Problems solved by technology

However, in the case of a case made of metal, since the case is a conductor, it is necessary to make the insulation distance between the case and the internal circuit of the SPD larger than that between the case made of insulating material and the internal circuit of the SPD. Insulation distance, and thus the LAN SPD itself becomes large and cost-increased

Abstract

An isolator 10 is formed with an isolation transformer 13 that blocks an abnormal voltage entering from a communication line 30 and protects a protection target device 40. A pulse transformer 43 in the device 40 includes a primary winding 43a connected to a secondary winding 13b of the transformer 13 and a secondary winding 43b connected to an inner circuit. A medium tap of the primary winding 43a is grounded through an inner capacitance Ci of the device 40. A parasitic capacitance Cs between the primary winding 13a and the secondary winding 13b of the transformer 13 and the inner capacitance Ci are connected in series, an abnormal voltage is divided by the capacitance Cs and the capacitance Ci, and a capacitance value of the capacitance Cs is set such that the divided voltage of the capacitance Ci is equal to or below a predetermined value.

Description

technical field [0001] The present invention relates to a communication line isolator (which is called, for example, a surge protective device for LAN (hereinafter referred to as "SPD")) arranged to intervene in a communication line to protect the corresponding Optical network unit (hereinafter referred to as "ONU"), home gateway (hereinafter referred to as "HGW"), personal computer (hereinafter referred to as "PC") including communication lines connected to lines such as local area network (hereinafter referred to as "LAN") ) and a modem communication device to the target device. In particular, the present invention relates to an insulating type communication line isolator (such as an insulating type LAN SPD) having high voltage resistance. Background technique [0002] In order to protect a communication device corresponding to a protection target device from abnormal voltage or current such as a lightning surge entering from a power line, a communication line, or a groun...
