The plug includes a main body, a leakage protection module fixedly connected to one side of the top of the main body, a leakage protection element and a control module inside the leakage protection module, a rubber sleeve fixedly connected to the outside of the main body, annular openings at both the top and bottom of the rubber sleeve, a connecting ring fixedly connected to the annular opening, a soft rubber layer fixedly connected between the connecting rings, a spring strip fixedly connected to one side of the connecting ring inside the soft rubber layer, a protective cloth sleeve fixedly connected to the top of one side of the inner wall of the rubber sleeve, several foam particles inside the protective cloth sleeve, several magnetic balls fixedly connected to one end of the protective cloth sleeve, and a PVC track zipper fixedly connected to the outside of one side of the rubber sleeve. This utility model improves the protection capability against external impacts during device transportation by using a retractable and extendable protective cloth sleeve. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing power plugs are usually used with power bases. However, due to their small size, existing power plugs generally do not have overload and short circuit protection switches inside. This can lead to fires and other hazards when used under overload or short circuit conditions, which can affect safety. Therefore, protective mechanisms are needed when using power plugs to prevent the dangers of short circuits and overloads.

[0005] Therefore, a power plug with leakage protection structure is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a power plug with a leakage protection structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a power plug with a leakage protection structure, including a control motherboard, a protective mechanism fixedly connected to the top of the control motherboard, the protective mechanism including a base plate, a support foot fixedly connected to the top of the base plate, a switch connected to the top of the support foot via a rotating shaft, an insulating head fixedly connected to one end of the switch, a block fixedly connected to the top of the base plate, and a first spring fixedly connected to the upper end of the base plate;

[0008] A support block is fixedly connected to the top of the base plate. A pressure plate is connected to the upper end of the support block via a rotating shaft. A fixing rope is fixedly connected to one end of the pressure plate. The base plate is fixedly installed on the top of the control main board.

[0009] Preferably, a pin base is fixedly connected to the bottom of the control motherboard, a connection port is provided on the top of the pin base, a fire wire pin is fixedly connected to the outer wall of the control motherboard, and a retraction mechanism is provided inside the pin base.

[0010] Preferably, the switch and the connecting block are connected by a movable locking connection, and the connecting block and the fixing rope are connected by a fixed connection.

[0011] Preferably, the pressure plate is disposed at the upper end of the first spring, and the first spring is in a compressed state.

[0012] Preferably, the retraction mechanism includes a grounding pin, and a fixing block is fixedly connected to the outer wall of the grounding pin, the fixing block penetrating the outer wall of the pin base.

[0013] Preferably, a slider is fixedly connected to the outer wall of the grounding pin, and the slider slides on the inner wall of the pin base.

[0014] Preferably, a second spring is fixedly connected to one end of the right side of the grounding pin, and the second spring is fixedly installed inside the pin base.

[0015] Preferably, a locking hole is provided at the upper end of the grounding pin, and a locking block is movably connected inside the locking hole.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. Compared with existing technologies, this power plug with leakage protection structure is easily protected by a protective mechanism. During use, the switch is connected with the connector to supply power. When a short circuit or overload occurs, the connector will heat up and reach high temperature. Then the connector will burn through the fixing rope. At this time, the first spring will be released from the restraint of the pressure plate and pop out to push the insulating head and open the insulating head. At this time, the switch is disconnected from the connector, thus cutting off the power and preventing danger from continued use. This method can better protect the safety of users and avoid the risk of fire during use.

[0018] 2. Compared with the existing technology, the power plug with leakage protection structure is easy to extend and retract through the retraction mechanism. When encountering a three-hole socket, the locking block can be pressed and inserted into the locking hole to fix the ground wire plug. Then the fixing block is inserted into the socket to connect with the ground wire, which is safer to use and improves the safety of use. When encountering a two-hole socket, the fixing block will be squeezed inward and retracted without affecting the use. Attached Figure Description

[0034] In a preferred embodiment, the retraction mechanism 6 includes a ground wire plug 601, and a fixing block 602 is fixedly connected to the outer wall of the ground wire plug 601. The fixing block 602 penetrates the outer wall of the plug base 3.
