Problems solved by technology

The current switching power supply generally adopts an L-shaped base and a cover connected together up and down to form an overall rectangular shell-shaped shell, and the L-shaped base and cover must be connected together up and down in the manufacturing process. When it is necessary to increase the bending process to form the connecting plate part for connection, such as forming the socket part for connection through the bending process, then the L-shaped base and cover body need at leas

Example Embodiment

[0054] (Embodiment 1. Shell of switching power supply)

[0055] see figure 1 The housing of the switching power supply of this embodiment includes a base 1, a cover 2 detachably mounted on the base 1, and a connecting screw that fixes the base 1 and the cover 2 together. Both the base 1 and the cover 2 are stamped parts made of aluminum or steel.

[0056] see Figure 2 to Figure 5 , The base 1 is U-shaped as a whole, including a bottom plate 11, a left side plate 12 and a right side plate 13. The bottom plate 11 is arranged horizontally; the left side plate 12 is arranged vertically, connected to the left end of the bottom plate 11 from above; the right side plate 13 is vertical It is connected to the right end of the bottom plate 11 from above. The left and right sides of the bottom plate 11 are symmetrically provided with first heat dissipation holes 11-1 distributed at equal intervals along the axial direction, and the first heat dissipation holes 11-1 are in a waist shape. Th...

Example Embodiment

[0060] (Embodiment 2. Manufacturing method of the housing of the switching power supply)

[0061] The manufacturing method of the shell of the switching power supply obtained in Example 1 respectively includes the manufacturing method of the base 1 and the manufacturing method of the cover 2. The manufacturing method of the base 1 includes the following steps:

[0062] ①See Picture 10 , The preliminary shape of the base 1 is formed by blanking and punching using a progressive die process: the first heat dissipation hole 11-1, the second heat dissipation hole 11-2, the third heat dissipation hole 11-3, and the first limit hole 11 of the bottom plate 11 -6. The screw holes on the circuit board blocking plate 11-5, the connecting plate 11-7 and the connecting plate 11-7, and the mounting holes of the riveting stud 11-4 are all formed, and the mounting part 12-4 of the left side plate 12 , The second limiting hole 12-2 and the left connecting pin 12-3 have been formed, the connecting ...

Abstract

The invention relates to a switching power supply casing and a manufacture method thereof. The switching power supply casing comprises a base and a cover detachably mounted on the base, wherein the base wholly adopts a U shape and comprises a baseplate, a left side plate and a right side plate, the baseplate is horizontal, the left side plate is vertical and connected to the left end of the baseplate from above, and the right side plate is vertical and connected to the right end of the baseplate from above; the cover body wholly adopts a U shape and comprises a top plate, a front side plate and a rear side plate, the top plate is horizontal, the front side plate is vertical and connected to the front end of the top plate from below, and the rear side plate is vertical and connected to the rear end of the top plate from below; radiating holes and various types of mounting holes are formed in the base and the cover; and the rear side plate of the cover is detachably connected with a connecting plate of the baseplate of the base through a fastener. Main parts of the base and the cover can be subjected to one-step bending forming after stamping blanking, and the processing procedures are reduced remarkably under the premise that the radiating effect is guaranteed.

Description

technical field [0001] The invention relates to a shell of a punching-formed switching power supply and a manufacturing method thereof. Background technique [0002] With the rapid development of power electronics technology, the relationship between power electronic equipment and people's work and life is becoming increasingly close, and electronic equipment is inseparable from a reliable power supply. In the 1980s, the computer power supply fully realized the switching power supply, and took the lead in completing the computer. In the 1990s, switching power supplies entered various electronic and electrical equipment fields one after another. Program-controlled switches, communications, electronic testing equipment power supplies, control equipment power supplies, etc. have widely used switching power supplies, which has promoted the rapid development of switching power supply technology. . [0003] Usually, the switching power supply includes an aluminum alloy or steel c...
