Therefore, the track socket is popular in the market because of its flexible use.

[0004] The housing of the power rail has a plug interface for inserting the adapter. Dust can easily enter the interior of the power rail through the plug interface, causing wear to the internal conductive plate and reducing the service life of the power rail. Utility Model Content

[0005] The present disclosure provides a power rail and a rail socket, which can overcome the problem of short service life of the power rail in the related art, and can also reduce the cost of the power rail and improve the assembly efficiency of the power rail. The technical solution is as follows:

[0006] In a first aspect, a power rail is provided, the power rail comprising a housing and a protective door;

[0007] The panel of the housing has a plug-in port, and the protective door is located in the housing and on a first side of the plug-in port along a width direction, and shields the plug-in port;

[0008] When the adapter is inserted into the plug port, the protection door moves to no longer block the plug port, and when the adapter is removed from the plug port, the protection door returns to block the plug port.

[0009] In a possible implementation, the power rail further includes a fixed door, which is distributed along the length direction of the plug interface and is fixed on a second side in the width direction of the plug interface;

[0010] The fixed door is lower than or flush with a second edge of the plug-in port, and the second edge is an opening edge of the plug-in port away from the protective door.

[0011] In a possible implementation, when the protective door blocks the plug port, the protective door abuts against the fixed door.

[0012] In a possible implementation manner, the fixed door is inclined relative to the panel and inclined toward the protective door.

[0013] In a possible implementation, the protection door includes a horizontal portion and a guide slope, and the horizontal portion is located between the panel and the electrode channel of the housing;

[0014] When the adapter is not inserted into the plug interface, the position of the guide ramp is opposite to the position of the plug interface and is inclined in a direction away from the plug interface, and the end of the guide ramp is flush with or extends beyond the second edge of the plug interface, which is the opening edge of the plug interface away from the protective door.

[0015] In a possible implementation, the end of the guide ramp extends into the electrode channel opening of the electrode channel, and when the adapter is inserted into the plug port, the inner surface of the guide ramp contacts the opening edge of the electrode channel opening.

[0016] In a possible implementation, an outer surface of the protection door facing the plug interface has a first anti-reverse plug-in structure, and the first anti-reverse plug-in structure matches the second anti-reverse plug-in structure of the adapter;

[0017] When the power taking part of the adapter is inserted into the plug port and the first anti-reverse plugging structure and the second anti-reverse plugging structure are located on different sides of the power taking part, the protection door moves to no longer block the plug port.

[0018] In a possible implementation, the first anti-reverse insertion structure has a limiting surface facing the plug interface, and the limiting surface of the first anti-reverse insertion structure matches the limiting surface of the second anti-reverse insertion structure;

[0019] When the power taking part of the adapter is inserted into the plug port and the first anti-reverse plug-in structure and the second anti-reverse plug-in structure are located on the same side of the power taking part, the limiting surface of the first anti-reverse plug-in structure contacts the limiting surface of the second anti-reverse plug-in structure, and the protective door keeps covering the plug port.

[0020] In a possible implementation, the limiting surfaces of the first anti-reverse insertion structure are parallel to the panel of the power rail, wherein the limiting surface of the second anti-reverse insertion structure is parallel to the panel of the adapter.

[0021] In a possible implementation, the first anti-reverse insertion structure has at least one tooth structure;

[0022] When the power supply part of the adapter is inserted into the plug port and the first anti-reverse plug-in structure and the second anti-reverse plug-in structure are located on the same side of the power supply part, at least one tooth structure of the first anti-reverse plug-in structure is engaged with at least one tooth structure of the second anti-reverse plug-in structure, and the protective door keeps covering the plug port.

[0023] In a possible implementation manner, the first anti-reverse insertion structure and the second anti-reverse insertion structure are both L-shaped notches.

[0024] In a possible implementation, the shell is an integrated shell, which is manufactured through an integrated molding process.

[0025] In a possible implementation, the protective door is an elastic and retractable protective door, and when the adapter is pulled out of the plug interface, the protective door is reset to cover the plug interface under the action of elasticity.

[0026] In a second aspect, a track socket is provided, the track socket comprising an adapter and the power track according to the first aspect, the adapter being pluggably connected to the power track.

[0027] In a third aspect, a track socket is provided, comprising an adapter and a power track with the first anti-reverse plug-in structure as described in the first aspect, the adapter having a power taking part inserted into the plug interface, and one side of the power taking part is provided with the second anti-reverse plug-in structure at the bottom position.

