Abstract

In a metal plate resistor, the bonded surface between the resistance body and the electrode can be prevented from peeling off. The metal plate resistor comprises a resistance body; an electrode consisting of metal material having a higher conductivity than the resistance body, and the electrode bonded with the resistance body; a recessed portion formed in an end face of the electrode on a side bonded with the resistance body; and a fixation hole formed in the electrode for inserting a bolt; wherein an end portion of the resistance body is fitted into the recessed portion in the electrode. The recessed portion is provided with wall portions on both sides in a width direction of the resistance body, and in a direction substantially perpendicular to a penetration direction of the fixation hole. The recessed portion is opened to an end face and a first surface of the electrode.

First claim

The invention claimed is:

1. A metal plate resistor comprising:
a resistance body consisting of metal material;
an electrode consisting of metal material having a higher conductivity than the resistance body, and the electrode bonded with the resistance body;
a recessed portion formed in an end face of the electrode on a side bonded with the resistance body; and
a fixation hole formed in the electrode for inserting a bolt;
wherein an end portion of the resistance body is fitted into to the recessed portion in the electrode;
wherein the recessed portion is provided with wall portions on both sides in a width direction of the resistance body, and in a direction substantially perpendicular to a penetration direction of the fixation hole;
wherein the recessed portion is opened to an end face and a first surface of the electrode; and
wherein the recessed portion has a bottom surface, which is provided with a voltage detection terminal hole, which penetrates from the first surface to the second surface opposite to the first surface.

2. The metal plate resistor of claim 1 , wherein a voltage detection terminal is flange-shaped so that an end thereof contacts to the bottom surface.
