Claims

[Claims for Utility Model Registration] (1) In a protector comprising a coaxial cable coil inserted into a line between an external line terminal and an internal line terminal for transmitting signals, the coaxial cable coil is placed on the circumferential surface of a bobbin made of an insulating material. The central conductor of the coaxial cable coil is formed by winding, and the central conductor of the coaxial cable coil is protruded from both ends of the cable coil along with its insulating coating by a required length to connect with the line, and the mesh-like outer conductor of the coaxial cable coil is protruded from the insulating coating. A safety device characterized by having a twisted wire drawn out from the base and connected to the ground. (2) In a protector consisting of a coaxial cable coil inserted into the line between the external line terminal and internal line terminal for transmitting signals, the coaxial cable coil is bound with a binding wire as a coreless coil, and the center of the coaxial cable is The conductor along with its insulating coating is protruded from both ends of the coaxial cable for a required length to connect with the above line,
A protector characterized in that the mesh-like outer conductor of the coaxial cable coil is pulled out from the protruding base of the insulating coating and twisted into wires for ground connection.
