Description

Technical Field

[0001] This application relates to the field of socket technology, and more particularly to a power rail and a rail socket. Background Technology

[0002] As a new type of socket product, track sockets mainly consist of a power rail (also known as an electrical track) and adapters. Generally, the number of adapters can be increased or decreased arbitrarily within the power rail, and the position of the adapters can also be adjusted arbitrarily on the power rail. Furthermore, the power rail can be installed on a wall or embedded in a desktop, making track sockets not only flexible in configuration but also more convenient to use.

[0003] In related technologies, the housing of the power rail has a slot that provides a plug-in / plug-out channel for the adapter. However, external impurities can easily enter the housing through this slot, potentially damaging the components inside and affecting the safety of the power rail. Summary of the Invention

[0004] In view of this, embodiments of this application provide a power rail and rail socket, which can improve the safety of the power rail.

[0005] On the one hand, embodiments of this application provide a power rail, which includes a housing and a protective door;

[0006] The housing has a receiving cavity and an adapter socket communicating with the receiving cavity;

[0007] The protective door includes a displacement member and a rotating member. The displacement member is located in the receiving cavity and can be displaced relative to the housing. The rotating member is rotatably connected to the displacement member.

[0008] When the rotating member is in its initial state, it closes the adapter socket. When the rotating member is pressed, it can rotate into the receiving cavity and the displacement member can move to avoid the insertion path from the adapter socket into the receiving cavity.

[0009] Optionally, when the rotating member is subjected to an external force, the rotating member first rotates into the receiving cavity, and then the displacement member moves.

[0010] Optionally, the rotating component includes a closing component and a connecting component;

[0011] The connecting member is fixedly connected to the closing member and rotatably connected to the displacement member;

[0012] The closing member has an abutting surface, wherein when the rotating member rotates into the receiving cavity to a predetermined angle, the abutting surface abuts against the displacement member to restrict the rotating member from continuing to rotate into the receiving cavity.

[0013] Optionally, the displacement member has a recessed portion that is recessed in a direction away from the adapter socket;

[0014] The connecting member has a first protrusion on the side opposite to the closing member, and the first protrusion protrudes in a direction away from the closing member;

[0015] When the rotating member is in the initial state, the first protrusion abuts against the recess to restrict the rotating member from rotating away from the receiving cavity.

[0016] Optionally, the displacement element has a pivot and a torsion spring;

[0017] The connecting member is rotatably connected to the rotating shaft, the core of the torsion spring is sleeved on the rotating shaft, the first arm of the torsion spring abuts against the displacement member, and the second arm of the torsion spring abuts against the closing member, forcing the rotating member to tend towards the initial state.

[0018] Optionally, the displacement member has a first protrusion and a second protrusion on the side near the rotating member, a first notch is formed between the first protrusion and the second protrusion facing the rotating member, the rotating shaft passes through the first notch from the first protrusion to the second protrusion, and the recess is located on the side of the first notch away from the rotating member.

[0019] Optionally, the closing member includes a second protrusion, wherein when the rotating member is in the initial state, the second protrusion engages with the adapter socket.

[0020] Optionally, the sealing member further includes a first low-profile portion and a second low-profile portion, the first low-profile portion and the second low-profile portion being located on both sides of the second protrusion, and when the second protrusion is inserted into the adapter socket, the first low-profile portion and the second low-profile portion are both opposite to the inner wall of the receiving cavity on the side where the adapter socket is located.

[0021] Optionally, when the rotating member is in its initial state, the surface of the rotating member facing away from the receiving cavity is further away from the receiving cavity relative to the inner edge of the adapter socket.

[0022] Optionally, when the rotating member is in its initial state, the surface of the rotating member facing away from the receiving cavity is flush with the outer edge of the adapter socket.

[0023] Optionally, the protective door further includes a base and an elastic telescopic member;

[0024] The seat is fixed inside the cavity. The seat and the rotating member are located on opposite sides of the displacement member. The two ends of the elastic telescopic member abut against the seat and the displacement member, respectively. The displacement member can move along the telescopic direction of the elastic telescopic member.

