Description

[Detailed Description of the Invention] The present invention relates to the structure of an IC socket with a lid that has a retaining lid (hereinafter abbreviated as the lid) for holding an IC.

In general, many IC sockets with lids have a lid pivotably supported at one end of the socket so as to be freely openable and closable, and fixed by a fixing claw (hereinafter abbreviated as "claw") also pivoted at the other end. However, with this structure, the lid retains the IC even if the nails are released, which is very inconvenient in terms of lid operability and speed in IC sockets for measurement where ICs are frequently inserted and removed. It is. FIG. 1 is a side view of a conventional IC socket with a lid, which has a structure in which a protrusion of a claw 1 fits into a recess of a lid 2 to hold it. FIG. 2 is a side view with the claw 1 released. As shown in FIG. 2, even if the claw 1 is released, the lid 2 continues to hold the IC 3, resulting in a decrease in work efficiency. Figure 3 shows the conventional
This is a perspective view of the IC socket when the lid is opened.
A state in which the lead 4 of No. 3 contacts the contact pin 5 and is held by the lid 2 and the claw 1 is explained.

The purpose of this invention was to solve the above-mentioned problem.
A projection (hereinafter abbreviated as lifting projection 6) for lifting the lid 2 at the same time as the claw 1 comes off is provided at the bottom of the claw 1, and a projection also serves as a rotation stopper on the back of the claw 1 to support the claw 1. (hereinafter abbreviated as supporting protrusion 7) is provided.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. Figure 4 shows an embodiment of the IC socket of the present invention, a sectional view when it is fixed with a claw, and Figure 5 is a diagram showing the IC socket of the present invention mounted on a board, and a side view when the claw is released. Figure 6 shows another embodiment of the IC socket of the present invention provided with a spring for flipping up, and is a plan view when the lid is opened. The IC socket of the present invention has a plurality of contact pins 5 that contact the leads 4 of the IC 3, pressure is applied by the lid 2 to ensure contact, and the claws 1 are used to securely hold the IC socket. A lifting protrusion 6 is provided at the bottom of the claw 1 so as to fit under the lid 2, and a supporting protrusion 7 that also serves to prevent the claw 1 from rotating is provided on the back side where the protrusion 6 is located. It is being When taking out the IC 3, the lid 2 is pushed up by the lifting protrusion 6 at the same time as the claw 1 is released, and the supporting protrusion 7 is rotated by a certain angle until it comes into contact with the substrate 9, as shown in FIG. As a result, the claw 1 does not tilt beyond a certain predetermined angle, resulting in a structure in which the lid 2 does not come off the lifting protrusion. Furthermore, if a spring 8 for lifting is provided as shown in FIG. 6, the lid 2 will be automatically lifted at the same time as the claw 1 is released, and this effect can be highly expected.

According to the present invention, the lid can be lifted by the lifting projection at the same time with the single action of releasing the fixation with the nail, making it easier to put your fingers on the lid and also making it easier to fix the lid with the nail again. Since the support protrusion serves as a rotation stopper, the lifting protrusion reliably goes under the lid and leads to a state where it can be easily fixed, resulting in extremely improved workability.
