Claims

[Scope of utility model registration request]

A pair of wires that connect telephone cables from the telephone office.
Connecting the outside line terminal and a pair of indoor line terminals connected to the subscriber's terminal equipment with fuses housed in respective fuse tubes, and connecting two lightning arresters in series between the pair of indoor line terminals, This is a subscriber protector housing a safety circuit formed by connecting the connecting points of the two lightning arresters to the ground, and the bottom is made by bending one end of a rectangular plate made of an insulating material at a substantially right angle. The vertical face plate of the base plate formed with the face plate and the vertical face plate includes the pair of outdoor line terminals, the fuse tube support piece, the lightning arrester holding piece, the indoor line terminal, and one ground air line terminal, and At least two screws are inserted through which the outdoor wires, indoor wires, and ground air wires are inserted, and the screws are screwed into the screw holes in the switch box opened in the outer wall of the building. A hole is provided, and a convex strip is formed on the outer peripheral end surface of the end surface of the rectangular plate forming the vertical face plate, excluding the surface that contacts the bottom plate, and a rubber material is formed around the surface where the vertical face plate contacts the outer wall surface. A substrate part is made of synthetic resin and is formed into a hollow rectangular cylinder shape with an open bottom part and a back part, and the back part is 1. A subscriber safety device for a switch box, comprising a cover provided around an opening end surface with a groove that engages with a protrusion provided around an end surface of the vertical face plate of the base plate.
