Description

Technical Field

[0001] The utility model belongs to the technical field of electronic component switches, and particularly relates to a moisture-proof structure of an electronic component switch. Background Art

[0002] Electronic components can be individual packages, such as resistors, capacitors, inductors, transistors, diodes, etc., or groups of varying complexity, such as integrated circuits. They play an important role in connecting, controlling and converting electronic signals, and are the basic building blocks for building electronic devices and systems. Electronic component switches are electronic components used to control the on and off states of circuits, and are one of the basic components in electronic circuits.

[0003] After searching, it is found that the authorization announcement number is CN 215417929 U, which is a moisture-proof structure of an electronic component switch. The structure includes a switch body, a shell is fixedly provided on the top of the switch body, and moisture-proof components are fixedly provided on both sides of the switch body. The two moisture-proof components include a moisture absorption cavity, a moisture absorption cotton layer and a moisture-proof cavity. The two moisture absorption cavities are respectively fixedly arranged on both sides of the switch body. The interiors of the two moisture absorption cavities are filled with moisture absorption cotton layers. One side of the two moisture absorption cotton layers is fixedly provided with a moisture-proof cavity. The electronic component switch can absorb moisture and moisture mixed in the external air through the two moisture absorption cotton layers. At the same time, the desiccant can remove the steam generated by the long-term operation of the electronic component, so that the moisture-proof effect of the switch is better; the connecting rod is driven to rise and fall by stretching the piston rod of the cylinder. When the connecting rod rises and falls, it drives the two pressing plates to squeeze the two moisture absorption cotton layers respectively, so that the moisture absorbed by the two moisture absorption cotton layers flows to the outside of the electronic component switch through the two water seepage holes.

[0004] In the above process, the cylinder needs to be manually started from time to time to squeeze the moisture-absorbing cotton layer. In addition, the ventilation holes cannot be automatically opened and closed according to needs, which makes it easy for external humid air to enter the switch body through the ventilation holes, reducing the practicality and moisture-proof effect of the equipment.
