Description

本発明は、電気接続箱のバスバー取付構造に関する。 The present invention relates to a busbar mounting structure for an electrical junction box.

例えば車両に搭載される電気接続箱として、電気部品であるヒューズを格納するヒューズボックスが知られている（特許文献１参照）。この種のヒューズボックスは、樹脂製のボックス本体（ハウジング本体）と、ボックス本体の上側の開放部を覆う樹脂製のカバー（保護カバー）とを備えており、ヒューズを収容可能に構成されている。 For example, a fuse box that stores fuses, which are electrical components, is known as an electrical connection box mounted on a vehicle (see Patent Document 1). This type of fuse box includes a resin box body (housing body) and a resin cover (protective cover) that covers the opening on the upper side of the box body, and is configured to accommodate a fuse. .

ボックス本体には、ヒューズを収容可能なヒューズ収容部（電気部品格納部）と、ヒューズの２つの端子にそれぞれヒューズ取付部が電気的に接続される第１バスバー及び第２バスバー（第１入出力端子及び第２入出力端子）を収容可能なバスバー収容部（端子収容部）とが、設けられている。そして、これら第１バスバー及び第２バスバーの外部部材取付部（導体接続部）には、外部部材（外部導体）が電気的に接続される。
カバー（保護カバー）は、ボックス本体の開放部のうち、中央部から閉鎖側を覆う第１カバー部（カバー本体）と、中央部から挿入側（外部部材の接続端が挿入される側）を覆う第２カバー部と、第１カバー部と第２カバー部とを接続する薄肉状の連結部と、を備えている。 The box body includes a fuse accommodating part (electrical parts storage part) that can accommodate a fuse, and a first bus bar and a second bus bar (first input/output A bus bar accommodating portion (terminal accommodating portion) that can accommodate the terminal and the second input/output terminal is provided. An external member (external conductor) is electrically connected to the external member attachment portion (conductor connection portion) of the first bus bar and the second bus bar.
The cover (protective cover) includes a first cover part (cover body) that covers the closed side from the center of the open part of the box body, and a first cover part (cover body) that covers the open part of the box body from the center to the closed side, and a first cover part (cover body) that covers the open part of the box body from the center to the insertion side (the side where the connecting end of the external member is inserted). It is provided with a second cover part for covering, and a thin connecting part for connecting the first cover part and the second cover part.

そして、外部部材の接続端が第１バスバー及び第２バスバーの外部部材取付部にそれぞれ接続される際には、第２カバー部だけを回動させてボックス本体の挿入側の上部を開放することができる。即ち、外部部材が接続された後、第２カバー部が閉じられることで、手指等が第１バスバー及び第２バスバーの導体接続部や、外部部材の接続端に触れられない構造となっている。 When the connection ends of the external members are respectively connected to the external member attachment parts of the first bus bar and the second bus bar, only the second cover part is rotated to open the upper part of the insertion side of the box body. I can do it. That is, after the external member is connected, the second cover part is closed, so that fingers, etc. cannot touch the conductor connection part of the first bus bar and the second bus bar, or the connection end of the external member. .

特開２０１８－２６２５１号公報Japanese Patent Application Publication No. 2018-26251

ところで、第１バスバー及び第２バスバーの導体接続部に接続される外部部材としては、車両搭載時のヒューズボックスのレイアウトや仕様に応じて、帯状の平型導体の外周面が絶縁被覆で覆われたバスバー（平型配索材）や、電線端末に接続端子が接続された端子付電線等が用いられる。更に、外部部材の接続端は、第１バスバー及び第２バスバーの導体接続部にネジ締結されるのが一般的であるが、端子付電線の締結方向の高さ（電線径）やネジ締結部の高さは、バスバーの締結方向の高さ（板厚）に比べて高い。 By the way, as an external member connected to the conductor connection part of the first bus bar and the second bus bar, the outer peripheral surface of a band-shaped flat conductor is covered with an insulating coating, depending on the layout and specifications of the fuse box when mounted on a vehicle. Bus bars (flat wiring materials), wires with terminals connected to the ends of the wires, etc. are used. Furthermore, the connecting ends of the external members are generally screwed to the conductor connecting parts of the first bus bar and the second bus bar, but the height (wire diameter) of the terminal-equipped electric wire in the fastening direction and the screw fastening part is higher than the height (plate thickness) of the busbar in the fastening direction.

