Abstract
The invention relates to a cavity coupler which comprises a rectangular coupler shell body, a rectangular cover plate and an insulating support strip. A cavity is formed between the rectangular coupler shell body and the rectangular cover plate, and a first connector, a second connector and a third connector are arranged on three side edges of the rectangular coupler shell body. One end of the main conductor of the insulating support strip is connected with the first connector, and the other end of the main conductor of the insulating support strip is connected the second connector. One end of a coupling conductor of the insulating support strip is connected with the third connector, and the other end of the coupling conductor of the insulating support strip is connected with a resistor. A positioning piece used for positioning the coupling conductor is arranged on the side edge of the rectangular coupler shell body. The cavity coupler is light in weight, and stable in performance.
Description
Technical field
The present invention relates to the mobile communication technology field, be specifically related to a kind of cavity coupler.
Background technology
At present China Mobile market has become the maximum Mobile Communications Market in the whole world and most important mobile communication product production base.But domestic mobile communication enterprise the capacity of R﹠D is also more weak generally, and the local supporting rate of the components and parts of mobile communication equipment and parts is also lower.The operation of mobile communication 3G has simultaneously arrived the critical period, and telecommunications system reform etc. also brings new business opportunity for it.The development of the communication technology is maked rapid progress, and the competition of coupler product is also more and more fierce, and the coupler product that is used for indoor distribution and base station is also more and more higher to the requirement of intermodulation index.
The following structure of the many employings of existing coupler on market: cavity inner wall is not emptied, and its inner surface is the plane; When die sinking die casting, use more material to cause that the product overall weight is heavier, cost is higher, and be all the substep hold-down screw in assembly connector, be difficult to guarantee the stability of product.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome deficiency of the prior art, provide a kind of chamber wall thinner, can one-time fix the novel cavity coupler of connector screwing.
Technical scheme: in order to solve the problems of the technologies described above, cavity coupler of the present invention, it comprises the rectangle fluid coupling shell, rectangle cover plate and insulating supporting bar, be cavity between this rectangle fluid coupling shell and rectangle cover plate, be provided with the first connector, the second connector and the 3rd connector on three sides of described rectangle fluid coupling shell; An end that is located at the leading body on described insulating supporting bar is connected with described the first connector, and the other end is connected with described the second connector; An end that is located at the coupling conductors on described insulating supporting bar is connected with described the 3rd connector, and the other end is connected with resistance; Be provided with one on the side of described rectangle fluid coupling shell described coupling conductors is positioned the keeper at described cavity middle part.
Described leading body and coupling conductors be arranged in parallel.
Described leading body and coupling conductors and described the first connector, the second connector, the 3rd connector and resistance welded are fixed.
Described insulating supporting bar is located at described cavity inside.
Described rectangle fluid coupling shell is the aluminium section bar thin-wall construction.
Four screws separately on described the first connector, the second connector and the 3rd connector are all to be located by connecting with described rectangle fluid coupling shell the disposable while.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: the inwall of this coupler cavity is thinner, has saved the use amount of aluminium section bar, and the weight of whole cavity is alleviated greatly; Simultaneously, the connector on this cavity adopts disposable method of fixing simultaneously four screws, has greatly improved the stability of product.

Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As Fig. 1, Fig. 2 and shown in Figure 3, cavity coupler of the present invention, it comprises rectangle fluid coupling shell 1, rectangle cover plate 2 and insulating supporting bar 3, this insulating supporting bar 3 is more than two, be cavity 4 between described rectangle fluid coupling shell 1 and rectangle cover plate 2, be provided with the first connector 5, the second connector 6 and the 3rd connector 7 on three sides of described rectangle fluid coupling shell 1; Described the first connector 5, the second connector 6 and the 3rd connector 7 are N connector; An end that is located at the leading body 8 on described insulating supporting bar 3 is connected with described the first connector 5, and the other end is connected with described the second connector 6; An end that is located at the coupling conductors 9 on described insulating supporting bar 3 is connected with described the 3rd connector 7, and the other end is connected with resistance 10; Be provided with one on the side of described rectangle fluid coupling shell 1 described coupling conductors 9 is positioned the keeper 11 at described cavity 4 middle parts; Described leading body 8 be arranged in parallel with coupling conductors 9; Described leading body 8 and coupling conductors 9 are welded and fixed with described the first connector 5, the second connector 6, the 3rd connector 7 and resistance 10; Described insulating supporting bar 3 is located at described cavity 4 inside; Described rectangle fluid coupling shell 1 is the aluminium section bar thin-wall construction; Four screws 12 separately on described the first connector 5, the second connector 6 and the 3rd connector 7 are all to be located by connecting with described rectangle fluid coupling shell 1 the disposable while, when the location, use special orientation tool, simultaneously four screw fastenings, can improve like this stability of product.The inwall of cavity of the present invention is thinner, has saved the use amount of aluminium section bar, and the weight of whole cavity is alleviated greatly; Simultaneously, the connector on this cavity adopts disposable method of fixing simultaneously four screws, has greatly improved the stability of product.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
