  • 1. Features of D-SUB connector

    1. Easy plugging and unplugging: The D-SUB connector adopts a push-pull plug-in design, which is convenient and fast, and can quickly connect and disconnect the circuit.
    2. Reliable contact: The contact of the D-SUB connector is made of high-quality metal material, which is precisely processed and gold-plated, and has good conductivity and long service life.
    3. Wear resistance: The contact of D-SUB connector is made of wear-resistant material, which can withstand frequent plugging and unplugging and long-term use, and is not easy to be damaged.
    4. Multiple specifications: D-SUB connectors have multiple specifications, suitable for different cables and sockets, and the appropriate specifications can be selected according to actual needs.
    5. High reliability: The design of D-SUB connectors focuses on reliability. After strict quality control and testing, it can ensure that there will be no problems such as poor contact or short circuit during use.

  • 2. Classification of D-SUB connectors

    ‌Solder cup D-Sub connector‌: This connector meets commercial industrial standards and can be paired with any docking solder cup D-Sub connector. The contacts are electroplated with flash gold, and the connector insulator meets the UL94V-0 standard. The maximum wire size is 20 AWG, and 9, 25, 37 and 50 pin specifications are available.

    ‌Crimp D-Sub connector‌: Crimp D-Sub connectors meet commercial industrial standards and can be used for most standard D-Sub male connectors. Compatible with 20-28 AWG wire range, available in 9, 15, 25 and 50 pin sizes.

    ‌Punch-type D-Sub connector‌: This connector is easily soldered into the through-hole of the printed circuit board or used in many other applications. Solder placement follows a standard footprint, and gold-plated contacts ensure long life. As an industrial standard commercial DB37 female PCB type connector, it has standard mounting holes for application flexibility.

  • 3. Problems caused by poor contact of D-SUB connectors

    Performance: increased contact resistance, circuit breakage, contact curtain movement, etc.

    Causes: inadequate connection, insufficient contact area, dirt, corrosion, oxidation, etc.
    Solution: Re-plug the connector, clean the connection part (use alcohol or other cleaning agents), replace the contact or connector.

  • 4. FAQ of D-SUB Connector

    ‌D-SUB connector connection is poor

    Performance: shell damage, bayonet connector loose or stuck after plugging.
    Cause: internal defects of the connector, external force damage.
    Solution: Check and repair internal defects of the connector and avoid external force damage.

    ‌D-SUB connector oxidation What are the manifestations?

    Performance: increased contact resistance.
    Cause: environmental factors and current effects.
    Solution: Clean and maintain the connector regularly, and use a protective cover to avoid pin exposure.
