Description

本発明は、コネクタ付き電線に関する。   The present invention relates to an electric wire with a connector.

従来から、電線と、電線の端末に設けられた端子（圧着端子）をキャビティ（収容室）に収容して保持したコネクタと、を備えたコネクタ付き電線が、自動車用のワイヤハーネス等に用いられている。この種のコネクタ付き電線について、近年、アルミニウムを導体として採用した電線（アルミニウム電線）を用いることが提案されている。アルミニウム電線を用いたコネクタ付き電線は、導体として銅が用いられる場合に比べて軽量かつ低コストであるものの、端子に用いられる材料（一般に、銅）とアルミニウムとの自然電位の差に起因し、端子と導体との接触部分に液体が付着したときに導体の腐食（いわゆるガルバニック腐食）が生じる場合がある。   2. Description of the Related Art Conventionally, an electric wire with a connector including an electric wire and a connector that accommodates and holds a terminal (crimp terminal) provided at the end of the electric wire in a cavity (accommodating chamber) has been used for an automobile wire harness or the like. ing. In recent years, it has been proposed to use an electric wire (aluminum electric wire) that employs aluminum as a conductor for this type of electric wire with a connector. The electric wire with a connector using an aluminum electric wire is lighter and less expensive than the case where copper is used as a conductor, but due to the difference in natural potential between the material used for the terminal (generally copper) and aluminum, When liquid adheres to the contact portion between the terminal and the conductor, the conductor may be corroded (so-called galvanic corrosion).

特に、被水環境下（例えば、自動車のエンジンルーム内）で使用するコネクタ付き電線については、高度な防水性が求められるため、高コストではあるものの、防水用に専用設計されたコネクタ付き電線（いわゆる防水コネクタ）が用いられることが多い。一方、コネクタ付き電線が使用される環境によっては（例えば、自動車の床下内およびドア内に用いられる場合）、防水コネクタほどの高度な防水性が求められない場合がある。そのような場合、コスト削減の観点から、簡易的な防水機能を付加した通常のコネクタ付き電線（いわゆる非防水コネクタ）が用いられることがある。   In particular, for cables with connectors for use in wet environments (for example, in the engine room of automobiles), high waterproofness is required. A so-called waterproof connector is often used. On the other hand, depending on the environment in which the electric wire with the connector is used (for example, when used in an under-floor and a door of an automobile), the waterproof property as high as the waterproof connector may not be required. In such a case, an ordinary electric wire with a connector (so-called non-waterproof connector) to which a simple waterproof function is added may be used from the viewpoint of cost reduction.

例えば、従来のコネクタ付き電線の一つ（以下「従来例」という。）は、コネクタの収容室を保護する筒状のカバー部材を備え、そのカバー部材の一端（拡径部）をコネクタの外周面の全体に被せると共に、そのカバー部材の他端（縮径部）をテープによって電線に固定するようになっている。これにより、従来例は、コネクタの収容室を保護し、簡易的な防水機能をコネクタ付き電線に付加するようになっている（例えば、特許文献１を参照。）。   For example, one of the conventional electric wires with a connector (hereinafter referred to as “conventional example”) includes a cylindrical cover member that protects the housing of the connector, and one end (expanded diameter portion) of the cover member is connected to the outer periphery of the connector. The entire surface is covered, and the other end (reduced diameter portion) of the cover member is fixed to the electric wire with a tape. Thereby, the conventional example protects the housing chamber of the connector and adds a simple waterproof function to the electric wire with the connector (see, for example, Patent Document 1).

特開２００２−１０１５２０号公報JP 2002-101520 A

従来例のカバー部材は、コネクタの外周面の全周を覆うようにコネクタに装着するようになっている。そのため、従来例では、カバー部材を高い寸法精度にて製造する必要があることに加え、その寸法精度の高さに起因してカバー部材をコネクタに取り付ける作業が煩雑となる。その結果、従来例では、コネクタ付き電線の製造効率を十分に高められない可能性がある。   The cover member of the conventional example is attached to the connector so as to cover the entire outer periphery of the connector. Therefore, in the conventional example, in addition to the need to manufacture the cover member with high dimensional accuracy, the work of attaching the cover member to the connector becomes complicated due to the high dimensional accuracy. As a result, in the conventional example, there is a possibility that the manufacturing efficiency of the electric wire with connector cannot be sufficiently increased.

