2. Description of the Related Art FIG. 26 shows a conventional example. FIG. 26
In, the electrical component socket 101 includes a substantially rectangular socket body 102 made of an insulating material. The socket body 102 has a plurality of connectors 103 arranged in a regular lattice shape or a houndstooth lattice shape, and a substantially rectangular moving plate 104 made of an insulating material is assembled laterally along the upper surface of the socket body 102. The moving plate 104 has a plurality of through holes 105.
Are formed in a lattice shape or a zigzag arrangement, and a tool receiving portion 106 is formed to bulge upward at an end portion of the moving plate 104. The plurality of through holes 105, the terminals 108, and the connectors 103 correspond to each other.

In order to contact the electrical component 107 in the electrical component socket 101, first, the terminal 108 of the electrical component 107 is moved to the movable plate with the through hole 105 of the movable plate 104 and the connector 103 being displaced. It is inserted from the through hole 105 of 104 to the socket body 101 side. Next, after fitting the tool 109 into the tool receiving portion 106, the tool 10
9 is operated in one direction to move the moving plate 104 laterally in one direction indicated by arrow X ₁ . Then, the terminal 108 of the electric component 107
Moves laterally in one direction together with the moving plate 104 and the connector 103
To contact. After this, the tool 109 is removed from the tool receiving portion 106.

In order to release the contact of the electric component 107 in the electric component socket 101, the terminal 108 is completely in contact with the connector 103 as described above.
After fitting the tool 109 into the tool receiving portion 106, the tool 10
9 is operated in the other direction to move the moving plate 104 laterally in the other direction indicated by arrow X ₂ . Then, the terminal 108 of the electric component 107 laterally moves in the other direction together with the moving plate 104, and is separated from the connector 103 to be in the contact release state. After this, the tool 109 is removed from the tool receiving portion 106.

[0005]

When the electric component 107 is an IC package or the like having a terminal group with a fine pitch, the lateral movement distance of the moving plate 104 is usually a minute dimension of about 1 to 1.5 mm. The contact and the contact release are performed within this size range.

Therefore, when vibration or the like is applied in a state where the terminal 108 of the electric component 107 is in contact with the connector 103 of the socket body 102, the moving plate 104 is moved by the arrow X.
And traverses the ₂ becomes the other direction, the contact of the electrical component 107 has a problem that releasing inadvertently.

For example, in order to prevent the above problems, the moving plate 1
By inserting the lock pin between 04 and the socket body 102, the lateral movement of the moving plate 104 in the other direction is stopped,
Although it is possible to maintain the contact of the electric component 107, this method compels a troublesome work such as inserting and pulling out the lock pin.

In view of the above, the present invention provides a socket for electric parts in which a moving plate is laterally moved by a tool. In the socket for electric parts in which the moving plate is laterally moved by a tool to make the contact and the contact release, the electric component The purpose is to reliably prevent a prepared contact release.

[0009]

According to the present invention, by inserting a tool into a tool receiving portion provided in a socket body, the moving plate is moved laterally to make contact with and release contact with an electric component mounted on the moving plate. In the socket for electrical parts, the socket body is displaced to the disengagement position of the moving plate against the elasticity by pressing the tool on the socket body, allowing the moving plate to move laterally and allowing the electrical parts to be unloaded and unloaded. In addition, when the pressing by the tool is released, the movable plate is elastically restored to the engagement position, the lateral movement of the movable plate is stopped, and the contact of the electric component is held.

[0010]

When the contact of the electric component is released by the tool, the positioning mechanism is elastically deformed by the tool to release the engagement with the moving plate and allow the lateral movement from one direction to the other. Forming and subsequently applying a lateral force to the tool receiving portion of the moving plate with the tool causes the moving plate to move laterally from one direction to the other, releasing the contact of the electrical components.

On the other hand, in the case where the tool causes the electric parts to come into contact with each other, when the spring member is pressed by the tool to remove the resistance and the moving plate is moved laterally in one direction from the other direction, the electric parts are moved through the moving plate. Is contacted with the socket body, and the tool is released from the tool receiving portion to release the pressing force on the spring member, so that the spring member elastically restores to the engaging position with the moving plate and engages with the moving plate. , The lateral movement from the one direction to the other direction is restrained and the contact of the electric parts is maintained.

Therefore, even if vibration or the like acts on the socket for electric parts or the electric parts and an external force in the lateral direction acts on the moving plate, the positioning mechanism stops the lateral movement of the moving plate and makes contact with the electric parts. Is prevented from being inadvertently released.
