Abstract

A universal bushing is described herein. The universal bushing can include a base member and a first bushing member. The base member can include at least one outer portion and at least one inner wall that forms a first cavity, where the at least one inner wall has a perimeter that is substantially uniform along a first height of the at least one inner wall. The first bushing member can be removeably coupled to the base member and disposed within the first cavity, where the first bushing member includes at least one first wall having a first inner surface that forms a second cavity and a first outer surface, where the at least one first wall has a first inner perimeter that is substantially uniform along a second height of the at least one first wall, and where the first outer surface forms a first outer perimeter.

First claim

What is claimed is:

1. A universal bushing, comprising:
a base member comprising at least one outer portion and at least one inner wall that forms a first cavity, wherein the at least one inner wall has a perimeter that is substantially uniform along a first height of the at least one inner wall; and
a first bushing member removeably coupled to the base member and disposed within the first cavity, wherein the first bushing member comprises at least one first wall having a first inner surface that forms a second cavity and a first outer surface, wherein the at least one first wall has a first inner perimeter that is substantially uniform along a second height of the at least one first wall, and wherein the first outer surface forms a first outer perimeter,
wherein the first inner perimeter is less than the perimeter and the first outer perimeter,
wherein the first outer perimeter is slightly less than the perimeter,
wherein the first bushing member, once decoupled from the base member, is configured to recouple to the base member,
wherein the base member and the first bushing member are made of an elastomeric material,
wherein the first bushing member further comprises a first collar positioned at a first bottom end of the first bushing member and extending radially outward from the at least one first wall, and
wherein the first bushing member further comprises a first handling feature that extends laterally from a distal end of the first collar, wherein the first handling feature has a smooth inner surface and a smooth outer surface.

2. The universal bushing of claim 1 , further comprising:
a second bushing member removeably coupled to the first bushing member and disposed within the second cavity, wherein the second bushing member comprises at least one second wall having a second inner surface that forms a third cavity and a second outer surface, wherein the at least one second wall has a second inner perimeter that is substantially uniform along a third height of the at least one second wall, and wherein the second outer surface forms a second outer perimeter,
wherein the second inner perimeter is less than the second outer perimeter,
wherein the second outer perimeter is slightly less than the first inner perimeter,
wherein the second bushing member, once decoupled from the first bushing member, is configured to recouple to the first bushing member, and
wherein the second bushing member is made of the elastomeric material.

3. The universal bushing of claim 2 , wherein the first height is less than the second height, and wherein the second height is less than the third height.

4. The universal bushing of claim 3 , wherein the first collar has a first thickness that is substantially a first difference between the second height and the first height.

5. The universal bushing of claim 4 , wherein the second bushing member further comprises a second collar positioned at a second bottom end of the second bushing member and extending radially outward from the at least one second wall, wherein the second bushing member further comprises a second handling feature that extends laterally from a distal end of the second collar, wherein the second handling feature has a smooth inner surface and a smooth outer surface, wherein the second collar has a second thickness that is substantially a second difference between the third height and the second height.

6. The universal bushing of claim 5 , wherein the second handling feature extends beyond the first handling feature.

7. The universal bushing of claim 5 , wherein the base member is conically shaped, wherein the at least one outer portion of the base member comprises a tapered top and a tapered bottom.

8. An electrical connector, comprising:
a housing comprising a receiving area and a passage that traverses the receiving area; and
a universal bushing positioned within the receiving area, wherein the universal bushing comprises:
a base member comprising at least one outer portion and at least one inner wall that forms a first cavity, wherein the at least one inner wall has a perimeter that is substantially uniform along a first height of the at least one inner wall; and
a first bushing member removeably coupled to the base member and disposed within the first cavity, wherein the first bushing member comprises at least one first wall having a first inner surface that forms a second cavity and a first outer surface, wherein the at least one first wall has a first inner perimeter that is substantially uniform along a second height of the at least one first wall, and wherein the first outer surface forms a first outer perimeter,
wherein the first inner perimeter is less than the perimeter and the first outer perimeter,
wherein the first outer perimeter is slightly less than the perimeter,
wherein the first bushing member, once decoupled from the base member, is configured to recouple to the base member,
wherein the base member and the first bushing member are made of an elastomeric material,
wherein the first bushing member further comprises a first collar positioned at a first bottom end of the first bushing member and extending radially outward from the at least one first wall, and
wherein the first bushing member further comprises a first handling feature that extends laterally from a distal end of the first collar, wherein the first handling feature has a smooth inner surface and a smooth outer surface.

9. The electrical connector of claim 8 , further comprising:
a cable disposed within the passage and the second cavity, wherein the cable has an outer cable perimeter that is substantially the same as the first inner perimeter.

10. The electrical connector of claim 8 , wherein the universal bushing further comprises:
a second bushing member removeably coupled to the first bushing member and disposed within the second cavity, wherein the second bushing member comprises at least one second wall having a second inner surface that forms a third cavity and a second outer surface, wherein the at least one second wall has a second inner perimeter that is substantially uniform along a third height of the at least one second wall, and wherein the second outer surface forms a second outer perimeter,
wherein the second inner perimeter is less than the second outer perimeter,
wherein the second outer perimeter is slightly less than the first inner perimeter,
wherein the second bushing member, once decoupled from the first bushing member, is configured to recouple to the first bushing member,
wherein the second bushing member is made of the elastomeric material.

11. The electrical connector of claim 10 , further comprising:
a cable disposed within the passage and the third cavity, wherein the cable has an outer cable perimeter that is substantially the same as the second inner perimeter.

12. The electrical connector of claim 8 , wherein the housing further comprises a top and a bottom that are moveably coupled to each other, wherein the top and the bottom, when coupled to each other, form the receiving area, and wherein the passage traverses the receiving area, the top, and the bottom.

13. The electrical connector of claim 12 , wherein the universal bushing is removable when the top and the bottom of the housing are mechanically decoupled from each other.

14. The electrical connector of claim 12 , wherein the universal bushing forms a liquid-tight seal around the cable when the top and the bottom of the housing are mechanically coupled to each other.

15. The electrical connector of claim 14 , wherein the bottom of the housing comprises a first compression
