Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
182 words
An input connector for an electricity distribution track in which exposed track conductors are housed, the input connector comprising: a casing, a pair of conductor elements, insulated from one another which are mounted within said casing, input terminals on said conductor elements for connecting input leads thereto, and a cam assembly operable from the exterior of the casing for moving said conductor elements between inner and outer positions, whereby said conductor elements, when moved apart to their outer positions, clamp the input connector to the track with said conductor elements in contact with the track conductors, said cam assembly comprising a cam, a camshaft a and a cam seat mounted for movement along the cam shaft, said cam seat being biased against the cam by said conductor elements, and said cam seat having a pair of arcuate-inclined surfaces for coaction with said cam, whereby rotation of said cam, in addition to causing lateral movement of the contact fingers between their inner and outer positions, effects a camming action on said conductor elements by allowing movement of said cam seat along the camshaft.

Claim 3
Dependent Claim
