　＜実施例の作用及び効果＞
　次に、本実施例の作用を説明する。電源分配装置Ｄを組み付ける際には、予め、入力側コネクタ２０に入力側端子金具１４と接続金具１５を取り付けておく。また、各分岐用コネクタ４０には、出力側端子金具５８とバスバー４６を取り付けておく。この状態からコネクタ２０，４０同士を連結するが、連結の手順は２通りある。 <Operation and Effect of Example>
Next, the operation of this embodiment will be described. When the power distribution device D is assembled, the input side terminal fitting 14 and the connection fitting 15 are attached to the input side connector 20 in advance. Further, an output side terminal fitting 58 and a bus bar 46 are attached to each branch connector 40. The connectors 20 and 40 are connected from this state, and there are two connection procedures.
　１つ目の手順では、まず、複数の分岐用コネクタ４０同士を連結して分電モジュールＭを構成する。連結の際には、一方のハウジング４１と他方のハウジング４１を左右に対向させて接近させ、左側の分岐用コネクタ４０の突起状保持部４５を、右側のバスバー収容室４２内に挿入する。すると、突起状保持部４５の上面に重ねられている第２接続部４９が、右側の分岐用コネクタ４０の第１接続部４７を弾性的に押し上げながら第１接続部４７の下に潜り込む。そして、第１接続部４７の弾性復元力により、第１接続部４７の下端部と第２接続部４９の上面がバスバー収容室４２内で弾性的に接触し、バスバー４６同士が導通可能に接続される。 In the first procedure, first, the power distribution module M is configured by connecting a plurality of branch connectors 40 together. At the time of connection, the one housing 41 and the other housing 41 are made to approach each other in the left-right direction, and the protruding holding portion 45 of the left branch connector 40 is inserted into the right bus bar housing chamber 42. Then, the second connection part 49 superimposed on the upper surface of the protrusion-like holding part 45 enters under the first connection part 47 while elastically pushing up the first connection part 47 of the right branching connector 40. Then, due to the elastic restoring force of the first connecting portion 47, the lower end portion of the first connecting portion 47 and the upper surface of the second connecting portion 49 are elastically contacted in the bus bar accommodating chamber 42, and the bus bars 46 are connected to be conductive. Is done.
　また、２つの分岐用コネクタ４０のハウジング４１同士が左右に重なり合うと、右側の分岐用コネクタ４０の上部弾性連結片６８が、左側の分岐用コネクタ４０のハウジング４１を前後に挟みながら上部連結突起６３に係止するとともに、右側の分岐用コネクタ４０の下部弾性連結片６９が、左側の分岐用コネクタ４０の連結突部６５を前後に挟みながら下部連結突起６６に係止する。これにより、左右に隣り合う２つの分岐用コネクタ４０が、左右方向及び前後方向への相対変位を規制される。 Further, when the housings 41 of the two branch connectors 40 are overlapped on the left and right, the upper elastic connection piece 68 of the right branch connector 40 causes the upper connection protrusion 63 to sandwich the housing 41 of the left branch connector 40 in the front-rear direction. The lower elastic connecting piece 69 of the right branching connector 40 is locked to the lower connecting projection 66 while sandwiching the connecting projection 65 of the left branching connector 40 in the front-rear direction. As a result, the two branch connectors 40 adjacent to the left and right are restricted from relative displacement in the left-right direction and the front-rear direction.
　また、上部弾性連結片６８が、上部規制面６４に対して当接又は接近して対向するとともに、下部弾性連結片６９が、下部規制面６７に対して当接又は接近して対向するので、左右に隣り合う２つの分岐用コネクタ４０は、上下方向への相対変位を規制される。以上により、左右に隣り合う２つの分岐用コネクタ４０が、確実に連結される。そして、上記の連結作業を順次行うことにより、複数の分岐用コネクタ４０が左右に一列に並んだ状態で連結され、分電モジュールＭが構成される。分でモジュールの組み立てが完了すると、全ての分岐用コネクタ４０のバスバー４６同士が導通可能に接続される。 Further, the upper elastic coupling piece 68 is opposed to or approaches the upper regulating surface 64 and the lower elastic coupling piece 69 is opposed to or approaches the lower regulating surface 67. Two branch connectors 40 adjacent to the left and right are restricted in relative displacement in the vertical direction. As described above, the two branch connectors 40 adjacent to the left and right are reliably connected. Then, by sequentially performing the above connecting operation, the plurality of branch connectors 40 are connected in a line in the left and right, and the power distribution module M is configured. When the assembly of the modules is completed in minutes, the bus bars 46 of all the branch connectors 40 are connected so as to be conductive.