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、簡易防水を実現しつつ、出来る限り容易に製造可能なコネクタ付き電線を提供することにある。   This invention is made | formed in view of the situation mentioned above, The objective is to provide the electric wire with a connector which can be manufactured as easily as possible, implement | achieving simple waterproofing.

上記（１）の構成のコネクタ付き電線によれば、第１端部を形成する複数の突出片がコネクタの形状に対応して変形（湾曲）可能であるため、コネクタへ保護部材を装着する（例えば、保護部材内にコネクタを押し込む）とき、複数の突出片が適宜変形して第１端部の開口面積が広がる。これにより、コネクタへ保護部材を容易に装着できる。更に、第１端部（突出部）の根元までコネクタを挿入すれば、収容口が設けられたコネクタの端面を保護部材の中間部が覆うこととなる。加えて、第１端部のコネクタへの密着および第２端部の電線への固定により、保護部材のずれを防止できる。したがって、本構成のコネクタ付き電線は、簡易防水を実現しつつ、出来る限り容易に製造可能である。   According to the electric wire with a connector having the configuration (1), the plurality of protruding pieces forming the first end portion can be deformed (curved) in accordance with the shape of the connector, and thus the protective member is attached to the connector ( For example, when the connector is pushed into the protective member), the plurality of projecting pieces are appropriately deformed to increase the opening area of the first end. Thereby, a protection member can be easily attached to the connector. Furthermore, if the connector is inserted to the base of the first end (projection), the intermediate portion of the protective member covers the end surface of the connector provided with the accommodation port. In addition, it is possible to prevent the protective member from being displaced by the close contact of the first end portion with the connector and the fixing of the second end portion to the electric wire. Therefore, the connector-attached electric wire of this configuration can be manufactured as easily as possible while realizing simple waterproofing.

上記（２）の構成のコネクタ付き電線によれば、突出片の少なくとも一つが、保護部材の周方向において収容口群の幅よりも広い幅を有するため、保護部材の外部から見たとき、収容口群が突出片に隠されることになる。即ち、収容口群が、保護部材の外部に直接晒されないことになる。そのため、コネクタ付き電線が水に晒された場合であっても、収容口群に水が直接侵入することが防がれる。その結果、本構成のコネクタ付き電線は、収容口群が突出片に隠されない場合に比べ、高い防水機能を有する。   According to the connector-attached electric wire having the configuration of (2), since at least one of the projecting pieces has a width wider than the width of the accommodation port group in the circumferential direction of the protection member, it is accommodated when viewed from the outside of the protection member. The mouth group is hidden by the protruding piece. That is, the storage port group is not directly exposed to the outside of the protective member. Therefore, even if the electric wire with connector is exposed to water, it is possible to prevent water from directly entering the storage port group. As a result, the connector-attached electric wire of this configuration has a high waterproof function as compared with the case where the housing port group is not hidden by the protruding piece.

上記（３）の構成のコネクタ付き電線によれば、突出片がロックアームの可動範囲外に配置されるため、コネクタがロックアームを有する場合であっても、ロックアームの動きが妨げられない。その結果、本構成のコネクタ付き電線は、ロックアームの機能を損なうことなく、簡易防水を実現できる。   According to the electric wire with a connector configured as described in (3) above, since the protruding piece is disposed outside the movable range of the lock arm, the movement of the lock arm is not hindered even when the connector has the lock arm. As a result, the electric wire with connector of this configuration can realize simple waterproofing without impairing the function of the lock arm.

上記（４）の構成のコネクタ付き電線によれば、中間部の内部を通る電線を徐々に収束させられる。更に、テープによる第２端部と電線との固定を容易に行うことができる。その結果、本構成のコネクタ付き電線は、コネクタ付き電線の製造効率を高められる。   According to the connector-attached electric wire having the configuration (4), the electric wire passing through the inside of the intermediate portion can be gradually converged. Further, the second end portion and the electric wire can be easily fixed with the tape. As a result, the electric wire with connector of this configuration can improve the manufacturing efficiency of the electric wire with connector.

上記（５）の構成のコネクタ付き電線によれば、コネクタに対する保護部材のずれを防止できる。その結果、本構成のコネクタ付き電線は、防水機能をより確実に維持できる。   According to the electric wire with a connector having the configuration (5), it is possible to prevent the protective member from being displaced from the connector. As a result, the electric wire with connector of this configuration can more reliably maintain the waterproof function.

