Abstract
Description
Technical Field
[0001] This utility model relates to the field of data transmission lines, and in particular to an aviation plug data transmission line. Background Technology
[0002] Aviation connectors, with their excellent electrical performance and mechanical stability, are widely used in various fields such as industrial automation, rail transportation, and communication base stations. In industrial automation production lines, equipment operates under high loads for extended periods, requiring frequent plugging and unplugging of aviation connectors, which can easily cause scratches on the outer casing and deformation of the internal pins. In the rail transportation sector, the continuous vibrations generated by train operation can gradually loosen the connector sockets, affecting signal transmission stability. Communication base stations operate in complex outdoor environments, and aviation connectors are subjected to wind, rain, and drastic temperature and humidity changes over long periods, making them highly susceptible to corrosion and leading to electrical connection failures.
[0003] Some protective devices only protect against a single factor, making them inadequate for complex and ever-changing application environments. While some protective designs offer good protection, they increase the size of the plug after installation, affecting the overall layout of the equipment, and the installation and disassembly procedures are cumbersome, increasing maintenance costs and time. Utility Model Content
[0004] To reduce the exposure of aviation plugs to the external environment after plugging in, this utility model provides an aviation plug data transmission cable.
[0005] This utility model provides a technical solution that adopts the following approach:
[0006] An aviation connector data transmission cable includes a connector portion and a cable body portion. The connector portion is used to insert into an external connector, and the cable body portion is used to connect the connector portion and the desired connected machine. A protective sleeve is slidably connected to the outer periphery of the connector portion. The protective sleeve is an insulating sleeve. An elastic element for resetting is provided between the protective sleeve and the connector portion. The front end of the connector portion is a metal end, and the protective sleeve surrounds the periphery of the metal end. When the protective sleeve slides toward the cable body portion, the protective sleeve and the metal end are misaligned. The elastic force of the elastic element is much smaller than the clamping force between the connector portion and the connector.
[0007] The protective sleeve is slid to expose the metal end. The plug is then aligned with the external socket and inserted, ensuring a tight connection between the plug and the socket. This method of plugging into the external environment and abutting against it is existing technology and will not be elaborated upon here. Because the elastic force is less than the frictional force of the contact, the outer periphery of the socket pushes open the protective sleeve, allowing the plug to be securely exposed within the sleeve, facilitating insertion into the socket. When the plug is removed, the protective sleeve automatically springs back and re-encloses the outer periphery of the metal end. Furthermore, the protective sleeve can be adjusted according to the insertion depth of the plug, ensuring a close fit to the outer periphery of the socket, thereby reducing the length of the metal end exposed after insertion and better protecting the metal end.
[0008] Preferably, the plug portion is further provided with a limiting member for securing the protective sleeve.
[0009] The retaining component secures the protective sleeve, preventing it from wobbling around the metal end and ensuring it firmly surrounds the metal end, reducing the chance of the metal end being exposed.
[0010] Preferably, the limiting member is a metal spring sheet provided on both sides of the plug portion. The metal spring sheet is bent to form two guide surfaces extending along the length direction of the plug portion. The two guide surfaces extend from the side wall of the plug portion toward each other. The inner side wall of the protective sleeve is provided with a limiting hole adapted to the metal spring sheet. When the metal spring sheet is located in the limiting hole, the end of the protective sleeve is flush with the end of the metal end.
[0011] When the sliding protective sleeve is misaligned with the metal end, the metal spring is pressed and deformed, causing the limiting hole and the metal spring to misalign. The movement of the limiting component on the protective sleeve can be directly released by moving the protective sleeve, without additional operation of the limiting component. When the elastic component springs the protective sleeve back until the metal spring slides back into the limiting hole, no external force is applied to the protective sleeve. Therefore, the limiting component can be firmly inserted back into the limiting hole of the protective sleeve and no longer deform, thus firmly limiting the movement of the protective sleeve in the length direction of the plug. Furthermore, there are two metal springs, which limit the movement of the protective sleeve in the width direction of the plug from both sides of the plug.
[0012] Preferably, the inner peripheral wall of the protective sleeve fits against the outer peripheral wall of the plug portion, the inner peripheral wall of the protective sleeve is provided with a support block, the support block is connected to a guide rod, the plug portion has a sliding hole for the guide rod to slide into, and the elastic element is provided in the sliding hole and fixedly connected to the bottom of the guide rod.
[0013] The protective sleeve and the outer wall of the plug form a mutually restrictive guiding fit, allowing the protective sleeve to slide along the length of the plug. The fit between the guide rod and the sliding hole makes the connection between the protective sleeve and the plug tighter, and makes the protective sleeve more stable and less prone to shaking when sliding along the plug.
[0014] Preferably, the elastic element is a spring.
[0015] Preferably, a limiting block is also connected between the guide rod and the spring.
[0016] The limiting block restricts the spring from sliding out of the sliding hole, which helps to improve the overall installation stability of the line.
