[0002] A BTB test socket is a device or tool specifically designed for testing board-to-board (BTB) connectors. BTB connectors, also known as board-to-board connectors, evolved from flexible printed circuits (FPCs) to better accommodate the miniaturization and modularization of electronic devices. These connectors are simple to install, typically achieving electrical continuity through the mating of springs between male and female connectors. They are widely used in high-precision mobile devices such as mobile phones, medical devices, automobiles, and aerospace applications.
[0003] Currently, the structure of BTB test sockets on the market basically uses micro-pins or Pogo Pins as BTB connectors. With these two types of connectors, during the test process, the test circuit board needs to be in close contact with the contact points of the BTB connector to establish a stable electrical connection. If the contact pressure is too high, it will leave marks on the surface of the test circuit board. Therefore, a BTB test socket is proposed. Utility Model Content
