Abstract
Cavities (21) into which terminal fittings (10) are insertable from behind are arranged at upper and lower stages in a housing (20), and locks (28) are provided at the lower surfaces of the respective cavities (21). Each lock (28) is formed by cutting a partition wall (22) partitioning the upper and lower cavities (21) or a bottom wall (23) of the housing (20), and includes an arm (29) supported at both front and rear ends. A locking section (30) engageable with an engaging edge (15) of the corresponding terminal fitting (10) is provided on the upper surface of each arm portion (29) to project into the cavity (21). When the terminal fitting (10) is inserted into the cavity (21), the locking section (30) is pushed by the terminal fitting (10) to resiliently deform the arm (29) into a substantially arched shape with its coupled portions at the front and rear ends as supporting points.

- 1. A connector comprising a housing with opposite front and rear ends, at least one cavity extending through the housing from the front end to the rear end and into which at least one terminal fitting is insertable, a lock provided on an inner surface of the cavity for resiliently locking the inserted terminal fittings, the lock being supported at opposite ends thereof, at least one of the ends of the lock defining a fork coupled to the housing at first and second spaced apart supports.
- 12. A connector comprising a housing with opposite front and rear ends, a front wall at the front end, at least one cavity extending from the rear end of the housing to the front wall, at least one insertion hole extending through the front wall and communicating with the cavity, a resiliently deflectable lock formed unitarily with the housing and disposed in the cavity, the lock having first and second spaced apart front supports coupled unitarily to the housing substantially at the front wall and a rear support joined unitarily to the housing at a location between the front wall of the housing and the rear end of the housing.
- 18. A connector comprising a housing with opposite front and rear ends, a front wall at the front end, cavities extending from the rear end of the housing to the front wall and insertion holes extending through the front wall and communicating respectively with the cavities, resiliently deflectable locks formed unitarily with the housing and disposed in the respective cavities, each said lock having first and second spaced apart front supports joined unitarily to the housings and a rear support joined unitarily to the housing at a location rearwardly of the front support.
