[0003] The patent specification with announcement number CN206076767U discloses a switch status monitoring device for a power distribution cabinet, including a plurality of reflective photoelectric switch sensors and a thin film circuit board. The reflective photoelectric switch sensors are connected one by one to the thin film circuit board. The thin film circuit board is provided with wiring sockets. The number of wiring sockets corresponds to the reflective photoelectric switch sensors one by one. The wiring sockets are connected to a switch quantity acquisition module. The reflective photoelectric switch sensors are arranged one by one under a switch handle with a reflective light characteristic. The switch handle is pulled down to turn on the reflective photoelectric switch sensor. Since the device sets the communication line as a thin film circuit board, it has a small size and does not monitor the switch on and off state through linkage. Therefore, there is no need to use accessories in the prior art, making the structure more compact. The utility model sticks the monitoring device under the switch handle, which greatly simplifies the installation process and is easy to use.

[0004] However, in the implementation of relevant technologies, it was found that the switch status monitoring device of a distribution cabinet designed as above has the following problems: in the prior art, the switch status is monitored by components such as reflective photoelectric switch sensors, but in actual use, the connection of the line also needs to be monitored. If the line becomes loose or detached, it will affect the connectivity of the circuit system at the least, and may cause a short circuit or even a fire at the worst. In view of this, a low-voltage distribution cabinet with line status monitoring is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a low-voltage distribution cabinet with line status monitoring.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a low-voltage power distribution cabinet with line status monitoring, comprising a cabinet body, an electrical equipment body is installed inside the cabinet body, and a monitoring mechanism is arranged at the bottom end of the electrical equipment body;

[0007] The monitoring mechanism includes a support frame, which is installed at the bottom end of the electrical equipment body, and a limit plate is fixed below the axial outer wall of the support frame, a first damping spring is embedded in the top of the limit plate, and the support plate is connected above the first damping spring, a ring is slidably connected inside the support plate, and a spring sheet is fixed on the top of the ring, a fastening ring is provided on the outside of the spring sheet, a pressure sensor is embedded on one side of the first damping spring at the top of the limit plate, and the limit plate is used to facilitate the limiting of the connecting cables to avoid clutter, and at the same time, the fixed position of the support frame corresponds to the plug position of the electrical equipment body.

[0008] As a further description of the above technical solution: the size of the limiting plate is consistent with the size of the supporting plate, and a sliding structure is formed between the supporting plate and the ring. The ring is limited by the supporting plate to avoid excessive shaking, and slides along the supporting plate to facilitate disassembly and assembly.

[0009] As a further description of the above technical solution: the ring is threadedly connected to the fastening ring, and the fastening ring fits tightly against the spring sheet. After the cable passes through the ring, the threaded fastening ring presses the spring sheet to clamp and fix the cable, and prevents it from detaching under the limit of the supporting plate.

[0010] As a further description of the above technical solution: the front end of the cabinet is movably connected to a door panel, and the inner bottom end of the cabinet is provided with a connecting groove, which facilitates the connection cables to enter the interior of the cabinet and connect with the main body of the electrical equipment.

A plurality of limit rings, telescopic springs and clamping plates are provided, and correspond to the connecting sockets of the main body of the electrical equipment.

[0014] The utility model has the following beneficial effects:

[0015] The utility model designs a low-voltage power distribution cabinet with line status monitoring. After the cable is connected by means of a sleeve, a threaded fastening ring is used to compress a spring sheet to fix it on the cable. The sleeve and the fastening ring are elastically pushed by a first damping spring to allow a supporting plate and an electrical equipment body to clamp the sleeve and the fastening ring, thereby maintaining stability and avoiding loosening. When looseness occurs, the sleeve and the fastening ring are misaligned, thereby compressing the supporting plate and allowing the supporting plate to touch a pressure sensor, thereby reminding a control end of the low-voltage power distribution cabinet to issue an early warning to avoid danger.

[0023] As a further implementation scheme of the above technical scheme: the size of the limiting plate 302 is consistent with the size of the supporting plate 304, and a sliding structure is formed between the supporting plate 304 and the ring 305. The ring 305 is limited by the supporting plate 304 to avoid excessive shaking, and slides along the supporting plate 304 to facilitate disassembly and assembly.

[0024] As a further implementation scheme of the above technical scheme: the ring 305 is threadedly connected with the fastening ring 307, and the fastening ring 307 fits tightly with the spring sheet 306. After the cable passes through the ring 305, the threaded fastening ring 307 presses the spring sheet 306 to clamp and fix the cable, and prevents it from detaching under the limit of the supporting plate 304.

[0025] During the specific implementation, first, the ring 305 is connected with the spring sheet 306 and the fastening ring 307 and the connecting cable. At the same time, the ring 305 is in contact with the supporting plate 304 and is connected to the electrical equipment body 2. The first damping spring 303 is supported by the limit plate 302 to elastically push the supporting plate 304, so that the ring 305 and the fastening ring 307 are clamped between the electrical equipment body 2 and the supporting plate 304, thereby achieving a clamping and fixing effect to avoid loosening and detachment. If detachment occurs, the ring 305 is misplaced and in contact with the supporting plate 304, thereby compressing the first damping spring 303 and touching the pressure sensor 308.

A clamping plate 608 is fixed to one end of the telescopic spring 607. The clamping plate 608 is pushed by the telescopic spring 607 to press the connecting cables onto the mounting frame 601, which plays a role in preliminary limiting and arranging the connecting cables to avoid clutter.

[0029] As a further implementation scheme of the above technical scheme: the limiting rings 606 are evenly distributed at equal distances about the top of the mounting frame 601, and the limiting rings 606 are elastically connected to the clamping plate 608 through the telescopic spring 607. A plurality of limiting rings 606, telescopic springs 607 and clamping plates 608 are provided, and correspond to the connecting sockets of the electrical equipment body 2.

[0030] In specific implementation, after the connecting cable enters the cabinet 1 from the connecting slot 5, it passes through the limiting ring 606. Under the elastic push of the telescopic spring 607, the pressing plate 608 is clamped to play a preliminary limit to avoid shaking and entanglement. The two movable plates 602 connected by the mounting frame 601 are rotated, a fixed support rod 603, and a fixed connecting tube 605. The support rod 603 and the connecting tube 605 are elastically pushed and connected by the second damping spring 604, so that the mounting frame 601 can be disassembled by pressing the movable plate 602 to break away from the resistance and restriction of the connecting slot 5.
