Description

Technical Field

[0001] This invention belongs to the field of electrical connection technology, and more specifically, relates to a waterproof power rail, adapter, and rail socket. Background Technology

[0002] With the increasing prevalence and variety of electrical appliances, the need for power supply is also growing. Fixed power outlets cannot be repositioned to adapt to changing power needs, resulting in poor flexibility. Extension cords offer flexibility in placement, but their large cords take up considerable space and are not aesthetically pleasing. Track sockets consist of a power rail and adapters. The power rail connects to appliances via adapters, which can be installed at different locations on the rail for power supply. The number of adapters can be increased or decreased as needed, facilitating the distribution of power from the rail to different numbers and locations of appliances. However, track sockets using this technology have lower safety standards; the power rail is prone to water and dust accumulation, posing a risk of short circuits. Summary of the Invention

[0003] In view of this, the present invention provides a waterproof power rail, adapter and rail socket to solve the technical problem of how to improve the safety of rail sockets.

[0015] In some embodiments, the electric rail further includes: A first limiting part is disposed within the contact cavity, and the first limiting part protrudes along the width direction; the first limiting part is used to engage the adapter within the contact cavity.

[0016] In some embodiments, the first limiting portion extends along the length direction and is provided with concave and convex shapes in the thickness direction to limit the second limiting portion of the adapter in the width direction.

[0017] In some embodiments, the seat body has a third limiting portion at one end in the width direction; the third limiting portion is used to engage the adapter outside the contact cavity.

[0018] This invention provides an adapter suitable for the aforementioned electric rail, the adapter comprising: ontology; A card holder, at least a portion of which is spaced apart from the body in the thickness direction, and at least a portion of which can be inserted into the contact cavity from the insertion port for electrical connection with the power rail.

[0019] In some embodiments, the body is provided with: The first insertion port is located on the top surface of the main body opposite to the card holder; The second insertion port is located on the side of the main body, and the side is located between the top surface and the card holder in the thickness direction.

[0021] In some embodiments, the second support member has a second limiting part at one end away from the first support member in the width direction. When the second support member is inserted into the power rail, the second limiting part engages with the first limiting part of the power rail. The second limiting part can move relative to the first limiting part between a first position and a second position to realize the switching of power between the adapter and the power rail.

[0022] In some embodiments, at the first position, the second limiting part is partially limited by the first limiting part, and the adapter is electrically connected to the power rail; at the second position, the second limiting part is completely limited by the first limiting part, and the adapter is de-energized from the power rail.

[0025] In some embodiments, the portion of the buckle that protrudes from the body is a fourth limiting portion, which is configured as a groove-shaped structure recessed in the width direction; when the adapter is electrically connected to the power rail, the fourth limiting portion is inserted into the third limiting portion of the power rail.

[0026] This invention provides a track socket, including the aforementioned power track and the aforementioned adapter.

[0027] This invention provides a waterproof power rail, adapter, and rail socket. The rail socket includes a power rail and an adapter, and the adapter is adapted to the power rail. The power rail in this embodiment includes a base and a protective member. The base has a contact cavity extending along its length, and one side of the contact cavity has a through insertion port, allowing the adapter to be inserted into the port in a "side-insertion" manner along its width. When the adapter is inserted into the contact cavity, it can move relative to the contact cavity along its length, thus allowing for compatible placement of the adapter's installation position. The protective member is connected to the base and positioned relative to the insertion port; that is, the protective member partially or completely covers the insertion port, and its orientation is perpendicular to the insertion direction of the port. Compared to the insertion port being located in the thickness direction of the contact cavity, and compared to the "direct insertion" implementation of the adapter, the insertion port in this embodiment is located in the width direction of the contact cavity. This allows the adapter to be inserted through the insertion port in a "side-insertion" manner, thereby making the circuit contact direction of the contact cavity perpendicular to the insertion direction of the insertion port. Furthermore, the protective component blocks external dust or water droplets in the insertion direction of the insertion port, reducing the risk of external dust or water droplets directly entering the contact cavity through the insertion port. This reduces the risk of water and dust accumulation in the contact cavity causing a short circuit, improves the reliability of the circuit connection of the power rail, has higher safety, and facilitates extending the service life of the rail socket.

[0034] This invention provides a track socket. Figure 1 A 3D diagram of the track socket, for reference. Figure 1 Track sockets are used to connect electrical appliances to supply power to them. These appliances can be household appliances such as microwave ovens and ovens, or mobile devices such as mobile phones and computers. It should be noted that the application scenarios of these embodiments do not limit the structure of the track sockets used in these embodiments.

[0035] Reference Figure 1 The track socket includes a power track 1 and an adapter 2. The adapter 2 is equipped with a socket for connecting electrical appliances. The power track 1 supplies power to the appliances through the adapter 2. The power track 1 can be directly installed at the location of the existing wall socket without rewiring or drilling. The length of the power track 1 and the number of adapters 2 can be customized according to user needs. In actual use, the power track 1 can be equipped with indicator lights to improve aesthetics and can replace the baseboard. Figure 2 Here is an exploded view of the track socket, refer to Figure 2 The power rail 1 is detachably connected to the socket. Within the length of the power rail 1, the adapter 2 can be installed at any position on the power rail 1. Furthermore, users can increase or decrease the number of adapters 2 according to actual needs, which provides high flexibility.

[0036] This invention provides a waterproof electric track 1. Figure 3 This is a top view of the track socket. Figure 4 For the track socket in the power-on state Figure 3 Cross-sectional view along the AA direction, refer to Figure 2 and Figure 4 The power rail 1 includes a base 11 and a protective member 12. The base 11 is hollow to form a contact cavity 111, which extends along its length. The contact cavity 111 has a through insertion port 112 on one side in its width direction. It should be noted that "length direction" refers to the direction indicated by arrow N1 in the schematic diagram, and "width direction" refers to the direction indicated by arrow N2 in the schematic diagram. The insertion port 112 is used for inserting an adapter 2. When the adapter 2 is inserted into the contact cavity 111 (e.g....), Figure 1As shown), the adapter 2 can move along the length direction N1 relative to the contact cavity 111 to change the position of the adapter 2 on the power rail 1, so that the adapter 2 can flexibly accommodate the position of electrical appliances.

[0037] In related technical methods, the insertion port is positioned along the thickness direction of the power rail, allowing the adapter to be directly inserted into the contact cavity of the power rail along the thickness direction; this can be understood as "direct insertion." Since old household wall sockets are generally installed sideways on the wall, after the power rail is installed directly at the location of the original wall socket, the power rail remains sideways. Therefore, the insertion port, positioned along the thickness direction of the contact cavity, faces directly towards the external environment, exposing the circuitry within the contact cavity directly to the external environment. In other words, the circuit contact direction of the power rail is consistent with the insertion direction of the insertion port. During long-term use, water droplets or dust can easily enter the contact cavity through the insertion port, potentially causing a short circuit in the power rail's circuitry and affecting user experience.

[0038] In this embodiment, the power rail 1 has the insertion port 112 located on the width direction N2 of the contact cavity 111, allowing the adapter 2 to be inserted into the contact cavity 111 along the width direction N2, which can be understood as "side insertion". Compared with the direct insertion implementation of the adapter 2, the structure of the power rail 1 in this embodiment allows the adapter 2 to be side-inserted. The circuit contact direction of the contact cavity 111 is perpendicular to the insertion direction of the insertion port 112, reducing the risk of water and dust entering the contact cavity 111, lowering the risk of short circuits caused by water and dust accumulation in the contact cavity 111, improving the reliability of the circuit connection of the power rail 1, extending the service life of the power rail 1, and facilitating user use.

