Description

Technical Field

[0001] The invention belongs to the technical field of aviation plugs, and in particular relates to an aviation plug mechanism. Background Art

[0002] The aviation plug mechanism is also called the aviation plug mechanism. It is a professional connector with high reliability, strong safety, and easy maintenance and upgrade. The aviation plug is an electromechanical component that connects electrical circuits. The aviation plug mechanism plays an important role in engineering machinery, automated substations, automobile production lines, electrical and motor systems, and instrumentation. In order to ensure the dustproof and waterproof performance of the aviation plug mechanism, the contact part of the plug and the socket will be sealed with special seals or sealing rings.

[0003] A patent application document with publication number CN118693563A discloses a waterproof aviation plug, including a wiring terminal, an interface unit and a plug unit, wherein the interface unit includes an interface body installed on one side of the wiring terminal, and a locking assembly arranged on the outside of the interface body; the plug unit includes a plug assembly inserted into the interface body and cooperating with the locking assembly for preliminarily sealing the interface body, and an adjustment assembly arranged on the outside of the plug assembly for adjusting the matching state of the plug assembly and the locking assembly.

[0004] The plug and the interface of the existing aviation plug mechanism are protected by protective covers before plugging. The protective covers need to be removed respectively before plugging. Then, after the aviation plug mechanism is separated after use, the protective covers are installed on the plug and the interface again.

[0005] The existing aerial plug mechanism needs to remove the protective cover before plugging. When used outdoors, due to the high dust content in the air, after removing the protective cover, the dust in the air will adhere to the plug before plugging, thereby increasing the resistance of the plug, resulting in poor contact and affecting the signal transmission quality. Summary of the invention

[0006] The purpose of the present invention is to provide an aviation plug mechanism, which aims to solve the problem in the prior art that after the protective cover of the aviation plug mechanism is removed before plugging, dust in the air will adhere to the plugging point before plugging, thereby increasing the resistance of the plugging point, resulting in poor contact and affecting the transmission quality of the signal.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an aviation plug mechanism, comprising an interface assembly and a plug assembly, the interface assembly comprising a connecting plate, a sleeve located on the connecting plate and a plurality of conductive parts located in the sleeve, the plug assembly comprising a plug body and a connecting sleeve located at one end of the plug body and coaxial with the sleeve, a plurality of jacks are provided at one end of the plug body, and the plurality of jacks correspond to the plurality of conductive parts respectively.

[0008] A sealing block is slidably sleeved in the sleeve, and a plurality of through grooves are provided on the sealing block and correspond to the plurality of conductive parts respectively. An annular groove is provided on the side of the sealing block away from the connecting plate, and a guide groove connected to the annular groove is provided on the side wall of the sealing block. An annular protective plate is rotatably installed in the annular groove, and a plurality of through holes are provided on the annular protective plate and correspond to the plurality of through grooves respectively. An elastic telescopic rod with one end passing through the guide groove is provided on the side wall of the annular protective plate.

[0009] A circular protective plate is rotatably sleeved inside one end of the connecting sleeve close to the plug body, and a plurality of circular holes are opened on the circular protective plate, which respectively correspond to the plurality of through holes. An inclined transmission groove is opened on the inner wall of the connecting sleeve, and a transmission rod is fixedly installed on the circular protective plate.

[0010] The effect is that by providing a circular protective plate and an annular protective plate, both can be ensured to be in a closed environment before the conductive part is inserted into the socket, thereby preventing external dust from adhering to the conductive part and the socket, which would lead to an increase in resistance at the connection point after the conductive part is inserted into the socket, resulting in poor contact and affecting the signal transmission quality.

