Creation Description (l) [Technical Field of New Type] This creation provides an improved structure of a board-to-board connector, especially a board-to-board docking connector using a buckling mechanism with a card portion and a card slot. [Previous technology] The development trend of electronic products has always been to reduce the size of electronic components, because many electronic components are connected to preset circuits on various PCB boards. These pcb boards must be connected together in a way that effectively and reliably interconnects the circuits on one pcb board with the circuits on another pcb board. In order to achieve the connection of two PCB boards on a parallel plane to reduce the size of electronic components, the industry has developed a surface-mount connector, which uses a male (fixed terminal) connector and a female connector ( Electrical connection between two PCB boards formed by the combination of elastic terminals) connectors. There are still many technical problems in the manufacture and use of this reduced size board-to-board connector, such as: (丨) the process of riveting the rubber core and the terminal is complicated, which is not conducive to reducing the cost of the product; (2) the riveting device Limited fixing strength, which can easily lead to poor electrical deformation of the product; (3) The small spacing of the terminal holes makes it difficult to reduce the size of the product, and it is easy to puncture the partition wall during assembly, resulting in electrical abnormalities; (4) The elastic mutual interference buckles of the male and female connector terminals are not stable and are not suitable for the development of thin and light products; (5) It is not conducive to reducing costs.
