　圧縮機１０内には圧縮機モータ（図示せず）が備えられており、圧縮機モータはＵ相、Ｖ相及びＷ相の三相の巻線を有する三相モータである。圧縮機１０の容器１０ａの上部には、圧縮機１０の容器１０ａを貫通して２箇所にガラス端子１１ａ及びガラス端子１１ｂが設けられている。以下、ガラス端子１１ａ及びガラス端子１１ｂを総称してガラス端子１１ということがある。ガラス端子１１は、圧縮機モータの固定子に容器１０ａ外の制御基板２０から電源を供給するためのものである。 FIG. 2 is a perspective view of the upper part of the compressor provided in the outdoor unit of the air conditioner according to Embodiment 1 of the present invention.
A compressor motor (not shown) is provided in the compressor 10. The compressor motor is a three-phase motor having U-phase, V-phase and W-phase three-phase windings. In the upper part of the container 10a of the compressor 10, the glass terminal 11a and the glass terminal 11b are provided at two locations through the container 10a of the compressor 10. Hereinafter, the glass terminal 11 a and the glass terminal 11 b may be collectively referred to as the glass terminal 11. The glass terminal 11 is for supplying power to the stator of the compressor motor from the control board 20 outside the container 10a.
　ガラス端子１１ａは３本の導電ピン１２を備える。３本の導電ピン１２のそれぞれは、容器１０ａ内の圧縮機モータのＵ相、Ｖ相及びＷ相のそれぞれの巻線の一端部に接続される。このように、ガラス端子１１ａには、Ｕ相、Ｖ相及びＷ相の各１本ずつの計３本の導電ピン１２が一組として設けられている。また、ガラス端子１１ｂも同様に３本の導電ピン１３を備え、３本の導電ピン１３のそれぞれは、容器１０ａ内の圧縮機モータのＵ相、Ｖ相及びＷ相のそれぞれの巻線の一端部に接続される。このように、ガラス端子１１ｂには、Ｕ相、Ｖ相及びＷ相の各１本ずつの計３本の導電ピン１３が一組として設けられている。以上の構成により、圧縮機モータに電源が供給されるようになっている。 The glass terminal 11 a includes three conductive pins 12. Each of the three conductive pins 12 is connected to one end of each of the U-phase, V-phase and W-phase windings of the compressor motor in the container 10a. Thus, a total of three conductive pins 12 of one each of the U phase, the V phase and the W phase are provided as a set on the glass terminal 11a. Further, the glass terminal 11b is similarly provided with three conductive pins 13, and each of the three conductive pins 13 is one end of each of the U-phase, V-phase and W-phase windings of the compressor motor in the container 10a. Connected to the department. Thus, a total of three conductive pins 13 of one each of the U phase, the V phase and the W phase are provided as a set on the glass terminal 11 b. With the above configuration, power is supplied to the compressor motor.
　そして、ガラス端子１１ａの導電ピン１２は、円筒のピン形状を有している。ガラス端子１１ｂの導電ピン１３は、円筒のピンに端子接続板１３ａが取り付けられた構成を有している。 And the conductive pin 12 of the glass terminal 11a has a cylindrical pin shape. The conductive pin 13 of the glass terminal 11b has a configuration in which the terminal connection plate 13a is attached to a cylindrical pin.
