Abstract: A lightning protector assembly for telephone circuitry and the like includes a housing formed of a lower necked terminal section and an upper expanded grounding section. A component-mounting member is disposed within the housing for mounting a first pair of voltage limiting devices and a first pair of impedance devices. There are cavities provided in the lower part of the component-mounting member for receipt of a plurality of terminal contacts. The upper section has a pair of top recesses separated by a central bridging portion. Plug-in fuse holder units are disposed within the top recesses. A side ground contact is provided and includes an elongated horizontal member extending inside and across the width of the housing for connection to the first pair of voltage limiting means and a portion thereof extending externally of the housing.

Abstract: A sneak current protector for use with a communication circuit standard 110-type wiring block and block connector is disclosed. The protector includes a pair of fuses mounted between a first pair of resilient contact members and a second pair of stationary contact members. A female 110-type block connector attachment is provided at one end of the housing for attachment to the standard 110-type block connector and a complimentary shaped male attachment is provided at the opposite end of the housing for attachment to a patch cord-type terminal connector. Insulation displacement type contacts are provided at the male attachment for alternative connection to individual wires leading to the users equipment.
