Cutting apparatus for insulating support of air dielectric radio-frequency coaxial connector

Abstract

The invention provides a cutting apparatus for an insulating support of an air dielectric radio-frequency coaxial connector. The cutting apparatus comprises a cutter blade and a cutting base, wherein the cutting base comprises a lower guide sleeve, an elastic piece, a sliding pin and an upper guide sleeve, and the top end of the lower guide sleeve is provided with a first guide groove; the lower end of the upper guide sleeve is provided with a second guide groove, the upper end of the upper guide sleeve is provided with an insulating support containing groove, and the space between the insulating support containing groove and the second guide groove is broken through so as to form a through hole; the sliding pin comprises a sliding block, a guide rod and a locating rod, one end of the guide rod is connected with the sliding block, the other end of the guide rod is provided with the locating rod; the lower guide sleeve and the upper guide sleeve are fixedly connected together; and the elastic piece is arranged in the first guide groove, the upper end of the elastic piece abuts aginst the sliding block, the guide rod of the sliding pin passes through the through hole and extends into the insulating support containing groove by certain distance, and the upper end of the upper guide sleeve is provided with a cutter blade guide groove. The cutting apparatus provided by the invention has the advantages that the structure is simple, the disassembly and assembly are convenient, the fabricating cost is cheap, meanwhile, the operational process is simple, the two-half insulating support after cutting has good uniform symmetry so as to improve qualification rate of products.

Description

technical field [0001] The invention relates to a cutting device for parts of a radio frequency connector, in particular to a cutting device for insulating support of an air medium radio frequency coaxial connector. Background technique [0002] With the continuous development of microwave technology, people have higher and higher requirements for the overall performance of the system, and thus higher and higher requirements for electronic components. Among them, the specific requirements for RF connectors are reflected in the increasing requirements for the frequency of use. high. According to the principle of coaxial cable, to increase the frequency of use of RF coaxial connectors, in addition to reducing the size of the inner hole of the outer conductor and the outer diameter of the inner conductor in equal proportions, there is also the need to reduce the filling between the inner conductor and the outer conductor. The dielectric constant of the insulating medium, consi...

AI Technical Summary

Problems solved by technology

The former is relatively expensive to make injection molds and is not suitable for small batch production mode, while the latter is more applicable and more economical than the former, and is also widely used

However, the latter requires that the two halves of the insulating support after cutting should have good uniformity and symmetry, and there is no defect in the original material, otherwise the coaxiality between the inner conductor and the outer conductor of the assembled connector will be poor or the impedance will not match. Eventually result in scrap or poor electrical performance

However, it is extremely difficult to ensure that the two halves of the insulating support after cutting meet the requirements, and the scrap rate is often high.
