Firm-connection and anti-electric shock power supply device

Abstract

The invention discloses a firm-connection and anti-electric shock power supply device, which comprises a socket body and a plug body, and is characterized in that the socket body is internally provided with a first mounting cavity, a second mounting cavity and a slot in sequence from back to front, the cross section of the first mounting cavity is approximately U-shaped in a top view, and is square in a side view, and the second mounting cavity is a rectangular cavity; and two jacks communicated with the second mounting cavity and the slot are symmetrically formed in the socket body, a motor is fixedly embedded in the middle of the inner wall of the rear side of the first mounting cavity, a first screw and a second screw are fixedly connected to the output end of the motor in sequence, thefirst screw and the second screw are located in the first mounting cavity and the second mounting cavity respectively, the thread turning direction of the first screw is opposite to that of the second screw, and the thread pitch of the first screw is larger than that of the second screw. The device has the advantages that the socket is high in safety and is not affected by external force, connection between the socket body and the plug body is guaranteed, and power utilization of electric appliances is not interrupted.

Description

technical field [0001] The invention relates to the technical field of power supply devices, in particular to a power supply device with firm connection and electric shock protection. Background technique [0002] The existing power supply device is mainly powered by plugs and sockets. However, since the power supply part of the socket is exposed to the air, children or people with mental disabilities may use sharp and conductive rods to insert them out of curiosity. The situation of the socket leads to the risk of electric shock. In addition, after the plug and the socket are connected, the connection between the two is limited, and it is very easy to be separated under the influence of external forces such as pulling and dragging, resulting in interruption of the connection and affecting The use of electrical appliances. [0003] In order to solve the above problems, we propose a power supply device with strong connection and electric shock protection. Contents of the i...
