Type-C has gradually become the mainstream interface for electronic devices due to its advantages of not distinguishing between front and back, compactness and slimness. Except for Apple, which wants to sell more adapters, most flagship mobile phones on the market use it. Of course, many people may be more familiar with Type-C by its other name: "Huawei mouth".
Although the term "Huawei mouth" is not accurate. Huawei is not the first manufacturer to use Type-C, nor is it its inventor. However, it is undeniable that many people see Type-C for the first time. The interface is on Huawei's mobile phones, and over time it has become a conventional name.
But Huawei’s contribution to Type-C is not just to promote the interface with its strong brand influence. A recently disclosed patent shows that Huawei has also developed a method to prevent corrosion of the Type C interface.
Although Type-C is easy to use, it is very easy to wear during actual use. This is related to the CC pin inside the interface.
In Type-C, the CC pin is used to detect whether a device is inserted. In mobile terminals, it usually needs to be kept charged. Once water vapor, sweat, dust, etc. enter the interface, it is easy to cause CC Electrochemical corrosion occurs between pins and other pins.
Huawei's patent titled "This method of preventing corrosion of terminals and Type C interfaces" provides a solution. To put it simply, the motion sensor is used to detect the motion status of the terminal, and the processor determines whether to configure the CC pin to low-level mode, thereby reducing the chance of electrochemical corrosion between the pins caused by moisture under high-level conditions.
Huawei’s P series and Mate series are both waterproof. When users are exercising, sweat and other substances may penetrate into the interface. This patent is expected to improve the waterproof capabilities of the device from the inside out.
However, is Huawei spending so much effort on the Type-C interface just to improve its anti-corrosion problem?
Will one day Huawei define anti-corrosion interfaces or even other new interface standards? Just like Apple's 30-pin interface and the lightning interface that it still stubbornly uses today, it doesn't seem surprising that Huawei, which also has strong control over its own products and has gradually improved its ecology, has become the maker of new interface standards. thing.
