Description

Technical Field

[0001] This utility model relates to a modular power supply magnetic component assembly fixture, belonging to the field of modular power supply technology. Background Technology

[0002] Modular power supplies are small in size, high in power, and widely used. Due to space constraints in the application of modular power supplies, their form factor is increasingly trending towards miniaturization. In order to accommodate more components on the PCB circuit board, make full use of the PCB area, and reduce the product height, components such as transformers and inductors are designed in a planar manner, that is, the windings are designed inside the PCB, and only the magnetic components need to be installed on the outside. This can reduce the height of the modular power supply as much as possible without changing the original PCB circuit board component distribution, thereby improving the overall space utilization of the end product. In contrast, traditional magnetic component assembly processes are inefficient and inconsistent. Summary of the Invention

Four height-limiting posts and four threaded holes are provided at the four corners.

[0006] By adopting the above technical solution, the position and height of the magnets can be accurately and consistently maintained.

[0007] As a preferred example, the magnet is a high-temperature resistant magnet with consistent size and magnetic force, and is embedded in the groove of the base boss.

[0008] By adopting the above technical solution, it is ensured that the magnetic force and position of the magnet remain unchanged during continuous use, thereby improving the consistency of the inductance of the module power supply magnetic components.

[0009] As a preferred example, the carrier plate is made of metal with a thickness of 4mm. It has an opening in the middle of the upper surface, four through holes at the four corners, four L-shaped limiting blocks and four positioning posts that are higher than the upper surface, several pins on the long sides, several openings in the middle corresponding to the base boss, and two slots on both sides.

[0010] By adopting the above technical solutions, the positioning accuracy of the module power supply PCBA is further enhanced, ensuring the positional accuracy of each magnetic component on the PCBA.

[0011] As a preferred example, the handle is a sheet metal part that passes through the slots on the left and right sides of the carrier plate and is assembled on the carrier plate; the positioning post and boss are embedded in the carrier plate, and the positioning post and boss are at the same height as the ejector pin; the L-shaped limiting block is assembled on the carrier plate by screws; the base and the carrier plate are assembled into a whole by the semi-threaded bolts.

[0012] By adopting the above technical solutions, the tooling manufacturing process is further optimized, making tooling manufacturing simple, efficient, and consistent, thereby ensuring the consistency of the module power supply magnetic component assembly effect.

[0013] As a preferred example, in practical application, the handles on both sides of the carrier board are lifted to raise the carrier board, the shape of the PCBA circuit board is aligned with the L-shaped limiting block, the positioning hole passes through the positioning post, and the PCBA circuit board is placed on the positioning post boss and the ejector pin; the two handles of the carrier board are lowered, the height of the carrier board is reduced, and the magnetic components on the PCBA are attracted together by the magnet to achieve the pressure required for magnetic component assembly. Then the whole is placed in a high temperature for curing to complete the magnetic component assembly process.

[0014] By adopting the above technical solution, the magnetic component assembly process of the module power supply is further optimized, and the magnetic component assembly process is simple and efficient.

[0015] The beneficial effects of this utility model are: by embedding high-temperature magnets on the base and embedding positioning posts, ejector pins, and L-shaped limit blocks on the carrier plate, the positioning is accurate, the pressure is consistent, and the operation is simple during the assembly of the module power supply magnetic components. This ensures high inductance consistency after the module power supply magnetic components are assembled, thereby improving the overall performance and mass production efficiency of the module power supply products.

[0023] The upper surface of the base 1 has several protrusions 11 that are higher than the surface in the middle, four height-limiting posts 13 and four threaded holes 14 at the four corners, and grooves 12 on the protrusions 11, into which magnets 2 are embedded; the surface of the carrier plate 3 has an opening 31 in the middle corresponding to the protrusions 11 of the base 1, slots 32 on the left and right sides, four through holes 33 at the four corners, four L-shaped limit blocks 5 and four positioning posts 6, and several ejector pins 7 on the two long sides. The handle 4 passes through the slot 32 and is assembled on the carrier plate 3. The half-threaded bolt 8 passes through the through hole 33 of the carrier plate 3 and is locked on the threaded hole 14 of the base 1, so that the carrier plate 3 and the base 1 are assembled into a complete tooling.

[0024] The base 1 is made of metal. Several protrusions 11 are provided in the middle of the upper surface, which are higher than the surface. Four height-limiting posts 13 are provided at the four corners, and four threaded holes 14 are provided. The protrusions 11 are provided with grooves 12. The whole is formed by CNC machining. The magnet 2 is embedded in the grooves 12.

[0025] The carrier plate 3 is made of metal. The center of the surface has an opening 31 corresponding to the boss 11 of the base 1. The left and right sides have slots 32, and the four corners have four through holes 33. It is CNC machined. Four L-shaped limit blocks 5 are locked to the carrier plate 3 by screws 51. Four positioning posts 6 and several pins 7 on the two long sides are embedded in the carrier plate 3. The handle 4 passes through the slot 32 and is assembled on the carrier plate 3.
