Lock plates 6b are connected to both ends of a top plate 6a that is placed over the opening of the IC storage chamber 3, and are snapped onto both sides of the IC socket 1 using the lock plates 6b.

The lock plate 6b is formed by bending both ends of the top plate 6a to extend along the side surface of the IC socket 1, and has locking claws 6b' bent inwardly at the tips.

One end of the lock plate 6b is connected to one corner of one end of the top plate 6a which is present on one side of the side surface of the connector main body 1, and the other end is separated from the top plate 6a and connected to the side surface of the connector main body 1. The locking claw 6b' is provided at the free end, and the locking claw 6b' is snapped into the locking step 9 provided on the side surface of the connector main body 1 to lock it. The configuration is as follows. In this way, the locking plate 8 is opened against elasticity using the connecting portion 6c at one end of the side surface of the connector main body 1 as a fulcrum, and the locking claw 6b' at the other end is released. . In addition, the tongue piece 6d is raised from the free end of the lock plate, and the tongue piece 6d
The tip faces the other corner of one end of the top plate 6a to form a gap to form a tool tip guide groove 7, and a tool tip receiving scratch is provided at the corner of the IC socket 1 facing the tool tip guide groove 7. A recessed portion 8 is formed.

The cover 6 is snapped onto both sides of the IC socket 1 with lock plates 6b, and the locking claws 6
b' is engaged with the locking step 9 formed on the side surface of the IC socket 1, and the IC socket 1 is fitted.

At this time, the locking plate 6b is opened using the connecting part 6c as a fulcrum and slides on the side surface of the IC socket 1 while resisting elasticity, reaches the formation position of the locking step part 9, elastically restores itself, and locks at the same place. leading to.

The cover 6 is firmly attached to the IC socket 1 by the snap fitting of the lock plate 6b, and the top plate 6a is placed over the opening of the IC storage chamber 3.
The IC 2 housed therein is held down to prevent it from flying out or falling out, and held in the accommodation chamber 3 without any play.

Also, when removing IC2, as shown in Figure 4,
By inserting the tip of a tool such as a screwdriver 10 into the guide groove 7 at the free end of the lock plate 6b and rotating it, the lock plate 6b is opened outward using the connecting portion 6c as a fulcrum, releasing the snap fitting and removing the cover. 6
Remove it and extract IC2.

As another example, in FIG. 5, the top plate 6a
The corner portion facing the tongue piece 6d is locked with the tip of the tongue piece 6d. IC2 contact piece 5 and IC socket 1
Depending on the contact form with the contact 4, the top plate 6
An upward force due to the elasticity of the contact 4 acts on a,
Depending on the magnitude of the upthrust force, the top plate 6a and the IC
2 may float. In the embodiment shown in FIG. 5, the corner of the top plate 6a that is separated from the lock plate 6b is engaged with the free end of the lock plate 6a using the tongue piece 6d, thereby opposing the above-mentioned upward force. This effectively prevents the top plate 6a from floating, and hence the IC 2 from floating.

As a means for locking the corner portion of the top plate 6a to the free end of the lock plate 6b, in this embodiment, a locking piece 6e is protruded from the corner portion of the top plate 6a, and the locking piece 6e is connected to the tongue piece 6d.
