The invention provides a cable backboard which comprises a PCB backboard and at least one cable connector. The cable connector comprises a housing; and a first pin and a second pin arranged on the housing. The first pin is used for connecting a cable. The PCB backboard is provided with a crimping through hole used for cooperating with the second pin to make the housing fixed on the PCB backboard; and a penetrating area used for exposing the first pin. By making the second pin arranged on the cable connector and the crimping through hole arranged on the PCB backboard mutually clamped, the cable backboard makes the cable connector directly bonded and fixed on the PCB backboard. Extra adapting connectors and box type complex structural members are no longer required. The space of a sub-rack is saved. Furthermore, the cable backboard with a simple structure ensures any flexible point-to-point connection of the cable.
