In order to prevent the Fiber Optic Splice Closure from entering the water, preventing exposure to aging and prolonging the service life, it is necessary to do maintenance work so that the incidence of problems can be effectively reduced.

There are a few things to keep in mind when maintaining the cable connector box: After each rain, the cable connector box is burned down, and the repair work will be very large. In fact, the cable connector box is easy to enter the water because the space inside the cable connector box is too small, there is no extra space to place the waterproof bend, and the 35mm power supply line is fixed with a plastic expansion tube, so that the waterproof measures are not in place, and the rain will follow. The cable is left in the connector box, and the terminal block is wetted. Because the gap between the terminals is small and the insulation effect is not good, it is easy to short-circuit.

In addition, the design of the cable connector box itself has surrounding heat dissipation holes and wiring holes, and the design originally used for the heat dissipation wiring becomes a defect at this time, and the cable connector box becomes easier to enter the water in rainy days. In this case, it is necessary to regularly check the maintenance cable junction box, press the wires in the cable connector box in time, and replace the damaged or aged wires in time. If there is not enough space, install the connection box in time to prevent too much internal wiring. The space is too small.