そこで、第１バスバー及び第２バスバーの導体接続部を覆うカバー（即ち、第２カバー部）は、端子付電線の締結方向の高さ又はネジ締結部の高さに対応して高さが設定されている。
そのため、バスバーの接続端が第１バスバー又は第２バスバーの導体接続部にネジ締結された場合には、バスバーとカバーとの間隙が広くなり、手指等が入り易くなる。そこで、ボックス本体及びカバーには、バスバーの接続端（端末）を覆う範囲を広げる必要が生じ、ヒューズボックスが大型化するという問題があった。 Therefore, the height of the cover that covers the conductor connection parts of the first bus bar and the second bus bar (i.e., the second cover part) is set in accordance with the height of the electric wire with terminal in the fastening direction or the height of the screw fastening part. has been done.
Therefore, when the connecting end of the bus bar is screwed to the conductor connection portion of the first bus bar or the second bus bar, the gap between the bus bar and the cover becomes wider, making it easier for fingers and the like to enter. Therefore, the box body and the cover need to have a wider area to cover the connecting ends (terminals) of the bus bars, resulting in a problem that the fuse box becomes larger.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、電気接続箱内の電気部品に電気的に接続されるバスバーにおける触指防止機能を確実に確保しつつ、電気接続箱が大型化するのを抑制することができる電気接続箱のバスバー取付構造を提供することにある。 The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to secure the tactile prevention function of the bus bar electrically connected to the electrical components in the electrical junction box, and to An object of the present invention is to provide a busbar mounting structure for an electrical junction box that can suppress the increase in size of the electrical junction box.

本実施形態の段差部８５は、バスバー８の端末における導体表出部８４の近傍が導体表出部８４より板厚方向の上方（保護カバー６側）に位置するように、断面クランク状に曲げ加工されている。
即ち、導体表出部８４の近傍が保護カバー６側に向かって屈曲された段差部８５がバスバー８の端末に設けられたことにより、手指自体やスパナ等の工具の入るバスバー８と保護カバー６との間隙が上下方向で分割される。これにより、上下各々の隙間ペースが手指の大きさより小さい隙間となることで、手指が入らない触指防止構造となる。 The stepped portion 85 of this embodiment is bent to have a crank shape in cross section so that the vicinity of the conductor exposed portion 84 at the end of the bus bar 8 is located above the conductor exposed portion 84 in the board thickness direction (on the protective cover 6 side).

次に、ヒューズ２のヒューズ本体２１が電気部品格納部５１に収容される。すると、電気部品格納部５１から左方に突出したヒューズ２の端子２２が第１入出力端子３の端子接続部３１１に重ね合わされ、電気部品格納部５１から右方に突出したヒューズ２の端子２３が第２入出力端子４の端子接続部４１１に重ね合わされる。 Next, the fuse body 21 of the fuse 2 is housed in the electrical component storage section 51. Then, the terminal 22 of the fuse 2 protruding leftward from the electrical component storage section 51 is overlapped with the terminal connection section 311 of the first input/output terminal 3, and the terminal 23 of the fuse 2 protruding rightward from the electrical component storage section 51 is overlapped with the terminal connection section 311 of the first input/output terminal 3. is superimposed on the terminal connection portion 411 of the second input/output terminal 4.

さらに、端子２２の貫通孔２２ａ及び第１入出力端子３の貫通孔３３を挿通したボルト２５がインサートナット５５に螺合され、端子２３の貫通孔２３ａ及び第２入出力端子４の貫通孔４３を挿通したボルト２５がインサートナット５５に螺合される。すると、ヒューズ２と、第１入出力端子３及び第２入出力端子４とが、ハウジング本体５に締結固定される。
そして、図３に示すように、カバー本体６０にカバー７Ａ，７Ｂが開閉自在に取付けられた保護カバー６がハウジング本体５に上方から装着され、電気接続箱１の組み立てが完了する。 Further, the bolt 25 inserted through the through hole 22a of the terminal 22 and the through hole 33 of the first input/output terminal 3 is screwed into the insert nut 55, and the bolt 25 is inserted into the through hole 23a of the terminal 23 and the through hole 43 of the second input/output terminal 4. The bolt 25 inserted therethrough is screwed into the insert nut 55. Then, the fuse 2, the first input/output terminal 3, and the second input/output terminal 4 are fastened and fixed to the housing body 5.
Then, as shown in FIG. 3, the protective cover 6, in which the covers 7A and 7B are attached to the cover body 60 so as to be openable and closable, is attached to the housing body 5 from above, and the assembly of the electrical connection box 1 is completed.