[0011] The end of the transmission groove away from the circular protective plate corresponds to the elastic telescopic rod, so that when the plug assembly is plugged into the interface assembly, the elastic telescopic rod can slide into the transmission groove. The transmission rod is a U-shaped rod, and the U-shaped groove of the U-shaped rod opens toward the interface assembly. The two symmetrical rods of the U-shaped rod are respectively located at both ends of the elastic telescopic rod, so that when the plug assembly is plugged into the interface assembly, the elastic telescopic rod can slide into the U-shaped groove. A storage groove extending along the axial direction of the sleeve is provided on the outer wall of the sleeve, which is used to store the elastic telescopic rod and the transmission rod after the plug assembly is plugged into the interface assembly.

[0012] The effect is that, by setting the transmission groove, the circular protective plate and the annular protective plate can automatically rotate when the conductive part moves to the socket, thereby releasing the seal on the conductive part and the socket, allowing the conductive part to be smoothly inserted into the socket, thereby completing the connection between the aviation plug-in mechanism interface assembly and the plug assembly.

[0013] The depth of the transmission groove gradually becomes shallower from one end away from the plug body to the other end. A second clamping groove is opened on the outer wall of the connecting sleeve. The middle part of one end of the second clamping groove is connected with the end of the transmission groove close to the plug body. A second clamping block is slidably sleeved in the second clamping groove.

[0014] A guide sleeve is fixedly installed on the connecting plate and is coaxially sleeved on the outside of the sleeve. A first card slot that penetrates the outer wall of the guide sleeve is opened on the outer wall of the guide sleeve. After the plug assembly is plugged into the interface assembly, the position of the first card slot corresponds to the second card slot. A first card block is slidably sleeved in the first card slot, and the sliding directions of the first card block and the second card block are both perpendicular to the axis of the connecting sleeve.

[0015] The effect is that, by setting the first card block and the second card block, the interface component and the plug component can be automatically connected after the two are plugged in, avoiding the loosening of the plug-in point of the interface component and the plug component after the two are plugged in, thereby ensuring the plug-in stability of the two.

[0016] The side of the first clamping block away from the sleeve is an inclined surface, and the inclined surface gradually inclines in the direction away from the sleeve from one end of the first clamping block away from the plug body to the other end. A limiting groove is provided in the middle of the inner wall of the first clamping groove, and a limiting part slidably installed in the limiting groove is provided in the middle of the first clamping block, and the sliding direction of the limiting part is the same as the sliding direction of the first clamping block.

[0017] The second clamping block is a stepped shaft, the diameter of one end of the stepped shaft close to the plug body is smaller than that of the other end, an elastic anti-slip part is sleeved on the outer wall of the end with a smaller diameter of the stepped shaft, and the two ends of the elastic anti-slip part are respectively fixedly connected to the end with a larger diameter of the stepped shaft and the inner wall of the second clamping groove.

[0018] The effect is that by setting one end of the first card block as an inclined surface, when the plug assembly is plugged into the interface assembly, the protective sleeve can press the first card block into the first card slot through the inclined surface, thereby avoiding the situation where the first card block slides out of the first card slot during plugging and cannot be plugged in smoothly.

[0019] A protective sleeve is installed on the plug body, which is coaxial with the connecting sleeve and sleeved on the outside of the connecting sleeve. The inner wall diameter of the guide sleeve is equal to the outer wall diameter of the connecting sleeve, the outer wall diameter of the guide sleeve is equal to the inner wall diameter of the protective sleeve, the inner wall diameter of the connecting sleeve is equal to the outer wall diameter of the sleeve, and a third slot is opened on the outer wall of the protective sleeve, the third slot corresponds to the second slot, a pressure block is slidably installed in the third slot, and the sliding direction of the pressure block is the same as the sliding direction of the second block, the end of the pressure block away from the connecting sleeve is a sphere, and the other end of the pressure block slides through the protective sleeve and is flush with the inner wall of the protective sleeve.

[0020] One end of the outer wall of the protective sleeve close to the plug body is rotatably sleeved with a rotating ring, and an arc groove is opened on the inner wall corresponding to the rotating ring and the pressing block, and the ball of the pressing block is located in the arc groove.

