Description

Technical Field

[0001] This utility model relates to the field of packaging structure technology of switching power supplies, and in particular to a rail-mounted modular power supply and its fasteners. Background Technology

[0002] Traditional modular power supplies with expansion packages consist of three independent parts: the power supply module, the expansion bracket, and the rail clips. When the power supply module needs to install the expansion package, the pins on the power supply module must be inserted into the circuit board of the expansion bracket, manually soldered and installed, and then the rail clips are locked onto the expansion bracket. This structure has the following drawbacks: 1. It includes three independent parts: the power supply module, the expansion bracket, and the rail clips, resulting in a wide variety of materials and high costs; 2. Each independent part needs to be manufactured and assembled separately, leading to complex processes and high production costs; 3. The power supply module and the expansion bracket are only connected and fixed by solder joints, which can easily loosen during use, resulting in poor performance; 4. Due to the fragmented nature of traditional modular power supplies with expansion packages, space utilization is low, limiting circuit board layout. Utility Model Content

There is a sealing notch between the baffles 1-2 at the two end openings of the outer casing 1 and the baffles at the slot positions. The upper surface of the mounting base has a protrusion corresponding to the wiring terminal positions for supporting and positioning the circuit board. The upper surface of the mounting base 3 has a baffle 3-9 on the outer side corresponding to the wiring terminal positions, which mates with the outer wall of the outer casing 1 to form a complete outer wall surface. The lower surface of the mounting base 3 has a guide groove 3-7, and the fastener 4 moves linearly along the guide groove 3-7 of the mounting base to achieve the snap-fit. The lower surface of the card holder 3 is provided with a curved boss 3-5; the fastener is provided with a latch 4-2 with a spring tab, and the latch 4-2 of the fastener cooperates with the boss 3-5 of the card holder to realize the latching and spring-back function.

The fastener also has three latches arranged in a triangle, including a large latch 4-2 with a spring clip and two small latches 4-4.

[0061] This utility model discloses a rail-mounted modular power supply, comprising a housing, a base, a circuit board, and a snap-fit ​​slider. The housing, base, and snap-fit ​​slider are all made of plastic, and the housing contains a cavity. A baffle is provided at the opening of the cavity, serving to limit and seal the circuit board. The circuit board has a slot, which engages with the baffle on the housing to achieve pre-positioning. The snap-fit ​​slider is mounted on the base, which has a protrusion. When the base and housing are assembled, the protrusion engages with the housing to secure the circuit board. This utility model, through structural optimization, integrates the modular power supply with extended packaging, reducing product components, simplifying the assembly process, and improving the automation level of product manufacturing. Therefore, this utility model's structure significantly reduces product cost and allows for greater product miniaturization.

[0062] The embodiments of this utility model will now be described in detail with reference to one example.

[0063] See Figure 1 The modular power supply of this utility model mainly consists of a shell 1, a circuit board 2, a base 3, and a snap-on slider 4.

[0064] See Figure 4 , Figure 5The outer shell 1 includes a first top plate 11 and a first side plate 12, as well as a second top plate 13 and a second side plate 14. The first side plate 12 and the second side plate 13 are at a certain demolding angle to facilitate production. A first slot 1-1 and a second slot 1-6 are provided on the second top plate 13 and the second side plate 14 of the outer shell. A slot 1-3 is provided on the outer shell 1. A slot retainer 1-4 and a retainer 1-2 are provided at the opening of the cavity 1-5 of the outer shell 1.

[0065] See Figure 6 The circuit board 2 is provided with a card slot 2-1.

[0066] See Figure 8 , Figure 9 The base 3 includes a buckle 3-1, a first protrusion 3-2, a second protrusion 3-3, a guide rail groove 3-4, a base boss 3-5, a base protrusion 3-6, and a buckle slider guide groove 3-7.

[0067] See Figure 10 For the snap-on slider 4.

