Description

Technical Field

[0001] This application relates to the technical field of track sockets, and particularly to the installation of power rails on mounting surfaces, specifically to an embedded power rail assembly structure. 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, tables, or other mounting surfaces. The power track has openings; the adapter's power-drawing part is inserted into the power track through these openings and comes into contact with the conductive conductors within the track, thus allowing the adapter to draw power from the track.

[0003] When the power rail is installed on the mounting surface in an embedded manner, a rail cavity is first opened on the mounting surface, and then the power rail is embedded in the rail cavity. At this time, the panel with the rail opening of the power rail is flush with the mounting surface.

[0004] Regarding the aforementioned technologies, the inventors discovered that after the power rail is installed on the mounting surface, due to the gap between the power rail and the rail cavity, the power rail will shake inside the rail cavity. When pulling the adapter installed on the power rail, or pulling the plug installed on the adapter, the power rail is easily pulled out of the rail cavity, resulting in an unstable installation of the power rail on the mounting surface. Utility Model Content

[0005] This application was made in response to the deficiencies of the prior art. The purpose of this application is to provide an embedded electric rail assembly installation structure, in which the electric rail can be stably installed on the mounting surface, thereby improving the stability of the electric rail installation on the mounting surface.

[0006] The embedded electric rail assembly installation structure provided in this application adopts the following technical solution:

[0007] An embedded power rail assembly structure includes a power rail, a rail body, and two socket plates disposed on the rail body. A conductor cavity is formed within the rail body, and a rail opening is formed between the two socket plates, the rail opening communicating with the conductor cavity. A base plate is used to mount a pressure plate. The pressure plate is fitted onto the base plate, and a rail cavity is formed at the connection between the base plate and the pressure plate. The rail body is installed within the rail cavity. An insertion cavity is formed on the pressure plate, communicating with the rail cavity, and the two socket plates are placed within the insertion cavity.

[0008] Optionally, the track cavity includes at least a first track half-cavity formed on the pressure plate, the first track half-cavity communicating with the insertion cavity, the first track half-cavity penetrating the side of the pressure plate near the base plate, and the electric track body being at least partially installed in the first track half-cavity.

[0009] Optionally, the track cavity includes at least a second track half-cavity formed on the pressure plate, the second track half-cavity being adapted to and connected to the first track half-cavity, the second track half-cavity penetrating the side of the substrate near the pressure plate, and the power track body being at least partially installed in the second track half-cavity.

[0010] Optionally, the chamber depth of the first track half cavity is 1mm, 2mm, 5mm, 8mm, 14mm or 17mm, and the chamber depth of the second track half cavity is adapted to the chamber depth of the first track half cavity.

[0011] Optionally, the track cavity is formed on the substrate, and the track cavity extends through the side of the substrate near the pressure plate.

[0012] Optionally, a stepped surface is formed between the track cavity and the insertion cavity, and the stepped surface is in contact with the side of the track body where the insertion plate is disposed.

[0013] Optionally, the two walls of the insertion cavity abut against the opposite sides of the two insertion plates.

[0014] Optionally, the depth of the insertion cavity is 4 mm.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] By attaching a pressure plate to the surface of the substrate and creating a track cavity between the pressure plate and the substrate, the power rail is placed inside the track cavity. The pressure plate presses and fixes the power rail to the substrate, which effectively improves the stability of the power rail fixed installation on the mounting surface and reduces the risk of the power rail being pulled out of the track cavity.

[0017] By dividing the track cavity into a first track half-cavity formed on the pressure plate and a second track half-cavity formed on the base plate, the main body of the track is placed in the first track half-cavity and the other part is placed in the second track half-cavity. The first track half-cavity and the second track half-cavity together limit the track body, which improves the problem of the electric track easily shaking after it is installed on the mounting surface.

[0023] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that these specific descriptions are only for teaching those skilled in the art how to implement this application, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.

[0024] To enable those skilled in the art to better understand the present application, the following will be described in conjunction with the appendix to the specification. Figure 1-4 The technical solutions in the embodiments of this application will be clearly and completely described.

