Abstract
Description
Technical Field
[0001] This application relates to the technical field of track sockets, and in particular to a reverse-insertion-proof track socket, which achieves the function of preventing the adapter from being inserted into the power rail for power supply in the forward direction and preventing it from being inserted into the reverse direction through structural design. Background Technology
[0002] Track sockets are a new type of socket product, mainly consisting of a power track and an adapter. The power track, also known as a power rail, is typically installed on walls, desktops, or other mounting surfaces. A mounting plate is usually provided on the back of the power track, which is fixedly installed on the mounting surface to ensure the power track is securely mounted.
[0003] Traditional track sockets typically lack reverse insertion protection when the adapter is plugged into the power rail. Users may accidentally insert the adapter in the wrong direction, causing the power arm and outlet to malfunction, resulting in reversed live and neutral wires, preventing normal power supply, or creating safety hazards. While some foolproof designs exist in existing technologies, they are complex or rely on specific components, making it difficult to balance flexible installation with high reliability. Therefore, there is an urgent need for a track socket design that is simple in structure and provides effective reverse insertion protection. Utility Model Content
[0004] A reverse-insertion-proof rail socket is provided, which solves the problem of reverse connection of live and neutral wires caused by reverse insertion of the adapter into the power rail through the biased and foolproof mating part design between the adapter and the power rail.
[0005] The anti-reverse insertion rail socket provided in this application adopts the following technical solution:
[0006] An anti-reverse insertion rail socket includes an adapter with a foolproof anti-misalignment component on one side of its base; a power rail including a rail body and a mounting back plate detachably mounted on the bottom of the rail body, wherein one side of the mounting back plate or the rail body has a mating component whose shape is complementary to the foolproof anti-misalignment component; when the adapter is inserted in the correct direction, the foolproof anti-misalignment component and the mating component form a plug-in engagement, allowing the adapter to be fully inserted and positioned for power access; when the adapter is inserted in the reverse direction, the foolproof anti-misalignment component interferes with the side wall of the power rail without the mating component, preventing the adapter from being fully inserted.
[0007] Optionally, the track body includes a conductive part and a wiring terminal. The inner peripheral wall of the conductive part forms a plug-in cavity, and power-taking ports are symmetrically opened on both sides of its inner wall. When the lower base of the adapter is inserted into the plug-in cavity, its power-taking arm passes through the power-taking port and extends into the conductive part to take power.
[0008] Optionally, the mating component is a groove or a convex plate structure, provided on the inner wall of one side of the mounting back plate or conductive part;
[0009] The anti-mistake component is a convex plate or groove structure, which is complementary in shape to the mating component.
[0010] Optionally, when the mating part is a groove, it is provided with a limiting ridge, and the end of the anti-fooling part abuts against the limiting ridge to position the insertion depth of the adapter.
[0011] Optionally, when the mating component is a protruding plate, it is located on one side of the inner wall of the conductive part and occupies part of the insertion cavity space, and the height of the protruding plate is lower than the position of the power outlet.
[0012] Optionally, when the adapter is inserted in reverse, interference between the foolproof part and the side wall without a mating part causes the power-taking arm to misalign with the power-taking port, preventing the power-taking arm from passing through the power-taking port and extending into the conductive part to take power.
[0013] Optionally, the mounting backplate is detachably connected to the track body via magnetic attraction, and the width of the backplate cavity is smaller than the width of the insertion cavity.
[0014] In summary, this application includes at least one of the following beneficial technical effects:
[0015] 1. A physical anti-misalignment structure is formed through the offset design of the anti-misalignment component and the mating component. When the adapter is inserted in the correct direction, the complementary convex and concave structure achieves precise guidance and depth limiting (such as the limiting ridge design), ensuring that the power arm and the power outlet are perfectly aligned; when inserted in the reverse direction, the anti-misalignment component and the side wall of the track form an interference barrier, forcibly causing the power arm and the power outlet to be misaligned, thus physically eliminating the risk of reverse connection of the live and neutral wires, which is more reliable and durable than traditional electronic reverse connection protection solutions;
[0016] 2. The mating parts can be flexibly integrated into the conductive parts of the mounting backplate or track body, and the adapter's foolproof parts support interchangeable convex / recessed designs. This modular structure allows the product to adapt to different track specifications, and users can choose between a separate backplate or an integrated track solution depending on the installation scenario, expanding the product's applicability. Meanwhile, the magnetic backplate design ensures stable track installation while supporting quick disassembly and maintenance.
