Abstract

A line protector for a communications circuit comprises a module containing a pair of carbon blocks that provide an air gap in a shunt circuit for grounding high voltage transients. In an overcurrent condition in that shunt circuit, a solder element melts causing contacts in an overcurrent shunt circuit to engage and ground the line. The protector also has an overcurrent responsive mechanism comprising a heat coil for melting the solder element. The heat coil is wound on a bobbin that constitutes one of the contacts in the overcurrent shunt circuit. The bobbin is telescoped with a pin that abuts a cap that engages one of the carbon blocks. The solder element secures the bobbin contact against movement relative to the pin except upon melting of the solder element.
