It is not dangerous for the data cable interface to be hot, it is a normal phenomenon; the reasons why the mobile phone data cable charging socket is often hot are: 1. The resistance of the charging cable is large; 2. When using fast charging, the current increases the heat generation It also increases; 3. The charger heats up, causing heat to be conducted to the wire.

Is the data cable interface dangerous to get hot?
normal phenomenon.
It is normal for the charger to heat up during the charging process of the mobile phone. The mobile phone charger is a parallel switching power supply. When working, the large transistor on the primary side is a big heat generator, so it will cause damage to the casing. Temperatures have also increased.
The temperature rise of the mobile phone charger is related to the load of the charger. During the charging process, the output current is larger, and the temperature of the charger will be relatively high, but it will not reach a hot temperature. After charging, even if the phone is still connected to the charger, the battery charging circuit is automatically cut off. The charger output current is very small, so the temperature increase is not very obvious. It may be that you used to unplug the charger after your phone was fully charged for a long time, so you no longer feel the heat.
The reasons why the charging socket of mobile phone data cables often get hot are as follows:
Reason 1: The resistance of the charging cable is large. According to the conductor heating formula, the heat generated is equal to the square of the current. By multiplying the resistance by time, we can see that the greater the resistance, the greater the heat generation while ensuring consistent charging current. The copper material used in some charging cables has greater resistance and smaller cross-section, resulting in greater heat generation.
Reason 2: When using fast charging, the calorific value increases as the current increases. For example, if the calorific value of 1A current charging is compared to 1, the calorific value of 2A charging is four times that of 1A.
Reason three: The heat generated by the charger causes heat to be conducted to the wire. The charger has a certain conversion rate when charging. Generally, the conversion rate is about 80%, and the remaining energy is dissipated in the form of heat energy. , and the copper wire in the charging cable is a good conductor of heat, causing the charging cable to also generate heat.
Extended information:
For the above three reasons, it is recommended to purchase branded data cables with good materials to reduce wire resistance, and use mobile phone chargers with high conversion efficiency and fast heat dissipation.
