According to the SMP radio frequency coaxial load disclosed by the invention, the technical problems of inconvenience in disassembly and assembly and invariable impedance of the existing SMP radio frequency coaxial loads are solved, and the SMP radio frequency coaxial load has the advantages of being adjustable in impedance, convenient in installation or detachment and easy in implementation.
Description
Technical field
The present invention relates to the load of a kind of SMP RF coaxial.
Background technology
Along with machine system miniaturization, modularization, high-frequency and high efficiency needs are installed; The SMP RF coaxial adapters with himself advantages of small volume, plug rapidly and characteristics such as frequency of utilization height obtain application more and more widely, brought the extensive use of SMP RF coaxial load thereupon.The coaxial matched load of traditional SMP is installed inconvenient, and impedance is fixing immutable, can not satisfy the demand in market.Under this background, be badly in need of occurring the load of a kind of SMP RF coaxial and satisfy this demand.
Summary of the invention
Existing SMP RF coaxial load dismounting is inconvenient in order to solve, the immutable technical problem of impedance, and the present invention provides the load of a kind of SMP RF coaxial.
Technical solution of the present invention:
The load of a kind of SMP RF coaxial comprises first outer conductor, first insulator, first inner wire, second outer conductor, second insulator, second inner wire and resistance, and said first inner wire, second inner wire are connected with resistance successively; Said second outer conductor is threaded with first outer conductor; Its special character is: the said first outer conductor lateral surface begins to be disposed with draw-in groove, cylindrical installed surface and multi-edge column-shaped anti-rotation flange from end face, is provided with the open flume type snap ring in the said draw-in groove; The inner face of said first outer conductor is provided with the taper platform that stretches to second outer conductor, and said second outer conductor is provided with the bellmouth that is complementary with taper platform position and tapering.
Above-mentioned open flume type snap ring is the taper snap ring, and the small end face of said taper snap ring is near the first outer conductor end face.
Above-mentioned multi-edge column-shaped anti-rotation flange is the quadrangular anti-rotation flange.
Institute of the present invention has advantage:
1, SMP RF coaxial provided by the present invention load; Through inner face the taper platform is set at first outer conductor; The bellmouth of taper platform coupling is set in the corresponding position of second outer conductor; Through regulating length of thread engagement between second outer conductor and first outer conductor, the gap gradual change between corresponding taper platform and bellmouth, thus realized the impedance adjustable of second outer conductor and first outer conductor.Therefore, the load of SMP RF coaxial is according to the difference of screwing length, and the characteristics of product impedance has obtained variation, has reduced standing wave.
2, SMP RF coaxial provided by the present invention load is provided with tapering open flume type snap ring on outer conductor, need be through not tightening or unclamping and realize installing or dismantling from mounting panel, and installation or removal are convenient, realize easily.
3, when load is pressed into mounting panel; Snap ring shrinks along tapering and gets in the installing hole; Putting in place, expansion is stuck to mounting panel automatically in the back; First installing hole on installed surface and the mounting panel cooperates, and is installing realization anti-shake and anti-channeling like this, again because the anti-rotation flange on the shell has structurally been realized anti-rotation with the cooperating of second installing hole on the mounting panel.Product is fixed on the installation panel firmly.When the stressed once more contraction of snap ring, product just can disassemble from mounting panel easily.
Description of drawings

Fig. 2 is the cutaway view of Fig. 1;
Fig. 3 is the structural representation of mounting panel of the present invention.
Wherein Reference numeral is: 1-first outer conductor, 2-first insulator, 3-first inner wire, 4-second outer conductor; 5-second inner wire, 6-second insulator, 7-resistance, 8-mounting panel; 9-first installing hole, 10-second installing hole, 11-snap ring, 12-installed surface; The 13-anti-rotation flange, 14-taper platform, 15-bellmouth.
Embodiment
Like Fig. 1, shown in 2, SMP RF coaxial of the present invention load comprises first outer conductor, first insulator, first inner wire, second outer conductor, second insulator, second inner wire and resistance, and first inner wire, second inner wire are connected with resistance successively; Second outer conductor is threaded with first outer conductor; The inner face of first outer conductor is provided with the taper platform that stretches to second outer conductor, and second outer conductor is provided with the bellmouth that is complementary with taper platform position and tapering.The first outer conductor lateral surface begins to be disposed with draw-in groove, cylindrical installed surface and four prism type anti-rotation flange from end face, is provided with open flume type taper snap ring in the draw-in groove; The small end face of taper snap ring is near the first outer conductor end face.Being connected of second installing hole on anti-rotation flange and the mounting panel realized anti-rotation.Install for convenient, the seamed edge of four prism type anti-rotation flange is provided with rounding.
As shown in Figure 3, mounting panel 8 is provided with first installing hole 9 and second installing hole 10, and the installed surface 12 and first installing hole 9 are suitable, and the anti-rotation flange and second installing hole are suitable.
The principle of the invention: the present invention is through regulating length of thread engagement between second outer conductor and first outer conductor, the gap gradual change between taper platform and bellmouth accordingly, thus realized the impedance adjustable of second outer conductor and first outer conductor.The present invention realizes easy disassembly through the snap ring in the load.This snap ring is the tapering open flume type, has certain elasticity like this.When product when the one side of mounting panel is pressed into mounting panel; Snap ring shrinks along tapering and gets in first installing hole; The back snap ring that puts in place expands stuck to the another side of mounting panel automatically; Installing realization anti-shake and anti-channeling like this, again because the anti-rotation flange on the shell has structurally been realized anti-rotation with the cooperating of second installing hole on the mounting panel.Product is fixed on the installation panel firmly.When the stressed once more contraction of snap ring, first outer conductor just can be movable in first installing hole, and product just can disassemble from mounting panel easily.
