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. 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.

It does not necessarily belong to the prior art of this patent application.

[0013] In some embodiments, the extension direction of the fixed pin is the same as the extension direction of the lead-out terminals of the capacitor body.

[0014] In some embodiments, the number of fixed pins is at least two, and the two fixed pins are respectively disposed on two non-adjacent elastic protrusions.

[0015] In some embodiments, the two fixed pins are arranged diagonally, and the connection between the two fixed pins intersects with the connection between the two leads of the capacitor.
