Abstract

PURPOSE:To provide an IC socket adaptable for allowing its lead positions to correspond to IC terminals. CONSTITUTION:A socket body has an upper member 2a for receiving IC terminals and a lower member 2b having pins, and between them can be inserted a printed circuit board 5. Both surfaces of the circuit board are provided with conductors, which extend from terminal contacts and lead contacts and intersect with one another. Intersections of conductors are properly selected for connection so that the lead positions of the socket may freely correspond to the IC terminals.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC socket in which an IC lead is inserted and an IC is loaded.

[0002]

2. Description of the Related Art Conventionally, an IC socket of this product is used when mounting an IC on a printed circuit board.
An IC having an insertion opening depending on the number of C leads was used.

FIG. 2 is a perspective view of an IC socket showing a conventional example. This IC socket has, for example, as shown in FIG. 2, a contact pin having a lead portion 1a to which a pad portion of a printed circuit board is soldered at one end and an insertion opening 3 into which an IC terminal is inserted at the other end. 1 and a resin outer body 2 in which a plurality of the contact pins 1 are arranged and embedded.

In this IC socket, the contact pin 1 is located at a position corresponding to the terminal of the IC, and the position is fixed.

[0005]

In the conventional IC socket described above, for example, when the position of the terminal protruding from the IC package is changed, the IC is mechanically inserted into the terminal. There is a problem in versatility that the position of the contact pin on the IC socket side cannot be changed even if the position of the terminal is changed.

SUMMARY OF THE INVENTION An object of the present invention is to provide an IC socket capable of arbitrarily changing the position of the contact pin of the IC socket according to the change of the position of the terminal of the IC in order to solve such a problem. ..

[0007]

In the IC socket of the present invention, a contact into which a terminal of the IC is inserted is embedded.
A C side plate, a mounting side plate in which leads are embedded at positions corresponding to the contacts of the IC side plate, and a conductive member sandwiched between the mounting side plate and the IC side plate and contacting the contact and the lead. And a wiring that extends in one direction from the conductive member and intersects with each other on the front and back surfaces of the circuit board, and the intersections of the wirings are selected and connected.

The present invention will be described below with reference to the drawings.

FIGS. 1A to 1C show an IC socket according to an embodiment of the present invention, FIG. 1A is an exploded perspective view showing the entire structure, and FIG. 1B is a plan view of a circuit board shown in FIG. Figure,
(C) is a partial cross-sectional view of the circuit board of (b). This I
As shown in FIG. 1 (a), the C socket has an IC side plate 2a in which one end has a contact portion and a contact 1b having an insertion port into which an IC terminal is inserted at the other end side is embedded side by side, and this IC side plate. Lower plate 2b facing 2a and this lower plate 2b
Of the lead side 1a, which is embedded at a position facing the contact 1b of the IC, has one end protruding outward and a flat contact part at the other end, and the mounting hole 4 sandwiched between the IC side plate 2a and the lower side plate 2b.
The circuit board 5 is fixedly held by a, 4b and 4c.

As shown in FIG. 1B, the circuit board 5 has front wirings 7 extending in one direction from contact regions 6a to 6f which are in contact with the contacts 1b of the IC side plate 2a.
The front wiring 7 and the back wiring 8 that intersects with the front wiring 7 and extends from the contact region 6a are formed on the front and back surfaces. As shown in FIG. 1C, a through hole penetrating the circuit board 5 is formed at the crossing portion indicated by X, and the conductive member 9 is filled in the desired through hole so that the front wiring 7 and the back wiring are formed. You can connect.

In this way, if the socket itself is divided into two parts, and the circuit board 5 in which wiring is formed on the front and back two layers is sandwiched between them, and the front and back wirings are arbitrarily selected and connected, I
The arrangement of the C terminal and the arrangement of the leads of the IC socket can be freely changed. Further, the connection structure is
Although it is done by filling the conductive member in the through hole,
A conductive pin may be inserted into the through hole instead of the conductive member. In this case, there is an advantage that it is easier to change.

[0012]

As described above, according to the present invention, the socket main body is divided into the side plate into which the terminals of the IC are inserted and the lead or projecting side of the IC socket, and the space between the divided plate members. The circuit board is inserted into the circuit board, and wirings extending in one direction from the IC terminal contact area or the contact area of the leads and intersecting with each other are formed on the front and back surfaces of the circuit board, and these intersecting portions are arbitrarily selected and connected. By
This has the effect of providing a highly versatile IC socket in which the terminal arrangement of the IC and the lead arrangement of the IC socket can be freely selected.
