Detailed implementation manners

[0036] The following embodiments given in conjunction with the drawings further illustrate the detailed implementation manners of the present utility model. The protection scope of the present utility model is not limited to the descriptions of the following embodiments.

[0037] As Figure 1Shown is an orbital socket according to this embodiment. The orbital socket includes a power rail and at least one adapter 9. The adapter 9 is pluggable into the power rail. A long strip-shaped insertion slot 35 parallel to the long side direction of the power rail is provided at the middle position of the power rail, which can be used to insert multiple adapters 9. The adapter 9 can be inserted from different positions of the insertion slot 35 and the position of the adapter 9 can be adjusted.

[0038] As Figure 11 Shown is a power rail according to this embodiment. The rail includes a decorative piece 1, a mounting bracket 2, a housing 3, a terminal block assembly 4, a first cover plate 5, an N-pole conductive sheet assembly 6, an L-pole conductive sheet assembly 7, and a screw 8. The N-pole conductive sheet assembly 6 and the L-pole conductive sheet assembly 7 are placed side by side at intervals in the housing 3. The terminal block assembly 4 is provided at one end of the housing 3, and a first cover plate 5 is provided at the bottom of the terminal block assembly 4. The decorative piece 1 and the mounting bracket 2 form a mounting and sealing assembly provided on both sides of the housing to play a role in fixing and decoration.

[0039] Combined with Figure 3 For the housing 3 of the power rail according to this embodiment, the housing 3 is an integral metal housing. The interior of the housing 3 contains a hollow cavity 33. A long strip-shaped insertion slot 35 is provided along the long side direction of the housing 3 at the top. The insertion slot 35 communicates with the hollow cavity 33 and divides the hollow cavity 33 into a first conductive cavity 311 and a second conductive cavity 312. The L-pole conductive sheet assembly 7 and the N-pole conductive sheet assembly 6 are respectively installed in the first conductive cavity 311 and the second conductive cavity 312.

[0040] As Figure 2 And Figure 8 For the structure shown, the terminal block assembly 4 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. The L-pole terminal is electrically connected to the L-pole conductive sheet assembly 7, the N-pole terminal is electrically connected to the N-pole conductive sheet assembly 6, and the E-pole terminal is electrically connected to the housing 3 through the screw 8. Specifically, the screw 8 fixes it to the metal housing 3 through the circular through-hole in the center of the E-pole terminal for grounding. With the design of this embodiment, while the screw 8 fixes the E-pole terminal to the metal housing 3, it also plays a role in grounding, simplifying the installation steps and reducing the assembly of parts.

[0041] The power rail of this embodiment adopts the design of an integrated metal housing, which is highly reliable, beautiful, simple and convenient. Moreover, the E-pole terminal of the terminal block assembly is electrically connected to the housing by screws. Using screws to fix the E-pole terminal on the metal housing 3 also serves as a grounding function, simplifying the installation steps and reducing the assembly of parts. As Figure 3 shown, at the bottom position of the housing 3 facing the insertion slot 35, there is a long strip-shaped raised step 34. The raised step 34 divides the first conductive cavity 311 and the second conductive cavity 312. There is a ground connection slot 341 on the raised step 34 for connecting with the ground pole insert 914 of the adapter 9, and it serves as a grounding and limiting function.

[0042] As Figure 11 shown, at least one end in the long side direction of the housing 3 is provided with an installation opening. The L-pole conductive sheet assembly 7 and the N-pole conductive sheet assembly 6 are inserted into the housing 3 through the installation opening. The power rail is provided with an installation sealing assembly for closing the installation opening. The decorative part 1 and the mounting bracket 2 form the installation sealing assembly. The L-pole conductive sheet assembly 7 and the N-pole conductive sheet assembly 6 are inserted into the first conductive cavity 311 and the second conductive cavity 312 from one end of the housing 3, and the installation sealing assembly seals the installation opening. Of course, as other embodiments, the installation sealing assembly can also be an integral structure or assembled by three or more components.

[0043] As Figure 9 、 10 shown, the first cover plate 5 is arranged at the bottom of the terminal block assembly 4. The first cover plate 5 can be used to shield the terminal block assembly 4 (L-pole terminal, N-pole terminal and E-pole terminal). Open the first cover plate 5 and connect the conductors of the external power supply to the L-pole terminal, N-pole terminal and E-pole terminal.

[0044] Preferably, the terminal block assembly 4 is also installed in the housing 3. The terminal block assembly 4 is inserted into the housing 3 through the installation opening at one end of the housing 3. The screw 8 connects the E-pole terminal and the housing 3. The screw 8 can simultaneously serve as a grounding function and fix the terminal block assembly 4 to the housing 3. Of course, as other embodiments, the terminal block assembly 4 and the housing 3 can also be provided with other limiting and fixing structures.

