Polarity DC power supply connector that can 8 compatible suffix plugs

The utility model discloses a polarity DC power supply connector that can 8 compatible suffix plugs, its characterized in that: including polarity DC power supply connector and two the power contact pins of setting on polarity DC power supply connector, the jack of polarity DC power supply connector is compared in the jack of 8 traditional suffix power connectors, has set the 14 circular insertion hole structure of arbitrary one corner in " 8 " the word structure four corners to square socket structure. The utility model discloses on the basis of 8 suffix sockets, the extension is to polarity power plug's compatibility, and the space occupy -place is still the same with 8 suffix sockets, does not increase, both can use conventional 8 nonpolarity suffix power plug, also can use the direct current power plug of heteropolarity, and simple structure, convenient to use, cost are lower. 本实用新型公开了种可兼容8字尾插头的极性直流电源联接器，其特征在于：包括极性直流电源联接件和设置在极性直流电源联接件上的两个电源插针，所述极性直流电源联接件的插孔相比于传统的8字尾电源联接件的插孔，将"8"字结构四角中任意角的1/4圆形插孔结构设置成了方形插孔
