  • Patent number: 4274701
    Abstract: In the illustrated embodiment, the spring arms have an integral connecting web rearwardly from the pin contact region so as to form a U-shaped locking spring with rearwardly directed locking edges. As the spring system is assembled into a spring chamber, a tapering face progressively bends the legs of the locking spring inwardly, a locking edge springing outwardly to engage in front of a ledge as the system reaches the operating position, and the forward edge of the web restraining further forward movement. Each spring system is thus locked in operating position while being individually removable by means of a blade inserted from the forward side of a connector assembly having multiple rows of spring chambers.
