Description

[Detailed explanation of the idea] The present invention relates to an IC socket.

Conventionally, there have been IC sockets in which a socket pin having a mounting portion at the upper end is arranged corresponding to the lead terminal of the IC chip, and is integrally molded within a rectangular synthetic resin mounting board.

However, with such IC sockets, if the lead terminals of the IC chip are bent even slightly when inserting the chip, they will not fit smoothly into the socket pins, so you must straighten them before inserting them. Attaching the IC chip was extremely troublesome. Furthermore, there was a risk that the lead terminals would be damaged during attachment and detachment.

The present invention was devised in view of the above-mentioned conventional difficulties, and aims to provide an IC socket in which it is extremely easy to attach and detach an IC chip, and which can completely protect the lead terminals of the IC chip. It is.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The IC socket of the present invention consists of a socket body 1, an IC chip mounting board 2, and a protective cover 3.

The socket main body 1 has a rectangular shape, and a charging port 11 for the IC chip mounting board 2 is provided at the upper end thereof.
In addition, an IC is provided on the inside of the long side walls 12, 12.
The required number of rows of mounting grooves 13, 13 are provided at the same intervals as the lead terminals b of chip a, and the bottom 2
The above-mentioned mounting grooves 13, 13 are provided on both ends of the long side of 0.
The same number of through holes 15, 15 are provided in the corresponding positions, and the socket pin 1 is inserted into the mounting grooves 13, 13.
The elastic contact parts 14', 14' of 4, 14 are fitted so that their front parts protrude inwardly, and the fixed leg parts 14", 14" of the socket pins 14, 14 are inserted into the through hole 15. , 15 protrudes downward from the back side.

Reference numerals 16 and 16' denote insertion grooves provided on both short side walls, and one side wall 17 has a T-shaped hole and the other side wall 17' has a T-shaped hole. In addition, there is a square-shaped fitting groove 1 inside the corner on one side of the insertion groove 16.
8 and 18, and fitting grooves 19 and 19 of the same shape are respectively provided on the inside of the corner on the other insertion groove 16' side.

The IC chip mounting board 2 is formed in a size that allows it to be inserted into the socket main body 1 through the insertion opening 11, and the flat mounting portion 28 has a flat plate-shaped mounting portion 28 at both ends on the long side from the middle of the back surface from the end surface. A required number of rows of lead terminal accommodating grooves 21, 21 are provided corresponding to the elastic contact portions 4', 14' of the socket pins 14, 14, and vertical pieces 22, 21 are provided at both ends of the short side.
22' is provided upright, and the upper end thereof has a claw piece 23 extending outwardly.
23' is provided protrudingly.

One protrusion 24 that can fit into one of the insertion grooves 16 of the socket main body 1 is provided on the outer surface of one vertical piece 22, and one protrusion 24 that can fit into one of the insertion grooves 16 of the socket body 1 is provided on the outer surface of the other vertical piece 22'. Two protrusions 25, 25 which can be fitted into the insertion grooves 16' of the socket body 1 are arranged in parallel, and two protrusions 25, 25 which can be fitted into the insertion grooves 16' of the socket main body 1 are arranged in parallel. Possible shape hook pieces 26, 26
There are fitting grooves 19 at both ends of the other vertical piece 22'.
Hook pieces 27, 27 each having a shape that can be fitted into the hook 19 are provided opposite to each other.

The protective cover 3 is formed into a rectangular tube shape and has a lower side portion sized to fit on the outside of the socket main body 1. The claw piece 23 of the IC chip mounting board 2,
Guide edges 33, 33 are provided opposite each other with an interval 32, 32 corresponding to the width of 23', and between the guide edges 33, 33 there are locking pieces 34, 34 having stepped portions 35, 35 at the inner upper end portions. is attached. 36 indicates a partition plate.

Therefore, in the IC socket of the present invention, first of all,
The IC chip a is placed on the upper surface of the mounting part of the IC chip mounting board 2, and each lead terminal b is bent and fitted into the lead terminal accommodation grooves 21, 21, and mounted on the IC chip mounting board 2.

Next, insert the IC chip mounting board 2 from below the protective cover 3, and attach both claw pieces 23, 23' to the locking piece 34,
The protective cover 3 is inserted into the protective cover 3 by being engaged with the respective parts 34.

By grasping the upper part of the protective cover 3 and fitting its lower part onto the outside of the socket body 1, the IC chip mounting plate 2 is inserted into the socket body 1 through the insertion opening 11, and each lead terminal b of the IC chip a comes into contact with the elastic contact portion 14' of each socket pin 14, thereby establishing electrical continuity.

Note that one protrusion 24 of the IC chip mounting board 2 is fitted into one insertion groove 16 of the socket body 1, and the other protrusion 25, 25 is fitted into the other insertion groove 16'. Furthermore, one of the hook pieces 26, 26 is attached to the fitting grooves 18, 18 of the socket body 1 in an auxiliary manner.
In addition, the other hook pieces 27, 27 fit into the fitting grooves 19, 19.
Since they are designed to fit into each other and cannot be fitted in the opposite direction, there is no risk of misunderstanding the polarity of IC chip a when fitting.

According to the IC socket of the present invention as configured above,
Simply insert the IC chip mounting board with the IC chip installed inside the protective cover, and fit the lower part of the protective cover to the outside of the socket body fixed on the printed circuit board. Each lead terminal of the IC chip mounted above can be easily brought into contact with the socket pin inside the socket body.

Furthermore, since the protective cover can be easily removed from the socket body by grasping it and pulling it upward, the lead terminals of the IC chip can be easily removed from the socket pins.

Furthermore, since the entire outside of the IC chip is protected by a protective cover, failures due to various external causes can be prevented.

In addition, since the lead terminals of the IC chip are bent and fixed in advance into the lead terminal accommodation groove of the IC chip mounting board, they do not spread out when inserting the IC chip like in conventional IC sockets. There is no need to worry about straightening lead terminals that are bent or bent. Furthermore, since there is no risk of accidentally damaging the lead terminals when they are installed into the socket body, the lead terminals can be completely protected.

Further, the IC chip mounting board can be easily removed from the protective cover by simply releasing the claw piece from the locking piece of the protective cover. Then another
By attaching the IC chip to the IC chip mounting board and preparing it as a spare, there is an advantage that the IC chip can be replaced extremely easily.

Furthermore, conventionally it was necessary to use different IC sockets depending on the number of lead terminals on the IC chip, but the IC socket of the present invention can be used even when the number of lead terminals varies, such as 24 or 26. There are also potential benefits.
