Description

Technical Field

[0001] This utility model belongs to the field of electronic device technology, and in particular relates to a horizontal vehicle-mounted capacitor. 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 will cause vibration and impact on the radial direction of the capacitor cell, posing a significant safety hazard. Long-term use will cause the insulating paper of the aluminum electrolytic capacitor to vibrate and creep at both ends, 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 issue of capacitor mounting. Therefore, it is necessary to conduct research and development to provide a solution for fixing aluminum electrolytic capacitors in vehicles.

[0028] Reference Figures 1-3 As shown in the figure, as an embodiment of the present invention, a horizontal vehicle-mounted capacitor 300 is provided, including a capacitor body 200 and a fixing bracket 100 for mounting and fixing the capacitor body 200; the capacitor body 200 includes an aluminum shell 20, a core package encapsulated in the aluminum shell, a cover plate for encapsulating the core package in the aluminum shell, and lead-out terminals 21 disposed on the cover plate; the fixing bracket 100 includes a first fixing clamp 10 and a second fixing clamp 11, a horizontal reinforcing rib 12 connecting the first fixing clamp 10 and the second fixing clamp 11, and fixing pins 13 respectively extending from the first fixing clamp 10 and the second fixing clamp 11; wherein, the first fixing clamp 10 and the second fixing clamp 11 are used to fasten the two ends of the capacitor body respectively; the fixing pins 13 are disposed on the same side of the first fixing clamp 10 and the second fixing clamp 11 to mount and fix the fixing bracket 100 on a circuit board or an external device.

[0029] Reference Figures 1-2As shown, the distance between the first fixing clamp 10 and the second fixing clamp 11 is less than the length of the capacitor body. The centers of the first fixing clamp 10 and the second fixing clamp 11 are on the same axis and coincide with the center axis of the capacitor core. The first fixing clamp 10, the second fixing clamp 11, and the horizontal reinforcing rib 12 together form a capacitor receiving space to accommodate the capacitor body. After the capacitor body 200 is placed in the capacitor receiving space, the two ends of the capacitor body 200 are fastened by the first fixing clamp 10 and the second fixing clamp 11 respectively, thereby firmly fixing the capacitor body 200 to the capacitor fixing bracket 100. The capacitor is installed and fixed on the circuit board by the fixing pins 13 and capacitor lead-out terminals on the first fixing clamp 10 and the second fixing clamp 11.

[0030] Reference Figure 2 As shown, the first fixing clamp 10 includes a circular body 101 and an elastic portion 102 protruding outward from the circular body 101; wherein, the circular body 101 is connected to the transverse reinforcing rib 12 through the elastic portion 102; the extending direction of the transverse reinforcing rib 12 is perpendicular to the plane of the circular body 101. In some embodiments, the cross-section of the transverse reinforcing rib 12 is arc-shaped, and the inner surface of the transverse reinforcing rib 12 is a recessed groove; in some embodiments, the circular body 101 includes four arc-shaped spring pieces (not labeled), the four arc-shaped spring pieces are on the same circle, and the elastic portion 102 is provided between adjacent arc-shaped spring pieces; the four arc-shaped spring pieces are configured to match the surface of the capacitor to ensure that the inner side of the arc-shaped spring pieces is in close contact with the surface of the capacitor. In some embodiments, the four arc-shaped spring pieces have equal arc lengths and the same curvature; in some embodiments, the elastic portion 102 is approximately U-shaped, the opening at the bottom of the U-shape is equal in size to the slot of the transverse reinforcing rib 12, and the depth of the U-shape is greater than the arc depth of the transverse reinforcing rib 12. In some embodiments, the inner diameter of the circular body 101 is less than or equal to the outer diameter at both ends of the capacitor body 200. In some embodiments, the plane of the circular body 101 is perpendicular to the surface of the circuit board on which the capacitor is mounted.

[0031] Reference Figure 2 As shown, the structure of the second fixing clamp 11 is the same as that of the first fixing clamp 10. For details, please refer to the description of the first fixing clamp 10, which will not be repeated here. By setting the first fixing clamp 10 and the second fixing clamp 11 in this way, the two ends of the capacitor body can be fixed well, the capacitor body can be stably placed in the receiving space, and the overall fastening effect can be improved.

[0032] Reference Figure 3As shown, in some embodiments, an intermediate fixing clamp 14 is also provided between the first fixing clamp 10 and the second fixing clamp 11 to fasten the middle section of the capacitor body; the structure of the intermediate fixing clamp 14 is the same as that of the first and second fixing clamps 10 and 11, and will not be described again here.

[0033] Reference Figure 2 As shown, in some embodiments, there are four horizontal reinforcing ribs 12, which are respectively connected between the first fixing clamp 10 and the second fixing clamp 11. In some embodiments, the four horizontal reinforcing ribs 12 are parallel to each other and parallel to the surface of the circuit board on which the capacitor is mounted. This arrangement ensures the elasticity and strength of the capacitor mounting bracket.

[0034] The fixing pins 13 are respectively disposed on the two elastic portions of the first fixing clamp 10 and the second fixing clamp 11, and the two elastic portions are close to the circuit board on which the capacitor is mounted. In some embodiments, the fixing pins 13 are formed by a U-shaped bottom cutout of the elastic portion, that is, after the fixing pins 13 are bent, the U-shaped bottom of the elastic portion forms a complete arc without gaps. In some embodiments, the fixing pins 13 are inclined inward, and the plane on which the fixing pins 13 are located intersects with the two sides of the main body; it should be noted that the intersection here can be understood as the plane on which the fixing pins 13 are located being non-parallel to the two sides of the main body.

[0035] This invention uses two fixing clamps to fix the two ends of the capacitor body 200 respectively, thereby stably installing the capacitor body 200 on the fixing bracket 100. Furthermore, the capacitor is stably installed and fixed on the circuit board through the fixing pins 13 on the two fixing clamps and the lead-out terminals on the capacitor body. The structure is simple and robust.
