Abstract

A bus bar assembly comprises a plurality of conductive plate-shaped bus bars and a resin mold section in which a plurality of conductive plate-shaped bus bars are partially embedded. In a method for manufacturing the bus bar assembly, firstly a plurality of conductive plate-shaped bus bars are disposed within a cavity formed by a die such as to be stacked in a thickness direction Z with a predetermined amount of space therebetween. Second, a first end and a second end of each bus bar are respectively supported by jigs in the width direction Y. Next, the cavity in the die is filled with the insulating resin and the plurality of bus bars are molded into a single body. After that, jigs are removed from the bus bars and jig placement portions are formed in the resin mold section.

First claim

What is claimed is:

1. A bus bar assembly, comprising:
a plurality of conductive plate-shaped bus bars and a resin mold section, wherein
the plurality of bus bars are stacked in a thickness direction with a predetermined amount of space therebetween;
the resin mold section is composed of an insulating resin and formed such as to mold the plurality of bus bars into a single body and provided with jig placement portions which were being suitable for placing jigs for respectively supporting a first end and a second end in a width direction perpendicular to the thickness direction of each bus bar, when the plurality of bus bars were molded by the insulating resin;
the jig placement portions comprise a first jig placement portion on the first end configured to have a concavity in a cross-section in parallel to the thickness direction and the width direction of the bus bar;
the jigs comprise a first jig configured to be placed by the first jig placement portion, and to support the first end not only in the width direction but also in the thickness direction;
the plurality of bus bars comprise a positive-electrode bus bar and a negative-electrode bus bar, each of the positive-electrode bus bar and the negative-electrode bus bar having a main surface perpendicular to the thickness direction; and
the positive-electrode bus bar and the negative-electrode bus bar are disposed such that the main surface of one of the positive-electrode bus bar and the negative-electrode bus bar faces the main surface of the other of the positive-electrode bus bar and the negative-electrode bus bar.

2. The bus bar assembly according to claim 1 , wherein the plurality of bus bars comprises at least three bus bars that are provided in the resin mold section of the bus bar assembly.

3. The bus bar assembly according to claim 1 , wherein:
the plurality of bus bars comprises at least two bus bars; and
the jig placement portions respectively corresponding to two bus bars of the plurality of bus bars disposed adjacent to each other are provided alternately with each other in a length direction perpendicular to the thickness direction and the width direction of the bus bar.

4. The bus bar assembly according to claim 3 , wherein the plurality of bus bars comprises at least three bus bars that are provided in the resin mold section of the bus bar assembly.
