法も検討されている。2. Description of the Related Art With the high density and high integration of electric and electronic components, the presence and dew condensation of high humidity water vapor on component housings and packages is accompanied by deterioration of electrical contacts or dust contamination on clean surfaces. It is becoming very hated. In addition, there is an increasing need to avoid extreme attachment of moisture to the end face of the optical connector, the crystal end face of the optical component, or the cleavage crystal end face of the optical semiconductor element. To this end, sealing with a hermetic seal, metal can sealing with dry nitrogen, argon, or helium pressure sealing has been devised with various shapes and ideas. Also,
In order to prevent moisture intrusion, a resin molding method of embedding such an electronic component or an optical component with a resin with almost no void has been studied.

が掛かるものであった。[0003] However, it is difficult to completely prevent moisture and water vapor in a normal environment. Even when a closed casing is used, sealing in a dry room, gas replacement in a vacuum environment, and the like are necessary, and controlling the humidity is extremely laborious and costly.

った。[0004] Further, since a housing or a package for housing such components is used in various environments, at the time of manufacture,
Even in a low humidity or completely dry state, it was impossible to completely control the moisture due to the subsequent penetration of moisture under the use environment or deformation of the package sealing portion due to temperature change.

3. The moisture-discharging cylindrical portion 44 and the water-impermeable / moisture-permeable cloth material 45 indicate the respective component names.

は外部に対して低い相対湿度に保たれる。[0007] The moisture-proof mechanism of this configuration is as follows. When water enters the inside of the headlamp, dew condensation or the like occurs inside the headlamp, and the irradiation light of the lamp 42 is scattered, which adversely affects the lamp function. However, since the lamp 42 needs to be replaced and cannot be completely sealed, the lamp housing is covered with a non-permeable and moisture-permeable cloth material 45 which is made of a moisture-permeable and non-permeable fluororesin. A cylindrical portion 44 is provided.
When the lamp 42 is turned on and the lamp housing composed of the light front glass part 43 and the housing 41 is heated,
Water droplets inside the lamp evaporate, and the moisture-permeable and water-impermeable cloth 45
Through the outside. Since the water-impermeable and moisture-permeable cloth material 45 does not allow water droplets to pass through, even if the lamp housing gets wet with raindrops or the like, water droplets do not enter inside. As a result, if the lamp maintains a high temperature relative to the external temperature even when the lamp is turned on or off, the humidity inside the lamp housing is maintained at a relative humidity lower than the outside.

不可能であった。FIG. 5 shows an example in which the conventional humidity control is performed on the external environmental humidity by utilizing the physical deformation of the humidity control member. The content is the schoolhouse building used for the building wall of Nara Shosoin. In the figure, reference numerals 51 and 53 denote humidity-modifying material components such as wood whose shape changes depending on the external environmental humidity, 52 denotes a ventilation state interrupted by a deforming component material expanding under high humidity, and 54 denotes a dry state and free. The respective ventilation states are shown below. In the figure, the left figure shows that the humidity deformable material constituents 51 expand in a high humidity state and block the ventilation by contacting each other, and the right figure shows the deformable material structure in a dry state. It is shown that the material 53 contracts and a gap is formed between the deformable material constituent materials 53 so that the ventilation is possible. In the above conventional examples, each is designed to perform the humidity control skillfully by making use of the characteristics of the constituent members, but in the example of FIG. 4, when the temperature inside the lamp housing is equal to or lower than the outside, The humidity control function of the water-impermeable and moisture-permeable cloth does not work. Similarly, the humidity valve mechanism of FIG. 5 cannot maintain the internal humidity below the external environmental humidity.

The main feature is to open and close the housing. Hereinafter, the configuration of the present invention will be briefly described with reference to the drawings.

And an external power supply 7. Here, the moisture-proof valve member is constituted by the external water-impermeable / moisture-permeable cloth material 2, the internal water-impermeable / moisture-permeable cloth material 3, and the water-absorbing cotton-like member 4. Basically, the moisture-proof valve part 1 is provided with a communication hole with the outside in a part of the housing to be conditioned.

態に保たれる。FIG. 2 shows a model diagram of the operation principle. Normally, as shown in FIG. 1, the water-absorbent cotton-like member 4 and the internal water-impermeable and moisture-permeable cloth material 3 have a gap G. If the external environment is normal and the heat source 6 inside the housing 5 is in a heated state, the moisture in the housing 5 evaporates, passes through the internal water-impermeable / moisture-permeable cloth material 3 and firstly becomes The member 4 absorbs moisture. At the same time, only the vapor passes through the outer impermeable / moisture-permeable cloth material 2 and radiates to the outside from the gap and the surface with the water-absorbing cotton-like member 4 by the internal vapor pressure (positive pressure). In this state, the relative humidity inside the housing 5 is in equilibrium with the vapor pressure of the water absorbed by the water-absorbent cotton member 4 at the same temperature. Generally, the water vapor pressure adsorbed by the water-absorbent cotton-like member 4 is lower than the vapor pressure in the free state.
The inside of the housing 5 reaches a value lower than the external relative humidity and is kept in that state.

This indicates a state in which the internal power supply has stopped and the temperature has dropped.
In this state, water such as water droplets does not invade directly from the outside by the external non-permeable and moisture-permeable cloth material 2, but water vapor passes through and reaches the moisture-proof valve front chamber. However, here, the moisture is absorbed by the water-absorbent cotton-like member 4, and the water vapor is adsorbed by the water-absorbent cotton-like member 4 to form a gel, and the water-absorbent cotton-like member 4 swells. As a result, the gap between the inner water-impermeable and moisture-permeable cloth material 3 is filled, and the swollen water-absorbent cotton-like member 4 comes into contact with the inner water-impermeable and moisture-permeable cloth material 3 in a gel state, and the moisture-proof valve 1
Is closed. Since the gel portion in contact with the inner water-impermeable / moisture-permeable cloth material 3 shows a liquid state, moisture cannot enter the housing 5 due to the water impermeability of the internal water-impermeable / moisture-permeable cloth material 3.

３とギャップを持つ状態に戻る。As shown in the lower part of the center of FIG. 2, when the external environment changes to the normal state, the water gradually evaporates from the outside of the water-absorbent cotton-like member 4 and the water-absorbent cotton-like member 4 shrinks. Then, as in the initial stage, the state returns to a state having a gap with the internal water-impermeable and moisture-permeable cloth material 3 inside the housing 5.

作を継続できる。Because of such an operation mechanism, the inside of the housing provided with the moisture proof valve according to the present invention is always kept at a low humidity, and its humidity control function is self-repairing in accordance with the operation of the internal power supply and changes in the external environment. , And the operation can be continued extremely efficiently and rationally.

繊維による積層布８が設けられていることである。FIG. 3 is a principle operation diagram of the invention according to claim 3 of the present invention. The difference from FIG. 1 and FIG. 2 is that a semi-absorbent fiber having a smaller fiber diameter from the inside to the outside is provided between the external moisture-permeable / non-permeable cloth material 2 and the water-absorbent cotton-like member 4. That is, the laminated cloth 8 is provided.

It can be sucked out. Since the outermost layer is the water-impermeable and moisture-permeable cloth material 2, the water evaporates here and this cycle is repeated.