[0025] Optionally, either the base member or the displacement member is provided with at least one slide rail, and the other is provided with at least one slide groove. The slide rail and the corresponding slide groove are slidably engaged to allow the displacement member to move relative to the base member.

[0026] Optionally, when the external force is removed, the displacement member first moves toward the direction closer to the insertion path, and then the rotating member rotates away from the receiving cavity.

[0027] On the other hand, this application embodiment also provides a track socket, the track socket including at least one adapter and the power track described in any of the above claims, wherein the power supply part of the adapter can be inserted into the housing through the adapter socket.

[0028] The power rail provided in this embodiment includes a housing and a protective door. The housing has a receiving cavity and an adapter socket communicating with the receiving cavity. The protective door includes a displacement member and a rotating member. The displacement member is located in the receiving cavity, and the rotating member is rotatably connected to the displacement member. When the adapter is inserted into the receiving cavity from the adapter socket, the rotating member, under the pressure of the adapter, can rotate into the receiving cavity, and the displacement member can move to avoid the insertion path from the adapter socket into the receiving cavity, thus allowing the adapter to be smoothly inserted into the receiving cavity to draw power. When no adapter is inserted into the power rail, the rotating member in its initial state closes the adapter socket. As can be seen from the above, by setting a protective door that can both rotate and translate inside the housing of the power rail, the adapter socket can be closed in the initial state, and the insertion path can be better avoided when the power-drawing part of the adapter is inserted into the receiving cavity to draw power. This setting can promptly prevent external impurities from entering the housing from the adapter socket, thereby protecting the components inside the housing and improving the safety of the power rail.

[0045] On the one hand, combined with Figure 1 As shown, this application embodiment provides a power rail, which includes a housing 100 and a protective door 200. The housing 100 has a receiving cavity 110 and an adapter socket 120 communicating with the receiving cavity 110. It should be noted that, as Figure 3 As shown, the receiving cavity 110 can generally house multiple conductive plates 300, such as L-polar conductive plates, N-polar conductive plates, and / or E-polar conductive plates (not shown in the figure), where the E-polar conductive plate is also called a grounding conductive plate. An insulating strip 400 for engaging the corresponding conductive plates 300 can also be installed within the receiving cavity 110. It should be understood that other related components for achieving conductivity can also be installed within the receiving cavity 110. The power-taking part of the adapter, which mates with the power rail, can be inserted into the receiving cavity 110 through the adapter socket 120 and contact the conductive plates 300, thereby enabling current conduction to achieve power taking.

[0046] Combination Figure 2 , Figure 3 and Figure 4 As shown, the protective door 200 includes a displacement member 210 and a rotating member 220. The displacement member 210 is located in the receiving cavity 110 and can be displaced relative to the housing 100. The rotating member 220 is rotatably connected to the displacement member 210. It should be noted that... Figure 2 , Figures 3 to 4 The position change state of the protection door 200 as the power take-off part of the adapter is gradually inserted into the receiving cavity from the adapter socket 120. Figure 2 To protect the initial position of door 200, Figure 4To protect the door 200 at the endpoint corresponding to the power take-off section of the adapter being fully inserted into the receiving cavity, Figure 3 The protective door 200 in the middle is between Figure 2 and Figure 4 The positions between.

[0047] Among them, such as Figure 2 As shown, when the rotating part 220 is in its initial state, the rotating part 220 closes the adapter socket 120. Combined with... Figure 3 and Figure 4 As shown, when the adapter begins to be inserted into the receiving cavity 110 from the adapter socket 120, the power-taking part of the adapter contacts the rotating member 220 and applies pressure to the rotating member 220 towards the receiving cavity 110. After being pressed, the rotating member 220 can rotate into the receiving cavity 110, and the displacement member 210 can move to avoid the insertion path from the adapter socket 120 into the receiving cavity 110. It should be noted that after the rotating member 220 begins to rotate, it gradually tilts. The tilted rotating member 220 provides guidance for the adapter, allowing it to smoothly and steadily insert into the receiving cavity 110 along the insertion path. In this application, the insertion path generally refers to the path taken by the power-taking part of the adapter when it enters the receiving cavity 110 to take power, which is generally vertically downward from the adapter socket. At this time, the movement direction of the displacement member 210 driven by the rotating member 220 is not entirely vertically downward, but at least part of it is used to avoid the insertion path or to offset the direction of the adapter socket.

