Abstract

A contact includes a contact body including a tip, a spring beam opposite the tip and a shoulder between the tip and the spring beam. A plunger is movable with respect to the contact body and has the plunger having a tip and a shoulder. A biasing member is contained by the shoulders. The biasing member imparts a biasing force on the shoulder of the plunger. The biasing member is compressed as the plunger moves relative to the contact body. The spring beam engages the plunger between the tip and the shoulder of the plunger and is spring biased against the plunger to electrically couple the contact body and the plunger. An electrical path is defined from the tip of the plunger to the spring beam and to the tip of the contact body. The electrical path is routed outside of the biasing member.

Claims

1. A contact comprising:

a contact body including a tip, a spring beam opposite the tip and a shoulder between the tip and the spring beam;

a plunger movable with respect to the contact body, the plunger having a tip and a shoulder; and

a biasing member contained by the shoulders of the contact body and the plunger, the biasing member imparting a biasing force on the shoulder of the plunger, the biasing member being compressed as the plunger moves relative to the contact body;

wherein the spring beam engages the plunger between the tip and the shoulder of the plunger and is spring biased against the plunger to electrically couple the contact body and the plunger, an electrical path being defined from the tip of the plunger to the spring beam and to the tip of the contact body, the electrical path being routed outside of the biasing member.

2. The contact of claim 1, wherein the contact body and the plunger do not extend into the biasing member.

3. The contact of claim 1, wherein the contact body forms a receiving space that receives the biasing member such that the contact body extends along an exterior of the biasing member.

4. The contact of claim 1, wherein the contact body forms a receiving space between the shoulder and the spring beam that receives the biasing member and that receives an inner end of the plunger, the inner end being opposite the tip of the plunger.

5. The contact of claim 1, wherein the shoulder of the plunger is provided at an inner end of the plunger opposite the tip of the plunger, the shoulders of the contact body and the plunger being parallel to one another and spaced apart across a pocket, the biasing member being received in the pocket.

6. The contact of claim 1, wherein the contact body, between the tip and the shoulder, extends along a contact plane, the plunger, between the tip and the shoulder, extends along the contact plane, the plunger being movable relative to the contact body in a biasing direction parallel to the contact plane.

7. The contact of claim 1, wherein the contact body, between the tip and the shoulder, extends along a contact plane, the plunger, between the tip and the shoulder, extends along the contact plane, the shoulders being angled out of the contact plane to form a pocket therebetween that is shifted to one side of the contact plane, the biasing member being positioned in the pocket such that the biasing member is shifted to the side and outside of the contact plane.

8. The contact of claim 1, wherein the plunger includes a post extending into the biasing member, in an undeflected state, the biasing member extending beyond a distal end of the post.

9. The contact of claim 1, wherein the shoulder of the contact body is generally perpendicular to the shoulder of the plunger, the shoulder of the plunger engaging an end of the biasing member, the shoulder of the contact body engaging a side of the biasing member.

10. A contact comprising:

a plunger having a tip and a shoulder;

a contact body including a tip, a spring beam opposite the tip and a shoulder between the tip and the spring beam, the spring beam engaging the plunger between the tip and the shoulder of the plunger and being spring biased against the plunger to electrically couple the contact body and the plunger; and

a biasing member contained by the shoulders of the contact body and the plunger, the biasing member being a polymer element having spring characteristics, the biasing member imparting biasing forces on the shoulder of the plunger, the biasing member being compressed as the plunger moves relative to the contact body.

11. The contact of claim 10, wherein the contact body and the plunger do not extend into the biasing member.

12. The contact of claim 10, wherein the contact body forms a receiving space that receives the biasing member such that the contact body extends along an exterior of the biasing member.

13. The contact of claim 10, wherein the shoulder of the plunger is provided at an inner end of the plunger opposite the tip of the plunger, the shoulders of the contact body and the plunger being parallel to one another and spaced apart across a pocket, the biasing member being received in the pocket.

14. An electronic device comprising:

a socket body having a first surface and a second surface, the socket body having a plurality of contact chambers between the first and second surfaces; and

a plurality of contacts received in corresponding contact chambers, the contacts comprising;

a plunger having a tip and a shoulder, the tip of the plunger extending beyond the first surface for mating with a first component and being retractable into the socket body;

a contact body including a tip, a spring beam opposite the tip and a shoulder between the tip and the spring beam, the tip of the contact body extending beyond the second surface for mating with a second component and being retractable into the socket body, the spring beam engaging the plunger between the tip and the shoulder of the plunger and being spring biased against the plunger to electrically couple the contact body and the plunger; and

a biasing member contained by the shoulders of the contact body and the plunger, the biasing member imparting biasing forces on the shoulder of the plunger, the biasing member being compressed as the plunger moves relative to the contact body;

wherein an electrical path is defined from the tip of the plunger to the spring beam and to the tip of the contact body, the electrical path being routed outside of the biasing member.

15. The electronic device of claim 14, wherein the socket body includes a ledge, the biasing member being compressed between the ledge and the shoulder of the plunger.

16. The electronic device of claim 14, wherein the socket body has a base and a cover coupled to the base, the contact chambers being defined at least in the cover, the contacts being loaded into the contact chambers in the cover and the contact chambers being closed off by the base after the contacts are loaded into the contact chambers.

17. The electronic device of claim 14, wherein the contact body forms a receiving space that receives the biasing member such that the contact body extends along an exterior of the biasing member.

18. The electronic device of claim 14, wherein the contact body forms a receiving space between the shoulder and the spring beam that receives the biasing member and that receives an inner end of the plunger, the inner end being opposite the tip of the plunger.

19. The electronic device of claim 14, wherein the shoulder of the plunger is provided at an inner end of the plunger opposite the tip of the plunger, the shoulders of the contact body and the plunger being parallel to one another and spaced apart across a pocket, the biasing member being received in the pocket.

20. The electronic device of claim 14, wherein the shoulder of the contact body is generally perpendicular to the shoulder of the plunger, the shoulder of the plunger engaging an end of the biasing member, the shoulder of the contact body engaging a side of the biasing member.
