OPTICAL-ELECTRICAL COMPOSITE CABLE SYSTEM

摘要

An optical-electrical composite cable system comprising an optical-electrical composite cable (4) and at least one external module. Each external module comprises a housing (3), a PCB (10), a first power drawing element, a second power drawing element, and a cable-pressing plate (2). Notches are provided at either end of the housing. The notches and the cable-pressing plate constitute a through hole for the optical-electrical composite cable to pass through. The cable-pressing plate (2) and the housing (3) form a module cavity. The PCB (10) is provided within the module cavity. An optical cable of the optical-electrical composite cable (4) is provided with an external optical fiber. An optical module is provided on the PCB (10). The optical module and the external optical fiber are connected to form an optical path. The first power drawing element and the second power drawing element are electrically connected to the PCB (10) and respectively are arranged opposite a live wire cable and an earth wire cable of the optical-electrical composite cable. The cable-pressing plate presses tight the optical-electrical composite cable to allow the first power drawing element to come into contact with a metal core of the live wire cable and the second power drawing element with a metal core of the earth wire cable, thus implementing an electrical path. The described solution solves the problem of low efficiency in connecting an external device to the optical-electrical composite cable and insufficient flexibility in setting or changing the position of the external device.
