Description

本発明は、ワイヤハーネスに関する。 The present invention relates to a wire harness.

従来、ワイヤハーネスにおいては、電線の端末にコネクタを組み付けたコネクタ付き電線として構成されたものが知られている。そのコネクタにおいては、端子金具がハウジングの中で電線の端末に電気接続され、かつ、その電線がハウジングの外に引き出されている。ワイヤハーネスにおいては、このコネクタを端子台又は相手方コネクタに嵌合接続させ、これに伴い、端子金具を端子台等の相手方端子金具に嵌合接続させたり、端子金具を相手方端子金具に螺子止め固定させたりする。この種のワイヤハーネスについては、例えば、下記の特許文献１から３に開示されている。 Conventionally, in a wire harness, it is known that the wire harness is configured as an electric wire with a connector in which a connector is assembled to the end of the electric wire. In the connector, the terminal fitting is electrically connected to the end of the electric wire in the housing, and the electric wire is pulled out of the housing. In a wire harness, this connector is fitted and connected to the terminal block or the mating connector, and accordingly, the terminal fitting is fitted and connected to the mating terminal fitting such as the terminal block, or the terminal fitting is screwed and fixed to the mating terminal fitting. Let me do it. This type of wire harness is disclosed in, for example, Patent Documents 1 to 3 below.

特開２０１４－１０７１５２号公報Japanese Unexamined Patent Publication No. 2014-107152 特開２０１６－１９２３５９号公報Japanese Unexamined Patent Publication No. 2016-192359 特開２０１８－４１５５４号公報Japanese Unexamined Patent Publication No. 2018-41554

ところで、ワイヤハーネスにおいては、自動車等の車両に搭載された場合、端子台等が車体側の電気機器等に設けられているので、走行時の路面入力や加減速によってコネクタからの電線の引出部分に力が加えられると、その力に伴う電線の振れが振動として端子金具側に伝播されてしまう可能性がある。そして、このワイヤハーネスにおいては、その電線の振れに伴う振動が端子金具に伝わってしまうと、嵌合接続状態の端子金具と相手方端子金具との間の接点における接触圧力が変化し、その相互間での通電性能にばらつきを生じさせてしまう虞がある。また、このワイヤハーネスにおいては、電線の振れに伴う振動が端子金具に伝わってしまうと、螺子止め固定状態の端子金具と相手方端子金具とに過荷重が加えられてしまう虞がある。 By the way, in a wire harness, when it is mounted on a vehicle such as an automobile, a terminal block or the like is provided on an electric device or the like on the vehicle body side. When a force is applied to the wire, the runout of the electric wire due to the force may be propagated to the terminal metal fitting side as vibration. Then, in this wire harness, when the vibration accompanying the runout of the electric wire is transmitted to the terminal fitting, the contact pressure at the contact point between the terminal fitting in the mated connection state and the mating terminal fitting changes, and the contact pressure between them changes. There is a risk of causing variations in the energization performance in. Further, in this wire harness, if the vibration caused by the runout of the electric wire is transmitted to the terminal fitting, there is a possibility that an overload is applied to the terminal fitting in the screw-fixed state and the other terminal fitting.

そこで、本発明は、電線から端子金具への振動伝播を抑止し得るワイヤハーネスを提供することを、その目的とする。 Therefore, an object of the present invention is to provide a wire harness capable of suppressing vibration propagation from an electric wire to a terminal fitting.

上記目的を達成する為、本発明は、電線と、前記電線の端末に組み付けられたコネクタと、を備え、前記コネクタは、前記電線の前記端末に対して直接的又は間接的に電気接続された端子金具と、前記電線及び前記端子金具を内方の収容室に収容させつつ、前記電線を前記収容室の引出口から外方に引き出させる絶縁性のハウジングと、前記収容室の内周壁と前記電線との間の隙間を埋めるシール部材と、前記収容室で前記電線を保持する電線保持具と、を備え、前記ハウジングは、前記電線保持具を保持する保持部を有することを特徴としている。 In order to achieve the above object, the present invention includes an electric wire and a connector attached to the terminal of the electric wire, and the connector is directly or indirectly electrically connected to the terminal of the electric wire. The terminal fittings, the electric wire and the insulating housing that allows the electric wire and the terminal fitting to be pulled out from the outlet of the accommodation chamber while being accommodated in the inner accommodation chamber, the inner peripheral wall of the accommodation chamber, and the said. The housing includes a sealing member that fills a gap between the electric wires and an electric wire holder that holds the electric wires in the accommodation chamber, and the housing has a holding portion that holds the electric wire holders.

本発明に係るワイヤハーネスは、車両走行時に電線の引出部分で発生した振れがコネクタに振動として伝わってきたとしても、その振動の端子金具への伝播を電線保持具と保持部で抑止することができる。 In the wire harness according to the present invention, even if the vibration generated at the lead-out portion of the electric wire is transmitted to the connector as vibration when the vehicle is running, the propagation of the vibration to the terminal fitting can be suppressed by the electric wire holder and the holding portion. can.

以下に、本発明に係るワイヤハーネスの実施形態を図面に基づいて詳細に説明する。尚、この実施形態によりこの発明が限定されるものではない。 Hereinafter, embodiments of the wire harness according to the present invention will be described in detail with reference to the drawings. The present invention is not limited to this embodiment.

［実施形態］
本発明に係るワイヤハーネスの実施形態の１つを図１から図１２に基づいて説明する。 [Embodiment]
One of the embodiments of the wire harness according to the present invention will be described with reference to FIGS. 1 to 12.

図１から図４の符号ＷＨは、本実施形態ワイヤハーネスを示す。このワイヤハーネスＷＨは、所謂コネクタ付き電線であり、電線Ｗｅと、この電線Ｗｅの端末に組み付けられたコネクタ１と、を備える。ここで示すワイヤハーネスＷＨは、極数の数が複数のコネクタ１を備えるものであり、その極数の数に応じた本数の電線Ｗｅが具備されている。この例示では、このワイヤハーネスＷＨが２本の電線Ｗｅと２極のコネクタ１を備えている。 Reference numerals WH of FIGS. 1 to 4 indicate the wire harness of the present embodiment. The wire harness WH is a so-called electric wire with a connector, and includes an electric wire We and a connector 1 assembled to a terminal of the electric wire We. The wire harness WH shown here includes a connector 1 having a plurality of poles, and is provided with a number of electric wires We corresponding to the number of poles. In this example, the wire harness WH includes two wires We and a two-pole connector 1.