本発明によれば、簡易防水を実現しつつ、出来る限り容易に製造可能なコネクタ付き電線を提供できる。   ADVANTAGE OF THE INVENTION According to this invention, the electric wire with a connector which can be manufactured as easily as possible, implement | achieving simple waterproofing can be provided.

Further, the details of the present invention will be further clarified by reading through a mode for carrying out the invention described below (hereinafter referred to as “embodiment”) with reference to the accompanying drawings. .

以下、本発明の実施形態に係るコネクタ付き電線１（以下単に「コネクタ付き電線１」という。）について説明する。   Hereinafter, an electric wire 1 with a connector according to an embodiment of the present invention (hereinafter simply referred to as “electric wire 1 with a connector”) will be described.

＜第１実施形態＞
まず、第１実施形態に係るコネクタ付き電線１について説明する。
図１〜図３に示すように、本実施形態に係るコネクタ付き電線１は、複数本の絶縁電線Ｗａと、コネクタ１０と、保護部材２０と、を備えている。 <First Embodiment>
First, the connector-attached electric wire 1 according to the first embodiment will be described.
As shown in FIGS. 1 to 3, the connector-attached electric wire 1 according to this embodiment includes a plurality of insulated wires Wa, a connector 10, and a protection member 20.

図１において、図中の矢印Ａに示す方向を「前方」と称呼し、矢印Ｂに示す方向を「後方」と称呼し、矢印Ｃに示す方向を「上方」と称呼し、矢印Ｄに示す方向を「下方」と称呼する。   In FIG. 1, the direction indicated by arrow A in the figure is referred to as “front”, the direction indicated by arrow B is referred to as “rear”, the direction indicated by arrow C is referred to as “upward”, and is indicated by arrow D. The direction is referred to as “downward”.

絶縁電線Ｗａは、芯線である導体を絶縁体で被覆したものであり、端末部で絶縁体が剥がされて導体が露出され、露出した導体が圧着端子に圧着接続されている。本例においては、各絶縁電線Ｗａがアルミニウム電線で構成され、圧着端子が銅を主成分とする金属材料で構成されている。つまり、本例においては、絶縁電線Ｗａの導体（芯線）と圧着端子とは異種金属によって構成されている。   The insulated wire Wa is obtained by coating a conductor, which is a core wire, with an insulator. The insulator is peeled off at a terminal portion to expose the conductor, and the exposed conductor is crimped and connected to a crimp terminal. In this example, each insulated wire Wa is made of an aluminum wire, and the crimp terminal is made of a metal material mainly composed of copper. That is, in this example, the conductor (core wire) of the insulated wire Wa and the crimp terminal are made of different metals.

コネクタ１０は、合成樹脂成形品であるコネクタハウジング１１に絶縁電線Ｗａの末端に接続された圧着端子（図示略）を挿入して収容保持したものである。コネクタハウジング１１は、前面から見て上下よりも左右に長い長方形の略ブロック形状をなし、上壁１１ａ、下壁１１ｂ及び左右側壁１１ｃ，１１ｄからなる外周４面と、前方の端面１１ｅと、後方の端面１１ｆとを有している。なお、コネクタハウジング１１は必ずしも上述した形状を有する必要はなく、種々の形状を有するコネクタハウジングが本発明のコネクタ付き電線に用いられ得る。例えば、コネクタハウジングの形状として、前面から見て左右よりも上下に長い長方形の略ブロック形状、前面から見て正方形の略ブロック形状、前面から見て円形または楕円形の形状、及び、外周面が平坦面ではない形状などが挙げられる。   The connector 10 is obtained by inserting and holding a crimp terminal (not shown) connected to the end of the insulated wire Wa into a connector housing 11 which is a synthetic resin molded product. The connector housing 11 has a substantially rectangular block shape that is longer to the left and right than the top and bottom when viewed from the front, and includes four outer peripheral surfaces including an upper wall 11a, a lower wall 11b, and left and right side walls 11c and 11d, a front end surface 11e, and a rear End surface 11f. The connector housing 11 does not necessarily have the shape described above, and connector housings having various shapes can be used for the electric wire with connector of the present invention. For example, as the shape of the connector housing, a rectangular substantially block shape that is vertically longer than the left and right when viewed from the front, a substantially block shape that is square when viewed from the front, a circular or elliptical shape when viewed from the front, and the outer peripheral surface are Examples include shapes that are not flat surfaces.

