Description

Technical Field

[0001] The utility model relates to a plug connector, in particular to a board-to-board plug connector. Background Art

[0002] According to the information provided by the manufacturer, board-to-board connectors are used to connect different circuit boards. They have socket connectors and plug connectors that are installed on different circuit boards to connect the circuit boards to each other. In mobile devices such as smartphones, the size of the board-to-board connector components is very small, which reduces the structural strength and life of each connector.

[0003] See also Figure 1 , Figure 2 and Figure 3 The figure shows a three-dimensional schematic diagram of a conventional board-to-board plug connector, a side view schematic diagram of a conventional board-to-board plug connector welded on a circuit board, and a front view schematic diagram of a conventional board-to-board plug connector welded on a circuit board. As can be seen from the figure, the metal parts 10 at both ends of the conventional board-to-board plug connector 1 are located at the lower edge 100 of the metal part 10, and the position corresponding to the short side of the board-to-board plug connector 1 is only located at half the height of the board-to-board plug connector 1. That is to say, when the board-to-board plug connector 1 is welded on the surface of the circuit board 2, the lower edge 100 of the metal part 10 will not contact the circuit board 2, so the structural strength of the metal parts 10 at both ends of the board-to-board plug connector 1 is insufficient when the board-to-board socket connector is plugged into the board-to-board socket connector.

[0004] Furthermore, not only does the metal part 10 reduce the structural strength of the board-to-board plug connector 1, but it also affects the plugging and unplugging of the male end (plug) and the female end (socket), that is, the strength of some structures or the elastic force of the terminals is reduced, resulting in damage caused by structural interference during the process of pulling the male end and the female end apart from each other. In addition, in some usage environments, in order to facilitate charging or information transmission, the electronic module in the device has a large current transmission requirement, which will also increase the requirements for the manufacturing specifications of the board-to-board connector.

[0005] Therefore, how to improve the structural strength of the board-to-board plug connector while making it meet the relevant specifications under high current transmission is indeed a problem that relevant technicians need to think about and solve. Utility Model Content
