Abstract

PURPOSE:To extremely simplify the fitting/removing actions of the connecting socket of an IC such as a memory and reduce the cost by using rotary pieces elastically deforming a contact piece, and performing the fitting/removing actions with only a lever. CONSTITUTION:When no IC 100 is fitted, side edges of rotary pieces 17, 18 are kept in contact with each other at the center portion, and both end sections of them are kept in contact with the terminal reception section 14a of a contact piece 14. Outer end portions of the rotary pieces 17, 18 are made thick, and the lower face sides are smoothly rounded into around shape and kept in contact with the floor face 11b of a frame 11. The rotary pieces 17, 18 are lightly pressed from both sides by the elastic force of the contact piece 14, and side edges of the center portions collide with the upper edge section 11c of the frame 11 and are stopped in a dog-legged shape. The terminal reception section 14a of the contact piece 14 is opened, and the terminal 101 of the IC 100 can be inserted from above. When an operation lever 19 is depressed, the rotary pieces 17, 18 are rotated with round-sections 17a, 18a serving as fulcrums, the reception section 14a is elastically deformed forcefully, and the connection in the closing direction can be performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC socket for temporarily connecting ICs such as a memory using an integrated circuit.

For example, a read-only memory (ROM) is a data writing device (ROM) when writing data.
It is attached to the WRITER) and is removed as soon as the data writing is completed.

[0003]

2. Description of the Related Art In order to temporarily attach an IC as described above, conventionally, the IC is fixed by screwing.
There have been sockets and IC sockets with a lock mechanism that locks the state by inserting and connecting the terminals of the IC.

[0004]

However, if the screw is tightened or loosened every time the IC is attached or detached, the operation is very complicated, and the conventional IC socket locking mechanism has a complicated structure and a low manufacturing cost. There were drawbacks such as high cost.

An object of the present invention is to provide an IC socket which solves the conventional drawbacks described above, has a simple structure, is low in manufacturing cost, and has a simple operation for attaching and detaching an IC.

[0006]

To achieve the above object, the IC socket of the present invention has a plurality of terminals 101 protruding from an IC 100 individually, as shown in FIG. 1 for explaining an embodiment. A plurality of contact pieces 14 made of a conductive material that can be opened and closed by elastic deformation so that they can be sandwiched, and the plurality of contact pieces 14 can be forcibly elastically deformed in the closing direction. Rotating pieces 17 and 18 rotatably provided, and one operating lever 19 for rotating the rotating pieces 17 and 18 so as to simultaneously open and close the plurality of contact pieces 14 at the same time. It is characterized by being provided.

The plurality of contact pieces 14 are arranged in two rows, and a pair of rotating pieces 17, 18 are arranged between them so that they contact each other on the inside and contact the contact pieces 14 on the outside. At the same time, the pair of rotating pieces 17, 18 are normally bent in a V shape, and the rotating pieces 17, 1
By making 8 substantially straight, the above-mentioned rotating pieces 17, 1
The contact piece 14 may be pressed and closed at the end of 8, and the operating lever 19 may be moved to the pair of rotating pieces 1.
It may be formed by directly connecting to one of the parts 7 and 18.

[0008]

By operating the rotating pieces 17 and 18 with the operating lever 19, the plurality of contact pieces 14 are simultaneously opened and closed. At this time, if the contact pieces 14 are elastically deformed in the closing direction, the plurality of terminals 101 of the IC 100 are individually sandwiched between the contact pieces 14, and the contact pieces are elastically deformed in the opening direction.
The IC 101 can be removed by removing the terminal 101 from each contact piece 14.

[0009]

Embodiments will be described with reference to the drawings.

FIG. 4 shows an IC (integrated circuit) 100 and an IC socket 10. The IC 100 is, for example, a read-only memory (ROM), and has a large number of terminals 101 protruding downward from both sides thereof. Terminal 10
1 is made of a metal plate and is arranged so that the surfaces of the terminals 100 on both sides face each other.

Reference numeral 11 denotes a frame of the IC socket 10, and holes 12 are provided on both sides of the upper surface of the frame so as to be aligned with the terminals 101 of the IC 100, and the terminals 101 are inserted into the holes 12 from above. Can be inserted.

In each hole 12, as shown in FIG.
A contact piece 14 made of a conductive metal plate material having a spring property is arranged, which has a U-shaped terminal receiving portion 14a having an open mouth upward and a leg portion 14b extending downward.

The U-shaped terminal receiving portion 14a of the contact piece 14 is
When an external force is applied from the side, it is elastically deformed inward and closed as shown by the chain double-dashed line in FIG. 3, and when the external force is released, the original U
Return to the glyph and open. Further, the foot portion 14b is projected below the frame 11 and connected to the wiring of the data writing device by soldering or the like.

A pair of rotating pieces 17 and 18 made of plastic mold are arranged in the frame 11, and an operating lever 19 is provided at the end of one rotating piece 17 and the rotating piece 17 is provided.
The frame 1 is formed by directly molding with
It can be operated outside of 1.

The state is shown more clearly in FIG. In the normal state in which the IC 100 is not attached, the rotating pieces 17 and 18 are in contact with each other at their central edges, and are in contact with the terminal receiving portion 14a of the contact piece 14 at both ends. .. Further, the outer end portions of the rotating pieces 17, 18 are formed thick, and the lower surface side thereof is smoothly rounded to form a so-called rounded shape.
It is in contact with the floor surface 11b of No. 1.

In the state shown in FIG. 1, both rotating pieces 17, 18 are provided.
Is lightly pressed from both sides by the elastic force of the contact piece 14, and the edge of the central portion collides with the upper edge portion 11c of the frame 11 and becomes a dogleg shape and stands still.

At this time, since the terminal receiving portion 14a of the contact piece 14 is open, the terminal 101 of the IC 100 can be inserted into the terminal receiving portion 14a from above.

The terminal 10 of the IC 100 is attached to the terminal receiving portion 14a.
1 is inserted, the operation lever 1 as shown in FIG.
Push down 9.

Then, the rotating pieces 17 and 18 are formed on the floor surface 11 of the frame 11 by the lower surface rounded portions 17a and 18a at both ends.
While sliding with respect to b, it is rotated about the rounded portions 17a and 18a as fulcrums to become a substantially straight line.

Then, the ends of the rotating pieces 17 and 18 move outward to press the terminal receiving portion 14a of the contact piece 14 outward, and the terminal receiving portion 14a is elastically deformed in the closing direction. To be done.

As a result, all terminals 101 of IC 100 are
However, at the same time, they are individually tightly sandwiched and fixed in the terminal receiving portion 14a of the contact piece 14, and electrically connected to the contact piece 14. At this time, the surface of the contact piece 14 has the terminal receiving portion 14
Since it is sandwiched in the direction of contacting a, the contact area is large and a good electrical connection state can be obtained.

When the IC 100 is attached to the IC socket 10 in this way and the processing such as data writing is completed, the operation lever 19 is pushed up to the original state as shown in FIGS. Piece 17, 18
Both ends of the contact move inward, and the terminal receiving portion 14a of the contact piece 14
Opens by its own elastic force, so that the IC 100 can be pulled out upward from the IC socket 10.

[0023]

Since the IC socket of the present invention has a simple structure in which the rotating piece for elastically deforming the contact piece is rotated by the operation lever, the manufacturing cost is low and the operation for attaching and detaching the IC is extremely simple. It has an excellent effect that