コネクタハウジング１１は、複数の収容室１３を有している。収容室１３は、左右に配列され、その配列が二段に配置されている。これらの収容室１３は、コネクタハウジング１１の前後方向に沿って形成されており、コネクタハウジング１１の端面１１ｆでの開口部分が収容口１４とされている。絶縁電線Ｗａに接続された圧着端子は、コネクタハウジング１１の端面１１ｆの収容口１４から挿し込まれて収容室１３内に収容保持されている。複数本の絶縁電線Ｗａは、コネクタハウジング１１の収容室１３の収容口１４から後方Ｂへ延びており、コネクタハウジング１１の後方で粘着テープ等によって束ねられて多芯ケーブルＷとされている。なお、コネクタハウジング１１は、必ずしも上述した収容室１３の配置を有する必要はなく、種々の収容室１３の配置を有するコネクタハウジングが本発明のコネクタ付き電線に用いられ得る。   The connector housing 11 has a plurality of storage chambers 13. The storage chambers 13 are arranged on the left and right, and the arrangement is arranged in two stages. These accommodation chambers 13 are formed along the front-rear direction of the connector housing 11, and an opening portion at the end surface 11 f of the connector housing 11 is an accommodation port 14. The crimp terminal connected to the insulated wire Wa is inserted into the housing port 13 of the end surface 11 f of the connector housing 11 and is housed and held in the housing chamber 13. The plurality of insulated wires Wa extend from the accommodation opening 14 of the accommodation chamber 13 of the connector housing 11 to the rear B, and are bundled with an adhesive tape or the like behind the connector housing 11 to form a multicore cable W. In addition, the connector housing 11 does not necessarily need to have the arrangement of the accommodation chamber 13 described above, and connector housings having various arrangements of the accommodation chamber 13 can be used for the electric wire with connector of the present invention.

コネクタハウジング１１は、相手側コネクタのコネクタハウジング（図示省略）に嵌合されることで相手側コネクタのコネクタハウジングと接合される。これにより、コネクタハウジング１１の収容室１３に収容された圧着端子が相手側コネクタのコネクタハウジングに設けられた端子と導通されることになる。   The connector housing 11 is joined to the connector housing of the mating connector by fitting into the connector housing (not shown) of the mating connector. As a result, the crimp terminal accommodated in the accommodation chamber 13 of the connector housing 11 is electrically connected to the terminal provided in the connector housing of the mating connector.

コネクタハウジング１１の上壁１１ａにおける左右幅方向の中央部には、上下方向Ｃ，Ｄ（コネクタハウジング１１の外周面に交差する方向）に変位可能なロックアーム１５が設けられている。ロックアーム１５は、コネクタ１０が相手側コネクタと嵌合する際に、相手側コネクタに設けられたロック部と互いに係合して、両コネクタを係止するためのものである。   A lock arm 15, which can be displaced in the vertical direction C, D (direction intersecting the outer peripheral surface of the connector housing 11), is provided at the center in the left-right width direction of the upper wall 11 a of the connector housing 11. When the connector 10 is fitted to the mating connector, the lock arm 15 engages with a lock portion provided on the mating connector to lock the connectors.

ロックアーム１５は、コネクタハウジング１１の収容口１４が形成された端面１１ｆから離れた位置である先端側でコネクタハウジング１１に連結されている。ロックアーム１５は、コネクタハウジング１１との連結箇所である固定端１５ａからコネクタハウジング１１の後方Ｂへ向かって延在された片持ち梁状に形成されており、その自由端である後端は、コネクタハウジング１１の端面１１ｆの近傍に配置されている。   The lock arm 15 is connected to the connector housing 11 on the distal end side, which is a position away from the end surface 11 f where the accommodation port 14 of the connector housing 11 is formed. The lock arm 15 is formed in a cantilever shape extending from the fixed end 15a, which is a connection point with the connector housing 11, toward the rear B of the connector housing 11, and the rear end, which is a free end, is The connector housing 11 is disposed in the vicinity of the end surface 11f.

