Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electronic device technology, and in particular relates to a vertical vehicle-mounted capacitor fixing device. Background Technology
[0002] With the development and popularization of new energy vehicles, automotive-grade electronic components will be used in a standardized manner. For capacitor-type electronic components, mandatory certification will be implemented, and manufacturers must meet the requirements to be allowed entry. Regarding the single measure of capacitor vibration safety certification, most automakers currently use adhesive bonding for reinforcement and the entire unit is secured by the upper and lower covers of the onboard charger (OBC).
[0003] During long-term use, aluminum electrolytic capacitors that are not securely fixed are in a state of resonance with the movement of the car body, which causes radial vibration impact on the capacitor cells, posing a significant safety hazard. Long-term use will cause the ends of the insulating electrolytic paper to vibrate and creep, eventually leading to short circuit and explosion failure.
[0004] However, the aluminum electrolytic capacitors currently used in new energy vehicles do not adequately address the capacitor fixing issue. Therefore, it is necessary to conduct research and development to provide a solution to the problem of fixing vehicle capacitors.
[0005] The above background information is provided only to aid in understanding the inventive concept and technical solution of this utility model. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application.

The center of the bottom fixing clamp 10 is on the same axis and coincides with the center axis of the capacitor core. The bottom fixing clamp 10, the top fixing clamp 20, and the support column 30 together form a capacitor receiving space to accommodate the capacitor. After the capacitor 200 is placed in the capacitor receiving space, the two ends of the capacitor are fastened by the bottom fixing clamp 10 and the top fixing clamp 20 respectively, thereby firmly fixing the capacitor to the capacitor fixing device 100. The capacitor 200 is installed and fixed on the circuit board by the fixing pin 40 on the top fixing clamp 20 and the capacitor lead-out terminal.
[0031] Reference Figures 2-4 As shown, the bottom fixing clamp 10 includes a circular body 11 and an elastic portion 12 protruding outward from the circular body 11; wherein, the circular body 11 is connected to the support column 30 through the elastic portion 12; the extension direction of the support column 30 is perpendicular to the plane of the circular body 11. In some embodiments, the cross-section of the support column 30 is arc-shaped, and the inner surface of the support column 30 is a recessed groove; in some embodiments, the circular body 11 includes four arc-shaped spring pieces 110, the four arc-shaped spring pieces 110 are on the same circle, and the elastic portion 12 is provided between adjacent arc-shaped spring pieces 110; the four arc-shaped spring pieces 110 are configured to match the surface of the capacitor to ensure that the inner side of the arc-shaped spring piece 110 is in close contact with the surface of the capacitor. In some embodiments, the four arc-shaped spring pieces 110 have equal arc lengths and the same curvature; in some embodiments, the elastic part 12 is approximately U-shaped, the opening at the bottom of the U-shape is equal in size to the slot of the support column 30, and the depth of the U-shape is greater than the arc depth of the support column 30. In some embodiments, the inner diameter of the circular body 11 is less than or equal to the outer diameter of both ends of the capacitor.
[0032] Reference Figures 2-3As shown, the structure of the top fixing clamp 20 is the same as that of the bottom fixing clamp 10. For details, please refer to the description of the bottom fixing clamp 10, which will not be repeated here. By setting the top fixing clamp 20 and the bottom fixing clamp 10 in this way, the two ends of the capacitor body can be well fixed, the capacitor body can be stably placed in the receiving space, and the overall fastening effect can be improved.
[0033] Reference Figure 5 As shown, in some embodiments, an intermediate fixing clamp 13 is also provided between the bottom fixing clamp 10 and the top fixing clamp 20 to fasten the middle section of the capacitor; the structure of the intermediate fixing clamp 13 is the same as that of the bottom fixing clamp 10, and will not be described again here.
[0034] In some embodiments, there are four support columns 30, which are respectively connected between the top fixing clamp 20 and the bottom fixing clamp 10. In some embodiments, the four support columns 30 are arranged in pairs facing each other, which ensures the elasticity and strength of the capacitor fixing device.
[0035] Reference Figure 3 , Figure 4 As shown, the fixing pin 40 extends along the support column 30 and is on the same straight line as the support column 30; there are at least two fixing pins 40, both of which are disposed on the top fixing clamp 20, and the extending direction of the fixing pin 40 is perpendicular to the plane of the circular body of the top fixing clamp 20, or the angle between the extending direction of the fixing pin 40 and the plane of the circular body of the top fixing clamp 20 is greater than zero degrees. In some embodiments, the extending direction of the fixing pin 40 is the same as the extending direction of the lead terminals of the capacitor body. In some embodiments, the two fixing pins 40 are arranged diagonally, and the line connecting the two fixing pins 40 intersects the line connecting the two lead terminals of the capacitor. In this embodiment, there are four fixing pins 40 in total, and the four fixing pins 40 are respectively disposed on the four elastic parts of the fixing clamp, and the four fixing pins 40 are connected in sequence to form a square. By setting the pins in this way, the capacitor body can be stably fixed on the external circuit board, and all the fixing pins 40 are set on the same fixing clamp. When the fixing pin 40 is damaged, only one fixing clamp will be affected, and it will not affect both fixing clamps.
[0036] This invention uses two fixing clamps to fix the two ends of the capacitor body respectively, thereby stably installing the capacitor body on the fixing device. Furthermore, the capacitor can be stably installed and fixed on the circuit board through the fixing pin 40 on one of the fixing clamps and the lead-out terminals on the capacitor body. The structure is simple and robust.
