DETAILED DESCRIPTION

[0039] The following embodiments are given in conjunction with the accompanying drawings to further illustrate the specific implementation of the present utility model. The protection scope of the present utility model is not limited to the description of the following embodiments.

[0040] like Figure 1 The figure shows a track socket according to this embodiment. The track socket includes a power track and at least one adapter 10. The adapter 10 is pluggable with the power track. An elongated insertion slot 12, parallel to the long side of the power track, is provided in the middle of the power track. Multiple adapters 10 can be inserted into the slot 12 at different positions, allowing for adjustment.

[0041] like Figure 2 The electric track of this embodiment is shown. The main body of the electric track is in the shape of an elongated strip. An elongated insertion slot 12 is provided on the upper end surface of the panel 1 along the longitudinal direction.

[0042] like Figure 3Shown is a power rail according to this embodiment. The rail includes a panel 1, an iron support structure 2, a terminal block assembly 3, a first cover plate 4, a mounting bracket 5, a first rear cover 6, an E-pole terminal block assembly 7, an L-pole terminal block assembly 8, and an N-pole terminal block assembly 9. The first cover plate 4 and the first rear cover 6 are detachably connected to jointly form a second housing 14; the second housing 14 and the panel 1 are detachably spliced, and a receiving cavity 13 is formed between the second housing 14 and the panel 1 for installing the terminal block assembly 3, the E-pole conductive sheet assembly 7, the L-pole conductive sheet assembly 8, and the N-pole conductive sheet assembly 9. The terminal block assembly 3 is installed between the first cover plate 4 and the panel 1, and the E-pole conductive sheet assembly 7, the L-pole conductive sheet assembly 8, and the N-pole conductive sheet assembly 9 are installed between the first rear cover 6 and the panel 1.

[0043] The L-pole conductive sheet assembly 8 and the N-pole conductive sheet assembly 9 are arranged side by side at intervals on both sides of the receiving cavity 13, and the E-pole conductive sheet assembly 7 is arranged below the gap between the L-pole conductive sheet assembly 8 and the N-pole conductive sheet assembly 9; the iron support structure 2 is arranged between the panel 1 and the L-pole conductive sheet assembly 8 and the N-pole conductive sheet assembly 9. The panel 1 and the iron support structure 2 are respectively provided with a long insertion groove 12 and a second insertion groove 21 along the long side direction of the panel 1 for the insertion of the adapter 10; the mounting bracket 5 is provided with screw holes, and screws fix the mounting bracket 5 to a wall or other installation positions through the screw holes. The second housing 14 is snap-connected to the mounting bracket 5 to fix the power rail as a whole to a wall or other installation positions; the terminal block assembly 3 is arranged at one end of the receiving cavity 13, and its bottom is provided with a first cover plate 4, which is conducive to disassembly or wiring. Of course, as other embodiments, the first cover plate 4 and the first rear cover 6 can also be integrally formed. The iron support structure 2 is located between the panel 1, the L-pole conductive sheet assembly 8, and the N-pole conductive sheet assembly 9, greatly improving the mechanical strength of the power rail; the mounting bracket 5 is an iron mounting bracket, which is located outside the first rear cover 6 and is used to fix the entire power rail to a wall. The panel 1 and the second housing 14 are detachably spliced, which is easy for part inspection and replacement; in addition, both the panel 1 and the second housing 14 are injection molded parts, playing an insulating role.

[0044] Preferably, as Figure 4 shown in the embodiment, the panel 1 is provided with a first installation groove 15 for accommodating the mounting bracket 5, a second installation groove 16 for accommodating the second housing 14 is provided in the first cavity, and a third installation groove 17 is further provided in the second installation groove 16. The receiving cavity 13 is formed between the third installation groove 17 and the second housing 14. The panel 1 completely covers the mounting bracket 5 and the second housing 14, which is beautiful and avoids the exposure of the mounting bracket.