　図３は、本発明の実施の形態１に係る空気調和機の室外機に備えられた圧縮機と制御基板との接続状態の説明図である。図４は、図３の圧縮機の拡大斜視図である。
　制御基板２０には、それぞれ３本のリード線で構成された、リード線群３１及びリード線群３２のそれぞれの一端部が接続されている。リード線群３１の他端部には端部コネクタとしてクラスターブロック１４が取り付けられ、クラスターブロック１４がガラス端子１１ａの導電ピン１２に着脱自在に接続されている。また、リード線群３２の各リード線それぞれの他端部には、端部コネクタとして旗型端子１５が取り付けられ、旗型端子１５がガラス端子１１ｂの導電ピン１３に着脱自在に接続されている。以上により、制御基板２０と圧縮機１０とが電気的に接続されている。なお、旗型端子１５は、図３及び図４では詳細に図示されていないが、端子接続板１３ａが挿入される被挿入部を有し、被挿入部に端子接続板１３ａが挿入されることで旗型端子１５と導電ピン１３とが接続される。 FIG. 3: is explanatory drawing of the connection state of the compressor and control board with which the outdoor unit of the air conditioner concerning Embodiment 1 of this invention was equipped. FIG. 4 is an enlarged perspective view of the compressor of FIG. 3;
The control board 20 is connected to one end of each of a lead wire group 31 and a lead wire group 32, each of which is constituted by three lead wires. A cluster block 14 is attached to the other end of the lead wire group 31 as an end connector, and the cluster block 14 is detachably connected to the conductive pin 12 of the glass terminal 11a. In addition, a flag type terminal 15 is attached as an end connector to the other end of each lead wire group 32, and the flag type terminal 15 is detachably connected to the conductive pin 13 of the glass terminal 11b. . Thus, the control board 20 and the compressor 10 are electrically connected. Although the flag type terminal 15 is not shown in detail in FIGS. 3 and 4, it has an inserted portion into which the terminal connection plate 13a is inserted, and the terminal connection plate 13a is inserted into the inserted portion. Thus, the flag type terminal 15 and the conductive pin 13 are connected.
　クラスターブロック１４は樹脂製である。旗型端子１５は金属製である。旗型端子１５には、図４に示すように端子スリーブ１６が装着されている。導電ピン１３と旗型端子１５との接触不良が発生した場合に生じる火花放電による火災の発生を防止するため、端子スリーブ１６は、難燃性の素材で構成されている。図４では、一つの旗型端子１５にのみ、端子スリーブ１６が装着された状態を図示しているが、全ての旗型端子１５に端子スリーブ１６が装着されている。 The cluster block 14 is made of resin. The flag type terminal 15 is made of metal. A terminal sleeve 16 is attached to the flag type terminal 15 as shown in FIG. In order to prevent the occurrence of fire due to spark discharge which occurs when contact failure between the conductive pin 13 and the flag type terminal 15 occurs, the terminal sleeve 16 is made of a flame-retardant material. Although FIG. 4 illustrates the state in which the terminal sleeve 16 is attached to only one flag-type terminal 15, the terminal sleeve 16 is attached to all the flag-type terminals 15.
　ところで、本実施の形態１の空気調和機の室外機は、制御基板２０に設けられた巻線切替部（図示せず）によって、圧縮機モータの結線をＹ結線とΔ結線とに切替可能な構成を有している。Ｙ結線は、圧縮機モータの回転数が低い場合に効率が良く、Δ結線は、圧縮機モータの回転数が高い場合に効率が良い結線構造である。巻線切替部は具体的にはリレーで構成されており、本実施の形態１の室外機は、このように運転条件に応じて圧縮機モータの結線を巻線切替部で切り替えることで、省エネルギー性の向上が可能なものである。なお、圧縮機モータの結線をＹ結線とΔ結線とに切り替える技術は公知の技術であり、公知の技術を用いて巻線切替部を構成すればよい。 By the way, the outdoor unit of the air conditioner according to the first embodiment can switch the connection of the compressor motor between Y connection and Δ connection by a winding switching unit (not shown) provided on the control board 20. It has a configuration. The Y connection is efficient when the rotational speed of the compressor motor is low, and the Δ connection is an efficient connection structure when the rotational speed of the compressor motor is high. Specifically, the winding switching unit is configured of a relay, and the outdoor unit according to the first embodiment thus saves energy by switching the connection of the compressor motor by the winding switching unit according to the operating conditions. It is possible to improve the sex. The technique for switching the connection of the compressor motor between the Y connection and the Δ connection is a known technique, and the winding switching unit may be configured using the known technique.
