Problems solved by technology
[0002] At present, traditional outdoor RRU feeder connectors generally use waterproof boxes for waterproofing. However, during the rainy season or in the season of high rain in summer, water is prone to accumulate in the waterproof box after a long time. Once water accumulates in the waterproof box, the water will It will leak into the joint, causing a standing wave alarm, and then causing a TD failure of the outdoor RRU

Embodiment Construction
[0015] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see figure 1 :
[0016] A heat-shrinkable sleeve waterproof structure for an outdoor RRU feeder connector, including a radio frequency module 1, a feeder connector 2 is provided on the radio frequency module 1, a feeder 3 is connected to the feeder connector 2, and the feeder connector 2 and the feeder 3 are connected to each other. A heat-shrinkable sleeve 4 is set at the connection. After the heat-shrinkable sleeve 4 is heated, the feeder joint 2 and part of the feeder 3 are completely wrapped and sealed in the heat-shrinkable sleeve 4. The upper and lower ends of the heat-shrinkable sleeve 4 are respectively wound twice. Above the first waterproof tape 5 and the second waterproof tape 6, the first waterproof tape 5 and the second waterproof tape 6 seal the upper and lower ends of the heat shrinkable sleeve 4 respectively, the upper and lower ends ...

The invention belongs to the technical field of waterproofing of RRU feeder connectors, and particularly relates to a heat-shrinkable sleeve tube waterproof structure of an outdoor RRU feeder connector. The heat-shrinkable sleeve tube waterproof structure comprises a radio frequency module, wherein a feeder connector is arranged on the radio frequency module, a feeder is connected with the feederconnector, a heat-shrinkable sleeve tube sleeves a joint of the feeder connector and the feeder, the heat-shrinkable sleeve tube completely wraps and encloses the feeder connector and part of the feeder inside the heat-shrinkable sleeve tube after being heated, the upper end of the heat-shrinkable sleeve tube is wound with twice or more turns of a first waterproof adhesive tape, the lower end of the heat-shrinkable sleeve tube is wound with twice or more turns of a second waterproof adhesive tape, the first waterproof adhesive tape seals the upper end of the heat-shrinkable sleeve tube, the second waterproof adhesive tape seals the lower end of the heat-shrinkable sleeve tube, and upper and lower ends of the first waterproof adhesive tape and the second waterproof adhesive tape are bundledby means of binding belts. The heat-shrinkable sleeve tube waterproof structure has the advantages that the feeder connector is wrapped by means of the first waterproof adhesive tape, the second waterproof adhesive tape and the heat-shrinkable sleeve tube so that the feeder connector is isolated from the outside, rainwater cannot enter the interior of the feeder connector, and the TD failure rateis greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of waterproofing of RRU feeder joints, in particular to a heat-shrinkable sleeve waterproof structure of an outdoor RRU feeder joint. Background technique [0002] At present, traditional outdoor RRU feeder connectors generally use waterproof boxes for waterproofing. However, during the rainy season or in the season of high rain in summer, water is prone to accumulate in the waterproof box after a long time. Once water accumulates in the waterproof box, the water will It will leak into the joint, causing a standing wave alarm, and then causing a TD fault on the outdoor RRU. Contents of the invention [0003] The purpose of the present invention is to provide a heat-shrinkable sleeve waterproof structure for an outdoor RRU feeder joint. [0004] The purpose of the present invention is achieved like this: [0005] A heat-shrinkable sleeve waterproof structure for an outdoor RRU feeder joint, including a ra...
