Description

Technical Field

[0001] The utility model belongs to the technical field of board-to-board connectors, and in particular relates to a novel board-to-board connector. Background Art

[0002] Board-to-board connectors are used to connect the circuits of two PCBs into an integrated pathway, enabling low current or signal transmission between the two PCBs. At present, existing board-to-board connectors still have some shortcomings. The current board-to-board connectors are divided into two structural forms: male and female. The main problems are: (1) If the plug-in and pull-out force is large, the male and female connectors are easily damaged. Therefore, a smaller plug-in and pull-out force is required. If the plug-in and pull-out are repeated many times, they are easily worn or deformed, resulting in a small retention force between the two connectors. The board-to-board connectors are easily loosened, resulting in poor fastening between the two, a loose structure, and a loose terminal structure, which affects the performance of the connector; (2) Because one end of the connector is male and the other end is female, it is necessary to install male and female connectors on the same PCB board. The female connector on one PCB board needs to be plugged into the male connector on another PCB board, or the male connector on one PCB board needs to be plugged into the female connector on another PCB board. If all PCB boards are male or all female, the two PCB boards cannot be plugged into each other, which reduces the versatility; (3) The connector adopts two structural forms, one male and one female, which requires two sets of customized molds to be processed and manufactured respectively, which also increases the processing and manufacturing cost of the connector.
