The figure is a cross-sectional view of the main part of the IC socket showing the state in which the IC package is mounted, and Figures 4A, B, and C are cross-sectional views of the main part showing the operation of pushing down the contact opening/closing member and displacing the contact backward. Figure A shows a state in which the front stage gentle slope is applied to start pressing down and the contact has started to separate from the IC terminal, and Figure B shows the state in which the pressing progresses and the rear stage steep slope is applied to cause the contact to move away. Figure 5C shows the state in which the rearward displacement is being made, and Figure 5C shows the state in which the push-down is completed and the rearward displacement is completed, respectively, and Figures A, B, and C show the embodiment in which the gentle slope of the front stage is made into an arcuate surface. Figure 4 is a cross-sectional view of the same essential parts shown in correspondence with the operating process in Figures A, B, and C, and Figure 6 is a cross-sectional view of a single-stage inclined contact pressing part showing an embodiment that is used in combination with the above-mentioned two-stage inclined contact pressing part. be. 1...Socket body, 2...IC package cage,

Claims

[Claims for Utility Model Registration] (1) A socket body having a large number of contacts arranged to make contact with the terminals of the IC package;
A contact opening/closing member is provided on the socket body so as to be movable up and down, and displaces the contact backward against elasticity when pressed down to release the contact and release the IC mounting part, the contact opening/closing member In the IC socket, the contact pressing portion is provided with a contact pressing portion that applies a backward displacement force to the contact, and the contact pressing portion that applies a rearward displacement force to the contact is formed by an inclined surface, and the inclined surface is formed so that the front pressing portion is loosened. A contact opening/closing mechanism in an IC socket, characterized in that the rear pressing portion is formed as a steep slope. (2) The IC according to claim 1, wherein the gentle slope at the front stage and the steep slope at the rear stage are both linear surfaces.
Contact opening/closing mechanism in socket. (3) The contact opening/closing mechanism in an IC socket according to claim 1, wherein the gentle slope at the front stage is formed into an arcuate surface.
