The special-shaped joint has a simple structure and is easy to assemble. An included angle between the connection terminal and the core is greater than 0 degree and smaller than 180 degrees, so that the special-shaped joint can be applied to an electrical device with a specific connection requirement for the included angle between the connection terminal and the wire, thus having a wide application range.

A solder sleeve for connecting a wire to another wire or to a terminal device is formed from an alloy comprised of 42 percent tin and 58 percent bismuth that has a eutectic melt point of approximately 138° C. The wire receiving portion, at least one side of the solder sleeve is in the form of a hollow tubular member that is extruded so as to lack a longitudinal seam, the opposing side may be in one of many forms. A thermochromic dye is mixed in with a flux layer located on a portion of the outer surface of the solder sleeve, the dye designed to change from a first color to a second color at the same temperature as the melting point of the alloy. The solder sleeve may be held within a heat shrink tube.

An electrical connector assembly includes a connector housing defining a cavity and an opening providing access to the cavity, first and second direct current (DC) terminals disposed within the cavity, and first and second busbars electrically and mechanically attached directly to the first and second DC terminals respectively. The first and second busbars each have a rectangular cross section and wherein the first and second busbars extend through the opening such that portions of the first and second busbars are outside of the connector housing. A method of manufacturing an electrical connector assembly is also provided.

A soldering aid for connecting a cable to a printed circuit board includes an electrically insulating body having a first, second and third recesses, and an electrically conductive contact structure coupled thereto. The contact structure is partially embedded in the body to be connected to a cable core therein, and partially protrudes from the body to be connected the printed circuit board. The first recess is conically tapered to receive an end portion of the cable and has first and second sections for non-stripped and stripped portions of the cable end portion, respectively. An end of the second recess adjoins the second section of the first recess to enable optical verification of formation of a connection between the cable core and the contact structure. The third recess is configured to receive and transfer solder to the second section of the first recess to thereby form the connection.

A cable connector includes a contact module, wires and grounding bars. The contact module includes a pair of subunits commonly sandwiching a metallic shielding plate. Each subunit includes contacts integrally formed within an insulator, the contacts includes a plurality of differential-pair contacts and grounding contacts alternately arranged with each other. Each contact includes a front contacting section and a rear tail section, the tail sections of the grounding contacts being unified with a transverse bar. Each wire has a pair of inner conductors respectively soldered to the tail sections of the corresponding differential-pair contacts, and an outer braiding layer surrounding the pair of inner conductors and mechanically and electrically connected to the transverse bar. Each grounding bar includes a plurality of rear tabs respectively connected to the braiding layers, and a plurality of front tabs respectively connected to the tail sections of the corresponding grounding contacts.

A soldering aid for electrically conductively connecting a cable core of a cable to a conductor area includes a body made of an electrically insulating material and an electrically conductive contact part received in the body. The contact part has a contact surface configured to electrically conductively contact the conductor area. The body is formed with a receptacle having a slot open toward one side configured to receive the cable core of the cable, and is formed with a through-bore configured to surround a sheathed portion of the cable. The contact part closes an opening at a bottom of the slot and conductively contacts the cable core.

An output wire joining structure of a winding seat for a transformer or an inductor is disclosed. The winding seat includes a winding portion and a support portion. The winding portion is disposed on top of the support portion for winding a coil. Two sides of the support portion are provided with pin holders for insertion of output wires of the coil. At least one joining plate is disposed beneath the pin holders corresponding in position to the output wires. The output wires of the coil and metal pins of the pin holders are soldered to the joining plate respectively, so that the output wires and the metal pins are quickly soldered and fixed to form a connection, which has the advantages of increasing the rated current and facilitating the operation.

A connector 1 includes a connector housing 11, a thin wire coaxial cable 17 for providing a coaxial connection between an external coaxial cable 2 and a circuit board provided in a separated housing and a shield member 12 which is provided in an inner space of the connector housing 11 and electrically connected to a shell 173 of the thin wire coaxial cable 17. The shield member 12 has a holding mechanism for holding the thin wire coaxial cable 17.

A modular electrical connector facilitates low loss connections to components on a printed circuit board. A portion is of the connector is formed of one or more first type units with conductive elements designed to be attached to a printed circuit board. Signals passing through those units may be routed to components on the printed circuit board through traces in the board. One or more second type units may be integrated with the connector. Those units may be designed for attachment to a cable, which may provide signal paths to a location on the printed circuit board near relatively distant components.
