Description

Technical Field

[0001] The utility model belongs to the technical field of wool button connectors in the field of signal transmission, and specifically relates to a 164-core wool button connector, which is used for realizing vertical interconnection between two parallel printed boards. Background Art

[0002] In electronic devices, parallel printed circuit boards are mainly connected through vertical interconnect connectors. Traditional vertical interconnect connectors mainly include surface mount soldering and through-board soldering in terms of plug-in methods. However, these methods have problems such as large plug-in and pull-out force when blindly plugging between boards, large connector size, poor high-frequency performance, and complex maintenance. They cannot meet the development needs of electronic systems towards miniaturization, integration, high speed, and lightweight.

[0003] The button is an elastic body with certain dimensions that is formed by a metal wire through a certain process. The button connector realizes vertical interconnection between parallel printed circuit boards by contacting the axial section of the button elastic body with the corresponding printed circuit board pad.

Patent CN202111308411.3 discloses a vertical interconnection structure between boards, including a metal frame, buttons, dielectric columns and outer conductors. For the transmission structure of drilling a circle of grounding button mounting holes on the isolation frame, the structural size can be reduced, and on the basis of achieving coaxial transmission, the microwave transmission performance is better. Patent CN201921640206.5 discloses an inter-board button connection module, in which a button jack is assembled on an insulating base. The two ends of the jack have a large aperture, which is convenient for the button to be installed in the insulating base, and the middle aperture is small, which is convenient for restraining the button and ensuring the stable installation of the button. A special structure of glue injection holes is opened on the side of the insulating base, and the button is fixed by glue injection to achieve gap assembly, and the button can be effectively fixed to prevent it from falling off.
