Description

Technical Field

[0001] The present invention belongs to the technical field of cable connectors, and in particular relates to a quick-detachable UAV cable connector. Background Art

[0002] The rapid development of drone technology has led to its widespread use in many industries, including but not limited to agriculture, environmental monitoring, commercial logistics, entertainment, and scientific research. Flying drones can reach many places that are difficult for humans to reach, so when used for filming, the shooting angle is more flexible and changeable, and they can replace humans to go to some dangerous areas, such as disaster areas, fire sites, nuclear radiation areas, etc. In addition to filming tasks, they can also be used for agricultural spraying, cargo transportation, etc. Drone cable connectors are one of the most important components in drone systems. They are responsible for ensuring that data, power, and signals can be transmitted reliably.

[0003] In order to ensure the stable connection of the cable terminals and the stable transmission of signals, most connectors are set to be difficult to unplug easily, and shrapnel is used to lock the position. However, it is inevitable that drones will bump into each other during flight. Once the shrapnel is bumped, it is easy to be damaged and lose the ability to rebound, making the connection between the terminals no longer firm. At the same time, since drones may make various flying postures when flying in the air, most drones have corresponding grooves inside to place connectors. The top of the groove is often equipped with fixing components such as buckles to prevent the connector from falling out of the groove. This makes it difficult for staff to remove the connector from the groove when inspecting and maintaining the connector, affecting the staff's inspection efficiency. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] like Figure 1 - Fig. 9 As shown, this embodiment provides a quick-detachable drone cable connector, including an inner terminal 1, an outer terminal 2 and a bottom plate 3. The outer terminal 2 is designed to be open at one end. The inner terminal 1 is plugged into the outer terminal 2. The side wall of the inner terminal 1 away from the outer terminal 2 is fixedly connected with an expansion block 4. The shape of the expansion block 4 is consistent with the shape and size of the outer terminal 2. Therefore, when the inner terminal 1 is fully inserted into the outer terminal 2, the expansion block 4 will also abut against the outer terminal 2 and fit together as closely as possible, effectively preventing the inner terminal 1 from separating from the outer terminal 2. The bottom plate 3 is fixedly connected to the bottom wall of the outer terminal 2. The side walls on both sides of the inner terminal 1 are respectively provided with fixing holes 5. The side walls on both sides of the outer terminal 2 are respectively provided with through holes 6. The top wall of the bottom plate 3 is provided with two transverse grooves 7. The inner walls of the two transverse grooves 7 are respectively slidably connected with vertical rods 8. The longitudinal section of the transverse groove 7 is an inverted "T" shape, and the longitudinal section of the vertical rod 8 is also an inverted "T" shape. In order to ensure that the vertical rod 8 can slide stably along the transverse groove 7, both are set to a "T" shape. The side wall of the vertical rod 8 facing the through hole 6 is fixedly connected to a side rod 9, the side rod 9 passes through the through hole 6 and is inserted into the fixing hole 5, and the side wall of the vertical rod 8 facing away from the inner terminal 1 is fixedly connected to a connecting rod 10, the shape of the connecting rod 10 is "L" shaped, and the bottom wall of the connecting rod 10 is fixedly connected to a vertical rod 48.

[0033] The top wall of the outer terminal 2 is fixedly connected with a fixed sleeve 11, and the longitudinal section of the fixed sleeve 11 is in the shape of a "mouth". The top wall of the inner terminal 1 is fixedly connected with a fixed block 12, and the side wall of the fixed block 12 facing the outer terminal 2 is fixedly connected with a top block 13, and the top block 13 is inserted into the fixed sleeve 11. Both ends of the fixed sleeve 11 are open. When the inner terminal 1 is fully inserted into the outer terminal 2, the top block 13 can also be fully inserted into the fixed sleeve 11. The top wall of the outer terminal 2 is also fixedly connected with a control box 14, which is located on the side of the fixed sleeve 11 facing away from the top block 13. The control box 14 is installed with an ejection mechanism for ejecting the top block 13, and the ejection mechanism includes a turning handle 18, a telescopic rod 19, a top gear 20, a longitudinal rack 21, a push plate 22 and a buffer block 23. A groove 24 is opened on the top wall of the control box 14, and the turning handle 18 is located in the groove 24. Two magnetic sheets 29 are fixedly connected to the bottom wall of the groove 24, and the material of the turning handle 18 is magnetic metal. A pull ring 35 is installed on the top wall of the turning handle 18, and the side wall of the pull ring 35 is attached with magnets. When the drone is working, the pull ring 35 will fall on the top wall of the turning handle 18. Due to the magnetic setting, the pull ring 35 will be stably "sticked" to the surface of the turning handle 18 to ensure that the pull ring 35 will not collide back and forth when the drone is performing some actions.

