[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an integrated circuit, especially a PGA.
(PIN GRID ARRAY) relates to a socket for an integrated circuit.

[0002]

2. Description of the Related Art Since the above-mentioned PGA integrated circuit has a large number of pin terminals such as 451 pins, the PGA integrated circuit is inserted into a socket and a predetermined number of pin terminals and socket contacts are formed. A great deal of force is required to make contact by pressure.

According to the present invention, a socket for a PGA integrated circuit can insert a pin terminal of a PGA integrated circuit into a socket with little force, and can contact the pin terminal and the socket contact with a predetermined pressure after the insertion. The purpose is to provide.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an insulating base in which a large number of socket contacts are arranged in a lattice pattern and provided therethrough, A pair of slidable sliding plates penetrating and arranged on the insulating base with a gap therebetween, and sliding the pair of sliding plates to deform socket contacts penetrating the sliding plates. By doing so, the socket contact
The contact pressure contact member is formed in a frame shape in which an inner peripheral wall is fitted to the insulating base and the pair of slide plates, the contact pressure contact member being pressed against a pin terminal of an integrated circuit disposed on the pair of slide plates. The upper part of the inner peripheral wall is formed as a guide part of the integrated circuit, and the upper opposing wall has a gap between the pair of sliding plates when the contact pressure contact member is moved downward. And a pressing portion that slides the sliding plate in a direction to narrow the distance.

[0005]

In the above configuration of the present invention, the PGA integrated circuit is fitted on the upper part of the inner peripheral wall of the frame-shaped contact pressure contact member and mounted on a pair of sliding plates. In this state, the pin terminals come in contact with the socket contacts without pressure.
Next, when the contact pressure contact member is moved downward, a pair of sliding plates slide on the insulating base in a direction in which the gap is narrowed by a pressing portion provided on the opposing wall of the inner peripheral wall, and a socket penetrating the sliding plate. The contacts are in pressure contact with the pin terminals of the integrated circuit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

[0007] In FIG. 1, reference numeral 1 denotes an insulating base, 2 ₁ and 2 ₂ are each slide plate, 3 is the contact pressing member.

[0008] The insulating base 1 is made of the upper plate 1 ₁ and the lower plate 1 ₂ which includes a top plate 1 ₁ and a number of socket contacts 4 which are arranged in a grid of lower plate 1 ₂ through vertically . 5 is the upper plate
A silicon resin is sealed between the _first bottom surface of the recess and the upper surface of the lower plate 1 ₂ time, which was soldered socket contact 4 projecting from the lower surface of the lower plate 1 ₂ to the wiring board (not shown) , solder is used to avoid out on the upper surface of the upper plate 1 ₁ through the socket contact 4. The pair of sliding plates 2 ₁ and 2 ₂ have a large number of through holes 6 penetrating the large number of socket contacts 4. 1
Except for the part that is disposed above and forms the gap 7, the peripheral part has an integrated circuit mounting part 8 that protrudes. The contact pressure contact member 3 is formed in a frame shape, and the lower part of the inner peripheral wall is fitted to the outer peripheral wall of the insulating base 1 so as to be movable up and down. A pair of pressing portions 10 are formed on the left and right sides of the opposing sides with the gap 7 interposed therebetween. This pressing part 1
0 fitted in a recess 11 formed in the upper plate 1 ₁ of the insulating base 1, a contact pressing member 3 has lowered from the upper position as shown in FIG. 2 to the position shown in FIG. 1 (B) when pressing the sliding plate 2 _1, 2 ₂ at the thick portion 12 in the direction in which the gap 7 is narrowed.

[0009] socket contact 4 that penetrates the sliding plate 1 _1, as best shown in FIG. 3 has a tongue 13 which is bent is cut in the central portion of the tip, the contact as shown in FIG. 2 When the press contact member 3 is located at the upper position, the press contact member 3 is fitted on the upper part of the inner peripheral wall of the contact press contact member 3 and slides on the sliding plates 2 ₁ and 2 _2.
The pin terminal 14 of the PGA integrated circuit 9 mounted on the integrated circuit mounting portion 8 of the first embodiment contacts the portion of the tip of the socket contact 4 where the tongue piece 13 exists without pressure. The sliding plate 1 ₂ socket contact 4 through the well is the same as that shown in FIG. 3, the position of the direction and the pin terminal 14 is opposite to FIG.

[0010] As shown in the FIG. 1 (B), the depressing of the contact pressing member 3, the sliding plate 2 ₁ and 2 ₂ are pressing portion 1
The gap 7 is slid in the direction in which the gap 7 is reduced by the thick portion 12 of 0,
The socket contact 4 contacts the pin terminal 14 with a predetermined pressure.

In FIGS. 1 and 2, reference numeral 15 denotes a lock member having an intermediate portion fixed to the outer peripheral wall of the contact pressure contact member 3, which is fixed to the outer peripheral wall of the insulating base 1 when the contact pressure contact member 3 is pushed down. Engage with the projection 16 provided,
The contact pressing member 3 is locked in this state.

[0012]

According to the present invention, since the present invention is constructed as described above, almost no force is required when inserting the pin terminal of the PGA integrated circuit into the socket, and after the insertion, the pin terminal and the socket contact are pressed at a predetermined pressure. Can be contacted with
In addition, the contact pressure contact member also serves as a guide when inserting and removing the PGA integrated circuit from the socket, and has effects such as a simple configuration.
