A relay socket mountable on a mounting structure comprises a main body and a clipping system disposed on the main body. The main body has an upper part disposed on a first side of the mounting structure and a lower part extending beyond a fixation edge of the mounting structure to a second side of the mounting structure opposite the first side. The upper part of the main body receives a relay. The clipping system is adapted to lock the main body to the fixation edge.

An electrical terminal device adapted to mount to a structure, and including a electrically non-conductive substructure, an electrically non-conductive cover, a heat resistant shroud, and an electric terminal. The substructure is in contact with the structure. The cover is engaged to the substructure. The substructure and the cover define a chamber, and the substructure defines, at least in-part, a sealed passage in communication with the chamber. The heat resistant shroud substantially covers the cover. The cover is substantially located between the shroud and the substructure. The electric terminal is located in the chamber and is attached to the substructure.

A connector 1 includes a connector housing 50 connectable to a mating connector, female terminals 11 and L-shaped terminals 21 accommodated inside the connector housing 50 and made of a conductive material, and braided wires 31 connecting the female terminals 11 and the L-shaped terminals 21. The braided wire 31 is formed by braiding a plurality of strands 32, 33. The plurality of strands 32, 33 include conductor strands 32 made of a conductive material and high attenuation strands 33 made of a high damping material. The high damping material is a rubber, a resin or a high damping metal. The high damping metal is a damping alloy or a steel material.

A connector-fitting structure of flexible printed circuit includes: a flexible printed circuit on which a wiring pattern is formed; an electronic component connected to the wiring pattern of the flexible printed circuit; and a connector to which one end part of the flexible printed circuit is fitted. The one end part of the flexible printed circuit is fitted to the connector to cause the electronic component to be housed in the connector.

A cable connector including a connector shell including a support and an insert, wherein the insert includes a surface inclined to a cable-to-face direction of the insert so as to re-direct force applied on a face side of the insert sideways toward sides of the connector shell, and the support includes a surface inclined to the cable-to-face direction of the connector shell so as to react to the force, pushing back on the insert, thereby exerting a compression force on the insert. Related apparatus and methods are also described.

A charging gun includes a housing provided with a receiving cavity, a latching member movably assembled at a periphery of the housing, a circuit module mounted in the receiving cavity, and a waterproof and air-permeable assembly. The circuit module includes a magnetic switch. A mounting recess into which the latching member is mounted is provided at the periphery of the housing, and the latching member is rotatable about a rotation shaft in the mounting recess. The latching member is provided with a magnetic element, a state of the magnetic switch is controlled by a change of a relative distance between the magnetic element and the magnetic switch with rotation of the latching member. A mounting hole communicating with the receiving cavity is provided in a bottom surface of the mounting recess. The waterproof and air-permeable assembly is mounted in the mounting hole to discharge heat in the receiving cavity.

A stress cone for reducing electrical stresses is disclosed for use on terminated ends of tubing encapsulated power cable used in surface applications in a subsurface well power system employing electric submersible pumps (ESPs). The stress cone comprises an annular section about a longitudinal axis for receiving a terminated end of the TEPC in its first end and for abutting the terminated metal TEPC end against a metal shoulder at its second end therein, and an insulation chamber axially aligned with and connected to the annular section. The chamber comprises a metal interior surface symmetrical about the axis. The insulated TEPC core (without outer metal sheath) passes through the insulation chamber along the axis and then exits. The ID of the TEPC metal sheath and the inside metal surface of the chamber form a smooth ground plane transition surface. Insulation material surrounds the TEPC insulation layer within the insulation chamber.