[0028] In this embodiment, the power rail includes a protective door. When the adapter is not inserted into the plug interface, the protective door shields the plug interface and seals the plug interface. When the adapter is inserted into the plug interface, the adapter applies force to the protective door, pushing the protective door to one side of the plug interface, and the protective door no longer shields the plug interface, so that the adapter contacts the conductive plate in the electrode channel. When the adapter is pulled out of the plug interface, the protective door resets and moves to shield the plug interface. Furthermore, the power rail can improve the safety of the power rail by shielding the plug interface with the protective door, and achieve the effect of waterproofing and dust removal to extend the service life of the power rail.

[0029] Moreover, since there is only one protective door, a single protective door is used to shield the plug interface. Compared with the solution of using two left and right protective doors, one less protective door is used, which saves the cost of the power rail, simplifies the assembly process of the power rail, and improves the assembly efficiency.

[0048] The above drawings show clear embodiments of the present disclosure, which will be described in more detail below. These drawings and text descriptions are not intended to limit the scope of the present disclosure in any way, but to illustrate the concepts of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0049] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0050] This embodiment provides a power rail, which is specifically used in a rail socket, wherein the rail socket is a new type of socket product, which mainly includes a power rail and an adapter in structure. The power rail is installed on a wall or embedded in a desktop, and the adapter is plugged into the power rail in a pluggable manner and can be inserted at any position of the power rail. The adapter has a socket for drawing electricity, and the plug of the electrical device can draw electricity by inserting it into the socket of the adapter.

[0051] The number of adapters of the track socket can be flexibly increased or decreased according to demand, and the position can be flexibly adjusted according to the position of the electrical devices, without having to worry about the short power cord of the electrical devices. Moreover, compared with ordinary sockets, the track socket is safer and more beautiful. Therefore, the track socket is widely popular in the market due to the above advantages.

[0052] The power rail mainly includes a housing 1, a conductive plate, an insulating bracket and a junction box. The housing 1 serves as the outer shell of the power rail and plays a protective role. The material of the housing 1 can be an aluminum profile. Figure 1 As shown, the panel 11 of the housing 1 has a plug-in interface 111 , and the housing 1 has an electrode channel 121 .

[0053] In this way, the conductive plate and the insulating bracket are both installed in the electrode channel 121, and the conductive plate is clamped by the insulating bracket, and the junction box is installed at one end of the housing 1, wherein the junction box has a terminal, and the terminal is used to connect the conductive plate to the power line in the wall. The power-taking part of the adapter passes through the plug interface 111, extends into the electrode channel 121, and contacts and electrically connects with the conductive plate in the electrode channel 121. The top of the adapter has a socket for taking power, and the plug of the electrical device can be inserted into the socket of the adapter to take power.

[0054] However, since the plug interface 111 of the power rail is open to the outside, it is unsafe and easy for water and dust to enter. Water ingress may cause safety accidents, and dust ingress may wear the conductive plate in the electrode channel 121. Both water ingress and dust ingress will reduce the service life of the power rail.

[0055] Therefore, in order to prevent dust, block foreign matter and improve appearance, the power rail may further include a protection door, which is located in the housing and is used to cover the plug interface 111 .

[0056] In order to facilitate the insertion of the adapter into the plug port 111, the protective door currently on the market is usually a soft rubber sealing strip that is easily deformed by compression. However, after long-term use, such protective door will undergo plastic deformation, collapse, and fail to close to achieve a sealing effect. This is especially likely to occur in a kitchen environment with oil smoke and salt stains. Moreover, the protective door will age and harden faster in an environment with oil smoke and salt stains, which will also affect the insertion and removal of the adapter and its movement along the plug port.

[0057] The protective door of the power rail in this embodiment is made of plastic, which has the characteristics of good contact, not easy to age and not easy to deform, and can extend the service life of the power rail and enhance the user experience.

[0058] The structural features of the power rail are described below.

[0059] Regarding the structural features of the housing 1, such as Figure 1 and Figure 2 As shown, the shell 1 includes a panel 11, a bottom plate 12 and two side plates 13. The panel 11 and the bottom plate 12 are opposite to each other and connected by a connecting plate 14. The two side plates 13 are respectively located on both sides of the panel 11 along the width direction.

[0060] Continue to refer Figure 1 As shown, the panel 11 has an insertion port 111 arranged along the length direction, wherein the reference Figure 2 As shown, the center line of the plug port 111 and the center line of the panel 11 may coincide with each other, that is, the plug port 111 is located at the center line position of the panel 11 .

[0061] like Figure 2 And refer to Figure 1 As shown, the bottom plate 12 may be in a plate shape, and the upper surface of the bottom plate 12 , that is, the surface facing the panel 11 , has an electrode channel 121 .

