Component 24,25,26 and the seal assembly 27 for being installed on 21 tail portion of plug casing.
The plug casing 21 includes being formed in the plug casing 21 for installing the of the plug insulator 22
One chamber 215 protrudes the first outer bulge loop 211 formed from 21 periphery of plug casing, is recessed positioned at the described first outer 211 front end of bulge loop
In 21 periphery of the plug casing locating slot 213, to be located at 213 front end of locating slot recessed in outside the plug casing 21
The ball grooves 212 enclosed and the external screw thread 214 set on the 21 rear end periphery of plug casing.The seal assembly 27 is installed on institute
It states on external screw thread 214.
The push-and-pull component includes sleeve 25, spring 24 and retainer plate 26.The sleeve 25 is hollow and protrudes above in inner wall
The first internal projecting ring 251 is formed, the both ends of first internal projecting ring 251 are respectively formed the first covering end 252 and second and cover end
253.The periphery of the plug casing 21 is inserted in the front end of the spring 24 from the plug casing 21, and the sleeve 25 is subsequent certainly
The spring 24 is inserted in and is compressed in the front end of the plug casing 21, and the first internal projecting ring 251 of the sleeve 25 contacts described insert
The outer surface of casing 21, first covering end 252 are covered in the spring 24 and first outer 211 outside of bulge loop.Institute
It states sleeve 25 and compresses the spring 24 until described second covers end 253 not in the covering locating slot 213, at this point, will be described
The locating ring 26 of rigidity is inserted in the locating slot 213, and loosening sleeve 25 makes its no longer compressed spring 24, at this point, the spring
24 are limited between the described first outer bulge loop 211 and first internal projecting ring 251, the front end quilt of first internal projecting ring 251
The limit of locating ring 213 is so that the sleeve will not fall off from the plug casing 21.
Please continue to refer to shown in Fig. 2, Fig. 3, Fig. 5, the socket 3 includes Socket casing 31, is inserted in the Socket casing
Socket insulator 32 in 31, the female terminal 33 being inserted in the socket insulator 32 and it is installed on the Socket casing
The seal assembly 37 of 31 rear ends.
The Socket casing 31 is hollow to form the second cavity 315 for planting the socket insulator 32, the Socket casing
31 include the second outer bulge loop 311 formed from the 31 periphery protrusion of Socket casing, positioned at the described second outer 311 front end of bulge loop
Insertion section 312, the external screw thread 314 for being formed in 31 tail portion of Socket casing and rolling are fixed on the insertion section 312
Ball 313.It is equipped with annular groove 316 inside the second outer bulge loop 311, water proof ring 317, institute are installed in the annular groove 316
It states and is in close contact the water proof ring 317 after plug casing 21 is inserted into waterproof.
The ball 313 perpendicular on 312 direction of insertion section move and can roll.The ball 313 it is straight
Diameter is greater than the thickness of the insertion section 312.
The outer surface of the plug casing 21 and the first of the sleeve 25, which cover to be formed between end 252, supplies the socket shell
The gap 28 that the insertion section 312 of body 31 is inserted into.
The plug 2 and the socket 3 to it is slotting when, the insertion section 312 of the socket 3 is in the outer of the plug casing 21
Surface promotes backward, and the ball 313 rolls on the outer surface of the plug casing 21, at this point, the protrusion of the ball 313
In the outer surface of the insertion section 312.With the propulsion of the insertion section 312, the ball 313, which finally pushes, squeezes the sleeve
25, so that the sleeve 25 is squeezed the spring 24 backward until the ball 313 is fallen on 21 outer surface of plug casing
In ball grooves 212, at this point, the ball 313 no longer protrudes from the outer surface of the insertion section 312, the sleeve 25 is described
312 outer surface of insertion section described in the restoring force effect lower edge of spring 24 recoils to initial position, as a result, covers the sleeve 25
Above the ball 313 of the insertion section 312, the ball 313 can not move upwards that the ball 313 is made to be fixed on rolling
In pearl slot 212, so that the plug 2 be made to connect with socket 3；
When needing to separate the plug 2 with socket 3, it is only necessary to pull the sleeve 25 to the caudal directions of socket 3, make
The sleeve 25 is no longer covered in 313 top of ball, at this point, the plug 2, which continues rearwardly direction, applies strength
The plug 2 is separated with socket 3.
Compared to the previous snap close mode using traditional snap, the plug-type locking connector component of the application passes through
Ball 313 is setting up certain floating space perpendicular to 313 side of insertion section, and ball 313 is made to roll into the ball grooves
After in 212, the ball 313 is covered or be detached from by sleeve 25, limits the ball 313 in the ball grooves 212 or releasing
It puts the ball 313 and skids off ball grooves 212, to realize the locking and disengaging of plug and socket, locking and disengaging are simple and convenient,
And locking is more stable reliable.
The plug 2 with socket 3 be it is revocable, the plug 2 is also possible to socket, and the socket 3 is also possible to insert
Head.
Emphasis is refering to the seal assembly 27,37 shown in Fig. 2, Fig. 3, Fig. 5, being installed on the plug 2 and socket 3 in principle
Upper almost the same, its principle and structure is discussed in detail with the seal assembly 37 on socket 3 in the application:
