A through connector device is disclosed. The device may include a coaxial cable receiver portion defined by one or more surfaces, the coaxial cable receiver portion configured to couple to a center conductor portion of a coaxial cable, the center conductor portion of the coaxial cable protruding above a dielectric material of the coaxial cable. The device may include a beam lead positioned adjacent to the coaxial cable receiver portion. The device may include a planar transmission line contact pad configured to make electrical contact with a planar transmission line of a printed circuit board. The device may include a step configured to electrically and mechanically couple the beam lead to the planar transmission line contact pad, the step configured to create a gap between a bottom surface of the beam lead and a top surface of an outer conductor portion of the coaxial cable.

A surface mount electrical connector and methods of making and using a surface mount electrical connector. The connector includes a housing and a contact subassembly received in the housing. The contact subassembly includes interface contacts, board termination contacts, and an internal circuit board. The interface contacts and the board termination contacts are mounted to the internal circuit board to electrically connect the interface contacts and the board termination contacts through the internal circuit board. Each of surface mount tail ends of the board termination contacts has a bent portion that defines a mounting surface configured to be surface mounted to a mounting face of a main circuit board, to establish an electrical connection between the board termination contacts and the main circuit board.

The present invention provides a contact member that strikes a balance between low electrical resistance and sliding durability. A contact member of the invention has a metal base and a coating disposed on at least part of the metal base. The coating contains fluorinated oil having a polar group, and metal particles surface-treated with a fluorine-based compound having a polar group.

An electrical connector includes multiple conductive terminals respectively retained in multiple accommodating slots of an insulating body. Each conductive terminal includes a base portion, a connecting portion extending from one side of the base portion, a first elastic arm and a second elastic arm extending from the connecting portion toward a direction away from the same one side of the base portion, and at least one fixing portion extending from another side of the base portion. A width of the connecting portion is less than a width of the base portion and less than a width of a location of the first elastic arm near the connecting portion as well as a width of a location of the second elastic arm near the connecting portion. The fixing portion and the first elastic arm are respectively located at different sides of the base portion, thus achieving good elasticity and thinness.

Flexible and low cost power interconnects. The interconnect includes a plug with an insulative support and a plurality of electrical contacts mounted to exterior surfaces of the insulative support. The plug may be simply formed with molding and stamping operations. In use, the plug may be connected in an electrical assembly to support one or multiple power circuits in a compact space. A receptacle for receiving the plug may have an opening with sides bounded by rows of independent electrical contacts that may similarly be connected to one or more power circuits within a printed circuit board to which the receptacle is mounted. The plug and receptacle may be configured such that, when the receptacle connector and plug are each mounted to substrates and the connectors are mated, the substrates are spaced 6 mm, 5 mm, or less.

A preformed solder-in-pin system for use with electrical connectors. The preformed solder-in-pin system generally includes a connector pin having an open cavity at one end, into which a preformed solder member can be first inserted and then pressed, rather than melted, in place, such that voids and air spaces within the cavity are eliminated. The preformed solder-in-pin system can be assembled in high quantities, where the preformed solder members are placed in a fixture and the fixture is placed on a shaker table, so that large numbers of connector pins, pre-installed in connector grommets, can be inserted largely simultaneously.
