Because of the reasons such as playing while charging or carrying around, the phenomenon of loose charger interface is not rare. This situation is mostly because the USB-A interface is unwelded or there is a foreign body inside.
< br >
loose weld
< br >
The plug or interface welding is mostly related to the quality of the charger and the user's use habits.
< br >
< br >
Poor quality chargers because ordinary PCB boards are used and the solder used for welding has a low melting point. In the subsequent use process, because of thermal expansion and contraction or artificial drop, the interface pin and the PCB board are welded, and finally loose.
< br >
< br >
Again, because users like to charge while playing. In the process of charging the phone, the charger interface will become loose because of the shaking of the data cable, and eventually lead to the internal interface welding.
< br >
< br >
Use tweezers to hold the metal shell of the charger interface, shake it hard, if the interface has obvious shaking, that is, there is a dewelding phenomenon of the interface, just disassemble the charger, and use the soldering iron to solder the pin, you can solve the problem.
< br >
Foreign bodies exist on the interface. Procedure
< br >
The foreign body in the charger interface is mostly clothing fibers, tobacco and other objects, which is mostly related to the user's living habits.
< br >
< br >
Most users like to carry chargers and data cables with them, such as in their pockets and bags. In this case, objects such as clothing fibers and tobacco are very easy to enter the charger interface, and each time the data cable is inserted and removed, these objects will be piled deep in the interface. In the long run, foreign bodies will block the interface of the charger, and then the data cable can not be fully inserted into the charger, resulting in poor contact and loose phenomenon.
< br >
< br >
In this case, only when the charger is not powered on, use tweezers or other sharp objects to pull out the relics in the charging head interface to solve the problem.
If the charging head and socket are loose, try the following methods: 1. Replace the charging cable or charger head, use the original charger as much as possible, and ensure that the interface between the charger and the charging cable matches. 2. Check whether there is any loose or impurities inside the socket. If there is, use a small brush or a cleaning cotton swab to clean it up. 3. After turning off the phone or electronic device, try gently adjusting the charging cable or charger by hand to see if it can be more firmly inserted into the jack. In short, it is recommended to use the original charger and cable, and take care to keep the inside of the jack clean.
If the problem still cannot be solved, you can contact after-sales or professional technical personnel for maintenance.
If the charging head and socket are loose, deal with them in time. 2. If the charging head and jack are loose, sometimes it will lead to the power cannot be full or the charging speed is slow, and the long-term use of loose will shorten the life cycle of both.
If not handled in time, it may cause inconvenience and impact on the use, and even have a negative impact on the service life of electrical equipment. 3. In use, some simple methods can be used, such as cleaning the plug with a thin brush, and using paper or tape to firm the plug, or using some professional tools to strengthen the plug, which can solve the problem of loose plug.
If the loosening is serious, you need to consider replacing the plug or device.
Pull the plug on the phone and plug it in again. Try to plug it in again. Gently debug the jack with your hand. Find the right Angle.
< br >
If that doesn't work, try another cable. See whether it is the problem of the data cable or the phone interface.
< br >
If the problem is the phone port, dust the interface. Use a small cotton swab, apply some alcohol, and gently wipe the interface.
< br >
It may be that the accessories inside are loose. Gently touch the interface with the scissors twice to adjust its position.
< br >
If the above operations are not useful, we will send to repair! If the mobile phone is under warranty, it is free, and if it has passed the warranty period, it may need to pay a certain fee.
< br >
On weekdays, when charging a mobile phone, we must pay attention to protect the jack, do not plug in and out at will when charging, and regularly dust treatment.
Simple, the general mobile phone charger is locked with a phillips screw, Apple and the like use a hidden button, the phillips screw is created a screwdriver to unscrew.
< br >
Hidden button with nails or too difficult can use nail clippers to pry open, but I can not guarantee that the appearance is damaged after opening with a soldering iron to weld the solder back, if there is no soldering iron but the shell is loose can be glued, but the line short can also find an iron wire, it is best to drink the home cable is about thick (the cable's skin is about 20cm thick). Get the fire burning red (it is best to use something to hold, the hand will not be burned), and then immediately touch the red end of the usb female port where the welding, see the solder melt and the circuit board and usb head together can be released, but the solder to be completely cooled by hand, like the candle cooling. Finally, be safe.
The mobile phone charging head is loose. It is recommended to go to the repair shop for repair. Mobile phone chargers can be roughly divided into travel chargers, seat chargers and maintenance chargers, and the average user is mainly exposed to the first two. The biggest seller on the market is the travel charger. There are also a variety of forms of travel chargers, common inexpensive duck egg type miniature travel charger, ordinary desktop card charger, high-end desktop charger with liquid crystal display. ,
It is recommended to replace the data cable and the cost of replacing the charging head is higher.
1, first check whether the charging cable jack problem, if no problem, see the next step.
2, again check whether there is dust in the type-c interface on the phone, if there is the problem. Due to a lot of dust, the charging cable jack is not inserted in place, resulting in loose, not tight, easy to drop and other problems. First find the card needle or sewing needle that comes with the phone, and then gently swipe the card against the quasi-interface hole until the dust is clean
