Problems solved by technology

In order to realize the tolerance design, the selected contact form has the following characteristics: a. Use sockets or plugs at both ends, and the connection mode through the middle transfer, which is composed of three components; b. Use sockets or plugs at both ends, through welding The existing problem is that the above-mentioned structures are all in axial rigid contact, which cannot meet the requirements for radial tolerance when the PCB board is connected to the PCB board, which reduces the connection efficiency of the PCB board and restricts the PCB board. The application effect of the board
The above structure only solves the tolerance problem of the axial elastic connection between the PCB board and the PCB board, and does not solve the tolerance problem of the radial connection between the PCB board and the PCB board, that is, the tolerance problem of the shell grounding

Abstract

An elastic shielding ring for signal transmission include an elastic contact ring, tray and conductive rubber pads or cylindrical pins, As that elastic contact re is adopted, the structure of the trayand the conductive rubber pad or the cylindrical pin, the invention is arranged between two PCB boards, The elastic contact coil is in contact with the electrical contact area of the first PCB board,the flange of the inner case is bonded with the structure of the second PCB board by the conductive adhesive pad, and the electrical contact area is in contact with the structure of the second PCB board, or the cylindrical pin is inserted in the jack structure of the second PCB board and in contact with the electrical contact area, so that the signal transmission between the two PCB boards is realized. The invention effectively solves the problem of tolerance in axial and radial directions when the PCB board is connected with the PCB board by elastic contact ring and the electric contact areaof the PCB board.

Description

technical field [0001] The invention relates to the technical field of connecting PCB boards, in particular to an elastic shielding ring for signal transmission. Background technique [0002] In the field of civil communication antennas, there are usually multiple signal connection areas on the PCB board. In order to ensure the effective transmission of signals, it is required that the connection between the PCB board and the PCB board can accommodate the tolerance in the axial and radial directions. Existing board-to-board connections are usually made using RF coaxial connectors. In order to realize the tolerance design, the selected contact form has the following characteristics: a. Use sockets or plugs at both ends, and the connection mode through the middle transfer, which is composed of three components; b. Use sockets or plugs at both ends, through welding The existing problem is that the above-mentioned structures are all in axial rigid contact, which cannot meet the...