[0017] 3. The mechanical cooperation between the anti-misalignment component and the mating component achieves dual functions simultaneously: on the one hand, the insertion of the convex plate and the groove itself constitutes an anti-reverse insertion mechanism with zero additional cost; on the other hand, the abutment between the limiting ridge and the end of the anti-misalignment component can precisely control the insertion depth, ensuring that the power arm is always aligned with the optimal contact position of the power outlet, avoiding the poor contact problem caused by excessive / shallow insertion in traditional rail sockets, and extending the service life of the socket.

Detailed Implementation
[0026] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0027] Example 1:
[0028] The following is in conjunction with the appendix Figure 1-5 An anti-reverse insertion track socket disclosed in Embodiment 1 of this application will be described.
[0029] Reference Figure 1 A reverse-insertion-proof rail socket includes a power rail 200 and an adapter 100 detachably mounted on the power rail 200. For a power rail 200, the number of adapters 100 mounted thereon can be one, two, or more. Figure 1 The number of adapters 100 is shown as two. Both adapters 100 are detachably mounted on the power rail 200 and draw power from the power rail 200.
[0030] Each adapter 100 includes an upper base 110 and a lower base 120. (See reference...) Figure 1 and Figure 2The upper base 110 of the adapter 100 is cylindrical, with a socket on its top end for inserting a plug of an electrical appliance to draw power. The lower base 120 of the adapter 100 is approximately rectangular with rounded corners; its top end is expanded to a cylindrical shape to fit and connect with the bottom end of the upper base 110. A power-drawing arm 121 is provided inside the lower base 120 of the adapter 100, as shown in the reference... Figure 1 and Figure 2 The number of power take-off arms 121 is set to two. When the upper base 110 of the adapter 100 is rotated clockwise, the power take-off arms 121 are extended through the internal transmission mechanism; when rotated counterclockwise, the power take-off arms 121 are retracted through the internal transmission mechanism.
[0031] The lower base 120 of the adapter 100 has a single-sided anti-fooling component 1 integrated on its bottom surface, as shown in the reference. Figure 2 The anti-mistake component 1 is a convex plate structure, and the outer edge sidewall of the anti-mistake component 1 is flush with the rectangular rounded corner structure surface that is close to it.
[0032] Reference Figure 1 and Figure 3 The electric track 200 includes a track body 210 and a mounting back plate 220 installed at the bottom of the track body 210. The mounting back plate 220 is fixedly installed on the mounting surface by fasteners such as screws, thus realizing the installation of the mounting back plate 220 on the mounting surface. The electric track 200 is magnetically installed on the mounting back plate 220, thus realizing the installation of the electric track 200 on the mounting surface.
[0033] Reference Figure 1 and Figure 4 The track body 210 includes a terminal block 212 and a conductive part 211 connected to the terminal block 212. The terminal block 212 is formed into a rectangular rounded corner structure, and the conductive part 211 is formed into a U-shape. The terminal block 212 is connected to the U-shaped opening end of the conductive part 211. The two are assembled to form an approximately ring-shaped track body 210. One end of the terminal block 212 is connected to an external power source, and the other end is connected to a conductive conductor inside the conductive part 211, so that the conductive part 211 is energized.
[0034] Reference Figure 1 and Figure 4The conductive part 211 has two sets of parallel copper strips embedded inside as conductive conductors, which are connected to the live wire and neutral wire respectively through the terminal 212. The power outlet 4 corresponds to the position of the copper strips. A plastic insulating bracket is provided between the conductive conductor and the conductive part 211 to achieve electrical isolation between the conductive part 211 and the conductive conductor. The cavity formed by the inner peripheral wall of the U-shaped conductive part 211 is the insertion cavity 3. Power outlets 4 are opened on the inner peripheral walls on both sides of the conductive part 211. The opening of the power outlet 4 corresponds to the conductive conductor inside the conductive part 211. The power outlet arm 121 of the adapter 100 can extend into the conductive part 211 through the power outlet 4 to contact the conductive conductor and draw power.
