Why is the type-C interface big and thick?

First, the insertion end of type C is actually a female head, while the insertion end of the fruit machine is a male head. The reason why you think the type C interface looks big is that its insertion end is a female head and a sleeve. It should have a certain degree of reliability and firmness, so it should be thicker.

Secondly, usb3 came out with type-c 1, usb3 1 than usb3 The most direct change of 0 is that the speed can reach 10Gbps. To reach this speed, the first thing to solve is the problem of shielding.

All versions of USB ports are covered with a shell, which is not only fixed, but also shielded. The faster the bus speed, the higher the requirements for shielding. Therefore, the shell layer after layer outside type-C is mainly used to shield interference. Size and easy plugging are secondary. The primary problem to be solved is to ensure the reliable transmission of 10Gbps signals without interference. In fact, it's not impossible to remove the outer shell, but the speed must be reduced. It's not clear how much to reduce. Anyway, I'm in USB2 0 era, after removing the shielding of the connector, USB2 0 direct speed drop becomes usb1 1 level. It's really difficult to be fast and small. One party must make a little sacrifice.
