High-performance housing for radio frequency coaxial connector

Abstract

The invention relates to a high-performance housing for a radio frequency coaxial connector. The interior of the housing includes a plugging pin channel, an insulator channel and a connecting channelwhich are distributed sequentially from the front part to the rear part of the interior of the housing; the plugging pin channel is a cylindrical channel; the edge of the plugging pin channel is provided with a first inclined surface which extends outwardly; the inclination angle A of the first inclined surface is 30 degrees; the insulator channel includes a first channel, a second channel, and athird channel; the inner diameters of the first channel, the second channel and the third channel are sequentially decreased; the first channel, the second channel, and the third channel are cylindrical channels; a second inclined surface is disposed between the first channel and the second channel; the inclination angle of the second inclined surface is 45 degrees; a third inclined surface is disposed between the second channel and the third channel; the inclination angle of the third inclined surface is 60 degrees; the outer surface of the housing is provided with a first recessed ring and asecond recessed ring; the cross section of the first recessed ring is of a trapezoidal structure; and the cross section of the second recessed ring is of a square structure. The high-performance housing has the advantages of good clamping effect, high mechanical reliability, effectively improved electrical property and signal transmission effect.

Description

technical field [0001] The invention relates to the field of radio frequency coaxial connectors, in particular to a high-performance housing of the radio frequency coaxial connector. Background technique [0002] RF coaxial connectors are generally considered to be a component that is attached to a cable or installed on an instrument, as a component that is electrically connected or separated by a transmission line. It is a mechatronic product. Compared with other electronic components, the development history of RF coaxial connectors is relatively short. The UHF connector that appeared in 1930 was the earliest radio frequency coaxial connector. During World War II, due to the urgent needs of the war, with the development of lightning, radio and microwave communications, medium-sized series such as N, C, BNC, and TNC were produced. After 1958, miniaturized products such as SMA, SMB, and SMC appeared. In 1964, the US military standard MIL-C-39012 "General Specifications for...

Problems solved by technology

[0004] The existing RF coaxial connectors are divided into straight type and angled type. Often, the cost of the angled type connector is relatively high, the positioning effect of the shell on the insulator is poor, and the mechanical reliability is relatively low.
