[0020] The socket replaces the arrangement of the two groups of double-hole sockets above and below the three-hole socket with the arrangement of the two groups of double-hole sockets symmetrically arranged on the left and right sides above the three-hole socket, the socket layout is adjusted, especially a larger space is left between the two groups of double-hole sockets, the plug collision is avoided to a greater extent, the situation that the plug cannot be inserted into the two double-hole sockets at the same time due to a slight thickness of the plug is avoided, the compatibility of the socket is improved, moreover, the live wire conducting piece 31 and the zero wire conducting piece 32 are designed as a character shape, the arrangement of each socket on the socket is conformed to, it is ensured that each socket can be correctly wired, the internal conducting line layout of the socket is simplified, the socket assembly convenience is improved, and the installation difficulty and high manufacturing cost caused by the complex internal structure design of the seven-hole socket due to the large number of sockets are avoided.
[0021] The double-hole socket can be a flat hole or a semicircular hole, and the three-hole socket is a flat hole, and the double-hole socket and the three-hole socket of the embodiment are both designed as flat holes.
[0022] The three-hole socket comprises a first zero wire socket 42 on the left side, a first live wire socket 41 on the right side and a ground wire socket 43 on the upper side, each group of double-hole socket comprises a second live wire socket 51 and a second zero wire socket 52 arranged in an up-down manner, according to the design, after installation, the horizontal connecting piece 311 of the live wire conducting piece 31 is arranged on the upper part of the horizontal connecting piece 321 of the zero wire conducting piece 32.
[0023] The conducting assembly is connected with a wiring terminal, the wiring terminal comprises a zero wire terminal 62, a live wire terminal 61 and a ground terminal 63, correspondingly, the live wire conducting piece 31 is connected with the live wire terminal 61, the zero wire conducting piece 32 is connected with the zero wire terminal 62, and the ground wire conducting piece 33 is connected with the ground terminal 63.
[0024] The plug sleeve includes an N-pole plug sleeve, an L-pole plug sleeve 313, and an E-pole plug sleeve 331. Correspondingly, the N-pole plug sleeve 323 is arranged at the first and second zero-line plug holes 42 and 52 of the zero-line conducting member 32, the L-pole plug sleeve 313 is arranged at the first and second live-line plug holes 41 and 51 of the live-line conducting member, and the E-pole plug sleeve 331 is arranged at the ground-line plug hole 43 of the ground-line conducting member. When the plug is inserted into the plug hole and contacts the corresponding plug sleeve, the corresponding conducting member is connected to the corresponding terminal to realize power supply. When the plug is pulled out, the plug is separated from the corresponding plug sleeve and the connection is disconnected.
[0025] The N-pole plug sleeve 323 and the L-pole plug sleeve 313 have the same structure. Taking the N-pole plug sleeve 323 as an example, the N-pole plug sleeve 323 includes a first contact piece 3231, a second contact piece 3232, and a U-shaped connecting portion 3233 connecting the first and second contact pieces.

The first contact piece 3231 and the second contact piece 3232 are provided with outwardly turned guide portions 3234 at the panel 1. Since the first contact piece 3231 and the second contact piece 3232 are firmly connected together through the U-shaped connecting portion 3233, the plug is not easy to loosen or fall off when pulled out. The first contact piece 3231 is arranged on the zero-line conducting member 32 and extends outward in the direction of the panel 1, which actually increases the area of the plug insertion contact part. The second contact piece 3232 is elastic and can better adapt to the shape of the socket or plug, thereby reducing the force required for insertion and reducing the risk of damage to the plug sleeve or socket caused by excessive insertion force. The outwardly turned guide portions 3234 can guide the insertion or pulling out of the plug, making it easier and more stable to insert or pull out the plug. When pulled out, the guide portions 3234 can provide additional support, making the pulling out process more stable. Further, the second contact piece can be thickened to improve the stability and safety of the connection. Reinforcing ribs can be added to the U-shaped connecting portion 3233 to effectively enhance the mechanical strength of the N-pole plug sleeve 323, so that it is not easy to deform under the condition of multiple insertions and pull-outs, thereby increasing the stability of the plug sleeve, reducing the risk of poor contact, and ensuring the stability and safety of current transmission, thereby improving the number of insertions and pull-outs and the service life of the conducting member.
[0026] The E-pole plug sleeve 331 includes two contact pieces and a connecting block 332. The contact piece includes a contact portion 3311, which extends outward to form an outwardly turned portion 3312 in the direction of the panel 1. The contact portion 3311 extends in the direction of the rear side of the seat body 2 to form a connecting portion 3313 connected to the connecting block. The connecting portion 3313 is provided with a through hole 3314 and a spring 3315 connected to one end of the through hole. When the plug is inserted into the plug sleeve, the contact portions of the two contact pieces are pushed open, and one end of the through hole 3314 is pressed against the spring 3315. After the plug is pulled out, the spring 3315 returns to its original position, driving the contact portions 3311 of the two contact pieces to return to their original positions.
[0027] In the socket specific design, the bent connecting pieces 312, 322 of the live wire and zero wire conducting pieces 31, 32 are provided with connecting arms vertically connecting corresponding wire terminals, and the ground wire conducting piece 33 extends from the connecting block 332 towards the rear side of the seat body 2 to connect the ground terminal 63.
[0028] The live wire, zero wire and ground wire conducting pieces 31, 32, 33 are made of copper and are integrally designed with the corresponding plug-in sleeves and wire terminals.
[0029] To enhance the safety of the socket, the front side of the N-pole plug-in sleeve 323 and the L-pole plug-in sleeve 313 corresponding to the double-hole socket are provided with an integrated two-plug safety door, and the front side of the E-pole plug-in sleeve 331, the L-pole plug-in sleeve 313 and the N-pole plug-in sleeve 323 corresponding to the three-hole socket are provided with an integrated three-plug safety door.
