収容室１０ａは、組み付けられた室内の電気接続具２０から作業用開口１０ｂまでの空間（以下、「第１収容室」という。）１０ａ１と、その室内の電気接続具２０から底壁１２までの空間（以下、「第２収容室」という。）１０ａ２と、に大別される（図２）。この収容室１０ａにおいては、第１コネクタ付き電線群が第１収容室１０ａ１に収容され、この第１コネクタ付き電線群の第１開口側電線Ｗｏ１と第２開口側電線Ｗｏ２が第１収容室１０ａ１から外に引き出される。また、この収容室１０ａにおいては、それぞれの第２コネクタ付き電線群における第１底部側コネクタ５２Ａと第２底部側コネクタ５２Ｂが第２収容室１０ａ２に収容され、それぞれの第２コネクタ付き電線群における第１底部側電線Ｗｂ１と第２底部側電線Ｗｂ２が第２収容室１０ａ２から第１収容室１０ａ１に引き回されて当該第１収容室１０ａ１から外に引き出される。 The storage chamber 10a includes a space 10a1 from the assembled electrical connector 20 to the working opening 10b (hereinafter referred to as "first storage chamber"), and a space 10a1 in the chamber from the electrical connector 20 to the bottom wall 12. The space (hereinafter referred to as "second storage room") 10a2 is roughly divided into (Fig. 2). In this accommodation chamber 10a, the first connector-equipped wire group is accommodated in the first accommodation chamber 10a1 , and the first opening-side electric wire Wo1 and the second opening-side electric wire Wo2 of the first connector-equipped wire group are accommodated in the first accommodation chamber 10a1. 10a 1 is pulled out. In addition, in this storage chamber 10a, the first bottom side connector 52A and the second bottom side connector 52B in each second connector-equipped wire group are accommodated in the second storage chamber 10a2 , and each second connector-equipped wire group , the first bottom-side electric wire Wb1 and the second bottom-side electric wire Wb2 are routed from the second storage chamber 10a2 to the first storage chamber 10a1 and pulled out from the first storage chamber 10a1 .

それぞれの第２コネクタ付き電線群は、収容室１０ａに収容される前の電気接続具２０に組み付けておく。しかしながら、それぞれの第２コネクタ付き電線群の第１底部側コネクタ５２Ａは、そのハウジング部が各々同じ形状に形成されている。そして、それぞれの第２相手方コネクタ群の第１相手方底部側コネクタ２７ａは、そのハウジング部が各々同じ形状に形成されている。このため、このワイヤハーネスＷＨにおいては、それぞれの第１底部側コネクタ５２Ａを何処の第１相手方底部側コネクタ２７ａに嵌合接続させればよいのか簡単に見分けることが難しい。よって、このワイヤハーネスＷＨにおいては、第１底部側コネクタ５２Ａと第１相手方底部側コネクタ２７ａとの間での誤接続を予め抑止させることが望ましい。 Each second connector-equipped wire group is assembled to the electrical connector 20 before being housed in the housing chamber 10a. However, the housing portions of the first bottom side connectors 52A of the respective groups of wires with second connectors are formed in the same shape. The housing portions of the first mating bottom side connectors 27a of the respective second mating connector groups are formed in the same shape. Therefore, in the wire harness WH, it is difficult to easily distinguish which first mating bottom-side connector 27a each first bottom-side connector 52A should be fit-connected. Therefore, in this wire harness WH, it is desirable to previously prevent erroneous connection between the first bottom side connector 52A and the first mating bottom side connector 27a.

また、それぞれの第２コネクタ付き電線群の第２底部側コネクタ５２Ｂは、そのハウジング部が各々同じ形状に形成されている。そして、それぞれの第２相手方コネクタ群の第２相手方底部側コネクタ２７ｂは、そのハウジング部が各々同じ形状に形成されている。このため、このワイヤハーネスＷＨにおいては、それぞれの第２底部側コネクタ５２Ｂを何処の第２相手方底部側コネクタ２７ｂに嵌合接続させればよいのか簡単に見分けることが難しい。よって、このワイヤハーネスＷＨにおいては、第２底部側コネクタ５２Ｂと第２相手方底部側コネクタ２７ｂとの間での誤接続についても予め抑止させることが望ましい。 Further, the housing portions of the second bottom side connectors 52B of the respective groups of electric wires with second connectors are formed in the same shape. The housing portions of the second mating bottom side connectors 27b of the respective second mating connector groups are formed in the same shape. Therefore, in the wire harness WH, it is difficult to easily distinguish which second mating bottom side connector 27b each second bottom side connector 52B should be fit-connected. Therefore, in the wire harness WH, it is desirable to prevent erroneous connection between the second bottom side connector 52B and the second mating bottom side connector 27b in advance.

