Abstract

The invention discloses a coupler and relates to the technical field of communication materials. The coupler comprises a shell, an inner conductor is arranged in the center of the shell, and the widths of all portions of the inner conductor are consistent. The coupler further comprises supporting blocks of hollow structures, the inner conductor is sleeved with a coupling tube, and the two ends of the coupling tube are inserted into the supporting blocks, so that a certain gap is formed between the coupling tube and the inner conductor. Due to the structure, not only is the problem of machining difficulty solved, but also the width of the working frequency is increased, and an input port and an output port can be exchanged.

Description

Coupler

Technical field

The present invention relates to communication material technology field, be specifically related to a kind of coupler.

Background technology

Coupler is that a class can make the signal in transmission be coupled in the coupled zone of ad hoc structure, and the device of reallocating, coupler of the prior art adopts impedance transformation line 6 and probe to be coupled, as shown in Figure 1, in housing, adopt 1/4 impedance transformation line 6, be step-like structure, its weak point is, because overall size is long and thinner, therefore increased difficulty of processing, in addition, adopt probe to be coupled, its operating frequency is narrow, be only 800-2500MHz, the more important thing is, in the time that the return loss of the input port of product meets user demand, the non-constant of return loss meeting of delivery outlet, and product in use can not be put upside down input port and delivery outlet, otherwise can cause total reflection power to burn whole system.

Summary of the invention

In order to solve the problems of the technologies described above, the invention provides a kind of coupler, by changing the structure of inner wire, shorten the length of inner wire, and increased the width of operating frequency, input port and delivery outlet can be exchanged mutually.

Technical scheme of the present invention is as follows:

Coupler, comprise housing, be laid with an inner wire at the center of described housing, on described inner wire, the width at each position is consistent, be socketed with the back-up block of insulating material in the both ends of the surface of described inner wire, described back-up block is hollow structure, has the tube coupling of consistency of thickness in the outer cover of described inner wire, insert on described back-up block at the two ends of described tube coupling, makes to form between tube coupling and inner wire certain gap.

As preferably, the square tube that described inner wire is metal material or pipe.

Further, the material of described back-up block is polytetrafluoroethylene.

Further, described back-up block is provided with multilayer inner ring, and described tube coupling can join with the inner ring of different levels according to actual needs, adjusts the space between described inner wire.

Beneficial effect: by above technical scheme, the present invention has the following advantages:

1, owing to having changed the structure of inner wire, therefore meeting under the situation of transmission demand, its length shortened more to some extent, had saved material; 2, inner wire, because the external diameter at each position is identical, is therefore processed simple and easy; 3, widened operating frequency, the 800-2500MHz that can give from prior art becomes 500-3000MHz; 4, promoted the input port of product and the return loss of delivery outlet, and this structure can also arbitrarily put upside down input port and delivery outlet, on system without any impact.

Brief description of the drawings

In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the sectional structure schematic diagram of coupler mentioned in background technology of the present invention;

Fig. 2 is the disclosed coupler sectional structure of embodiment of the present invention schematic diagram.

Numeral and the represented corresponding component title of letter in figure:

1, back-up block; 2, joint; 3, tube coupling; 4, housing; 5, inner wire; 6, impedance transformation line.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

Embodiment 1

Coupler, in conjunction with Fig. 2, comprises housing 4, be laid with an inner wire 5 at the center of described housing 4, the pipe that inner wire 5 is metal material, on described inner wire 5, the width at each position is consistent, be that described inner wire 5 is a straight tube, as shown in Figure 1, available technology adopting 1/4 impedance transformation line, its processing mode difficulty is larger, and adopt straight tube to greatly reduce difficulty of processing, and in addition, the also corresponding shortening of the length of required pipe, its length is about 1/4 of impedance transformation line, has saved material.

Be socketed with the back-up block 1 of insulating material in the both ends of the surface of described inner wire 5, described back-up block 1 is hollow structure, there is the tube coupling 3 of consistency of thickness in the outer cover of described inner wire 5, insert on described back-up block 1 at the two ends of described tube coupling 3, make to form certain gap between tube coupling 3 and inner wire 5, because tube coupling 3 and inner wire 5 are concentric structure, and centre utilizes back-up block 1 to separate, there is certain gap, and back-up block 1 is insulating material, therefore the two does not contact mutually, can avoid short circuit phenomenon.

In use, when back-up block 1 adopts the material of polytetrafluoroethylene, not only cost is low, and stability is very good.

A joint 2 is installed on the diametric plane of described housing 4, by adjusting the position of joint 2 on diametric plane, can be regulated coupling value, especially when the input port on coupler with delivery outlet to timing, convenient adjustment at any time, has very strong flexibility.

Embodiment 2

All the other are identical with embodiment 1, and institute's difference is, the square tube that described inner wire 5 is metal material, and the square tube of the unified external diameter of use, it is processed more for convenience; By be provided with multilayer inner ring on described back-up block 1, described tube coupling 3 can join with the inner ring of different levels according to actual needs, adjust the space between described inner wire 5, it is mainly in order to adjust the clearance height between tube coupling 3 and inner wire 5, to meet the user demand under different situations, further promote flexibility and the scope of application of product.

Above-described is only the preferred implementation of coupler of the present invention; it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention; can also make some distortion and improvement, these all belong to protection scope of the present invention.