[0048] Using the power rail provided in this embodiment, when the adapter is inserted into the receiving cavity 110 through the adapter socket 120, the rotating member 220, under the pressure of the adapter, can rotate into the receiving cavity 110, and the displacement member 210 can move to avoid the insertion path from the adapter socket 120 into the receiving cavity 110, thus allowing the adapter to be smoothly inserted into the receiving cavity 110 to draw power. When no adapter is inserted into the power rail, the rotating member 220, in its initial state, closes the adapter socket 120. As can be seen from the above, by providing a protective door 200 that can both rotate and translate within the housing 100 of the power rail, the adapter socket 120 can be closed in the initial state, and the insertion path can be better avoided when the power-drawing part of the adapter is inserted into the receiving cavity to draw power. This design can promptly prevent external impurities from entering the housing through the adapter socket 120, thereby protecting the components inside the housing 100 and improving the safety of the power rail.

[0049] The following is in conjunction with the appendix Figures 1 to 7 The details and functions of the power rails provided in the embodiments of this application will be described in more specific and detailed manner.

[0050] Combination Figures 2 to 4As shown, in some embodiments, when the rotating member 220 is subjected to an external force, the rotating member 220 first rotates into the receiving cavity 110, and then the displacement member 210 moves. It should be noted that after the rotating member 220 has rotated to its position, the rotating member 220 pushes the displacement member 210 to move. This ensures that the rotating member 220 is completely separated from the adapter socket 120, ensuring that the rotating member 220 does not interfere with the adapter socket 120 when it moves under the influence of the displacement member 210. It can be understood that the external force acting on the rotating member 220 refers to the pressure exerted on the rotating member 220 by the power-taking part of the adapter when the adapter is inserted into the adapter socket 120.

[0051] Combination Figures 2 to 4 As shown, in some embodiments, when the external force is removed, the displacement member 210 first moves towards the insertion path, and then the rotating member 220 rotates away from the receiving cavity 110. It should be noted that when the external force is removed, the displacement member 210, which moves first, can push the rotating member 220 to a position opposite to the adapter socket 120, and then the rotating member 220 rotates, thus ensuring that the rotating member 220 seals the adapter socket. It can be understood that the removal of the external force means that the power-taking part of the adapter is pulled out of the adapter socket 120.

[0052] like Figure 5 As shown, in some embodiments, the rotating member 220 includes a closing member 221 and a connecting member 222. The connecting member 222 is fixedly connected to the closing member 221 and rotatably connected to the displacement member 210. Thus, when the connecting member 222 rotates relative to the displacement member 210, it can drive the closing member 221 to rotate synchronously. The closing member 221 has an abutting surface 2211, wherein when the rotating member 220 rotates into the receiving cavity 110 to a predetermined angle, the abutting surface 2211 abuts against the displacement member 210 to limit the rotating member 220 from continuing to rotate into the receiving cavity 110. It can be understood that through the cooperation of the abutting surface 2211 and the displacement member 210, the rotation angle of the rotating member 220 when rotating into the receiving cavity 110 can be limited, causing the rotating member 220 to stop rotating when it reaches the predetermined angle, thereby preventing the rotating member 220 from failing or being damaged due to excessive rotation.

