Elastic contact ring for signal transmission

Abstract

The invention discloses an elastic contact ring for signal transmission. According to the invention, metal alloy wires are used as a base material, and a latticed sheet is formed by orderly weaving the metal alloy wires, and then the latticed sheet is coiled into a hollow cylinder shape. The triangular, quadrilateral, hexagonal or wavy latticed sheets are formed by ordered weaving, so it is convenient for strictly controlling the geometric body structure and the total material amount forming the elastic contact ring, so that the elastic contact ring with the same specification is good in mechanical property and electrical property consistency and stable and reliable in work. Compared with a contact piece formed in the prior art, the contact ring further has the advantages that the contactarea of the upper end face and the lower end face is large, the elastic force is evenly distributed, the surface contact is formed between the elastic contact ring and the PCB, and the problem of tolerance in the radial direction and the axial direction when the PCB is connected with the PCB is solved. The contact ring also has the advantages of high density, high flow conductivity and high fatigue resistance.

Description

technical field [0001] The invention relates to the technical field of elastic connectors, which are used for signal transmission and connection between PCB boards, in particular to an elastic contact 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. The problem is that the above-mentioned structures are in axial rigid contact, which cannot meet the requirement for radial tolerance when connecting PCB boards to PCB boards, reduces the connection efficiency of PCB boards, and restricts the application effect of PCB boards. [0003] With the advent of the 4G and 5G era, the sep...

AI Technical Summary

Problems solved by technology

The problem is that the above-mentioned structures are in axial rigid contact, which cannot meet the requirements for radial tolerance when connecting PCB boards to PCB boards, which reduces the connection efficiency of PCB boards and restricts the application effect of PCB boards.

The above structure only solves the tolerance problem of the axial elastic connection between the PCB board and the PCB board, but 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

In addition, due to the disordered arrangement of the elastic contact piece formed by the random winding of the metal wire, the mechanical and electrical properties of the elastic contact piece are difficult to control, and the product performance is poor in consistency, stability and reliability.
