Lever-type connector

摘要

A lever-type connector is configured so that a lock piece (65) of a lock (60) resiliently locks a locked portion (49) to hold a lever (50) at an end position when the lever (50) is rotated to the end position. The locked portion (49) is released from a locked state and the lever (50) is permitted to rotate toward an initial position by pulling up an unlocking portion (70) and forcibly deflecting the lock piece (65). Entrance restricting projections (75) project from facing surfaces of the protection walls (70) on an end position side of the unlocking portion (70) of the lock piece (65) in the lock (60).

主权项

1. A lever-type connector, comprising:
a housing into which a terminal fitting connected to an end of a wire is inserted from behind; a lever having two arms extending from an operating portion to define a U-shape, the arms being mounted rotatably on side surfaces of the housing, each arm including a cam groove configured to enable connection with a mating housing while rotating the lever from an initial position to an end position; a locked portion protruding from a rear surface of the housing; and a lock provided on the operating portion of the lever and including a resiliently deflectable cantilevered lock piece, an unlocking portion on a tip of the lock piece and protection walls standing on opposite sides of the lock piece in a direction perpendicular to a deflecting direction with clearances defined between the protection walls and the lock piece; wherein: the lock piece of the lock resiliently locks the locked portion to hold the lever at the end position, and the locked portion is released from a locked state and the lever is permitted to rotate toward the initial position by pulling up the unlocking portion and deflecting the lock piece; entrance restricting projections projecting from facing surfaces of the protection walls on an end position of the unlocking portion of the lock piece in the lock; and the entrance restricting projections overlap opposite edges of the unlocking portion when the housing is viewed from behind in a state where the lever is at the end position.
