Description

Technical Field

[0001] This application relates to the technical field of track sockets, and in particular to an insulating bracket, an electric track, and a track socket. Background Technology

[0002] Track sockets are a new type of socket product, mainly consisting of a power track and an adapter. The adapter primarily comprises a power receiving section and a power supply section. The power receiving section has a retractable power receiving arm that extends from the receiving section and inserts into the power track to draw power. The power track, also known as a power rail, is typically installed on walls, tables, and baseboards. The power track includes a track housing, within which two corresponding track cavities are formed. Each track cavity contains an insulating support, and a conductive conductor is installed within the conductor cavity of the insulating support. The openings of the track cavities in the two track housings are positioned opposite each other, and the opening direction of each track cavity is the same as that of its own internal chamber.

[0003] When the adapter is inserted into the power rail to draw power, the power-drawing part of the adapter is placed between the two rail cavities. Then, the power-drawing arm extends from the power-drawing part, passes through the cavity opening of the conductor cavity, and enters the conductor cavity. The power-drawing arm contacts the conductive conductor, allowing the adapter to draw power from the power rail. The appliance plug is inserted into the socket in the base, making contact with the power-drawing part. The current in the power rail is transmitted to the appliance through the conductive conductor, the power-drawing arm, and the power supply part.

[0004] Regarding the aforementioned technologies, the inventors discovered that, due to the large opening of the insulating support chamber, dust can easily enter the interior of the power rail through the chamber opening, causing interference to the internal conductive conductors and reducing the conductivity and service life of the power rail. Utility Model Content

[0005] This application was made in response to the deficiencies of the prior art. One objective of this application is to provide an insulating bracket that can shield the chamber opening, reducing the problem of dust entering the power rail through the chamber opening and ensuring the conductivity and service life of the power rail. Another objective of this application is to provide a power rail including the aforementioned insulating bracket. A further objective of this application is to provide a rail socket including the aforementioned power rail with the insulating bracket.

[0006] To achieve the above objectives, the present application may adopt the following technical solutions.

[0007] This application provides an insulating support, comprising two opposing horizontal plates and a vertical plate connected to the same side of the two horizontal plates. A conductor cavity for inserting an adapter power-taking arm is formed between the two horizontal plates. A chamber opening is formed on the side of the conductor cavity opposite to the vertical plate. A safety door is provided on the side of the horizontal plate opposite to the vertical plate. The safety door is configured to block the chamber opening when the adapter power-taking arm is not inserted into the conductor cavity, and to open the chamber opening when the adapter is inserted into the insulating support.

[0008] Optionally, the safety door includes a rigid plate fixedly mounted on the horizontal plate and an elastic strip mounted on the side of the rigid plate facing the conductor cavity. Both the rigid plate and the elastic strip extend along the length of the horizontal plate, and the elastic strip can deform in a direction close to or away from the rigid plate.

[0009] Optionally, an elastic cavity is formed within the elastic strip.

[0010] Optionally, the elastic strip has at least one friction ridge on the side opposite to the rigid plate, and the friction ridge is located on the side of the elastic strip opposite to the conductor cavity.

[0011] Optionally, the number of safety doors is set to two, and the two safety doors are respectively installed on the two horizontal plates.

[0012] Optionally, a conductor mounting cavity for mounting a conductive conductor is provided on one side of the two cross plates facing each other, and the conductor mounting cavity is connected to the conductor cavity.

[0013] Optionally, the conductor mounting cavity is narrowed in the direction close to the conductor cavity.

[0014] Optionally, an extrusion process hole is provided at the bottom corner of the conductor mounting cavity away from the conductor cavity.

[0015] Optionally, one of the cross plates is fixed with at least one snap-fit ​​edge on the side opposite to the other cross plate, the snap-fit ​​edge being configured to snap into the track housing.

