Abstract
The utility model provides an it has along its axially extended bar hole of permeating water to distribute on the periphery that antenna protection end cover is equipped with the mounting hole that more than one was equipped with the dust plug that permeates water on the end cover, and the dust plug's that permeates water center is equipped with a centre bore, and it has the dustproof hole of permeating water to distribute around this centre bore, is equipped with a cylindric boss at the dust plug that permeates water towards the inside one side of antenna, and this boss is hollow structure and corresponds the intercommunication with the centre bore, at this boss. Compare with the material of end cover itself, process the aperture on the dust plug that permeates water more easily, thereby it improves dustproof effect to do benefit to the diameter in the dustproof hole that reduces to permeate water. Set up to the outstanding boss in antenna inside to set up the bar hole of permeating water on the boss, increased the drainage area, improve the efficiency of drainage, and difficult the jam.
Description
Technical field
The utility model relates to the end cap of antenna for base station cover, specifically a kind of antenna protection end cap.
Background technology
Existing antenna for base station degree of protection is lower, under severe environment for use, as heavy rain, sand and dust, the harmful ponding of the inner very possible generation of radome affects antenna performance, if simple antenna end cap reduces permeable hole diameter, the risk of blocking can be there is under dust and sand weather.Therefore, under guarantee reliability prerequisite, higher degree of protection becomes antenna for base station development trend already.At present, the antenna for base station that degree of protection reaches IP55 is relatively less, and design not only fully can not ensure that the solid foreign materials that diameter is less than 1mm cannot enter in antenna, and the dust-proof pore volume of antenna is easily blocked, and inner ponding is more difficult discharges completely, there is risk.
Utility model content
Technical problem to be solved in the utility model overcomes above-mentioned defect, provide a kind of anti-dust performance good and be easy to permeable draining antenna protection end cap.
The utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of antenna protection end cap, end cap is provided with the installing hole that more than is equipped with permeable dust plug, the center of permeable dust plug is provided with a centre bore, the surrounding of this centre bore is distributed with permeable dust-proof hole, a columned boss is provided with towards the one side of inner antenna at permeable dust plug, this boss is hollow structure and correspondingly with centre bore is communicated with, and the periphery of this boss is distributed with along its axially extended bar shaped permeable hole.
The diameter in described permeable dust-proof hole is less than 1mm.
The diameter of described centre bore is 3-6mm.
The diameter of described centre bore is 4mm.
The width of described bar shaped permeable hole is less than 1mm.
The surrounding of described permeable dust plug is provided with buckle, and on end cap, the inwall of installing hole is provided with and the draw-in groove be clasped.
The beneficial effects of the utility model are: compared with the material of end cap itself, easier machining small on permeable dust plug, are beneficial to the diameter thus raising dust-proof effect that reduce permeable dust-proof hole.Except permeable dust-proof hole, be also provided with a boss outstanding to inner antenna, and on boss, arrange bar shaped permeable hole, thus increase drainage area, improve the efficiency of draining, and not easily block, degree of protection can reach IP55.This structure can clean positions such as permeable dust-proof holes after dismantling permeable dust plug easily, convenient and reliable.

Embodiment
Execution mode of the present utility model is illustrated below in conjunction with accompanying drawing.
As described in Figure 1, antenna protection end cap of the present utility model is provided with more than one installing hole, is all equipped with in the embodiment shown in permeable dust plug 1, Fig. 1 and is provided with 5 permeable dust plugs along end cap edge in each installing hole.The structure of permeable dust plug 1 as shown in Figure 2,3, permeable dust plug 1 surrounding be provided with buckle 4, buckle in illustrated embodiment has a bending elastomeric element, this elastomeric element is provided with the chuck for being fixed, this buckle matches with the draw-in groove of installing hole inwall on end cap, to realize the fast assembling-disassembling of permeable dust plug.Be provided with a centre bore 2 at the center of permeable dust plug 1, the surrounding of this centre bore is distributed with permeable dust-proof hole 3.According to the requirement of degree of protection, during degree of protection IP55, the diameter in permeable dust-proof hole 3 is less than 1mm, to ensure that the solid foreign materials that diameter is less than 1mm cannot enter in antenna.Centre bore 2 is as the main thoroughfare of draining, and its diameter is greater than permeable dust-proof hole 3, is generally 3-6mm, is preferably 4mm.A columned boss 5 is provided with towards the one side of inner antenna at permeable dust plug 1.This boss is hollow structure, and is positioned at the center of permeable dust plug, its opening connected with the body of permeable dust plug 1, and correspondingly with centre bore 2 is communicated with, and another side is closed, to block centre bore 2 completely.The periphery of this boss 5 is distributed with along its axially extended bar shaped permeable hole 6, four bar shaped permeable holes 6 are provided with in embodiment shown in Fig. 3, the width of bar shaped permeable hole 6 is arranged according to the requirement of degree of protection equally, and during degree of protection IP55, the width of bar shaped permeable hole 6 is less than 1mm.By the centre bore 2 that arranges with add drainage area to the bar shaped permeable hole 6 that inner antenna extends, ponding is flowed out fast by the centre bore that diameter is larger smoothly, and the efficiency of raising draining, and not easily blocks.
