High-stability contact head of radio frequency coaxial connector

Abstract

The invention provides a high-stability contact head of a radio frequency coaxial connector. The contact head is of an integrated structure, and the contact head comprises inserting strips, a plug-inbase and a shell connecting base, wherein a first contact channel and a second contact channel are formed in the contact head, the first contact channel is located at one end in the shell connecting base, the second contact channel is connected with the first contact channel, and the inner diameter of the first contact channel is larger than that of the second contact channel; the joint of the shell connecting base and the plug-in base is provided with an inclined surface; one end of the plug-in base is connected with the shell connecting base, and a plurality of protruding bases are arrangedat the other end of the plug-in base in the circumferential direction; the protruding bases are arranged on the periphery of the end face of one end of the plug-in base in the circumferential direction, and each the protruding base is of an arc-shaped structure; the number of the inserting strips is consistent with that of the protruding bases, and each inserting strip is a long strip of an arc-shaped structure; one end of each inserting strip is connected with the corresponding protruding base, and a protrusion with two low ends and a high middle is arranged on the outer surface of the otherend of each inserting strip; the protrusions and the insertion strips are of an integrated structure, and the section of each protrusion is of an isosceles triangle structure. The contact head is stable and firm in connection and convenient to install.

Description

technical field [0001] The invention relates to the field of radio frequency coaxial connectors, in particular to a high-stability contact head 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 ...
