Abstract
A contact type electrical connector includes a first plunger in contact with one member; a second plunger in contact with another member and electrically connected to the first plunger, whereby the two members are electrically connected through the first plunger; a cylindrical support member for slidably and elastically supporting the first and second plungers with a connection portion of the first plunger and a connection portion of the second plunger overlapping and electrically connected; and a compression coil spring surrounding the outer peripheries of the first and second plungers with the connection portions thereof supported by the cylindrical support member and brought into contact with a spring receiving portion of each of the plungers so as to urge the plungers apart. The cylindrical support member, which may be formed as a coil spring, serves to improve electrical connection between the plungers.