ロックアーム１５は、その中間部における上面側に、ロック爪１６が形成されており、このロック爪１６が相手側コネクタのコネクタハウジングに設けられたロック部と係脱される。ロックアーム１５は、その自由端である後端側がコネクタハウジング１１から離間する方向へ湾曲されており、これにより、コネクタハウジング１１の上壁１１ａとの隙間が、コネクタハウジング１１の後方Ｂへ向かって徐々に大きくなっている。ロックアーム１５の後端は、押圧部１７とされており、押圧部１７をコネクタハウジング１１側へ向かって押圧することによってロックアーム１５が弾性変形し、ロック爪１６と相手側コネクタのコネクタハウジングのロック部との係合状態が解除される。即ち、ロックアーム１５は、相手側コネクタのコネクタハウジングに形成された突起および孔部などのロック部と係脱される際に変形して変位する範囲が可動範囲とされている。   The lock arm 15 has a lock claw 16 formed on the upper surface side in the intermediate portion thereof, and the lock claw 16 is engaged with and disengaged from a lock portion provided in the connector housing of the mating connector. The lock arm 15 is curved in a direction in which the rear end side, which is a free end thereof, is separated from the connector housing 11, whereby a gap with the upper wall 11 a of the connector housing 11 is directed toward the rear B of the connector housing 11. It is getting bigger gradually. The rear end of the lock arm 15 is a pressing portion 17. When the pressing portion 17 is pressed toward the connector housing 11, the lock arm 15 is elastically deformed, and the lock claw 16 and the connector housing of the mating connector are connected. The engaged state with the lock portion is released. That is, the range in which the lock arm 15 is deformed and displaced when being engaged with or disengaged from a lock portion such as a protrusion and a hole formed in the connector housing of the mating connector is a movable range.

保護部材２０は、例えば、ゴムやエラストマーなどの弾性を有する柔軟な樹脂材料から形成されており、コネクタハウジング１１の後端側に装着されている。保護部材２０は、第１端部２１と、第２端部２２と、中間部２３とを含む筒形状を有している。   The protection member 20 is formed of, for example, a flexible resin material having elasticity such as rubber or elastomer, and is attached to the rear end side of the connector housing 11. The protection member 20 has a cylindrical shape including a first end portion 21, a second end portion 22, and an intermediate portion 23.

保護部材２０の第１端部２１は、コネクタハウジング１１の外周形状に沿った開口形状に形成されており、第１端部２１には、コネクタハウジング１１の後端が嵌め込まれている。第１端部２１は、中間部２３から突出した複数の突出片２５が中間部２３の周方向に並んだ形状を有している。突出片２５は、コネクタハウジング１１の外周面に密着している。   The first end 21 of the protection member 20 is formed in an opening shape along the outer peripheral shape of the connector housing 11, and the rear end of the connector housing 11 is fitted into the first end 21. The first end portion 21 has a shape in which a plurality of protruding pieces 25 protruding from the intermediate portion 23 are arranged in the circumferential direction of the intermediate portion 23. The protruding piece 25 is in close contact with the outer peripheral surface of the connector housing 11.

図３に示すように、突出片２５は、幅方向の長さ寸法Ｌａを有する一対の突出片２５Ａと、突出片２５Ａよりも小さい長さ寸法Ｌｂを有する一対の突出片２５Ｂとから構成されている。   As shown in FIG. 3, the protruding piece 25 is composed of a pair of protruding pieces 25A having a length dimension La in the width direction and a pair of protruding pieces 25B having a length dimension Lb smaller than the protruding pieces 25A. Yes.

突出片２５Ａは、互いに対向する位置に形成されている。同様に、突出片２５Ｂは、互いに対向位置に形成されている。突出片２５Ａは、コネクタハウジング１１における上壁１１ａ及び下壁１１ｂに密着し、突出片２５Ｂは、コネクタハウジング１１における左右側壁１１ｃ，１１ｄに密着している。   The protruding pieces 25A are formed at positions facing each other. Similarly, the protruding pieces 25B are formed at positions facing each other. The protruding piece 25A is in close contact with the upper wall 11a and the lower wall 11b in the connector housing 11, and the protruding piece 25B is in close contact with the left and right side walls 11c and 11d in the connector housing 11.

