かしめ片17は、底板部16の幅方向の両縁に連なっている。かしめ片17は、底板部16に近づく方向に曲げられて、該底板部16との間に電線18を挟む。こうして、かしめ片17は、電線18を加締める。電線接続部15は、かしめ片17が電線18を加締めることで、該電線18が取り付けられるとともに、電線18と電気的に接続される。   The caulking pieces 17 are continuous with both edges in the width direction of the bottom plate portion 16. The caulking piece 17 is bent in a direction approaching the bottom plate portion 16, and the electric wire 18 is sandwiched between the bottom plate portion 16. Thus, the caulking piece 17 crimps the electric wire 18. The electric wire connecting portion 15 is electrically connected to the electric wire 18 while the electric wire 18 is attached by the caulking piece 17 caulking the electric wire 18.

前述した端子金具3は、図1に示すように、電線接続部15に電線18が取り付けられた状態で、電線接続部15及び電線18が凹溝14,30内に収容されて、電気接触部11が端子取付部に取り付けられる。このとき、電気接触部11は、端子取付部に重ねられ、孔12内にねじ部が通されたボルト10がナットに螺合することで、端子取付部則ち上面に取り付けられる。また、電気接触部11の長手方向は、前述した凹溝14,30が設けられた外壁13,28の外壁面13a,28aと平行となる。また、端子金具3に取り付けられる電線18は、図示例では、バッテリなどの電源に接続する。   As shown in FIG. 1, the terminal fitting 3 described above has the electric wire connecting portion 15 and the electric wire 18 accommodated in the concave grooves 14 and 30 in the state where the electric wire 18 is attached to the electric wire connecting portion 15, and the electric contact portion. 11 is attached to the terminal attachment portion. At this time, the electrical contact portion 11 is overlaid on the terminal mounting portion, and the bolt 10 having the threaded portion in the hole 12 is screwed into the nut, thereby being attached to the terminal mounting portion, that is, the upper surface. Further, the longitudinal direction of the electrical contact portion 11 is parallel to the outer wall surfaces 13a and 28a of the outer walls 13 and 28 provided with the above-described concave grooves 14 and 30. Moreover, the electric wire 18 attached to the terminal metal fitting 3 is connected to power supplies, such as a battery, in the example of illustration.

サイドカバー4は、絶縁性の合成樹脂からなり、周知の射出成形により成形される。サイドカバー4は、図1及び図2に示すように、断面コの字状の本体部19と、案内部としての複数のリブ33,34と、を一体に備えている。本体部19は、平面形状が前述した凹溝14,30の平面形状と略等しい矩形状に形成されている。   The side cover 4 is made of an insulating synthetic resin and is formed by a known injection molding. As shown in FIGS. 1 and 2, the side cover 4 integrally includes a main body portion 19 having a U-shaped cross section and a plurality of ribs 33 and 34 as guide portions. The main body 19 is formed in a rectangular shape whose planar shape is substantially equal to the planar shape of the concave grooves 14 and 30 described above.

案内部としての複数対のリブ33,34は、本体部19の縁から立設している。一対のリブ33と一対のリブ34は、本体部19の長手方向の両縁それぞれに設けられている。一対のリブ33と一対のリブ34は、本体部19の幅方向の縁から該本体部19の外方向に向かって突出している。一対のリブ33は、本体部19の長手方向の一端側に設けられている。一対のリブ34は、本体部19の長手方向の他端側に設けられている。リブ33,34は、本体部19の長手方向則ち矢印Kに沿って直線状に延びている。リブ33,34は、本体部19の長手方向則ち矢印Kに沿って互いに間隔をあけて配されている。   A plurality of pairs of ribs 33 and 34 as guide portions are erected from the edge of the main body portion 19. The pair of ribs 33 and the pair of ribs 34 are provided on both edges in the longitudinal direction of the main body 19. The pair of ribs 33 and the pair of ribs 34 protrude from the edge in the width direction of the main body 19 toward the outside of the main body 19. The pair of ribs 33 is provided on one end side in the longitudinal direction of the main body 19. The pair of ribs 34 is provided on the other end side in the longitudinal direction of the main body 19. The ribs 33, 34 extend linearly along the longitudinal direction of the main body 19, that is, along the arrow K. The ribs 33 and 34 are spaced apart from each other along the longitudinal direction of the main body 19, that is, the arrow K.

