Description

Floating board-to-board connectors Technical Field

[0001] The present invention relates to the technical field of board-to-board connectors, in particular to a floating board-to-board connector. Background Art

[0002] Floating board-to-board connectors are used to connect two circuit boards. They generally include a male and female connector (also called a male connector and a female connector) that plug into each other. The female connector is equipped with a floating mechanism. When plugged into the male connector, it can eliminate the misalignment of the circuit boards during assembly and reduce the force between the connector and the circuit board. Therefore, it is widely used for electrical connections in vibrating environments.

[0003] With the widespread application of board-to-board (BTB) connectors in various fields, the demand for connectors is not limited to signal transmission. Some users also need high current transmission. At the same time, the use of a floating structure can absorb the mating deviation between the male and female sockets and offset some soldering tolerances when multiple board-to-board connectors are used on the same substrate. The floating structure also allows the connector to operate normally in a vibration environment. In addition, with the miniaturization of electronic devices in recent years, the connectors mounted on the circuit board are required to be miniaturized.

[0004] However, the existing floating board-to-board connector structure is too simple, and it is impossible to simultaneously set signal terminals and two pairs of power terminals in the board-to-board connector while having floating characteristics.
