SURFACE-MOUNT NUT, CIRCUIT BOARD ASSEMBLY, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2021/103847

A1

A surface-mount nut (20), a circuit board assembly (10), and an electronic device. A blocking portion (30) is provided at an opening (24) of an internal threaded hole (21) at a second end (23) of the surface-mount nut (20), and blocks at least a portion of the opening (24), such that a soldering surface at a bottom end of the surface-mount nut (20) is provided with an added portion corresponding to the blocking portion (30), thus increasing the area of soldering, and improving the connection reliability of the surface-mount nut (20). The blocking portion (30) can prevent soldering from spreading upwards into the internal threaded hole (21) of the surface-mount nut (20) and causing improper installation of a screw. In an assembly scenario in which a tail portion of a screw may interfere with the circuit board due to misuse of a long screw or inadvertent omission of a support frame, the blocking portion (30) abuts the tail portion of the long screw, thus facilitating identification of an incorrect operation such as using a long screw or omitting a support frame by mistake.
