なる。Problems to be Solved by the Invention However, since the above protector has a structure in which both the office side and the coaxial cable on the inside of the house are introduced and led out while being bent to the base bottom surface, the protector largely bypasses both cables which are limited in bending. There is a disadvantage that it must be bent and wired.Both cables must be concentrated in a limited space on the bottom of the base, occupying a lot of cable wiring space, and it is extremely troublesome to connect both coaxial cables to connectors. This is a complicated operation.

を招かない。Advantageous Effects of the Invention As described above, according to the present invention, a protector is usually used by using a connector connection port on the office side and inside the house, which protrudes in opposite directions from caps at both ends of a cylindrical body serving as a protector body. The installed coaxial cables on the opposite side of the office and on the inside of the house can be guided to the respective end surfaces of the cylindrical body, respectively, so that smooth connection and wiring can be performed in the cable extending direction, and the connector connection to each of the two coaxial cables can be performed. In addition, the work of connecting the protector becomes remarkably easy, and the cable wiring does not become complicated as in the related art.

減できる。Also, as described above, the coaxial cable on the inside of the house is connected with a connector connection port protruding from one end cap of the cylindrical body as the connector body, and the office side coaxial cable is connected with a connector connection port protruding from the other end cap of the same cylindrical body. In this connection, the coaxial cable and the protector tube are connected in the same way, minimizing the wiring space for the erection cable and arranging the connector on the conventional protector base. Protective device such as a protector that connects and guides both coaxial cables to the bottom of the base does not increase the outer shape or width of the protector, and can reduce the body of the protector body as much as possible, and the installation space Can be reduced.
