4-channel fiber optic guide for photoelectric composite cables {4 CHANNEL OPTICAL FIBER GUIDE FOR HYBRID MULTIMEDIA CABLE}

The present invention relates to a four-channel optical fiber guide for a photoelectric composite cable, and more particularly, to facilitate the connection operation of the optical fiber of the photoelectric composite cable, the alignment of the optical fiber is maintained firmly, as well as having a strong durability against external loads A four channel optical fiber guide for a composite cable.

Recently, as the interface standard that can integrate and transmit uncompressed digital video and audio signals, the spread of equipment of HDMI (High Definition Multimedia Interface) interface standard is increasing. It integrates audio signals for home use, and does not require a decoder chip or software because the video and audio signals are transmitted from a signal providing device to a video device such as a TV without being compressed.

This is a standard that replaces an existing analog terminal and is being applied to a PC, a DVD player, or an HDTV. The multimedia device that receives the integrated signal from the multimedia device providing the integrated video and audio signal and outputs the video signal and the audio signal may be connected through an HDMI standard dedicated cable and connector.

Conventionally, the cable used for the HDMI standard generally used is a conductor such as copper, but when the length of the cable is long, the signal loss is large, it is impossible to implement high quality and high sound quality by the uncompressed digital video and audio signals.

Recently, multimedia output devices (projectors, large screens or the like) that receive video signals and audio signals by receiving the integrated signals from multimedia signal devices providing integrated video and audio signals, such as large stadiums, lecture halls and auditoriums, as well as homes. The problem is even greater if the distance to the loudspeaker) is several tens or hundreds of meters or more.

Therefore, as a cable for HDMI standards introduced recently, Korean Patent Publication No. 10-2016-0023524 (Multimedia Photoelectric Composite Cable), Korean Patent Publication No. 10-2016-0041478 (Photoelectric Composite Cable), Korean Patent Publication No. 10 As disclosed in -20150078265 (Photoelectric Composite Cable) and the like, various types of photoelectric composite cables for multimedia have been developed and used.

The photoelectric composite cable may be composed of an optical unit including an optical fiber and a conductor unit including a conductor. A video signal or an audio signal is transmitted through the optical fiber constituting the photoelectric composite cable, and a power or control signal is transmitted through the conductor. Etc. can be provided.

The multimedia photoelectric cable includes a cable of a plastic optical fiber (POF) method and a cable of a glass optical fiber (GOF) method according to the type of optical fiber. GOF type cable has a disadvantage in that it can not maintain the banding characteristics due to a sudden change in the outside, POF type cable has a limitation that can be transmitted only a very short distance because the optical loss is so large that it is urgent solution to this situation.

In the process of integrating the photoelectric cable, the optical connector may need to be immediately connected with the optical cable of the optical unit of the photoelectric composite cable. This work should be done to precisely insert the optical fiber into the ferrule or the connecting tube, which may cause the optical fiber to be damaged, and to maintain the alignment of the optical fiber after the connection.
