Device for assembling capacitors for an electronic converter

摘要

The device (100) for assembling capacitors (200) is intended for an electronic converter with a plurality of arms provided with transistors. The device comprises a bus bar (11) with positive polarity and a bus bar (12) with negative polarity. The bus bar with positive polarity and the bus bar with negative polarity are superposed one on top of the other without electrical contact. Preferably, the bus bar with positive polarity comprises a width (L1) smaller than the width (L2) of the bus bar with negative polarity. The device further comprises a support part (13) for insulating and indexing, arranged between the bus bar with positive polarity and the bus bar with negative polarity. The support part for insulating and indexing is typically formed from PBT plastic material reinforced with fiberglass.