[0039] Figure 5 For electric track 1 in Figure 3 Cross-sectional view along the AA direction, refer to Figure 5 The protective component 12 connects to the base 11 and is positioned opposite to the insertion port 112. It should be noted that "insertion port 112" refers to the opening area of ​​the contact cavity 111 that connects to the external environment; the area of ​​"insertion port 112" is approximately... Figure 5 The position enclosed by the dashed rectangular frame, "relatively set," means that, ignoring the area of ​​the region where the insertion port 112 is located and the volume of the protective member 12, the protective member 12 is parallel to the insertion port 112. In other words, the protective member 12 is located at the position where the insertion port 112 is opened on the base 11, and at least partially covers the insertion port 112. It should be noted that the protective member 12 can be as follows: Figure 5The protective member 12 is connected to the inner wall of the base 11 to shield the insertion port 112 within the contact cavity 111; alternatively, the protective member 12 can be connected to the outer wall of the base 11 to shield the insertion port 112 outside the contact cavity 111. It is understood that "within the base 11" means that the outline boundary of the base 11 encloses one side of the contact cavity 111; "outside the base 11" means the side of the base 11 whose boundary outline is exposed to the atmospheric environment. Regardless of which side of the base 11 the protective member 12 is connected to, it is sufficient to ensure that the protective member 12 shields the insertion port 112. The protective member 12 shields the insertion port 112, thereby reducing the risk of dust or water droplets entering the contact cavity 111 from the insertion port 112, and reducing the risk of short circuits within the contact cavity 111.

[0040] It should be noted that the protective member 12 can be made of either a rigid or flexible material. When the protective member 12 is made of a rigid material, it is movably connected to the base 11, for example, the protective member 12 is hinged to the base 11, and the protective member 12 opens the insertion port 112 after the adapter 2 is inserted. When the protective member 12 is made of a flexible material, it can be rotatably connected to the base 11, either with one end fixed to the base 11 or with both ends connected to the base 11. If both ends of the protective member 12 are connected to the base 11, a slit can be provided in the width direction N2 of the protective member 12, through which the adapter 2 passes through the insertion port 112.

[0041] This application provides a waterproof power rail 1, which includes a base 11 and a protective member 12. The base 11 has a contact cavity 111 extending along the length direction N1. The contact cavity 111 has a through insertion port 112 on one side in the width direction N2, allowing an adapter 2 to be inserted sideways through the insertion port 112 along the width direction N2. When the adapter 2 is inserted into the contact cavity 111, the adapter 2 can move relative to the contact cavity 111 along the length direction N1, thus accommodating changes in the installation position of the adapter 2. The protective member 12 is connected to the base 11 and positioned relative to the insertion port 112. That is, when the adapter 2 is not inserted and powered on, the protective member 12 partially or completely covers the insertion port 112. The protective member 12 is positioned perpendicular to the insertion direction of the insertion port 112, thereby preventing dust or water droplets from entering the contact cavity 111 along the insertion direction of the insertion port 112. Compared to the embodiment where the insertion port 112 is located in the thickness direction N3 of the contact cavity 111, allowing the adapter 2 to be "directly inserted," in this embodiment, the insertion port 112 is located in the width direction N2 of the contact cavity 111, allowing the adapter 2 to be "side-inserted" through the insertion port 112. This makes the circuit contact direction of the contact cavity 111 perpendicular to the insertion direction of the insertion port 112. Furthermore, the protective member 12 blocks external dust or water droplets in the insertion direction of the insertion port 112, reducing the risk of external dust or water droplets directly entering the contact cavity 111 through the insertion port 112. This reduces the risk of water and dust accumulation in the contact cavity 111 causing a short circuit, improving the reliability of the circuit connection of the power rail 1, resulting in higher safety and ease of use for users.

[0042] In some embodiments, refer to Figure 5 The protective component 12 is configured as a flexible part, meaning it is capable of elastic deformation. The materials used to make the protective component 12 include, but are not limited to, thermoplastic elastomers, silicone, polypropylene, and rubber. One end of the protective component 12 that connects to the base 11 (the bottom end of the protective component 12 in the schematic diagram) is the connecting end 121, and the other end of the protective component 12 (the top end of the protective component 12 in the schematic diagram) is the free end 122. Figure 5 As shown, the protective member 12 covers the insertion port 112 when it is not subjected to external force. That is, when the protective member 12 is not subjected to external force, the protective member 12 extends along the thickness direction N3 and covers the insertion port 112, thereby achieving waterproof and dustproof protection for the contact cavity 111.

[0043] Figure 6 for Figure 3 The exploded view shows the direction of adapter 2's installation, indicated by the dashed arrow. Refer to the following... Figures 4 to 6 The implementation principle of the protective component 12 is explained as follows: When the adapter 2 is not inserted, the protective component 12 covers the insertion port 112 and extends along the thickness direction N3 (e.g., Figure 5As shown). During the process of inserting the adapter 2 into the contact cavity 111 along the width direction N2, the protective member 12 is subjected to the thrust of the adapter 2 in the width direction N2, and the protective member 12 deforms from extending along the thickness direction N3 to gradually extending along the width direction N2 (as shown). Figure 6 As shown). When adapter 2 is fully inserted into contact cavity 111 (as shown). Figure 4 As shown, the protective member 12 is subjected to pressure from the adapter 2 in the thickness direction N3, causing it to spring upwards in that direction. At this time, the free end 122 of the protective member 12 presses against the adapter 2, resulting in greater friction at the connection between the protective member 12 and the adapter 2, thus improving the connection stability between the adapter 2 and the power rail 1. Furthermore, because the protective member 12 is flexible, the deformation of the portion of the protective member 12 pressed by the adapter 2 differs from that of the portion not pressed by the adapter 2. The deformation of the portion not pressed by the adapter 2 is smaller, thus still able to block the insertion port 112 in the width direction N2. In other words, even when the adapter 2 is not present at the insertion port 112, the protective member 12 can still at least partially block the insertion port 112, reducing the risk of water and dust entering the contact cavity 111 when the adapter 2 is inserted, and improving the reliability of the circuit connection within the contact cavity 111.

[0044] In some embodiments, Figure 7 This is an exploded view of electric track 1, referencing... Figure 5 and Figure 7 The base 11 is provided with a limiting groove 113 extending along the length direction N1. The connecting end 121 of the protective member 12 is disposed in the limiting groove 113. It should be noted that the connecting end 121 can be snapped into the limiting groove 113, or the connecting end 121 can be fixed in the limiting groove 113. The following describes the two embodiments: When the connecting end 121 is engaged with the limiting groove 113, the protective member 12 is detachably connected to the base 11, which facilitates the installation and replacement of the protective member 12. On the other hand, when the connecting end 121 is engaged with the limiting groove 113, the connecting end 121 and the limiting groove 113 are rotatably connected. During the insertion process of the adapter 2, the protective member 12 rotates and generates a small resistance to the adapter 2, which facilitates the insertion of the adapter 2 into the contact cavity 111.

[0045] With the connecting end 121 fixed in the limiting groove 113, the connecting end 121 can be interference-fitted with the limiting groove 113, filling the limiting groove 113 through the deformation of the connecting end 121, thereby limiting the connecting end 121 within the limiting groove 113. Alternatively, the connecting end 121 can be clearance-fitted with the limiting groove 113. After the connecting end 121 is assembled into the limiting groove 113, the connection gap between the connecting end 121 and the limiting groove 113 can be filled with adhesive, thus fixing the connecting end 121 to the limiting groove 113. The connection end 121 being fixed within the limiting groove 113 ensures a stable connection between the protective component 12 and the base 11, effectively reducing the risk of the protective component 12 detaching from the base 11 during repeated deformation.

[0046] Continue to refer to Figure 5 and Figure 7 The limiting groove 113 is disposed within the contact cavity 111, meaning that the protective member 12 is installed within the contact cavity 111, thus preventing dust and dirt from entering the insertion port 112. Compared to embodiments where the protective member 12 is installed outside the contact cavity 111, in some embodiments of this application, the protective member 12 is installed within the contact cavity 111, reducing the contact area between the protective member 12 and the external environment. This reduces the risk of the protective member 12 aging due to complete exposure to the external environment, and helps extend the service life of the protective member 12. It should be noted that the cross-sectional shape of the limiting groove 113 can be an open arc shape as shown in the schematic diagram of this application, or it can be a rectangular or dovetail shape, etc. The limiting groove 113 can be disposed at the bottom of the contact cavity 111 as shown in the schematic diagram of this application, or it can be disposed at the top of the contact cavity 111. Regardless of where the limiting groove 113 is disposed in the contact cavity 111 or what shape the limiting groove 113 is, as long as it can limit the connection end 121, it is acceptable.

