Abstract
An IC socket comprises a socket body, a cover urged upward, stage means for mounting an IC device, a slide plate urged downward for actuating contact pins, and two slide bars each of which is pivotably mounted, in one end region thereof, to the cover and has a pushing portion and a shaft in another end region thereof. With respect to each of the slide bars, the pushing portion abuts on a protruding portion of the slide plate and the shaft slidably abuts on a concave portion of a guide. When the cover is pushed down, the shafts open rightward and leftward at the bottom, to cause the pushing portions to push up the slide plate. As the shaft approaches a position under the protruding portion, reaction against the cover is reduced. In this manner, the IC socket is enabled to stay increase in resistance against the pushing-down operation of the cover.
Claims8
An IC socket comprising:
- a socket body;
- a cover member assuming a square shape with an opening formed therein as an entrance for an IC device, being mounted to said socket body to be vertically displaceable relative thereto, and being urged upward;
- a stage member mounted to said socket body for mounting the IC device thereon;
- a slide plate having force receiving portions, being mounted to said socket body to be vertically displaceable relative thereto for actuating a plurality of contact pins, and being urged downward;
- and
- slide bar sets each of which is arranged on each of mutually opposite sides of the square shape and includes at least one slide bar, each of the slide bars being pivotably mounted, in one end region thereof, to said cover member and forming a pushing portion, in another end region thereof, engageable with each of said force receiving portions of said slide plate;
- wherein the another end region of each of the slide bars is horizontally shifted along a guide portion arranged on said socket body in accordance with vertical displacement of said cover member to displace said slide plate vertically via the pushing portion.
