The invention provides a perpendicular orthogonal interconnection system and a communication device, suitable for the field of the communication technology. The perpendicular orthogonal interconnection system comprises a first veneer group, a second veneer group and a middle-mounted backboard, wherein the first veneer group and the second veneer group are orthogonal, and the middle-mounted backboard is mounted between the first veneer group and the second veneer group. The first veneer group comprises multiple parallel first veneers, and the second veneer group comprises multiple parallel second veneers. Multiple bending male connectors are arranged on the first veneer, and multiple bending female connectors are arranged in the second veneer, wherein the bending male connectors are directly cooperated and connected with the bending female connectors in one-to-one correspondence. According to the inventionthe bending male connectors and the bending female connectors are directly cooperated and connected. Thus, to upgrade the perpendicular orthogonal interconnection system only requires replacing veneers which are equipped with the bending male connectors and the bending female connectors, which is quite simple and shortens signal links. Based on the above advantages, the perpendicular orthogonal interconnection system can be used in various communication devices, thereby making upgrades convenient, improving signal qualities, being good in heat radiation and saving material costs.