[0045] As Figure 4As shown, the iron support structure 2 is limited and fixed between the panel 1, the L-pole conductive sheet assembly 8, and the N-pole conductive sheet assembly 9. Specifically, the panel 1 and the iron support structure 2 also cooperate to form an anti-fooling groove 19 on one side of the insertion slot 12 to prevent the adapter 10 from being reversely connected to the live and neutral wires of the power rail.

[0046] Specifically, as Figure 4 shown, the power rail of this embodiment, the L-pole conductive sheet assembly 8 and the N-pole conductive sheet assembly 9 are arranged in two copper part installation slots 811 with opposite openings; the E-pole conductive sheet assembly 7 is arranged in the gap formed between the two copper part installation slots 811; as Fig.10 shown in the embodiment, two anti-fooling grooves 19 are formed between the inner sides of the iron support structure 2 facing the L-pole conductive sheet assembly 8 and the N-pole conductive sheet assembly 9 and the L-pole conductive sheet assembly 8 and the N-pole conductive sheet assembly 9. The two anti-fooling grooves 19 are respectively located on both sides of the insertion slot 12. The width of the second insertion slot 21 of the iron support structure is greater than the width of the insertion slot 12 of the panel 1. The inner side of the panel 1 facing the iron support structure 2 is an asymmetric structure on both sides of the insertion slot 12, and only one side is provided with a blocking protrusion 11. The blocking protrusion 11 passes through the second insertion slot 21 and inserts into one of the anti-fooling grooves 19 to form a blocking structure, so that only one side of the accommodating cavity 13 is provided with an anti-fooling groove for cooperating with the anti-fooling protrusion on the adapter 10 to prevent the adapter 10 from being reversely connected to the live and neutral wires of the power rail. The blocking protrusion 11 serves to close one of the anti-fooling grooves 19 and also plays a role in fixing the iron mounting frame. Of course, as other embodiments, the anti-fooling groove 19 can also be realized in other ways.

[0047] As Figure 4 and Figure 7 shown, a long strip-shaped second insertion slot 21 is arranged on the upper end surface of the iron support structure 2 along the long side direction; iron support protrusion walls 22 are symmetrically arranged on both sides of the lower end surface of the iron support structure 2, and the iron support protrusion walls 22 on both sides are respectively buckled and limited on the insulating brackets 81 of the L-pole conductive sheet assembly 8 and the N-pole conductive sheet assembly 9. Specifically, the iron support protrusion walls 22 on both sides are embedded on the outer side of the connection between the dust-proof door installation slot 812 and the copper part installation slot 811, and the iron support structure 2 is positioned by the L-pole conductive sheet assembly 8 and the N-pole conductive sheet assembly 9. The iron support structure 2 plays a role in supporting the entire power rail; when the iron support structure 2 is correctly installed, the second insertion slot 21 is aligned with the position of the insertion slot of the panel 1.

[0048] Further, a plurality of limiting protrusions 18 are provided on the inner side of the panel 1 facing the iron support structure 2. Different from the blocking protrusions 11 being closely inserted into the insertion grooves 12, the limiting protrusions 18 are arranged at intervals with the insertion grooves 12. The iron support structure 2 is correspondingly provided with a plurality of limiting holes 28. The limiting protrusions 18 are inserted into the limiting holes 28 to play a positioning and limiting role. Obviously, some of the above limiting structures can be reduced according to needs, or other limiting structures can be added or adopted.

