Therefore, they should not be construed as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0041] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0042] Reference Figures 1 to 8 As shown, the utility model provides a power track of a hidden track socket, including a power track box 1 and a busbar group 2.

[0043] The power track box 1 has an accommodating cavity 10 inside, and the socket surface 11 of the power track box 1 has a long guide groove 12 for inserting the power collecting body of the adapter. The guide groove 12 passes through the socket surface 11 of the power track box 1 and is connected to the accommodating cavity 10; the busbar group 2 includes at least two busbars 3 spaced apart from each other, and each busbar 3 is the same. The busbar 3 is connected to the inner wall of the accommodating cavity 10, and the length direction is the same as the length direction of the guide groove 12.

[0044] When the power rail of the hidden track socket provided by this embodiment is used to power the adapter, since the socket surface 11 of the power track box 1 (a surface used to plug or dock with the adapter) has a guide groove 12, and the guide groove 12 is connected to the accommodating cavity 10 inside the power track box 1, the power-collecting body of the adapter can be plugged into the accommodating cavity 10 through the guide groove 12, and contact the busbar 3 located in the accommodating cavity 10 to achieve power collection. In addition, since the guide groove 12 is long and the length direction of the busbar 3 is the same as the length direction of the guide groove 12, the power-collecting body plugged into the guide groove 12 can move along the length direction of the guide groove 12 according to the user's needs until it moves to a suitable position while ensuring contact with the busbar 3. In this way, the flexibility of use of the track socket is improved.

[0045] In addition, since the busbars 3 in the power rail are identical, not only is the versatility of the parts improved, but the manufacturing cost of the rail socket is also effectively reduced.

[0046] In this embodiment, the power track is applicable not only to a two-pin adapter (an adapter with two pins), but also to a three-pin adapter (an adapter with three pins). When the power track is applicable to a two-pin adapter, the busbar group 2 includes two busbars 3, and the two busbars 3 are respectively located on the inner wall of the accommodating cavity 10. More specifically, the two busbars 3 are a live busbar and a neutral busbar, and the live busbar and the neutral busbar are installed on the inner wall on the same side of the guide groove 12. When the track socket is applicable to a three-pin adapter, the busbar group 2 includes three busbars 3, two of which are respectively located on the inner wall on the same side of the guide groove 12, and the other busbar is arranged on the side opposite to the guide groove 12. In the vertical direction, the two busbars 3 located on the inner wall on the same side of the guide groove 12 are arranged in a staggered manner. In this way, the creepage distance between the two busbars 3 can be as large as possible within a limited space to eliminate potential safety hazards in electrical use.

[0047] Of course, in other embodiments, the position of the busbar 3 in the accommodating cavity 10 can also be adjusted according to the adapter that needs to be adapted, and the present disclosure does not limit this.

[0048] In order to make the power track more beautiful, more convenient to install and more efficient after installation, in this embodiment, a first guide plate 4 and a second guide plate 5 are provided on both sides of the guide groove 12, and the length direction of the first guide plate 4 and the second guide plate 5 is the same as the length direction of the guide groove 12. The first guide plate 4 and the second guide plate 5 are raised toward the socket surface 11, so that the angle between the first guide plate 4 and the socket surface 11 forms a first mounting platform 40 for mounting the decorative panel 120, and the angle between the second guide plate 5 and the socket surface 11 forms a second mounting platform 50 for mounting the decorative panel 120. The length direction of the first mounting platform 40 and the second mounting platform 50 is the same as the length direction of the guide groove 12, and a guide opening 6 connected to the guide groove 12 is formed between the first guide plate 4 and the second guide plate 5.

[0049] Therefore, when installing the power rail, a power rail groove is reserved in the carrier 17 (decorative wall, skirting) in advance. The power rail is first installed in the power rail groove, and finally the decorative panel 18 is installed on the first mounting platform 40 and the second mounting platform 50. After the installation, only the guide opening of the power rail is exposed. Through the guide opening 6, the power collection body of the adapter can pass through the guide groove 12 and be inserted into the accommodating cavity 10 to contact the busbar to achieve power collection. After installation, the overall profile of the power rail is smaller, the appearance is more beautiful, and the installation is more convenient and efficient.

[0050] In order to facilitate busbar wiring, in this embodiment, preferably, a wiring assembly 7 for electrically connecting to the busbar 3 is further provided on the power track box 1 .

