Type-C interface waterproof detection requires individual products to have grooves on the edges and slots inside, which requires higher requirements for fixture design. Moreover, type-C has a small size and a large number of products, making it easy for the upper and lower parts to take up time. In order to improve the efficiency of airtightness and waterproofing testing for the C interface, there are 2-4 testing ports on the fixture according to requirements, which means that the airtightness and waterproofing of four C interfaces can be tested simultaneously. The airtightness and waterproofing tester equipment is a conventional waterproofing testing machine. If the USB C interface needs to meet the IP67 standard, then a pressure of around 10.5~20kPa can be used for testing, which can effectively ensure the quality of the type-C interface product.

The type-c interface is a new form of USB interface. The degree is 8.3 millimeters and the thickness is 2.5 millimeters. This type of interface has a total of 24 pins, and when there are 12 pins on each side, there is no need to distinguish between the front and back sides. It can be inserted freely, and the interface has no directionality, allowing users to avoid incorrect insertion during use. The general abbreviations include USB C, type-C, etc. These refer to the same product. The USB 3.0 interface usually has 9 to 11 pins, while USB 2.0 only has 4 pins. The increase in pins did not lead to a larger volume of the type-c interface, but in fact, it also reduced its size, meeting the needs of mobile devices. New interface design with dimensions of approximately 8.4mmx2.6mm, slim interface power output capacity: standard cable 3A, interface 5A, can be used to transmit DisplayPort signals, support 4K UHD image transmission, can provide up to 100 power transmission, better electromagnetic interference (EMI) and radio frequency interference (RFI) mitigation characteristics, support front and back insertion, can withstand 10000 repeated plugging and unplugging, USB Power Delivery, can support charging, The maximum data transmission speed can reach 10Gbps. Based on the USB specification, the standard connection cable equipped with type-c connector can pass 3A current. At the same time, it can also support the USBPD that exceeds the existing USB power supply capacity. It can provide a maximum of 100W force DisplayPort alternating mode, and support the resolution of up to 4K Ultra High Definition (UHD) or even 8K (the principle of implementation will be described later). The maximum data transmission speed can reach 10Gbps, which is also the standard of usb 3.1, Compatible with the USB 2.0 standard, it supports reverse insertion from both sides.

The most commonly used function of a type-c data cable is charging, including fast charging. Regardless of the type of data cable, there are four positive and negative poles in the power supply. The cable is thick, the pin contact area is large, and the allowable current is also large. The maximum current allowed for the type-c data cable at 5V is 3A, while the Micro USB data cable commonly used in previous Android phones was only 2A. Therefore, the type-c data cable has a fast charging speed.

The Type-A, Type-B, mini-A, mini-B, Micro-A, Micro-B interfaces in the USB 2.0 interface specification and the Type-B, Micro-B interfaces in the USB 3.0 interface specification all share a common feature of foolproof design, while the type-c interface does not distinguish between positive and negative aspects. Another major selling point of the USB 3.1 type-c is the enhancement of mobile device charging capability. The maximum allowable power supply standard under the USB 3.1 interface has been significantly increased to 20V/5A (Type-A/B only), providing up to 100W of power output capacity. The highest standard for type-c is 12V/3A 36W charging capacity.

At present, the emergence of intelligent type-c connectors coincides with manufacturers' increasing consideration of the so-called "edge computing" solution of the Industrial internet of things. In the industrial environment, edge computing refers to the trend of using localized or machine based computers to process real-time data, store data and apply analysis to find factories and workshops. In view of the growth forecast of IIot, this edge based technology has been favored recently. Some experts believe that the number of Industrial internet of things connecting devices will grow to 3 billion to 50 billion, so smart connectors provide power for the development of Industrial internet of things.

The design engineers of Guangjiayuan Science and Technology suggest that the edge computing technology can be applied to machine tools, manufacturing machinery, intelligent infrastructure, motors and other applications of the Industrial internet of things. Smart connectors can help such applications by retrieving real-time data and analyzing them when machines are running in the factory workshop.

In the current rapid development of the mobile phone market, many smartphones have the function of fast charging. It has the same ability as charging for 5 minutes and talking for 2 hours. And have you ever thought about why mobile phones charge so fast? Is it related to the data cable or the charger head? If we want to draw the truth through practice, of course, we need to use experiments to prove it. In fact, the method is very simple. When we charge mobile phones, we disconnect the charger and data cable, exchange the two, and test them again, and finally we can draw a conclusion.

After the experimental results were released, the editor was also puzzled to find that it was not a charger or a data cable. What exactly is that? It's actually a combination of them. If you want to achieve the goal of fast charging, you must have a matching charging cable and head, and the most important issue is that your phone needs to support fast charging. The charger head controls the voltage, and the data cable controls the current. Only when the two are combined can the current and voltage be perfectly controlled.