[0016] This application also provides an electric track, comprising a track housing, a terminal block fixed at one end of the track housing, an insulating support as described in any of the above technical solutions fixed within the track housing, and a conductive conductor installed within the insulating support, wherein the conductive conductor is electrically connected to the terminal block.

[0017] This application also provides a rail socket comprising at least one adapter and the power rail described in the above technical solutions.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] By installing safety doors at the opening of the insulating support track cavity, the safety doors block the cavity opening when the adapter is not inserted into the insulating support, and open the cavity opening when the adapter is inserted into the insulating support. This prevents dust from entering the interior of the electric rail through the cavity opening, reduces the interference of dust on the conductive conductors inside the insulating support, ensures the conductivity and service life of the electric rail, and improves the safety of electric rail use.

[0020] By creating an elastic cavity along its own axis on the elastic strip, the elastic cavity increases the contraction space of the elastic strip, giving it greater deformation capacity, thus avoiding the opening of the cavity and facilitating the insertion of the adapter's power-taking arm.

[0021] By setting multiple friction ridges on the outer wall of the elastic strip, when the adapter's power-taking arm is inserted, the power-taking arm first contacts the friction ridges on the elastic strip. Due to the frictional action of the friction ridges, the elastic strip is pushed to deform towards the conductor cavity, while simultaneously pushing the elastic strip back towards the rigid plate. The setting of the friction ridges transforms the surface contact between the elastic strip and the power-taking arm into a line contact, reducing the frictional force between the elastic strip and the power-taking arm, making the process of the power-taking arm entering or retracting from the conductor cavity smoother.

[0029] 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 intended to teach 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. In a specific embodiment of this application, the power track 200 is configured to have a ring shape. "Conductive conductor 104" refers to a conductor having a strip structure in which the dimension in its primary extension direction is greater than the dimensions in other directions; for example, in the following embodiments, the conductive conductor 104 extends along its length direction, and its length is much greater than its width and thickness.

[0030] The following is in conjunction with the instruction manual. Figure 1-4 The track socket according to an embodiment of this application will be described.

[0031] Reference Figure 1 The track socket may include one or more adapters 100 and a power track 200. The adapters 100 can be mounted on the power track 200 via adapter mounting cavities 105. It is understood that although only one adapter 100 is shown in the figure, the number of adapters 100 is not limited to one; for example, there may be two or more. When multiple adapters 100 are mounted on the power track 200, the positions of the multiple adapters 100 can be adjusted independently of each other.

[0032] Reference Figures 1-4 The electric track 200 includes a track housing 101, an insulating bracket 103, a conductive conductor 104, and a terminal block 102 mounted on the track housing 101.

[0033] Reference Figure 2 The track housing 101 can be made of an alloy metal such as aluminum alloy and coated with an oxide insulating layer. The track housing 101 is a hollow U-shape, and an adapter mounting cavity 105 is formed between the two long straight sections of the track housing 101. When the power rail 200 is installed on the mounting surface, the adapter mounting cavity 105 faces the user. Track cavities 106 are formed in each of the two long straight sections of the track housing 101 along their own length direction. A track cavity opening 107 is formed on the side of the two long straight sections of the track housing 101 that is close to each other. The track cavity opening 107 is connected to the track cavity 106, and the adapter mounting cavity 105 is connected to the track cavity opening 107.

[0034] Reference Figure 2 and Figure 3Two insulating supports 103 are provided, each installed in one of the two track cavities 106. The insulating supports 103 are fixed relative to the track housing 101. In this embodiment, the insulating supports 103 are made of insulating material such as plastic. The insulating supports 103 include two parallel horizontal plates 1 and a vertical plate 2 connected to the same side of the two horizontal plates 1 and perpendicular to both horizontal plates 1. A conductor cavity 3 is formed between the two horizontal plates 1, and a cavity opening 4 is formed on the side of the conductor cavity 3 facing away from the vertical plate 2.

