Abstract
A grounding contact member for electrically connecting cooperating metal shells in a coupling comprises a metal band divided along both edges into several spring contact fingers that are bent inwardly into two U-shape portions. The contact member is located in an annular recess around the inside of a coupling ring with the fingers at one end engaging the metal shell on which the coupling ring is mounted and the fingers at the other end engaging the other metal shell to which the coupling ring is connected.
Claims1
An electrical coupling comprising:
- a first metal member of circular section;
- a second rotatable member mounted on a part of the first member;
- an annular recess formed around an inner surface of the second member or an outer surface of the first member;
- and an electrical grounding contact member located in the annular recess, the contact member having a plurality of contact fingers extending axially of the coupling and bent into first and second resilient U-shape portions at opposite ends of each finger, the contact member being arranged to engage the outer surface of the first member and the inner surface of the second member such that the contact member makes electrical contact with at least the first member;
- and,
- wherein the first member is a first shell and the second member is a coupling ring, and wherein the annular recess is formed around the inner surface of the coupling ring;
- and,
- wherein one end of the contact member contacts said first shell and the other end of the contact member is arranged for contact with an outer surface of a second shell;
- and,
- wherein said first shell is formed with teeth around one end arranged to engage teeth on the second shell, and wherein the fingers at one end of the contact member contact an outer surface of the first shell in a region of teeth.
