Description

Technical Field

[0001] The utility model relates to the technical field of electrical circuits, in particular to a high-voltage power supply assembly box. Background Art

[0002] The power junction box is a kind of electrical auxiliary material. Its main purpose is to be used as the connection between the wires and the wire tube, cable tray, etc. in the electrical circuit. When the line is long or needs to turn, the junction box can be used as a transition point to connect the wire tube to the junction box so that the wires are connected inside the junction box, which plays a role in protecting and connecting the wires. In addition, the junction box also helps to enhance the safety performance of the component, seal the current output part of the component (the lead part), and make the component more convenient and reliable to use;

[0003] A Chinese patent with publication number CN205793817U was searched and found to disclose a high voltage power supply assembly box.

[0004] In the above technical solution: an insulating and sealed soft layer is attached to the inner wall surface of the assembly box, which improves the sealing and insulation performance of the assembly box as a whole; the insulating and sealed soft layer has a stacked structure at the wiring hole position, thereby strengthening the insulation sealing at the wiring hole; the insulating and sealed soft layer also overflows to the wiring hole at the wiring hole position to cover the hole wall, thereby avoiding friction and protecting the cable;

[0005] However, in the above scheme, the technology requires opening the entire box body each time wiring is done. The electrical components inside, such as the voltage stabilizer, are already assembled. If the entire box body is opened rashly, problems may easily occur with the installed electrical components. This technology wraps a soft layer inside the wiring hole to fix the external power cord to avoid friction, but it will aggravate the bending of the external power cord outside its fixing point, causing the external power cord to be overstretched and causing the outer skin to be damaged.

[0006] To this end, we propose a high voltage power supply assembly box. Utility Model Content
