Description

[Technical field]

[0001] The utility model relates to a tensile-resistant USB optical fiber line in a video conference system. [Background Technology]

[0002] In the current conference system, the USB copper cable used to connect the conference camera has a maximum transmission distance of no more than 5 meters without an amplifier chip, and the usable distance range is small; with a chip amplifier, the transmission distance reaches 30 meters, but the signal will gradually attenuate as the cable length increases, resulting in unstable video images or even failure to display. At the same time, the chip amplifier increases production costs. [Contents of the utility model]

[0022] Example 1 Figure 1 As shown, a tensile USB optical fiber cable in a video conference system includes an insulating sheath 1, in which a power cable 2, a ground cable 3, a data transmission cable 4, an optical fiber cable 5 and a phosphating steel wire 6 are arranged, and the power cable, the ground cable, the data transmission cable and the optical fiber cable are respectively connected to a USB connector, the data transmission cable 4 includes a shielded aluminum foil layer 41 and a D+ data transmission cable 42 and a D- data transmission cable 43 arranged in the shielded aluminum foil layer 41, and the optical fiber cable 5 includes a wire core sheath 51, a plurality of optical fiber cores 52 arranged in the wire core sheath 51 and a grease layer 53 filled in the wire core sheath 51. When in use, the USB connector is plugged into the conference camera in the conference system, and the optical fiber core 52 of the optical fiber cable 5 is used to realize the long-distance signal transmission function. Among them, the power cable 2 and the ground cable 3 realize the power supply connection; the D+ data transmission cable 42 and the D- data transmission cable 43 in the data transmission cable 4 realize the differential signal transmission function, and the shielding aluminum foil layer 41 sleeved on the outside can shield the external interference signal; the optical fiber core 52 in the optical fiber cable 5 realizes long-distance data / video signal transmission, and the core sheath 51 plays a role in protecting the optical fiber core 52, and the grease layer 53 plays a role in buffering external force, reducing the friction loss between the optical fiber cores 52 and waterproofing; the phosphating steel wire 6 is used to withstand the pulling force during the wiring process to prevent direct pulling of the optical fiber core 52.

The phosphating steel wire 6 is arranged in the middle position to mainly bear the pulling force during the wiring process and protect the various cables arranged around it.

[0025] like Figure 1-2 As shown, the diameter of the phosphating steel wire 6 is in the range of 0.3-0.4 mm, preferably 0.35 mm, which provides sufficient pulling resistance for the USB optical fiber cable and minimizes the overall volume of the USB optical fiber cable to facilitate wiring.
