For example, when the first side surface 13 is parallel to the ground, the socket 100 is vertical; when the second side surface 14 is parallel to the ground, the socket is horizontal. Or, for example, when the first side surface 13 is parallel to the ground, the socket 100 is horizontal; when the second side surface 14 is parallel to the ground, the socket 100 is vertical. The socket 100 provided in this application embodiment can use the first PE terminal 20a, the first N terminal 20b, and the first L terminal 20c extending to the first side 13, or the second PE terminal 30a, the second N terminal 30b, and the second L terminal 30c extending to the second side 14, thereby being compatible with both vertical and horizontal usage scenarios and expanding the application scenarios of the socket 100.

[0031] Among them, the third PE terminal 40a, the third N terminal 40b, and the third L terminal 40c are used to connect to the power grid.

[0032] It is worth noting that, in some embodiments, the second mounting surface 12 is provided with a first PE terminal mounting position 121 for mounting the first PE terminal 20a, a first N terminal mounting position 122 for mounting the first N terminal 20b, a first L terminal mounting position 123 for mounting the first L terminal 20c, a second PE terminal mounting position 124 for mounting the second PE terminal 30a, a second N terminal mounting position 125 for mounting the second N terminal 30b, and a second L terminal mounting position 126 for mounting the second L terminal 30c; the first PE terminal mounting position 121 communicates with the second PE terminal mounting position 124, and a first through hole 121s is provided at the communication point between the first PE terminal mounting position 121 and the second PE terminal mounting position 124, the first through hole 121s being used for mounting the first PE terminal 20a, the second N terminal mounting position 122 for mounting the first N terminal 20b, the first L terminal mounting position 123 for mounting the first L terminal 20c, the second PE terminal mounting position 124 for mounting the second PE terminal 20a, the second N terminal mounting position 125 for mounting the second N terminal 20b, and the second L terminal mounting position 126 for mounting the second L terminal 20c. The first PE terminal 20a or the second PE terminal 30a is electrically connected to the third PE terminal 40a; the first N terminal mounting position 122 is connected to the second N terminal mounting position 125, and a second through hole 122s is provided at the connection between the first N terminal mounting position 122 and the second N terminal mounting position 125, the second through hole 122s being used for the first N terminal 20b or the second N terminal 30b to electrically connect to the third N terminal 40b; the first L terminal mounting position 123 is connected to the second L terminal mounting position 126, and a third through hole 123s is provided at the connection between the first L terminal mounting position 123 and the second L terminal mounting position 126, the third through hole 123s being used for the first L terminal 20c or the second L terminal 30c to electrically connect to the third L terminal 40c. Since the socket 100 is provided with a first PE terminal mounting position 121, a first N terminal mounting position 122, a first L terminal mounting position 123, a second PE terminal mounting position 124, a second N terminal mounting position 125, and a second L terminal mounting position 126, the first PE terminal mounting position 121, the first N terminal mounting position 122, and the first L terminal mounting position 123 form one set of mounting positions, and the second PE terminal mounting position 124, the second N terminal mounting position 125, and the second L terminal mounting position 126 form another set of mounting positions. That is, the socket 100 is provided with two sets of mounting positions for PE terminals, N terminals, and L terminals, so one socket 100 can be compatible with two sets of PE terminals, N terminals, and L terminals. Users can choose any set of mounting positions according to their needs, thus expanding the application scenarios of the socket 100. Specifically, for example, when the first side 13 is parallel to the ground, the socket 100 is vertical, and when the second side 14 is parallel to the ground, the socket is horizontal; or, for example, when the first side 13 is parallel to the ground, the socket 100 is horizontal, and when the second side 14 is parallel to the ground, the socket 100 is vertical.The socket 100 provided in this application embodiment can use the first PE terminal 20a located at the first PE terminal mounting position 121, the first N terminal 20b located at the first N terminal mounting position 122, and the first L terminal 20c located at the first L terminal mounting position 123, which extend to the first side 13. It can also use the second PE terminal 30a located at the second PE terminal mounting position 124, the second N terminal 30b located at the second N terminal mounting position 125, and the second L terminal 30c located at the second L terminal mounting position 126, which extend to the second side 14, thereby being compatible with both vertical and horizontal usage scenarios and expanding the application scenarios of the socket 100.

[0033] It is worth noting that, in some embodiments, the first PE terminal mounting position 121, the first N terminal mounting position 122, and the first L terminal mounting position 123 all extend to the first side 13, so that the first PE terminal 20a, the first N terminal 20b, and the first L terminal 20c can extend to the first side 13; the second PE terminal mounting position 124, the second N terminal mounting position 125, and the second L terminal mounting position 126 all extend to the second side 14, so that the second PE terminal 30a, the second N terminal 30b, and the second L terminal 30c can extend to the second side 14. When the first PE terminal mounting position 121, the first N terminal mounting position 122, and the first L terminal mounting position 123 all extend to the first side 13, the installed first PE terminal 20a, first N terminal 20b, and first L terminal 20c can also extend to the first side 13, thus not occupying the space where the second side 14 is located. When the second PE terminal mounting position 124, the second N terminal mounting position 125, and the second L terminal mounting position 126 all extend to the second side 14, the installed second PE terminal 30a, second N terminal 30b, and second L terminal 30c can also extend to the second side 14, thus not occupying the space where the first side 13 is located. The socket 100 has a compact structure and a wide range of applications. In addition, through this arrangement, the structure of the base 10 is clear, facilitating the installation of the first PE terminal 20a, first N terminal 20b, and first L terminal 20c, and facilitating the installation of the second PE terminal 30a, second N terminal 30b, and second L terminal 30c.

