D-SUB connectors come in various models, options, and accessories, making them a very cost-effective interconnect solution. Including high and low frequency mixing, high current, and high-density models. His components include an insulating body, a harpoon shaped plate lock, a back cover, and multiple conductive terminals; After assembly, the harpoon shaped plate lock is limited within the limit mechanism, effectively solving the problem of uneven foot height caused by unreliable positioning and easy rotation of the existing D-SUB connectors.

The D-SUB connector, as a standard connector, has a wide range of applications. Moreover, new circuit board direct soldering economic series connectors have been added, catering to the growing demand for applications that only require fewer plug and unplug times, such as set-top boxes, control devices, and meters. The demand for these economic series applications is increasing. The D-SUB connector is one of the earliest input/output connector system solutions, and it is also the most widely used and versatile one.
