Connector with peripheral wall having an opening and a detector slidably engaging the peripheral wall adjacent the opening for preventing widening of the opening

摘要

A connector includes a first housing (10) with a terminal accommodating portion (11) surrounded by a peripheral wall (17), a second housing (60) connectable to the first housing (10), and a detector (40) to detect a connected state of the housings (10, 60) based on whether the detector (40) moves from an initial position to a detection position in a space between the terminal accommodating portion (11) and the peripheral wall (17). An opening (22) extends circumferentially in a part of the peripheral wall (17) and exposes the detector (40). Deformation regulating portions (23, 53) are formed on the peripheral wall (17) and the detector member (40) and permit movements of the detector (40) between the initial position and the detection position and regulate deformation of the peripheral wall (17) to enlarge an opening width of the opening (22) by being fit to each other.

1. A connector, comprising:
a first housing having a terminal accommodating portion and a peripheral wall substantially surrounding the terminal accommodating portion; a second housing connectable to the first housing; a detecting member configured to detect a connected state of the first and second housings based on whether or not the detecting member moves along a moving direction from an initial position to a detection position in a space between the terminal accommodating portion and the peripheral wall; an opening formed in the peripheral wall in a circumferential direction and configured to expose the detecting member to an outer peripheral side, the opening having opposed first and second side edges extending substantially parallel to the moving direction of the detector and spaced from one another by an opening width; first and second deformation regulating ribs formed on the peripheral wall at locations adjacent the first and second side edges of the opening, the ribs extending substantially parallel to the moving direction of the detecting member and projecting out from an external surface of the peripheral wall in directions substantially normal to the moving direction and to the width direction; and first and second deformation regulating grooves formed in the detecting member and configured to slidably engage the respective first and second deformation regulating ribs to permit movements of the detecting member along the moving direction between the initial position and the detecting position, the first and second deformation regulating grooves further sandwiching the respective first and second deformation regulating ribs from opposite sides in the width direction to regulate such deformation of the peripheral wall that would enlarge the opening width of the opening and to sandwich areas of the peripheral wall from inner and outer peripheral sides adjacent the opening.
