Connector
A connector ( 10 A) includes a housing ( 20 ), a seal member ( 80 ) to be arranged in a rear part of the housing ( 20 ), a holder ( 60 ) configured to prevent the seal ( 80 ) from coming out backward by being mounted on the housing 20 from behind the seal ( 80 ) and a wire cover ( 50 ) to be mounted on the housing ( 20 ) from behind the holder ( 60 ). The housing ( 20 ) includes an erroneous mounting preventing portion ( 39 ) configured to regulate the mounting of the holder ( 60 ) by interfering with the holder ( 60 ) when the holder ( 60 ) is mounted in an improper posture. The erroneous mounting preventing portion is configured as a cover lock ( 39 ) for fixing the wire cover ( 50 ) to the housing ( 20 ) by locking the wire cover ( 50 ).
1. A connector, comprising:
a terminal fitting to be connected to a wire;
a housing with a cavity into which the terminal fitting is inserted from behind;
a seal in a rear part of the housing and having a seal hole at a position communicating with the cavity, the wire being inserted into the seal hole in a liquid-tight manner;
a holder mounted on the housing from behind the seal to prevent the seal from coming out backward and including a through hole aligned with the seal hole, the wire being loosely inserted into the through hole; and
a wire cover mounted on the housing from behind the holder and covering the wire, wherein:
the housing includes an erroneous mounting preventing portion that interferes with the holder when the holder is in an improper posture; and
the erroneous mounting preventing portion is configured to lock the wire cover to the housing.
2. The connector of claim 1 , further comprising a tube projecting back at a rear part of the housing, the seal being accommodated in the tube in a liquid-tight manner and the erroneous mounting preventing portion is part of the tube.
3. The connector of claim 1 , wherein the holder is recessed to form a fitting groove and the erroneous mounting preventing portion is fit into the fitting groove to correct an inclination of the holder when the holder is mounted in the proper posture.