更に、ここでは、第１底部側コネクタ５２Ａと第２底部側コネクタ５２Ｂのそれぞれのハウジング部が見分けの付き難い類似形状に形成されている。そして、ここでは、第１相手方底部側コネクタ２７ａと第２相手方底部側コネクタ２７ｂのそれぞれのハウジング部が見分けの付き難い類似形状に形成されている。このため、このワイヤハーネスＷＨにおいては、第１底部側コネクタ５２Ａと第２相手方底部側コネクタ２７ｂとの間での誤接続や第２底部側コネクタ５２Ｂと第１相手方底部側コネクタ２７ａとの間での誤接続についても予め抑止させることが望ましい。 Further, here, the respective housing portions of the first bottom-side connector 52A and the second bottom-side connector 52B are formed in similar shapes that are difficult to distinguish. Here, the respective housing portions of the first mating bottom side connector 27a and the second mating bottom side connector 27b are formed in similar shapes that are difficult to distinguish. For this reason, in the wire harness WH, an erroneous connection between the first bottom-side connector 52A and the second mating bottom-side connector 27b, or an erroneous connection between the second bottom-side connector 52B and the first mating bottom-side connector 27a may occur. It is desirable to prevent erroneous connection in advance.

そこで、このワイヤハーネスＷＨにおいては、それぞれの第２コネクタ付き電線群と電気接続具２０の誤接続を抑止するべく、次のような構成を採っている。 Therefore, the wire harness WH adopts the following configuration in order to prevent erroneous connection between the electric wire group with the second connector and the electrical connector 20 .

第２コネクタ付き電線群は、自身のそれぞれの電線（ここでは一組の第１底部側電線Ｗｂ１と第２底部側電線Ｗｂ２）を一纏めに束ね、かつ、電気接続具２０の被固定部２７ｄに固定させる電線保持具５６を備える（図２及び図５から図８）。この電線保持具５６は、第２コネクタ付き電線群毎に設ける。 The second connector-equipped electric wire group bundles its respective electric wires (here, a pair of first bottom-side electric wire Wb1 and second bottom-side electric wire Wb2) together and attaches to the fixed portion 27d of the electrical connector 20. A fixed wire holder 56 is provided (FIGS. 2 and 5-8). This wire holder 56 is provided for each second connector-equipped wire group.

Therefore, in the wire harness WH, situations such as the wires (the first bottom-side wires Wb1 and the second bottom-side wires Wb2) of the plurality of second connector-equipped wire groups overlapping each other in the housing chamber 10a are prevented. can be suppressed. Therefore, the wire harness WH can improve the space efficiency of the storage chamber 10a, so that, for example, the size of the housing 10 can be reduced.

更に、このワイヤハーネスＷＨにおいては、そのような複数の第２コネクタ付き電線群同士のそれぞれの電線（第１底部側電線Ｗｂ１、第２底部側電線Ｗｂ２）の重なり合いを抑制することで、その電線同士のノイズ干渉を低減させることができる。そして、このワイヤハーネスＷＨにおいては、第２コネクタ付き電線群が同一回路における正負何れか一方の第１底部側電線Ｗｂ１と正負何れか他方の第２底部側電線Ｗｂ２とを備えており、この第１底部側電線Ｗｂ１と第２底部側電線Ｗｂ２を電線保持具５６で一纏めに束ねている。このため、その第２コネクタ付き電線群においては、第１底部側電線Ｗｂ１と第２底部側電線Ｗｂ２のそれぞれのノイズを相殺することができる。このように、このワイヤハーネスＷＨは、第２コネクタ付き電線群毎にそれぞれの電線（第１底部側電線Ｗｂ１、第２底部側電線Ｗｂ２）を電線保持具５６で束ねた上で、その経路を規制することによって、ノイズの低減効果を高めることができる。 Furthermore, in the wire harness WH, by suppressing the overlapping of the electric wires (the first bottom-side electric wires Wb1 and the second bottom-side electric wires Wb2) of such a plurality of second connector-equipped electric wire groups, the electric wires noise interference between them can be reduced. In the wire harness WH, the second connector-equipped wire group includes a positive or negative first bottom side wire Wb1 and a positive or negative second bottom side wire Wb2 in the same circuit. The first bottom-side electric wire Wb1 and the second bottom-side electric wire Wb2 are bundled together by the electric wire holder 56 . Therefore, in the second connector-equipped electric wire group, the noises of the first bottom-side electric wires Wb1 and the second bottom-side electric wires Wb2 can be canceled. In this manner, the wire harness WH bundles the wires (the first bottom-side wires Wb1 and the second bottom-side wires Wb2) for each second connector-equipped wire group with the wire holder 56, and then routes the wires. By restricting, the noise reduction effect can be enhanced.
