Abstract: A jack of the present invention has a contact strip arranged on a U-shaped metal member which is fitted astride onto a body thereof and another contact strip arranged on a seat plate which is inserted into the interior space of the body from the rear end. Accordingly, fewer seat plates are provided for insertion into the body as compared with the number of contact strips, and the interior space of the body can thus be reduced. Also, the number of openings arranged in the body for passing terminals of their respective seat plates through can be reduced thus allowing the body not to experience a reduction in its physical strength. As the side walls of the body are interposed between the U-shaped metal member and the seat plates, the body retains its physical strength even if the walls are reduced in thickness.

Abstract: A pin jack, an electric connector element having a bored hole to receive a pin plug, is improved to have flexible adaptability in light of the size of openings to be formed on a terminal plate. Normally audio class pin jacks are non-coaxial, but radio level or higher frequency class pin connectors are of coaxial cable formation. These different kinds of connectors need openings with different diameters which lead to terminal plates having mixed size openings in order to meet mixed mountings. This difficulty is solved by rendering a inventive pin jack with two different concentric mounting diameters, of which a larger one of the diameters, which may be referred to as jacket ring, is externally formed to cover a portion of a cylindrical extension and is to be integrally connected to a cubic body base.