[0034] The bottom wall of the turning handle 18 is fixedly connected to one end of the telescopic rod 19. The end of the telescopic rod 19 away from the turning handle 18 passes through the bottom wall of the groove 24 and is fixedly connected to the top wall of the top gear 20. The telescopic rod 19 here is a telescopic component that can transmit the rotation effect. This setting ensures that the rotation of the pull ring 35 can drive the top gear 20 to rotate. A partition 25 is fixedly installed in the control box 14, and the longitudinal rack 21 is slidably connected to the top wall of the partition 25. The top wall of the partition 25 is provided with a first slide groove 27. The bottom of the longitudinal rack 21 is fixedly connected to a first slide bar 26, and the first slide bar 26 is slidably connected to the inner wall of the first slide groove 27. The longitudinal rack 21 is meshed with the top gear 20, and a placement groove 28 is provided on the side of the control box 14 facing the fixed sleeve 11. The push plate 22 is located in the placement groove 28, and the push plate 22 is opposite to the top block 13. The two ends of the longitudinal rack 21 pass through the side walls of the control box 14 on both sides respectively, and the end of the longitudinal rack 21 facing the fixed sleeve 11 is fixedly connected to the side wall of the push plate 22, and the buffer block 23 is fixedly connected to the side wall of the push plate 22 facing away from the longitudinal rack 21. The buffer block 23 is made of a deformable material, such as rubber, to ensure that when the longitudinal rack 21 drives the push plate 22 to push the top block 13, the buffer block 23 will be deformed first.

[0035] The control box 14 is also provided with a synchronization mechanism for controlling the movement of the connecting rod 10. The synchronization mechanism includes a rotating rod 30, a bottom gear 31, and two side racks 32. One end of the rotating rod 30 passes through the partition 25 and is fixedly connected to the bottom wall of the top gear 20. The other end of the rotating rod 30 is fixedly connected to the top wall of the bottom gear 31. The arrangement of the rotating rod 30 enables the top gear 20 to drive the bottom gear 31 to rotate together. The bottom gear 31 is rotationally connected to the bottom wall of the control box 14. Two second slide grooves 33 are provided on the bottom wall of the control box 14. The bottom walls of the two bottom gears 31 are respectively fixedly connected with second slide bars 34. The two second slide bars 34 are respectively slidably connected to the inner walls of the two second slide grooves 33. The two side racks 32 are respectively located on both sides of the bottom gear 31. The two side racks 32 are meshed with the bottom gear 31. One end of the side rack 32 passes through the side wall of the control box 14. As shown in the attached manual Figure 1 , Figure 2 and Figure 6 It can be seen that the side wall of the control box 14 is pre-set with holes for the side rack 32 to move. The end of the connecting rod 10 away from the vertical rod 8 is fixedly connected to the bottom wall of the side rack 32.

[0036] The bottom plate 3 is provided with limiting holes 15 at four corners, and fixing rods 16 are provided in the four limiting holes 15, respectively. The fixing rods 16 are fixedly provided inside the drone (not shown in the figure), and the bottom plate 3 is sleeved on the fixing rods 16 through the limiting holes 15, so that the staff can quickly install the external terminal 2 and the bottom plate 3. A cavity is provided in the bottom plate 3, and a swing groove 17 is provided on the side wall of the bottom plate 3 facing away from the internal terminal 1.

