Provided is a female electrical connector referred to as a retaining ring terminal. The retaining ring terminal is a one-piece electrical connector having a crimp style cable connector portion on one end for receiving an electrical cable and a female post connector portion on a second end for receiving a post or male electrical connector. The female post connector portion includes a flat planar ring and a plurality of tabs (separated by a plurality of grooves) which extend from the inner surface of the flat planar ring inwardly towards the opening of the female post connector portion. The female post connector portion also includes a groove which extends through a flat planar ring, referred to as a ring groove which becomes a tab groove and has the same shape as the other tab grooves. A pair of ring holes are positioned on opposite sides of the ring groove on the flat planar ring.

The present disclosure provides a wire with terminal that can suppress buckling of a wire during assembly. A wire with terminal includes a wire having a core wire made of a conductor and an insulation coating covering the outer periphery of the core wire, and a terminal connected to a lengthwise end portion of the wire. Also, the wire with terminal includes a reinforcing material adhered to an outer peripheral surface of the insulation coating and an unreinforced part where the reinforcing material is not provided, in the circumferential direction of the wire.

An electrical female terminal for mating with a connector assembly generally including a main body, a two-bodied spring, and a wire fastening portion. A protrusion extends from an unattached end portion of the lever member, the protrusion having faces angled relative to each other to efficiently deflect the lever member upwards when the protrusion interacts with an internal protrusion of a housing or a connector assembly. A top portion of the retainer member of the electrical female terminal, located above the two-bodied spring, has a dimple portion. The terminal face or leading end portion of the electrical female terminal is prevented from damaging or cutting a silicone seal. The overstress feature of the tang member of the lever is improved upon by relocating and reshaping the protruding member thereof. The configuration or shape of the cross-section across the upper portion and the support member at the front end portion of the main body of the electrical female terminal is substantially U-shaped. The configuration or shape of the cross-section across the attached end portion of the lever member of the electrical female terminal is also substantially U-shaped. The electrical female terminal is formed as a continuous and contiguous single construction having included therein at least the main body, the two-bodied spring, and the wire fastening portion and/or the lever member (or tang member), along with the neck member that joins the main body and the wire fastening portion.

An electrical female terminal for mating with a connector assembly generally including a main body, a two-bodied spring, A protrusion extends from an unattached end portion of the lever member, the protrusion having faces angled relative to each other to efficiently deflect the lever member upwards when the protrusion interacts with an internal protrusion of a housing or a connector assembly, which in turn makes the electrical female terminal more difficult to remove from the housing or the connector assembly to thereby protect the electrical female terminal against the electrical female terminal from falling out during use. A top portion of the retainer member of the electrical female terminal, located above the two-bodied spring, has a dimple portion to increase the number of contacts to an upper spring of the two-bodied spring, so as to increase the stiffness of the two-bodied spring. The terminal face or leading end portion of the electrical female terminal is prevented from damaging or cutting a silicone seal, which seals the connector assembly from environmental contaminants, during mating therewith by providing thereon a recessed top face portion and a recessed bottom face portion. The overstress feature of the tang member of the lever is improved upon by relocating and reshaping the protruding member thereof.

A terminal includes a top wall, a side wall, and a curved part connected between the top wall and the side wall. A notch is formed on the curved part. The notch reduces a bending force for forming the curved part and prevent cracks from being generated in the curved part during forming the curved part.

A low insertion force contact terminal which has a conductor mating portion, a securing portion and a substrate mating portion. The conductor mating portion is configured to terminate a conductor therein. The securing portion is configured to secure the terminal in a terminal receiving cavity of a housing. The substrate mating portion extends from the securing portion. The substrate mating portion has at least two sections which have curved portions thereon. The at least two sections move independently, which allows the curved portions to exert a normal force on walls of through holes of a substrate to which the contact terminal is mated which is sufficient to provide a stable electrical connection while allowing for a low insertion force.

An electrical connector includes a main body portion having a receiving passage adapted to receive a plate-type plug inserted in an insertion direction, and a locking protrusion formed on the main body portion and protruding toward the receiving passage. The locking protrusion has a connection portion adapted to connect a top portion of the locking protrusion with the main body portion downstream in the insertion direction.

A male terminal fitting is provided with a base wall extending in a front-rear direction, and a plate-like tab portion extending forward from a front end part of the base wall. The tab portion includes a first wall portion extending forward from the front end part of the base wall, a second wall portion facing the first wall portion, a coupling wall portion coupling side edges on one side, out of both left and right sides, of the first and second wall portions, and a contact wall portion extending from a side edge on the other side, out of the both left and right sides, of the first wall portion toward the second wall portion and abutting on the second wall portion.

A joint connector 10 for electrically connecting a plurality of wires 11 includes a housing 29 and a joint terminal 12 to be disposed in the housing 29. The joint terminal 12 includes a plurality of branch portions 20 arranged along an arrangement direction, a plurality of wire connecting portions 17 respectively continuous with the plurality of branch portions 20 and to be connected to the plurality of wires 11, and a coupling portion 19 for electrically connecting the plurality of branch portions 20 by coupling the plurality of branch portions 20. The coupling portion 19 is in the form of a plate extending in the arrangement direction and is bent. The coupling portion 19 is engaged with the housing 29.

A rubber plug holding structure for a terminal includes an electric wire that has a core wire and an insulating coating which coats the core wire; a rubber plug through which the electric wire is inserted and which seals a gap with the electric wire; and a terminal that has a first press-fastening piece which press-fastens an outer periphery of the rubber plug, in which the terminal has a second press-fastening piece, the second press-fastening piece being formed of a portion of the terminal which remains after cutting a connecting piece serving as a connecting portion of a carrier when the terminal is formed from a chain terminal, and the second press-fastening piece press-fastening a part of the outer periphery of the rubber plug.