[0017] In summary, this utility model has the following beneficial technical effects:
[0018] The protective sleeve is slid to expose the metal end. The plug is then aligned with the external socket and inserted, ensuring a tight connection between the plug and the socket. This method of plugging into the external environment and abutting against it is existing technology and will not be elaborated upon here. Because the elastic force is less than the frictional force of the contact, the outer periphery of the socket pushes open the protective sleeve, allowing the plug to be securely exposed within the sleeve, facilitating insertion into the socket. When the plug is removed, the protective sleeve automatically springs back and re-encloses the outer periphery of the metal end. Furthermore, the protective sleeve can be adjusted according to the insertion depth of the plug, ensuring a close fit to the outer periphery of the socket, thereby reducing the length of the metal end exposed after insertion and better protecting the metal end.

[0022] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.
[0023] This utility model discloses an aviation plug data transmission line.
[0024] Reference Figure 1 as well as Figure 2An aviation plug data transmission line includes a plug part 1 and a wire part 2. The plug part 1 is used to plug into an external socket, and the wire part 2 is used to connect the plug part 1 and the machine to be connected. A protective sleeve 3 is slidably connected to the outer periphery of the plug part 1. The protective sleeve 3 is an insulating sleeve. An elastic element 4 for resetting is provided between the protective sleeve 3 and the plug part 1. The front end of the plug part 1 is a metal end 5. The protective sleeve 3 surrounds the metal end 5. When the protective sleeve 3 slides toward the wire part 2, the protective sleeve 3 and the metal end 5 are misaligned. The elastic force of the elastic element 4 is much less than the clamping force between the plug part 1 and the socket.
[0025] The protective sleeve 3 is slid to expose the metal end 5. The plug part 1 is then aligned with the external socket and inserted, ensuring a tight connection between the plug part 1 and the socket. This method of plugging into the external environment and abutting against it is existing technology and will not be elaborated upon here. Because the elastic force is less than the frictional force of the abutment, the outer periphery of the socket pushes open the protective sleeve 3, allowing the plug part 1 to be securely exposed within the protective sleeve 3, facilitating insertion into the socket. When the plug part 1 is pulled out, the protective sleeve 3 automatically springs back and re-encloses the outer periphery of the metal end 5. Simultaneously, the protective sleeve 3 can be adjusted according to the insertion depth of the plug part 1, ensuring the protective sleeve 3 fits snugly against the outer periphery of the socket, thereby reducing the length of the metal end 5 exposed after insertion and better protecting the metal end 5.
[0026] Reference Figure 1 as well as Figure 2 In this embodiment, the plug portion 1 is also provided with a limiting member for securing the protective sleeve 3.
[0027] The limiting component secures the protective sleeve 3, making it less likely for the protective sleeve 3 to shake around the metal end 5, thus ensuring that the protective sleeve 3 firmly surrounds the metal end 5 and reducing the possibility of the metal end 5 being exposed.
[0028] Reference Figure 1 as well as Figure 2 In this embodiment, the limiting member is a metal spring 6 provided on both sides of the plug portion 1. The metal spring 6 is bent to form two guide surfaces extending along the length direction of the plug portion 1. The two guide surfaces extend from the side wall of the plug portion 1 toward each other. The inner side wall of the protective sleeve 3 is provided with a limiting hole 7 that is adapted to the metal spring 6. When the metal spring 6 is located in the limiting hole 7, the end of the protective sleeve 3 is flush with the end of the metal end 5.
[0029] When the sliding protective sleeve 3 is misaligned with the metal end 5, the metal spring 6 is pressed and deformed, causing the limiting hole 7 to misalign with the metal spring 6. The movement of the limiting member on the protective sleeve 3 can be directly released by the movement of the protective sleeve 3 without additional operation of the limiting member. When the elastic member 4 springs the protective sleeve 3 back until the metal spring 6 slides back into the limiting hole 7, no external force is applied to the protective sleeve 3. Therefore, the limiting member can be firmly inserted back into the limiting hole 7 of the protective sleeve 3 and no longer deform, thus firmly limiting the movement of the protective sleeve 3 in the length direction of the plug part 1. There are two metal springs 6, which limit the movement of the protective sleeve 3 from both sides of the plug part 1, thereby limiting the movement of the protective sleeve 3 in the width direction of the plug part 1.
[0030] Reference Figure 1 as well as Figure 2 In this embodiment, the inner peripheral wall of the protective sleeve 3 fits against the outer peripheral wall of the plug part 1. The inner peripheral wall of the protective sleeve 3 is provided with a support block 8, and the support block 8 is connected to a guide rod 9. The plug part 1 has a sliding hole 11 for the guide rod 9 to slide in. The elastic element 4 is provided in the sliding hole 11 and is fixedly connected to the bottom of the guide rod 9.
[0031] The protective sleeve 3 and the outer wall of the plug part 1 form a mutually restrictive guiding fit, which allows the protective sleeve 3 to slide along the length direction of the plug part 1. The cooperation between the guide rod 9 and the sliding hole 11 makes the connection between the protective sleeve 3 and the plug part 1 tighter, and makes the protective sleeve 3 more stable and less prone to shaking when sliding along the plug part 1.
[0032] Reference Figure 1 as well as Figure 2 In this embodiment, the elastic element 4 is a spring.
[0033] Reference Figure 1 as well as Figure 2 In this embodiment, a limiting block 10 is also connected between the guide rod 9 and the spring.
[0034] The limiting block 10 restricts the spring from sliding out of the sliding hole 11, which helps to improve the overall installation stability of the line.
[0035] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
