[0004] Water adhering to cables such as electrical wires and optical fibers installed inside the housing may travel along the cables and enter the inside of the housing. [Means for solving the problem]

[0005] The present disclosure can be realized in the following forms.

[0006] (1) According to one embodiment of the present disclosure, there is provided a housing to be fixed to a wall surface. The housing includes a back member having a back surface facing the wall surface. The back member includes a storage groove provided on the back surface for storing a cable extending from inside the housing to outside the housing, a rib protruding from a side wall surface of the storage groove and contacting the cable stored in the storage groove, and a drain groove provided on the back surface so as to communicate with the storage groove and through which water adhering to the rib flows.

According to this type of housing, water can be guided to the drain, thereby preventing water from entering the housing through the cable. (3) In the housing of the above aspect, the housing may be fixed to the wall surface via a fixing member, and the rib may be in contact with the fixing member. According to the housing of this configuration, the water blocked by the ribs can be directed to the fixing member, thereby preventing water from entering the housing along the cable. (4) In the housing of the above aspect, the rib may have an inclined surface that is inclined so that the position of the rib becomes lower as it approaches the fixing member. According to the housing of this configuration, water can be guided to the fixing member, and therefore water can be prevented from entering the housing through the cable. (5) In the housing of the above form, the fixing member has an opening through which the cable passes, and the lower edge of the opening has a portion that overlaps the rib and a portion that overlaps the drain groove when viewed perpendicular to the back surface, and may be inclined so that the position becomes lower the closer it is to the drain groove from the rib. According to this type of housing, the water blocked by the ribs can be guided to the drain groove via the lower edge of the opening of the fixing member. The present disclosure can be realized in various forms other than a housing, for example, in the form of an electronic device. [Brief explanation of the drawings]

[0008] A. First embodiment: Fig. 1 is a perspective view of an electronic device 5 including a housing 10 in a first embodiment. Fig. 2 is a rear view of the electronic device 5. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 2. As shown in Fig. 1, the electronic device 5 includes a housing 10, a circuit board 20, a cable 30, and a fixing member 40. The electronic device 5 is, for example, a security device such as an intercom or a card reader for an IC card-type electric lock, and is used with the housing 10 fixed to an outdoor wall surface WL.

[0009] The housing 10 is configured in a rectangular parallelepiped shape. The housing 10 has a front surface 11, a back surface 12, a top surface 13, a bottom surface 14, a left side surface 15, and a right side surface 16. The housing 10 is fixed to the wall surface WL so that the back surface 12 faces the wall surface WL and the bottom surface 14 faces the direction of gravity G. In this embodiment, the housing 10 is fixed to the wall surface WL via a fixing member 40. In this disclosure, fixing the housing 10 to the wall surface WL includes not only fixing the housing 10 directly to the wall surface WL but also fixing the housing 10 to the wall surface WL via the fixing member 40.

[0010] 1 shows arrows indicating mutually orthogonal X, Y, and Z axes. The X and Y axes are parallel to the horizontal plane, and the Z axis is parallel to the direction of gravity G. The arrows indicating the X, Y, and Z axes are also shown in other figures as appropriate so that the directions indicated by the arrows correspond to those in FIG.

[0011] As shown in FIG. 3 , in this embodiment, the housing 10 includes a rear member 100 and a front member 200. The rear member 100 has a rear surface 12. The front member 200 has a front surface 11, a top surface 13, a bottom surface 14, a left side surface 15, and a right side surface 16. The rear member 100 and the front member 200 are fixed to each other, for example, by screws. By fixing the rear member 100 and the front member 200 to each other, an internal space SP is formed surrounded by the rear member 100 and the front member 200. A gap between the rear member 100 and the front member 200 is sealed by a sealing material (not shown). The rear member 100 and the front member 200 are formed of a resin material, for example, engineering plastic.

[0012] The circuit board 20 is disposed in the internal space SP of the housing 10. The circuit board 20 includes electronic components such as integrated circuits, resistors, capacitors, etc. The circuit board 20 is fixed to the housing 10 with screws, for example.

[0013] The cable 30 extends from the internal space SP of the housing 10 to the external space. In this embodiment, the cable 30 is a power cable for supplying power to the circuit board 20. The leading end of the cable 30 is connected to the circuit board 20. The trailing end of the cable 30 is connected to a power supply source (not shown) through a through-hole provided in the wall surface WL. Note that the cable 30 is not limited to a power cable and may be, for example, an optical fiber cable.

