Detailed implementation manners

[0029] The following further elaborates on the present application in conjunction with the Figures 1 - 7 description of the accompanying drawings. Embodiment 1:

[0030] The embodiment of the present application discloses an orbital socket.

[0031] Referring to Figure 1 and Figure 2 , the orbital socket may include one or more adapters 200 and a power rail 100. The adapter 200 can be installed on the power rail 100 via the rail opening 3 on the power rail 100. The rail opening 3 of the power rail 100 can guide the adapter 200 to slide, so that the position of the adapter 200 can be adjusted flexibly. It can be understood that although Figure 1 only one adapter 200 is shown, the number of adapters 200 is not limited to one, and can be two or three or more, for example. When multiple adapters 200 are installed on the power rail 100, the positions of the multiple adapters 200 can be adjusted independently of each other.

[0032] Referring to Figure 2 and Figure 3, the power rail 100 includes a rail housing 101, a conductive conductor 103, a terminal 104, an end cap 102, and a protection door 105. Among them, the rail housing 101 serves as the outer shell of the power rail 100. The rail housing 101 includes an outer housing 1 and an inner housing 2 that are independent of each other, and the outer housing 1 and the inner housing 2 are snap-connected through a connecting device 5. The outer housing 1 serves as the outer shell of the power rail 100, and its material can be aluminum profile or insulating engineering plastic, which plays a protective role; the inner housing 2 serves as an installation base, and its material can be insulating engineering plastic for installing the conductive conductor 103. The outer housing 1 made of metal has higher strength and hardness, which is beneficial to protecting other components inside the power rail 100; the inner housing 2 made of plastic has better insulation performance, which is convenient for installing the conductive conductor 103 in the rail cavity and improves the safety of using the power rail 100.

[0033] Referring to Figure 2 and Figure 3 , the outer housing 1 includes a cross plate 11 and longitudinal plates 12 arranged on both sides of the cross plate 11. The two longitudinal plates 12 are on the same side of the cross plate 11, and the two longitudinal plates 12 are perpendicular to the cross plate 11. A rail opening 3 is formed in the cross plate 11 along its own length direction, and the rail opening 3 penetrates both sides of the cross plate 11 in the thickness direction. The overall cross-section of the outer housing 1 formed by the cross plate 11 and the two longitudinal plates 12 is in an n shape.

[0034] A conductor cavity 4 is formed in the inner housing 2 along its own length direction, and the conductor cavity 4 penetrates both ends of the cross plate 11 in the length direction. When the inner housing 2 is installed on the outer housing 1 through the connecting device 5, one side of the conductor cavity 4 facing the rail opening 3 penetrates the inner housing 2 and is connected to the rail opening 3. The conductor cavity 4 is divided into a live wire cavity, a neutral wire cavity, and a ground wire cavity. The ground wire cavity faces the rail opening 3 on the cross plate 11, and the live wire cavity and the neutral wire cavity are respectively arranged on both sides of the ground wire cavity and are symmetrically arranged with respect to the ground wire cavity. The lateral openings of the live wire cavity and the neutral wire cavity face the direction of the ground wire cavity and are connected to the ground wire cavity.

[0035] Referring to Figure 2 and Figure 3 , a plurality of anti-shrinkage grooves 9 are formed in the inner housing 2. The six anti-shrinkage grooves 9 are divided into two groups corresponding to the two outer side walls in the width direction of the inner housing 2, and the three anti-shrinkage grooves 9 in the same group are arranged parallel to each other. The anti-shrinkage grooves 9 are arranged on the two outer side walls of the inner housing 2 to reduce the wall thickness on both sides of the inner housing 2, which is convenient for the overall extrusion molding of the inner housing 2, improves the problem of structural deformation of the inner housing 2 caused by the too thick wall thickness of the inner housing 2 during the extrusion process of the inner housing 2, and prevents the outer wall of the inner housing 2 from collapsing.

[0036] The conductive conductor 103 is installed in the conductor cavity 4, and the conductive conductor 103 is set to be the same length as the conductor cavity 4. The number of the conductive conductors 103 is set to three, namely the live wire conductive conductor 103, the neutral wire conductive conductor 103, and the ground wire conductive conductor 103. The live wire conductive conductor 103 is installed in the live wire cavity, the neutral wire conductive conductor 103 is installed in the neutral wire cavity, and the ground wire conductive conductor 103 is installed in the ground wire cavity.

