Abstract

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 ).

Claims (20)

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.
