Abstract: One of a pair of connectors (1) of a spring type connector includes an inner housing (3), an outer housing (5), a gap defined between the inner housing and the outer housing, retaining mechanisms (3d, 5c), and a spring (12). The retaining mechanism includes a pair of abutting members (3d, 5c) provided on the inner housing and the outer housing, and a cushioning member (6b) provided between the pair of the abutting members.

Abstract: A connector includes: a first connector which includes a tubular outer housing and an inner housing in which a plurality of first terminals are provided; a second connector which includes a bottomed tubular counterpart housing in which a plurality of second terminals are provided; and an elastic member which is provided in the outer housing and urges the inner housing toward a front side of the first connector in a fitting direction. The inner housing is moved by the elastic member to the front side in the fitting direction at the time of fitting.

Abstract: A locking structure for terminals includes a connector housing in which a plurality of terminal housing chambers accommodating the terminals connected to wires are formed and a first lance and a second lance extending from rear end parts of the terminal housing chambers toward front sides thereof to lock the terminals. A first sidewall of a pair of sidewalls forming a first terminal housing chamber is disposed to face a second sidewall of the pair of the sidewalls forming a second terminal housing chamber adjacent to the first terminal housing with a space between the first sidewall and the second sidewall.

Abstract: A connector has one housing having a tubular body which surrounds terminals; the other housing having a tubular body to be connected to the tubular body of the one housing; and a lock mechanism which allows tip surfaces of the tubular bodies that define external shapes of the pair of housings, respectively, to come into contact with each other and maintains a connected state of the one housing and the other housing.

Abstract: The connector includes an inner housing, an outer housing, a locking mechanism for locking, a spring member that pushes back the inner housing during half fitting, and a pushback regulating position that regulates a pushback position. The pushback regulating portion includes a claw portion, a stepped portion against which the claw portion abuts, and a sliding load portion that makes a sliding friction force between the inner housing and the outer housing at a predetermined timing before abutting to be larger than the sliding friction force before the predetermined timing.

Abstract: In a waterproof structure of a connector (11), each of a pair of housings (17, 19) has an annular member (51, 81) projecting in a fitting direction. An outer circumferential surface (81a) of one annular member (81) is inclined so as to spread outward in the radial direction from the front end toward the back, and presses the inner circumferential surface of the other annular member (51) at the time of fitting. The curvature of the outer circumferential surface of the plurality of corner parts (109a to 109d) of the annular member (81a) is larger than the curvature of the outer circumferential surface of the other portion, and the inclination angle of the former outer circumferential surface with respect to the fitting direction is larger than the inclination angle with respect to the fitting direction of the latter outer circumferential surface.

Abstract: One of a pair of first terminals includes a spring member of which one end is supported by the first housing. A contact portion that contacts one of a pair of second terminals is formed on a free end of the spring member. A lock arm abuts against the spring member to displace the contact portion, and brings the contact portion into contact with one of the second terminals at the time of locking. The other of the first terminals has a contact portion that contacts the other of the second terminals when the connectors are fitted, and is disposed apart from one of the first terminals.

Abstract: A connector includes a pair of housings to be fitted to each other by inserting an insertion part of one housing into a tubular part of another housing. On an outer peripheral surface of the insertion part of the one housing, a plurality of outer ribs which project from the outer peripheral surface are provided separately in a circumferential direction to extend from a front end of the insertion part to a rear side. On an inner peripheral surface of the tubular part of the other housing, a plurality of inner ribs which project from the inner peripheral surface are provided separately in a circumferential direction to extend from a front end of the tubular part to a rear side. The outer ribs and the inner ribs are provided such that positions in the circumferential direction are deviated from each other.

The inner housing is moved by the elastic member to the front side in the fitting direction at the time of fitting.

Abstract: There is provided a waterproof connector structure which includes a pair of connector housings. An opening end portion of a cylindrical body of one connector housing is inserted into an opening end portion of a cylindrical body of another connector housing at the time of fitting. One cylindrical body has a projection part which is provided to protrude outward in a radial direction from the opening end portion thereof entirely in a circumferential direction. The projection part is provided on a front side in a fitting direction from an opening part of a terminal receiving chamber surrounded by the one cylindrical body.

Abstract: One of a pair of first terminals includes a spring member of which one end is supported by the first housing. A contact portion that contacts one of a pair of second terminals is formed on a free end of the spring member. A lock arm abuts against the spring member to displace the contact portion, and brings the contact portion into contact with one of the second terminals at the time of locking. The other of the first terminals has a contact portion that contacts the other of the second terminals when the connectors are fitted, and is disposed apart from one of the first terminals.
