- the shielded electric wire includes a core wire 2 (electric wire in which the core wire 2 a is covered with an insulating coating 2 b) serving as a plurality of signal wires, and a metal that covers the outer periphery of the core wire 2 in a converged state. It comprises a shield layer 3 made of a woven wire tube or a metal foil tape wound around the outer periphery, and an outer resin sheath 4 (sheath) 4 provided on the outer periphery of the shield layer 3. And, as shown in FIG.
- the ground connection of the shield layer 3 of the shielded electric wire 1 is covered with the metal braided wire, so that the metal braid drawn from the tip is turned into the drain wire 5, Further, in the shield layer 3 around which the metal foil tape is wound, a core wire in contact with the metal foil tape is arranged and a drain wire which is wired in parallel with the core wire 2 is provided.
- the wire harness including the shielded electric wire is also routed in a wet area such as in an engine room of an automobile.
- a waterproof connector is used to connect the wire and the device or the wires to prevent water from entering the connector.
- the shielded wire has a metal shield layer inside, It is necessary to prevent the shield layer from being corroded by preventing water from entering. That is, in the shielded electric wire 1, as shown in FIG. 6, the outer skin 4 and the shield layer 3 are cut at a cutting position P ⁇ b> 1 with a required dimension from the tip and peeled to expose the core wire 2.
- the core wire 2a is exposed by cutting at a position spaced from the tip by a required dimension, and the terminal 6 is connected to the core wire 2a.

Cover the cap 8 and cover one side of the cap 8 with the outer skin 4, and cover the other side with the core wire 2 protruding from the cutting position P1 and the lead-out end side of the drain wire 5 for waterproofing. Part 100 is provided. Further, as shown in FIGS. 8A and 8B, a required section of the core wire 2 drawn from the cutting position P1 is filled with a water-stopper 7 and cured, and the drawn drain wire 5 is attached to the outer skin 4.
- the tape T is wound after being bent to the outer peripheral surface, and then the heat shrink tube 9 is put on the outer peripheral surface of the outer skin 4 from the filling position of the water-stopping agent 7 across the cutting position P1, and the outer peripheral surface of the filling portion is subjected to heat shrink treatment.
- the waterproof processing unit 20 is provided in close contact with the outer peripheral surface of the outer skin 4.
- the waterproof portion is hardened because the water-stopping agent 7 is cured, and the outer diameter of the electric wire is increased.
- the number of shielded wires in the wire group constituting one wire harness W / H is increasing, and the distance from the connector connecting portion of the wire harness terminal to the waterproof treatment portion is the same for all shielded wires. Therefore, as shown in FIG. 9, the waterproof processing unit 20 for all shielded wires is concentrated at a position close to the connector connection position of the terminal of the wire harness W / H. It becomes difficult to bend and the outer diameter of the wire harness W / H is enlarged.
- the concentrated waterproofing processing unit 50 When it is necessary to bend the concentrated waterproofing processing unit 50 according to the wiring specifications of the wire harness W / H, the concentrated waterproofing processing unit 50 is difficult to bend, so that a situation occurs in which the routing becomes impossible due to a large curvature. Moreover, since the outer diameter of the centralized waterproofing processing unit 50 is enlarged, there arises a problem that the wire harness W / H cannot be accommodated in the corrugated tube 30 of the exterior material.
- the corrugated tube can be accommodated if the size of the corrugated tube is a large size, but the corrugated tube having a large size takes up space on the routing route, and the corrugated tube size other than the central waterproofing processing unit 50 of the wire harness is There is a problem that the slit 30a provided in the axial direction of the corrugated tube 30 is easily opened with respect to the outer diameter of the wire harness. Further, the waterproof treatment at the terminal connection portion of the shielded wire terminal may be applied to other general wires other than the shielded wire routed in the wet area, and the waterproof treatment portion of the general wire is also in the same place. When concentrated, there is a problem that the wire harness is difficult to bend and the outer diameter is enlarged.
- the present invention intends to solve the above-mentioned problem, and eliminates the centralized waterproofing processing unit where the waterproofing processing unit concentrates at the same location, so that the wire harness does not have a place that becomes difficult to bend, and the wire harness conforms to the specification conditions. It is an object of the present invention to make it possible to route the corrugated tube so that the outer diameter of the wire harness is not partially enlarged and accommodated in the corrugated tube as an exterior material. .
- the present invention divides a plurality of shielded wires provided with a waterproofing processing unit in a group of wires constituting one wire harness into a plurality of groups, and the position of the waterproofing processing unit is different for each group.
- the wire harness waterproof structure is characterized in that the wire harness is distributed and arranged in the axial direction of the wire harness with a predetermined interval between the waterproof processing portions of other groups.
- the predetermined interval of the waterproof processing part is at least 50 mm or more.
- the waterproof treatment part provided in each shielded electric wire fills the cut end surface between the shield layer surrounding the plurality of core wires of the shielded electric wire and the outer skin surrounding the shield layer with the water-stopping agent, and from the outer skin sandwiching the cut end surface A heat-shrinkable tube is put on the outer periphery of the filling portion of the water-stopping agent.
- the waterproofing agent filled in the waterproofing unit is made of hot melt or the like and hardens when the required time elapses after filling so that the shielded electric wire is not easily bent.
- the wire harness can be bent more easily than when concentrated in one place, and the outer diameter of the entire wire harness can be reduced, and the exterior material Therefore, it is not necessary to increase the size of the corrugated tube. And since the area
- the distance between the groups is preferably 50 to 80 mm, and the number of groups is preferably two.
- the maximum number of shielded electric wires provided with waterproofing sections in one group is 4-6. For example, when there are eight shielded wires in one wire harness, the number of shield wires in one group is divided into four.
- the plurality of shielded electric wires in one group are provided with the position of the waterproofing processing part opened in accordance with the length of the waterproofing processing part. Specifically, it is preferable that the plurality of shielded electric wires in the one group are shifted by about 10 mm corresponding to the length of the waterproof treatment portion on the side where the waterproofing agent is hardened. However, if the number of shielded wires is large and the peel length from the outer skin and the tip of the shield layer exceeds the set value, two types of shielded wires are provided in each group with the position of the waterproof portion shifted by 10 mm. It is preferable to dispose the staggered waterproofing portions in the radial direction.
- a waterproofing agent when applying a waterproofing agent to the cut end of the insulation coating on a general electric wire other than a shielded electric wire, it is divided into a group together with the shielded electric wire and spaced between the groups and waterproofed within the group. It is preferable to shift the position of the processing unit.
- the waterproofing treatment part of the plurality of shielded wires constituting the wire harness is not concentrated in one place, but dispersed in the axial direction of the wire harness, so that the waterproofing agent is cured and bent in the waterproofing treatment part. Even if it becomes difficult, the fall of the flexibility as the whole wire harness can be suppressed by distributing the waterproofing part which became difficult to bend, and a wire harness can be wired according to specification conditions. In addition, it is necessary to increase the size of the corrugated tube when the wire harness is passed through the corrugated tube without partially increasing the outer diameter of the entire wire harness by dispersing the waterproof treatment part with an enlarged outer diameter. There is no.

