Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire harness technology, specifically, it relates to a high-bandwidth communication wire harness. Background Technology
[0002] Existing wire harnesses typically contain power lines, signal lines, video lines, network lines, etc. These lines are integrated together, resulting in a thicker wire harness diameter. They are also susceptible to external interference, and the transmission rate is generally low. When wire harnesses are used in products such as intelligent driving vehicles, the transmission of large amounts of LiDAR signals or vision camera signals in the vehicle will be limited by the transmission and anti-interference performance of the wire harness. Fiber optic cables can improve transmission efficiency and anti-interference performance, but the tensile and bending resistance of fiber optic cores is poor and they are easily damaged during installation. In order to improve the tensile and bending resistance of fiber optic cables, a high-bandwidth communication wire harness is provided. Utility Model Content

The optical fiber ribbon passing part has a reinforcing strip passing hole and an optical fiber ribbon passing hole. Grooves 1, 2, and 3 are provided on the two flat surfaces of the sheath. Groove 1 is located on the two flat surfaces between the steel wire passing part and the optical fiber ribbon passing part, groove 2 is located on the two flat surfaces at the optical fiber ribbon passing hole, and groove 3 is located on the two flat surfaces between the optical fiber ribbon passing part and the power line passing part. The optical fiber ribbon has multiple optical fiber cores arranged in a strip shape. A loose tube is sleeved on the outside of the optical fiber core, and fiber grease is filled between the loose tube and the optical fiber core.

[0018] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0019] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the cross-section of a wire harness according to one embodiment of the present invention; Figure 2 This is a schematic diagram of the optical fiber strip in one embodiment of the present invention.
[0020] A high-bandwidth communication cable harness includes: a sheath 1; an optical fiber ribbon 2 passing through the sheath 1; the sheath 1 is a flat strip, and the sheath 1 has a steel wire passing part 3, an optical fiber ribbon passing part 4, and a power line passing part 5. The optical fiber ribbon passing part 4 has a reinforcing strip passing hole 6 and an optical fiber ribbon passing hole 7. Grooves 1-8, 2-9, and 3-10 are provided on the flat surfaces on both sides of the sheath 1. Groove 1-8 is located on the flat surfaces on both sides between the steel wire passing part 3 and the optical fiber ribbon passing part 4. Groove 2-9 is located on the flat surfaces on both sides at the optical fiber ribbon passing hole 7. Groove 3-10 is located on the flat surfaces on both sides between the optical fiber ribbon passing part 4 and the power line passing part 5. The optical fiber ribbon 2 has multiple optical fiber cores 11, which are arranged in a strip shape. Loose tubes 12 are sleeved on the outside of the optical fiber cores 11. Fiber grease is filled between the loose tubes 12 and the optical fiber cores 11. An outer sheath 13 is sleeved on the outside of the loose tubes 12.
[0021] The cross-section of the wire threading section 3 is circular; the bottom of the first groove 8 is flat; the cross-sections of the second groove 9 and the third groove 10 are "V" shaped; the reinforcing strip 14 is threaded through the reinforcing strip threading hole 6, and the reinforcing strip 14 is made of fiber composite material; the cross-section of the outer sheath 13 is circular, and a flat hole is provided in the middle, and the flat extension of the hole is the same as the flat extension of the sheath 1; the power line threading section 5 is for threading the power line.
[0022] Grooves 1 (8), 2 (9), and 3 (10) can be quickly cut by shortening the grooves to cut the steel wire threading section 3, the optical fiber threading section 4, and the power line threading section 5 when the wire harness is damaged and recycled. This facilitates sorting and recycling, and also reduces the weight of the wire harness and improves heat dissipation.
[0023] The steel wire 15 is threaded through the steel wire threading part 3 to improve the tensile strength of the wire bundle. The reinforcing strips 14 set on both sides of the optical fiber strip 2 can further improve the tensile strength and bending strength. The flat hole in the outer sheath 13 makes the two sides of the hole have a relatively thick protective layer, which can effectively improve the bending strength.
[0024] This utility model uses an optical fiber strip 2, in which the optical fiber cores each transmit signals, video and other data. The sheath 1 separates the optical fiber strip insertion part 4 and the power line insertion part 5 through grooves. The main purpose is to set a reinforcing structure for the optical fiber strip 2 to improve its tensile and bending resistance.