[0053] like Figure 5As shown, in some embodiments, the contact surface 2211 includes a contact ridge 2216, which extends away from the plane containing the adapter socket 120 and along the extending direction of the adapter socket 120. When the rotating member 220 rotates into the receiving cavity 110 to a predetermined angle, at least a portion of the contact ridge 2216 abuts against the end face of the displacement member 210 facing the rotating member 220. It should be understood that the contact ridge 2216 can limit the rotation angle of the rotating member 220 when it rotates into the receiving cavity 110, to prevent the rotating member 220 from failing or being damaged due to excessive rotation.

[0054] like Figure 5 As shown, in some embodiments, the abutment 2216 has a chamfer. Therefore, when the abutment 2216 abuts against the end face of the rotating member 220, the abutment 2216 is less likely to damage the rotating member 220, thus extending the service life of the protective door 200.

[0055] like Figure 5 As shown, in some embodiments, the displacement member 210 has a recess 211 that is recessed in a direction away from the adapter socket 120. A first protrusion 2221 is provided on the side of the connecting member 222 opposite to the closing member 221, and the first protrusion 2221 protrudes in a direction away from the closing member 221. When the rotating member 220 is in its initial state, the first protrusion 2221 abuts against the recess 211 to restrict the rotation of the rotating member 220 in a direction away from the receiving cavity 110. Understandably, when the adapter is pulled out of the housing 100, the rotating member 220 will gradually rotate from the receiving cavity 110 toward the adapter socket 120. By utilizing the cooperation between the recessed part 211 and the first protruding part 2221, the rotation angle of the rotating member 220 can be limited, preventing the rotating member 220 from failing or being damaged due to excessive rotation. It can also prevent the rotating member 220 from pushing up the housing 100 due to excessive rotation and causing damage to the housing 100, thereby improving the service life of the protective door 200 and the housing 100, which in turn improves the service life of the power rail.

[0056] Combination Figure 5 and Figure 7As shown, in some embodiments, the recess 211 includes a first abutting surface 2111 facing the plane where the adapter socket 120 is located, and the first abutting surface 2111 is parallel to the plane where the adapter socket 120 is located. The first protrusion 2221 has a second abutting surface 2222 facing the first abutting surface 2111. When the rotating member 220 is in its initial state, at least a portion of the second abutting surface 2222 is parallel to and abuts against the first abutting surface 2111. It is understood that when the adapter is pulled out of the housing 100, the cooperation between the second abutting surface 2222 and the first abutting surface 2111 ensures that the rotating member 220 is entirely parallel to the plane where the adapter socket 120 is located, thereby preventing the rotating member 220 from tilting up, and preventing the rotating member 220 from excessively rotating and lifting the surface of the housing 100 where the adapter socket 120 is located.

[0057] like Figure 5 As shown, in some embodiments, the displacement member 210 has a rotating shaft 212 and a torsion spring 213. The connecting member 222 is rotatably connected to the rotating shaft 212. The core 2131 of the torsion spring 213 is sleeved on the rotating shaft 212. The first arm 2132 of the torsion spring 213 abuts against the displacement member 210, and the second arm 2133 of the torsion spring 213 abuts against the closing member 221, forcing the rotating member 220 to tend towards the initial state. It can be understood that the core 2131 of the torsion spring 213 is helical. When the adapter is pulled out from the housing 100, under the action of the torsion spring 213, the connecting member 222 can rotate about the rotating shaft 212 as the center of rotation. In this way, the connecting member 222 can drive the closing member 221 to rotate synchronously, so that the rotating member 220 can achieve automatic reset. In addition, when the power take-off part of the adapter is inserted into the receiving cavity 110, the sealing member 221 will rotate into the receiving cavity 110 under the pressure applied by the adapter. The second arm 2133 of the torsion spring 213 will apply a pushing force to the sealing member 221 toward the insertion path, so that the sealing member 221 and the power take-off part of the adapter are kept in a state of resistance. As a result, the adapter can be smoothly inserted into the receiving cavity 110 along the insertion path, avoiding the adapter from shifting.

