Description

Technical Field

[0001] The present invention relates to the field of drone cable connectors, and in particular to a drone cable connector. Background Art

[0002] Drone cable connectors are an important component of drone systems, used to connect various electronic devices and sensors to ensure reliable transmission of signals and power.

[0003] In the prior art, the cable connector of the drone generally adopts a plug-in structure, and in order to be waterproof, a waterproof cover is usually provided, and in order to prevent loosening, the male head and the female head are usually fixed by threaded connection with a threaded sleeve. However, when the above structure is used, on the one hand, although the waterproof cover can protect the preserved female head, the existing waterproof cover is usually independent, and the waterproof cover needs to be put away when the drone is used, which will cause the risk of loss. On the other hand, although the threaded sleeve connecting the male head and the female head can achieve a strong fixation effect, it will inevitably produce vibration when the drone is used. Therefore, over a long period of time, when there is no external pressure to fix, the threaded sleeve between the male head and the female head will slip and strip, or cause a certain degree of damage to the thread, which will affect the connection between the male head and the female head and affect the use of the drone. Based on this, the present invention designs a drone cable connector. Summary of the invention

[0006] A circular convex block, wherein the outer side of the convex block is provided with a thread layer and is threaded with the inner side of the waterproof cover.

[0007] In the above-mentioned drone cable connector, the bottom of the waterproof cover is connected to the outer cover 2, the mounting plate adopts a circular structure, an annular sealing layer is embedded in the mounting plate, the outer cover 2 and the outer cover 1 have the same size and both meet the conditions of sealing against the sealing layer.

[0008] In the above-mentioned drone cable connector, the dust and waterproof component includes a dual-purpose pump, which is arranged in the mounting platform. One end of the dual-purpose pump is connected to the connecting pipe, and the other end of the dual-purpose pump is connected to a discharge pipe. The discharge pipe passes through the side of the mounting platform and is connected to the outside world. A one-way valve is arranged at the connection between the connecting pipe and the mounting platform.

[0009] In the above-mentioned drone cable connector, the row tube passes through the axis of the protrusion and is coaxially arranged with the protrusion.

[0010] In the above-mentioned drone cable connector, the connecting tube adopts a bellows structure.

[0011] In the above-mentioned drone cable connector, the anti-loosening component includes two symmetrically arranged connecting blocks, each of the connecting blocks is rotatably connected to a rotating rod, the other end of each rotating rod is connected to a pressure plate, the middle part of the rotating rod is connected to a guide rod through a slider, the two guide rods pass through the top of the mounting platform together, and the bottom of each guide rod is sleeved with a sleeve, which is fixedly connected to the inner bottom of the mounting platform.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention provides a waterproof cover to keep the female connector clean when the male connector and the female connector are not connected, thereby preventing the female connector from being contaminated. At the same time, the present invention also provides a boss on the side of the mounting platform, so that when the male connector and the female connector are in a connected state, the waterproof cover can be fixed on the boss on the side of the mounting platform, thereby preventing the waterproof cover from being lost.

[0013] 2. In actual use, the present invention is designed with an anti-loosening component. When the male head and the female head are in a connected state, the two pressure plates in the anti-loosening component can apply pressure to both sides of the male head outer cover 1 to achieve a stable connection between the male head and the female head. This can reduce the impact of the vibration generated by the drone during use on the threaded sleeve and increase the service life of the parts.

[0014] 3. The present invention is also provided with a dust-absorbing and waterproof component.

DETAILED DESCRIPTION

[0023] Reference Figure 1-7A drone cable connector includes a mounting platform 1, a mounting groove 2 for connector installation is provided in the mounting platform 1, a connector 3 is fixedly provided in the mounting groove 2, the connector 3 is connected to a mounting plate 4 and fixed in the mounting groove 2 by bolts, an annular sealing layer 9 is provided in the mounting plate 4, the connector 3 includes a female head 31 and a male head 32, the other end of the male head 32 is connected to the cable, the male head 32 is rotatably connected with a threaded sleeve 33, the threaded sleeve 33 is threadedly connected to the mounting portion provided on the outer side of the female head 31, and the threaded sleeve 33 is used to tightly connect the male head 32 and the female head 31 The outer cover 34 can cooperate with the threaded sleeve 33 to achieve waterproof and sand-proof effects on the connection between the male head 32 and the female head 31 when the two are installed. At the same time, the bottom of the outer cover 34 can achieve negative pressure fixation with the sealing layer on the mounting plate 4 through a wider annular surface. This can reduce the fixing strength between the threaded sleeve 33 and the mounting plate 4 when the drone is in the air, and reduce the problem of large vibrations caused by excessive wind force on the mounting part of the threaded sleeve and the female head 31, which may damage the thread of the threaded sleeve 33. The waterproof cover 5 is connected to the female connector 31 to achieve waterproof protection for the female connector 31 when the connector is not connected. The waterproof cover 5 is connected with the outer cover 2 56. The two have the same principle as the threaded sleeve 33 and the outer cover 1 34 to protect the connector. The outer cover 2 56 and the outer cover 1 34 both meet the conditions of sealing against the sealing layer 9, and the sealing layer 9 is set as a multi-fold rubber structure, so that when the inner part of the outer cover is pumped and pressed, the sealing layer 9 and the outer cover can be fixed to each other. At the same time, the top of the waterproof cover 5 is fixedly connected with a fixing cylinder 51, the outer side of the fixing cylinder 51 is sleeved with a sleeve shaft 52, and the side of the sleeve shaft 52 is connected with a connecting pipe 53, and the connecting pipe 53 is connected to the connecting channel 54 opened on the inner side of the sleeve shaft 52, thereby forming a gas flow channel, so that the air inside the waterproof cover 5 can be The gas can be discharged through the fixed cylinder 51, the connecting pipe 53 and the connecting channel 54. The connecting pipe 53 adopts a bellows structure, which can meet the requirements of expansion, extension and bending. The inner wall of the fixed cylinder 51 is provided with a connecting hole 55 connected to the connecting channel 54. Through the connecting hole 55, when the fixed cylinder 51 and the sleeve shaft 52 rotate relative to each other, the gas can still flow from the fixed cylinder 51 to the connecting pipe 53. The connecting pipe 53 is connected to a dust-absorbing and waterproof component 6 for absorbing dust from the female head 31. The dust-absorbing and waterproof component 6 includes a dual-purpose pump 61. The dual-purpose pump 61 is arranged inside the mounting platform 1. One end of the dual-purpose pump 61 is connected to the connecting pipe 53, and the other end of the dual-purpose pump 61 is connected to a discharge pipe 62. The discharge pipe 62 passes through the side of the mounting platform 1 and is connected to the outside world. A one-way valve 63 is provided at the connection between the connecting pipe 53 and the mounting platform 1.

