Thereby, it is possible to sufficiently secure the degree of freedom of bending at the bending portion, which is necessary for absorbing position tolerance and vibration.

＜実施形態２＞
次に、実施形態２を図７〜図１０を参照しつつ説明する。本実施形態の機器コネクタ６０（コネクタに該当）は、撓み部１７に代えて屈曲部６３（曲げ許容部に該当）が配置されている点で実施形態１と異なる。 <Embodiment 2>
Next, Embodiment 2 will be described with reference to FIGS. The device connector 60 (corresponding to a connector) of the present embodiment is different from that of the first embodiment in that a bent portion 63 (corresponding to a bending allowable portion) is arranged instead of the bent portion 17.

バスバー６１は、実施形態１と同様に、基部１１の一端から延びる細長い板状の第１接続部６２を備えている。この第１接続部６２は、図７に示すように、先端側の一部が実施形態１と同様に締結部１６となっており、締結部１６よりも基部１１に近い残りの部分が、屈曲部６３となっている。   As in the first embodiment, the bus bar 61 includes an elongated plate-like first connection portion 62 that extends from one end of the base portion 11. As shown in FIG. 7, the first connecting portion 62 has a part on the distal end side that is the fastening part 16 as in the first embodiment, and the remaining part closer to the base 11 than the fastening part 16 is bent. Part 63 is formed.

屈曲部６３は、図８に示すように、第１接続部６２の延び方向に沿って延び、第１接続部６２の一方の板面から他方の板面まで貫通するスリット６４と、このスリット６４を挟んで並んで配置される２つの板バネ部６５Ａ、６５Ｂとを備えている。図７および図９に示すように、２つの板バネ部６５Ａ、６５Ｂは、互いに反対方向に凸となるように屈曲している。すなわち、２つの板バネ部６５Ａ、６５Ｂのうち一方は、第１接続部６２の一方の板面から突出する（図９の上方に凸となる）山状に屈曲する第１板バネ部６５Ａであり、他方は、第１接続部６２の他方の板面から突出する（図９の下方に凸となる）山状に屈曲する第２板バネ部６５Ｂである。   As shown in FIG. 8, the bent portion 63 extends along the extending direction of the first connection portion 62 and passes through from one plate surface of the first connection portion 62 to the other plate surface, and the slit 64. And two leaf spring portions 65A and 65B arranged side by side. As shown in FIGS. 7 and 9, the two leaf spring portions 65A and 65B are bent so as to protrude in opposite directions. That is, one of the two leaf spring portions 65A and 65B is a first leaf spring portion 65A that protrudes from one plate surface of the first connection portion 62 (bends upward in FIG. 9) and is bent in a mountain shape. The other is a second leaf spring portion 65B that protrudes from the other plate surface of the first connection portion 62 and is bent in a mountain shape (projecting downward in FIG. 9).

このような屈曲部６３は、例えば、バスバー６１に打ち抜き加工を施してスリット６４を形成した後、このスリット６４を挟んで配置される部分にプレス加工を施すことによって板バネ部６５Ａ、６５Ｂを形成してもよいし、あるいは、プレス加工によってスリット６４となる部分をせん断しつつ板バネ部６５Ａ、６５Ｂを形成してもよい。   For example, the bent portion 63 is formed by punching the bus bar 61 to form a slit 64, and then pressing the portion disposed with the slit 64 interposed therebetween to form the leaf spring portions 65A and 65B. Alternatively, the leaf spring portions 65A and 65B may be formed while shearing the portion that becomes the slit 64 by pressing.

その他の構成は実施形態１と同様であるため、実施形態１と同一の構成には同一の符号を付して説明を省略する。   Since other configurations are the same as those of the first embodiment, the same components as those of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

本実施形態においても、板バネ部６５Ａ、６５Ｂを有する屈曲部６３の存在によって、第１接続部６２のある程度の変形が許容されている。したがって、寸法精度の誤差等に起因して、バスバー６１と相手バスバー５０との位置がずれている場合に、図１０に示すように、締結部１６と相手バスバー５０との位置が合うように屈曲部６３を屈曲変形させて、締結部１６を相手バスバー５０に確実に固定し、接続信頼性を確保することができる。   Also in the present embodiment, the first connecting portion 62 is allowed to be deformed to some extent by the presence of the bent portion 63 having the leaf spring portions 65A and 65B. Accordingly, when the positions of the bus bar 61 and the mating bus bar 50 are shifted due to an error in dimensional accuracy, etc., as shown in FIG. 10, the fastening portion 16 and the mating bus bar 50 are bent so that the positions match each other. By bending and deforming the portion 63, the fastening portion 16 can be securely fixed to the mating bus bar 50, and connection reliability can be ensured.
