Background technology

Radio frequency (RF) coaxial connector is typically considered a kind of element being installed on cable or on instrument, as biography The element of defeated line electrical connection or separation.It belongs to electromechanical integrated product.Simply say that it mainly serves as a connection.

Existing radio frequency (RF) coaxial connector, such as SMA connectors are using a kind of very extensive standard connector.Usually Connector butt end is provided with nut, is coordinated with nut using the slotted collar with certain elasticity, prevents loosening for nut. But since nut is frequently necessary to lock with other parts, leads to snap ring Joint failure, nut is caused to be easy to loosen； Connector tail end generally cable of the crimping with shielded layer, and cable falls off or is broken frequent occurrence with connector junction, shadow Ring actual use；In addition, there is provision of insulating supporting between internal and external conductor, it there is insulating supporting and led with inner wire, outside The problem of body is tightly combined.Therefore it needs to develop a kind of radio frequency (RF) coaxial connector of function admirable.

Utility model content

Purpose of the utility model is to solve radio frequency (RF) coaxial connector in the prior art is complicated, stability is not Good problem provides a kind of radio frequency (RF) coaxial connector to solve the above problems.

To achieve the goals above, the technical solution of the utility model is as follows：A kind of radio frequency (RF) coaxial connector, including interior lead Body, outer conductor, with the insulating supporting being arranged between inner wire and outer conductor, it is characterised in that：The outer conductor includes the One outer conductor and the second outer conductor, first outer conductor are threadedly coupled with the second outer conductor, second outer conductor PEI supports are provided between inner wire, the center of the supporting surface of PEI supports is arranged there are one central through hole, The support two sides of the PEI supports is each provided with three counterbores, and the inner wire is the processing of beryllium copper elasticity, inner wire perforation The central through hole of PEI supports, and the central through hole is interference fitted with inner wire, the both ends of the inner wire are each provided with Blind hole I and blind hole II, the PEI support are pressed with the second outer conductor, and groove, institute is arranged in the tail portion of second outer conductor It is welded with welded sleeve in the groove stated.

The utility model has the following advantages compared with prior art：Insulating supporting is supported using PEI, and intensity greatly improves, And the design of the counterbore of PEI supports not only improves the impedance matching that radio frequency (RF) coaxial connector has obtained, and saves material, and will not So that dust is fallen into inner wire, has the effect of dust-proof；Inner wire is directly inserted by beryllium copper elasticity processing cable inner conductor, Without welding.
