Detailed Description
In order to make the purpose, technical solution and advantages of the present technical solution more clear, the present technical solution is further described in detail below with reference to specific embodiments. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present teachings.
The utility model discloses a realize curved formula radio frequency connector 18 GHz's signal transmission function to guarantee that the product has excellent voltage standing wave ratio and the compensation structure of insertion loss performance, it includes casing (3), casing (3) are the structure of buckling, interference connection has preceding insulator (2), back insulator (4) in casing (3), wherein preceding insulator (2) and back insulator (4) contact terminal surface laminating; a bent contact pin (1) is arranged in the front insulator (2), and reflection is reduced by controlling the bending radius of the bent contact pin (1); the front insulator (2) ensures the coaxiality between the bent contact pin (1) and the shell (3); a small contact pin (5) is arranged in the rear insulator (4), and the rear insulator (4) ensures the coaxiality between the small contact pin (5) and the shell (3); the contact positions of the front insulator (2) and the rear insulator (4) and the bent sharp edge of the shell (3) are cut to form an air medium compensation structure (7) so as to realize continuous impedance of the bent positions; and an insulating gasket (6) is arranged at the welding part of the small contact pin (5) and the wire core of the lead and is used for adjusting the impedance value of the welding part.
And a bending compensation structure (8) is formed between the bending part of the bent pin (1) and the front insulator (2) and the rear insulator (4).
The contact positions of the front insulator (2), the rear insulator (4) and the bent sharp edge of the shell (3) are cut at right angles.
When the product is actually used, the three compensation modes of the bending radius compensation of the bent contact pin, the air compensation at the sharp edge of the shell bend angle and the gasket compensation at the welding position of the small contact pin are mainly adopted. The larger the bending radius of the bent contact pin is, the more stable the transition is, the less the signal reflection is, the smaller the voltage standing wave ratio of the product is, and the more excellent the electrical performance is. In the prior art, the bending part of the bent contact pin is 45 degrees, the supporting surface of the insulator is elliptical, and the impedance continuity is damaged to cause signal reflection, so that a right-angle cutting method is adopted to cut off part of the insulator at the sharp edge of the shell bend, leave a proper amount of air, change the medium supporting space proportion, realize the impedance continuity of the bending part, reduce the signal reflection and reduce the voltage standing wave ratio of a product. The small contact pin and the wire core of the wire are welded, and the outer diameter of the wire core is smaller than that of the small contact pin, so that the outer diameter of the inner conductor is changed, impedance mismatching occurs, signal reflection occurs, and therefore gaskets made of insulating materials are added at the welded parts, the impedance value is adjusted, and the impedance matching is enabled to reduce reflection. Aiming at the three compensation structures, voltage standing wave ratio simulation under the frequency of 18GHz is carried out, and simulation results show that the voltage standing wave ratio is not more than 1.1, and the compensation effect is obvious.
The foregoing is only a preferred embodiment of the present invention, and many variations can be made in the specific embodiments and applications of the present invention by those skilled in the art without departing from the spirit of the present invention.