Abstract
Description
よって、シールド電線1の端末の切断端からの浸水を防止するため、従来から防水処理が施されている。
また、図8(A)(B)に示すように、切断位置P1から引き出したコア線2の所要区間に止水剤7を充填して硬化させ、かつ、引き出したドレン線5を外皮4の外周面に折り曲げた後にテープTを巻き付け、その後、切断位置P1を跨いで止水剤7の充填箇所から外皮4の外周面にかけて熱収縮チューブ9を被せ、熱収縮処理して充填箇所の外周面に密着させると共に外皮4の外周面に密着させて、防水処理部20を設けている。
1つのワイヤハーネスW/Hを構成する電線群中のシールド電線の本数が増加しており、ワイヤハーネス端末のコネクタ接続部から防水処理部までの距離は全シールド電線で同一である。よって、図9に示すように、ワイヤハーネスW/Hの端末のコネクタ接続位置に近接する位置に全シールド電線の防水処理部20が集中することになり、該集中防水処理部50ではワイヤハーネスが曲がり難くなると共に、ワイヤハーネスW/Hの外径が肥大化する。
さらに、前記シールド電線端末の端子接続部における防水処理は、被水領域に配索するシールド電線以外の他の一般電線に対しても施す場合があり、該一般電線の防水処理部も同一箇所に集中するとワイヤハーネスが曲げにくくなると共に外径が肥大化する問題がある。
なお、防水処理部は充填した止水剤は、ホットメルト等からなり、充填後所要時間経過すると硬化してシールド電線が曲がりにくくなるものである。
1つのグループ内における防水処理部を設けるシールド電線の最大本数は4~6本としている。例えば、1つのワイヤハーネス中に8本のシールド電線がある場合には、1つのグループのシールド電線の本数は4本づつとして分けている。
しかしながら、シールド電線の本数が多く、外皮およびシールド層の先端からの剥離長さが設定値を越える場合には、1グループ内に防水処理部の位置を10mmずらせたシールド電線を2種類設け、10mmずらせた防水処理部を径方向に千鳥配置することが好ましい。
図1に示すワイヤハーネス10は、自動車のエンジンルーム内に配索するものであり、該エンジンルーム内は被水領域である。該ワイヤハーネス10を構成する電線群中にはシールド電線11が複数本(本実施形態では8本)含まれており、かつ、シールド電線11以外の電線12も含まれている。該ワイヤハーネス10の一端には、前記8本のシールド電線11の端末に防水コネクタ14を接続し、エンジンルーム内に搭載したECU(電子制御ユニット)15のコネクタ嵌合部15aに接続している。シールド電線11以外の一般電線12には他の防水コネクタ(図示せず)を接続している。即ち、ワイヤハーネス10の一端側では8本のシールド電線11を収束した枝線10A、他の電線群の枝線10Bとが分岐している。
前記引き出した各コア線2も先端P2から所要寸法離れた切断位置P3で絶縁被覆2bを切断して芯線2aを露出させている。この露出させた芯線2aおよび切断位置P3に隣接する絶縁被覆2bにそれぞれ端子6のバレル6a、6bを加締め圧着して接続している。かつ、前記外皮4の切断位置P1に沿った外周面にテープTを巻き付けている。
該防水処理部20の熱収縮チューブ9を被せた部分の長さは約20mmであり、該防水処理部20の止水剤充填側20aの長さは約10mmであり、該止水剤充填側20aが曲がりにくくなると共に外径が増大する部分である。
即ち、シールド電線11aの切断位置P1は先端から90mmの位置、シールド電線11bの切断位置P1は先端から100mmの位置としている。
同様に、シールド電線11c、11d、11eの切断位置P1を順次10mm間隔をあけて位置させて設け、シールド電線11eの切断位置P1は先端から130mmの位置としている。
このように、第1グループG1の5本のシールド電線11a~11eの防水処理部の止水剤充填側20aの先端位置を10mmづつあけて位置させ、止水剤充填側20aが径方向でかさならないようにしている。
また、径方向に防水処理部20の止水剤充填側20aを重ねていないため、枝線10Aの局部的な外径の肥大化を防止できる。よって、該枝線10Aにコルゲートチューブ30を被せて枝線10Aを保護する場合、コルゲートチューブ30のサイズを大きくする必要はなく、枝線の配索箇所にスペースをとらない。
この場合、防水処理部20の全体長さ分だけ位置ずれさせており、シールド電線11a~11cを第1グループG1、シールド電線11d~11fを第2グループG2としてグループ分けしている。第1グループG1ではシールド電線の防水処理部20の間隔を20mmずらせ、第2グループG2で同様としている。また、第1グループG1と第2グループG2の間隔も80mmずらせている。
