An installation switching device has a housing and screw connecting clamp with an essentially frame-shaped clamping part having longitudinal faces, narrow faces and broad faces, a head-clamp screw received in a clamping part threaded aperture, and a current rail arranged fixed in the device extending through the frame-shaped clamping part interior, wherein a current rail broad face is oriented, as assembled, parallel to a clamping part broad face facing the head clamping screw, the screw supporting itself, screwed in, on the current rail, wherein consequently, the clamping part is displaceable in its longitudinal direction, parallel to the narrow face, relative to the current rail by further screwing in the head clamping screw so a connecting conductor can be fixedly clamped between the current rail face remote from the screw and the clamping part broad face remote from the screw, the housing having a screw receiving region guiding the screw head.

A ground block may include a metal ground plate and a ground wire fixedly coupled with the metal ground plate. The ground wire is configured to be non-detachable from the ground block during normal use of the ground block. The ground block may be formed by soldering, brazing, or clamping the ground wire to the metal ground plate.

The invention relates to a method for producing a nut which is rotationally connected to a flat part connecting section of a cable shoe, wherein the flat part connecting section has a passage opening, the nut has a sitting face which is at the bottom in the connected state, and a holder section extends on the nut from the sitting face further downward, wherein a tapered portion of the passage opening is formed by a holder material section which is preliminarily curved into the passage opening by deformation, and the holder material section is produced by a recess which is made in the flat part connecting section so as to surround the passage opening on a top side of the flat part connection section, which top side is associated with the sitting face. In order to specify a method of this kind which can be carried out in respect of production, in particular in respect of the production costs, in a favourable manner, it is proposed that the holder material section is first formed and the nut is placed onto the top side, wherein the holder section protrudes downward beyond a narrowest cross section of the passage opening which is formed by the holder material section, and that the holder section is then widened below the narrowest cross section, for the purpose of holding the nut on the cable shoe in a rotatable and interlocking manner. The invention further relates to a nut which is fitted in a rotatable manner on a flat part connecting section of a cable shoe.

A connection arrangement of a first component on a second component, in particular for a vehicle, is provided, wherein the components are connected together by at least one screw element and at least one screw which is screwed into the screw element and passes through a first passage opening of the first component. The screw element is designed as an expansion sleeve which is partly received in a second opening of the second component and protrudes into the first component and which is expanded along the axial direction of the sleeve by screwing the screw into the expansion sleeve.

A circular plug-in connector for establishing a shielded plug-in connection to a mating plug-in connector includes: a contact carrier having at least one electrical contact element; a shielding sleeve that surrounds the contact carrier at least in part; and a screw housing that is rotatably connected to the shielding sleeve and adapted to screw the circular plug-in connector to the mating plug-in connector. A connection portion of the shielding sleeve is received in a receiving space of the screw housing The circular plug-in connector provides shielded contact between the screw housing and the shielding sleeve. The shielding sleeve includes a collar in the connection portion. The circular plug-in connector further includes a stopper for closing a receiving opening of the receiving space at least in part, such that the collar is trapped in the receiving space.

An electrical connector is configured to couple an electrical conductor to a support surface. The electrical connector includes a terminal block having a connecting aperture and a threaded aperture. The connecting aperture is configured to receive the electrical conductor. The electrical connector also includes a fastener having threads receivable within the threaded aperture. The fastener is configured to secure the electrical conductor against movement relative to the terminal block. The electrical connector further includes a lock selectively receivable within a slot of the fastener to inhibit unintentional movement of the fastener relative to the terminal block.

An electrical connector assembly is provided with a conductive body with a first aperture formed therein, and a second aperture formed therein intersecting the first aperture. A first post has an aperture formed radially therethrough. The first post is sized to be received within the first aperture of the conductive body with an end of the first post accessible externally from the conductive body for receipt of a first electrical connector. A fastener is sized to be received within the second aperture of the conductive body and extend through the aperture in the first post to retain the first post in the conductive body for electrical communication between the first electrical connector and the conductive body. A second post is exposed externally from the conductive body for receipt of a second electrical connector for electrical communication with the first electrical connector.

An electrical connector is configured to couple an electrical conductor to a support surface of an electrical device. The electrical connector includes a terminal block having a connecting aperture and a threaded aperture. The connecting aperture is configured to receive the electrical conductor. The electrical connector also includes a fastener having threads receivable within the threaded aperture. The fastener is configured to move in a first rotational direction relative to the threaded aperture. The electrical connector further includes a lock configured to be positioned between the electrical conductor and the fastener to engage the electrical conductor and the fastener. Rotation of the fastener in the first rotational direction causes the lock to secure the electrical conductor against movement relative to the terminal block.

An integrated locking and sealing fastener with electrical conductivity is revealed. The integrated locking and sealing fastener with electrical conductivity includes a fastener with a surface and a conductive anti-loosening coating. A part of the surface of the fastener is a fastening contact surface and the conductive anti-loosening coating is formed on the fastening contact surface. The conductive anti-loosening coating consists of an anti-loosening portion and a conductive portion mixed with each other. The anti-loosening portion is made from polyamide (PA) resin, acrylic (PMMA) resin, polyethylene, epoxy resin, silicone, rubber, or the combinations. The conductive portion is made from materials including carbon black, metal powders, a silver wire, graphite, or the combinations. The coating on the fastener not only prevents loosening and leakage but also provides electrical conductivity.
