Description

Technical Field

[0001] This utility model belongs to the field of electronic device technology, and in particular relates to a vehicle-mounted anti-vibration capacitor. Background Technology

[0002] New energy vehicles generally use 450VDC-500VDC high-voltage aluminum electrolytic capacitors with a lifespan of 105℃ and 3000-5000 hours, requiring high explosion-proof performance. Currently, aluminum electrolytic capacitors in new energy vehicles are mainly secured by the upper and lower covers of the on-board charger (OBC) box. During long-term use, loosely secured aluminum electrolytic capacitors will resonate with the vehicle's movement, causing radial vibration impact on the capacitor cells, posing a significant safety hazard. Prolonged use can also cause the insulating paper at both ends to vibrate and creep, eventually leading to short circuits and explosions.

[0003] However, the aluminum electrolytic capacitors currently used in new energy vehicles do not adequately address the issues of explosion-proof and shock-resistant properties. Therefore, it is necessary to conduct research and development to provide a solution to address the explosion-proof and shock-resistant problems of automotive capacitors.

[0029] Reference Figures 1-4 As shown in the figure, as an embodiment of the present invention, a vehicle-mounted anti-vibration capacitor 300 is provided, including a capacitor body 200 and a capacitor anti-vibration fixing bracket 100; the capacitor body 200 includes an aluminum shell 20, a core package (not shown) encapsulated in the aluminum shell 20, a cover plate (not shown) for encapsulating the core package in the aluminum shell, and lead-out terminals 21 disposed on the cover plate; the anti-vibration fixing bracket 100 includes at least two annular sleeves 10, multiple reinforcing ribs 11 connecting the annular sleeves 10, and multiple fixing feet 12 for fixing the capacitor; wherein, the two annular sleeves 10 are respectively disposed at both ends of the anti-vibration fixing bracket 100, and the center line connecting the two annular sleeves 10 coincides with the central axis of the capacitor body 200; the two annular sleeves 10 and the multiple reinforcing ribs 11 connecting the two annular sleeves 10 form a cylindrical space for placing the capacitor body 200.

[0030] Reference Figure 2 As shown, the annular sleeve 10 is circular, and its inner diameter matches the outer diameter of the capacitor body 200, so that the surface of the capacitor body 200 is in full contact with the inner surface of the annular sleeve 10. In some embodiments, the width of the annular sleeve 10 is less than one-third of the height of the capacitor body. In some embodiments, the height of the shockproof fixing bracket 100 matches the height of the capacitor body 200, ensuring that more than two-thirds of the volume of the capacitor body is placed inside the shockproof fixing bracket 100; in some embodiments, the annular sleeve 10 of the shockproof fixing bracket 100 and the reinforcing rib 11 are integrally formed; the inner surface of the reinforcing rib 11 is configured as an arc-shaped surface that matches the surface of the capacitor body 200.

[0031] Reference Figure 3As shown in the embodiment of this utility model, there are three annular sleeves 10, one of which is disposed in the middle of the shockproof fixing bracket 100, and the other two annular sleeves 10 are disposed at both ends of the shockproof fixing bracket 100. In some embodiments, the interval between any two adjacent annular sleeves 10 is equal.

[0032] Reference Figures 1-3 As shown, the plurality of reinforcing ribs 11 are uniformly disposed on the surface of the shock-absorbing fixing bracket 100; specifically, the extending direction of the reinforcing ribs 11 is parallel to the central axis of the shock-absorbing fixing bracket 100; it should be noted that, in some embodiments, when the number of reinforcing ribs 11 is even, the plurality of reinforcing ribs 11 are symmetrically disposed on the surface of the shock-absorbing fixing bracket 100. When the number of reinforcing ribs 11 is odd, the plurality of reinforcing ribs 11 are equidistantly disposed on the surface of the shock-absorbing fixing bracket 100. In some embodiments, the plurality of reinforcing ribs 11 are disposed parallel to each other.

[0033] Reference Figure 4 , Figure 5 As shown, the reinforcing rib 11 is provided with a T-slot 110, and the fixing foot 12 is installed within the T-slot 110. In some embodiments, the fixing foot 12 is plate-shaped, its size adapted to the T-slot 110, and movably installed within the T-slot 110. The fixing foot 12 is movably installed within the T-slot; this design allows for more flexible fixing and enhances the strength of the fixing foot 12, resulting in a more secure fixation. (Refer to...) Figure 1 , Figure 2 As shown, the extending direction of the fixed foot 12 is the same as the extending direction of the lead-out terminal 21.

[0034] In some embodiments, refer to Figure 2 , Figure 5 As shown, the T-slot 110 has a flat opening at one end and a baffle 111 at the other end. The fixing foot 12 includes a sheet-like body 120 and a prong 121 extending from one end of the sheet-like body. The width of the sheet-like body 120 is greater than the width of the prong 121. The sheet-like body 120 is completely placed within the T-slot 110, and the prong 121 protrudes from the T-slot 110. The baffle 111 within the T-slot blocks the sheet-like body 120, preventing the fixing foot 12 from slipping out of the T-slot 110. In some embodiments, the width of the sheet-like body 120 is less than or equal to the width of the T-slot 110. Specifically, refer to... Figure 2 , Figure 4 , Figure 5As shown, during installation, the pin end of the fixing foot 12 is inserted into one end of the flat opening of the T-slot 110. The stop piece 111 at the other end of the T-slot 110 blocks the sheet-like body 120 of the fixing foot 12. The pin 121 of the fixing foot 12 extends out of the T-slot 110, thereby movably installing the fixing foot 12 in the T-slot 110.

[0035] In some embodiments, the number of reinforcing ribs 11 is at least two, the annular sleeve 10 is circular, and the diameter of the annular sleeve 10 coincides with the line connecting the two reinforcing ribs 11. In this embodiment of the present invention, the number of reinforcing ribs 11 is three, and the line connecting the three reinforcing ribs 11 forms a regular triangular prism. This arrangement can enhance the stability of the shockproof fixing bracket 100, further making the installation of the capacitor more stable and reliable, and improving its shock resistance.

[0036] This utility model provides a shockproof fixing bracket 100, in which the capacitor body 200 is placed and fixed to the circuit board by the fixing feet 12 and lead terminals that are movably installed on the shockproof fixing bracket. This achieves capacitor shock reduction while flexibly and reliably fixing the capacitor to the circuit board or other external devices.
