Abstract
Abstract The invention relates to a current adaptor which can be connected to a current supply rail. The current adaptor comprises a housing with grips on either side whose free ends are bent in the form of a hook so as to grip around the current supply rail. The grips are hinged to the housing and those sides of each of the grips which extend beyond the pivot viewed from the free end, are pressed apart with the aid of a spring incorporated in the housing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
A current adaptor for use with a current supply rail which accommodates current carrying conductors, comprising a housing, a plurality of contact elements protruding from a surface of said housing for electrical connection to said current carrying conductors, two grip members hingedly attached to said housing for pivotal movement, said grip members being located on opposite sides of said housing and extending beyond said housing, the free ends of each grip member remote from the housing being bent toward the other grip member so as to grip around the current supply rail, a spring carried within said housing for engaging both grip members and urging the grip members on one side of the hinge point apart so that said bent ends are urged toward each other, and a resilient earthing contact carried by one of said grip members resiliently movable toward the other grip member.