　分電モジュールＭの組み立てが完了したら、最も左側に位置する分岐用コネクタ４０に、入力側コネクタ２０を組み付ける。この組付けに際しては、入力側コネクタ２０のホルダ２１と分岐用コネクタ４０のハウジング４１を左右に対向させて接近させ、入力側コネクタ２０の突起状受け部２９を、分岐用コネクタ４０のバスバー収容室４２内に挿入する。すると、突起状受け部２９の上面に重ねられているバスバー用接続部１８が、分岐用コネクタ４０の第１接続部４７を弾性的に押し上げながら第１接続部４７の下に潜り込む。 When the assembly of the power distribution module M is completed, the input side connector 20 is assembled to the branch connector 40 located on the leftmost side. At the time of this assembly, the holder 21 of the input connector 20 and the housing 41 of the branch connector 40 are made to face each other in the left-right direction, and the protruding receiving portion 29 of the input connector 20 is placed in the bus bar housing chamber of the branch connector 40. 42 is inserted. Then, the bus bar connecting portion 18 superimposed on the upper surface of the protruding receiving portion 29 sinks under the first connecting portion 47 while elastically pushing up the first connecting portion 47 of the branching connector 40.
　そして、第１接続部４７の弾性復元力により、第１接続部４７の下端部とバスバー用接続部１８の上面がバスバー収容室４２内で弾性的に接触し、入力側コネクタ２０の接続金具１５と最も左側の分岐用コネクタ４０のバスバー４６とが導通可能に接続される。これにより、入力側コネクタ２０（入力側導電路１０）と、分電モジュールＭを構成する全ての分岐用コネクタ４０のバスバー４６とが導通可能に接続される。 Then, due to the elastic restoring force of the first connecting portion 47, the lower end portion of the first connecting portion 47 and the upper surface of the bus bar connecting portion 18 are elastically contacted in the bus bar accommodating chamber 42, and the connection fitting 15 of the input side connector 20. And the bus bar 46 of the leftmost branching connector 40 are connected so as to be conductive. Thereby, the input side connector 20 (input side conductive path 10) and the bus bar 46 of all the branch connectors 40 which comprise the electricity distribution module M are connected so that conduction | electrical_connection is possible.
　また、入力側コネクタ２０のホルダ２１と分岐用コネクタ４０のハウジング４１が左右に重なり合うと、分岐用コネクタ４０の上部弾性連結片６８が、入力側コネクタ２０のホルダ２１を前後に挟みながら上部受け突起２３に係止するとともに、分岐用コネクタ４０の下部弾性連結片６９が、入力側コネクタ２０の嵌合突部２５を前後に挟みながら下部受け突起２６に係止する。これにより、左右に隣り合う入力側コネクタ２０と分岐用コネクタ４０とが、左右方向及び前後方向への相対変位を規制される。 When the holder 21 of the input connector 20 and the housing 41 of the branch connector 40 are overlapped on the left and right, the upper elastic connecting piece 68 of the branch connector 40 holds the holder 21 of the input connector 20 back and forth while holding the upper receiving projection. 23, and the lower elastic coupling piece 69 of the branching connector 40 is locked to the lower receiving projection 26 while sandwiching the fitting projection 25 of the input side connector 20 in the front-rear direction. Thereby, the input side connector 20 and the branch connector 40 adjacent to the left and right are restricted from relative displacement in the left and right direction and the front and rear direction.
　また、分岐用コネクタ４０の上部弾性連結片６８が、入力側コネクタ２０の上部受け面２４に対して当接又は接近して対向するとともに、下部弾性連結片６９が、下部受け面２７に対して当接又は接近して対向するので、左右に隣り合う入力側コネクタ２０と分岐用コネクタ４０は、上下方向への相対変位を規制される。以上により、左右に隣り合う入力側コネクタ２０と分岐用コネクタ４０が確実に連結され、入力側コネクタ２０と分電モジュールＭが一体化される。 Further, the upper elastic coupling piece 68 of the branching connector 40 is opposed to or approaches the upper receiving surface 24 of the input side connector 20, and the lower elastic coupling piece 69 is opposed to the lower receiving surface 27. Since they abut or face each other close to each other, the input side connector 20 and the branching connector 40 adjacent to the left and right are restricted from relative displacement in the vertical direction. As described above, the input side connector 20 and the branch connector 40 adjacent to each other on the left and right are securely connected, and the input side connector 20 and the power distribution module M are integrated.
　この後、各電子部品収容室４４に、夫々、ヒューズ６０を取り付ける。取り付ける過程では、ヒューズ６０の左側に位置する入力側コネクタ２０又は分岐用コネクタ４０に形成されている弾性抜止片３０，７０が、左方へ弾性撓みする。そして、ヒューズ６０が電子部品収容室４４内に収容されると、弾性抜止片３０，７０が弾性復帰してヒューズ本体６１の上面左側縁部に対して上から係止する。この係止作用により、ヒューズ６０は、電子部品収容室４４内に収容された状態に保持される。 Thereafter, a fuse 60 is attached to each electronic component storage chamber 44. In the attaching process, the elastic retaining pieces 30, 70 formed on the input side connector 20 or the branch connector 40 located on the left side of the fuse 60 are elastically bent to the left. When the fuse 60 is housed in the electronic component housing chamber 44, the elastic retaining pieces 30 and 70 are elastically restored and locked to the upper left edge of the fuse body 61 from above. Due to this locking action, the fuse 60 is held in a state of being housed in the electronic component housing chamber 44.
　尚、ヒューズ６０を取り外す際には、手作業で弾性抜止片３０，７０を左方へ弾性撓みさせ、その状態でヒューズ６０を上方へ引き抜けばよい。ヒューズ６０を取り付けると、各分岐用コネクタ４０においてはバスバー４６と出力側端子金具５８（出力側導電路５５）とが導通可能に接続される。したがって、入力側導電路１０と複数の出力側導電路５５とが導通可能に接続される。これにより、バッテリＢの電力が各負荷Ｌへ分配されて供給される。 In addition, when removing the fuse 60, the elastic retaining pieces 30, 70 may be elastically bent to the left by hand, and the fuse 60 may be pulled upward in this state. When the fuse 60 is attached, in each branch connector 40, the bus bar 46 and the output side terminal fitting 58 (output side conductive path 55) are connected in a conductive manner. Therefore, the input side conductive path 10 and the plurality of output side conductive paths 55 are connected so as to be conductive. Thereby, the electric power of the battery B is distributed and supplied to each load L.
　コネクタ２０，４０同士を連結する２つ目の手順は、まず、入力側コネクタ２０のホルダ２１といずれか１つの分岐用コネクタ４０のハウジング４１を連結する。この連結作業は、上記と同様の要領で行うことができる。入力側コネクタ２０と分岐用コネクタ４０を連結すると、入力側コネクタ２０の接続金具１５（入力側導電路１０）と分岐用コネクタ４０のバスバー４６とが接続される。 The second procedure for connecting the connectors 20 and 40 is to first connect the holder 21 of the input-side connector 20 and the housing 41 of any one branching connector 40. This connecting operation can be performed in the same manner as described above. When the input side connector 20 and the branch connector 40 are connected, the connection fitting 15 (input side conductive path 10) of the input side connector 20 and the bus bar 46 of the branch connector 40 are connected.
　この後、入力側コネクタ２０に連結した分岐用コネクタ４０に対し、その右側から別の分岐用コネクタ４０を連結する。このときの連結も、上述と同様の要領で行うことができる。分岐コネクタ同士を連結すると、バスバー４６同士が接続される。同様にして、全ての分岐用コネクタ４０を、順次に連結する。そして、全ての分岐用コネクタ４０が連結されたら、分電モジュールＭの組み立てと、分電モジュールＭと入力側コネクタ２０の連結とが同時に完了する。 Thereafter, another branch connector 40 is connected to the branch connector 40 connected to the input side connector 20 from the right side. The connection at this time can also be performed in the same manner as described above. When the branch connectors are connected, the bus bars 46 are connected. Similarly, all the branch connectors 40 are sequentially connected. When all the branch connectors 40 are connected, the assembly of the distribution module M and the connection of the distribution module M and the input side connector 20 are completed at the same time.
　上述のように、本実施例の電源分配装置Ｄは、電力を複数の負荷Ｌへ供給するための装置であって、バッテリＢに接続される入力側導電路１０と、複数の分岐用コネクタ４０と、分岐用コネクタ４０を構成するハウジング４１と、ハウジング４１に取り付けられるとともに複数の負荷Ｌに接続される複数の出力側導電路５５とを備える。ハウジング４１には、バスバー４６が取り付けられている。バスバー４６には、接続金具１５を介して入力側導電路１０と接続可能な第１接続部４７と、第１接続部４７に接続可能な第２接続部４９とが形成されている。 As described above, the power distribution device D of this embodiment is a device for supplying power to the plurality of loads L, and includes the input side conductive path 10 connected to the battery B and the plurality of branch connectors 40. And a housing 41 constituting the branching connector 40 and a plurality of output-side conductive paths 55 attached to the housing 41 and connected to the plurality of loads L. A bus bar 46 is attached to the housing 41. The bus bar 46 is formed with a first connection portion 47 that can be connected to the input-side conductive path 10 via the connection fitting 15 and a second connection portion 49 that can be connected to the first connection portion 47.