[0062] The position of the electrode channel 121 is opposite to the position of the plug interface 111, so that the power receiving part of the adapter can be inserted into the plug interface 111, enter the electrode channel 121, and be electrically connected to the conductive plate in the electrode channel 121. In order to enable the adapter to enter the electrode channel 121, as shown in FIG. Figure 1 and Figure 2 As shown, the top wall of the electrode channel 121 facing the panel 11 has an electrode channel opening 122, and the position of the electrode channel opening 122 is opposite to the position of the plug-in port 111, as shown in FIG. Figure 2 As shown, the width of the electrode channel opening 122 is greater than the width of the insertion opening 111 .

[0063] In one example, since the power rail further includes a protection door, the protection door is installed in the housing 1, so the housing 1 also has an installation chamber 10 for the protection door, such as Figure 2 As shown, the panel 11 , the connecting plate 14 , the bottom plate 12 and the electrode channel 121 on the same side of the plug-in port 111 form an installation chamber for the protection door 2 , and the protection door 2 is installed in the installation chamber 10 .

[0064] Continue to refer Figure 2 As shown, the housing 1 can be an integrated housing, and the panel 11, the bottom plate 12, the side plate 13, the connecting plate 14 and the electrode channel 121 are processed by an integrated molding process. Of course, the housing 1 can also be a split housing, the panel 11 and the two side plates 13 are integrally formed, and the panel 11 and the bottom plate 12 can be pre-fixed by snapping and then fixed by screws.

[0065] The above is an introduction to the structural features of the housing 1 , and this embodiment does not specifically limit the specific structural features of the housing 1 .

[0066] The features of the protection door 2 are described below.

[0067] like Figure 3 As shown, there is one protective door 2, which is arranged on the left or right side of the plug interface 111 along the length direction of the plug interface 111. Therefore, the power rail is a power rail with a single protective door.

[0068] Continue to refer Figure 3 As shown, the protection door 2 is located in the housing 1 and is located on a first side (ie, Figure 3 The right side of the figure) and shields the plug interface 111. Figure 4 As shown, when the adapter 100 is inserted into the plug port 111 and inserted to the bottom, the protection door 2 moves to no longer block the plug port 111 , and when the adapter 100 is pulled out of the plug port 111 , the protection door 2 returns to block the plug port 111 .

[0069] The adapter is inserted into the plug port 111 , that is, the power taking part 101 of the adapter 100 passes through the plug port 111 and the electrode channel opening 122 in sequence and extends into the electrode channel 121 .

[0070] The protection door 2 blocks the plug port 111 , that is, the protection door 2 is located between the plug port 111 and the electrode channel port 122 , blocking the connection between the plug port 111 and the electrode channel port 122 .

[0071] It can be seen that the power rail includes a protective door. When the adapter is not inserted into the plug interface, the protective door blocks the plug interface and plays a role of sealing the plug interface. When the adapter is inserted into the plug interface, the adapter applies force to the protective door, pushing the protective door to one side of the plug interface, and the protective door no longer blocks the plug interface, so that the adapter contacts the conductive plate in the electrode channel. When the adapter is pulled out of the plug interface, the protective door resets and moves to a position that blocks the plug interface. Furthermore, the power rail can improve the safety of the power rail by shielding the plug interface with the protective door, and achieve the effect of waterproofing and dust release to extend the service life of the power rail.

[0072] Moreover, since there is only one protective door, a single protective door is used to shield the plug interface. Compared with the solution of using two left and right protective doors, one less protective door is used, which saves the cost of the power rail, simplifies the assembly process of the power rail, and improves the assembly efficiency.

[0073] In one example, if Figure 3 As shown, the power rail further includes a fixed door 3, which is located on the inner surface of the panel 11, on the second side (i.e. Figure 3 ), and along the length direction of the plug interface 111. Figure 3 As shown, the edge of the fixed door 3 close to the protective door 2 is slightly lower than or flush with the second edge of the plug port 111 , wherein the second edge of the plug port 111 is the edge of the plug port 111 away from the protective door 2 .

[0074] The length of the fixed door 3 is greater than or equal to the length of the protective door 2 .

[0075] like Figure 3 And refer to Figure 4 As shown, the fixed door 3 provides support for the insertion of the adapter 100 on one hand, preventing the adapter 100 from tilting due to the force of only one-side protective door. On the other hand, the fixed door 3 can also prevent small objects such as wires from being inserted into the electrode channel 121.

[0076] Therefore, when the adapter 100 is being inserted, both left and right sides of the power taking portion 101 of the adapter 100 are subjected to force, so that the adapter is vertically inserted into the electrode channel 121 .

[0077] In one example, continue to refer to Figure 3 As shown, the fixed door 3 can be inclined relative to the panel 11, such as the end of the fixed door 3 away from the inner surface of the panel 11 is inclined toward the protective door 2 and extends into the electrode channel opening 122 of the electrode channel 121.

