Description

Technical Field

[0001] This utility model relates to the field of grounding connector technology, and in particular to temporary grounding sockets, temporary grounding plugs, temporary grounding connectors, and aircraft.

[0002] Background technology.

[0003] The importance of temporary grounding sockets for aircraft and other flying devices cannot be overlooked. These sockets not only eliminate static electricity buildup and prevent potential safety hazards, but also protect the electronic equipment of aircraft and other flying devices from current surges and electromagnetic interference. In practical applications, whether for routine maintenance or special mission preparation, grounding sockets provide reliable safety assurance for aircraft and other flying devices. Therefore, the proper configuration and correct use of grounding sockets are of profound significance for improving the safety and efficiency of aviation operations. This is not only about protecting the aircraft itself, but also about demonstrating a high degree of responsibility for the lives of pilots and passengers.

[0004] However, in certain special circumstances, such as emergency takeoff or other unforeseen situations, if the grounding cable used for temporary grounding fails to disconnect in time, it may threaten the safe operation of aircraft and other flying vehicles. Therefore, designing a grounding connector with a "self-detaching" function is particularly important. Existing grounding connectors are usually installed on the airframe structure with screws, which is cumbersome to install and remove, and if the pilot or ground crew does not remove the grounding socket during takeoff, it can easily damage the airframe structure. Existing self-detaching connectors mainly include two types: mechanical separation and electromagnetic separation. Mechanical separation connects the plug to the ground through a separation cable, requiring the use of an additional cable; electromagnetic separation controls the detachment by controlling the voltage, which is not suitable for grounding sockets.

[0005] Therefore, there is an urgent need for a new type of temporary grounding connector that can detach itself without damage when the aircraft takes off and does not actively disconnect the connection.

[0006] It should be noted that the above technical information is intended only to enhance the understanding of the overall background technology of this utility model, and should not be regarded as an admission or in any form implying that the above technical information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] To address the shortcomings in the aforementioned background technology, this utility model proposes a temporary grounding socket, a temporary grounding plug, and a temporary grounding connector. The technical problem to be solved is: how to achieve automatic separation without damage when the aircraft takes off and does not actively disconnect the grounding connection.

[0008] The technical solution of this utility model is as follows:

[0009] A temporary grounding socket includes a grounding base with a magnetic conductor disposed thereon. The conductor is used for magnetically attracting a temporary grounding plug and the grounding base, and for electrically connecting the temporary grounding plug and the grounding base. This technical solution provides a magnetically attracted temporary grounding socket, where the grounding base can serve as the main structure for direct connection to aircraft such as airplanes, serving both for electrostatic transfer and for installing and protecting the conductor. The conductor, as a functional component providing magnetic attraction, facilitates the magnetic attraction between the temporary grounding plug and the device, and also allows for easy detachment of the device from the temporary grounding plug under external force. It should be noted that the above description is only one method of using the temporary grounding socket. Those skilled in the art can employ the opposite application method; for example, using the temporary grounding plug as a component directly connected to aircraft such as airplanes, and the device as a directly grounded component, can also achieve convenient assembly and automatic passive detachment of the temporary grounding socket and the temporary grounding plug.

[0010] Based on the above technical solutions, as a preferred technical solution for the temporary grounding socket, the conductor includes an internal strong magnet and a surface conductive layer. This technical solution provides a preferred structural form for the conductor, namely a composite functional structure. The internal strong magnet serves as the magnetic functional structure, and the external conductive layer serves as the conductive functional structure. The conductive layer provides physical protection for the internal strong magnet and prevents demagnetization. Regarding the manufacturing process of the conductive layer, various options are available, such as electroplating, thermal spraying, vacuum evaporation, sputtering, or ion plating to form a metal layer. Those skilled in the art can select the appropriate process type based on the specific circumstances.

[0011] Based on the above technical solutions, as a preferred technical solution for the temporary grounding socket, the grounding base is provided with a positioning hole for fitting a positioning pin of the temporary grounding plug. Alternatively, the grounding base is provided with a positioning pin for fitting a positioning hole on the temporary grounding plug. This technical solution adds a more reliable connection structure to the magnetic adsorption, namely, a pin-hole positioning structure is added between the temporary grounding socket and the temporary grounding plug, which can prevent radial relative displacement between the two. It should be noted that the above description is only one structural method of the positioning structure. Those skilled in the art can use the opposite application method, for example, providing a positioning hole on the temporary grounding plug and a matching positioning pin on the grounding base.

