Description

[Technical field]

[0001] The utility model relates to a flat USB optical fiber cable. [Background Technology]

[0002] With the popularity of video conferencing systems in life and production, users have higher and higher requirements for the clarity of conference videos. In existing video conferencing systems, USB copper cables are generally used to transmit data, but the maximum transmission distance of conventional copper cables does not exceed 5 meters, and the resolution can only reach 1920*1080P@30Hz, which cannot meet the user's requirements for video clarity. At the same time, the outer diameter of the cable round wire is as large as 9.0mm. When the cable length needs to be increased, the signal loss must be reduced by increasing the diameter of the copper conductor. Therefore, when the length and bandwidth are increased, the outer diameter of the cable will be larger, which cannot meet the requirements of wiring and pipe in PVC cable troughs in indoor venues. There are also technical problems such as inconvenient use. In addition, the USB copper cables on the market currently have poor anti-static and electromagnetic interference capabilities.

[Drawings]

[0016] Figure 1 It is a schematic diagram of the structure of the utility model. [Specific implementation method]

[0017] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.

[0018] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one of the features.

[0019] like Figure 1 As shown, a flat USB optical fiber cable includes a flat insulating sheath 1, in which a power cable 2, a data transmission cable 3, an optical fiber cable 4 and a ground cable 5 are arranged from left to right, and the power cable 2, the data transmission cable 3, the optical fiber cable 4 and the ground cable 5 are respectively connected to the USB connector; the data transmission cable 3 includes a shielded aluminum foil layer 31 and a grounding ground wire 32 connected to the shielded aluminum foil layer 31, and a D+ data transmission cable 33 and a D- data transmission cable 34 are arranged in the shielded aluminum foil layer 31, and the optical fiber cable 4 includes a wire core sheath 41, a plurality of optical fiber cores 42 arranged in the wire core sheath 41, and a grease layer 43 filled in the wire core sheath 41. In actual use, the flat USB optical fiber cable is mainly used indoors. When in use, the USB connector is plugged into the conference camera in the conference system, and the long-distance high-definition signal transmission function is realized through the optical fiber core 42 of the optical fiber cable 4. Among them, the flat USB optical fiber cable is convenient for wiring and pipe running in the square PVC cable trough; the cables are arranged from left to right to facilitate cable distinction and subsequent wiring; the data transmission cable 3 includes a shielded aluminum foil layer 31 and a grounding wire 32 connected to the shielded aluminum foil layer, which greatly improves the anti-static and anti-electromagnetic interference capabilities, and can realize open wire wiring indoors, which is convenient for subsequent maintenance; the power cable 2 and the ground cable 5 realize the power supply connection; the D+ data transmission cable 33 and the D- data transmission cable 34 in the data transmission cable 3 realize the differential signal transmission function; the core sheath 41 in the optical fiber cable 4 protects the optical fiber core 42, and the grease layer 43 buffers external forces, reduces the friction loss between the optical fiber cores 42, and has a waterproof effect.

[0020] like Figure 1 As shown, the grounding wire 32 is arranged inside the shielding aluminum foil layer 31 to protect the grounding wire 32 . At the same time, it can reduce the collision of other cables with the grounding wire 32 during the wiring process to avoid it from being separated from the shielding aluminum foil layer 31 .

[0021] like Figure 1 As shown, the left and right sides of the flat insulating sheath 1 are arc structures, which are convenient for wiring and conduit threading; the distance L1 between the upper and lower sides of the flat insulating sheath 1 and the power cable 2 is in the range of 11-13mm; the distance L2 between the left side of the flat insulating sheath 1 and the power cable 2 and between the right side of the flat insulating sheath 1 and the ground cable 5 is in the range of 16-18mm. The above parameters can be changed according to different application scenarios and different PVC conduit sizes. At the same time, the flat structure is convenient for external fixation during indoor open wiring.

[0022] like Figure 1As shown, the centers of the power cable 2, the data transmission cable 3, the optical cable 4, and the ground cable 5 are on the same straight line, so that the distances between the upper and lower sides of the flat insulating sheath 1 and each cable are roughly the same, thereby better protecting each cable.

[0023] In this case, the optical fiber core 42 is an OM3 multimode optical fiber, which effectively ensures the signal integrity of long-distance transmission; the flat insulating sheath 1 is a polyvinyl chloride sheath; the power cable 2 is a red-skinned cable, and the ground cable 5 is a black-skinned cable, which is easy to distinguish between the power cable and the ground cable after connection; the D+ data transmission cable 33 is a white-skinned cable, and the D- data transmission cable 34 is a green-skinned cable, which is easy to distinguish after connection.

[0024] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
