As can be seen from this figure, the coaxial cable 45 is wired diagonally, so that the wiring device B and the two TV connectors A are connected to each other. Wiring equipment B
Alternatively, the TV connector A does not interfere with the wiring, and there is no need to forcibly bend the coaxial cable 45.

[Effects of the Invention] The present invention provides a method for shielding a terminal block made of an insulating material and provided with a terminal fitting for connecting a signal line of a coaxial cable so that the connection direction of the coaxial cable is diagonal to the protruding base of the cover. Since it is provided on the side of the case, even if the shield case has a single module size, there is enough space on the side of the shield case to install the terminal block that connects and fixes the coaxial cable. It corresponds to the dimensions of one module that can be installed three times in a row on the mounting frame of the wiring device, and a pair of locking protrusions are formed on both sides of the cover to be locked to the mounting frame, so that other parts can be attached to the mounting frame. When connecting a coaxial cable with a wiring device, the adjacent wiring device does not get in the way when connecting the coaxial cable to the terminal fitting of the terminal block, so the coaxial cable can be easily connected without having to forcefully bend it. This is especially effective because the coaxial cable itself is not flexible, and since the coaxial cable to be connected does not get in the way, other wiring devices can be installed adjacently in the same mounting frame, so the mounting frame can be used effectively. For example, it is also possible to install a power outlet for a TV receiver next to it. In addition, since it can be attached to the mounting frame, it has the effect of allowing existing plates to be used selectively according to the interior decoration. Since it is equipped with a connection means for coaxial plugs and F-type plug connections, which consists of a receiving blade metal fitting,
The effect is that you can easily connect from the TV side.
