Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to a connector with a screw locking structure. Background Art

[0002] With the development of miniaturization and multi-function of electronic devices, as an indispensable part of electronic devices, connectors are facing higher and higher requirements while ensuring the performance of the devices. Traditional connectors usually adopt a simple plug-and-play design. Although this design is easy to operate, in some application scenarios, especially in high-vibration or environments that require repeated plugging and unplugging, it may lead to unstable connections or even loosening and falling off, thus affecting the overall performance and reliability of the device.

[0003] Deficiencies of the Prior Art

[0004] 1. Without a locking mechanism: There is no locking mechanism at the installation part of the connector and the circuit board, which is not conducive to the positioning during the installation process and the firmness after installation.

[0005] 2. Problem of positioning accuracy: During the installation process, due to the lack of an effective auxiliary positioning device, it is easy to deviate when fixing the screws, resulting in incorrect installation of the connector, and further affecting the quality of signal transmission.

[0006] Therefore, there are deficiencies in the prior art and further improvement is needed. Content of the Utility Model
