IEC Screw Mount Male Connector with Plastic Spring Cover

The CONNECTOR [IEC SCREW MOUNT MALE WITH SPRING] is a panel-mount AC input plug engineered for electric scooters, e-bikes, off-board battery chargers, and power conversion equipment. Designed as a standardized male C14-style IEC inlet, this connector forms the primary power interface between external mains AC cords and onboard battery charging systems.

Constructed from a flame-retardant thermoplastic outer shell and nickel-plated copper alloy pin terminals, this inlet is equipped with double screw-mount flanges and internal spring-retention tabs. This dual-securing mechanism absorbs severe vehicle vibration, prevents plug loosening, and protects internal connections from thermal degradation during prolonged charging cycles across 12V to 60V DC battery sub-circuits and up to 250V AC input lines.

Key Features

• Dual Screw-Mount & Spring Retention: Features screw-fastened flanges combined with spring-loaded housing tabs to lock the inlet firmly into vehicle body panels without loose play.
• Standardized C14 IEC Form Factor: Mates universally with standard C13 female coupler AC power cables and EV charging cords.
• High-Conductivity Nickel-Plated Terminals: Heavy-duty copper alloy pin contacts ensure minimal contact resistance and reduce heat buildup under continuous electrical load.
• Flame-Retardant ABS/Nylon Housing: Thermal-resistant plastic casing protects internal connections against ambient heat and vibration fatigue.
• Solder & Crimp Spade Lug Terminals: Rear male spade terminals accept direct wire soldering or standard female quick-disconnect crimp connectors for fast assembly.

Suitable Vehicle Types & Applications

Electric Scooters & E-Bikes: Standardized AC charge inlet module mounted on outer fairings or under-seat storage compartments.

Off-Board Chargers & Power Inverters: Power input port replacement for portable EV battery charging bricks and DC power converters.

Custom EV Builds & Electronic Enclosures: Industrial AC power input connector for custom battery enclosures and diagnostic benches.

System & Electrical Compatibility

Universal Power Lines: Compatible with 12V to 60V DC auxiliary power loops as well as standard 110V–240V AC utility power inputs.

Standard IEC C13 Cord Sets: Fits all standard C13 female socket extension cables and EV charger input wires.

1. Isolate Power & Cut Panel Opening:

Turn off the key ignition, trip the main DC circuit breaker, and unplug all power leads. Prepare a standard rectangular panel cutout matching the C14 socket body with side screw holes on the vehicle frame or charger housing.

Verification: Verify with a multimeter that zero voltage is present across the target connection wires.

2. Mount IEC Connector to Frame:

Push the connector into the panel opening until the spring-retention tabs snap against the inner edge, then secure the mounting flanges using two panel screws and lock nuts.

Verification: The connector sits flat against the panel face with zero wobble or flex when pressed.

3. Wire Rear Spade Terminals:

Attach insulated copper wiring leads to the rear male spade terminals (Line, Neutral, Ground) using pre-crimped female spade connectors or perform a full solder joint covered with heat-shrink tubing.

Verification: All terminal connections are tightly seated, with no uninsulated wire strands exposed beyond the boot sleeve.

4. Reconnect Power & Test Charge Loop:

Reconnect the main battery leads, reset the circuit breaker, and plug a standard C13 AC power cord into the connector to begin charging.

Verification: Power transfers continuously through the inlet with zero flickering, rattling, or localized heating at the terminal pins.

Power Isolation: Always trip the main circuit breaker and unplug the AC power cable before servicing or cleaning socket terminals.

Contact Inspection: Regularly inspect the male nickel-plated pins for dust, carbon buildup, or surface oxidation; clean using an electrical contact cleaner spray.

Screw Tightness Check: Periodically check panel mounting screws to ensure road vibration has not loosened the housing or ground wire connections.
