Abstract

PROBLEM TO BE SOLVED: To prevent coming off of a cam member from a locking position in a ZIF socket for a PGA package. SOLUTION: The cam member 35 rotatably supported in a base housing is passed through an opening part 34 installed in a slide plate 32, and when the cam member 35 is rotated in the specified direction and the outer peripheral edge 40 of the cam member 35 presses the pressing surface 32a of the opening part 34 to slide the slide plate 32, the thickest position M of the cam member 35 passes the contact position 32b of the outer peripheral edge 40 with the pressing surface 32a in the specified direction. Thereby, the cam member 35 is always energized in the specified direction by the kickback force applied to the cam member 35 from a lead pin on the package side, and the coming off of the cam member 35 in the loosening direction (the opposite direction to the specified direction) is prevented.

FIG. 5A shows a PG in which the cam member is provided in a direction penetrating the base housing and the slide plate.
It is a top view of the cam member of the socket for A packages. The cam member 10 is attached in a direction penetrating the base housing and a slide plate 11 slidably provided thereon. The outer peripheral edge 12 of the cam member 10 forms a perfect circle and slides into the opening 18, and the center point 13 a of the rotation shaft 13 (shown by a dotted line) of the cam member 10 is eccentric from the center point 12 a of the outer peripheral edge 12. It is provided in the position where it did. For this reason,
By rotating the hexagonal hole 14 provided at the top of the cam member 10 in the direction of arrow A with a special tool or the like, the state shown in FIG. 5B is obtained, and the slide plate 11 is slid in the direction of arrow B. Has become.

The cam member 10 is slid by pressing the slide plate 11 with a pressing force X (see FIG. 5 (b)) and rotating together with the cam member 10.
The rotation of the cam member 10 is stopped at the position where the cam member 10 contacts the stopper 16. In this state, the lead pins of the PGA package engage with the terminals on the socket side, and the kickback force Y (FIG.
(See (b)) acts on the cam member 10 as a reaction force to the pressing force X. Cam member 10 and cam member 10
The kickback force Y acting between the slider and the slide plate 11 in contact with the terminal increases as the number of terminals (the number of lead pins) increases.

To solve this problem, for example, FIG.
As shown in (a), one end of the outer peripheral edge of the cam member 20 (the end on which the slide plate 21 is slid) is defined as a plane 22, and the cam member 20 slides the slide plate 21 in the direction of arrow B. The problem is solved by adopting a structure in which is locked. However, since the flat surface 22 is provided, the outer peripheral edge of the cam member 20 is no longer a perfect circle, and a gap (play) 24 between the cam member 20 and the opening 23 for accommodating the cam member 20 is formed.
This causes a problem that the ZIF function of the GA package socket becomes an obstacle. In addition, the cam member 20 is rotated about the rotation shaft 25 to move the flat surface 22 from the unlocked position (the state shown in FIG. 6B) to the locked position (the state shown in FIG. 6A). When locking to the end face 21, the load concentrates on the end (corner) 22a of the plane 22 and there is also a problem that the corner 22a is easily shaved.

FIG. 3A is an enlarged plan view of the cam member 35 shown in FIG. The outer peripheral edge 40 of the cam member 35 forms a perfect circle, and the rotation shaft 41 of the cam member 35 is provided at a position where its center point 41a is eccentric from the center point 40a of the outer peripheral edge 40. The cam member 35 of the present embodiment moves from the unlocked position state (FIGS. 3A and 1) to the locked position (FIG. 3).

As described above, when the PGA package is mounted on the socket 30, the cam member 35 receives the kickback force Y from the lead pin. In the PGA package socket 30 of the present embodiment, the kickback force Y always causes the cam member 35 to move in the direction of arrow A, that is, due to the displacement of the center points 40a and 41a in the direction along the pressing surface 32a, It acts as a turning force in the direction opposite to the direction in which the cam member 35 is removed from the lock position. For this reason, there is no possibility that the PGA package is loosened from the socket 30 and an electrical contact failure does not occur. Further, since the outer peripheral edge 40 of the cam member 35 can be made a perfect circle, rattling which deteriorates the ZIF function of the socket 30 also occurs. Absent.

The reaction force Z with respect to the kickback force Y generated from 1a is separated by a distance d in the direction along the pressing surface 32a, and a clockwise moment force K acts on the cam member 50 by both the forces Y and Z. This makes it possible to avoid a situation in which the cam member 50 rotates counterclockwise in addition to intentionally applying a counterclockwise turning force to the cam member 50.