[0047] In some embodiments, refer to Figure 5 and Figure 7 The base 11 includes a cover plate 114, a power supply base 115, and a connecting portion 116. The cover plate 114 and the power supply base 115 are spaced apart in the thickness direction N3, meaning that the cover plate 114 and the power supply base 115 have a certain installation gap in the thickness direction N3. The connecting portion 116 connects the cover plate 114 and the power supply base 115 on the same side in the width direction N2. It should be noted that the cover plate 114, the power supply base 115, and the connecting portion 116 can be integrally formed. (Refer to...) Figure 5 To explain, the connecting part 116 is in Figure 5Within the dashed elliptical frame shown, the portion above the connecting part 116 is a cover plate 114, and the portion below the connecting part 116 is a power supply socket 115. The insertion port 112 is located on the side of the cover plate 114 and the power supply socket 115 away from the connecting part 116; that is, the contact cavity 111 is a semi-open structure. The bottom wall of the cover plate 114, the top wall of the power supply socket 115, and the side wall of the connecting part 116 form the contact cavity 111. The power rail 1 also includes three conductive elements 13, which are disposed within the contact cavity 111. The cover plate 114 is disposed in the thickness direction N3, thereby blocking dust or water droplets in the thickness direction N3 to protect the conductive elements 13 and reduce the risk of short circuits.

[0048] It should be noted that, referring to Figure 7 The base 11 has supports 14 at both ends to prevent the adapter 2 from sliding along the length direction N1N2 (e.g., Figure 1 The support body 14 is equipped with a safety switch 141 to control the power supply to and from the power rail 1, thereby achieving overload protection for the power rail 1.

[0049] In some embodiments, refer to Figure 5 When the protective member 12 is not subjected to external force, the dimension of the protective member 12 in the thickness direction N3 is smaller than the minimum distance between the connecting end 121 and the conductive member 13. The protective member 12 in... Figure 5 The state shown is the state without external force. The thickness N3 dimension of the protective component 12 in the state without external force is... Figure 5 The height of the protective element 12. "Minimum distance from connection end 121 to conductive element 13" refers to the minimum distance of the line segment connecting the midpoint of connection end 121 and the endpoint of conductive element 13. Figure 5 In the state shown, the height of the protective member 12 is less than the minimum distance between the connecting end 121 and the conductive member 13. That is to say, even if the protective member 12 undergoes maximum deformation after the adapter 2 is inserted (e.g. Figure 4 There is still a gap between the free end 122 of the protective element 12 and the conductive element 13. The protective element 12 will not cover the conductive element 13. That is to say, the effective conductive area of ​​the conductive element 13 is not affected by the protective element 12, which facilitates the electrical connection between the conductive element 13 and the adapter 2.

[0050] In some embodiments, refer to Figure 5The conductive component 13 has a snap-fit ​​portion 131 and a protrusion 132. The snap-fit ​​portion 131 is snapped into the power rail 1 to achieve assembly of the conductive component 13. The conductive component 13 and the power rail 1 are detachably connected, facilitating the installation and subsequent maintenance of the conductive component 13. Two snap-fit ​​portions 131 are provided, and the protrusion 132 is located between the two snap-fit ​​portions 131 in the width direction N2; that is, the portions on both sides of the protrusion 132 are snap-fit ​​portions 131. The two snap-fit ​​portions 131 together fix the conductive component 13, and the conductive component 13 is evenly stressed at both ends in the width direction N2, improving the installation stability of the conductive component 13 and the power rail 1. The protrusion 132 protrudes relative to the snap-fit ​​portion 131, and the protrusion 132 is located between the two snap-fit ​​portions 131 in the width direction N2; that is, the cross-section of the conductive component 13 is convex. Figure 5 To explain, Figure 5 The portion within the circular dashed frame shown is the snap-fit ​​portion 131, and the protruding portion located between the two circular dashed frames is the protrusion portion 132. In the thickness direction N3, there is a gap between the protrusion portion 132 and the snap-fit ​​portion 131, which is used to allow the conductive component 13 to deform.

[0051] The side of the protrusion 132 opposite to the engaging portion 131 is defined as the first end face 1321. That is, the first end face 1321 is located on the side of the protrusion 132 away from the engaging portion 131, and, neglecting thickness, it is parallel to the engaging portion 131. (Refer to...) Figure 4 The first end face 1321 is used for electrical connection with the adapter 2. On the one hand, the area of ​​the first end face 1321 is larger than that of the other end faces of the conductive element 13. The first end face 1321 provides contact connection for the adapter 2, which facilitates a reliable connection between the adapter 2 and the conductive element 13. On the other hand, the first end face 1321 is in contact with the plane of the adapter 2, which makes it easy for the adapter 2 to press against the first end face 1321. This causes the conductive element 13 to deform under pressure. The conductive element 13 rebounds and presses against the contact pin 223 of the adapter 2. The adapter 2 and the conductive element 13 are stably abutted, which makes the adapter 2 and the power rail 1 stably fixed, improving the circuit connection stability of the rail socket under the power-on state.

[0052] In some embodiments, refer to Figure 5The conductive element 13 includes a first conductive element 133, a second conductive element 134, and a third conductive element 135. The first conductive element 133 is used to connect to the live wire to provide power supply voltage; the second conductive element 134 is used to connect to the neutral wire to return voltage to the power supply; and the third conductive element 135 is used to connect to the ground wire to achieve electric shock protection for the power rail 1. The first conductive element 133 and the second conductive element 134 are disposed on the power supply base 115, and are located on the same component to facilitate the formation of a power circuit between the live wire and the neutral wire. The third conductive element 135 is disposed on the cover plate 114, and is spaced apart from the first conductive element 133 in the thickness direction N3. Compared with the embodiment where all three conductive elements 13 are disposed on the same plane along the width direction N2, in some embodiments of this application, the third conductive element 135 is disposed on different planes, reducing the volume of the contact cavity 111 in the width direction N2, thereby reducing the footprint of the power rail 1 and facilitating user operation.

[0053] On the other hand, refer to Figure 4 When the adapter 2 is inserted and connected to power, both ends of the power-connecting part of the adapter 2 are subjected to the rebound force of the conductive member 13 in the thickness direction N3. The three conductive members 13 press against the power-connecting part of the adapter 2 in both directions in the thickness direction N3, so that the power-connecting part of the adapter 2 is stably clamped in the contact cavity 111, which improves the installation stability of the adapter 2 and the circuit connection stability between the adapter 2 and the power rail 1.

[0054] In some embodiments, refer to Figure 5 and Figure 7 The power supply socket 115 is provided with a first slot 1151 and a second slot 1152, which are located on the side of the power supply socket 115 near the contact cavity 111 (i.e. Figure 5 At the top of the power supply socket 115, the first slot 1151 and the second slot 1152 are arranged side by side in the width direction N2. The first conductive element 133 is disposed in the first slot 1151, and the second conductive element 134 is disposed in the second slot 1152. The first slot 1151 and the second slot 1152 provide mounting references for the first conductive element 133 and the second conductive element 134, facilitating their installation. The first slot 1151 correspondingly limits the first conductive element 133, and the second slot 1152 correspondingly limits the second conductive element 134, thereby restricting the freedom of the first conductive element 133 and the second conductive element 134 within the contact cavity 111, ensuring a reliable connection between the two conductive elements 13 and the adapter 2. On the other hand, the first slot 1151 and the second slot 1152 are arranged side by side to separate the first conductive element 133 and the second conductive element 134, so as to reduce the risk of the first conductive element 133 and the second conductive element 134 coming into contact, thereby reducing the risk of short circuit of the power rail 1 due to the connection of the live wire and the neutral wire.

[0055] In some embodiments, refer to Figure 5 and Figure 7 A third slot 1153 is provided on the side of the cover plate 114 near the contact cavity 111, that is, the third slot 1153 is located at the bottom of the cover plate 114. A third conductive element 135 is disposed in the third slot 1153, and the third slot 1153 limits the third conductive element 135 to reduce the risk of the third conductive element 135 contacting other conductive elements 13, reduce the risk of short circuit in the ground wire causing the base 11 to become electrified, and effectively prevent electric shock. It should be noted that the description of the embodiment with the third slot 1153 here tends to emphasize the differences between it and the various embodiments above. The similarities or similarities can be referred to each other. For the sake of brevity, they will not be repeated here.

[0056] Reference Figure 5 Since the positions of the first slot 1151 and the second slot 1152 are similar, only the first slot 1151 will be described here.

