Current detection apparatus
First Claim
1. A current detection apparatus for detecting a current from a battery flowing through a harness, comprising:
- a resistor having a current carrying member disposed between a terminal of the battery and the harness to provide a current carrying path therebetween;
a circuit board provided thereon with a current detection circuit for detecting a current flowing through the current carrying member on the basis of a potential difference between two positions along the current carrying member; and
a casing having a recessed portion for accommodating therein the circuit board;
a cover for closing the recessed portion of the casing to form an enclosure;
wherein the circuit board includes solder junctions between the circuit board and respective terminals of a plurality of terminals protruding from an inside bottom of the recessed portion and passing through respective through holes arranged on the circuit board, one of the plurality of terminals being electrically connected to the current carrying member at one of the two positions along the current carrying member, another one of the plurality of terminals being electrically connected to the current carrying member at the other of the two positions along the current carrying member, andan open end of the recessed portion that is engaged with the cover lies in a single pane tilted relative to the circuit board so that a portion of the circuit board that includes the solder junctions lies completely outside the recessed portion.

Abstract
A current detection apparatus for detecting a current from a battery flowing through a harness. The apparatus includes a resistor having a current carrying member disposed between a terminal of the battery and the harness, a circuit board provided thereon with a current detection circuit for detecting a current flowing through the resistor, and a casing having a recessed portion for accommodating the circuit board, a cover for closing an opening of the recessed portion. The circuit board includes a solder junction between the circuit board and a terminal protruding from an inside bottom of the recessed portion and passing through a through hole arranged on the circuit board, and an open end of the recessed portion that can be engaged with the cover is non-parallel to the circuit board so that at least a portion of the circuit board including the solder junction lies outside of the recessed portion.