[0058] like Figure 5 As shown, in some embodiments, the displacement member 210 includes a first slot 218 with an opening opposite to the plane of the adapter socket 120, and the first arm 2132 of the torsion spring 213 is located within the first slot 218. The closing member 221 includes a second slot 2217 with an opening opposite to the plane of the adapter socket 120, and the second arm 2133 of the torsion spring 213 is located within the second slot 2217. It is understood that the first slot 218 and the second slot 2217 can limit the torsion spring 213 to prevent the torsion spring 213 from disengaging from the rotating member 220 or the displacement member 210 during rotation.

[0059] like Figure 5 As shown, in some embodiments, the displacement member 210 has a first protrusion 214 and a second protrusion 215 on the side near the rotating member 220. A first notch 217 is formed between the first protrusion 214 and the second protrusion 215 facing the rotating member 220. The rotating shaft 212 passes through the first notch 217 from the first protrusion 214 to the second protrusion 215. The recess 211 is located on the side of the first notch 217 away from the rotating member 220. It can be understood that the first protrusion 214 and the second protrusion 215 can position the rotating shaft 212 to prevent the rotating shaft 212 from shifting. In some embodiments, when the rotating member 220 is in the initial state, there is a gap 2174 between the side of the connecting member 222 away from the closing member 221 and the end face of the first notch 217 facing the rotating member 220. It should be noted that the gap 2174 can provide rotation space for the connecting member 222 to rotate, preventing interference between the connecting member 222 and the displacement member 210, that is, ensuring that the rotating member 220 can rotate flexibly.

[0060] like Figure 5 As shown, in some embodiments, the sealing member 221 includes a second protrusion 2212, wherein when the rotating member 220 is in the initial state, the second protrusion 2212 is engaged in the adapter socket 120. It should be noted that the adapter socket 120 is generally located on the top plate of the housing 100. Due to the thickness of its material, the top plate of the housing 100 may have a height difference between its outer and inner walls; or, at the adapter socket of the housing 100, the top plate of the housing 100 may form the shape of the adapter socket, with a height difference between the two ends furthest apart in the same direction. By engaging the second protrusion 2212 within the space formed by the aforementioned height difference, a better sealing effect can be achieved on the adapter socket 120, preventing external impurities from entering the housing 100 through the circumferential wall of the adapter socket 120. This improves the safety of the power rail. Furthermore, since the second protrusion 2212 is sufficient to close the adapter socket 120, a single row of protective doors 200 is sufficient to close the adapter socket 120 within the power rail, eliminating the need for double rows of protective doors 200. This significantly reduces the space occupied by the protective doors 200 within the power rail. Consequently, not only is the number of components within the power rail reduced, improving assembly efficiency and lowering the cost of the power rail, but more space is also provided for arranging other components within the housing 100, facilitating the assembly of multiple components within the housing 100.

[0061] Combination Figure 3 and Figure 5As shown, in some embodiments, the closing member 221 further includes a first low-profile portion 2214 and a second low-profile portion 2215. The first low-profile portion 2214 and the second low-profile portion 2215 are respectively located on both sides of the second protrusion 2212. When the second protrusion 2212 is inserted into the adapter socket 120, the first low-profile portion 2214 and the second low-profile portion 2215 are both opposite to one side of the inner wall of the adapter socket 120 provided in the receiving cavity 110. It should be understood that when the adapter is pulled out from the adapter socket 120, the first low-profile portion 2214 and the second low-profile portion 2215 can limit the rotation position of the rotating member 220 to prevent the rotating member 220 from rotating excessively.

[0062] Combination Figure 3 and Figure 5 As shown, in some embodiments, when the second protrusion 2212 is inserted into the adapter socket 120, both the first low-profile portion 2214 and the second low-profile portion 2215 are in contact with one side of the inner wall of the receiving cavity 110 where the adapter socket 120 is located. It can be understood that the first low-profile portion 2214 and the second low-profile portion 2215 ensure that the two sides of the second protrusion 2212 form a seal with the inner wall of the receiving cavity 110 where the adapter socket 120 is located, thereby improving the sealing effect of the sealing member 221 on the adapter socket 120 and further preventing impurities from entering the receiving cavity 110 from the two sides of the second protrusion 2212.

