Abstract: A connector includes a first housing, a second housing configured to be fitted to the first housing; a rotation member rotatably supported on the first housing; a lock arm including a lock part configured to lock with a lockable part of the first housing in a fitting completion position, an operation section configured to release the lock arm from a locked state, and a fulcrum part connected to an outer peripheral surface of the rotation member at a position between the lock part and the operation section, and configured to swing around the fulcrum part and to lock or release the lock arm by elastic deformation thereof; and a fitting detection member configured to detect a fitted state of the first housing and the second housing while being assembled to the rotation member and when moving in a locking direction from a temporally lock position to a fitting confirmation position.

Abstract: A connector includes a connector housing having a lock portion configured to lock a mated housing; a guide groove formed in the connector housing and guiding a fitting detection member from a temporary locking position to a final locking position; an arm portion having an engagement protrusion provided on an extended free end extending in a direction of approaching the lock portion from the fitting detection member and abutting against the lock portion at the temporary locking position; and a backlash filling protrusion that is formed on a protruding plate portion, to be engaged with the guide groove, of the fitting detection member, and is configured to tilt the fitting detection member in a direction in which a locking amount of the engagement protrusion with respect to the lock portion is increased at the temporary locking position.

Abstract: A connector includes: a housing having a lock portion; and a fitting assuring component attached to the housing and detecting whether the housing and the counterpart housing being fitted with each other. The fitting assuring component has a hollow portion to house at least part of the lock portion to surround the at least part of the lock portion upon the fitting assuring component being located at the preset attachment position, and the fitting assuring component preventing the lock portion from switching to cancellation of the state of the housing and the counterpart housing being fitted with each other by interfering with an inside wall of the hollow portion.

Abstract: A terminal reception chamber (201) of a connector (1) includes a first chamber (201A), a second chamber (201B) and a third chamber (201C). The connector includes a first housing (100) defining a mating terminal insertion hole (102), a second housing (200) defining the first chamber and the second chambers and attached to the first housing, and a third housing (300) defining the third chambers and attached to the first housing and the second housing to contact with the first housing and the second housing and to inseparably connect the first housing and the second housing.