[0035] Reference Figure 1 and Figure 3 The mounting backplate 220 and the conductive part 211 have a U-shaped overall structure. Multiple magnets are fixed to the bottom of the conductive part 211 along its extension direction using screws. The mounting backplate 220 is a magnetic metal plate, magnetically attached to the bottom of the conductive part 211. The cavity formed in the center of the mounting backplate 220 is called the backplate cavity 6, and the width of the backplate cavity 6 is slightly smaller than the width of the insertion cavity 3. When the adapter 100 is installed on the power rail 200 to draw power, its lower base 120 is inserted into the insertion cavity 3, and its bottom abuts against the mounting backplate 220.
[0036] The inner wall of the mounting back plate 220 has a mating part 2 formed on one side along its own length direction, as shown in the figure. Figure 2 The mating part 2 is set as a groove, and its opening is set towards the back plate cavity 6 and the insertion cavity 3.
[0037] Reference Figure 4 When the adapter 100 is inserted into the power rail 200 in the forward direction to draw power, the anti-foolproof plate 1 of the lower base 120 of the adapter 100 is placed in the groove fitting 2 of the mounting back plate 220, and the side of the lower base 120 of the adapter 100 without the anti-foolproof plate 1 abuts against the side of the mounting back plate 220 facing the conductive part 211. At this time, the power-drawing arm 121 of the adapter 100 is aligned with the power-drawing port 4 of the conductive part 211, and the power-drawing arm 121 extends from the lower base 120 and extends into the conductive part 211 to draw power.
[0038] Reference Figure 5 When the adapter 100 is inserted into the power rail 200 in reverse to draw power, the protruding end of the lower base 120 of the adapter 100 abuts against the side of the mounting back plate 220 without the groove mating part 2, and the side of the lower base 120 of the adapter 100 without the anti-fooling part 1 is suspended in the insertion cavity 3. At this time, the adapter 100 cannot be fully inserted into the insertion cavity 3, and consequently, the power-drawing arm 121 of the adapter 100 is misaligned with the power-drawing port 4 of the rail body 210, and the power-drawing arm 121 of the adapter 100 cannot unfold to extend into the power-drawing port 4 to draw power.
[0039] Reference Figure 3 and Figure 4 The groove fitting 2 is also provided with a limiting ridge 5, which extends along the length of the groove fitting 2 and is set to the same length as the groove fitting 2. The limiting ridge 5 is integrally set inside the mounting back plate 220, and the side of the limiting ridge 5 away from the track body 210 is flush with the side of the mounting back plate 220 away from the track body 210.
[0040] Reference Figure 4 When the adapter 100 is inserted into the power rail 200 in the forward direction to draw power, the anti-foolproof part 1 of the lower base 120 of the adapter 100 is placed in the groove fitting part 2 of the mounting back plate 220. The end of the anti-foolproof part 1 abuts against the side wall of the limiting ridge 5 facing the rail body 210, and the side of the lower base 120 of the adapter 100 without the anti-foolproof part 1 abuts against the side of the mounting back plate 220 facing the conductive part 211. At this time, the power-drawing arm 121 of the adapter 100 is aligned with the power-drawing port 4 of the conductive part 211. The power-drawing arm 121 extends from the lower base 120 and extends into the conductive part 211 to draw power.
[0041] The limiting ridge 5 supports and engages with the anti-fooling component 1, and positions the insertion depth of the adapter 100 in the plug cavity 3, so as to ensure that after the adapter 100 is inserted into the power rail 200, its power taking arm 121 is aligned with the power taking port 4 opened on the power rail 200.
