Description

Technical Field

[0002] Board-to-board connectors are connector products with the strongest transmission capacity among all connector product types. They are mainly used in power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, military manufacturing and other industries. Board-to-board connectors include floating female connectors and male connectors. The male connector is plugged into the floating female connector, so that the floating female connector and the male connector can be connected in a floating manner to meet the requirements of reliable floating connection of the board-to-board connector.
