Abstract
A low impedance, spring loaded electric connector which comprises a cylindrical body receiving a conductive wire, a plunger guided by the body and having a tip for electrically contacting with an external conductive surface, a spring compressed between the body and the plunger. The plunger can slide along the body, and is biased by the spring to assure reliable contact with the conductive surface. This connector, further, includes a resilient and conducting cantilever making sliding contact between the plunger and the body for establishing an electric path bypassing the spring. The cantilever may be formed as a portion of the plunger, or alternatively may be made as a separate one attached to the plunger or the body.
Claims10
A low impedance, spring loaded connector for connecting electrical signals, comprising:
- a cylindrical body adapted to receive an electrically conductive wire attached thereto for electrical connection to an electrical circuit;
- a plunger guided by said body and slidingly movable between an extended position and a retracted position relative to said body, said plunger having a tip for making electrical contact with a conductive surface external to said body;
- spring means interposed between said body and said plunger for biasing said plunger toward the extended position;
- and
- cantilever means adapted to make electrical sliding contact between said plunger and said body so as to establish an electrical path short-circuiting said spring means and the electrical path so established providing a constant low resistance and inductance path independent of the state of the spring means.
