Description

Technical Field

[0001] The utility model relates to the technical field of switching power supplies, and particularly relates to a switching power supply provided with an electric shock prevention structure. Background Technique

[0002] A switching power supply is a power converter that controls the power output by quickly switching a switching element (such as a transistor). Its working principle is to convert the input alternating current or direct current into the required direct current voltage, and it has the advantages of high efficiency, small volume, and light weight;

[0003] In the prior art, when a staff member uses a switching power supply, if the staff member accidentally touches the switching power supply, an electric shock phenomenon is likely to occur. When the voltage is relatively high, the staff member's body is easily damaged, and the safety of the staff member cannot be guaranteed;

[0004] In order to overcome the above deficiencies, a Chinese patent of the prior art (publication number CN211320405U) discloses a switching power supply that can prevent electric shock. A power cord is fixedly connected to the left side of the socket. The top and bottom of the left side of the switching power supply housing are both fixedly connected with connecting seats, and a groove is opened in the inner cavity of the connecting seat. In the utility model, when the sleeve plate moves to the left, the sleeve plate drives the connecting rod to move, the connecting rod drives the moving plate to slide on the surface of the guiding column, and at the same time, the movement of the moving plate drives the limiting rod to slide inside the limiting groove. Through the movement of the moving plate, the clamping spring deforms. Subsequently, the socket is inserted into the sleeve plate, and the sleeve plate is released. Under the restoration of the deformation of the clamping spring, the plug body is inserted into the switching power supply housing, achieving the advantage of preventing electric shock and solving the problem that the existing switching power supply does not have the function of preventing electric shock during use;

[0005] Although the prior art can overcome the above-mentioned deficiencies, there are still other problems during its operation. For example, when using the switching power supply to connect with a circuit, if the circuit is bent and folded, it will affect the stability of the circuit and is not conducive to the wiring connection of the staff.

[0012] Furthermore, an elevating tooth plate is arranged above the connecting conductor. The elevating tooth plate is fixedly installed at the lower end of the insulating rod. A return spring is arranged between the elevating tooth plate and the circular shell.

[0013] Furthermore, a piston rod is fixedly installed at the upper end of the elevating tooth plate. A sleeve is fixedly installed on the inner wall of the circular shell. The upper end of the piston rod is in contact with the inner wall of the circular shell.

[0034] In the embodiment, before using the device, the connecting wire 4 is installed at the upper end of the conductive tooth plate 9 through the installation tooth plate 10.
