[0008] In some cases, a first connector for supplying power to a fan is provided on a first housing member, and a second connector for supplying power via the first connector to the fan is provided on a second housing member. In this case, the first connector provided on the first housing member and the second connector provided on the second housing member must be mated, which can make assembly work complicated. The present disclosure proposes a housing and an electronic device that can simplify assembly work.

[0009] FIG. 1 is an exploded perspective view of an electronic device 10 according to an embodiment. The electronic device 10 is a numerical control device, but is not limited to this. The electronic device 10 is installed in an industrial machine (not shown). The industrial machine may be a machining center, a lathe, an electric discharge machine, or the like. The electronic device 10 includes a housing 12, an electronic circuit board (heat generating element) 14, and a fan 16.

[0010] The housing 12 includes a first housing member (first outer shell member) 18 and a second housing member (second outer shell member) 20. The electronic circuit board 14 is fixed to the first housing member 18. The fan 16 is fixed to the second housing member 20. The first housing member 18 and the second housing member 20 are combinable. The housing 12 is configured by combining the first housing member 18 and the second housing member 20. When the first housing member 18 and the second housing member 20 are combined, the housing 12 is formed, for example, in a substantially rectangular parallelepiped shape. When the first housing member 18 and the second housing member 20 are combined, the fan 16 fixed to the second housing member 20 and the electronic circuit board 14 fixed to the first housing member 18 are electrically connected by wiring, connectors, etc. (not shown).

[0011] The first housing member 18 has a main surface (bottom surface, lower surface) 22, a first side surface 24, a second side surface 26, a third side surface 28, and a fourth side surface 30. The second side surface 26 and the third side surface 28 are each arranged along the short-side direction D1 of the housing 12. The second side surface 26 is located opposite the third side surface 28. The first side surface 24 and the fourth side surface 30 are each arranged along the long-side direction D2 of the housing 12. The fourth side surface 30 is located opposite the first side surface 24. A connector connection opening 32 for connecting connectors is formed in the fourth side surface 30. A plurality of external connection connectors 34 are located in the connector connection opening 32. An external device (not shown) can be connected to the external connection connectors 34 via a cable (not shown). In the example of FIG. 1 , four external connection connectors 34 are provided, but this is not limiting. Alternatively, the connector connection opening 32 may not be formed, and the external connection connectors 34 may not be provided.

[0012] The second housing member 20 has a main surface (top surface, upper surface) 36 and ventilation passages 38 (38A, 38B). In FIG. 1, two ventilation passages 38A, 38B are provided, but one of the two ventilation passages 38A, 38B may be omitted. In this case, there is only one ventilation passage 38. The ventilation passages 38A, 38B communicate with the interior of the housing 12 via ventilation openings 42A, 42B, respectively, and reach an outer peripheral edge 44 of the main surface 36. The ventilation passage 38 is defined by recesses 46 (46A, 46B).

[0013] The recess 46 is formed in the main surface 36. The recess 46 extends in a direction along the short-side direction D1 of the housing 12. One end of the recess 46A is connected to the vent 42A. The other end of the recess 46A reaches the outer peripheral edge 44 of the main surface 36. One end of the recess 46B is connected to the vent 42B. The other end of the recess 46B reaches the outer peripheral edge 44 of the main surface 36. A bottom surface 48 of the recess 46 is lower than an outer surface 50 of the main surface 36. The vent 42 is located between the bottom surface 48 of the recess 46 and the outer surface 50 of the main surface 36. The vent 42 is formed at the end of a side surface 52 of the recess 46 in the direction in which the recess 46 extends. The side surface 52 is aligned along the thickness direction D3 of the housing 12, but is not limited to this.

[0014] The electronic circuit board 14 is fixed to the first housing member 18 and accommodated inside the housing 12. A plurality of electronic components are mounted on a main surface 54 of the electronic circuit board 14. The electronic components include the external connection connector 34, a fan connection connector 56, and a control circuit 58 for controlling the industrial machine. The fan connection connector 56 includes a terminal for supplying power to the fan 16 and a terminal for inputting and outputting signals to and from the fan 16.

