以下に上記ジョイントボックス１を用いた電線配索方法（ジョイントボックス１の電線配索構造）について説明する。 Below, the electric wire arrangement method (electric wire arrangement structure of the joint box 1) using the said joint box 1 is demonstrated.

先ず図４の如く、カバー５を外した状態でベース６のジョイント部７の各溝部１０に各電線（絶縁被覆電線）９を配置し、図示しない圧接治具を用いて各電線９を溝部内の各圧接端子３に圧接する。本例で後半の二本の電線（本線）９₁のうちの一方は＋極の第一のバスバー、他方は−極の第二のバスバーに接続され、前半の二本の電線（分岐線）９₂のうちの一方は＋極の第一のバスバー、他方は−極の第二のバスバーに接続され、−極の第二のバスバーはアース端子４に続いている。 First, as shown in FIG. 4, each electric wire (insulated coated electric wire) 9 is arranged in each groove portion 10 of the joint portion 7 of the base 6 with the cover 5 removed, and each electric wire 9 is placed in the groove portion using a pressure welding jig (not shown). The pressure contact terminals 3 are pressed against each other. The first bus bar of the second half of the two wires (mains) 9 while the positive pole of the _one in the present embodiment, the other - is connected to the second bus bar electrode, the first half of the two wires (branch line) One of the 9 ₂ is connected to the positive first bus bar, the other is connected to the negative second bus bar, and the negative second bus bar continues to the ground terminal 4.

電線圧接後に図５の如く、カバー５の第一カバー部２２のみをベース６に閉止させて、第一カバー部２２でジョイント部７を覆って保護する。前述の如く第一カバー部２２の左右端で各電線９がベース６に押圧固定され、電線６の引張力が圧接部（圧接端子３と電線９との接続部）に及ぶことが防止される。第一カバー部２２は前後の係止手段２１，２７、１７，２９でベース６に係止される。第二カバー部２３は開いたままである。 As shown in FIG. 5, only the first cover portion 22 of the cover 5 is closed to the base 6 after the wire pressure welding, and the joint portion 7 is covered and protected by the first cover portion 22. As described above, the electric wires 9 are pressed and fixed to the base 6 at the left and right ends of the first cover portion 22, and the tensile force of the electric wires 6 is prevented from reaching the pressure contact portion (the connection portion between the pressure contact terminal 3 and the wire 9). . The first cover portion 22 is locked to the base 6 by the front and rear locking means 21, 27, 17, and 29. The second cover part 23 remains open.

第一カバー２２を閉止した後に図６の如く、ベース６の電線挿通部８内に、圧接しない電線４０を真直な状態で配置すると共に、圧接済みの電線９の一部（本例では分岐線９₂）をＵ字状に折り返して配置して、第二カバー部２３を閉止する。第二カバー部２３は位置決め手段１８，３３で位置決めされつつ係止手段１９，３４でベース６に係止される。電線挿通部８内の電線４０，９₂は特に固定されずに挿通されるのみである（長手方向に移動可能で径方向にほぼ不動に固定される）。電線４０は種々の太さのものを使用可能である。 After the first cover 22 is closed, as shown in FIG. 6, a non-pressure-bonded electric wire 40 is placed in a straight state in the electric wire insertion portion 8 of the base 6, and a part of the pressure-bonded electric wire 9 (in this example, a branch line) 9 ₂ ) is folded back in a U shape, and the second cover portion 23 is closed. The second cover portion 23 is locked to the base 6 by the locking means 19 and 34 while being positioned by the positioning means 18 and 33. Wire 40, 9 ₂ in the wire insertion portion 8 is only inserted without particular fixed (longitudinal direction is substantially immovably secured to the possible radial movement in). The electric wire 40 can have various thicknesses.

このようにして、ジョイントの必要な電線９とその必要のない電線４０とがジョイントボックス１内に分離して又は混合して配索される。 In this way, the electric wires 9 that need joints and the electric wires 40 that do not need to be separated and mixed are arranged in the joint box 1.

圧接接続を行う電線９に関しては、品質等の問題に鑑み、圧接作業を行った場所から圧接した電線９を動かさずに固定してしまうことが理想である。従って、本発明では、先ず電線圧接後に第一カバー部２２を直ぐに装着し、ジョイント部７と第一カバー部２２とにより電線９を挟んで固定し、圧接端子（圧接刃）３にテンションがかからないようにしている。そして、別の工程で他の電線４０を電線挿通部８に収容し、第二カバー部２３を装着している。 With regard to the electric wire 9 that performs the press-contact connection, in view of problems such as quality, it is ideal that the electric wire 9 that is press-contacted from the place where the press-contact operation is performed is fixed without moving. Therefore, in the present invention, the first cover portion 22 is first mounted immediately after the wire pressure welding, and the wire 9 is sandwiched and fixed by the joint portion 7 and the first cover portion 22 so that the pressure contact terminal (pressure contact blade) 3 is not tensioned. I am doing so. Then, another electric wire 40 is accommodated in the electric wire insertion portion 8 and the second cover portion 23 is attached in another process.

圧接作業を行った場所で、圧接を行った電線９と、電線挿通部８に収容される電線４０とをヒンジ３０を介さない別体のカバー（図示せず）で一気に覆ってしまうことも可能ではあるが、慎重な作業を必要とする圧接作業に、圧接に関係ない作業を含めたくないことから、本発明では二つの工程で別々に電線９，４０の配索を行っている。このような作業に、本発明のヒンジ３０を介して前後のカバー部２２，２３を連結したカバー５が有効となる。 It is also possible to cover the wire 9 subjected to the pressure welding and the wire 40 accommodated in the wire insertion portion 8 at a place where the pressure welding work is performed with a separate cover (not shown) that does not include the hinge 30 at a stretch. However, since it is not desired to include work not related to pressure welding in the pressure welding work that requires careful work, in the present invention, the wires 9, 40 are routed separately in two steps. For such operations, the cover 5 in which the front and rear cover portions 22 and 23 are connected via the hinge 30 of the present invention is effective.
