[0001] The utility model relates to a wire temperature sensor, in particular to a wire temperature sensor switch contactor with a protection function. Background Art
[0002] Conductor refers to the material used for wires and cables, and also refers to wires in industry. It is generally made of copper or aluminum, and can also be made of silver wire (good electrical and thermal properties), used to conduct current or heat. Wires are very important materials in the automation industry and even the electrical industry. Wire connection is a basic skill that electricians need to master. When the circuit is transmitted through the wire, in order to ensure the normal transmission of the current, a contact temperature sensor can be installed on the outside of the transmission wire to monitor the temperature of the wire accordingly.
[0003] At present, the operation of the wire temperature sensor is controlled by a switch contactor. During use, the switch contactor is exposed to the outside world for a long time, which easily accumulates dust, causing poor contact at the least and local heating at the worst, with the risk of causing a short circuit or even a fire. However, the switch contactor is often fixed on the wall, causing the switch contactor to protrude from the wall, further increasing the risk of collision of the switch contactor.
