[0002] In the field of metallized film capacitors for AC motors, the existing AC motor film capacitors with bases can be easily installed, but because the base is made of plastic, it cannot play a grounding role, posing safety hazards and insufficient safety performance. Although ordinary bolt structure capacitors can solve the grounding problem, their installation process is complicated and require separate nuts and washers for installation. Especially for capacitors inside the entire chassis without a rear cover, the above problems are particularly prominent, and a new solution is urgently needed to improve safety and installation convenience. Summary of the invention

[0006] Preferably, the receiving portion is mainly composed of a base plate, a side frame and an upper support portion, and the three form a U-shape as a whole, wherein the base plate is detachable from the bottom end of the capacitor body, the side frame is pressed against the inner wall of the mounting hole, and the upper support portion is pressed against the top surface of the metal plate.

[0007] Preferably, the side frames and the upper support parts are each in two groups, wherein the two groups of side frames are symmetrically distributed along the central axis of the substrate and are respectively fixed on both sides of the substrate, and the two groups of upper support parts are respectively fixedly connected to the ends of the two groups of side frames.

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0022] Reference Figure 1-3As shown, a capacitor base includes a metal plate 1 and a capacitor body 2, the metal plate 1 is provided with a mounting hole for inserting the capacitor body 2, and also includes a safety base;

[0023] By setting up the mounting base, the capacitor body 2 is basically fixed on the metal plate 1. Compared with the existing plastic base, the mounting base can be effectively grounded, which greatly improves the safety and can meet the safety requirements of direct contact with the human body. Compared with the existing ordinary capacitor body 2 with a bolt structure, it is more convenient for the actual capacitor body 2 to be installed and used on the metal plate 1, without the need for complicated installation procedures and additional nuts and washers.

[0024] Specifically, refer to Figure 1-3 As shown, it is worth noting that the mounting base is mainly composed of a receiving portion and an elastic positioning portion, wherein the receiving portion is used for stable loading of the capacitor, and the elastic positioning portion is used for rapid implementation of the adaptive installation of the capacitor body 2 on the metal plate 1;

[0025] The receiving part is mainly composed of a substrate 3, a side frame 4 and an upper support part 5, which form a U-shape as a whole, wherein the substrate 3 can be detached from the bottom end of the capacitor body 2, the side frame 4 is pressed against the inner wall of the mounting hole, and the upper support part 5 is pressed against the top surface of the metal plate 1;

[0026] An escape slot is formed in the inner wall of the side frame 4, and the elastic positioning part is connected to the escape slot;

[0027] The side frames 4 and the upper support parts 5 are each in two groups, wherein the two groups of side frames 4 are symmetrically distributed along the central axis of the substrate 3 and are respectively fixed to the two sides of the substrate 3, and the two groups of upper support parts 5 are respectively fixedly connected to the ends of the two groups of side frames 4;

[0028] When installing the capacitor body 2, first, the bottom end of the capacitor body 2 must be accurately inserted into the mounting hole. When the bottom end of the capacitor body 2 is completely inserted into the mounting hole, the upper support portion 5 in the receiving portion will fit tightly against the upper surface of the metal plate, and the elastic positioning portion will firmly abut against the lower surface of the metal plate, thereby stabilizing the capacitor body 2 from both the upper and lower directions. In addition, the side frame 4 in the receiving portion will tightly abut against the inner wall of the mounting hole to provide lateral support and positioning. In this way, the side frame 4, the elastic positioning portion and the upper support portion 5 cooperate with each other to form a relatively stable support and positioning system for the capacitor body 2.

[0029] Further, refer to Figure 3 As shown, it is worth noting that the number of the elastic positioning parts is the same as that of the side frame 4, and the elastic connection positioning part is an inclined lower clamping part 6, one end of the lower clamping part 6 is against the bottom surface of the metal plate 1, and the other end is fixedly connected to the inner wall of the bottom end of the avoidance groove;

[0030] The substrate 3, the side frame 4, the upper support part 5 and the lower clamping part 6 are all stamped and formed by 0.4mm 65 manganese steel. 0.4mm 65 manganese steel is selected as the raw material to ensure that the quality and performance of the material meet the requirements;

[0031] By setting the elastic positioning part, when it is necessary to align the bottom end of the capacitor body 2 to penetrate the mounting hole, the lower clamping part 6 will pre-abut against the open inner wall of the mounting hole during this process. Based on the good elasticity of 65 manganese steel, the lower clamping part 6 can be squeezed and contracted toward the side frame 4 as the bottom end of the capacitor body 2 is continuously inserted, so that the lower clamping part 6 can smoothly penetrate the mounting hole with the capacitor body 2, reducing movement obstacles. After the lower clamping part 6 has completed passing through the mounting hole, the lower clamping part 6 can be reset and rebounded under its own elastic force to abut against the bottom surface of the metal plate 1, and cooperate with the upper support part 5 to have a good fixing effect on the capacitor body 2, so that the capacitor body 2 and the metal plate 1 are firmly integrated;

[0032] And because the substrate 3, side frame 4, upper support part 5 and lower clamping part 6 that mainly constitute the mounting base are all made of metal material 65 manganese steel, when the base is installed on the metal plate 1, the mounting base and the metal plate 1 form a good conductive path. During the operation of the AC motor, if abnormal conditions such as leakage occur, the current can be quickly conducted to the metal plate 1 through the mounting base, and then introduced into the earth, achieving effective grounding protection. This makes it possible to avoid the risk of electric shock even if the human body directly touches the mounting base, greatly improving the safety of use.

[0033] In addition, refer to Figure 2 and Figure 3 As shown, it is worth noting that two positioning parts 7 are symmetrically fixed on the outer edge of the top surface of the substrate 3, and a positioning notch matching with the positioning part 7 is opened at the bottom end of the capacitor body 2;

[0034] A connecting hole is formed through the center of the substrate 3, a self-tapping screw 8 is passed through the connecting hole, and the self-tapping screw 8 is threadedly connected to the bottom end of the capacitor body 2;

[0035] By setting the positioning part 7, the substrate 3 is connected to the capacitor body 2 by using the self-tapping screw 8. The two positioning parts 7 can be synchronously aligned and inserted into the positioning notch at the bottom of the capacitor body 2. In this way, the self-tapping screw 8 cooperates with the two positioning parts 7 to limit the six degrees of freedom, so that the substrate 3, the side frame 4 and the upper support part 5 are fixed on the capacitor body 2 as a whole.