[0078] refer to Figure 3 As shown, in the solution where the fixed door 3 is inclined, the end of the fixed door 3 away from the panel 11 is slightly lower than or flush with the second edge of the plug port 111 along the width direction of the plug port 111. In this way, although the fixed door 3 is immovable, it is slightly lower than or flush with the second edge of the plug port 111, so the fixed door 3 will not interfere with the insertion of the adapter.

[0079] In one example, if Figure 3 As shown, the protective door 2 includes a horizontal portion 225 and a guide slope 226. The horizontal portion 225 is located between the panel 11 and the top wall of the electrode channel 121. When the adapter 100 is not inserted into the plug interface 111, the guide slope 226 is located opposite to the plug interface 111, and the end of the guide slope 226 is flush with or extends out from the second edge of the plug interface 111, and the second edge of the plug interface 111 is away from the opening edge of the protective door 2.

[0080] The included angle between the horizontal portion 225 and the guide slope 226 is an obtuse angle.

[0081] In one example, the guide slope 226 of the door sheet 22 plays a guiding role when the adapter is inserted into the electrode channel 121 through the plug interface 111, so refer to Figure 3 As shown, the end of the guide ramp 226 extends into the electrode channel opening 122 of the electrode channel 121.

[0082] In this way, Figure 3 As shown, when the adapter 100 is not inserted into the plug port 111, the guide slope 226 of the protection door 2 blocks the plug port 111, and the end of the fixed door 3 away from the panel 11 abuts or nearly abuts against the end of the guide slope 226 of the protection door 2. When the power supply portion 101 of the adapter 100 is inserted into the plug port 111, and the adapter 100 continues to be inserted in the direction of the electrode channel 121, the protection door can be smoothly moved to no longer block the plug port 111 under the guidance of the guide slope 226.

[0083] In one example, reference Figure 3As shown, the thickness of the horizontal portion 225 of the protective door 2 is slightly smaller than the distance between the panel 11 and the top wall 120 of the electrode channel 121. The horizontal portion 225 is limited between the panel 11 and the top wall 120 of the electrode channel 121, which can prevent the protective door 2 from tilting and deforming during reciprocating movement.

[0084] In one example, if Figure 3 As shown, when the adapter 100 is not inserted into the plug port 111, the end of the guide ramp 226 extends into the electrode channel opening 122 of the electrode channel 121, and when the adapter 100 is inserted into the plug port 111, the end of the guide ramp 226 extends into the electrode channel opening 122 of the electrode channel 121. Figure 4 As shown, the inner surface of the guide slope 226 contacts the opening edge of the electrode channel opening 122 of the electrode channel 121 .

[0085] It can be seen that the width of the electrode channel opening 122 of the electrode channel 121, on the one hand, satisfies the movement of the protection door 2, and on the other hand, makes the top wall 120 of the electrode channel 121, corresponding to the horizontal part 225, wide enough to limit the horizontal part 225 of the protection door together with the panel 11.

[0086] In one example, if Figure 5 As shown, the guide slope 226 of the protection door 2 has a first anti-reverse insertion structure 227 on the outer surface facing the plug interface 111. The first anti-reverse insertion structure 227 matches the second anti-reverse insertion structure 102 of the adapter 100. Figure 3 As shown, it is arranged at the bottom position of one side of the power taking part 101 of the adapter 100. When the adapter 100 is inserted into the plug interface 111 and the first anti-reverse plugging structure 227 and the second anti-reverse plugging structure 102 are located opposite to each other, Figure 4 As shown, when the first anti-reverse insertion structure 227 and the second anti-reverse insertion structure 102 are located on the opposite sides of the power taking part 101 (one is on the left side of the power taking part 101, and the other is on the right side of the power taking part 101), the adapter 100 can continue to be inserted, and the protective door 2 can be pushed open, and the protective door 2 can be moved to no longer block the plug interface 111. When the adapter 100 is inserted into the plug interface 111 and the first anti-reverse insertion structure 227 and the second anti-reverse insertion structure 102 are in the same position, as shown in FIG. Figure 3 As shown in the figure, when they are located on the same side of the power taking part 101 (both on the left side of the power taking part 101, or both on the right side of the power taking part 101), when the power taking part 101 of the adapter 100 is inserted until the first anti-reverse insertion structure 227 contacts the second anti-reverse insertion structure 102, the power taking part 101 cannot be further inserted, and thus the protective door 2 cannot be pushed open.

