[0036] In order to enhance the stability of the connection between the connecting plug 1 and the connecting head 11, a rotating block 22 and other components are provided. When the connecting plug 1 moves backward, the housing 2 and the front plug block 211 thereon are driven to move backward. When the front plug block 211 is inserted into the upper inner part of the rear housing 2, the rear plug block 21 is also inserted into the lower inner part of the front housing 2. Moreover, the front plug block 211 squeezes the two rotating blocks 22 at the rear, and the rear plug block 21 squeezes the two rotating blocks 22 at the front, so that the rotating blocks 22 rotate, and the tension spring 24 is stretched.

The two rotating blocks 22 on the right side fit together and then rotate to lock the two outer shells 2 on the right side with each other. By locking the outer shells 2, the stability of the connection between the connecting plug 1 and the connecting head 11 can be enhanced. If the connecting plug 1 and the connecting head 11 need to be disconnected, the pull block 25 is held and the pull rope 23 is pulled. The pull rope 23 drives the rotating block 22 to rotate to the side away from the tension spring 24. The tension spring 24 is stretched, and the rotating block 22 can release the outer shell 2 after rotation. In this way, people can move the connecting plug 1 forward and reset it, thereby making the front plug block 211 move forward and reset it, and then release the pull block 25. Under the action of the tension spring 24, the rotating block 22 is driven to reverse and reset, and the pull rope 23 and the pull block 25 are driven to move and reset.

[0037] like Fig.10As shown, it also includes a guide block 3, a mounting frame 31 and a guide wheel 32. The left and right sides of the top and bottom of the connector 11 are connected to the guide blocks 3, and the left and right sides of the top and bottom of the connector 1 are connected to a group of mounting frames 31. Each group is provided with symmetrically arranged mounting frames 31. The guide block 3 is inserted between each group of mounting frames 31. The mounting frames 31 are rotatably connected to three guide wheels 32, and the guide wheels 32 and the guide blocks 3 are squeezed together.

[0038] When the connecting plug 1 moves backward, it will drive the mounting frame 31 and the guide wheel 32 to move backward. When the guide wheel 32 contacts the guide block 3, the guide wheel 32 will rotate. Under the action of the guide wheel 32, the resistance of the connecting plug 1 to move backward can be reduced, so that the connecting plug 1 can be more smoothly and quickly docked with the connector 11.

[0039] like Figure 11-Figure 12 As shown, it also includes a support plate frame 4, an elastic pressure ring 41 and an extrusion assembly. The connecting plug 1 and the connecting head 11 are both provided with a support plate frame 4.

The left and right sides of the support plate frame 4 are connected with elastic pressure rings 41 for pressing the wires. The support plate frame 4 is provided with an extrusion assembly for extruding the elastic pressure ring 41; the extrusion assembly includes a screw rod 42, a wedge block 43, a handle 44 and a top block 45. The support plate The sides of the frames 4 that are away from each other are slidably connected with wedge blocks 43, the left and right sides of the support plate frames 4 are slidably connected with top blocks 45, the top blocks 45 and the wedge blocks 43 are squeezed together, the top blocks 45 and the elastic pressure rings 41 are squeezed together, the sides of the support plate frames 4 that are away from each other are rotatably connected with screw rods 42, the screw rods 42 and the wedge blocks 43 are threadedly connected, and the ends of the screw rods 42 that are away from each other are fixed with rotating handles 44, the screw rods 42 are driven to rotate by the rotating handles 44, and the screw rods 42 drive the wedge blocks 43 to move.

Therefore, an elastic pressure ring 41 is provided to reinforce the position of the wire. The turning handle 44 can be manually rotated, and the rotation of the turning handle 44 drives the screw rod 42 to rotate. The rotation of the screw rod 42 drives the wedge block 43 to move to the side close to each other, and the wedge block 43 squeezes the top block 45, and drives the top block 45 to squeeze the elastic pressure ring 41. In this way, the elastic pressure ring 41 can clamp the wire, thereby strengthening the fixation of the wire. If there is no need to reinforce the wire, the turning handle 44 can be manually reversed, and the turning handle 44 drives the screw rod 42 to reverse, and the screw rod 42 drives the wedge block 43 to move to the side away from each other to reset and release the top block 45, and the elastic pressure ring 41 recovers and pushes the top block 45 to reset.

[0042] In order to enhance the stability of the connection between the connecting plug 1 and the connector, a second card block 54 and other components are provided. When the connecting plug 1 moves backward, it drives the support plate frame 4 and the groove block 5 thereon to move backward. The groove block 5 is inserted into the middle position of the rear support plate frame 4. After the connecting plug 1 and the connector 11 are docked, the magnetic block 17 moves forward to drive the piston rod to move upward. The piston rod discharges the gas into the expansion block 55 through the air guide pipe 53. The expansion block 55 automatically expands and pushes the second card block 54. The second card block 54 moves and snaps into The groove block 5 can be clamped in the groove of the groove block 5 by the second clamping block 54, thereby improving the stability of the connection between the connecting plug 1 and the connector.
