The second accommodating groove 102 is disposed directly below the first accommodating groove 101 and communicates with the first accommodating groove 101. The upper end of the binding post 103 is arranged in the first accommodating groove 101, the lower end of the binding post 103 is fixedly connected with a transmission shaft 104, and the binding post 103 is rotatably connected with two opposite sides of the second accommodating groove 102 through the transmission shaft 104, so that the binding post 103 can be turned over and accommodated in the first accommodating groove 101.
The inside of the post 103 is provided with two or three electrode contacts 105 of different polarities, and preferably the number of electrode contacts 105 is two. In this embodiment, the electrode contact 105 is embedded inside the post 103, and the connection structure is more stable. The post 103 has a rectangular parallelepiped shape so that the electrode contact 105 provided inside the post 103 is not easily touched. The inside of the binding post 103 is also provided with a clamping groove 106, and the clamping groove 106 is arranged between the two electrode contacts 105, so that the clamping groove 106 effectively isolates the two electrode contacts 105, the creepage distance between the two electrode contacts 105 is increased, and the situation that the two electrode contacts 105 are dangerous due to too small separation distance is avoided. The electrode contact 105 is connected with a power supply for obtaining electric energy, an overcurrent protector is arranged between the electrode contact 105 and the power supply, and when the current of an electric appliance is overlarge, the overcurrent protector can automatically disconnect the connection between the electrode contact 105 and the power supply, so that the use safety is improved.
As shown in fig. 3, the driving module 2 is disposed in the housing 109 and is used for driving the transmission shaft 104 to rotate, and includes a driving motor 201, an electromagnetic brake 202 and a controller 203. The rotating shaft 204 of the driving motor 201 penetrates through the electromagnetic brake 202 and is in transmission connection with the transmission shaft 104. The electromagnetic brake 202 can effectively brake so that the rotation shaft 204 cannot rotate when the rotation shaft stops, and the binding post 103 is ensured to be kept in a vertical state in an initial state. Preferably, the rotation shaft 204 is connected with the transmission shaft 104 through gear transmission, so that stability of transmission connection is improved, and in addition, the device has the advantages of simple structure and low cost.

One end of the power line 5 is disposed in the connector 4 and is correspondingly connected with the metal contact plate 401 for transmitting electric energy. The power cord 5 can apply pressure to the inside of the post 103 through the connector 4.
As shown in fig. 2, the pressure sensor 3 is provided inside the terminal 103 and connected to the controller 203 for detecting the pressure between the terminal 103 and the connector 4. If the pressure is greater than the safety pressure preset by the controller 203, the controller 203 controls the brake element of the electromagnetic brake 202 to be separated from the rotating shaft 204 of the driving motor 201, and simultaneously, the controller 203 controls the driving motor 201 to rotate forward and drives the binding post 103 to turn over 90 degrees outwards, so that the connector 4 is separated from the binding post 103 under the drive of the power line 5. When the binding post 103 turns 90 degrees, the controller 203 controls the driving motor 201 to rotate reversely and drives the binding post 103 to reset; when the binding post 103 is reset, the controller 203 controls the driving motor 201 to stop, and at the same time, the controller 203 controls the brake to be connected with the rotating shaft 204, so as to fix the rotating shaft 204.
As shown in fig. 4, the bottom surface of the second accommodating groove 102 is provided with the same number of support columns 108 as the electrode contacts 105, and the top ends of the support columns 108 are provided with contact structures correspondingly connected with a power supply; in an initial state, the contact structure is connected to the electrode contact 105, and when the terminal 103 is flipped outwards, the electrode contact 105 is away from the contact structure. By means of the arrangement, when the binding post 103 is turned over, the connection between the electrode contact 105 and a power supply is automatically disconnected, and therefore the use safety is greatly improved. For safety, a protective shield may be disposed outside the second receiving groove 102 to prevent the electrode contact 105 and the contact structure from being exposed to the accessible region through the second receiving groove 102. The protective baffle cannot be set higher than the second accommodating groove 102, otherwise the overturning of the binding post 103 is affected.
As shown in fig. 4, the first accommodating groove 101 is provided with elastic columns 107 having the same number as the electrode contacts 105, the elastic columns 107 are horizontally arranged and are opposite to the electrode contacts 105, and when the connector 4 is sleeved on the binding post 103, the elastic columns 107 press the connector 4 to enhance the connection stability between the electrode contacts 105 and the metal contact pieces 401. In this way, when the connector 4 is connected with the power supply seat 1, a certain extrusion force exists between the connector 4 and the power supply seat 1, so that the connection stability of the electrode contact 105 and the metal contact piece 401 is increased.
A hanging type power supply connection combination is composed of a plurality of arbitrary hanging type power supply connection devices. The arrangement is convenient for hooking more electric appliances, thereby improving the space utilization rate of the power supply base 1. In this embodiment, a hanging power connection assembly is formed by four hanging power connection devices, wherein four power sockets 1 are transversely assembled and connected in pairs.
In another embodiment, a power connection assembly of a hanging type is composed of four power connection devices of a hanging type, wherein four power sockets 1 are longitudinally assembled and connected in pairs.
The power supply seat 1 and the connector 4 are easier to separate and safer in the use process, and when the connector 4 is separated from the power supply seat 1, the binding post 103 can be automatically reset, so that the invention is very convenient and practical; in addition, the binding post 103 of the invention can be sleeved with a plurality of connectors 4 at the same time, so as to supply power to a plurality of electric appliances at the same time; because the hanging mode is adopted, the gaps among the connectors 4 are small, so that the space of the power supply base 1 can be greatly saved.
The foregoing description is directed to the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the invention, and all equivalent changes or modifications made under the technical spirit of the present invention should be construed to fall within the scope of the present invention.
