Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

A kind of non-contact radio-frequency capacitance coupling type coaxial connector as shown in figures 1-4, including by A outer conductor 11, A Insulator 13 and the plug 1 being set with of A inner conductor 12 and the socket 2 being set with by B outer conductor 21, B insulator and B inner conductor 22, It is characterized by: the plug 1 and 2 end of socket are respectively connected with diamond shape flange 3, the A inner conductor 12 with inside B inner conductor 22 It is equipped with high pressure distributed capacitor；1 end of plug is also equipped with spring 15, guiding shell 16, radially-directed shell 17, institute Spring 15 is stated to be wrapped on 17 outer wall of radially-directed shell.

Capacitor is constructed in radio frequency connector inner conductor, which is distributed capacitor, with integrated connection device and mating The matching of coaxial cable distribution capacitor, characteristic impedance are 50 Ω.Structure is as shown in Fig. 5~6.Since coaxial connector is led by interior Body and outer conductor form, therefore there are two kinds of structures for the product: one is the as shown in Figure 5 design capacitance between inner conductor, Another kind as shown in Figure 6 is in inner conductor, the equal design capacitance of outer conductor.The two difference is to be grounded altogether in RF transmission system With the equal design capacitance of inner conductor, outer conductor can be isolated over the ground, the former does not have this function.

Plug 1 and socket 2 have used wedge angle at 60 degree of diamond shape flange 3, are installed by flange hole screw thread, so that installation Reliably, flange area is utmostly secondly reduced under the premise of identical mounting hole spacing relative to round, rectangular flange, mitigated Product weight.

Plug 1 and 2 structure of socket are compact, under the premise of equal transport power (200W) by product height down to minimum, Wherein 1 height of plug is 27mm, and 2 height of socket is 20mm.

The full surface of 1 outer conductor of plug and inner conductor have used new insulation material PEEK14 coating package, PEEK14 material The high-temperature stability of material, so that the product can be used in 200 degrees Celsius of hot environment.

Spring 15 has been used on plug 1, when so that it being plugged together with socket 2, axially can float, maximum float amount be+ 1.5mm when plate can be prevented multiple to plate while being plugged together, is crossed and is plugged together or owe to plug together phenomenon.

Guiding shell 16, radially-directed shell 17 are used on plug 1,120 degree of the inner hole circle design of guiding shell 16 is tiltedly Face, 105 degree of inclined-planes of exit orifice circle design of radially-directed shell 17, cooperation spring 15 uses, so that the product is deposited in radial direction It is floating, maximum float amount is+1mm, and when plate can be prevented multiple to plate while being plugged together, plug 1 and socket 2 exist not to just Bias can not plug together.

When plug 1 and socket 2 plug together, between A outer conductor 11 and B outer conductor 21, between A inner conductor 12 and B inner conductor 22 Design has insulating materials PEEK14 coating package, therefore, A outer conductor 11 and B outer conductor 21, A inner conductor 12 and B inner conductor 22 it Between there is no contacts, and when convention connectors plug together, there is firm contact in inner conductor, outer conductor, therefore, which is one The novel contactless connector of kind, there is essential distinction compared with convention connectors.Based on this feature, which plugs together the longevity Life is convention connectors 2 times or more, and can be used as a kind of radio frequency rotary joint use during plugging together with 360 degree rotation.

Inner conductor, outer conductor do not contact when plug 1 is plugged together with socket 2, are in an off state, and devise distribution therebetween Capacitor, this characteristic couple RF signal, ensure that RF signal continuously transmits, effectively filtering, blocking DC circuit, avoid instrument Device, equipment are broken by direct current.

It plugs together active interface and has used material PEEK, the superpower wear-resistant characteristic of material determines the type connector service life more It is long.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
