[0032] 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.

[0033] The first embodiment, as Figure 1-Figure 11As shown, a track socket is provided, including a socket body 1, on which a plug tongue 3 matching with a power track 2 is provided, on which a conductive structure 4 contacting and connected with a conductive copper tube 201 in the power track 2 is provided, the plug tongue 3 comprising a live wire contact piece 401, a neutral wire contact piece 402 and a ground wire contact piece 403, the live wire contact piece 401 and the neutral wire contact piece 402 being arranged on one side surface of the plug tongue 3 and having a first protrusion 404, the neutral wire contact piece 402 being arranged on the other side surface of the plug tongue 3 and having a second protrusion 405, the live wire contact piece 401 and the neutral wire contact piece 402 being contacting and matching with the conductive copper tube 201 through the first protrusion 404, and the neutral wire contact piece 402 being contacting and matching with the conductive copper tube 201 through the second protrusion 405.

[0034] Furthermore, a conductive copper tube 201 is disposed inside the power rail 2 .

[0035] Specifically, by optimizing the design of the plug tongue and the conductive structure, the reliability of the contact point and the overall electrical connection stability can be significantly enhanced, and power interruption and power loss caused by poor contact can be reduced, thereby improving the overall efficiency and safety of the system. The plug tongue 3 can achieve stable contact connection with the power rail through the conductive structure 4. The design of the first protrusion 404 and the second protrusion 405 increases the contact area with the conductive copper tube 201, improves the contact stability and reduces the poor contact caused by vibration or movement, so that the configuration of the live wire contact piece 401, the neutral wire contact piece 402 and the ground wire contact piece 403 allows to effectively draw electricity from the conductive copper tube 201 of the power rail 2.

[0036] Further, if Figure 1 , Figure 2 and Figure 4 As shown, the live wire contact piece 401 , the neutral wire contact piece 402 and the ground wire contact piece 403 are all arranged in a staggered manner on the plug tongue 3 .

[0037] Specifically, the live wire contact 401 and the ground wire contact 403 are staggered up and down on one side of the plug tongue 3, and the neutral wire contact 402 is at the bottom position on the other side of the plug tongue 3; the staggered contact layout can reduce the risk of short circuit between contacts. In the power system, if the live wire, neutral wire and ground wire are not in proper contact, electrical failure or electric shock accidents may occur. Through the staggered setting, the position of each contact is relatively independent, which reduces the possibility of direct electrical connection between them due to accidental contact.

[0038] Further, if Figure 1 and Figure 2 and Figure 8 As shown, an elastic buckle 301 is provided on the plug tongue 3 , and the plug tongue 3 is inserted and fixed in the power rail 2 through the elastic buckle 301 .

[0039] Specifically, by adding an elastic buckle 301 to the plug tongue 3, the insertion and fixing method of the track socket further improves the convenience and reliability of its use, which not only simplifies the installation process, but also enhances the stability of the track socket on the power track 2 and prevents the track socket from detaching from the power rail.

[0040] Further, if Figure 3 and Figure 4 As shown, the socket body 1 includes a bottom shell 101, and a snap-on structure 5 is provided between the bottom shell 101 and the plug tongue 3. The snap-on structure 5 includes a first snap-on 501 and a second snap-on 502. The first snap-on 501 is provided on the plug tongue 3, and the second snap-on 502 is provided on the bottom shell 101. When the plug tongue 3 is installed on the bottom shell 101, the first snap-on 501 is matched and connected with the second snap-on 502.

[0041] Specifically, the snap structure 5 between the socket body 1 and the bottom shell 101 simplifies the assembly process. By designing such a matching snap, the assembly can be completed without additional tools or complicated steps, making the installation and removal of the plug tongue 3 on the bottom shell 101 quick and convenient.

[0042] Further, if Figure 3 As shown, the bottom shell 101 is provided with a through hole 1011 for the insertion tongue 3 to pass through.

[0043] Specifically, the inserting tongue 3 can easily pass through the bottom shell 101 and be correctly positioned and fixed. Such a design facilitates quick assembly and disassembly and reduces the complexity of the operation during installation.

