Stack bus bar edge structure

Abstract

The invention relates to a marginal structure for a laminated busbar, comprising more than one layer of conductor layer(200) and an insulation layer(100) corresponding to the conductor layer(200), wherein the insulation layer(100) is arranged on both sides of the conductor layer(200); moreover, the invention also comprises a coating(300) inserted between the conductor layer(200) and the insulation layer(100), wherein the coating(300) is in sticking contact with the conductor layer(200) and the insulation layer(100) respectively, and has end surfaces(301) of the coating (300) paralleled with edges of the conductor layer(200) and the insulation layer(100); the marginal structure for a laminated busbar has the advantages of saving space due to the adoption of a mode of coating edges of conductors and further ensuring more reliable insulation.

Description

technical field [0001] The invention relates to a laminated busbar, in particular to an edge structure of the laminated busbar. Background technique [0002] At present, many electrical products begin to use laminated busbar technology to reduce parasitic inductance and obtain the best electrical performance. However, since the laminated busbar technology closely fits different conductors on both sides of the insulating layer, the distance between the conductors is very close, so the insulation between the conductors becomes a key factor in the design of the laminated busbar. [0003] For the insulation of the edge of the laminated busbar, there are two methods in the prior art: the first is to extend the edge of the insulating layer beyond the edge of the conductor layer, and the extension length is 1 / 2 of the maximum creepage distance between the conductors; the second is to Bond the extended insulating layer with an adhesive to seal it, and the extended length may be sho...

Problems solved by technology

However, bonding with adhesives cannot guarantee a complete seal. Once there is a gap and the extension length is not enough, creepage between conductors will occur, resulting in insulation failure and a potential safety hazard.