[0037] The swing slot 17 is connected to the cavity, the cavity is connected to the limiting hole 15, the side wall of the swing rod 36 is against the side wall of the cavity, and a fixing mechanism for fixing the bottom plate 3 is installed in the cavity, and the fixing mechanism includes the swing rod 36, the center rod 37, the motion rod 38 and two telescopic springs 40. The center rod 37 is fixedly arranged in the cavity, the swing rod 36 is "L" shaped, the center rod 37 is arranged at the inflection point of the swing rod 36, the swing rod 36 rotates around the center rod 37, one end of the swing rod 36 extends out of the swing slot 17, the side wall of the swing rod 36 is against the side wall of the vertical rod 48, and the length of the swing rod 36 extending out of the swing slot 17 is enough to enable the vertical rod 48 to push the swing rod 36 to rotate. An empty slot 41 is provided on the side wall of the swing rod 36 at one end away from the vertical rod 48, and a short rod 42 is fixedly arranged in the empty slot 41. A moving slot 43 is provided on the side wall of the moving rod 38, and the short rod 42 is located in the moving slot 43. When the swing rod 36 rotates, the short rod 42 will slide in the moving slot 43, thereby causing the moving rod 38 to move along the third sliding slot 46. Two limiting rods 44 are fixedly connected to the side wall of the moving rod 38 facing the two fixed rods 16, and a plug hole 45 is provided on the side wall of the fixed rod 16 facing the moving rod 38. The two limiting rods 44 are respectively inserted into the two plug holes 45. Two third sliding slots 46 are provided on the bottom wall of the cavity, and two third sliding rods 47 are fixedly connected to the bottom wall of the moving rod 38. The two third sliding rods 47 are respectively slidably connected to the inner walls of the two third sliding slots 46. One end of the telescopic spring 40 is fixedly connected to the side wall of the third slide bar 47, and the other end is fixedly connected to the side wall of the third slide groove 46. The force applied by the telescopic spring 40 to the third slide bar 47 will keep the limiting rod 44 inserted into the insertion hole 45. At the same time, the telescopic spring 40 will not only fix the limiting rod 44, but also have a certain fixing effect on the side rack 32 at the other end of the connecting rod 10, and at the same time, the synchronization mechanism and the ejection mechanism will also be fixed in position.

[0038] The working principle of this embodiment is as follows: when installing the cable connector, the inner terminal 1 can be directly inserted into the outer terminal 2. Since the end of the inner terminal 1 close to the outer terminal 2 is designed to be arc-shaped, when the inner terminal 1 is inserted into the outer terminal 2, the two side rods 9 will be squeezed outward, so the inner terminal 1 can be directly inserted into the outer terminal 2. When the inner terminal 1 is fully inserted into the outer terminal 2, the side rods 9 will be inserted into the fixing hole 5.

[0039] At the same time, the top block 13 on the top of the inner terminal 1 will also be inserted into the fixing sleeve 11 on the top of the outer terminal 2. When the inner terminal 1 is fully inserted into the outer terminal 2, the top block 13 will also be in a state of abutting against the buffer block 23.

[0040] When the staff needs to remove the inner terminal 1 and the outer terminal 2, they can first pull the pull ring 35 to a vertical state, so that the pull ring 35 is pulled upward out of the turning handle 18, and then the pull ring 35 is turned. While the turning handle 18 is turned, the top gear 20 is driven to rotate along with the pull ring 35 through the telescopic rod 19, and the longitudinal rack 21 meshed with the top gear 20 will move along the first slide groove 27, and the push plate 22 and the buffer block 23 fixed on the longitudinal rack 21 will push the top block 13 away from the outer terminal 2. Since the buffer block 23 has a deformation ability, when the top block 13 is first pushed, the top block 13 will not move directly, but will cause the buffer block 23 to deform first;

[0041] During the rotation of the top gear 20, the rotating rod 30 fixed at the bottom of the top gear 20 will drive the bottom gear 31 to rotate together, and the two side racks 32 meshing with the bottom gear 31 will move toward the two sides of the control box 14, and the connecting rod 10 fixed at the bottom of the side racks 32 will move with the side racks 32, so that the vertical rod 8 drives the side rod 9 to leave the through hole 6 and the fixing hole 5. At this time, the restriction relationship between the inner terminal 1 and the outer terminal 2 is released, which is convenient for subsequent staff to remove the inner terminal 1;

[0042] When the connecting rod 10 moves outward, the vertical rod 48 at the bottom of the connecting rod 10 will also drive the swing rod 36 to rotate around the central rod 37, and the short rod 42 in the empty groove 41 opened at one end of the swing rod 36 will move along the moving groove 43 on the side wall of the moving rod 38, thereby driving the moving rod 38 to move away from the fixed rod 16, thereby compressing the telescopic spring 40 and causing the limiting rod 44 to leave the socket 45 on the side wall of the fixed rod 16, so that the bottom plate 3 and the external terminal 2 can easily leave the fixed rod 16, making it convenient for the staff to take out the external terminal 2 and the bottom plate 3.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