[0087] In one example, the first anti-reverse plug-in structure 227 and the second anti-reverse plug-in structure 102 both have limiting surfaces, and the limiting surfaces of the two cooperate with each other. For example, the limiting surface of the first anti-reverse plug-in structure 227 is parallel to the panel 11, and the limiting surface of the second anti-reverse plug-in structure 102 is parallel to the panel of the adapter 100 (where the panel has a jack for inserting the plug pin of the plug). When the adapter 100 is connected as shown in FIG. Figure 3 When the adapter 100 is inserted into the power rail in reverse, the limiting surface of the second anti-reverse insertion structure 102 contacts the limiting surface of the first anti-reverse insertion structure 227, so that the limiting surface of the first anti-reverse insertion structure 227 restricts (i.e. interferes) the adapter 100 from continuing to be inserted downward, and the protective door keeps covering the plug interface, so that the adapter cannot be inserted into the power rail to draw power.

[0088] In one example, reference Figure 3 As shown, the first anti-reverse insertion structure 227 and the second anti-reverse insertion structure 102 can be L-shaped notches, such as Figure 3 As shown, an L-shaped notch may be provided at the connection between the bottom and the side of the power taking portion 101 of the adapter 100 , and an L-shaped notch may also be provided on the outer surface of the guide slope 226 .

[0089] Among them, the first anti-reverse insertion structure 227 and the second anti-reverse insertion structure 102 are both L-shaped notches, so, refer to Figure 3 As shown, the limiting surface of the first anti-reverse insertion structure 227 is the transverse surface of the L-shaped notch, and the limiting surface of the second anti-reverse insertion structure 102 is the transverse surface of the L-shaped notch.

[0090] In another example, the first anti-reverse plug-in structure 227 may also have at least one tooth structure, and the second anti-reverse plug-in structure 102 may have at least one tooth structure. For example, the number of tooth structures included in the two is the same. When the adapter 100 is reversely plugged into the power rail, at least one tooth structure of the second anti-reverse plug-in structure 102 engages with at least one tooth structure of the first anti-reverse plug-in structure, thereby interfering with the adapter 100 from continuing to be inserted downward, and the protective door keeps covering the plug interface, thereby preventing the adapter from being reversely plugged in and unable to draw power.

[0091] The first anti-reverse plug-in structure 227 has a tooth structure, for example, the first anti-reverse plug-in structure 227 is an L-shaped notch, and the first anti-reverse plug-in structure 227 has multiple tooth structures, for example, the multiple tooth structures are stepped. Similarly, the second anti-reverse plug-in structure 102 has a tooth structure, for example, the second anti-reverse plug-in structure 102 is an L-shaped notch, and the second anti-reverse plug-in structure 102 has multiple tooth structures, for example, the multiple tooth structures are stepped.

[0092] It can be seen that the protective door 2 has a first anti-reverse plug-in structure 227, and the adapter has a second anti-reverse plug-in structure 102, which can prevent the adapter 100 from being plugged in reverse. The adapter 100 cannot be powered when it is plugged in reverse, and can only be powered when it is plugged in forward. Because when the adapter is plugged in forward, the positive pole of the adapter is connected to the positive pole of the power rail, and the negative pole of the adapter is connected to the negative pole of the power rail. Figure 3 If the adapter 100 is inserted into the power rail in the state shown in FIG. Figure 4 The state shown is inserted into the power rail, which is a positive insertion.

[0093] In one example, the protective door 2 can be an elastic retractable protective door. When the adapter is inserted into the socket, the spring inside the protective door 2 is compressed, and the protective door 2 moves to no longer block the electrode channel opening 122. When the adapter is unplugged, the protective door 2 is reset under the action of elasticity and moves to block the electrode channel opening 122.

[0094] The structural features of the protection door 2 are described below. Figure 6 As shown, the protection door 2 includes a door seat 21, a door piece 22 and a return spring 23. The door piece 22 is used to block the plug interface 111, the door seat 21 is used as a fixing member to install the door piece 22 in the housing 1, and the return spring 23 is installed between the door seat 21 and the door piece 22. The expansion and contraction direction of the return spring 23 is parallel to the moving direction of the door piece 22, and is used to return the door piece 22 to block the plug interface 111.

[0095] In one example, the protective door 2 is installed in the housing 1 through the door seat 21, for example, Figure 2 As shown, the upper surface of the bottom plate 12 has a first rib 123 between the connecting plate 14 and the electrode channel 121, and a first slot 125 is formed between the first rib 123 and the connecting plate 14. Figure 3 As shown, the door seat 21 can be stuck in the first slot 125 , and the door seat 21 is specifically stuck between the first rib 123 and the connecting plate 14 .

