In a housing of an electrical appliance, in particular an electric motor for driving vehicle wheels usable insulating molding wipers

The innovation relates to an in a housing of an electrical Device, in particular an electric motor for driving vehicle windshield wipers, an insulating material molded part from the outside of which has at least one connection rail for an electrical Line and from its inside with the connecting rail electrically connected contact spring strip protrudes.

In previously known insulating molded parts of this type are the Connection rail and the contact spring strip by a rivet or a screw is attached to the insulating material part and connected to one another so as to conduct electricity. Special precautions are to be taken here meet so that the connecting rail and in particular the contact spring strip be held in the prescribed position.

In the case of other known molded insulating parts, the ones mentioned at the beginning Type are the connecting rail and the contact spring strip formed from a single piece of wire that is passed smoothly through the insulating material. This design is preferred only suitable for miniature motors, their power supply lines soldered to the connection-side ends of the pieces of wire and whose wire pieces are therefore not exposed to any significant mechanical stresses.

The innovation is the object of the invention to provide a simple and inexpensive fixing of the connecting bar and the contact spring strip to the insulating material that does not require additional fasteners such as rivets, screws, lock washers and the like and yet perfect a tight fit, the exact location and Electrically conductive connection of the parts guaranteed.

To solve this problem it is proposed according to the innovation that the connecting rail and the contact spring strip with angled, firmly connected end sections are anchored in the insulating material.

In the drawing, an exemplary embodiment of the subject of the innovation is shown for driving vehicle windshield wipers Serving efektromotor including a motor supporting ...
