Optical fiber cable lead-in structure

摘要

An optical fiber cable lead-in structure for a shelf (1) having a space (7) for receiving a remaining portion of the optical fiber cable (23), and an electronic circuit unit (12) mounted thereon having a board (14) and a surface plate (15) provided perpendicularly at one side of the board (14); the surface plate (15) covering the front side of the shelf (1) when mounting, comprising: an optical connection (21;25) for connection between the optical fiber cable (23) and the electronic circuit unit (12), which is provided on the board (14) adjacent to the backside of the surface plate (15); an outwardly protruding portion (33) that is provided in the surface plate (15) so as to correspond to the optical connection (21;25), such that an attaching and detaching operation of the optical connection (21;25) may be easily effected; and an opening (27) that is provided in the surface plate (15) such that the optical fiber cable (23) extending from the remaining fiber cable receiving space (7) is wired so as to extend along the surface plate (15) until it passes through the opening (27) of the surface plate (15) while describing a slight arch, and in turn to extend along the backside of the surface plate (15) while describing another slight arch until it reaches the optical connection (21;25) on the board (14) of the electronic circuit unit (12).
