[0003] The current unmanned aerial vehicle connector on the market only has a high-voltage module connector, and in most cases uses an independent interface design. The independent interface needs to configure contacts and plug-in male heads for each phase line and ground line, which will result in a large overall size of the connector, increasing the load of the unmanned aerial vehicle and affecting its endurance. In addition, the three-phase lines at the back end of the connector are distributed randomly, and during the flight of the unmanned aerial vehicle, the frequent movement of the three-phase lines may cause mutual friction and wire pulling between the three-phase lines, increasing the overall failure rate of the unmanned aerial vehicle.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0046] ​​​The embodiments are described below according to the overall structure of the present application.

[0047] Embodiment one: please refer to Figures 1-12 The unmanned aerial vehicle high-voltage connector shown in the figure comprises a plug male head 1, a plug female head 2, a male head rear cover 3, a sliding mechanism, a sealing mechanism and a limiting mechanism. A plurality of hole grooves are formed on the male head rear cover 3. The worker places the three-phase line 4 immersed in tin after stripping in the three-phase female head 9, clamps the three-phase line 4 and the three-phase female head 9 by means of a tool, then inserts the three-phase line 4 into the hole grooves formed on the male head rear cover 3 correspondingly, so that the three-phase line 4 is placed separately and is prevented from swinging and wearing with other structural parts. The indirect contact of the three-phase line 4 connection part with other structural parts is reduced, the overall failure rate of the unmanned aerial vehicle is effectively reduced, one end of the signal line 16 penetrates into the plug female head 2, the pin header 17 is connected in the plug female head 2, the signal line 16 is connected with the female header 18, the pin header 17 and the female header 18 at one end of the signal line 16 are inserted, the integration of the low-voltage module is realized, the sealing glue is poured after fixing, and the inner wall of the male head rear cover 3 is provided with the plastic spring 10 at the hole groove. Since the outer diameter of one end of the three-phase female head 9 is greater than that of the other end, the plastic spring 10 is stretched during the inward sliding process.

[0048] The different outer diameters of the three-phase female head 9 at both ends form a clamping groove 14 at the middle position. When the plastic elastic sheet 10 is located at the clamping groove 14, it is reset by the elastic effect of the plastic elastic sheet 10 itself, and is waterproof and fixed to prevent dragging. A tapered ring 15 is arranged on the outer wall of the three-phase female head 9 on the side of the clamping groove 14. When the three-phase female head 9 continues to slide to one side, the plastic elastic sheet 10 is located on the outer wall of the tapered ring 15. Then, the staff inserts the three-phase male pin 5 into the inside of the plug-in female head 2 and the plug-in male head 1 to the inside of the three-phase female head 9, realizing the integration of the high-voltage module. The integration of the low-voltage module and the high-voltage module reduces the overall volume and the load of the unmanned aerial vehicle, and ensures the endurance of the unmanned aerial vehicle. The space in the module is used to glue the wire insertion part, which can effectively protect and greatly improve the waterproof and dustproof ability. When the three-phase male pin 5 at one end contacts and inserts the three-phase wire 4 in the three-phase female head 9, the first threaded hole 7 is arranged on the plug-in male head 1 and the male head rear cover 3, and the second threaded hole 8 is arranged on the outer wall of the plug-in male head 1 and the plug-in female head 2. The first threaded hole 7 and the second threaded hole 8 are matched by the bolt assembly, and the assembly gap is protected by the sealing glue. The plug-in male head 1 and the plug-in female head 2 are fixed by the cooperation of the second threaded hole 8 and the bolt assembly, and the male head rear cover 3 is inserted into the plug-in male head 1. Since the plug-in male head 1 is provided with a plug hole 6 for inserting the three-phase female head 9, when the three-phase female head 9 is completely inserted into the plug hole 6, it continues to slide to one side, which pushes the plastic elastic sheet 10 to reset and move on the outer wall of the tapered ring 15.

[0049] Since the three-phase female head 9 is elastically penetrated by the top rod 12, one end of the top rod 12 is connected with the clamping plate 13 in the three-phase female head 9. During the sliding process of the plastic elastic sheet 10, the top rod 12 is pressed, which drives the clamping plate 13 at the bottom to slide down. Since one end of the three-phase wire 4 is located on one side of the clamping plate 13 in the initial state, and the three-phase male pin 5 contacts the three-phase wire 4 at this time, one end of the three-phase male pin 5 is located at the bottom of the clamping plate 13. Under the action of the top rod 12, the clamping plate 13 limits and clamps the three-phase male pin 5. Then, the male head rear cover 3 and the plug-in male head 1 are fixed by the cooperation of the first threaded hole 7 and the bolt assembly, thereby completing the overall fixing and installation work. The three-phase female head 9 is limited by the clamping groove 14, which can prevent the three-phase wire 4 from sliding back out, thereby ensuring the stability of the connection between the three-phase male pin 5 and the three-phase wire 4, preventing the three-phase male pin 5 and the three-phase wire 4 from slipping off during the flight shaking of the unmanned aerial vehicle, and effectively reducing the overall failure rate of the unmanned aerial vehicle.

