[0026] See also Figure 1-6 A power stud combination structure used on automotive domain controllers includes a metal base 1, a plastic base 2, and a stud 3. The metal base 1 is clamped onto the plastic base 2, and the cap end of the stud 3 is clamped between the metal base 1 and the plastic base 2. The stud 3 is made of SUS304 material with relatively low temperature rise and high strength, which can not only improve the strength of the stud 3, but also reduce the power-on temperature rise. When the power is 120A, the temperature rise is only 70°C. The plastic base 2 is made of PA6T, and the heat deformation temperature can reach 290°C. The stud 3 and the metal base 1 are crimped together. Compared with the ordinary welding process, the process is convenient to assemble, the efficiency is improved, and the cost is advantageous. In addition, the structure is simple and the production is convenient, which is conducive to improving production efficiency and can meet torque requirements.

[0027] The metal base 1 is provided with an inserting plate 4, and the plastic base 2 is provided with a slot that matches the inserting plate 4. The inserting plate 4 is provided with a soldering foot 5; the soldering foot 5 is soldered to the PCB through reflow soldering. The cooperation between the inserting plate 4 and the slot can limit the relative angle and position between the metal base 1 and the plastic base 2, making it easy to install and combine.

[0028] The plugboard 4 is divided into a main board 41 and a sub-board 42. The main board 41 and the sub-board 42 are arranged in pairs, and the main board 41 and the sub-board 42 form a rectangle; the welding feet of the metal base 1 are designed to be arranged in a square, which can ensure the torsion resistance of the entire structure.

[0032] A positioning column 11 is provided on the side of the plastic base 2 close to the metal base 1. The positioning column 11 cooperates with the cross keyway of the stud 3 to offset the torsion on the welding foot 5 of the metal base 1 during customer installation.

[0033] The plastic base 2 is provided with an anti-rotation structure, which is a corner plate 12 set at the corner of the plastic base 2, and a side plate 13 is provided between the corner plates 12 to prevent the wire end from rotating when the nut is tightened.

[0034] The anti-rotation structure also includes a side column 14 arranged on the edge of the plastic base 2. The side column 14 is connected to the side plate 13. The inner side of the side column 14 is arc-shaped and the side column 14 is inclined relative to the side plate 13; it plays an auxiliary role in preventing the line segment from rotating.

[0035] The plastic base 2 is provided with a limiting column 15 ; the limiting column 15 is assembled with the PCB, and three thin ribs are designed on each limiting column 15 to fit tightly with the board hole to reduce the influence of torsion on the soldering foot 5 .