コネクタ１は、相手方嵌合部（図示略）に対して先端から挿入嵌合させることによって、相手方端子金具（図示略）に電気接続させる。例えば、ここで示すコネクタ１は、内周壁面を有する孔状の相手方嵌合部の内方に後述するハウジング２０の嵌合部２０ａを挿入嵌合させるものとして構成されている。このコネクタ１は、その孔状の相手方嵌合部に対して、この相手方嵌合部の孔軸方向に沿って嵌合部２０ａを挿抜させる。相手方嵌合部は、例えば、孔軸方向に対する直交断面が矩形を成すものとして形成されている。尚、相手方嵌合部は、筒状に形成され、その内方の空間に嵌合部２０ａを挿入嵌合させるものであってもよい。 The connector 1 is electrically connected to the mating terminal fitting (not shown) by inserting and fitting the connector 1 into the mating portion (not shown) from the tip. For example, the connector 1 shown here is configured to insert and fit the fitting portion 20a of the housing 20, which will be described later, inside the hole-shaped mating fitting portion having the inner peripheral wall surface. The connector 1 inserts and removes the fitting portion 20a from the hole-shaped mating portion along the hole axis direction of the mating portion. The mating portion is formed, for example, so that the cross section orthogonal to the hole axis direction forms a rectangle. The mating portion may be formed in a cylindrical shape, and the fitting portion 20a may be inserted and fitted in the space inside the mating portion.

例えば、このコネクタ１は、相手方機器（図示略）の相手方端子金具に電気接続させることによって、この相手方機器と電線Ｗｅの先の機器（図示略）との間を電気接続させる。その相手方機器は、金属製の筐体を備えており、この筐体の壁体に形成された貫通孔を相手方嵌合部として利用する。また、この相手方機器は、その筐体の内部に端子台又は相手方コネクタを備えている。相手方端子金具は、その端子台又は相手方コネクタが備えるものである。よって、コネクタ１は、嵌合部２０ａが相手方嵌合部の内方に挿入嵌合され、筐体の内部で端子台又は相手方コネクタの相手方端子金具に電気接続させる。 For example, the connector 1 is electrically connected to the other party's terminal fitting of the other party's device (not shown) to electrically connect the other party's device and the device at the end of the electric wire We (not shown). The other party's device includes a metal housing, and a through hole formed in the wall of the housing is used as a mating portion for the other party. Further, this counterparty device is provided with a terminal block or a counterparty connector inside the housing. The mating terminal fitting is provided by the terminal block or the mating connector. Therefore, in the connector 1, the fitting portion 20a is inserted and fitted inside the mating portion of the mating portion, and is electrically connected to the terminal block or the mating terminal fitting of the mating connector inside the housing.

以下において、特段の言及も無く単に挿入方向と記した場合、その挿入方向は、相手方嵌合部に対するコネクタ１の嵌合部２０ａの挿入方向のことを示している。また、特段の言及も無く単に抜去方向と記した場合、その抜去方向は、相手方嵌合部に対するコネクタ１の嵌合部２０ａの抜去方向のことを示している。また、特段の言及も無く単に挿抜方向と記した場合、その挿抜方向は、相手方嵌合部に対するコネクタ１の嵌合部２０ａの挿抜方向のことを示している。 In the following, when the insertion direction is simply described without any particular mention, the insertion direction indicates the insertion direction of the fitting portion 20a of the connector 1 with respect to the mating portion of the other party. Further, when the removal direction is simply described without any particular mention, the removal direction indicates the removal direction of the fitting portion 20a of the connector 1 with respect to the mating portion of the other party. Further, when the insertion / removal direction is simply described without any particular mention, the insertion / removal direction indicates the insertion / removal direction of the fitting portion 20a of the connector 1 with respect to the mating portion of the other party.

このコネクタ１は、端子金具１０と、電線Ｗｅ及び端子金具１０を収容させる絶縁性のハウジング２０と、ノイズ低減を図るための導電性のシールドシェル３０と、を備える（図１、図３及び図４）。 The connector 1 includes a terminal fitting 10, an insulating housing 20 for accommodating the electric wire We and the terminal fitting 10, and a conductive shield shell 30 for reducing noise (FIGS. 1, 3, and 3). 4).

端子金具１０は、金属等の導電性材料で成形される。例えば、この端子金具１０は、母材となる金属板に対する折曲げ加工や切断加工等のプレス成形によって所定形状に成形される。 The terminal fitting 10 is formed of a conductive material such as metal. For example, the terminal fitting 10 is formed into a predetermined shape by press forming such as bending or cutting on a metal plate as a base material.

この端子金具１０は、相手方端子金具の相手方端子接続部に対して物理的且つ電気的に接続させる端子接続部１１を有する（図１、図３及び図４）。例えば、端子接続部１１と相手方端子接続部は、嵌合部２０ａと相手方嵌合部の挿入嵌合に伴って、互いに嵌合接続させる。この形態の端子接続部１１と相手方端子接続部は、その内の一方が雌端子形状に形成され、その内の他方が雄端子形状に形成される。また、例えば、端子接続部１１と相手方端子接続部は、互いに螺子止め固定させるものであってもよい。この例示では、端子接続部１１が円筒状の雌端子形状に形成され、かつ、相手方端子接続部が端子接続部１１の内方に嵌入させる軸状の雄端子形状に形成されている。端子金具１０においては、この端子接続部１１の筒軸方向が挿抜方向になる。この例示の端子接続部１１の内方には、弾性変形可能な接点部材（図示略）が組み付けられている。 The terminal fitting 10 has a terminal connecting portion 11 that is physically and electrically connected to the mating terminal connecting portion of the mating terminal fitting (FIGS. 1, 3 and 4). For example, the terminal connection portion 11 and the mating terminal connecting portion are fitted and connected to each other as the fitting portion 20a and the mating fitting portion are inserted and fitted. One of the terminal connection portion 11 and the mating terminal connection portion of this form is formed in the shape of a female terminal, and the other is formed in the shape of a male terminal. Further, for example, the terminal connection portion 11 and the mating terminal connection portion may be fixed to each other by screwing. In this example, the terminal connection portion 11 is formed in a cylindrical female terminal shape, and the mating terminal connection portion is formed in a shaft-shaped male terminal shape to be fitted inside the terminal connection portion 11. In the terminal fitting 10, the tubular axis direction of the terminal connection portion 11 is the insertion / removal direction. An elastically deformable contact member (not shown) is assembled inside the terminal connection portion 11 of this example.

