ところで、特許文献１では、１個の端子に１本の電線が接続された端子付き電線であるが、これとは異なり、１個の端子に対して複数の電線が接続された端子付き電線とすることも想定される。この場合、複数の電線を一括して保護被覆で覆うと、保護被覆の内面側の接着剤が隣り合う電線間に浸透せず、例えば熱収縮チューブの開口端における隣り合う電線間から水が浸入して十分な防水性能を確保することができないことが懸念される。   By the way, in patent document 1, although it is an electric wire with a terminal where one electric wire was connected to one terminal, unlike this, an electric wire with a terminal where a plurality of electric wires were connected to one terminal, It is also assumed that In this case, if a plurality of electric wires are covered with a protective coating, the adhesive on the inner surface side of the protective coating does not penetrate between adjacent electric wires, for example, water penetrates between adjacent electric wires at the open end of the heat shrinkable tube. There is a concern that sufficient waterproof performance cannot be ensured.

Has characteristics.

本発明によれば、隣り合う複数の電線間に接着部材が配された状態で保護被覆が被せられているため、隣り合う複数の電線間の接着部材により隣り合う電線間を通って導体部と端子との接続部分へ水が浸入することを防止できる。よって、端子付き電線の防水性を向上させることが可能となる。   According to the present invention, since the protective coating is put in a state where the adhesive member is arranged between the plurality of adjacent electric wires, the conductor portion and the conductor portion pass between the adjacent electric wires by the adhesive member between the plurality of adjacent electric wires. Water can be prevented from entering the connecting portion with the terminal. Therefore, the waterproofness of the electric wire with terminal can be improved.

The connection part 17 consists of a cyclic | annular metal plate material, and the circular connection hole has penetrated in the center part.

電線接続部１８は、電線１１の端末部が接続される部分であり、接続部１７の後方に連なり複数の電線１１が載置される底板１９を有し、底板１９からワイヤバレル２０とインシュレーションバレル２２とが立ち上げられている。   The electric wire connecting portion 18 is a portion to which the terminal portion of the electric wire 11 is connected. The electric wire connecting portion 18 includes a bottom plate 19 that is connected to the rear of the connecting portion 17 and on which the plurality of electric wires 11 are placed. A barrel 22 is set up.

As a metal which comprises a plating layer, arbitrary metals, such as tin and nickel, can be employ | adopted as needed. In the present embodiment, a tin plating layer is formed on the surface of copper or a copper alloy. In addition, it is good also as a structure which does not form a plating layer on the surface of a metal plate material.

端子１６と電線１１との接続部分には、図１に示すように、熱収縮チューブ２４が被せられている。熱収縮チューブ２４は、筒状であって、図４に示すように、端子１６の接続部１７の後方（導体部１２の前方）の位置から接着部材１４の後方の絶縁被覆１３を有する位置までを覆うものである。   As shown in FIG. 1, a heat-shrinkable tube 24 is put on the connection portion between the terminal 16 and the electric wire 11. As shown in FIG. 4, the heat shrinkable tube 24 has a cylindrical shape, from the position behind the connection portion 17 of the terminal 16 (front of the conductor portion 12) to the position having the insulating coating 13 behind the adhesive member 14.

この熱収縮チューブ２４は、図５に示すように、加熱処理によって収縮する２層の合成樹脂材料からなり、外層２４Ａは、例えば、ポリオレフィン樹脂及びその変成物であり、内層２４Ｂは、例えば、ＥＶＡ（エチレンビニルアルコール），ＰＡ（ポリアミド），ポリエステル系接着剤等からなる熱溶融性接着剤である。熱溶融性接着剤は、加熱によって軟化又は溶融することにより接着性を発現する、熱可塑性の接着剤（接着層）である。   As shown in FIG. 5, the heat-shrinkable tube 24 is made of a two-layer synthetic resin material that shrinks by heat treatment, the outer layer 24A is, for example, a polyolefin resin and a modified product thereof, and the inner layer 24B is, for example, EVA. It is a hot-melt adhesive made of (ethylene vinyl alcohol), PA (polyamide), polyester-based adhesive and the like. The hot-melt adhesive is a thermoplastic adhesive (adhesive layer) that develops adhesiveness when softened or melted by heating.

次に、本実施形態に係る端子付き電線１０の製造工程を説明する。
金属板材に打ち抜き加工、曲げ加工を施して端子１６を形成し、圧着金型に載置した端子１６の電線接続部１８に電線１１を配して圧着することで、電線１１と端子１６とが接続される（図２）。 Next, the manufacturing process of the electric wire 10 with a terminal which concerns on this embodiment is demonstrated.
The metal plate material is punched and bent to form the terminal 16, and the electric wire 11 is arranged and crimped to the electric wire connecting portion 18 of the terminal 16 placed on the crimping die so that the electric wire 11 and the terminal 16 are connected. Connected (FIG. 2).

