Abstract: A connection terminal includes a tubular electrical connection portion into which a mating connection portion of a mating terminal is inserted. The electrical connection portion is provided with an elastic piece with a first contact portion and an opposing wall disposed opposite to the elastic piece. The opposing wall includes: second contact portions disposed on a front side and a rear side in an insertion direction of the mating connection portion, and projecting toward an elastic piece side; and a curved surface located between the second contact portions and curved so as to be separated from the mating connection portion. The curved surface includes a first curved surface located on the rear side in the insertion direction and a second curved surface located on the front side in the insertion direction. A curvature of the second curved surface is set larger than a curvature of the first curved surface.

Abstract: A connector includes: a first connector including a first main terminal; a second connector including a second main terminal and a boss having a protruding shape; and a fitting detection circuit configured to detect fitting of the first connector and the second connector. The first connector further includes a rotatable lever used for a fitting operation to the second connector and a fitting disengagement operation from the second connector. The lever includes a lock configured to lock, when the lock contacts the boss in the fitting disengagement operation, a rotation of the lever in a state where the fitting is not detected by the fitting detection circuit and also in a state where the first main terminal and the second main terminal are connected.

Abstract: A lever-type connector includes a first housing and a second housing which are capable of being fitted to each other; and a lever mounted on the second housing. The first housing includes a first terminal storage chamber capable of storing a first terminal therein, and a cam boss which moves together with the first housing in a fitting direction when the first housing and the second housing are fitted to each other. The second housing includes a second terminal storage chamber capable of storing a second terminal therein. The lever includes a cam groove capable of receiving the cam boss. The lever approximates the first housing and the second housing to each other and brings the first terminal and the second terminal into press contact with each other while moving the cam boss along the cam groove.

Abstract: A lever connector includes a lever which includes a lever-side lock part configured to be elastically deformed in a first direction to be separated from a surface of a second housing and configured to be locked to a housing-side lock part of the second housing when the lever is in a fitting start position. A first housing includes a pressing part configured to move together with the first housing in a fitting direction at a time of fitting, and configured to release a lock between the lever-side lock part and the housing-side lock part by pressing the lever-side lock part in the first direction. The second housing includes a lap part configured to be brought into close contact with an edge part of the lever when the lever is in a fitting completion position, so as to prevent that the edge part is deformed in the first direction.

Abstract: A connector housing mounting structure includes a connector housing; and a mounting member having a mounting surface. The connector housing includes a housing body, and a pair of flange portions extending from the housing body and having first mounting holes respectively. The mounting member includes a pair of first columnar portions protruding in parallel with each other from the mounting surface. Each of the first columnar portions is inserted into each of the first mounting holes, and the pair of flange portions is fixed to the mounting surface, thus the connector housing is regularly mounted on the mounting surface. A size of one of the flange portions in a width direction perpendicular to an extending direction of the flange portion is larger than the other flange portion in order that in case of incorrect mounting, the larger flange becomes obstructed and forms a visible indicator of misinstallation.
