Abstract

Connectors are provided herein for connecting two elongated members that are positioned in-line to one another. Advantageously, the connectors not only allow for connection of the two members to permit for mechanical, electrical, EMI, and/or grounding applications, the connectors have provisions for accommodating thermal expansion and offset, which may include angular and/or axial offset. In certain embodiments, one or more collapsible housing pins or collars are provided to permit assembly and disassembly by either extending the housing pin or collapsing the housing pin.

Claims

1. A method for establishing electrical communication between two conductor pins comprising:

providing a housing comprising an outer sleeve defining a sleeve longitudinal bore including;

providing a retaining cylinder slidable within the sleeve longitudinal bore, the sleeve longitudinal bore comprising at least two grooves each in contact with a canted coil spring;

sliding the retaining cylinder onto a first conductor pin or a second conductor pin that are in-line with one another; and

wherein the retaining cylinder comprises a cylinder longitudinal bore coaxial with the sleeve longitudinal bore and having at least one groove formed along an inner circumferential surface and containing a canted-coil spring, the cylinder longitudinal bore having the first conductor pin or the second conductor pin located therein.

2. The method of claim 1, further comprising a second retaining cylinder having the other one of the first conductor or the second conductor pin located therein.

3. The method of claim 1. Wherein retaining cylinder comprising a spherical section.

4. The method of claim 1, wherein the retaining cylinder comprises a groove formed along an outer surface area for receiving a canted coil spring.

5. The method of claim 1, wherein retaining cylinder comprises a base section having a first diameter and a receiving portion having a second smaller diameter.

6. The method of claim 5, wherein the base section and the receiving portion both comprising a retaining groove.

7. The method of claim 1, further comprising pushing a flange on the retaining cylinder against the outer sleeve before sliding the retaining cylinder onto the first conductor pin or the second conductor pin.

8. A method for establishing electrical communication between two conductor pins comprising:

providing a first pin comprising a length, a diameter, and an end;

the first pin being electrically conductive;

providing a second pin comprising a length, a diameter and an end spaced apart from the end of the first pin;

the second pin being electrically conductive;

sliding a housing comprising a housing bore comprising at least one housing groove in the direction of the first pin or the second pin or sliding the first pin or the second pin in the direction of the housing;

placing a canted coil spring in contact with the housing groove;

placing a retaining cylinder between the housing and the first pin or the second pin;

wherein the canted coil spring comprises a spring bore sized to receive the first pin or the second pin; and

wherein electrical communication between the first pin and the second pin passes, at least in part, through the housing.

9. The method of claim 8, further comprising placing a second retaining cylinder between the other one of the first pin or the second pin and the housing.

10. The method of claim 8, wherein the housing is integrally formed.

11. The method of claim 8, further comprising placing the canted coil spring in contact with the first pin or the second pin.

12. The method of claim 8, wherein the retaining cylinder comprises a spherical section.

13. The method of claim 8, wherein the first conduct pin and the second conductor pin are axially offset with one another, angularly offset with one another, or both.

14. The method of claim 8, further comprising placing a second canted coil spring between the first pin or the second pin and the retaining cylinder.

15. A method for establishing electrical communication between two conductor pins comprising:

providing a housing defining a longitudinal bore and made from a conductive material;

providing a first retaining cylinder and a second retaining cylinder slidable within the longitudinal bore, the first retaining cylinder and the second retaining cylinder each including a base having a base outer diameter and a collar comprising an outer collar diameter and a bore with at least one canted coil spring located within an inner circumferential groove of the bore,

sliding the collar of the first retaining cylinder to receive a first conductor pin, and

sliding the collar of the second retaining cylinder to receive a second conductor pin.

16. The method of claim 15, wherein the base comprises a spherical section.

17. The method of claim 15, wherein the collar comprises a flange.

18. The method of claim 15, wherein the housing is integrally formed.

19. The method of claim 15, further comprising a pin housing located around at least one of the first conductor pin and the second conductor pin.
