[0042] As Figure 2Shown is a power rail according to this embodiment. The rail includes a first housing 1, an iron support structure 2, a mounting bracket 3, a terminal block assembly 4, a first cover plate 5, a first rear cover 6, an E-pole conductive sheet assembly 7, an L-pole conductive sheet assembly 8, and an N-pole conductive sheet assembly 9. The first cover plate 5 and the first rear cover 6 are detachably connected and together form a second housing 10.

[0043] The terminal block assembly 4, the E-pole conductive sheet assembly 7, the L-pole conductive sheet assembly 8, and the N-pole conductive sheet assembly 9 are installed in the accommodation cavity 101 between the second housing 10 and the mounting bracket 3. The iron support structure 2 matches the size of the mounting bracket 3 and is fixedly arranged on the top side of the mounting bracket 3 facing the first housing 1. The first housing 1 is snap-connected to the mounting bracket 3, and the iron support structure 2 is located between the mounting bracket 3 and the first housing 1.

[0044] The N-pole conductive sheet assembly 9 and the L-pole conductive sheet assembly 8 are arranged side by side at intervals on both sides of the accommodation cavity 101. The E-pole conductive sheet assembly 7 is arranged below the gap between the N-pole conductive sheet assembly 9 and the L-pole conductive sheet assembly 8. A long insertion slot 102 is provided on the first housing 1. The iron support structure 2 and the mounting bracket 3 are respectively provided with long second insertion slots 23 and third insertion slots 33 for the insertion of the adapter 14. The insertion slot 102 is directly opposite to the E-pole conductive sheet assembly 7. The terminal block assembly 4 is arranged at one end of the accommodation cavity 101 along the length direction, and its bottom is provided with the first cover plate 5, which is beneficial for removing the wiring. Of course, as other embodiments, the first cover plate 5 and the first rear cover 6 can also be integrally formed. The iron support structure 2 is located between the first housing 1 and the mounting bracket 3 to play a supporting role. While strengthening the installation strength of the product, it also strengthens the strength of the product at the insertion slot, can correct the deformation of the first housing and the mounting bracket due to injection molding or assembly, and can withstand the pressure generated by the adapter hook. The mounting bracket 3 and the second housing 10 are detachably spliced. The first housing 1, the second housing 10, and the mounting bracket 3 are injection molded parts and play an insulating role.

[0045] As Figure 4 shown in the embodiment of the power rail, the rail accommodation cavity 101 formed by the first housing 1 and the mounting bracket 3 is divided into two asymmetric spaces by the first cover plate 5 and the first rear cover 6; as Figure 10 shown in the embodiment, the structure of the second housing 10 of the power rail is provided. Here, the second housing 10 is formed by connecting the first cover plate 5 and the first rear cover 6. Vertical limiting structures are symmetrically provided at the edges of the first cover plate 5 and the first rear cover 6, thereby forming a first accommodation groove 1001 and a second accommodation groove 1002. The first accommodation groove 1001 cooperates with the mounting bracket 3 to accommodate the terminal block assembly 4, and the second accommodation groove 1002 cooperates with the mounting bracket 3 to arrange the E-pole conductive sheet assembly 7, the L-pole conductive sheet assembly 8, and the N-pole conductive sheet assembly 9, playing a protective role.

[0046] As Figure 6 、 14 shown in the structure of the terminal block assembly 4, the terminal block assembly 4 includes an L-pole terminal 41, an N-pole terminal 42, and an E-pole terminal 43 for connecting conductors of an external power supply. Among them, the L-pole terminal 41 and the N-pole terminal 42 are on the same horizontal line, and the E-pole terminal 43 is below the L-pole terminal 41 and the N-pole terminal 42. There is a circular through-hole 431 in the center of the E-pole terminal 43. As Figure 6 shown in the embodiment, the L-pole terminal 41 is electrically connected to the L-pole conductive sheet assembly 8, the N-pole terminal 42 is electrically connected to the N-pole conductive sheet assembly 9, and the E-pole terminal 43 is electrically connected to the E-pole conductive sheet assembly 7 by screws. The E-pole conductive sheet assembly 7 includes a strip-shaped conductive sheet, on which circular through-holes 843 are equidistantly arranged.

