Description

Technical Field

[0001] The utility model relates to the technical field of plugs, in particular to a plug which is easy to plug and unplug. Background Art

[0002] A plug is the part of the power cord with a male pin. Its full name is a plug connector. Household AC power plugs and outlets have a male connector with a protruding rod or copper plate that physically inserts into a female power outlet with a slot or recess. Ease of insertion and removal is a key function of the plug.

[0003] For example, the Chinese patent publication number CN216529621U, "A plug that is easy to plug and unplug," includes a plug body, wherein the plug body is provided with a conductive sheet, a conductive sheet fixing block, and a wire connecting block; the conductive sheet is mounted below the conductive sheet fixing block, and the conductive sheet is vertically connected to the conductive sheet fixing block; the conductive sheet fixing block is mounted below the wire connecting block, and the conductive sheet fixing block is vertically connected to the wire connecting block; the wire is mounted above the wire connecting block, and the wire is vertically connected to the wire connecting block; the conductive sheet fixing block is made of insulating material, and the conductive sheet fixing block is vertically connected to the wire connecting block. The connection of the connecting block is concave in design, which increases resistance and facilitates plugging and unplugging. The wire connecting block is made of an insulating material with good toughness, and a concave groove is provided on the outer surface of the wire connecting block. The wire connecting block is made of an insulating material with good toughness and the design of the concave groove on the outer surface can make the plug better adapt to different angles during use, and at the same time protect the wires during plugging and unplugging, thereby extending the service life of the plug. Two conductive sheets are provided, which are installed in parallel below the conductive sheet fixing block. A heat dissipation hole is provided on the front side of the conductive sheet fixing block. The heat dissipation hole is designed to allow the heat generated by the plug during operation to be dissipated in time.

[0004] Although the above-mentioned prior art can realize the plugging and unplugging of the plug, in actual use, on the one hand, the plug is difficult to be unplugged from the socket. Usually, when the plug needs to be unplugged, the user needs to hold the socket body and pull it outward, which requires a certain amount of force to unplug the plug, making the plug unplugging inconvenient. On the other hand, if the plug is not used for a long time, the pins are prone to oxidation and corrosion. If the plug is not used for a long time, the pins are directly in contact with dust and moisture in the air, resulting in dust and moisture in the air adhering to the pins and easily oxidizing and corroding the pins, thereby affecting the conductive performance of the plug and the smoothness of plugging and unplugging. Therefore, it does not meet the existing needs. In this regard, we propose a plug that is easy to plug and unplug. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model facilitates the retraction of the plug pin into the inside of the plug box by using the fixing rod and the pressing rod. When the plug needs to be unplugged, the user presses the pressing rod, and the pressing rod moves downward in the sliding cavity. At the same time, the fixing seat squeezes the second spring until one end of the pressing rod contacts and squeezes the fixing rod. The pressing rod continues to move, and the fixing rod is disengaged from the fixing hole and squeezed back into the telescopic cavity through the pressing rod. At this time, the first spring fixed on the fixing rod is in a compressed state, and the third spring is reset. The reset of the third spring drives the plug pin to move outward inside the socket until the pin moves to a suitable position. At this time, the plug is removed from the socket, which simplifies the steps of removing the plug, thereby making plugging and unplugging more convenient.

[0015] 2. The utility model uses the third spring and the limit plate to keep the pin inside the plug box when the plug is not in use. When the pin is not in use, the user presses the pressing rod, and the third spring resets. During the reset process of the third spring, the mounting plate and the pin are driven to move toward the inside of the plug box. At the same time, the limit plate slides inside the slide groove until the pin moves to a suitable position. At this time, the third spring is in a normal state, and a small part of the pin is exposed outside the plug box, preventing dust and moisture in the air from oxidizing and corroding the pin when the plug is not in use, thereby extending the service life of the pin.

[0016] 3. The utility model is provided with a rubber pad, which can prevent the user's hands from coming into contact with the pins when using the plug. When the plug is inserted into the socket, the pin is first pulled to move outward inside the plug box until the fixing rod is reinserted into the fixing hole. At the same time, the third spring is in a stretched state. At this time, when the pin is inserted into the socket, the rubber pad shields the pin during the insertion process, preventing the user's hands from coming into contact with the pin, thereby reducing the risk of electric shock to the user.