この端子金具１０は、電線Ｗｅの端末に対して直接的又は間接的に電気接続させる。例えば、端子金具１０は、電線Ｗｅの端末に対して物理的且つ電気的に接続させる電線接続部１２を設けておくことによって、電線Ｗｅの端末に対して直接的に電気接続させる（図３及び図４）。また、例えば、端子金具１０は、電線Ｗｅの端末との間に中継端子（図示略）を介在させることによって、電線Ｗｅの端末に対して間接的に電気接続させる。ここで示す端子金具１０は、電線接続部１２を有しており、電線Ｗｅの端末に対して直接的に電気接続させている。 The terminal fitting 10 is directly or indirectly electrically connected to the terminal of the electric wire We. For example, the terminal fitting 10 is directly electrically connected to the terminal of the electric wire We by providing the electric wire connecting portion 12 which is physically and electrically connected to the terminal of the electric wire We (FIG. 3 and FIG. FIG. 4). Further, for example, the terminal fitting 10 is indirectly electrically connected to the terminal of the electric wire We by interposing a relay terminal (not shown) between the terminal and the terminal of the electric wire We. The terminal fitting 10 shown here has an electric wire connecting portion 12, and is directly electrically connected to the terminal of the electric wire We.

電線接続部１２は、電線Ｗｅの端末の剥き出しの芯線に対して、例えば、圧着又は溶着させることによって、この電線Ｗｅに対して物理的且つ電気的に接続させる。ここで示す電線接続部１２は、２枚のバレル片を剥き出しの芯線に加締め圧着させている。電線Ｗｅは、この電線接続部１２から引き出されている。 The electric wire connecting portion 12 is physically and electrically connected to the exposed core wire of the terminal of the electric wire We by, for example, crimping or welding. In the electric wire connecting portion 12 shown here, two barrel pieces are crimped and crimped to the exposed core wire. The electric wire We is drawn out from the electric wire connecting portion 12.

端子金具１０は、端子接続部１１の筒軸方向と電線接続部１２における電線Ｗｅの引出方向とが同じ向きのストレート形状に成形される。このストレート形状の端子金具１０を用いる場合には、電線接続部１２から引き出された電線Ｗｅをそのまま引出方向に延在させてハウジング２０に収容してもよく、電線接続部１２から引き出された電線Ｗｅを途中で折り曲げてハウジング２０に収容してもよい。この例示では、ストレート形状の端子金具１０と、電線接続部１２から引き出された後で９０度折り曲げられた電線Ｗｅと、がハウジング２０に収容されている（図３及び図４）。 The terminal fitting 10 is formed into a straight shape in which the axial direction of the terminal connecting portion 11 and the drawing direction of the electric wire We in the electric wire connecting portion 12 are in the same direction.

ハウジング２０は、この第１電線保持具６０を保持する保持部２０ｇを有する（図３、図５及び図６）。この保持部２０ｇは、ハウジング２０に少なくとも１つ設ける。このコネクタ１においては、第１電線保持具６０で電線Ｗｅを保持し、その第１電線保持具６０をハウジング２０の保持部２０ｇに保持させることによって、車両走行時に電線Ｗｅの引出部分で発生した振れが振動として伝わってきたとしても、その振動の端子金具１０への伝播を第１電線保持具６０と保持部２０ｇで抑止することができる。そして、このコネクタ１においては、この第１電線保持具６０を電線Ｗｅの軸線方向で端子側シール部材４３に並べて配置しているので、第１電線保持具６０と保持部２０ｇによる振動の伝播抑止効果に起因して、収容室２０ｃの中での電線Ｗｅの振れも抑えられる。よって、このコネクタ１においては、電線Ｗｅの振れに伴う端子側シール部材４３の押し潰しを抑止できるので、電線Ｗｅと端子側シール部材４３との間に隙間ができ難くなっており、端子側シール部材４３による防水性能と防塵性能を向上させることができる。 The housing 20 has a holding portion 20 g for holding the first electric wire holder 60 (FIGS. 3, 5 and 6). At least one of the holding portions 20g is provided in the housing 20. In this connector 1, the electric wire We is held by the first electric wire holder 60, and the first electric wire holder 60 is held by the holding portion 20 g of the housing 20, so that the electric wire We is generated at the drawer portion of the electric wire We when the vehicle is running. Even if the vibration is transmitted as vibration, the propagation of the vibration to the terminal fitting 10 can be suppressed by the first electric wire holder 60 and the holding portion 20 g. In this connector 1, since the first electric wire holder 60 is arranged side by side on the terminal side seal member 43 in the axial direction of the electric wire We, the first electric wire holder 60 and the holding portion 20g suppress the propagation of vibration. Due to the effect, the runout of the electric wire We in the accommodation chamber 20c is also suppressed. Therefore, in this connector 1, since it is possible to suppress the crushing of the terminal side seal member 43 due to the runout of the electric wire We, it is difficult to form a gap between the electric wire We and the terminal side seal member 43, and the terminal side seal The waterproof performance and dustproof performance of the member 43 can be improved.

ここで、第１電線保持具６０は、端子側シール部材４３よりも端子金具１０側に配置してもよく、端子側シール部材４３よりも収容室２０ｃの引出口２０ｄ側に配置してもよい。 Here, the first electric wire holder 60 may be arranged closer to the terminal fitting 10 than the terminal side seal member 43, or may be arranged closer to the outlet 20d side of the accommodation chamber 20c than the terminal side seal member 43. ..

