Description
Technical field
The invention belongs to RRU feeder head waterproof technique field, the heat-shrinkable T bush for refering in particular to a kind of outdoor RRU feeder head is anti-
Water-bound.
Background technique
Currently, traditional outdoor RRU feeder head uses compartment generally to carry out waterproof, but plum rain season or
When summer rainwater high-incidence season, over time after be easy to produce ponding in compartment, after compartment internal water accumulation, ponding is just
It can leak into connector, standing wave is caused to alert, and then outdoor RRU is caused TD failure occur.
Summary of the invention
The object of the present invention is to provide a kind of heat-shrinkable T bush waterproof constructions of outdoor RRU feeder head.
The object of the present invention is achieved like this:
A kind of heat-shrinkable T bush waterproof construction of outdoor RRU feeder head, including radio-frequency module, radio-frequency module are equipped with feeder line
Connector is connected with feeder line on feeder head, and the junction between the feeder head and feeder line is set with heat-shrinkable T bush, pyrocondensation
Casing is fully wrapped around by feeder head and part feeder line after being heated and is enclosed in heat-shrinkable T bush, the upper and lower side point of heat-shrinkable T bush
It is not wound with the first adhesive waterproof tape and the second adhesive waterproof tape of two circles or more, the first adhesive waterproof tape and the second adhesive waterproof tape seal respectively
The upper and lower side of the upper and lower side of dead heat-shrinkable T bush, the first adhesive waterproof tape and the second adhesive waterproof tape is bundled by band.
In the above-mentioned technical solutions, it is set with outside first adhesive waterproof tape, the second adhesive waterproof tape and heat-shrinkable T bush
Compartment, compartment include upper cartridge body and lower box body interconnected, and the bottom surface of lower box body is equipped with leakage hole.
In the above-mentioned technical solutions, the bottom of the lower box body is pyramidal structure, and leakage hole is arranged on tapered surface.
In the above-mentioned technical solutions, the upper end of the lower end and lower box body of the upper cartridge body is provided with flange, upper box
Fixation is bolted between the flange of upper cartridge body and the flange of lower box body after fastening in body and lower box body.
In the above-mentioned technical solutions, reinforcing rib is respectively provided on the outer surface of the upper cartridge body and lower box body.
The present invention is prominent and beneficial compared with prior art to be had the technical effect that
1, the present invention by the first adhesive waterproof tape, the second adhesive waterproof tape and heat-shrinkable T bush by feeder head package make its with
Isolation substantially reduces TD failure rate so that rainwater cannot be introduced into feeder head.
2, the present invention is protected the first adhesive waterproof tape, the second adhesive waterproof tape and heat-shrinkable T bush by the way that compartment is arranged
Come, compartment forms first of waterproof construction, and it is anti-that the first adhesive waterproof tape, the second adhesive waterproof tape and heat-shrinkable T bush form second
Water-bound, dual waterproof construction can realize maximum waterproofing protection to feeder head.
3, structure of the invention is simple, easy for construction, and construction cost greatly reduces.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the invention.
Specific embodiment
With specific embodiment, the invention will be further described with reference to the accompanying drawing, referring to Fig. 1:
A kind of heat-shrinkable T bush waterproof construction of outdoor RRU feeder head, including radio-frequency module 1, radio-frequency module 1 are equipped with feedback
Wire terminal 2 is connected with feeder line 3 on feeder head 2, and the junction between the feeder head 2 and feeder line 3 is set with thermal shrinkable sleeve
Pipe 4, heat-shrinkable T bush 4 is fully wrapped around by feeder head 2 and part feeder line 3 after being heated and is enclosed in heat-shrinkable T bush 4, thermal shrinkable sleeve
The upper and lower side of pipe 4 is wound with the first adhesive waterproof tape 5 and the second adhesive waterproof tape 6 of two circles or more, the first adhesive waterproof tape 5 and respectively
Two adhesive waterproof tapes 6 shut the upper and lower side of heat-shrinkable T bush 4 respectively, and the upper and lower side of the first adhesive waterproof tape 5 and the second adhesive waterproof tape 6 is logical
The binding of band 7 to be crossed, feeder head 2 is isolated from the outside world, rainwater will not leak into feeder head 2, TD failure rate is substantially reduced,
And this waterproof construction construction is simple, construction cost are low.
Compartment 8, compartment 8 are set with outside above-mentioned the first adhesive waterproof tape 5, the second adhesive waterproof tape 6 and heat-shrinkable T bush 4
Including upper cartridge body 8a interconnected and lower box body 8b, the bottom surface of lower box body 8b is equipped with leakage hole 9, and the bottom of lower box body 8b is
Pyramidal structure, leakage hole 9 are arranged on tapered surface, once rainwater enters compartment 8, rainwater leaks out outward from leakage hole 9.
The upper end of the lower end and lower box body 8b of above-mentioned upper cartridge body 8a is provided with flange 10,11, and upper cartridge body 8a is under
Box body 8b is connected and fixed between the flange 10 of upper cartridge body 8a and the flange 11 of lower box body 8b by bolt 12 after fastening.
