Resistor and current detection device
To provide a shunt resistor and a current detection device including the shunt resistor, to which a busbar, a board, and the like can be easily fixed with sufficient strength wherein only minimum processing of electrodes is required. Screwing members (bolt ( 14 ) and nut ( 15 )) that are separate members from electrodes ( 12 ) of the resistor ( 10 ), are fixed on the electrodes ( 12 ). The current detection device includes the shunt resistor ( 10 ), which has at least a pair of electrodes ( 12 ). One screwing member ( 14 ) fixed beforehand on at least one electrode ( 12 ) is screw fastened with the other screwing member ( 15 ) while disposing a prescribed intervening member ( 20 ) between the one screwing member and the other screwing member. Here, the prescribed intervening member ( 20 ) includes a board mounting a current detection circuit thereon and/or busbars.
1. A current detection device comprising:
a shunt resistor having at least a pair of electrodes;
one screwing member that is a separate member from the electrodes fixed on at least one electrode so as not to come off;
a second screwing member to be a pair of screwing members with the one screwing member;
a pair of voltage detection terminals provided on the pair of electrodes; and
a prescribed intervening member disposed and screw fastened between the one screwing member and the second screwing member,
wherein the prescribed intervening member is connected to the pair of voltage detection terminals.
2. The current detection device of claim 1 , wherein the prescribed intervening member is a board mounting a current detection circuit thereon.