[0049] As Figure 3 and Figure 4 shown in the embodiments of, the mounting bracket 5 is arranged on the outer side of the second housing 14, away from the panel 1; the length of the mounting bracket 5 is less than the length of the second housing 14, and at least two mounting brackets 5 are arranged at intervals along the length direction of the second housing 14, and the second housing 14 is clamped with the at least two mounting brackets 5. Specifically, in combination with Figure 8 the first rear cover 6 in the second housing 14 of the embodiment, the second housing 14 is clamped with the mounting bracket 5 through the first rear cover 6. The first rear cover 6 is an open groove closed on three sides, including a bottom plate and three side walls; long strip-shaped first snap bosses 61 are symmetrically arranged on the outer sides of the two side walls along the long side direction. In combination with Figure 9 the mounting bracket 5 in the embodiment, the mounting bracket 5 is a U-shaped groove structure, including a bottom plate 51 and two opposite limiting baffles 52; second snap bosses 53 corresponding to the positions of the first snap bosses 61 are arranged on the limiting baffles 52; the second housing 14 and the mounting bracket 5 are clamped through the first snap bosses 61 and the second snap bosses 53 (see Figure 4 ). Of course, as other embodiments, a clamping groove may also be provided on the limiting baffle 52, or a clamping groove may be provided on the outer side of the second housing 14, and the snap boss is clamped and matched with the clamping groove.

[0050] Particularly, as Figure 9 shown, the bottom plate 51 is provided with an elastic piece 54 bent towards the inner side of the U-shaped groove structure, and the elastic piece 54 and the bottom plate 51 are integrally formed. With the design of the elastic piece 54, the clamping strength and stability of the mounting bracket 5 and the second housing 14 are enhanced. In this embodiment, the mounting bracket 5 is installed on the outer side of the second housing 14, and the operation is simple and it is easy to load and unload at any time.

[0051] As Figure 3 and Figure 5 shown in the embodiments, the terminal block assembly 3 includes an L-pole terminal, an N-pole terminal and an E-pole terminal for connecting conductors of an external power supply. Among them, the L-pole terminal and the N-pole terminal are on the same horizontal line, and the E-pole terminal is below the L-pole terminal and the N-pole terminal. There is a circular through hole in the center of the E-pole terminal. As Figure 5In the illustrated embodiment, the L-pole terminal is electrically connected to the conductive sheet of the L-pole conductive sheet assembly 8, the N-pole terminal is electrically connected to the conductive sheet of the N-pole conductive sheet assembly 9, and the E-pole terminal is electrically connected to the conductive sheet of the E-pole conductive sheet assembly 7 by screws.

[0052] As Figure 6 shown in the illustrated embodiment, the panel 1 of this power rail has a long insertion groove 12 along the long side direction on the upper end surface for the insertion of the adapter 10.

[0053] As Fig.10 and Figure 11 shown in the illustrated embodiment of the L-pole conductive sheet assembly 8, the structure of the N-pole conductive sheet assembly 9 is similar to that of the L-pole conductive sheet assembly 8. Both 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 installation groove 811 at the bottom and a dust-proof door installation groove 812 at the top; both the copper part installation groove 811 and the dust-proof door installation groove 812 are provided with openings facing the middle of the accommodation cavity 13. The conductive sheet 84 is installed in the copper part installation groove 811, and the elastic member 82 and the dust-proof door 83 are installed in the dust-proof door installation groove 812; the elastic members 82 of the L-pole conductive sheet assembly 8 and the N-pole conductive sheet assembly 9 respectively drive the corresponding dust-proof doors 83 to slide towards each other to close the insertion groove 12; the insulating bracket 81 is in one piece or spliced in sections.

[0054] As Figure 11 shown, the conductive sheet 84 includes two clamping pieces 841 arranged opposite to each other, and a fixing piece 842 connected between the two clamping pieces. The fixing piece 842 is fixedly connected to the copper part installation groove 811, and the middle parts of the two clamping pieces 841 bulge and bend towards each other to form a clamping gap. As Figure 3 and Figure 5 shown, the E-pole conductive sheet assembly 7 includes a long conductive sheet.

