Specific embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the airproof metal cable waterproof connector structural schematic diagram of the utility model embodiment.
Referring to Figure 1, it is the airproof metal cable waterproof connector of the utility model embodiment, including adapter body 2, connects
Head core 4, seal cartridge 5 and nut 6,2 top internal diameter of adapter body are greater than bottom inner diameter, including the adapter body 2
Inner hole step is formed in the middle part of hole；The 2 top inward flange of adapter body is equipped with wedge-shaped rotation stop groove, and 4 top of connector core is outer
Edge, which is equipped with, to be fastened on inside adapter body 2 with the matched ending tendon transfer of rotation stop groove, the connector core 4 by ending tendon transfer, rotation stop
The cooperation of muscle rotation stop groove prevents connector core and cable from following cap rotation when nut screws in locking cable；The connector core
4 top surfaces are equipped with card slot, and 5 bottom of seal cartridge is equipped with the plug-in card with pocket matches, and the seal cartridge 5 is set by plug-in card card
In connector core 4；The connector core 4 is arranged above interior hole step, is provided between the connector core 4 and inner hole step
Flat seal ring 3.
Specifically, being the airproof metal cable waterproof connector of the utility model embodiment, connector core 4 and seal cartridge
5 internal diameters are identical, and 4 internal diameter of connector core is slightly larger than 3 internal diameter of flat seal ring, and 3 internal diameter of flat seal ring, which is slightly larger than, to be connect
Head 2 bottom inner diameter of main body.5 outer surface band of seal cartridge is tapered, and 5 outer diameter of seal cartridge gradually increases from the top to the bottom
Greatly.2 top outside of adapter body is equipped with fixed thread, and 6 inner wall of nut is equipped with and the matched interior spiral shell of fixed thread
Line, the nut inner wall are equipped with limiting stand 7, and the limiting stand 7 is located above internal screw thread.6 inside top surface of nut is oblique
Face, for the nut 6 during rotating fixed with adapter body 2,6 inside top surface of nut inwardly compresses seal cartridge 5.This
The structure of sample, so that the inward hole slope of nut 6 squeezes seal cartridge 5 to lock cable, same time limit when 6 moving in rotation of nut
Position platform 7 forces connector core 4 to contract, is pressed further by seal cartridge 5, further locks cable, connects when limiting stand 7 resists
When head 2 top surface of main body, nut 6 is rotated in place, and is avoided excessively locking and is caused irreversible deformation to seal cartridge 5, influences secondary