次に、電気接続箱１の第１入出力端子３及び第２入出力端子４にそれぞれ接続されるバスバー８及び端子付電線９の接続手順について図３～図７を参照しながら説明する。
先ず、図３に示すように、電気接続箱１における保護カバー６のカバー７Ａ，７Ｂをそれぞれ開けた状態として、ハウジング本体５における第１端子収容部５３及び第２端子収容部５４の上方を開放する。 Next, a procedure for connecting the bus bar 8 and the terminal-attached electric wire 9 to the first input/output terminal 3 and the second input/output terminal 4 of the electrical connection box 1 will be described with reference to FIGS. 3 to 7.
First, as shown in FIG. 3, the covers 7A and 7B of the protective cover 6 in the electrical junction box 1 are opened, and the upper parts of the first terminal accommodating part 53 and the second terminal accommodating part 54 in the housing body 5 are opened. do.

そして、第１端子収容部５３にバスバー８の端末を載置し、図４に示すように、第１入出力端子３のスタッドボルト３２を導体表出部８４の貫通孔８２に挿通させる。この際、貫通孔８２は、導体表出部８４の延出方向に長い長円形に形成されており、スタッドボルト３２に対するバスバー８の取付位置の寸法公差を吸収することができ、スタッドボルト３２をスムーズに挿通することができる。その後、スタッドボルト３２にナット９７を螺合し、バスバー８の端末を第１端子収容部５３に固定する。この際、段差部８５が折り曲げ形成されている導体表出部８４の近傍は、導体表出部８４より板厚方向の上方（保護カバー６側）に位置することができる。 Then, the end of the bus bar 8 is placed in the first terminal accommodating portion 53, and the stud bolt 32 of the first input/output terminal 3 is inserted into the through hole 82 of the conductor exposed portion 84, as shown in FIG. At this time, the through hole 82 is formed in an oval shape that is elongated in the extending direction of the conductor exposed portion 84, and can absorb the dimensional tolerance of the mounting position of the bus bar 8 with respect to the stud bolt 32. It can be inserted smoothly. Thereafter, a nut 97 is screwed onto the stud bolt 32 to fix the end of the bus bar 8 to the first terminal accommodating portion 53. At this time, the vicinity of the conductor exposed portion 84 where the step portion 85 is bent can be located above the conductor exposed portion 84 in the thickness direction (on the protective cover 6 side).

また、第２端子収容部５４に端子付電線９の接続端子９３を載置し、図４に示すように、第２入出力端子４のスタッドボルト４２を貫通孔９４に挿通させる。その後、スタッドボルト４２にナット９７を螺合し、端子付電線９の接続端子９３を第２端子収容部５４に固定する。 Further, the connecting terminal 93 of the terminal-equipped electric wire 9 is placed in the second terminal accommodating portion 54, and the stud bolt 42 of the second input/output terminal 4 is inserted into the through hole 94, as shown in FIG. Thereafter, a nut 97 is screwed onto the stud bolt 42 to fix the connecting terminal 93 of the terminal-attached electric wire 9 to the second terminal accommodating portion 54 .

そして、保護カバー６のカバー７Ａ，７Ｂをそれぞれ閉じ方向へ回動させ、係止突起７５を係止部６７に係止させることにより、図５に示すように、ハウジング本体５における第１端子収容部５３及び第２端子収容部５４の上方を閉状態とする。
これにより、電気接続箱１の第１入出力端子３及び第２入出力端子４に対するバスバー８及び端子付電線９の接続作業が完了する。 Then, by rotating the covers 7A and 7B of the protective cover 6 in the closing direction and locking the locking protrusion 75 in the locking portion 67, the first terminal is accommodated in the housing body 5, as shown in FIG. The upper portions of the portion 53 and the second terminal accommodating portion 54 are closed.
Thereby, the work of connecting the bus bar 8 and the electric wire 9 with terminals to the first input/output terminal 3 and the second input/output terminal 4 of the electrical junction box 1 is completed.

