If you search for Type-C connector products or manufacturers on Baidu, there are not 100 or 80. Although Type-C connectors are currently popular, the competition is also quite fierce. How to choose a matching connector manufacturer is actually a challenge for our cable component factories. Considering that cables and connectors can affect their performance due to factors such as high-frequency signals, mechanical characteristics, electrical performance, and environmental changes, Therefore, the manufacturer needs a complete set of test certification plan and the assistance and consultation of professional laboratories to ensure that the product meets the quality conditions and perfectly demonstrates the Functional requirement; The certification agency will also conduct relevant testing and verification on the testing content required for Electrical Test, Mechanical Test, and Environmental Test to ensure that the manufacturer's products can meet the standards of the association. During the process provided by the association and verified by the testing center, the manufacturer will also obtain production parameters for subsequent production and manufacturing; To ensure the reliability and sustainability of products, industry brands and system manufacturers are required to choose products that use TID authorized and certified connectors! TID certification has become the threshold for entering brand channels; Today, we will share the basic introduction of type-c connector interfaces and provide some basic functional tips for purchasing cables. Of course, you can also directly recommend reliable connector manufacturers or TID manufacturers who have conducted on-site inspections to our customer service.

Since the release of USB in 1998, it has been more than 20 years since its release. During these 20 years, the USB-IF organization has released N interface states, including A port, B port, MINI-A, MINI-B, Micro-A, Micro-B, and other interface forms. Due to the different preferences of each product, different types of sockets are used for different products, resulting in tragedy. We also need to keep N unknown interface adapter wires available. For type-c, It seems that the USB standardization organization is also aware of the issue of unification and standardization. When defining standards, in addition to defining hardware interfaces, some "personalization" features have been added. In the definition of type-c plugs, the following three types of plugs are mainly defined:

The type-c interface defines the (24 pin) standard USB 3.1 wire. The Yokkaichi Asunarou Railway Utsube Line core has 21 cores in total, 16 more cores than USB 2.0, thus meeting the high-speed transmission standard of USB 3.1 and 100W output power. Its maximum transmission rate is 10Gbits/S, maximum output power is 100W, and maximum current is 5A. Using USB 3.1, it needs to connect two sets of TX+/- and two sets of RX+/- for high-speed data transmission.

USB 3.1 is fully functional, supports type-c, supports PD protocol, supports high-speed signal, supports ultra fast charging, supports HDMI, DisplayPort and other protocols. This protocol only supports USB 3.1 GEN2 cable channels, with a transmission rate of up to 10Gbps. When applying USB 3.2 specifications, it can achieve 20Gpbs, suitable for high-speed interconnected application scenarios, such as virtual reality devices, game consoles, camera devices, and other fields.

Product category 2: type-c female head, type-c male head (a pair of D+, D -, with only one CC pin and the other CC pin becoming VCONN), generally used in Power Delivery, providing high reliability signal transmission and intelligent fast charging 100W solutions for consumer grade products, automotive electronics and other application scenarios, using high flexibility cables, miniaturized appearance design, and up to 100W intelligent fast charging design, Meet the application needs of automotive electronics and consumer grade products.

Conventional application scenarios

If you only use USB 2.0, you can directly use A6, A7, B6, and B7. A6 connects to B6 for D+, A7 connects to B7 for D -, and other data pins can be suspended.

The most common is the USB2.0 A TO C series, which is a consumer grade product widely used in thousand yuan configuration of mobile phone ports. Only type-c, which supports forward and reverse insertion, and ordinary data transmission;

The pins related to the power supply are A4 and A9; B4 and B9, also known as the power cord above the USB cable, have the four outermost pins at both ends that are the ground of the power supply

It is worth noting that the configuration pins, namely A5, B5, CC1 and 2, are used for connection discovery, configuration, and management. For plugs, there is only one CC, while for sockets, there are two: CC1 and 2.

At present, connector manufacturers are commonly selling connector types. Nowadays, the USB type-C trend is sweeping across the entire intelligent terminal, leading the convergence of interfaces. Many connector companies have seized the development opportunities well. Type-C is making significant strides in the evolution of applications such as smartphones, laptops, and automobiles, and will also become the only interface for power and data transmission between electronic devices in the next decade. After several years of development, The type-c interface will eventually unify the market. It is reported that Guangjiayuan Electronics has long recognized the development prospects of the type-c market. Therefore, they began to lay out their connectors at the beginning of the market, especially in the fully functional series of connectors. The type-c interface can insert and transmit high-speed data and audio and video signals in both forward and backward directions. It is also compatible with the PD protocol and can provide up to 100W of charging power, which is expected to replace other data in electronic devices Audio, video, and power interfaces are ultimately unified.
