Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a power supply track. Background Technology

[0002] Track sockets, as a modular power supply device, have been widely used in recent years due to their flexibility and convenience. As shown in the prior art (CN222029438U), its track base has multiple fixed potential taps arranged along its length, and the socket adapter can be plugged into any of these potential taps to achieve position adjustment. While this solution avoids the traditional sliding track structure, it still has the following safety defects: Insufficient socket protection and sealing: Although the prior art has a safety door assembly above the conductive plug end inside the track base, it only covers the conductive end and does not seal the second plug on the sealing plate (i.e., the sealing plate plug). When the adapter is not plugged in, the sealing plate plug is in a normally open state, allowing liquids or foreign objects to directly enter the track interior through the plug, leading to short circuits or leakage risks. Simultaneously, the sealing plate partially seals the plug gap through protrusions, but the redundant design of the plug gap and socket still results in insufficient sealing, especially in humid or splashing environments where the hazard is significant. These problems indicate that the prior art fails to achieve comprehensive protection for the power supply track sockets, and an improved solution that can both seal the sockets and simplify the structure is urgently needed to improve overall safety and reliability. To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a power supply track that offers advantages such as improved plug protection and sealing, simplified structure, and enhanced safety and reliability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This application provides a power tapping track, the technical solution of which is as follows: A power tapping track includes a track base, a conductive component disposed inside the track base, a support plate, and a sealing plate longitudinally movably disposed between the support plate and the top plate of the track base. The track base has multiple potential taps arranged along its length, and the sealing plate has sealing plate sockets corresponding to the multiple potential taps. The power tapping track also includes a safety door assembly, the safety door assembly including a protective door laterally slidably disposed on the support plate, and the protective door having a sealing plate socket corresponding to each potential tap. Corresponding neutral, live, and ground protrusions; when the socket adapter is not plugged in, the neutral, live, and ground protrusions of the protective door close the sealing plate socket; when the socket adapter is plugged in, its neutral, live, and ground protrusions press down on the corresponding neutral, live, and ground protrusions, driving the protective door to move downward and laterally to avoid the protrusions, thus opening the sealing plate socket; the protective door is elastically connected to the bracket plate or track base by a return spring, for resetting after the socket adapter is removed.

[0006] Furthermore, this application also proposes that a guide rail is provided on the inner side wall of the track base, and sliding columns are provided on both sides of the protective door, with the sliding columns embedded in the guide rail; the path of the guide rail is configured such that when the protective door is pressed down by the insert column, the sliding column slides along the guide rail, guiding the protective door downward and laterally.

[0007] Furthermore, this application also proposes that a cover plate is fixed above the support plate, and the protective door is slidably disposed between the support plate and the cover plate; the cover plate is provided with a top sliding groove hole, and the neutral wire protrusion, live wire protrusion and ground wire protrusion of the protective door are embedded in the top sliding groove hole and can move laterally along it.

[0008] Furthermore, this application also proposes that a side sliding groove is provided between the side walls of the bracket plate and the cover plate, and the sliding column passes through the side sliding groove and extends into the guide rail; the guide rail is provided on both inner side walls of the track base, and the sliding column is provided on both sides of the protective door.

[0009] Furthermore, this application also proposes that the protective door, bracket plate or cover plate is provided with a spring groove, and the reset spring is embedded in the spring groove, with one end supporting the protective door and the other end supporting the bracket plate or cover plate.

[0010] Furthermore, this application also proposes that a groove is provided on the bottom plate inside the track base, and the ground wire contact, live wire contact and neutral wire contact of the conductive component are fixed in the groove; a base is provided above the groove, and the guide slide rail is provided on the side wall of the base; the end corner of the bracket plate is elastically supported on the base by a first spring, and the base and the bracket plate are provided with base sockets corresponding to the sealing plate sockets; the sealing plate is elastically supported on the base by a second spring.

[0011] Furthermore, this application also proposes that the base has arc-shaped pieces at its four corners, each arc-shaped piece forming a spring cavity, and the spring cavity has an opening on one side that extends vertically through it; the support plate has legs at its four corners, each leg being inserted from the top of the spring cavity and supported by a first spring, and the end of each leg being larger than the diameter of the opening.

