Abstract

The present invention is directed to an integrally formed clip ring made out of a conductive resilient material such as beryllium copper. The clip ring is used for retaining a male member and a female member of an electrical connector and for forming a ground circuit between the male member and the female member of the electrical connector. The clip ring of the present invention fully engages the outside diameter of the male retaining groove and the inside diameter of the female retaining groove simultaneously. Advantageously, this eliminates the potential for discontinuities in a ground circuit in a vibrational environment. The clip ring includes an annular-shaped body having an inner wall and an outer wall where the outer wall has a plurality of circumferentially spaced slots. The outer wall has a first end circumferentially spaced from a second end wherein when the clip ring is compressed a first end and a second end are brought into contact with each other. In this manner, a complete 360° contact is maintained when the male member and the female member are fully engaged.

Claims

1. A resilient electrically conductive clip ring, comprising:

an annular-shaped body having an inner wall and an outer wall;

said outer wall having a plurality of circumferentially spaced slots extending substantially through the whole entirety of said outer wall, thereby rendering said outer wall operatively elastically flexible radially inwardly toward said inner wall;

said body extending circumferentially for less than 360°

, and having first and second ends circumferentially spaced from each other and adapted to be brought into contact;

wherein said outer wall has a first section extending obliquely and away from an edge of said inner wall, and a second section extending obliquely from an edge of the first section and towards said inner wall.

2. The resilient clip ring of claim 1, wherein said body extends circumferentially for a fill 360°

when said first and second ends are brought into contact.

3. The resilient clip ring of claim 1, wherein said outer wall has a plurality of radially outwardly extending fingers.

4. The resilient clip ring of claim 1, wherein said first section is a ramp extending radially away from said inner wall.

5. The resilient clip ring of claim 1, wherein said second section is a ramp extending radially toward said inner wall.

6. The resilient clip ring of claim 1, wherein said body is made of beryllium copper.

7. The resilient clip ring of claim 1, wherein said clip ring is integrally formed.

8. A resilient electrically conductive clip ring for connecting a male connector with a mating female connector, said clip ring comprising:

an annular-shaped body having an inner wall and an outer wall;

said inner wall forming an electrical contact with an outside diameter of said male connector when said clip ring is positioned on said male connector;

said outer wall having a convex shape including a first section extending from an edge of said inner wall, a knuckle portion extending from an edge of said first section, and a second section extending from an edge of said knuckle portion,

said outer wall being operatively elastically flexible radially inwardly toward said inner wall and said knuckle portion forming an electrical contact with an inner diameter of said female connector when said clip ring is introduced into said female connector; and

said body extending circumferentially for less than 360°

, and having first and second ends circumferentially spaced from each other and adapted to be brought into non-overlapping contact.

9. The resilient clip ring of claim 8, wherein said body extends circumferentially for a full 360°

when said first and second ends are brought into contact.

10. The resilient clip ring of claim 8, wherein said body is made of beryllium copper.

11. The resilient clip ring of claim 8, wherein said clip ring is integrally formed.

12. The resilient clip ring of claim 8, wherein said first section is angled to form a lead in section when said clip ring is introduced into said female connector.

13. The resilient clip ring of claim 12, wherein said lead in section is a ramp.

14. The resilient clip ring of claim 8, wherein said second section is angled to form a lead out section when said clip ring is withdrawn from said female connector.

15. The resilient clip ring of claim 14, wherein said lead out section is a ramp.

16. The resilient clip ring of claim 8, wherein said outer wall has a plurality of circumferentially spaced slots and a plurality of radially outwardly extending fingers formed therebetween.

17. The resilient clip ring of claim 16, wherein said slots extend substantially through the whole entirety of said outer wall.

18. An electrical joint, comprising

a male electrical connector;

a mating female electrical connector; and

a resilient electrically conductive clip ring electrically connecting an outer diameter of said male connector with an inner diameter of said female connector, said clip ring comprising;

an annular-shaped body having an inner wall and an outer wall;

said inner wall engaging said outer diameter of said male connector;

said outer wall engaging said inner diameter of said female connector and having a plurality of circumferentially spaced slots, thereby rendering said outer wall operatively elastically flexible radially inwardly toward said inner wall when said clip ring is brought by said male connector into an interior of said female connector;

wherein said outer wall has a first section extending obliquely and away from an edge of said inner wall, and a second section extending obliquely from an edge of the first section and towards said inner wall.

19. The electrical joint of claim 18, wherein said plurality of circumferentially spaced slots extend substantially through the whole entirety of said outer wall.

20. The electrical joint of claim 18, wherein said inner wall and said outer wall fully engage said outer diameter of said male connector and said inner diameter of said female connector, respectively.

21. The electrical joint of claim 18, wherein said inner wall is positioned in a first groove formed in said outer diameter of said male connector.

22. The electrical joint of claim 21, wherein said outer wall is received within a second groove formed in said inner diameter of said female connector.

23. The electrical joint of claim 18, wherein said body extending circumferentially for less than 360°

, and having first and second ends circumferentially spaced from each other.

24. The electrical joint of claim 23, wherein said first and second ends are brought into non-overlapping contact when said male and female connectors are fully mated.