[0014] The fixing member 40 is disposed between the rear surface 12 of the housing 10 and the wall surface WL. The fixing member 40 is fixed to the wall surface WL, for example, with screws. The housing 10 is fixed to the fixing member 40, for example, with screws. As shown in FIG. 2 , in this embodiment, the fixing member 40 is configured as a rectangular plate. An opening 45 is provided in the center of the fixing member 40 for passing the cable 30 through a through-hole in the wall surface WL. The opening 45 is configured in the shape of a parallelogram. An upper edge 46 and a lower edge 47 of the opening 45 are inclined relative to the horizontal plane so that their positions become lower from a left edge 48 to a right edge 49 of the opening 45. The left edge 48 and the right edge 49 of the opening 45 are arranged parallel to the direction of gravity G. The fixing member 40 is formed of a metal material, for example, stainless steel or aluminum alloy.

[0015] Fig. 4 is a rear view of the housing 10 in this embodiment. Fig. 5 is a cross-sectional view of the first rib 140 in this embodiment. As shown in Fig. 4, the rear member 100 of the housing 10 has an inlet 110, a storage groove 120, a first drain groove 130, a first rib 140, a second drain groove 150, and a second rib 160. In this disclosure, the first drain groove 130 may be simply referred to as a drain groove, and the first rib 140 may be simply referred to as a rib.

[0016] The inlet 110 connects the internal space SP of the housing 10 to the external space. The tip of the cable 30 is introduced into the internal space SP of the housing 10 through the inlet 110. In this embodiment, a recess is provided in the lower left portion of the back surface 12, and the inlet 110 is provided on a downward-facing surface constituting the recess. The inlet 110 is provided below the connection between the circuit board 20 and the cable 30. By providing the inlet 110 below the connection between the circuit board 20 and the cable 30, even if water enters the inside of the housing 10 through the inlet 110, it is possible to prevent the water from reaching the circuit board 20. Note that in other embodiments, the inlet 110 may be provided at the same height as the connection between the circuit board 20 and the cable 30 or above the connection between the circuit board 20 and the cable 30.

[0017] The storage groove 120 is provided on the rear surface 12 of the housing 10. The storage groove 120 stores the middle portion of the cable 30. In this embodiment, the storage groove 120 extends obliquely from the lower left to the center of the rear surface 12, from the lower left to the upper right. In other words, the storage groove 120 extends obliquely with respect to the direction of gravity G. The lower end of the storage groove 120 communicates with the inlet 110. The lower end of the storage groove 120 also communicates with the external space below the housing 10.

[0018] The first drain groove 130 is provided on the back surface 12. In this embodiment, the first drain groove 130 is provided to the right of the storage groove 120. The first drain groove 130 extends vertically. In other words, the first drain groove 130 extends parallel to the direction of gravity G. The upper end of the first drain groove 130 communicates with the storage groove 120. The lower end of the first drain groove 130 communicates with the external space below the housing 10. Water that flows into the first drain groove 130 is discharged from the lower end of the first drain groove 130.

[0019] The first rib 140 is provided between the upper and lower ends of the storage groove 120. In this embodiment, the first rib 140 is provided directly below the connection between the storage groove 120 and the first drainage groove 130. The first rib 140 protrudes from one of the two opposing side wall surfaces of the storage groove 120 to the other. In this embodiment, of the left and right side wall surfaces of the storage groove 120, the first rib 140 protrudes from the right side wall surface, which is the side wall surface on the first drainage groove 130 side, to the left side wall surface. The first rib 140 has the function of fixing the cable 30 in the storage groove 120 and the function of guiding water flowing along the cable 30 to the first drainage groove 130.

[0020] Regarding the function of fixing the cable 30 in the storage groove 120, a gap is provided between the tip of the first rib 140 and the left side wall surface of the storage groove 120, and the cable 30 passes through this gap to be stored in the storage groove 120. The cable 30 is pulled downward from the inlet 110, folded back so as not to protrude from the bottom surface 14 of the housing 10, and stored in the storage groove 120. The cable 30 stored in the storage groove 120 is fixed by being sandwiched between the bottom surface of the storage groove 120 and the first rib 140. The width of the gap between the tip of the first rib 140 and the left side wall surface of the storage groove 120 is preferably approximately the same as the thickness of the cable 30. The width of the gap between the first rib 140 and the bottom surface of the storage groove 120 is also preferably approximately the same as the thickness of the cable 30. In this embodiment, the thickness of the cable 30 is several millimeters, and the width of the gap between the tip of the first rib 140 and the left side wall surface of the storage groove 120, and the width of the gap between the first rib 140 and the bottom surface of the storage groove 120 are also several millimeters.

