Abstract

A power supply device (10) includes a case (30), a circuit board (50), a plurality of conductive terminals (60), and a plurality of securing members (40). The case includes a bottom plate (32). Each terminal is embedded in the bottom plate and includes a first end portion (66) extending into the case, and a second end portion (64) extending out of the case. The first end portion includes at least one receiving portion (62) disposed on a distal end thereof. Each securing member is mounted on the circuit board and includes at least one protrusion (48) received in the corresponding receiving portion.

Claims

1. A power supply device, comprising:

a case comprising a bottom plate;

a circuit board received in the case, the circuit board comprising a plurality of receiving holes therein;

a plurality of conductive terminals embedded in the bottom plate, each of the conductive terminals comprising a first end portion extending into the case and protruding through the corresponding receiving hole, and a second end portion extending out of the case; and

a plurality of U-shaped securing members extending through the receiving holes, each of the securing members comprising a pair of clipping portions at opposing arms of the U-shape respectively for fixing the conductive terminals therebetween;

wherein each opposing arm further comprises at least one first mounting tab and at least one second mounting tab, the at least one first and at least one second mounting tabs extending from distal ends of the clipping portion respectively, each of the at least one first and at least one second mounting tabs comprises at least one fixing portion bent from a distal end thereof, and the circuit board is latched between the fixing portions of the at least one first and at least one second mounting tabs.

2. The power supply device as claimed in claim 1, wherein each securing member further comprises a connecting portion connecting the pair of clipping portions.

3. The power supply device as claimed in claim 1, wherein each of the conductive terminals comprises a receiving portion therein, each of the clipping portions comprises at least one protrusion toward the opposite clipping portion, and when the conductive terminals are latched between the clipping portions, the protrusions are latched in the receiving portions.

4. The power supply device as claimed in claim 3, wherein each clipping portion defines a U-shaped hole partly surrounding the corresponding at least one protrusion, allowing resilient movement of the at least one protrusion relative to the clipping portion.

5. An electronic device, comprising:

a case comprising a bottom plate, a plurality of side walls connected to the bottom plate, and a cover mounted to the bottom plate and the side walls;

a circuit board received in the case, the circuit board comprising a plurality of receiving holes therein;

a plurality of conductive terminals embedded in the bottom plate, each of the conductive terminals comprising a first end portion extending into the case, and a second end portion extending out of the case, the first end portion comprising at least one receiving portion disposed on a distal end thereof; and

a plurality of U-shaped securing members extending through the receiving holes, each of the securing members comprising a pair of clipping portions at opposing arms of the U-shape respectively for fixing the conductive terminals therebetween;

wherein each opposing arm further comprises at least one first mounting tab and at least one second mounting tab, the at least one first and at least one second mounting tabs extending from distal ends of the clipping portions respectively, each of the at least one first and at least one second mounting tabs comprises at least one fixing portion bent from a distal end thereof, and the circuit board is latched between the fixing portions of the at least one first and at least one second mounting tabs.

6. The electronic device as claimed in claim 5, wherein each securing member further comprises a connecting portion connecting the pair of clipping portions.

7. The electronic device as claimed in claim 5, wherein each of the conductive terminals comprises a receiving portion therein, each of the clipping portions comprises at least one protrusion protruding toward the opposite clipping portion, and when the conductive terminals are latched between the clipping portions, the protrusions are latched in the receiving portions.

8. The electronic device as claimed in claim 7, wherein each clipping portion defines a U-shaped hole partly surrounding the corresponding at least one protrusion, allowing resilient movement of the at least one protrusion relative to the clipping portion.

9. An electronic device comprising:

a case enclosing said electronic device;

a circuit board received in said case, said circuit board defining a plurality of receiving holes therein;

a plurality of conductive terminals installable at said case to extend through a side of said case, each of said plurality of conductive terminals comprising a first end portion extending into said case to be reachable to a corresponding one of said receiving holes of said circuit board for extending through said corresponding one of said receiving holes, and a second end portion extending out of said case for further electrical connection therewith; and

a plurality of securing members installable beside said circuit board and electrically connectable with said circuit board, each of said plurality of securing members defining a receiving space therein beside said corresponding one of said receiving holes of said circuit board so that said first end portion of said each of said plurality of conductive terminals extending through said corresponding one of said receiving holes is able to be reachably placed in said receiving space to electrically connect with said circuit board exclusively through said each of said plurality of securing members, said each of said plurality of securing members is U-shaped, and each of opposite arms of said each of said plurality of U-shaped securing member define a clipping portion thereon, a protrusion extends from said clipping portion and toward the other clipping portion defined on the other of opposite arms of said each of said plurality of U-shaped securing member, a U-shaped hole is defined in said clipping portion around said protrusion of said clipping portion so that said protrusion is able to resiliently move relative to said clipping portion due to existence of said U-shaped hole around said protrusion, wherein each opposite arm further comprises at least one first mounting tab and at least one second mounting tab, the at least one first and at least one second mounting tabs extending from distal ends of the clipping portions respectively, each of the at least one first and at least one second mounting tabs comprises at least one fixing portion bent from a distal end thereof, and the circuit board is latched between the fixing portions of the at least one first and at least one second mounting tabs.
