Manufacturing method of switch power supply housing

Abstract

The invention relates to a manufacturing method of a switch power supply housing. The switch power supply housing comprises a base and a cover which is detachably mounted on the base. The base is integrally U-shaped and comprises a base board, a left side board and a right side board. The base board is horizontally arranged. The left side board is vertically arranged and is connected with the leftend of the base board from the upper part. The right side board is vertically arranged and is connected with the right end of the base board from the upper part. The cover is integrally U-shaped andcomprises a top board, a front side board and a back side board. The top board is horizontally arranged. The front side board is vertically arranged and is connected with the front end of the top board from the lower part. The back side board is vertically arranged and is connected with the back end of the top board from the lower part. The base and the cover are provided with heat radiating holesand various mounting holes. The cover is detachably connected with a connecting board between the back side board and the base board of the base through a fastener. The main components of the base and the cover can be formed through one-time bending after punching and material falling. Under a precondition that high heat radiation effect is ensured, machining processes are remarkably reduced.

Description

[0001] This application is a divisional application of the application number: 201510096124.9, the name of the invention and creation is "Switching power supply enclosure and its manufacturing method", and the filing date is: March 4, 2015. Technical field [0002] The invention relates to a shell of a switching power supply formed by stamping and a manufacturing method thereof. Background technique [0003] With the rapid development of power electronic technology, the relationship between power electronic equipment and people’s work and life has become increasingly close, and electronic equipment is inseparable from reliable power supplies. In the 1980s, computer power supplies fully realized switching power supplies, and took the lead in completing computer Switching power supplies have entered various electronic and electrical equipment fields in the 1990s. Switching power supplies have been widely used in program-controlled switches, communications, electronic testing equipmen...

AI Technical Summary

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 least the second step during manufacture. The basic shape of the L shape is formed once, the plugging part is formed for the second time, and the fixed connection part is formed for the third time, a total of three times of bending, and the L-shaped base and cover will also limit the layout of the circuit board. For the base The connection with the cover body is fixed, and the space occupied by electronic components needs to be considered when planning the circuit layout of the circuit board
