Description

Technical Field

[0001] This utility model relates to the field of power junction boxes, and in particular to a leakage-proof power junction box. Background Technology

[0002] A leakage current protection junction box is an electrical protection device used for connecting, branching, or transferring power lines. Its core function is to prevent the risk of leakage current caused by factors such as insulation damage and humid environment, thereby ensuring electrical safety.

[0003] Traditional technologies for power cord organization typically use early or basic methods such as plastic conduits, clip-on mounting brackets, and ordinary cable management racks, or even no organization structure at all. While these technologies can initially organize the lines, they are insufficient in terms of flexibility and maintenance efficiency, making them difficult to adapt to modern power usage scenarios. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a leakage-proof power supply junction box, which aims to improve the problem of uneven wiring caused by incomplete wiring technology in traditional technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A leakage current protection junction box includes a base plate with bolt holes inside. A first hexagonal bolt is installed inside the bolt holes. A junction box housing is fixedly connected to the upper surface of the base plate. A threaded rod is installed inside the junction box housing. A nut is threaded onto the outside of the threaded rod. A second hexagonal bolt is installed inside the nut. A nut is threaded onto the outside of the threaded rod. A fixing mechanism is fixedly connected inside the junction box housing.

[0007] Preferably, the fixing mechanism includes a fixing plate, which is externally fixedly connected to the inside of the junction box housing. A convex guide plate is externally fixedly connected to the fixing plate, and a first spring and a second spring are installed between the fixing plate and the convex guide plate.

[0008] Preferably, one end of the first spring is fixedly connected to a U-shaped guide plate.

[0009] Preferably, a conductive bar is fixedly connected inside the junction box housing, and a support block is fixedly connected to both ends of the conductive bar. A first groove is formed inside the support block, and a third spring is installed inside the first groove.

[0010] Preferably, an I-shaped support plate is fixedly connected to the outside of the support block, and a limit plate is fixedly connected to the upper surface of the I-shaped support plate.

[0011] Preferably, a first push rod is slidably connected to the upper surface of the I-shaped support plate.

[0012] Preferably, a cover plate is fixedly connected to the upper surface of the support block, and a second groove is formed inside the cover plate.

[0013] Preferably, a second push rod is installed inside the second groove, and a fourth spring is installed between the second push rod and the second groove.

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

[0015] 1. In this utility model, by placing the power cord into the convex guide plate, the power cord squeezes the convex guide plate. At this time, the first spring and the second spring generate a reaction force to squeeze the convex guide plate, clamping the power cord, thereby tidying up the power cord and making the power cord in the junction box shell neatly arranged.

[0016] 2. In this utility model, the second push rod is pressed down into the first groove. When it descends to a certain position, the fourth spring uses a reaction force to lock the second push rod into the first groove. When disassembly is required, the first push rod is pushed, and at the same time, the third spring uses a reaction force to lift the cover plate, thus achieving the effect of quick installation and disassembly of the cover plate.
