Abstract: A battery clamp comprises a connecting lug (12), a contact ring (10) which is provided with a slot so as to form two opposite clamping ends (14). Each clamping end includes a bent lug (16), and a slope (18). A spring (22) engages the clamping ends of the contact ring. A blocking wedge (28) is positioned between the bent lugs of the clamping ends and can be shifted between a mounting position in which it keeps the clamping ends of the contact ring in a spread condition, and a contact position in which it releases the clamping ends so that the spring can pull the clamping ends together.

Abstract: A battery clamp comprises a contact ring which can be placed on a battery contact, and a terminal bolt to which a cable can be screwed. The contact ring is formed from two metal lugs each continuing into an intermediate section in which they extend in parallelism to each other and spaced from each other. Adjacent thereto, the metal lugs continue into a terminal section in which the terminal bolt is arranged. A stiffening lug is provided which starting from the terminal section extends as far as between the two intermediate sections and is connected at this place with the two metal lugs in a fashion resistant to shearing load.

Abstract: A hermetically sealed housing for power electronics comprises a tank consisting of sheet metal, and a cover consisting of an aluminum material. The tank has a surrounding edge which is provided with a plurality of bending lugs, and the edge of the cover has a shoulder at which the bending lug rests, so that the cover is pressed against the edge of the tank and a hermetic sealing is obtained.

Abstract: A disconnector comprises a first conductor (10), a second conductor (14) which is mechanically connected with the first conductor (10) but electrically insulated therefrom, and a semiconductor switch (28) which provides an electrically switchable electric connection between the first and second conductors.

Abstract: The invention relates to a method of attaching an electronic identification device having an electronic identification means to a vehicle body, which comprises the following steps: a) prior to at least one of the steps painting and galvanizing the body, the identification device is attached to the body by means of a spacer in such a way that the identification device is spaced away from the body; b) following painting and galvanizing, the identification device is permanently arrested on the body without being detached in the meantime from the body. The invention further relates to an electronic identification device for being attached to a vehicle body by means of the method proposed.

Abstract: The invention relates to an electrical high-current connection device comprising a receptacle for an electrical conductor to which conductor the connection device is to be permanently fastened. The device farther comprises an elastic plug contact for being connected with a counterplug. The receptacle and the plug contact are formed of separate parts which are non-detachably fastened to each other.

Abstract: A battery clamp for being connected to a battery contact comprises a connecting lug, a contact ring which is provided with a slot so as to form two opposite clamping ends, and a spring which engages the clamping ends of the contact ring. The battery clamp further comprises a blocking wedge which can be shifted between a contact position in which it releases the clamping ends such that the spring can pull the clamping ends together, a mounting position in which it keeps the clamping ends of the contact ring to be spread apart such that the battery clamp can be placed on the battery contact, and a pull-off position in which it spreads the clamping ends of the contact ring to a larger degree than in the mounting position such that the battery clamp can be pulled off from the battery contact.

Abstract: The invention relates to a cable lug including a receiving section (12) for a cable and an attachment nut (16), wherein a defined contact area having a defined contact force exists between the cable lug (10) and a counter surface to be contacted. To this end, a contact section (14) is provided which is equipped with a bead which by means of the attachment nut (16) can be forced against a counter surface to be contacted.
