Abstract

The invention discloses an overheating and overcurrent protection plug. The plug comprises a connecting plate and a rotating box, wherein an annular rotating groove is formed in a side wall of the connecting plate, a rotating ring slidably connected with an inner wall of the rotating groove is fixed to the side wall of the rotating box, two symmetrically-arranged power connection boxes are fixed to the side, close to the rotating box, of the connecting plate, two power connection plates connected with the interiors of the two power connection boxes correspondingly are inserted into the side, away from the rotating box, of the connecting plate in a penetrating mode, expansion grooves are formed in side walls of the two power connection plates correspondingly, and clamping blocks are connected with inner walls of the two expansion grooves through connecting springs correspondingly. The plug is advantaged in that clamping block are arranged, after the plug is powered on, the electrorheological fluid in the expansion groove is solidified and expanded, so the clamping block is pushed by the electrorheological fluid to move out of the expansion groove, the clamping block limits movementof the power connection plate, the power connection plate cannot be directly separated from the socket, stable combination of the plug and the socket is guaranteed in the power connection process, theplug is prevented from being easily separated from the socket by external force, and power supply stability is guaranteed.

Description

technical field [0001] The invention relates to the technical field of plugs, in particular to an overheating and overcurrent protection plug. Background technique [0002] The connectors of general electronic products and the pins of electrical appliances are called plugs, which are usually used in conjunction with sockets. They are commonly used electrical tools for modern electronic equipment and are widely used in various industries; [0003] The existing plugs generally only have the function of connecting electricity, and cannot protect the power lines, and they themselves will generate heat after long-term use, and generally have poor heat dissipation capabilities, and the internal heat is easy to accumulate, so that the wiring near the plug It is prone to short-circuit faults, causing line damage, and cannot protect the line when the line is overcurrent, and the safety of the line cannot be guaranteed. Therefore, there is an urgent need for a plug that can provide pr...
