Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1-6, an automatic power-off overheat-preventing socket comprises a casing 1, two power receiving cavities 2 are arranged in the casing 1, two U-shaped tubes 3 arranged side by side are arranged in the power receiving cavities 2, specifically, the U-shaped tubes 3 are made of insulating ceramics, each U-shaped tube 3 comprises an arc-shaped tube 4, two ends of each arc-shaped tube 4 are fixedly connected with a first straight tube 5 and a second straight tube 6 respectively, a temperature control box 7 is fixedly connected to the inner bottom surface of each power receiving cavity 2, mercury 8 is filled in each temperature control box 7, the lower ends of the two first straight tubes 5 are fixedly connected and communicated with the temperature control box 7, and each first straight tube 5 is made of insulating materials such as insulating ceramics, so that the socket has good insulating capability and good heat dissipation effect.
A first conducting ring 9 is embedded in the middle of the first straight pipe 5, a second conducting ring 10 is embedded at the lower end of the first straight pipe 5, a conducting pipe 11 is fixedly connected on the outer side wall of the first conducting ring 9 of one first straight pipe 5, a conducting rod 12 is fixedly connected on the outer side wall of the first conducting ring 9 of the other first straight pipe 5, a fixed elastic sheet is fixedly connected in the conducting pipe 11, a jack 13 corresponding to the conducting pipe 11 is arranged on the side wall of the shell 1, a connecting terminal 14 is fixedly connected at one end of the conducting rod 12 far away from the first conducting ring 9, a conducting post 15 is slidably connected in the first straight pipe 5, an insulating layer 16 is fixedly connected at the lower end of the conducting post 15, the insulating layer 16 can be made of insulating ceramic materials, the weight of the insulating ceramic materials can be ignored, sliding posts 17 are slidably and hermetically connected in the second, it should be noted that the weight of the weight block 18 and the two sliding columns 1 is the same as the weight of the two conductive columns 15.
In this embodiment, when a user uses a high-power electrical appliance (such as a blower, a heater, an electric water heater, etc.) for a long time, when the user uses the electrical appliance for a long time, the socket and the plug generate heat seriously due to overlong use time or forgets to turn off the electrical appliance manually, at this time, the mercury 8 expands due to heating and pushes the two conductive posts 15 to move upwards, so that the counterweight block 18 moves downwards, and when the insulating layer 16 moves to the position above the second conductive ring 10, the circuit is disconnected, the electrical appliance stops working, and an accident caused by overuse is avoided; when the circuit is disconnected, the mercury 8 in the temperature control box 7 naturally dissipates heat, and as the temperature of the mercury 8 decreases, the insulating layer 16 gradually moves to the position below the second conductive ring 10, so that the circuit is conducted again, and normal use can be continued.
