[0002] BTB connectors are connectors used for connecting circuit boards inside electronic devices. BTB connectors are typically used for high-density, high-reliability circuit board connections, especially in mobile devices, laptops, tablets, servers, and other portable electronic devices.

[0003] To achieve the desired functions or adapt to different circuit boards, researchers have developed BTB connectors in various sizes. However, when the size of the BTB connector is small, the existing connectors fill the pin holes with pins, resulting in a small gap between the pins. Safety testing requires electrical clearance between pins, so in high-voltage environments, smaller BTB connectors cannot withstand high voltage, cannot function properly, and fail safety tests. Therefore, it is necessary to improve existing BTB connectors. Utility Model Content