[0057] In related technical means, the third slot and the first slot can be positioned on the same straight line in the thickness direction, so that the third conductive element and the first conductive element are positioned opposite each other in the thickness direction. Defined as P1, in this embodiment, the thickness spaces of the third conductive element and the first conductive element overlap on the same vertical line, which easily increases the volume of the contact cavity in the thickness direction, thereby increasing the volume of the power rail in the thickness direction. This is not conducive to the fit between the power rail and the mounting wall, affecting the user experience.

[0058] In related technical methods, the first slot can also be positioned between the third slot and the second slot in the width direction. This embodiment is defined as P2. In P2, the third conductive element is located outside the gap between the first and second conductive elements in the width direction. The maximum gap between the three conductive elements in the width direction is equal to the gap between the third and first conductive elements in the width direction plus the gap between the first and second conductive elements in the width direction. This easily increases the volume of the contact cavity in the width direction, thereby increasing the footprint of the power rail and making it difficult for users to assemble the power rail.

[0059] In some embodiments of this application, reference is made to Figure 5In the width direction N2, the third slot 1153 is located between the first slot 1151 and the second slot 1152. Compared with the implementation in P1, in this embodiment, the thickness spaces of the first conductive element 133 and the second conductive element 134 are staggered with the thickness space of the third conductive element 135, reducing the volume of the contact cavity 111 in the thickness direction N3. Compared with the implementation in P2, in this embodiment, the maximum spacing between the three conductive elements 13 in the width direction N2 is only the spacing between the first conductive element 133 and the second conductive element 134 in the width direction N2, reducing the volume of the contact cavity 111 in the width direction N2. In summary, the three slots in this embodiment are compactly arranged, allowing the three conductive elements 13 to fully utilize the volume within the contact cavity 111, resulting in high space utilization. Furthermore, the width and thickness of the power rail 1 are more balanced, facilitating user installation.

[0060] In some embodiments, refer to Figure 5 and Figure 7 The power rail 1 also includes an insulating element 15. The insulating element 15 can be disposed in the first slot 1151 to isolate the power supply base 115 and the first conductive element 133; the insulating element 15 can be disposed in the second slot 1152 to isolate the power supply base 115 and the second conductive element 134; and the insulating element 15 can also be disposed in the third slot 1153 to isolate the cover plate 114 and the third conductive element 135. It should be noted that, in addition to the above-described embodiments, the insulating element 15 can also be disposed in the first slot 1151 and the second slot 1152, or the first slot 1151 and the third slot 1153, or the second slot 1152 and the third slot 1153, or even in all three slots. The number of insulating elements 15 is related to the distance between the three conductive elements 13. If the distance between the three conductive elements 13 is insufficient to generate a magnetic field effect, the number of insulating elements 15 can be reduced accordingly.

[0061] In the embodiments illustrated in the schematic diagrams of this application, reference is made to... Figure 5 Each of the three slots is equipped with an insulating element 15, so that the three conductive elements 13 are insulated from the base 11, thereby protecting the power rail 1 in a small volume and reducing the risk of the base 11 becoming energized and accidentally injuring the user.

[0062] In some embodiments, refer to Figure 6The power rail 1 also includes a first limiting part 117, which is disposed within the contact cavity 111 and protrudes along the width direction N2. The adapter 2 is inserted into the contact cavity 111 along the width direction N2. Therefore, the first limiting part 117 is connected to the inner side of the connecting part 116. The first limiting part 117 is used to engage with the adapter 2. When the adapter 2 is inserted into the contact cavity 111, the portion of the adapter 2 within the contact cavity 111 engages with the first limiting part 117. The portion of the adapter 2 inserted into the contact cavity 111 can be a retainer 22. (Refer to...) Figure 4 The first limiting portion 117 extends along the width direction N2, thereby limiting the card holder 22 to a specific position in the thickness direction N3 of the contact cavity 111. When the track socket is energized, the card holder 22 maintains stable contact with the three conductive elements 13 in the thickness direction N3, reducing the risk of the card holder 22 sliding along the thickness direction N3 and separating from some of the conductive elements 13 under gravity. The first limiting portion 117 ensures stable contact between the card holder 22 and the three conductive elements 13 when energized, improving the reliability of the electrical connection between the adapter 2 and the power track 1. Furthermore, the first limiting portion 117 extends along the width direction N2, and the insertion direction of the adapter 2 is also in the width direction N2. The extension direction of the first limiting portion 117 coincides with the insertion direction of the adapter 2, facilitating the insertion of the adapter 2 into the contact cavity 111.

[0063] It should be noted that the first limiting part 117 can be a protrusion integrally formed inside the connecting part 116, or the first limiting part 117 can be a component provided inside the connecting part 116. For example, the first limiting part 117 can be a positive magnet. Correspondingly, a negative magnet can be provided in the part where the adapter 2 is inserted into the contact cavity 111. The positive and negative magnets attract each other, thereby limiting the adapter 2 in the contact cavity 111.

[0064] In some embodiments, refer to Figure 4 The first limiting portion 117 extends along the length direction N1, meaning that the adapter 2 can engage with the first limiting portion 117 at any position along the length direction N1 of the contact cavity 111, improving the efficiency for the user to change the position of the adapter 2. The first limiting portion 117 is recessed and convex in the thickness direction N3, that is, it is divided into multiple parts along the width direction N2, with thickness differences between these parts. With the first limiting portion 117 recessed and convex in the thickness direction N3, when the card holder 22 engages with the recessed part of the first limiting portion 117, the card holder 22 is blocked in the width direction N2 by the protrusion 132 of the first limiting portion 117, thus stably limiting the card holder 22 to the first limiting portion 117 in the width direction N2 (e.g., ...). Figure 4 This improves the positional stability of adapter 2 when it is powered on, thereby improving the reliability of the power connection of the track socket.

[0065] It should be noted that the first limiting part 117 extends along the length direction N1. Therefore, when the connecting friction between the first limiting part 117 and the adapter 2 is small, the adapter 2 can slide along the length direction N1 on the first limiting part 117 to adjust the relative position of the adapter 2 and the power rail 1 in the length direction N1. The first limiting part 117 supports the adapter 2 in the length direction N1, so that the adapter 2 can slide stably in the length direction N1, making it convenient for the user to change the position of the adapter 2 in the length direction N1.

[0066] In some embodiments, refer to Figure 4 and Figure 6 The base 11 has a third limiting part 1181 at one end in the width direction N2, that is, the third limiting part 1181 is located outside the contact cavity 111. The third limiting part 1181 is used to engage the adapter 2 outside the contact cavity 111. As can be seen from the above, the first limiting part 117 engages the adapter 2 inside the contact cavity 111, so that the adapter 2 is stably connected to the power rail 1 both inside and outside the contact cavity 111. The installation stability of the adapter 2 and the power rail 1 is high, reducing the risk of the adapter 2 detaching from the power rail 1 due to accidental contact by external force or vibration.

[0067] It should be noted that the third limiting part 1181 can be a protrusion or groove integrally formed on the side of the base 11, or it can be a component that is separately formed and then assembled on the side of the base 11, such as a magnet. Regardless of the structure of the third limiting part 1181, it is acceptable as long as the third limiting part 1181 can be snapped onto the adapter 2 outside the contact cavity 111.

[0068] This application provides an adapter 2 for use with the power rail 1 in any of the above embodiments, referring to... Figure 2 The adapter 2 includes a body 21 and a socket 22. The socket 22 is at least partially spaced from the body 21 in the thickness direction N3, that is, a certain gap space is formed between the socket 22 and the body 21. The thickness of this gap space is related to the thickness of the cover plate 114, so that the adapter 2 avoids the cover plate 114 when it is assembled into the contact cavity 111. Part of the socket 22 can be inserted into the contact cavity 111 through the insertion port 112 to electrically connect with the power rail 1, thereby realizing the power supply path from the power rail 1 to the adapter 2. When the adapter 2 is inserted into the contact cavity 111 (e.g. Figure 4 As shown, part of the card holder 22 is disposed in the contact cavity 111 and can be electrically connected to the conductive element 13. The cover supports the body 21 to realize the assembly of the adapter 2 and the power rail 1.

