[0029] Claims 1-9 A method for using a cable connection box for a power supply cable, comprising the following steps: S1: When the cable conductors are combed and limited, the cable conductors can be driven to be pressed into the top block 25, so that the top block 25 slides in the spring groove 23 and compresses the first spring 24. At the same time, the top block 25 drives the limit block 26 to slide on the outer wall of the specific guide rod 29 in the first slider 28. Under the elastic force of the first spring 24, the cable conductor is limited on the inner wall of the fixed block 22. Then, one end of several cable conductors limited in the top block 25 is fixed on the specific copper bar 211. When it is necessary to remove several conductors from the fixed block 22, the dial button 210 can be turned to drive the first slider 28 to slide rightward in the slide groove 27, so that the inner wall of the first slider 28 contacts several limit blocks 26. The limit block 26 drives the top block 25 to slide in the spring groove 23 and compresses the first spring 24, so that several cable conductors limited by the top block 25 are synchronously detached.

[0030] S2: When the bottom plate 21 needs to be taken out from the connection box 1, the bottom plate 21 can be supported to drive the receiving columns 32 fixed by the two fixed blocks 22 on the bottom plate 21 to slide upward from the receiving blocks 31 in the connection box 1 so that the receiving columns 32 are separated from the receiving blocks 31. Then, the bottom plate 21 is horizontally taken out from the connection box 1. When the current of the cable conductor is overloaded, the switch of the electromagnetic release 34 jumps to cut off the current.

[0031] S3: When the switch door 41 needs to be opened, the torsion spring 410 drives the flip block 49 to be stuck in the fixed groove 411 in the normal state, and the pull rod 44 can be pulled to drive the connecting block 45 to slide upward in the connecting groove 43, and the connecting block 45 drives the guide block 47 to slide upward in the reserved groove 46, so that the second slider 412 is limited by the flip block 49 and the flip column 48 and slides along the arc flipping trajectory of the flip block 49 in the guide block 47, and the guide block 47 drives the flip block 49 to flip around the flip column 48 through the second slider 412, and the flip block 49 flips to the torsion spring 410. The spring 410 applies a force to make the torsion spring 410 elastically deform, and the flip block 49 flips and disengages from the fixed groove 411. The handle 42 can be grasped to drive the switch door 41 to flip around the hinge to open the connection box 1. When the switch door 41 needs to be closed and locked, the switch door 41 is first flipped to seal the connection box 1, and then the pull rod 44 is released. Under the elastic recovery of the torsion spring 410, the flip block 49 flips and slides into the fixed groove 411 to complete the fixation. The synchronized second slider 412 drives the connection block 45 and the pull rod 44 to slide into the connection groove 43 along the arc trajectory through the guide block 47.

[0032] A specific application of this embodiment is: the electromagnetic release 34 is a type of release that provides short-circuit protection. When the current is large enough, the magnetic field force generated overcomes the reaction force spring to attract the armature to hit the traction rod, thereby driving the mechanism to cut off the circuit. When there is no fault in the circuit, the current passes through the coil of the electromagnetic release, and the magnetic field generated in the coil is weak and cannot attract the iron core or moving parts. At this time, the electromagnetic release remains in the "non-triggered" state, the circuit continues to work normally, and the current is transmitted through the circuit breaker. When the current exceeds the set safety value, the coil current in the electromagnetic release increases, generating a stronger magnetic field. This magnetic field will generate sufficient suction to attract the iron core or moving parts, trigger the tripping mechanism, disconnect the contacts of the circuit breaker, and cut off the circuit. If a short-circuit fault occurs, the suction generated by the electromagnetic magnetic field in the electromagnetic release will also increase rapidly, immediately triggering the tripping mechanism, and quickly disconnecting the circuit to prevent the current from further increasing and causing equipment damage or fire.

