Patent ID: 6986683

Claim:
An electrical coupling and components of coupling having electrical grounding contact members comprising: a first metal member; a second rotatable member with an annular recess formed around its inner surface and mounted on a part of the first member; and an electrical grounding contact member located in the annular recess arranged to engage the outer surface of the first member and the inner surface of the second member wherein the contact member maintains electrical continuity by its spring shape formed from a conductive strip or band with a series of slots along opposite edges to divide said strip into two series of spring contact fingers extending axially; said spring contact fingers bent inwardly into first and second resilient U-shaped portions; said spring contact fingers separated from one another by a straight intermediate portion provided by the said conductive strip, the resilient portions each having a straight inclined ramp directed centrally of said conductive strip and bent upwardly at its free ends into a contact region of curved profile, said left hand ramp forming a flared opening to said contact member; and said grounding contact member disposed so that a solid electrical contact is established between said grounding contact member and outer shell of said electrical coupling.