[0025] The embedded electric rail assembly installation structure according to the first embodiment of this application:

[0026] Reference Figure 1 and Figure 2 This application provides an embedded power rail 3 assembly structure. It includes a base plate 1, a pressure plate 2 mounted on the base plate 1, and a power rail 3 mounted between the base plate 1 and the pressure plate 2.

[0027] Reference Figure 1 and Figure 2 The electric track 3 includes a track body 31 and an insert plate 32 integrally formed on the track body 31.

[0028] Reference Figure 1 and Figure 2The track body 31 is constructed in a rectangular shape, comprising a track housing 311, an insulating support 312, a conductive conductor 313, and a terminal block 314. The insulating support 312 may be made of insulating plastic, with an opening on its top side in the thickness direction. The conductive conductor 313 is a strip-shaped structure with a dimension larger in its primary extension direction than in other directions, extending along its length, with its length significantly greater than its width and thickness. The conductive conductor 313 is installed within the insulating support 312 and is of equal length to the insulating support 312. In this embodiment, two conductive conductors 313 are provided, namely a live wire conductive conductor 313 and a neutral wire conductive conductor 313, and the two conductive conductors 313 are positioned on opposite sides of the opening of the insulating support 312. In another possible implementation, three conductive conductors 313 may be provided, with the additional conductive conductor 313 being a ground wire conductive conductor 313, installed at the bottom of the opening of the insulating support 312.

[0029] Reference Figure 1 and Figure 2 The terminal block 314 is snapped onto one end of the insulating bracket 312 along its length. The wiring conductors inside the terminal block 314 are connected to the conductive conductors 313 respectively. It can be understood that the number of wiring conductors inside the terminal block 314 is matched with the number of conductive conductors 313, that is, one wiring conductor corresponds to one conductive conductor 313.

[0030] Reference Figure 1 and Figure 2 The track housing 311 can be made of an alloy metal such as aluminum alloy. The track housing 311 is a hollow rectangular tube with an internal cavity that serves as a conductor cavity 33. End caps 315 are fixedly installed at both ends of the track housing 311 by screws, and the end caps 315 are used to block the two ends of the cavity of the track housing 311. The insulating bracket 312, the conductive conductor 313, and the terminal block 314 are placed inside the conductor cavity 33. Screws pass through the track housing 311 and are threadedly connected to the insulating bracket 312, thereby fixing the terminal block 314 inside the conductor cavity 33, and consequently fixing the conductive conductor 313 and the insulation inside the conductor cavity 33.

[0031] Reference Figure 1 and Figure 2 The socket plate 32 is integrally formed at the center of the top surface of the track housing 311, extends along the length of the track housing 311 and is set to the same length as the track housing 311. There are two socket plates 32, which are arranged parallel to each other. A socket cavity 5 is formed between the two socket plates 32, and the socket cavity 5 penetrates the track housing 311 and communicates with the conductor cavity 33.

[0032] Reference Figure 1 and Figure 2The base plate 1 is used to mount the pressure plate 2 and part of the power track 3. It can be mounted on a wall or tabletop. A second track cavity 42 is formed on the side of the base plate 1 facing the pressure plate 2. The second track cavity 42 penetrates the side of the base plate 1 facing the pressure plate 2, that is, the second track cavity 42 is a recessed structure on the base plate 1. The track body 31 is partially installed in the second track cavity 42, and the outer wall of the track body 31 is tightly fitted with the five cavity walls of the second track cavity 42.

[0033] The pressure plate 2 can be attached to the surface of the substrate 1 by screws or adhesive, and can be a slab structure such as a ceramic tile or countertop. A first track cavity 41 is formed on the side of the pressure plate 2 facing the substrate 1, penetrating the side of the pressure plate 2 facing the substrate 1; that is, the first track cavity 41 has a recessed structure on the pressure plate 2. The track body 31 is partially installed inside the first track cavity 41, and the outer wall of the track body 31 is tightly fitted to the five cavity walls of the first track cavity 41.

