Waterproof DC POWER JACK

1. What exactly is a DC Power Jack?

• A DC Power Jack is an electrical connector designed to receive the DC (Direct Current) power plug from a power supply unit (like an AC adapter or transformer). It is typically mounted on the circuit board or chassis of electronic devices (such as laptops, chargers, small appliances, medical equipment) and serves as the device's primary power input port. JKCR supplies DC Power Jacks renowned for their high durability and precise power delivery.

2. What are the most critical specifications when selecting a DC Power Jack?

• Choosing the right DC Power Jack is crucial. You need to pay attention to the following key parameters:

  • Center Pin Diameter: This must perfectly match your power plug (e.g., common sizes like 2.5mm or 2.1mm).

  • Outer Diameter: The external size of the connector housing.

  • Rated Voltage/Current: The maximum voltage and current the connector can safely handle. JKCR products offer various current ratings to ensure ample safety margin for your application.

  • Mounting Type: Whether it is SMT (Surface Mount), DIP (Through-Hole), or Cable Mount.

3. What unique advantages do JKCR DC Power Jacks offer?

• JKCR specializes in delivering high-quality, high-reliability power connection solutions. The core advantages of our DC Power Jacks include:

  • High Mating Cycles (Long Life): Designed with premium copper alloys and precision structures, ensuring a stable connection even after frequent plugging and unplugging.

  • Low Contact Resistance: Minimizes heat generation and power loss, improving the energy efficiency of the device.

  • Versatile Options: We offer multiple configurations, including waterproof, dust-proof, and versions with or without an internal switch (Switching type), to meet demanding industrial and medical application needs.

  • International Compliance: All products meet relevant environmental and safety certifications.

4. How does the DC Power Jack ensure stable and safe power connection?

• Stability and safety are paramount for power connectors.

  • Stability: JKCR's DC Jacks feature resilient contact points designed to ensure a tight fit when the plug is inserted, providing consistent and stable current transmission.

  • Safety: Many of our models incorporate reverse polarity protection for the center pin or internal short-circuit prevention mechanisms (e.g., the switching type can disconnect internal circuitry when the plug is removed), effectively preventing equipment damage caused by operating errors or external environment changes.

5. What is the difference between a DC Power Jack and an AC Power Inlet?

• These are two fundamentally different types of power connectors:

  • DC Power Jack: Exclusively used to receive Direct Current (DC), typically low voltage, for the second stage power input of a device (after the transformer).

  • AC Power Inlet: Used to receive Alternating Current (AC), typically high voltage from the mains, for the first stage power input of a device, like the three-prong power socket on the back of a desktop computer.

  • JKCR holds expertise in both connector fields, but our DC Power Jack series is specifically focused on the precise power transmission needs of sophisticated electronic equipment.
