Is equipped with a plurality of attachment / detachment portions 21a capable of freely attaching / detaching the short-circuit means 22 for electrically short-circuiting between any of the relay means 21-1 to 21-N. To be achieved.

[0012]

As shown in FIG. 1, in the electrical test board for electronic parts of the present invention, the relay means 21-1 to 21-N are electrically insulated from each other, and the relay means 21 are provided.
-1 to 21-N is provided with a plurality of attachment / detachment portions 21a capable of freely attaching / detaching the short-circuiting means 22 for electrically short-circuiting any relay means 21-1 to 21-N.

Therefore, an electrical short circuit between any relay means 21-1 to 21-N is performed by attaching one end of the short-circuit means 22 to the attaching / detaching portion 21a of one relay means to be short-circuited,
By attaching the other end of the short-circuit means 22 to the attachment / detachment portion 21a of the other relay means, it can be freely performed. Further, if the short-circuiting means 22 is removed from the respective attachment / detachment portions 21a, the short-circuiting between the relay means is released and the open state is established.

Thus, the electrical test board for electronic parts according to the present invention can be applied to electronic parts in which signal terminals and power supply terminals are arranged at any position, as long as the appearance of terminals is the same. It can be handled by changing the wiring.