[0034] It is understood that the cross-section of the first track half-cavity 41 along the thickness direction of the pressure plate 2 is the same as the cross-section of the second track half-cavity 42 along the thickness direction of the substrate 1. When the pressure plate 2 is fixedly installed on the substrate 1, the first track half-cavity 41 and the second track half-cavity 42 are combined to form the track cavity 4. The track body 31 is installed in the track cavity 4, and the outer wall of the track body 31 is tightly fitted with the inner wall of the track cavity 4. In this configuration, the pressure plate 2 presses and fixes the electric track 3 to the substrate 1, while the track cavity 4 fixes and limits the electric track 3, effectively improving the stability of the electric track 3 fixedly installed on the mounting surface and reducing the risk of the electric track 3 being pulled out of the track cavity 4 by the user.

[0035] Reference Figure 1 and Figure 2The depth of the track cavity 4 is the same as the thickness of the track body 31; that is, the sum of the depth of the first track half-cavity 41 and the depth of the second track half-cavity 42 is exactly equal to the thickness of the track body 31. In the actual installation of the electric track 3, the depth of the first track half-cavity 41 is usually determined first based on the thickness of the pressure plate 2, and the depth of the second track half-cavity 42 is adapted to the depth of the first track half-cavity 41. The depth of the first track half-cavity 41 varies slightly depending on the thickness of the pressure plate 2. The thickness of the first track half-cavity 41 is usually the thickness of the pressure plate 2 minus 4mm. For example, for a 5mm pressure plate 2, the chamber depth of its first track cavity 41 is typically set to 1mm; for a 6mm pressure plate 2, the chamber depth of its first track cavity 41 is typically set to 2mm; for a 9mm pressure plate 2, the chamber depth of its first track cavity 41 is typically set to 5mm; for a 12mm pressure plate 2, the chamber depth of its first track cavity 41 is typically set to 8mm; for an 18mm pressure plate 2, the chamber depth of its first track cavity 41 is typically set to 14mm; and for a 21mm pressure plate 2, the chamber depth of its first track cavity 41 is typically set to 17mm.

[0036] Reference Figure 2 The pressure plate 2 also has an insertion cavity 5 on the side facing away from the base plate 1. The insertion cavity 5 is parallel to and of equal length to the first track half cavity 41, and is connected to the first track half cavity 41. When the track body 31 is installed in the track cavity 4, the two insertion plates 32 forming the track opening 34 are placed in the insertion cavity 5. The depth of the cavity of the insertion cavity 5 is adapted to the depth of the insertion plate 32 protruding from the track body 31, that is, the depth of the cavity of the insertion cavity 5 is the same as the depth of the insertion plate 32 protruding from the track body 31. Therefore, when the track body 31 is installed in the track cavity 4, the end of the insertion plate 32 facing away from the track body 31 is flush with the surface of the pressure plate 2 where the insertion cavity 5 is located. In this embodiment, the depth of the cavity of the insertion cavity 5 is set to 4mm, which corresponds to the 4mm subtracted from the pressure plate 2 when the thickness of the first track half cavity 41 is determined. That is, the sum of the depth of the insertion cavity 5 and the depth of the first track half cavity 41 is equal to the thickness of the pressure plate 2.

[0037] Reference Figure 2 A stepped surface 6 is formed between the first track half cavity 41 and the insertion cavity 5. The track body 31 is attached to the side of the stepped surface 6 where the insertion plate 32 is located. The stepped surface 6 limits the electric track 3 along the thickness direction, pressing the electric track 3 down and fixing it in the track cavity 4, improving the stability of the track body 31 installed in the track cavity 4, and reducing the risk of the electric track 3 detaching from the track cavity 4.

[0038] Furthermore, the two walls of the insertion cavity 5 are respectively pressed against the opposite sides of the two insertion plates 32, and the walls of the insertion cavity 5 limit the movement of the electric track 3 along its width direction, effectively reducing the installation gap between the insertion plates 32 and the insertion cavity 5, improving the stability of the electric track 3 installed in the insertion cavity 5, and reducing the shaking of the track body 31 in the track cavity 4. Moreover, there is no gap between the insertion plates 32 and the insertion cavity 5, so that only the pressure plate 2, the insertion plates 32, and the track opening 34 are visible on the surface of the pressure plate 2, resulting in a more aesthetically pleasing appearance after the electric track 3 is installed.

