And mining three coaxial connector plug is mainly used in the video communication on mine and ground, because environment for use is comparatively abominable, thereby needs explosion-proof, waterproofing design.Be that it is compared with above-mentioned general three coaxial connector, higher good performance need to be arranged.But present mining three coaxial connector waterproof and electrical property also have certain defective, need await further raising, the plug on especially mining three coaxial connector.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, provides a kind of and satisfies under explosion-proof prerequisite, can improve the mining three coaxial connector plug of electrical property.
the utility model solves the problems of the technologies described above the technical scheme that adopts: this is mining three coaxial connector plug, include the center conductor of coaxial setting, main body cover and guard shield, be provided with inner insulator between described center conductor and main body cover, be provided with external insulator between described main body cover and guard shield, and be outside equipped with the swivel nut that connects use at described guard shield, it is characterized in that: have the flange collar that offsets with the inner insulator rear end on the inwall of described main body cover, has flange on the oral area lateral wall of the insertion end of this main body cover, have a plurality of axial slit and form flexure strip between adjacent axial slit along circumferential interval on the sidewall of the oral area of the insertion end of this main body cover, and in this main body cover, also have respectively and inner insulator on lateral wall, external insulator match in, outer pawl.
Preferably, can have step on the rear end face of described inner insulator, described flange collar and this step surface offset, and can play compensating action, to improve the radio-frequency performance of connector.
In above-mentioned each scheme, have the two pawls that match with external insulator on the madial wall of described guard shield, the rollback after can further preventing from connecting.
Further improvedly be, the oral area of the tail end of described guard shield has inwardly inclined to one side kink, and External Insulation plays the effect of fool proof.
Described guard shield has seal groove on the lateral wall of contiguous tail end.During use, when band glue heat-shrinkable T bush blows to herein, can play the anti-back sealing function, to improve water resistance.
Have the elongate slot of axial distribution along circumferential interval on the oral area sidewall of the insertion end of described guard shield and make and form elastic wall between adjacent elongate slot, make the contact performance after connection better.
Compared with prior art, owing to having increased inside and outside pawl on main body cover of the present utility model, therefore when with after connector body is connected, can prevent rollback of the present utility model, utilize simultaneously flange collar, can have foolproof function preferably, by means of axial slit and flange, contact reliability of the present utility model can be increased, and then the purpose that improves electrical property can be reached.