[0021] The effect is that, by providing the pressing block and the rotating ring, the plug assembly can be released from the interface assembly by rotating the rotating ring, and the plug assembly can be removed from the interface assembly smoothly.

[0022] A plurality of guide grooves extending along the axial direction of the protective sleeve are provided on the inner wall thereof, and the plurality of guide grooves are evenly distributed along the circumferential direction of the protective sleeve. A plurality of guide plates extending along the axial direction of the guide sleeve are fixedly mounted on the outer wall thereof, and the plurality of guide plates are evenly distributed along the circumferential direction of the guide sleeve, and the number of the guide plates is the same as the number of the guide grooves.

[0023] The effect is that the two can be positioned when the plug assembly is plugged into the interface assembly, ensuring that the two can be plugged in smoothly.

[0024] A receiving groove is provided on one side of the plug body where the jack is installed. The receiving groove is an annular shape coaxial with the protective sleeve and is located between the protective sleeve and the connecting sleeve.

[0025] A connecting groove is provided in the middle of one side of the sealing block close to the connecting plate. An elastic reset piece is arranged in the connecting groove. One end of the elastic reset piece is fixedly connected to the inner wall of the connecting groove, and the other end of the elastic reset piece is fixedly connected to the connecting plate.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. By setting a circular protective plate and an annular protective plate, both can be ensured to be in a sealed environment before the conductive part is inserted into the jack, thereby preventing external dust from adhering to the conductive part and the jack, thereby increasing the resistance at the plug-in point after the conductive part is inserted into the jack, resulting in poor contact and affecting the signal transmission quality.

[0028] 2. By providing the first clamping block and the second clamping block, the interface assembly and the plug assembly can be automatically clamped after the two are plugged in, thereby preventing the interface assembly and the plug assembly from becoming loose at the plugging point after the two are plugged in, and ensuring the plugging stability of the two.

[0051] refer to Figure 8 As shown, the circular protective plate 22 is located on the side of the plug body 21 where the plug hole 211 is provided. A plurality of circular holes 221 are opened on the circular protective plate 22, and the plurality of circular holes 221 respectively correspond to the plurality of through holes 162. A transmission rod 222 is fixedly installed on the edge of the circular protective plate 22 away from the plug body 21.

[0052] refer to Figure 3 and Figure 8 As shown, the connecting sleeve 23 is located at one end of the plug body 21 provided with the plug hole 211 and is coaxial with the sleeve 12. The circular protective plate 22 is rotatably sleeved in the connecting sleeve 23. The inner wall diameter of the connecting sleeve 23 is equal to the outer wall diameter of the sleeve 12. The outer wall diameter of the connecting sleeve 23 is equal to the inner wall diameter of the guide sleeve 15. An inclined transmission groove 231 is provided on the inner wall of the connecting sleeve 23. The end of the transmission groove 231 away from the circular protective plate 22 corresponds to the elastic telescopic rod 163, so that the plug assembly 2 is plugged into the interface assembly 1. When the plug assembly 2 is plugged into the interface assembly 1, the elastic telescopic rod 163 can slide into the transmission groove 231, and the transmission rod 222 is a U-shaped rod. The U-shaped groove of the U-shaped rod opens toward the interface assembly 1, and the two symmetrical rods of the U-shaped rod are respectively located at both ends of the elastic telescopic rod 163, so that when the plug assembly 2 is plugged into the interface assembly 1, the elastic telescopic rod 163 can slide into the U-shaped groove. A storage groove 121 extending along its axial direction is provided on the outer wall of the sleeve 12, which is used to store the elastic telescopic rod 163 and the transmission rod 222 after the plug assembly 2 is plugged into the interface assembly 1.

