Description

Knob type connector Technical Field The application relates to the field of connectors, in particular to a knob type connector. Background Connectors are widely used in various electrical and signal connection applications as an indispensable component in electronic devices. In the design of knob-type connectors, the fixed connection between two connectors (typically male and female) is critical for achieving electrical and signal transmission. Most of the existing connectors adopt screw fastening or plug spring piece type design, and the screw fastening type connector tightly connects two parts together through screws, so that higher connection strength and stability are provided. However, in the application scenario of frequent disassembly and assembly, repeated tightening and loosening of the screw may cause thread wear and thus loosening. In addition, the screw fastening process requires special tools, so that the complexity of installation and maintenance is increased, the operation time is long during connection, and quick connection and disconnection cannot be realized. The plug spring plate design realizes the plug connection of the male head and the female head by relying on the elastic deformation and the restoring capability of the spring plate, and has the advantages of simple and convenient installation and easy replacement. However, in actual operation, the user needs to spend a long time pressing the spring plate, which reduces the working efficiency. Accordingly, there is a need to provide a knob type connector that can be quickly locked and unlocked.