[0047] As Figure 7 shown in the embodiment of the structure of the first housing 1. Along the long side direction at the top of the first housing 1, there is a strip-shaped insertion slot 102 for the insertion of the adapter 14; on its inner surface, symmetrically arranged raised bayonets 13 are provided on both sides of the insertion slot 102, and strip-shaped through-holes 24 are provided at corresponding positions of the iron support structure 2 (as Figure 5 and Figure 8 ), and a card slot 35 is provided at the corresponding position of the mounting bracket 3; the raised bayonets 13 pass through the strip-shaped through-holes 24 and are clamped in the card slot 35 (as Figure 9 ) to fix the first housing 1 on the mounting bracket 3; in addition, on the side wall of the mounting bracket 3 of the mounting bracket, clamping positions 31 are symmetrically arranged along the long side direction, a disassembly slot is provided adjacent to the clamping position 31, and a boss 32 is provided in the disassembly slot; at the position corresponding to the clamping position along the long side direction of the side of the first housing 1, a buckle 11 is provided, and a notch 12 is provided adjacent to the buckle 11. The buckle 11 is clamped with the clamping position 31, and the notch 12 is arranged corresponding to the boss 32, and a disassembly gap is formed between the notch 12 and the boss 32, which can be pried by a screwdriver for the disassembly and installation of components. This embodiment adopts a dual design of the raised bayonet 13 and the buckle 11, making the first housing 1 more tightly installed on the mounting bracket 3.

[0048] As Figure 8The illustrated embodiment is the structure of the iron support structure 2. A second insertion slot 23 corresponding to the insertion slot 102 of the first housing is provided at the center line of the iron support structure 2 for plugging in the adapter 14. A long through hole 24 adapted to the size of the convex bayonet 13 of the first housing is provided on the iron support structure 2 to facilitate the passage of the convex bayonet 13; symmetric grooves 21 are provided along the long side direction of its edge for receiving the buckling positions 11 of the first housing; in addition, the iron support structure 2 is also symmetrically provided with first through holes 22 along the long side direction. Screws pass through the first through holes 22 and the second through holes 34 on the mounting bracket to fix the iron support structure 2 and the mounting bracket 3 on the wall (such as Figure 9 ). Specifically, the widths of the iron support structure 2 and the mounting bracket 3 are greater than the width of the second housing 10. Mounting bracket flanks 36 protruding from the second housing 10 are provided on both sides of the mounting bracket 3 in the width direction, and iron support structure flanks 26 protruding from the second housing 10 are provided on both sides of the iron support structure 2 in the width direction. The iron support structure 2 is provided with first through holes 22 on the iron support structure flanks 26, and second through holes 34 are provided at corresponding positions on the mounting bracket flanks 36 of the mounting bracket 3 for the screws for installing the power track to pass through and install the power track on the cavity. Preferably, a mounting groove 25 is provided on the iron support structure flank 26, and the first through hole 22 is arranged in the mounting groove 25 to accommodate the screw head of the screw so that it does not protrude from the iron support structure 2. The specific installation method of the iron support structure 2 and the mounting bracket 3 is as shown in Figure 4 . The iron support structure 2 is located between the first housing 1 and the mounting bracket 3, and its structure matches that of the mounting bracket 3, and it is installed on the mounting bracket 3 by a snap connection method.

[0049] The iron support structure in this embodiment is made of iron material and adopts the design of an iron bracket, which not only strengthens the strength required for the installation of the power track but also strengthens its strength at the insertion slot 102, can correct the deformation of the first housing 1 and the mounting bracket 3 caused by injection molding or assembly, and can withstand the pressure generated by the hook of the adapter 14.

[0050] Such as Figure 9 The illustrated embodiment is the structure of the mounting bracket 3. The mounting bracket 3 is symmetrically provided with buckling positions 31 along the long side direction. The buckling positions 11 on the first housing 1 are finally fixed on the buckling positions 31 of the mounting bracket 3 through the grooves 21 on the iron support structure 2. A disassembly slot is provided adjacent to the buckling position 31, and a convex platform 32 is provided in the disassembly slot, which is engaged with the notch 12 on the first housing 1 to assist in the installation of the first housing 1.