[0044] Further, if Figure 3 and Figure 5 As shown, the track socket also includes a power supply structure 6, which includes a fixing seat 601, a live wire copper sleeve 602, a neutral wire copper sleeve 603 and a ground wire copper sleeve 604. The live wire copper sleeve 602, the neutral wire copper sleeve 603 and the ground wire copper sleeve 604 are all installed on the fixing seat 601. The live wire copper sleeve 602 and the neutral wire copper sleeve 603 are respectively provided with a connecting copper sheet 605. The live wire contact piece 401 and the neutral wire contact piece 402 are electrically connected to the live wire copper sleeve 602 and the neutral wire copper sleeve 603 through the connecting copper sheet 605, and the ground wire contact piece 403 is electrically connected to the ground wire copper sleeve 604.

[0045] Specifically, the live wire copper sleeve 602, the neutral wire copper sleeve 603 and the ground wire copper sleeve 604 correspond to the connection of the live wire contact 401, the neutral wire contact 402 and the ground wire copper sleeve 604 respectively; the copper sleeve provides an efficient current transmission path and reduces resistance and heat loss; the connecting copper sheet 605 serves as the electrical connection medium between the live wire copper sleeve 602 and the neutral wire copper sleeve 603 and the live wire contact 401 and the neutral wire contact 402, ensuring a reliable electrical connection.

[0046] Further, if Figure 5-Figure 8 As shown, the socket body 1 also includes a shell 102, and a slot 1021 for mating and connecting the power supply plug is provided on the shell 102. The track socket also includes a safety protection structure 7, and the safety protection structure 7 includes a protection door outer sleeve 701 and a safety protection component 702. The safety protection component 702 is installed on the protection door outer sleeve 701. The safety protection component 702 includes a two-pole plug protection door 7021 and a three-pole plug protection door 7022. The two-pole plug protection door 7021 and the three-pole plug protection door 7022 can be displaced on the protection door outer sleeve 701.

[0047] Specifically, when a two-pole plug is inserted into the slot 1021 corresponding to the socket body 1, the two-pole plug protection door 7021 is pushed open, and the two-pole plug protection door 7021 is displaced toward the three-pole plug protection door 7022, so that the two-pole plug is plugged into the live copper sleeve 602 and the neutral copper sleeve 603; when a three-pole plug is inserted into the slot 1021 corresponding to the socket body 1, the three-pole plug protection door 7022 is pushed open, and the three-pole plug protection door 7022 is displaced toward the two-pole plug protection door 7021, so that the three-pole plug is plugged into the live copper sleeve 602, the neutral copper sleeve 603 and the ground copper sleeve 604; the above-mentioned arrangement can prevent the plug from being unable to be inserted to draw electricity when it has only one electrode, so as to ensure the safety of electrical use of electrical appliances, and can also prevent children from inserting metal needles into live parts to prevent electric shock, so as to ensure safety.

[0048] Further, if Figure 6-Figure 8 As shown, an elastic reset member 7023 is provided between the two-pole plug protection door 7021 and the three-pole plug protection door 7022 .

[0049] Specifically, one end of the elastic reset member 7023 abuts against the two-pole plug protection door 7021, and the other end of the elastic reset member 7023 abuts against the three-pole plug protection door 7022; when the two-pole plug or the three-pole plug is inserted into the corresponding slot 1021 of the socket body 1, the two-pole plug protection door 7021 or the three-pole plug protection door 7022 can squeeze the elastic reset member 7023, and when the two-pole plug or the three-pole plug is pulled out from the socket body 1, the two-pole plug protection door 7021 or the three-pole plug protection door 7022 is reset under the action of the elastic reset member 7023.

[0050] Furthermore, the elastic reset member 7023 generally adopts a spring member structure to ensure elastic force and multiple reciprocating operations. Example

[0051] like Figure 12-14 As shown, the present track socket and power track are different from the first embodiment in that: at least two groups of conductive structures 4 are provided, and the at least two groups of conductive structures 4 are respectively arranged on both side surfaces of the plug tongue 3 and are symmetrically arranged front to back.

[0052] Specifically, at least two sets of conductive structures 4 are convenient for users to use. Users can use them directly after plugging them into the power track without distinguishing the matching relationship between the track socket and the power track, which greatly simplifies the installation process and reduces the possibility of installation errors.