[0039] When installing the power rail 3 on the mounting surface, firstly, a first rail half-cavity 41 and a socket 5 are respectively opened on the pressure plate 2, and a second rail half-cavity 42 is opened on the base plate 1. Then, the power rail 3 is installed in the first rail half-cavity 41, with the socket plate 32 placed in the socket 5. Then, the pressure plate 2 is attached to and fixed to the base plate 1, with the portion of the rail body 31 protruding from the pressure plate 2 placed in the second rail half-cavity 42. Alternatively, the power rail 3 can be installed in the second rail half-cavity 42 first, and then the pressure plate 2 is attached to and fixed to the base plate 1. In this case, the portion of the rail body 31 protruding from the base plate 1 is placed in the first rail half-cavity 41, and the socket plate 32 is placed in the socket 5.

[0040] The implementation principle of the first embodiment of this application is as follows: by attaching and installing a pressure plate 2 on the surface of the substrate 1, the pressure plate 2 presses and fixes the power rail 3 on the substrate 1, the insertion cavity 5 limits the power rail 3 in the thickness direction, and the rail cavity 4 limits the power rail 3 in the width and length directions, which effectively improves the stability of the power rail 3 fixedly installed on the mounting surface and reduces the risk of the power rail 3 being pulled out from the rail cavity 4.

[0041] The embedded power rail 3 assembly structure according to the second embodiment of this application:

[0042] The embedded electric rail 3 assembly installation structure according to the second embodiment of this application is basically the same as the embedded electric rail 3 assembly installation structure according to the first embodiment of this application described above. The following mainly describes the differences between the two.

[0043] Reference Figure 3 The difference between the second embodiment and the first embodiment is that the track cavity 4 only includes the first track half cavity 41; the substrate 1 is a plane and does not have a second track half cavity 42.

[0044] Reference Figure 3The first track cavity 41 is a recessed groove completely formed on the pressure plate 2; the insertion cavity 5 is formed on the pressure plate 2 and is connected to the track cavity 4. The track body 31 is placed in the first track cavity 41, and the insertion plate 32 is placed in the insertion cavity 5. The outer wall of the track body 31 with the insertion plate 32 is in contact with the stepped surface 6 of the track cavity 4 connecting to the insertion cavity 5. The outer wall of the track body 31 facing away from the insertion plate 32 is flush with the surface of the pressure plate 2, and when the pressure plate 2 is installed on the base plate 1, this surface is in contact with and pressed tightly against the base plate 1.

[0045] When the electric track 3 is installed on the mounting surface, the track body 31 is first fixedly installed in the track cavity 4 on the pressure plate 2. At this time, the insertion plate 32 is placed in the insertion cavity 5. Finally, the pressure plate 2 is fixedly installed on the base plate 1.

[0046] The embedded electric rail 3 assembly installation structure according to the third embodiment of this application:

[0047] The embedded electric rail 3 assembly installation structure according to the third embodiment of this application is basically the same as the embedded electric rail 3 assembly installation structure according to the first embodiment of this application described above. The following mainly describes the differences between the two.

[0048] Reference Figure 4 The difference between the third embodiment of this application and the first embodiment is that the first track half cavity 41 is not opened on the pressure plate 2, the second track half cavity 42 is not opened on the substrate 1, and the track cavity 4 is directly opened on the substrate 1.

[0049] Reference Figure 4 The track cavity 4 is a recessed groove completely formed on the base plate 1; the insertion cavity 5 is formed on the pressure plate 2 and extends through the pressure plate 2. The track body 31 is placed in the first track half cavity 41, and the outer wall of the insertion plate 32 is flush with the surface of the base plate 1. The pressure plate 2 is mounted on the base plate 1, and the outer wall of the insertion plate 32 of the track body 31 is pressed tightly against the pressure plate 2, with the insertion plate 32 placed inside the insertion cavity 5.

[0050] When the electric track 3 is installed on the mounting surface, the track body 31 is first fixedly installed in the track cavity 4 on the base plate 1, and then the pressure plate 2 is fixedly installed on the base plate 1. At this time, the socket plate 32 is placed in the socket cavity 5.

[0051] 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 in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