リブ33,34は、スライド溝21,31内に侵入することで、サイドカバー4を本体部19の表面に沿ってスライドさせる(以下、この方向をスライド方向Kとする)。リブ33,34が本体部19の表面に沿って直線状に延びており、なおかつ、スライド溝21,31内に侵入するので、サイドカバー4をスライド方向Kに沿って案内する。なお、スライド方向Kは、前述した箱本体2とロアカバー26とが互いに重なる方向Kと同じ向きである。   The ribs 33 and 34 enter the slide grooves 21 and 31 to slide the side cover 4 along the surface of the main body 19 (hereinafter, this direction is referred to as a slide direction K). Since the ribs 33 and 34 extend linearly along the surface of the main body 19 and enter the slide grooves 21 and 31, the side cover 4 is guided along the slide direction K. The sliding direction K is the same direction as the direction K in which the box body 2 and the lower cover 26 overlap each other.

前述したサイドカバー4は、リブ33が、矢印Kに沿ってスライド溝21内にスライドし、リブ34が、図4に示すように、矢印Kに沿ってスライド溝31内にスライドすると、箱本体2に取り付けられる。また、本体部19則ちサイドカバー4は、箱本体2に取り付けられると、前述した凹溝14が設けられた外壁13の外壁面13aと略面一になるとともに、前述した凹溝14の外壁13における開口を塞ぐ。こうして、本体部19則ちサイドカバー4は、箱本体2に取り付けられると、前述した凹溝14及び凹溝30を塞ぐ。また、本体部19則ちサイドカバー4は、箱本体2及びロアカバー26に取り付けられると、前述した凹溝14の前述した上面2a及び下面側の開口を塞がない(開放する)。   When the rib 33 slides in the slide groove 21 along the arrow K and the rib 34 slides in the slide groove 31 along the arrow K as shown in FIG. 2 is attached. Further, when the body portion 19, that is, the side cover 4 is attached to the box body 2, the body portion 19 is substantially flush with the outer wall surface 13 a of the outer wall 13 provided with the aforementioned recessed groove 14 and the outer wall of the aforementioned recessed groove 14. The opening at 13 is closed. Thus, when the main body 19, that is, the side cover 4 is attached to the box main body 2, the concave groove 14 and the concave groove 30 described above are closed. Further, when the main body 19, that is, the side cover 4 is attached to the box main body 2 and the lower cover 26, the opening on the upper surface 2 a and the lower surface side of the groove 14 described above is not blocked (opened).

前述した電気接続箱1は、以下のように組み立てられる。まず、箱本体2内に配線盤を収容し、箱本体2の上面2aに設けられた装着部8aにヒュージブルリンクやリレー5などの電気部品が装着される。そして、凹溝14内に端子金具3が取り付けられた電線18を収容し、該端子金具3の電気接触部11の長手方向を凹溝14が設けられた外壁13の外壁面13aと平行にし、電気接触部11を端子取付部に重ねる。そして、孔12内にねじ部を通して、ボルト10を端子取付部のナットに螺合する。こうして、端子金具3を端子取付部に固定する。すると、凹溝14内に電線18と端子金具3の電線接続部15とを収容する。   The electrical junction box 1 described above is assembled as follows. First, a wiring board is accommodated in the box body 2, and electrical components such as a fusible link and a relay 5 are mounted on a mounting portion 8 a provided on the upper surface 2 a of the box body 2. And the electric wire 18 to which the terminal fitting 3 is attached is accommodated in the concave groove 14, the longitudinal direction of the electrical contact portion 11 of the terminal fitting 3 is made parallel to the outer wall surface 13a of the outer wall 13 provided with the concave groove 14, The electric contact part 11 is overlaid on the terminal mounting part. Then, the bolt 10 is screwed into the nut of the terminal mounting portion through the screw portion in the hole 12. Thus, the terminal fitting 3 is fixed to the terminal mounting portion. Then, the electric wire 18 and the electric wire connection part 15 of the terminal metal fitting 3 are accommodated in the concave groove 14.

