Electrical system socket and plug capable of preventing mistaken pulling and convenient to pull out

Abstract

An electrical system socket and plug capable of preventing mistaken pulling and convenient to pull out relates to the technical field of rail transit electrical systems, and comprises a socket, the inner bottom wall of the socket is fixedly connected with conducting strips, the inner bottom of the socket is provided with guide grooves, the bottom of the socket is provided with hydraulic grooves, and the inner walls of the hydraulic grooves are movably connected with clamping blocks plugged with the guide grooves. According to the electrical system socket and plug capable of preventing mistaken pulling and facilitating pulling out, through cooperative use of the electro-magnetic device and the clamping blocks, in the initial state, the clamping block is contracted in the hydraulic groove, the piston block is located at the top of the hydraulic groove under the action of the first spring, and when the plug is connected with the socket in an inserted mode and plugging is completed, a circuit of the electro-magnetic device is just connected, the piston block moves downwards under the action of the electro-magnetic device, and the clamping block extends out of the hydraulic groove to be clamped with the clamping groove according to the hydraulic principle, so that the plug is difficult to pull out, the pull-out prevention effect is achieved, the plug is prevented from being knocked off accidentally, and stable output of electric power is ensured.

Description

Technical field[0001]The present invention relates to the technical field of rail transit electrical systems, in particular a socket and plug for an electrical system that is easy to remove.Background technique[0002]In the electrical system of rail transit, the socket is a more important part. The passengers on the road will often use the socket to charge their mobile phones, computers, or tablets, so that the equipment is not electricity, will affect their work.[0003]Most of the current sockets are directly inserted. There is no limit device, so when the plug is plugged in, if there is an external force, it is very easy to fall off, resulting in less stable charging, which may cause insufficient equipment to charge, affect the later use, And now the plug is difficult to pull out from the outlet, the force needs to be large, more troublesome.[0004]Therefore, we propose an anti-aircraft and easy-to-pull electrical system socket and plug to solve the above problems, and use the electr...

Problems solved by technology

[0002] In the electrical system of rail transit, the socket is a relatively important part. Passengers on the road often use the socket to charge their mobile phones, computers or tablets, so as to prevent the equipment from running out of power and affect their work.

[0003] Most of the current sockets are directly plugged in, and there is no limit device, so when the plug is plugged in, if there is an external force, it is easy to fall off, resulting in unstable charging, which may cause insufficient charging of the device and affect later use. Moreover, the current plug is difficult to pull out from the socket, and the force required is relatively large, which is troublesome.
