Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0019] Example 1

[0020] A kind of aviation plug waterproof wet plug type connector for intelligent gateway, such as Figures 1-4As shown, including the connection shell 1, the middle of the connection shell 1 is provided with a conductive module 101, the conductive module 101 is a conductor, the conductive module 101 is used to protect the two cable ends 111 after the butt joint is completed, prevent water vapor from entering the contact surface of the two cable ends 111, when the two cable ends 111 are inserted into the conductive module 101 and contact each other, the two cable ends 111 conduct current, the connection shell 1 is slidably connected with two symmetrical sliding rings 2 and two symmetrical limiting rings 3, the two limiting rings 3 are located between the two sliding rings 2, the side of the limiting ring 3 close to the conductive module 101 is threadedly connected with a threaded sleeve 4, the outer side of the threaded sleeve 4 is provided with anti-skid protrusions, which is convenient for the operator to rotate the threaded sleeve 4, the connection shell 1 is provided with an open slot for adjacent threaded sleeves 4 to rotate, which is convenient for the operator to rotate the threaded sleeve 4 from the outside of the connection shell 1, the side of the limiting ring 3 close to the conductive module 101 is fixedly connected with six equidistantly distributed wedge-shaped blocks 5, the wedge-shaped blocks 5 are made of deformable material, the threaded sleeve 4 is used to extrude the adjacent six wedge-shaped blocks 5, so that the six wedge-shaped blocks 5 are close to each other and clamp the adjacent cable ends 111, the spring 6 is fixedly connected between the sliding ring 2 and the adjacent limiting ring 3, after the two cable ends 111 are separated by external force, the spring 6 drives the two cable ends 111 to approach through the limiting ring 3 and the six wedge-shaped blocks 5, so that the two cable ends 111 are tightly attached, the spring 6 resets after the two cable ends 111 are away from each other, so that the two cable ends 111 continue to contact, the connection shell 1 is fixedly connected with two symmetrical positioning rings 7, the positioning ring 7 is located between the adjacent sliding ring 2 and limiting ring 3, the positioning ring 7 is used to limit the adjacent limiting ring 3, the distance between the positioning ring 7 and the adjacent limiting ring 3 is less than the maximum deformation of the spring 6, so as to avoid the compression of the spring 6 exceeding the maximum stroke, resulting in the loss of spring force of the spring 6.

[0021] As shown in Figures 3-5 The left and right sides of the connection shell 1 are provided with two gas storage air bags 8 which are symmetrically distributed upward and downward, the positions close to the gas storage air bags 8 of the connection shell 1 are provided with telescopic air bags 9, the telescopic air bags 9 are used to push the adjacent sliding ring 2, one side of the telescopic air bag 9 close to the adjacent gas storage air bag 8 is fixedly connected with the connection shell 1, one side of the gas storage air bag 8 close to the adjacent telescopic air bag 9 is fixedly connected with the connection shell 1, the left and right sides of the connection shell 1 are provided with two communication holes 102 which are symmetrically distributed upward and downward, the communication hole 102 is used to communicate the adjacent gas storage air bag 8 with the adjacent telescopic air bag 9.

[0022] As shown in Figure 1 And Figures 3-5As shown, the connecting shell 1 near the telescopic air bag 9 is transversely slidably connected with a slide rod 10, the slide rod 10 is slidably connected with the adjacent slide ring 2 and the adjacent positioning ring 7, the connecting shell 1 near the slide rod 10 is longitudinally slidably connected with a sealing rod 11, there is friction between the sealing rod 11 and the connecting shell 1, without external force, the sealing rod 11 cannot move, the side of the sealing rod 11 close to the adjacent slide rod 10 is a rectangular block, the side of the sealing rod 11 away from the adjacent slide rod 10 is a cylindrical rod, in the initial state, the cylindrical rod part of the sealing rod 11 is inserted into the adjacent communication hole 102 and seals it, the cylindrical rod part of the sealing rod 11 is provided with a through hole, the rectangular block part of the sealing rod 11 is provided with a trapezoidal groove, the slide rod 10 moves the adjacent sealing rod 11 by extruding the trapezoidal groove of the adjacent sealing rod 11, so that the through hole of the sealing rod 11 is aligned with and communicated with the adjacent communication hole 102.

