A device for receiving a data carrier has a receiving body that has a receiving region with a circular-cylindrical cross-section, wherein the receiving region has a circular opening on one end of the receiving body that corresponds to the cross-section of the receiving region, a data carrier which is arranged at least partially in the receiving region, and a circular-cylindrical fixing pin that is arranged on the other end of the receiving body.

An electrical connector comprises an insulating body, a pair of first terminal members, a pair of second terminal members, and a fastening part. The insulating body comprises a mating groove. The pair of first terminal members is disposed in the mating groove. Each of the first terminal members comprises a plurality of first elastic contacting parts. The pair of second terminal members is disposed in the mating groove. The pair of first terminal members is disposed between the pair of second terminal members. Each of the second terminal members comprises a plurality of second elastic contacting parts. The second elastic contacting part abuts against the first elastic contacting portion correspondingly. The fastening part fastens the pair of first terminal members and the pair of second terminal members.

An electrical contact element for electrically contacting a mating contact element includes: a plurality of contact lamellae which are arranged around a plug opening into which a mating contact element is pluggable along a plug direction and which together form a groove that encircles the contact lamellae around the plug direction; and a spring element that is arranged on the groove and engages the contact lamellae to provide an elastic clamping force on the contact lamellae. The contact lamellae each have an inner surface which faces the plug opening and is straight in cross section transversely to the plug direction.

A grounding system for a rackable circuit breaker includes a finger cluster connector connected to a grounding bus in the circuit breaker and a rail conductor mounted in a circuit breaker cradle and connected to ground potential. The finger cluster connector includes a conductor formed from a single plate of conductive material folded into a generally U-shaped body with first and second sides divided into a plurality of fingers. Distal ends of the fingers form mutually facing parallel surfaces of a constricted passage configured to make a sliding electrical contact with the rail conductor that is advanced into the constricted passage as the circuit breaker is racked into the cradle. First and second leaf springs fastened to the conductor portion are divided into a plurality of spring finger sections with spring distal ends configured to respectively press against the distal ends of respective fingers of the conductor portion.

A connector assembly is provided for facilitating live connection of equipment in a switchgear. The assembly includes two circular plates, and conductive fingers which are arranged and spaced apart around the two plates to form a finger cluster with first open-end on a first cluster end and second open-end on an opposite second cluster end. Each open-end can receive a conductor therein. Each finger can include a first finger end and an opposite second finger end which form respective first and second cluster ends; two first interior grooves which are spaced-apart on an interior surface to receive a portion of respective plates; and first and second exterior grooves on an exterior surface around the first and second finger ends respectively. The assembly also includes first and second garter springs which are arranged around the fingers in respective first and second exterior grooves to apply a force against the fingers.

A spring-actuated electrical connector assembly for electrically and mechanically connecting a device to a power source in high-power, high-voltage applications is disclosed. The connector assembly includes a first connector with an internal receiver, a plurality of side walls, and at least one contact beam. The contact beam integrally extends to an outer surface of the side wall and includes a free end that extends inward of the outer surface of the side wall. An internal spring member is dimensioned to reside within the receiver of the first connector. This assembly also includes a second electrically conductive connector with a receptacle dimensioned to receive both the first connector and the spring member to define a connected position during operation of the device. In the connected position, at least one spring arm of the spring member exerts an outwardly directed force on the contact beam of the first connector to outwardly displace the contact beam into engagement with the second connector.
