Abstract
A line protector for a communications circuit provides at least overvoltage protection. The overvoltage protection is obtained through a solid state arrester such as a diode. As the solid state arrester is not as long as the carbon electrode type or gas tube arrester which it replaces, the line protector includes a hollow conductive pedestal. The hollow conductive pedestal, which may be a deep drawn cup, provides sufficient flexibility to avoid damaging the arrester when the line protector is subjected to a drop test. The end of the pedestal adjacent to the solid state arrester is shaped to receive one electrode of the arrester, while the other end of the pedestal is shaped to provide a good contact to the grounding circuit of the protector.