次に、上記実施形態に係る電気接続箱のバスバー取付構造の作用について説明する。
本実施形態に係る電気接続箱１では、図６に示すように、ハウジング本体５の第１端子収容部５３に収容された第１入出力端子３（導体接続部３１２及びスタッドボルト３２）並びにナット９７は、保護カバー６のカバー７Ａに覆われて手指等の接触が防止される。 Next, the operation of the busbar mounting structure of the electrical connection box according to the above embodiment will be explained.
In the electrical junction box 1 according to the present embodiment, as shown in FIG. 97 is covered by the cover 7A of the protective cover 6 to prevent contact with fingers or the like.

ここで、スタッドボルト３２とナット９７によるネジ締結部の高さは、バスバー８の締結方向の高さ（板厚）に比べて高い。そこで、第１入出力端子３を覆う保護カバー６のカバー７Ａは、ネジ締結部の高さに対応して高さが設定されている。そのため、第１入出力端子３の導体接続部３１２にネジ締結されたバスバー８の導体表出部８４と保護カバー６のカバー７Ａとの間隙が広くなり、手指自体や手に持ったスパナ等の工具が入り易くなっている。 Here, the height of the screw fastening portion formed by the stud bolt 32 and the nut 97 is higher than the height (plate thickness) of the bus bar 8 in the fastening direction. Therefore, the height of the cover 7A of the protective cover 6 that covers the first input/output terminal 3 is set in accordance with the height of the screw fastening portion. Therefore, the gap between the conductor exposed portion 84 of the bus bar 8 screwed to the conductor connection portion 312 of the first input/output terminal 3 and the cover 7A of the protective cover 6 is widened, and the gap between the finger itself and a spanner held in the hand becomes Easy access to tools.

しかしながら、本実施形態に係る電気接続箱のバスバー取付構造では、バスバー８の端末に設けられた段差部８５が、バスバー８と保護カバー６との間隙を上下方向で分割するので、上下各々の隙間ペースが手指の大きさより小さい隙間となる。
そこで、バスバー８と保護カバー６のカバー７Ａとの間隙が段差部８５により狭められるので、図６に示すように、手指を想定したテストフィンガ１００を第１端子収容部５３の外側からバスバー８と保護カバー６のカバー７Ａとの間隙に挿し込んでも、第１入出力端子３（導体接続部３１２及びスタッドボルト３２）、並びにナット９７やバスバー８の導体表出部８４にテストフィンガ１００が達することはない。 However, in the busbar mounting structure of the electrical junction box according to the present embodiment, the stepped portion 85 provided at the terminal of the busbar 8 divides the gap between the busbar 8 and the protective cover 6 in the vertical direction, so the gap between the upper and lower sides is The pace becomes a gap smaller than the size of a finger.
Therefore, since the gap between the bus bar 8 and the cover 7A of the protective cover 6 is narrowed by the step part 85, a test finger 100, which is assumed to be a finger, is inserted into the bus bar 8 from the outside of the first terminal accommodating part 53, as shown in FIG. Even when inserted into the gap between the protective cover 6 and the cover 7A, the test finger 100 does not reach the first input/output terminal 3 (conductor connection portion 312 and stud bolt 32), the nut 97, and the conductor exposed portion 84 of the bus bar 8. There isn't.

また、本実施形態に係る電気接続箱１では、図７に示すように、ハウジング本体５の第２端子収容部５４に収容された第２入出力端子４（導体接続部４１２及びスタッドボルト４２）並びにナット９７は、保護カバー６のカバー７Ｂに覆われて手指等の接触が防止される。 Further, in the electrical junction box 1 according to the present embodiment, as shown in FIG. Further, the nut 97 is covered by the cover 7B of the protective cover 6 to prevent contact with fingers or the like.

ここで、スタッドボルト３２とナット９７によるネジ締結部の高さは、端子付電線９の接続端子９３における圧着部の高さと略同じである。そのため、第２入出力端子４の導体接続部４１２にネジ締結された接続端子９３の圧着部と保護カバー６のカバー７Ｂとの間隙が狭くなり、手指自体や手に持ったスパナ等の工具が入り難くなっている。 Here, the height of the screw fastened portion formed by the stud bolt 32 and the nut 97 is approximately the same as the height of the crimped portion of the connection terminal 93 of the electric wire 9 with a terminal. Therefore, the gap between the crimp part of the connection terminal 93 screwed to the conductor connection part 412 of the second input/output terminal 4 and the cover 7B of the protective cover 6 becomes narrow, and the fingers themselves or tools such as a spanner held in the hand become narrower. It's getting harder to get into.

