Insulated electrical conductor for panel mounting

Claim 1

An electrical connector assembly for panel mounting, the connector being of the type having an electrically conductive connector member and an electrically nonconductive sleeve member which surrounds and electrically isolates the connector member from the panel, the improvement comprising the combination of a sleeve member including a head portion having a surface for abutting the panel, and a tubular portion insertable through an opening in the panel, said tubular portion having a radially expandable section axially spaced from said head portion a distance approximating the desired panel thickness, and a connector member having a cylindrical outer surface, the outer diameter of at least part of said connector member being larger than the inner dimension of said radially expandable section so that insertion of said connector member causes said section to expand, said sleeve member and said connector member being provided with means for retaining the assembly in assembled condition including an annular recess in the outer surface of said connector member and a plurality of radially inwardly extending projections disposed to engage said recess, said recess and projection being disposed to engage when the members are assembled.