[0015] The base end surface of the fan connection connector 56 is fixed to the main surface 54 of the electronic circuit board 14. The tip surface 56P of the fan connection connector 56 faces the main surface 36 of the second housing member 20 when the first housing member 18 and the second housing member 20 are combined together. The direction from the base end surface of the fan connection connector 56 toward the tip surface 56P of the fan connection connector 56 is along the thickness direction D3 of the housing 12. The direction from the base end surface of the fan connection connector 56 toward the tip surface 56P of the fan connection connector 56 coincides with the direction from the main surface 22 of the first housing member 18 toward the fan connection connector 56.

[0016] As shown in Figure 2, the fan 16 is an axial flow fan. The fan 16 has a fan body 60, a fan frame 62, and a fan connector 64. The fan body 60 has a rotating shaft 66 and a plurality of fan blades 68. The fan blades 68 rotate in response to rotation of the rotating shaft 66. The fan frame 62 is arranged to surround the sides of the plurality of fan blades 68. The fan connector 64 is connected to the fan body 60 via wiring 69. The fan connector 64 is formed to be able to fit into the fan connector 56 (Figure 1).

[0017] A plurality of insertion openings 70 are formed in the fan frame 62. Each of the plurality of insertion openings 70 extends in a direction along the rotation axis 66. In Fig. 2, the insertion openings 70 are through-holes that penetrate the fan frame 62, but the present invention is not limited to this. Also, in Fig. 2, the number of the plurality of insertion openings 70 is four, but the present invention is not limited to this.

[0018] The housing 12 of this embodiment further includes a positioning mechanism 72 (FIG. 1), a fan mounting mechanism 74 (FIG. 2), and a connector mounting mechanism 76 (FIG. 2).

[0019] The positioning mechanism 72 ( FIG. 1 ) includes a plurality of receiving portions 78 and a plurality of protruding portions 80. The plurality of receiving portions 78 are provided, for example, on the first housing member 18. The plurality of protruding portions 80 are provided, for example, on the second housing member 20. The plurality of receiving portions 78 and the plurality of protruding portions 80 correspond one-to-one to each other. The plurality of receiving portions 78 and the plurality of protruding portions 80 are arranged at positions where they overlap with each other in the thickness direction D3 of the housing 12.

[0020] The multiple receptacles 78 are provided in an accommodating space of the first housing member 18 that accommodates the electronic circuit board 14. In FIG. 1 , the multiple receptacles 78 are appropriately provided on the outer circumferential edge 23 of the first housing member 18. The multiple receptacles 78 include a first receptacle 78A, a second receptacle 78B, a third receptacle 78C, and a fourth receptacle 78D. The first receptacle 78A is provided on the first outer circumferential edge 23A. The second receptacle 78B is provided on the second outer circumferential edge 23B. The third receptacle 78C and the fourth receptacle 78D are provided on the third outer circumferential edge 23C.

[0021] As shown in Fig. 3, each of the multiple receiving portions 78 has a frame wall 82 and a pair of frame wall guides 84. Fig. 3 shows a first receiving portion 78A of the multiple receiving portions 78. The frame wall 82 protrudes from the main surface 22 of the first housing member 18 along the first side surface 24. The frame wall 82 is a wall that forms an accommodating opening 88 for accommodating the protrusion 80. The accommodating opening 88 extends in a direction along the thickness direction D3 of the housing 12.

[0022] A notch 86 is formed in the frame wall 82. The notch 86 is located between the first side surface 24 and the pair of frame wall guides 84. An end surface 82F of the frame wall 82 formed by the notch 86 is lower than a tip surface 86F of the frame wall 82.

[0023] The pair of frame wall guides 84 are arranged at a distance from each other along the longitudinal direction D2 of the housing 12. The pair of frame wall guides 84 have guide surfaces 90 that guide the protrusions 80 into the accommodating openings 88. The guide surfaces 90 are inclined so as to become lower as they approach the first side surface 24. The accommodating openings 88 are located between the guide surfaces 90 and the first side surface 24. The dimension from the main surface 22 of the first housing member 18 to the end surface 82F of the frame wall 82 is the same as the dimension from the main surface 22 of the first housing member 18 to the lower end 90F of the guide surface 90.

[0024] As shown in Fig. 1 , a plurality of protrusions 80 protrude from the main surface 36 of the second housing member 20. The plurality of protrusions 80 are formed in a plate shape, but are not limited to this. The plurality of protrusions 80 are provided at positions corresponding to the plurality of receiving portions 78 provided on the second housing member 20. In Fig. 1 , the plurality of protrusions 80 are provided along the outer peripheral edge 44 of the main surface 36.

