It is turned on or off. Here, when the operating lever 8 is brought into contact with the protrusion 4h formed at the end of the socket body 4, the contact pressure between the electrode terminal 2a of the CPU 2 and the contact pin 5 of the socket body 4 is kept weak. The structure of the electrode terminal 2a of the CPU 2 is
The structure is not limited to that shown in FIG.

Next, the drive mechanism of the socket cover 3 as the moving plate according to this embodiment will be described with reference to FIG. As shown in FIG. 1A, the crank lever 12
Is an operating lever 8 coupled so as to be substantially orthogonal to each other.
And a crank structure including a crankshaft portion 11 having an eccentric shaft portion 11a. Therefore, when the rotational movement force is applied to the crankshaft portion 11 as the driving node of the cam device by the rotation of the operation lever, the rotation movement causes
The socket cover 3 as a follower of the cam device moves along the upper surface of the socket body 4.

FIG. 2 (a) is a sectional view taken along the line XX 'of FIG. 1 (a) when the operation lever 8 is rotated to the release position, and FIG. 2 (b) is the operation lever 8 in FIG. FIG. 2 is a sectional view taken along the line XX ′ of FIG. 1A when the is rotated to the set position. As shown in FIG. 2A, when the operation lever 8 is rotated in the direction of the arrow A1 from the releasing position, the crankshaft portion 11 interposed between the socket body 4 and the socket cover 3 is inserted.
However, while being in contact with the bearing groove 4g of the socket body 4, the socket body 4 side rotates at a fixed fulcrum in the direction of arrow A10 with the point P as a fulcrum. Accordingly, on the socket cover 3 side,
The eccentric shaft portion 11a moves around the crank shaft portion 11 by an arrow A1.
It is eccentrically rotated about a point P as a fulcrum in one direction. Eccentric shaft part 11
When a comes into contact with the first leg portion 31c of the socket cover end portion 3c, a rotational moment generated by this eccentric rotation is given to the socket cover 3, and the horizontal component of this rotational moment causes the socket cover 3 to move in the direction of arrow B1. Acts as a force to move to. On the other hand, as shown in FIG. 2B, when the operation lever 8 is rotated in the direction of the arrow A2 from the set position, the crankshaft portion 11 contacts the bearing groove 4g of the socket body 4 and moves toward the socket body 4 side. A fixed fulcrum is rotated in the direction of arrow A20 with P as a fulcrum. Along with this,
On the socket cover 3 side, the eccentric shaft portion 11a eccentrically rotates around the crank shaft portion 11 in the direction of arrow A21 with the point P as a fulcrum. The eccentric shaft portion 11a is the socket cover end portion 3
By contacting the second leg portion 32c of c, the rotational moment generated by this eccentric rotation is given to the socket cover 3, and the horizontal component of this rotational moment acts as a force for moving the socket cover 3 in the direction of arrow B2. To do.

In order to prevent the gap W between the socket main body 4 and the socket cover end portion 3c from rising as in the conventional socket shown in FIG. ) And (b), the socket cover end 3c is provided with a projection 3b and the socket body 4 is provided with a pressing portion 4b. Since the pressing portion 4b needs to press the protrusion 3b from the mounting direction of the CPU 2 against the push-up force acting on the socket cover end portion 3c, the pressing portion 4b provides a space for the protrusion 3b to enter. It has a shape in which the end 3e of the protrusion 3b abuts the space end 4e of the pressing portion 4b.

FIG. 2 (c) shows the ceiling portion of the socket cover 3 in which the contact portion G2 with the eccentric shaft portion 11a is surrounded by the first leg portion and the second leg portion of the socket cover end portion 3c. Three
It is sectional drawing of the XX 'line arrow direction of FIG.1 (a) at the time of being located in g. Rotational moment F acting on the contact portion G2
The horizontal component F1 of the above acts as a force for moving the socket cover 3 in the arrow B2 direction. On the other hand, the vertical component F2 of the rotation moment F acts as a pushing force of the socket cover 3. At the contact portion G3 between the protrusion 3b of the socket cover 3 and the pressing portion 4b of the socket body 4, a pushing force in the direction of arrow F3 acts on the protrusion 3b of the socket cover 3 against the pushing force F2. This pressing force F3 is caused by the end portion 3 of the socket cover 3 which has been the cause of the conventional defect.
It acts as a force that prevents the floating of c. (Hereinafter, margin)

