Voltage detection unit and power storage device
A voltage detection unit includes a voltage detection terminal having a first location being conductively connected to a detection target, a board-shaped housing having a terminal accommodating recess in which the voltage detection terminal is accommodated, a cover locked to the housing at a first temporary locking position where the first location of the voltage detection terminal accommodated in the terminal accommodating recess is not covered and a final locking position where the first location is covered, and an electric wire conductively connected to a second location of the voltage detection terminal and drawn out toward the outside of the housing. The housing includes a guide portion guiding the cover from the outside toward the first temporary locking position, and a first wall abutting on the cover when the cover is positioned at the first temporary locking position in a moving direction in which the cover is guided.
1 . A voltage detection unit comprising:
a voltage detection terminal that has a first location being conductively connected to a detection target;
a board-shaped housing that has a terminal accommodating recess in which the voltage detection terminal is accommodated;
a cover that is locked to the housing at a first temporary locking position where the first location of the voltage detection terminal accommodated in the terminal accommodating recess is not covered and a final locking position where the first location is covered; and
an electric wire that is conductively connected to a second location of the voltage detection terminal and drawn out toward the outside of the housing, wherein
the housing includes
a guide portion that guides the cover from the outside toward the first temporary locking position, and
a first wall that comes into contact with the cover when the cover is positioned at the first temporary locking position in a moving direction in which the cover is guided and moves toward the first temporary locking position.
2 . The voltage detection unit according to claim 1 , wherein
the cover is locked to the housing at a second temporary locking position that is different from the first temporary locking position and does not cover the first location, and
the housing includes a second wall that comes into contact with the cover when the cover is positioned at the second temporary locking position in a moving direction when the cover is moved from the first temporary locking position toward the second temporary locking position.
3 . The voltage detection unit according to claim 2 , wherein
the cover comes into contact with the first wall of the housing when the cover is positioned at the final locking position in a moving direction when the cover is moved from the second temporary locking position toward the final locking position.
4 . A power storage device comprising:
a board-shaped conductive module that includes the voltage detection unit according to claim 1 and a conductive board as the detection target to which the voltage detection terminal is conductively connected; and
a power storage module that is charged and discharged, on which the conductive module is stacked.
