Abstract
Abstract A relay socket for electrically connecting the terminals of a relay plug to external lead wires comprises a plurality of socket units assembled in a row, each of said socket units including a center base having upper recesses for receiving the terminals of the relay plug and two leadout portions provided at the opposite sides of said center base and each having leadout terminal beds defining a terminal space adapted to receive the external lead wire. Said upper recesses are each connected to a front recess formed on the front surface of said center base and to the terminal space defined by said leadout terminal bed, and metallic connecting means extend from the upper recess of said center base to the terminal space.

Claim 1
Independent Claim
231 words
A relay socket for electrically connecting the terminals of a relay plug to external lead wires comprising: a plurality of socket units assembled together in a row; each of said socket units having an exterior wall surface separably fittable in front-to-back relationship with the complementary wall surface of an adjacent one of said socket units, each of said socket units having a center base disposed at the center portion of said socket unit and also having two leadout portions disposed at the opposite sides of said center base; each of said center bases having an upper surface formed with a plurality of upper recesses for receiving the terminals of the relay plug, said upper recesses communicating respectively with front recesses formed on the front surface of said center base; each of said leadout portions having a separator defining the back surface of said leadout portion, a plurality of leadout terminal beds mounted on said separator, each of said leadout terminal beds defining a space adapted to receive an external lead wire and communicating with one of said front recesses; and metallic connecting means extending from said upper recesses of said center base to said spaces defined by said leadout terminal beds, said metallic connecting means comprising an L-shaped connecting plate having one of its ends narrowed to form a shoulder portion, and a pluG receiving terminal fitted on said shoulder portion.
