For solving the problems of the technologies described above, the utility model adopts so a kind of radio frequency connector assembly, comprises public connector and female connectors; Described public connector comprises the first outer conductor, the first insulator, the first inner wire, the first insulating trip and the first aluminium hydraulic pressed connecting pipe, and the front end of described the first inner wire is provided with contact pin; Described female connectors comprises the second outer conductor, the second insulator, the second inner wire, the second insulating trip and the second aluminium hydraulic pressed connecting pipe, and the front end of described the second inner wire is provided with jack; In the time that plug-in mounting connects, the contact pin of described the first inner wire inserts in the jack of described the second inner wire, described public connector also comprises a cylindrical shape contact head being made of metal, this contact head is sleeved on the front end of described the first outer conductor, in the time that plug-in mounting connects, described contact head is electrically connected with described the second outer conductor.
As a kind of improvement of the present utility model, be provided with an annular groove at the front end of described the first outer conductor, on the endoporus wall of described contact head, be provided with one to projecting inward annular protrusion, thereby described contact head embeds the front end that is sleeved on rotationally described the first outer conductor in described annular groove by its annular protrusion.
As further improvement of the utility model, the groove width of described annular groove is greater than the width of described annular protrusion, also offers some uniform open slots on the stack shell of described contact head.
Adopt after said structure, the utlity model has following beneficial effect:
Because public connector of the present utility model arranges a cylindrical shape contact head being made of metal, and this contact head is sleeved on the front end of the first outer conductor, in the time that plug-in mounting connects, contact head is electrically connected with the second outer conductor, therefore, the connected mode that public connector of the present utility model and female connectors adopt is outer conductor end contact formula, original larger swivel nut that takes up room, thread segment connected mode are abandoned, thereby greatly reduce the volume of connector and the space taking thereof, met well miniaturization, integrated development demand.
The annular groove groove width of the utility model the first outer conductor is greater than the annular protrusion width of contact head, adopt such structure, contact head not only can freely rotate at the front end of the first outer conductor, but also can axially moving forward and backward along the first outer conductor, thereby make the first outer conductor more reliable with being electrically connected of the second outer conductor, conductivity performance is better.