[0096] The protective door 2 is located in the housing 1. When the adapter is inserted into the plug interface 111, Figure 4 As shown, the door sheet 22 moves to the side of the plug-in port 111, and when the adapter is pulled out from the plug-in port 111, as shown in FIG. Figure 3 As shown, the door piece 22 moves to block the plug-in port 111 under the elastic action of the return spring 23 .

[0097] In one example, the material of the protection door 2 can be plastic. For example, the material of the door seat 21 and the door sheet 22 can both be plastic. Compared with rubber, plastic is harder, less likely to deform, less likely to age, and less susceptible to oil smoke and salt stains. Thus, this protection door can extend the service life of the power rail and enhance the user experience.

[0098] In one example, when the door sheet 22 reciprocates relative to the door seat 21, in order to prevent the door sheet 22 from falling off the door seat 21, accordingly, Figure 7 As shown, the door seat 21 has a first limiting structure 211, such as Figure 8 As shown, the door piece 22 has a second limiting structure 221. In this way, the door piece 22 can be buckled on the door seat 21 through the cooperation of the first limiting structure 211 and the second limiting structure 221.

[0099] In order to enable the door piece 2 to switch between shielding the plug-in port 111 and exposing the plug-in port 111 , the door piece 22 can also move relative to the door base 21 accordingly.

[0100] Regarding the specific structures of the first limiting structure 211 and the second limiting structure 221, for example, the first limiting structure 211 may be a strip-shaped opening or a strip-shaped groove, and the second limiting structure 221 may be a protruding structure. Figure 3 As shown, the first limiting structure 211 is a strip-shaped opening, and the second limiting structure 221 is a protruding structure.

[0101] Alternatively, the first limiting structure 211 is a protruding structure, and the second limiting structure 221 is a strip-shaped opening or a strip-shaped groove.

[0102] In this way, the door sheet 22 can be buckled onto the door seat 21 by the protrusion structure being located in the strip-shaped opening, or by the protrusion structure being located in the strip-shaped groove.

[0103] Since the door leaf 22 can also move relative to the door seat 21, in order to provide room for the movement of the door leaf 22, the strip direction of the strip opening or the strip groove is parallel to the moving direction of the door leaf 22. In this way, the movement of the door leaf 22 relative to the door seat 21 can be satisfied, and the door leaf 22 and the door seat 21 can be snapped together, thereby preventing the door leaf 22 from separating from the door seat 21.

[0104] The present embodiment does not limit the specific structural forms of the first limiting structure 211 and the second limiting structure 221 . The first limiting structure 211 can be a strip-shaped opening, and the second limiting structure 221 can be a protruding structure.

[0105] In an example, the length of the first limiting structure 211 may be equal to the moving stroke of the door panel 22 , or may be slightly greater than the moving stroke of the door panel 22 .

[0106] In this way, when the door panel 22 blocks the plug-in port 111, the second limiting structure 221 on the door panel 22 can contact or be close to contacting the edge of the first limiting structure 211 on the door seat 21. It can be seen that even if the elastic force of the reset spring 23 is relatively large, since the second limiting structure 221 is stuck on the edge of the first limiting structure 211, the door panel 22 will not separate from the door seat 21.

[0107] In one example, in order to form the first limiting structure 211 on the door seat 21, accordingly, as Figure 7 As shown, the first surface of the door seat 21 has a limiting cavity 210, and the first limiting structure 211 is an opening arranged on the wall of the limiting cavity 210. The first surface of the door seat 21 is also the surface facing the door sheet 22 and perpendicular to the moving direction of the door sheet 22.

[0108] In another example, another way to form the first limiting structure 211 on the door seat 21 may be that the first surface of the door seat 21 has a side wall perpendicular to the first surface, and the first limiting structure 211 may be an opening arranged on the side wall.

[0109] The present embodiment does not specifically limit the formation method of the first limiting structure 211 , and can be exemplified by forming the first limiting structure 211 on the cavity wall of the limiting cavity 210 .

[0110] In one example, in order to form the second limiting structure 221 on the door sheet 22, accordingly, as shown in FIG. Figure 8 As shown, the first end surface of the door sheet 22 has a limiting protrusion 220, and the second limiting structure 221 can be located on the side wall of the limiting protrusion 220. Figure 7 and Figure 8 As shown, the end of the limiting protrusion 220 extends into the limiting cavity 210 , and when inserted to the bottom, the second limiting structure 221 is stuck in the first limiting structure 211 .

[0111] The first end surface of the door piece 22 is an end surface facing the door seat 21 and perpendicular to the moving direction of the door piece 22 .

