Definitions

  • the present invention relates to a fastening system for fastening a cable lug in a motor vehicle.
  • Cable lugs are used in vehicles, among other things, to connect an electrical conductor with a vehicle-fixed nut or a vehicle-fixed bolt, in particular a ground bolt.
  • a plurality of cable lugs are usually attached to a common ground bolt or to a common vehicle-fixed nut.
  • the cable lugs where conductors are already attached, either plugged onto a vehicle-fixed ground bolt and then screwed with the help of a nut, or they are first placed vice on a screw, which is then bolted to a vehicle-fixed nut.
  • the problem here is, however, that the Installer must always have the appropriate screw or nut at hand, for example, if he wants to mount a cable harness with cable lugs in the vehicle. It has been proposed to use cable lugs with an integrated nut or screw, so that no additional parts are needed for assembly. However, this solution is not satisfactory, since a variety of different cable lugs with or without nut and with or without screw must be kept in stock.
  • the present invention is therefore an object of the invention to provide a fastening system for securing a cable lug in a motor vehicle, which allows quick and easy attachment using as few parts as possible.
  • the fastening system comprises, on the one hand, a fastener fastened to a complementary vehicle-fixed element and, on the other hand, a disk with a central opening.
  • the disk and the fastener have a common axis of symmetry which passes through the center of the central opening of the disk.
  • the disc is connected to the fastening element so that it can be rotated with respect to the fastening element about this common axis of symmetry, and is provided with locking elements by means of which it can be locked in rotation with a cable lug.
  • the fastening element may be, for example, a nut for screwing onto a ground bolt or a screw for attachment to a vehicle-fixed nut.
  • a connection plate of the cable lug comes to lie concentrically under the disc, so that the central opening of the disc and a central opening in the connection plate are concentrically superimposed.
  • This assembly step can already take place outside the motor vehicle and long before the actual assembly in a motor vehicle.
  • the fastening system according to the invention can be attached to one or more cable lugs of a wiring harness.
  • the fastening element of the fastening system according to the invention can be screwed to the vehicle, without the need for further fasteners such as screws or nuts would be needed.
  • the disc latched with the cable lug does not rotate during screwing, so that assembly is not hindered.
  • the locking elements for locking the disc with the cable lug recesses Preferably, axially projecting and provided with an opening latching projections are arranged in these recesses.
  • Such trained locking elements allow easy and durable locking with a cable lug.
  • corresponding latching recesses may be formed in the connection plate of the cable lug, through which the latching projections are inserted become.
  • the openings in the locking projections may optionally snap complementary locking tongues, which are provided in locking recesses in the connection plate of the cable lug.
  • two identically formed locking elements are arranged symmetrically with respect to the symmetry axis on the disc.
  • a non-rotatable and stable locking connection is possible with minimal effort.
  • gripping noses are formed on the outside, which points radially inward and engage in a groove provided on the fastening element.
  • the gripping tabs can slide along the groove so that the disc can be rotated with respect to the fastener.
  • For better retention of the disc on the fastener may serve a collar which extends parallel to the groove and holds the gripping tabs in the groove.
  • the disc is preferably made of a copper alloy.
  • the invention also relates to a method for producing a fastening system according to the invention.
  • a disk is first produced with a central opening, wherein gripping tabs protrude into the central opening and out of the plane of the disk.
  • the disc is then placed on a fastener, wherein the protruding from the plane of the disc gripping tabs come to lie above a groove in the fastener.
  • the gripping noses are now depressed, so that they point radially inward and engage in the aforementioned groove.
  • the gripping tabs can now slide in the groove around the fastener while a axial movement of the disc with respect to the fastener is prevented by the seated in the groove gripping noses.
  • the disc 10 is substantially annular with a central opening 14.
  • gripping lugs 16 are on the outside, which point radially inward.
  • Disc five gripping lugs 16 are provided, but it can also be a different number of gripping lugs 16 are selected.
  • the gripping tabs 16 are slightly tapered compared to the thickness of the disc 10 and also taper in the direction of the center of the opening 14th
  • a fastening system is shown in which the in Fig. 1 shown disc 10 is connected to a nut 30.
  • a circumferential groove 32 is formed in the region of one of the two axial ends of an internal thread 35, above which a parallel to the groove 32, outwardly projecting collar 34 is formed.
  • the gripping lugs 16 of the disc 10 engage in this groove 32 and are prevented by the collar 34 from moving out of the groove 32.
  • the disk 10 can thus be rotated with respect to the nut 30 with the gripping tabs 16 sliding in the groove 32.
  • Fig. 3 shows another embodiment of a fastening system in which instead of a nut 30, a screw 40 is used as a fastener. Again, the gripping lugs 16 of the disc 10 engage in a groove 32 which is now between the screw head 42 and the external thread 44 of the screw 40.
  • a collar 34 in Fig. 2 corresponding collar is in Fig. 3 not shown, but can of course be provided exactly as in the embodiment described above to improve the grip of the gripping lugs 16 in the groove 32.
  • two opposing recesses 20 are provided in the disc 10, which have the shape of circular ring sections with rounded corners.
  • the latching recesses 20 each have a latching projection 22 with an opening 24.
  • These latching projections 22 extend from the in the direction of the opening 14 in the disc 10 facing inner sides of the recesses 20 from initially in the plane of the disc 10 and then extend perpendicular to this plane in the axial direction.
  • the opening 24 formed in the latching projections 22 has a rectangular cross section and is dimensioned such that essentially only one frame-like edge remains of the latching projections 22.
  • the latching projections 22 extend in the circumferential direction over the entire width of the openings 20th
  • a suitable cable lug is in Fig. 4 shown and is already from the aforementioned EP 1 746 686 A1 known and described there in detail, so that he should be described here only briefly.
  • the cable lug 50, 50 ', 50 has a substantially circular terminal plate 54 and an elongated receiving portion 52 which adjoins the terminal plate 54. It is important to the present invention that in the center of the terminal plate 54 a circular opening 58 is provided, which corresponds in its dimensions in approximately the central opening 14 in the disc 10 of the fastening system according to the invention.
  • the recesses 56 have no further locking elements.
  • the thickness of these locking lugs 60 in the axial direction corresponds to the thickness of the connection plate 54, and the width of the latching lugs 60 is about 1 / 4 to 1/3 of the extent of a recess 56 'in the circumferential direction.
  • the width of the latching lugs 60 in the circumferential direction also corresponds to the width of the openings 24 in the latching projections 22 of the pane 10, so that the latching lugs 60 can engage in these openings 24.
  • recesses 56 "are provided in which locking projections 55 are arranged, which are exactly identical to the locking projections 22 in the openings 20 in the disc 10, and which serve several lugs 50, 50 ', 50" rotatably connected to each other (see. Fig. 5 ).
  • FIG. 5 is purely an example of a mounted arrangement of the in Fig. 3
  • the fastening system shown here is shown with one screw 40 and three cable lugs 50, 50 ', 50 ", the disk 10 underneath the lowermost cable lug 50' can not be seen, and the three lugs 50, 50 ', 50" can be latched radially offset from one another also using the above-described latching recesses 56, 56 ', 56 "with the corresponding latching elements, after which the lowermost cable lug 50' is connected to the pane 10 in the manner described above so that the three cable lugs 50, 50 ', 50 "are connected via the disc 10 rotatably connected to the screw 40.
