[0040] In this embodiment, the upper surface of the motion rod 920 is provided with an avoidance hole 926 and a groove 923, and the upper and lower surfaces of the end of the motion rod 920 away from the groove 923 are provided with an inclination angle 927. The front of the protective box 10 is provided with a rotating shaft 918, and one end of the rotating shaft 918 is rotatably connected to a rotating plate 919, and the groove 923 is adapted to the rotating plate 919.

[0041] The working principle of the present invention is: an automobile wiring harness connector, when in use, the user inserts the plug 6 as a whole into the interior of the fixed socket 5, so that the surface of the second sealing ring 7 is squeezed and contacted with the inner wall of the fixed socket 5, so that the left side of the plug 6 is squeezed and contacted with the right side of the contact plate 903, compressing the first return spring 902 to shorten, and during the movement of the plug 6, the front and rear sliders 912 are pulled to drive the two protective blocks 910 away from each other until the positioning head 914 passes through the limiting hole 906, when the left side of the plug 6 is squeezed and contacted with the right side of the contact plate 903, the positioning head 914 moves to the left side of the protective block 910, and the slider 912 is released. The protective block 910 is reset under the reset action of the second return spring 908. At this time, the left side of the protective block 910 is squeezed and contacted with the right side of the positioning head 914, and the protective block 910 limits the positioning head 914, thereby maintaining the stability of the plug 6 inserted in the fixed socket 5 and promoting the movement. The movable rod 920 slides along the inner wall of the mounting sleeve 921. During the movement of the movable rod 920, the surface of the inclined angle 927 contacts the inclined surface of the lower surface of the mounting force block 924, driving the mounting force block 924 in the upper and lower relative positions to slide away along the inner wall of the small hole 925, and the avoidance hole 926 avoids the third reset spring 928. At this time, the movement of the mounting force block 924 drives the lower arc pressure plate 929 to move, and the lower arc pressure plate 929 cooperates with the upper arc pressure plate 917 to fix the surface of the transmission line 8 and increase the surface friction with the transmission line 8. When the transmission line 8 is pulled by external force, the upper arc pressure plate 917 and the lower arc pressure plate 929 are provided with a silicone friction sheet on the opposite surface to prevent the transmission line 8 from being pulled and broken when it is in direct contact with the plastic shell. By means of the above structure, the fixed socket 5 and the plug 6 are prevented from being separated during use, and the transmission line 8 is prevented from being pulled and broken when it is in direct contact with the plastic shell.
