Protection

It is important to know that when designing electronic products, some holes are designed. Theoretically speaking, the design of these should have anti-edge equipment. The main reason is that the motors, resistors, and circuits in electronics and electrical appliances are relatively small. If dust enters accidentally, it may cause an electric short circuit. Modern electronic products, from flashlights that are as small as flashlights to computer and television equipment, have some plastic-shaped cushions. This kind of protection can play a very good protective effect. You can use this kind of cushion to plug it when you are not using it, to effectively prevent dust from entering.

Waterproof

Prevent water flow through the earphone jack and the charging port from entering the inside of the phone, thus affecting the use of the entire phone. Others can think of this problem, and mobile phone manufacturers must also think that useful USB dust coversdo have some waterproof effects, but if you throw the phone in the water, you plug ten USB dust covers that are useless. If it is normal to use and occasionally inadvertently water enters, then the general mobile phone charging port and earphone jack has a certain degree of waterproofing. It is not as convenient to blow it directly with a hairdryer instead of carrying a USB dust cover.

The USB dust cover is still very useful. At present, most smartphones have the earphone jack on the top of the fuselage, which means that if you don't open an umbrella when it rains, you just pick it up in the rain. For telephones, rainwater may enter the inside of the phone along the earphone hole, which may cause the earphone hole to short-circuit and keep the phone in the state of inserting the earphone, or in the worst case, the main board of the phone will burn.

However, the best way to protect your mobile phone is that you still don’t make phone calls on rainy days, so that the rain will not drip into the earphone jack. The USB dust cover of the mobile phone can play a good role, but sometimes it still depends on the usual maintenance will do.