　結線方式の切り替えを行わないタイプの圧縮機では、圧縮機モータのＵ相、Ｖ相及びＷ相のそれぞれの巻線に繋がっている計３本の導電ピンが、１つのガラス端子にまとめられて配置された構成となる。しかしながら、本実施の形態１のように結線方式を切り替えるタイプの圧縮機では、圧縮機モータのＵ相、Ｖ相及びＷ相のそれぞれの巻線の両端部を、制御基板２０の巻線切替部に接続する必要がある。このため、計６つの導電ピンが必要となり、故に、上述したようにＵ相、Ｖ相及びＷ相に接続される３本の導電ピンを一組として備えたガラス端子を２つ、容器１０ａ上部に配置した構成となっている。 In the type of compressor that does not switch the connection method, a total of three conductive pins connected to the U-phase, V-phase and W-phase windings of the compressor motor are combined into one glass terminal. It will be arranged configuration. However, in the compressor of the type in which the wire connection method is switched as in the first embodiment, both end portions of each of the U-phase, V-phase and W-phase windings of the compressor motor Need to be connected. For this reason, a total of six conductive pins are required. Therefore, as described above, two glass terminals each including three conductive pins connected to the U phase, the V phase and the W phase as a set, the upper portion of the container 10a It is arranged in the
　リード線群３１の接続先は、回路構成上、ガラス端子１１ａと決まっている。リード線群３２の接続先もまた、回路構成上、ガラス端子１１ｂと決まっている。そして、リード線群３１の制御基板２０側は、巻線切替部を介してＵ相、Ｖ相及びＷ相のそれぞれに接続されており、リード線群３１の圧縮機１０側は、上述したようにクラスターブロック１４を用いてガラス端子１１ａに接続される。また、リード線群３２の制御基板２０側は、巻線切替部を介してＵ相、Ｖ相及びＷ相のそれぞれに接続されており、リード線群３２の圧縮機１０側は上述したように旗型端子１５を用いてガラス端子１１ｂに接続される。 The connection destination of the lead wire group 31 is determined to be the glass terminal 11a in view of the circuit configuration. The connection destination of the lead wire group 32 is also determined to be the glass terminal 11b in terms of the circuit configuration. The control substrate 20 side of the lead wire group 31 is connected to each of the U phase, V phase and W phase via the winding switching unit, and the compressor 10 side of the lead wire group 31 is as described above. The cluster block 14 is used to connect to the glass terminal 11a. Further, the control board 20 side of the lead wire group 32 is connected to each of the U phase, V phase and W phase via the winding switching unit, and the compressor 10 side of the lead wire group 32 is as described above. It is connected to the glass terminal 11 b using the flag type terminal 15.
　ここで、リード線群３１及びリード線群３２の長さが長すぎると、組み立て難い。このため、リード線群３１及びリード線群３２は、図３に示すように長手方向の途中で分割されている。そして、リード線群３１には、その分割部分に互いに着脱可能な一対の中継コネクタ３３が設けられ、一対の中継コネクタ３３で着脱自在に連結可能となっている。そして、一対の中継コネクタ３３の一方はオス型コネクタ３３ａで構成され、他方はメス型コネクタ３３ｂで構成されている。また、リード線群３２も同様に、長手方向の途中で分割され、分割部分に互いに着脱可能な一対の中継コネクタ３４が設けられ、一対の中継コネクタ３４で着脱自在に連結可能となっている。そして、一対の中継コネクタ３４の一方はオス型コネクタ３４ａで構成され、他方はメス型コネクタ３４ｂで構成されている。 Here, if the lengths of the lead wire group 31 and the lead wire group 32 are too long, it is difficult to assemble. For this reason, the lead wire group 31 and the lead wire group 32 are divided midway in the longitudinal direction as shown in FIG. The lead wire group 31 is provided with a pair of relay connectors 33 that can be attached to and detached from each other at the divided portions, and can be detachably connected by the pair of relay connectors 33. And one side of a pair of relay connectors 33 is constituted by male connector 33a, and the other is constituted by female connector 33b. Similarly, the lead wire group 32 is also divided midway in the longitudinal direction, and the divided portions are provided with a pair of relay connectors 34 that are removable from each other, and can be detachably connected by the pair of relay connectors 34. And one side of a pair of relay connectors 34 is constituted by male connector 34a, and the other is constituted by female connector 34b.
