D-SUB connectors have variations of models, options and accessories, including high and low frequency mixing, high current and high density, which is a very economic interconnect solution 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, there before, the problem of different heights of the feed caused by loose harpoon shaped plate lock and easily to twist 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 matching cycles, a new direct solvable economic series of connectors has been added, such as set top boxes, control devise and electrical meters, which are increasing in demand The D-SUB is the earliest input/output connector system solution, and it is also the most directors and widely used one
