The level monitor terminal D protrudes from the protruding hole E of the case A, and an F-type connector G connected to the coaxial cable F is connected to the RF output terminal C as shown in FIG. The unit B is wired into the subscriber premises via the coaxial cable F. 9 and 10, H is a wiring tray, and J is a cover of the device case. As shown in FIG. 11C, the F-type connector G can be fastened to the RF output terminal C and the output level monitor terminal D when rotated in the direction of the arrow, and can be detached from the terminals C and D when rotated reversely. .

The conventional optical receiver has the following problems.
(1) To remove the RF unit B from the device case A for maintenance, inspection, repair, replacement, etc., the trouble of having to remove the coaxial cable F by removing the F-type connector G from the RF output terminal C is required. is there. In order to remove the coaxial cable F, it is necessary to remove the tape taped around the outer periphery of the F-type connector G, remove the waterproof boot, remove the F-type connector G, and the like. There is.
(2) As shown in FIGS. 11A to 11C, there is a gap K between the protruding hole E of the device case A and the RF output terminal C and the output level monitor terminal D inserted into the protruding hole E. When the mold connector G is not connected, dust and rainwater may enter the device case A through the gap K, and the processing is troublesome in terms of dustproofing and waterproofing.

  The object of the present invention is to remove the F-type connector G from the RF output terminal C when the RF unit B is removed from the device case A, and the projecting hole E of the case A and the RF output terminal C inserted therein, the output There is no gap K between the level monitor terminal D and a connecting tool mounting structure that prevents dust and rainwater from entering the case A without connecting the F-type connector G, and the mounting structure. It is providing the communication apparatus provided with the connection tool.
