Light guiding column for communication cabinet plugboard

Abstract

The invention provides a light guiding column for a communication cabinet plugboard. The light guiding column has a mechanical integral structure and furthermore is made of a polycarbonate composite material with excellent transmittance. The light guiding column comprises a plurality of light transmission units which are uniformly distributed in a linear array. Each light transmission unit comprises a cylindrical boss, a slot and a trough. The cylindrical boss comprises a thin cylinder which is used for externally connecting with a light-penetrable hole on a front panel of a communication cabinet, and a thick cylinder which performs a positioning function on the thin cylinder. The thin cylinder and the thick cylinder are coaxially arranged and form a stepped structure. The cylindrical boss performs a function of converging and transmitting light which is emitted from an LED lamp in a PCB in the communication cabinet. Each cylindrical boss is arranged coaxially with the trough at a corresponding position. The slot has a through structure. The LED lamp is embedded into the trough. The light guiding column is advantageous in that the cylindrical boss is arranged between the front panel and the PCB, and transmission channel is supplied for optical signal transmission of the LED lamp, thereby greatly improving light guiding efficiency of an optical signal which is transmitted from the LED lamp.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a light guide column for a plug-in card of a communication case. Background technique [0002] At present, in all kinds of communication chassis equipment, there are horizontal or vertical plug-in cards with different functions on the chassis, and the role of the LED indicators on the plug-in cards is particularly important, which can display the operating status of the plug-in cards or Transmission status of important signals. In the prior art, the front panel is usually installed in front of the plug-in card, and the corresponding LED lights are installed on the front panel. However, due to design reasons, the LED indicator lights on the plug-in card are far away from the front panel, or the design When printing a printed circuit board (PCB for short), the LED indicators must be kept away from the front panel, resulting in fuzzy or unclear display of the LED indicators o...

In the prior art, the front panel is usually installed in front of the plug-in card, and the corresponding LED lights are installed on the front panel. However, due to design reasons, the LED indicator lights on the plug-in card are far away from the front panel, or the design When printing a printed circuit board (PCB for short), the LED indicators must be kept away from the front panel, resulting in fuzzy or unclear display of the LED indicators on the front panel. The transmission state of the signal causes debugging difficulties
