Capacitor unit, and electric compressor
A capacitor unit ( 20 ) includes: a harness side terminal ( 23 ) provided in a housing ( 22 ) for accommodating a capacitor main body therein and connectable to an electric power harness for supplying DC power from an outside; and a board side terminal ( 24 ) connectable to a circuit board from which the DC power is output via the capacitor main body. The board side terminal ( 24 ) extends in a plate shape from a base portion ( 24 b ) held in the housing ( 22 ) toward a distal end portion ( 24 a ) connected to the circuit board, and has a notch portion ( 40 ) recessed inward of the board side terminal ( 24 ) in a width direction between the base portion ( 24 b ) and the distal end portion ( 24 a ).
1. A capacitor unit comprising:
a housing that accommodates a capacitor main body therein;
a harness side terminal provided in the housing and connectable to a power source harness for supplying DC power from an outside; and
a board side terminal provided in the housing and connectable to a circuit board from hick the DC power is output via the capacitor main body,
wherein the board side terminal
extends in a plate shape from a base portion held in the housing toward a distal end portion connected to the circuit board, and
has a notch portion recessed inward of the board side terminal in a width direction between the base portion and the distal end portion, the notch portion having edge portions extending in a direction inclined with respect to a longitudinal direction of the board side terminal, and
has a curved portion extending in the width direction so as to be inclined with respect to a direction in which the hoard side terminal is inserted into a hole of the circuit board,
wherein the width direction is a direction orthogonal to the longitudinal direction and a thickness direction of the board side terminal, and
wherein a cross-sectional area of the curved portion orthogonal to the longitudinal direction is smaller than cross-sectional areas of the distal end portion and the base portion of the board side terminal orthogonal to the longitudinal direction.
2. The capacitor unit according to claim 1 ,
wherein a first notch portion formed on a first side of the board side terminal in the width direction and a second notch portion formed on a second side of the board side terminal in the width direction, are formed.
3. The capacitor unit according to claim 2 ,
wherein the first notch portion and the second notch portion are formed at an interval in a direction of connecting the base portion and the distal end portion to each other.
4. An electric compressor comprising:
the capacitor unit according to claim 1 ;
the circuit board that is configured to convert the DC power output from the capacitor unit into AC power;
a motor rotationally driven by the AC power output from the circuit board;
a compression mechanism driven by the motor; and
a casing that accommodates the capacitor unit, the circuit board, the motor, and the compression mechanism.
