Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, specifically a power adapter with a sealed snap-fit ​​structure. Background Technology

[0002] A power adapter is a crucial power supply device that converts AC mains power into a voltage suitable for electronic devices. Its core consists of a main casing, component housings, and wiring parts. Widely used in various electronic devices such as computers, mobile phones, and home appliances, its function is to ensure a stable and safe voltage supply to these devices. The adapter's sealing, ease of installation and removal, and wiring stability directly affect the lifespan of its internal components, operational safety, and maintenance efficiency, making it an indispensable core component in electronic device power supply systems.

[0003] Existing power adapters have many obvious shortcomings in use. On the one hand, their sealing performance is poor, and the connection between the main body and the top cover is not tight, making them susceptible to dust and moisture intrusion, which can cause internal components to become damp and damaged or have poor contact, affecting the stability of power supply. On the other hand, the disassembly and assembly process is cumbersome, relying heavily on screw fixing or integrated design. During maintenance, tools are required for disassembly, making it inconvenient to quickly replace faulty components or damaged wiring, which increases maintenance costs and time.

[0004] The purpose of this invention is to provide a power adapter with a sealed snap-fit ​​structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power adapter with a sealed snap-fit ​​structure, including a main body shell, a component core disposed inside the main body shell, a disassembly and assembly mechanism disposed on the top of the main body shell, and locking mechanisms disposed on the left and right sides of the main body shell.

[0006] The disassembly and assembly mechanism includes a sealing component, a sealing component, and a support component. The sealing component is located on the top of the main body shell, the sealing component is located between the sealing component and the main body shell, and the support component is located inside the main body shell.

[0007] The locking mechanism includes a wiring assembly and a locking assembly. The wiring assembly is located on the left and right sides of the component core, and the locking assembly is located on the left and right sides of the main body shell.

A positioning block is fixedly connected to the bottom of the second flange, and the positioning block is engaged inside the first flange.

[0010] Preferably, the support assembly includes a support fin plate, which is fixedly connected to the bottom of the main body shell. The top of the support fin plate is in contact with the bottom of the component core. A fixing strip is provided above the support fin plate and is fixedly connected to the bottom of the top cover. The bottom of the fixing strip has rubber strips on both the protrusion and concavity, and the bottom of the rubber strips is in contact with the top of the component core.

[0011] Preferably, the wiring assembly includes a plug, which is snapped into the left and right sides of the component core, and a connecting wire is fixedly connected to the outside of the plug.

[0020] This utility model provides a technical solution: Example

[0021] Combination Figures 1 to 4 A power adapter with a sealed snap-fit ​​structure includes a main body shell 3, a component core 4 inside the main body shell 3, a disassembly and assembly mechanism 1 on the top of the main body shell 3, and locking mechanisms 2 on the left and right sides of the main body shell 3.

[0022] The disassembly and assembly mechanism 1 includes a sealing component 11, a sealing component 12, and a support component 13. The sealing component 11 is disposed on the top of the main body shell 3, the sealing component 12 is disposed between the sealing component 11 and the main body shell 3, and the support component 13 is disposed inside the main body shell 3.

[0023] The sealing assembly 11 includes a top cover 1101, which is snapped onto the top of the main body shell 3. A retaining plate 1102 is fixedly connected to the left and right sides of the top cover 1101, and the retaining plate 1102 is snapped into the top of the left and right sides of the main body shell 3. The sealing assembly 12 includes a first flange 1201, which is fixedly connected to the inner edge of the top of the main body shell 3. A second flange 1202 is provided above the first flange 1201, and the second flange 1202 is fixedly connected to the bottom of the top cover 1101 and the inner side of the retaining plate 1102. The bottom of the second flange 1202 is fixedly connected to... There is a positioning block 1203, which is engaged in the protrusion 1201. The support component 13 includes a support fin 1301, which is fixedly connected to the bottom of the main body shell 3. The top of the support fin 1301 is in contact with the bottom of the component core 4. A fixing strip 1302 is provided above the support fin 1301. The fixing strip 1302 is fixedly connected to the bottom of the top cover 1101. The bottom of the fixing strip 1302 has rubber pressure strips 1303 on both the protrusion and concave sides. The bottom of the rubber pressure strip 1303 is in contact with the top of the component core 4.

[0024] Furthermore, the support fins 1301 and the fixing strips 1302 support and fix the component core 4 on the upper and lower sides respectively, so that the component core 4 is enclosed in the main body shell 3, while reducing the contact area between the component core 4 and the main body shell 3, thus improving the heat dissipation effect of the component core 4 during operation. Example

[0025] See Figures 1 to 5 Furthermore, based on Embodiment 1, the locking mechanism 2 includes a wiring assembly 21 and a locking assembly 22. The wiring assembly 21 is disposed on the left and right sides of the component core 4, and the locking assembly 22 is disposed on the left and right sides of the main body shell 3.

[0026] Wiring assembly 21 includes a plug 2101, which is snapped into the left and right sides of component core 4. A connecting wire 2102 is fixedly connected to the outside of the plug 2101, and a reinforcing sleeve 2103 is fixedly connected to the outer ring of the connecting wire 2102. The reinforcing sleeve 2103 is fixedly connected to the outside of the plug 2101. Locking assembly 22 includes a semi-screw a 2201, which is fixedly connected to the outside of the locking plate 1102. A semi-screw b is provided below the semi-screw a 2201. 2202, the semi-screw tube b2202 is fixedly connected to the left and right sides of the main body shell 3. The bottom of the semi-screw tube a2201 and the top of the semi-screw tube b2202 are in contact with each other. The semi-screw tube a2201 and the semi-screw tube b2202 are sleeved on the outer ring of the reinforcing sleeve 2103. The outer ring of the semi-screw tube a2201 and the semi-screw tube b2202 are threadedly connected to the threaded cylinder 2203. The outer side of the threaded cylinder 2203 is fixedly connected to the sleeve 2204, and the sleeve 2204 is sleeved on the outer ring of the reinforcing sleeve 2103.

[0027] Furthermore, operators can control the connection or unlocking between the threaded cylinder 2203 and the semi-screw tubes a2201 and b2202 simply by rotating the threaded cylinder 2203. This facilitates locking or disassembling the top cover 1101 and the main housing 3, and also makes it easier for operators to replace the connecting wire 2102. This ensures that the connecting wire 2102 and the component core 4 are independent of each other, and damage to a single structure will not affect the subsequent use of the equipment as a whole, making it convenient for operators to use.

[0028] In actual operation, when this device is in use and it is necessary to disassemble the component core 4, the operator first rotates the threaded cylinders 2203 on both sides. The threaded cylinders 2203 rotate outward around the outer ring of the semi-screw tubes a2201 and b2202. The outward movement of the threaded cylinders 2203 releases the connection with the semi-screw tubes a2201 and b2202. At this time, the locking between the clamping plate 1102 and the main body shell 3 is released. Then the operator can move the top cover 1101 upward to release the connection between the top cover 1101 and the main body shell 3. Subsequently, the operator can replace the component core 4 inside the main body shell 3, or continue to plug and unplug the connecting wires 2102 on both sides of the component core 4 for replacement.
