The edge of the partition member 21 contacts the inner side surface 13 </ b> B of the housing 2 in a state where the electronic circuit unit 4 is arranged in the internal space 11 of the housing 2. Specifically, the edge portion of the partition member 21 contacts the midway portion of the inner surface 13B in the opening direction (X-axis direction) of the housing 2. Thereby, the partition member 21 is positioned between the bottom surface 13A of the housing 2 and the opening 12 so that the plate thickness direction is directed to the opening direction.

  The isolation space 11 </ b> A is configured by a bottom surface 13 </ b> A of the housing 2, a region of the inner side surface 13 </ b> B of the housing 2 that is close to the bottom surface 13 </ b> A, and a partition member 21. That is, the isolation space 11 </ b> A in the present embodiment is a space on the bottom surface 13 </ b> A side with respect to the partition member 21 in the opening direction in the internal space 11. On the other hand, a space on the opening 12 side of the partition member 21 in the internal space 11 is an exposed space 11B exposed to the outside through the opening 12. The insertion part 14 of the housing | casing 2 mentioned above is provided so that it may be located in the exposure space 11B.

  The edge part of the partition member 21 is comprised by the sealing material 23 which has elasticity. The sealing member 23 is elastically compressed and deformed when the edge portion of the partition member 21 contacts the inner surface 13 (inner surface 13B) of the housing 2, so that the partition member 21 and the inner surface 13 ( It plays the role of packing that closes the gap with the inner surface 13B). The sealing material 23 may be, for example, rubber or sponge.

  The partition member 21 is supported by the support member 17 of the housing 2 in a state where the electronic circuit unit 4 is accommodated in the internal space 11. That is, the housing 2 further includes a support member 17. The support member 17 extends from the inner surface 13 of the housing 2 toward the opening 12. The support member 17 may extend from the inner side surface 13B of the housing 2 toward the opening 12, for example. In the present embodiment, the support member 17 extends from the bottom surface 13 </ b> A of the housing 2 toward the opening 12. The first surface 21 </ b> A of the partition member 21 facing the isolation space 11 </ b> A is in contact with the distal end of the support member 17 in the extending direction. Thereby, the partition member 21 is supported by the support member 17.

  The support member 17 is arranged so that the tip thereof abuts on the peripheral area of the first surface 21 </ b> A of the partition member 21. Although the support member 17 may be formed in arbitrary shapes, such as plate shape, for example, in this embodiment, it is formed in rod shape. Further, the plurality of support members 17 are arranged at intervals. Specifically, one support member 17 is disposed in the vicinity of each corner of the side wall 16B of the housing 2 in a front view when the housing 2 is viewed from the opening 12 side as shown in FIG. Thereby, the partition member 21 is stably supported by the support member 17. The support member 17 may be in contact with, for example, the inner side surface 13B of the housing 2, but in the present embodiment, the support member 17 is arranged with a space from the inner side surface 13B.

  The partition member 21 is attached to the inside of the housing 2 by being screwed to the support member 17 described above. Specifically, a female screw hole 18 is formed at the tip of the support member 17. Thereby, the partition member 21 is screwed into the female screw hole 18 of the support member 17 after passing the screw 19 from the second surface 21B side of the partition member 21 facing the first surface 21A to the opposite side to the partition member 21. As a result, the support member 17 is fixed to the tip. The 2nd surface 21B of the partition member 21 in this embodiment is a surface which faces the exposed space 11B side (opening 12 side of the housing | casing 2).

As shown in FIGS. 1, 3, and 4, the electronic circuit unit 22 is provided on the first surface 21 </ b> A of the partition member 21.
The specific configuration of the electronic circuit unit 22 may be arbitrary. The electronic circuit unit 22 of the present embodiment includes a power supply unit 24, an antenna unit 25, and a control circuit unit 26. The power supply unit 24 supplies power to the antenna unit 25 and the control circuit unit 26. The antenna unit 25 transmits and receives various types of information between the electronic device apparatus 1 and an external device. Various types of information include, for example, the amount of power generated by a solar panel. The control circuit unit 26 controls the operation of the power supply unit 24 and performs communication control with an external device using the antenna unit 25 and the like.

