Description

[Technical Field]

[0001] The present invention relates to a board housing case that houses and protects boards that control various electronic devices. [Background technology]

[0002] Conventionally, circuit boards (computers) that control various electronic devices are protected by a housing (case), but various cables must be connected to the circuit board inside the housing, such as cables for exchanging signals with other (external) devices to be controlled and cables for supplying power to the circuit board. For this reason, the housing must be formed with receptacles (connection ports) for connecting the ends (terminals) of these cables to connectors provided on the circuit board. However, forming a receptacle in the housing exposes the connector to the outside, which creates the problem of not being able to adequately protect the connector and circuit board from the adhesion or intrusion of foreign matter or external forces. On the other hand, Patent Document 1 discloses a board case with a connector cover. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5842052 Summary of the Invention [Problem to be solved by the invention]

[0004] Patent Document 1 aims to protect the circuit board from unauthorized access, etc., by reducing the effort required to fasten the connector cover while providing a structure in which the connector cover cannot be easily removed. In this circuit board case with connector cover, the connector is covered by the connector cover, so the connector can be protected to a certain extent from the adhesion or intrusion of foreign matter, external forces, etc. However, the connector cover does not seal the connector, and no consideration is given to preventing water from entering the connector cover (case). In other words, Patent Document 1 does not anticipate that the circuit board case with connector cover will be installed or used outdoors, and if it is exposed to rain and wind outdoors, it will not be able to protect the connector and circuit board, resulting in a problem of limiting the places (applications) in which it can be used.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a circuit board storage case that can protect circuit boards from rain and wind even when used outdoors and can reliably control various electronic devices. [Means for solving the problem]

[0006] A board housing case according to the present invention that meets the above-mentioned object is a board housing case that houses a board to be connected to one or more cables, The device comprises a case body that holds the board, and a cover body that is detachably attached to the case body and covers the board, and one longitudinal side of one or more cables connected to the board is clamped between the case body and the cover body, holding them in a waterproof state.

[0007] In the substrate storage case of the present invention, it is preferable that the case has one or more cable insertion holes formed opposite a case side cutout portion formed in the case body and a cover side cutout portion formed in the cover body, and that a water-stopping material is attached to the contact surface between the case body and the cover body and to the inner surface of the one or more cable insertion holes.

[0008] In the board storage case of the present invention, the case main body has a board storage section that stores the board and a cable holding section that holds one longitudinal side of one or more of the cables connected to the board, and a partition plate that separates the case main body into the board storage section and the cable holding section is formed with one or more cable insertion ports corresponding to one or more connectors provided on the board, and it is preferable that the cover body is divided into a board side cover that covers the board storage section of the case main body and a cable side cover that covers the cable holding section of the case main body.

[0009] In the board housing case according to the present invention, the case body may be divided into the board housing portion and the cable holding portion.

[0010] In the substrate housing case according to the present invention, a plurality of ribs may be provided on the inner surface and / or the outer surface of the substrate housing portion of the case body.

[0011] In the substrate case according to the present invention, the plurality of ribs are preferably arranged in a honeycomb pattern.

[0012] The substrate storage case according to the present invention preferably includes a fastener for fastening the case body to another electronic device.

[0013] In the board housing case according to the present invention, the other electronic device may be a drone. [Effects of the Invention]

[0014] The circuit board storage case of the present invention is divided into a case body and a cover body, making it easy to connect cables to the circuit board, and the cables connected to the internal circuit board can be clamped between the case body and the cover body and kept in a waterproof state, thereby maintaining the waterproofness of the circuit board and enabling it to be used outdoors.

[0015] In the circuit board storage case of the present invention, there is one or more cable insertion holes formed by opposing case side cutouts formed in the case body and cover side cutouts formed in the cover body, and when a water-stopping material is attached to the contact surface between the case body and the cover body and the inner surface of the one or more cable insertion holes, simply by connecting one longitudinal side of the cable (tip terminal) to the circuit board and then attaching the cover body to the case body, the contact surface between the case body and the cover body and the cable insertion holes can be reliably waterproofed.

