Chain of electrical connector housings and a method of fitting a housing to an electrical contact

For use in a method of fitting an electrical connector housing to an electrical contact comprising feeding a chain of connector housings linked end-to-end in the direction of their length towards a fitting station, one end of one of each pair of adjacent housings of the chain fitting in and being releasably linked to an end of the other housing of said pair of adjacent housings, and, at said fitting station, effecting relative lengthwise movement between the housing nearest the fitting station and at the leading end of the chain and a contact in such a direction as to cause said leading housing to be fitted on to the contact, a chain of connector housings linked end-to-end in such a way that one end of one of each pair of adjacent housings of the chain fits in and is releasably linked to an end of the other housing of said pair of adjacent housings, wherein adjacent housings of the chain are releasably interlinked by interengaging means comprising at least one protuberance on a surface of one end of one of each pair of adjacent housings, which protuberance engages in a corresponding recess or recesses in a surface of an end of the other housing of said pair of adjacent housings, and wherein the interengaging means comprises an extension at one end of one of said pair of adjacent housings which engages in an aperture in an end of the other housing of said pair of adjacent housings.