このコネクタ１においては、第１電線保持具６０を端子側シール部材４３よりも端子金具１０側に配置している（図３）。これにより、このコネクタ１においては、引出部分から伝わってきた電線Ｗｅの振動が先ず端子側シール部材４３で吸収され、続いて、ここで吸収しきれなかった残りの振動成分の端子金具１０側への伝播が第１電線保持具６０と保持部２０ｇで抑止される。よって、このコネクタ１においては、第１電線保持具６０と保持部２０ｇによって抑え込む振動を端子側シール部材４３で小さくしておくことができるので、振動の端子金具１０への伝播抑止効果を高めることができる。 In this connector 1, the first electric wire holder 60 is arranged closer to the terminal fitting 10 than the terminal-side sealing member 43 (FIG. 3). As a result, in this connector 1, the vibration of the electric wire We transmitted from the lead-out portion is first absorbed by the terminal side sealing member 43, and then to the terminal metal fitting 10 side of the remaining vibration component that could not be completely absorbed here. Is suppressed by the first electric wire holder 60 and the holding portion 20 g. Therefore, in this connector 1, the vibration suppressed by the first electric wire holder 60 and the holding portion 20g can be reduced by the terminal-side sealing member 43, so that the effect of suppressing the propagation of the vibration to the terminal fitting 10 can be enhanced. Can be done.

一方、このコネクタ１においては、第１電線保持具６０を端子側シール部材４３よりも収容室２０ｃの引出口２０ｄ側に配置することによって、引出部分から伝わってきた電線Ｗｅの振動の端子金具１０側への伝播を第１電線保持具６０と保持部２０ｇで抑止しきれなかった場合でも、第１電線保持具６０と保持部２０ｇで小さくなった振動が端子金具１０に伝わる前に、この振動を端子側シール部材４３で吸収することができる。よって、このコネクタ１においては、仮に第１電線保持具６０と保持部２０ｇで振動を抑え込むことができなかったとしても、振動の端子金具１０への伝播を抑止することができる。 On the other hand, in this connector 1, by arranging the first electric wire holder 60 on the outlet 20d side of the accommodation chamber 20c with respect to the terminal side sealing member 43, the terminal metal fitting 10 of the vibration of the electric wire We transmitted from the extraction portion. Even if the first wire holder 60 and the holding portion 20g cannot completely suppress the propagation to the side, this vibration before the vibration reduced by the first wire holder 60 and the holding portion 20g is transmitted to the terminal fitting 10. Can be absorbed by the terminal-side seal member 43. Therefore, in this connector 1, even if the vibration cannot be suppressed by the first electric wire holder 60 and the holding portion 20 g, it is possible to suppress the propagation of the vibration to the terminal fitting 10.

(FIGS. 3, 9 and 10). In the second shield shell member 32, the opening on the inner peripheral surface side of the annular portion 32d is used as the outlet 32c of the electric wire We.

また、この第２シールドシェル部材３２においては、筒部３２ａにおける引出口３２ｃとは逆側の開口の周縁及びその近傍を端部とし、この端部を第１シールドシェル部材３１に面接触させる。 Further, in the second shield shell member 32, the peripheral edge of the opening on the side opposite to the outlet 32c in the tubular portion 32a and its vicinity are set as end portions, and this end portion is brought into surface contact with the first shield shell member 31.

ここで示す第２シールドシェル部材３２には、その筒部３２ａにおける引出口３２ｃとは逆側の開口の周縁に平板状のフランジ部３２ｅが設けられている（図１から図４、図９及び図１０）。このフランジ部３２ｅは、その平面を第１シールドシェル部材３１の主壁３１ａにおける電線Ｗｅの引出方向側の端面に面接触させる。 The second shield shell member 32 shown here is provided with a flat flange portion 32e on the peripheral edge of the opening on the side opposite to the outlet 32c in the tubular portion 32a (FIGS. 1 to 4, 9 and).

ここで、第１シールドシェル部材３１には、その主壁３１ａの端面と同一平面上の壁面を有する２つの固定部３１ｄが側壁３１ｂに設けられている（図１、図２、図９及び図１０）。この固定部３１ｄは、フランジ部３２ｅを介して、第２シールドシェル部材３２を第１シールドシェル部材３１に螺子止め固定させるためのものである。よって、フランジ部３２ｅは、その平面を２つの固定部３１ｄの壁面に面接触させる。ここでは、それぞれの固定部３１ｄに雌螺子部Ｎ２が形成されている（図１０）。そして、フランジ部３２ｅには、雄螺子部材Ｂ２（図１、図２及び図９）を挿通させるための貫通孔３２ｅ１が固定部３１ｄ毎に形成されている（図１０）。第２シールドシェル部材３２は、その貫通孔３２ｅ１に雄螺子部材Ｂ２を挿通させた上で、この雄螺子部材Ｂ２を雌螺子部Ｎ２に螺合させることによって、第１シールドシェル部材３１に螺子止め固定される。 Here, the first shield shell member 31 is provided with two fixing portions 31d having a wall surface on the same plane as the end surface of the main wall 31a on the side wall 31b (FIGS. 1, FIG. 2, FIG. 9 and FIGS. 10). The fixing portion 31d is for screwing and fixing the second shield shell member 32 to the first shield shell member 31 via the flange portion 32e. Therefore, the flange portion 32e brings its flat surface into surface contact with the wall surfaces of the two fixing portions 31d. Here, a female screw portion N2 is formed in each fixing portion 31d (FIG. 10). A through hole 32e 1 for inserting the male screw member B2 (FIGS. 1, 2 and 9) is formed in the flange portion 32e for each fixing portion 31d (FIG. 10). The second shield shell member 32 is screwed into the first shield shell member 31 by inserting the male screw member B2 into the through hole 32e 1 and then screwing the male screw member B2 into the female screw portion N2. It is stopped and fixed.

