon cable to be provided with a connector in the manner according to the invention.
  • a ribbon cable 1 has at least one conductor track 2, usually several Conductor tracks 2 are arranged parallel to one another and form the ribbon cable 1.
  • These conductor tracks 2 are covered and located on the one hand by a cover film 3 on the other hand on a carrier film 4, the cover film 3 and the carrier film 4 being made of may consist of different or the same material and the same or different are fat.
  • a first step the conductor track 2 on both sides of the Cover film 3 and freed from the carrier film 4.
  • this will be exposed end of the conductor track 2 folded over and in a third step the end area of the conductor track which has been folded over is folded over again.
  • the outermost conductor packet is folded over again, so that a End of trace 2 is available, which now consists of five superimposed Conductor sections exist.
  • a connector 5 which is contacted with the conductor track end prepared in this way should consist, for example, of a contact pin 6 and has a barb 7 provided, which prevents the connector 5 after insertion into a Housing (not shown here) can be pulled out of this. Furthermore points the connector 5 has a crimp contact 8, in the area of which the folded end of the Track 2 is inserted. The contacting in this area of the crimp contact 8 will be described for Figures 3 and 4. Another, shown at the bottom right in FIG. 1 Connector 5 can additionally have a strain relief 9, which by mechanical forming around the end region of the ribbon cable 1 with cover film 3 and Carrier film 4 is placed to realize a further strain relief without that Ribbon cable 1 is mechanically damaged. Such strain relief 9 can, must but not be provided on the connector 5.
  • Figure 2 shows in the upper and middle third of a ribbon cable 1, in which the The conductor track is freed from its cover film 3, but the carrier film 4 is still present.
  • a four-layer cross section 10 results or a double-layer cross section 11 of the end region of the conductor track 2, also even more than one or two folds and also other folds than they are described in Figures 1 and 2, are conceivable.
  • the connector 5 with which the folded area of the conductor track 2 should be connected.
  • FIGS. 3 and 4 show a section through the area of the crimp contact 8 of contacting.
  • the layers alternate a conductor track 2 and a carrier film 4 (FIG. 3) or the same Layers lie one above the other (see FIG. 4), this being the double-layer cross section 11 corresponds to the middle illustration in FIG. 2.
  • the crimp contact 8 before contacting was open at the top and has two wing-like configurations, in front of the Contacting the folded end region of the conductor track 2 in the area of the wing-like Refinements is used and these wing-like configurations in the shown manner are mechanically reshaped, so that ultimately the Crimp contact 8 defines the conductor track package and makes electrical contact. Due to the Design of the crimp contact 8 are the conductor track sections (and, if necessary the foils in between) are compressed, creating a gas-tight seal and reliable connection results.
  • FIG. 5 shows, in addition to a first ribbon cable 1, a further ribbon cable 13, which also has at least one conductor track 14 and corresponding cover films 15 and carrier foils 16.
  • the correspondingly prepared ends of the conductor tracks 2 and 14 are folded together (as shown in Figure 5) or individually folded and then into a contact area 17, i.e. H. inside the crimp contact 8.
  • the mechanical deformation of the crimp contact takes place, so that the conductor tracks 2 and 14 in the contact area 17 mechanically and be electrically connected to each other.
