[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC socket having a large number of contact pins for electrically connecting to a large number of pin-shaped or spherical terminals arranged in a matrix on the bottom surface of an IC package, and more particularly, to an IC socket. Relates to an improvement of an open top type IC socket which moves a contact pin between a contact position and a non-contact position with respect to a terminal of an IC package by lateral movement of a moving plate with respect to a base member.

2. Description of the Related Art An open top type IC socket in which a contact pin having a spring property is moved between a contact position and a non-contact position with respect to a terminal of an IC package by lateral movement of a moving plate is disclosed in, for example, Japanese Patent Application Laid-Open No. 4-199979. Is disclosed in.
A conventional IC socket of this type has a base member in which a large number of contact pins are arranged in a matrix corresponding to the terminal arrangement of an IC package, a movable plate provided on the base member so as to be movable laterally, and a movable plate. An operating lever as an operating member for moving the plate laterally is provided. IC for moving board
A large number of through holes through which the terminals of the package and the contact pins are inserted are arranged and formed in a matrix. The operation lever has a gate shape, and two legs of the operation lever are attached to both ends of a support shaft extending through both side surfaces of the end portion of the base member, respectively, and at the end of the moving plate. It is connected to both ends of a transmission shaft extending through both side surfaces. The upper end of the operating lever is located above the other end of the base member and the moving plate. In this type of IC socket, when the upper end portion of the operation lever is pushed down by the operation member provided so as to be vertically movable with respect to the base member, the operation lever moves the moving plate laterally via the transmission shaft by the principle of leverage. Therefore, the contact pin can be moved from the contact position with the terminal of the IC package to the non-contact position against the spring force.

Further, in an IC socket intended for an IC package having a large number of terminals arranged in a matrix, corresponding contact pins in a matrix arrangement are moved between a contact position and a non-contact position for the terminals. Such a horizontally movable movable plate (sliding plate) is also disclosed, for example, in Japanese Utility Model Laid-Open No. 57-41280.

In the divided sliding plate in this case, each end is formed as a knife edge, and the pressing sliding member is pushed in along the guide groove to run, and the sliding plate is sequentially moved to move the contact pin. It is designed to open and close.

In the case of the conventional IC socket described above, in the former case, in order to move the moving plate laterally by a certain amount or more, it is necessary to secure the operation stroke of the operation lever, and therefore the leg of the operation lever is required. Since the parts have to be arranged outside both side surfaces of the moving plate, it is difficult to secure the strength of the operation lever, and the operation of the operation lever tends to be unstable. Further, since the pressing force of the operating member is concentrated on both ends of the transmission shaft that penetrates the end portion of the moving plate via the two legs of the operating lever, it is difficult to smoothly move the moving plate.

In the latter case, since the sliding plate is divided, the opening and closing operation of the contact pin can be easily performed, but the pressing sliding member must be inserted and removed laterally. Moreover, since the operation amount of the pressing sliding member is large, there is a problem that operability is poor and it is difficult to cope with an automatic machine.
Further, there is a problem that the opening / closing operation of the contact pin must be performed at two different ends.

Therefore, an object of the present invention is to provide a moving plate for moving a contact pin from a contact position to a non-contact position with respect to a terminal of an IC package to be mounted and an operating member for laterally moving the moving plate.

Therefore, it is possible to reduce the size of the IC socket and reduce the manufacturing cost. Further, since the moving plate 3 is divided into a plurality of plate pieces 11 each having a through hole 11a through which the transmission shaft 10 is inserted, the total number of contact pins is changed by changing the combination of the plate pieces 11. Different IC sockets can be easily manufactured. Even in the case where the plurality of actuating plates 8 in the above case are integrated, if the hole 8a serving as the engaging portion with the transmission shaft 10 is provided at an appropriate position, the same operational effect can be obtained. .