[0063] In some embodiments, when the rotating member 220 is in its initial state, the surface of the rotating member 220 facing away from the receiving cavity 110 is further away from the inner edge of the adapter socket 120. This ensures that the rotating member 220 can close the adapter socket 120, thereby improving the sealing performance of the adapter socket 120. In some instances, when the rotating member 220 is in its initial state, the surface of the rotating member 220 facing away from the receiving cavity 110 is flush with the outer edge of the adapter socket 120. It should be noted that the surface of the rotating member 220 facing away from the receiving cavity 110 can be the top surface of the second protrusion 2212. With this configuration, when no adapter is inserted into the adapter socket 120, the surface of the housing 100 with the adapter socket 120 appears to be flat rather than as a slot or opening, thereby improving both the sealing performance of the adapter socket 120 to prevent impurities from entering the housing 100 and the aesthetics of the power rail.

[0064] Combination Figure 1 and Figure 5 As shown, in some embodiments, the width of the second protrusion 2212 is equal to the width of the adapter socket 120. With this configuration, when the rotating member 220 is in its initial state, it can be ensured that the second protrusion 2212 completely seals the adapter socket 120, further improving the sealing effect of the rotating member 220 on the adapter socket 120.

[0065] like Figure 6 As shown, in some embodiments, the protective door 200 further includes a base 230 and an elastic telescopic member 240. The base 230 is fixed inside the receiving cavity 110. The base 230 and the rotating member 220 are located on opposite sides of the displacement member 210, and the two ends of the elastic telescopic member 240 abut against the base 230 and the displacement member 210, respectively. The displacement member 210 can move along the extension and retraction direction of the elastic telescopic member 240. Thus, when the adapter is inserted into the receiving cavity 110 from the adapter socket 120, the displacement member 210 can move towards the base 230 under the pushing force of the rotating member 220, and the elastic telescopic member 240 is compressed under the pressure of the displacement member 210. Driven by the displacement member 210, the rotating member 220 can move away from the insertion path to ensure that the adapter can be smoothly inserted into the receiving cavity 110. As the adapter is gradually pulled out of the receiving cavity 110, the pressure exerted by the adapter on the rotating member 220 decreases. At this time, the thrust exerted by the rotating member 220 on the displacement member 210 decreases. Under the elastic restoring force of the elastic telescopic member 240, the elastic telescopic member 240 can push the displacement member 210 towards the insertion path. Driven by the displacement member 210, the rotating member 220 also moves synchronously towards the insertion path to its initial position opposite to the adapter socket 120. When the adapter is completely disengaged from the adapter socket 120, the second protrusion 2212 on the rotating member 220 can then engage with the adapter socket 120 to close it. It can be understood that by providing the elastic telescopic member 240, the displacement member 210 and the rotating member 220 can achieve automatic reset. In some embodiments, the extension direction of the elastic telescopic member 240 is parallel to the movement direction of the displacement member 210. This ensures that the displacement member 210 moves smoothly without deviation. It should be noted that the elastic telescopic component 240 can be, for example, a cylindrical telescopic spring, a spring pin, or an elastic telescopic rod. (See attached image) Figure 6 The elastic telescopic component 240 shown is a columnar spring.

[0066] It should be understood that when the adapter is inserted into the receiving cavity 110 through the adapter socket 120, the rotating member 220 can rotate into the receiving cavity 110 under the pressure of the adapter under the action of the torsion spring 213. Furthermore, under the action of the elastic telescopic member 240, as the adapter is inserted deeper, the rotating member 220 can drive the displacement member 210 to move, so that the rotating member 220 avoids the insertion path of the adapter, allowing the adapter to be smoothly inserted into the receiving cavity 110 to draw power. When the adapter is gradually pulled out of the housing 100, under the action of the torsion spring 213, the pressure of the adapter on the rotating member 220 gradually decreases, allowing it to rotate in the opposite direction. At this time, the thrust on the displacement member 210 from the rotating member 220 also gradually decreases, so under the action of the elastic telescopic member 240, the displacement member 210 can move towards the direction closer to the insertion path, and the displacement member 210 can drive the rotating member 220 to move to the initial position of closing the adapter socket 120. As can be seen from the above, by setting a protective door 200 that can both rotate and slide inside the housing 100 of the power rail, not only can the insertion path be better avoided when the power taking part of the adapter is inserted into the receiving cavity 110, but it can also be restored to the position of closing the adapter socket 120 in time when the adapter is pulled out.