[0016] In the board storage case of the present invention, the case main body has a board storage section that stores the board and a cable holding section that holds one longitudinal side of one or more cables connected to the board, and a partition plate that separates the case main body into the board storage section and the cable holding section has one or more cable jacks that correspond to one or more connectors provided on the board, and when the cover body is divided into a board side cover that covers the board storage section of the case main body and a cable side cover that covers the cable holding section of the case main body, cables can be inserted and removed from the cable jacks without exposing the board by simply opening and closing the cable side cover alone, resulting in excellent safety and operability.

[0017] In the board storage case of the present invention, if the case main body is divided into a board storage section and a cable holding section, if waterproofing is not required, it can be used even with the cable holding section and cable side cover removed, thereby making it possible to make the board storage case smaller and lighter.

[0018] In the board storage case of the present invention, when multiple ribs are provided on the inner and / or outer surfaces of the board storage section of the case body, the board storage section can be made thinner and lighter, while the cooling effect during air cooling is improved by heat dissipation from the ribs, preventing heat from building up inside the case body and reducing the occurrence of malfunctions and failures of the board.

[0019] In the substrate case according to the present invention, when the plurality of ribs are arranged in a honeycomb pattern, the heat dissipation and durability of the case body can be improved.

[0020] In the board storage case of the present invention, if a fixing device for fixing the case body to another electronic device is provided, it becomes possible to move the board storage case while it is integrated with the other electronic device, improving handling and reducing the load on the cable.

[0021] In the circuit board housing case of the present invention, if the other electronic device is a drone, the circuit board can add various functions to the drone, expanding the uses of the drone. [Brief explanation of the drawings]

[0023] Next, embodiments of the present invention will be described with reference to the accompanying drawings to facilitate understanding of the present invention. The synthetic resin board storage case 10 according to the first embodiment of the present invention shown in Figures 1 to 5 stores and protects a board 11 that controls various electronic devices, and is waterproof. The board 11 stored in the board storage case 10 is connected to one or more (here, up to five) cables (not shown).

[0024] Here, a single-board computer equipped with a CPU, main memory, chipset, input / output terminals, etc. is preferably used as the board 11, but is not limited thereto, and the elements (modules) to be mounted are appropriately selected depending on the type, purpose, function, operation, etc. of the other (external) electronic device connected to the board 11. For example, if the other electronic device is a drone, it can support remote control, remote monitoring, AI inference processing, etc. of the drone. In addition, the cables include a power cable for supplying power to the board 11 and various cables (e.g., LAN cable, USB cable, etc.) for connecting the board 11 to the other (external) electronic device to be controlled and exchanging signals.

[0025] As shown in FIG. 5 , the board housing case 10 includes a case body 13 having an opening 12 on one side thereof for holding the board 11, and a cover body 14 detachably attached to the case body 13 to cover the board 11. One longitudinal side of one or more cables connected to the board 11 is sandwiched between the case body 13 and the cover body 14 and held in a waterproof state, while the other longitudinal side of the cable can be taken out of the board housing case 10. In this way, because the board housing case 10 is divided into the case body 13 and the cover body 14, it is easy to connect the cable to the board 11. Furthermore, by sandwiching the cable connected to the board 11 inside the board housing case 10 between the case body 13 and the cover body 14 and holding it in a waterproof state, the waterproofness of the board 11 is maintained, enabling outdoor use.

[0026] 5, the board housing case 10 has a plurality of (here, five) cable insertion holes 18 formed by case-side cutouts 16 formed in the case body 13 and cover-side cutouts 17 formed in the cover body 14 facing each other, and a waterproof material 19 is attached to the contact surface between the case body 13 and the cover body 14 and to the inner circumferential surface of each cable insertion hole 18. Therefore, after connecting one longitudinal end (the tip terminal) of the cable to the board 11, simply attaching the cover body 14 to the case body 13 can waterproof the contact surface between the case body 13 and the cover body 14 and the cable insertion holes 18. In particular, by attaching the waterproof material 19 along the contact surface between the case body 13 and the cover body 14 so as to cover the case-side cutouts 16 and the cover-side cutouts 17, the outer circumferential surface of the cable inserted into the cable insertion hole 18 can be brought into close contact with the waterproof material 19 covering the inner circumferential surface of the cable insertion hole 18, thereby maintaining the waterproofness of the entire board housing case 10.

