Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the description of the present invention, it should be noted that, unless explicitly stated or limited otherwise, the terms "mounted," "disposed," and "connected" are to be construed broadly, for example, the term "connected" may be a fixed connection, a detachable connection, or an integral connection; either directly or indirectly through intervening media, either internally or in any combination thereof. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

One embodiment of the outlet tandem system of the present invention, as shown in fig. 1, includes a power supply line and at least one power strip 4.

As shown in fig. 14 to 15, the power supply line includes a standard plug, a power plug line 1, and a patch plug, and the patch plug is connected to the standard plug through the power plug line 1, wherein the standard plug may be a american standard plug, an european standard plug, a national standard plug, etc., but is not limited to the above-mentioned kind of standard plug. As shown in fig. 7, in the present series system, since the power supply line is directly connected to the power supply, the power supply can be directly connected to an indoor or outdoor power outlet through a standard plug.

As shown in fig. 5, adapter connectors are provided at both ends of the power strip 4 to be connected to power supply lines via adapter plugs, so as to enable power to be taken out, and a plurality of independent power transmission circuits are provided inside the power strip 4, wherein at least one independent power transmission circuit can be used to supply power to each socket on the power strip 4, and at least one independent power transmission circuit can be used to implement power transfer.