更に、この第２シールドシェル部材３２には、そのフランジ部３２ｅから電線Ｗｅの引出方向とは逆側に突出させ、かつ、第１シールドシェル部材３１の主壁３１ａに外側から被せて面接触させる平板状の第１片部３２ｆを有する（図２から図４及び図９）。ここでは、この第１片部３２ｆが矩形の平板状に形成されている。そして、第１シールドシェル部材３１の主壁３１ａには、その第１片部３２ｆが入り込む矩形の溝部３１ａ１が形成されている（図２、図３及び図９）。 Further, the second shield shell member 32 is projected from the flange portion 32e in the direction opposite to the drawing direction of the electric wire We, and is put on the main wall 31a of the first shield shell member 31 from the outside to be brought into surface contact. It has a flat plate-shaped first piece portion 32f (FIGS. 2 to 4 and 9). Here, the first piece portion 32f is formed in a rectangular flat plate shape. The main wall 31a of the first shield shell member 31 is formed with a rectangular groove portion 31a 1 into which the first piece portion 32f is inserted (FIGS. 2, 3 and 9).

また更に、この第２シールドシェル部材３２には、第１片部３２ｆとは逆側でフランジ部３２ｅから電線Ｗｅの引出方向とは逆側に突出させ、かつ、ハウジング本体２１に外側から対向配置させた平板状の第２片部３２ｇを有する（図１から図４、図９及び図１０）。 Furthermore, the second shield shell member 32 is projected from the flange portion 32e on the side opposite to the first piece portion 32f and on the side opposite to the drawing direction of the electric wire We, and is arranged to face the housing body 21 from the outside. It has 32 g of a flat plate-shaped second piece (FIGS. 1 to 4, 9 and 10).

このコネクタ１は、網目の筒状に編み上げられ、かつ、この第２シールドシェル部材３２の筒部３２ａに密着状態で被せつつ、電線Ｗｅにおける電線収容室３２ｂから引き出された第２引出部Ｗｅ２を覆う導電性の編組部材３５を備える（図１から図４）。そして、このコネクタ１は、その編組部材３５を筒部３２ａの外周壁との間に挟みこんで加締め圧着させる環状のシールリング３６を備える（図１から図４）。例えば、このコネクタ１は、第１シールドシェル部材３１の側壁３１ｂに設けた２つの固定部３１ｅ（図１、図２、図９及び図１０）を相手方機器の金属製の筐体に螺子止め固定させ、その筐体にシールドシェル３０と編組部材３５を電気接続させることによってノイズを逃がす。 The connector 1 is knitted into a mesh tubular shape, and covers the tubular portion 32a of the second shield shell member 32 in close contact with the second drawer portion We2 drawn from the electric wire accommodating chamber 32b in the electric wire We. A conductive braided member 35 for covering is provided (FIGS. 1 to 4). The connector 1 is provided with an annular seal ring 36 that sandwiches the braided member 35 with the outer peripheral wall of the tubular portion 32a and crimps it by crimping (FIGS. 1 to 4). For example, in this connector 1, two fixing portions 31e (FIGS. 1, FIG. 2, FIG. 9 and FIG. 10) provided on the side wall 31b of the first shield shell member 31 are screwed and fixed to the metal housing of the other device. The noise is released by electrically connecting the shield shell 30 and the braided member 35 to the housing.

更に、このコネクタ１は、筒状に形成され、かつ、第２シールドシェル部材３２の筒部３２ａに密着状態で被せつつ編組部材３５に被せて、この編組部材３５を内方に覆い隠すよう収容させるゴムブーツ７０を備える（図３）。このゴムブーツ７０は、例えば、外側から結束バンド等の締結部材７５を巻き付けて、筒部３２ａの外周壁に密着状態で固定させる。尚、本図以外では、ゴムブーツ７０を省略している。 Further, the connector 1 is formed in a tubular shape, and is housed so as to cover the braided member 35 inward while covering the tubular portion 32a of the second shield shell member 32 in close contact with the braided member 35. A rubber boot 70 is provided (FIG. 3). The rubber boot 70 is, for example, wound with a fastening member 75 such as a binding band from the outside and fixed to the outer peripheral wall of the tubular portion 32a in a close contact state. In addition, the rubber boot 70 is omitted except in this figure.

このコネクタ１においては、このゴムブーツ７０によって、編組部材３５への外側からの水や塵埃の接触を抑止している。一方、このコネクタ１においては、シールドシェル３０が第１シールドシェル部材３１と第２シールドシェル部材３２による分割構造を採っているので、その間の合わせ面や第２シールドシェル部材３２とハウジング本体２１との間の隙間等からシールドシェル３０の中に水や塵埃が入り込んでしまう可能性がある。その合わせ面とは、第１シールドシェル部材３１の主壁３１ａにおける電線Ｗｅの引出方向側の端面と第２シールドシェル部材３２のフランジ部３２ｅの平面との間の接触面、そして、第１シールドシェル部材３１の２つの固定部３１ｄの壁面と第２シールドシェル部材３２のフランジ部３２ｅの平面との間の接触面、更に、第１シールドシェル部材３１の主壁３１ａの溝部３１ａ１と第２シールドシェル部材３２の第１片部３２ｆとの間の接触面のことである。また、その隙間とは、ハウジング本体２１と第２シールドシェル部材３２の第２片部３２ｇとの間に形成される隙間のことである。 In the connector 1, the rubber boots 70 prevent water and dust from coming into contact with the braided member 35 from the outside. On the other hand, in this connector 1, since the shield shell 30 adopts a divided structure by the first shield shell member 31 and the second shield shell member 32, the mating surface between them, the second shield shell member 32, and the housing body 21 There is a possibility that water or dust may enter the shield shell 30 through a gap or the like between the two. The mating surface is a contact surface between the end surface of the main wall 31a of the first shield shell member 31 on the drawing direction side of the electric wire We and the plane of the flange portion 32e of the second shield shell member 32, and the first shield. The contact surface between the wall surfaces of the two fixing portions 31d of the shell member 31 and the flat surface of the flange portion 32e of the second shield shell member 32, and the grooves 31a 1 and the second of the main wall 31a of the first shield shell member 31. It is a contact surface between the first piece 32f of the shield shell member 32. Further, the gap is a gap formed between the housing main body 21 and the second piece portion 32g of the second shield shell member 32.