The present inventor has also studied other embodiments in order to solve the above-mentioned conventional problems. The pushing force F2 that lifts the socket cover end 3c is generated because the contact portion between the eccentric shaft portion 11a of the crankshaft portion 11 and the socket cover 3 is the first portion of the socket cover end portion 3c.
This is a case where it is located on the ceiling portion 3g in a region surrounded by the leg portions 31c and the second leg portions 32c. Therefore, as shown by the solid line in FIG. 2D, the eccentric shaft portion 11a of the crank shaft portion 11,
It has been considered that the end portion 3c of the socket cover 3 is made higher so that the ceiling portion 3g of the region surrounded by the leg portions 31c and 32c of the socket cover end portion 3c does not come into contact with the end portion 3c. However, if the end 3c is raised, the socket becomes larger,
There is a problem that the volume occupied in the main board increases. On the other hand, as shown by the broken line, if the height of the end portion 3c of the socket cover 3 is not changed and the ceiling portion 3g of the region surrounded by the leg portions 31c and 32c of the socket cover end portion 3c is increased. However, there is a problem that the strength of the socket cover end portion 3c cannot be ensured. Therefore, it was determined that the present embodiment is optimal as the structure of the socket that prevents the socket cover end portion 3c from rising.

As described above, according to the socket 1 having the above-mentioned configuration, C
The electrode terminal of PU2 and the contact pin 5 of the socket body 4
When the contact pressure with is weakened, the pressing portion 4b of the socket body 4 presses the protrusion 3b of the socket cover 3 from the direction opposite to the pushing-up direction against the pushing-up force F2 to the socket cover end 3c. By providing the above, it is possible to prevent the socket cover end portion 3c from rising from the socket body 4.

Further, the distance between the shaft center of the crankshaft 11 and the operating position of the operating lever 8 is determined by the distance between the shaft center of the crankshaft 11 and the leg portion 31c of the socket cover end 3c of the eccentric shaft portion 11a. , The clamp lever 12 as a booster set to be longer than the distance to the abutting position on the socket cover 32c is provided, the socket cover 3 can be attached to the upper surface of the socket body 4 without operating the operation lever 8 with a large force. Can be reliably moved along.

In the above embodiment, the case where the CPU having the pin grid array type electrode terminals is mounted in the socket as the electronic component has been described.
Not limited to U, it can be applied to those in which an electronic component having an electrode terminal is mounted in a socket. Further, the present invention is not limited to electronic components having pin grid array type electrode terminals, and can be applied to those having ball grid array type electrode terminals, for example.

[0026]

According to the present invention, when the contact pressure between the electrode terminal of the electronic component and the electrode terminal of the socket body is weakened or released, the contact pressure is increased along the upper surface of the socket body. By providing a structure in which the pressing portion provided on the socket body presses the protrusion provided on the movable plate against the push-up force generated at the movable plate end that is movably attached, the movable plate end is It is possible to prevent the gap from being lifted from the main body. Therefore, there is an excellent effect that the appearance can be improved, the conventional cause of damage at the end of the moving plate can be eliminated, and the life of the socket can be extended.

In particular, according to the second aspect of the invention, the booster provided in the drive mechanism moves the movable plate along the upper surface of the socket body with a force larger than the force applied to the operating member. Therefore, there is an excellent effect that the contact pressure between the electrode terminal of the electronic component and the electrode terminal of the socket can be changed without applying a large force to the operating member.

Further, in particular, according to the invention of claim 3, by providing the operation member of the drive mechanism with the cam structure,
By converting the rotational movement of the operating member into a linear movement of the movable plate along the upper surface of the socket body, the contact pressure between the electrode terminal of the electronic component and the electrode terminal of the socket can be changed without providing a complicated structure. There is an excellent effect.
