Description

Technical Field

[0001] The utility model relates to the field of plugs, in particular to a waterproof and dustproof plug. Background Art

[0002] When the existing plugs are in use, it is difficult for the plugs and sockets to be tightly connected together, and there will be gaps. External moisture can easily enter the inside of the plugs and sockets through the gaps, causing short circuits and other situations that affect normal use. In addition, after the plugs and sockets are connected, they have no corresponding locking protection and are easily accidentally detached by collision or pulling.

[0003] For this reason, it is necessary to invent a waterproof and dustproof plug. Summary of the invention

[0004] To this end, the utility model provides a waterproof and dustproof plug to solve the problems in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waterproof and dustproof plug, comprising a shell and a plug embedded in the shell, a cable is further arranged at the bottom of the shell, the cable extends into the shell and is connected to the plug, a plurality of small male hardware, large male hardware and long male hardware are embedded and installed inside the plug, a lock cover is arranged at the top of the plug, a button is embedded inside the lock cover, the button and the lock cover are movably connected through a rotating shaft, a spring is embedded inside the lock cover, the spring abuts against the inner wall of the bottom of the button, and a buckle is arranged on one side of the lock cover;

[0006] A socket that is plugged into one side of the plug is also provided, and a number of small female hardware, large female hardware and long female hardware are provided inside the socket. A circular ring buckle is provided at the end of the long female hardware, and a crown spring is embedded in the long female hardware. A support ring is also provided on the socket, and a dust cover is fixedly connected to the bottom of the support ring. A card slot is provided at the top of the socket corresponding to the lock cover position of the plug.

[0007] Preferably, a waterproof ring is provided at the connection between the plug and the socket.

[0008] Preferably, the support ring and the dust cover are integrally formed and made of rubber material.

[0009] Preferably, the inner diameter of the dust cover matches the outer diameter of the socket.

[0010] The beneficial effects of the utility model are:

[0011] The utility model adopts the design of the waterproof ring. When the plug and the socket are plugged in, the waterproof ring is squeezed by the plug and the socket, so that the waterproof ring fits the plug and the socket more closely, thereby effectively protecting the inside of the plug and the socket to prevent the entry of external moisture. When the plug and the socket are not plugged in, the dust cover can be covered on the socket to prevent external dust and impurities from entering the socket to contaminate the internal electronic components, thereby increasing the service life of the socket. The button buckle can also be matched and engaged with the socket slot to further ensure the stability of the plug and socket connection and prevent accidental falling off.
