Preferably, the top of the surface of the shell is fixedly connected with a fixed block, and the top of the shell is designed to be flat.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses a cooperation of casing, light current wire, forceful electric power wire, thermistor and thermal fuse is used, can cut off the power supply to equipment automatically when taking place danger, makes equipment stop heating, and protective apparatus does not receive the damage, and it is not right to have solved the signal that current temperature sensor fed back to the control panel under the high temperature condition, causes equipment to continue to heat, and then damages equipment, arouses the conflagration, causes the problem of incident.

2. The utility model discloses a set up first insulating cover, can make the better insulation of thermistor, through setting up the insulating cover of second, the better insulation of messenger's thermal fuse that can be better, through setting up the fixed block, can fix the casing, through setting up flat mouthful of casing, can prevent to have enough to meet the need the inside components and parts of casing when using and shift.
