Symmetrically arranged with respect to each other, the locking mechanism further includes a plurality of groups of limit strips 21 and a plurality of groups of first contact pieces 22. Both sides of the upper pressing plate 20 are fixedly connected to the same limit strips 21. The sides of the limit strips 21 are fixedly connected to the sliding blocks 23. The first contact piece 22 is located between the two limit strips 21. The first contact piece 22 is fixedly connected to the upper pressing plate 20. The first contact piece 22 is linearly arrayed with respect to the upper pressing plate 20. The locking mechanism further includes a plurality of groups of second contact pieces 25. The second contact piece 25 located on the surface of the lower pressing plate 24 is fixedly connected to the lower pressing plate 24. The second contact piece 25 is linearly arrayed with respect to the lower pressing plate 24. The cross-section of the second contact piece 25 is trapezoidal.

[0028] Specifically, when in use, the operator embeds the wire connector that needs to be fixed between the upper pressing plate 20 and the lower pressing plate 24, and fixes multiple groups of first contact pieces 22 on the surface of the upper pressing plate 20, and fixes multiple groups of second contact pieces 25 on the surface of the lower pressing plate 24. The upper pressing plate 20 and the lower pressing plate 24 are close to each other to clamp the wires, and the contact area with the surface of the wires is increased by the provision of the first contact piece 22 and the second contact piece 25, thereby increasing the friction of the wires, improving the firmness of the wires, preventing the wires from accidentally falling off, reducing safety risks, reducing the occurrence of safety accidents, ensuring that the wires are safely and reliably connected inside the distribution box, and preventing them from loosening or disconnecting.

[0029] like Figure 2 - Figure 5 As shown, the locking mechanism also includes multiple groups of sliding blocks 23, and the inner wall surface of the locking terminal 12 is provided with a sliding guide groove 16 adapted to the sliding block 23, the sliding block 23 is embedded in the sliding guide groove 16 and is slidably connected to the locking terminal 12, and both sides of the upper pressing plate 20 are fixedly connected to the same sliding block 23, and the locking mechanism also includes multiple groups of bolts 17, and the top surface of the locking terminal 12 is provided with a penetration hole 13 adapted to the bolt 17, the penetration hole 13 passes through the penetration hole 13 and is threadedly connected to the locking terminal 12, one end of the bolt 17 is connected to the upper pressing plate 20, and the locking mechanism also includes multiple groups of springs 19, the spring 19 is embedded in the insertion hole 14, one end of the spring 19 is fixedly connected to the locking terminal 12, and the other end of the spring 19 is fixedly connected to the lower pressing plate 24.

[0030] Specifically, when in use, the operator embeds the wire between the upper pressing plate 20 and the lower pressing plate 24, and rotates by twisting the bolt 17. The rotating bolt 17 pushes and presses the upper pressing plate 20. The upper pressing plate 20, which is pushed by the bolt 17, pushes the sliding block 23 to move along the path of the sliding guide groove 16 toward the surface of the lower pressing plate 24. The lower pressing plate 24 is elastically connected to the lock terminal 12 through the spring 19. When the bolt 17 rotates and pushes and presses the upper pressing plate 20, the first contact piece 22 presses the wire and is in close contact with the second contact piece 25. At the same time, the second contact piece 25, which is pressed by the first contact piece 22, transmits the pressure to the spring through the lower pressing plate 24. Spring 19, spring 19 will give an elastic force to the lower pressing plate 24, and the wire will be clamped by the elastic force given by the second contact piece 25 and the thrust given by the bolt 17 to the first contact piece 22. During operation, when the bolt 17 becomes loose, the spring 19 will push the lower pressing plate 24. The lower pressing plate 24 under thrust will squeeze the wire through the second contact piece 25 to contact the first contact piece 22 on the surface of the upper pressing plate 20, so as to avoid the wire from loosening and falling off due to the loosening of the bolt 17, thereby ensuring the normal operation of the machine, reducing the workload of the staff, improving the working efficiency of the machine, ensuring that the wires are safely and reliably connected inside the distribution box, and preventing them from loosening or disconnecting.

[0031] like Figure 2 and Figure 3 As shown, the locking mechanism further includes a plurality of rubber plugs 18 . The surface of the locking terminal 12 is provided with a snap-fitting groove 15 adapted to the rubber plug 18 . The rubber plug 18 is embedded in the snap-fitting groove 15 and snap-fitted with the locking terminal 12 .

[0032] Specifically, when in use, the operator passes the wire through the rubber plug 18, and the wire passing through one end of the rubber plug 18 is connected to the lock terminal 12. By setting the rubber plug 18 to be engaged with the lock terminal 12, the operator can replace the rubber plug 18 according to the usage. At the same time, the rubber plug 18 is set to improve the sealing of the wiring on the surface of the lock terminal 12, prevent dust, moisture and other impurities from entering the interior of the lock terminal 12, protect the wires and connecting parts from damage, extend the service life of the electrical components, and reduce the cost expenditure of the enterprise.

[0033] Working principle: the operator passes the wire through the rubber plug 18, and the wire passing through one end of the rubber plug 18 is connected to the lock terminal 12. The rubber plug 18 is set to engage with the lock terminal 12. The operator can replace the rubber plug 18 according to the usage. At the same time, the rubber plug 18 is set to improve the sealing of the wiring on the surface of the lock terminal 12 to prevent dust, moisture and other impurities from entering the interior of the lock terminal 12. The operator embeds the wire between the upper pressing plate 20 and the lower pressing plate 24, and rotates by twisting the bolt 17. The rotating bolt 17 pushes and presses the upper pressing plate 20. The upper pressing plate 20, which is pushed by the bolt 17, pushes the sliding block 23 to move along the path of the sliding guide groove 16 toward the surface of the lower pressing plate 24. The lower pressing plate 24 is elastically connected to the lock terminal 12 through the spring 19. When the bolt 17 rotates and pushes and presses the upper pressing plate 20, the first contact piece 22 presses the wire to make close contact with the second contact piece 25, and is simultaneously pressed by the first contact piece 22. The second contact piece 25 under the pressure of the contact piece 22 will transfer the pressure to the spring 19 through the lower pressing plate 24, and the spring 19 will give the lower pressing plate 24 an elastic force. The wire is clamped together by the elastic force given by the second contact piece 25 and the thrust given to the first contact piece 22 by the bolt 17. During operation, when the bolt 17 becomes loose, the spring 19 at this time will push the lower pressing plate 24, and the lower pressing plate 24 under the thrust will squeeze the wire through the second contact piece 25 to contact the first contact piece 22 on the surface of the upper pressing plate 20. The operator will embed the wire connector to be fixed between the upper pressing plate 20 and the lower pressing plate 24, and fix multiple groups of first contact pieces 22 on the surface of the upper pressing plate 20, and fix multiple groups of second contact pieces 25 on the surface of the lower pressing plate 24. The upper pressing plate 20 and the lower pressing plate 24 are close to each other to clamp the wire, and the contact area with the surface of the wire is increased by the first contact piece 22 and the second contact piece 25, thereby increasing the friction of the wire.
