Embodiment 1

[0028] Such as figure 1 As shown, the new miniature drone provided by the present invention is connected with wires including a wire core composed of a copper wire conductor 10 and an insulating layer 20 covering the outside of the wire core; wherein the copper wire conductor 10 is preferably TR Type soft copper wire, the insulating layer 20 is made of high-density polyethylene material.

[0029] Preferably, the core is formed by twisting 40 TR-type soft copper wires, and the twisted pitch diameter ratio of the 40 TR-type soft copper wires, that is, the ratio of the pitch length to the outer diameter of the strands is not more than 8. , May be preferably 6.

[0030] Different from the existing general cables, the copper wire conductor 10 in the present invention adopts a thinner copper wire than the sixth type conductor. The diameter of the copper wire conductor 10 is not greater than 0.1 mm, preferably 0.08 mm; the length of the copper wire conductor 10 The rate may preferably be...

Embodiment 2

[0039] Such as image 3 As shown, the wire for internal connection of the novel micro-UAV provided in this embodiment has stronger bending resistance than the first embodiment. Specifically, the difference between this embodiment and the first embodiment is that the wire core is not directly twisted by 40 TR-type soft copper wires, but is first twisted into an intermediate conductor 40 from TR-type soft copper wires, and then the intermediate conductor 40 The wires are twisted directly into the core and twisted twice, so that the wire for internal connection of the micro-UAV provided in this embodiment has extremely strong bending resistance. fracture.

[0040] Specifically, each intermediate conductor 40 is formed by twisting a plurality of TR-type soft copper wires, and the stranding direction of the plurality of TR-type soft copper wires is leftward, and the plurality of TR-type soft copper wires are twisted. After twisting and twisting, a plurality of middle 40 is obtained. ...

Embodiment 3

[0047] Such as Figure 4 As shown, the wire for internal connection of the novel micro-drone provided in this embodiment has a larger cross-sectional area than the first embodiment, and is suitable for models with larger currents.

[0048] Specifically, the difference between this embodiment and the first embodiment is that the wire core adopts a composite stranding process structure. First, a plurality of copper wire conductors 10 are twisted into a plurality of inner core conductors 30 according to a certain twist pitch ratio, and the outer surface of each inner core conductor 30 is covered with tissue paper, and then a plurality of inner core conductors 30 The wire cores are twisted according to a certain stranded pitch diameter ratio. The stranded voids of each inner core conductor 30 can be filled with a filling layer. The filling layer can preferably be a flexible polyester-cotton fiber rope or a flexible The reinforcing ribs are made to make the stranded inner core conduc...

Abstract

The invention discloses a new-type wire for micro-unmanned aerial vehicle internal connection and a preparation method thereof. The new-type wire for the micro-unmanned aerial vehicle internal connection includes a wire core composed of a copper wire conductor, and an insulating layer coated on the outside of the wire core; wherein the copper wire conductor is a TR type soft copper wire; and the insulating layer is made of a high-density polyethylene material. The preparation method of the new-type wire for the micro-unmanned aerial vehicle internal connection includes conductor stranding andouter extrusion. The new-type wire for the micro-unmanned aerial vehicle internal connection provided by the invention has the characteristics of bending resistance, cold resistance and lightness, which provides a guarantee for the use of the unmanned aerial vehicle in a special environment.

Description

Technical field [0001] The invention relates to the technical field of power cables, in particular to a new type of electric wire for internal connection of a miniature drone and a preparation method thereof. Background technique [0002] With the maturity of drone technology, especially the popularity of micro drones, more and more micro drones are used in special occasions and special environments, which puts forward new requirements for the adaptability of drones. Among them, the wire used as the nerve transmission channel of the drone, whether it can adapt to the special environment plays a key role for the drone. Conventional wires are not suitable for special environments, especially in low temperature areas, which can no longer meet the market's demand for wires for internal connection of micro drones. [0003] Therefore, there is an urgent need to develop a new type of wire for internal connection of micro drones to meet market demand, which is the development trend of wir...