　そして、リード線群３１をガラス端子１１ｂに接続し、リード線群３２をガラス端子１１ａに接続するという誤配線が生じると、Ｙ結線とΔ結線と切り替えが正常に機能しなくなる。このため、本実施の形態１では、このような誤配線を防止する構成として以下の構成としている。なお、以下では、２つに分割されたリード線群３１のうち、制御基板２０側をリード線群３１ａ、圧縮機１０側をリード線群３１ｂという。また、同様に、リード線群３２のうち、制御基板２０側をリード線群３２ａ、圧縮機１０側をリード線群３２ｂという。 Then, if an incorrect wiring occurs such as connecting the lead wire group 31 to the glass terminal 11b and connecting the lead wire group 32 to the glass terminal 11a, the Y connection and the Δ connection do not function properly. Therefore, in the first embodiment, the following configuration is employed as a configuration for preventing such erroneous wiring. Hereinafter, among the lead wire groups 31 divided into two, the control substrate 20 side is referred to as a lead wire group 31a, and the compressor 10 side is referred to as a lead wire group 31b. Similarly, in the lead wire group 32, the control substrate 20 side is referred to as a lead wire group 32a, and the compressor 10 side is referred to as a lead wire group 32b.
　リード線群３１とリード線群３２とにおいて、制御基板２０側のリード線群同士を比較すると、リード線群３１ａの長さをリード線群３２ａの長さよりも長くしている。また、圧縮機１０側のリード線群同士を比較すると、リード線群３１ｂの長さをリード線群３２ｂの長さよりも短くしている。すなわち、一対の中継コネクタ３３及び一対の中継コネクタ３４を境としたリード線の長さを、リード線群毎に異なる構成としている。 In the lead wire group 31 and the lead wire group 32, when the lead wire groups on the control substrate 20 side are compared, the length of the lead wire group 31a is longer than the length of the lead wire group 32a. Moreover, when the lead wire groups on the compressor 10 side are compared with each other, the length of the lead wire group 31b is shorter than the length of the lead wire group 32b. That is, the lengths of the lead wires bordering the pair of relay connectors 33 and the pair of relay connectors 34 are configured to be different for each lead wire group.
　このように構成することで、誤配線を物理的に行えなくしている。すなわち、圧縮機１０側のリード線群３１ｂがガラス端子１１ａに接続され、リード線群３２ｂがガラス端子１１ｂに接続された状態にあるとする。また、一対の中継コネクタ３３及び一対の中継コネクタ３４での連結が成されていない状態にあるとする。ここで、ガラス端子１１ａとガラス端子１１ｂとでは導電ピン１２と導電ピン１３との形状が異なっている。このため、組立作業者が、圧縮機１０側のリード線群３１ｂ及びリード線群３２ｂをガラス端子へ接続する際には、クラスターブロック１４と旗型端子１５とをどちらのガラス端子に接続すればよいか、一瞥して一意に決定できる。つまり、図４に示すように、リード線群３１ｂのクラスターブロック１４はガラス端子１１ａへ接続され、リード線群３２ｂの旗型端子１５はガラス端子１１ｂへ接続される。 By configuring in this manner, erroneous wiring can not be physically performed. That is, it is assumed that the lead wire group 31b on the compressor 10 side is connected to the glass terminal 11a, and the lead wire group 32b is connected to the glass terminal 11b. Further, it is assumed that the connection by the pair of relay connectors 33 and the pair of relay connectors 34 is not performed. Here, the shapes of the conductive pin 12 and the conductive pin 13 are different between the glass terminal 11 a and the glass terminal 11 b. For this reason, when the assembly worker connects the lead wire group 31b and the lead wire group 32b on the compressor 10 side to the glass terminal, the cluster block 14 and the flag type terminal 15 should be connected to either glass terminal. At a glance, you can make a unique decision. That is, as shown in FIG. 4, the cluster block 14 of the lead wire group 31b is connected to the glass terminal 11a, and the flag type terminal 15 of the lead wire group 32b is connected to the glass terminal 11b.