[0112] In one example, regarding the number of the first limiting structures 211 and the second limiting structures 221, as shown in FIG. Figure 7 and Figure 8 As shown, the number of the first limiting structures 211 and the number of the second limiting structures 221 are both two, the positions of the two first limiting structures 211 are relative to each other, the positions of the two second limiting structures 221 are relative to each other, one second limiting structure 221 is located in one first limiting structure 211, and the other second limiting structure 221 is located in the other first limiting structure 211.

[0113] Of course, the number of the first limiting structures 211 and the second limiting structures 221 may be greater, and the drawings in this embodiment may be illustrated with two first limiting structures 211 and two second limiting structures 221 .

[0114] In one example, when the second limiting structure 221 is separated from the first limiting structure 211, if the elastic force of the return spring 23 is relatively large, the door sheet 22 will be separated from the door seat 21. In order to avoid this situation, accordingly, Figure 8 As shown, the lower surface of the door piece 22 has a limiting rib 224 at a position near the end. When the protective door 2 blocks the plug interface 111 of the power rail, the limiting rib 224 is in contact or nearly in contact with the outer surface of the side wall of the electrode channel 121, restricting the door piece 22 from continuing to move toward the fixed door 3 under the action of the reset spring 23.

[0115] The lower surface of the door sheet 22 is the surface facing the electrode channel 121 of the power rail.

[0116] It can be seen that even if the second limiting structure 221 is detached from the first limiting structure 211, the side wall of the electrode channel 121 in the shell 1 blocks the limiting rib 224, which can prevent the door piece 22 from continuing to move away from the door seat 21. Then, the limiting rib 224 contacts the side wall of the electrode channel 121, which can further limit the door piece 22 from detaching from the door seat 21.

[0117] In one example, as described above, the return spring 23 is located between the door seat 21 and the door sheet 22, for example, Fig. 9 As shown, a spring column 212 is provided on the first surface of the door seat 21 and in the limiting cavity 210 , one end of the return spring 23 is sleeved outside the spring column 212 , and the other end abuts against the end surface of the limiting protrusion 220 .

[0118] In one example, the return spring 23 is sleeved outside the spring column 212, and the spring column 212 can ensure that the telescopic movement of the return spring 23 is kept in a straight line as much as possible. In addition, since the spring column 212 is located in the limiting cavity 210, the cavity wall of the limiting cavity 210 can also limit the telescopic movement of the return spring 23 to a certain extent, so that the telescopic movement is kept in a straight line as much as possible.

[0119] In one example, if Figure 8 As shown, the limiting protrusion 220 has a spring groove 222 with a notch facing the door seat 21 , and one end of the return spring 23 abuts against the bottom of the spring groove 222 .

[0120] like Figure 8As shown, the end of the return spring 23 abuts against the bottom of the spring groove 222. Compared with the case where the end of the return spring 23 abuts against the first end face of the limiting protrusion 220, the size of the protective door 2 along the length direction of the return spring 23 can be reduced, further reducing the space occupied by the protective door 2 in the shell 1.

[0121] In one example, if Figure 8 As shown, a first end surface of the door sheet 22 has a recessed groove 223 facing the door seat 21 , and the limiting protrusion 220 is located at the bottom of the recessed groove 223 .

[0122] This limiting protrusion 220 is located in the recessed groove 223 , which can reduce the size of the door sheet 22 along the length direction of the return spring 23 , thereby reducing the size of the protection door and reducing the space occupied by the protection door in the housing 1 .

[0123] In one example, since the plug interface 111 is arranged along the length direction of the power rail, that is, the plug interface 111 is in the shape of a long strip, the protection door 2 also needs to be in the shape of a long strip. Figure 6 As shown, the door seat 21 may be in the shape of an elongated strip, and the number of the limiting cavities 210 is multiple, and the multiple limiting cavities 210 are arranged in sequence along the length direction of the door seat 21. Figure 6 As shown, the number of door panels 22 and return springs 23 are also multiple, and the end of the limiting protrusion 220 of each door panel 22 extends into a limiting cavity 210, and each return spring 23 is located between the door seat 21 and a door panel 22. For example, each return spring 23 is sleeved outside the spring column 212 in a limiting cavity 210, and the end thereof rests against the bottom of a spring groove 222 of a door panel 22.

[0124] In one example, in order to avoid interference between two adjacent door panels 22 during movement, accordingly, as Figure 7 As shown, a plurality of partition ribs 213 are provided on the first surface of the door seat 21 and along the length direction, and a partition rib 213 is provided between two adjacent limiting cavities 210. In this way, when the limiting protrusion 220 of each door sheet 22 extends into a limiting cavity 210, the two adjacent door sheets 22 are blocked by the partition rib 213, so that the movement of the two adjacent door sheets 22 does not interfere with each other.