そして、一方の電線１１に接着部材１４を装着する。この接着部材１４は、切れ目部１５以外の部分（分断されていない部分）が隣り合う電線１１間に配されるように装着する。
なお、この接着部材１４を装着した後に、上記した電線１１を端子１６に圧着する作業を行うようにしてもよい。 Then, the adhesive member 14 is attached to one electric wire 11. The adhesive member 14 is mounted so that a portion other than the cut portion 15 (a portion that is not divided) is disposed between the adjacent electric wires 11.
In addition, after mounting | wearing this adhesive member 14, you may make it perform the operation | work which crimps | bonds the above-mentioned electric wire 11 to the terminal 16. FIG.

そして、端子１６が圧着された電線１１に、収縮前の筒状の熱収縮チューブ２４を所定位置まで挿通し（図４）、図示しない加熱装置に挿通して加熱して熱収縮チューブ２４を熱収縮させる。このときの熱により、熱収縮チューブ２４の内面の接着層が溶ける。   Then, the tubular heat-shrinkable tube 24 before shrinkage is inserted into the electric wire 11 to which the terminals 16 are crimped to a predetermined position (FIG. 4), and is passed through a heating device (not shown) and heated to heat the heat-shrinkable tube 24. Shrink. The heat at this time melts the adhesive layer on the inner surface of the heat shrinkable tube 24.

この熱収縮チューブ２４の内面の接着層が溶けたのみでは、図７のような接着部材１４を電線１１に装着しない場合では、図８に示すように、接着層が溶けてなる接着剤は、液体であっても、隣り合う電線１１間の狭い空間には、電線１１間の径や接着剤の粘性との関係により十分に浸透せず、熱収縮チューブ２４の後端の開口から接着剤が浸透しない電線１１間を通って電線１１と端子１６との接続部分に水が浸入することが懸念される。   In the case where the adhesive member 14 as shown in FIG. 7 is not attached to the electric wire 11 only when the adhesive layer on the inner surface of the heat shrinkable tube 24 is melted, as shown in FIG. Even if it is liquid, it does not sufficiently penetrate into the narrow space between the adjacent electric wires 11 due to the relationship between the diameter between the electric wires 11 and the viscosity of the adhesive, and the adhesive is not supplied from the opening at the rear end of the heat shrinkable tube 24. There is a concern that water may enter the connection portion between the electric wire 11 and the terminal 16 through the electric wire 11 that does not penetrate.

一方、本実施形態のように、接着部材１４が隣り合う電線１１間に配されていれば（図５）、図６に示すように、接着部材１４が溶けて隣り合う電線１１間に浸透し、隣り合う電線１１間の防水性を向上させることが可能となる。なお、図６では、熱収縮チューブ２４の内層２４Ｂの接着剤と接着部材１４が共に溶けて電線１１と熱収縮チューブ２４との間に配された状態を概略的に示している。   On the other hand, if the adhesive member 14 is arranged between the adjacent electric wires 11 as in the present embodiment (FIG. 5), the adhesive member 14 melts and penetrates between the adjacent electric wires 11 as shown in FIG. It becomes possible to improve the waterproofness between the adjacent electric wires 11. FIG. 6 schematically shows a state in which the adhesive of the inner layer 24 </ b> B of the heat shrinkable tube 24 and the adhesive member 14 are melted and arranged between the electric wire 11 and the heat shrinkable tube 24.

If it does in this way, it will become possible to melt | dissolve the adhesive member 14 with the heat | fever at the time of heat-shrinking the heat-shrinkable tube 24, and to infiltrate between the electric wires 11.

（５）導体部１２は、アルミニウム又はアルミニウム合金からなり、端子１６は、銅又は銅合金からなる。
このような電線１１間から水が浸入すると異種金属間の接合部分に電食が発生しやすい構成において、接着部材１４により水の浸入を防止できるため、電食の発生を防止することが可能になる。 (5) The conductor portion 12 is made of aluminum or an aluminum alloy, and the terminal 16 is made of copper or a copper alloy.
In such a configuration that when the water intrudes from between the electric wires 11, the electric corrosion is likely to occur at the joint portion between different metals, the adhesive member 14 can prevent the ingress of water, and therefore it is possible to prevent the occurrence of electric corrosion.
