BOARD FOR SURGE ABSORBING DEVICE OF COMMUNICATION LINE

摘要

A board for surge absorbing devices of a communication line in which the mouting area of a group of surge absorbing elements is made less and an improvement of the dielectric strength of the holding board is intended too, by providing a predetermined holding board apart from boards for devices in apparatus connected to the communication line. According to this invention, the mounting area of the group of the surge absorbing elements can be decreased to about one half or less of conventional ones. Since the distances between wiring patterns on the holding board can be shortened if the dielectric strength of the holding board is fixed, the area of the holding board can be further decreased.