[0067] like Figure 7 As shown, in some embodiments, the seat member 230 has a first limiting groove 232 with an opening facing the rotating member 220, and the two ends of the elastic telescopic member 240 abut against the bottom of the first limiting groove 232 and the end face of the displacement member 210 facing away from the rotating member 220, respectively.

[0068] Combination Figure 6 and Figure 7 As shown, in some embodiments, the bottom of the first limiting groove 232 is connected to a limiting post 233. The elastic telescopic member 240 is a columnar telescopic spring, with one end of the elastic telescopic member 240 sleeved on the limiting post 233, and the other end abutting against the end face of the displacement member 210 opposite to the rotating member 220. By setting the limiting post 233, the telescopic direction of the elastic telescopic member 240 can be limited, ensuring that the displacement member 210 can move smoothly along the telescopic direction of the elastic telescopic member 240.

[0069] like Figure 7 As shown, in some embodiments, either the base member 230 or the displacement member 210 is provided with at least one slide rail 216, and the other is provided with at least one slide groove 231. The slide rail 216 slides in conjunction with the corresponding slide groove 231 to allow the displacement member 210 to move relative to the base member 230. This arrangement prevents the displacement member 210 from detaching from the base member 230, thus allowing the displacement member 210 to be relatively stably mounted on the housing 100, improving the reliability and stability of the protective door 200.

[0070] like Figure 6As shown, in some embodiments, the side of the seat member 230 near the rotating member 220 includes a third protrusion 234 and a fourth protrusion 235 disposed opposite to each other. A second notch 236 facing the rotating member 220 is formed between the third protrusion 234 and the fourth protrusion 235. The inner walls of the third protrusion 234 and the fourth protrusion 235 are respectively provided with grooves 231. The displacement member 210 is located between the third protrusion 234 and the fourth protrusion 235. The displacement member 210 includes a first sidewall 2191 and a second sidewall 2192. The first sidewall 2191 faces the third protrusion 234, and the second sidewall 2192 faces the fourth protrusion 235. The first sidewall 2191 and the second sidewall 2192 are respectively provided with slide rails 216 extending along the moving direction of the displacement member 210. The slide rails 216 are located in the opposite grooves 231 and slide in cooperation with the corresponding grooves 231. It should be understood that the cooperation between the slide rail 216 and the slide groove 231 prevents the displacement member 210 from disengaging from the base member 230, thereby improving the reliability and stability of the protective door 200. It should be noted that the slide rail 216 and the corresponding slide groove 231 can be interchanged. For example, a slide groove 231 can be provided on the displacement member 210, and a slide rail 216 corresponding to the slide groove 231 can be provided on the base member 230.

[0071] like Figure 2 As shown, in some embodiments, a limiting member 237 is connected to the side of the base member 230 facing away from the plane of the adapter socket 120, and the limiting member 237 extends along the extending direction of the adapter socket 120. A second limiting groove 111 with an opening facing the plane of the adapter socket 120 is provided in the receiving cavity 110. The limiting member 237 is engaged in the second limiting groove 111, thereby stably fixing the base member 230 in the receiving cavity 110.

