Abstract

A power-supply device including: a casing having a space therein and formed by metal stamping or having a thickness ranging from 0.3 to 3.0 mm; 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 a non-flat portion is 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.

First claim

The invention claimed is:

1. 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.

2. The poser-supply device according to claim 1 ,
wherein the region having the size greater than or equal to the outside diameter of the connector is defined by a circle having a diameter greater than or equal to 15 mm.

3. The power-supply device according to claim 1 ,
wherein the circuit board is fixed to the cover portion.

4. The power-supply device according to claim 3 ,
wherein a groove is formed in an inner face of the cover portion to surround the circuit board.

5. The power-supply device according to claim 1 ,
wherein the connector terminal is fixed to a coupler base provided to the circuit board, and
the coupler base is provided to a portion where the protruding portion is formed.

6. The power-supply device according to claim 1 ,
Wherein the top face of the body portion includes at least one ridge portion for enhancing the stiffness of the casing portion.

7. A light fixture comprising:
a housing including a light extraction portion;
a light source disposed inside the housing; and
the power-supply device according to claim 1 that is disposed outside the housing and supplies power to the light source.

8. A vehicle comprising:
a vehicle body; and
the light fixture according to claim 7 .

9. The power-supply device according to claim 1 ,
wherein a groove in the casing portion at least partially surrounds the through-hole, the groove being configured to receive the connector.

10. The power-supply device according to claim 9 ,
wherein the groove includes a seal material for sealingly engaging the connector.

11. 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.

12. The power-supply device according to claim 11 ,
wherein the cover portion has a thickness ranging from 0.8 to 3.0 mm, and the casing portion has a thickness ranging from 0.3 to 1.0 mm.
