AC Socket Connectors play a critical role in electronic devices, industrial systems, and power supply units by providing a safe and stable interface for AC power input. As industries such as automation, data centers, medical electronics, and smart appliances continue to grow, the demand for high-quality AC socket connectors has increased significantly. A well-designed power inlet connector directly affects product reliability, safety compliance, and long-term performance.
What Are AC Socket Connectors?
An AC socket connector is a component designed to receive alternating current (AC) from the mains and deliver it safely into electronic equipment. These connectors are commonly mounted on panels or PCBs and comply with international standards such as IEC 60320.
Common types include:
-
IEC 60320 inlets (C6, C8, C14, C20, etc.)
-
Panel mount AC sockets
-
PCB mount AC sockets
-
Wire-to-board and wire-to-wire configurations
They are engineered to handle high voltage, high current, and frequent plug-in cycles while maintaining excellent electrical insulation and mechanical strength.
Key Technical Specifications and Selection Factors
-
Rated Voltage and Current
Typical ratings include 125V or 250V AC, with current ranges from 2.5A to over 20A depending on application requirements. -
Safety Certifications
Professional AC socket connectors usually carry international approvals such as:
-
UL (USA)
-
VDE / TUV (Germany)
-
ENEC (Europe)
-
CCC (China)