[0012] Furthermore, this application also proposes that a slot is constructed on the top plate of the track base, a protrusion is provided on the top of the sealing plate, and the sealing plate slot is opened on the protrusion; when the sealing plate is raised to the point where both sides are supported on the lower end face of the top plate, the protrusion is embedded and at least partially closes the slot.

[0013] Furthermore, this application also proposes that elastic arms are symmetrically arranged on both sides of the bottom center of the protective door, and the elastic arms elastically support the protective door on the bottom surface of the support plate, so that a lateral sliding gap is formed between the support plate and the protective door and the protective door is kept in a horizontal position.

[0014] Furthermore, this application also proposes that the ground wire protrusion is located in the middle of the protective door, and the neutral wire protrusion and the live wire protrusion are arranged on both sides; the lower ends of the neutral wire protrusion and the live wire protrusion are provided with hooks, and when one side of the protrusion is pressed down, the hooks are engaged in the base socket of the bracket plate to restrict the lateral movement of the protective door; when both sides of the protrusion are pressed down at the same time, the protective door and the bracket plate move down synchronously and are guided to move laterally by the guide rail.

[0015] As can be seen from the above, the power supply track and its safety door assembly provided in this application solve the problem of insufficient protection and sealing of the socket in the prior art by setting the safety door assembly and the closed structure of the sealing plate socket. It has the advantages of improving the protection and sealing of the socket, simplifying the structure, and improving safety and reliability. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0031] like Figure 1-10 As shown, this embodiment relates to a power supply track, including a track base 1, a conductive component disposed inside the track base 1, a support plate 12, and a sealing plate 4 longitudinally movably disposed between the support plate 12 and the top plate of the track base 1. Multiple potential taps 10 are arranged along the length of the track base 1, and the sealing plate 4 is provided with sealing plate sockets 43 corresponding to the multiple potential taps 10. The power supply track also includes a safety door assembly, which includes a protective door 6 laterally slidably disposed on the support plate 12. The protective door 6 is provided with a neutral wire protrusion 61, a live wire protrusion 62, and a ground wire protrusion 63 corresponding to the sealing plate socket 43 of each potential tap 10. When the potential tap 10 is not plugged into a socket adapter 2, the neutral wire protrusion 61, the live wire protrusion 62, and the ground wire protrusion 63 of the protective door 6 close the sealing plate socket 43. When the socket adapter 2 is inserted into the power tap 10, its neutral wire terminal 221, live wire terminal 222, and ground wire terminal 223 press down on the corresponding neutral wire protrusion 61, live wire protrusion 62, and ground wire protrusion 63, driving the protection door 6 to move downward and laterally to avoid the terminals, thus opening the sealing plate socket 43. The protection door 6 is elastically connected to the bracket plate 12 or the track base 1 by a return spring 64, which is used to reset after the socket adapter 2 is removed.

[0032] The neutral wire protrusion 61, live wire protrusion 62, and ground wire protrusion 63 of the protective door 6 can be cylindrical, square, or other geometric shapes. Their size and shape can be adjusted according to the specific design of the sealing plate socket 43 to ensure complete closure of the socket. The lateral sliding of the protective door 6 can be achieved through guide rails, tracks, or other guiding structures. Furthermore, the sliding path of the protective door 6 can be precisely controlled by the guide rail 71 to ensure that it can move smoothly and open the socket when the socket adapter 2 is inserted. The return spring 64 can be a coil spring, leaf spring, or other elastic element, and its installation position and connection method can be adjusted according to specific design requirements.

[0033] This technical solution addresses the issue of the power rail socket not being fully closed when the socket adapter 2 is not plugged in by introducing a safety door assembly. Specifically, the correspondence between the neutral wire protrusion 61, live wire protrusion 62, and ground wire protrusion 63 of the protective door 6 and the sealing plate socket 43 ensures that the socket is closed when not in use, preventing liquids or foreign objects from entering the rail. When the socket adapter 2 is inserted, its protrusions press down on the protrusions of the protective door 6, driving the protective door 6 to move and open the socket, ensuring smooth insertion. The reset spring 64 allows the protective door 6 to automatically reset and re-close the socket after the socket adapter 2 is removed. Compared with existing technologies, this solution effectively improves the safety and reliability of the power rail through the dynamic closing mechanism of the protective door 6, and also makes the overall appearance of the product more aesthetically pleasing.