[0051] Such as Figure 11 、 12An embodiment of the L-pole conductive sheet assembly 8 is shown. The structure of the N-pole conductive sheet assembly 9 is similar to that of the L-pole conductive sheet assembly 8. The L-pole conductive sheet assembly 8 and the N-pole conductive sheet assembly 9 each include: an insulating bracket 81, an elastic member 82, a dust-proof door 83, and a conductive sheet 84; the insulating bracket 81 includes a copper part mounting groove 811 at the bottom and a dust-proof door mounting groove 812 at the top; both the copper part mounting groove 811 and the dust-proof door mounting groove 812 are provided with openings facing the middle of the accommodating cavity 101. The conductive sheet 84 is installed in the copper part mounting groove 811, and the elastic member 82 and the dust-proof door 83 are installed in the dust-proof door mounting groove 812; the elastic members 82 of the L-pole conductive sheet assembly 8 and the N-pole conductive sheet assembly 9 drive the corresponding dust-proof doors 83 to slide towards each other to close the insertion slot 102; the insulating bracket 81 is in one piece or spliced in segments.

[0052] As Figure 12 shown, the conductive sheet 84 includes two clamping pieces 841 arranged oppositely, and a fixing piece 842 connected between the two clamping pieces. The fixing piece 842 is fixedly connected to the copper part mounting groove 811, and the middle parts of the two clamping pieces 841 bulge and bend towards each other to form a clamping gap.

[0053] The dust-proof door 83 includes a plurality of sub-dust-proof doors 810 arranged side by side, and a plurality of elastic members 82 are respectively connected to the plurality of sub-dust-proof doors 810. Preferably, a linkage structure is provided between adjacent sub-dust-proof doors 810. The linkage structure includes a groove 831 and a protrusion 832; the groove 831 and the protrusion 832 are respectively arranged on both sides of each sub-dust-proof door 810; the protrusion 832 of the sub-dust-proof door 810 is arranged in the groove 831 of the adjacent sub-dust-proof door 810, and one sub-dust-proof door 810 can be linked with the protrusion 832 of the adjacent sub-dust-proof door 810 through the groove 831. One implementation mode is the synchronous movement between the sub-dust-proof doors 810, and the groove 831 and the protrusion 832 are connected in an interference fit. Preferably, another mode is that when the adapter 14 is inserted into the track to take power, when the sub-dust-proof door 810 driven by the adapter 14 drives the adjacent sub-dust-proof door 810, the distance that the adjacent linked sub-dust-proof door 810 slides backward is less than the distance that the sub-dust-proof door 810 driven by the adapter 14 slides. For example, in the moving direction of the sub-dust-proof door 810, the width of the protrusion 832 is less than the width of the groove 831, that is, there is a linkage gap between the protrusion 832 and the groove 831. This can prevent all the sub-dust-proof doors 810 from being fully opened when the adapter 14 is inserted, or generating a huge resistance to prevent the insertion of the adapter 14. In this way, when a sub-dust-proof door 810 is driven by the adapter 14, it needs to move the distance of the linkage gap before driving the adjacent sub-dust-proof door 810 to move. With the setting of a suitable linkage gap, the number of adjacent linked sub-dust-proof doors 810 can be controlled within a small range, and only the dust-proof doors in the area covered by the adapter 14 will be appropriately retracted, so that the adapter 14 itself can be used to shield the insertion slot 102 area of the opened sub-dust-proof door 810, blocking the entry of dust, oil stains and other objects, thereby protecting the cleanliness of the components inside the track socket.

[0054] As Figure 6 shown in the embodiment, the E-pole conductive sheet assembly 7 includes a strip-shaped conductive sheet, and circular through holes 843 are equidistantly arranged on the conductive sheet. As Figure 13As shown, a circular through-hole 431 adapted to the size of the circular through-hole 843 is provided on the E-pole terminal 43. After any one of the circular through-holes 843 near the end of the conductive sheet is aligned with the circular through-hole 431 on the E-pole terminal, a screw sequentially passes through the circular through-hole 843 and the circular through-hole 431 to fix the conductive sheet on the E-pole terminal 43. In addition, a plurality of circular through-holes 431 are provided on the conductive sheet of the E-pole conductive sheet assembly 7 to assist in positioning the adapter 14 and also play a certain role in prompting the adapter 14 to be installed in place. When the adapter 14 is inserted into the insertion slot 102 of the power rail, the E-pole insertion piece of the adapter 14 that slides along the rail can be slightly inserted into the circular through-hole 843, with a slight jamming to prompt installation in place. Of course, the circular through-hole 843 may not be provided. Further, the adapter 14 and the power rail of this embodiment also have an anti-fooling function to prevent the L / N polarity on the adapter from being reversely connected to the L / N polarity on the power rail.

