Abstract

An electrical contact assembly includes an electrically nonconductive base, a first electrical contact supported by the base and a second electrical contact supported by the base such that the first contact and the second contact are separated by a space. The first electrical contact is configured to engage a first external conductive circuit element and the a second electrical contact is configured to engage a second external conductive circuit element. The first contact and the second contact are configured such that a portion of the first contact and a portion of the second contact converge as the base moves in a first direction relative to the first and second external conductive circuit elements and diverge as the base moves in a second direction relative to the first and second external conductive circuit elements.

First claim

Having thus described various embodiments of the invention, what is claimed as new and desired to be protected by Letters Patent includes the following:

1. A contact assembly comprising:
a base;
a first electrical contact supported by the base and including a first segment connected to the base and a second segment configured to engage a first external conductive circuit element; and
a second electrical contact supported by the base and including a first segment connected to the base and a second segment configured to engage a second external conductive circuit element, the second electrical contact being separated from the first electrical contact by a space for at least partially receiving a conductive pin therebetween, the base being movable relative to the second segment of the first electrical contact and the second segment of the second electrical contact between a retracted position and an extended position when the second segment of the first electrical contact is engaged to the first external conductive element and the second segment of the second electrical contact is engaged to the second external conductive circuit element,
the first electrical contact and the second electrical contact being retained in a diverged position when the base is in the retracted position and a converged position when the base is in the extended position such that the first electrical contact and the second electrical contact do not engage the conductive pin when the base is in the retracted position and do engage the conductive pin when the base is in the extended position, wherein the first electrical contact and the second electrical contact pass through the base.

2. The contact assembly of claim 1 ,
the second segment of the first electrical contact being positioned on a first side of the base,
the second segment of the second electrical contact being positioned on a second side of the base opposite the first side.

3. The contact assembly of claim 1 , the first electrical contact and the second electrical contact being flexible to allow the base to shift relative to the second segment of the first electrical contact and the second segment of the second electrical contact.

4. The contact assembly of claim 1 , wherein the base is formed at least partially of an electrically nonconductive material.

5. The contact assembly of claim 1 , wherein the base is movable relative to the second segment of the first electrical contact and the second segment of the second electrical contact along an axis, the second segment of the first electrical contact and the second segment of the second electrical contact extending perpendicular to the axis for contacting the external conductive circuit elements.