[0034] exist Figure 5-7 In the specific implementation shown, a guide rail 71 is provided on the inner side wall of the track base 1, and sliding posts 65 are provided on both sides of the protective door 6. The sliding posts 65 are embedded in the guide rail 71. The path of the guide rail 71 is configured such that when the protective door 6 is pressed down by the posts, the sliding posts 65 slide along the guide rail 71, guiding the protective door 6 to move downward and laterally.

[0035] Specifically, the path design of the guide rail 71 can include a combination of straight segments and curved / sloping segments, where the straight segments guide the protective door 6 to move downwards, and the curved / sloping segments guide the protective door 6 to move laterally. As a preferred embodiment, the curved segments of the guide rail 71 can be designed as arcs to reduce the frictional resistance of the sliding column 65 during movement, ensuring smooth movement of the protective door 6. Furthermore, the guide rail 71 can be made of a metal or composite material with high wear resistance to extend its service life. For this purpose, the sliding column 65 of the protective door 6 can be cylindrical or spherical. A cylindrical sliding column 65 offers higher sliding stability within the guide rail 71, while a spherical sliding column 65 provides greater flexibility during multi-directional movement. Further, the surface of the sliding column 65 can be coated with a lubricating coating to reduce friction with the guide rail 71, improving the accuracy and stability of the protective door 6's movement. Thus, this technical solution, through the cooperation of the guide rail 71 and the sliding column 65, achieves accurate and stable movement of the protective door 6 when pressed down by the insertion column. Compared with existing technologies, this solution avoids the problem of the protective door 6 shifting or jamming during movement, thus improving the reliability and safety of the protective door 6. Specifically, the path configuration of the guide rail 71 ensures that the trajectory of the protective door 6 is controllable during movement, while the tight cooperation between the sliding column 65 and the guide rail 71 further enhances the stability of the protective door 6's movement. Therefore, this technical solution effectively solves the technical problem of ensuring that the protective door 6 can move accurately and stably downward and laterally when pressed down by the insertion column.

[0036] Furthermore, a cover plate 72 is fixed above the support plate 12, and the protective door 6 is slidably disposed between the support plate 12 and the cover plate 72. The cover plate 72 is provided with a top sliding groove hole 721, into which the neutral wire protrusion 61, live wire protrusion 62, and ground wire protrusion 63 of the protective door 6 are embedded and can move laterally. The design of the top sliding groove hole 721 allows the protrusions of the protective door 6 to move freely within the groove hole of the cover plate 72, thereby solving the problem of lateral movement of the protrusions when the protective door 6 slides. As a preferred embodiment, the top sliding groove hole 721 can be designed as a long strip, with its length direction consistent with the sliding direction of the protective door 6, to ensure smooth movement of the protrusions within the groove hole. In addition, the width of the groove hole can be slightly larger than the diameter of the protrusions to reduce friction and improve sliding efficiency. Furthermore, limiting structures can be provided at both ends of the groove hole to prevent the protrusions from sliding out of the groove hole. Therefore, this technical solution ensures that the protective door 6 remains stable during sliding, while effectively controlling the lateral movement of the protruding column. Compared with existing technologies, this solution not only simplifies the structure but also improves the safety and reliability of the power supply track. Specifically, the protective door 6 and the support plate 12 always cooperate and will not disengage, ensuring stability during sliding. At the same time, the free movement of the protruding column within the sliding groove avoids jamming or damage caused by lateral movement, further improving the service life and safety of the device.

