A plug element (10) includes a housing (10a, 10b) and two contact spring wires (17a, 18a) arranged and fixed in the housing (10a, 10b). The housing (10a, 10b) includes laterally arranged openings (25, 26), and the contact spring wires (17a, 18a) form spring pressure contacts (17a, 18a) in the area of the lateral openings (25, 26).

A connector includes: a housing; and a detector detecting whether a terminal is received at a regular position. The locking portion has an abutment part to lock the terminal, and an interference part interfering with the detector to prevent the detector from being assembled to the housing. The abutment part is displaced to lock the terminal at the regular position when the terminal is at the regular position, and to leave the terminal when the terminal is not at the regular position. The interference part moves along with the abutment part to a position not to interfere with the detector when the terminal is at the regular position, and to be displaced to a position to interfere with the detector when terminal is not at the regular position.

A torsion coil spring supporting structure includes a first supporting portion opposing one end of a torsion coil spring with respect to an axial direction of the torsion coil spring; and a second supporting portion opposing the other end of the torsion coil spring with respect to the axial direction. The first supporting portion includes a spring supporting portion cooperative with the second supporting portion to support the torsion coil spring at a mounting position. The first supporting portion is elastically deformable, by moving the torsion coil spring, to permit the torsion coil to move to the mounting position in a direction crossing the axial direction and elastically restorable to place the spring supporting portion in an inner diameter portion of the torsion coil spring, thus supporting the torsion coil spring at the mounting position.

A terminal (10) of a connector (1) includes a case (20) and a first conductive member (40). The first conductive member (40) includes a junction (43) for connection with a mating terminal. The junction (43) is movable in the compression direction (Y) in which the coil spring (30) is compressed. The case (20) is composed of metal and includes a front wall (22) bent at a front end (21A) of the top wall (21) toward the first conductive member. The front wall (22) is at such a distance from the coil spring (30) that movement of the first conductive member (40) in the compression direction (Y) is not prevented. The front wall (22) includes a support (28) that supports one end (45) of the first conductive member on the front wall side, the one end (45) being movable in the compression direction (Y) at the support when the junction moves.

A connector is provided that has multiple electrode rings which are arranged in a row and capable of allowing multiple wires to pass therein The connector also has a relay ring capable of allowing the multiple wires to pass therein. The relay ring has a first mating part fitted to one electrode ring of two adjacent electrode rings and a second mating part fitted to the other electrode ring.

A terminal module includes an electrical contact having a body (30) configured to face a butting portion (82) on a mating terminal, oriented such that a coil axis (P) is parallel to the body (30) of the electrical contact member and configured to be sandwiched between the mating terminal and the electrical contact (20) to be tilted toward the coil axis (P) when the mating terminal and the electrical contact (20) approach. At least one of a facing surface (31) on the body (30) of the electrical contact (20) on which the obliquely wound coil spring (60) slides and a contact surface (81) on the butting portion (82) of the mating terminal on which the obliquely wound coil spring (60) slides is formed into an uneven surface for increasing frictional resistance during sliding.
