That is, a device that connects two active devices to transmit current or signals. The male end and the female end can transmit information or current after contact, and it is also called a connector. Connectors are widely used in electronic devices to achieve the electrical connection of internal electrical components. With the continuous development of electronic technology, their application scope is becoming more and more extensive. Whether it is equipment used in industrial production or mobile phones, computers, MP3s, etc. that people often use, connectors play an indispensable and important role.

Its main function is to provide a reliable electrical connection, allowing signals, power, or data to be transmitted between one circuit board and another. Most of the power terminals of existing BTB connectors are arranged outside the insulating body, which is easy to contact with external metals and cause short circuits, and is also easy to be deformed and damaged by external collisions, shortening the service life. At the same time, its power terminals lack elasticity. When plugging, the force received by the power terminals directly acts on the pads of the circuit board from the welding part. After repeated plugging, the welding between the welding part and the pads will become unstable, causing the connector to fall off the circuit board. Therefore, it is necessary to improve the existing BTB connectors. Content of the Utility Model
