Technical Field

[0001] The present invention belongs to the technical field of electrical contact connection, and in particular relates to a wool button integrated component realizing heat management and signal transmission functions. Background Art

[0002] As multifunctional boards develop towards structural and functional integration, wool buttons are increasingly widely used in weapon systems due to their solder-free, low-profile, and high-density characteristics. In order to meet the needs of structural and functional integration and integration of a small intelligent board, it is urgent to develop an interconnection component that realizes thermal management and signal transmission functions. CN202223529563.9 provides a multi-channel high- and low-frequency integrated floating connector, including a mounting plate, a radio frequency contact, a first low-frequency contact, and a second low-frequency contact. The original inner conductor of the connector is replaced with a wool button, so that the radio frequency and low-frequency channels of the connector can achieve bidirectional floating while also having the characteristics of ultra-small size and surface welding.
