Abstract: An assembly for contacting an electrical conductor includes a clamping spring which acts as a pressure spring for fixing an electrical conductor in a spring-force clamp and a retaining spring for locking the clamping spring in an open position such that the conductor can be introduced into a contact region in a shifting direction. The clamping spring touches the retaining spring along a contact surface in a locked state and during movement from the locking state into a unlocking state.

Abstract: A terminal block connecting apparatus includes first and second support members displaceable from a disengaged condition toward an engaged condition in which corresponding main terminal blocks are brought into electrical engagement, characterized by the provision of first and second test terminal blocks connected with the support members for electrical engagement when the first and second support members are in an intermediate condition between the disengaged and engaged conditions. One of the test terminal blocks is supported by a carrier member for movement relative to the associated support member, whereby the test terminal blocks will remain in electrical engagement during displacement of the support members between the test and connected conditions. A friction retaining arrangement serves to resist displacement of the carrier member relative to its associated support member.

Abstract: A connector arrangement includes a housing containing at least one open-topped chamber in which is mounted a stationary upwardly-directed knife device, and a rectangular carrier member arranged for downward insertion within the chamber, thereby to displace an insulated wire supported by the carrier member toward a position in which the knife device pierces the insulation layer and is brought into electrical engagement with the conductor contained therein. The carrier member includes a top surface containing a slot for receiving the tip of an operating tool that displaces the carrier member downwardly in the chamber, and a side wall containing at least one lug and slot arrangement by means of which the carrier member may be upwardly displaced upon lever-like operation of the tool in cooperation with a side wall of the chamber. Preferably, the housing includes a plurality of the chambers arranged in one or more rows.

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.
