Herein is described a n electrical earthing device formed from a sheet of material and comprising: an earthing device connector portion, for connection of the earthing device to a component to be earthed; and an earth cable connector portion, for connection to an earth cable. A first part of the earth cable connector portion is disposed in relation to a second part of the earth cable connector portion so as to define a clamping mechanism. In use, an earth cable positioned between the first and second parts is retained in position and maintained in electrical contact with the clamping mechanism by resilient biasing between the first and second parts of the clamping mechanism.

An electrical plug connector having a housing and a contact carrier held inside the housing. It comprises an electrically insulating base part and at least one pair of first electrical contacts for transmitting energy and multiple pairs of second electrical contacts for transmitting data. The contacts are held in the base part and arranged so as to be distributed in a plane extending essentially perpendicular relative to the longitudinal axis of the contact elements and the contact carrier. First distance lines between the contacts of the pairs of first contacts are free of overlaps with second distance lines between the contacts of the pairs of second contacts.

A power connector socket includes a main body and a lamella cage. The main body includes a socket, an opening at a side portion of the socket, and a chamber inside the socket. The lamella cage passes through the socket. The lamella cage includes a ring portion and contact lamellae. The contact lamellae outwardly extend from a side portion of the ring portion and are annularly arranged. The ring portion is in an inner side of the chamber. One of two ends of each of the contact lamellae includes a fixed end formed on the ring portion, a free end outwardly extends from the other end of each of the contact lamellae, and the free ends are positioned at a portion of the main body adjacent to the opening.

A relay includes a housing, a fixed terminal, a screw receiving member, and at least one female screw member. The fixed terminal has a plate shape. The fixed terminal includes a fastening portion having at least one screw insertion hole. The fastening portion is exposed from the housing to an outside and is screwed to an external terminal. The screw receiving member overlaps with the fastening portion in a penetrating direction of the at least one screw insertion hole and is provided in proximity to the fastening portion. The at least one female screw member is provided integrally with or separately from the screw receiving member and is prevented from rotating by the screw receiving member.

A meter box ground clamp may include a body portion having a first portion, a second portion, and a gripping portion that is configured to extend from the second portion and a fastener member configured to couple the body portion to an electrical meter box. The fastening member may be configured to extend through a receiving portion of the first portion to engage a first surface of the meter box so as to move the first portion away from the first surface of the meter box and move the gripping portion into engagement with a second surface of the meter box that faces away from the first surface of the meter box, and the receiving portion may be configured to receive the fastener member at a first angle less than 90 degrees relative to a plane of the first portion such that a free end of the fastener member forms a second angle greater than zero degrees relative to the second surface of the meter box. The second angle may be configured to create a force that urges the second portion of the body portion toward the meter box in response to a tightening torque applied to the fastener member so as to prevent the body portion from moving off the meter box in response to the tightening torque.

Herein is provided a connector for providing an electrical connection between a conducting element and a connecting point, the connector comprising a first portion, a contacting element and second portion, the first portion being configured to be reversibly fastened to the second portion to thereby fasten a conducting element by the contacting element between the first portion and second portion.

Wedge type electrical connector assemblies adapted to electrically and mechanically connect conductors within transmission and/or distribution circuits is provided. The wedge type electrical connector assembly includes a frame, an interface and a wedge assembly. The interface is coupled to the frame so that it is movable relative to the frame. The interface can move and flex when installing conductors into the wedge type electrical connector assemblies.
