The power taking part 12 can be inserted into the slide groove 23 of the power rail to take electricity, and the positions and numbers of the live wire power taking pole 51, the neutral wire power taking pole 52 and the ground wire power taking pole 53 are respectively adapted to the positions and numbers of the live wire conductive socket 31, the neutral wire conductive socket 32 ​​and the ground wire conductive socket 33 in the power rail 20.

[0028] The plug-in part 11 and the power-taking part 12 are hinged to each other, and a receiving groove 121 for receiving the live wire power-taking pole 51, the neutral wire power-taking pole 52 and the ground wire power-taking pole 53 is provided inside the power-taking part 12. A rotating shaft 15 is provided at the bottom of the plug-in part 11, and the live wire power-taking pole 51, the neutral wire power-taking pole 52 and the ground wire power-taking pole 53 are fixedly connected to the rotating shaft 15.

The direction of movement of the push rod 71 is perpendicular to the direction of movement of the locking pin 72. The moving path of the locking pin 72 is perpendicular to the rotation direction of the plug-in part 11. A limiting groove 73 is provided on the plug-in part 11. The limiting groove 73 is located in front of the free end of the push rod 71. When an external force is applied to the button 13, the free end of the push rod 71 will enter the limiting groove 73.

In other embodiments, two live wire power poles 51 may also be provided, which can play a role of diversion when the power rail 20 is fully loaded or overloaded, which is safer, and the live wire contact will be more stable, and the copper sheet will generate less heat and lower temperature. The live wire conductive socket 31, the neutral wire conductive socket 32, and the ground wire conductive socket 33 in the power rail correspond to the number and position of the live wire power pole 51, the neutral wire power pole 52, and the ground wire power pole 53.

[0036] The power adapter is provided with a positioning member 14 fixedly connected to the power supply unit 12, and the positioning member 14 is provided on the lower bottom surface of the annular support plate 113 of the power supply unit 12. The power rail is provided with a long strip positioning groove 24 adapted to the position and shape of the positioning member 14. When the power supply unit 12 is correctly inserted into the power rail 20, the positioning member 14 will be inserted into the positioning groove 24, and can also assist when rotating the power supply unit 11 to prevent the power supply unit 12 from being subjected to excessive force.

[0037] refer to Figure 2 As shown, the power rail 20 includes a long rail housing 21, and two sets of M-shaped jacket positioning frames 22 made of insulating material are arranged in the rail housing 21. The outer side of the jacket positioning frame 22 is provided with a plurality of first buckles 221, and the inner surface of the rail housing 21 is provided with a plurality of second buckles 211 that are adapted to the position and shape of the first buckles 221221. The first buckle 221 interacts with the second buckle 211 to keep the relative position of the jacket positioning frame 22 and the rail housing 21 fixed, and prevent the jacket positioning frame 22 from being pulled out of the rail housing 21. Four jacket positioning grooves 25 are arranged in the jacket positioning frame 22, two jacket positioning grooves 25 are arranged up and down on the left, and two jacket positioning grooves 25 are arranged up and down on the right. The jacket positioning frame 22 and the rail housing 21 are connected in a snap-fit ​​manner, and the jacket positioning groove 25 is connected in a snap-fit ​​manner with the live wire conductive socket 31, the neutral wire conductive socket 32 ​​and the ground wire conductive socket 33. The live wire conductive socket 31 is installed in the upper left jacket positioning groove 25, the neutral wire conductive socket 32 ​​is installed in the upper right jacket positioning groove 25, and the ground wire conductive sockets 33 are installed in the lower two jacket positioning grooves 25. Thus, double grounding can make the use of electricity safer.

[0038] In other embodiments, two live wire conductive sockets 31 and one ground wire conductive socket 33 may also be provided, and the positions and numbers of the live wire conductive socket 31, the neutral wire conductive socket 32 ​​and the ground wire conductive socket 33 are adapted to the positions and numbers of the live wire power taking pole 51, the neutral wire power taking pole 52 and the ground wire power taking pole 53 of the power adapter, thereby playing a shunting role when the power adapter is fully loaded or overloaded, which is safer, the live wire contact will be more stable, and the copper sheet will generate less heat and lower temperature.

[0039] Figure 5-6 The diagram schematically shows the state of a power adapter according to an embodiment of the present invention when it is inserted into a power rail and locked on the power rail.

[0040] refer to Figure 5-6 As shown, in this embodiment, the power rail 20 is arranged horizontally. When the power supply unit 12 of the power adapter needs to be inserted into the power rail 20, the power adapter can be adjusted so that the button 13 is in a vertical downward state, and at this time, the protrusion 1131 on the support plate 113 is located at the right end of the arc groove 1121 of the lower cover 112. After the power supply unit 12 is fully inserted into the slide groove 23 of the power rail 20, the power supply unit 11 is rotated 90° clockwise. When the button 13 is located at the left end, the limiting groove 73 provided on the lower cover 112 of the power supply unit 11 is exactly at the free end of the locking pin 72. Under the elastic force of the second elastic component 62, the free end of the locking pin 72 enters the limiting groove 73. The locking pin 72 locks the relative position of the plug-in part 11 and the power taking part 12. At this time, the live wire power taking pole 51, the neutral wire power taking pole 52 and the ground wire power taking pole 53 originally located in the receiving groove 121 of the power taking part 12 will also be unfolded and inserted into the live wire conductive socket 31, the neutral wire conductive socket 32 ​​and the ground wire conductive socket 33 of the power track 20 respectively. At this time, the protrusion 1131 on the support plate 113 is located at the left end of the arc groove 1121 of the lower cover plate 112. The provision of the protrusion 1131 and the arc groove 1121 can make the relative rotation of the plug-in part 11 and the power taking part 12 more stable.

[0041] Only when the relative positions of the power plug-in unit 11 and the power take-off unit 12 are as Figure 6 When the locking pin 72 is in the position shown, it can enter the limiting groove 73 . When the relative positions of the power plug part 11 and the power extraction part 12 are in other states, the free end of the locking pin 72 will be pressed by the bottom surface of the lower cover 112 of the power plug part 11 .

[0042] In this embodiment, the first elastic component 61 and the second elastic component 62 are both compression springs. In other embodiments, the first elastic component 61 and the second elastic component 62 may also be tension springs, torsion springs or other elastic components.

[0043] When the power adapter needs to be removed from the power rail 20, the button 13 is pressed toward the inside of the power adapter housing to make the push rod 71 contact the free end of the locking pin 72. Since the free end of the locking pin 72 is a hemispherical surface, the push rod 71 will exert a force on the locking pin 72 to make the locking pin 72 come out of the limiting groove 73. At this time, the plug-in part 11 and the power-taking part 12 are released from the limiting groove. Continue to press the button 13 and turn the plug-in part 11 counterclockwise 90° until the button 13 is directly below, and the live wire power-taking pole 51, the neutral wire power-taking pole 52 and the ground wire power-taking pole 53 are all retracted into the receiving groove 121 of the power-taking part 12. At this time, the power adapter can be pulled out of the power rail 20.

[0044] In other embodiments, the free end of the locking pin 72 may also be a conical surface, a pyramidal surface, or an inclined surface facing the push rod 71 .

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned examples, or replace some of the technical features therein with equivalents.
