[0019] It should be noted that since there is no protective device after the existing fiber optic patch cord is connected, dust is easily introduced into the connection, and long-term use will cause damage to the connection of the fiber optic patch cord, thereby affecting the signal transmission rate and increasing the failure rate. In addition, the fiber optic patch cord sometimes needs to pass through a hole during installation, which makes it easy for external dust to enter the fiber optic patch cord connector. Therefore, in order to solve the problem that there is no protective device after the existing fiber optic patch cord is connected, dust is easily introduced into the connection, and long-term use will cause damage to the connection of the fiber optic patch cord, thereby affecting the signal transmission rate and increasing the failure rate. In addition, the fiber optic patch cord has a hole during installation.

When the mark 11 moves completely to the bottom of the observation port, it means that the protective cover 6 is installed in place on the outer wall of the wiring tube 2.

[0022] In a further preferred embodiment of the present invention, Figure 1 As shown, a glass 10 is fixedly connected to the inner wall of the observation port.

[0023] In this embodiment, the observation port is sealed by glass 10 to prevent foreign matter from entering the protective cover 6 .
