What should I pay attention to when designing USB Type-C?

Today's USB type-c standard has gradually become the mainstream of USB connector interface. The production design and development of smarter connectors, plug interfaces and USB cables are the issues and development directions that connector manufacturers need to pay attention to. USB type-c The range of applications that the standard can provide is also increasing, and the rules of this series are continuing to evolve. Such a solution can be connected without separate power adapter data and power transmission, and is widely used in portable devices, data centers, infotainment systems, and outdoor LED display devices. Therefore, engineers need to pay attention to three key design points when designing USB Type-C connectors.

power supply

It is critical that the USB Type-C connector cable sends and receives the right amount of power and requires the correct components. A suitable resistor and a system for leveling power will ensure that the cable consumes only the same amount as the host device. Electrical energy.

Multi-function signal transmission

The USB Type-C standard also requires cables to use precise wire sizes and the correct connector construction. Proper signal integrity, as well as protection against RF and electromagnetic interference, allow the multifunction signal to work effectively. Vendors with some USB Type-C connector solutions can provide a shield design on the back of the socket housing to help eliminate unwanted electromagnetic interference (EMI) leakage.

Sturdy structure

Enhanced retention and splash-proof options should be provided during product design to ensure that USB Type-C connectors can operate in harsh industrial environments, which requires enhanced environmental sealing and mechanical strength. For beginners, the IEC-60529-IP67 specification ensures a joint seal to prevent ingress of dust and is protected by high pressure water jets. It also supports immersion in water for a limited time.

On the other hand, the rugged construction of the USB Type-C connector can be done with upgraded materials such as gold-plated and nickel-plated contacts to prevent corrosion. Design features such as conductive silicone rubber gaskets and threaded panel connection points also allow the connector to operate in extreme environments, and the USB Type-C connector also features through-hole mounting for a mechanically robust PCB connection.
