An electrical connector for soldering to a printed circuit board includes an insulative housing, a number of conductive terminals affixed to the insulative housing, and a metal shell surrounding the base portion. The insulative housing includes a base portion. Each conductive terminal includes a soldering portion extending laterally and outwardly from a lateral edge of the base portion. The metal shell includes a pair of longitudinal wall. The electrical connector includes an isolation block isolating the soldering portion from the longitudinal wall of the metal shell in a vertical direction.

A removable device for retaining electrical contacts, having: a rigid element for holding electrical contacts including a plurality of housings that are configured to accept the electrical contacts, the lateral walls of the holding element that are adjacent to the housings having a plurality of openings that each lead into one housing of the plurality of housings of the holding element; and an elastic element for retaining the electrical contacts in the holding element including a plurality of sprung blades that are arranged facing the openings leading into the housings of the rigid holding element so as to retain the electrical contacts in the housings of the holding element. The invention further relates to a soldering method implementing such a device.

A socket comprises a housing made of an insulating board and a plurality of contacts arranged on a first surface of the housing. The housing has a plurality of passageways. Each passageway extends through the housing and has an inner wall surface plated with a conductive material. The housing also has a conductive pad formed on a second surface of the housing so as to correspond to one of the passageways. The conductive pad is electrically continuous with the conductive material of the inner wall surface of the passageway and extends from the passageway. The housing also has a solder ball attached to the conductive pad. Each of the contacts corresponds to one of the plurality of passageways and is electrically connected to both the conductive material of the inner wall surface of the passageway and a contact pad of an electronic component.

A connector lead has a lead terminal that includes a recessed solder wicking restriction area for ensuring that enough solder remains on or near the lead terminal. The lead terminal has a neck portion and a base portion extending from the neck portion. The neck portion has a width that is narrower than the width of the lead. The narrower neck portion defines a recessed solder wicking restriction area that encourages more solder to accumulate on or near the base portion instead of wicking up the lead. The width of the neck portion may also be narrower than the width of the base portion, causing the lead terminal to resemble an inverted T when viewed from the front. A band of solder resistive material may be applied circumferentially or laterally around the connector lead above the lead terminal to limit wicking in some embodiments.

A contact pin for connecting a first electrical conductor made of copper or a copper alloy and a second electrical conductor made of aluminum or an aluminum alloy comprises a plug-in section, a connecting section, and a coating disposed at least on the connecting section. The plug-in section is adapted to couple to the first electrical conductor. The connecting section is adapted to connect to the second electrical conductor. The coating is corrosion-resistant and compatible with aluminum and copper.

To be capable of easily avoiding lengthening and heightening with a simple configuration even in a case where relatively large electric power is supplied. Provided is a configuration in which the conductor resistance of a plurality of contact members 13 and 14 is reduced in accordance with an increment in thickness and energization allowable electric power is increased by one of more of the contact members 13 and 14 being formed thicker than the rest so that an increase in the size of an electric connector such as lengthening and heightening is prevented even in a case where the supply electric power with respect to the electric connector is large and the retention of a flat plate-shaped signal transmission medium F is enhanced by contact portions of the thickness-increased contact members 13 and 14 being pressure-welded to the flat plate-shaped signal transmission medium F.

A sensor element includes: an element body including, for example, a thermistor; paired lead wires drawn out from the element body; and stranded wires that are each obtained by twisting a plurality of core wires and are joined to the respective paired lead wires in a welding region. The welding region includes a main joining region provided in a predetermined region in an axis direction, and sub joining regions adjacent to the main joining region, and joining strength of each of the lead wires and the corresponding stranded wire is higher in the main joining region than in the sub-joining region.

A method to manufacture an electrical connection assembly includes: preparing a wiring material (10) that has conductors and an insulation coating, and preparing a connector (CN) including terminals (20) each having an outward projecting portion (24) with a conductor connection surface (27a) and an insulating housing (30). The method proceeds by setting solder on the conductor connection surfaces (27a) and then removing the insulation coating covering parts to be connected from surfaces of the conductors by melting or dissolving the insulation coating. The method also electrically connects the conductors of the parts to be connected to the conductor connection surfaces (27a) by the solder by heating the parts of the respective conductors to be connected together with the solder while holding a state where the conductors of the wiring material (10) are arrayed at intervals from each other in an array direction.

A welded connection arrangement for cooled current transmission is disclosed. The welded connection arrangement includes a tubular electrical line designed to conduct current from an electrical load, such as a charging socket, to a storage medium, such as a battery. The tubular electrical line includes a first end for connection to the electrical consumer and a second end for connection to the storage medium. The tubular electrical line is furthermore designed to accommodate a coolant for cooling the tubular electrical line. The weld connection arrangement includes an electrically conductive contact part attached to a respective end of the tubular electrical line in order to contact the same electrically. The weld connection arrangement includes a sealing plug inserted into the tubular electrical line at the respective end and, together with the electrically conductive contact part, is welded to the tubular electrical line in order to seal the tubular electrical line against leakage of coolant.

An electrical connector includes a barrel type terminal, having a first connecting area and a second connecting area. The first connecting area has a first non-soldering surface and a first soldering surface. The second connecting area has a second non-soldering surface and a second soldering surface. Each of the first and second soldering surfaces and the first and second non-soldering surfaces has a first solder layer. A sleeve sheathes outside the barrel type terminal, and has a first fixing area and a second fixing area. Two second solder layers are provided between the first fixing area and the first soldering surface and between the second fixing area and the second soldering surface. The amount of solder provided between the first fixing area and the first soldering surface and between the second fixing area and the second soldering surface is greater than that provided on the first and second non-soldering surfaces.