[0055] As Figure 13 shown in the embodiment, the power rail provides an installation method for the adapter 14 and the power rail. In this embodiment, the upper end surface of the mounting frame 3 of the power rail facing both sides of the accommodation cavity 101 is an asymmetric structure, and an anti-fooling groove 1021 is provided only on one side. As Figure 13 shown in the embodiment, the adapter 14 includes a conductive sheet connecting portion 142 and a socket body 141, and the conductive sheet connecting portion 142 is connected to the socket body 141; an L-pole insertion piece, an N-pole insertion piece, and a ground-pole insertion piece are provided in the conductive sheet connecting portion 142, and the ground-pole insertion piece extends from the bottom of the conductive sheet connecting portion 142 and is electrically connected to the conductive sheet of the E-pole conductive sheet assembly 7. The L-pole insertion piece and the N-pole insertion piece are symmetrically arranged on both sides of the conductive sheet connecting portion 142 in a rotatable manner and can rotate into and out of the conductive sheet connecting portion 142. The conductive sheet connecting portion 142 is in a plate-like structure. Figure 13 For the cross-sectional view in the width direction thereof, when the adapter 14 is not inserted into the power rail, the L-pole insertion piece and the N-pole insertion piece are located inside the conductive sheet connecting portion 142 and are respectively located on both sides of the ground-pole insertion piece. When the conductive sheet connecting portion 142 of the adapter 14 sequentially passes through the insertion slot of the first housing 1, the second insertion slot of the iron support structure 2, and is inserted into the third insertion slot on the mounting frame 3, when the rotating portion on the adapter 14 is rotated 90° counterclockwise or clockwise, the L-pole insertion piece and the N-pole insertion piece are driven to rotate 90° and extend out from inside the conductive sheet connecting portion 142. At this time, the N-pole and L-pole insertion pieces are unfolded and are respectively electrically connected to the conductive sheets of the N-pole conductive sheet assembly 9 and the L-pole conductive sheet assembly 8.

[0056] Preferably, an anti-fooling protrusion 143 that rotates with the L-pole insertion piece or the N-pole insertion piece is provided in the conductive sheet connecting portion 142. Correspondingly, both sides of the third insertion slot 33 on the mounting frame 3 are of an asymmetric structure, and an anti-fooling groove 1021 is provided only on one side.

[0057] When the conductive sheet connecting part 142 of the adapter 14 is inserted into the third insertion slot 33 on the mounting bracket 3, it can only rotate in one direction. The anti-fooling bump 143 that rotates with the L-pole insert fits into the anti-fooling groove 1021. The L-pole insert is inserted into the conductive sheet of the L-pole conductive sheet assembly 8, and the N-pole insert is inserted into the conductive sheet of the N-pole conductive sheet assembly 9. If the adapter 14 rotates in the wrong direction, since the anti-fooling groove 1021 is not provided on the other side of the mounting bracket 3, the L-pole insert and the N-pole insert are limited and cannot be rotated out, avoiding the reverse connection of the live wire and the neutral wire, that is, avoiding the connection between the L-pole insert and the conductive sheet of the N-pole conductive sheet assembly 9, and the connection between the N-pole insert and the conductive sheet of the L-pole conductive sheet assembly 8, ensuring the safety of electricity use.

[0058] In this embodiment, the anti-fooling groove 1021 is provided on the mounting bracket 3, and the anti-fooling bump 143 is located inside the conductive sheet connecting part 142 of the adapter 14 and rotates with the L-pole insert or the N-pole insert. The anti-fooling structure is located inside the product, which can not only avoid the reverse connection of the live wire and the neutral wire, but also does not affect the external structure of the product, making the overall appearance more beautiful.