[0025] The multiple protrusions 80 include a first protrusion 80A, a second protrusion 80B, a third protrusion 80C, and a fourth protrusion 80D. The first protrusion 80A is provided on the first outer peripheral edge 44A corresponding to the first side surface 24 (first outer peripheral edge 23A). The second protrusion 80B is provided on the second outer peripheral edge 44B corresponding to the second side surface 26 (second outer peripheral edge 23B). The third protrusion 80C and the fourth protrusion 80D are provided on the third outer peripheral edge 44C corresponding to the third side surface 28 (third outer peripheral edge 23C).

[0026] 2, the fan mounting mechanism 74 is provided on the second housing member 20. Specifically, the fan mounting mechanism 74 is provided in a fan mounting area AR on the inner side surface 91 of the main surface 36.

[0027] The fan mounting area AR is an area where the fan 16 is mounted. The fan mounting area AR is formed in a shape corresponding to the shape of the fan 16. In FIG. 2 , the fan mounting area AR is formed in a rectangular shape, but is not limited to this. The fan mounting area AR is disposed between the air vent 42A and the air vent 42B. Although not shown, when there is one air passage 38, there is one air vent 42. In this case, the fan mounting area AR is disposed adjacent to one air vent 42.

[0028] The fan mounting mechanism 74 has a plurality of pillars 92 and a fan locking portion 94. The pillars 92 protrude from the main surface 36 of the second housing member 20. The pillars 92 correspond to the insertion openings 70 formed in the fan frame 62. The pillars 92 are inserted into the insertion openings 70, respectively. The pillars 92 include a pair of first pillars 92X and a pair of second pillars 92Y. The pair of first pillars 92X are arranged at diagonal corners (first diagonal) of the fan mounting area AR. The pair of second pillars 92Y are arranged at diagonal corners (second diagonal) of the fan mounting area AR. The dimension from the inner surface 91 to the protruding end of the first pillars 92X is greater than the dimension from the inner surface 91 to the protruding end of the second pillars 92Y.

[0029] The fan locking portion 94 protrudes from the main surface 36 of the second housing member 20. As shown in FIG. 2 , for example, a pair of fan locking portions 94 may be provided. A first fan locking portion 94X, which is one of the pair of fan locking portions 94, and a second fan locking portion 94Y, which is the other of the pair of fan locking portions 94, face each other. The number of fan locking portions 94 may be one, or three or more. For example, when there is one fan locking portion 94, the fan locking portion 94 is provided so as to surround the fan mounting area AR excluding the air vent 42.

[0030] An engagement claw 96 is formed in a portion of the fan locking portion 94 between the base end and the protruding end. As shown in FIG. 4 , when each of the multiple columnar portions 92 is inserted into the insertion opening 70 of the fan 16, the engagement claw 96 engages with the fan 16. This causes the fan locking portion 94 to lock the fan 16, and the fan 16 is fixed to the main surface 36 of the second housing member 20. In FIG. 4 , the engagement claw 96 engages with the end surface of the fan 16 in the direction in which the rotation shaft 66 extends, but this is not limiting. For example, the engagement claw 96 may engage with a recessed portion formed in the side surface of the fan frame 62.

[0031] 2, the connector mounting mechanism 76 is provided on the second housing member 20. Specifically, the connector mounting mechanism 76 is provided on a portion of the inner surface 91 of the main surface 36 of the second housing member 20 that is outside the fan mounting area AR. The connector mounting mechanism 76 is located near the fan mounting area AR.

[0032] As shown in FIG. 5 , the connector mounting mechanism 76 has a base portion 100, a connector placement portion 102, and a pair of connector locking portions 104. The base portion 100 serves as a seat on which the fan connector 64 ( FIG. 2 ) is placed. The base portion 100 protrudes from the inner surface 91. A wiring opening 106 is formed in the base portion 100. The wiring opening 106 is formed to allow the insertion of wiring 69 ( FIG. 2 ) that connects the fan connector 64 placed on the base portion 100 to the fan body 60 of the fan 16 mounted in the fan mounting mechanism 74.

