Fixing board in temperature sensor

Abstract

The invention provides a fixing board in a temperature sensor. The fixing board is stable in structure and facilitates the folding of the connecting line at the lower opening of the temperature sensor. The fixing board includes a circular plate-shaped main body, the edges of the two sides of the circular plate-shaped main body are provided with a first hollow part and a second hollow part for installing the hot-melt fuse connecting line, the circular plate-shaped main body is provided with a ground wire installing hole and a third hollow part for fixing the connecting line of a thermistor, the edge of the third hollow part is provided with a claw vertically overhanging toward the circular plate-shaped main body, a straight line where the first hollow part and the second hollow part are arranged forms a cross shape with a straight line where the ground wire installing hole and the third hollow part are arranged, and the two sides of the ground wire installing hole are provided with a first hot-melt fuse through hole and a second hot-melt fuse through hole for installing the hot-melt fuse connecting line.

Description

technical field [0001] The invention relates to the technical field of spare parts of small household appliances, in particular to a fixing plate in a temperature sensor. Background technique [0002] Most of the existing electric cooker temperature sensors are temperature sensors using thermistors, and double thermal fuses are arranged in the temperature sensors. In order to fix the connecting wire of the thermistor and the connecting wire of the thermal fuse, a fixing plate bracket 2 is usually arranged in the temperature sensor, and the structure of the fixing plate bracket is as follows figure 1 shown. Among them, the hollow part 21 is used to fix the two connection wires of the double thermal fuse at the same time, the hollow part 22 and the claw 24 are used to fix the connection wire of the thermistor, and the ground wire installation hole 23 is used to connect the ground wire with the screw and other structures. end connection. After the fixing bracket is assembled...

AI Technical Summary

Problems solved by technology

but if figure 1 There is a problem with the existing fixing bracket 2 shown: the connecting line of the thermal fuse and the fixing bracket 2 are fixed with a silicone glass fiber tube with a larger diameter, and the connection line of the thermistor and the ground wire The diameter is smaller, and the connecting wires of the hot-melt insurance fixed at the hollow part 21 places on both sides of the fixed bracket 2 are fixed at the same time two, which causes when binding the wires with a bundle, due to the double thermal-melt connecting wires If the stress is too concentrated, it is difficult for the binding point to approach more upwards, which reduces the effect of reducing the diameter of the binding line, so that the temperature sensor may still be stuck when in use.