[0045] A preferred method is that the top of the terminal block assembly 4 is provided with a long strip-shaped guiding protrusion. When the terminal block assembly 4 is inserted into the housing 3 through the installation opening, the guiding protrusion slides into the insertion slot 35 correspondingly, serving as a guiding function for the installation of the terminal block assembly 4 and simultaneously serving as a shielding function for the insertion slot 35. At the bottom side of the housing 3, there are notches corresponding to the L-pole terminal, N-pole terminal and E-pole terminal and corresponding to the first cover plate 5. The first cover plate 5 is connected to the terminal block assembly 4 to shield the L-pole terminal, N-pole terminal and E-pole terminal.

[0046] As shown in Figure 6 , 7 Figure 1 is a power rail according to this embodiment. The decorative member 1 and the mounting bracket 2 form a mounting and sealing assembly, which is provided at both ends of the housing 3. One mounting and sealing assembly is provided at each end of the housing 3. Among them, at one end where the terminal block assembly 4 is assembled, the mounting and sealing assembly limits the terminal block assembly 4. At the end where the terminal block assembly 4 is not installed, the mounting and sealing assembly limits the L - pole conductive sheet assembly 7 and the N - pole conductive sheet assembly 6. The mounting bracket 2 is at least partially inserted into the mounting opening to limit the L - pole conductive sheet assembly 7 and the N - pole conductive sheet assembly 6. The decorative member 1 is installed on the top of the mounting bracket 2 and is flush with the top of the housing 3, serving a decorative function. As another embodiment, the terminal block assembly 4 can also serve as a mounting and sealing assembly, simultaneously functioning to connect wires and seal the mounting opening at at least one end of the housing 3.

[0047] As shown in Figure 4 , 5 Figure 2 shows an embodiment of the L - pole conductive sheet assembly 7. The structure of the N - pole conductive sheet assembly 6 is similar to that of the L - pole conductive sheet assembly 7. The L - pole conductive sheet assembly 7 and the N - pole conductive sheet assembly 6 each include: an insulating bracket 71, an elastic member 72, a dust - proof door 73, and a conductive sheet 74. The insulating bracket 71 includes a copper part mounting groove 711 at the bottom and a dust - proof door mounting groove 712 at the top. Both the copper part mounting groove 711 and the dust - proof door mounting groove 712 are provided with openings facing the middle of the hollow cavity 33. The conductive sheet 74 is installed in the copper part mounting groove 711, and the elastic member 72 and the dust - proof door 73 are installed in the dust - proof door mounting groove 712. The elastic members 72 of the L - pole conductive sheet assembly 7 and the N - pole conductive sheet assembly 6 drive the corresponding dust - proof doors 73 to slide towards each other to close the insertion slot 35.

[0048] As shown in Figure 8 Figure 3, a guiding and limiting structure is provided between the inner side wall of the conductive cavity and the outer side wall of the insulating bracket 71. The guiding and limiting structure is a conductive component limiting groove 32 provided on the inner side wall of the conductive cavity along the installation direction of the L - pole conductive sheet assembly 7 and the N - pole conductive sheet assembly 6, and a guiding and limiting rib 713 provided on the outer side wall of the insulating bracket 71. The guiding and limiting rib 713 is fitted into the conductive component limiting groove 32 to limit and fix the conductive sheet assembly.

[0049] Preferably, the guiding and limiting rib 713 is provided on the outer side of the connection between the copper part mounting groove 711 and the dust - proof door mounting groove 712. Of course, as another embodiment, the guiding and limiting structure can also be a limiting rib provided on the inner side wall of the conductive cavity and a limiting groove provided on the outer side wall of the insulating bracket 71. The guiding and limiting rib can be an entire long - strip rib or a plurality of small - strip ribs arranged at intervals; the insulating bracket 71 can be a whole piece or assembled in segments;

[0050] The conductive sheet 74 includes two clamping sheets 741 arranged oppositely, and a fixing sheet 742 connected between the two clamping sheets. The fixing sheet 742 is fixedly connected to the copper part mounting groove 711. The middle parts of the two clamping sheets 741 bulge and bend towards each other to form a clamping gap.

[0051] As Figure 5 shown, the dust-proof door 73 includes a plurality of sub-dust-proof doors 710 arranged side by side, and a plurality of elastic members 72 are respectively connected to the plurality of sub-dust-proof doors 710. Preferably, a linkage structure is provided between adjacent sub-dust-proof doors 710. The linkage structure includes a groove 731 and a protrusion 732; the groove 731 and the protrusion 732 are respectively arranged on both sides of each sub-dust-proof door 710; the protrusion 732 of the sub-dust-proof door 710 is arranged in the groove 731 of the adjacent sub-dust-proof door 710, and one sub-dust-proof door 710 can be linked with the adjacent sub-dust-proof door 710 through the groove 731 and the protrusion 732. One implementation method is the synchronous movement between the sub-dust-proof doors 710, and the groove 731 and the protrusion 732 are connected in an interference fit. Preferably, another method is that when the adapter 9 is inserted into the track to draw power, when the sub-dust-proof door 710 driven by the adapter 9 drives the adjacent sub-dust-proof door 710, the sliding distance of the adjacent linked sub-dust-proof door 710 along the retreat direction is less than the sliding distance of the sub-dust-proof door 710 driven by the adapter 9. For example, in the moving direction of the sub-dust-proof door 710, the width of the protrusion 732 is less than the width of the groove 731, that is, there is a linkage gap between the protrusion 732 and the groove 731. This can prevent all the sub-dust-proof doors 710 from being fully opened when the adapter 9 is inserted, or generating a huge resistance to prevent the insertion of the adapter 9. Thus, when a sub-dust-proof door 710 is driven by the adapter 9, it needs to move the distance of the linkage gap before driving the adjacent sub-dust-proof door 710 to move. With the setting of a suitable linkage gap, the number of adjacent linked sub-dust-proof doors 710 can be controlled within a small range, and only the dust-proof doors in the area covered by the adapter 9 will be appropriately retracted, so that the adapter 9 itself can be used to shield the insertion slot 35 area of the opened sub-dust-proof door 710, blocking the entry of dust, oil stains and other objects, thereby protecting the cleanliness of the components inside the track socket.

