The invention relates to a connector protective box, in particular relates to an optical cable antenna feeder cable connector protective box, and discloses a weatherproof protective device of a communication antenna feeder connector. The protective device comprises a casing body the two ends of which are provided with antenna outlets, a left locking device and a right locking device; the casing body comprises an upper casing body and a lower casing body which are mutually covered; the upper cover and the lower cover comprises an upper bulge and a lower bulge which are formed by connecting two semi-circle barrels front and back; the upper bulge and the lower bulge extend to two sides to form a fastening outer side; the right locking device is matched with the fastening outer side the upper part and the lower part of the right side of which are relative; the left locking device is matched with the fastening outer side the upper part and the lower part of the right side of which are relative; and the upper shell and the lower shell are locked in a closing state. The protective device provided by the invention can be completely sealed in no need of using a hinge and metal fittings, has strong weather resistance, can be used repeatedly for more times, and has low cost and is simple in operation.
Description
technical field [0001] The invention relates to a joint protection box, in particular to an optical cable antenna feeder joint protection box. Background technique [0002] The communication antenna feeder is an important part of microwave relay communication. The antenna at the transmitting end plays the role of converting the electromagnetic wave transmitted in the feeder into the electromagnetic wave propagated in free space, and the antenna at the receiving end plays the role of converting the electromagnetic wave the role of electromagnetic waves. In the microwave relay communication circuit of the multi-channel shared antenna and feeder system, the technical performance and quality index of the antenna and feeder system directly affect the communication quality. The normal operation of the antenna and feeder system can not only expand the coverage area, reduce blind spots, and improve the coverage rate, but also reduce interference, crosstalk, and drop-off rate, so as...