[0021] With regard to the function of guiding water flowing along the cable 30 into the first drain groove 130, the first rib 140 is in contact with the cable 30 stored in the storage groove 120. An upper surface 141 of the first rib 140 is connected to the side wall surface of the first drain groove 130. The upper surface 141 of the first rib 140 is inclined with respect to the horizontal plane so that its position becomes lower as it approaches the base end from the tip end of the first rib 140. Therefore, the first rib 140 can block water flowing downward along the cable 30 and guide it into the first drain groove 130.

[0022] As shown in Fig. 5, in this embodiment, the first rib 140 further has the function of guiding water flowing along the cable 30 to the fixing member 40. In this embodiment, the cross-sectional shape of the first rib 140 is pentagonal, and the first rib 140 has an inclined surface 145 that is inclined so that the position of the first rib 140 becomes lower as it approaches the fixing member 40. The first rib 140 contacts a lower edge portion 47 of an opening 45 provided in the fixing member 40. Therefore, water blocked by an upper surface 141 of the first rib 140 can be guided to the lower edge portion 47 of the opening 45.

[0023] As shown in FIG. 4, the second drain groove 150 is provided on the rear surface 12. The second drain groove 150 has an upstream portion 151 extending laterally from the upper left to the upper right of the rear surface 12, and a downstream portion 152 extending vertically from the upper right to the lower right of the rear surface 12. The upstream portion 151 is provided above the storage groove 120 and the first drain groove 130. The downstream portion 152 is provided to the right of the storage groove 120 and the first drain groove 130. The two opposing side wall surfaces of the upstream portion 151 are inclined with respect to the horizontal plane so that their positions become lower as they approach the downstream portion 152. This allows water that flows into the upstream portion 151 to be guided to the downstream portion 152. The upper end of the downstream portion 152 is connected to the right end of the upstream portion 151, and the lower end of the downstream portion 152 is connected to the external space below the housing 10. The water that flows into the downstream portion 152 is discharged from the lower end of the downstream portion 152 .

[0024] The second rib 160 is provided below the upstream portion 151 of the second drain groove 150. The second rib 160 protrudes from the back surface 12 of the housing 10 toward the wall surface WL. The upper surface of the second rib 160 is provided on the same plane as the lower side wall surface of the upstream portion 151 of the second drain groove 150. In this embodiment, the second rib 160 is provided from the left end to the right end of the upstream portion 151. The second rib 160 is provided above the storage groove 120 and the first drain groove 130. The second rib 160 has the function of blocking water that has entered between the back surface 12 and the wall surface WL and guiding it to the second drain groove 150.

[0025] 2, 4, and 5, the water flow path WT is indicated by a dashed arrow. Because the housing 10 of the electronic device 5 is fixed to an outdoor wall WL, water may enter between the rear surface 12 of the housing 10 and the wall WL, for example, during rainy weather. In this embodiment, as shown in FIG. 2, the upper edge 46 of the opening 45 provided in the fixing member 40 is inclined downward to the right, so that water that enters between the rear surface 12 and the wall WL flows along the upper edge 46 and is guided to the right edge 49 or the second drain groove 150. This reduces the amount of water that adheres to the cable 30.

[0026] 2 and 4, a second rib 160 is provided below the upper edge 46 of the opening 45, so that water that flows below the upper edge 46 of the opening 45 is blocked by the upper surface of the second rib 160. Because the upper surface of the second rib 160 is inclined downward to the right, the water blocked by the upper surface of the second rib 160 is guided into the second drain groove 150. This makes it possible to further reduce the amount of water that adheres to the cable 30.

[0027] Because the downstream portion 152 of the second drain groove 150 extends parallel to the direction of gravity G, water that flows into the downstream portion 152 of the second drain groove 150 easily flows to the lower end of the second drain groove 150. Therefore, water that flows into the second drain groove 150 can be quickly drained from the lower end of the second drain groove 150.

[0028] The upper end of the storage groove 120 is inclined downward to the right and is connected to the side wall surface of the first drain groove 130. Therefore, water that flows below the second rib 160 flows along the upper end of the storage groove 120 and is guided into the first drain groove 130. Therefore, the amount of water that flows into the storage groove 120 can be reduced, and the amount of water that adheres to the cable 30 can be reduced.

[0029] Because the first rib 140 is in contact with the cable 30 stored in the storage groove 120, water flowing downward along the cable 30 is blocked by the upper surface of the first rib 140. The upper surface of the first rib 140 is inclined downward to the right and is connected to the side wall surface of the first drain groove 130, so the water blocked by the upper surface of the first rib 140 is guided into the first drain groove 130. Therefore, the amount of water flowing along the cable 30 into the inlet 110 can be reduced.