そこで、図７に示すように、手指を想定したテストフィンガ１００を第２端子収容部５４の外側から端子付電線９と保護カバー６との間隙に挿し込んでも、第２入出力端子４（導体接続部４１２及びスタッドボルト４２）、並びにナット９７や接続端子９３にテストフィンガ１００が達することはない。 Therefore, as shown in FIG. 7, even if a test finger 100, which is assumed to be a finger, is inserted into the gap between the terminal-attached electric wire 9 and the protective cover 6 from the outside of the second terminal accommodating portion 54, the second input/output terminal 4 (conductor The test finger 100 does not reach the connecting portion 412 and the stud bolt 42), the nut 97, or the connecting terminal 93.

図８は、参考例に係るバスバー５０８の要部斜視図である。図９は、図８に示した参考例に係るバスバー５０８を収容した電気接続箱５０１における第１端子収容部５５３の縦断面図である。なお、上記実施形態の電気接続箱１と同様の構成部材については、同符号を付して詳細な説明を省略する。 FIG. 8 is a perspective view of a main part of a bus bar 508 according to a reference example. FIG. 9 is a longitudinal cross-sectional view of the first terminal accommodating portion 553 in the electrical connection box 501 that accommodates the bus bar 508 according to the reference example shown in FIG. Note that the same components as those of the electrical connection box 1 of the above embodiment are given the same reference numerals and detailed explanations will be omitted.

図８に示すように、参考例に係るバスバー５０８は、段差部８５が折り曲げ形成されておらず、バスバー８の端末における導体表出部８４の近傍が導体表出部８４と同一の平面上に位置している。
そこで、参考例に係る電気接続箱５０１では、図９に示すように、第１入出力端子３の導体接続部３１２にネジ締結されたバスバー５０８の端末と保護カバー６のカバー７Ａとの間隙が広くなっており、上記実施形態で説明したような段差部８５により間隙が狭められていない。そのため、手指を想定したテストフィンガ１００を第１端子収容部５５３の外側からバスバー５０８と保護カバー６のカバー７Ａとの間隙に挿し込むと、第１入出力端子３（導体接続部３１２及びスタッドボルト３２）、並びにナット９７やバスバー５０８の導体表出部８４にテストフィンガ１００が達することがある。 As shown in FIG. 8, in the bus bar 508 according to the reference example, the step portion 85 is not bent and the vicinity of the conductor exposed portion 84 at the terminal of the bus bar 8 is on the same plane as the conductor exposed portion 84. positioned.
Therefore, in the electrical junction box 501 according to the reference example, as shown in FIG. The gap is wide, and the gap is not narrowed by the stepped portion 85 as described in the above embodiment. Therefore, when the test finger 100, which is assumed to be a finger, is inserted into the gap between the bus bar 508 and the cover 7A of the protective cover 6 from the outside of the first terminal accommodating part 553, the first input/output terminal 3 (the conductor connection part 312 and the stud bolt 32), as well as the nut 97 and the conductor exposed portion 84 of the bus bar 508.

したがって、本実施形態に係る電気接続箱１のバスバー取付構造によれば、電気接続箱１内のヒューズ２に電気的に接続されるバスバー８における触指防止機能を確実に確保することができる。
また、ハウジング本体５及び保護カバー６は、バスバー８の導体表出部８４（端末）を覆う範囲を広げる必要がなくなり、電気接続箱１が大型化するのを抑制することができる。 Therefore, according to the busbar mounting structure of the electrical connection box 1 according to the present embodiment, the tactile prevention function of the busbar 8 electrically connected to the fuse 2 in the electrical connection box 1 can be ensured.
Further, the housing body 5 and the protective cover 6 do not need to extend the range of covering the conductor exposed portion 84 (terminal) of the bus bar 8, and it is possible to suppress the electrical connection box 1 from increasing in size.

更に、本実施形態に係る保護カバー６のカバー７Ｂは、第２入出力端子４の導体接続部４１２に接続される外部導体として端子付電線９を用いた場合でも、バスバー８が接続される第１入出力端子３の導体接続部３１２を覆うカバー７Ａと同形状に形成することができる。そこで、部品を共用化して製造コストの低減を図ることができる。 Furthermore, the cover 7B of the protective cover 6 according to the present embodiment is designed to cover the first terminal to which the bus bar 8 is connected even when the terminal-attached electric wire 9 is used as the external conductor to be connected to the conductor connection portion 412 of the second input/output terminal 4. It can be formed in the same shape as the cover 7A that covers the conductor connection portion 312 of the input/output terminal 3. Therefore, manufacturing costs can be reduced by sharing parts.

