[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 3 As shown, a high-efficiency wiring power junction box includes a box body 1 and a box cover 2. Positioning columns 9 are provided at the four corners inside the box body 1. Threaded holes for installing screws are provided in the middle of the positioning columns 9. Through holes corresponding to the positions of the threaded holes are provided at the four corners of the box cover 2. Terminals 3 are installed inside the box body 1. Heat dissipation holes are provided on the bottom and sides. An inlet pipe 4 is provided at one end of the box body 1, and a plurality of outlet pipes 5 are provided at the other end. Fixed seats 6 are symmetrically fixed on both sides of the box body 1, and a supporting plate 7 for placing the terminal 3 is fixed between the two fixing seats 6. A plurality of heat sinks 10 are provided at the bottom of the supporting plate 7.

[0024] The box body 1 and the box cover 2 are connected and fixed by passing the screws through the through holes and installing them on the positioning columns 9. The supporting plate 7 and the heat sink 10 are made of metal plates with good thermal conductivity. The heat dissipation performance can be improved through the design of the heat dissipation holes and the heat sink 10, thereby avoiding damage to the terminal blocks caused by excessive temperature at the terminal blocks.

[0025] like Figures 3 to 6 As shown, ear plates 8 are symmetrically fixed to both ends of the connecting terminal 3, a positioning groove matched with the ear plate 8 is opened on the top surface of the fixing seat 6, and a positioning component for fixing the ear plate 8 is arranged inside the fixing seat 6.

[0026] The positioning assembly includes a positioning plate 11 that is installed on the upper part of the fixed seat 6. A through hole is opened at one end of the positioning plate 11 located inside the fixed seat 6, and a positioning rod 12 is arranged in the through hole. A horizontal plate 13 is fixedly connected to the bottom of the positioning rod 12. A vertical rod 14 that can slide up and down is arranged inside the fixed seat 6. A pressure block 15 is fixedly connected to the top of the vertical rod 14, and the bottom is connected to the horizontal plate 13. A slot that is compatible with the positioning plate 11 is opened on the upper part of the fixed seat 6, and the slot runs through the positioning slot. A cylindrical cavity one and a cavity two are arranged inside the fixed seat 6. The lower parts of the cavity one and the cavity two are connected by a through slot. The two ends of the horizontal plate 13 are respectively located inside the cavity one and the cavity two. A fixing ring 16 is arranged inside the cavity two. A spring 17 that is sleeved on the outside of the vertical rod 14 is arranged above the fixing ring 16. The outside of the vertical rod 14 is fixedly connected to a limiting ring 18 at the inner upper part of the cavity two. A handle 19 is fixedly connected to the end of the positioning plate 11.

[0027] After connecting the wire to the terminal block 3, place the terminal block 3 on the supporting plate 7, and make the ear plates 8 at both ends of the terminal block 3 snap into the positioning groove, apply downward pressure to the pressure block 15, so that the vertical rod 14 drives the horizontal plate 13 and the positioning rod 12 to move downward, and at the same time, the limiting ring 18 squeezes the spring 17. At this time, the positioning plate 11 can be inserted into the slot, and the pressure block 15 is released. Under the action of the spring 17, the positioning rod 12 is inserted into the through hole at the end of the positioning plate 11 to prevent the positioning plate 11 from falling off the slot, and then the positioning plate 11 is used to limit and fix the ear plate 8, that is, the installation and fixation of the terminal block 3 is achieved.

[0028] In specific use, press the pressure block 15 downwards and use the handle 19 to pull the positioning plate 11 out of the slot.