[0069] In some embodiments, refer to Figure 1 and Figure 2The main body 21 has a first socket 211 and a second socket 212. The first socket 211 is located on the top surface of the main body 21 opposite to the card holder 22. It should be noted that "opposite" means that, ignoring the thickness, the top surface of the main body 21 is parallel to the extension plane of the card holder 22, and the thickness space of the main body 21 is between the top surface and the extension plane of the card holder 22. The second socket 212 is located on the side of the main body 21, which is located between the top surface and the card holder 22 in the thickness direction N3. That is to say, "the side of the main body 21" refers to the surface that encloses the thickness space of the main body 21. The types of the first socket 211 and the second socket 212 include, but are not limited to, Type-A, Type-B, Type-C, miniUSB, microUSB, two-hole socket, three-hole socket, and five-hole socket. Users can set the types of the first socket 211 and the second socket 212 according to their actual needs.

[0070] In the embodiments illustrated in the schematic diagram of this application, the first socket 211 is configured as a five-hole socket, and the second socket 212 is configured as a two-hole socket, with the second socket 212 opening along the width direction N2. Compared to the implementation where the second socket 212 is located in the length direction N1, in some embodiments of this application, the second socket 212 is located in the width direction N2, so that the position of the appliance plug is not in the shifting direction of the adapter 2. That is, the appliance plug will not interfere with the sliding of the adapter 2 in the length direction N1 of the power rail 1, which facilitates the flexibility of the adapter 2 in changing its position. On the other hand, when the power rail 1 is equipped with a sufficient number of adapters 2, the operating space for connecting appliances in the length direction N1 of adjacent adapters 2 is small. However, the operating space of the adapter 2 in the width direction N2 is not limited by the number of adapters 2 assembled. Therefore, the second socket 212 is located in the width direction N2, which facilitates the connection of the appliance plug and the sliding of the adapter 2 in the length direction N1.

[0071] In some embodiments, Figure 8 Here is an exploded view of adapter 2, refer to Figure 6 and Figure 8 The card holder 22 includes a first support member 221 and a second support member 222. The second support member 222 is spaced from the body 21 in the thickness direction N3, that is, the second support member 222 extends along the width direction N2. One end of the first support member 221 is connected to one end of the body 21 in the width direction N2, and the other end of the first support member 221 is connected to the second support member 222. Therefore, the first support member 221 extends along the thickness direction N3. It should be noted that the first support member 221 and the second support member 222 can be integrally formed. The second support member 222 has one side in the thickness direction N3 (… Figure 8 The bottom side of the second support member 222 in the schematic diagram is provided with a live wire contact 2231 and a neutral wire contact 2232. On the other side of the second support member 222 in the thickness direction N3 ( Figure 8 The top side of the second support member 222 in the schematic diagram is provided with a ground contact 2233. When the adapter 2 is electrically connected to the power rail 1, the live contact 2231 contacts the first conductive member 133, the neutral contact 2232 contacts the second conductive member 134, and the ground contact 2233 contacts the third conductive member 135. The adapter 2 and the power rail 1 form an electrical path, thereby distributing the electrical energy of the power rail 1 to the electrical appliances connected to the adapter 2.

[0072] In some embodiments, refer to Figure 6 The track socket includes a power track 1 and an adapter 2. The power track 1 has a contact cavity 111 extending along its length direction N1. One end of the contact cavity 111 in the width direction N2 has a through insertion port 112, meaning the insertion direction of the insertion port 112 is in the width direction N2. The adapter 2 can be at least partially "side-inserted" into the contact cavity 111 through the insertion port 112. The portion of the adapter 2 that can be inserted into the contact cavity 111 through the insertion port 112 can be the aforementioned second support member 222. The implementation principle of the adapter 2 "side-inserting" into the contact cavity 111 is as described above and will not be repeated here.

[0073] In related technical means, a safety switch on the power rail can be used to control the power supply between the adapter and the power rail. When the adapter is electrically connected to the power rail and no appliance is plugged into it, the power supply circuit within the rail socket still operates, and current continues to flow through the adapter. This means the adapter is "unloaded" but still experiences power loss, which is not energy-efficient and can easily cause it to overheat and become flammable under prolonged current flow, posing a safety hazard. However, the safety switch on the power rail controls the power supply to the entire rail socket. When using the safety switch to reduce the adapter's no-load power loss, other adapters connected to appliances and in operation will be de-energized, affecting user experience. Furthermore, during the process of the adapter being electrically connected to the power rail and changing position along its length, the adapter's energized slippage can easily cause arcing, which can lead to accidental contact with the user, affecting the user's ability to change the adapter's position along the length and creating a safety hazard.

[0074] In the embodiments of this application, Figure 9 For the track socket in the power off state Figure 3 Cross-sectional view along the AA direction, refer to Figure 4 and Figure 9 With adapter 2 plugged into power rail 1, the portion of adapter 2 inserted into contact cavity 111 can move relative to power rail 1 between a first position and a second position, wherein... Figure 4 This is a schematic diagram of adapter 2 in the first position, where power rail 1 is electrically connected to adapter 2; Figure 9This diagram illustrates adapter 2 in its second position, where the power rail 1 and adapter 2 are de-energized. In other words, the power supply to and from the power rail 1 is switched by moving adapter 2 relative to the power rail 1 between the first and second positions. This simple structure facilitates implementation. By individually switching each adapter 2 between the first and second positions, the user can independently control the power supply to and from each adapter 2 and the power rail 1. This allows the user to easily adjust the relative position of adapter 2 and the power rail 1 along the length direction N1, reducing the power consumption of adapter 2 under no-load conditions and improving the safety of the power rail 1.

[0075] In related technical methods, the adapter can be equipped with a rotating telescopic structure. The adapter rotates at a certain angle along the central axis in the insertion direction of the insertion port, causing the rotating telescopic structure to extend or retract, thereby realizing the connection and disconnection of power between the adapter and the power rail. In this implementation, the relative position of the adapter and the power rail remains unchanged, and the rotating telescopic structure of the adapter extends or retracts as the adapter rotates. When the rotating telescopic structure is retracted, the adapter is easily loosened by accidental contact from external forces or vibration, affecting user operation.

[0076] In this embodiment, the adapter 2 can move relative to the power rail 1 between a first position and a second position. That is, there is a relative positional change between the adapter 2 and the power rail 1. Therefore, the adapter 2 translates rather than rotates within the contact cavity 111. The adapter 2 switches between the first and second positions while plugged into the power rail 1. In other words, the adapter 2 remains plugged into the contact cavity 111 during both power-on and power-off states. Even when the adapter 2 is in the second position and the power is off, it is still partially plugged into the contact cavity 111. Compared to related technologies that use rotation, extension, and power-on / off switching, the adapter 2 in this embodiment remains confined within the contact cavity 111 even when the power is off, preventing it from detaching from the insertion port 112 and reducing the risk of damage due to detachment. This extends the lifespan of the adapter 2 and improves user convenience.

[0077] In some embodiments, refer to Figure 4 and Figure 9The first and second positions are two locations of the track socket in the width direction N2. That is, when adapter 2 is plugged into the contact cavity 111, switching between the first and second positions along the width direction N2 of adapter 2 enables power connection / disconnection between adapter 2 and the power track 1. The insertion direction of the insertion port 112 is also in the width direction N2, so the movement direction of adapter 2 during power-on / disconnection is consistent with the insertion direction of insertion port 112. The user does not need to rotate adapter 2 within the contact cavity 111, nor does the user need to move adapter 2 along the thickness direction N3 within the contact cavity 111. External force from the user only needs to be applied to adapter 2 in the width direction N2 of the contact cavity 111 to simultaneously achieve the installation and power-on (or power-off) of adapter 2, facilitating user operation. Utilizing the width space of the contact cavity 111 allows for the installation of adapter 2 and its translation between the first and second positions, resulting in high space utilization. This helps reduce the volume of the contact cavity 111 in the thickness direction N3, thereby reducing the volume of the power track 1 and facilitating the installation of the track socket.

[0078] In some embodiments, refer to Figure 6 The power rail 1 is provided with a first limiting part 117, which is disposed within the contact cavity 111. The adapter 2 is provided with a second limiting part 224. When the adapter 2 is inserted into the contact cavity 111, the first limiting part 117 and the second limiting part 224 engage. It should be noted that the first limiting part 117 can be a protruding structure disposed within the contact cavity 111, and correspondingly, the second limiting part 224 can be a groove structure. If the wall thickness of the power rail 1 is sufficient, the first limiting part 117 can also be a groove structure recessed into the cavity wall of the contact cavity 111, and correspondingly, the second limiting part 224 can be a protruding structure.

