Floating type radio frequency interpolation compensation mechanism

Abstract

The invention provides a floating type radio frequency interpolation compensation mechanism, aims to solve a reliability problem of connection between printed circuit boards which have low frequency connection and radio frequency connection and are applied to a micro radio station, and improves productibility. According to the floating type radio frequency interpolation compensation mechanism, radio frequency signals are connected through an upper radio frequency socket mounted on an upper unit board, a lower radio frequency socket mounted at a corresponding position of a lower unit board, and a floating radio frequency insertion core connected between the upper radio frequency socket and the lower radio frequency socket, two ends of the floating radio frequency insertion core are two plugs, width of the floating radio frequency insertion core is smaller than groove width of the lower and upper radio frequency sockets, the two end plugs of the floating radio frequency insertion core are different in size, and one is thicker than the other. The mechanism is advantaged in that accurate positioning and mounting strength can be provided through firstly mounting a guiding head and a guiding groove, close connection between a low frequency plug and a low frequency socket can be guaranteed, two ends of the floating radio frequency insertion core have dimension difference, so generation of transverse division force in X and Y axes can be avoided, structural complexity is reduced, enough space between radio frequencies can be further guaranteed, electromagnetic interference can be reduced, and structural miniaturization is realized.

Description

technical field [0001] The invention belongs to the technical field of printed boards, and relates to a small hand-held lifesaving radio station, in particular to a floating radio frequency interpolation compensation mechanism between printed boards with low frequency connection and radio frequency transfer for a small radio station. Background technique [0002] In the design process of printed board products for small radio stations, in addition to low-frequency connections between multiple printed boards, multiple RF transfers are often required. In the past, the following methods were mostly used. [0003] 1.

Problems solved by technology

[0004] This kind of connection will cause two problems: 1) the size of the radio frequency socket is relatively large, which will take up a lot of space, and there are generally more radio frequency sockets that need to be connected between the printed boards, which will make the limited printed boards full of plugs. RF plug sockets lead to relatively concentrated signal transmission and greater RF signal interference; 2) When low-frequency connections and multiple RF transfers are completed at the same time, due to the over-positioning of the plane circumference, there will be insertion errors between the RF plug and the socket , mating is more difficult, and forced mating will generate a large lateral force, affecting product life and reliability

This connection method will also cause two problems: 1) The RF probe head takes up a lot of space, so that the distance between the general boards is at least 16mm, which cannot be applied to small devices; 2) There are many connected RF lines, and the printed board Inter-radio frequency lines are easy to cross, resulting in signal interference, and the space is chaotic

[0008] The radio frequency plugs in this connection method are directly welded on the printed board with radio frequency wires. This connection will cause two problems: 1) The radio frequency wire is easy to break at the welding place, which affects the life and reliability of the product; 2) the printed circuit board There are many radio frequency signals that need to be connected between the boards, and the use of welding radio frequency lines will make it difficult to organize the space between the printed boards