図１０及び図１１は、変形例に係るバスバー８Ａ及び他の変形例に係るバスバー８Ｂの要部斜視図である。なお、上記実施形態のバスバー８と同様の構成部材については、同符号を付して詳細な説明を省略する。
図１０に示すように、変形例に係るバスバー８Ａの端末における導体表出部８４の近傍には、バスバー８Ａと保護カバー６との間隙を狭めて手指が第１端子収容部５３内に入ることを防止するように段差部８５Ａが折り曲げ形成されている。 10 and 11 are perspective views of main parts of a bus bar 8A according to a modification and a bus bar 8B according to another modification. Note that components similar to those of the bus bar 8 of the above embodiment are given the same reference numerals and detailed explanations will be omitted.
As shown in FIG. 10, near the conductor exposed portion 84 at the terminal of the bus bar 8A according to the modification, the gap between the bus bar 8A and the protective cover 6 is narrowed so that fingers can enter the first terminal accommodating portion 53. The stepped portion 85A is bent to prevent this.

変形例の段差部８５Ａは、バスバー８Ａの端末における導体表出部８４の近傍が導体表出部８４より板厚方向の上方（保護カバー６側）に位置するように、断面階段状に曲げ加工されている。
即ち、導体表出部８４の近傍が保護カバー６側に向かって屈曲された段差部８５Ａがバスバー８Ａの端末に設けられたことにより、手指自体やスパナ等の工具が入るバスバー８Ａと保護カバー６のカバー７Ａとの間隙が上下方向で分割される。これにより、上下各々の隙間ペースが手指の大きさより小さい隙間となることで、手指が入らない触指防止構造となる。 The stepped portion 85A of the modified example is bent to have a stepped cross section so that the vicinity of the conductor exposed portion 84 at the end of the bus bar 8A is located above the conductor exposed portion 84 in the thickness direction (on the protective cover 6 side). has been done.
That is, by providing a step portion 85A in which the vicinity of the conductor exposed portion 84 is bent toward the protective cover 6 side at the terminal of the bus bar 8A, the bus bar 8A and the protective cover 6 into which fingers and tools such as spanners can be inserted are provided. The gap between the cover 7A and the cover 7A is divided in the vertical direction. As a result, each of the upper and lower gaps is smaller than the size of a finger, resulting in a finger-preventing structure that prevents fingers from entering.

図１１に示すように、他の変形例に係るバスバー８Ｂの端末における導体表出部８４の近傍には、バスバー８Ｂと保護カバー６との間隙を狭めて手指が第１端子収容部５３内に入ることを防止するように段差部８５Ｂが折り曲げ形成されている。
他の変形例の段差部８５Ｂは、折り曲げ部が保護カバー６側に向かうように断面Ω字状に屈曲されて、バスバー８Ｂと保護カバー６のカバー７Ａとの間隙に突出する。 As shown in FIG. 11, in the vicinity of the conductor exposed portion 84 at the terminal of the bus bar 8B according to another modification, the gap between the bus bar 8B and the protective cover 6 is narrowed so that the fingers can be placed inside the first terminal accommodating portion 53. The stepped portion 85B is formed by bending to prevent it from entering.
The stepped portion 85B of another modification is bent into an Ω-shaped cross section so that the bent portion faces the protective cover 6 side, and protrudes into the gap between the bus bar 8B and the cover 7A of the protective cover 6.

即ち、導体表出部８４の近傍が保護カバー６側に向かって屈曲された段差部８５Ｂがバスバー８Ｂの端末に設けられたことにより、バスバー８Ｂと保護カバー６のカバー７Ａとの間隙が段差部８５Ｂにより閉塞される。これにより、段差部８５Ｂが手指自体やスパナ等の工具の挿入を阻止することで、手指が入らない触指防止構造となる。 That is, since the stepped portion 85B in which the vicinity of the conductor exposed portion 84 is bent toward the protective cover 6 side is provided at the end of the bus bar 8B, the gap between the bus bar 8B and the cover 7A of the protective cover 6 is reduced to a stepped portion. 85B. As a result, the stepped portion 85B prevents the insertion of fingers or tools such as spanners, resulting in a structure that prevents fingers from entering.

