Embodiment Construction
[0047] Figures 1A-1D A device 10 for connecting an electrical contact part 16 to an electrical conductor 18 is shown in four different positions ( 1 ) to ( 4 ) that are representative of the connection method. The device 10 includes in particular a plunger 24 against which the contact part 16 abuts. The contact part 16 is made of metal in the exemplary embodiment and has legs 26 that lie opposite each other in pairs. Conductor 18 is loosely inserted between legs 26 . The conductor 18 is in the present embodiment a cable with a plurality of individual conductors or stranded wires 28 . In particular, for moment (1) ( Figure 1A ) A permanent connection has not yet been established between the contact part 16 and the litz wire 28 of the conductor 18 . In the present exemplary embodiment, the litz wire 28 is made of an electrically conductive metal. Finally, the device 10 also includes a bending plunger 12 configured as a counterpart to the plunger 24 . This makes it possibl...

The invention relates to a method for connecting an electrical conductor (18) to an electrical contact part (16), wherein the contact part (16) has deformable legs (26) and the legs (26) are deformed by means of a bending die (12) in such a way that the legs press the conductor (18) with the contact part (16) in a force-locked manner, wherein the contact part (16) is acted upon in such a way that at least the legs (26) are connected to each other in a bonded manner. The invention further relates to a device (10) having a bending die (12) for connecting an electrical conductor (18) to an electrical contact part (16), wherein the contact part (16) has deformable legs (26) and the bending die (12) is designed to deform the legs (26) in such a way that the legs press the conductor (18) with the contact part (16) in a force-locked manner, and wherein the device also comprises a laser welding device (20), wherein the laser welding device (20) is designed to act on the contact part (16) in such a way that at least the legs (26) are connected to each other in a bonded manner.
Description
technical field [0001] The invention relates to a method for connecting an electrical conductor to an electrical contact part, wherein the contact part has a deformable leg, and the leg is deformed by means of a bending punch / die in such a way that the conductor is pressed against the contact part in a non-positive manner together. The invention also relates to a device with a bending plunger for connecting an electrical conductor to an electrical contact part, wherein the contact part has a deformable leg and the bending plunger is designed such that the leg deforms such that the leg makes the conductor Squeeze together non-positively with the contact parts. Background technique [0002] In the case of electronic and electrical components of a vehicle, such as the on-board electrical system of a vehicle, the connection of the contact parts to the conductors is usually achieved by means of a mechanical, non-positive connection, a so-called crimp connection. In the crimping...
