As a result, dew condensation may occur on the electrical equipment or electrical / electronic equipment in the box, and insulation failure or leakage may occur. Such a problem is particularly likely to occur in a box installed outdoors. According to observation records from the Japan Meteorological Agency, the temperature dropped by about 20 ° C in one hour and by about 22 ° C in day and night. In a box installed outdoors, the temperature inside the box suddenly changes due to a change in the external environment, and the relative humidity sometimes changes abruptly. Conventionally, in order to solve such a problem, a humidity control material is installed in the box.

  The humidity conditioning material is configured using a material that can adsorb water vapor even at a relative humidity of 100% or less, for example. The humidity conditioner adsorbs water vapor or releases the adsorbed water according to changes in the external environment. Thereby, the change in the relative humidity of the surroundings can be reduced.

  As an example of the humidity control material as described above, the following Patent Document 1 describes a method of suspending a sheet-type humidity control material from a box door as a method for mounting a humidity control material made of a water-absorbing polymer in a box. Has been.

As shown in FIG. 15, in the outdoor installation distribution box 100, three humidity control members 102 are suspended from the inner surface of the door 101. Specifically, as shown in FIG. 16, suspension holes 103 are formed in the upper edge portion and the side edge portion of the plate-like humidity control member 102, and the humidity control member 102 is provided with this suspension. It is suspended from the inner surface of the door 101 by a string-like member inserted through the lowering hole 103.

As described above, by disposing the humidity adjusting member 102 in the outdoor installation distribution box 100, the humidity in the outdoor installation distribution box 100 can be maintained even when the electric / electronic device storage box is not energized. It can suppress becoming high.

In the present embodiment, the electric / electronic device 13 is fixed to the inner wall 12 of the electric / electronic device storage box 1. The type of the electric / electronic device 13 is not particularly limited. The electrical / electronic device 13 may be, for example, various electronic components such as a distribution board, an operation panel, and a communication device.

  As shown in FIG. 1, a plurality of humidity control members 20 are attached to the inner wall 12 of the electrical / electronic device storage box 1. The humidity control member 20 is a member that absorbs and releases moisture according to the relative humidity in the environment where the humidity control member 20 is disposed.

  The humidity control member 20 is formed of, for example, an inorganic porous body. As an inorganic porous body which comprises the humidity control member 20, the inorganic porous body which contains at least one of an amorphous silica and a silicate compound as a main component is mentioned, for example. Specific examples of the silicate compound include allophane, imogolite, vermiculite, palygorskite, and clay minerals such as diatomaceous earth.

  The difference in the equilibrium water content between the relative humidity of 75% and the relative humidity of 40% in the environment of the temperature adjustment member 20 at a temperature of 5 ° C. to 50 ° C. is preferably 9.5 mg / g to 55.0 mg / g, It is more preferably 10.0 mg / g to 50.0 mg / g, and further preferably 20.0 mg / g to 45.0 mg / g. Here, the equilibrium water content means the maximum amount of water vapor that can be adsorbed in a predetermined relative humidity environment per unit weight of the material.
