Detailed Description
The following detailed description is made with reference to the accompanying drawings.
Referring to fig. 4, a high-reliability detachable multi-rf channel connector includes an rf channel 1, a housing 2, a spring 3, and a locking screw 4. The number of the radio frequency channels 1 is not limited to the number shown in the figure, the number of the channels can be changed according to the user requirement, the embodiment is four radio frequency channels, and when the number of the radio frequency channels is more, the structural advantage of the invention is more obvious.
The radio frequency channel 1 consists of three parts, namely a contact pin 1-1, an insulator 1-2 and a casing 1-3 of the radio frequency channel from inside to outside in sequence, the fixing modes of the three parts have various common structures, and the common structures are not explained in detail in the invention. The shape structure of the radio frequency channel, namely the shell 1-3 of the radio frequency channel, is a lower part of an upper circle, and the excircle of the upper part of the shell 1-3 of the radio frequency channel is arranged in the round hole of the upper part of the shell 2 and forms clearance fit with the round hole of the shell 2; the lower four sides of the shell 1-3 of the radio frequency channel are arranged in the lower rectangular hole of the shell 2 and form clearance fit with the long edge of the lower rectangular hole of the shell 2.
