Central power supply member and method of assembling it

摘要

An object of the present invention is to prevent a power supply terminal from being dragged and rotated in the case of connecting a power-supply side terminal to the power supply terminal by tightening a bolt.

<Paragraphs id="pa02" num="0002" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">In a central power supply member S for supplying power to windings of a stator of a motor, a plurality of ring-shaped busbars 10 each including a power supply terminal 20 and connecting terminals 30 to the windings are laminated and accommodated in a holder 50 made of synthetic resin while being insulated from each other, and power-supply side terminals 91 drawn out from a power supply are individually placed on the power supply terminals 20 of the respective busbars 10 and connected by tightening bolts 95. The holder 50 is formed with terminal blocks 55 on which the power supply terminals 20 can be placed and in which nuts 65 to be threadably engaged with the bolts 95 are mounted with the rotation thereof prevented, and insertion grooves 88 as rotation preventing portions into which bulging portions 27 formed on the lateral edges of vertical plates 22 of the power supply terminals 20 are inserted are formed in the rear surfaces of the terminal blocks 55.
