Description

Technical Field

[0001] The utility model relates to the technical field of mutual inductor moulds, in particular to a contact type temperature sensing wire fixing device used in mutual inductor moulds. Background Art

[0002] Before pouring the transformer product, the product mold needs to be preheated and kept at a constant temperature for a period of time as required by the process. When the product is poured, the resin and coil can be heated evenly and effectively connected with the subsequent curing process. Therefore, preheating and constant temperature maintenance of the mold are very important in the production and manufacturing of transformer products. One end of the contact temperature sensing line is in contact with the object to be measured, and the other end is connected to the temperature display device (generally a thermometer). When the contact temperature sensing line has good contact with the object to be measured, thermal equilibrium is achieved through conduction or convection, so that the contact temperature sensing line and the object to be measured are at the same temperature, so that the indication of the thermometer can directly represent the temperature of the object to be measured. Generally speaking, its measurement accuracy is relatively high. However, in actual use, due to factors such as the movement, handling, and replacement of the mold, the contact temperature sensing line is easy to fall off the mold, causing temperature display distortion, mold overheating, etc., which in turn affects the electrical and mechanical properties of the transformer product after casting, resulting in unqualified products. Summary of the invention