[0023] When it is needed to use the connector to connect two cable ends 111, taking the left cable end 111 as an example, the operator inserts the cable end 111 from the left side of the connecting shell 1, the right side of the cable end 111 passes through the limiting ring 3 and enters the conductive module 101, when the right side of the cable end 111 is located in the middle of the conductive module 101, the operator stops moving the cable end 111 to the right, then the operator pushes the threaded sleeve 4 to the left, the threaded sleeve 4 drives the limiting ring 3 to move to the left, the limiting ring 3 drives the slide ring 2 to move to the left through the spring 6, when the slide ring 2 cannot move to the left, the operator continues to move the threaded sleeve 4 to the left, the spring 6 is compressed, the force of the compressed spring 6 ensures that the two cable ends 111 will not be disconnected during normal use, then the operator stops moving the threaded sleeve 4 to the left, the above process is to position the slide ring 2 and the limiting ring 3 (since the slide ring 2 and the limiting ring 3 are free to slide in the connecting shell 1, the slide ring 2 needs to be moved to the left to complete the positioning).

[0024] After the positioning process of the slide ring 2 and the limiting ring 3 is completed, the operator rotates the threaded sleeve 4, the threaded sleeve 4 starts to move to the left, the threaded sleeve 4 extrudes the six wedge-shaped blocks 5 to move closer to each other, since the wedge-shaped blocks 5 are made of deformable steel material, the wedge-shaped blocks 5 will tightly adhere to the cable end 111 after being extruded, when the right side of the cable end 111 is fixed by the slide ring 2, the fixing of the cable end 111 is completed, at the same time, the operator repeats the above steps to fix the right cable end 111, so that the two cable ends 111 contact each other, when the two cable ends 111 are both fixed, the connector works normally, the current of the left cable end 111 is transmitted to the right cable end 111, since the two springs 6 are in a compressed state, the two cable ends 111 will tightly adhere to each other, ensuring the normal transmission of current.

[0025] In the process of the existing connector working, due to the environment (wind blowing) or human reasons (accidentally touching), the two cables are away from each other, so that the two cable ends 111 produce arc, affect the current transmission, when the two cable ends 111 are disconnected, the circuit is disconnected, and the current transmission cannot be completed, therefore, when the cable end 111 slides relative to the connecting shell 1 due to external force, taking the left cable end 111 as an example, the cable end 111 moves to the left, the cable end 111 drives the limiting ring 3 and the threaded sleeve 4 to move to the left through the six wedge blocks 5, the limiting ring 3 makes the spring 6 be compressed, when the external force disappears, the spring 6 resets to drive the limiting ring 3 and the threaded sleeve 4 to move to the right, the limiting ring 3 drives the cable end 111 to move to the right, so that the two cable ends 111 are in contact again, ensuring that the circuit is in a connected state, through the spring 6 and the limiting ring 3, the cable end 111 can still ensure the normal transmission of current after being disturbed by external force, ensuring the smooth operation of the circuit.

[0026] Taking the left limiting ring 3 as an example, in the process of moving the limiting ring 3 to the left, the limiting ring 3 contacts the positioning ring 7 and cannot continue to move to the left due to the limiting of the positioning ring 7, avoiding the compression amount of the spring 6 exceeding the maximum stroke, resulting in the loss of the spring force of the spring 6.

[0027] Under normal circumstances, only the spring force of the spring 6 can make the two cable ends 111 maintain contact, if the cable end 111 moves relative to the adjacent limiting ring 3 due to external force, the working of the connector is as follows, in the initial state, the gas storage air bag 8 is in the inflated state, the sealing rod 11 blocks the adjacent communication hole 102, taking the left cable end 111 as an example, when the cable end 111 drives the limiting ring 3 to move to the left and contact the positioning ring 7, the spring force of the spring 6 reaches the maximum value, at this time, if the cable end 111 continues to move to the left, the extrusion force between the wedge block 5 and the cable end 111 is not enough to fix the cable end 111, therefore, the cable end 111 will move to the left relative to the limiting ring 3, in the process of the limiting ring 3 contacting the positioning ring 7, taking the upper slide rod 10 as an example, the limiting ring 3 extrudes the slide rod 10 to move to the left, the left end of the slide rod 10 drives it to move downward through the trapezoidal groove of the sealing rod 11, so that the through hole of the sealing rod 11 communicates with the communication hole 102, the gas storage air bag 8 communicates with the telescopic air bag 9 through the communication hole 102.

