Abstract

The present invention discloses an RF coaxial connector for preventing the looseness of a connection nut. The RF coaxial connector is characterized in that an outer conductor is sleeved by a locking mechanism formed by a connection nut, an unlocking nut, a staple sleeve and a spring. One end of the connection nut and one end of the unlocking nut are provided with a serrated mouth. The connection nut is movably connected to the outer conductor by a retaining ring. The unlocking spring is sleeved by the spring, the staple sleeve and the outer conductor. The serrated mouth of the unlocking nut is engaged with the serrated mouth of the connection nut under the effect of the spring, the locking of the connection nut is realized, and the connection nut can not rotate and loose. Compared with the prior art, the RF coaxial connector has the advantages of simple structure and convenient assembly, the locking and separation of the connection nut can be completed only through push and pull operations, the rapid locking of the connection bolt is realized and the looseness of a connection thread is prevented, and the RF coaxial connector is especially suitable for the connection of N series of coaxial connectors.

Description

A kind of radio frequency (RF) coaxial connector preventing connection swivel nut from getting loose
Technical field
The present invention relates to radio frequency connector technical field, especially a kind of and general N series female end prevents from being connected the radio frequency (RF) coaxial connector that swivel nut gets loose after docking.
Background technology
At present, radio signal transmission adopts the N train of radio frequency connector be threaded usually, the radio frequency (RF) coaxial connector be threaded, plug and socket compress mutually, the coincidence in its electrical reference face can be ensured, this structural reliability is higher, but there is the problem connecting swivel nut and easily get loose under vibration, shock environment.Prior art gets loose for preventing connecting swivel nut, and adopt and add security thread hole on connection swivel nut, fix with stainless steel wire colligation, the method, in practical operation, needs enough installing spaces, operates very inconvenient and has a strong impact on installation effectiveness.
Summary of the invention
The object of the invention is a kind of radio frequency (RF) coaxial connector preventing connection swivel nut from getting loose designed for the deficiencies in the prior art, adopt spring bayonet socket retaining mechanism, the locking only needing the action of a push-and-pull just can complete to connect swivel nut be separated, realize the quick locking of connection swivel nut and prevent getting loose of connecting thread, greatly improve the reliability of docking, there is structure simple, easy to assembly, machinery and excellent electrical properties and lower-cost advantage, be especially suitable for the docking of the serial coaxial connector of N.
The object of the present invention is achieved like this: a kind of radio frequency (RF) coaxial connector preventing connection swivel nut from getting loose, comprise the connector plug assembled by insulator, inner wire, outer conductor, pad, lining and installation swivel nut, swivel nut is installed with outer conductor for being threaded insulator, inner wire, pad and lining axial restraint, be characterized in outer conductor is set with by connecting swivel nut, unlock the retaining mechanism that swivel nut, spring and the cutting ferrule that is provided with bail form, cutting ferrule and outer conductor are for rivet; Described connection swivel nut one end is sawtooth mouth, connects swivel nut and is flexibly connected with outer conductor by draw-in groove and back-up ring; Described solution lock tube one end is sawtooth mouth, the other end is provided with " L " shape keyway, unlock swivel nut to be set with by spring and outer conductor, its bail is fastened on the bayonet socket of keyway, unblock swivel nut is fixed on outer conductor, the sawtooth mouth unlocking swivel nut engages with the sawtooth mouth being connected swivel nut under the action of the spring, realizes the locking connecting swivel nut, makes it not rotate and to get loose.
It is simple that the present invention compared with prior art has structure, easy to assembly, the locking only needing the action of a push-and-pull to complete to connect swivel nut be separated, the quick locking realizing connecting swivel nut is connected getting loose of swivel nut with preventing, machinery and electric property improve greatly, reduce costs further, be especially suitable for the docking of N series coaxial connector.
