The pin size of the TYPE-C patch under the usb3.1 specification is 24 pins, or the standard pin size should be 24 pins, but we often see 6-pin\/14-pin\/16-pin\/24-pin connectors on the Internet, and When looking at the product description or product name, it is not marked as simple c-type female connector or pin c-type female connector.

In fact, 12pin\/16Pin is also a full-pin TYPE-C patch, which actually only integrates some related signal pins. At the beginning of the design of the C-type female connector, the designer will actually design more pin sizes to cope with the new technologies of the future.

With the development of technology, more pin-type pins will be reserved in the future, leaving room for future adjustments. Because the TYPE-C patch was originally designed to use the interface standard for more than ten years. At this time, take a look at the TYPE-C C SMD interface, you can understand the pin layout of the single row pin jumper, 6p or 12P or 14p or 16P or 24p is just a different name, it is essentially the same specification, if you look closely, you will find a single row of 16 The 4-pin pins at the beginning and end of the pin C female connector are connected in pairs, so people will mistake it for a 12-pin pin, when in fact, it is a 16-pin full-pin type with full functionality.

The TYPE-C patch supports functions such as double-sided plugging, high-power charging, high-speed transmission, etc. In fact, using a single-row 16P pin patch has its natural advantages. First, retaining the necessary pins can make full use of the interface ( Actually, many Type C female sockets have 24 pins, but only perform double-sided insertion and high-current charging functions. -rowpin 16pin\/12pin is very reasonable). Second, for production line personnel, whether it is a real-time quality inspector of the production line Or offline NG product maintainers, single row pin type C female sockets are also more beneficial. Single row pin type C type female sockets are easier to detect if it is caused by wrong soldering, wrong soldering or soldering. With 24 It is easier to detect than a pin double row patch. The same goes for maintenance personnel. In many cases, the PCBA can be repaired without disassembling the entire TYPE-C patch.