[0030] Because the first drain groove 130 extends parallel to the direction of gravity G, water that flows into the first drain groove 130 tends to flow to the lower end of the first drain groove 130. Therefore, water that flows into the first drain groove 130 can be quickly drained from the lower end of the first drain groove 130.

[0031] 5, first rib 140 is in contact with lower edge 47 of opening 45 provided in fixing member 40, and first rib 140 has inclined surface 145 that slopes downward toward lower edge 47 of opening 45, so that some of the water blocked by the upper surface of first rib 140 is guided to lower edge 47 of opening 45. Therefore, the amount of water flowing along cable 30 into inlet 110 can be reduced.

[0032] As shown in FIG. 2 , the lower edge 47 of the opening 45 provided in the fixing member 40 has a portion that overlaps with the first rib 140 when viewed perpendicularly to the back surface 12, a portion that overlaps with the first drain groove 130 when viewed perpendicularly to the back surface 12, and a portion that overlaps with the second drain groove 150 when viewed perpendicularly to the back surface 12. In addition, the lower edge 47 of the opening 45 is inclined downward to the right from the first rib 140 toward the first drain groove 130 and the second drain groove 150. Therefore, water that has trickled from the inclined surface 145 of the first rib 140 to the lower edge 47 of the opening 45 is guided to the first drain groove 130 and the second drain groove 150. Therefore, water that has trickled to the lower edge 47 of the opening 45 can be effectively drained from the first drain groove 130 and the second drain groove 150.

[0033] 4, cable 30 extends diagonally downward along storage groove 120, then turns back upward at the lower left and is introduced into inlet 110. This prevents water that has flowed along cable 30 below first rib 140 from entering the interior of housing 10 through inlet 110. In addition, the lower end of storage groove 120 communicates with the external space below housing 10. Therefore, even if water flows into storage groove 120 below first rib 140, the water can be discharged from the lower end of storage groove 120.

[0034] According to the housing 10 of the present embodiment described above, it is possible to prevent water from entering the housing 10 along the cable 30. In other words, it is possible to improve the waterproofness of the housing 10. In particular, in this embodiment, the structure of the housing 10 and the structure of the fixing member 40 prevent water from entering the housing 10 along the cable 30. Therefore, it is possible to prevent water from entering the housing 10 from the inlet 110 without applying a sealant to the inlet 110 or providing a waterproof rubber member, and therefore it is possible to prevent an increase in the number of parts of the electronic device 5 and complicated installation work in order to improve the waterproofness of the housing 10.

[0035] B. Second embodiment: 6 is a rear view of the housing 10b in the second embodiment. In the second embodiment, the arrangement of the storage groove 120, the first drain groove 130, and the first rib 140 differs from that of the first embodiment. The other configurations are the same as those of the first embodiment unless otherwise specified.

[0036] In this embodiment, the storage groove 120 has a portion that extends vertically and a portion that extends obliquely from the lower end of the vertically extending portion toward the inlet 110. The first drain groove 130 extends vertically. The upper end of the first drain groove 130 is connected to the lower end of the vertically extending portion of the storage groove 120. The first drain groove 130 and the vertically extending portion of the storage groove 120 are aligned in a straight line. The first rib 140 protrudes from the lower side wall surface toward the upper side wall surface of the diagonally extending portion of the storage groove 120. The right side surface of the first rib 140 is flush with the side wall surface of the first drain groove 130. Water flowing along the cable 30 is blocked by the right side surface of the first rib 140 and guided into the first drain groove 130.

[0037] According to the housing 10b of this embodiment described above, it is possible to prevent water from entering the inside of the housing 10b along the cable 30.

[0038] C. Third embodiment: 7 is a rear view of the housing 10c in the third embodiment. The third embodiment differs from the first embodiment in that the housing 10c is provided with two first ribs 140A, 140B and two first drainage grooves 130A, 130B. The other configurations are the same as those in the first embodiment unless otherwise specified.

[0039] The first first rib 140A protrudes from the left side wall surface toward the right side wall surface of the storage groove 120. Water blocked by the first rib 140A is guided to the first first drain groove 130A provided near the first rib 140A.

[0040] The second first rib 140B is provided below the first first rib 140A and protrudes from the right side wall surface toward the left side wall surface of the storage groove 120. Water blocked by the first rib 140B is guided to the second first drain groove 130B provided near the first rib 140B.

[0041] According to the housing 10c of this embodiment described above, two first ribs 140A, 140B and two first drainage grooves 130A, 130B are provided, so that water can be prevented from entering the inside of the housing 10c along the cable 30 more effectively than in the first embodiment.

