Description
Technical field:
The utility model relates to communication technical field, particularly relates to a kind of communication cavity component.
Background technology:
Cavity type power divider a kind ofly a road input signal energy is divided into two-way or multiple-channel output is equal or the device of unequal energy, also conversely multiple signals energy can be synthesized a road and export, now also can be described as mixer, be mainly used in network service.Power splitter is a kind of comparatively general passive device, and its function is the signal of input is separated equal or two-way not etc. or multiple signals, plays the effect of power division.Now common in the application mainly two power splitters, three power splitters, four power splitters.It is large that chamber power divider bears power with it again, the feature that insertion loss is little, and it is mainly used in: 1,800MHz-2500MHz frequency band two, three, four cavity series power splitter, is applied to GSM/CDMA/PHS/WLAN in-door covering engineering; 2,1700MHz-2500MHz frequency band two, three, four cavity series power splitter, is applied to PHS/WLAN in-door covering engineering; 3, micro-band two, three power splitter used in 800MHz-1200MHz/1600MHz-2000MHz frequency band small device.But, chamber power divider in the market installs inconvenience and degree of protection is not high, affect the useful life of product and the front elevational sectional of original cavity and interface, rear end are all squares of 24mm × 24mm, the covering of high-frequency, wide band signals cannot be met, merit proportion by subtraction poor performance.
Utility model content:
In order to solve the problem, the utility model provides that a kind of structure is simple, volume is little, waterproof, easy for installation, has the feature of low-loss, high power, wide-band, can improve the technical scheme of merit proportion by subtraction performance simultaneously:
A kind of communication cavity component, relate to a kind of chamber power divider, mainly comprise metallic cavity, connector, contact pin, metallic cavity front end is thick, and rear end is thin, metallic cavity front-end and back-end are equipped with three ports, metallic cavity inside is provided with metal conductive bar, Metallic rod, and metallic conduction nose is thick, rear end is thin, correspondingly with metallic cavity arranges, contact pin is positioned at connector and is interconnected with Metallic rod, in the middle part of the connection metal bar of metal conductive bar one end.
As preferably, the contact rod head and the tail that metal conductive bar is increased progressively by least two joint diameter step formulas connect to form, and in the middle part of the front end connection metal bar of metal conductive bar, the rear end of metal conductive bar connects the contact pin being positioned at metallic cavity rear end.
As preferably, metallic cavity front-end cross-sectional view is long is 30mm, the wide square for 30mm, metallic cavity cross sectional rear end face for long be 20mm, wide is the square of 20mm.
As preferably, metallic cavity both sides also arrange installed part symmetrical between two respectively, and installed part arranges four, and installed part is for being circular hollow structure.
As preferably, connector is connected with port threads by watertight composition.
The beneficial effects of the utility model are:
(1) traditional power splitter cross-sectional area strengthens by the utility model, also meets the covering to broadband signal, can reduce the wastage the while of meeting high-power.
(2) the utility model arranges installed part in metallic cavity both sides, is convenient to firm installation, can prevent damage metallic cavity shell simultaneously.
(3) the utility model is threaded by watertight composition between connector with port, prevents steam from entering metallic cavity inside and causes damaging metal conductive bar, have good waterproof action.
(4) the utility model all arranges three connectors in metallic cavity front and back end, can improve merit proportion by subtraction performance.
Accompanying drawing illustrates:
Fig. 1 is Integral connection structure figure of the present utility model;
Fig. 2 is left view of the present utility model.
Embodiment:
