The first control device 24A and the second control device 24B differ in the number of wires 39 connected to them. The number of wires 39 connected to the second control device 24B is greater than the number of wires 39 connected to the first control device 24A.
なお、本実施の形態では、第1制御装置24A、および第2制御装置24Bに接続される全ての配線39の断面積はほぼ等しいものとして説明する。しかしながら、複数の配線39は、断面積の異なる複数種類の配線を含んでいてもよい。
In this embodiment, the cross-sectional area of all the wirings 39 connected to the first control device 24A and the second control device 24B will be described as being approximately equal. However, the plurality of wirings 39 may include a plurality of types of wirings having different cross-sectional areas.
図8に示すように、側壁部41cは、電装品箱30の収容空間Aを下側から覆う。側壁部41cの先端は、蓋体50の板面51aに対向する。側壁部41cの上側には、蓋体50の第1リブ53aが重なる。側壁部41cの上面と第1リブ53aの下面とは、互いに接触していてもよい。
As shown in FIG. 8, the side wall portion 41c covers the housing space A of the electrical component box 30 from below. The tip of the side wall portion 41c faces the plate surface 51a of the lid 50. The first rib 53a of the lid body 50 overlaps the upper side of the side wall portion 41c. The upper surface of the side wall portion 41c and the lower surface of the first rib 53a may be in contact with each other.
本実施の形態の電装品箱30は、ケース40の側壁部41cの上側に蓋体50の第1リブ53aが重なることでケース40に蓋体50が組み付けられる。すなわち、蓋体50は、ケース40にインロー構造によって組み付けられる。このため、ケース40と蓋体との間の隙間を狭くすることができ、電装品箱30内への小動物の侵入を抑制できる。
In the electrical component box 30 of this embodiment, the lid 50 is assembled to the case 40 by overlapping the first rib 53a of the lid 50 with the upper side of the side wall 41c of the case 40. That is, the lid body 50 is assembled to the case 40 by a spigot structure. Therefore, the gap between the case 40 and the lid can be narrowed, and small animals can be prevented from entering the electrical component box 30.
図9に示すように、側壁部41cの切欠部45は、蓋体50側(すなわち右側)に開口する。切欠部45の内縁45aの一部は、第1リブ53aの先端部より、底板部41a側(すなわち左側)に配置される。また、第1リブ53aの蓋側切欠部54は、切欠部45の直上に配置される。
As shown in FIG. 9, the notch 45 of the side wall 41c opens on the lid 50 side (ie, on the right side). A part of the inner edge 45a of the notch 45 is located closer to the bottom plate 41a (ie, to the left) than the tip of the first rib 53a. Further, the lid side notch 54 of the first rib 53a is arranged directly above the notch 45.
側壁部41cの板厚方向(本実施の形態では鉛直方向Z)から見て、切欠部45の内縁45aと蓋側切欠部54の内縁54aとは、略矩形状の開口を形成する。切欠部45の内縁45aと蓋側切欠部54の内縁54aは、電装品箱30の収容空間Aを外部空間に連通させる配線出入口30aを構成する。
When viewed from the thickness direction of the side wall portion 41c (vertical direction Z in this embodiment), the inner edge 45a of the notch 45 and the inner edge 54a of the lid-side notch 54 form a substantially rectangular opening. The inner edge 45a of the notch 45 and the inner edge 54a of the lid-side notch 54 constitute a wiring entrance/exit 30a that communicates the storage space A of the electrical component box 30 with the external space.
複数の配線39は、切欠部45の内部に配置される。複数の配線39は、板バネ部60の接触部62に接触する。板バネ部60は、複数の配線39を切欠部45の内縁45aに押し当てる。これにより、板バネ部60は、配線39が切欠部45から離脱することを抑制する。さらに、板バネ部60は、配線39同士を接触させて配線39の間の隙間を最小にする。これにより、板バネ部60は、配線出入口30aを介する小動物、および埃の電装品箱30内への侵入を抑制する。
The plurality of wirings 39 are arranged inside the notch 45. The plurality of wires 39 contact the contact portion 62 of the leaf spring portion 60 . The leaf spring section 60 presses the plurality of wires 39 against the inner edge 45a of the cutout section 45. Thereby, the leaf spring section 60 suppresses the wiring 39 from separating from the notch section 45 . Further, the leaf spring portion 60 brings the wirings 39 into contact with each other to minimize the gap between the wirings 39. As a result, the leaf spring portion 60 prevents small animals and dust from entering the electrical component box 30 through the wiring entrance/exit 30a.
