Platform, bush fitting is in shell.
Further, axial step through hole is provided with shell, insulator one end end face connects with shell most inner side ladder end face
Touch.
Further, contact pin is ladder shaft-like, contact pin front end shaft shoulder end face and insulator other end end contact, after contact pin
End face and insulating trip one end end contact.
Further, bushing is provided with shell outermost shoulder hole, bush fitting is in shell.
Further, contact pin is radially provided with the through hole for being used for welding external cable inner wire.
Further, gasket end is provided with the interior chamfering for being used for being welded to connect with external cable screen layer.
Further, insulating trip is set on the inner wire of external cable.
Further, shell is stainless steel casing, and bushing is copper bush,
Compared with prior art, the present invention has following beneficial technique effect：
A kind of SMP types radio frequency (RF) coaxial connector of the present invention, by shell interior axle to be sequentially provided with insulator, insulating trip and
Bushing, sets contact pin between insulator and insulating trip, by bush fitting in shell, by welding the shielding of external cable
Layer is welded with bushing, so as to complete the installation of radio frequency (RF) coaxial connector, the inner wire and external shielding layer of external cable is used
It is weldingly fixed on radio frequency (RF) coaxial connector, it is to avoid using threaded connection, shorten the length of connector, it is simple in construction, install
It is convenient, improve the yield rate and operating efficiency during cable attaching.
Further, it is logical provided with axial step in shell, insulator one end end face and shell most inner side ladder end contact,
Contact pin is ladder shaft-like, contact pin front end shaft shoulder end face and insulator other end end contact, contact pin rear end face and insulating trip one end
End contact, pass through the ladder shaft shoulder carry out axial limiting, it is ensured that insulator contact pin axial direction stability.
Further, shell is stainless steel casing, it is ensured that its is environment resistant, and bushing is copper bush, be easy to external cable with
The direct welding of copper sheathing, it is ensured that the stability of connector, and the length of connector is shortened by welding.
