A power-supply device comprising:
- a casing formed by metal stamping and having a space therein;
- and
- a circuit board disposed inside the casing,
- wherein the casing includes a casing portion having an opening, and a cover portion disposed to cover the opening of the casing portion,
- the casing portion has a through hole formed at a position corresponding to a connector terminal connected to the circuit board, and
- the casing portion has a non-flat portion provided to a region having a size greater than or equal to an outside diameter of a connector of an external connector line connected to the connector terminal in the casing portion, wherein
- the casing portion includes a body portion and a protruding portion, the protruding portion being part of a top face of the body portion that protrudes outward,
- the through hole is provided to a top face of the protruding portion, and
- the top face of the protruding portion includes at least a portion of the non-flat portion having at least one recess that at least partially surrounds the through hole for enhancing the stiffness of the metal stamped casing portion and thereby restricting deformation of the casing portion.
A power-supply device comprising:
- a casing made of metal and having a space therein;
- and
- a circuit board disposed inside the casing,
- wherein the casing includes a casing portion having an opening, and a cover portion disposed to cover the opening of the casing portion,
- the casing portion has a through hole formed at a position corresponding to a connector terminal connected to the circuit board,
- the casing portion has a non-flat portion provided to a region having a size greater than or equal to an outside diameter of a connector of an external connector line connected to the connector terminal in the casing portion,
- the metal casing has a thickness ranging from 0.3 to 3.0 mm for enabling metal stamping thereof, and
- the non-flat portion is configured to enhance the stiffness of the metal stamped casing portion for restricting deformation thereof.
