Description

Evaporator temperature sensor fixing structure

Technical Field

The utility model relates to a fixing structure of an evaporator temperature sensor.

Background

Most of the currently used evaporator temperature sensors are plug-in sensors, signals of the sensors are transmitted to an air conditioner controller through wires, and the wires are led out of a shell of the air conditioner box from a temperature measuring point of the evaporator in the air conditioner box. When the distribution position of the evaporator temperature sensor is far away from the wire outlet hole, the length of the lead of the sensor in the box body is long.

If the longer wire can't be fixed on the evaporimeter core, the wire strikes the core at the in-process of car motion, may produce the abnormal sound, also can damage the wire line skin, leads to the sensor wire to intake, and the sensor short circuit, the measurement temperature is inaccurate, and the compressor opens and stops the malfunction. In addition, the excessively long conducting wire transversely spans on the surface of the core body, so that the wind resistance is increased, and the refrigeration effect is influenced.

Wire fixation clamps that generally use on the market all are similar with bayonet resistance clamp, and such resistance clamp can destroy the fin after inserting the core, and difficult the pulling out, in case the operation mistake can lead to the evaporator core to scrap.
