Description

Plug-in door structure with error-proofing function, power supply plug-in assembly and power supply device

Technical Field

The utility model belongs to the technical field of electrical equipment, and particularly relates to a plug-in door structure with an error proofing function, a power supply plug-in assembly and a power supply device.

Background

Plugs and sockets are indispensable components in electrical equipment. The plug is a key part for connecting electrical equipment with a power supply system, and electric connection is established through contact points between the plug and the socket, so that electric energy transmission is realized. The socket is a power plug connector and is used as an interface of a power supply to provide safe and reliable contact points so that the electrical equipment can receive power supply. The connection relationship and reliability of the plug and the socket are critical to the safety, performance and user experience of the electrical equipment.

In some devices, the power interface is often plugged directly in an exposed form for ease of operation, or an interface with door panel protection is used. When using an interface with door panel protection, a key is required to open the protection door for the plugging operation. However, there are some safety hazards and drawbacks in this case if the key is pulled out in a state where the protection door is not effectively locked.

First, when the protective door is not effectively locked, the power supply interface is in an open state for a long time. This may lead to exposure of the power supply of the electrical device to the external environment, with safety risks of electric shock and short circuit. For example, accidental touch may cause electrocution injury, or dust, liquid, etc. entering the interface may cause malfunction or damage to the device.

Second, if the key can be pulled out without the protective door effectively locked, the power interface will be left uncontrolled. This means that anyone can plug and unplug the device at will, possibly resulting in an unexpected power loss, malfunction or unauthorized access. This may present risks to the proper functioning of the device, the security of the data, and the security of the working environment.

In summary, in the prior art, when the protective door is not effectively locked, the key is pulled out to leave, which brings potential safety hazards and defects, and the safety of the electrical equipment is possibly threatened, and the safety of the working environment and data is possibly at risk. Therefore, there is a continuing need for improvements over existing electrical plug structures.

Further, the limiting component is a limiting plate which is close to the lock tongue, the limiting plate is arranged on the inner side of the door plate, and in the door plate opening and closing process, the lower plate surface of the limiting plate blocks the lock tongue from swinging to a locking position.

In this embodiment, specifically, the limiting component is an upper shell plate, and in the door panel opening and closing process, the lower plate surface of the upper shell plate blocks the lock tongue from swinging to the locking position, and the upper shell plate is provided with lock holes 1-21, which are holes penetrating the upper shell plate, and in the door panel closing state, the lock tongue penetrates through the lock holes and is in the locking position. Namely, under the condition that the self-locking position of the lock tongue is not vertical through rotating, namely, the front section of the lock tongue is retracted into the inner side of the upper shell plate, the combination effect of the lock tongue and the lock hole is disappeared, the door plate can be opened in a sideslip mode, after the sideslip action of the door plate begins, the outer end part of the lock tongue is blocked by the upper shell plate, so that the lock tongue in the non-locking state is always physically limited and cannot return to the locking position, and then the key is always unable to be pulled out from the self-locking body in the state that the door plate is opened. In order to enable the rotary lock tongue to extend and retract, the lock hole is designed as a corresponding long hole.

In this embodiment, the side panels are provided with side slits for the door panels to pass laterally. The side of the panel corresponding to the seam is provided with an extension plate part extending to the side. The extension plate part can completely shield the panel which is drawn out laterally, the panel is provided with the mounting hole, and after the assembly is mounted on the power supply disassembling device, the panel serving as the outer side shell can complete the sealing of the door plate on the inner side of the box body of the shape body.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