[0028] When the external force is removed, the spring 6 resets the cable end 111 to move to the right through the limiting ring 3, at this time, the distance generated by the spring 6 resetting is not enough to make the two cable ends 111 contact, so in the process of the spring 6 resetting, the gas in the inflated gas storage bag 8 enters the telescopic gas bag 9 through the communication hole 102, the telescopic gas bag 9 gradually extends, the right side of the telescopic gas bag 9 pushes the sliding ring 2 to move to the right, the sliding ring 2 drives the limiting ring 3 to move to the right through the spring 6, thereby making up for the displacement distance of the cable end 111 relative to the limiting ring 3, when the cable end 111 slides relative to the limiting ring 3, the gas in the gas storage bag 8 is supplemented into the telescopic gas bag 9, so that the telescopic gas bag 9 extends, to ensure that the two cable ends 111 continue to contact, and ensure smooth operation of the circuit.

[0029] Embodiment 2

[0030] On the basis of embodiment 1, a waterproof and wet plug type connector for an aviation plug of an intelligent gateway is shown in Figure 3 、 Figure 4 and Figures 6-8 , the connecting shell 1 is provided with transversely equidistantly distributed extrusion blocks 12 near the position of the gas storage bag 8, the extrusion blocks 12 are used for extruding the adjacent gas storage bag 8, the cross section of the extrusion block 12 is arc-shaped, for increasing the contact area between the extrusion block 12 and the gas storage bag 8, the extrusion block 12 extrudes the gas storage bag 8, so that the gas pressure in the gas storage bag 8 increases, the extrusion block 12 is fixedly connected with a guide block 13 which longitudinally limits and slides relative to the connecting shell 1, the connecting shell 1 is provided with two symmetrically distributed sliding grooves on one side near the cable end 111, the side of the guide block 13 away from the adjacent extrusion block 12 is located in the corresponding sliding groove of the connecting shell 1, the sliding groove of the connecting shell 1 is limitingly and slidably connected with a sliding plate 14, the front and rear sides of the sliding plate 14 are provided with guide blocks, for preventing the sliding plate 14 from falling off from the sliding groove of the adjacent connecting shell 1 and guiding the sliding plate 14, the sliding plate 14 is used for extruding the adjacent guide block 13, the side of the guide block 13 away from the adjacent extrusion block 12 is provided with an arc surface, when the sliding plate 14 contacts with the guide block 13, the arc surface of the guide block 13 will be extruded, so that the guide block 13 drives the extrusion block 12 to extrude the gas storage bag 8, the side of the sliding plate 14 near the adjacent gas storage bag 8 is hingedly connected with an intercepting plate 15, the intercepting plate 15 is composed of two symmetrically distributed plates and a cylinder which is rotationally connected with the adjacent sliding plate 14, the hinged position of the intercepting plate 15 and the adjacent sliding plate 14 is provided with a torsion spring for resetting the intercepting plate 15 without external force, the cable end 111 is fixedly connected with a fixed ring 16, the fixed ring 16 is fixedly connected with two symmetrically distributed fixed blocks 17, the fixed blocks 17 slide in the sliding grooves of the adjacent connecting shell 1, the intercepting plate 15 is located in the movement path of the adjacent fixed block 17, the distance between the fixed block 17 and the adjacent intercepting plate 15 is greater than the distance between the limiting ring 3 and the positioning ring 7, when the left limiting ring 3 and the positioning ring 7 contact, the left fixed block 17 has not contacted with the adjacent intercepting plate 15.