[0079] In the above embodiment, the first limiting part 117 can be fixedly connected to the adapter 2 and is only used to limit the adapter 2 within the contact cavity 111. In this embodiment, the second limiting part 224 can move relative to the first limiting part 117 between a first position and a second position; that is, the second limiting part 224 can slide along the first limiting part 117 in the width direction N2. The first limiting part 117 provides a support position for the second limiting part 224, reducing the risk of the adapter 2 tilting in the thickness direction N3 during power-on / off processes, improving the sliding stability of the second limiting part 224 in the width direction N2, facilitating stable sliding of the second limiting part 224 between the first and second positions, and improving the accuracy of controlling the power-on / off switching of the adapter 2.

[0080] In some embodiments, refer to Figure 6The first limiting part 117 is a protruding structure extending along the width direction N2, and correspondingly, the second limiting part 224 is a groove structure. It should be noted that the first limiting part 117 can be integrally formed as a part inside the power rail 1, as shown in the schematic diagram of this application, or it can be a separately formed component assembled into the contact cavity 111. The protruding structure of the first limiting part 117 reduces the wall thickness of the contact cavity 111, thereby reducing the volume and weight of the power rail 1, facilitating stable installation of the power rail 1 on the wall, and reducing the risk of the power rail 1 falling off due to its large weight after installation. Simultaneously, the groove structure of the second limiting part 224 reduces the volume of the second support member 222, thereby reducing the weight of the adapter 2, reducing the risk of the adapter 2 loosening due to excessive weight, and improving the user experience.

[0081] In some embodiments, Figure 10 for Figure 4 Enlarged view of section B, see reference. Figure 10 The inner side of the second limiting portion 224 is provided with a second protrusion 2241, which is the portion protruding from the inner side of the second limiting groove 113. It should be noted that "inner side of the second limiting portion 224" refers to the side of the outline boundary of the second limiting portion 224 that is closer to the first limiting portion 117 in the thickness direction N3. The outer side of the first limiting portion 117 is provided with a first groove 1171, and "outer side of the first limiting portion 117" refers to the side of the boundary outline of the first limiting portion 117 that is closer to the second limiting portion 224 in the thickness direction N3. Multiple first grooves 1171 are spaced apart in the width direction N2, combined with... Figure 10 To explain, the recessed portion of the first limiting part 117 in the thickness direction N3 is a first groove 1171. The setting of the first groove 1171 increases the friction coefficient on the outer side of the first limiting part 117, and the setting of the second protrusion 2241 increases the friction coefficient on the inner side of the second limiting part 224, thereby increasing the connecting friction between the first limiting part 117 and the second limiting part 224, facilitating a stable connection between the first limiting part 117 and the second limiting part 224, and reducing the risk of the second limiting part 224 separating from the first limiting part 117 during the power-on and power-off process of the adapter 2, thus preventing the adapter 2 from detaching from the insertion port 112.

[0082] Figure 11 for Figure 9 Enlarged view of section C, see reference. Figure 10 and Figure 11During the transition from the first position to the second position, the second protrusion 2241 is limited and connected to different first grooves 1171. That is, regardless of whether the second limiting part 224 is in the first position or the second position, the first limiting part 117 can limit the second protrusion 2241 through the first groove 1171, so that the first limiting part 117 can be engaged by the first groove 1171 in both the first and second positions, which improves the installation stability of the adapter 2 in different positions, thereby reducing the risk of the adapter 2 falling off the power rail 1 in the power-on and power-off states.

[0083] It should be noted that the second protrusion 2241 can be provided in one or multiple ways. Regardless of how many second protrusions 2241 are provided, as long as the second protrusion 2241 can be engaged with different first grooves 1171 during the movement of the second limiting part 224 in the width direction N2.

[0084] The following, combined with Figure 10 and Figure 11 The implementation principle of the first groove 1171 and the second protrusion 2241 is explained as follows: exist Figure 10 and Figure 11 In the middle, the second protrusion 2241 is provided in two sets, each set having two second protrusions 2241 facing away from each other in the thickness direction N3, that is, there are four second protrusions 2241. The positions of the two sets of second protrusions 2241 correspond to the first position and the second position of the adapter 2, respectively, and the first groove 1171 is provided in two sets corresponding to the second protrusions 2241. (Refer to...) Figure 10 At the first position, the rightmost set of first protrusions 132 engages with the leftmost set of first grooves 1171; see reference. Figure 11 At the second position, two sets of second protrusions 2241 are correspondingly engaged with two sets of first grooves 1171. The two sets of first grooves 1171 together limit the second limiting part 224, thereby improving the relative positional stability of the adapter 2 in the width direction N2 of the power rail 1 when the power is off. The width direction N2 is the insertion and removal direction of the adapter 2. The first grooves 1171 limit the adapter 2 in the insertion and removal direction of the adapter 2, so that the adapter 2 will not detach from the power rail 1 when the power is on or off, reducing the risk of the adapter 2 detaching from the power rail 1 and being subjected to impact or drop, and improving the service life of the adapter 2.

[0085] In some embodiments, refer to Figure 9 and Figure 11At the second position, adapter 2 partially abuts against the power rail 1 in the width direction N2. When the user slides adapter 2 in the width direction N2, a significant blocking force is applied, preventing adapter 2 from moving further in the width direction N2. This can be understood as adapter 2 being "fully inserted." It should be noted that at the second position, the first support member 221 of adapter 2 may abut against the insertion port 112 of the power rail 1, or the second support member 222 of adapter 2 may abut against the inner side of the connecting part 116 (e.g., ...). Figure 9 As shown in the diagram, the first limiting part 117 and the second limiting part 224 can also abut at their ends in the width direction N2. In the second position, regardless of which part of the adapter 2 abuts against the power rail 1, the adapter 2 is blocked in the width direction N2, and the adapter 2 is "fully inserted" in the contact cavity 111. The user experiences greater resistance in the width direction N2, allowing the user to intuitively see that the adapter 2 has slid to the second position, making it easy for the user to intuitively judge whether the adapter 2 is de-energized.

[0086] In some embodiments, refer to Figure 4 The track socket includes a power track 1, an adapter 2, and a first limiting mechanism 3. The adapter 2 can be inserted into the power track 1 from the side, that is, the adapter 2 is "side-inserted" into the power track 1 along the width direction N2. The adapter 2 can be "side-inserted" into the contact cavity 111 of the power track 1 from the insertion port 112 mentioned above. After the adapter 2 is inserted into the power track 1, an electrical connection between the adapter 2 and the power track 1 is achieved to form a power supply circuit for the track socket to supply power to the electrical appliance.

[0087] In related technologies, a rotating telescopic structure can be used to switch the adapter on and off from the power rail. As mentioned above, when the adapter is electrically connected to the power rail, the rotating telescopic structure extends from the contact cavity, thus locking the adapter into the power rail. However, the rotating telescopic structure needs to retract to disconnect the adapter from the power rail. When the rotating telescopic mechanism is retracted, the adapter is prone to detaching from the power rail at the insertion point. After detaching from the power rail, the adapter is susceptible to impacts or drops, which affects its lifespan and is detrimental to user experience.

[0088] In this embodiment, the first limiting mechanism 3 is used to engage with the power rail 1. The insertion direction of the power rail 1 is in the width direction N2, meaning that at least one side of the power rail 1 in the width direction N2 can abut against the first limiting mechanism 3 to achieve engagement between the first limiting mechanism 3 and the power rail 1. The first limiting mechanism 3 is movably connected to the adapter 2, meaning that the first limiting mechanism 3 can move synchronously with the adapter 2, and the first limiting mechanism 3 can also move relative to the power rail 1. It should be noted that the movable connection method between the first limiting mechanism 3 and the adapter 2 is not limited in this embodiment. For example, the first limiting mechanism 3 can translate and / or rotate relative to the adapter 2. Regardless of the connection method used, as long as engagement between the first limiting mechanism 3 and the power rail 1 can be achieved, it is acceptable.