したがって、これらバスバー８Ａ又はバスバー８Ｂを備えた電気接続箱１のバスバー取付構造によれば、電気接続箱１内のヒューズ２に電気的に接続されるバスバー８Ａ又はバスバー８Ｂにおける触指防止機能を確実に確保することができる。
また、ハウジング本体５及び保護カバー６は、バスバー８Ａ又はバスバー８Ｂの導体表出部８４（端末）を覆う範囲を広げる必要がなくなり、電気接続箱１が大型化するのを抑制することができる。 Therefore, according to the busbar mounting structure of the electrical junction box 1 equipped with these busbars 8A or 8B, the tactile prevention function of the busbar 8A or the busbar 8B electrically connected to the fuse 2 in the electrical junction box 1 is ensured. can be secured.
Further, the housing body 5 and the protective cover 6 do not need to extend the range to cover the conductor exposed portion 84 (terminal) of the bus bar 8A or the bus bar 8B, and it is possible to suppress the electrical connection box 1 from increasing in size.

を備える電気接続箱のバスバー取付構造。 Here, the features of the embodiments of the busbar mounting structure for an electrical junction box according to the present invention described above are briefly summarized and listed below in [1] to [6].
[1] Accommodates an electrical component storage section (51) that stores an electrical component (fuse 2) and a first input/output terminal (3) that is electrically connected to the terminal (22) of the electrical component (fuse 2). an electrically insulating housing body (5) in which a first terminal accommodating portion (53) is formed, and a housing that covers the terminal (22) of the electrical component (fuse 2) and the first input/output terminal (3). an electrical junction box (1) having a protective cover (6) attached to the housing body (5);
The outer peripheral surface of the strip-shaped flat conductor (81) is covered with an insulating coating (83), and the conductor exposed portion (84) at the terminal is electrically connected to the conductor connection portion (312) of the first input/output terminal (3). bus bars (8, 8A, 8B) connected to the
The bus bars (8, 8A, 8B) are designed to narrow the gap between the bus bars (8, 8A, 8B) and the protective cover (6) to prevent fingers from entering the first terminal accommodating portion (53). ) formed in the step portions (85, 85A, 85B);
A busbar mounting structure for an electrical junction box.

上記［１］の構成の電気接続箱のバスバー取付構造によれば、ハウジング本体（５）の第１端子収容部（５３）に収容された第１入出力端子（３）は、保護カバー（６）に覆われて手指等の接触が防止される。
ここで、帯状の平型導体（８１）により形成されたバスバー（８）の端末は、第１入出力端子（３）の導体接続部（３１２）にネジ締結されるのが一般的であるが、ネジ締結部の高さはバスバー（８）の締結方向の高さ（板厚）に比べて高い。そこで、第１入出力端子（３）を覆う保護カバー（６）は、ネジ締結部の高さに対応して高さが設定されている。そのため、バスバー（８）の端末が第１入出力端子（３）の導体接続部（３１２）にネジ締結された場合には、バスバー（８）と保護カバー（６）との間隙が広くなり、手指自体や手に持ったスパナ等の工具が入り易くなる。
しかしながら、上記［１］の構成の電気接続箱のバスバー取付構造によれば、バスバー（８，８Ａ，８Ｂ）に形成された段差部（８５，８５Ａ，８５Ｂ）が、バスバー（８，８Ａ，８Ｂ）と保護カバー（６）との間隙を狭める。そこで、手指自体やスパナ等の工具は第１入出力端子（３）やバスバー（８，８Ａ，８Ｂ）の導体表出部（８４）に触れることが出来なくなる。
したがって、電気接続箱（１）内の電気部品（ヒューズ２）に電気的に接続されるバスバー（８，８Ａ，８Ｂ）における触指防止機能を確実に確保することができる。また、ハウジング本体（５）及び保護カバー（６）は、バスバー（８，８Ａ，８Ｂ）の導体表出部（８４）（端末）を覆う範囲を広げる必要がなくなり、電気接続箱（１）が大型化するのを抑制することができる。 According to the busbar mounting structure of the electrical junction box configured in [1] above, the first input/output terminal (3) accommodated in the first terminal accommodating portion (53) of the housing body (5) is connected to the protective cover (6). ) to prevent contact with fingers, etc.
