[0044] Please refer to Figure 1 and Figure 2 A power strip according to an embodiment of the present invention includes: a shell 1, a live wire 2, a neutral wire 3 and a ground wire 4.

[0045] The surface of the housing 1 is provided with a three-phase four-hole socket 11 and a single-phase socket. The three-phase four-hole socket 11 is an industrial socket with a voltage of 380V-440V, and the three-phase socket is a household socket with a voltage of 220V-250V.

[0046] The three-phase four-hole jack 11 and the single-phase jack 12 can be arranged on the same surface of the housing 1 or on different surfaces, such as the three-phase four-hole jack 11 on the top surface of the housing 1 and the single-phase jack on the side surface of the housing 1.

[0047] The live wire 2 is arranged inside the housing 1 , three sockets of the three-phase four-hole socket 11 are connected to the live wire 2 , and one socket of the single-phase socket is connected to the live wire 2 .

[0048] The neutral line 3 is arranged inside the housing 1 , and the other socket of the single-phase socket is connected to the neutral line 3 .

[0049] The ground wire 4 is arranged inside the housing 1 , and another socket of the three-phase four-hole socket 11 is connected to the ground wire 4 .

[0050] The power strip of this embodiment is provided with a live wire 2, a ground wire 4 and a neutral wire 3 inside the shell 1, which can meet the requirements of connecting the live wire 2 and the ground wire 4 to the three-phase four-hole socket 11, and at the same time meet the requirements of connecting the live wire 2 and the neutral wire 3 to the single-phase socket 12. In this way, it is possible to simultaneously set the three-phase four-hole socket 11 and the single-phase socket on the same power strip, thereby facilitating use and simplifying wiring operations.

[0051] The power strip of this embodiment also includes a power strip switch 5, which includes a first switch body 51 and a first control component 52 arranged on the first switch body 51. The first switch body 51 is arranged inside the shell 1, and the first switch body 51 is connected to the live wire 2. At least a part of the first control component 52 is arranged on the surface of the shell 1, and the first control component 52 is used to control whether the live wire 2 is energized.

[0052] The socket switch 5 controls whether the live wire 2 is energized, and the three-phase four-hole socket 11 and the single-phase socket are both connected to the live wire 2, so the socket switch 5 can control whether the three-phase four-hole socket 11 and the single-phase socket are energized.

[0053] At least a portion of the first control member 52 is disposed on the surface of the housing 1, allowing the user to control the power strip without opening the housing 1. For the structural principle of the first switch body 51, please refer to Figure 5 A connecting piece 511 is provided on the live wire 2. Turning the first control member 52 can control whether the connecting piece 511 contacts the sheet connected to the external live wire 2. Different postures of the first control member 52 control whether the connecting piece 511 is overlapped. When overlapped, the live wire 2 is energized, and the three-phase four-hole socket 11 and the single-phase socket are energized. When not overlapped, the live wire 2 is not energized, and the three-phase four-hole socket 11 and the single-phase socket are also not energized.

[0054] It should be pointed out here that the relevant technology of the power strip switch 5 is the existing technology, and the principle of the power strip switch 5 will not be described in detail here. In other embodiments, switches of other structural forms can also be used to control whether the live wire 2 is energized.

[0055] The power strip of this embodiment also includes a single-phase switch 6, which includes a second switch body 61 and a second control component 62 arranged on the second switch body 61. The second switch body 61 is arranged inside the shell 1, and at least a portion of the second control component 62 is arranged on the surface of the shell 1.

[0056] The live wire 2 includes a three-phase section 21 and a single-phase section 22 , which are connected via a second switch body 61 . The second control element 62 is used to control whether the single-phase section 22 is energized.

[0057] Single-phase switch 6 controls whether single-phase section 22 is energized. All single-phase outlets are connected to single-phase section 22, so single-phase switch 6 can control whether single-phase outlets are energized. When three-phase four-outlet outlet 11 is energized, single-phase switch 6 controls whether single-phase outlet 12 is energized. When three-phase four-outlet outlet 11 is energized, all single-phase outlets are energized, regardless of the state of single-phase switch 6.

[0058] At least a portion of the second control member 62 is disposed on the surface of the housing 1, allowing the user to control the single-phase socket 12 without opening the housing 1. For the structural principle of the second switch body 61, please refer to Figure 6 and Figure 7 A connecting piece 611 is provided to connect the single-phase segment 22 and the three-phase segment 21 respectively. The second control piece 62 can control whether the two connecting pieces 611 are in contact. Different postures of the second control piece 62 control whether the two connecting pieces 611 are connected. When connected, the single-phase segment 22 is energized and the single-phase socket is energized. When not connected, the single-phase segment 22 is not energized and the single-phase socket is not energized.

[0059] It should be pointed out here that the relevant technology of the single-phase switch 6 is the existing technology, and the principle of the single-phase switch 6 will not be described in detail here. In other embodiments, switches of other structural forms can also be used to control whether the single-phase segment 22 is energized.

[0060] In this embodiment, the single-phase socket includes a two-hole socket 121 and a three-hole socket 122. The two sockets of the two-hole socket 121 are respectively connected to the live wire 2 and the neutral wire 3, and the three sockets of the three-hole socket 122 are respectively connected to the live wire 2, the neutral wire 3 and the ground wire 4.

