In the moving process of the carrier, the carrier can make the connector in a shaking state for a long time due to the movement of the carrier, so that stretching, extruding or radial bending force is caused to the connecting position of the connector.
When a user connects the cables of the carrier by using the device, the ends of two wires to be connected are respectively fixed in the through holes in the middle parts of the male shell 1 and the female shell 2, then the male shell 1 is held by the user to drive the plug connector 3 to be inserted into the female shell 2 together until the bottom of the thread plate 5 contacts with the top of the thread sleeve 6, at the moment, the user rotates the thread sleeve 6 while continuing the above-mentioned insertion action, so that the male shell 1 is continuously inserted into the female shell 2 until the bottom surface of the male shell 1 contacts with the top surface of the female shell 2, and the first sealing ring 4 in the first sealing groove 201 is extruded together, so that the first sealing ring 4 is deformed to achieve the sealing effect, and the basic sealing connection is completed.

As shown in fig. 6-8, the second limiting part 1102 is an arc-shaped ring surface curved towards the mother head shell 2, a gap is reserved between two adjacent second limiting parts 1102, so that the second limiting parts 1102 are easier to deform due to extrusion at the curved part of the middle part, an arc-shaped part 205 is arranged at the lower side in the mother head shell 2, the arc-shaped part 205 is used for extruding the curved part at the middle part of the second limiting parts 1102, the extrusion barrel 11 and the mother head shell 2 are in extrusion fit through the second limiting parts 1102 and the arc-shaped part 205, after the extrusion barrel 11 moves downwards and the second limiting parts 1102 are contacted with the arc-shaped part 205, the inner diameter of the arc-shaped part 205 is reduced from top to bottom, and accordingly, the second limiting parts 302 are arranged at the lower side outside the plug connector 3, the second limiting parts 1102 are in limit fit with the second limiting parts 302, when the curved part of the middle part of the second limiting parts 1102 is extruded inwards by the arc-shaped part 205, the bottom of the second limiting parts 1103 is close to the second limiting parts 302 due to deformation, and then the limiting parts 302 are limited, when the vertical distance from the middle part 301 to the top of the second limiting parts 302 is equal to the second limiting parts 1102, and the vertical distance from the top to the top of the second limiting parts 302 is not equal to the second limiting parts 302, and the vertical to the top of the second limiting parts 302 is enabled to be larger than the second limiting parts of the second limiting parts 302, and the vertical to be more than the vertical to the second limiting parts of the second limiting parts 302, and the second limiting parts are not to be deformed to the second limiting parts 302, and the second limiting parts are enabled to be in the second limiting parts are deformed, and are deformed.
The existing connector is screwed up the male and female heads through the screw threads, and the rubber sealing ring is deformed to a certain extent by the axial extrusion force generated by screwing up, so that the sealing effect is achieved, but under the environment of long-term vibration or certain pressure intensity, the screw threads are gradually loosened, so that the sealing effect is weakened, the device is sealed without depending on the axial extrusion force of screw thread screwing up, and the stable sealing effect is achieved by the deformation extrusion force between objects, and the specific process is as follows:
on the basis of the basic sealing connection process, when the male head shell 1 is inserted into the female head shell 2, the male head shell 1 drives the plug connector 3 to move downwards and enable the second protruding portion 302 to pass through the extrusion barrel 11 until the first protruding portion 301 extrudes the middle portion of the extrusion barrel 11 and the second sealing ring 12, the outer wall of the first protruding portion 301 is completely attached to the middle portion of the inner wall of the extrusion barrel 11, and the first protruding portion 301 and the extrusion barrel 11 jointly extrude the second sealing ring 12 to deform so that the extrusion barrel 11 and the plug connector 3 are kept sealed.
In the above process, the extrusion barrel 11 is extruded by the first protruding portion 301 to generate expansion deformation, so that the third sealing groove 1104 drives the third sealing ring 13 to expand outwards, so that the third sealing ring 13 extrudes the inner wall of the female head shell 2, and therefore, the extrusion barrel 11 and the female head shell 2 are kept sealed, and the integrity of sealing is ensured through inner and outer bidirectional sealing.
When the outer wall of the first protruding portion 301 is fully attached to the middle portion of the inner wall of the extrusion barrel 11, the first protruding portion 301 is fully contacted with the friction strip 14, so that large static friction force is generated between the plug connector 3 and the extrusion barrel 11, then the plug connector 3 drives the extrusion barrel 11 to move downwards together through friction force until the cambered surface between the second limiting portion 1102 and the third sealing groove 1104 on the extrusion barrel 11 contacts the arc-shaped portion 205 of the inner wall of the female head shell 2, and as the extrusion barrel 11 moves downwards continuously, the cambered surface between the second limiting portion 1102 and the third sealing groove 1104 on the extrusion barrel 11 is extruded by the arc-shaped portion 205 of the inner wall of the female head shell 2 to be bent towards the plug connector 3 until the bottom of the second limiting portion 1102 contacts the top of the second protruding portion 302, the extrusion barrel 11 does not move downwards any more, and the plug connector 3 is axially limited.
In the above process, the first limiting portion 1101 is attached to the inner wall of the female head shell 2 and contacts with the adjacent limiting groove 204 in the downward moving process, and as the extrusion barrel 11 moves downward, the first limiting portion 1101 repeatedly generates micro deformation and slides relatively with the adjacent limiting groove 204, so that the first limiting portion slides relatively with the limiting groove 204 adjacent to the lower side, when the extrusion barrel 11 does not move downward any more, the female head shell 2 limits the extrusion barrel 11 unidirectionally through the adjacent limiting groove 204 and the first limiting portion 1101, so that the extrusion barrel 11 keeps an extruded state and cannot move axially, the effect that the female head shell 2 limits the male head shell 1 axially is achieved, and the stability of connection is improved.