[0052] Furthermore, the adapter 9 and the power track in this embodiment also have an anti-misconnection function to prevent the L / N polarity on the adapter from being reversely connected to the L / N polarity on the power track.

[0053] As Figure 2In the illustrated embodiment, the adapter 9 includes a conductive sheet connection portion 91 and a socket body 92, and the conductive sheet connection portion 91 is connected to the socket body 92; an L-pole insert 913, an N-pole insert 912, and a ground-pole insert 914 are provided in the conductive sheet connection portion 91. The ground-pole insert 914 extends from the bottom of the conductive sheet connection portion 91 and contacts the ground-pole connection groove 341 on the raised step 34 of the power rail, thereby achieving grounding. The L-pole insert 913 and the N-pole insert 912 are symmetrically arranged on both sides of the conductive sheet connection portion 91 in a rotatable manner and can be rotated into and out of the conductive sheet connection portion 91. The conductive sheet connection portion 91 has a plate-like structure. Figure 2 As a cross-sectional view in the width direction thereof, when the adapter 9 is not inserted into the power rail, the L-pole insert 913 and the N-pole insert 912 are located inside the conductive sheet connection portion 91 and are respectively located on both sides of the ground-pole insert 914. When the conductive sheet connection portion 91 of the adapter 9 is inserted into the insertion slot 35 on the housing 3, when the rotating portion on the adapter 9 is rotated counterclockwise or clockwise by 90°, the L-pole insert 913 and the N-pole insert 912 are driven to rotate by 90° and extend out from the inside of the conductive sheet connection portion 91. At this time, the N-pole and L-pole inserts are unfolded and are respectively electrically connected to the conductive sheet of the N-pole conductive sheet assembly 6 and the conductive sheet of the L-pole conductive sheet assembly 7.

[0054] Preferably, an anti-fooling convex block 911 that rotates with the L-pole insert 913 or the N-pole insert 912 is provided in the conductive sheet connection portion 91. For example, the anti-fooling convex block 911 rotates with the L-pole insert 913, and the N-pole insert 912 is not provided with an anti-fooling convex block 911. Correspondingly, the two sides inside the insertion slot 35 are asymmetrically distributed, and an anti-fooling groove 31 is provided only on one side, that is, one side contains the anti-fooling groove 31 for cooperating with the anti-fooling convex block 911 of the adapter 9; the other side does not contain the anti-fooling groove 31 to fix the insertion direction of the adapter 9.

[0055] In this way, when the conductive sheet connection portion 91 of the adapter 9 is inserted into the insertion slot 35 on the housing 3, it can only be rotated in one direction. The anti-fooling convex block 911 that rotates with the L-pole insert 913 is fitted into the anti-fooling groove 31. The L-pole insert 913 is inserted into the conductive sheet of the L-pole conductive sheet assembly 7, and the N-pole insert 912 is inserted into the conductive sheet of the N-pole conductive sheet assembly 6. If the adapter 9 is rotated in the wrong direction, since the anti-fooling groove 31 is not provided on the other side inside the insertion slot 35, the L-pole insert 913 and the N-pole insert 912 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 913 and the conductive sheet of the N-pole conductive sheet assembly 6, and the connection between the N-pole insert 912 and the conductive sheet of the L-pole conductive sheet assembly 7, ensuring electrical safety.

[0056] The anti-fooling groove 31 of this embodiment is located inside the insertion groove 35, and the anti-fooling bump 911 is located inside the conductive sheet connection part 91 of the adapter 9. It rotates with the L-pole insert 913 or the N-pole insert 912. 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.

[0057] Adopting the technical solution of the embodiment has the following beneficial effects compared with the prior art:

[0058] (1) The present utility model provides a power rail, which adopts the design of an integrated metal shell, is not easy to deform, and is simple and convenient; grounding with the metal shell reduces the use of parts and is easy to assemble, reducing the assembly cost.

[0059] (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.

[0060] (3) The shell of the power rail provided by the present utility model adopts the design of a special anti-fooling groove, which can be combined with the anti-fooling bump in the conductive sheet connection part of the adapter, easily solving the problem of incorrect polarity insertion of the adapter.
