A strand protective plate for clamping a strand of an electric cable in a strand clamping body by means of a clamping screw which acts on the strand protective plate and is screwed into the strand clamping body, wherein the strand protective plate has a strand clamping tongue for bearing against the strand and a bent-over region and a contact region for bearing against the strand clamping body. The strand clamping tongue is connected by means of the bent-over region to the contact region, and a leadthrough opening for guiding the clamping screw through is arranged in the contact region. At least one clamping jaw fixedly clamps the damping screw which is guided through the leadthrough opening is configured on the contact region adjacently with respect to the leadthrough opening.

A meter socket is provided for watt-hour meters. The meter socket comprises a block assembly mounted at a center of the meter socket, a bypass mechanism situated in the bottom portion of the block assembly and a plurality of clamp jaws. The block assembly includes a top portion and a bottom portion. The bypass mechanism includes a plurality of rotary bypass blades coupled to a lever arm. Each clamp jaw includes a clamp jaw assembly that includes a jigsaw mechanism situated in the top portion of the block assembly. The jigsaw mechanism includes a copper jaw bus, a contact plate, a jaw spring, a bypass spring, a compression spring, a shoulder screw, a rivet or one or more fasteners. Each clamp jaw further includes a clamp jaw bypass mechanism that includes a jaw opening formed between the copper jaw bus and the jaw spring to receive a rotary bypass blade of the plurality of rotary bypass blades of the bypass mechanism.

A conductive component structure for wire connection terminal has higher electro-conductive performance and is more securely assembled with the conductive wire. The conductive component includes a main body in the form of a plate body and a restriction body connected on the main body. The restriction body has a base section, a bow section connected with the base section and a free section connected with the bow section, which together provide elastic effect for the restriction body. When the conductive wire is plugged in to contact the conductive component, the restriction body guides the conductive wire and the rear end of the conductive wire is securely pressed and restricted between the main body and the restriction body.

A wire clip electrical connector, comprising a connector body, an elastic clip piece and an elastic conductive piece disposed in the connector body, and a push rod slidingly matched with the connector body. A wire insertion hole is formed in the connector body, and an elastic clip piece and an elastic conductive piece are located on two sides of the wire insertion hole, and the push rod is provided with a spring piece pressing structure and a stopping structure. According to the above design, the wire is inserted into the wire insertion hole, and the push rod slides relative to the connector body, and the elastic pressing structure on the elastic bar acts on the wire elastic piece, and the wire elastic piece presses the wire on the elastic conductive piece, and the stopping structure restricts the decoupling to achieve a stable connection between the electrical connector and the wire.

An electrical contact system includes a contact having a barrel with a wire entry portion having a first diameter, a clip portion having a second diameter, and a cam portion having a second diameter at a first end that tapers to a third diameter at a second end near the wire entry portion. The system also includes a clip positioned in the clip portion of the barrel, wherein ends of inwardly directed tines of the clip are configured to engage the conductor to enable the clip to be drawn onto the cam portion in response to a user pulling the wire after insertion of the conductor through the clip.

An insulation body for an electrical connector unit includes at least two insertion channels into each of which a contact pin or a contact bush can be inserted, which preferably are aligned parallel to a main axis of the insulating body into which a securing channel empties, preferably perpendicular to it, in which a set screw is supported so as to turn, by means of which the related contact pin or the related contact bush can be mechanically impinged on, and to which an insulating collar is assigned, which is arranged on the outer side of the insulating body, at least approximately coaxial to the related securing channel. Preferably each of the insulating collars has at least one collar opening that is limited on both sides by collar ends.