図8に示すように、板バネ部60は、接触部62において複数の配線39に接触する。また、板バネ部60は、複数の配線39を切欠部45の内縁45a側に押し当てるとともに、配線39から受ける反力によって蓋体50側(すなわち右側)に撓む。
As shown in FIG. 8, the leaf spring section 60 contacts the plurality of wirings 39 at the contact section 62. Further, the leaf spring portion 60 presses the plurality of wires 39 against the inner edge 45a side of the notch portion 45, and is bent toward the lid 50 (ie, to the right) by the reaction force received from the wires 39.
図8、および図9に示す第1制御装置24Aでは、配線出入口30aを通過する配線39の本数が比較的少ない。したがって、第1制御装置24Aにおける、板バネ部60のたわみ量は、比較的小さい。
一方で、図10、および図11に示す第2制御装置24Bでは、配線出入口30aを通過する配線39の本数が、第1制御装置24Aと比較して多い。したがって、第2制御装置24Bにおける、板バネ部60のたわみ量は、第1制御装置24Aと比較して大きくなる。 In thefirst control device 24A shown in FIGS. 8 and 9, the number of wires 39 passing through the wire entrance/exit 30a is relatively small. Therefore, the amount of deflection of the leaf spring section 60 in the first control device 24A is relatively small.
On the other hand, in thesecond control device 24B shown in FIGS. 10 and 11, the number of wires 39 passing through the wire entrance/exit 30a is larger than in the first control device 24A. Therefore, the amount of deflection of the leaf spring portion 60 in the second control device 24B is larger than that in the first control device 24A.
一方で、図10、および図11に示す第2制御装置24Bでは、配線出入口30aを通過する配線39の本数が、第1制御装置24Aと比較して多い。したがって、第2制御装置24Bにおける、板バネ部60のたわみ量は、第1制御装置24Aと比較して大きくなる。 In the
On the other hand, in the
本実施の形態において、切欠部45の開口面積、および板バネ部60の配置などは、想定される配線39の本数が最も少ない場合であっても、配線39と板バネ部60の接触が確保されるように設定される。したがって、板バネ部60は、如何なる機種の制御装置24においても、弾性部61において弾性変形する。これにより、板バネ部60が、複数の配線39を切欠部45の内縁45aに押し当てて、配線出入口30aに大きな隙間が生じることを抑制する。
In this embodiment, the opening area of the notch 45 and the arrangement of the leaf spring part 60 ensure contact between the wiring 39 and the leaf spring part 60 even when the expected number of wirings 39 is the smallest. is set so that Therefore, the leaf spring section 60 is elastically deformed in the elastic section 61 in any model of the control device 24. Thereby, the leaf spring portion 60 presses the plurality of wires 39 against the inner edge 45a of the notch portion 45, thereby suppressing the formation of a large gap at the wire entrance/exit 30a.
図8に示すように、本実施の形態の接触部62は、側壁部41cの下側に配置される。このため、配線39と板バネ部60との接触位置を、配線39と切欠部45内縁45aとの接触位置に対し、下側にずらして配置できる。これにより、配線39の一部位に左右両側から力が集中して付与されることを抑制できる。
As shown in FIG. 8, the contact portion 62 of this embodiment is arranged below the side wall portion 41c. Therefore, the contact position between the wiring 39 and the leaf spring portion 60 can be shifted downward with respect to the contact position between the wiring 39 and the inner edge 45a of the notch 45. Thereby, it is possible to prevent force from being concentrated and applied to one portion of the wiring 39 from both the left and right sides.
図8に示すように、本実施の形態の閉塞板部63は、側壁部41cの下側に配置される。また、図9に示すように、閉塞板部63は、側壁部41cの板厚方向から見て切欠部45と重なる。閉塞板部63は、配線出入口30aのうち、配線39が通過しない領域を閉塞する。
As shown in FIG. 8, the closing plate portion 63 of this embodiment is arranged below the side wall portion 41c. Further, as shown in FIG. 9, the closing plate portion 63 overlaps the notch portion 45 when viewed from the thickness direction of the side wall portion 41c. The closing plate portion 63 closes off a region of the wiring entrance/exit 30a through which the wiring 39 does not pass.