そして、図2に示すように、サイドカバー4のリブ33を、矢印Kに沿って、スライド溝21内に挿入させ、リブ34を、矢印Kに沿って、スライド溝31内に挿入させて、サイドカバー4を凹溝14,30内に案内する。そうして、スライド溝21が、リブ33をスライド溝21の内面間に挟んで、リブ33を固定し、スライド溝31が、図4に示すように、リブ34をスライド溝21の内面と突起32との間に挟んで、リブ34を位置付ける。則ち、スライド溝21が、リブ33と嵌合するとともに、スライド溝31が、リブ34と嵌合すると、サイドカバー4を箱本体2及びロアカバー26に取り付ける。すると、サイドカバー4が凹溝14を塞ぐ。こうして、図3に示すように、前述した構成の電気接続箱1が組み立てられる。そして、電気接続箱1は、箱本体2の下面にワイヤハーネスのコネクタを嵌合するなどして、自動車に搭載される。そして、電気接続箱1は、自動車の電子機器と、ヒュージブルリンクやリレー5などの電気部品などとを、予め定められたパターンにしたがって、互いに電気的に接続する。   Then, as shown in FIG. 2, the rib 33 of the side cover 4 is inserted into the slide groove 21 along the arrow K, and the rib 34 is inserted into the slide groove 31 along the arrow K. The side cover 4 is guided into the concave grooves 14 and 30. Then, the slide groove 21 fixes the rib 33 by sandwiching the rib 33 between the inner surfaces of the slide groove 21, and the slide groove 31 projects the rib 34 from the inner surface of the slide groove 21 as shown in FIG. The ribs 34 are positioned between them. That is, when the slide groove 21 is fitted to the rib 33 and the slide groove 31 is fitted to the rib 34, the side cover 4 is attached to the box body 2 and the lower cover 26. Then, the side cover 4 closes the concave groove 14. Thus, as shown in FIG. 3, the electrical junction box 1 having the above-described configuration is assembled. The electrical connection box 1 is mounted on the automobile by fitting a wire harness connector to the lower surface of the box body 2. And the electrical junction box 1 electrically connects the electronic device of a motor vehicle, electrical parts, such as a fusible link and the relay 5, with each other according to a predetermined pattern.

本実施形態によれば、サイドカバー4に設けられ、サイドカバー4のスライド方向Kを案内するリブ33,34が、サイドカバー4のスライド方向Kに沿って互いに間隔をあけて配置され、リブ33が嵌合するスライド溝21と、リブ34が嵌合するスライド溝31とが、箱本体2とロアカバー26とに設けられているので、リブ33をスライド溝21に、リブ34をスライド溝31にそれぞれスライドさせて、サイドカバー4を取り付ける際に、サイドカバー4を移動させる距離(ストローク)が短くなり、サイドカバー4を容易に組付けることができる。したがって、本発明の電気接続箱1は、サイドカバー4を短い移動行程で容易に組付けることができる。   According to the present embodiment, the ribs 33 and 34 that are provided on the side cover 4 and guide the sliding direction K of the side cover 4 are arranged at intervals along the sliding direction K of the side cover 4. Since the box body 2 and the lower cover 26 are provided with the slide groove 21 into which the rib 34 is fitted and the slide groove 31 into which the rib 34 is fitted, the rib 33 is used as the slide groove 21 and the rib 34 is used as the slide groove 31. When the side cover 4 is attached by sliding, the distance (stroke) for moving the side cover 4 is shortened, and the side cover 4 can be easily assembled. Therefore, the electrical junction box 1 of the present invention can easily assemble the side cover 4 with a short moving stroke.

また、スライド溝21が箱本体2に設けられ、スライド溝31がロアカバー26にそれぞれ設けられているので、サイドカバー4が取り付けられる間の距離が長くなり、サイドカバー4が取り付けられた際のサイドカバー4のガタが少なくなる。したがって、本発明の電気接続箱1は、サイドカバー4を確実に組付けることができる。   Further, since the slide groove 21 is provided in the box body 2 and the slide groove 31 is provided in the lower cover 26, the distance during which the side cover 4 is attached becomes longer, and the side when the side cover 4 is attached is increased. The backlash of the cover 4 is reduced. Therefore, the side cover 4 can be reliably assembled to the electrical junction box 1 of the present invention.
