[0002] As a common electrical component, power strips are widely used in production and life. The rotating plug has a rotatable function and can rotate within a certain angle range to adapt to different usage scenarios and needs.

[0003] Compared with traditional socket strips, the rotating conversion plug can adjust the plug angle when operating the device to avoid interference between the plug and the device or other objects, while ensuring stable power supply for the device. The rotating plug can rotate around a certain axis and can easily adapt to the power connection requirements at different angles. Since each plug of the rotating plug can rotate independently, collision and obstruction between multiple plugs can be avoided, improving the efficiency of the socket strip.

[0004] In the prior art, the rotary plug cannot be fixed in time after the angle is adjusted, resulting in rotation after connection, affecting the stability of power connection; the rotary plug has the problem of inconvenient operation in design, and the rotation of some plugs requires the use of specific operation methods and strength, which may be difficult for users to master during use; in the non-working state, if the metal contacts of the plug and socket are exposed, the human body or conductive objects can easily come into contact with the live parts, causing electric shock accidents.

[0059] A turn indicator and an indicator light 40 are provided on the plug shell 3 and adjacent to each upper panel 30. The turn indicator is provided to facilitate the indication of the rotation direction of the index shell 4. When the plug module is in a non-powered state, an indicator light 40 is off and otherwise it is on.

[0060] The working principle of the present invention is: when the plug is working, the power distribution terminal and the connector 10 are set so that the power cord 11 can rotate freely in multiple directions, thereby reducing the breakage and breakage rate of the power cord 11 at the connection with the seat plate 1 when supplying power.

At the same time, by realizing the splicing function of the plug, the rapid disassembly and installation of related components in the device are facilitated, thereby reducing the use and maintenance costs of the plug. When the strip module is not in use, under the action of the third torsion spring 32, the socket 31 on the upper panel 30 and the socket 31 on the lower panel 29 are staggered. The staggered setting is used to seal and protect the sockets 31 on the lower panel 29. The sealing protection makes it easy for foreign objects or water to enter the sockets 31 on the lower panel 29. When the power strip module needs to be used, the plug is first aligned with the positions of the sockets 31 on the upper panel 30. Then, the plug drives the upper panel 30 to rotate a set angle and aligns the positions of the sockets 31 on the upper panel 30 with the sockets 31 on the lower panel 29, thereby realizing the protective installation of the plug. When the power strip module is not in use, the power connection copper sheet 39 and the power connection bead 38 are staggered. After the plug is inserted into the lower panel 29, the user drives the indexing shell 4 to rotate 90°, and then the two power connection copper sheets 39 are electrically connected to the two power connection beads 38 respectively, thereby realizing the power supply conduction of the circuit elements in the indexing shell 4. During the rotation of the indexing shell 4, the clamping screw 7 rotates, thereby realizing the clamping of the plug on the plug shell 3, thereby reducing the detachment rate of the plug after insertion.