本実施の形態において、閉塞板部63の幅寸法D1は、切欠部45の開口幅D2よりも大きい。このため、閉塞板部63は、幅方向両側で側壁部41cに重なる。本実施の形態によれば、閉塞板部63が、側壁部41cの板厚方向一方側(下側)で側壁部41cに重なるように配置される。これにより、閉塞板部63を切欠部45の内部に配置する場合と比較して、閉塞板部63と側壁部41cとの間の隙間を小さくすることができ、電装品箱30の収容空間Aへの小動物の侵入を抑制できる。
In this embodiment, the width dimension D1 of the closing plate portion 63 is larger than the opening width D2 of the notch portion 45. Therefore, the closing plate portion 63 overlaps the side wall portion 41c on both sides in the width direction. According to this embodiment, the closing plate portion 63 is arranged so as to overlap the side wall portion 41c on one side (lower side) in the thickness direction of the side wall portion 41c. Thereby, compared to the case where the closing plate part 63 is arranged inside the notch part 45, the gap between the closing plate part 63 and the side wall part 41c can be made smaller, and the housing space A of the electrical component box 30 can be made smaller. It can prevent small animals from entering.
図10に示すように、第1リブ53aの蓋側切欠部54は、側壁部41cの板厚方向から見て切欠部45に重なる。蓋側切欠部54は、切欠部45を通過する配線39の本数が多い場合に、切欠部45の上側で配線39が第1リブ53aに干渉することを抑制する。このため、第1リブ53aとの干渉によって配線39が急激に折り曲げられるなど、配線39に大きな負荷が加わることを抑制できる。
As shown in FIG. 10, the lid-side notch 54 of the first rib 53a overlaps the notch 45 when viewed from the thickness direction of the side wall 41c. The lid side notch 54 prevents the wiring 39 from interfering with the first rib 53a above the notch 45 when the number of wirings 39 passing through the notch 45 is large. Therefore, it is possible to prevent a large load from being applied to the wiring 39, such as the wiring 39 being suddenly bent due to interference with the first rib 53a.
図3に示すように、本実施の形態の室内機20は、熱交換器22と、送風機23と、制御装置24と、熱交換器22、送風機23、および制御装置24を内部に収容する筐体21と、を備える。図8に示すように、制御装置24は、複数の配線39が接続される第1回路基板31、および第1回路基板31を収容する電装品箱30を有する。また、本実施の形態の電装品箱30は、第1回路基板31を囲む側壁部41cと、第1回路基板31を覆う蓋体50と、蓋体50に設けられる板バネ部60と、を有する。側壁部41cには、複数の配線39を通す切欠部45が設けられる。板バネ部60は、切欠部45の内縁45aに複数の配線39を押し当てる。

According to this embodiment, the plurality of wirings 39 are pressed against the inner edge 45a of the notch 45 by the leaf spring section 60. This can suppress the generation of large gaps between the inner edge 45a of the notch 45 and the plurality of wires 39, between the plurality of wires 39, and between the wires 39 and the leaf spring portion 60. As a result, small animals such as insects and dust can be prevented from entering the housing space A of the electrical component box 30 through the wiring entrance 30a.
本実施の形態の電装品箱30によれば、配線出入口30aの開口部面積(複数の配線39の通過を許容する面積、同じ)の大きさが、板バネ部60の弾性変形によって調整される。図8および図10に示すように、機種ごとに切欠部45を通過する配線39の本数が変わる場合でも、板バネ部60の弾性変形量が自動的に変わり開口部面積が適切に調整される。本実施の形態によれば、機種ごとに開口部面積を調整する部材を別途用意する必要がなく、複数の機種の室内機20に対し部品数の低減を図ることができる。
According to the electrical component box 30 of the present embodiment, the size of the opening area of the wiring entrance 30a (the same area that allows the passage of a plurality of wirings 39) is adjusted by elastic deformation of the leaf spring portion 60. . As shown in FIGS. 8 and 10, even if the number of wires 39 passing through the notch 45 changes depending on the model, the amount of elastic deformation of the leaf spring section 60 automatically changes and the opening area is adjusted appropriately. . According to the present embodiment, there is no need to separately prepare a member for adjusting the opening area for each model, and it is possible to reduce the number of parts for the indoor units 20 of a plurality of models.

本実施の形態において、蓋体50は、第1蓋部51と第2蓋部52とを有する。第1蓋部51は、板バネ部60と一体的に成形される。第1蓋部51には、第1蓋部51の板厚方向から見て板バネ部60と重なる孔部51hが設けられる。第2蓋部52は、第1蓋部51の外側の面を覆う。第2蓋部52は、孔部51hを閉塞する。
In this embodiment, the lid body 50 has a first lid part 51 and a second lid part 52. The first lid portion 51 is integrally molded with the leaf spring portion 60. The first lid part 51 is provided with a hole 51h that overlaps the leaf spring part 60 when viewed from the thickness direction of the first lid part 51. The second lid part 52 covers the outer surface of the first lid part 51. The second lid portion 52 closes the hole portion 51h.