[0035] Reference Figure 2 and Figure 3 One of the horizontal plates 1 has a snap-fit ​​ridge 8 integrally formed on the side opposite to the conductor cavity 3, extending along the length of the horizontal plate 1. Two snap-fit ​​ridges 8 are provided, located at opposite ends of the same horizontal plate 1 in the width direction. When the insulating bracket 103 is installed in the track cavity 106, the snap-fit ​​ridges 8, the horizontal plate 1 without snap-fit ​​ridges 8, and the vertical plate 2 are respectively pressed against the cavity wall of the track cavity 106. The snap-fit ​​ridges 8 improve the stability of the insulating bracket 103 during installation in the track cavity 106.

[0036] Reference Figure 2 and Figure 3 The two horizontal plates 1 of the insulating bracket 103 each have a conductor mounting cavity 6 formed on their end faces that form the conductor cavity 3. The conductor mounting cavity 6 extends along the length of the horizontal plate 1 and penetrates through the horizontal plate 1. The cross-section of the conductor mounting cavity 6 is approximately trapezoidal, that is, the conductor mounting cavity 6 is narrowed towards the conductor cavity 3. The conductive conductor 104 is inserted and installed in the conductor mounting cavity 6 along the length of the insulating bracket 103. The trapezoidal structure of the conductor mounting cavity 6 effectively fixes the conductive conductor 104 in the conductor mounting cavity 6, preventing the conductive conductor 104 from detaching from the conductor mounting cavity 6.

[0037] The conductor mounting cavity 6 has extrusion process holes 7 at its two bottom corners opposite to the conductor cavity 3, along the axial direction of the conductor mounting cavity 6. By providing the extrusion process holes 7, the extrusion of the insulating support 103 is facilitated during the extrusion production process, solving the problem of the inability to manufacture the bottom corners of the trapezoidal conductor mounting cavity 6. It also facilitates the processing and manufacturing of the extrusion die for the insulating support 103.

[0038] Reference Figure 2 , Figure 3 and Figure 4 A safety door 5 is integrally provided on the side of the horizontal plate 1 opposite to the vertical plate 2. In this embodiment, the number of safety doors 5 is set to four, and they are arranged in pairs opposite each other, and are respectively fixed on the four horizontal plates 1 of the two insulating brackets 103. When the insulating brackets 103 are installed in the track cavity 106, the safety door 5 is just positioned at the track cavity opening 107.

[0039] Reference Figure 3 and Figure 4 The structure of the safety door 5 will be further explained below using two oppositely arranged safety doors 5 on an insulating bracket 103.

[0040] Reference Figure 3 and Figure 4 The safety door 5 includes a rigid plate 51 and an elastic strip 52. The rigid plate 51 is integrally disposed on the side of the horizontal plate 1 opposite to the vertical plate 2. The rigid plate 51 is parallel to the horizontal plate 1, extends along the length of the horizontal plate 1, and is of equal length to the horizontal plate 1. The elastic strip 52 is preferably made of rubber material. The elastic strip 52 is integrally disposed on the side of the rigid plate 51 facing the other rigid plate 51. The elastic strip 52 is parallel to the rigid plate 51 and is of equal length. The elastic strips 52 on the two horizontal plates 1 on the same insulating bracket 103 are arranged opposite each other. The two elastic strips 52 work together to block and seal the cavity opening 4, effectively improving the problem that dust can easily enter the interior of the power rail 200 through the cavity opening 4, causing interference to the internal conductive conductor 104, reducing the conductivity of the power rail 200, and shortening its service life.

[0041] Reference Figure 3 and Figure 4 When the adapter 100 is not inserted into the conductor cavity 3, the two elastic strips 52 work together to seal and block the cavity opening 4. When the adapter 100 is inserted into the conductor cavity 3 to draw power, the power-drawing arm of the adapter 100 pushes the two elastic strips 52 toward the rigid plate 51 on which it is located, so that the power-drawing arm can pass through the cavity opening 4 and be inserted into the conductor cavity 3. It is worth noting that the two elastic strips 52 can abut against each other or form a gap on the side wall away from the rigid plate 51. The specific positional relationship between the two elastic strips 52 can be reasonably selected and adjusted according to the usage scenario and usage requirements.

