Technical Field

[0001] This utility model relates to the field of capacitor base technology, specifically to a capacitor base. Background Technology

[0002] In the field of metallized film capacitors for AC motors, existing AC motor film capacitors with bases can be easily installed, but because the bases are made of plastic, they cannot serve as grounding devices, posing a safety hazard and resulting in insufficient safety performance. While capacitors with ordinary bolt structures can solve the grounding problem, their installation process is complicated and requires separate nuts and washers. This problem is particularly prominent for capacitors inside the chassis of some motors without a rear cover. Therefore, a new solution is urgently needed to improve safety and ease of installation. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a capacitor base, comprising a metal plate and a capacitor body, wherein the metal plate has a through mounting hole for inserting the capacitor body, and also includes a safety base.

[0005] The safety base mainly consists of a mounting part and an elastic positioning part, wherein the mounting part is used for the stable loading of the capacitor, and the elastic positioning part is used for the quick adaptation and installation of the capacitor body on the metal plate.

[0006] Preferably, the mounting portion mainly consists of a substrate, a side frame, and an upper support portion, which together form a U-shape. The substrate is detachable from the bottom of the capacitor body, the side frame abuts against the inner wall of the mounting hole, and the upper support portion abuts against the top surface of the metal plate.

[0007] Preferably, there are two sets of side frames and two sets of upper support parts. The two sets of side frames are symmetrically distributed along the central axis of the substrate and are fixed to both sides of the substrate respectively. The two sets of upper support parts are respectively fixedly connected to the ends of the two sets of side frames.

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figure 1-3As shown, a capacitor base includes a metal plate 1 and a capacitor body 2. The metal plate 1 has a through mounting hole for inserting the capacitor body 2, and also includes a safety base.

[0023] By setting a safety base, the capacitor body 2 can be fixed on the metal plate 1. Compared with the existing plastic base, the safety base can be effectively grounded, which greatly improves safety and meets the safety requirements for direct human contact. Compared with the existing ordinary capacitor body 2 with bolt structure, it is easier to install and use the actual capacitor body 2 on the metal plate 1 without complicated installation procedures and additional nuts and washers.

[0024] Specifically, refer to Figure 1-3 As shown, it is worth noting that the safety base is mainly composed of a mounting part and an elastic positioning part. The mounting part is used for the stable loading of the capacitor, and the elastic positioning part is used for the quick adaptation and installation of the capacitor body 2 on the metal plate 1.

[0025] The mounting part is mainly composed of a substrate 3, a side frame 4 and an upper support part 5. The three together form a U-shape. The substrate 3 can be detached from the bottom of the capacitor body 2, the side frame 4 abuts against the inner wall of the mounting hole, and the upper support part 5 abuts against the top surface of the metal plate 1.

[0026] An clearance slot is provided through the inner wall of the side frame 4, and the elastic positioning part is connected to the clearance slot.

[0027] There are two sets of side frames 4 and upper support parts 5. The two sets of side frames 4 are symmetrically distributed along the central axis of the substrate 3 and are fixed to both sides of the substrate 3 respectively. The two sets of upper support parts 5 are respectively fixedly connected to the ends of the two sets of side frames 4.

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

[0029] Furthermore, referring to Figure 3 As shown, it is worth noting that the number of elastic positioning parts is the same as that of side frame 4, and the elastic positioning part is an inclined lower clamping part 6. One end of the lower clamping part 6 abuts against the bottom surface of the metal plate 1, and the other end is fixedly connected to the bottom inner wall of the clearance groove.

[0030] The substrate 3, side frame 4, upper support part 5 and lower clamping part 6 are all made of 0.4mm 65 manganese steel by stamping. The selection of 0.4mm 65 manganese steel as raw material ensures that the quality and performance of the material meet the requirements.

[0031] With the setting of the elastic positioning part, when it is necessary to align the bottom end of the capacitor body 2 with the through hole, the lower clamping part 6 will pre-abut against the inner wall of the open mounting hole during this process. Based on the good elasticity of 65 manganese steel, the lower clamping part 6 can be squeezed and contracted towards 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 pass through the mounting hole with the capacitor body 2, reducing movement resistance. After the lower clamping part 6 has completed passing through the mounting hole, the lower clamping part 6 can reset and rebound 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] Furthermore, since the base plate 3, side frame 4, upper support part 5, and lower clamping part 6, which are the main components of the safety base, are all made of 65 manganese steel, when the base is installed on the metal plate 1, the safety base and the metal plate 1 form a good conductive path. During the operation of the AC motor, if there is an abnormal situation such as leakage, the current can be quickly conducted through the safety base to the metal plate 1 and then to the ground, achieving effective grounding protection. This means that even if a person comes into direct contact with the safety base, the risk of electric shock can be avoided, 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 that matches the positioning parts 7 is opened at the bottom end of the capacitor body 2.

[0034] A connecting hole is provided through the center of the substrate 3, and a self-tapping screw 8 is inserted into the connecting hole. 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 the self-tapping screw 8. The two positioning parts 7 can be aligned and inserted into the positioning notch at the bottom of the capacitor body 2 at the same time. In this way, the self-tapping screw 8 and the two positioning parts 7 work together to restrict 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.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