[0012] Based on the above technical solutions, as a preferred technical solution for the temporary grounding socket, the grounding base has a stepped hole, and the conductor is a stepped columnar structure that fits into the stepped hole. The conductor and the stepped hole are connected by conductive adhesive, welding, or interference fit. This technical solution not only provides a preferred structural form for the grounding base but also a preferred structural form for the conductor, and a preferred assembly structure relationship between the two. The stepped hole of the grounding base can both accommodate and position the stepped columnar conductor. With the help of the mounting surface of the grounding base, the conductor can be firmly fixed inside. When the conductor is connected to the stepped hole of the grounding base by conductive adhesive, the conductor can be easily removed from the stepped hole after the grounding base is removed from the mounting surface. When the conductor is welded or interference fits the stepped hole of the grounding base, the reliability of the connection between the two can be further guaranteed.

[0013] A temporary grounding plug includes a grounding head with a magnetic conductor second thereon. The conductor second is used for magnetically attracting a temporary grounding socket and the grounding head, and for electrically connecting the temporary grounding socket and the grounding head. This technical solution provides a magnetically attracted temporary grounding plug, where the grounding head can serve as the main structure for direct connection with aircraft or other flying vehicles, serving both for electrostatic transfer and for installing and protecting the conductor second. The conductor second, as a functional component providing magnetic attraction, facilitates the magnetic attraction between the temporary grounding socket and the device, and also allows for easy detachment of the device from the temporary grounding socket under external force. It should be noted that the above description is only one way of using the temporary grounding plug. Those skilled in the art can use the opposite application method. For example, the temporary grounding socket can be used as a component directly connected to aircraft or other flying vehicles, while the device can be used as a directly grounded component, achieving the same convenient assembly and automatic passive detachment of the temporary grounding socket and the temporary grounding plug.

[0014] Based on the above technical solutions, as a preferred technical solution for the temporary grounding plug, the conductor two includes an internal strong magnet and a surface conductive layer. This technical solution provides a preferred structural form for the conductor two, namely a composite functional structure. The internal strong magnet serves as the magnetic functional structure, and the external conductive layer serves as the conductive functional structure. The conductive layer provides physical protection for the internal strong magnet and prevents demagnetization. Regarding the manufacturing process of the conductive layer two, various options are available, such as electroplating, thermal spraying, vacuum evaporation, sputtering, or ion plating to form a metal layer. Those skilled in the art can select the appropriate process type based on the specific circumstances.

[0015] Based on the above technical solutions, as a preferred technical solution for the temporary grounding plug, the grounding head has a stepped grounding head hole, and the second conductor is a stepped columnar structure that fits into the stepped grounding head hole. The second conductor and the stepped grounding head hole are connected by conductive adhesive, welding, or interference fit. This technical solution not only provides a preferred structural form for the grounding head, but also a preferred structural form for the second conductor, and a preferred assembly structure relationship between the two. The stepped grounding head hole can both accommodate and position the stepped columnar conductor. With the help of the mounting surface of the grounding base, the second conductor can be firmly fixed inside. When the second conductor and the stepped grounding head hole are connected by conductive adhesive, the second conductor can be easily removed from the stepped grounding head hole after the grounding base is removed from the mounting surface. When the second conductor and the stepped grounding head hole are welded or interference fit, the reliability of the connection between the two can be further guaranteed.

[0016] Based on the above technical solutions, as a preferred technical solution for the temporary grounding plug, the grounding head is connected to a terminal, which is used to abut against the second conductor and is threaded, welded, or crimped to the grounding head. This technical solution provides a more preferred assembly relationship between the grounding head and the second conductor, and is particularly suitable for temporary grounding plugs to be directly grounded through terminals and grounding wires connected to the terminals, while temporary grounding sockets are used to be directly connected to aircraft such as airplanes. One end of the terminal is used to connect to the grounding wire, and the other end is used to connect to the grounding head. At the same time, the end connected to the grounding head is also used to press and position the second conductor. If the terminal is threaded to the grounding head, the various components can be easily assembled and disassembled.

[0017] A temporary grounding connector includes a temporary grounding socket as described in any of the above technical solutions, the temporary grounding socket being adapted to a temporary grounding plug as described in any of the above technical solutions.