ここで、ハウジング２０においては、そのシールドシェル３０の中に入り込んだ水や塵埃が引出口２０ｄから収容室２０ｃに入り込んだとしても、端子側シール部材４３によって、その水や塵埃の端子金具１０への到達を抑止することができる。よって、このコネクタ１においては、先に示したように、水による端子金具１０の耐久性の低下や塵埃による端子金具１０の通電性能の低下を抑えることができる。 Here, in the housing 20, even if water or dust that has entered the shield shell 30 enters the storage chamber 20c from the outlet 20d, the terminal-side sealing member 43 will reach the terminal fitting 10 of the water or dust. Can be suppressed from reaching. Therefore, in this connector 1, as shown above, it is possible to suppress a decrease in the durability of the terminal fitting 10 due to water and a decrease in the energization performance of the terminal fitting 10 due to dust.

一方、このコネクタ１においては、シールドシェル３０の中に入り込んだ水や塵埃が第２シールドシェル部材３２の電線収容室３２ｂに入り込み、この電線収容室３２ｂの引出口３２ｃから抜け出てしまうと、その水や塵埃が編組部材３５に到達してしまう可能性があり、例えば、その水による編組部材３５の耐久性の低下を引き起こしてしまう虞がある。 On the other hand, in the connector 1, when water or dust that has entered the shield shell 30 enters the electric wire accommodating chamber 32b of the second shield shell member 32 and exits from the outlet 32c of the electric wire accommodating chamber 32b, the connector 1 is used. Water or dust may reach the braided member 35, and for example, the water may cause a decrease in the durability of the braided member 35.

そこで、このコネクタ１は、電線収容室３２ｂの内周壁と電線Ｗｅの第１引出部Ｗｅ１との間の隙間を埋めて、その間での防水と防塵を図るシール部材（以下、「編組側シール部材」という。）４５を備えている（図３及び図４）。この編組側シール部材４５は、合成ゴム等の弾性部材で成形される。 Therefore, this connector 1 fills a gap between the inner peripheral wall of the electric wire accommodating chamber 32b and the first lead-out portion We1 of the electric wire We, and is a sealing member for waterproofing and dustproofing between them (hereinafter, "braided side sealing member"). ”) 45 (FIGS. 3 and 4). The braided side seal member 45 is formed of an elastic member such as synthetic rubber.

この編組側シール部材４５は、電線Ｗｅ毎に設けたものであってもよく、電線収容室３２ｂの内周壁と複数本の電線Ｗｅの第１引出部Ｗｅ１との間の隙間を埋めるものであってもよい。ここで示す編組側シール部材４５は、電線収容室３２ｂの内周壁と２本の電線Ｗｅの第１引出部Ｗｅ１との間の隙間を埋めるものとして成形されている。 The braided side sealing member 45 may be provided for each electric wire We, and fills a gap between the inner peripheral wall of the electric wire accommodating chamber 32b and the first extraction portion We1 of the plurality of electric wires We. You may. The braided side seal member 45 shown here is formed so as to fill a gap between the inner peripheral wall of the electric wire accommodating chamber 32b and the first extraction portion We1 of the two electric wires We.

ここで示す編組側シール部材４５は、長円形に成形され、かつ、電線Ｗｅ毎の円形の貫通孔４５ａを有している（図４）。そして、この編組側シール部材４５においては、外周面に同軸の環状のリップ（以下、「外周リップ」という。）が形成され、かつ、その貫通孔４５ａの内周面に同軸の環状のリップ（以下、「内周リップ」という。）が形成されている。この編組側シール部材４５は、筒部３２ａの内周壁に外周リップを密着させ、かつ、電線Ｗｅの第１引出部Ｗｅ１の外周面に内周リップを密着させることによって、合わせ面等からシールドシェル３０の中に入り込んで電線収容室３２ｂに到達した水や塵埃の引出口３２ｃからの流出を抑止することができる。よって、このコネクタ１においては、合わせ面等からシールドシェル３０の中に入り込んできた水による編組部材３５の耐久性の低下を抑えることができる。 The braided side sealing member 45 shown here is formed in an oval shape and has a circular through hole 45a for each electric wire We (FIG. 4). In the braided side sealing member 45, a coaxial annular lip (hereinafter referred to as "outer peripheral lip") is formed on the outer peripheral surface, and a coaxial annular lip (hereinafter referred to as "outer peripheral lip") is formed on the inner peripheral surface of the through hole 45a. Hereinafter, "inner peripheral lip") is formed. The braided side sealing member 45 has a shield shell from a mating surface or the like by bringing the outer peripheral lip into close contact with the inner peripheral wall of the tubular portion 32a and the inner peripheral lip in close contact with the outer peripheral surface of the first drawing portion We1 of the electric wire We. It is possible to prevent the outflow of water and dust that have entered the electric wire accommodating chamber 32b and reached the electric wire accommodating chamber 32b from the outlet 32c. Therefore, in this connector 1, it is possible to suppress a decrease in the durability of the braided member 35 due to water entering the shield shell 30 from the mating surface or the like.

また、コネクタ１においては、この編組側シール部材４５が先に示した第１電線保持具６０と端子側シール部材４３よりも電線Ｗｅの引出方向側に配置されているので、引出部分から伝わってきた電線Ｗｅの振動が第１電線保持具６０と端子側シール部材４３に伝わる前に、この編組側シール部材４５で吸収される。よって、このコネクタ１においては、振動の端子金具１０への伝播抑止効果を更に高めることができる。 Further, in the connector 1, since the braided side sealing member 45 is arranged on the drawing direction side of the electric wire We from the first electric wire holder 60 and the terminal side sealing member 43 shown above, it is transmitted from the drawing portion. Before the vibration of the electric wire We is transmitted to the first electric wire holder 60 and the terminal side sealing member 43, it is absorbed by the braided side sealing member 45. Therefore, in this connector 1, the effect of suppressing the propagation of vibration to the terminal fitting 10 can be further enhanced.

