An electrical connector is provided. The electrical connector is connected to the counterpart electrical connector. The electrical connector includes: an insulating housing having an annular portion; a first elastic member provided to the annular portion; and a second elastic member provided to the annular portion, wherein the first elastic member has a first region exposed on an inner surface of the annular portion and configured to contact a first member of the counterpart electrical connector, the second elastic member has a second region exposed on an outer surface of the annular portion and configured to contact a second member of the counterpart electrical connector, and the first elastic member and the first member are electrical contacts and/or the second elastic member and the second member are electrical contacts.

A terminal is provided with a terminal body including a mating connecting portion, a wire connecting portion and a coupling portion, and a shell. The wire connecting portion includes sandwiching portions extending in an extending direction of a wire and configured to sandwich the wire. The shell includes pressurizing portions for pressurizing the sandwiching portions toward the wire. The mating connecting portion includes a mating bottom wall and mating side walls formed to rise upward in a predetermined rising direction from the mating bottom wall. The wire connecting portion includes a wire-side bottom wall and wire-side side walls rising upward in the rising direction from the wire-side bottom wall. The coupling portion is inclined in a direction opposite to the rising direction from the wire-side bottom wall toward the mating bottom wall to couple the wire-side bottom wall and the mating bottom wall.

A socket body (1) having a socket space (3), which is delimited by a socket wall (2) and extends along a central axis (M), for receiving a plug pin, the socket space (3) having a socket opening (6) via which the plug pin can be pushed into the socket space (3), wherein at least one indentation (4), viewed in cross-section transversely to the central axis (M), extends through the socket wall (2) angularly inclined at an angle (a) with respect to the central axis (M) in such a way that at least one spring clip (5) is formed, which spring clip (5) is bent into the socket space (3), and wherein the spring clip (5) has at the front an edge (7) facing the socket space.

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.

A terminal fitting is provided with a tubular connecting portion and a deflectable and deformable resilient contact portion arranged in the connecting portion. The connecting portion includes a bead extending in a front-rear direction and projecting inward toward a contact point of the resilient contact portion on a base wall portion facing the contact point. An outer surface of the base wall portion includes recesses recessed inwardly in both front and rear end parts of the bead, and a shorting terminal facing portion located outwardly of bottoms of the recesses between the both front and rear end parts of the bead.

A contact member includes, an outer conductor including a mating interface section that includes a front end of the outer conductor, a termination section including a rear end of the outer conductor, and a middle section therebetween joining the mating interface and termination sections; an inner conductor received in the mating interface section; and a protective insulator including a main portion received in the mating interface section of the outer conductor and supporting the inner conductor and including an end portion configured for closed entry mating. The end portion has an end face extending outside of the front end of the outer conductor.

A terminal fitting includes a body portion, a first projection, a resilient contact portion and a first fulcrum portion. The body portion is in the form of a rectangular tube open in a front-rear direction. The first projection projects from one wall part toward another wall part, out of two wall parts of the body portion adjacent across one corner. The resilient contact portion is arranged in the body portion. The first fulcrum portion serves as a fulcrum when the resilient contact portion is deflected and deformed. In a developed state of the terminal fitting along the front-rear direction and a width direction, one side end of the resilient contact portion is arranged on one side end part in the width direction. A tip of the first projection is arranged on another side end part in the width direction.

An assembly comprises a cable and a connector. The cable includes at least four direct current (DC) wires. Each of the DC wires has a first coupling portion at an end thereof. The connector is attached to the cable. The connector comprises a housing and two DC contacts. The housing has two accommodating portions. The two DC contacts are arranged in a horizontal direction. The DC contacts are accommodated in the accommodating portions, respectively. Each of the DC contacts has a contact portion and a second coupling portion. The second coupling portion of each of the DC contacts is connected with the first coupling portions of at least two of the DC wires in the corresponding accommodating portion. The first coupling portions, which are connected with the second coupling portion, are arranged in parallel in the horizontal direction.

An elastic contact element of the electrical connector is provided and has an upper ring, a lower ring, and a plurality of elastic flat bodies connected to and located between the upper ring and the lower ring. Each one of the elastic flat bodies is strip-shaped and forms a contact portion. The elastic flat bodies are spaced apart from each other and divided into several groups according to different height positions of the contact portions. Each one of the contact portions protrudes toward a center axis. Because the elastic flat bodies are divided into several groups according to different height positions of the contact portions, the elastic flat bodies contact an inserted male probe at various positions.

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.