[0125] In this way, when an adapter is inserted into the plug port 111, the n door panels 22 are affected by the force of the adapter and move to the side of the plug port 111, while the door panels 22 that are not affected by the force of the adapter still keep blocking the plug port 111. When the adapter is pulled out of the plug port 111, the n door panels 22 are reset to the position blocking the plug port 111 under the elastic action of the connected reset springs 23.

[0126] Here, n is a positive integer. For example, n can be 1, or can be a value between 2 and 8. Of course, n can also be a value greater than 8.

[0127] In one example, the length of a door seat 21 may be adapted to the length of the plug port 111 , for example, the length of the door seat 21 may be approximately equal to the length of the plug port 111 .

[0128] In another example, since the length of the plug-in port 111 is relatively long, the number of door seats 21 can also be multiple, and the multiple door seats 21 are connected end to end in sequence along the length direction of the plug-in port 111.

[0129] For example, multiple door seats 21 are arranged on the left side of the plug port 111, and these multiple door seats 21 are arranged end to end along the length direction of the plug port 111. Multiple door seats 21 are arranged on the right side of the plug port 111, and these multiple door seats 21 are arranged end to end along the length direction of the plug port 111.

[0130] In this embodiment, the power rail includes a protective door. When the adapter is not inserted into the plug interface, the protective door shields the plug interface and seals the plug interface. When the adapter is inserted into the plug interface, the adapter applies force to the protective door, pushing the protective door to one side of the plug interface, and the protective door no longer shields the plug interface, so that the adapter contacts the conductive plate in the electrode channel. When the adapter is pulled out of the plug interface, the protective door resets and moves to shield the plug interface. Furthermore, the power rail can improve the safety of the power rail by shielding the plug interface with the protective door, and achieve the effect of waterproofing and dust removal to extend the service life of the power rail.

[0131] Moreover, the material of the protective door is plastic. Compared with a protective door made entirely of metal, the user can insert the adapter into the power rail or unplug the adapter from the power rail with less force, making the plugging and unplugging of the adapter smoother, and there will be no metal friction sound during the plugging and unplugging of the adapter, thereby improving the user experience.

[0132] Compared with doors made entirely of rubber, this type of protective door is made of harder plastic, is less likely to deform, age, or be affected by oil smoke and salt stains. It is more durable and can further extend the service life of the power rail, enhancing the user experience to a certain extent.

[0133] Moreover, since there is only one protective door, a single protective door is used to shield the plug interface. Compared with the solution of using two left and right protective doors, one less protective door is used, which saves the cost of the power rail, simplifies the assembly process of the power rail, and improves the assembly efficiency.

[0134] This embodiment further provides a track socket, which includes a power track and an adapter, wherein the power track is the power track described above, and there are multiple adapters, each of which is pluggable and connected to the power track.

[0135] When the adapter is not inserted into the socket 111 , the protection door of the power rail is in a closed state, and when the adapter is inserted into the socket 111 , the protection door is in an open state, so that the power extraction portion 102 of the adapter 100 extends into the electrode channel 121 .

[0136] In this embodiment, the power rail includes a protective door. When the adapter is not inserted into the plug interface, the protective door shields the plug interface and seals the plug interface. When the adapter is inserted into the plug interface, the adapter applies force to the protective door, pushing the protective door to one side of the plug interface, and the protective door no longer shields the plug interface, so that the adapter contacts the conductive plate in the electrode channel. When the adapter is pulled out of the plug interface, the protective door resets and moves to shield the plug interface. Furthermore, the power rail can improve the safety of the power rail by shielding the plug interface with the protective door, and achieve the effect of waterproofing and dust removal to extend the service life of the power rail.

[0137] Moreover, the material of the protective door is plastic. Compared with a protective door made entirely of metal, the user can insert the adapter into the power rail or unplug the adapter from the power rail with less force, making the plugging and unplugging of the adapter smoother, and there will be no metal friction sound during the plugging and unplugging of the adapter, thereby improving the user experience.

[0138] Compared with doors made entirely of rubber, this type of protective door is made of harder plastic, is less likely to deform, age, or be affected by oil smoke and salt stains. It is more durable and can further extend the service life of the power rail, enhancing the user experience to a certain extent.

[0139] Moreover, since there is only one protective door, a single protective door is used to shield the plug interface. Compared with the solution of using two left and right protective doors, one less protective door is used, which saves the cost of the power rail, simplifies the assembly process of the power rail, and improves the assembly efficiency.

[0140] This embodiment also provides a track socket, which includes a power track and an adapter, wherein the power track is the power track with the first anti-reverse plug-in structure described above, and the adapter is the adapter with the second anti-reverse plug-in structure described above. Specific reference is made to the above description, and no further description is given here.

[0141] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.
