Abstract: A connector for the network device comprises a connecting body and a plurality of pins. The connecting body comprises a first side and a second side, and the pins comprise a first row of pins and a second row of pins, wherein the first row of pins are provided with the first side, and the second row of pins are provided with the second side, and further, both of which comprise a plurality of negative pins and positive pins, wherein the negative pins and positive pins are spread within the first row of pins and the second row of pins alternately and evenly. Each of negative pins and adjacent positive pins are combined to be a connecting port in turn with horizontal symmetry type, such that the interference between the connecting ports can be restrained efficiently, thereby, the transmission efficiency for the network device will be improved accordingly.
