The invention relates to a safety vehicle capacitor. It includes a box-shaped capacitor shell, lead-out electrode sheet, capacitor core accommodated inside capacitor shell and epoxy resin used to encapsulate the capacitor core. Said lead-out electrode sheet comprises of an inner connection end, an intermediate connection portion and outer connection, where the intermediate connection portion is in a shape of ‘n’ or ‘v’, one end of said intermediate connection portion being connecting to inner end of outer connection end horizontally, while the other end of intermediate connection portion being connected to up end of inner connection end with an angle; the inner wall of said capacitor shell is provided with inner mounting slot for the lead-out electrode sheet, and said inner connection end of said lead-out electrode sheet is inserted in to said inner mounting slot for fixing; the capacitor shell containing the inner mounting slot has a corresponding outer wall provided with a fixing pillar for the lead-out electrode sheet, and said outer connection end of the lead-out electrode sheet is fixed to the fixing pillar through a fixing element; said intermediate connection portion of the lead-out electrode sheet locates above the epoxy resin surface.
