D-SUB connectors have various of models, options and accessories, including high and low frequency mixing, high current and high density, which is a very economical interconnect solutions. The D-SUB connector is made of insulating body, harpoon-shaped plate lock, a back cover and a multiple conductive terminals, after assembly, the harpoon-shaped plate lock is fixed in the limit position, therefore, the problem of different height of the feet caused by loose harpoon-shaped plate lock and easily to twirl around is avoided.

D-SUB connectors are standard connectors and have a wide range of applications. For the growing number of applications that require fewer mating cycles, a new direst-solderable economical series of connectors has been added, such as set-top boxes, control devise and electricity meters, which are increasing in demand. The D-SUB is the earliest input/output connector system solution, and it is also the most divers and widely used one.
