On the other hand, the cover 15 is rotatably attached to the socket body 13 at the base end 15a side by the rotation shaft 14 and is urged in the opening direction by a spring 16. A locked portion 15c is formed on the distal end portion 15b side of the cover 15, and a latch 17 rotatably attached to the socket body 13 is engaged and disengaged with the locked portion 15c. Has become. The latch 17 is urged clockwise in FIG. 1 by the spring 18, that is, in the locking direction. When the cover 15 is rotated in the closing direction to complete the closing state, the latch 17 is engaged. Stop 15
c (see FIG. 1).

Further, the cover 1 is provided on the cover 15.
When the block 5 is closed, a pressure member 20 as “pressure means” for pressing the IC 12 from above and a lever member 21 as “drive means” for vertically moving the pressure member 20 are provided.

As shown in FIG. 3, the fixed shaft 22 fixed to the cover 15 has an insertion hole 21a.
And is rotatably mounted in the insertion hole 21.
A substantially triangular-shaped operation hole 21b is formed below “a”.

The pressure member 20 has a columnar portion 20a formed at a lower portion thereof, which is guided by a vertical wall 13d of the socket body 13, and a pair of support pieces 20b projecting upward. Actuating shaft 23 on piece 20b
Are fitted, and these operating shafts 23 are inserted into the operating holes 21 b of the lever member 21. Further, a play insertion hole 20c is formed in the pair of support pieces 20b above the operation shaft 23, and the fixed shaft 22 is loosely inserted into the play insertion hole 20c. Further, a coil spring 25 is disposed between the pressure member 20 and the cover 15 as “biasing means” for biasing the pressure member 20 downward. Then, the lower surface 20d of the pressure member 20 presses the upper surface of the IC 12 in a balanced manner over a wide range.

After the cover 15 is closed by the lever member 21 and the coil spring 25, the pressure member 20 is lowered to press the IC 12.
The pressure member 20 is formed by the pressure member columnar portion 20a and the socket body vertical wall 13d.
"Guiding means" is configured to guide each position of C12 to a position in which the positions are pressed substantially equilibrium, and then to guide while maintaining the position.

Next, the electrical component socket 1 having the above-described configuration will be described.
The method of using No. 1 will be described.

A number of IC sockets (not shown) are previously arranged on the printed wiring board, and the electrical component sockets 11 holding the ICs 12 are set in these IC sockets by, for example, an automatic machine.

The IC 12 to the electrical component socket 11
The attachment / detachment is performed as follows.

That is, first, the IC 12 is placed at a predetermined position in the recess 13 a of the socket body 13, and then the cover 15 is turned around the rotation shaft 14 in the closing direction against the urging force of the spring 16. Move. Then, as shown in FIG. 1, the closing of the cover 15 is completed by the latch 17 being locked to the locked portion 15 c of the cover 15.

At the time of this locking, the cover 15 is slightly lowered for a moment from the locking position (final position).

However, since the pressure member 20 is lifted upward by the lever member 21, even if the instantaneous lowering state occurs, the pressure member 20 is kept at the IC1 level.
Since there is no contact with the IC 2, the IC 12 is not damaged. Incidentally, in the case of a socket in which the pressure member 20 is pressed by the cover 15 and the IC 12 is pressed, the IC 12 may be damaged.

In this state, as shown in FIG. 4A, since the lever member 21 extends in the vertical direction, the operating shaft 23 protruding from the pressure member 20 into the operating hole 21b of the lever member 21. Is inserted, the pressure member 20 is pulled upward with the coil spring 25 compressed.

Next, from this state, the lever member 21 is rotated about the fixed shaft 22 by tilting the lever member 21 as shown in FIG. 4C, and the position of the operation hole 21b is changed. Moving. Thus, the urging force of the coil spring 25 causes the operating shaft 23 in the operating hole 21b to move downward, that is, the pressure member 20 to move downward. This pressure member 20 is the lever member 2
The amount of descent is determined according to the tilt angle of 1. The pressure member 20 is lowered by being guided by the cover 15, and the columnar portion 20 a is connected to the vertical wall 1 of the socket body 13.
By being guided by 3d, the IC 12 is lowered while being perpendicular to the upper surface of the IC 12. Accordingly, the upper surface of the IC 12 is uniformly pressed over a wide range by the lower surface 20d of the pressure member 20.

As described above, after the cover 15 is closed (after the predetermined position), the lever member 21 is tilted to lower the pressure member 20 separately from this operation. 20 can be moved vertically from above to below.
Can be pressed evenly over a wide range.
Therefore, since the terminal 12b near the rotation shaft 14 is not strongly pressed by the land 13c before the other parts, the deformation of the terminal 12b can be prevented.

FIG. 4B shows a state in which the pressure member 20 is lowered to the maximum while the IC 12 is not mounted. An arrow P in FIG.
5 shows the amount of deflection.

Thereafter, to take out the IC 12, the lever member 21 is returned to a position along the vertical direction as shown in FIG. Thereby, the operating hole 21 of the lever member 21
operating shaft 23 protruding from pressure member 20 inside b
Moves, the pressure member 20 is pulled up against the urging force of the coil spring 25, the lower surface 20d of the pressure member 20 is separated from the upper surface of the IC 12, and returns to the top dead center.