　そして、この状態から制御基板２０側のリード線群３１ａ及びリード線群３２ａを、圧縮機１０側のリード線群３１ｂ及びリード線群３２ｂに、一対の中継コネクタ部分で連結する場合について考える。この場合、リード線群３１ａのオス型コネクタ３３ａは、リード線群３２ｂのメス型コネクタ３４ｂに連結可能である。しかし、リード線群３２ａのオス型コネクタ３４ａは、リード線群３１ａのメス型コネクタ３３ｂまで長さが届かず、連結できない。このため、誤配線を防止することができる。 From this state, a case will be considered in which the lead wire group 31a and the lead wire group 32a on the control substrate 20 side are connected to the lead wire group 31b and the lead wire group 32b on the compressor 10 side by a pair of relay connectors. In this case, the male connector 33a of the lead wire group 31a can be connected to the female connector 34b of the lead wire group 32b. However, the male connector 34a of the lead wire group 32a can not be connected because the length does not reach the female connector 33b of the lead wire group 31a. Thus, erroneous wiring can be prevented.
　以上説明したように、本実施の形態１によれば、リード線群が長手方向の途中で分割されて、その分割部分で着脱自在に連結されており、制御基板２０から分割部分までの長さと、分割部分から端部コネクタまでの長さとが、リード線群毎に異なる構成とした。このため、誤配線を物理的に防止することができる。 As described above, according to the first embodiment, the lead wire group is divided midway in the longitudinal direction and releasably connected at the divided portion, and the length from the control substrate 20 to the divided portion The length from the divided portion to the end connector is different for each lead wire group. Therefore, erroneous wiring can be physically prevented.
　また、リード線群毎に、端部コネクタをクラスターブロック１４と旗型端子１５とで異ならせている。これに伴って、ガラス端子１１ａとガラス端子１１ｂとでは導電ピンの形状が異なっている。このため、クラスターブロック１４と旗型端子１５とを、誤ったガラス端子側に接続することを防止できる。また、クラスターブロック１４と旗型端子１５とを、どちらのガラス端子１１に接続すればよいか、一瞥して一意に決定でき、組立時間の短縮化にも効果的である。 Moreover, the end connector is made to differ by the cluster block 14 and the flag type | mold terminal 15 for every lead wire group. Along with this, the shape of the conductive pin is different between the glass terminal 11a and the glass terminal 11b. For this reason, it can prevent connecting the cluster block 14 and the flag type | mold terminal 15 to the wrong glass terminal side. In addition, it is possible to uniquely determine, at a glance, which glass terminal 11 should be connected to the cluster block 14 and the flag type terminal 15, which is also effective in shortening the assembly time.
　また、端子スリーブ１６は、上述したように火災の発生を防止するために用いられるが、ここでは、旗型端子１５の導電ピン１３への取付け及び取外しの作業性を向上するための役割も有する。すなわち、端子スリーブ１６の形状及び色の一方又は両方を各旗型端子１５毎に変えることにより、旗型端子１５を導電ピン１３に接続する際の誤配線防止を行うことが可能になる。 Also, although the terminal sleeve 16 is used to prevent the occurrence of a fire as described above, it also has a role to improve the workability of attaching and detaching the flag type terminal 15 to the conductive pin 13 here. . That is, by changing one or both of the shape and the color of the terminal sleeve 16 for each flag terminal 15, it is possible to prevent erroneous wiring when connecting the flag terminal 15 to the conductive pin 13.