[0034] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 5 The base 10 also includes a third side 15 connected to the second side 14. The third side 15 is provided with a snap-fit ​​member 151 for snapping the second PE terminal 30a. By providing the snap-fit ​​member 151, when the second PE terminal 30a extends around the third side 15 to the second side 14, the second PE terminal 30a is restricted, thereby improving the structural stability and compactness of the socket 100.

[0035] It is worth noting that in some embodiments, please refer to the following: Figure 2 , Figures 6 to 9 The third PE terminal 40a passes through the first through hole 121s from the first mounting surface 11 and is used to electrically connect with the first PE terminal 20a or the second PE terminal 30a; the third N terminal 40b passes through the second through hole 122s from the first mounting surface 11 and is used to electrically connect with the first N terminal 20b or the second N terminal 30b; the third L terminal 40c is electrically connected with the first L terminal 20c or the second L terminal 30c through the third through hole 123s. The third PE terminal 40a is used to connect to the ground wire of the power grid, the third N terminal 40b is used to connect to the neutral wire of the power grid, and the third L terminal 40c is used to connect to the live wire of the power grid. The arrangement of the third PE terminal 40a, the third N terminal 40b, and the third L terminal 40c facilitates the connection of the socket 100 to the power grid.

[0036] It is worth noting that in some embodiments, please refer to the following: Figures 8 to 11 The socket 100 also includes a fuse 50, one end of which is electrically connected to the third L terminal 40c, and the other end of which is electrically connected to the first L terminal 20c or the second L terminal 30c. Because the third L terminal 40c is connected to the live wire of the power grid, when an overcurrent or short circuit fault occurs in the live wire, the fuse 50 melts, disconnecting the live wire from the first L terminal 20c or the second L terminal 30c, thereby protecting the socket 100 and the electrical equipment and improving the safety of the socket 100.

[0037] It is worth noting that in some embodiments, please refer to the following: Figures 2 to 4 The second mounting surface 12 is further provided with a mounting groove 127. The bottom of the mounting groove 127 has a fourth through hole 124s and a fifth through hole 125s. The socket 100 also includes a connecting piece 60, which is disposed in the mounting groove 127. One end of the connecting piece 60 is electrically connected to the third L terminal 40c through the fourth through hole 124s, and the other end of the connecting piece 60 is electrically connected to one end of the fuse 50 through the fifth through hole 125s. The other end of the fuse 50 is electrically connected to the first L terminal 20c or the second L terminal 30c through the third through hole 123s. The connecting piece 60 enables electrical connection between the third L terminal 40c, the fuse 50, and the first L terminal 20c or the second L terminal 30c, resulting in a simple structure and reliable connection. Furthermore, placing the connecting piece 60 within the mounting groove 127 makes the internal structure of the socket 100 more compact, saving space. In addition, the mounting slot 127 facilitates the installation and removal of the connecting piece 60, making maintenance and replacement easier.

[0038] It is worth noting that in some embodiments, please refer to the following: Figures 8 to 11 The socket 100 further includes a first metal clip 70 and a second metal clip 80. The first metal clip 70 is disposed at one end of the fuse 50, and the other end of the connecting piece 60 is electrically connected to one end of the fuse 50 through the first metal clip 70. The second metal clip 80 is disposed at the other end of the fuse 50, and the other end of the fuse 50 is electrically connected to the first L terminal 20c or the second L terminal 30c through the second metal clip 80. The arrangement of the first metal clip 70 and the second metal clip 80 improves the stability and reliability of the connection between the fuse 50 and the connecting piece 60, and between the fuse 50 and the first L terminal 20c or the second L terminal 30c. Simultaneously, the first metal clip 70 and the second metal clip 80 have good conductivity, ensuring smooth current transmission and reducing energy loss. Furthermore, the first metal clip 70 and the second metal clip 80 also possess a certain degree of elasticity and toughness, capable of adapting to minor deformations or vibrations that may occur during use, thereby maintaining connection stability.

[0039] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 1 The first mounting surface 11 is recessed to form a receiving groove 111s. The bottom of the receiving groove 111s has a first through hole 121s, a second through hole 122s, and a fourth through hole 124s. Please refer to the following: Figures 8 to 11 The third PE terminal 40a, which is connected to the first PE terminal 20a or the second PE terminal 30a through the first through hole 121s, can be accommodated in the receiving groove 111s. The third N terminal 40b, which is connected to the first N terminal 20b or the second N terminal 30b through the second through hole 122s, can be accommodated in the receiving groove 111s. The third L terminal 40c, which is connected to the first L terminal 20c or the second L terminal 30c through the fourth through hole 124s, the fifth through hole 125s, the connecting piece 60, the fuse 50, and the third through hole 123s, can be accommodated in the receiving groove 111s. This effectively protects the third PE terminal 40a, the third N terminal 40b, the third L terminal 40c, and the connecting parts from external interference or damage.

[0040] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 1 The first mounting surface 11 is recessed to form a receiving groove 112s, and the bottom of the receiving groove 112s has the third through hole 123s and the fifth through hole 125s. Please refer to the following: Figures 8 to 11The fuse 50 can be accommodated in the receiving groove 112s, thereby facilitating the electrical connection of the third L terminal 40c to the first L terminal 20c or the second L terminal 30c through the fourth through hole 124s, the connecting piece 60, the fifth through hole 125s, the fuse 50, and the third through hole 123s. The receiving groove 112s can also provide protection for the fuse 50.

[0041] Additionally, in some embodiments, please refer to the following: Figure 7 and Figure 10 The socket 100 also includes a cover plate 90, which covers the opening of the receiving groove 112s, thereby facilitating the maintenance of the fuse 50.
