A fastener used to secure an electrical conductor includes a head, a shaft, and a pressure pad. The head has an inner surface for receiving a drive tool. The shaft has an outer surface including a threaded portion. The pressure pad can include a surface feature. The pressure pad can also be releasably, rotationally-fixed to the shaft through a breakaway portion.

A wire clamp connector includes a connecting board, a plurality of conductive sheets, a plurality of conductive mounts, and a plurality of wire clamp components. The conductive sheets are disposed at one surface of the connecting board. The conductive mounts are disposed at the top of the connecting board and connected to the conductive sheets. The wire clamp components are disposed at the respective conductive mounts. Each of the wire clamp components includes a lock member and a clamping piece. The lock member pushes the clamping piece to push against a wire, so that the wire can be firmly positioned with the corresponding conductive mount. Furthermore, the wire clamp connector may be applied to the wall mount component so as to be mounted on a wall and connected to an electronic product.

An electrical transmission line repair device including a first conductor clamp, a second conductor clamp and at least one tie rail extending between the first and second conductor clamps in a spaced apart orientation. The first conductor clamp including a lower assembly and an upper assembly. The lower assembly and the upper assembly are slidably engageable with each other so as to define a conductor cavity extending therealong. Clamping fasteners are configured to extend through openings in the upper assembly so as to be threadable toward and away from the conductor contact region of the lower assembly within the conductor cavity.

An electrical connector includes a clamp body having a base, a side portion, and an upper portion. The clamp body defines a cable groove having an arched configuration configured to receive a primary conductor and an aperture for receiving a secondary conductor. A primary fastener is movably connected to the clamp body. A keeper is connected to the clamp body and moveable with the primary fastener to secure the primary conductor in the cable groove. A secondary fastener is configured to receive the secondary conductor in the aperture.

A wiring structure includes: a housing; a wiring frame, movably arranged in the housing in an up-and-down direction; a wiring board, extending into the wiring frame from a first side perpendicular to the up-and-down direction, the wiring board being fixed relative to the housing; a bolt, penetrating through a top plate of the wiring frame and configured to drive the wiring frame to move upward through a downward rotary movement; an external wire, extending into the wiring frame from a second side opposite to the first side; and a flexible pressing piece, arranged between a bottom plate of the wiring frame and the wiring board, and abutting against the external wire and subjected to a downward pressure of the external wire upon the wiring frame moving upward, exerting an upward biasing force on the external wire and pressing the external wire between the wiring board and the flexible pressing piece.

An electrical connector includes a clamp body having a base, a side portion, and an upper portion. The clamp body defines a cable groove configured to receive a primary conductor and an aperture for receiving a secondary conductor. A primary fastener is movably connected to the clamp body. The primary fastener has a first section and second section telescopically connected to the first section. A keeper is connected to the clamp body and moveable with the primary fastener to secure the primary conductor in the cable groove. A secondary fastener is configured to receive the secondary conductor in the aperture.

An electrical connector includes a clamp body having a base, a side portion, an upper portion, and a boss. The clamp body defines a cable groove configured to receive a primary conductor and an aperture for receiving a secondary conductor. A primary fastener is movably connected to the clamp body. A keeper is connected to the clamp body and moveable with the primary fastener to secure the primary conductor in the cable groove. A secondary fastener is configured to secure the secondary conductor in the aperture. The clamp body is configured to provide a spring force to the secondary conductor when engaged with the secondary fastener.