更に、このコネクタ１は、第２シールドシェル部材３２の電線収容室３２ｂで電線Ｗｅを保持する電線保持具（以下、「第２電線保持具」という。）８０を備える（図３、図４、図１１及び図１２）。この第２電線保持具８０は、合成樹脂等の絶縁性材料で成形される。この第２電線保持具８０は、電線Ｗｅ毎に設けたものであってもよく、複数本の電線Ｗｅの保持が可能な１つの部品として設けたものであってもよい。ここで示す第２電線保持具８０は、複数本（この例示では２本）の電線Ｗｅの第１引出部Ｗｅ１の保持が可能な１つの部品として設けられている。また、ここで示す第２電線保持具８０は、先に示した第１電線保持具６０と同じように、同じ部品として成形された第１電線保持部材８１と第２電線保持部材８２とが組み付けられたものである（図３、図４、図１１及び図１２）。但し、ここで示す第２電線保持具８０は、先に示した第１電線保持具６０に対して次のような共通点と相違点を有している。 Further, the connector 1 includes an electric wire holder (hereinafter, referred to as “second electric wire holder”) 80 for holding the electric wire We in the electric wire accommodating chamber 32b of the second shield shell member 32 (FIGS. 3 and 4). 11 and 12). The second electric wire holder 80 is formed of an insulating material such as synthetic resin. The second electric wire holder 80 may be provided for each electric wire We, or may be provided as one component capable of holding a plurality of electric wires We. The second electric wire holder 80 shown here is provided as one component capable of holding the first lead-out portion We1 of a plurality of (two in this example) electric wires We. Further, in the second electric wire holder 80 shown here, the first electric wire holding member 81 and the second electric wire holding member 82 molded as the same parts are assembled in the same manner as the first electric wire holder 60 shown above. (Fig. 3, Fig. 4, Fig. 11 and Fig. 12). However, the second electric wire holder 80 shown here has the following commonalities and differences from the first electric wire holder 60 shown above.

第２電線保持具８０は、第１電線保持具６０の電線挿通部６０ａと同じ電線挿通部８０ａを有するものであるが、その電線挿通部６０ａに設けたリブ６０ｂの如き突起部を電線挿通部８０ａに有していない（図３、図１１及び図１２）。第１電線保持部材８１と第２電線保持部材８２は、第１電線保持具６０の第１電線保持部材６１及び第２電線保持部材６２に各々設けた空間部６５と同じ空間部８５を有しており（図１２）、第１電線保持具６０と同じように、それぞれの空間部８５を合わせた円柱状の空間部によって電線挿通部８０ａを形成する。 The second electric wire holder 80 has the same electric wire insertion portion 80a as the electric wire insertion portion 60a of the first electric wire holder 60, but the electric wire insertion portion has a protrusion such as a rib 60b provided on the electric wire insertion portion 60a. Not included in 80a (FIGS. 3, 11 and 12). The first electric wire holding member 81 and the second electric wire holding member 82 have the same space portion 85 as the space portion 65 provided in the first electric wire holding member 61 and the second electric wire holding member 62 of the first electric wire holder 60, respectively. (FIG. 12), similarly to the first electric wire holder 60, the electric wire insertion portion 80a is formed by the columnar space portion in which the respective space portions 85 are combined.

また、この第２電線保持具８０は、第１電線保持部材８１と第２電線保持部材８２との間に、第１電線保持部材６１と第２電線保持部材６２との間の第２ロック機構６４と同じロック機構８４｛第１係止体８４ａ、第２係止体８４ｂ（第２係止部８４ｂ１、可撓片部８４ｂ２）｝を有しているが、第１電線保持部材６１と第２電線保持部材６２との間の第１ロック機構６３に相当するものを有していない（図１１及び図１２）。 Further, the second electric wire holder 80 has a second lock mechanism between the first electric wire holding member 81 and the second electric wire holding member 82, and between the first electric wire holding member 61 and the second electric wire holding member 62. It has the same locking mechanism 84 as 64 {first locking body 84a, second locking body 84b (second locking portion 84b 1 , flexible piece portion 84b 2 )}, but the first electric wire holding member 61. It does not have the equivalent of the first lock mechanism 63 between the second electric wire holding member 62 and the second electric wire holding member 62 (FIGS. 11 and 12).

ここで、第２電線保持具８０は、編組側シール部材４５よりも端子金具１０側に配置してもよく、編組側シール部材４５よりも電線収容室３２ｂの引出口３２ｃ側に配置してもよい。この例示では、この第２電線保持具８０に関わる下記の突出部８０ｃと係止部（環状部３２ｄ）を設けるために、第２電線保持具８０を編組側シール部材４５よりも電線収容室３２ｂの引出口３２ｃ側に配置している（図３）。 Here, the second electric wire holder 80 may be arranged closer to the terminal fitting 10 than the braided side seal member 45, or may be arranged closer to the outlet 32c side of the electric wire accommodating chamber 32b than the braided side seal member 45. good. In this example, in order to provide the following protruding portion 80c and the locking portion (annular portion 32d) related to the second electric wire holder 80, the second electric wire holder 80 is installed in the electric wire accommodating chamber 32b rather than the braided side seal member 45. It is arranged on the outlet 32c side of the above (Fig. 3).

この第２電線保持具８０は、電線収容室３２ｂの引出口３２ｃよりも外方に突出させ、かつ、電線Ｗｅの第２引出部Ｗｅ２を収容させる筒状の突出部８０ｃを有する（図３、図１１及び図１２）。この突出部８０ｃは、電線Ｗｅ毎に設ける。第１電線保持部材８１と第２電線保持部材８２は、各々、電線挿通部８０ａの軸線方向における一方の端面８１ａ，８２ａから突出させた当該電線挿通部８０ａと同心の半円弧状の突出部８６を有している（図３及び図１２）。この第１電線保持部材８１と第２電線保持部材８２は、それぞれの突出部８６を合わせて円筒状の突出部８０ｃを形成する。このコネクタ１においては、この突出部８０ｃによって、電線収容室３２ｂの引出口３２ｃの周縁（環状部３２ｄの内周面）への電線Ｗｅの接触を防ぐことができるので、この電線Ｗｅの耐久性の低下を抑えることができる。 The second electric wire holder 80 has a tubular projecting portion 80c that projects outward from the outlet 32c of the electric wire accommodating chamber 32b and accommodates the second outlet portion We2 of the electric wire We (FIG. 3, FIG. 11 and 12). The protruding portion 80c is provided for each electric wire We. The first wire holding member 81 and the second wire holding member 82 are semicircular arc-shaped protrusions 86 that are concentric with the wire insertion portions 80a that protrude from one end surface 81a, 82a of the wire insertion portion 80a in the axial direction, respectively. (FIGS. 3 and 12). The first electric wire holding member 81 and the second electric wire holding member 82 combine the respective protruding portions 86 to form a cylindrical protruding portion 80c. In the connector 1, the protruding portion 80c can prevent the electric wire We from coming into contact with the peripheral edge of the outlet 32c of the electric wire accommodating chamber 32b (the inner peripheral surface of the annular portion 32d). Can be suppressed.