[0018] An aircraft includes a temporary grounding socket as described in any of the above technical solutions, the temporary grounding socket being adapted to a temporary grounding plug as described in any of the above technical solutions; when the temporary grounding plug is grounded through a grounding wire, the temporary grounding socket is connected to the aircraft; when the temporary grounding socket is grounded through a grounding wire, the temporary grounding plug is connected to the aircraft.

[0019] Compared with existing technologies, this utility model not only provides a novel temporary grounding socket, but also a novel temporary grounding plug, a novel temporary grounding connector, and an aircraft. Its core lies in the use of a magnetic adapter method. While the temporary grounding socket and the temporary grounding plug are magnetically attached via magnetic conductor one and / or conductor two, the grounding line is also connected through conductor one and / or conductor two, thereby enabling temporary grounding of aircraft and other aircraft. Even when the aircraft takes off and the connection is not actively disconnected, the connection is automatically and without damage. This utility model is not only simple in structure, but also easy to install, convenient to use, and quick to replace, and can be used for temporary grounding of various aircraft and other aircraft when they are parked on the ground. The core innovation of this utility model is: simple structure, convenient installation, self-detachment, and suitability for applications where the temporary grounding is not disconnected during aircraft takeoff.

It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0050] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0051] A temporary grounding socket, such as Figure 1 and Figure 2As shown, the device includes a grounding base 2, on which a magnetic conductor 21 is disposed. The conductor 21 is used to magnetically attract the temporary grounding plug and the grounding base 2 and to electrically connect the temporary grounding plug and the grounding base 2. That is, the conductor 21 has both magnetic attraction function and conductive function.

[0052] When the temporary grounding socket is not assembled with the temporary grounding plug, the conductor 21 is magnetically attracted to the grounding base 2. At the same time, the conductor 21 and the grounding base 2 form a conductive equipotential body, and the potential difference between any two points inside and on the surface is zero, that is, the potential is equal everywhere.

[0053] When the temporary grounding socket and the temporary grounding plug are assembled, the conductor 21 is magnetically attracted to the grounding base 2, and at the same time, it is also magnetically attracted to the temporary grounding plug, so that the temporary grounding socket and the temporary grounding plug are reliably connected. At this time, the grounding base 2 and the temporary grounding plug are electrically connected, and current or static electricity can be transmitted, thereby transmitting static electricity or current to the grounding terminal.

[0054] It should be noted that the temporary grounding socket provided in this embodiment has multiple application forms. One is that the temporary grounding socket is connected to the surface of various aircraft such as airplanes, and is compatible with a directly grounded temporary grounding plug. That is, the temporary grounding plug is fixed to the ground via the grounding wire 5, while the temporary grounding socket is integrated with the movable aircraft or other aircraft. Another is that the temporary grounding socket is fixed to the ground via the grounding wire 5, and the temporary grounding plug is integrated with the movable aircraft or other aircraft. In addition, the temporary grounding socket or temporary grounding plug can also be applied to other devices that require the elimination of static electricity or current transmission, such as fixed power supply devices, or other devices that are prone to generating static electricity.

[0055] Preferably, when the temporary grounding socket is connected to the surface of an aircraft or other aircraft, a mounting hole for disassembly is provided on the grounding base 2, so that the grounding base 2 is connected to the movable aircraft or other aircraft by means of screws or rivets. Of course, various connection methods such as welding, bonding, and snap-fit ​​can also be used to connect the temporary grounding socket to the surface of the aircraft or other aircraft.

[0056] In summary, this embodiment provides a magnetic temporary grounding socket, wherein the grounding base 2 can serve as the main structure for direct connection with aircraft and other flying vehicles, serving both for electrostatic transfer and for installing and protecting the conductor 21; the conductor 21 serves as a functional component that provides magnetic attraction force, which can conveniently achieve magnetic attraction between the temporary grounding plug and this device, and can also conveniently detach this device from the temporary grounding plug under the action of external force.

[0057] It should be noted that the above description is only one way of using the temporary grounding socket. Those skilled in the art can use the opposite application method. For example, the temporary grounding plug can be used as a component directly connected to aircraft or other flying vehicles, while this device can be used as a component directly grounded. This can also achieve convenient assembly and automatic passive disconnection of the temporary grounding socket and the temporary grounding plug.

