Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

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

Electric capacity is constructed in radio frequency connector inner wire, the electric capacity is distributed capacitor, device and is connected with integrated connection Coaxial cable distribution electric capacity is matched, and its characteristic impedance is 50 Ω.Structure is as shown in Fig. 5~6.Because coaxial connector is led by interior Body is constituted with outer conductor, therefore the product has two kinds of structures：A kind of is the only design capacitance between inner wire as shown in Figure 5, Another kind as shown in Figure 6 is in inner wire, the equal design capacitance of outer conductor.The two difference is that ground connection is altogether in RF transmission system With the equal design capacitance of inner wire, outer conductor can isolate over the ground, and the former does not possess this function.

Plug 1 has used wedge angle into 60 degree of rhombus flange 3 with socket 2, is installed by flange hole screw thread so that install It is reliable, secondly relative to circular, rectangular flange, under the premise of identical installing hole distance, flange area is at utmost reduced, mitigate Product weight.

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

The full surface of the outer conductor of plug 1 and inner wire have used new insulation material PEEK14 to coat parcel, PEEK14 materials 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 so that when it is plugged together with socket 2, axially can float, maximum float amount for+ 1.5mm, can prevent plate multiple to plate while when plugging together, crossing and plugging together or owe to plug together phenomenon.

Guiding shell 16, radially-directed shell 17 have been used on plug 1,120 degree of the endoporus circle design of shell 16 has been oriented to tiltedly Face, 105 degree of inclined-planes of exit orifice circle design of radially-directed shell 17, coordinates spring 15 to use so that the product is deposited in radial direction Floating, maximum float amount is+1mm, can prevent plate to plate multiple while when plugging together, plug 1 is not aligned with socket 2, is existed It is eccentric, it is impossible to plug together.

When plug 1 is plugged together with socket 2, between A outer conductors 11 and B outer conductors 21, between A inner wires 12 and B inner wires 22 Be designed with insulating materials PEEK14 coating parcels, therefore, A outer conductors 11 and B outer conductors 21, A inner wires 12 and B inner wires 22 it Between in the absence of contact, and convention connectors are when plugging together, and inner wire, outer conductor have firm contact, therefore, the type product is one New contactless connector is planted, there is essential distinction compared with convention connectors.Based on this feature, the connector plugs together the longevity It is more than 2 times of convention connectors to order, and can be rotated with 360 degree during plugging together, and can be used as a kind of radio frequency rotary joint.

Inner wire, outer conductor are not contacted when plug 1 is plugged together with socket 2, are off, and distribution is devised therebetween Electric capacity, this characteristic causes that RF signals are coupled, it is ensured that RF signals are continuously transmitted, effectively filtering, blocking DC circuit, it is to avoid instrument Device, equipment are broken by direct current.

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

Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model Protection domain within.
