For this reason, the utility model is by the following technical solutions: a kind of connector box cable fast sealing assembly, it is characterized in that, described connector box cable fast sealing assembly comprises O-ring seal, cable fixture, stop collar and screw part, O-ring seal is soft right cylinder, and be provided with axial cable mounting hole, be used for installing cable, on O-ring seal right-hand member end face, be provided with an axial boss, described cable fixture is polygon cylinder, cylinder left end is provided with axial step through hole, described axial boss is flush-mounted in described axial step through hole, described stop collar inner chamber left end is provided with the step end face towards right-hand member, on internal chamber wall, be provided with the limiting section corresponding with described polygon cylinder, stop collar inner chamber right-hand member is provided with internal thread, the described part that screws is provided with the radial groove that connects two ends, radial groove facilitates cable to clamp, screw on the outer peripheral face of part one end and be provided with the external thread matching with described internal thread, in the time that stop collar is set in described O-ring seal, screwing part is installed on cable, and make the external thread one end that screws part be flush-mounted in stop collar and be threaded with described stop collar.
As to technique scheme supplement and perfect, the utility model also comprises following technical characterictic.
Described cable fixture is radially provided with open slot, when installation, directly cable is embedded in described open slot, makes easy to loading and unloading.
Described cable fixture right-hand member is provided with clamping head, on the internal chamber wall of clamping head, is set to dentation, and when cable is threaded onto cable fixture, dentation is pressed against cable outside surface, plays the clamping action to cable.
Described O-ring seal left end is provided with pad, and pad footpath is upwards provided with opening, convenient installation when clamping cable.
When the utility model uses, cable is threaded onto in O-ring seal, O-ring seal left end clamps pad, right-hand member clamps cable fixture, then stop collar is set in simultaneously to described pad, on O-ring seal and cable fixture, pad left end end face is resisted against on the step end face in stop collar, screw part and be installed in stop collar right-hand member, screw connection by the screw thread that screws part and stop collar, make the left end end that screws part to cable fixture applied thrust, and then make cable fixture apply power to O-ring seal, make O-ring seal reach axial compression, be radially expanded, reach sealing function.
Use the utility model can reach following beneficial effect: by screwing screwing of part and stop collar, to make O-ring seal carry out axial compression, be radially expanded, make good sealing effect, and can not make O-ring seal follow rotation screwing in process, improve sealing effectiveness, and easy for installation.
