Shrinkable multiple bore connection system
View Patent ↗The present invention relates to a cable termination system for connection of a cylindrical member, such as a cable, within a housing containing multiple bores. One or more bores of the housing are held in a radially expanded state by one or more retaining devices. The cable may be coupled to a coupling device, such as a metallic lug, and inserted into a first bore such that a connection is made with a first mating device inserted into a second bore. Additionally, a second mating device may be inserted into a third bore to finalize the connection. After the connection is completed, each retaining device is de-coupled from its respective bore causing the housing surrounding the bore to contract to its original state, thereby forming a tight seal between the housing and the cable or mating device.
1. An apparatus for connecting two or more members, said apparatus comprising:
a housing comprising at least a first bore and a second bore arranged at a positive angle to each other, the housing substantially formed of a thermoset material;
wherein said first bore comprises a retaining device for holding at least a portion of said first bore in a radially expanded state;
a first member inserted into said first bore; and a second member inserted into said second bore;
wherein removing said retaining device from said first bore causes at least a position of said first bore to contract around said first member without heating the first bore.
2. The apparatus according to claim 1 , further comprising:
a connection device inserted into said second bore for connecting said first member to said second member.
3. The apparatus according to claim 1 , wherein said second bore comprises:
a second retaining device for holding at least a portion of said second bore in a radially expanded state;
wherein removing said second retaining device from said second bore causes said second bore to contract around said second member.
4. The apparatus according to claim 1 , wherein at least one of said first member and said second member comprises a plurality of members coupled together.
5. The apparatus according to claim 1 , wherein at least one of said first member and said second member comprises an electrical cable.
6. The apparatus according to claim 1 , wherein said first member comprises an electrical cable coupled to a metallic lug.
7. The apparatus according to claim 6 , wherein said metallic lug has a larger outside diameter than said electrical cable insulation.
8. The apparatus according to claim 1 , wherein said second member comprises a mating device.
9. The apparatus according to claim 1 , wherein said second member comprises an electrical cable coupled to a mating device.
10. The apparatus according to claim 1 , wherein said housing is fabricated of Ethylene Propylene Diene Monomer (“EPDM”).
11. The apparatus according to claim 1 , wherein said housing comprises a “T” configuration or a 600 ampere class elbow connector.
12. The apparatus according to claim 1 , wherein a diameter of said first bore is radially expanded.
13. The apparatus according to claim 1 , wherein said retaining device comprises a core.
14. The apparatus according to claim 1 , wherein said retaining device comprises nylon.
15. The apparatus according to claim 1 , wherein said retaining device comprises polyvinylchloride.
16. The apparatus according to claim 1 , wherein said retaining device comprises polycarbonate.
17. The apparatus according to claim 1 , wherein said retaining device comprises polypropylene cord wound in a cylindrical configuration; and wherein each radial section of said polypropylene cord is coupled to an adjacent radial section of said polypropylene cord for retaining said cylindrical configuration.
18. The apparatus according to claim 1 , wherein said retaining device comprising a reinforcement structure.
19. The apparatus according to claim 18 , wherein said reinforcement structure comprises a ring-like structure.
20. The apparatus according to claim 1 , wherein said retaining device is coupled to an interior of said first bore.
21. The apparatus according to claim 1 , wherein said retaining device is coupled to an exterior of said first bore.
22. The apparatus according to claim 1 , wherein said first bore is cylindrical.
23. The apparatus according to claim 1 , wherein said first bore comprises a tube having a varying diameter along its length.
24. The apparatus according to claim 2 , wherein said second bore is tapered.
25. The apparatus according to claim 2 , wherein said connection device is a threaded mating device.