　なお、本発明の空気調和機の室外機は、上記各図に示した構造に限定されるものではなく、本発明の要旨を逸脱しない範囲で種々の変形が可能である。例えば、リード線の色又は一対の中継コネクタの色を、リード線群３１とリード線群３２とで異ならせてもよい。以下、リード線の色をリード線群毎に異ならせた構成について、図５を用いて説明する。 In addition, the outdoor unit of the air conditioner of this invention is not limited to the structure shown to said each figure, A various deformation | transformation is possible in the range which does not deviate from the summary of this invention. For example, the color of the lead wire or the color of the pair of relay connectors may be made different between the lead wire group 31 and the lead wire group 32. Hereinafter, a configuration in which the color of the lead wire is made different for each lead wire group will be described with reference to FIG.
　図５は、本発明の実施の形態１に係る空気調和機の室外機の変形例を示す図である。図５においてリード線の太さ及び線種の違いは、リード線の色の違いを示している。
　この変形例では、リード線群毎に各リード線の色の組み合わせを異ならせている。すなわち、リード線群３１は、例えば、黒いリード線（太い実線）３１Ａ、青いリード線（細い実線）３１Ｂ、赤いリード線（太い点線）３１Ｃの組み合わせで構成される。一方、リード線群３２は、黒いリード線（太い実線）３２Ａ、白いリード線（細い一点鎖線）３２Ｂ、赤いリード線（太い点線）３２Ｃの組み合わせで構成される。 FIG. 5 is a view showing a modified example of the outdoor unit of the air conditioner according to Embodiment 1 of the present invention. The difference in lead wire thickness and line type in FIG. 5 indicates the difference in lead wire color.
In this modification, the combination of the colors of the lead wires is made different for each lead wire group. That is, the lead wire group 31 includes, for example, a combination of a black lead wire (thick solid line) 31A, a blue lead wire (thin solid line) 31B, and a red lead wire (thick dotted line) 31C. On the other hand, the lead wire group 32 is configured by a combination of black lead wires (thick solid line) 32A, white lead wires (thin dashed dotted line) 32B, and red lead wires (thick dotted line) 32C.
　このようにリード線群毎にリード線の色の組み合わせを異ならせることで、より視覚的に接続先を見分けることができ、誤配線を防止できる。なお、ここでは、リード線群毎に各リード線の色の組み合わせを異ならせているが、リード線群３１の各リード線を全て黒、リード線群３２の各リード線を全て赤、というようにリード線群毎に各リード線の色をまとめて異ならせるようにしてもよい。 By thus changing the combination of lead wire colors for each lead wire group, it is possible to visually distinguish the connection destination and to prevent erroneous wiring. Here, the color combinations of the lead wires are different for each lead wire group, but all lead wires of the lead wire group 31 are black, and all lead wires of the lead wire group 32 are red and so on. Alternatively, the color of each lead may be collectively different for each lead group.
実施の形態２．
　実施の形態２は、実施の形態１とは異なる誤配線の防止構造を一対の中継コネクタ部分に設けたものである。以下、実施の形態２が実施の形態１と異なる点を中心に説明し、本実施の形態２で説明されていない構成は実施の形態１と同様である。 Second Embodiment
In the second embodiment, an erroneous wiring preventing structure different from the first embodiment is provided in a pair of relay connector portions. In the following, the second embodiment will be described focusing on differences from the first embodiment, and the configuration not described in the second embodiment is the same as the first embodiment.
　図６は、本発明の実施の形態２に係る空気調和機の室外機に備えられた圧縮機と制御基板との接続状態の説明図である。
　上記実施の形態１では、一対の中継コネクタ３３及び一対の中継コネクタ３４を構成するオス型コネクタとメス型コネクタとの振り分けを、リード線群３１とリード線群３２とで同じとしていた。これに対し、実施の形態２では、リード線群３１とリード線群３２とで、オス型コネクタとメス型コネクタとの振り分けを異ならせている。すなわち、図６に示すようにリード線群３１では、制御基板２０側をオス型、圧縮機１０側をメス型としているのに対し、リード線群３２では、制御基板２０側をメス型、圧縮機１０側をオス型としている。 FIG. 6 is an explanatory view of a connection state between a compressor and a control board provided in the outdoor unit of the air conditioner according to Embodiment 2 of the present invention.