[0089] Adapter 2 is inserted into the power rail 1 from the side. Therefore, the degree of freedom of adapter 2 in inserting into the power rail 1 is in the width direction N2. Since adapter 2 can only achieve electrical connection with the power rail 1 by being inserted from the side, the degree of freedom of adapter 2 in switching on and off within the power rail 1 is also in the width direction N2. The first limiting mechanism 3 is used to engage with the power rail 1. Therefore, at least one side of the first limiting mechanism 3 can abut against the power rail 1 in the width direction N2 to limit the portion of adapter 2 electrically connected to the power rail 1 within the contact cavity 111. When adapter 2 attempts to detach from the insertion port 112 along the width direction N2, that is, when the adapter 2 is disconnected from the power rail 1, the first limiting mechanism 3 can engage the power rail 1, thereby reducing the risk of adapter 2 detaching from the insertion port 112. Therefore, even when adapter 2 is disconnected from the power rail 1 within the contact cavity 111, the first limiting mechanism 3 can still block adapter 2, ensuring that adapter 2 remains plugged into the contact cavity 111 even when the circuit is open. This reduces the risk of adapter 2 detaching from the power rail 1 when the power is off, improving the user experience. On the other hand, the first limiting mechanism 3 can engage with the power rail 1. When the friction at the engagement point between the first limiting mechanism 3 and the power rail 1 is high, adapter 2 can be fixed at a certain position along the length N1 of the power rail 1, reducing the risk of adapter 2 moving due to accidental contact or vibration from external forces. This reduces the risk of adapter 2 separating from the electrical plug and improves the stability of the connection between adapter 2 and the electrical appliance.

[0090] In some embodiments, Figure 12 This is a schematic diagram of the first limiting mechanism 3 retracting the adapter 2, refer to... Figure 4 and Figure 12The first limiting mechanism 3 is movably connected to the adapter 2 in the thickness direction N3, meaning the first limiting mechanism 3 translates relative to the adapter 2. During the process of installing the adapter 2 onto the power rail 1, the adapter 2 retracts into the adapter 2 in the thickness direction N3, so that the first limiting mechanism 3 avoids the insertion action of the adapter 2 from the insertion port 112 into the contact cavity 111 in the width direction N2. After the adapter 2 is installed on the power rail 1, that is, after the adapter 2 is inserted from the insertion port 112 into the contact cavity 111, the first limiting mechanism 3 protrudes from the adapter 2 in the thickness direction N3. In other words, during the process of inserting the adapter 2 from the insertion port 112 and intending to electrically connect it to the power rail 1, the adapter 2 only moves in the width direction N2, and the first limiting mechanism 3 protrudes in the thickness direction N3, having a locking direction for engaging the power rail 1. For ease of explanation, the state of "electrical connection between adapter 2 and power rail 1" is defined as "adapter 2 in position". The insertion direction of adapter 2 is consistent with the locking direction of the first limiting mechanism 3. The first limiting mechanism 3 can lock the power rail 1 to realize the insertion of adapter 2 and power rail 1, forming the power supply circuit of the rail socket.

[0091] In some embodiments, refer to Figure 6 and Figure 10 The power rail 1 has a third limiting portion 1181 protruding in the width direction N2. That is, the third limiting portion 1181 is connected to the side of the power rail 1 and extends along the width direction N2. When the adapter 2 is electrically connected to the power rail 1, the first limiting mechanism 3 engages with the outside of the third limiting portion 1181. It should be noted that "outside of the third limiting portion 1181" means the side of the boundary contour of the third limiting portion 1181 that is away from the contact cavity 111. The first limiting mechanism 3 engages with the outside of the third limiting portion 1181, so that the first limiting structure abuts against the third limiting portion 1181 in both the thickness direction N3 and the width direction N2. The first limiting mechanism 3 abuts against the third limiting portion 1181 in the width direction N2 to provide a reference for the adapter 2 to be inserted into position. The user can visually determine whether the adapter 2 is electrically connected to the power rail 1 through the obstruction of the first limiting mechanism 3, facilitating the user's operation of the electrical connection of the adapter 2 to the power rail 1.

[0092] When the adapter 2 is disconnected from the power rail 1, the first limiting mechanism 3 is positioned on one side of the width direction N2, spaced apart from the third limiting part 1181. That is, when the adapter 2 is disconnected, the first limiting mechanism 3 and the third limiting part 1181 are spaced apart in the width direction N2 (e.g., ...). Figure 11 (As shown). The following, in conjunction with... Figure 9 The principle by which adapter 2 is limited to the contact cavity 111 when the circuit is open is explained: In the event of a disconnection between adapter 2 and power rail 1, power rail 1 is positioned between the first support member 221 and the first limiting mechanism 3 in the width direction N2. If adapter 2 slides to the left along the width direction N2 and attempts to detach from power rail 1, the first limiting mechanism 3 can abut against the third limiting part 1181, thereby preventing adapter 2 from sliding to the left and reducing the risk of adapter 2 sliding to the left and detaching from the insertion port 112.

[0093] On the other hand, the first limiting mechanism 3 abuts against the third limiting part 1181 in the thickness direction N3, and the portion of the adapter 2 outside the contact cavity 111 abuts against the top surface of the power rail 1 in the thickness direction N3. That is, the body 21 abuts against the cover plate 114 in the thickness direction N3, and the first limiting mechanism 3 extends out of the adapter 2 and abuts against the third limiting part 1181 in the thickness direction N3. When the friction between the third limiting part 1181 and the first limiting mechanism 3 is sufficient, the power rail 1 can be pressed tightly between the first limiting mechanism 3 and the body 21 in the thickness direction N3, thereby fixing the position of the adapter 2 and the power rail 1 in the length direction N1.

[0094] In some embodiments, refer to Figure 10 and Figure 12 The first limiting mechanism 3 includes a buckle 31, a button 32, and an elastic element 33. The buckle 31 can move relative to the body 21 in the thickness direction N3 to achieve avoidance and engagement with the third limiting part 1181. The button 32 extends to the outside of the body 21 and is connected to the buckle 31. When the user applies external force to the button 32, the button 32 can drive the buckle 31 to move relative to the adapter 2 away from the power rail 1, that is, the button 32 can receive external force and retract into the body 21 (e.g., Figure 12 (As shown), to avoid the buckle 31 interfering with the insertion of the adapter 2. The elastic element 33 abuts between the body 21 and the buckle 31. The elastic element 33 is used to drive the buckle 31 to move relative to the adapter 2 towards the power rail 1. That is, the elastic element 33 is used to drive the part of the buckle 31 near the power rail 1 to protrude outward from the body 21. When the user's external force causes the buckle 31 to retract into the body 21, the elastic element 33 is compressed and deformed; after the adapter 2 is inserted into the power rail 1, the external force is removed, the elastic element 33 restores its deformation, and the restoring force of the elastic element 33 drives the part of the buckle 31 to protrude outward from the body 21. The buckle 31 engages with the third limiting part 1181 to fix the adapter 2 to the power rail 1.

[0095] In some embodiments, refer to Figure 4The first limiting mechanism 3 engages with the end of the power rail 1 away from the insertion port 112 in the width direction N2. That is, the adapter 2 is inserted from one end of the contact cavity 111 in the width direction N2, and the adapter 2 engages with the first limiting mechanism 3 from the other end of the contact cavity 111 in the width direction N2. The third limiting part 1181 and the insertion port 112 are respectively provided on both sides of the contact cavity 111 in the width direction N2. The operating space for forming the third limiting part 1181 and the operating space for opening the insertion port 112 do not interfere with each other, reducing the processing difficulty of the power rail 1.

[0096] In some embodiments, refer to Figure 8 and Figure 11 The main body 21 has a through first limiting hole 213 at one end near the card holder 22 in the thickness direction N3, that is, the first limiting hole 213 is opened through the bottom surface of the main body 21. The buckle 31 slides back and forth in the first limiting hole 213 along the thickness direction N3 to realize the extension and retraction of the buckle 31 relative to the main body 21. When the button 32 is not subjected to external force, part of the buckle 31 is located outside the main body 21, and the other part is located inside the main body 21. The buckle 31 slides back and forth in the first limiting hole 213, and the first limiting hole 213 is opened along the thickness direction N3. The degree of freedom of the buckle 31 in the circumferential direction is restricted within the first limiting hole 213. It should be noted that "circumferential direction" refers to the surrounding direction that surrounds the outline boundary of the first limiting hole 213. The buckle 31 maintains a high degree of coaxiality with the first limiting hole 213, thereby reducing the risk of buckle 31 shifting during reciprocating sliding, improving the stability of buckle 31 extending out of body 21, and facilitating stable and smooth engagement between the third limiting part 1181 and buckle 31.