[0037] Furthermore, a side sliding groove 731 is provided between the side walls of the support plate 12 and the cover plate 72, and the sliding column 65 passes through the side sliding groove 731 and extends into the guide rail 71. Guide rails 71 are provided on both inner side walls of the track base 1, and sliding columns 65 are provided on both sides of the protective door 6. The side sliding groove 731 allows the sliding column 65 to slide between the support plate 12 and the cover plate 72, while the guide rails 71 further define the sliding path of the sliding column 65, ensuring the stability and accuracy of the protective door 6 during sliding. Through the cooperation of the side sliding groove 731 and the guide rails 71, the protective door 6 can slide smoothly between the support plate 12 and the cover plate 72 without shifting or jamming during sliding, thereby improving the usability and safety of the protective door 6. Specifically, the design of the side sliding groove 731 can include various implementation methods. For example, the side sliding groove 731 can be straight, curved, or a combination of these to adapt to different sliding path requirements. Furthermore, the width and depth of the side sliding groove 731 can be adjusted according to the dimensions of the sliding column 65 to ensure that the sliding column 65 does not wobble or detach during sliding. The design of the guide rail 71 can also have various variations; for example, the guide rail 71 can be set on one or both sides to further increase the stability of the sliding column 65. The guide rail 71 can be made of wear-resistant and corrosion-resistant materials to extend its service life. Thus, this technical solution, through the cooperation of the side sliding groove 731 and the guide rail 71, effectively solves the problem of guiding and limiting the sliding column 65 when the protective door 6 slides between the bracket plate 12 and the cover plate 72. Compared with existing technologies, this solution not only improves the stability and accuracy of the sliding of the protective door 6, but also simplifies the structural design, reduces friction and wear during sliding, thereby improving the overall usability and safety.

[0038] like Figure 6As shown, a spring groove 66 is provided on the protective door 6, the support plate 12, or the cover plate 72. A return spring 64 is embedded in the spring groove 66, with one end supporting the protective door 6 and the other end supporting the support plate 12 or the cover plate 72. The specific design of the spring groove 66 can include various forms. For example, the spring groove 66 can be designed as a U-shaped groove or a rectangular groove, with its depth and width adapted to the dimensions of the return spring 64 to ensure that the return spring 64 can be securely embedded within it. The inner wall of the spring groove 66 can be provided with anti-slip textures or protrusions to increase the friction between the return spring 64 and the groove wall, preventing the spring from sliding or shifting during movement. Furthermore, the position of the spring groove 66 can be optimized according to the movement trajectory of the protective door 6, for example, by being located at the bottom or side of the protective door 6, to ensure that the return spring 64 can effectively apply elastic force when the protective door 6 moves. Specifically, one end of the return spring 64 is supported by the protective door 6, and the other end is supported by the bracket plate 12 or the cover plate 72. This design ensures that the return spring 64 maintains a stable support relationship during the movement of the protective door 6. When the socket adapter 2 is inserted, the protective door 6 is subjected to downward pressure and moves, compressing the return spring 64. When the socket adapter 2 is removed, the return spring 64 pushes the protective door 6 back to its original position through elastic force, thereby realizing the automatic reset function of the protective door 6. The spring groove 66 not only simplifies the installation structure of the return spring 64 but also improves the fixing effect of the return spring 64, avoiding the problem of the spring falling off or shifting during movement. Compared with the prior art, the technical solution of this application significantly improves the installation stability of the return spring 64 and the reset reliability of the protective door 6 through the design of the spring groove 66. The spring groove 66 provides a precise installation position for the return spring 64, ensuring that it is always in the correct working state during the movement of the protective door 6. In addition, the spring groove 66 has a simple structure, is easy to process and assemble, and reduces production costs and process complexity. This design not only solves the problem of installing and fixing the reset spring 64 on the protective door 6, bracket plate 12 or cover plate 72, but also further improves the safety and reliability of the power supply track during use.