[0051] Among them, the wiring assembly 7 includes a wiring seat 70, a wiring terminal 71 and a wiring seat back cover 72 that can be detachably fixed to the wiring seat 70. The number of wiring terminals 71 is the same as the number of busbars 3. One end of the wiring terminal 71 is electrically connected to the busbar 3, and the other end of the wiring terminal 71 is provided with a wire jack 710 for the wire to pass through; the wiring terminal 71 is also provided with a bolt hole 711 connected to the wire jack 710, and the bolt hole 711 is provided with a fastener 712 for tightening the wire, and the axes of the wire jack 710 and the bolt hole 711 are perpendicular to each other.

[0052] With such a configuration, during installation, the wire is inserted into the wire insertion hole 710, and then the wire in the wire insertion hole is tightened and fixed by the fastener 712 in the bolt hole 711, and the contact surface between the fastener 712 and the wire is flat, so that the wire and the contact wire terminal are in stable contact, ensuring normal conductivity.

[0053] Of course, the wiring assembly 7 can also be electrically connected to the busbar via a circuit board 73 .

[0054] Specifically, the wiring assembly 7 also includes a circuit board 73, which is fixed on the wiring seat 70. The circuit board 73 can be screwed to the wiring seat 70 by screws, and a positioning column 700 for positioning the circuit board 73 is provided on the wiring seat 70. The circuit board 73 is provided with a positioning hole 730 that matches the positioning column 700, so that the circuit board 73 and the contact seat 70 can be quickly assembled.

[0055] In addition, the busbar 3 and the terminal block 71 are electrically connected to the circuit board 73 respectively. The busbar 3 is connected to one end of the circuit board 73, and the terminal block 71 is connected to the other end of the circuit board, so that the layout and assembly of the circuit board 73 on the structure of the terminal block 70 can be simpler.

[0056] As can be seen from the foregoing, the track socket provided in this embodiment, by providing a guide slot 12 on the power track box 1 and disposing a busbar 3 within the power track box 1 that extends in the same direction as the guide slot 12, enables the adapter's pins to move relative to the track socket, thereby improving the track socket's usability. The following describes the relevant components, the power track box 1 and the busbar assembly 2, in turn.

[0057] In this embodiment, the power track box 1 is a long strip-shaped structural member, and the length direction of the guide groove 12 is the same as the length direction of the power track box 1, so that the power track box 1 can provide sufficient layout space for the guide groove 12. In addition, in order to facilitate the plugging of the adapter, the socket surface 11 is one side of the power track box 1, and the power track box 1 is installed on the carrier 17 through the other side. In other words, when the user plugs in the adapter, it is plugged in from one side of the socket surface 11, and the carrier can provide sufficient supporting force so that the pins of the adapter can be smoothly inserted into the guide groove 12. Of course, in other embodiments, based on actual conditions, if the bottom surface of the power track box 1 is fixed on the carrier, then the socket surface correspondingly is the opposite top surface of the power track box 1, so as to facilitate the plugging of the adapter.

[0058] In this embodiment, the inner wall of the accommodating cavity 10 has a long strip-shaped mounting groove 8, the length direction of the mounting groove 8 is the same as the length direction of the guide groove 12, the mounting groove 8 corresponds one-to-one to the busbar 3, and the mounting groove 8 is used to accommodate the corresponding busbar 3.

[0059] The mounting groove 8 provides space for the installation of the busbar 3 on the power track box 1, so that the busbar 3 can be firmly connected to the power track box 1. Since the length direction of the busbar 3 needs to be the same as the length direction of the guide groove 12, in order to make the mounting groove 8 better accommodate the busbar 3, the mounting groove 8 is also correspondingly designed to be long and narrow, and the length direction of the mounting groove 8 is the same as the length direction of the guide groove 12. In other words, in the process of assembling the busbar 3, since the position of the mounting groove 8 relative to the guide groove 12 has been determined, it is only necessary to assemble the busbar 3 into the mounting groove 8 to ensure the position of the busbar 3 relative to the guide groove 12, that is, the length direction of the busbar 3 is the same as the length direction of the guide groove 12. In this way, the assembly efficiency of the busbar 3 can be effectively improved.

[0060] It should be noted that since the busbars 3 are the same, in order to ensure the same installation stability of the busbars 3, the corresponding installation slots 8 should also be the same. This not only improves the assembly efficiency, but also simplifies the structure of the power track box 1 and effectively reduces the manufacturing cost of the power track box 1.