[0042] The implementation principle of the anti-reverse insertion rail socket in Embodiment 1 of this application is as follows: by setting an anti-foolproof component 1 on the lower base 120 of the adapter 100 and setting a mating component 2 on the mounting back plate 220 of the power rail 200, when the adapter 100 is inserted into the power rail 200 in the forward direction, the anti-foolproof component 1 is placed inside the mating component 2, and the end of the anti-foolproof component 1 abuts against the limiting ridge 5 inside the mating component 2. At this time, the power taking arm 121 of the adapter 100 is facing the power taking port 4 of the power rail 200, and the power taking arm 121 of the adapter 100 can extend into the conductive part 211 through the power taking port 4 to take power. When the adapter 100 is inserted into the power rail 200 in reverse, the anti-fooling component 1 is pressed against the side of the mounting back plate 220 where the mating component 2 is not provided. The power taking arm 121 of the adapter 100 is misaligned with the power taking port 4 of the power rail 200, so the power taking arm 121 of the adapter 100 cannot extend out of the power rail 200 to take power, thereby realizing the anti-reverse insertion of the adapter 100 on the power rail 200.
[0043] Example 2:
[0044] The following description, in conjunction with Appendix 6, describes an anti-reverse insertion track socket disclosed in Embodiment 2 of this application.
[0045] Example 2 has a basically the same structure as Example 1. The following mainly describes the differences:
[0046] The foolproof part 1 on the adapter 100 can also be configured as a groove structure, and the mating part 2 on the power rail 200 can also be configured as a convex plate structure.
[0047] That is, a groove anti-fooling element 1 is formed on one side of the bottom surface of the lower base 120 of the adapter 100, as shown in the figure. Figure 6 The groove anti-fouling component 1 occupies part of the rectangular rounded corner structure surface.
[0048] A protruding plate fitting 2 is provided on one side of the end face of the mounting back plate 220 that covers the plug-in cavity 3. The protruding plate fitting 2 extends along the length of the mounting back plate 220, protrudes from the end face of the mounting back plate 220, and occupies part of the space of the plug-in cavity 3. The protruding plate fitting 2 also abuts against the inner peripheral wall of the conductive part 211. It is worth noting that the height of the protruding plate fitting 2 is lower than the depth of the plug-in cavity 3 and lower than the height of the power outlet 4 opened in the cavity wall of the plug-in cavity 3, ensuring that the adapter 100 can be inserted normally.
[0049] When the adapter 100 is inserted into the power rail 200 in the forward direction to draw power, the protruding plate fitting 2 on the mounting back plate 220 is placed in the anti-fooling part 1 of the adapter 100 groove, and the side of the lower base 120 of the adapter 100 without the anti-fooling part 1 abuts against the side of the mounting back plate 220 facing the conductive part 211. At this time, the power-drawing arm 121 of the adapter 100 is aligned with the power-drawing port 4 of the conductive part 211, and the power-drawing arm 121 extends from the lower base 120 and extends into the conductive part 211 to draw power.
[0050] When the adapter 100 is inserted into the power rail 200 in reverse to draw power, the end of the protruding plate mating part 2 on the mounting back plate 220 abuts against the side of the lower base 120 of the adapter 100 without the groove anti-foolproof part 1, and the side of the lower base 120 of the adapter 100 without the anti-foolproof part 1 is suspended in the insertion cavity 3. At this time, the adapter 100 cannot be fully inserted into the insertion cavity 3, and consequently, the power-drawing arm 121 of the adapter 100 is misaligned with the power-drawing port 4 of the rail body 210, and the power-drawing arm 121 of the adapter 100 cannot unfold to extend into the power-drawing port 4 to draw power.
[0051] Example 3:
[0052] The following is in conjunction with the appendix Figure 7 An anti-reverse insertion track socket disclosed in Embodiment 3 of this application will be described.
[0053] Example 3 has a basically the same structure as Example 2. The following mainly describes the differences:
[0054] The protruding plate fitting 2 is integrally formed on one side of the inner peripheral wall of the conductive part 211, and occupies part of the space of the insertion cavity 3. Its position is the same as that of the protruding plate fitting 2 on the conductive part 211 in Embodiment 2.
[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application, without departing from the core design of this application, should be covered within the scope of protection of this application.