[0061] The three-hole socket 122 and the three-phase four-hole socket 11 are connected to the same ground wire 4, and the two-hole socket 121 and the three-hole socket 122 are both household sockets.

[0062] In the housing 1 , a first socket 111 is provided corresponding to the three-phase four-hole socket 11 . An external plug is inserted into the first socket 111 from the three-phase four-hole socket 11 to achieve connection with the live wire 2 and the ground wire 4 .

[0063] A second socket 1211 is provided corresponding to the two-hole jack 121 , and an external plug is inserted into the second socket 1211 from the two-hole jack 121 to achieve connection with the live wire 2 and the neutral wire 3 .

[0064] A third socket 1221 is provided corresponding to the three-hole socket 122 , and an external plug is inserted into the third socket 1221 from the three-hole socket 122 to achieve connection with the live wire 2 , the neutral wire 3 and the ground wire 4 .

[0065] Please refer to Figure 3The live wire 2 includes a first live wire 23, a second live wire 24 and a third live wire 25, all of which are arranged inside the shell 1. The four sockets of the three-phase four-hole socket 11 are respectively connected to the first live wire 23, the second live wire 24, the third live wire 25 and the ground wire 4. Any one of the first live wire 23, the second live wire 24 and the third live wire 25 is connected to the single-phase socket to form a connection between one socket of the single-phase socket and the live wire 2.

[0066] The first live wire 23 , the second live wire 24 and the third live wire 25 can all be energized, and the single-phase socket 12 only needs to be connected to any one of the three to achieve connection with the live wire 2 .

[0067] The three-phase four-hole sockets 11 are arranged into multiple groups, and at least one group of three-phase four-hole sockets 11 whose sockets are connected to the second live wire 24 are adjacent to the sockets of the adjacent three-phase four-hole sockets 11 connected to the second live wire 24, or at least one group of three-phase four-hole sockets 11 whose sockets are connected to the first live wire 23 are adjacent to the sockets of the adjacent three-phase four-hole sockets 11 connected to the first live wire 23.

[0068] Each group of three-phase four-hole sockets can correspond to an external connector, and each group of three-phase four-hole sockets has four sockets. Setting at least one group of three-phase four-hole sockets 11 connected to the socket of the second live wire 24 is adjacent to the socket of the adjacent three-phase four-hole socket 11 connected to the second live wire 24, which can realize the forward and reverse function of the socket. In other words, at least two or more groups of three-phase four-hole sockets can realize the forward and reverse function by changing the position of the socket connected to the second live wire 24, such as Figure 4 There are two sets of three-phase four-hole sockets in the middle. There is no need to reconnect the wires. You only need to unplug the plug and plug it into another socket to achieve forward and reverse rotation.

[0069] For the case where at least one group of three-phase four-hole sockets 11 connected to the socket of the first live wire 23 is adjacent to the socket of the adjacent three-phase four-hole socket 11 connected to the first live wire 23, the principle is similar to the above-mentioned principle with the second live wire 24, such as Figure 3 The two three-phase four-hole sockets 11 in the middle are just like this.

[0070] In this embodiment, FireWire 2 is a cable structure, please refer to Figure 3 The ground wire 4 and the neutral wire 3 are also cable structures. The first live wire 23, the second live wire 24, and the third live wire 25 are three cables respectively. The three cables can be connected to the three sockets of one group of three-phase four-hole sockets 11 respectively, and the three sockets of another group of three-phase four-hole sockets 11 can then lead out three new cables for connection.

[0071] The live wire 2 may also be a copper busbar structure, and the live wire 2 is connected to the three-phase four-hole socket 11 via a jumper 7 .

[0072] The first live wire 23, the second live wire 24 and the third live wire 25 are all copper busbar structures and are arranged side by side inside the shell 1. Jumpers 7 are respectively set on the first live wire 23, the second live wire 24 and the third live wire 25 to realize the connection between the live wire 2 and the three sockets of a group of three-phase four-hole sockets 11. For the three sockets of another group of three-phase four-hole sockets 11, another jumper 7 can be set on the same copper busbar structure for connection.

[0073] In this embodiment, since the three-phase four-hole socket 11 and the single-phase socket are arranged on the same socket row, the directions of the live wire 2, the neutral wire 3 and the ground wire 4 need to be reasonably arranged.

[0074] The three-phase four-hole socket 11 is set on one side of the single-phase socket, at least a part of the live wire 2 is set on the side of the three-phase four-hole socket 11 away from the single-phase socket, at least a part of the ground wire 4 is arranged between the three-phase four-hole socket 11 and the single-phase socket, and the neutral wire 3 is set between the live wire 2 and the ground wire 4.

[0075] The power strip switch 5 is located on the same side of the three-phase four-hole socket 11 and the single-phase socket, and the single-phase switch 6 is arranged on the other side of the single-phase socket 12.

[0076] With such a structure, creepage distance and electrical distance can be ensured while conveniently achieving connection with the three-phase four-hole socket 11 and the single-phase socket.

[0077] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
