Nowadays, there are more and more types of household electronic products
The supporting data cable has also become a daily necessity
But it is easy to break after a long time of use
Many people will continue to use it
As everyone knows, danger lurks around...
A video posted on China's official fire department Weibo showed a broken charging cable charging a fire, and in just three minutes, the little Spark spread to the whole house.
Mr. Li's home in Nanyang, Henan Province, also suffered a similar disaster: the charger that was being charged suddenly exploded, and the monitoring recorded this thrilling scene.
Charging data cables have fire safety hazards, according to statistics, fires caused by electrical appliances have long ranked first in fire accidents in the mainland.
So, what kind of data cable is more dangerous? Which one should you usually buy?
After reading this article, you will know!
Get a simple look at the data cable
The regular data line contains 3 parts, from the outside to the inside: insulation quilt, shielded mesh, wire.
The material of the insulation quilt is PVC, TPE, nylon weaving, which is exposed to the outside for a long time, encountering light, gas, water, heat, sweat, microorganisms... Slowly it "ages".
The use of "aging" charging cables is very dangerous, and we must pay attention to observation when using them daily.
dangerous! Such a data cable must be lost
In daily life, the treatment of data lines must not be "new three years old three years of sewing and patching and repair for three years", once the following four situations occur, we must immediately throw them away! So as not to burn down the line and cause accidents.
1. The charging cable with damaged and creased appearance should not be used continuously! The data cable is damaged, the metal part inside will be exposed, this part of the corrosion resistance is poor, long-term exposure to the air may rust and corrode, resulting in excessive temperature during charging, it will burn the interface, causing fire.
2, charging when charging the contact part of the charging rate is normal, there is no contact is not good, if the contact is not good, it may be that the insulation between its contacts has been problematic.
3. When charging, the temperature at the terminal interface is overheated. Its insulating layer easily goes into a molten state. If there are combustible and flammable materials such as wooden tables and chairs, curtains, books and paper nearby, it is easy to cause fire hazards.
4. Data cable that does not meet professional standards. This line current is unstable, which can easily damage the internal structure of the mobile phone, damage the health of the battery, and damage the stored data.
And in line with professional standards of the line, the working current is limited, we most commonly use the 2.0 interface charging line, the current should be limited to 500 mA.
The appearance of the charging cable also has professional standards: the housing of the charger is required to be free of damage, and the combination of the cable and the plug is tightly fastened. The metal part of the plug is not rusted, deformed.
Tips for buying a new data cable
There are many fast-charging chargers on the market, and improper purchase can easily lead to safety hazards. We should pay attention to the following three points when purchasing:
First, try to choose the charging cable of TPE and PVC, these two materials are not easy to burn, even if there is a dangerous situation, you can also limit the spread of the flame.
Second, the charging cable, charging head and electronic product specifications must be adapted, we in the store to buy charging equipment, must explain what model the phone is, do not use the home mismatch in order to save money.
The third is not to be greedy, buy some three no products, be sure to see if the charging line has the logo certification of the China Quality Certification Center, and whether it is produced by regular manufacturers.
To sum up simply, it is to look at the material, look at the specifications, and look at the certification mark.
Finally, Xiaobian reminds you not to let a small charging data cable become a big hidden danger that threatens personal safety.
Quickly forward this article to your friends around you, and remind them that the old data cable must be replaced in time!
