Specific embodiment
The enforcement it is clear that described will be clearly and completely described to the technical scheme in the embodiment of the present invention below
Example is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
The every other embodiment that technical staff is obtained under the premise of not making creative work, broadly falls into the model of present invention protection
Enclose.
The core of the present invention is by arranging low temperature resistant electric connector inside low temperature refrigerator, changing straight during temp probe
It is connected on refrigerator inside plug electric connector, avoid the problem of temp probe cable icing frosting at heat insulation path.
Refer to Fig. 2-Fig. 5.
A kind of low temperature refrigerator temp probe antifrost method, installs antifrost connector 6 inside low temperature refrigerator 1, patches
Part one end connects temp probe 2, and the other end passes through heat insulation path 4 and connects temperature acquisition terminal 5 through cable 5.
A kind of low temperature refrigerator temp probe antifrost structure, including the temp probe 2 being arranged within low temperature refrigerator 1, prevents
Frosting plug connector 6, and temperature acquisition terminal 5 and electric connector 7, the sensor cable 603 of temp probe 2 passes through antifrost
