3A.

The IC socket 11 is fixed to a printed wiring board, and the printed wiring board and the pins 11A of the IC socket 11 are fixed.
Used to transmit signals with This is because the pin 11A cannot be connected to the printed wiring board by soldering or the like. The IC socket has a hole 11B, the pin portion of the socket pin 1 is inserted, and the socket pin 1 and the pin 11A conduct. The types of the IC socket 11 include, for example, a DIP type and a PGA type.

The insulating plate 15 insulates the IC socket 11 from the power plate 3. The insulating plate 15 has a large number of holes 15A into which the socket pins 1 are inserted, and the socket pins 1 inserted in the holes of the IC socket 11 and aligned vertically and horizontally are the other socket pins 1.
Prevent contact with.

Next, an external perspective view of the power supply plates 2 and 3 will be described with reference to FIG. The power supply plate 3 has many holes 3A, into which the socket pins 1 are inserted. The contact 3B that comes into contact with the conductive portion 1E of the socket pin 1 when the insulating portion 1D of the socket pin 1 is inserted into the hole 3A is attached to the hole 3A. A power supply plate 3C is attached to the end 3D of the power supply plate 3, and transmits power from the printed wiring board to the contact 3B. For example, + 5V supplied from a printed wiring board
The power is transmitted to the contact 3B, and when the conductive portion 1E of the socket pin 1 contacts the contact 3B of the power plate 3,
+ 5V power is transmitted to socket pin 1. The end 3D has four holes 3E through which the arms 12 of the fixing plate 13 pass.

The insulating plate 14 has the same shape as the insulating plate 15 and insulates the power supply plate 3 from the power supply plate 2. The difference between the power supply plate 2 and the power supply plate 3 is that, as shown in FIG. 3, the mounting position of the contact 3B of the power supply plate 3 is a position rotated by 90 ° about the center point of the hole 3B, and the power supply plate 2C Is located outside the power supply plate 3C, and the rest is the same. Power plate 2
For example, when ground power is supplied from the printed wiring board, the power is transmitted to the contact 2B, and the conductive portion 1 of the socket pin 1 is
When E contacts the contact 2 </ b> B of the power supply plate 2, the ground power is transmitted to the socket pin 1.

The fixing plate 13 has a large number of holes 13A, into which the socket pins 1 are inserted. A hole 13A is provided with a hole for receiving the head 1A of the socket pin 1, and a hole 1C is formed in the hole 1C in the head 1A.
C pin can be inserted. The holes 13A are stepped as shown in FIG. 4 to prevent the socket pins 1 from coming off.
The arm 12 has resiliency, has claws 12A at its tip, is attached to four fixing plates 13, and the claws 12A are in contact with the lower surface 11C of the IC socket 11 to fix the entire component.

Next, an assembly external view and a sectional view of the IC socket will be described with reference to FIGS. FIG. 5 is an external view of the assembly, and FIG. 6 is a sectional view. Reference numeral 16 in FIG. 6 is a printed wiring board, and 2F and 3F are wiring portions. Power is supplied to the power supply plate 2 from the wiring portion 2F, and power is supplied to the power supply plate 3 from the wiring portion 3F. By removing the fixing plate 13 and pulling out the socket pins 1 and inserting the socket pins 1 into the contacts 2B and 3B of the power plates 2 and 3 so that the conductive portions 1E of the socket pins 1 match, the power plates 2 and 3 are removed.
Is supplied to the socket pin 1. After inserting the socket pins 1, the fixing plate 13 is fitted back.

Next, the relationship between the contacts of the power supply plate and the conductive portions of the socket pins will be described with reference to FIG. The socket pin 1 is inserted into the hole 2A of the power supply plate 2 and the hole 3A of the power supply plate 3, and brings the conductive portion 1E of the socket pin 1 into contact with the contact 2B or the contact 3B. Power plate 2/3
Is supplied with power, so that the power is supplied through the socket pins 1 to the pins of the IC inserted into the holes 1C of the head 1A of the socket pins 1.

It should be noted that the present invention is an improvement of Japanese Patent Application No. 3-162326, in which a power supply ring 23 having a conductor plate 23A is provided.
And the arm 21A of the socket pin 21 is eliminated, and the shapes of the mold part of the socket pin and the arms 24A and 25A of the power supply plates 24 and 25 are different. Therefore, the power supply ring 23 hanging from the socket pin 21 is eliminated, so that the load capacity is reduced.

[0015]

According to the present invention, since the power supply according to the IC to be measured can be freely changed, it is not necessary to wire the power supply, and ICs having different power supply pin arrangements can be measured on the same board.
