DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC socket,
In particular, the present invention relates to an IC socket for mounting an IC on a test board.

[0002]

2. Description of the Related Art FIG. 3 is a perspective view of an IC socket showing an example of the prior art. Conventionally, this type of IC socket has been used for the purpose of connecting external terminals of an IC to terminals of a test board. This IC socket is, for example, shown in FIG.
As shown in the figure, the IC
A socket body 16 in which a fixed terminal 21 is formed in contact with a lead of the socket body 16. One end of the socket body 16 is attached to the socket body 16 via a hinge mechanism 18, and the other end of the socket body 16 has a hole 2.
And an upper lid 17 having a hook 19 to be locked to zero.

Next, the function and operation of the IC socket will be described. First, when setting an IC, the upper lid 17 is opened and an IC (not shown) is inserted. Next, the upper lid 17 is closed, and the hook 19 is hung on the hole 20 of the socket body 16 and fixed. By doing so, the IC lead and the socket body 1
6 fixed terminals 21 are in close contact with each other, and are not displaced from each other. In addition, the leads of the IC, the fixed terminals 21 and the external terminals of the socket become conductive. When removing the IC, the hook 19 is again inserted into the hole 2 of the socket body 16.
0, and opened the top cover 17, and followed the procedure of working.

[0004]

As described above, in the conventional IC socket, the upper lid is closed and opened many times when the IC is taken in and out each time the work is performed. As a socket for a test board used in mass production of ICs, there is a problem that continuous mechanical work is difficult, and thus cannot be used.

It is an object of the present invention to provide an IC socket that can be loaded and unloaded continuously.

SUMMARY OF THE INVENTION An IC socket according to the present invention has a socket body having an opening through which an IC passes from one direction and having a space therein, and moves through the space of the socket body. A movable member for holding and releasing the IC; a terminal member in the space portion having a terminal for contacting a lead of the IC; and a spring member for applying a repulsive force to the movable member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIGS. 1A to 1C are a perspective view and a sectional view showing an IC socket according to an embodiment of the present invention in the order of operation. As shown in FIG. 1, this IC socket has a socket main body 1 having an opening 3 into which an upper lid 2 is fixed and an IC 22 is inserted, and a claw portion 4 at one end which slides in a recess of the main body 1 and is provided. A movable portion 5 having a movable terminal 5a corresponding to a lead of the IC 22 and a spring 8 provided at the bottom of the concave portion of the movable portion 5 and the socket body 1 for applying a repulsive force to the movable portion 5 are provided.

Next, the operation of this socket will be described. First, as shown in FIG. 1B, when the IC 22 is to be inserted, the claw portion 4 near the opening 3 is
The movable part 5 directly connected to the claw part 4 is pushed down with the insertion of the IC, and the IC 22 is easily inserted. Next, FIG.
As shown in (2), when the IC 22 is completely inserted, the claw portion 4 and the movable portion 5 that have been pressed rise again by the repulsive force of the spring 8, and the IC 22 is pressed and fixed to the upper lid 2. At this time, the movable part 5 moves up and down while contacting the fixed terminal inside the side surface of the socket body 1. Thus, the leads of the IC 22 and the external terminals 6 of the socket are electrically connected. Similarly, when the next IC is inserted while the previous IC 22 is loaded, the loaded IC 22 is pushed out from the opening 3.

FIGS. 2A and 2B are cross-sectional views showing the operation sequence of an IC socket according to another embodiment of the present invention.
As shown in FIG. 1, this IC socket has an opening 11 through which the IC passes in one direction, and has a recess on the upper side inside the socket body 9 and a claw 10 on one end by vertically passing through the recess of the socket body 9. A movable terminal 12 having a movable terminal 12, a spring 13 for applying a repulsive force to the movable unit 12, and a fixed terminal plate 15 attached to a surface corresponding to the depression and having contact terminals corresponding to IC leads.

Next, the operation of the IC socket will be described. First, as shown in FIG. 2A, when trying to insert the IC 22, the claw portion 10 is pushed up by the IC 22, the movable portion 12 is raised, and the IC 22 can be easily inserted. Next, as shown in FIG. 2B, when the IC 22 is completely inserted, the movable portion 12 is pressed down again by the force of the spring 13 to fix the IC 22. Thus, the leads of the IC 22 and the external terminals 6 of the socket are electrically connected.

[0012]

As described above, in the IC socket of the present invention, the opening for inserting and discharging the IC in one direction is provided in the socket body, and the claw portion which is pushed down by inserting the IC into this opening is provided. A movable part for opening the opening through which the IC passes in conjunction with the movable part; and when the IC is completely inserted, the movable part presses and fixes the IC.
By providing a spring for applying a contact pressure to the connection terminal that comes into contact with the lead, the insertion of the IC can be easily performed at the same time as the insertion and ejection, and the time can be reduced. In addition, there is an effect that continuous mechanical work can be performed and the socket can be used as a socket for a test board used in mass production.