[0039] like Figure 5As shown, a groove 81 is provided on the bottom plate inside the track base 1. The ground contact 82, live contact 83, and neutral contact 84 of the conductive components are fixed in the groove 81. A base 86 is provided above the groove 81, and a guide rail 71 is provided on the side wall of the base 86. The end corner of the bracket plate 12 is elastically supported on the base 86 by a first spring 85. The base 86 and the bracket plate 12 are provided with base sockets 42 corresponding to the sealing plate socket 43. The sealing plate 4 is elastically supported on the base 86 by a second spring 41. The design of the groove 81 allows the ground contact 82, live contact 83, and neutral contact 84 of the conductive components to be firmly fixed inside the track base 1, avoiding poor contact or damage caused by vibration or external force. The base 86 not only provides support for the bracket plate 12, but also ensures the stability of the protective door 6 during movement through the guide rail 71 on its side wall, preventing displacement or jamming. The corners of the bracket plate 12 are elastically supported on the base 86 by the first spring 85, ensuring that the bracket plate 12 maintains elastic support under the action of the spring and ensuring accurate alignment of the sealing plate socket 43. The sealing plate 4 is elastically supported on the base 86 by the second spring 41, further ensuring accurate alignment and sealing of the sealing plate socket 43. Specifically, the shape and size of the groove 81 can be adjusted according to the specific needs of the conductive components to achieve the best fixing effect. The base 86 can be made of high-strength, wear-resistant material to enhance its service life and stability. The elastic coefficients of the first spring 85 and the second spring 41 can be adjusted according to the actual application scenario to ensure that the bracket plate 12 and the sealing plate 4 maintain good elastic support under different working conditions. The path of the guide rail 71 can be further optimized to guide the protective door 6 to move more smoothly and reduce friction and resistance. Thus, this technical solution effectively solves the technical problems of fixing the conductive components inside the track base 1 and setting the guide rail 71 through the synergistic effect of the groove 81, the base 86, the guide rail 71, the first spring 85 and the second spring 41. Compared with existing technologies, this solution not only improves the stability of the conductive components, but also ensures the smooth movement of the protective door 6 through the design of the guide rail 71, while ensuring the accurate alignment and sealing of the sealing plate socket 43 through the elastic support of the spring, thereby improving the safety and reliability of the overall equipment.

[0040] Furthermore, arc-shaped pieces 87 are provided at the four corners of the base 86, and spring cavities 88 are formed within the arc-shaped pieces 87. Each spring cavity 88 has an opening 89 extending vertically through one side. Support legs 90 are provided at the four corners of the support plate 12. The support legs 90 are inserted into the top of the spring cavity 88 and supported by the first spring 85. The end of the support leg 90 is larger than the diameter of the opening 89. Specifically, the shape of the arc-shaped pieces 87 can be adjusted according to actual needs, such as using a semi-circular, elliptical, or other arc-shaped structure to ensure the stability and elastic support effect of the spring cavity 88. The opening 89 of the spring cavity 88 can be designed as circular, square, or other shapes to accommodate the insertion and limiting requirements of the support legs 90. The end of the support leg 90 can be designed as spherical, conical, or other shapes to ensure that it is larger than the diameter of the opening 89, thereby achieving an effective limiting function. The material and elastic coefficient of the first spring 85 can be selected according to actual needs to ensure the elastic support effect of the support plate 12 on the base 86. To address this, the proposed technical solution utilizes the design of the arc-shaped plate 87 and the spring cavity 88 to achieve elastic support for the support plate 12 on the base 86. Simultaneously, the design of the end of the support leg 90 being larger than the diameter of the opening 89 restricts the range of movement of the support plate 12, ensuring the stability and limiting effect of the support plate 12 on the base 86. Compared with existing technologies, this solution not only simplifies the structure but also improves the stability and safety of the support plate 12, effectively solving the problems of elastic support and limiting between the base 86 and the support plate 12.

[0041] Furthermore, a slot 111 is constructed on the top plate of the track base 1, and a protrusion 44 is provided on the top of the sealing plate 4. A sealing plate socket 43 is opened on the protrusion 44. When the sealing plate 4 is raised to the point where its two sides are supported on the lower end face of the top plate, the protrusion 44 is inserted into and at least partially closes the slot 111. The slot 111 can be constructed by opening a narrow opening on the top plate of the track base 1. The width and length of the opening can be adjusted according to actual needs to ensure that the protrusion 44 of the sealing plate 4 can be inserted smoothly. The protrusion 44 of the sealing plate 4 can be achieved by providing a raised structure on the top of the sealing plate 4. The shape and size of the raised structure should match the slot 111 to ensure a tight fit when inserted. The sealing plate socket 43 can be opened at the center of the protrusion 44, and its shape and size should correspond to the tapping potential 10 so that the socket adapter 2 can be inserted smoothly. When the sealing plate 4 is raised, its two sides support the lower end face of the top plate, allowing the protrusion 44 to be embedded in the slot 111, thus partially sealing the slot 111. Therefore, this technical solution achieves partial sealing of the slot 111 through the design of the protrusion 44 of the sealing plate 4 embedding into the slot 111. This structure serves both an aesthetic purpose and a dustproof function. Combined with the sealing scheme of the sealing plate slot 43, it prevents liquids or foreign objects from entering the track through the slot, reducing the risk of short circuits or leakage. Compared with existing technologies, this solution not only simplifies the structure but also improves sealing and safety, especially in humid or splashing environments.