[0037] The number of the wiring terminals 104 is set to one or two. Referring to Figure 2 and Figure 3 , in the embodiment of the present application, the number of the wiring terminals 104 is described as one. The wiring terminal 104 is fixedly installed at one end of the inner housing 2 in the length direction through a screw, and the overall structure formed by the wiring terminal 104 and the inner housing 2 is set to be the same length as the outer housing 1, that is, the outer housing 1 completely covers the wiring terminal 104 and the inner housing 2. One end of the wiring terminal 104 connected to the inner housing 2 extends into the conductor cavity 4, and the terminal conductors of the wiring terminal 104 are respectively connected to the three conductive conductors 103. The other ends of the terminal conductors of the wiring terminal 104 are respectively connected to the corresponding power supply lines, so as to realize the power connection of the power track 100.

[0038] The number of the end caps 102 is set to two. The two end caps 102 are rectangular plates, and their materials are generally the same as those of the outer housing 1. The two end caps 102 are installed at both ends of the outer housing 1 in the length direction through screws. One end of the inner housing 2 away from the wiring terminal 104 abuts against one of the end caps 102, and one end of the wiring terminal 104 away from the inner housing 2 abuts against the other end cap 102.

[0039] Referring to Figure 2 and Figure 3 , the outer housing 1 and the inner housing 2 are connected by a connecting device 5, and the number of the connecting devices 5 is set to two. The two connecting devices 5 cooperate with each other to limit the outer housing 1 and the inner housing 2 in the width direction and the thickness direction of the track housing 101, so as to realize the stable connection between the outer housing 1 and the inner housing 2.

[0040] The connecting device 5 includes a first clamping component 51 and a second clamping component 52. The first clamping component 51 is integrally arranged on the inner side of the outer housing 1, and the second clamping component 52 is integrally arranged on the outer side of the inner housing 2.

[0041] Referring to Figure 2 and Figure 3 , the first clamping component 51 includes a first bending plate 511 and a first limiting plate 515. The first bending plate 511 is integrally formed on the cross plate 11, and its cross-sectional shape is L-shaped and is distributed along the length direction of the cross plate 11. A first clamping cavity 512 is formed between the first bending plate 511 and the cross plate 11, and the opening of the first clamping cavity 512 faces away from the track opening 3 and towards its adjacent longitudinal plate 12.

[0042] Refer to Figure 2 and Figure 3 As shown in FIGS.

[0043] Refer to Figure 2 and Figure 3 When the outer housing 1 is snap - connected to the inner housing 2, the first bent plate 511 is inserted into the second snap - connection cavity 514 along the bending part in the width direction of the track housing 101. At the same time, the second bent plate 513 is inserted into the first snap - connection cavity 512 along the bending part in the width direction of the track housing 101. In this way, the connection between the inner housing 2 and the outer housing 1 is limited in the two thickness directions of the track housing 101 and in one width direction. The first snap - connection assembly 51 of the other connection device 5 is symmetrically arranged about the axis in the width direction of the outer housing 1, and the second snap - connection assembly 52 of the other connection device 5 is symmetrically arranged about the axis in the width direction of the inner housing 2. In this way, the other connection device 5 realizes the limitation of the connection between the inner housing 2 and the outer housing 1 in the two thickness directions of the track housing 101 and in the other width direction. The two connection devices 5 cooperate with each other to jointly limit the inner housing 2 and the outer housing 1 in the width direction and the thickness direction, so that the inner housing 2 and the outer housing 1 can only be inserted and connected in the length direction of the track housing 101.