[0053] The depth of the transmission groove 231 gradually becomes shallower from one end away from the plug body 21 to the other end. A second slot 232 is provided on the outer wall of the connecting sleeve 23. The middle part of one end of the second slot 232 is connected to the end of the transmission groove 231 close to the plug body 21. A second block 233 is slidably sleeved in the second slot 232. The second block 233 is a stepped shaft. The diameter of one end of the stepped shaft close to the plug body 21 is smaller than that of the other end.

[0054] The sliding directions of the first clamping block 152 and the second clamping block 233 are both perpendicular to the axis of the connecting sleeve 23 . After the plug assembly 2 is plugged into the interface assembly 1 , the position of the first clamping slot 151 corresponds to the second clamping slot 232 .

[0055] When the plug assembly 2 is plugged into the interface assembly 1, the elastic telescopic rod 163 enters the transmission groove 231 from the end of the transmission groove 231 away from the plug body 21, and also slides into the U-shaped groove of the transmission rod 222. At this time, as the plug assembly 2 is plugged in, the elastic telescopic rod 163 begins to retract at its telescopic end under the action of the transmission groove 231, and at the same time drives the transmission rod 222 and the annular protective plate 161 to rotate. The transmission rod 222 drives the circular protective plate 22 to rotate. The rotation of the annular protective plate 161 causes the multiple through holes 162 on the annular protective plate 161 to rotate to correspond to the multiple through grooves 143 respectively, so that the multiple conductive members 13 can extend out of the multiple through grooves 143. The rotation of the circular protective plate 22 causes the multiple circular holes 221 on the circular protective plate 22 to rotate to correspond to the multiple sockets 211 respectively, so that when the plug assembly 2 is plugged into the interface assembly 1, the multiple conductive members 13 can be inserted into the multiple sockets 211 respectively.

[0056] refer to Figure 3 and Figure 8 As shown, the protective sleeve 24 is fixedly installed on the plug body 21, the protective sleeve 24 is coaxial with the connecting sleeve 23 and is sleeved on the outside of the connecting sleeve 23, the inner wall diameter of the protective sleeve 24 is equal to the outer wall diameter of the guide sleeve 15, the accommodating groove 212 is coaxial with the protective sleeve 24 and is located between the protective sleeve 24 and the connecting sleeve 23, and a third card groove 241 is opened on the outer wall of the protective sleeve 24, the third card groove 241 corresponds to the second card groove 232, a pressure block 242 is slidably installed in the third card groove 241, and the sliding direction of the pressure block 242 is the same as the sliding direction of the second card block 233, the end of the pressure block 242 away from the connecting sleeve 23 is a sphere, and the other end of the pressure block 242 slides through the protective sleeve 24 and is flush with the inner wall of the protective sleeve 24.

[0057] refer to Figure 8 and Fig. 9 As shown, the rotating ring 25 is rotatably sleeved on one end of the outer wall of the protective sleeve 24 close to the plug body 21, and an arc groove 251 is provided on the inner wall corresponding to the rotating ring 25 and the pressing block 242. The ball of the pressing block 242 is located in the arc groove 251, and a plurality of guide grooves 243 extending along the axial direction thereof are provided on the inner wall of the protective sleeve 24. The plurality of guide grooves 243 are evenly distributed along the circumferential direction of the protective sleeve 24, and the number of the guide plates 153 is the same as the number of the guide grooves 243.