[0027] For cable insertion holes 18 through which no cable is inserted, a water stop valve (not shown) having an outer diameter equal to the outer diameter of the cable can be inserted to prevent water from seeping in through cable insertion holes 18. Although the board housing case 10 of this embodiment has waterproof performance that complies with IP54, the waterproof performance is selected appropriately depending on the location where the board housing case 10 is used, and accordingly, the material and type of water stop material 19 and the water stopping method are also selected appropriately.

[0028] In this embodiment, as shown in Fig. 5, case body 13 has board accommodating section 22 that accommodates board 11 and cable holding section 23 that holds one longitudinal side of one or more cables connected to board 11. A partition plate 21 that separates case body 13 into board accommodating section 22 and cable holding section 23 has a plurality of (here, five) cable outlets 25 formed therein that correspond to a plurality of (here, five) connectors 24a to 24e provided on board 11. Cover body 14 is divided into board-side cover 26 that covers board accommodating section 22 of case body 13 and cable-side cover 27 that covers cable holding section 23 of case body 13. Therefore, by simply removing cable-side cover 27 alone, cable outlet 25 can be opened without exposing board 11 to the outside, as shown in Fig. 4, and thus cables can be easily inserted or removed, resulting in excellent safety and operability.

[0029] As shown in Fig. 3, a plurality of ribs 29 are provided on the outer surface of the substrate accommodating portion 22 of the case body 13 and arranged in a honeycomb pattern. This improves the heat dissipation of the case body 13, preventing heat from building up inside the substrate accommodating case 10 and reducing the occurrence of malfunctions and breakdowns of the substrate 11. It also reduces the thickness of the case body 13, thereby reducing its weight and improving its durability. The dimensions (length, height, and thickness) of each rib 29 are selected as appropriate, and the size (length of one side) of the honeycomb (hexagon) also changes accordingly. The arrangement of the ribs 29 is not limited to a honeycomb pattern and can be selected as appropriate.

[0030] 1 and 3 to 5, fasteners 30 for fastening the case body 13 and the cover body 14 (board-side cover 26 and cable-side cover 27) to another electronic device are provided on both sides (three locations on each side) of the board housing case 10. As shown in Figures 6(A) and 6(B), the fasteners 30 have band insertion portions 32 and 33 to which a fastening band 31 can be attached vertically and horizontally, and the band insertion portions 32 and / or the band insertion portions 33 are selected appropriately depending on the shape of the other electronic device and the attachment position of the board housing case 10 relative to the other electronic device.

[0031] In this embodiment, the fixture 30 is divided into a case-side fixing portion 34 formed on the case body 13 and a cover-side fixing portion 35 formed on the cover body 14 (board-side cover 26 and cable-side cover 27). Therefore, the cover body 14 (board-side cover 26 and cable-side cover 27) is attached to the case body 13, and the case-side fixing portion 34 and the cover-side fixing portion 35 are fastened with fixing screws 36, thereby functioning as the fixture 30. The method of fixing the case body 13 and the cover body 14 (board-side cover 26 and cable-side cover 27) may be selected as appropriate. Alternatively, a fixing device may be provided only on the case body, and the cover body (board-side cover and cable-side cover) may be detachable in a state where the case body is fixed to another electronic device by the fixing device.

[0032] 1, 2, 4, and 5, the substrate case 10 is equipped with an antenna 37 for wireless communication (LTE). This antenna 37 can be rotated in the horizontal and vertical planes as needed, but as shown in Figures 2 and 3, it can be folded so as to fit within (overlap with) the external shape of the substrate case 10 in plan view, making it highly compact. The shape (structure), number, arrangement, etc. of the antenna 37 can be selected as appropriate.

