Insertion of the electrode connecting pin 6 can be changed according to the burn-in width A and the real installation width B. Accordingly, signal lines 4 from a standard printed circuit board 2, in which an electric circuit which can replace the function of shrink lead pitch IC of the electric printed circuit board 1 is installed, can be connected to the circuit board 1 easily and surely, and exchange of the connecting pin 6 can also be easily performed.

Description

[Detailed Description of the Invention] C. Industrial Application Field] The present invention relates to a connector for connecting an electrical printed circuit prepared for mounting a shrink lead pitch IC, etc. to another electronic circuit, etc. be.

[Conventional technology]

7 is a side view showing a conventional connector, FIG. 8 is a bottom plan view of the connector shown in FIG. 7, and FIG. 9 is a partially enlarged perspective view of the connector shown in FIG. 8. In the figure, (3) is a connector, (4) is a signal line, (5) is a connection part, and αω is a pin. Since the distance C between the pins αω of the connector (3) connected to the electrical printed circuit board is fixed, two types of connectors (3) are required to accommodate the two types of sockets: burn-in width and mounting width. It was necessary, and it was not easy to replace it when the pin αω was bent or broken.

Next, the operation will be explained.

In electrical printed circuit boards, Yurin Kreebich IC
Before mounting the IC on the electrical printed circuit board, check the operation of the shrink word pitch IC to be mounted on the electrical printed circuit board.
Is it necessary to conduct the test using an electronic circuit that achieves the same operation as the one described above? For this reason, among the signal lines, the signal lines necessary for the same operation as the shrink lead pitch IC are connected one by one to the pattern prepared for the shrink lead pitch IC on the electrical printed circuit board. .

[Invention or problem to be solved]

Conventional connectors are constructed as described above, so if a pin is bent or broken, it is necessary to either repurchase it or repair it with solder. There was also the problem of having to purchase two types of connectors, one for burn-in width and one for mounting width.

This invention was made in order to solve the above-mentioned problems, and provides a function that can replace the function of a shrink lead pitch IC that is supposed to be mounted on the pattern of an electrical printed circuit board that matches the shrink lead pitch IC. To provide a connector that can easily and reliably connect a signal line from a standard electrical printed circuit board mounted on an electronic circuit with a 3D electronic circuit.

[Means to solve the problem]

This invention has a connector or a female-shaped connection electrode, an upper electrode is inserted into the connection electrode, a lower electrode integrated with the upper electrode is attached to an electrical printed circuit board for shrink lead pitch IC, and the The connection electrode is connected to a signal line connected to the connection electrode.

[Effect]

The connector according to the present invention is prepared with female-shaped connection electrodes arranged in the burn-in width and the mounting width, and the upper electrode of the electrode connection pin is inserted, and the lower electrode is connected to the burn-in width or the pattern of the electrical printed circuit board for the mounting width. The connection point opposite to the connection point with the upper electrode of the signal line is connected to the standard electrical printed circuit board.