[0044] The first limiting plate 515 is a bent plate, which is integrally formed at the bending part of the first bent plate 511 and is distributed along the length direction of the cross - plate 11. The connecting end of the first limiting plate 515 is flush and parallel to the bending end of the first bent plate 511, that is, the connecting end of the first limiting plate 515 and the bending end of the first bent plate 511 are symmetrically arranged with respect to the connecting end of the first bent plate 511. The bending end of the first limiting plate 515 is arranged on the side of the connecting end of the first limiting plate 515 away from the first bent plate 511, and the bending end of the first limiting plate 515 extends in the direction away from the cross - plate 11. A first right - angle cavity 516 is formed between the connecting end and the bending end of the first limiting plate 515, and the inner fire - wire shell of the inner housing 2 wrapping the fire - wire cavity is tightly installed on the cavity wall of the first right - angle cavity 516.

[0045] The first limiting plate 515 abuts against the inner housing 2, realizing the limitation between the inner housing 2 and the outer housing 1 in one direction of the thickness and one direction of the width of the track housing 101. The first limiting plate 515 of the other connecting device 5 is symmetrically arranged about the axis in the width direction of the outer housing 1. Then, the first limiting plate 515 of the other connecting device 5 realizes the limitation between the inner housing 2 and the outer housing 1 in the same direction of the thickness of the track housing 101 and the other direction of the width. The first limiting plates 515 of the two connecting devices 5 cooperate with each other to jointly limit the inner housing 2 and the outer housing 1 in two directions of the width and one direction of the thickness, improving the connection stability between the inner housing 2 and the outer housing 1.

[0046] Refer to Figure 2 and Figure 3 , a protective cavity 517 is formed between the connecting end of the first limiting plate 515 and the cross plate 11, and the opening of the protective cavity 517 faces the direction of the track opening 3. The protection door 105 is installed in the protective cavity 517 to block the track opening 3. When the adapter 200 is not inserted into the power track 100, the protection door 105 blocks the track opening 3 to prevent foreign objects from entering the track housing 101 through the track opening 3; when the adapter 200 is inserted into the power track 100, the adapter 200 causes the protection door 105 to release the block of the track opening 3 to facilitate the insertion of the adapter 200 into the power track 100 to draw power; after the adapter 200 is pulled out from the power track 100, the protection door 105 resumes blocking the track opening 3.

[0047] Refer to Figure 2 and Figure 3 , limiting convex ribs 6 are arranged along the length direction of the two longitudinal plates 12. The two limiting convex ribs 6 face each other. Screw cavities 10 are formed on the limiting convex ribs 6. Screws passing through the end cover 102 are threadedly connected to the screw cavities 10 on the same side of the two limiting convex ribs 6, realizing the fixed installation of the end cover 102 on the outer housing 1.

[0048] Refer to Figure 2 and Figure 3 , a second limiting plate 7 is integrally formed on the inner housing 2. The second limiting plate 7 extends along the length direction of the inner housing 2 and extends outward toward the longitudinal plate 12. A second right-angle cavity 8 is formed between the second limiting plate 7 and the outer wall of the inner housing 2. The limiting convex rib 6 fits and abuts against the cavity wall of the second right-angle cavity 8.

[0049] Refer to Figure 2 and Figure 3, the second limiting plate 7 and the inner housing 2 are respectively in abutment with the two outer walls of the limiting rib 6, realizing the limitation of the inner housing 2 and the outer housing 1 in one direction of the thickness and one direction of the width of the track housing 101. Another second limiting plate 7 is symmetrically arranged with respect to the width direction of the inner housing 2, so that the other second limiting plate 7 realizes the limitation of the inner housing 2 and the outer housing 1 in the same direction of the thickness of the track housing 101 and the limitation in the other direction of the width. The two second limiting plates 7 cooperate with each other to jointly limit the inner housing 2 and the outer housing 1 in the two width directions and one thickness direction, improving the connection stability between the inner housing 2 and the outer housing 1.

[0050] Refer to Figure 3 and Figure 4 , at the ends of the two longitudinal plates 12 of the outer housing 1 away from the transverse plate 11, first backplate engaging ribs 13 are respectively formed. The first backplate engaging ribs 13 are distributed along the length direction of the longitudinal plates 12, and the first backplate engaging ribs 13 on the two longitudinal plates 12 are arranged facing each other. On both sides of the mounting backplate 106, a plurality of first backplate engaging blocks 14 are respectively formed along its own length direction. Refer to Figure 4 , the four first backplate engaging blocks 14 are divided into two groups and are respectively arranged on both sides of the mounting backplate 106. The two first backplate engaging blocks 14 in the same group are in engaging cooperation with the first backplate engaging ribs 13, so that the mounting backplate 106 is fixedly mounted on the outer housing 1.

