Description

Insulating seal assembly of female row of electric capacity Technical Field The utility model relates to the technical field of capacitors, in particular to a capacitor busbar insulation sealing assembly. Background In the development primary stage of the electric vehicle, a general industrial-grade capacitor product is often adopted to meet the requirement of electric performance, and besides the electric performance, the electric vehicle has higher requirement on the tightness of the capacitor. At present, a structure of straight-in and straight-out is generally adopted by an output busbar of a busbar capacitor on an electric automobile driver, flexible sealing or shell splitting structure can be better made, sealing effect can be generally kept better by arranging sealing rings and the like at the penetrating-out positions of the structure, and higher sealing and insulating effects are difficult to keep when the busbar penetrates out of a shell after bending (special-shaped). Disclosure of utility model Aiming at the defects in the prior art, the utility model aims to provide a capacitor busbar insulation sealing assembly which can improve the tightness and insulativity of busbar terminals of a capacitor after encapsulation. The technical scheme includes that the capacitor busbar insulation sealing assembly comprises an encapsulation shell for encapsulating a capacitor body, wherein an outgoing hole for a busbar terminal of the capacitor body to penetrate is formed in the side face of the encapsulation shell, the capacitor busbar insulation sealing assembly further comprises a sealing block and an insulation sleeve, the sealing block is embedded into the inner side of the encapsulation shell corresponding to the outgoing hole, the sealing block is provided with a sealing port for the busbar terminal of the capacitor body to penetrate through, the insulation sleeve is of a U-shaped structure, and the insulation sleeve is sleeved on one end of the busbar terminal of the capacitor body penetrating out of the encapsulation shell. According to the technical scheme, the capacitor body is arranged in the packaging shell in a sealing mode, the reference hole formed in the packaging shell is used for leading out the busbar terminal, the sealing block is sleeved at the lead-out position of the busbar terminal and is embedded into the inner side of the lead-out hole to enable the lead-out position to keep good sealing performance, meanwhile, the insulating sleeve is sleeved at one end, penetrating out of the packaging shell, of the busbar terminal of the capacitor body to ensure the insulating effect of the adjacent busbar terminal, and the capacitor is safer and more stable in use. Preferably, the sealing block is in a frustum structure. Preferably, the sealing block and the insulating sleeve have elasticity. Preferably, a fixing table is arranged below the corresponding lead-out hole on the outer side surface of the packaging shell, and an assembly groove for embedding the end part of the busbar terminal is arranged at the upper end of the fixing table.
