Abstract
The invention relates to a quick plug radio frequency coaxial connector. When the connector available on the market currently is plugged, a corresponding body clearance is generated between a convex front end face of an outer conductor of a female plug and the concave front end face of an outer conductor of a male plug, so electric performance of the connector declines; meanwhile, the contact is susceptible to causing connection failure, and disassembly and assembly are difficult. The invention discloses a quick plug connector, which comprises a male plug and a female plug which are in insertion connection, wherein the male plug comprises a first outer conductor, a first inner conductor, a contact and a front sleeve; a convex barb surrounds the front end of the contact; a spacer sleeve is arranged between the first outer conductor and the contact, and a spring plate is arranged at the inner front end of the first outer conductor; and a spring positioned at the rear end of the contact is arranged between the front sleeve and the first outer conductor. The connection structure provided by the invention guarantees effective separation, ensures that the connector has high electric performance and that the female plug can be inserted and connected with a threaded female plug, and therefore has two purposes.
