Once electrical components malfunction or the external ambient temperature rises abnormally, fire accidents can easily occur, posing a serious threat to the safety of people and property.
[0004] In view of the above problems, there is an urgent need for a new type of electrical cabinet wiring locking device to improve the stability and safety of electrical connections, while also meeting the requirements for fire protection and heat insulation. This device needs to securely lock the plug and slot together to prevent them from coming loose due to external forces, and also needs to have excellent fire protection and heat insulation performance to address potential fire risks. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where connectors easily detach from the slots when wire harnesses are subjected to external forces, affecting the stability of electrical connections. This invention provides a wiring locking device for electrical cabinets to solve the problems existing in the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An electrical cabinet wiring locking device is disclosed. The electrical cabinet includes an electrical cabinet partition, on which electrical components and mating electrical components are disposed. The electrical components are provided with slots, and the mating electrical components are provided with plugs. The plugs and slots are inserted into each other. The wiring locking device includes a first locking mechanism disposed on the electrical components and a second locking mechanism disposed on the plugs. When the plugs are inserted into the slots, the first locking mechanism and the second locking mechanism are inserted simultaneously to lock the wiring between the plugs and slots.
[0008] Further improvements to this technical solution include a first locking mechanism comprising a locking seat, the locking seat being mounted on an electrical component on one side of the slot, a guide telescopic rod being provided inside the locking seat, one end of the guide telescopic rod being fixed inside the locking seat, the other end of the guide telescopic rod extending outside the locking seat and connected to a locking block, a guide telescopic spring being sleeved on the guide telescopic rod, a locking port being provided at one end of the locking seat near the locking block, a guide sleeve being provided at the locking port, and the guide sleeve being perpendicular to the electrical component;

[0016] Further improvements to this technical solution include the installation of a positioning rod on the fireproof cover and a positioning sleeve on the electrical component that matches the positioning rod, with the positioning rod inserted into the positioning sleeve.
[0017] The beneficial effects of this utility model are as follows:
[0018] Improving the stability and safety of electrical connections: A secure connection between the plug and slot is achieved through the design of a first and second locking mechanism. During plug insertion into the slot, a locking plate pushes a locking block into the locking seat, and under the action of a guide spring, it pops out and engages, effectively preventing the plug from falling off due to external force, thus ensuring the stability and safety of the electrical connection.
[0019] Simplified operation and easy maintenance: This device is simple and convenient to operate. When it is necessary to separate the plug from the slot, simply press the locking block through the port, and the plug will easily pop out under the action of the auxiliary spring.

Detailed Implementation
[0029] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0031] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a wiring locking device for an electrical cabinet. The electrical cabinet includes an electrical cabinet partition 1, on which a plurality of electrical components 2 and a plurality of mating electrical components 3 are arranged. The electrical components 2 are provided with slots 21, and the mating electrical components 3 are provided with plugs 31. In use, the plugs 31 and slots 21 are plugged in. The wiring locking device for the electrical cabinet includes a first locking mechanism provided on the electrical components 2 and a second locking mechanism provided on the plugs 31. When the plugs 31 are plugged in and slots 21 are plugged in, the first locking mechanism and the second locking mechanism are plugged in simultaneously to lock the wiring between the plugs 31 and slots 21.
[0032] Specifically, the first locking mechanism includes a locking seat 221, which is mounted on an electrical component 2 on one side of the slot 21. A guide telescopic rod 222 is provided inside the locking seat 221. One end of the guide telescopic rod 222 is fixed inside the locking seat 221, and the other end extends outside the locking seat 221 and is connected to a locking block 225. A guide telescopic spring 223 is sleeved on the guide telescopic rod 222. A locking port is provided at the end of the locking seat 221 near the locking block 225, and a guide sleeve 224 is provided at the locking port, perpendicular to the electrical component 2. The second locking mechanism includes a main connector bracket 321, which is located at the end of the plug 31 away from the slot 21. A locking plate 322 is provided at the end of the main connector bracket 321 away from the plug 31. The plate 322 is provided with a bayonet, and guide blocks 323 are provided on the upper and lower sides of the bayonet. The guide blocks 323 are arranged parallel to the guide sleeve 224. In use, the guide blocks 323 are slidably installed in the guide sleeve 224. After the plate 322 presses the block 225 into the locking seat 221, the plate 322 and the block 225 abut against each other. Specifically, the block 225 will enter the locking seat 221 under the pressure of the plate 322. At this time, the guide telescopic spring 223 and the guide telescopic rod 222 will also be compressed. When the block 225 and the locking hole on the plate 322 are aligned, the block 225 will pop out from the locking seat 221 and lock into the locking hole of the plate 322 under the action of the guide telescopic spring 223, and abut against the plate 322, so that the plug 31 can be locked in the slot 21. In addition, the guide block 323, which is slidably installed inside the guide sleeve 224, can guide the movement of the clamping plate 322 and improve the stability of the movement of the clamping plate 322.