突出片２５Ａは、保護部材２０の周方向における幅Ｌａが、コネクタハウジング１１の端面１１ｆにおいて収容口１４が形成する収容口群ＳＡの左右方向の長さ（即ち、保護部材２０の周方向における幅）ＬＡ以上とされ、突出片２５Ｂは、保護部材２０の周方向における幅Ｌｂが、収容口群ＳＡの上下方向の長さ（即ち、保護部材２０の周方向における幅）ＬＢ以上とされている。これにより、保護部材２０の突出片２５の周方向の長さ（２Ｌａ＋２Ｌｂ）は、コネクタハウジング１１の収容口群ＳＡをコネクタハウジング１１の外周面に投影した場合の投影領域の外周面上の長さ（２ＬＡ＋２ＬＢ）以上となっている。   The protruding piece 25A has a width La in the circumferential direction of the protection member 20 that is the length in the left-right direction of the accommodation port group SA formed by the accommodation port 14 on the end surface 11f of the connector housing 11 (that is, the width in the circumferential direction of the protection member 20). ) LA or more, and the protruding piece 25B has a width Lb in the circumferential direction of the protective member 20 that is equal to or greater than the length in the vertical direction of the accommodation port group SA (that is, the width in the circumferential direction of the protective member 20) LB. . Thereby, the circumferential length (2La + 2Lb) of the protruding piece 25 of the protection member 20 is the length on the outer peripheral surface of the projection region when the accommodation port group SA of the connector housing 11 is projected onto the outer peripheral surface of the connector housing 11. It is (2LA + 2LB) or more.

このように、それぞれの突出片２５は、保護部材２０の周方向において、コネクタハウジング１１の収容口群ＳＡの形状に対応した幅を有している。   In this manner, each protruding piece 25 has a width corresponding to the shape of the accommodation port group SA of the connector housing 11 in the circumferential direction of the protection member 20.

更に、コネクタハウジング１１の上壁１１ａに配置される突出片２５は、コネクタハウジング１１の上壁１１ａの表面とロックアーム１５との間の隙間に入り込んでいる。上壁１１ａの表面とロックアーム１５との間の隙間に入り込んだ突出片２５は、ロックアーム１５の可動範囲外に配置されている。よって、突出片２５によってロックアーム１５の可動が妨げられることはない。   Further, the protruding piece 25 disposed on the upper wall 11 a of the connector housing 11 enters a gap between the surface of the upper wall 11 a of the connector housing 11 and the lock arm 15. The protruding piece 25 that has entered the gap between the surface of the upper wall 11 a and the lock arm 15 is disposed outside the movable range of the lock arm 15. Therefore, the movement of the lock arm 15 is not hindered by the protruding piece 25.

保護部材２０の第２端部２２は、複数本の絶縁電線Ｗａの束からなる多芯ケーブルＷの周囲に対応した（ケーブルＷの周囲を覆う）大きさとされている。絶縁電線Ｗａの束からなる多芯ケーブルＷの外周面と第２端部２２との間の隙間は、固定具２８（本例においては、多芯ケーブルＷと第２端部２２とに巻きつけられた粘着テープ）によって塞がれている。固定具２８は、例えば、塩化ビニル及び防水性を有する不織布などのテープ材を第２端部２２の外周と多芯ケーブルＷの外周とにわたって巻き付けることにより、形成されている。これにより、第２端部２２と絶縁電線Ｗａの束からなる多芯ケーブルＷの外周面との隙間が塞がれると共に、保護部材２０と絶縁電線Ｗａとが固定される。なお、固定具２８は、保護部材２０と絶縁電線Ｗａとを固定してそれらの間を塞ぐことができる部材であればよく、必ずしもテープ材に限らない。例えば、他の固定具２８として、樹脂製のキャップ等が用いられ得る。   The second end portion 22 of the protection member 20 has a size corresponding to the periphery of the multi-core cable W composed of a bundle of a plurality of insulated wires Wa (covers the periphery of the cable W). A gap between the outer peripheral surface of the multi-core cable W formed of a bundle of insulated wires Wa and the second end 22 is wound around the fixture 28 (in this example, the multi-core cable W and the second end 22). Is covered with adhesive tape. The fixture 28 is formed by, for example, winding a tape material such as vinyl chloride and waterproof nonwoven fabric around the outer periphery of the second end 22 and the outer periphery of the multicore cable W. Thereby, the gap between the second end portion 22 and the outer peripheral surface of the multi-core cable W formed of a bundle of insulated wires Wa is closed, and the protection member 20 and the insulated wires Wa are fixed. In addition, the fixing tool 28 should just be a member which can fix the protection member 20 and the insulated wire Wa, and can block | close between them, and is not necessarily restricted to a tape material. For example, a resin cap or the like can be used as the other fixture 28.