[0033] As shown in Figures 1, 2 and 5, a heat sink 38 is attached to the upper surface (outer surface) of the cover body 14 (substrate side cover 26), and the shape, number, size, arrangement, etc. of the heat sink 38 are selected appropriately depending on the type, shape, number, size, arrangement, etc. of the substrates 11 to be accommodated in the substrate accommodation case 10.

[0034] As shown in FIG. 5, the case body 13 is provided with a display unit 40 to which an LED lamp 39 is attached, a switch mounting hole 42 to which a power switch 41 is attached, and a vent mounting hole 44 to which a barometric vent 43 is attached to adjust pressure fluctuations inside the board storage case 10 and promote the release of water vapor to prevent condensation, but the arrangement of these can be selected as appropriate.

[0035] Next, a board storage case 10A according to a second embodiment of the present invention will be described with reference to Figures 7 to 11. Components similar to those in the first embodiment are designated by the same reference numerals and will not be described again. The board storage case 10A differs from the board storage case 10 in that the case body 13A is divided into a board storage section 22A and a cable holding section 23A, the board storage section 22A is formed in a plate shape, a partition plate 21 is provided on the board-side cover 26A, multiple ribs 29 are provided on the inner surface of the board storage section 22A, two types of fasteners 30A, 30B are provided for fastening the board storage section 22A of the case body 13A and the board-side cover 26A of the cover body 14A to another electronic device, and heat sinks 38A, 38B having multiple pin-shaped protrusions 45 resembling pin holders are attached to the board storage section 22A and the board-side cover 26A, respectively.

[0036] As shown in Fig. 10, case main body 13A is divided into board housing section 22A and cable holding section 23A, so that cable holding section 23A and cable side cover 27A can be removed from board housing case 10A shown in Fig. 7 and used as shown in Fig. 11. This makes it possible to reduce the size and weight of board housing case 10A when used indoors, or outdoors when there is no need to worry about it getting wet in the rain or the like and waterproofing is not required. For example, when board housing case 10A is mounted on a drone and used, the load on the drone can be reduced and the flying distance can be extended. Furthermore, even when the cable holding portion 23A and the cable side cover 27A are removed, the board 11 is not exposed to the outside, and the cable can be easily and reliably connected to the board 11 by simply inserting the cable into the cable insertion port 25 formed in the partition plate 21.

[0037] In this embodiment, the ribs 29 are provided on the inner surface side of the substrate accommodating portion 22A, thereby increasing the internal volume of the substrate accommodating case 10A. Furthermore, in the substrate storage case 10, band insertion portions 32 and 33 were formed on one fixture 30 to allow the fixing band 31 to be attached vertically and horizontally, but in the substrate storage case 10A, fixture 30A having only band insertion portion 32A to allow the fixing band 31 to be attached vertically, and fixture 30B having only band insertion portion 33A to allow the fixing band 31 to be attached horizontally are formed independently (separately), thereby simplifying the structure of fixtures 30A and 30B and reducing the external size of substrate storage case 10A. In this embodiment, band insertion portions 32A and 33A are formed so as to straddle substrate storage section 22A and substrate side cover 26A, so that substrate storage section 22A and substrate side cover 26A can be fixed simultaneously with fixing band 31. Furthermore, in this embodiment, a plurality of needle-like (pin-like) protrusions 45 are provided on the heat sinks 38A and 38B, thereby expanding the heat dissipation area and improving the cooling effect.

[0038] The above describes an embodiment of the present invention, but the present invention is not limited to the configurations described in the above embodiment, and also includes other embodiments and modifications that are possible within the scope of the matters described in the claims. The case body and cover body that make up the board housing case can be divided in various ways, and the shapes of each can be selected appropriately. Also, in all of the above embodiments, the cover body is divided into a board-side cover and a cable-side cover, but the board-side cover and the cable-side cover may be integrated, or, for example, the cable-side cover may be attached to the board-side cover so that it can be opened and closed without removing the cable-side cover, allowing the cable to be inserted and removed.