[0058] Based on the above embodiments, as a preferred embodiment of the temporary grounding socket, such as... Figures 5 to 7 As shown, the conductor 21 includes a strong magnet 211 located inside and a conductive layer 212 located on the surface. The specific types of the strong magnet 211 and the conductive layer 212 are not limited in this embodiment, as long as the purpose of the invention can be achieved.

[0059] It should be noted that, based on the technical guidance of the inventive concept of this embodiment, those skilled in the art can choose suitable existing materials as the strong magnet 211, such as neodymium iron boron magnets, alnico magnets, samarium cobalt magnets, etc. Neodymium iron boron magnets: currently the highest-performing commercially available magnets, with a maximum magnetic energy product more than 10 times that of ferrite magnets, and an operating temperature up to 200℃. Alnico magnets: withstand temperatures above 600℃, but are relatively expensive. Samarium cobalt magnets: suitable for high-temperature environments of 250-350℃, but have high material costs. Ferrite magnets: withstand temperatures up to 250℃ and are low-cost.

[0060] Those skilled in the art can also choose suitable existing materials as the conductive layer 212, such as low-melting-point metals like aluminum and silver vacuum-deposited, or various conductive oxide films formed by electroplating, etc. Vacuum evaporation: Materials are evaporated in a vacuum environment by heating or electron beam bombardment, and gaseous atoms are deposited on the substrate surface. This method is suitable for plating low-melting-point metals such as aluminum and silver. Sputtering: Sputtering atoms are deposited by bombarding a target with ions. This method is suitable for high-melting-point materials such as titanium and chromium, and provides strong film-substrate adhesion. Ion plating: Ion bombardment enhances the density of the film layer, resulting in better corrosion resistance than ordinary PVD films. Thermal spraying: Materials are melted at high temperatures and sprayed onto the substrate surface. This method is suitable for repair or wear-resistant coatings. Anodizing: An oxide film is formed on the surface during electrolysis, enhancing corrosion resistance.

[0061] This embodiment provides a preferred structural form of the conductor 21, namely a composite functional structure. The internal strong magnet 211 serves as the magnetic functional structure, and the external conductive layer 212 serves as the conductive functional structure. The conductive layer 212 can provide physical protection for the internal strong magnet 211 and prevent the strong magnet 211 from being demagnetized. As for the manufacturing process of the conductive layer 212, there are various options, such as forming a metal layer through electroplating, thermal spraying, vacuum evaporation, sputtering, or ion plating. Those skilled in the art can select the appropriate process type based on the actual situation.

[0062] Based on the above embodiments, as a preferred embodiment of the temporary grounding socket, such as... Figure 2 As shown, the grounding base 2 is provided with a positioning hole 22, which is used to fit the positioning pin 31 of the temporary grounding plug. Alternatively, the grounding base 2 is provided with a positioning pin, which is used to fit the positioning hole on the temporary grounding plug.

[0063] The shape of the positioning hole 22 can be selected in various ways, such as a round hole, a semi-circular hole, an elliptical hole, etc. Those skilled in the art can select a positioning hole of various shapes suitable for practical use according to the technical guidance of this embodiment. It should be noted that, regardless of the shape of the positioning hole selected, it is necessary to ensure that after the positioning pin and the positioning hole are assembled, the relative position between the grounding seat 2 and the temporary grounding plug can only be limited in the radial direction, while in the axial direction, it is preferable to allow the two to disengage from each other.

[0064] Regarding the number and specific distribution of the positioning holes 22, those skilled in the art can choose a suitable practical embodiment based on the technical guidance of this embodiment, such as providing only one positioning hole, two positioning holes, or more positioning holes. When multiple positioning holes are arranged, they can be randomly distributed or regularly distributed, such as equidistantly distributed around the central axis of the grounding seat 2, or evenly spaced along any direction, etc. It should be noted that, regardless of the number of positioning holes used or how they are distributed, it is necessary to ensure that after the positioning pin and the positioning hole are assembled, the relative position between the grounding seat 2 and the temporary grounding plug can only be limited in the radial direction, while in the axial direction, it is preferable to allow them to disengage from each other.

[0065] This embodiment, based on magnetic adsorption, adds a more reliable connection structure. Specifically, a pin and hole positioning structure is added between the temporary grounding socket and the temporary grounding plug to prevent radial relative displacement between them. It should be noted that the above description is only one possible positioning structure. Those skilled in the art can employ the opposite method, for example, providing a positioning hole on the temporary grounding plug and a matching positioning pin on the grounding base 2.

