Abstract
The utility model relates to a base station antenna feeder system, and discloses an antenna feeder joint protective box. According to the antenna feeder joint protective box, a water guiding pipe is arranged at the bottom part of gel in the antenna feeder joint protective box, the water accumulated in the protective box is discharged outside, thus the water accumulating problem in the antenna feeder joint protective box is solved, and the waterproof performance is strengthened, thereby promoting the reliability of the antenna feeder system, and guaranteeing the communication quality of the base station.
Description
Technical field
The utility model relates to the base station antenna feeder wire system, particularly the antenna feeder joint protection box.
Background technology
The antenna transmission system of base station refers to that base station BTS (base transceiver station) transfers to antenna with the electromagnetic wave of load information by feeder line, and the system that blazes abroad by antenna.Between the information transmission system, antenna plays the electromagnetic wave that will transmit in the feeder line and is converted to the electromagnetic wave that free space is propagated, or the electromagnetic wave that free space is propagated is converted to the electromagnetic effect of transmitting in the feeder line.In mobile communication network quality, the reliability of antenna transmission system accounts for whole base station system reliability 30%-50%.The feeder system problem of easy appearance is exactly connector poor sealing and intake, cause standing-wave ratio alarm, influences the base station and normally moves.Therefore waterproof technique is the key factor that antenna-feedback system must be considered.
The waterproof technique of antenna and feeder line itself, each big producer comparative maturities all substantially seldom produces drainage at present, but both junctions waterproof technique to lack be not the most ripe, drainage happens occasionally.
The joint waterproof technique mainly contains at present:
Technology one: adopt the adhesive waterproof tape wrapping, this is more traditional method, and advantage is that water resistance is relatively good.Shortcoming be construction process requirement than higher, cumbersome, the life-span of adhesive tape generally had only 5 years-8 years under outdoor environment, removed cumbersomely if the joint produces the fault adhesive waterproof tape, and can not reuse.
Technology two: adopt the antenna feeder joint protection box, this is to adopt many technology in recent years, and it has overcome a lot of shortcomings of adhesive waterproof tape, easily installs, removes reusable, and the life-span is long.Shortcoming be exactly water resistance be not fine.
The utility model content
The purpose of this utility model is to provide a kind of antenna feeder joint protection box, makes that the ponding problem in the antenna feeder joint protection box is solved, and strengthens water resistance, thereby promotes the reliability of antenna transmission system, guarantees the communication quality of base station.
For solving the problems of the technologies described above, execution mode of the present utility model provides a kind of antenna feeder joint protection box, has shell and reaches the gel that is used for inner sealing; Also comprise: aqueduct;
One end of described aqueduct is communicated with described gel bottom, and the other end extends to outside the described shell.
As a kind of preferred version, the cross section of described aqueduct is circular.
As a kind of preferred version, the diameter of described aqueduct is between 3 to 5 millimeters.
As a kind of preferred version, described aqueduct is the straight tube of polycarbonate material.
As a kind of preferred version, the upper surface of described shell and lower surface are respectively equipped with circular connection jaws; Described aqueduct is fixed in the connection jaws of described lower surface.
The utility model execution mode in terms of existing technologies; place aqueduct by the bottom of the gel in the antenna feeder joint protection box; ponding in the protection box is discharged into outside the protection box; make that the ponding problem in the antenna feeder joint protection box is solved; strengthen water resistance; thereby promote the reliability of antenna transmission system, guarantee the communication quality of base station.
Description of drawings
Fig. 1 is the structural representation of taking apart according to the antenna feeder joint protection box of the utility model one preferred embodiments;
Fig. 2 is the overall structure schematic diagram according to the antenna feeder joint protection box of the utility model one preferred embodiments.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing execution mode of the present utility model is explained in detail.Yet, persons of ordinary skill in the art may appreciate that in the utility model execution mode, in order to make the reader understand the application better many ins and outs have been proposed.But, even without these ins and outs with based on many variations and the modification of following execution mode, also can realize each claim of the application technical scheme required for protection.
First execution mode of the present utility model relates to a kind of antenna feeder joint protection box, improves on the basis of existing antenna feeder joint protection box, strengthens the water resistance of antenna feeder protection box.
See also illustrated in figures 1 and 2ly, existing antenna feeder joint protection box has shell 1 and is used for the gel 2 of inner sealing, and present embodiment has designed an aqueduct, and an end of this aqueduct 3 is communicated with gel 2 bottoms, and the other end extends to outside the shell 1.When the antenna feeder joint protection box was vertically installed, the ponding in the protection box was discharged better effects if.
The shell of antenna feeder joint protection box is the PC(Merlon) making of material, this material was 20 years in the following life-span of outdoor environment.Inside is a kind of sealing gel (polyurethane sealant), and this material can play the effect of filling sealing, cuts off antenna feeder joint and extraneous contacting.See also shown in Figure 1ly, in that these can accomplish to seal fully at ordinary times, well play waterproof effect.But the weather at strong wind and heavy rain; will have problems; strong wind can make feeder line shake; can produce the slit between feeder line and the gel like this; though gel can fill up the slit at short notice automatically, these short a few times in second just have water and permeate in the weather of heavy rain, accumulate throughout the year; have more ponding in the whole feeder head protection box, thereby influence the communication quality of base station.
A preferred version as present embodiment; can place a PC material in the gel bottom; cross section is that circular straight tube is as aqueduct; diameter is worked as ponding like this and is accumulated to a certain degree between 3-5mm, will all be discharged into outside the antenna feeder protection box by aqueduct; make that the ponding problem in the antenna feeder joint protection box is solved; strengthen water resistance, thereby promote the reliability of antenna transmission system, guarantee the current quality of base station.
In addition, because upper surface of outer cover and the lower surface of antenna feeder joint protection box are respectively equipped with circular connection jaws, therefore, for easy for installation, this aqueduct can be placed in the connection jaws of shell lower surface.
Persons of ordinary skill in the art may appreciate that above-mentioned execution mode is to realize specific embodiment of the utility model, and in actual applications, can do various changes to it in the form and details, and do not depart from spirit and scope of the present utility model.