ここで、第２シールドシェル部材３２は、この第２電線保持具８０を電線収容室３２ｂの引出口３２ｃ側で係止させる係止部を有している。例えば、ここで示す第２シールドシェル部材３２においては、環状部３２ｄにおける電線収容室３２ｂ側の平面が第１電線保持部材８１と第２電線保持部材８２のそれぞれの端面８１ａ，８２ａに対向配置されている。そこで、このコネクタ１においては、その環状部３２ｄを第２電線保持具８０用の係止部として利用し、この係止部（環状部３２ｄ）によって、第２電線保持具８０が電線収容室３２ｂから引出口３２ｃ側に抜け出てしまうことを防止できる。そして、このコネクタ１においては、その第２電線保持具８０が編組側シール部材４５の引出口３２ｃ側への動きを係止させるので、編組側シール部材４５が電線収容室３２ｂから引出口３２ｃ側に抜け出てしまうことも防止できる。 Here, the second shield shell member 32 has a locking portion for locking the second electric wire holder 80 on the outlet 32c side of the electric wire accommodating chamber 32b. For example, in the second shield shell member 32 shown here, the flat surface of the annular portion 32d on the wire accommodating chamber 32b side is arranged to face the end faces 81a and 82a of the first wire holding member 81 and the second wire holding member 82, respectively. ing. Therefore, in this connector 1, the annular portion 32d is used as a locking portion for the second electric wire holder 80, and the locking portion (annular portion 32d) allows the second electric wire holder 80 to be placed in the electric wire accommodating chamber 32b. It is possible to prevent the cable from coming out to the outlet 32c side. Then, in this connector 1, since the second electric wire holder 80 locks the movement of the braided side seal member 45 toward the outlet 32c side, the braided side seal member 45 is moved from the electric wire accommodating chamber 32b to the outlet 32c side. It is also possible to prevent it from slipping out.

このコネクタ１においては、この第２電線保持具８０が先に示した第１電線保持具６０と端子側シール部材４３と編組側シール部材４５よりも電線Ｗｅの引出方向側に配置されているので、引出部分から伝わってきた電線Ｗｅの振動が第１電線保持具６０と端子側シール部材４３と編組側シール部材４５に伝わる前に、この第２電線保持具８０で抑えられる。よって、このコネクタ１においては、振動の端子金具１０への伝播抑止効果を更に高めることができる。更に、このコネクタ１においては、この第２電線保持具８０が電線収容室３２ｂの中での電線Ｗｅの振れを抑え、電線Ｗｅの振れに伴う編組側シール部材４５の押し潰しを抑止できるので、電線Ｗｅと編組側シール部材４５との間に隙間ができ難くなっており、編組側シール部材４５による防水性能と防塵性能を向上させることができる。 In this connector 1, since the second electric wire holder 80 is arranged on the pull-out direction side of the electric wire We from the first electric wire holder 60, the terminal side sealing member 43, and the braided side sealing member 45 shown above. The vibration of the electric wire We transmitted from the drawer portion is suppressed by the second electric wire holder 80 before being transmitted to the first electric wire holder 60, the terminal side sealing member 43, and the braided side sealing member 45. Therefore, in this connector 1, the effect of suppressing the propagation of vibration to the terminal fitting 10 can be further enhanced. Further, in the connector 1, the second electric wire holder 80 suppresses the runout of the electric wire We in the electric wire accommodating chamber 32b, and can suppress the crushing of the braided side seal member 45 due to the runout of the electric wire We. It is difficult to create a gap between the electric wire We and the braided side sealing member 45, and the waterproof performance and dustproof performance of the braided side sealing member 45 can be improved.

以上示したように、本実施形態のワイヤハーネスＷＨは、車両走行時に電線Ｗｅの引出部分で発生した振れがコネクタ１に振動として伝わってきたとしても、その振動の端子金具１０への伝播を第１電線保持具６０と保持部２０ｇで抑止することができる。従って、このワイヤハーネスＷＨは、例えば、端子金具１０と相手方端子金具とが互いを嵌合接続させるものである場合、端子金具１０と相手方端子金具との間の接点における接触圧力の変化を抑えることができるので、その相互間での通電性能を良好なままに保つことができる。また、このワイヤハーネスＷＨは、例えば、端子金具１０と相手方端子金具とが互いを螺子止め固定させるものである場合、端子金具１０と相手方端子金具との間での過荷重の発生を抑えることができるので、これらの耐久性の低下を抑止することができる。更に、このワイヤハーネスＷＨは、収容室２０ｃの中での電線Ｗｅの振れも抑えられるので、電線Ｗｅと端子側シール部材４３との間に隙間ができ難く、端子側シール部材４３による防水性能と防塵性能を向上させることができる。 As shown above, in the wire harness WH of the present embodiment, even if the vibration generated at the lead-out portion of the electric wire We is transmitted to the connector 1 as vibration when the vehicle is running, the vibration is propagated to the terminal fitting 10. 1 It can be suppressed by the wire holder 60 and the holding portion 20g. Therefore, in this wire harness WH, for example, when the terminal fitting 10 and the mating terminal fitting are fitted and connected to each other, the change in the contact pressure at the contact point between the terminal fitting 10 and the mating terminal fitting is suppressed. Therefore, the energization performance between the two can be maintained in good condition. Further, in this wire harness WH, for example, when the terminal fitting 10 and the mating terminal fitting are screwed and fixed to each other, it is possible to suppress the occurrence of an overload between the terminal fitting 10 and the mating terminal fitting. Therefore, it is possible to suppress such a decrease in durability. Further, since this wire harness WH also suppresses the runout of the electric wire We in the accommodation chamber 20c, it is difficult for a gap to be formed between the electric wire We and the terminal side sealing member 43, and the waterproof performance of the terminal side sealing member 43 is improved. Dustproof performance can be improved.