[0033] By setting up the fixing mechanism 2, the maintenance personnel can first extend the main cable into the connection box 1 through the cable entry hole 214, and take out the bottom plate 21 from the connection box 1, drive the receiving columns 32 on the two fixing blocks 22 to detach from the receiving blocks 31, take out the bottom plate 21, and then perform diversion and combing to connect the specific cable wire with the electromagnetic release 34 in the protection mechanism 3, and then pass through the lower fixing block 22 to fix one end of the wire on the specific copper bar 211. At this time, the personnel can use bolts or twisted wires to fix one end of the wire on the copper bar 211, and then connect the wire that needs to be connected to the specific device and power it to the specific copper bar 2 11, through the outlet hole 213, at this time, the personnel can enter the specific top block 25 by pressing the lower side wire, so that the top block 25 is driven by the inclined force to slide into the spring groove 23 and compress the first spring 24. At this time, the top block 25 drives the limit block 26 to slide on the specific guide rod 29. After the lower side wire is pressed into the specific top block 25, it is subjected to the elastic force of the first spring 24, driving the top block 25 to press on the wire, so that the wire is limited on the fixed block 22, and a number of wires are combed and limited in the specific top block 25. The upper side wire is pressed into the upper side fixed block 22 in the same way to complete the limit fixation, and then drives the bottom plate 21 to slide the receiving column 32 into The receiving block 31 is installed in the connection box 1, and the wiring, combing and limiting functions are completed. When the wire line needs to be adjusted, the bottom plate 21 is taken out, and the first slider 28 is driven to slide to the right by turning the dial button 210, wherein the guide rod 29 plays a limiting role, so that the first slider 28 drives the top block 25 to compress the first spring 24 through the limiting block 26, and the wires in the top blocks 25 are taken out together, and the limiting is released. There is no need to take out the wires one by one, which is fast and convenient. The insulating block 212 is set to insulate the copper strip 211 from contacting the bottom plate 21, and to fix and support the copper strip 211 while preventing the copper strip 211 from contacting the bottom plate 21. The plate 21 may cause the current to flow out through the bottom plate 21 when the wires are connected, resulting in short circuit leakage and the like. By utilizing the elastic force of the first springs 24, maintenance personnel can press the cable wires into a specific top block 25 to comb and limit them, so that the lines on the bottom plate 21 can be arranged neatly. When the lines need to be adjusted, the bottom plate 21 can be taken out through the receiving block 31 and the receiving column 32, and the dial button 210 can be turned to synchronously take out the cable wires limited in the top block 25, so that the lines can be adjusted on the copper bar 211, and the combed lines can be limited and fixed. The simple and quick operation further improves the practicality of the device.

[0034] By setting up the protection mechanism 3 and a plurality of electromagnetic releases 34, the power supply wires can be prevented from being connected, so as to avoid a sudden increase in the current of the power supply wires causing current overload, etc., which may affect and damage the electrical equipment. The current overload can be disconnected in time to protect the electrical equipment. The fixing frame 33 can be fixedly supported by the plurality of electromagnetic releases 34, and the grounding wire 35 can be used to ground the possible trace leakage current on the bottom plate 21 and the fixing frame 33 to the outside through the grounding wire 35 to avoid electric shock caused by contact with the connection box 1. The power supply wires can be connected by a plurality of electromagnetic releases 34 to prevent current overload from affecting the power supply equipment. At the same time, the grounding wire 35 can be set to ground the possible leakage current in the device for protection, so as to avoid dangerous situations such as electric shock caused by accidental contact with the device. The protection performance of the device is enhanced to a certain extent, and the safety of the device is further improved.

[0035] By setting up the switch mechanism 4, the maintenance personnel can pull the pull rod 44 upward from the connecting groove 43 by grasping the handle 42, and drive the guide block 47 to slide upward in the reserved groove 46 through the connecting block 45. Since the second slider 412 of the flip block 49 slides in the guide block 47, the flip block 49 flips around the flip column 48 and drives the torsion spring 410 to elastically deform. When the connecting block 45 is pulled up to a certain extent, the guide block 47 drives the flip block 49 to flip through the second slider 412, and the front end of the flip block 49 is disengaged from the fixed groove 411. Then, the handle 42 is pulled to drive the switch door 41 to flip around the hinge between it and the connecting box 1 to expose the connecting box 1. When it is necessary to close the switch door 41 and the connecting box 1, the same principle is used to drive the switch door 41 to flip and close. Connecting box 1, and at the same time release the pull rod 44, and under the elastic force of the torsion spring 410, the flip block 49 is driven to flip, and slide into the fixed groove 411 to complete the airtight fixation between the switch door 41 and the connecting box 1, thereby realizing the utilization of the elastic deformation of the torsion spring 410. The maintenance personnel can pull the pull rod 44 and pull it outward, and drive the flip block 49 to flip around the flip column 48 through the sliding of the guide block 47 and the second slider 412, and disengage the right end of the flip block 49 from the fixed groove 411, so as to drive the switch door 41 to open the connecting box 1 to expose its interior for maintenance and adjustment of the line. The switch door 41 is closed and the pull rod 44 is released to seal the switch door 41 and the connecting box 1. The simple and quick switch operation reduces the occurrence of unexpected situations, further improving the practicality of the device.
