Embodiment

Below in conjunction with accompanying drawing of the present utility model, the technical scheme of the utility model embodiment is carried out clear, complete Description.

As shown in Figures 1 to 5, the utility model coupler includes the first main road joint 1, the second main road joint 2, is arranged on Cavity 3, U-shaped coupling assembly 4 and coupling aperture joint 5 between the first main road joint 1 and the second main road joint 2, institute State and coupler 31 is provided with cavity 3, the coupling assembly 4 is arranged in the coupler 31, the He of the first main road joint 1 Second main road joint 2 forms the main road inner wire 6 of a through type, and the coupling aperture joint 5 passes through the coupling assembly 4 and institute State main road inner wire 6 to be of coupled connections, the U-shaped design of coupling assembly of the present utility model, increase efficient coupling area, meanwhile, coupling The ingehious design of component and the main road transmission design of coaxial transmission cable architecture, make insertion loss of the transmission with very little of coupler And return loss, reduce the signal reflex of transmission.

Specifically, the first main road joint 1 described in the present embodiment and the second main road joint 2 are radio frequency connector structure, Wherein the first main road joint 1 is female, and the second main road joint 2 is male, and the inner wire of male and female is by straight-through main road Conductor 6 is formed, and main road inner wire 6 is separated by insulating medium layer respectively with the outer conductor of male, the outer conductor of female, and realization is penetrated Frequency signal transmits.Optionally, the first main road joint and the second main road joint can also be other signals in the utility model Transfer connector.

With reference to shown in Fig. 1 and Fig. 2, the cavity 3 is between the first main road joint 1 and the second main road joint 2 The rectangular configuration of protrusion, it is integrally formed with the outer conductor of the first main road joint 1 and the second main road joint 2, the chamber Body phase is in flat on the whole for forming a coupler 31, the coupler 31 in the one side of the main road inner wire, institute State the coaxial channel that coupler 31 is extended to where the main road inner wire 6.A positioning step is formed in the coupler 31 311。

With reference to shown in Fig. 2 and Fig. 5, it is in inverted U-shape structure that the coupling assembly 4 is overall, including the first support member 41, the Two support members 42 and coupling element 43, the coupling assembly are arranged in the coupler 31, first support member 41, coupling Element 43 and, the second support member 42 set gradually from inside to outside, first support member 41, the second support member 42 are E insulation materials Matter（Such as, PTFE, Ultem, Teflon etc.）, coupling element 43 is metal material, and two support members utilize its dielectric constant 2.1 Characteristic is adjusted to main road echo, is allowed to have preferable echoing characteristics in 700-2700MHz broadband range.

Further say, mounting hole 411, accordingly, the coupling element 43 are formed on the first U-shaped support member 41 Upper relevant position is also formed with coupling aperture 431, and the relevant position of the second support member 42 forms coupling slot 421, coupling element 43 After U-shaped the first support member 41 and the second support member 42, the coupling aperture 431 is coaxially disposed with the mounting hole 411, And coupling aperture 431 falls in the coupling slot 421.

As shown in Figure 2 and Figure 5, the outside of the second support member 42 also forms a step 422, and its bottom is also formed with out Mouth groove 423, the open slot 423 is used for passing through for main road inner wire 6, after installation, the step in the outside of the second support member 42 422 keep same horizontal line with the positioning step 311 of the coupler, and the two-arm of the coupling element 43 extends to described second The step 422 of support member 42, the two-arm of first support member 41 are resisted against on the positioning step 311 of the coupler 31, and Part is resisted against at the step 422 in the outside of the second support member 42, quilt between so described coupling element 43 and the cavity 3 First support member 41 and the second support member 42 are completely isolated.

As shown in Fig. 2 the coupling aperture joint 5 includes coupling inner wire 51, during installation, the coupling inner wire 51 is successively Through the mounting hole 411 on first support member 41, the coupling aperture 431 on coupling element 43, its terminal extends to described The coupling slot 421 of two support members 42, then it is fixed by screws on the cavity 3.So described coupling aperture joint 5 is with passing through The main road inner wire 6 of second support member 42 forms cross-couplings.

In the utility model, coupling aperture joint except completing to export coupled signal, meanwhile, the flange of joint is furnished with waterproof Circle, joint have had the function of waterproof cover concurrently simultaneously, and coupler main road joint uses Din-male and Din-female, Ke Yipei A variety of connected modes are connect, its Din-female joint is designed to water proof type through walls, but is used in the applicable cases such as waterproof cabinet.
