Abstract: A busbar for electrically contacting an electrical conductor has two mutually opposing side walls and a bearing wall for the electrical conductor. The bearing wall extends between the side walls and transversely or substantially transversely to same, wherein the side walls and the bearing wall extend in an insertion direction and define a receiving space for receiving the electrical conductor. At least one electrically conductive projection is provided on one of the side walls and/or the bearing wall. The width of the projection is less than the width of the bearing wall.

Abstract: An electrical plug connection has two main contacts—one plug-in contact and one socket contact configured to mate when the contacts are connected. In the connected state, the contacts contact each other at a main contact point. An auxiliary contact is associated with one of the two main contacts to form an assembly and plug unit. The auxiliary contact is designed as a spring contact which contacts the other main contact in the region of a second contact point. When the two plug-in contacts are disconnected, the auxiliary contact is connected in an electrically non-conductive manner to the main contact with which it is associated. In the mating or connected state where the two main contacts contact each other, the auxiliary contact contacts the other main contact with which it is not associated to form an assembly and plug unit at an auxiliary contact point for measuring the power loss across the plug connection.

Abstract: An electrical power distribution device such as a junction box or the like includes a status indicator that also serves not only to indicate the status of energization of a connector mounted in a first housing opening, but also to illuminate a translucent indicia-bearing plate mounted in second housing opening. The housing contains a chamber in which are mounted a light emitting diode that is energized simultaneously with the connector, and a light transmitting member that directs the light produced by the LED toward the second housing opening.

Abstract: An electrical plug connector arrangement includes a male plug member that is normally locked in engagement with a female socket member by a plurality of radially inwardly directed spring fingers that engage the threads of an externally threaded portion of the plug member, together with an annular quick-release member that is axially displaceable relative to the socket member to release the spring fingers from the threads on the plug member, thereby to permit separation of the plug and socket members.

Abstract: An electrical connector includes a connector body that contains an open-topped chamber in which is mounted a stationary, upwardly-directed insulation-severing electrical contact, together with an operating member for displacing an insulated conductor laterally downwardly in the chamber. The operating member includes a flexible intermediate portion that permits the leading end of the operating member to be introduced initially downwardly into the chamber, and subsequently to be diverted upwardly relative to the connector body by a guide surface arranged at the bottom of the chamber. As the leading and trailing ends of the operating member approach their final positions relative to the connector body, the insulation layer of the conductor is severed by knife edges on the stationary contact, and the conductor is brought into electrical engagement contact with the contact.