[0072] like Figure 2As shown, in some embodiments, the inner wall of the receiving cavity 110 opposite to the adapter socket 120 is provided with a support rib 112, which extends along the extending direction of the adapter socket 120. The second limiting groove 111 includes a first groove wall 1111 and a second groove wall 1112 disposed opposite to each other, with the second groove wall 1112 located between the support rib 112 and the first groove wall 1111. The distance between the top of the support rib 112 and the plane where the adapter socket 120 is located is equal to the distance between the top of the groove of the second groove wall 1112 and the plane where the adapter socket 120 is located. The top of the support rib 112 and the top of the groove of the second groove wall 1112 respectively abut against the side of the seat member 230 opposite to the adapter socket 120. It should be noted that the second groove wall 1112 and the support rib 112 can provide stable support for the base component 230, thereby ensuring that the base component 230 is in a horizontal state. Consequently, the displacement component 210, which slides with the base component 230, can move smoothly in the horizontal direction. The rotating component 220 connected to the displacement component 210 can also be in a horizontal state in the initial state. In other words, when the adapter is not inserted into the adapter socket 120, the protective door 200 can be stably in a horizontal state, preventing the protective door 200 from pushing up the wall where the adapter socket 120 is located. As a result, the housing 100 is not easily deformed, thus improving the reliability and stability of the power rail.

[0073] Combination Figure 7 As shown, in some embodiments, the protective door 200 includes multiple base members 230, multiple displacement members 210, and multiple rotating members 220. The multiple base members 230 can be integrally formed. The multiple displacement members 210 are arranged side by side and spaced apart along the extension direction parallel to the adapter socket 120. Each displacement member 210 corresponds one-to-one with a rotating member 220, and one base member 230 can be slidably connected to multiple displacement members 210 simultaneously. With this arrangement, each rotating member 220 can rotate independently. That is, only the rotating member 220 subjected to adapter pressure will rotate, rather than all rotating members 220 rotating synchronously. This avoids all rotating members 220 rotating synchronously every time an adapter is plugged in or unplugged, thus preventing damage from excessive rotation and improving the reliability of the protective door 200. In addition, since only the rotating part 220 subjected to adapter pressure rotates, while other rotating parts 220 not subjected to adapter pressure are in the initial state corresponding to the closed adapter socket 120, the opening area of ​​the adapter socket 120 can be reduced, reducing the entry of external impurities into the housing 100, providing better protection for the devices inside the housing 100, and improving the safety of the power rail.

[0074] As can be seen from the above, the power rail provided in this embodiment integrates a protective door 200 with both rotation and movement functions. This not only provides space for the adapter to be inserted into the adapter socket 120 on the housing 100 when the adapter's power-taking part is inserted, but also promptly returns to its initial position, sealing the adapter socket 120, when the adapter is pulled out of the housing 100. This allows the adapter socket 120 to be sealed promptly when the adapter is pulled out, preventing external impurities from entering the housing 100 through the adapter socket 120, thereby protecting the components inside the housing 100 and improving the safety of the power rail.

[0075] On the other hand, combining Figures 1 to 7 As shown, this application embodiment also provides a track socket, which includes at least one adapter (not shown in the figure) and the power track described in any of the above claims. The power-taking part of the adapter can be inserted into the housing 100 through the adapter socket 120. It should be noted that the power track installed in the track socket provided in this application embodiment has the same composition and function as the power track described in any one of the above applications, so it will not be described again here. Since the power track is equipped with a protective door 200 that integrates rotation and movement functions, when the power-taking part of the adapter is inserted into the housing 100 through the adapter socket 120, the rotating part 220 of the protective door 200 can first rotate into the receiving cavity 110, and then push the displacement part 210 to move in a direction that avoids the insertion path, thereby providing an insertion channel for the power-taking part of the adapter. When the power-taking part of the adapter is pulled out of the housing 100, the rotating part 220 of the protective door 200 can rotate in the opposite direction. At the same time, the displacement member 210 can push the rotating part 220 to move closer to the insertion path, so that the rotating part 220 returns to the initial position of closing the adapter socket 120. The rotating part 220 that closes the adapter socket 120 can prevent external impurities from entering the housing from the adapter socket 120, thereby better protecting the components inside the power rail, avoiding damage to the components by external impurities, improving the safety of the power rail, and thus improving the safety and service life of the rail socket.
