Abstract

An electrical connector is provided wherein the electrical connector includes an electrical connector neck which separates an electrical connector rear from an electrical connector front and wherein the electrical connector rear includes an electrical connector termination. The electrical connector includes a pre-mold material securely associated with the electrical connector to cover the electrical connector rear and the electrical connector termination. Additionally, an over-mold material is securely associated with the electrical connector to cover a portion of the pre-mold material.

Claims

1. An electrical connector assembly, comprising:

a cable having an electrical conductor;

an electrical connector having an electrical connector neck which separates an electrical connector rear from an electrical connector front, wherein the electrical connector neck includes an electrical connector neck diameter and the electrical connector rear includes an electrical connector termination connected to the electrical conductor,

a pre-mold material, wherein the pre-mold material is securely associated with the electrical connector assembly to cover the electrical connector rear, the electrical connector termination, and a portion of the electrical conductor and the cable; and

an over-mold material securely associated with the electrical connector assembly to cover a portion of the pre-mold material and the cable.

2. The electrical connector assembly of claim 1, wherein the pre-mold material includes at least one of a wiggle ring groove and an over-mold groove,

wherein if the pre-mold material includes an over-mold groove, a portion of the over-mold material is located within the over-mold groove.

3. The electrical connector assembly of claim 1, further comprising a spin ring having a spin ring front, a spin ring rear and a spin ring inner surface which defines a spin ring cavity having a spin ring cavity diameter, wherein the spin ring is movably associated with the electrical connector assembly such that the spin ring rear is located proximate the over-mold material and such that the spin ring covers the electrical connector front and the electrical connector rear.

4. The electrical connector assembly of claim 3, wherein the spin ring further includes a plurality of protrusions and a spin ring neck, wherein the plurality of protrusions are located proximate the spin ring front and wherein the spin ring neck is located within the spin ring cavity and includes a spin ring neck diameter.

5. The electrical connector assembly of claim 4, wherein the spin ring is movably associated with the electrical connector assembly such that the plurality of protrusions are located on one side of the electrical connector neck to be proximate the electrical connector front and the spin ring neck is located on the opposing side of the electrical connector neck to be proximate the electrical connector rear.

6. The electrical connector assembly of claim 4, wherein at least one of,

the spin ring inner surface is sized to be adjacent the surface of the pre-mold material to limit angular movement of the spin ring relative to the pre-mold material, and

the spin ring neck diameter is smaller than the electrical connector neck diameter.

7. The electrical connector assembly of claim 2, further comprising a wiggle ring, wherein when the wiggle ring is associated with the electrical connector assembly, the wiggle ring covers at least a portion of the pre-mold material between the over-mold groove and the electrical connector neck.

8. The electrical connector assembly of claim 7, wherein the wiggle ring includes a wiggle ring thickness sized to fit between the pre-mold material and the spin ring inner surface to limit angular movement of the spin ring.

9. The electrical connector assembly of claim 7, wherein the wiggle ring includes a wiggle ring groove interface and the pre-mold material includes a wiggle ring groove, wherein when the wiggle ring is associated with the electrical connector assembly, the wiggle ring groove interface is located within the wiggle ring groove to inhibit movement of the wiggle ring.

10. An electrical connector, comprising:

an electrical connector having an electrical connector neck which separates an electrical connector rear from an electrical connector front, wherein the electrical connector rear includes an electrical connector termination;

a pre-mold material, the pre-mold material being securely associated with the electrical connector to cover the electrical connector rear and the electrical connector termination; and

an over-mold material securely associated with the electrical connector to cover a portion of the pre-mold material.

11. The electrical connector assembly of claim 10, wherein the pre-mold material includes at least one of a wiggle ring groove and an over-mold groove,

wherein if the pre-mold material includes an over-mold groove, a portion of the over-mold material is located within the over-mold groove.

12. The electrical connector, of claim 10, further comprising a cable having an electrical conductor connected to the electrical connector termination, wherein the pre-mold material covers a portion of the electrical conductor and the cable.

13. The electrical connector of claim 10, further comprising a spin ring having a spin ring front, a spin ring rear and a spin ring inner surface which defines a spin ring cavity having a spin ring cavity diameter, wherein the spin ring is movably associated with the electrical connector such that the spin ring rear is located proximate the over-mold material and such that the spin ring covers the electrical connector front and the electrical connector rear.

14. The electrical connector of claim 13, wherein the spin ring further includes a plurality of protrusions and a spin ring neck, wherein the plurality of protrusions are located proximate the spin ring front and wherein the spin ring neck is located within the spin ring cavity and includes a spin ring neck diameter.

15. The electrical connector of claim 14, wherein the spin ring is movably associated with the electrical connector such that the plurality of protrusions are located on one side of the electrical connector neck to be proximate the electrical connector front and the spin ring neck is located on the opposing side of the electrical connector neck to be proximate the electrical connector rear.

16. The electrical connector of claim 14, wherein the electrical connector neck includes an electrical connector neck diameter and wherein the electrical connector further includes at least one of,

the spin ring inner surface is sized to be adjacent the surface of the pre-mold material to limit angular movement of the spin ring relative to the pre-mold material, and

the spin ring neck diameter is smaller than the electrical connector neck diameter.

17. The electrical connector assembly of claim 11, further comprising a wiggle ring, wherein when the wiggle ring is associated with the electrical connector, the wiggle ring covers at least a portion of the pre-mold material between the over-mold groove and the electrical connector neck.

18. The electrical connector assembly of claim 17, wherein the wiggle ring includes a wiggle ring thickness sized to fit between the pre-mold material and the spin ring inner surface to limit angular movement of the spin ring.

19. The electrical connector assembly of claim 17, wherein the wiggle ring includes a wiggle ring groove interface and the pre-mold material includes a wiggle ring groove, wherein when the wiggle ring is associated with the electrical connector, the wiggle ring groove interface is located within the wiggle ring groove to inhibit movement of the wiggle ring.