[0033] Furthermore, the first locking mechanism also includes a sleeve 226 and an auxiliary spring 227 disposed within the sleeve 226. The sleeve 226 is disposed on the side of the slot 21 away from the locking seat 221 and is vertically mounted on the electrical component 2. The second locking mechanism also includes an auxiliary connector 324, which is mounted on the end of the plug 31 away from the main connector 321. A pressure block 325 is disposed on the end of the auxiliary connector 324 away from the plug 31. In use, the pressure block 325 is inserted into the sleeve 226 and abuts against the auxiliary spring 227 within the sleeve 226. When in use, as the plug 31 is inserted into the slot 21, the pressure block 325 also enters the socket 226. At this time, the auxiliary spring 227 will be compressed. When it is necessary to separate the plug 31 from the slot 21, press the locking block 225 directly through the through port 331 and let the locking block 225 enter the locking seat 221. At this time, under the action of the auxiliary spring 227, the plug 31 will pop out from the slot 21, which facilitates the separation of the slot 21 and the plug 31.
[0034] Both the main connector frame 321 and the auxiliary connector frame 324 adopt U-shaped connector frames.
[0035] In order to provide fireproof and heat insulation for the plug 31 and the slot 21, the second locking mechanism is also provided with a fireproof cover 33, which is installed on the outside of the main connector bracket 321 and the auxiliary connector bracket 324.
[0036] like Figure 4 As shown, a passage 331 is provided on the fireproof cover 33. The passage 331 is located on the fireproof cover 33 at the locking port. An opening and closing control mechanism for the passage 331 is provided on one side of the fireproof cover 33. The opening and closing control mechanism for the passage 331 includes a sealing block 3321, an L-shaped bracket 3322, and a fixed shaft 3323. One end of the L-shaped bracket 3322 is fixed to the fireproof cover 33, and the other end of the L-shaped bracket 3322 is fixed to the fireproof cover 33 via the fixed shaft 3323. The sealing block 3321 is rotatably mounted on the fixed shaft 3323. A torsion spring 3324 is sleeved on the fixed shaft 3323. One end of the torsion spring 3324 is fixed to the sealing block 3321, and the other end of the torsion spring 3324 is fixed to the L-shaped bracket 3322. The operator can open the port 331 through the port 331 opening and closing control mechanism, and release the first and second locking mechanisms from locking the plug 31 and slot 21 through the port 331, thus separating the plug 31 and slot 21. The operation is convenient. Specifically, in order to control the opening and closing of the port 331, in the initial state, the sealing block 3321 is located in the position of the port 331, which can block the port 331. When it is necessary to separate the plug 31 and slot 21, the sealing block 3321 can be rotated to make the sealing block 3321 and the port 331 misaligned and separated. The operator can then perform the corresponding operation through the port 331 to release the sealing block 3321. Under the action of the torsion spring 3324, the sealing block 3321 can automatically reset.
[0037] In addition, a positioning rod 333 is provided on the fireproof cover 33, and a positioning sleeve matching the positioning rod 333 is provided on the electrical component 2. The positioning rod 333 is inserted into the positioning sleeve. In use, the operator holds the fireproof cover 33, aligns the positioning rod 333 with the positioning sleeve, and inserts it. When the positioning rod 333 is inserted into the positioning sleeve, it can position the plug 31 and insert the plug 31 into the slot 21. At this time, the first locking mechanism and the second locking mechanism lock the plug 31 and the slot 21 together, preventing the plug 31 from falling off the slot 21 due to the wire harness on the plug 31 being pulled.
[0038] The working principle of this device is as follows: During use, pinch the fireproof cover 33 to align the positioning rod 333 with the positioning sleeve and insert it. When the positioning rod 333 is inserted into the positioning sleeve, it positions the plug 31 and inserts it into the slot 21. Simultaneously, the locking plate 322 is also inserted into one side of the locking seat 221. The locking block 225, compressed by the locking plate 322, enters the locking seat 221. At this time, the guide spring 223 and the guide rod 222 are also compressed. When the locking block 225 aligns with the locking hole on the locking plate 322, the guide spring 223 causes the locking block 225 to pop out of the locking seat 221 and engage with the locking plate 322, thus locking the plug 31 in the slot 21 and preventing damage during insertion. When the wire harness on the head 31 is pulled, the plug 31 falls off the slot 21. At the same time, the fireproof cover 33 covers the connection between the plug 31 and the slot 21, which can provide fireproof and heat insulation for the connection between the plug 31 and the slot 21. When the plug 31 is inserted into the slot 21, the pressure block 325 will also enter the socket 226. At this time, the auxiliary spring 227 will be compressed. When it is necessary to separate the plug 31 from the slot 21, rotate the sealing block 3321 and make the sealing block 3321 and the through port 331 misaligned and separated. Press the locking block 225 through the through port 331 and make the locking block 225 enter the locking seat 221. At this time, under the action of the auxiliary spring 227, the plug 31 will pop out from the slot 21, which facilitates the separation of the plug 31 and the slot 21 and the operation is relatively convenient.
[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
