Abstract

A terminal block of a rotating electric machine includes a terminal block main body, a high-current electrical wire connecting section to which a high-current electrical wire of the rotating electric machine is connected, multiple neutral wire connecting sections to which neutral wires of the rotating electric machine are connected, and a bus bar that connects the neutral wire connecting sections to each other.

First claim

The invention claimed is:

1. A terminal block connecting with a plurality of neutral wires and a plurality of high-current electrical wires extended from coils of a rotating electric machine, the terminal block comprising:
a terminal block main body;
a plurality of high-current electrical wire connecting sections which are provided in the terminal block main body and to which a terminal of the plurality of high-current electrical wires extended from the coils of the rotating electric machine is respectively connected;
a plurality of neutral wire connecting sections which are provided in the terminal block main body and to which a terminal of the plurality of neutral wires is respectively connected; and
a bus bar which is fixed to the terminal block main body and connects the plurality of neutral wire connecting sections to each other, wherein
the terminal block main body has a partition wall provided between a high-current electrical wire connecting section and the bus bar, and
the partition wall is made of a material having an electrical insulating property.

2. The terminal block of the rotating electric machine according to claim 1 , wherein
the terminal block main body has a fixing portion for fixing the bus bar, and
in the terminal block main body, a slit is formed for inserting the bus bar.

3. The terminal block according to claim 2 , wherein
the terminal block main body has a lid member to close the slit.

4. The terminal block according to claim 1 , wherein
the terminal block main body has a fixing tab for fixing the bus bar.
