If you search in Baidu, there are not 100 TYPE C connector products or manufacturers, but there are 80. Although TYPE C connectors are hot now, the competition is also quite fierce. How to choose a matching connector manufacturer is actually on the table. A difficult problem for our cable assembly factories. In view of the fact that the performance of cables and connectors will be affected by factors such as high-frequency signals, mechanical characteristics, electrical performance, and environmental changes, manufacturers need a complete set of testing and certification plans and professional experiments. The assistance and consultation of the laboratory can ensure that the product meets the quality conditions and perfectly displays the functional requirements.

Basic introduction to TYPE C connector interface

The certification body will also conduct relevant test verification on the test content required for electrical testing, mechanical testing, and environmental testing to ensure that the manufacturer's products can meet the standards of the association. Production parameters are convenient for subsequent production and manufacturing; in order to ensure the reliability and continuity of products, brand owners and system manufacturers in the industry are required to choose products using connectors with TID authorization certification! TID certification has become the threshold to enter the brand channel; today we will share the basic introduction of TYPE C connector interface, and give some basic functional skills for purchasing cables. Of course, you can also directly ask our customer service to recommend reliable ones that have been inspected on the spot. Connector manufacturers or manufacturers with TID.

Since the release of USB in 1998, USB has gone through more than 20 years. During these 20 years, the USB-IF organization released N types of interface status, including A port, B port, MINI-A, MINI-B, Micro -A, Micro-B and other interface forms, because the preferences of each product are different, different products use different types of sockets, so the tragedy is coming, we also have to keep the interface conversion cables of unknown uses in N, and for Type- For C, it seems that the USB standardization organization is also aware of the issue of unification and standardization. When defining the standard, in addition to the definition of the hardware interface, it also adds some "personalized" features. In the definition of the TYPE C plug, it mainly defines the following three Types of plugs:

The full-featured Type-C plug can be used on platforms and devices that support USB2.0, USB3.1, and other features. The USB 2.0 Type-C plug can only be used on platforms and devices that support USB2.0. USB Type-C Power-Only plug, used on devices that only need power supply (such as chargers).

The standard USB3.1 cable has 21 internal wire cores, 16 more wire cores than USB2.0, thus meeting the high-speed transmission standard of USB3.1 and 100W output power, and its maximum transmission rate is 10Gbits/S , Z maximum output power 100W, Z maximum current 5A, use USB 3.1 need to connect two sets of TX+/-, two sets of RX+/- for high-speed data transmission.

USB3.1 is full-featured, supports Type-C, supports PD protocol, supports high-speed signals, supports ultra-fast charging, supports HDMI, DisplayPort and other protocols, this protocol only supports the cable channel of USB3.1 GEN2, and its transmission rate It is as high as 10Gbps, and when the USB3.2 specification is applied, it can reach 20Gpbs, which is suitable for application scenarios suitable for high-speed interconnection, such as: virtual reality equipment, game consoles, camera equipment and other fields.

Product category 2: typec female connector, typec male connector (a pair of D+, D-, only one CC pin, the other CC pin becomes VCONN), generally in Power Delivery, for consumer products, automotive electronics and other application scenarios The products provide high-reliability signal transmission and smart fast charging 100W solutions, using high flexibility cables, miniaturized appearance design and up to 100W smart fast charging design, to meet the application requirements of automotive electronics and consumer products.

If you just use USB 2.0, you can use A6, A7, B6, and B7 directly. A6 is connected to B6 as D+, A7 is connected to B7 as D-, and other data pins can be left floating. The most common one is that the USB2.0 A TO C series is a consumer-grade product, which is widely used in thousands of yuan to configure mobile phone ports. There is only Type-C, which supports positive and negative plugging and ordinary data transmission.

The pins related to the power supply are A4, A9; B4, B9, that is, the power line on the USB cable, and the four pins outside Z at both ends are the ground of the power supply. It is worth noting that the configuration pins, that is, A5, B5, CC1 and 2, are used for connection discovery, configuration and management. For the plug, there is only one CC, and for the socket, there are two: CC1 and 2.