[0024] The anti-loosening component 7 is arranged in the mounting platform 1 and applies vertical downward pressure to the male head 32. The anti-loosening component 7 includes two symmetrically arranged connecting blocks 71, each connecting block 71 is rotatably connected to a rotating rod 72, and the other end of each rotating rod 72 is connected to a pressure plate 73. The middle part of the rotating rod 72 is connected to a guide rod 75 through a slider 74. The two guide rods 75 pass through the top of the mounting platform 1 together, and the bottom of each guide rod 75 is sleeved with a sleeve 76. The sleeve 76 is fixedly connected to the inner bottom of the mounting platform 1. The connecting pipe 53 connected to the dual-purpose pump 61 is respectively connected to the upper side of the two sleeves 76 through a branch pipe 77. The piston 78 and the inner bottom of the sleeve 76 are connected to a spring 79. The dual-purpose pump 61 can be used to pressurize and inflate the two sleeves 76, thereby driving the two guide rods 75 to move downward, so that the two pressure plates 73 can be driven to fix the outer cover 34.

[0025] A circular protrusion 8 is fixedly connected to the side of the mounting platform 1, and a threaded layer is provided on the outer side of the protrusion 8 and is threadedly connected to the inner side of the waterproof cover 5. The protrusion 8 can be used to fix the waterproof cover 5 when the female head 31 and the male head 32 in the connector are in a connected state, and the drain pipe 62 passes through the axis of the protrusion 8 and is coaxially arranged with the protrusion 8. In this way, when the waterproof cover 5 is mounted on the protrusion 8, the interior of the waterproof cover 5 is connected to the pipe mouth of the drain pipe 62, so that gas can enter the sleeve 76 through the waterproof cover 5, the drain pipe 62, the dual-purpose pump 61 and the connecting pipe and the branch pipe 77, so that dust or impurities in the waterproof cover 5 can be temporarily input into the sleeve 76 for storage, so that after the waterproof cover 5 is fixed to the protrusion 8, the above-mentioned impurities can be output again through the drain pipe 62, so as to achieve the negative pressure cleaning effect on the inside of the waterproof cover 5.

[0026] The present invention has two working modes: In working mode one, the waterproof cover 5 is threadedly connected to the mounting part of the female head 31, and the connector is in a disconnected state at this time. The dual-purpose pump 61 outputs negative pressure to the connecting pipe 53 at this time, and the female head 31 is protected from water and dust through the waterproof cover 5. On the one hand, the negative pressure makes the outer cover 2 56 connected to the waterproof cover 5 tightly connected to the sealing layer 9. On the other hand, the dust inside the female head 31 is output to the drain pipe 62 through the waterproof cover 5, the fixing tube 51, the sleeve shaft 52 and the connecting pipe 53 under the negative pressure operation of the dual-purpose pump 61. At this time, since the protrusion 8 is not sealed with the waterproof cover 5, the pipe mouth of the drain pipe 62 is in an open state. Therefore, the dust and condensed water inside the female head 31 can be discharged outward through the drain pipe 62, so as to keep the female head 31 clean for a long time.

[0027] In working mode 2, the waterproof cover 5 is fixed on the protrusion 8. At this time, the connector is in a connected state. The threaded sleeve 33 on the male head 32 is threadedly fixed to the mounting portion on the female head 31. The outer cover 1 34 and the sealing layer 9 fit each other. At this time, the dual-purpose pump 61 outputs negative pressure to the drain pipe 62. At this time, since the drain pipe 62 is located in the waterproof cover 5 and is sealed by the waterproof cover 5, the negative pressure output to the drain pipe 62 will cause the dust and water droplets in the waterproof cover 5 to enter the branch pipe 77 and the sleeve 76 through the drain pipe 62. The connection between the branch pipe 77 and the sleeve 76 is located above the piston 78, so the dust When impurities and other solids enter the sleeve 76, the position of the piston 78 will move downward, which will drive the guide rod 75, thereby driving the two pressure plates 73 to move downward, thereby achieving pressure fixation on the outer cover 34 and improving the stable connection state of the connector. When the connector connection is completed, the waterproof cover 5 is re-fixed on the mounting portion of the female head 31. At this time, the dual-purpose pump 61 outputs positive pressure to the discharge pipe 62, so that the impurities in the sleeve 76 above the piston 78 can be discharged through the discharge pipe 62, thereby facilitating the subsequent temporary accommodation function of the sleeve 76 for solid impurities and facilitating operation.
