Abstract

An electronic device includes: a connector that is to be electrically connected to a shunt resistor; a circuit board electrically connected to the connector; and a case within which the circuit board is provided and which has, at an outer side of the case, a base on which the shunt resistor is to be mounted and a protruding part provided apart from the base, the protruding part has a first protrusion on a leading end of the protruding part, and the base and the protruding part are to hold the shunt resistor interposed therebetween, and the first protrusion is to engage with the shunt resistor, whereby the shunt resistor is to be fixed in a state where the shunt resistor is connected to the connector.

Claims

1. An electronic device comprising:

a connector that is configured to be electrically connected to a shunt resistor;

a circuit board electrically connected to the connector; and

a case within which the circuit board is provided, an outer side of the case having;

a base on which the shunt resistor is to be mounted; and

a protruding part provided apart from the base, a leading end of the protruding part having a first protrusion,

wherein the base and the protruding part are configured to hold the shunt resistor interposed therebetween with the shunt resistor in direct contact with the base, and the first protrusion is configured to engage with the shunt resistor, whereby the shunt resistor is to be fixed in a state where the shunt resistor is connected to the connector.

2. The electronic device according to claim 1, wherein the protruding part has a second protrusion configured to press the shunt resistor when the first protrusion engages with the shunt resistor.

3. The electronic device according to claim 2, wherein a height of a leading end of the first protrusion from the protruding part is higher than a height of a leading end of the second protrusion from the protruding part.

4. The electronic device according to claim 3, wherein the base and the protruding part are arranged so as not to overlap each other as seen from above the case.

5. The electronic device according to claim 3, wherein the case is integrally formed.
