The type-c3.1 male head has 16 solder joints and comes with an E-Marker chip. It can not only support 20V 5A 100W fast charging under the USB PD3.0 fast charging protocol, but also meet the high-speed transmission of USB3.2Gen2x220Gbps, suitable for lightning or USB4 data cable design.

In terms of workmanship, the shell of the type-c3.1 male head adopts spot welding treatment to prevent instantaneous breakage and shell falling; The terminal adopts 7025 high conductivity copper, with a minimum of 3U gold plating, and the theoretical maximum current can exceed 8A; At the same time, it has also passed the USB-IF association certification. In addition, the terminal spring height meets the association size, and the high-frequency differential impedance meets the association standard. It is mainly used for charging and can support voltage specifications such as 28V, 36V, 48V, etc. In terms of materials and workmanship, the shell is spot welded to prevent instantaneous breakage and shell falling, meeting various structural needs of customers. The PIN pin size is fully CCD detected to avoid skewed pins, electrical testing is used for shipment, and glue wrapping and short circuits are avoided.

Type-c14p encapsulated PCBs are as follows:

First pin: GND power negative input terminal

Second pin: VDD power positive input terminal

Third pin: D-data voltage input terminal

Fourth pin: D+data voltage input terminal

Fifth leg: CC2 configuration channel

Sixth pin: VDD power positive input terminal

Seventh pin: GND power negative input terminal

Eighth pin: GND power negative input terminal

Pin 9: VDD power positive input terminal

Pin 10: D-data voltage input terminal

Pin 11: D+data voltage input terminal

Step 12: CC1 configuration channel

Thirteenth pin: VDD power positive input terminal

Pin 14: GND power negative input terminal

From the above figure, it can be seen that the Pin feet are symmetrical relative to the center. The male head is inserted into the female head, and the pin functions perfectly match regardless of whether it is inserted forward or backward. Moreover, the power supply VBUS/GND both have 4 pins, supporting a maximum current of 5A, ensuring high-speed data transmission while also improving current carrying capacity.

Pin definition:

In addition to the pins used in USB2.0 and USB3.0, there are also some other pins mentioned above. Let's briefly introduce them.

CC (Configuration Channel): Configure channel signals for connection discovery, configuration, and management.

SBU (Side Band Use): Sideband use signals are suitable for transmitting non USB signals, such as audio signals.

USB-PD (USB Power Delivery) is a USB charging standard and technology launched by the USB standardization organization USB-IF. In 2017, USB-IF added Programmable Power Supply (PPS) to USB-PD 3.0. PPS, as a major upgrade to PD 3.0, aims to provide a unified specification for fast charging solutions.

USB PD Features:

Raise the existing USB standard to a power level of 240W.

The direction of the power supply is no longer fixed, which allows products with a power supply (host or slave) to provide electricity to other devices.

Optimize power management across multiple peripheral devices. Allow each device to only use the power it needs and provide more power to specified applications when needed.
