CONNECTOR

摘要

It is aimed to reliably restrict the insertion of a terminal fitting in an improper posture. A connector includes terminal fittings 40 to be inserted into terminal accommodating chambers (13) of a housing (10) successively through through holes (61) of a rubber plug holder (60) and sealing holes (51) of a one-piece rubber plug (50), restricting projections (44) projecting from the outer surfaces of the terminal fittings (40), wires (46) passing through the through holes (61) in a state where the terminal fittings (40) are inserted in the terminal accommodating chambers (13), and restricting portions (17) provided to be located in the terminal accommodating chambers (13) and configured to restrict inserting movements of the terminal fittings (40) by interfering with the restricting projections (44) halfway through when the terminal fittings (40) are inserted in an improper posture into the terminal accommodating chambers (13).

1. A connector, comprising:
a housing formed with a plurality of terminal accommodating chambers; a one-piece rubber plug formed with a plurality of sealing holes corresponding to the terminal accommodating chambers and mounted into a rear end part of the housing; a rubber plug holder formed with a plurality of through hole corresponding to the sealing holes and configured to hold the one-piece rubber plug in a state mounted in the housing by being mounted to face the rear surface of the one-piece rubber plug; terminal fittings to be inserted into the terminal accommodating chambers successively through the through holes and the sealing holes from behind the rubber plug holder; restricting projections projecting from the outer surfaces of the terminal fittings in a direction intersecting with an inserting direction into the terminal accommodating chambers; wires connected to rear end portions of the terminal fittings and passing through the through holes in a state where the terminal fittings are inserted in the terminal accommodating chambers; restricting portions provided to be located in the terminal accommodating chambers and configured to restrict an inserting movement of the terminal fitting by interfering with the restricting projection when it is attempted to insert the terminal fitting in an improper posture into the terminal accommodating chamber; fixed interference portions projecting from the inner wall surfaces of the terminal accommodating chambers and constituting the restricting portions; a retainer to be mounted into the housing to be located in the terminal accommodating chambers and displaceable between a partial locking position where the insertion of the terminal fittings into the terminal accommodating chambers is permitted and a full locking position where the retainer comes into contact with the terminal fittings inserted in the terminal accommodating chambers to be able to retain the terminal fittings; and movable interference portions formed on the retainer and constituting the restricting portions when the retainer is at the partial locking position.