[0051] Refer to Figure 3 and Figure 4 , on the outer peripheral wall of the inner housing 2, a second backplate engaging rib 15 and a third backplate engaging rib 16 are formed. Both the second backplate engaging rib 15 and the third backplate engaging rib 16 extend along the length direction of the inner housing 2. The second backplate engaging rib 15 and the third backplate engaging rib 16 are perpendicularly arranged. The second backplate engaging rib 15 is arranged on the outer side in the width direction of the inner housing 2, and its protruding direction is the same as that of the second limiting plate 7. The anti-shrinkage groove 9 is arranged between the second limiting plate 7 and the second backplate engaging rib 15. Another second backplate engaging rib 15 is symmetrically arranged with respect to the center line in the width direction of the inner housing 2.

[0052] The third backplate engaging rib 16 is arranged on the outer side of the inner housing 2 in the thickness direction away from the transverse plate 11, and its protruding direction is along the direction away from the transverse plate 11. Another third backplate engaging rib 16 is symmetrically arranged with respect to the center line in the width direction of the inner housing 2.

[0053] Refer to Figure 4 and Figure 5, In another implementable way, a clamping rib cavity that cooperates with the second backplane clamping rib 15 and the third backplane clamping rib 16 is formed on the installation backplane 106. The second backplane clamping rib 15 and the third backplane clamping rib 16 are clamped and matched with the clamping rib cavity to realize the clamping installation of the track housing 101 and the installation backplane 106. During the installation process of the power track 100, first, fasteners such as screws or expansion bolts are used to fixedly install the installation backplane 106 on the installation surface, and then the power track 100 is clamped and installed with the installation backplane 106, so as to realize the installation of the power track 100 on the installation surface. It should be noted that the installation surface can be a wall surface, a surface of a cabinet, etc., or a curved surface with a large curvature.

[0054] The implementation principle of Embodiment 1 is as follows: By separately setting the track housing 101 into the inner housing 2 and the outer housing 1, when the component structure of the track housing 101 changes, most of the adjustments only need to be made to the outer housing 1, and the inner housing 2 and the structures inside the inner housing 2 can continue to be used, or only the inner housing 2 needs to be adjusted, and the outer housing 1 and the structures on the outer housing 1 can continue to be used. Therefore, the split track housing 101 is beneficial to reducing the production cost of the power track 100 and improving the competitiveness of the power track 100 in the industry. Embodiment 2:

[0055] The structure of the power track 100 according to the second embodiment of the present application is basically the same as the structure of the power track 100 according to the first embodiment of the present application described above. The following mainly describes the differences between the two.

[0056] Referring to Figure 6 and Figure 7 , the power track 100 according to the second embodiment of the present application is an embedded power track 100, that is, the power track 100 of the second embodiment is integrally embedded and installed in the installation surface.

[0057] The two longitudinal plates 12 are arranged in the width direction of the transverse plate 11, and there is still a certain distance formed at both ends of the longitudinal plates 12 in the width direction of the transverse plate 11. That is to say, the distance between the two longitudinal plates 12 is less than the width of the transverse plate 11.

[0058] The cross-section of the installation backplane 106 is U-shaped, and it extends along the length direction of the track housing 101. The ends of the installation backplane 106 face each other to form an embedded clamping rib 17. When the power track 100 is installed on the installation surface, first, the installation backplane 106 is embedded and installed in the power track 100 installation groove opened on the installation surface by using screws or adhesive stickers, and then the track housing 101 is clamped and connected with the installation backplane 106. At this time, the transverse plate 11 is flush with the installation surface, and the installation surface completely covers the other component structures of the power track 100, and the longitudinal plates 12 no longer act as the protective housing of the power track 100 exposed outside.

[0059] The embedded clamping edge 17 is clamped and installed on the limiting convex edge 6 to realize the clamping fit between the mounting back plate 106 and the outer housing 1. The inner housing 2 is clamped and installed on the outer housing 1, and finally the embedded installation of the power rail 100 on the installation surface is realized.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
