Abstract
A spring contact assembly having a first plunger with a tail portion having a flat contact surface and a second plunger having a tail portion with a flat contact surface wherein the flat contact surfaces are overlapping and are surrounded by an external compression spring such that the sliding engagement of the flat surfaces increases during compression of the spring.
Claims14
A spring contact assembly comprising:
- a first contact member having a tail portion having a flat contact surface along a length of the tail portion and a cylindrical flange adjacent the tail portion having a portion of the cylindrical flange removed forming a flat truncated surface for aligning the first contact member;
- a second contact member having a tail portion having a flat contact surface along a length of the tail portion;
- and
- a compression spring attached to the first contact member tail portion and the second contact member tail portion,
- whereby the flat contact surface of the tail portion of the first contact member slidably engages the flat contact surface of the tail portion of the second contact member and increases in contact surface area of the flat surfaces during compression of the spring to overcome a torsional spring force on the first contact member and the second contact member.

A spring contact assembly comprising:
- a first flat contact member having a contact tip and a coplanar tail portion having a contact surface without a projection along a length of tail portion;
- a second flat contact member having a contact tip and a coplanar tail portion having a contact surface without a projection along a length of the tail portion;
- and
- a compression spring attached to the first flat contact member tail portion and the second flat contact member tail portion,
- whereby the contact surface of the tail portion of the first flat contact member overlappingly and slidably engages on top of the flat contact surface of the tail portion of the second flat contact member during compression of the spring contact assembly and whereby the contact tip of the first flat contact member is offset along an axis of sliding engagement of the flat contact surfaces from the contact tip of the second flat contact member and parallel to one another along the axis of sliding engagement.