[0066] Based on the above embodiments, as a preferred embodiment of the temporary grounding socket, such as... Figure 4 As shown, the grounding base 2 has a stepped grounding base hole 23, as... Figure 5 As shown, the conductor 21 is a stepped columnar structure that is inserted into the stepped hole 23 of the grounding seat.

[0067] This embodiment not only provides a preferred structural form of the grounding base 2, but also a preferred structural form of the conductor 21, and a preferred assembly structure relationship between the two. The stepped hole 23 of the grounding base can both accommodate the stepped columnar conductor 21 and position the stepped columnar conductor 21. With the help of the mounting surface of the grounding base 2, the conductor 21 can be firmly fixed inside.

[0068] The conductor 21 is connected to the stepped hole 23 of the grounding base via conductive adhesive, welding, or interference fit. When the conductor 21 is connected to the stepped hole 23 of the grounding base via conductive adhesive, the conductor 21 can be easily removed from the stepped hole 23 of the grounding base after the grounding base 2 is removed from the mounting surface. When the conductor 21 is connected to the stepped hole 23 of the grounding base via welding or interference fit, the reliability of the connection between the two can be further guaranteed.

[0069] Preferably, such as Figure 4 As shown, the grounding base 2 has a rectangular parallelepiped structure with rounded corners, and a stepped hole 23 at the center. Mounting holes 24 are provided at the four corners of the grounding base 2, and mounting screws 25 are fitted into these holes. The grounding base 2 can be connected to the aircraft 1 using the mounting screws 25.

[0070] Preferably, after the conductor 21 is assembled with the stepped hole 23 of the grounding base, the small diameter section of the conductor 21 is adapted to the small diameter hole at the outer end of the stepped hole 23 of the grounding base, and the large diameter section of the conductor 21 is adapted to the large diameter hole at the inner end of the stepped hole 23 of the grounding base. The outer end face of the conductor 21 is flush with the outer end face of the grounding base 2. When the temporary grounding plug is assembled with the temporary grounding socket, the outer end face of the grounding base 2 and the outer end face of the conductor 21 simultaneously contact the temporary grounding plug.

[0071] A temporary grounding plug, such as Figure 1 and Figure 2 As shown, the device includes a grounding head 3, on which a magnetic conductor 32 is mounted. The conductor 32 is used for magnetic adsorption of the temporary grounding socket and the grounding head 3, and also for electrical connection between the temporary grounding socket and the grounding head 3. That is, the conductor 32 has both magnetic adsorption and conductive properties.

[0072] When the temporary grounding socket is not assembled with the temporary grounding plug, the conductor 2 32 is magnetically attracted to the grounding head 3. At the same time, the conductor 2 32 and the grounding head 3 form a conductive equipotential body, and the potential difference between any two points inside and on the surface is zero, that is, the potential is equal everywhere.

[0073] When the temporary grounding socket and the temporary grounding plug are assembled, the conductor 32 is magnetically attracted to the grounding head 3, and at the same time, it is also magnetically attracted to the temporary grounding socket, so that the temporary grounding socket and the temporary grounding plug are reliably connected. At this time, the grounding head 3 and the temporary grounding socket are electrically connected, and current or static electricity can be transmitted, thereby transmitting static electricity or current to the grounding end.

[0074] It should be noted that the temporary grounding plug provided in this embodiment has multiple application forms. One is that the temporary grounding plug is connected to the surface of various aircraft such as airplanes, and is compatible with a directly grounded temporary grounding socket. That is, the temporary grounding socket is fixed to the ground via the grounding wire 5, while the temporary grounding plug is integrated with the movable aircraft or other aircraft. Another is that the temporary grounding plug is fixed to the ground via the grounding wire 5, and the temporary grounding socket is integrated with the movable aircraft or other aircraft. In addition, the temporary grounding socket or temporary grounding plug can also be applied to other devices that require the elimination of static electricity or current transmission, such as fixed power supply devices, or other devices that are prone to generating static electricity.

[0075] Preferably, when the temporary grounding plug is connected to the surface of an aircraft or other aircraft, a mounting hole for disassembly is provided on the grounding head 3, so that the grounding head 3 is connected to the movable aircraft or other aircraft as a whole by means of screws or rivets. Of course, various connection methods such as welding, bonding, and snap-fit ​​can also be used to connect the temporary grounding plug to the surface of the aircraft or other aircraft.