保護部材２０の中間部２３は、第１端部２１及び第２端部２２の間を構成するもので、第１端部２１及び第２端部２２を繋いでいる。中間部２３は、第１端部２１から第２端部２２へ向かって次第に窄まる形状に形成されている。これにより、中間部２３は、コネクタハウジング１１の端面１１ｆから離れるほど小さい開口断面積を有する形状を有している。   The intermediate portion 23 of the protection member 20 constitutes between the first end portion 21 and the second end portion 22, and connects the first end portion 21 and the second end portion 22. The intermediate portion 23 is formed in a shape that gradually narrows from the first end portion 21 toward the second end portion 22. As a result, the intermediate portion 23 has a shape having an opening cross-sectional area that becomes smaller as the distance from the end surface 11 f of the connector housing 11 increases.

以上、説明したように、第１実施形態に係るコネクタ付き電線１によれば、コネクタハウジング１１へ保護部材２０を装着する際に、第１端部２１（複数の突出片２５）が適宜変形して開口面積が変化するため、コネクタハウジング１１へ保護部材２０を容易に装着できる。   As described above, according to the connector-equipped electric wire 1 according to the first embodiment, when the protective member 20 is attached to the connector housing 11, the first end portion 21 (the plurality of protruding pieces 25) is appropriately deformed. Since the opening area changes, the protective member 20 can be easily attached to the connector housing 11.

更に、第１端部２１（突出部２５）の根元までコネクタハウジング１１を挿入すれば、コネクタハウジング１１の収容口１４がある端面１１ｆを実質的に保護部材２０の中間部２３が覆うこととなる。加えて、第１端部２１のコネクタハウジング１１への密着および第２端部２２の絶縁電線Ｗａへの固定により、保護部材２０のずれが防止される。したがって、コネクタ付き電線１によれば、非防水コネクタに対して簡易防水が可能である。   Furthermore, if the connector housing 11 is inserted to the base of the first end portion 21 (projection portion 25), the intermediate portion 23 of the protection member 20 substantially covers the end surface 11f where the housing port 14 of the connector housing 11 is provided. . In addition, the contact of the first end 21 to the connector housing 11 and the fixing of the second end 22 to the insulated wire Wa prevent the protective member 20 from being displaced. Therefore, according to the electric wire 1 with a connector, simple waterproofing is possible with respect to a non-waterproof connector.

この簡易防水により、銅を主成分とする金属材料からなる圧着端子に対して、異なる材料であるアルミニウムを導体としたアルミニウム電線を用いたとしても、ガルバニック腐食を抑制できる。   With this simple waterproofing, galvanic corrosion can be suppressed even if an aluminum electric wire having a conductor made of aluminum, which is a different material, is used for a crimp terminal made of a metal material mainly composed of copper.

更に、突出片２５が、収容口１４による収容口群ＳＡの形状に対応した幅を保護部材２０の周方向において有することで、保護部材２０による防水機能を高められる。   Furthermore, since the protruding piece 25 has a width corresponding to the shape of the accommodation port group SA by the accommodation port 14 in the circumferential direction of the protection member 20, the waterproof function by the protection member 20 can be enhanced.

更に、突出片２５がロックアーム１５の可動範囲外に配置されるので、コネクタハウジング１１がロックアーム１５を有する場合であっても、突出片２５を有する第１端部２１がロックアーム１５の動きを妨げることはない。つまり、ロックアーム１５の機能を損なうことなく、簡易防水を実現できる。   Further, since the protruding piece 25 is disposed outside the movable range of the lock arm 15, even if the connector housing 11 has the lock arm 15, the first end 21 having the protruding piece 25 is the movement of the lock arm 15. Will not interfere. That is, simple waterproofing can be realized without impairing the function of the lock arm 15.

更に、中間部２３が、コネクタハウジング１１の端面１１ｆから離れるほど開口断面積が小さくなっているので、中間部２３の内部を通る絶縁電線Ｗａを徐々に収束させられる。加えて、固定具２８による第２端部２２と絶縁電線Ｗａとの固定を容易に行うことができ、コネクタ付き電線１の製造が容易になる。   Furthermore, since the opening cross-sectional area becomes smaller as the intermediate portion 23 moves away from the end surface 11f of the connector housing 11, the insulated wire Wa passing through the inside of the intermediate portion 23 can be gradually converged. In addition, the second end 22 and the insulated wire Wa can be easily fixed by the fixture 28, and the manufacture of the connector-equipped wire 1 is facilitated.