  The power supply unit 24 constitutes a first circuit unit 22A that generates heat when energized. The antenna unit 25 and the control circuit unit 26 constitute a second circuit unit 22B that is weak against heat as compared with the power supply unit 24 that is the first circuit unit 22A. The first circuit portion 22A and the second circuit portion 22B are arranged in the first direction (Y-axis direction) along the first surface 21A of the partition member 21. The first direction in the present embodiment is the horizontal direction.

  As shown in FIGS. 4 and 5, the electronic circuit unit 22 further includes a cover unit 27 that covers the power supply unit 24 that is the first circuit unit 22 </ b> A. Vents 28 penetrating into and out of the cover portion 27 are formed at both ends of the cover portion 27 in the second direction (Z-axis direction) orthogonal to the first direction along the first surface 21A of the partition member 21.

The first side wall portion 27A is located between the first circuit portion 22A and the second circuit portion 22B (antenna portion 25, control circuit portion 26). The third side wall portion 27C is located above the first circuit portion 22A, and the fourth side wall portion 27D is located below the first circuit portion 22A.
The vent hole 28 is formed in the third side wall portion 27C and the fourth side wall portion 27D. Further, the vent hole 28 is formed at an end portion of the second side wall portion 27B on the third side wall portion 27C side. The vent 28 is not formed in the first side wall portion 27A.

  By providing the cover part 27 as described above, air flows in the second direction so as to pass through the inside of the cover part 27. In the present embodiment, since the second direction is the vertical direction, low temperature air is introduced into the cover portion 27 from the vent hole 28 of the fourth side wall portion 27D by convection, and high temperature air is introduced into the second side wall portion. The air is discharged to the outside of the cover portion 27 through the vent holes 28 of the 27B and the third side wall portion 27C.

  Although the control circuit part 26 which comprises the 2nd circuit part 22B is smaller than the emitted-heat amount of the power supply part 24, it heat | fever-generates by electricity supply. On the other hand, the antenna unit 25 does not generate heat or the amount of generated heat is smaller than that of the control circuit unit 26. For this reason, the control circuit unit 26 is located above the antenna unit 25 in the second direction. Thereby, it can suppress that the antenna part 25 receives the influence of the heat of the control circuit part 26. FIG.

As shown in FIGS. 1 to 3, the electronic circuit unit 4 of the present embodiment further includes a connection terminal 29 connected to the electronic circuit unit 22. The connection terminal 29 is provided so as to be exposed on the second surface 21B side of the partition member 21.
Various wirings for connecting the electronic circuit unit 22 and external devices (for example, the wiring 15 inserted through the insertion unit 14) are detachably connected to the connection terminal 29. The external device may include an external device for operating the control circuit unit 26, for example. The connection terminal 29 is preferably configured so that various wirings can be easily inserted and removed.

  The electronic circuit unit 4 further includes a grip portion 30 provided on the second surface 21 </ b> B of the partition member 21. The gripping part 30 is a part that the operator grips with his / her hand when the electronic circuit unit 4 is taken in and out of the housing 2. In the illustrated example, the grip portion 30 may protrude from the second surface 21B as in the illustrated example, but is not limited thereto.

The grip portion 30 and a part of the support members 17A (hereinafter referred to as the rotation support member 17A) among the plurality of support members 17 of the housing 2 described above are arranged to satisfy the following requirements. ing.
As shown in FIG. 1, the rotation support member 17 </ b> A is directed to the grip portion 30 from the first surface 21 </ b> A to the second surface 21 </ b> B with its tip in contact with the first surface 21 </ b> A of the partition member 21. By applying a force in the direction, the partition member 21 is arranged around the rotation axis including the contact point P1 between the tip of the rotation support member 17A and the first surface 21A. Further, the grip portion 30 is disposed at a position where the distance L1 between the grip portion 30 and the rotation axis is longer than the distance L2 between the center of gravity C1 of the electronic circuit unit 4 and the rotation shaft.
Hereinafter, this point will be specifically described.

