Disassembling a burning iPhone data cable [Copy link]

 

  Last night, our data cable caught fire. The cable was placed in the office and of course plugged into the charger. I came to find out in the morning that the data cable was burnt and blackened. Are there any flammable materials on it? There are a lot of papers on the desk. If it caught fire, the company would have been burned by me last night. I am so scared! The head is clearly burnt black and the plastic is melted, but there is no fire. It should be that the charger is protected after the fire and there is no output, so there is no continuous fire. I have never bought a high-imitation cable. All Apple devices that use this cable are purchased from the Chinese version. So if there is no evidence to the contrary, I have to believe that this is an original cable. This cable has been used for several years, and there has been no prompt for accessory compatibility issues. Generally, non-Apple original cables will have prompts after using them for a period of time. However, since colleagues may borrow data cables and there is a possibility that they may have replaced the wrong cables, we cannot confirm whether it is an original cable. We can only disassemble it and let everyone identify it by themselves. Since there is a possibility that it is a non-original cable, this post does not constitute any appeal or accusation against the quality of Apple products themselves. Here are a few detailed pictures of the charging head. After careful observation, the cause of the fire was confirmed. Through careful analysis of the above pictures, all the contact copper sheets are smooth and have no abnormal overheating or short circuit marks. Therefore, the fire did not originate from the short circuit caused by the interface contacting other metal objects. The fire originated from the inside of the connector itself. Since the wire at the connector has not been used for a long time, the appearance of the wire is damaged, the skin is broken, and then there are traces of wire folding. The source of the fire is initially believed to be the mifi identification chip part, which is wrapped in metal and needs to be disassembled. Let's take a look at the workmanship of this line first! The USB head is made up of 6 strands of wire, three strands of red, green and white, and each with a strand of silver wire, and then there are a lot of anti-pull wires, a layer of shielding silver tape, and then a layer of metal braided mesh, and then the outside is plastic. Judging from the materials used in the wire, the workmanship is very good. Next, let's take apart the other end. Since the screenshots were taken while shooting the video, there are some issues with clarity, so just bear with it! The video is too big, so I won't upload it. Here are a few pictures for you to see, hhh After removing the plastic, the wires are still welded very steadily, and it is not a problem of welding falling off. The main problem is that the chip caught fire, and even the PCB was almost burned to slag, and the chips were indistinguishable. Let's not talk about it. Finally, I would like to remind everyone that safety is very important. Don't leave the charging circuit plugged into the plug board without taking it off. It doesn't consume much power, but it is more dangerous if your wire or charger is aging or there are quality problems with the charger. This post is mainly for safety warnings, and any form of reprinting and exaggeration of the content of this post is prohibited, including but not limited to all texts and pictures (except EEworld).

From today on, my Xiaomi router can no longer be plugged in all the time.

Safety first, I can't imagine if I burn down the company, will I be sentenced...

After carefully looking at all the pictures, I think your cable is the original one. You can contact Apple to get a new one and ask them to check why it caught fire.

I just leave my charger plugged in all the time. I'm used to it!

I also kept it plugged in and never unplugged it. I also used a counterfeit lighting cable.

Safety issues cannot be ignored

It burned like this, but no accident happened, it's a blessing in disguise

Hmm, it seems I have to pay attention to it in the future.

limale posted on 2018-1-12 17:47 Hmm, it seems I have to pay attention next time.

I just unplugged my Lightning cable from the socket. The Android cable is fine. The charger is not easy to contact flammable items in the socket. The Lightning data cable chip is on the plug. The position of the plug is not fixed. If it is placed on toilet paper or sheets, it will be a big trouble. Thanks for reminding me.

Fire is no small matter. A building worth billions of dollars could be set on fire. My power strips, monitors, etc. are always powered on. These generally don't generate heat. Routers and NAS are also always powered on.

If the knockoff cables are made like this, you probably won't make much money.

It's true that we need to develop good habits. I never plugged in my charger, thinking it would have no effect. But after this incident, I can't rest assured.

Yes! It’s really scary to think about it.

It is true that there are many risks in using electrical appliances for a long time, especially for such precision items. If there is a problem inside, it is difficult to find. If it is powered on for a long time, God knows what will happen one day.

For computers, monitors, routers, and NAS, few people will unplug the wires. However, large items generally have fireproof shells and fuses, and the lines also have short-circuit protection, which means that if a fire occurs, it will only burn inside and will not burn out. On the other hand, the charging cable does not have an automatic fuse protection mechanism, and it relies entirely on the protection mechanism of the charging adapter. The power of the charging adapter is also getting bigger and bigger, and it can provide high current support. According to "YDT1591-2009 Technical Requirements and Test Methods for Power Adapters and Charging/Data Interfaces of Mobile Communication Terminals", there are no special requirements for the data cable itself with chips. Logically, the iPhone data cable, because it has chips, needs more constraints. After all, chips are not as stable as pure wires. Of course, I don't know much about these standards, so I just checked them casually. If you know, please guide me.

The material of the charging cable plug should also be flame retardant, right?

Because you are charging, you can touch the charging head with your hand in the middle and find that it is hot. At the beginning of charging, it is fast charging with a slightly larger current. When it reaches 80% or is almost full, it will become trickle charging and the current will drop.

It didn't burn when it was charging, it burned when it was not charged and was not loaded.

Yes! Basically, they are all flame retardant. If they are not flame retardant, they may not look like this after burning. The key is that the wire with the chip should be treated differently from the wire.