[0050] In the above embodiment, please refer to Figure 3 andFigure 6 Wherein the female adapter 2 is provided with a flat hole, and the outer wall of the three-phase male pin 5 is provided with a horizontal surface matched with the flat hole. The flat hole ensures that the three-phase male pin 5 is consistent in inclination when inserted into the female adapter 2, preventing the three-phase male pin 5 from being inclined, and avoiding the need to adjust the angle of the three-phase male pin 5 after installation.

[0051] In the above embodiment, please refer to Figure 7 The inner wall of the three-phase female head 9 is provided with an inner groove 11, and the depth of the inner groove 11 is greater than the thickness of the clamping plate 13. The inner groove 11 facilitates the clamping plate 13 to be clamped into the inner groove 11 by the ejector rod 12, and the depth of the inner groove 11 ensures that the clamping plate 13 is completely in the inner groove 11, preventing the clamping plate 13 from hindering the sliding connection of the three-phase male pin 5, and further improving the stability of the overall installation.

[0052] In the above embodiment, please refer to Figure 11 The inner wall of the clamping plate 13 is provided with a flexible protective sleeve, which is detachably arranged on the inner wall of the clamping plate 13. The flexible protective sleeve prevents the clamping plate 13 from directly contacting the outer wall of the three-phase male pin 5, effectively preventing the outer wall of the three-phase male pin 5 from being worn during the clamping process. The flexible protective sleeve is made of insulating material, which can prevent electric leakage, and the detachable arrangement facilitates regular maintenance and replacement by the staff.

[0053] Embodiment two: please refer to Figure 7 and Figure 10 The overall structure is similar to that of embodiment one. One end of the plastic elastic sheet 10 is concave, and the inner wall of the plastic elastic sheet 10 is provided with a tapered surface. The connection between one end of the plastic elastic sheet 10 and the tapered ring 15 is smooth, and the outer diameter of one end of the tapered surface is the same as the inner diameter of the plastic elastic sheet 10. The concave arrangement facilitates the extrusion of the ejector rod 12 during the subsequent elastic reset process, and the tapered surface allows the plastic elastic sheet 10 to slide away from the outer wall of the tapered ring 15 during the sliding process of the three-phase female head 9. Thus, the plastic elastic sheet 10 can still limit and fix the tapered ring 15, and after the plastic elastic sheet 10 extrudes the ejector rod 12, the outer wall of the tapered ring 15 will be in full contact with the inner wall of the plastic elastic sheet 10, further sealing the slot of the ejector rod 12 and effectively preventing the sliding of the ejector rod 12 during subsequent gluing.

[0054] In the above embodiment, please refer to Figure 10The outer wall of the push rod 12 and one end of the plastic spring 10 are arc-shaped, and a smooth surface is provided at the arc-shaped end face. The arc shape facilitates the movement of the plastic spring 10 to the top of the push rod 12 when it slides through the outer wall of the conical ring 15 to complete the compression work. The smooth surface of the arc-shaped end face effectively reduces the sliding friction between the two, ensuring the stability of the plastic spring 10 sliding at the push rod 12.

[0055] In practical operation, this invention is used by fixing the stripped and tinned three-phase wires 4 to the three-phase female connector 9. Then, each set of three-phase wires 4 is inserted into the plastic spring 10 of the male connector back cover 3. At this time, one end of the plastic spring 10 will be pressed against the conical ring 15. The three-phase male pin 5 passes through the female connector 2 and the male connector 1 and is inserted into the three-phase female connector 9, so that the three-phase wires 4 are separated and placed separately. After the three-phase wires 4 are connected, they avoid swinging and wear with other structural components. At the same time, it reduces the indirect contact between the three-phase wires 4 and other structural components, effectively reducing the overall failure rate of the UAV. Furthermore, the male connector 1, the female connector 2 and the male connector back cover 3 are limited and fixed by the bolt assembly, so that there will be no situation where a bunch of three-phase wires 4 are exposed and hanging outside after being connected.

[0056] Simultaneously, when the male connector back cover 3 is inserted into the socket 6 inside the male connector 1, one end of the socket 6 will push the three-phase female connector 9 to slide to one side. At this time, the plastic spring 10 will be stuck in the slot 14 of the three-phase female connector 9. The slot 14 limits the three-phase female connector 9, preventing the three-phase wire 4 from sliding out. The plastic spring 10 will also squeeze the push rod 12 on the three-phase female connector 9. During this process, the push rod 12 drives the clamping plate 13 at the bottom to limit and clamp the three-phase male pin 5, thereby ensuring the stability of the connection between the three-phase male pin 5 and the three-phase wire 4 and preventing the three-phase male pin 5 from slipping off the three-phase wire 4 during the drone's flight.

[0057] The high-voltage connector of this invention integrates high-voltage and low-voltage modules by realizing the plug-in connection of phase wires and the pin header connection of signal wires, resulting in a smaller product size, no risk of wear, and higher safety.

[0058] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