  The rotation support member 17A is disposed at a position where the tip thereof abuts on the first end portion (lower end portion in FIG. 1) of the partition member 21 in the second direction (Z-axis direction). On the other hand, the grip portion 30 is disposed at the second end portion (upper end portion in FIG. 1) of the partition member 21 in the second direction. Thus, when a force is applied to the grip portion 30 in the direction from the first surface 21A to the second surface 21B, as shown in FIG. 6, the tip of the rotation support member 17A and the first surface 21A The partition member 21 can be rotated around the rotation axis centered on the contact point P <b> 1. Reference sign R <b> 1 in FIG. 6 indicates the rotation direction of the partition member 21.

  In the electronic circuit unit 4, the electronic circuit unit 22 is heavier than the partition member 21 and the connection terminal 29. For this reason, the position of the center of gravity C <b> 1 of the electronic circuit unit 4 depends on the position of the electronic circuit unit 22 in the partition member 21. In the present embodiment, as shown in FIG. 1, the electronic circuit portion 22 is located between the rotation support member 17 </ b> A and the grip portion 30 in the second direction. Accordingly, the center of gravity C1 of the electronic circuit unit 4 is located between the rotation support member 17A and the grip portion 30 in the second direction. That is, the distance L1 between the grip portion 30 and the rotation axis is longer than the distance L2 between the center of gravity C1 of the electronic circuit unit 4 and the rotation axis.

  Installation work and maintenance work of the electronic device apparatus 1 configured as described above may be performed in a state where the opening 12 of the housing 2 is opened. This is because the installation work and maintenance work of the electronic device apparatus 1 include work of connecting various wirings (for example, the wiring 15) to the electronic circuit unit 22. In the electronic device device 1 of this embodiment, the electronic circuit unit 22 is isolated from the outside by the partition member 21 even when the opening 12 of the housing 2 is opened. Thereby, the installation work and maintenance work of the electronic device apparatus 1 can be performed without exposing the electronic circuit unit 22 to the outside.

  Further, when taking out the electronic circuit unit 4 from the housing 2 in the maintenance work of the electronic apparatus device 1 of the present embodiment, the operator may hold the grip portion 30 and pull it to the outside of the housing 2. Here, the grip portion 30 is located farther than the center of gravity C1 of the electronic circuit unit 4 with respect to the contact point P1 between the partition member 21 and the rotation support member 17A. For this reason, even if the electronic circuit unit 4 is heavy, the operator can easily take out the electronic circuit unit 4 from the housing 2 by the lever principle only by applying a smaller force to the grip portion 30.

As described above, according to the electronic apparatus device 1 of the present embodiment, the electronic circuit unit 22 is moved outside by the partition member 21 even when the opening 12 of the housing 2 is opened in order to perform installation work and maintenance work. Can be isolated.
Moreover, according to the electronic device apparatus 1 of the present embodiment, the electronic circuit unit 22 is provided on the first surface 21A of the partition member 21 facing the isolation space 11A. For this reason, the electronic circuit unit 4 including the partition member 21 and the electronic circuit unit 22 is simply inserted into and removed from the housing 2, or the electronic circuit unit 4 is replaced with another electronic circuit unit 4. The maintenance work 22 can be performed in a short time. That is, it is possible to prevent the electronic circuit unit 22 from being exposed to the external environment for a long time during maintenance of the electronic circuit unit 22.
From the above, the electronic circuit unit 22 can be suitably protected from the external environment, and deterioration of the electronic circuit unit 22 due to the external environment can be suitably suppressed.

  Moreover, according to the electronic device apparatus 1 of the present embodiment, the connection terminal 29 connected to the electronic circuit unit 22 is provided so as to be exposed on the second surface 21B side of the partition member 21. For this reason, even when the opening 12 of the housing 2 is opened, only the connection terminal 29 is exposed to the outside, and the electronic circuit unit 22 is isolated from the outside. Therefore, the electronic circuit unit 22 can be protected from corrosive substances when the electronic circuit unit 22 is connected to an external device.

