Utility model content

The purpose of this utility model is to provide a kind of SSMB types male radio frequency (RF) coaxial connector, and the present apparatus ensure that Cable core is difficult to twist off or fractureed when component is assembled and the later stage uses, and improves the reliability of CA cable assembly, it is ensured that whole cable The high-frequency electrical performance index of component.

To reach above-mentioned purpose, the utility model is adopted the following technical scheme that：

A kind of SSMB types radio frequency (RF) coaxial connector, including left end are provided with the second housing of shrinkage pool and are arranged in shrinkage pool Second insulator, second housing and the second insulator are provided with coaxial through-hole, and second housing left end has been connected through a screw thread outside first It is provided with shell, the first shell in the first insulator, the first insulator and is provided with inner wire, second housing right-hand member is inserted with external electricity Cable, the inside conductor of external cable is connected through second housing and the second insulation sub-through hole with inner wire one end, external cable shielding Layer is fastened on the outside of second housing outer wall, wire clamp by wire clamp and locked by wire bushing.

Further, the first shell interior shoulder hole from right to left, the first insulator is fastened in the shoulder hole of the first shell.

Further, the inside conductor of external cable is welded with inner wire one end.

Further, the first outer side is provided with fixing nut and internal tooth packing ring.

Further, wire clamp is provided with welding hole.

Further, wire clamp is fixedly connected by welding with external cable screen layer.

Compared with prior art, the utility model has following beneficial technique effect：

A kind of SSMB types radio frequency (RF) coaxial connector of the utility model, in the first shell being connected through a screw thread and second housing The first insulator and the second insulator are inside respectively equipped with, external cable cored wire is passed through to the through hole of the first insulator in second housing It is connected afterwards with the inner wire one end being arranged in the first shell in the first insulation sub-through hole, makes inner wire, external cable cored wire, the One insulator and the second insulator one entirety of formation, inner wire and external cable cored wire are by the first shell and second housing An entirety is formed after tightening, is then fastened on external cable screen layer on the outside of second housing outer wall, wire clamp again by wire clamp Locked by wire bushing, form secondary fastening, external cable screen layer is more firmly fixed on second housing, using When, external cable cored wire is not acted on by independent external force, is not easily broken, it is ensured that the transmitting of signal, and ensures to assemble in component And the later stage when using cable core be difficult to twist off or fracture, improve the reliability of CA cable assembly, it is ensured that the height of whole CA cable assembly Frequency electrical performance indexes.

Further, wire clamp is fixedly connected by welding with external cable screen layer, makes external cable screen layer weld part The cored wire of position does not receive external force effect individually, directly will not be made as an entirety in the use of component by external force yet With.
