JCDW37 Series Prinetd Circuit Board Connectors

This product is a high-density, high-reliability micro-miniature electrical connector designed for demanding applications. The connector features a precise centerline spacing (pitch) of 1.3mm between contacts, enabling a compact footprint. The core of its contact system utilizes a unique 0.65mm "Twisted-Pin" (or "Helical Pin") design. These specially shaped pins provide superior electrical and mechanical performance. Contacts are terminated via crimping onto flexible wire leads, offering a robust and reliable solderless connection. The insulator is molded from thermosetting plastic, ensuring dimensional stability, high-temperature resistance, and long-term resistance to aging. The product is manufactured in full compliance with the enterprise military standard ZZR-Q/RJH21002A, guaranteeing consistent quality and performance.

    Features and Advantages

    1. The defining feature is the innovative 0.65mm Twisted-Pin contact.

    2. This design offers significant advantages:

    3. Tt creates multiple, redundant contact points for lower and more stable contact resistance, and its inherent springiness ensures excellent vibration resistance and long-term mating cycle durability.

    4. The 1.3mm pitch allows for miniaturization and high contact density in space-constrained designs.

    5. The crimp termination provides a gas-tight, reliable connection that is ideal for flexible cables and resists failure from mechanical stress.

    6. The thermosetting plastic insulator is a critical feature, providing the advantages of exceptional thermal stability (withstanding high soldering and operational temperatures), excellent dielectric properties, and resistance to environmental aging, which ensures long-term insulation integrity.

    Application

    These connectors are ideally suited for miniaturized electronic systems where space, weight, and reliability are paramount. Key application areas include:

    1. Aerospace and Avionics: Onboard flight control systems, navigation equipment, and sensor interfaces.

    2. Military Electronics: Portable communication devices, guidance systems, and field-deployable instrumentation.

    3. High-Reliability Industrial Equipment: Medical devices, robotics, precision test and measurement apparatus, and down-hole instrumentation.

    4. Telecommunications: High-density board-to-board or wire-to-board interconnections in compact networking hardware.

    5. Their compliance with a stringent military-derived standard makes them a trusted choice for critical interconnections in harsh operating environments.