[0068] See Figure 7 The retaining wall 1-2 on the outer shell and the slot 2-1 on the circuit board cooperate to install the circuit board 2 on the outer shell 1. The first terminal 2-2 on the circuit board can protrude from the outer shell through the first slot 1-1 on the outer shell, and the second terminal 2-3 on the circuit board can protrude from the outer shell through the second slot 1-6 on the outer shell, realizing the terminal wiring function. The slot retaining wall 1-4 set on the outer shell 1 isolates the slot 1-3 from the cavity 1-5. There is a gap 1-7 between the retaining wall 1-2 and the slot retaining wall 1-4. The gap 1-7 is sealed. When the glue is poured into the cavity 1-5 of the outer shell, the retaining wall 1-2 can prevent the glue from flowing into the first slot 1-1 and the second slot 1-2 of the outer shell, and the slot retaining wall 1-4 can prevent the glue from flowing into the slot 1-3. The gap 1-7 after sealing can prevent the glue from leaking out. This solution can accommodate more glue, so that the glue covers the circuit board 2. The glue can better assist the heat dissipation of the circuit board. At the same time, the glue can isolate the circuit board 2 from the external environment, and the product reliability is higher.

[0069] See Figure 11 The latching slider 4 moves along the guide groove 3-7 on the base in the direction indicated by the arrow. The protrusion 3-5 on the base cooperates with the latching slider 4 to realize the latching spring function. The protrusion 3-6 on the base can prevent the latching slider 4 from loosening. The guide groove 3-7 can prevent the latching slider 4 from loosening in the direction of the arrow. At the same time, the latching slider 4 can only move along the guide groove 3-7, that is, the latching slider 4 can only move in the positive or negative direction of the arrow.

[0070] See Figure 3The base buckle 3-1 and the outer shell slot 1-3 cooperate to realize the assembly of the base 3 and the outer shell 1. At the same time, the first protrusion 3-2 of the base, the second protrusion 3-3 of the base and the outer shell 1 work together to fix the circuit board 2.

[0071] See Figure 1 , Figure 2 The latch slider 4 and the base guide rail slot 3-4 work together to install the product on the guide rail 5.

[0072] As described above, a baffle 1-2 is provided at the opening of the cavity 1-5 of the outer casing 1; a slot 2-1 is provided on the circuit board 2; the slot 2-1 and the baffle 1-2 are matched to realize the pre-positioning of the circuit board 2.

[0073] The outer shell 1 is provided with a slot 1-3, and the base 3 is provided with a buckle 3-1. The slot 1-3 of the outer shell and the buckle 3-1 of the base are matched to realize the assembly of the outer shell 1 and the base 3.

[0074] A slot baffle 1-4 is provided at the opening of the cavity 1-5 of the outer shell 1, which isolates the slot 1-3 and the cavity 1-5.

[0075] There is a gap 1-7 between the retaining wall 1-2 and the slot retaining wall 1-4 on the outer shell 1.

[0076] The base 3 is provided with a first protrusion 3-2 and a second protrusion 3-3. When the outer shell 1 is assembled with the base 3, the first protrusion 3-2 and the second protrusion 3-3 are used to fix the circuit board 2.

[0077] The latching slider 4 is mounted on the base 3, and the base 3 is provided with a boss 3-5, a protrusion 3-6 and a latching slider guide groove 3-7 that restrict the movement of the latching slider 4.

[0078] The base 3 is provided with a guide rail slot 3-4. The guide rail slot 3-4 interacts with the buckle slider 4 to hang the module power supply on the guide rail 5.

[0079] Compared to traditional modular power supplies with extended packages, this invention integrates the traditional modular power supply housing and the extended package housing into a single design, eliminating the traditional modular power supply base. It also integrates the circuit board of the traditional modular power supply and the circuit board of the extended bracket. The guide rail clips are integrated into the base of the extended bracket, thereby reducing the number of product components, simplifying the assembly process, and increasing the automation level of product manufacturing. Therefore, this invention significantly reduces product costs, while also maximizing internal space utilization and resulting in a more compact product.

[0080] The above embodiments are only used to help understand the method and core idea of ​​this utility model. For those skilled in the art, other equivalent application schemes that can be naturally associated with the above description and examples without departing from the principle of this utility model, as well as some improvements and modifications to this utility model, all fall within the protection scope of the claims of this utility model.