Next, the latch 17 is released from the locked portion 15c of the cover 15, and the cover 15 is opened. Thereby, the IC 12 can be taken out.

In particular, the size of the IC 12 is reduced, and
When 2b is formed of gold, tin or other soft metal, it is extremely effective to press each terminal 12b in a balanced manner as in the present invention.

[Second Embodiment of the Invention] FIGS. 6 to 12 show a second embodiment of the present invention.

In the second embodiment, a positioning groove 13f is formed on the side wall of the recess 13a of the socket body 13 along the vertical direction, and an insertion projection 20e inserted into the groove 13f is formed on the pressure member 20. The sphere 2 is placed between the coil spring 25 and the pressure member 20.
7 is provided, which is different from the first embodiment.

That is, as shown in FIG. 10, the positioning groove 13f is formed on the alignment plate 13g, which is a part of the socket body 13, and as shown in FIG. Are formed. As shown in FIG. 11, the insertion protrusions 20e are formed on both sides of the pressure member 20 at the columnar portions 20a.
It protrudes upward from a slightly upper position.
The guide body is constituted by the socket body positioning groove 13f and the pressure member insertion projection 20e.

Further, the spherical body 27 is held in a state where it is positioned in a tapered recess 20f formed inside the pressure member 20.

In such a case, when the cover 15 is tightened from the open state, the insertion protrusion 20 e of the pressure member 20 is moved to the positioning groove 13 f of the socket body 13.
Is guided up and down. As a result, the pressure member 20 is guided in a direction perpendicular to the upper surface of the IC 12.

Further, by disposing the sphere 27 between the pressure member 20 and the coil spring 25, the pressure member 20 can be easily moved with respect to the cover 15, so that the insertion protrusion 20e of the pressure member 20 can be removed. Followability in the case of being guided by the positioning groove 13f of the socket body 13 is improved.

FIG. 12B shows the lever member 21.
In a state where the IC 12 is not provided and the pressure member 20 is lowered most,
FIG. 12C shows a state where the IC 12 is disposed in a state where the lever member 21 is tilted to the maximum and the pressure member 2
0 indicates that the IC 12 is pressed.

Other configurations and operations are the same as those of the first embodiment, and therefore the description is omitted.

[Third Embodiment of the Invention] FIG. 13 shows a third embodiment of the present invention.

The third embodiment differs from the above embodiments in the configuration of the "driving means".

That is, the "driving means" of the third embodiment is constituted by connecting the lever member 21 and the pressure member 20 by the link member 29. , The pressure member 20 is lowered to press the IC 12, and conversely, by returning the lever member 21 to the initial position, the pressure member 20 is pulled up via the link member 29.

The other configuration and operation are the same as those of the second embodiment, and the description is omitted.

The socket for electric components of each of the above embodiments holds the IC 12 so that the IC 12 can be easily handled because the IC 12 is small and is not molded with resin. In the state
Although mounted on an IC socket, the electrical component socket of the present invention can of course be applied to the IC socket described above and other devices. The IC 12 according to the above embodiment has the terminal 12b formed on the lower surface of the IC body 12a.
In this case, the electrode can be pressed by the pressure member 20. Further, the shape of the coil spring 25 is not limited to a cylindrical shape, but may be a conical shape, a drum shape, or the like. Instead of the coil spring 25, a spring of another form such as a torsion spring may be used.

[0051]

As described above, according to the present invention, after the cover is closed, the driving means lowers the pressure means to press the electric parts. The pressure means can be vertically moved from above to below, and each position of the electric component can be pressed substantially equilibrium, so that deformation of the electrodes of the electric component can be prevented.

In some cases, the cover may slightly drop slightly from the final closing position immediately before the closing is completed. However, since the pressure means is moved independently of the rotation of the cover by the driving means, the pressure means is moved. Can be raised upward, so that even if the instantaneous lowering state occurs, the pressure means does not come into contact with the electric component, and this electric component can be prevented from being damaged.

According to the second aspect of the present invention, in addition to the above-mentioned effects, the operability is good because the pressure means can be moved up and down only by operating the lever member.

According to the third aspect of the present invention, in addition to the above-described effects, the force of the lever member is used for pulling up the pressure means, and the force for pressing the electric component is exerted by the urging force of the urging means. Therefore, the force acting on the lever member does not change the force pressing the electric component, so that the electric component can be pressed with a stable force.

According to the fifth aspect of the present invention, in addition to the above-described effects, a guide means is provided for guiding the pressure means to a position in which each position of the electric component is pressed substantially equilibrium, and thereafter maintaining the position. Thereby, it is possible to more reliably press the respective positions of the electric component in an equilibrium manner.

According to the sixth aspect of the present invention, in addition to the above effects, by forming the guide means on the socket body or the cover, it is not necessary to newly provide a separate member, and the pressure means can be vertically moved from above to below. Can be moved.

According to the seventh aspect of the present invention, the effects described in any one of the first to sixth aspects can be obtained even in an electric component in which a protruding electrode is provided on the lower surface of the electric component main body.

According to the eighth aspect of the invention, the effects described in any one of the first to sixth aspects can be obtained even in an electric component in which an electrode is protruded from a side of the electric component main body.
