ABSTRACT:
A lockable electrical connector assembly includes a female terminal having a terminating end for coupling to an electrical conductor and a receptacle end for receiving a male blade terminal having a locking opening therein. The receptacle end has a generally rectangular cross-section defined by a top wall, a bottom wall and a pair of short side walls. The bottom wall has a resilient tongue which includes a locking tang for locking engagement with the opening in the male blade terminal and a release cam follower for pulling the locking tang out of the opening to release the terminal. A dielectric housing has a passageway of a generally rectangular cross-section for receiving the female terminal in either of two opposite orientations. The passageway is defined by top, bottom and opposite side interior walls. Both the top and bottom interior walls have cam surfaces engageable with the release cam follower of the female terminal upon relative movement between the housing and the female terminal to effect pulling of the locking tang out of the opening in the male blade terminal to release the terminal regardless of the orientation of the female terminal in the housing passageway. The top wall of the female terminal includes a locking tab, and both the top and bottom interior walls of the housing have locking surfaces engageable with the locking tab regardless of the orientation of the female terminal in the housing passageway. Top and bottom wall portions of the receptacle end of the female terminal are bowed inwardly toward each other to define convex curved contact surfaces for engaging opposite sides of the male blade terminal, the curved contact surfaces having radii offset longitudinally of the terminal so that the contact surfaces sequentially engage the male blade terminal to reduce the insertion forces thereof.
