[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0026] like Figure 1-Figure 4 As shown, a power supply structure and an electrical device for a power rail are provided. The power supply structure for the power rail includes a plug tongue 1 and an elastic contact piece 2. The plug tongue 1 includes a front cover plate 101 and a rear cover plate 102. The elastic contact piece 2 is installed between the front cover plate 101 and the rear cover plate 102. The front cover plate 101 and the rear cover plate 102 are fixedly connected by ultrasonic welding.

[0027] Specifically, the elastic contact piece 2 is fixedly installed between the front cover plate 101 and the rear cover plate 102 by ultrasonic welding, and the process is simple and efficient. After the front cover plate 101 and the rear cover plate 102 are matched, during the ultrasonic closing process, the contact between the front cover plate 101 and the rear cover plate 102 will generate friction heat and melt each other, which is convenient for welding between the front cover plate 101 and the rear cover plate 102. When the ultrasonic wave recedes, the front cover plate 101 and the rear cover plate 102 will be welded and fixed together, thereby ensuring the stable assembly between the front cover plate 101 and the rear cover plate 102.

[0028] Further, if Figure 1-Figure 3 As shown, one end of the elastic contact piece 2 is provided with an electrical connection terminal 201, and the electrical connection terminal 201 protrudes outward.

[0029] Specifically, the outer protruding design of the power connection terminal 201 makes it easier and more stable to contact the corresponding electrical conductor in the power track. Such a design helps to provide a stable electrical connection and reduce the risk of poor contact; it can increase the surface area of ​​the power connection terminal in contact with the conductive copper tube in the power track, thereby reducing contact resistance and improving power transmission efficiency; the protruding power connection terminal 201 can be easily and quickly connected.

[0030] Further, if Figure 3 and Figure 4 As shown, the power connection terminal 201 is in a U-shape or a bow-shape.

[0031] Specifically, the U-shaped or bow-shaped design allows the power connection terminal 201 to have a certain degree of elasticity and can be adaptively adjusted when inserted into or abutted against the power rail, thereby ensuring better contact with the conductive copper tube in the power rail and stable power transmission.

[0032] Further, if Figure 1 , Figure 2 and Figure 4 As shown, the front cover plate 101 and the rear cover plate 102 are provided with openings 103 for mounting the power connection terminal 201 , and the power connection terminal 201 can be elastically positioned on the openings 103 .

[0033] Specifically, the power terminal 201 can be installed on the opening 103 by elastic positioning, which makes the assembly process simpler and faster. The opening 103 provides stable physical support for the power terminal 201, which helps to ensure accurate alignment and stable contact of the power terminal when inserted into the power track, reducing power loss and potential failures caused by poor contact.

[0034] Further, if Figure 3 As shown, a mounting cavity 104 for mounting the elastic contact piece 2 is formed between the front cover plate 101 and the rear cover plate 102 .

[0035] Specifically, the design of the mounting cavity 104 can help ensure that the elastic contact piece 2 is in the correct position and angle, reduce electrical contact resistance, and improve power transmission efficiency; at the same time, it also helps to maintain good alignment between the power terminal 201 and the power track, avoid poor contact and prevent the contact piece from being directly impacted or damaged by the outside during use.

[0036] Further, if Figure 1-Figure 4 As shown, a plurality of elastic contact pieces 2 are provided, and the plurality of elastic contact pieces 2 are staggeredly arranged on the inserting tongue 1 .

[0037] Specifically, the elastic contact piece 2 includes a live wire elastic contact piece, a neutral wire elastic contact piece and a ground wire elastic contact piece. When the elastic contact piece 2 is plugged into the power track, the live wire elastic contact piece, the neutral wire elastic contact piece and the ground wire elastic contact piece contact the conductive copper tube in the power track to obtain electricity. The power connection terminals 201 on the live wire elastic contact piece and the neutral wire elastic contact piece are located on the front cover plate 101 and are arranged in a high and low staggered manner; the power connection terminal 201 on the neutral wire elastic contact piece is located on the rear cover plate 102, which greatly reduces the risk of electrical failures, such as short circuit problems.

[0038] Furthermore, an elastic buckle 105 is provided on the plug tongue 1 , and the plug tongue 1 is inserted and fixed in the power rail through the elastic buckle 105 .

[0039] Specifically, in order to facilitate the installation and fixation of the plug tongue 1 in the power rail, the elastic buckle 105 is designed to reduce the problem of the plug tongue 1 falling off due to vibration or external impact.

[0040] Further, if Figure 4 As shown, the other end of the elastic contact piece 2 is provided with a connecting end 202; the elastic contact piece 2 is an integrally formed structure.

[0041] Specifically, the elastic contact piece 2 is convenient for being electrically connected to an electrical device through the design of the connection end 202; the use of the one-piece molding technology can simplify the production process, reduce the manufacturing steps and the required materials, and thus reduce the production cost.

[0042] An electrical component is provided with a slot matched with the power taking structure for the power track, and the electrical component comprises a track socket, a USB charger, a lighting lamp, a Bluetooth speaker, or a power adapter.

[0043] Specifically, the electrical device cooperates with the plug tongue 1 so that the plug tongue 1 supplies power to the electrical device. In addition to the electrical appliances described above, the electrical device can also be other electrical devices, which are not listed here one by one and have multiple uses and application scenarios.

[0044] The second embodiment, as Figure 5 and Figure 6 As shown, the power supply structure and electrical device for the power rail are different from the first embodiment in that at least two groups of elastic contact pieces 2 are provided, and the at least two groups of elastic contact pieces 2 are respectively arranged on the two side surfaces of the plug tongue 1 and are symmetrically arranged front to back.

[0045] Specifically, at least two groups of elastic contact pieces 2 are convenient for users to use. Users can use them directly after inserting them into the power rail without distinguishing the matching relationship between the plug tongue 1 and the power rail, which greatly simplifies the installation process and reduces the possibility of installation errors.
