Insulating casing for electrical spade terminal sockets

Claim 1

An insulating casing for an electrical spade terminal socket of the kind having a web and inwardly bent lateral gripping portions laterally spaced from one another, said casing consisting of an integral body of insulating material adapted to be slid over a said socket from the front end of the latter, the casing being of substantially rectangular cross-section having two opposite narrow sides and two opposite broad sides, front end stop means for the socket at the front end of the casing formed solely by two protuberances which project symmetrically into the internal space of the casing from the narrow sides thereof, rear stop means spaced from said front end end formed by two symmetrically disposed ratchet teeth projecting into the internal space of the casing from respective broad sides thereof for engaging the rear ends of said gripping portions of an inserted spade terminal socket, a rib on the internal surface of each said broad side extending along the longitudinal center line of the said broad side for supporting the web portion of an inserted spade terminal socket, said ribs and said teeth projecting from each said broad side into the internal space of the casing for substantially equal distances, and symmetrically disposed noses on both broad sides in the casing at the front end thereof for guiding a spade terminal into the socket, whereby the casing can be slid over a spade terminal socket from the front of the latter in either one of two orientations which are offset by 180° with respect to each other.
