[0002] Junction boxes, as an indispensable key component in electrical systems, bear the core function of connecting wires and cables to protective circuit connection points. They are an important link in ensuring the stable operation of electrical systems and electrical safety. They can orderly gather and reliably connect scattered wires and cables, placing the circuit connection points in a closed and safe environment. This effectively isolates external interference factors such as dust, moisture, and impurities, avoiding safety hazards such as short circuits and leakage caused by exposed connection points. At the same time, they can also reduce damage to connection points caused by external mechanical collisions, significantly improving the stability and safety of circuit operation.

[0003] Currently, traditional junction boxes connect high-voltage and low-voltage circuits or different circuits, which can easily cause electromagnetic interference or even short circuits. In addition, the covers on the junction boxes are mostly split or top-removable, which is cumbersome to install and remove. They also have weak dust and water resistance. Furthermore, the covers need to be completely removed during maintenance, which makes them easy to lose and exposes too much operating space, increasing the risk of accidental contact.

[0004] A multi-functional junction box with multiple opening and closing methods is proposed to solve the problems mentioned above. Utility Model Content

The specific details are as follows:

[0019] 1. The junction box can be assembled using two side plates, a base plate, a heat sink, and a mounting plate. The entire assembly can be joined with screws. The partition can isolate different spaces within the junction box. Both side plates and the mounting plate have wire holes, and the partition also has several wiring holes for easy isolation of different circuits. During use, the cover plate is hinged between the two side plates. When closed, the cover plate fits snugly against the side plates, and a silicone sealing strip is provided on the cover plate to improve sealing performance.

[0020] 2. Different circuits are isolated on one side of the partition. When sealing the circuit, the sealing plate can be placed on two support frames. The sealing plate has a U-shaped side profile. After the sealing plate is placed on the support frame, the mounting block abuts against the fixing frame. At this time, one side of the partition is not completely sealed. One side of the sealing plate abuts against the two positioning strips. When the cover is closed, the limiting strip on the cover is inserted into the inclined groove. After the cover is completely closed, the slope at the bottom of the limiting strip abuts against the inclined groove. At this time, the sealing plate can be pushed backward, which can compress the telescopic spring and telescopic rod. The sealing plate abuts against the fixing frame, so that the second protrusion on the sealing plate abuts against the second strip groove. At this time, the space on one side of the partition is sealed. When the cover is opened later, the sealing plate can be opened automatically under the action of the telescopic spring. During subsequent maintenance, only the sealing plate needs to be picked up. The sealing plate can seal the space on one side of the partition, and the sealing plate can be easily removed after the cover is opened, which improves practicality. Attached Figure Description

[0032] Working principle: Before using this multi-functional junction box with multiple opening and closing methods, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 7As shown, the junction box can be assembled using two side plates 1, a base plate 103, a heat sink 105, and a fixing plate 104. The entire assembly can be joined using screws. A partition 102 separates different spaces within the junction box. Both side plates 1 and the fixing plate 104 have through holes, and the partition 102 has several wiring holes to facilitate the isolation of different circuits. During use, a cover plate 107 is hinged between the two side plates 1. When closed, the cover plate 107 fits snugly against the side plates 1. A silicone sealing strip is provided on the cover plate 107 to improve sealing performance. The cover plate 107 is made of metal. The cover plate 107 is made with a certain degree of elasticity. When the cover plate 107 is closed, the operator presses down on the cover plate 107, and the first protrusion on the cover plate 107 deforms and aligns with the first strip groove 108. The first protrusion can be stuck in the first strip groove 108, which can position the cover plate 107. When the cover plate 107 is opened later, the first protrusion on one side of the cover plate 107 can be pried open to open the cover plate 107. This can play an isolation role when facing different circuits or circuit distributions, avoid electromagnetic interference, and facilitate the disassembly of the cover plate 107 during maintenance and disassembly, thus improving the convenience of use.

[0033] One side of the partition 102 isolates different circuits. When sealing the circuit, the sealing plate 109 can be placed on two support frames 112. The sealing plate 109 has a U-shaped side profile. After the sealing plate 109 is placed on the support frame 112, the mounting block 119 abuts against the fixing frame 111. At this time, one side of the partition 102 is not completely sealed. One side of the sealing plate 109 abuts against the two positioning strips 113. When the cover 107 is closed, the limiting strip 114 on the cover 107 is inserted into the inclined groove 115. After the cover 107 is completely closed, the slope at the bottom of the limiting strip 114 abuts against the inclined groove 115. At this time, it is possible to... Pushing the sealing plate 109 backward allows the telescopic spring 118 and telescopic rod 117 to be compressed, and the sealing plate 109 abuts against the fixing frame 111, causing the second protrusion on the sealing plate 109 to abut against the second strip groove 110. At this time, the space on one side of the partition 102 is sealed. When the cover 107 is opened later, the sealing plate 109 can be opened automatically under the action of the telescopic spring 118. During subsequent maintenance, it is only necessary to pick up the sealing plate 109. Thus, the space on one side of the partition 102 can be sealed by the sealing plate 109, and the sealing plate 109 can be easily removed after the cover 107 is opened, improving practicality.