[0042] like Figure 3As shown in Figure 5-7, elastic arms 67 are symmetrically arranged on both sides of the center of the bottom surface of the protective door 6. The elastic arms 67 elastically support the protective door 6 against the bottom surface of the support plate 12, creating a lateral sliding gap between the support plate 12 and the protective door 6 and keeping the protective door in a horizontal position. Specifically, the design of the elastic arms 67 allows the protective door 6 to slide flexibly laterally when subjected to downward pressure, while maintaining an elastic connection with the support plate 12. In a preferred embodiment, the elastic arms 67 can be made of elastic metal or plastic materials, and their shape can be a curved sheet structure or a spring structure. One end of the elastic arm 67 is fixed to the bottom surface of the protective door 6, while the other end contacts the bottom surface of the support plate 12, achieving lateral sliding of the protective door 6 through elastic deformation. Furthermore, the symmetrical arrangement of the elastic arms 67 ensures that the protective door 6 experiences uniform force on both sides when subjected to downward pressure, avoiding tilting or jamming problems caused by uneven force distribution. To address this issue, the technical solution of this application maintains a stable gap between the protective door 6 and the support plate 12 through the supporting action of the elastic arm 67, thereby solving the technical problem of lateral sliding gap between the protective door and the support plate. Compared with the prior art, this application not only ensures the flexible movement of the protective door, but also, through the symmetrical arrangement of the elastic arms, ensures that the protective door is balanced on both sides when the socket adapter is removed, thus avoiding the problem of inconsistent heights of the neutral wire protrusion, live wire protrusion, and ground wire protrusion. Therefore, the technical solution of this application improves the flexibility of the protective door's movement while further enhancing its stability and reliability.

[0043] Furthermore, the ground wire protrusion 63 is located in the middle of the protective door 6, with the neutral wire protrusion 61 and the live wire protrusion 62 positioned on either side. The lower ends of the neutral wire protrusion 61 and the live wire protrusion 62 are equipped with hooks 68. When one side of the protrusion is pressed down, the hooks 68 engage with the base socket 42 of the support plate 12 to restrict the lateral movement of the protective door 6. When both sides of the protrusion are pressed down simultaneously, the protective door 6 moves downward synchronously with the support plate 12 and is guided laterally by the guide rail 71. Specifically, the design of the hooks 68 restricts the lateral movement of the protective door 6 when one side of the protrusion is pressed down, thus ensuring the functionality of the protective door 6. The shape and size of the hooks 68 can be adjusted according to actual needs to ensure they can effectively engage with the base socket 42. In addition, the path of the guide rail 71 is configured to guide the protective door 6 to move downward synchronously and laterally when both sides of the protrusion are pressed down, thereby achieving flexible movement and accurate positioning of the protective door 6. The materials and structure of the guide rail 71 can also be optimized according to the actual application scenario to improve its durability and guiding accuracy.

[0044] Therefore, this application solves the problem of limited lateral movement of the protection door 6 when one side of the protrusion is pressed down by placing the ground wire protrusion 63 in the middle of the protection door 6, with the neutral wire protrusion 61 and the live wire protrusion 62 on both sides, and setting hooks 68 at the lower ends of the neutral wire protrusion 61 and the live wire protrusion 62. When one side of the protrusion is pressed down, the hooks 68 engage with the base socket 42 of the bracket plate 12, restricting the lateral movement of the protection door 6 and ensuring the functionality of the protection door 6. Only when both sides of the protrusion are pressed down simultaneously, the protection door 6 moves downward synchronously with the bracket plate 12, and is guided to move laterally by the guide rail 71, realizing flexible movement and accurate positioning of the protection door 6. This technical solution, through the cooperation of the hooks 68 and the guide rail 71, effectively solves the problem of movement of the protection door 6 when one or both sides of the protrusion are pressed down, improving the safety and reliability of the power supply track.
