Among them, fasteners need to be provided on the electric control panel to fixedly connect wires. The upper end of the fastener should lock and connect the wire, and the lower end is connected to the electric control panel, so that the electric control panel can be conducted with the connecting wire through the fastener for current transmission.

[0003] Since the electric control panel is often used in the high-voltage field, the fastener needs to meet the requirement of carrying a large current. In the prior art, the pin of the fastener is welded to the electric control panel by soldering. When a large current passes through, high temperature will be generated, causing the solder joint to melt and fall off, which poses a safety hazard. In addition, in the prior art, only the connection method of locking to the electric control panel through an opening is used, and the formed hollow structure has a small cross-sectional area and cannot meet the requirement of passing a large current either.

[0009] Preferably, the locking conductor column and the riveting bottom column are cylindrical.

[0010] Preferably, the locking conductor column and the riveting bottom column are copper columns.

[0011] Preferably, the diameter length of the riveting bottom column is less than that of the locking conductor column.

[0012] Preferably, a relief area for the screw tail is formed at the bottom of the locking hole, and the relief area is in the shape of a cone with a gradually decreasing diameter.

[0025] Combined with Figures 1 to 3 As shown, an embodiment of the present utility model provides a riveting fastener with a locking hole, which includes a locking conductor post 1 and a riveting bottom post 2.

[0026] A locking hole 10 is provided at the center of the top end of the locking conductor post 1, and the locking hole 10 is a threaded blind hole structure for locking a wiring compression screw.

[0027] The riveting bottom post 2 extends from the bottom end of the locking conductor post 1. The riveting bottom post 2 is a solid structure and is used for riveting and fixing on the conductor layer 31 of the electric control panel 30, so that the connecting wire fixed by the wiring compression screw in the locking hole 10 can be electrically connected to the conductor layer 31 of the electric control panel 30 through the locking conductor post 1.

[0028] For the above-mentioned riveting fastener with a locking hole, a locking hole 10 is provided above to lock the wiring compression screw, which can make the connecting wire be fixed between the wiring compression screw and the locking hole 10, realizing reliable connection of the wire, not easily falling off, and the connection method of screw locking is simple and rapid, facilitating wiring and wire replacement and disassembly, which is beneficial to improving the operation efficiency; while a riveting bottom post 2 is provided below to be riveted and fixed to the conductor layer 31 of the electric control panel 30, which not only avoids problems such as de-welding, false welding, and flux contamination that may occur when using the welding fixing method in the high-voltage field in the prior art, but also can form a stable connection between the riveting fastener and the electric control panel 30. There is no need to open holes on the riveting bottom post 2, and the solid structure is maintained to meet the over-current capacity requirements in the high-voltage field. Therefore, by using the above-mentioned riveting fastener, a stable and reliable connection is ensured when the circuit passes through a large current, and the safety of the electric control panel is guaranteed.

[0029] In this embodiment, to adapt to the wiring compression screw and the opening of the electric control panel, the locking conductor post 1 and the riveting bottom post 2 are cylindrical, and the central axes of the locking conductor post 1 and the riveting bottom post 2 are on the same straight line.

[0030] Exemplarily, the locking conductor post 1 and the riveting bottom post 2 are copper columns. The formed copper riveting fastener has a wide current application range and can meet the over-current requirements of many high-power electrical components.

[0031] To make the locking conductor post 1 stand upright above the electrical control panel 30, and the riveting bottom post 2 is tension-fixed in the riveting hole 310 of the electrical control panel 30. The diameter length of the riveting bottom post 2 is smaller than that of the locking conductor post 1, forming an overall stepped structure.

[0032] According to the actual production requirements, the locking holes 10 can be made in different sizes to fit various specifications of screws. Exemplarily, the locking holes 10 can be threaded holes adapted to screws such as M3 screws, M4 screws, and M5 screws. The respective structural dimensions of the riveting fastener including the locking holes 10 can be adjusted according to different requirements. Taking the M3 screw as an example, the following provides a preferred example of the dimensions of the riveting fastener:

[0033] The axial length L1 of the locking conductor post 1 is 9.8 - 10.2 mm, and the axial length L2 of the riveting bottom post 2 is 5.85 - 6.15 mm;

[0034] The diameter length D1 of the locking conductor post 1 is 4.9 - 5.1 mm, the diameter length D2 of the locking hole 10 is 3 mm, and the diameter length D3 of the riveting bottom post 2 is 2.85 - 3.15 mm;

[0035] The depth H1 of the locking hole 10 is 6 mm.

[0036] Furthermore, to accommodate different tail structures of screws, such as flat-tail screws, self-tapping pointed screws, and cut-tail screws, and adapt to different application scenarios, a relief area 101 for the screw tail is formed at the bottom of the locking hole 10, and the relief area 101 is in the shape of a cone with a gradually decreasing diameter.

[0037] The riveting bottom post 2 is tension-fixed in the riveting hole 310 of the electrical control panel 30, and the outer side surface of the riveting bottom post 2 abuts against the inner wall of the riveting hole 310. To increase the friction between the outer side surface of the riveting bottom post 2 and the inner wall of the riveting hole 310 and make the riveting structure more stable, in this embodiment, the surface of the riveting bottom post 2 is formed with knurling 21.

[0038] The embodiment of the present invention also provides an electrical control panel, which includes a conductor layer 31 and the riveting fastener with the locking holes 10 as described above. A plurality of riveting holes 310 are formed on the conductor layer 31, and the riveting bottom post 2 of the riveting fastener is riveted and fixed in the riveting holes 310 of the conductor layer 31.