本実施の形態によれば、第1蓋部51に板厚方向から見て重なる孔部51hを設けることで、第1蓋部51を樹脂成形によって製造する場合に、第1蓋部51の板厚方向を金型の割方向として、第1蓋部51、および板バネ部60を容易に成形できる。また、第1蓋部51をプレス加工によって製造する場合においても、第1蓋部51の板厚方向をプレス方向として、第1蓋部51、および板バネ部60を容易に成形できる。
According to this embodiment, by providing the first lid part 51 with the overlapping holes 51h when viewed from the plate thickness direction, when the first lid part 51 is manufactured by resin molding, the plate of the first lid part 51 can be The first lid portion 51 and the leaf spring portion 60 can be easily molded by setting the thickness direction as the cutting direction of the mold. Further, even when manufacturing the first lid part 51 by press working, the first lid part 51 and the leaf spring part 60 can be easily molded with the plate thickness direction of the first lid part 51 set as the pressing direction.
本実施の形態によれば、孔部51hが第2蓋部52によって閉塞されるため、孔部51hを介して電装品箱30の収容空間A側に小動物、および埃が侵入することを抑制できる。また、第2蓋部52が孔部51hを閉塞することで、図8に示すように、板バネ部60の変形方向には、第2蓋部52が配置される。このため、板バネ部60の弾性変形量は、閉塞板部63と第2蓋部52との間の隙間寸法以内に制限される。本実施の形態によれば、板バネ部60が、弾性領域を超えて塑性変形することを抑制することができる。したがって、組立時に切欠部45内の配線39が未整列であることによって、板バネ部60過剰な力が加わる場合などに、板バネ部60に損傷が生じることを抑制できる。
According to this embodiment, since the hole 51h is closed by the second lid 52, it is possible to suppress small animals and dust from entering the housing space A side of the electrical component box 30 through the hole 51h. . In addition, as the second lid portion 52 closes the hole 51h, the second lid portion 52 is arranged in the deformation direction of the leaf spring portion 60, as shown in FIG. Therefore, the amount of elastic deformation of the leaf spring section 60 is limited to within the gap size between the closing plate section 63 and the second lid section 52. According to the present embodiment, it is possible to suppress plastic deformation of the leaf spring portion 60 beyond the elastic region. Therefore, damage to the leaf spring part 60 can be suppressed when an excessive force is applied to the leaf spring part 60 due to the wiring 39 in the notch 45 being unaligned during assembly.
本実施の形態において、板バネ部60は、第1蓋部51から第1蓋部51の板面51aと平行に延びる第1弾性部61aと、第1弾性部61aに繋がり板面51aに対し複数の配線39側に傾斜する第2弾性部61bと、を有する。
In the present embodiment, the leaf spring section 60 includes a first elastic section 61a extending from the first lid section 51 in parallel to the plate surface 51a of the first lid section 51, and a first elastic section 61a connected to the first elastic section 61a with respect to the plate surface 51a. The second elastic portion 61b is inclined toward the plurality of wiring lines 39.
弾性部61は、複数の配線39から接触部62に対し力が付与されると、複数の配線39側に傾斜する第2弾性部61bが、第1弾性部61aよりも優先的に変形する。したがって、第1弾性部61aは、弾性部61において、比較的変形量が小さくなる。本実施の形態によれば、弾性部61の根元であって第1蓋部51との接続部分に、比較的変形量小さい第1弾性部61aが配置される。このため、第1蓋部51の孔部51hの内縁と弾性部61との境界部分に発生する応力集中を小さくすることができ、弾性部61が大きく変形しても根元部分に損傷を生じることを抑制できる。
In the elastic portion 61, when a force is applied to the contact portion 62 from the plurality of wires 39, the second elastic portion 61b that is inclined toward the plurality of wires 39 deforms preferentially than the first elastic portion 61a. Therefore, in the first elastic portion 61a, the amount of deformation in the elastic portion 61 is relatively small. According to the present embodiment, the first elastic portion 61a with a relatively small amount of deformation is arranged at the base of the elastic portion 61 and at the connection portion with the first lid portion 51. Therefore, stress concentration occurring at the boundary between the inner edge of the hole 51h of the first lid part 51 and the elastic part 61 can be reduced, and even if the elastic part 61 is significantly deformed, damage to the root part will not occur. can be suppressed.