[0058] The implementation principle of the embodiment of the present invention is as follows: when the aviation plug-in mechanism is plugged in, one end of the plug body 21 of the plug assembly 2 with the plug hole 211 is aligned with the guide sleeve 15 of the interface assembly 1, and the guide groove 243 on the inner wall of the protective sleeve 24 is aligned with the guide plate 153 on the outer wall of the guide sleeve 15, and then the plug assembly 2 is plugged into the interface assembly 1. At this time, the elastic telescopic rod 163 on the annular protective plate 161 enters the transmission groove 231 from the end of the transmission groove 231 away from the plug body 21, and the elastic telescopic rod 163 slides into the U-shaped groove of the transmission rod 222 at the same time. As the plug assembly 2 is plugged in, the telescopic end of the elastic telescopic rod 163 begins to retract under the action of the transmission groove 231, and at the same time drives the transmission rod 222 and the annular protective plate 161 rotate, and the transmission rod 222 drives the circular protective plate 22 to rotate. When the sealing block 14 contacts the circular protective plate 22, the elastic telescopic rod 163 just slides to the end of the transmission groove 231 close to the plug body 21. At this time, the rotation of the annular protective plate 161 causes the multiple through holes 162 on the annular protective plate 161 to rotate to correspond to the multiple through grooves 143 respectively, so that the multiple conductive parts 13 can extend out of the multiple through grooves 143. The rotation of the circular protective plate 22 causes the multiple circular holes 221 on the circular protective plate 22 to rotate to correspond to the multiple sockets 211 respectively, so that when the plug assembly 2 is plugged into the interface assembly 1, the multiple conductive parts 13 can be respectively inserted into the multiple sockets 211.

[0059] Then continue to insert the plug assembly 2 into the interface assembly 1. At this time, the circular protective plate 22 begins to gradually press the sealing block 14 into the sleeve 12, so that the conductive member 13 gradually extends from the through groove 143 and is inserted into the jack 211. At the same time, the elastic telescopic rod 163 and the transmission rod 222 slide into the receiving groove 121. When the sealing block 14 is completely pressed into the sleeve 12, the first card slot 151, the second card slot 232 and the third card slot 241 are all located in the telescopic direction of the elastic telescopic rod 163. The telescopic end of the elastic telescopic rod 163 can extend into the second card slot 232 under the action of its own elastic force, and push one end of the first card block 152 into the first card slot 151. At the same time, the first card block 152 pushes one end of the second card block 233 into the third card slot 241, and the second card block 233 pushes one end of the pressing block 242 into the arc groove 251, thereby completing the connection between the plug assembly 2 and the interface assembly 1 after being plugged in, and avoiding the plug assembly 2 and the interface assembly 1 from loosening after being plugged in.

[0060] When it is necessary to separate the plug assembly 2 and the interface assembly 1 of the aviation plug mechanism, rotate the rotating ring 25. As the rotating ring 25 rotates, the arc-shaped inner wall of the arc-shaped groove 251 gradually presses the pressing block 242 back into the third slot 241, and the pressing block 242 presses the first clamping block 152 into the first slot 151. The first clamping block 152 presses the second clamping block 233 into the second slot 232. The second clamping block 233 presses the telescopic end of the elastic telescopic rod 163 back into the transmission slot 231. At this time, the first clamping block 152 and the second clamping block 233 can no longer clamp the plug assembly 2 and the interface assembly 1, so that the plug assembly 2 can be pulled out of the interface assembly 1. As the plug assembly 2 gradually detaches from the interface assembly 1, the sealing block 14 is pushed out of the sleeve 12 under the action of the elastic reset member 142. When the sealing block 14 is pushed out After reaching the initial position, the conductive member 13 has been completely retracted from the socket 211 into the through groove 143. At this time, the plug assembly 2 continues to be pulled out of the interface assembly 1, so that the elastic telescopic rod 163 can gradually move away from the plug body 21 along the transmission groove 231. At this time, the elastic telescopic rod 163 drives the transmission rod 222 and the annular protective plate 161 to rotate under the action of the transmission groove 231. The rotation of the annular protective plate 161 causes the through hole 162 to rotate until it no longer corresponds to the through groove 143, so that the annular protective plate 161 can close the outlet of the through groove 143, thereby preventing dust from entering the through groove 143. The transmission rod 222 drives the circular protective plate 22 to rotate. The rotation of the circular protective plate 22 causes the circular hole 221 on the circular protective plate 22 to rotate until it no longer corresponds to the socket 211, thereby preventing dust from entering the socket 211.

[0061] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
