Abstract

A connector is miniaturized and while still preventing damage to locking lances. Deflectable first and second locking lances ( 19, 79 ) configured to lock first and second terminal fittings ( 11, 61 ) are arranged to be exposed on first and second facing surfaces ( 15, 75 ) of first and second housings ( 10, 60 ). When the first and second housings 10, 60 are assembled, the first and second locking lances ( 19, 79 ) are arranged back-to-back with each other. Surfaces of the first and second locking lances ( 19, 79 ) facing the first and second cavities ( 17, 77 ) on tip parts in a projecting direction are continuous without any step and include locking surfaces ( 23, 83 ) configured to lock the first and second terminal fittings ( 11, 61 ) on tips in the projecting direction.

First claim

What is claimed is:

1. A connector, comprising: a housing and a deflectable locking lance provided to be exposed on an outer surface of the housing, the locking lance ( 19 , 79 ) projecting into a cavity of the housing and being deflected and deformed by interfering with a terminal fitting being inserted into the cavity, and resiliently returning to retain and lock the terminal fitting when the terminal fitting is inserted properly into the cavity, wherein:
a cut portion is provided on a partition wall defining the cavity in the housing at a position adjacent to the locking lance and is open on the outer surface of the housing; and
the cut portion is provided with a guide edge extending from a position close to a supporting point of deflection of the locking lance toward a position distant therefrom and enabling a jig inserted through an open part on the outer surface of the housing to slide to release locking of the locking lance and the terminal fitting.

2. The connector of claim 1 , wherein a stopper edge configured to stop a sliding movement of the jig with the locking lance properly deflected and deformed is provided continuously with the guide edge on the cut portion at a position distant from the supporting point of deflection of the locking lance.

3. The connector of claim 1 , wherein plural cavities are arranged side by side in the housing and the cut portions are provided so that a plurality of the partition walls defining the respective cavities communicate in an arrangement direction.
