Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-2, a short-circuit prevention safety socket comprises a socket body 1 with a plurality of jacks, the socket body 1 is respectively provided with a plurality of conductive grooves 2 communicated with the jacks, the inner wall of each conductive groove 2 is connected with an annular liquid storage cover 4, an opening of each annular liquid storage cover 4 is fixedly connected with an elastic conductive ring 5, a fixing plate 3 is horizontally connected in each conductive groove 2, the lower end of each fixing plate 3 is fixedly connected with an elastic air bag 6, a liquid inlet pipe 8 and a liquid outlet pipe 9 are respectively communicated between each elastic air bag 6 and the corresponding annular liquid storage cover 4, a first check valve and a second check valve are respectively arranged in each liquid inlet pipe 8 and each liquid outlet pipe 9, the first check valve only allows gas or liquid in the elastic air bag 6 to enter the annular liquid storage cover 4 through the liquid inlet pipe 8, the second check valve only allows gas or liquid in the annular liquid storage cover 4 to enter the elastic air bag 6 through the liquid outlet pipe 9, the side wall of each liquid discharge pipe 9 is provided with a mounting groove 10, each mounting groove 10 is internally and elastically connected with a movable block 12 through a memory spring 11, each movable block 12 is in sealed sliding connection with the groove wall corresponding to the mounting groove 10, the memory spring 11 can adopt a similar CuZnAl memory alloy spring, the expansion temperature is 65-85 ℃, namely, when the temperature of the memory spring exceeds 85 ℃, the memory spring can contract and deform and can automatically recover to the original state after being lower than the temperature, each annular liquid storage cover 4 is electrically connected with an external power supply connecting terminal through a lead, the lower end of each elastic air bag 6 is fixedly connected with a first permanent magnet 7, and the upper end of each first permanent magnet 7 is an N pole.

In the invention, hydraulic oil is filled in a sealed space formed by each annular liquid storage cover 4 and the corresponding elastic conducting ring 5, the liquid inlet pipe 8, the liquid outlet pipe 9 and the elastic air bag 6, and the hydraulic oil can be No. 46 turbine oil which has the characteristics of insulation and non-conduction and has high ignition point and good heat resistance.

The utility model provides an prevent short circuit safety type plug, includes the plug body 13 that has a plurality of conducting strips, and every conducting strip lower extreme is equal fixedly connected with second permanent magnetism piece 14, and every second permanent magnetism piece 14 lower extreme is the N utmost point.

When the invention is used, in an initial state, one end of the movable block 12, which is far away from the memory spring 11, is pressed against the inner wall of the liquid discharge pipe 9 under the elastic action of the memory spring 11, so that the liquid discharge pipe 9 is in a blocked state;

when electricity is needed to be taken, the conducting plate of the plug body 13 is inserted into the corresponding conducting groove 2 through the jack, the elastic conducting ring 5 is extruded and deformed by the conducting plate, the elastic conducting ring 5 is in contact with the conducting plate, the circuit is conducted, and the electrical appliance can normally work, and it is worth noting that although repulsion force exists between the first permanent magnet 7 and the second permanent magnet 14 at the moment, the elastic air bag 6 keeps the original shape because the drain pipe 9 is blocked, and the elastic conducting ring 5 always exerts elastic force on the conducting plate because hydraulic oil in the annular liquid storage cover 4 and the elastic conducting ring 5 cannot flow out, so that the plug body 13 and the socket body 1 can keep a stable connection relationship;

when a circuit is short-circuited or overloaded to cause the temperature between the conducting strip and the elastic conducting ring 5 to rise rapidly, the temperature inside the conducting groove 2 rises rapidly and exceeds the deformation temperature of the memory spring 11, the memory spring 11 contracts and drives the movable block 12 to contract and enter the mounting groove 10, the liquid discharge pipe 9 can communicate the annular liquid storage cover 4 with the elastic air bag 6, the elastic air bag 6 is stretched under the action of the repulsive force between the first permanent magnet 7 and the second permanent magnet 14, hydraulic oil in the annular liquid storage cover 4 enters the elastic air bag 6 through the liquid discharge pipe 9, the elastic conducting ring 5 is changed from a protrusion to a recess, meanwhile, the elastic conducting ring 5 is separated from the conducting strip, the circuit is disconnected, an electric appliance stops working, and therefore an accident situation is avoided;