[0061] In this embodiment, the mounting slot 8 includes a slot body 80 and two flanges 81. The slot body 80 is located on the inner wall of the accommodating cavity 10, and the slot opening 82 of the slot body 80 faces away from the inner wall of the accommodating cavity 10. The two flanges 81 are respectively located at the slot openings 82 of the slot body 80 and are arranged opposite each other. The side of the flanges 81 facing the slot bottom 83 of the slot body 80 abuts against the busbar 3.

[0062] The slot body 80 forms the main body of the mounting slot 8, providing space for the busbar 3. The slot opening 82 of the slot body 80 forms the opening of the slot body 80 on the power rail box 1, providing access for the busbar 3 to be installed and removed from the slot body 80. The flanges 81 are positioned on either side of the slot opening 82, arranged in a relative manner, to securely engage the busbar 3 and prevent it from falling out of the slot body 80. Furthermore, during installation, the busbar 3 can be engaged simply by the flanges 81, eliminating the need for additional assembly parts (such as screws). This further improves the efficiency of busbar 3 assembly.

[0063] For example, the inner contour of the trough body 80 is in the shape of an elongated strip, and its length direction is the same as the length direction of the guide groove 12. Designing the inner contour of the trough body 80 into the above shape can make the inner contour of the trough body 80 better match the busbar 3, so as to more stably accommodate the busbar 3, prevent the busbar 3 from shaking in the trough body 80, and thus avoid the problem of poor contact.

[0064] Exemplarily, the flange 81 is in the shape of an elongated strip, and its length direction is the same as the length direction of the guide slot 12. Moreover, in order to allow the busbar 3 to fully abut against the flange 81, the length of the flange 81 should be the same as the length of the slot body 80.

[0065] In this embodiment, a front cover 13 and a rear cover 14 are movably provided at the front and rear ends of the power track box 1, respectively. The front cover 13 is located at one end of the power track box 1 and is detachably connected to the screw posts 19 on the power track box 1 via bolts. The rear cover 14 is located at the other end of the power track box 1 and is detachably connected to the screw posts 19 on the power track box 1 via bolts. This improves the ease of assembly between the end covers 13 and rear cover 14 and the power track box 1.

[0066] For example, the power rail box 1 can be made of various materials with good mechanical properties, such as stainless steel, aluminum alloy, or engineering plastics. This embodiment does not limit the material of the power rail box 1. The power rail box 1 can be formed by a stamping process, a casting process, or a cutting process. This embodiment does not limit the processing method of the power rail box 1.

[0067] It is understandable that when the power track box 1 is made of stainless steel or aluminum alloy, the busbar 3 needs to be fixed to the inner wall of the power track box 1 through an insulating member to prevent the power track box 1 from leaking electricity.

[0068] Since the power track box 1 needs to accommodate the busbar 3, and the busbar 3 is energized during operation, in order to ensure the electrical safety of the track socket, in this embodiment, the power track box 1 includes a shell 15 and an isolator 16. The isolator 16 is fixed to the inner wall of the accommodating cavity 10, that is, the shell 15 is sleeved on the outside of the isolator 16 to protect the isolator 16 and improve the structural strength of the track socket. The isolator 16 is made of insulating material, and the busbar group 2 is connected to the isolator 16 to provide insulation protection through the isolator 16.

[0069] Exemplarily, the isolating member 16 is made of plastic and can be manufactured through an integral molding process to improve manufacturing efficiency and reduce manufacturing costs.

[0070] In order to ensure that the isolating member 16 can be stably fixed inside the housing 15, a positioning structure 9 is connected between the housing 15 and the isolating member 16. The positioning structure 9 includes an abutting ridge 90 and a positioning groove 91. In other words, the abutting ridge 90 can be provided on the isolating member 16 or the housing 15, and the positioning groove 91 can be provided on the isolating member 16 or the housing 15.

[0071] In this embodiment, in order to facilitate the assembly and disassembly between the isolation member 16 and the shell 15, an abutting protrusion 90 and a positioning groove 91 are provided on the shell 15, and an abutting protrusion 90 and a positioning groove 91 are provided on the isolation member 16, wherein the abutting protrusion 90 on the shell 15 corresponds to the position of the positioning groove 91 on the isolation member 16, and the positioning groove 91 on the shell 15 corresponds to the position of the abutting protrusion 90 on the isolation member 16. After matching through the above-mentioned structure, the adapter can be prevented from shaking inside the accommodating cavity 10.

[0072] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
