Description

A mobile phone safety charging plug with timing function

technical field

The invention relates to a plug, in particular to a mobile phone safety charging plug with a timing function.

Background technique

Many people think that lightning rods have been installed on the roof of the building to ensure the safety of all our home appliances and lightning protection. In fact, this view is wrong. In fact, the lightning rod can only prevent direct lightning strikes, and can only protect buildings. When it is defending against direct lightning strikes, it will also release a large amount of induction lightning. The induction lightning released by the lightning rod will invade the interior of the electrical appliance along the antenna, feeder, signal line and power line in an instant, causing huge damage to the electrical appliance. Therefore, it is not enough to rely on lightning rods alone for lightning protection, and a three-level lightning protection system must be added. The so-called three-level lightning protection system refers to the lightning protection system of the building, the power lightning protection box in the floor and the indoor lightning protection socket. There are also some people who are used to turning off the TV, computer, etc. when the thunder and lightning start, thinking that this can ensure safety. In fact, this method can not protect security. Just turning off the power supply of electrical appliances cannot protect against lightning, because the ground wire is connected, and the strong current generated by lightning strikes is finally transmitted to the ground through the wires and electrical appliances, so just turning off the power supply of electrical appliances will still be passed through by the current. It goes underground, so simply turning off the power doesn't guarantee complete safety.

In daily life, people are increasingly inseparable from electronic devices. The use of electronic devices has become an indispensable part of people's life and work; mobile phones are also our portable backup treasures. When using them, accidents or early performance degradation And so on, are relatively higher than any electrical products in your home. If you have some basic knowledge of mobile phone first aid, you can save the life of your mobile phone by doing first aid before sending it for maintenance.

Maintenance of mobile phones is the most important thing. The so-called "prevention is better than cure". If you wait until the mobile phone has an accident every time, it may be too late. Battery damage is an example of mobile phones that are easy to wear out. If you can do it, you can keep your phone safe. Charging time should be enough, generally 5 hours is enough, if overcharging will shorten the battery life. At present, mobile phones on the market generally only need to be charged for two to three hours to be fully charged. But in real life, we always have various reasons, and we cannot pull out the fully charged mobile phone in time. Especially when charging the mobile phone before going to bed, we often disconnect the power supply the next morning, so long-term overtime will seriously affect the service life of the battery.

The mobile phone battery has a short service life due to charging and can be replaced, but the replacement cost is high, which is not conducive to sustainable development. Some users even caused bombing or fire accidents due to the battery charging time being too long, which is even more distressing. The mobile phone charger is actually a fragile part, and the internal components cannot withstand beatings. In particular, it is necessary to prevent accidental landing during use. Do not throw, knock or vibrate the charger. Rough handling of the charger will damage the internal circuit board. At present, the mobile phone charging plugs on the market are all designed for charging. There is no limit to the charging time, and there is no anti-drop design. It can be seen that having a mobile phone charging plug with a timing function is very important for the protection of the mobile phone battery. sex.
