A wire passing sealing device and a refrigerator

Abstract

The invention discloses a wire passing sealing device and a refrigerator, and relates to the field of household appliances. The invention is invented to solve the problems of unstable sealing and unreliable fixing of connecting wires in the wire passing holes in the prior art. The wire passing sealing device of the present invention includes: a positioning plate, on which a first wire passing hole is opened; a wire passing sleeve, which is fixedly connected to the positioning plate, and the wire passing sleeve The cylinder is provided with a second wire passing hole in the axial direction; a sealing sleeve, the sealing sleeve is made of elastic material, and a third wire passing hole is arranged in the sealing sleeve, and the side wall of the third wire passing hole is matched with a In the second wire passing hole, the outer surface of the side wall of the third wire passing hole cooperates with the inner wall of the second wire passing hole through a tapered surface structure. The wire passing sealing device and the refrigerator of the present invention can be used to seal the wire passing holes.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a wire passing sealing device and a refrigerator. Background technique [0002] With the development of technology, refrigerators are gradually developing in the direction of electronics, such as displaying the temperature inside the refrigerator to facilitate temperature control. Usually, the temperature sensor and the main control board of the refrigerator are set The display device connected to the main control board is set on the outer wall of the refrigerator door to display the temperature inside the refrigerator, which is convenient for users to check. If the display device on the outer wall of the door is not sealed, the foaming material inside the refrigerator door will leak out if the connecting wires enter the refrigerator door, which will affect the cleanliness of the refrigerator. At the same time, the foaming material in the refrigerator door will The reduction ...

AI Technical Summary

Problems solved by technology

[0004] The sealing method of the above-mentioned wire hole can realize the sealing of the wire hole and the fixing of the connecting wire, but there are still the following disadvantages: 1. The winding operation of the sponge strip on the connecting wire takes a long time, resulting in low sealing efficiency; The friction between the completed sponge strip and the connecting wire is large, and it is difficult to adjust the winding position of the sponge strip on the connecting wire; 3. The amount of winding of the sponge strip and the degree of tightness cannot be determined, resulting in low sealing reliability; 4. The sponge strip The depth of insertion in the wire hole cannot be fixed, resulting in the uncertainty of the outlet length of the connecting wires at both ends of the wire hole, which affects the subsequent connection operation; 5. The fixing of the connecting wire only depends on the friction between the connecting wire and the sponge strip force and the friction between the sponge strip and the wire hole, the stability and reliability are low, and it is easy to loosen. At this time, the connecting wire shakes in the wire hole to generate friction, which accelerates the wear of the connecting wire