[0031] When the cable end 111 is inserted into the conductive module 101, taking the left cable end 111 as an example, the cable end 111 drives the two fixed blocks 17 to move right through the fixed ring 16, taking the upper fixed block 17 as an example, the fixed block 17 moves right along the connecting shell 1 sliding groove, when the fixed block 17 contacts the intercepting plate 15, the fixed block 17 extrudes the intercepting plate 15 to rotate counterclockwise, the torsion spring on the intercepting plate 15 is energized, as shown, when the fixed block 17 moves to the right side of the intercepting plate 15, the torsion spring on the intercepting plate 15 resets to drive the intercepting plate 15 to rotate clockwise and reset, finally the fixed block 17 is located at the right side of the sliding plate 14, and the two cable ends 111 are connected. Figure 7

[0032] In the initial state, the sliding rod 10 is inserted into the trapezoidal groove of the adjacent sealing rod 11, the communication hole 102 is in a communication state, the gas storage air bag 8 is not in an inflated state, but in a normal state, to avoid the situation that the gas storage air bag 8 is in an inflated state for a long time (the air bag leakage is generally slow leakage, which releases gas in a long time), and the embodiment 2 is an optimization of the embodiment 1, taking the left cable end 111 as an example, when the cable end 111 does not relatively slide with respect to the limiting ring 3, and the cable is disturbed by external force, the cable end 111 drives the fixed ring 16 to move left, the fixed ring 16 drives the two fixed blocks 17 to move left, but the fixed block 17 does not contact the intercepting plate 15, when the external force disappears, the spring 6 resets to drive the wedge block 5 through the limiting ring 3 to make the cable end 111 move right, the cable end 111 drives the two fixed blocks 17 to move right through the fixed ring 16, when the cable end 111 relatively slides with respect to the limiting ring 3, taking the upper fixed block 17 as an example, after the limiting ring 3 contacts the positioning ring 7, the fixed block 17 contacts the intercepting plate 15, then the cable end 111 moves left with respect to the limiting ring 3, the fixed block 17 drives the intercepting plate 15 to move left, the intercepting plate 15 drives the sliding plate 14 to move left, the sliding plate 14 extrudes the rightmost guide block 13 upward after contacting the guide block 13, the guide block 13 drives the sliding plate 14 to move upward, the sliding plate 14 extrudes the gas storage air bag 8, and the gas pressure in the gas storage air bag 8 and the telescopic air bag 9 increases.

[0033] ​With the cable end 111 constantly moving left relative to the limit ring 3, the sliding plate 14 will be pressed from right to left in turn, the air pressure in the gas storage bag 8 and the telescopic bag 9 gradually increases, and the right side of the several guide blocks 13 is pressed by the sliding plate 14. When the external force disappears, the spring 6 resets to drive the cable end 111 to move right through the limit ring 3 and the six wedge-shaped blocks 5, the cable end 111 drives the fixed block 17 to move right through the fixed ring 16, the fixed block 17 gradually moves away from the intercepting plate 15, the position of the intercepting plate 15 remains unchanged, and the intercepting plate 15 always presses the right side of the several guide blocks 13. During the resetting process of the spring 6, the pressure in the gas storage bag 8 and the telescopic bag 9 is released, so that the right side of the telescopic bag 9 moves right to push the sliding ring 2 to move right, the sliding ring 2 drives the limit ring 3 to move right through the spring 6, and the distance difference caused by the relative sliding of the cable end 111 and the limit ring 3 is compensated.

[0034] When the cable end 111 again relatively slides relative to the limit ring 3, the left side of the guide block 13 that is not pressed will be pressed, thereby continuing to compensate for the distance difference caused by the relative sliding of the cable end 111 and the limit ring 3. The connector can press the guide block 13 to press the gas storage bag 8 through the pressing block 12, increase the air pressure in the gas storage bag 8 and the telescopic bag 9, and reset the cable end 111 when the cable end 111 and the limit ring 3 relatively slide multiple times. The problem that the cable end 111 cannot be reset due to air leakage of the gas storage bag 8 is avoided (since the air leakage process is slow, the air pressure in the gas storage bag 8 will not increase in a short time, and the pressure release process will not occur), the application range of the connector is improved, and the operator can install a pressure sensor on the arc surface of the guide block 13 away from the conductive module 101. When the pressure sensor is triggered, the whole proves that all the guide blocks 13 are pressed, and the operator determines the position of the connector and repairs it through the pressure sensor.

[0035] Although embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that changes can be made to these embodiments without departing from the principles and spirit of the present application.