[0097] In some embodiments, refer to Figure 8 and Figure 11 The main body 21 has a through second limiting hole 214 at one end in the width direction N2 away from the insertion port 112, that is, the second limiting hole 214 is formed through the side of the main body 21. The second limiting hole 214 extends in the thickness direction N3, that is, the second limiting hole 214 is approximately oblong in shape extending in the thickness direction N3. The button 32 passes through the second limiting hole 214, and the button 32 can move in the extending direction of the second limiting hole 214. That is, the button 32 is located at the bottom end of the second limiting hole 214 in the initial state (e.g., ...). Figure 11 Then, under the action of external force from the user, button 32 slides upward until the latch 31 retracts into the first limiting hole 213 (as shown). Figure 12(As shown). The fourth limiting part 311 slides back and forth within the first limiting hole 213. That is, the dimension of the first limiting hole 213 in the thickness direction N3 is related to the effective stroke of the buckle 31. By controlling the dimension of the first limiting hole 213 in the thickness direction N3, the movement path of the buckle 31 can be effectively controlled. The setting of the first limiting hole 213 improves the dimensional accuracy of the buckle 31's extension, so as to ensure the reliability of the connection and the smoothness of the installation between the first limiting mechanism 3 and the third limiting part 1181.

[0098] In some embodiments, refer to Figure 8 and Figure 11 The buckle 31 includes a fourth limiting part 311 and a mounting part 312. The fourth limiting part 311 is configured as a groove structure, and the groove opening of the fourth limiting part 311 is opened inward in the width direction N2. That is, the opening of the fourth limiting part 311 is opened towards the third limiting part 1181 in the width direction N2, so that the third limiting part 1181 can be inserted into the fourth limiting part 311. The connecting part 116 is disposed in the body 21, and the mounting part 312 is connected to the button 32. When the user applies external force to the button 32, the button 32 drives the mounting part 312 to slide back and forth in the thickness direction N3, thereby realizing the reciprocating sliding of the buckle 31 in the thickness direction N3.

[0099] In some embodiments, refer to Figure 5 and Figure 6 One end of the power track 1 is recessed in the width direction N2 to form a track groove 118. "Track groove 118" represents virtual space, and the position of track groove 118 is approximately... Figure 6 Within the area enclosed by the dashed frame. It should be noted that the track groove 118 can be unidirectionally open or, as shown in the schematic diagram of this application, bidirectionally open. The protruding edge forming the track groove 118 is the third limiting part 1181; that is, there can be one or two third limiting parts 1181. In the case where the track groove 118 is bidirectionally open, the track groove 118 has openings in both the width direction N2 and the thickness direction N3. In this embodiment, there is only one third limiting part 1181, and the fourth limiting part 311 abuts against the bottom edge of the third limiting part 1181 in the thickness direction N3.

[0100] Figure 13 This is a schematic diagram of the assembly of the first limiting mechanism 3 in another embodiment, with reference to... Figure 13When the track groove 118 has a one-way opening, the opening of the track groove 118 is located on the side away from the contact cavity 111 in the width direction N2. In this embodiment, two third limiting parts 1181 are provided. The track groove 118 forms a third limiting part 1181 on the top and bottom protrusions of the track groove 118 in the thickness direction N3, and the interval between the two third limiting parts 1181 in the thickness direction N3 constitutes the aforementioned track groove 118. In this embodiment, the fourth limiting part 311 can abut against the upper third limiting part 1181 in the thickness direction N3. At this time, the third limiting part 1181 is subjected to the pre-tension force of the elastic member 33. The fourth limiting part 311 can also abut against the lower third limiting part 1181 in the thickness direction N3. At this time, the third limiting part 1181 is subjected to the pre-pressure force of the elastic member 33.

[0101] In summary, regardless of the shape of the track groove 118, the fourth limiting part 311 of the first limiting mechanism 3 can extend into the track groove 118, and the fourth limiting part 311 abuts against one side of the third limiting part 1181 in the thickness direction N3.

[0102] It should be noted that the connecting surfaces of the third limiting part 1181 and the fourth limiting part 311 can be set as a plane as shown in the schematic diagram of this application. The third limiting part 1181 and the fourth limiting part 311 can also be set as a concave-convex structure that interlocks with each other in the thickness direction N3. Roller patterns can also be set on the connecting surfaces of the third limiting part 1181 and the fourth limiting part 311 to increase the friction between the third limiting part 1181 and the fourth limiting part 311, thereby limiting the degree of freedom of the fourth limiting part 311 in the length direction N1, thereby improving the fixed stability of the adapter 2 and the power rail 1 in the length direction N1, and reducing the risk of the adapter 2 being accidentally displaced by external force when it is powered on.

[0103] The first limiting part 117 and the second limiting part 224 are defined as power supply and disconnection structures, and the first limiting structure and the third limiting part 1181 are defined as installation and fixing structures. In some embodiments, the track socket can be provided with both power supply and disconnection structures and installation and fixing structures. The embodiments in the accompanying drawings of this application all show the case where power supply and disconnection structures and installation and fixing structures are provided at the same time. In some embodiments, only one of the power supply and disconnection structures and installation and fixing structures may be provided.

[0104] The following, combined with Figures 1 to 13 The implementation principle of the track socket in the embodiments shown in the accompanying drawings of this application will be explained as follows: When the adapter 2 is to be installed into the contact cavity 111 of the power rail 1, the user applies external force to the button 32, causing the button 32 to move upward in the thickness direction N3. The latch 31 retracts into the adapter 2. At this time, the body 21 has a flat lower surface, and the latch 31 does not interfere with the insertion of the adapter 2 in the width direction N2. After the adapter 2 is inserted from the insertion port 112, the user can release the button 32. The restoring force of the elastic element 33 causes the fourth limiting part 311 of the latch 31 to automatically extend out of the body 21, realizing the insertion and assembly of the adapter 2 and the power rail 1.

[0105] To achieve an electrical connection between adapter 2 and power rail 1, move adapter 2 to the left along the width direction N2 until the third limiting part 1181 is inserted into the fourth limiting part 311. At this time, adapter 2 is in the first position in the contact cavity 111. A set of second protrusions 2241 on the right end of the second limiting part 224 are engaged in a set of first grooves 1171 on the left end of the first limiting part 117. The contacts 223 of the card holder 22 are connected to the conductive parts 13 one by one. At this time, adapter 2 achieves an electrical connection with power rail 1, and the rail socket forms a power supply path.

[0106] To disconnect adapter 2 from power rail 1, move adapter 2 to the right in the width direction N2 until the side of the second support member 222 abuts against the inside of the connecting part 116, that is, adapter 2 is "fully inserted". At this time, the fourth limiting part 311 separates from the third limiting part 1181 in the width direction N2, and the contact 223 provided in the second support member 222 separates from the conductive member 13. Adapter 2 is disconnected from power rail 1, and adapter 2 will not be used "unloaded".

[0107] It should be noted that the relative position of the adapter 2 and the power rail 1 can be changed along the length direction N1 in various implementation scenarios. The frictional force between the first limiting part 117 and the second limiting part 224 is defined as F1, and the frictional force between the third limiting part 1181 and the fourth limiting part 311 is defined as F2. When F1 is less than F2, the user... Figure 9 In the state shown, move adapter 2 along the length direction N1.

[0108] When F1 is greater than F2, the user is Figure 4 and Figure 9In the indicated states, adapter 2 cannot be moved along the length direction N1. Even when powered off, adapter 2 maintains relative positional stability with respect to the power rail 1. When the user reconnects adapter 2 to an appliance at its original location, there is no need to readjust the position of adapter 2, making it convenient for the user. In this embodiment, if the user needs to adjust the position of adapter 2 along the length direction N1, external force can be applied to button 32 to retract the latch 31 into the body 21. Then, adapter 2 can be moved to the left along the width direction N2 until the first limiting part 117 separates from the second limiting part 224, thus enabling the adapter 2 to move along the length direction N1.

[0109] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
