The type-c motherboard has a brand new interface size and a slightly cool name, making it easy for first-time listeners to think that this is a brand new USB standard, but in reality it is not. The type-c motherboard is only a part of the USB 3.1 standard, not a new standard.

The birth of the type-c mother seat was not long ago, and the rendering of the type-c connector was released at the end of 2013. It was already finalized in the 2014 USB 3.1 standard. It is a new specification for USB cables and connectors, and a complete set of new USB physical specifications.

It is as lightweight and compact as the Lightning interface in iPhone phones, and can be expanded into three interfaces: power/USB transmission/VGA or HDMI. Through the adapter, it can also be compatible with previous generation interfaces such as USB 3.0 and USB 2.0.

It should be noted that similar to the common USB 2.0, the USB 3.1 standard still has interfaces such as type-a (commonly used in computer hosts) and type-b (commonly used in Android phones), so type-c is only one type of high-speed data transmission in USB 3.1, not the only one.

The characteristics of the type-c mother seat are as follows:

1. The type-c mother seat supports the "front and back insertion" function that can be inserted from both sides, and can withstand 10000 repeated insertion and removal;

2. The maximum data transmission speed of the type-c bus is 10Gbit/s, which is also the standard of USB 3.1;

The size of the socket end of the type-c mother base interface is approximately 8.3mm × 2.5mm slim design;

4. The standard specification connection cable equipped with a type-c connector can pass a current of 3A-5A, and also supports a "USB PD" with USB power supply capacity, which can provide up to 100W of power. It is compatible with supporting data audio devices, power supplies, and other interfaces.

5. Type-C mother seat miniaturization support, with bidirectional high-speed data transmission in the data mode, and its two channels can also support up to 20G/S.

6. The type-c motherboard can also be compatible with the USB 2.0/3.0 specification. For different USB motherboard interfaces, it can be achieved through switching.

The overall structure is more compact, more durable, beautiful in appearance, and small and exquisite. The fixing component fixes the shielding card, avoiding the loosening and deformation of the shielding card after repeated insertion and unplugging of the type-c male head and the type-c female seat for a long time, thereby avoiding damage to the EMC steel sheet of the type-c male head caused by the deformation of the shielding card of the type-c female seat.

The disadvantages of type-c mother seat are as follows:

1. The spacing between the type-c mother pin and PIN is small, which can easily cause some hair, debris, etc. to enter and cause a micro short circuit between the vbus and GND at the charging terminal;

The structure of the type-c base is relatively complex, and machining accuracy issues can also lead to unstable contact resistance;

3. Multiple insertion and insertion of the type-c mother base can lead to an increase in resistance.
