Description

[Detailed Description of the Invention] The present invention relates to a locking mechanism for an IC holding plate in an IC socket.

The IC holding plate in the IC socket is used to bring the IC terminals of the IC set in the IC socket into pressure contact with the contacts, and to hold the IC mounted.Therefore, it controls the closed state of the IC holding plate. A locking mechanism is essential for holding the device, and this invention adopts a push-knob mechanism as such a locking mechanism.
The push knob is held in the restoring direction by a spring material,
The restoring action automatically engages the lock piece provided at the free end of the IC holding plate and the engagement is self-maintained, and the engagement is achieved by a simple push operation against the spring material of the push knob. It is an object of the present invention to provide a locking mechanism for an IC holding plate that is easy to operate, has a simple configuration, and is inexpensive.

The present invention will now be described with reference to the drawings, which show an embodiment of the invention.

In the drawing, 1 is an IC socket base, and 4 is an IC holding plate made entirely of one sheet metal.A bearing 2 is provided at one end of the IC socket base 1, and a support shaft is attached to this bearing 2. 3 is inserted into a shaft insertion tube 4a formed in a curved manner at one end of the IC holding plate 4, and is rotatably supported. This IC holding plate 4 has an elastic IC holding part 4b formed by bending the middle part into a W-shape to form two IC pressing parts (linear pressure contact parts) 4c and 4d. A hanging piece 4e bent downward is formed at the other end of the hanging piece 4. A hook-shaped locking piece 4f is bent at the lower end of the hanging piece 4e, and the lower end of the locking piece 4f is inclined. Guide piece 4g
Form by bending. Further, at the end of the IC socket base 1 corresponding to the free end of the IC holding plate 4, a push knob 8, to which the locking piece 4f engages and disengages, is attached from the side of the end to the other end (the opening/closing fulcrum side of the IC holding plate). This push knob 8 has a locking piece engagement hole 8a that is open to the IC socket base.
A sloped surface 8b is formed on the inner wall surface of the locking piece engaging/disengaging hole 8a, which is synchronized with the slope of the slope guiding portion 4g of the locking piece 4f. Further, the push knob 8 is elastically supported by a spring member 9 in a direction opposite to the pushing direction (restoring direction), and is prevented from falling out by engaging a retaining piece 8c protruding from the side surface of the knob with the inner wall of the knob insertion hole. The knob 8 is placed in a state where it protrudes a certain amount from the end surface of the base 1.

Reference numeral 7 denotes a guide hole drilled in a direction perpendicular to the IC socket base 1 and the push knob 8. The guide hole 7 allows the lock piece engagement hole 8a to be opened to the IC socket base 1. The inclined guide portion 4g and the lock piece 4f formed in the lock piece are guided to the lock piece engaging/disengaging hole 8a of the push knob 8.

Then, the IC 6 is mounted on the socket base 1, the IC terminal 6a of the IC 6 is placed on the contact 5, and the IC holding plate 4 is rotated in the closing direction about the support shaft 3. The tilt guide portion 4g and lock piece 4f formed on the IC holding plate 4 are
It passes through the guide hole 7 formed in the IC socket base 1 to reach the hole 8a of the push knob 8, and by further pushing the IC holding plate 4 into the engagement hole 8a, the inclined surface 8b is pressurized by the above-mentioned inclined guide part 4g. direction in which the push knob 8 is depressed against the spring material 9 (push direction)
While moving the lock piece 4f into the engaging/disengaging hole 8a, at the same time as the lock piece reaches the lower surface side of the push knob 8, the push knob 8 is returned to its original position by the elasticity of the spring material 9, and the push knob 8 is
The lock piece 4f of the IC holding plate 4 is engaged with the lower surface of the IC holding plate 4 to complete the lock. In the same locked state, the IC pressing part 4 formed on the IC holding part 4b of the IC holding plate 4
c and 4d are for the measurement target mounted on the contact 5 above.
The IC 6 is held down elastically to maintain the IC mounting and contact.

Next, when the push knob 8 is pushed in the direction against the spring material 9, the lock piece 4f comes off from the lower surface of the push knob 8, and as a result, the IC holding part 4b
Due to the restoring force of the IC holding plate itself and the restoring force of the contact 5, which is stored in the Use your fingertips to open the IC6 to a position as shown in FIG. 1 where it will not interfere with the removal of the IC6, and remove the IC6. The push knob 8 returns to its original position due to the elasticity of the spring member 9 when the inclined guide portion 4g completely passes through the hole 8a, and waits in preparation for the next closing of the IC holding plate 4.

According to the present invention, the locking operation of the IC holding plate is performed by using the locking piece formed at the free end of the holding plate.
With the extremely simple operation of simply pushing the push knob into the locking/disengaging hole provided on the IC socket base, the knob's restoring action automatically locks and maintains the lock, as well as releasing the lock. This can be carried out extremely easily with a simple push operation, and has the advantage of providing a locking mechanism that is generally easy to operate, has a new appearance with few protrusions, and has a simple structure at a low cost.
