Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an IC socket provided with a locate plate for correcting bending of contact pins.

[Conventional technology]

A socket body in which a large number of contact pins are arranged in a row and a plurality of mounting holes that should be aligned with the plurality of positioning holes of the wiring board, and a large number of contact pins that are movably fitted in the socket body are inserted. An IC socket having a locate plate having a large number of small holes formed therein and adapted to correct bending of a contact pin or the like by moving the locate plate is known.

[Problems to be solved by the device]

By the way, the total number of IC sockets of this type is 300 to 4
Since about 00 contact pins are inserted through the locate plate which is relatively tight, it requires an unexpectedly large force to move the locate plate for correction. Conventionally,
In order to move the locate plate, it was necessary to insert the fingers etc. into the central opening of the socket body, so it often resulted in one-sided pushing of the locate plate, which made it difficult to move as desired. was there.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide an IC socket of the above-described type that enables the locate plate to be moved easily and smoothly. It is the one we are trying to provide.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, in the IC socket according to the present invention, at least two through holes are formed in the socket body, and the locate plate is aligned with these through holes and more than the through holes. At least two through holes having a small diameter are provided.

[Action]

If at least two projecting rods provided in a projecting jig prepared in advance are inserted into the through holes of the socket body and pushed in, the lower end surfaces of the projecting rods abut on the upper surface of the locate plate, and the locate plate. Can be moved downward.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. In the figure, 1 is a socket body having a large number of contact pins 2 arranged in a row, and 3 is a carrier positioning provided on the top surface of the socket body 1. Pins 4 are positioning bases installed on the socket body 1 and configured to be suitable for, for example, a TAB type IC package, 5 are a plurality of mounting holes penetrating the socket body 1, and 6 is the socket body 1 A large number of small holes 6a (Fig. 3), which are arranged at the bottom of the socket and into which all contact pins are slidably inserted, and two upper and lower hemispherical recesses 1a provided on the side wall of the central opening of the socket body 1. , 1b having a detachable hemispherical head, and a tongue having a hook portion that engages with the step portion 1c formed on the side wall of the central opening for regulating the lowermost position (position shown in the figure) Aligned with 6c and the mounting hole 5 on the socket body 1 A locate plate 7 having a through hole 6d having a diameter smaller than that of the mounting hole 5, 7 (FIG. 1) is pivotally supported by the socket body 1 and is a lid attached to the socket body 1 when the IC package is loaded, 8 Is a lock lever that is pivotally supported by the socket body 1 and holds the lid 7 in the closed position when the lid 7 is closed. 9 is two mounting holes 5 that are axially symmetric with respect to the central axis of the socket body 1. It is a projecting jig in which projecting rods 9a each having a predetermined length that can be fitted are planted.

Since the socket of the present invention is constructed as described above, when the locate plate 6 is in the position shown by the chain line in FIG. 3, that is, the position stored in the bottom of the socket body 1, the protruding rod of the protruding jig 9 is used.
When the 9a are inserted into the mounting holes 5 as shown in FIG. 2 and pushed in, the lower end surfaces thereof come into contact with the upper surface of the locate plate 6 (see FIG. 5), and the locate plate 6 is moved downward.
At that time, all the contact pin 2 portions projecting downward from the socket body 1 are straightened by being corrected by the small holes 6a of the locate plate 6. In this case, since the lowermost position of the locate plate 6 is regulated by the hook portion of the tongue piece 6c engaging with the step portion 1c formed on the side wall of the central opening of the socket body 1, it falls off from the socket body 1. There is nothing to do. Thus, the locate plate 6 can be easily moved to the position shown by a comparatively light force.

In the above embodiments, the mounting holes used for mounting the socket body 1 on the wiring board (not shown) are used as they are as the through holes, and the projecting jig 9 has a structure having two projecting rods. The present invention is not limited to this, and at least one pair of through holes may be provided separately from the mounting holes, or the projecting jig is provided with four protruding rods that utilize all the mounting holes 5. Needless to say, may be used. Also, in the embodiment, I for TAB type IC package is used.
Although described as a C socket, the present invention is not limited to this, and it is extremely easy to be modified for various types of IC packages, and these all belong to the scope of the present invention.

[Effect of device]

As described above, according to the present invention, by using a simple projecting jig, the locate plate can be moved extremely easily and lightly, and the bending of the contact pin or the like can be corrected quickly and appropriately. IC socket can be provided.
