Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 211 words
An electrical contact assembly comprising: a one piece inner sleeve formed from a unitary piece of sheet metal and adapted to receive a pin contact at the forward end and an electrical conductor at the rear end, said inner sleeve comprising a plurality of tines at the forward portion of said inner sleeve extending forwardly and adapted to mate with the pin contact, and a tubular hood portion having a forward end that is spaced from and surrounding said tines and a rearward end that terminates intermediate said inner sleeve in a rearwardly facing shoulder; an outer sleeve telescopically mounted on the rear wire receiving portion of said inner sleeve, said outer sleeve having a forward end that abuts the rearwardly facing shoulder of said tubular hood portion of said inner sleeve, said outer sleeve further including a forwardly facing shoulder on the outside surface thereof; and a second outer sleeve telescopically mounted over the tubular hood portion of said inner sleeve, said second outer sleeve including an enlarged portion having an internal rearwardly facing shoulder that engages the forwardly facing shoulder of said first outer sleeve, said enlarged portion being formed around the forwardly facing shoulder on said first outer sleeve to prevent axial movement of said first outer sleeve.
