Abstract
To prevent deformation of lock portions and make a block connector smaller a dovetail-shaped lock groove 21 is formed at a front end of the upper surface of the lower housing 2 over the entire width, and a dovetail-shaped lock rib 22 which can be pressed into the lock groove 21 is formed on the lower surface of the upper housing 1. The lock rib 22 is divided into three divided ribs with clearances therebetween, and the projecting heights of the divided ribs differ. The lock groove 21 is formed to have a stepped shape. Recesses 32 which form jig insertion holes are so formed as to conform to the clearances of the lock rib 22. A rear locking mechanism is such that lock projections 30 are fitted into lock holes 29, and is relatively easily unlockable by rotating the front end of the upper housing 1. When the front ends of the upper and lower housings 1, 2 are disengaged by inserting a disengagement jig into the jig insertion hole, the lock rib 22 comes out of the lock groove while being guided by slanted side surfaces. If the front end of the upper housing 1 is subsequently rotated, the rear lock portion is also unlocked.
