Technical Field
[0001] The utility model relates to the technical field of electric connectors, in particular to a circular high-frequency integrated anti-misplugging electric connector. Background Art
[0002] In the current field of electronic connection technology, integrated connectors are highly favored due to their excellent environmental adaptability and high reliability. They are widely used in key fields such as postal and telecommunications, satellite antenna communications, and ships. These connectors typically use a fixed connection between boards to ensure stable performance in various complex environments.
[0003] However, traditional fixed-connection connectors between boards have significant drawbacks during use. In particular, the internal connectors of the plug and receptacle can easily mate incorrectly due to improper operation or design flaws. Forcing the connection can easily damage the internal connectors and even cause short circuits in electronic components, posing a serious threat to the stable operation of the entire system.
[0004] Furthermore, the structural design of traditional connectors often presents the risk of misinsertion. This not only leads to docking failure and reduced efficiency, but also compromises the connector's electrical reliability. Furthermore, frequent misinsertion and forced insertion can negatively impact the product's lifespan, reduce performance, and even damage internal connector components, leading to connection failure and ultimately affecting the overall system's functionality.