[0076] In summary, this embodiment provides a magnetic temporary grounding plug. The grounding head 3 can serve as the main structure for direct connection to aircraft such as airplanes, serving both as electrostatic transfer and for installing and protecting the conductive body 32. The conductive body 32, as a functional component providing magnetic attraction, facilitates the magnetic attraction between the temporary grounding socket and the device, and also allows for easy detachment of the device from the temporary grounding socket under external force. It should be noted that the above description is only one method of using the temporary grounding plug. Those skilled in the art can employ the opposite application method. For example, the temporary grounding socket can be used as a component directly connected to aircraft such as airplanes, while the device can be used as a directly grounded component, achieving both convenient assembly and automatic passive detachment of the temporary grounding socket and plug.

[0077] Based on the above embodiments, as a preferred embodiment of the temporary grounding plug, such as... Figures 9 to 11 As shown, the conductor 32 includes a strong magnet 321 located inside and a conductive layer 322 located on the surface. The specific types of the strong magnet 321 and the conductive layer 322 are not limited in this embodiment, as long as the purpose of the invention can be achieved.

[0078] It should be noted that, based on the technical guidance of the inventive concept of this embodiment, those skilled in the art can choose suitable existing materials as the strong magnet 321, such as neodymium iron boron magnets, alnico magnets, samarium cobalt magnets, etc. Neodymium iron boron magnets: currently the highest-performing commercially available magnets, with a maximum magnetic energy product more than 10 times that of ferrite magnets, and an operating temperature up to 200℃. Alnico magnets: withstand temperatures above 600℃, but are relatively expensive. Samarium cobalt magnets: suitable for high-temperature environments of 250-350℃, but have high material costs. Ferrite magnets: withstand temperatures up to 250℃ and are low-cost.

[0079] Those skilled in the art can also choose suitable existing materials as the conductive layer 322, such as low-melting-point metals like aluminum and silver deposited by vacuum evaporation, or various conductive oxide films formed by electroplating, etc. Vacuum evaporation: Materials are evaporated in a vacuum environment by heating or electron beam bombardment, and gaseous atoms are deposited on the substrate surface. This method is suitable for depositing low-melting-point metals such as aluminum and silver. Sputtering: Sputtering atoms are deposited by bombarding a target with ions. This method is suitable for high-melting-point materials such as titanium and chromium, and results in strong film-substrate adhesion. Ion plating: Ion bombardment enhances the density of the film layer, resulting in better corrosion resistance than ordinary PVD films. Thermal spraying: Materials are melted at high temperatures and sprayed onto the substrate surface. This method is suitable for repair or wear-resistant coatings. Anodizing: An oxide film is formed on the surface during electrolysis, enhancing corrosion resistance.

[0080] This embodiment provides a preferred structural form of the conductor 32, namely a composite functional structure. The internal strong magnet 321 serves as a magnetic functional structure, and the external conductive layer 322 serves as a conductive functional structure. The conductive layer 322 can provide physical protection for the internal strong magnet 321 and prevent the strong magnet 321 from being demagnetized.

[0081] As for the fabrication process of conductive layer 322, there are various options, such as forming the metal layer through electroplating, thermal spraying, vacuum evaporation, sputtering, or ion plating. Those skilled in the art can choose the appropriate process type based on the specific circumstances.

[0082] Based on the above embodiments, as a preferred embodiment of the temporary grounding plug, such as... Figure 8 As shown, the grounding head 3 has a grounding head stepped hole 33, such as... Figure 9 As shown, the conductor 32 is a stepped columnar structure that is inserted into the stepped hole 33 of the grounding head.

[0083] This embodiment not only provides a preferred structural form for the grounding head 3, but also a preferred structural form for the conductor 2 32, and a preferred assembly structure relationship between the two. The stepped hole 33 of the grounding head can both accommodate the stepped columnar conductor 2 32 and position the stepped columnar conductor 2 32. With the help of the mounting surface of the grounding base 2, the conductor 2 32 can be firmly fixed inside.

[0084] The conductor 32 is connected to the step hole 33 of the grounding head by conductive adhesive, welding, or interference fit. When the conductor 32 is connected to the step hole 33 of the grounding head by conductive adhesive, the conductor 32 can be easily removed from the step hole 33 of the grounding head after the grounding base 2 is removed from the mounting surface. When the conductor 32 is connected to the step hole 33 of the grounding head by welding or interference fit, the reliability of the connection between the two can be further guaranteed.

