A pressing element is configured for an electrical component which needs to be pressed against another element for contact. The electrical component includes at least one electrically conductive touch contact. The pressing element has an annular pressing surface for the electrical component. An outer contour of the pressing surface is greater than an outer contour of the electrical component which needs to be pressed. The pressing surface has an annular elevation which forms a bearing surface for the electrical component.

An electrical power wet-mate assembly includes a compliant-insulated pin assembly and a ceramic-insulated pin assembly. Those pin assemblies are physically and electrically engaged to one another. The compliant-insulating material may be a thermoplastic, and the ceramic-insulating material may be alumina. The electrical power wet-mateable assembly may be used in conjunction with a pressure containing device such as a subsea tree to form a wet-mateable connection system. The electrical power wet-mate assembly is capable of operating in high pressure differential and high temperature environments. A plurality of ceramic-insulated pin assemblies may be welded to a connector body to form a pressure barrier system. The cavities created by the ceramic-insulated pin assemblies and the compliant-insulated pin assemblies may be filled with a dielectric oil. Individual pressure compensators may be dispersed equally between the pin assemblies.

A penetrator device has an outer housing of non-conductive, insulating material having a through bore, at least one conductive pin formed in one or two parts extending through the housing and having a first end portion and a second end portion extending out of the respective first and second ends of the housing, a first cladding layer bonded over the first end portion of the pin to form a first bonded assembly, a second cladding layer bonded over the second end portion of the pin to form a second bonded assembly, and the material of the first and second cladding layer comprising a corrosion resistant conductive material different from the pin material.

A braided part connection structure includes a braided part having a tubular shape covering an insulated wire along a longitudinal direction of the braided part connection structure and a shield member having a tubular shape and electrically connected and fixed to the braided part. The shield member includes a braided part joining portion having a plurality of openings arranged at intervals along a circumferential direction of the shield member in a portion of the shield member in the longitudinal direction, and a welding portion defined by two openings adjacent to each other of the plurality of openings. The braided part covers the braided part joining portion and is welded to the welding portion.

An electrical connector for connecting a bus bar to a flexible conductor comprising a tubular conducting body having a first end adapted for lockably receiving an end of the flexible conductor and an opposite second end adapted for mounting a corresponding end of the bus bar therewith. The electrical connector is also provided with at least one resilient element operatively mounted with the second end of the tubular body and the corresponding end of the bus bar for maintaining the bus bar and the tubular body connected together.

A novel end aluminum part including a first cylinder (1) for accommodating a conductor (7) of an aluminum wire (5), a second cylinder (2) for abutting an insulation layer (6) of the aluminum wire (5), and a third cylinder (3) for accommodating the aluminum wire (5). The first cylinder (1) is connected to the top of the second cylinder (2), and the third cylinder (3) is connected to the bottom of the second cylinder (2). An inner diameter of the bottom of the second cylinder (2) is larger than an inner diameter of the top of the second cylinder (2), an inner diameter of the first cylinder (1) is the same as the inner diameter of the top of the second cylinder (2), and an inner diameter of the third cylinder (3) is the same as the inner diameter of the bottom of the second cylinder (2). The second cylinder (2) will not only reduce the stress between the insulation layer and the end aluminum part, so as to reduce the possibility of cracking or breakage of the end aluminum part due to excessive concentration of stress during crimping with the aluminum wire, but also prevent the insulation layer from being pressed into the conductor

An evaluation jig comprises a female terminal connectable to a male terminal of a charging connector. The female terminal includes a plurality of contact pieces and a support portion. Each contact piece has a flexible piece, and a contact portion protruding toward the center axis from an inner surface of the flexible piece. The flexible piece forms a portion of a cylinder having the center axis. The flexible piece has a length equal to or larger than twice an outer diameter of the cylinder in a direction parallel to the center axis. The flexible piece is elastically deformable so that the flexible piece has a distal end portion to be displaceable in a radial direction of the cylinder relative to a proximal end portion of the flexible piece. The contact portion has a shape curved so as to protrude inward in the radial direction.