[0055] 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 method 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 method is that when the adapter 10 is inserted into the track to obtain power, when the sub-dust-proof door 810 driven by the adapter 10 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 10 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 10 is inserted, or generating a huge resistance to prevent the insertion of the adapter 10. Thus, when one sub-dust-proof door 810 is driven by the adapter 10, 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 10 will be appropriately retracted, so that the adapter 10 itself can be used to shield the insertion slot 12 area of the opened sub-dust-proof door 810 and block the entry of dust, oil stains and other objects, thereby protecting the cleanliness of the components inside the track socket.

[0056] Furthermore, the adapter 10 and the power track in this embodiment also have an anti-misinsertion function to prevent the L / N polarity on the adapter from being reversely connected to the L / N polarity on the power track.

[0057] Such as Fig.12The power rail of the illustrated embodiment provides a mounting method for the adapter 10 and the power rail. The adapter 10 includes a conductive sheet connecting portion 101 and a socket body 103, and the conductive sheet connecting portion 101 is connected to the socket body 103; an L-pole insert, an N-pole insert, and a ground-pole insert are provided in the conductive sheet connecting portion 101, and the ground-pole insert extends from the bottom of the conductive sheet connecting portion 101 and is electrically connected to the conductive sheet of the E-pole conductive sheet assembly 7. The L-pole insert and the N-pole insert are symmetrically arranged on both sides of the conductive sheet connecting portion 101 in a rotatable manner and can be rotated into and out of the conductive sheet connecting portion 101. The conductive sheet connecting portion 101 is in a plate-like structure. When the adapter 10 is not inserted into the power rail, the L-pole insert and the N-pole insert are located inside the conductive sheet connecting portion 101 and are respectively located on both sides of the ground-pole insert. When the conductive sheet connecting portion 101 of the adapter 10 passes through the insertion slot of the panel 1 and then rotates the rotating portion on the adapter 10 counterclockwise or clockwise by 90°, the L-pole insert and the N-pole insert are driven to rotate by 90° and extend out from the inside of the conductive sheet connecting portion. At this time, the N-pole and L-pole inserts 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.

[0058] Preferably, an anti-fooling protrusion 102 that rotates with the L-pole insert or the N-pole insert is provided in the conductive sheet connecting portion 101. Correspondingly, the inner surface of the panel 1 is an asymmetric structure along both sides of the insertion slot 12, and the anti-fooling groove 19 is provided only on one side.

[0059] When the conductive sheet connecting portion 101 of the adapter 10 is inserted into the insertion slot on the inner surface of the panel 1, it can only rotate in one direction. The anti-fooling protrusion 102 that rotates with the L-pole insert is fitted into the anti-fooling groove 19. 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 10 rotates in the wrong direction, since the anti-fooling groove 19 is not provided on the other side of the inner surface of the panel 1, 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.

[0060] The anti-fooling groove 19 of this embodiment is provided on the inner surface of the panel 1, and the anti-fooling protrusion 102 is located inside the conductive sheet connecting portion 101 of the adapter 10 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, and the overall appearance is beautiful.

[0061] Adopting the technical solution of the embodiment has the following beneficial effects compared with the prior art:

[0062] (1) The present utility model provides a power rail. An iron bracket is provided as an iron support structure between the panel, the L-pole conductive sheet assembly and the N-pole conductive sheet assembly, and it is fixed on the L-pole conductive sheet assembly and the N-pole conductive sheet assembly through the iron bracket convex walls designed at both ends thereof. With such a design, the installation strength of the product is enhanced, the deformation of the panel due to injection molding or assembly can be corrected, and the pressure generated by the adapter hook can be borne.

[0063] (2) The conductive sheet assembly provided by the present utility model is equipped with a dust-proof door, which can be used in cooperation with the adapter, improving the comfort of plugging and unplugging and greatly increasing the service life of the product.

[0064] (3) The housing of the power rail provided by the present utility model adopts a design of special anti-fooling grooves, which can be combined with the anti-fooling protrusions in the conductive sheet connection part of the adapter, easily solving the problem of incorrect insertion of the adapter polarity.