[0033] The connector arrangement portion 102 is composed of a first wall 102A, a second wall 102B, and a third wall 102C. The first wall 102A, the second wall 102B, and the third wall 102C extend upward from the base portion 100. The second wall 102B and the third wall 102C face each other across the wiring opening 106. The first wall 102A is spaced apart from the second wall 102B and the third wall 102C in the direction along the wiring opening 106. The space between the first wall 102A, the second wall 102B, and the third wall 102C in the direction along the wiring opening 106 forms an arrangement space AS in which the fan connector 64 can be arranged.

[0034] [Correction based on Rule 91, April 25, 2025] A pair of connector locking portions 104 protrude from the inner surface 91. An arrangement space AS is located between the pair of connector locking portions 104. An engagement claw 108 is formed on each of the pair of connector locking portions 104. The engagement claw 108 is located between the base end and the protruding end of the connector locking portion 104. As shown in FIG. 6 , when the fan connector 64 is placed on the base portion 100 between the pair of connector locking portions 104, the engagement claw 108 engages with the fan connector 64. As a result, the pair of connector locking portions 104 lock the fan connector 64, and the fan connector 64 is fixed.

[0035] When the fan connector 64 is fixed, the base end surface of the fan connector 64 contacts the base portion 100. The direction from the base end surface of the fan connector 64 toward the tip surface 64P of the fan connector 64 is along the thickness direction D3 of the housing 12. The direction from the base end surface of the fan connector 64 toward the tip surface 64P of the fan connector 64 coincides with the direction from the inner surface 91 ( FIG. 5 ) of the second housing member 20 toward the fan connector 64.

[0036] Next, the attachment process for combining the first housing member 18 and the second housing member 20 will be described with reference to Figures 7 to 9. Figures 7 to 9 each schematically show the fan connector 56, the fan connector 64, the connector attachment mechanism 76, and the like.

[0037] As shown in Fig. 1, the electronic circuit board 14 is pre-fixed to the first housing member 18. Also, as shown in Fig. 4, the fan 16 is pre-mounted to the fan mounting mechanism 74 of the second housing member 20. That is, the fan 16 is pre-fixed to the second housing member 20. Also, as shown in Fig. 6, the fan connector 64 is pre-mounted to the connector mounting mechanism 76 of the second housing member 20. That is, the fan connector 64 is pre-fixed to the second housing member 20.

[0038] Next, the mounting process is performed. The mounting process is performed by a robot or an operator. First, the outer peripheral edge 44 of the second housing member 20 ( FIG. 1 ) is brought close to one of the first side surface 24, the second side surface 26, and the third side surface 28 of the first housing member 18 ( FIG. 1 ). The following describes an example in which the first outer peripheral edge 44A of the second housing member 20 is brought close to the first side surface 24 of the first housing member 18.

[0039] As shown in Fig. 7 , the protruding end of the first protruding portion 80A abuts against a guide surface 90 of a frame wall guide 84 provided in the first receiving portion 78A corresponding to the first protruding portion 80A. In the example of Fig. 7 , the protruding end of the first protruding portion 80A abuts against the guide surface 90 in a state in which the main surface 36 of the second housing member 20 is inclined with respect to the main surface 22 of the first housing member 18, but this is not limiting.

[0040] When the protruding end of the first protrusion 80A is abutted against the guide surface 90, if the second housing member 20 is brought further closer to the first housing member 18, the first protrusion 80A is guided by the guide surface 90 into the storage opening 88 in the frame wall 82.

[0041] 8, the protruding end of the first protrusion 80A reaches the housing opening 88. When the main surface 36 of the second housing member 20 is inclined with respect to the main surface 22 of the first housing member 18, the protruding end of the first protrusion 80A abuts against the inner wall surface of the frame wall 82. In this state, the tip surface 56P of the fan connection connector 56 and the tip surface 64P of the fan connector 64 are spaced apart and do not face each other.

[0042] 9, when the first housing member 18 and the second housing member 20 are brought closer together, the frame wall 82 forcibly corrects the orientation of the first protrusion 80A to the thickness direction D3 of the housing 12. As a result, the tip surface 56P of the fan connection connector 56 and the tip surface 64P of the fan connector 64 face each other.