[0085] Based on the above embodiments, as a preferred embodiment of the temporary grounding plug, the grounding head 3 is connected to a terminal 4, which is used to abut against the conductor 32 and be threaded, welded, or crimped to the grounding head 3.

[0086] This embodiment provides a more preferred assembly relationship between the grounding head 3 and the conductor 32, which is particularly suitable for temporary grounding plugs to be directly grounded through the terminal 4 and the grounding wire 5 connected to the terminal 4, while the temporary grounding socket is used to be directly connected to aircraft such as airplanes. One end of the terminal 4 is used to connect the grounding wire, and the other end is used to connect the grounding head 3. At the same time, the end connected to the grounding head 3 is also used to press and position the conductor 32. If the terminal 4 and the grounding head 3 are threadedly connected, the various components can be easily assembled and disassembled.

[0087] Preferably, when the terminal 4 is threadedly connected to the grounding head 3, one end of the terminal 4 is provided with a terminal connection thread 43, and the other end of the terminal 4 is provided with a terminal wiring hole 41 for crimping the grounding wire 5. The large-diameter section of the inner cavity of the grounding head 3 is provided with a grounding head threaded hole 34 that is adapted to the terminal connection thread 43. After the terminal connection thread 43 and the grounding head threaded hole 34 are assembled, the conductor 2 32 can be firmly pressed into the grounding head stepped hole 33 of the grounding head 3.

[0088] Preferably, such as Figure 3As shown, when the terminal 4 is welded or crimped to the grounding head 3, one end of the grounding head 3 is provided with a grounding head aperture 35, which is the large-diameter section of the grounding head stepped hole 33, and the other end of the grounding head 3 is the small-diameter section of the grounding head stepped hole 33; one end of the terminal 4 is a terminal wiring hole 41, and the other end is a terminal connection part 44. After the terminal connection part 44 is assembled with the grounding head aperture 35, it can be fixed by crimping or welding, so that the conductor 2 32 is firmly pressed into the grounding head stepped hole 33 of the grounding head 3.

[0089] Preferably, the terminal wiring hole 41 is provided with a terminal inspection hole 42 for observing the crimping status of the grounding wire 5.

[0090] Preferably, after the terminal connection thread 43 is assembled with the grounding head threaded hole 34, the conductor 32 is firmly pressed against the grounding head stepped hole 33 of the grounding head 3. Specifically, the small diameter section of the conductor 32 matches the small diameter hole at the outer end of the grounding head stepped hole 33, the large diameter section of the conductor 32 matches the large diameter hole inside the grounding head stepped hole 33, and the outer end face of the conductor 32 is flush with the outer end face of the grounding head 3. When the temporary grounding plug is assembled with the temporary grounding socket, the outer end face of the grounding head 3 and the outer end face of the conductor 32 simultaneously contact the temporary grounding socket.

[0091] Preferably, when the temporary grounding socket is designed to include a grounding base 2, a conductor 21, a positioning hole 22, and a stepped hole 23 for the grounding base, and the temporary grounding plug is designed to include a grounding head 3, a positioning pin 31, a conductor 32, and a stepped hole 33 for the grounding head, when the temporary grounding plug is assembled with the temporary grounding socket, the conductor 21 and the conductor 32 are in close contact with each other and their axial projections overlap each other, the grounding head 3 and the grounding base 2 are in close contact with each other, and the stepped hole 23 for the grounding base and the stepped hole 33 for the grounding head are coaxial.

[0095] Conductor 21 and grounding base 2 are connected together by conductive adhesive, such as Figure 12 As shown, the grounding base 2 is mounted on the fuselage structure of the aircraft 1 using mounting screws 25, and generally does not require disassembly. The contact surfaces of the grounding base 2 and the grounding head are provided with matching positioning holes 22 and positioning pins 31 to prevent movement between them. The conductor 2 32 is connected to the grounding head 3 with conductive adhesive. The grounding head 3 is connected to the terminal 4 via a thread. The terminal tail is crimped or soldered with a grounding wire 5. The terminal 4 has an inspection hole 42 in the middle to check the connection status of the grounding wire 5. In use, simply connect the grounding head 3 to the grounding base.
