Abstract: It is aimed to provide a female terminal of a novel structure having a large degree of freedom in setting a pressure contact force between a male terminal including a columnar connecting portion and a female terminal including a tubular connecting portion and capable of stably ensuring a large contact area between the male and female terminals. A female terminal 10 includes a tubular connecting portion 24 having a first peripheral wall portion 12 and a second peripheral wall portion 14 arranged to face each other and to be conductively connected to a cylindrical connecting portion 22 of a male terminal 20, a biasing means 64 for biasing the first and second peripheral wall portions 12, 14 in directions approaching each other, and an arcuate protrusion 34 provided on an inner surface 18 having an arcuate cross-section of at least one of the first and second peripheral wall portions 12, 14 and projecting radially inward while extending in a circumferential direction of the inner surface 18.

Abstract: A large-current terminal (30) includes a male terminal (50) having a male-side contact surface (54), a female terminal (60) having a female-side contact surface (64), a coil spring (70) including male-side contacts (72) for contacting the male-side contact surface (54) and female-side contacts (71) for contacting the female-side contact surface (64). A spring holder (40) holds the coils spring (70) and includes male-side and female-side openings (44, 45) for exposing the male-side and female-side contacts (72, 71). The coil spring (70) is compressed in a facing direction of the contact surfaces (54, 64) by disposing the male-side contact surface (54) to face both the female-side contact surface (64) and the male-side openings (44) with the female-side contact surface (64) directed toward the female-side openings (45). The spring holder (40) is movable such that the female-side opening (45) approaches the female-side contact surface (64) as the coil spring (70) is compressed.

Abstract: 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.

Abstract: A connector (C) includes a flat terminal (20), an obliquely wound coil spring (10) wound around a winding axis (A) that is parallel to the terminal (20) with the coil spring (10) sandwiched between the terminal (20) and a flat mating terminal (71). A connector housing (30) accommodates the terminal (20) and the coil spring (10) and includes an insertion path (37) for the mating terminal (71) to be parallel to the terminal (20). A rotation restricting portion (33) is in the connector housing (30) and restricts the coil spring (10) in a rotation posture to tilt with respect to the winding axis (A) such that a mating terminal side of a half-turn winding plane and a straight line connecting a start point (P1) and an end point (P2) of the half turn is on a back side in an inserting direction of the mating terminal (71).

Abstract: A terminal fitting includes an electric contact member (20) which has a facing surface (21) facing a contact surface (81) disposed on a counterpart terminal (80) and is connected to an external circuit. An obliquely wound coil spring (40) has an electroconductive wire member (41) wound a plurality of times so that the winding surface is oblique with respect to a coil axis L. Both ends of the electroconductive wire member (41) are fixed to the electric contact member (20) in such an attitude that the coil axis L is parallel to the facing surface (21) of the electric contact member (20), and the obliquely wound coil spring (40) is to be sandwiched between the counterpart terminal (80) and the electric contact member (20) when the counterpart terminal (80) and the electric contact member (20) come close to each other.