＜第２実施形態＞
次に、第２実施形態に係るコネクタ付き電線１について説明する。
なお、上記第１実施形態に係るコネクタ付き電線１と同一構成部分は、同一符号を付して説明を省略する。 Second Embodiment
Next, the electric wire 1 with a connector according to the second embodiment will be described.
In addition, the same components as the connector-equipped electric wire 1 according to the first embodiment are given the same reference numerals, and description thereof is omitted.

図４に示すように、第２実施形態では、保護部材２０の第１端部２１における内周側に、周方向に沿う凹部３１が形成されている。更に、第１端部２１には、凹部３１よりも先端側に、径方向内側へ突出する断面山型形状の係止突起３２が形成されている。一方、コネクタハウジング１１には、端面１１ｆに対応する縁部に、周方向に沿う凸部３５が形成されている。そして、コネクタハウジング１１に形成された凸部３５が、保護部材２０の第１端部２１に形成された凹部３１に係合することにより、コネクタハウジング１１に保護部材２０が係止される。更に、保護部材２０の係止突起３２は、コネクタハウジング１１の凸部３５を係止している。   As shown in FIG. 4, in the second embodiment, a recess 31 is formed along the circumferential direction on the inner peripheral side of the first end 21 of the protection member 20. Furthermore, a locking projection 32 having a mountain-shaped cross section that protrudes radially inward is formed on the first end portion 21 on the tip side of the recess 31. On the other hand, the connector housing 11 is formed with a convex portion 35 along the circumferential direction at the edge corresponding to the end surface 11f. Then, the convex portion 35 formed on the connector housing 11 engages with the concave portion 31 formed on the first end portion 21 of the protective member 20, whereby the protective member 20 is locked to the connector housing 11. Further, the locking protrusion 32 of the protection member 20 locks the convex portion 35 of the connector housing 11.

このように、この第２実施形態に係るコネクタ付き電線１によれば、保護部材２０の凹部３１とコネクタハウジング１１の凸部３５とが係合することで、コネクタハウジング１１に対する保護部材２０のずれを防止し、保護部材２０による確実な簡易防水の効果をより確実に維持できる。   As described above, according to the electric wire with connector 1 according to the second embodiment, the concave portion 31 of the protective member 20 and the convex portion 35 of the connector housing 11 are engaged, so that the protective member 20 is displaced with respect to the connector housing 11. And the effect of reliable simple waterproofing by the protective member 20 can be more reliably maintained.

なお、上記の例では、保護部材２０の凹部３１に、コネクタハウジング１１の凸部３５を係合させたが、保護部材２０側に凸部を形成し、この凸部をコネクタハウジング１１側に形成した凹部に係合させることにより、コネクタハウジング１１に保護部材２０を係止させる構造としても良い。   In the above example, the convex portion 35 of the connector housing 11 is engaged with the concave portion 31 of the protective member 20, but the convex portion is formed on the protective member 20 side, and this convex portion is formed on the connector housing 11 side. The protective member 20 may be locked to the connector housing 11 by engaging with the recessed portion.

また、本発明は上記実施形態に限定されることはなく、本発明の範囲内において種々の変形例を採用できる。   Further, the present invention is not limited to the above embodiment, and various modifications can be adopted within the scope of the present invention.

例えば、図５に示すように、保護部材２０の内側に、径方向内側へ突出する位置決め片４１を形成しても良い。これにより、コネクタハウジング１１に対して保護部材２０の第１端部２１を被せるように組み付ける際に、位置決め片４１がコネクタハウジング１１の端面１１ｆに当接する。よって、コネクタハウジング１１に対する保護部材２０の装着位置を所定の位置に位置決めできる。   For example, as shown in FIG. 5, a positioning piece 41 that protrudes radially inward may be formed inside the protective member 20. Thereby, when assembling the connector housing 11 so as to cover the first end portion 21 of the protection member 20, the positioning piece 41 contacts the end surface 11 f of the connector housing 11. Therefore, the mounting position of the protection member 20 with respect to the connector housing 11 can be positioned at a predetermined position.

なお、本発明は、上述した実施形態に限定されるものではなく、適宜、変形、改良、等が可能である。その他、上述した実施形態における各構成要素の材質、形状、寸法、数、配置箇所、等は本発明を達成できるものであれば任意であり、限定されない。   In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