　また、分岐用コネクタ４０にはヒューズ６０が着脱可能に設けられている。ヒューズ６０をハウジング４１に取り付けた状態では、出力側導電路５５とバスバー４６とが導通可能に接続される。ヒューズ６０をハウジング４１から取り外した状態では、出力側導電路５５とバスバー４６との導通が遮断される。かかる構成の電源分配装置Ｄを用いれば、入力側導電路１０に接続する分岐用コネクタ４０の数が、負荷Ｌの数に応じた必要最少数で済むので、小型化が可能である。 In addition, the branch connector 40 is provided with a fuse 60 in a detachable manner. In a state where the fuse 60 is attached to the housing 41, the output side conductive path 55 and the bus bar 46 are connected so as to be conductive. In a state where the fuse 60 is removed from the housing 41, the conduction between the output side conductive path 55 and the bus bar 46 is interrupted. If the power distribution device D having such a configuration is used, the number of branch connectors 40 connected to the input-side conductive path 10 can be reduced to the minimum necessary according to the number of loads L, and thus the size can be reduced.
　また、ハウジング４１には、他のハウジング４１に係止することでハウジング４１と他のハウジング４１とを連結状態に保持する連結部として、上部弾性連結片６８、下部弾性連結片６９、上部連結突起６３及び下部連結突起６６が形成されている。この構成によれば、複数のハウジング４１を連結した状態に保持することができるので、バスバー４６同士の接続状態が安定する。また、ハウジング４１と他のハウジング４１を連結した状態では、第１接続部４７と第２接続部４９との接続部分がハウジング４１内（バスバー収容室４２内）に収容されている。したがって、バスバー４６同士の接続部分を、異物の干渉等から保護することができる。 Further, the housing 41 has an upper elastic connection piece 68, a lower elastic connection piece 69, an upper connection protrusion as a connection portion that holds the housing 41 and the other housing 41 in a connected state by being locked to the other housing 41. 63 and the lower connection protrusion 66 are formed. According to this structure, since the several housing 41 can be hold | maintained in the connected state, the connection state of bus-bars 46 is stabilized. Further, in a state where the housing 41 and the other housing 41 are coupled, the connecting portion between the first connecting portion 47 and the second connecting portion 49 is accommodated in the housing 41 (in the bus bar accommodating chamber 42). Therefore, the connection portion between the bus bars 46 can be protected from foreign matter interference and the like.
　また、本実施例の電源分配装置Ｄは、入力側導電路１０の端末部（接続金具１５）をホルダ２１に取り付けた形態の入力側コネクタ２０を備えている。そして、ホルダ２１と分岐用コネクタ４０のハウジング４１には、互いに係止することで入力側コネクタ２０と分岐用コネクタ４０を連結状態に保持する連結部として、上部弾性連結片６８、下部弾性連結片６９、上部受け突起２３及び下部受け突起２６が形成されていてもよい。この構成によれば、入力側コネクタ２０と分岐用コネクタ４０を連結した状態に保持することができるので、入力側導電路１０とバスバー４６との接続状態が安定する。 Further, the power distribution device D of the present embodiment includes an input side connector 20 in a form in which a terminal portion (connection fitting 15) of the input side conductive path 10 is attached to the holder 21. The holder 21 and the housing 41 of the branching connector 40 are connected to each other so that the input side connector 20 and the branching connector 40 are held in a connected state by being locked together. 69, an upper receiving protrusion 23 and a lower receiving protrusion 26 may be formed. According to this configuration, since the input side connector 20 and the branch connector 40 can be held in a connected state, the connection state between the input side conductive path 10 and the bus bar 46 is stabilized.
　また、分岐用コネクタ４０のハウジング４１と入力側コネクタ２０のホルダ２１を連結した状態では、入力側導電路１０の端末部（接続金具１５）とバスバー４６の第１接続部４７との接続部分が、ハウジング４１のバスバー収容室４２内に収容されている。この構成によれば、入力側導電路１０とバスバー４６との接続部分を、異物の干渉等から保護することができる。 Further, in a state where the housing 41 of the branch connector 40 and the holder 21 of the input side connector 20 are coupled, the connection portion between the terminal portion (connecting bracket 15) of the input side conductive path 10 and the first connection portion 47 of the bus bar 46 is The housing 41 is housed in the bus bar housing chamber 42. According to this configuration, the connection portion between the input side conductive path 10 and the bus bar 46 can be protected from foreign matter interference and the like.