[0042] Reference Figure 3 and Figure 4 The elastic strip 52 has an elastic cavity 53 extending through it along its own axis. The elastic cavity 53 increases the contraction space of the elastic strip 52, making the elastic strip 52 have a greater deformation capacity, so as to avoid the cavity opening 4 and facilitate the insertion of the power take-off arm of the adapter 100.

[0043] Reference Figure 3 and Figure 4The elastic strip 52 is also integrally provided with multiple friction ridges 54. In this embodiment, the number of friction ridges 54 on any elastic strip 52 is set to three, and they extend along the axial direction of the elastic strip 52. The friction ridges 54 are located on the side of the elastic strip 52 away from the rigid plate 51 and on the side of the elastic strip 52 away from the conductor cavity 3. When the power-taking arm of the adapter 100 is inserted, the power-taking arm first contacts the friction ridges 54 on the elastic strip 52. Due to the friction of the friction ridges 54, the elastic strip 52 is pushed to move and deform towards the conductor cavity 3, and at the same time, the elastic strip 52 is pushed to retract towards the rigid plate 51. The setting of the friction ridges 54 changes the surface contact between the elastic strip 52 and the power-taking arm to a line contact, reducing the friction between the elastic strip 52 and the power-taking arm, making the process of the power-taking arm entering or retracting from the conductor cavity 3 smoother.

[0044] Conductive conductor 104 can be made of conductive materials such as copper, see reference. Figure 2 and Figure 3 The conductive conductor 104 is rod-shaped with an approximately trapezoidal cross-section to fit the conductor mounting cavity 6. The conductive conductor 104 is fixedly installed within the conductor mounting cavity 6. In this embodiment, four conductive conductors 104 are used, mounted in pairs on two insulating supports 103. On one insulating support 103, one of the two conductive conductors 104 is electrically connected to the live wire, and the other to the ground wire; on the other insulating support 103, one of the two conductive conductors 104 is electrically connected to the neutral wire, and the other to the ground wire.

[0045] Reference Figure 1 and Figure 2 Terminal 102 is installed at the open end of the U-shaped track housing 101, and the two cooperate to form a ring. Multiple terminal conductors in terminal 102 are respectively connected to conductive conductors 104 in insulating bracket 103. The other end of terminal 102 is connected to the power supply, thereby realizing the power connection of the electric track 200.

[0046] The implementation principle of the insulating bracket, power rail 200, and rail socket in this application embodiment is as follows: When the adapter 100 is inserted into the power rail 200 to draw power, the adapter 100 is first installed in the adapter mounting cavity 105 of the rail housing 101. Then, two power-drawing arms are driven to extend from the adapter 100, and the power-drawing arms pass through the cavity opening 4 and are inserted into the conductor cavities 3 of the two insulating brackets 103. During the insertion process, the power-drawing arms push the safety door 5 to retract, the safety door 5 opens the cavity opening 4, and the power-drawing arms extend into the conductor cavities 3, making contact with the conductive conductors 104 on the upper and lower sides, thereby realizing that the adapter 100 draws power from the power rail 200.

[0047] By installing a safety door 5 at the opening of the track cavity 106 of the insulating bracket 103, the cavity opening 4 is blocked when the adapter 100 is not inserted into the insulating bracket 103, and opened when the adapter 100 is inserted into the insulating bracket 103. This prevents dust from entering the interior of the power track 200 through the cavity opening 4, reduces interference caused by dust to the conductive conductor 104 inside the insulating bracket 103, ensures the conductivity and service life of the power track 200, and improves the safety of using the power track 200.

[0048] 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.
