Definitions

  • the invention relates to a ribbon cable with a contact device and an electrical device with such a cable.
  • Ribbon cables FFC
  • FFC Ribbon cables
  • the connections are easy to produce, but have the disadvantage that they can easily be unintentionally detached. Therefore, strain reliefs are known in the prior art which are arranged on the contact device and which cooperate with corresponding configurations of the plug devices and thus prevent the contact device from being released from the plug device.
  • the disadvantage here is that the contact device is only complex and complicated to assemble.
  • the object of the invention is to provide a ribbon cable with a contact device and strain relief, which is easy to assemble.
  • strain relief is arranged away from the contact device. This separation of the function of the electrical connection and mechanical strain relief means that the contact device can simply be inserted into the
  • Plug device are introduced. Furthermore, the printed circuit board on which the plug device is arranged is not mechanically loaded by the ribbon cable if the pulling Relief cooperates with a holding device that is not arranged on the circuit board. If the strain relief is designed as a recess of the ribbon cable, this recess can interact with a holding device, wherein this holding device can be connected to a device housing or can be designed as part of a device housing. These holding devices can be designed, for example, as bolts or projections which engage in the recesses in the ribbon cable. It is also possible to guide fixing elements such as screws or rivets through the recesses and thus fasten the ribbon cable accordingly.
  • the ribbon cable is particularly easy to install if the strain relief is designed as a thickening, widening or folding of the ribbon cable.
  • the strain relief can be achieved in that the cable is guided through a gap and the gap has dimensions such that the strain relief cannot pass the gap and thus has the effect of relieving the strain.
  • Such a gap can be implemented particularly easily in the housing of an electrical device. The forces that occur are introduced into the housing so that the circuit board is not mechanically stressed by the cable.
  • the ribbon cable according to the invention can also advantageously be used in electrical devices which comprise two housings, one housing being movable relative to the other, in particular if the second housing is movable about a pivot point in relation to the first.
  • the electrical functions that are located within the two housings can be easily and safely connected electrically using the ribbon cable.
  • FIG. 2 shows the side view of the ribbon cable from FIG. 1 in the installed state
  • FIG. 6 is a side view of a strain relief in a fifth embodiment
  • Fig. 7 The side view of the ribbon cable from Figures 1 and 2 installed in an electrical device shown in section.
  • a ribbon cable 1 has a contact device 2 with plug contacts 2a and a strain relief in the form of a thickening 3.
  • the contact device 2 shown consists of an stripped end of the ribbon cable 1; however, it is also possible to provide a plug as the contact device 2, which is connected directly to the cable 1.
  • the thickening can be made of the insulation material of the ribbon cable or another material, preferably foam rubber.
  • the thickening 3 is arranged at a distance from the contact device 2. It has proven to be advantageous if the distance a between the strain relief and the contact device 2 is at least 7 mm. It is also possible to arrange the thickening on both sides of the ribbon cable 1.
  • FIG. 2 it can be seen that the contact device 2 is inserted into a plug-in device 4 with contacts 4a, which is attached to a circuit board 5 and is electrically connected to it.
  • the contacts 4a touch the plug contacts 2a and thus establish the electrical connection between the ribbon cable 1 and the plug device 4.
  • part of a housing 6 can be seen in FIG. 2 with the outside 6a and with a gap 7 through which the ribbon cable 1 is guided. A further passage of the cable 1 is prevented by the thickening 3, which does not fit through the gap 7.
  • the contact device 2 cannot be pulled out of the plug device 4 by pulling the cable 1 outside the housing 6. Due to the distance between the thickening 3 and the contact device 2, the contact device 2 can be inserted into the plug device 4 simply and quickly. Forces that act on the ribbon cable 1 outside the housing 6 do not load the circuit board 5, since the forces are transmitted to the housing 6 via the thickening 3.
  • the cable 1 has a strain relief in the form of a widening 8. This effectively prevents the cable from being pulled further out through the gap 7 of the housing 6 (to the left in the plane of the drawing).
  • the widening 8 can be made by one-piece configuration. tion of the cable foil of the ribbon cable 1 can be realized or by gluing a foil material or other material onto the ribbon cable 1. In the one-piece design, an additional operation (the additional fastening) is saved.
  • bolts 10 can be seen which protrude into the recesses 9.
  • the bolts 10 can be mechanically connected to the housing 6 or can be designed as part of the housing 6.
  • the form of the strain relief described above can be produced in one piece with the ribbon cable, but the usable width of the ribbon cable 1 is restricted by the recesses 9.
  • the ribbon cable 1 has recesses 11, which are arranged in a widening 12.
  • the widening 12 can be produced like the widening 8 in FIG. 3.
  • Bolts or screws 13 can be guided through the recesses 11, for example, which in turn are mechanically connected to the housing.
  • the recesses 9, 11 provide strain relief in both longitudinal sides of the ribbon cable 1 (to the left and right in the plane of the drawing).
  • FIG. 6 A further form of strain relief is shown in FIG. 6.
  • the ribbon cable 1 has folds 14a, 14b which prevent the cable from being pulled out of the housing 6 (to the left in the plane of the drawing) up to a certain force.
  • the folds can be reinforced by an adhesive 14c between adjacent sections of the ribbon cable 1 or a binder 14d.
  • 7 shows the use of a flat ribbon cable 1 according to the invention from FIGS. 1 and 2 in an electrical device with housings 15 and 16.
  • the housing 15 can be rotated about an axis of rotation 17 relative to the housing 16 and has a gap 18.
  • the cable 1 has recesses in the area of the housing 16, as in FIG. 5, through which bolts 21 are guided.
  • the recess into which a bolt 21 engages can also be arranged centrally in the cable, so that a bolt 21 is sufficient for securing.
  • the cable is secured by the thickening 3 in the area of the housing 15.