  Further, according to the electronic apparatus device 1 of the present embodiment, when the electronic circuit unit 4 is taken out from the housing 2, the operator simply pulls the grip portion 30 to the outside of the housing 2 with a small force. The electronic circuit unit 4 can be easily removed from the housing 2 according to the principle. Thereby, the maintenance work of the electronic circuit unit 22 in the external environment can be further shortened.

  Further, according to the electronic device device 1 of the present embodiment, the partition member 21 is attached to the inside of the housing 2 by being screwed to the support member 17 that supports the partition member 21. That is, the support member 17 has a function of fixing the partition member 21 to the housing 2. For this reason, it is not necessary to separately provide a structure for fixing the partition member 21 to the housing 2. Thereby, reduction of the number of components of the electronic device apparatus 1 can be aimed at.

  Moreover, according to the electronic device apparatus 1 of the present embodiment, the edge of the partition member 21 that contacts the inner surface 13 of the housing 2 is configured by the sealing material 23 having elasticity. For this reason, the space (isolation space 11 </ b> A) in which the electronic circuit unit 22 is arranged in the housing 2 can be reliably isolated from the outside by the partition member 21.

  Moreover, according to the electronic device apparatus 1 of this embodiment, the housing | casing 2 is formed with the resin material. For this reason, it can prevent that the housing | casing 2 obstructs radio | wireless communication with the antenna part 25 and an external apparatus.

Further, according to the electronic device device 1 of the present embodiment, the first circuit portion 22A that generates heat in the electronic circuit portion 22 is covered by the cover portion 27, and in the second direction along the first surface 21A of the partition member 21. Vents 28 are formed at both ends of the cover portion 27. Thereby, air can be flowed in a 2nd direction so that air may pass the inside of the cover part 27, and heat dissipation of 22 A of 1st circuit parts can be promoted.
In particular, in the present embodiment, since the second direction is the vertical direction, low temperature air is introduced into the cover portion 27 from the vent 28 formed in the lower end portion of the cover portion 27 by convection, and high temperature air is introduced. The air can be discharged to the outside of the cover portion 27 from the vent 28 formed in the upper end portion of the cover portion 27. Therefore, the heat dissipation efficiency of the first circuit portion 22A can be improved.

  In addition, the second circuit portion 22B that is vulnerable to heat in the electronic circuit portion 22 is arranged in a first direction orthogonal to the second direction with respect to the first circuit portion 22A. For this reason, it can suppress that the air of the high temperature which flowed out from the vent hole 28 of the cover part 27 reaches | attains the 2nd circuit part 22B. That is, it is possible to suppress the second circuit portion 22B from being affected by the heat of the first circuit portion 22A.

  Moreover, according to the electronic device apparatus 1 of the present embodiment, the inner side surface 13B of the housing 2 with which the edge of the partition member 21 abuts is spaced from the inner surface 13B facing each other from the bottom surface 13A side of the housing 2. It inclines with respect to the bottom face 13A so that it may become large as it goes to the opening 12 side. For this reason, when the electronic circuit unit 4 is accommodated in the internal space 11 of the housing 2, the entire edge of the partition member 21 can be reliably brought into contact with the inner side surface 13 </ b> B of the housing 2. That is, the space (isolation space 11 </ b> A) in which the electronic circuit unit 22 is arranged in the housing 2 can be reliably isolated from the outside by the partition member 21.

  Although the details of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

  In the electronic device device of the present invention, the partition member of the electronic circuit unit may be arranged inside the housing so that the entire internal space of the housing is an isolation space, for example.

  In the electronic device apparatus of the present invention, the first circuit unit of the electronic circuit unit is not limited to the power supply unit, and may be any circuit unit that generates heat when energized. The second circuit unit is not limited to the control circuit unit and the antenna unit, and may be any circuit unit that does not generate heat or has a smaller amount of heat generation than the first circuit unit.
