[0002] PLC distribution cabinet refers to a programmable control cabinet, and a control cabinet refers to a complete set of control cabinets, which are electrical cabinets that can control motors and switches.

[0003] For example, the authorization announcement number is "CN221305263U", which is a PLC distribution cabinet that is easy to arrange cables. Different cables can be adjusted in position or removed as needed to facilitate subsequent maintenance and inspection. Multiple sets of cable bundling mechanisms can be installed on each cable guide rail, and each cable bundling tube can be operated independently. This modular design makes system expansion and upgrading easier to adapt to different application requirements. However, in the use of the PLC distribution cabinet, the size of the cable opening is fixed, and for easy operation, the wires connecting the two electrical components cannot be pulled too tight. Although this facilitates cable arrangement, it may cause the wires to swing in the gap, causing the wires and the internal edges of the slots to wear, resulting in damage to the wires inside the PLC distribution cabinet and shortening the service life of the PLC distribution cabinet.

[0020] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0021] See also Figure 1-6: In this embodiment, a PLC distribution cabinet that is convenient for wiring includes a box body 1 and a door panel 4. The left and right front sides of the box body 1 are respectively connected to the inner side of the door panel 4 for rotation. The door panel 4 is rotated by the hinges on the left and right front sides of the box body 1. The left and right sides of the inner wall of the box body 1 are respectively fitted with protrusions 5, and the inner side of the protrusion 5 is fixed with a vertical plate 7. The front of the vertical plate 7 is connected to a fixed structure 2, and a plurality of blocking structures 3 are connected to the lower part of the outer wall of the box body 1.

[0022] The fixing structure 2 includes a horizontal plate 201 and screw rods 202. The rear end face of the horizontal plate 201 is fixedly connected to the front face of the vertical plate 7. The front face of the horizontal plate 201 is threadedly connected to the outer walls of multiple screw rods 202. The screw rods 202 are subjected to force to rotate back and forth through the front face of the horizontal plate 201. The outer wall of the screw rods 202 is rotatably connected to a curved plate 203 at the rear. The outer wall of the screw rods 202 is subjected to force to rotate through the front bearing of the curved plate 203. The outer wall of the curved plate 203 fits into the outer wall notch of the horizontal plate 201. The front face of the screw rods 202 is fixedly connected to a handle 204, which facilitates the rotation of the screw rods 202.

[0023] The handle 204 in the fixed structure 2 drives the screw 202 to rotate backward through the horizontal plate 201. The rotating screw 202 causes the curved plate 203 to move backward through the inner wall of the horizontal plate 201, so that the horizontal plate 201 fixes the wire behind the groove on the outer wall of the horizontal plate 201. The horizontal plate 201 fixes the wire to prevent shaking and friction, avoids damage to the wires inside the PLC distribution cabinet, and ensures the service life of the PLC distribution cabinet.

[0024] The outer wall of the protrusion 5 is threadedly connected with a bolt 6, and the outer wall end of the bolt 6 is threadedly connected to the inner wall of the box body 1. A plurality of electrical components 8 are fixed to the front of the vertical plate 7. The model of the electrical component 8 is selected according to the use requirements. A bracket 9 is fixed to the lower part of the inner wall of the box body 1. The blocking structure 3 includes a straight rod 301 and a circular plate 302. The rear end face of the straight rod 301 is fixed to the lower part of the outer wall of the box body 1, and the front face of the straight rod 301 is fixed to the rear end face of the circular plate 302. The outer wall of the straight rod 301 is plugged with a sleeve plate 303. The sleeve plate 303 is subjected to force to move back and forth on the outer wall of the straight rod 301. The bottom of the sleeve plate 303 is fixed with a round block 304. The round block 304 is made of rubber, and the rear of the outer wall of the round block 304 is plugged into the circular mouth of the outer wall of the box body 1.

[0025] Working principle:

[0026] PLC distribution cabinet assembly:

[0027] The wires are first passed through the slots on the outer wall of the horizontal plate 201, so that the two ends of the wires are respectively connected to the electrical components 8 on the front of the vertical plate 7. Then the handle 204 rotates backward with the screw 202 through the horizontal plate 201. The rotating screw 202 causes the curved plate 203 to move backward through the inner wall of the horizontal plate 201, so that the horizontal plate 201 fixes the wires behind the slots on the outer wall of the horizontal plate 201. The wires are fixed by the horizontal plate 201 to prevent shaking and friction, which facilitates the wiring of the wires. Then the vertical plate 7 is placed in the box body 1. At this time, the outer side of the protrusion 5 on the outer wall of the vertical plate 7 is in contact with the inner wall of the box body 1. Then the bolt 6 is threaded through the protrusion 5 and is threadedly connected to the inner wall of the box body 1 to complete the installation of the vertical plate 7. Then the wires connected to the bottom of the lowest electrical component 8 are uniformly passed through the bracket 9 for aggregation.

[0028] PLC distribution cabinet wires outside:

[0029] Divide the wires passing through the bracket 9 into five large bundles, and then tie them together with a rubber sleeve. Then, slide the sleeve 303 on the outer wall of the straight rod 301, so that the sleeve 303 and the round block 304 gradually separate from the circular opening on the outer wall of the box body 1. Then, rotate the sleeve 303 upward on the outer wall of the straight rod 301, so that the sleeve 303 and the round block 304 rotate upward. Then, pass the bundled wires through the circular opening inside the box body 1, and then connect the wires to the external connection position. Then flip the door panel 4 inward to complete the closing of the box body 1. Example 2

[0030] See also Figure 1-6 : In this embodiment, a PLC distribution cabinet that is convenient for wiring also includes a square frame 10, and the outer wall of the square frame 10 is fixedly connected to the inner wall of the bracket 9.

[0031] Working principle:

[0032] After the wire passes through the bracket 9, the frame 10 protects the wire through its own rubber material to prevent the wire from bending and passing through the round opening of the box 1 and causing the outer skin to be damaged.

[0033] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
