US Patent 7909652 Electrical connector with two grooves dividing contacts

An electrical connector (2, 3) provides an interface compatible with an internal micro Serial ATA connector. The electrical connector (2, 3) includes an insulated housing (21, 31), a first number of contacts (221, 222, 223, 321, 322, 323) assembled to the insulated housing (21, 31); and a second number of contacts (224, 225, 324, 325) assembled to the insulated housing (21, 31). The first number of contacts (221, 222, 223, 321, 322, 323) constitute a power segment and a signal segment compatible with the internal micro Serial ATA connector. The second number of contacts (224, 225, 324, 325) is used for mating with a new type of mating connector (3, 2) when higher transfer speed is needed.
