Claims

[Claims for Utility Model Registration] (1) A large number of lead terminals of an IC element are mounted one-on-one on a large number of contact pins arranged in a row on the socket body to facilitate electrical connection to the lead terminals. In such an IC socket, the IC is attached to the socket body so that it can move up and down within a predetermined range, and is pressed upward by a plurality of springs interposed between the IC socket and the socket body.
A floating plate for mounting an element, a cover attached to the socket body so as to be able to move up and down within a predetermined range and having a contact pin operating section, and a floating plate and a cover that are pivotally supported on the socket body. and a plurality of arms that engage with the floating plate, and when the cover is pushed down, the contact pin operating section retracts the contact pin to a position where it does not engage with the floating plate, and the floating plate is moved by a predetermined amount via the arm. When the pressure on the cover is released, the spring causes the cover and floating plate to rise to a predetermined position, and the contact pin returns to the position where it engages with the floating plate, thereby removing the IC element placed on the floating plate. An IC socket characterized in that a part of a contact pin is pressed into contact with a lead terminal. (2) The center part of the floating plate is attached to the socket body, and a protrusion for positioning the IC element to be mounted is formed on the upper surface of the floating plate, and the spring is attached concentrically and evenly to the floating plate. The IC socket according to claim (1) of the utility model registration, wherein the IC sockets are arranged at intervals and the arms are respectively arranged at each corner of the socket body. (3) The arm is constructed so that the length from its pivot center position to the tip that contacts the cover is longer than the length to the contact position of the flat surface that contacts the floating plate. IC socket described in scope of patent registration claim (1).
