Ic socket

Abstract

Abstract PURPOSE:To prevent shortcircuiting resulting from deformation of contact piece and facilitate mounting on a printed circuit board by furnishing the lower lid of an IC socket concerned with a contact piece admitting electrical continuity only in the direction across the thickness, a wiring plate on which the contact piece is placed, a connection sheet admitting continuity only in the direction across the thickness, and a terminal to be put in continuity through an anisotropic electroconductive sheet. CONSTITUTION:A contact piece 4 consists of a rubber sheet admitting electrical continuity only in the direction across the thickness, and with it the lead 3a of an object to be tested 3 is put in resilient contact. This contact piece 4 is placed on a wiring plate 5, which is leading electrically to a terminal 7 fixed to a lower lid 1 through a connection sheet 6 admitting electrical continuity only in the direction across the thickness. This permits response to objects of different lead forms by means of replacement of contact piece 4 and wiring plate 5. If that portion of the conductor pattern on the wiring plate 5 where the contact piece 4 is placed is identical, terminal 7 to be put in continuity via the anisotropic conductive sheet 6 may be selected. This prevents shortcircuiting resulting from deformation of the contact piece and facilitates mounting on the printed circuit board.
