Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, in particular to a wire harness for unmanned aerial vehicle monitoring. Background Art

[0002] Drones are high-tech products of the information age that integrate sensor technology, communication technology, information processing technology, intelligent control technology, and aviation propulsion technology. There is a great demand for drones in industries such as surveying and mapping, remote sensing, environmental protection, mineral and energy exploration, ocean monitoring, land surveys, forest fire monitoring, public safety, national defense, and emergency rescue.

[0003] The key points of UAV technology are: power, navigation, obstacle avoidance, operation, and communication. If you want to increase the endurance time, it is inevitable to improve the energy storage and energy-saving capabilities. Therefore, small size and light weight are also one of the development directions of UAVs. During use, UAVs need to face various environments, such as high temperature, magnetic field, obstacles, electromagnetic interference, etc., so their sensitive and reliable performance is particularly important. Therefore, the UAV wiring harness is small in size, light in weight, anti-interference, good in performance, and high in reliability, which is its inevitable development direction.

[0004] A Chinese patent with patent number CN202120630886.3 discloses an ultra-fine coaxial cable harness for high electromagnetic shielding performance monitoring equipment. The wire core adopts the wire core of an ultra-fine coaxial cable harness, which has low strength and general load capacity. It is not suitable for occasions with higher loads. The main seat and shielding cover of the connector are provided with a snap-on connection. The fixed seat and shielding cover of the connector are matched through the extension plate jack. The bonding strength between the connector and the shielding cover is low. In the past, the wire harness was welded one by one to the terminal interface inside the connector, which made it difficult to ensure welding consistency and had low welding efficiency.

[0005] The aging and wear of wires in the moving parts of the drone are more serious than those in the static parts, and the parts with higher loads require higher reliability. Therefore, the wire strength of these moving parts or key parts should be higher. The outer diameter of the ultra-thin coaxial cable is about 0.3mm, while the diameter of the metal core wire inside is only about 0.025mm, which has low strength and is easily damaged.

[0006] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a wiring harness for drone monitoring. Utility Model Content

[0007] The main technical problem solved by the utility model is to provide a wiring harness for UAV monitoring, which enhances the strength of wires in key parts of the UAV wiring harness by replacing part of the extremely fine coaxial wires with Teflon electronic wires, thereby improving the transmission rate, reliability and service life of the UAV.

[0008] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a wiring harness for drone monitoring, which includes a plurality of wiring harnesses, a conductive cloth tape spirally wrapped around the plurality of wiring harnesses, connectors arranged at both ends of each wiring harness and welded and fixedly connected thereto, a shielding shell snapped on the connector, and UV glue encapsulated in the connector outlet, the wiring harness is composed of a plurality of extremely fine coaxial lines and electronic wires, the connector and the shielding shell are locked, a card slot is reserved in the connector, and welding plates opposite to each other are installed in the card slot, and the ends of the plurality of wiring harnesses are welded between the two welding plates.

[0009] Preferably, the ultra-fine coaxial line is a 42AWG silver-plated copper alloy wire, and the electronic wire is a 36AWG Teflon wire.

[0010] Preferably, the connector includes a main seat, fixing seats arranged at both ends of the main seat, a mounting groove with a lateral notch arranged on the top of the main seat body, and support openings arranged in the mounting groove at equal distances along its length direction.

[0011] Preferably, the shielding shell includes an angle plate for matching and covering the mounting slot, extension plates arranged at both ends of the angle plate, and spring sheets and plug-ins arranged at the bottom of the extension plate and perpendicular to each other, the fixing seat is provided with a first socket matching with the spring sheet and a second socket matching with the plug-in, the inner wall of the first socket is provided with an undercut that can clamp the spring sheet, one of the plug-ins is provided with an extension portion extending horizontally outward at the bottom, and the second socket is provided with an extension hole matching therewith.

[0012] Preferably, the welding sheet is bent to form a plurality of grooves for placing the wiring harness, and the shielding layer of the wiring harness is welded to the welding sheet.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The wiring harness is composed of several ultra-fine coaxial lines and electronic wires. The electronic wires have high strength and load capacity. The key parts of the drone wiring harness are enhanced to make it have higher strength, better load capacity, and higher transmission rate. Although the electronic wire is heavier than the ultra-fine coaxial line, the impact on the drone is actually minimal, and its positive impact far outweighs the negative impact of the increased weight.

[0015] The connector has a compact structure design, with a dedicated small shielded metal shell and welding piece connection, to achieve a perfect anti-interference shielding effect, reliable male and female head locking design, to achieve good contact under the premise of high density.
