How to disassemble the charging head: Hot topics on the Internet in the past 10 days and disassembly guide
With the popularity of electronic devices, charging heads have become a daily necessity, and their safety and maintenance issues have become hot topics recently. The following are related topics that have been hotly discussed on the Internet in the past 10 days and a detailed guide to dismantling the charging head, covering tool preparation, step analysis and precautions.
1. Statistics of hot topics in the past 10 days
| Ranking | Topic keywords | Search volume (10,000) | Main platform |
|---|---|---|---|
| 1 | Charging head explosion accident | 45.6 | Weibo, Douyin |
| 2 | Quality comparison of third-party charging heads | 32.1 | Station B, Zhihu |
| 3 | DIY repair charger | 28.7 | Kuaishou, Tieba |
| 4 | Principles of fast charging technology | 19.3 | WeChat public account |
2. List of necessary tools for disassembling the charging head
| Tool name | Purpose | alternative |
|---|---|---|
| Phillips screwdriver | Remove housing screws | Slotted screwdriver (applicable to some models) |
| Crow bar/plastic card | Separate bonded shell | Wasted bank cards |
| Multimeter | Detect circuit faults | Requires professional operation |
| Anti-static gloves | Protect internal components | Use bare hands (not recommended) |
3. Detailed explanation of disassembly steps
Step 1: Security Check
Make sure the charging head has been powered off for at least 30 minutes to avoid residual high voltage in the capacitor. Wear anti-static gloves when operating.
Step 2: Remove the casing
① Observe the shell structure: Most charging heads are fixed with screws or ultrasonic welding.
② Screw-fixed type: Use the corresponding screwdriver to remove the screws (common in early products).
③ Ultrasonic welding type: Use a pry bar to slowly apply force along the joint (you need to be patient to avoid breakage).
Step 3: Internal Structure Analysis
| Component name | Function | Common failure points |
|---|---|---|
| Transformer | voltage conversion | Coil burned out |
| Rectifier bridge | AC to DC | diode breakdown |
| capacitor | Filter energy storage | Bulge leaking |
4. Precautions
①high risk warning: Non-professionals are not recommended to disassemble high-voltage parts (such as primary circuits).
② If the capacitor is found to have a bulging or burnt smell, stop using it immediately and scrap it.
③ Disassembly may result in loss of warranty qualification. It is recommended to contact the official after-sales service first.
5. Suggestions on recent hot topics
According to the hotly discussed topic on Weibo #chargerexplosionaccident#, users are advised to:
• Avoid buying copycat products under 20 yuan
• Regularly check whether the charging head is overheated
• Give priority to models with CCC certification
Through the above structured disassembly guide, users can initially determine the cause of the charging head failure. But it needs to be reiterated: when it comes to circuit repairs, the intervention of professional engineers is still the first choice.
