Furthermore, the probe shell be the injection molding, integrative injection moulding between thermistor and the probe shell, for the connected mode of thermistor grafting income protective housing among the prior art, owing to adopt integrative injection moulding's mode, there is not air between thermistor and the probe shell basically to the problem of heat conduction when having avoided the air can influence the detection temperature has improved the accuracy of temperature measurement.

Further, the temperature measuring device further comprises an injection molding connecting piece, wherein the injection molding connecting piece is fixedly arranged between the temperature measuring probe and the wire body, and the injection molding connecting piece, the temperature measuring probe and the wire body are integrally formed in an injection molding mode, so that sealing between the pin and the probe shell and between the pin and the wire body is realized.

Furthermore, the temperature measuring probe also comprises a protective sleeve which is sleeved outside the probe shell, so that the temperature measuring probe is prevented from being damaged due to installation actions such as crimping and the like.

Furthermore, the injection molding connecting piece is formed by injection molding of synthetic rubber, preferably a TPE (thermoplastic elastomer) material, and is well welded with the wire body and good in waterproof performance.

Furthermore, the protective sheath also adopts the TPE material to mould plastics and forms, has avoided the risk that the head probably caused when crimping leaks, and protective sheath, probe shell, the connecting piece of moulding plastics are the injection molding simultaneously, guarantee no air between the three, improve sensor data survey's accuracy.

Compared with the prior art, the utility model discloses the beneficial effect who has is:

1. the connection between the temperature measuring probe and the wire body is realized by adopting a 90-degree pin, so that the overall length size of the miniature waterproof temperature sensor is reduced, and the miniature waterproof temperature sensor is adaptive to a narrow installation space of a medical miniature refrigerator;

2. adopt a plurality of injection molding, not only improved waterproof lamp sealing performance, still improved the toughness of this patent sensor, avoided leading to the condition of damage because of physics nature external force.