[0043] In this way, by bringing the first housing member 18 and the second housing member 20 closer to each other, the orientation of the first protrusion 80A inserted into the first receiving portion 78A can be corrected to the thickness direction D3 of the housing 12. Therefore, even if the main surface 36 of the second housing member 20 is inclined with respect to the main surface 22 of the first housing member 18, the attachment process can ensure good mating of the fan connector 64 with the fan connection connector 56.

[0044] The same applies to the case where the second outer peripheral edge 44B of the second housing member 20 is brought close to the second side surface 26 of the first housing member 18. The same applies to the case where the third outer peripheral edge 44C of the second housing member 20 is brought close to the third side surface 28 of the first housing member 18. That is, the fan connector 64 can be satisfactorily fitted into the fan connection connector 56 regardless of whether the protrusion 80 provided on any of the first outer peripheral edge 44A, second outer peripheral edge 44B, and third outer peripheral edge 44C is inserted into the corresponding receiving portion 78.

[0045] As described above, the housing 12 of this embodiment is formed by combining the first housing member 18 and the second housing member 20. The fan connection connector 56 is fixed to the first housing member 18 via the electronic circuit board 14. The fan 16 is fixed to the second housing member 20 by the fan mounting mechanism 74, and the fan connector 64 is fixed to the second housing member 20 by the connector mounting mechanism 76.

[0046] As a result, by combining the first housing member 18 and the second housing member 20, the fan connector 56 and the fan connector 64 can be fitted together satisfactorily without lengthening the wiring 69 of the fan 16.

[0047] Specifically, the first housing member 18 and the second housing member 20 are attached to each other by bringing the first housing member 18 and the second housing member 20 close to each other in a direction normal to the main surface 22 of the first housing member 18 (thickness direction D3 of the housing 12), and the fan connector 64 is fitted into the fan connector 56. In other words, the step of attaching the first housing member 18 and the second housing member 20 also serves as the step of fitting the fan connector 56 and the fan connector 64.

[0048] In this embodiment, the receiving portion 78 is provided on the first housing member 18, and the protruding portion 80 that is received in the receiving portion 78 is provided on the second housing member 20. This allows the relative positions of the first housing member 18 and the second housing member 20 to be aligned.

[0049] Furthermore, the receiving portion 78 is provided with a guide surface 90 that guides the protrusion 80 into the receiving portion 78. This makes it possible to easily align the first housing member 18 and the second housing member 20 with each other.

[0050] (Modification of the embodiment) In the above embodiment, the air passage 38 is formed on the main surface 36 of the second housing member 20, but it may be formed on the main surface 22 of the first housing member 18. In this case, although not shown, the electronic circuit board 14 may be disposed in a location excluding the fan mounting area AR.

[0051] Furthermore, in the above embodiment, the case where there is one electronic circuit board 14 has been described as an example, but a plurality of electronic circuit boards 14 may be provided.

[0052] Furthermore, the multiple receiving portions 78 may be provided one each on the first side surface 24, the second side surface 26, and the third side surface 28. If the connector connection opening 32 is not formed on the fourth side surface 30, one or more receiving portions 78 may be provided on the fourth side surface 30. Furthermore, there may be only one receiving portion 78. In this case, one receiving portion 78 is provided on, for example, one of the first side surface 24, the second side surface 26, or the third side surface 28. If the connector connection opening 32 is not formed on the fourth side surface 30, one receiving portion 78 may be provided on the fourth side surface 30.

[0053] Furthermore, although multiple receiving portions 78 are provided on the first housing member 18 and multiple protrusions 80 are provided on the second housing member 20, multiple receiving portions 78 may also be provided on the second housing member 20 and multiple protrusions 80 may also be provided on the first housing member 18.

[0054] Effect of the Embodiment As described above, the present embodiment includes the first housing member 18 to which the first connector (fan connection connector 56) for supplying power to the fan 16 is fixed, and the second housing member 20 that is attached to the first housing member 18 and to which the fan 16 is fixed. The second housing member 20 is provided with a connector mounting mechanism 76 for fixing the second connector (fan connector 64) that is connected to the fan 16 via wiring 69 and that fits into the first connector (fan connection connector 56).

[0055] As a result, by combining the first housing member 18 and the second housing member 20, the first connector and the second connector can be easily fitted together without lengthening the wiring 69 of the fan 16.