In the first embodiment, the distribution of the male connector and the female connector constituting the pair of relay connectors 33 and the pair of relay connectors 34 is made the same for the lead wire group 31 and the lead wire group 32. On the other hand, in the second embodiment, distribution of male connectors and female connectors is made different between the lead wire group 31 and the lead wire group 32. That is, as shown in FIG. 6, in the lead wire group 31, the control substrate 20 side is a male type and the compressor 10 side is a female type, while in the lead wire group 32, the control substrate 20 side is a female type The machine 10 side is male type.
　この構成により、例えばリード線群３１ａをガラス端子１１ｂ側に接続されたリード線群３２ｂに接続するといった誤配線は、コネクタが共にオス型となるため起こりえない。また、中継コネクタ部分のオス型とメス型とを確認することで、リード線群３１ａ及びリード線群３２ａを、リード線群３１ｂ及びリード線群３２ｂのどちらに接続したらよいか、容易に見分けることができる。その結果、組立時間の短縮を図ることができ、組立性能を向上できる。 With this configuration, erroneous wiring such as connecting the lead wire group 31a to the lead wire group 32b connected to the glass terminal 11b can not occur because the connectors are both male. In addition, it is easy to distinguish between the lead wire group 31a and the lead wire group 32a which one of the lead wire group 31b and the lead wire group 32b should be connected by confirming the male type and the female type of the relay connector portion. Can. As a result, the assembly time can be shortened, and the assembly performance can be improved.
　以上説明したように、本実施の形態２によれば、リード線群３１とリード線群３２とで一対の中継コネクタ部分におけるオス型とメス型の振り分けを異ならせるようにした。これにより、一対の中継コネクタ部分における誤った接続を物理的に不可能とすることができ、誤配線を防止できる。また、接続先を視覚的に容易に見分けることができ、組立性能を向上できる。 As described above, according to the second embodiment, the distribution of the male type and the female type in the pair of relay connector portions is made different between the lead wire group 31 and the lead wire group 32. Thereby, the incorrect connection in a pair of relay connector part can be physically made impossible, and a miswire can be prevented. Also, the connection destination can be visually identified easily, and the assembly performance can be improved.
　なお、図６では、実施の形態１の技術を備え、一対の中継コネクタ３３及び一対の中継コネクタ３４を境としたリード線群の長さをリード線群毎に異なる構成としている。しかし、実施の形態２は、あくまでも中継コネクタにおけるオス型とメス型との振り分けをリード線群３１とリード線群３２とで異ならせることを特徴としたものであり、実施の形態１の技術は備えていなくてもよい。つまり、制御基板２０から分割部分までの長さと、分割部分から端部コネクタまでの長さを、リード線群同士で同じとしてもよい。この場合でも、実施の形態２の技術を備えることで、誤配線を防止することができる。また、実施の形態１の変形例で説明した、リード線群毎に３本のリード線の色の組み合わせを異ならせたり、リード線群毎に３本のリード線の色をまとめて異ならせたりする構成を実施の形態２に適用してもよい。 6 includes the technology of the first embodiment, and the length of the lead wire group bordering the pair of relay connectors 33 and the pair of relay connectors 34 is configured to be different for each lead wire group. However, the second embodiment is characterized in that the distribution of the male type and the female type in the relay connector is completely different between the lead wire group 31 and the lead wire group 32, and the technique of the first embodiment is It is not necessary to have it. That is, the lengths from the control board 20 to the divided portion and the lengths from the divided portion to the end connector may be the same between the lead wire groups.