[0042] D. Fourth embodiment: 8 is a rear view of the housing 10d in the fourth embodiment. The fourth embodiment differs from the first embodiment in that the storage groove 120 is curved and that two first ribs 140A and 140B are provided on the housing 10d. The other configurations are the same as those in the first embodiment unless otherwise specified.

[0043] In this embodiment, storage groove 120 has a portion that extends vertically, a portion that extends diagonally upward and left from the lower end of the vertically extending portion, and a portion that extends diagonally downward and left from the left end of the diagonally upward and left portion toward inlet 110. The upper end of first drainage groove 130 communicates with the lower end of the vertically extending portion of storage groove 120. First drainage groove 130 and the vertically extending portion of storage groove 120 are arranged on a straight line.

[0044] The first rib 140A protrudes from the upper side wall surface toward the lower side wall surface of the upper and lower side wall surfaces of the portion of the storage groove 120 that extends diagonally upward to the left. The right side surface of the first rib 140A is provided on the same plane as the left side wall surface of the portion that extends up and down of the storage groove 120. Water flowing along the cable 30 is blocked by the right side surface of the first rib 140A and is guided into the first drain groove 130.

[0045] The second first rib 140B protrudes from the right side wall surface toward the left side wall surface of the left and right side wall surfaces of the portion of the storage groove 120 that extends diagonally downward and left. The upper surface of the first rib 140B is provided on the same plane as the lower side wall surface of the portion of the storage groove 120 that extends diagonally upward and left. Water flowing along the cable 30 is blocked by the upper surface of the first rib 140B and is guided to the first drain groove 130 through the portion of the storage groove 120 that extends diagonally upward and left.

[0046] According to the housing 10d of this embodiment described above, two first ribs 140A, 140B are provided, so that water can be prevented from entering the inside of the housing 10d along the cable 30 more effectively than in the first embodiment.

[0047] E. Other Embodiments: (E1) Fig. 9 is a cross-sectional view of a first rib 140 in another embodiment. As shown in Fig. 5, in the first embodiment, the cross-sectional shape of the first rib 140 is a pentagon having an inclined surface 145. In contrast, as shown in Fig. 9, the cross-sectional shape of the first rib 140 may be a triangle having an inclined surface 145. Alternatively, the cross-sectional shape of the first rib 140 may be a rectangle without an inclined surface 145.

[0048] (E2) In each of the above-described embodiments, the housings 10 to 10d are configured in a rectangular parallelepiped shape. However, the housings 10 to 10d may be configured in a triangular prism shape, for example. In this case, the housings 10 to 10d may not have a front face 11, and the top face 13 and bottom face 14 may be configured in a triangular shape, with the left side face 15 and right side face 16 connected. Alternatively, the housings 10 to 10d may be configured in a semicylindrical shape. In this case, the top face 13 and bottom face 14 may be configured in a semicircular shape, and the front face 11, left side face 15, and right side face 16 may be configured as a single curved surface.

[0049] (E3) In each of the above-described embodiments, the housings 10 to 10d have the second drainage grooves 150 and the second ribs 160. However, the housings 10 to 10d do not necessarily have at least one of the second drainage grooves 150 and the second ribs 160.

[0050] (E4) In the first embodiment described above, the upper surface of the first rib 140 is inclined with respect to the horizontal plane. However, the upper surface of the first rib 140 may be parallel to the horizontal plane. In this case, too, the first rib 140 can block water running down the cable 30, thereby preventing water from entering the housing 10.

[0051] (E5) In each of the above-described embodiments, the lower edge 47 of the opening 45 provided in the fixing member 40 is inclined with respect to the horizontal plane. In contrast, the lower edge 47 of the opening 45 provided in the fixing member 40 may be parallel to the horizontal plane.

[0052] (E6) In each of the above-described embodiments, the lower edge 47 of the opening 45 provided in the fixing member 40 may have an inclined surface that is inclined so that the position becomes lower as it approaches the wall surface WL. In this case, water that flows onto the lower edge 47 from the first rib 140 can be guided to the wall surface WL.

[0053] (E7) In each of the above-described embodiments, the housings 10 to 10d are fixed to an outdoor wall WL. However, the housings 10 to 10d may be fixed to an indoor wall where water may adhere to the cable 30, such as in a kitchen or bathroom.

[0054] (E8) In the electronic device 5 of the above-described embodiment, the housing 10 is fixed to the wall surface WL via the fixing member 40. However, the housing 10 may be fixed to the wall surface WL without using the fixing member 40.
