Definitions

  • the present invention relates to a flex foil contact arrangement according to the preamble of the independent claim as well as a flex foil conductor.
  • Flex foils are thin plastic foils on which one or several metallic conductor tracks, in particular Cu tracks, attached are. These flex foils are characterized by their small size Weight and due to the thin material by their Flexibility. With a correspondingly wide conductor track design are the foils not only for data signal transmission, but also for the energy supply of Can be used by consumers such as LEDs etc. It is also there already known, contact arrangements at the ends of the flex foils to be provided on which the flex film is contacted.
  • the object of the present invention is to create something new to provide for commercial use.
  • the solution this task is claimed independently. Preferred embodiments can be found in the subclaims.
  • a first essential aspect of the invention sees one Flex film connection arrangement with a contact surface for the Contact area of a supplied flex film and flex film recesses engaging means penetrating near the contact surface in which it is provided that the engagement means the Penetrate the flex film opposite the feed side.
  • a first basic idea of the invention is therefore by locating the engaging means away from both the trace as well as the contact area not just a general one To achieve fixation, but also a flat layer of the flex film at the contact area by placing an engaging force behind this is exercised.
  • protection for the contact area provided to such as prefabricated during transportation and lead foils provided with terminals, protecting them to cause, especially against kinking and / or soiling.
  • Protection can be provided by a general around the flex film end U-shaped, preferably with a groove circumferential border be formed, the protection continues may include an upper cover.
  • the groove-like grip the edge of the conductor foil at the contact area is per se, and especially regardless of the presence of a rear Flex film flat layer engaging means advantageous.
  • the cover can be provided a contact window and at the same time can also complete the cover with the cover bordered conductor track end to the conductor track except for one corresponding passage area can be effected.
  • the cover is in a preferred embodiment have a single contact window for all contact pins, the contact surface itself being longer than the contact area and the window above it will be so one Lying flat also in the contact areas if possible to ensure separable elongated holes in a preferred Example of use that form flexible film recesses.
  • the engagement means can be a plurality of pins or the like have, which penetrate through the conductor track and with this leaving in particular a sufficient lateral Play in positive engagement. It is on the feed side opposite side, that is close to or immediately at the end of the conductor track, preferably a single one Pin provided that the flex film only on the support surface must tighten, while preferably further pins are provided are to hold back the entire slide and so one To effect strain relief on the contacts.
  • cones are on the cover arranged so that when the lid is folded down the First step through the slots and then through the corresponding ones Recesses on or on the contact surface.
  • 1 comprises a flex foil contact arrangement, generally designated 1 1 a base 2 with a support surface 3 and a lid 4, which has a film hinge 5 with the base 2 is connected.
  • the base 2 has a generally U-shaped circumferential wall 6 provided, wherein the U is open on the feed side, so closed the side from which a flexible film end is inserted 3, the side walls 6 are open the height of the support surface 3 with a forward (feed side) lateral groove extending to the rear 7 provided.
  • a locking lug 8a for cooperation provided with a locking arrangement 8b, which as side cheeks are formed on the cover 4, around which the film hinge 5 to be able to snap-in cover 4.
  • the U-shaped side wall is close to the support area 3 lower than the feed side, the different heights Areas are connected to each other by a ramp 9.
  • a series of holding cams 11a facing the base are provided, in corresponding holding cam recesses 11b the base 2 intervene.
  • a pin 13a is provided centrally, which in an elongated Recess 13b in the base 2 can be pivoted.
  • the Pin 13a is directly next to a window 14 in the Cover 4 is provided, which has such a clear width, that contact finger 20 on a socket (see Fig. 5) can penetrate through the window 14.
  • a latching arrangement 8c for latching the arrangement provided in a socket.
  • the flex foil contact arrangement that is to say the flex foil plug according to the present invention is used as follows:
  • a flexible film 15 of suitable width 15 (compare Fig. 4) with elongated holes 16 and 17 before under behind provided their contact area 18.
  • the flex film 15 in the lateral grooves 7 between the wall 6 and base 2 of the Flex film contact assembly 1 inserted until it at the rear End of the flex foil contact assembly 1 abuts.
  • the flex film is now correctly aligned and against the side Move protected on base 2.
  • the Lid 4 swung down.
  • the pin 13a penetrates the slot 17, which between two conductor tracks 19a, 19b is arranged in a region 20 free of conductor tracks, and will then pivoted into the recess 13. This already results mechanical contact between pin 13a and the flex film 15 before the holding cams 11a close to the flex film are.
  • the flex film is pulled backwards and in Contact area streamlined. Then penetrate the holding cams 11a the elongated holes 16 in the flexible film 15 and get into the Retaining cam recesses 11b at the base 2. The flex film is pulled slightly inwards, for which the back, So beveled to the inside of the side edge of the Holding cam 11a then contributes to the side cheeks 8b Engagement with the locking cams 8a and the plug cover 4 is locked at the base.
  • the plug can now be inserted into a corresponding socket and there may be those in the socket existing contact pins in the socket on the conductor ends ultrasonically welded or otherwise permanent get connected.
  • FIGS. 5 to 8 show a further exemplary embodiment, which differs from the previous one only in that that instead of the elongated holes penetrating cams 11b of the first variant as a front engagement means Press cams 11b 'are provided which the flex film does not pierce, but push down and so also in Interaction with the rear pin 13a 'a flat position the flex film in the contact area.
