Description

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

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。 2. Description of the Related Art Conventionally, a known wire harness is configured as a connector-equipped electric wire in which a connector is attached to the end of the electric wire. In the connector, terminal fittings are electrically connected to terminals of electric wires in the housing, and the electric wires are led out of the housing. In the wire harness, the connector is fitted and connected to the terminal block or the mating connector, and along with this, 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 Wire harnesses of this type are disclosed, for example, in Patent Documents 1 to 3 below.

特開２０１４－１０７１５２号公報JP 2014-107152 A 特開２０１６－１９２３５９号公報JP 2016-192359 A 特開２０１８－４１５５４号公報JP 2018-41554 A

ところで、ワイヤハーネスは、電線や端子金具、ハウジング等の様々な部品が互いに組み付けられたものである。そして、ハウジング等は、金属製の端子金具等と比較して寸法公差の大きい合成樹脂材料で成形されている。このため、ワイヤハーネスにおいては、それぞれの部品の寸法公差や部品間の組付けばらつき等の各種公差を積み上げていくと、その積み上げ公差（所謂累積公差）が大きなものになってしまう可能性がある。よって、ワイヤハーネスは、その積み上げ公差を考慮した上で、コネクタを端子台等に嵌合接続させる際に端子金具と相手方端子金具とが物理的に接続可能な位置関係となるよう構成しておく必要がある。 By the way, a wire harness is a structure in which various parts such as electric wires, terminal fittings, and housings are assembled together. The housing and the like are molded from a synthetic resin material having a larger dimensional tolerance than metal terminal fittings and the like. For this reason, in the wire harness, if various tolerances such as dimensional tolerance of each part and assembly variation between parts are accumulated, the accumulated tolerance (so-called cumulative tolerance) may become large. . Therefore, the wire harness should be configured so that the terminal fitting and the mating terminal fitting can be physically connected when the connector is fit-connected to the terminal block, etc., after considering the stacking tolerance. There is a need.

そこで、本発明は、端子金具の調芯が可能なワイヤハーネスを提供することを、その目的とする。 SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a wire harness in which terminal fittings can be aligned.

It has a terminal fitting and a fitting portion that is inserted and fitted into a mating fitting portion, and the electric wire and the terminal fitting are housed in an inner housing chamber while the electric wire is pulled out of the outlet of the housing chamber. and a terminal holding member that is accommodated in a terminal accommodating portion inside the fitting portion in the accommodating chamber and holds the terminal metal fitting in the terminal accommodating portion, The terminal holding member is held by the housing so as to be capable of relative movement on a virtual plane perpendicular to the insertion/removal direction between the fitting portion and the mating fitting portion, and the housing comprises: By inserting the terminal holding member into the accommodation chamber toward the insertion direction side of the fitting portion with respect to the mating fitting portion, the terminal holding member is disposed opposite to the insertion direction side than the terminal holding member in the terminal accommodation portion, and a first locking portion that locks relative movement of the terminal holding member in the insertion direction side thereof; and a second locking portion disposed on the side of the terminal holding member for locking relative movement of the terminal holding member in the withdrawal direction, wherein the terminal holding member is the terminal accommodating portion of the terminal holding member. It is characterized by having a claw-shaped second locked portion that is arranged opposite to the second locking portion on the removal direction side at the accommodation completion position of .

［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８に基づいて説明する。 [Embodiment]
One embodiment of a wire harness according to the present invention will be described with reference to FIGS. 1 to 8. FIG.

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 numeral WH in FIGS. 1 to 4 indicates the wire harness of this embodiment. The wire harness WH is a so-called connector-equipped electric wire, and includes an electric wire We and a connector 1 attached to an end of the electric wire We. The wire harness WH shown here includes a connector 1 having a plurality of poles, and is provided with electric wires We corresponding in number to the number of poles. In this illustration, the wire harness WH includes two electric 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 a mating terminal fitting (not shown) by inserting the connector 1 into a mating fitting portion (not shown) from the tip thereof. For example, the connector 1 shown here is configured such that a fitting portion 20a of a housing 20, which will be described later, is inserted and fitted inside a hole-shaped counterpart fitting portion having an inner peripheral wall surface. The connector 1 allows the fitting portion 20a to be inserted into and pulled out of the hole-shaped counterpart fitting portion along the hole axis direction of the counterpart fitting portion. The mating fitting portion is formed, for example, so that a cross section perpendicular to the hole axial direction forms a rectangle. The counterpart fitting portion may be formed in a tubular shape, and the fitting portion 20a may be inserted and fitted into the inner space thereof.

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 electrically connects the mating device (not shown) to a mating device (not shown) connected to the wire We by electrically connecting the mating device to the mating terminal fitting. The mating device has a metal housing, and a through hole formed in the wall of the housing is used as a mating fitting portion. In addition, the mating device has a terminal block or a mating connector inside its housing. The mating terminal fitting is provided by the terminal block or the mating connector. Accordingly, the connector 1 has the fitting portion 20a inserted and fitted inside the mating fitting 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 description, the term "insertion direction" refers to the direction in which the fitting portion 20a of the connector 1 is inserted into the mating fitting portion. In addition, when simply referred to as a withdrawal direction without any particular reference, the withdrawal direction indicates the withdrawal direction of the fitting portion 20a of the connector 1 with respect to the counterpart fitting portion. In addition, when simply referred to as an insertion/removal direction without any particular reference, the insertion/removal direction indicates the insertion/removal direction of the fitting portion 20a of the connector 1 with respect to the counterpart fitting portion.

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 noise reduction (see 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 made of a conductive material such as metal. For example, the terminal metal fitting 10 is formed into a predetermined shape by press forming such as bending and cutting of 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。 This terminal fitting 10 has a terminal connection portion 11 that is physically and electrically connected to a counterpart terminal connection portion of the counterpart terminal fitting (FIGS. 1, 3 and 4). For example, the terminal connecting 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 connecting portion 11 and the mating terminal connecting 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 counterpart terminal connection portion may be screwed and fixed to each other. In this example, the terminal connecting portion 11 is formed in the shape of a cylindrical female terminal, and the mating terminal connecting portion is formed in the shape of a shaft-like male terminal to be fitted inside the terminal connecting portion 11 . In the terminal fitting 10, the axial direction of the terminal connecting portion 11 is the insertion/removal direction. An elastically deformable contact member (not shown) is assembled inside the illustrated terminal connection portion 11 .

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。 This terminal fitting 10 is electrically connected directly or indirectly to the end of the electric wire We. For example, the terminal fitting 10 is directly electrically connected to the end of the electric wire We by providing the electric wire connection portion 12 that is physically and electrically connected to the end of the electric wire We (FIGS. 3 and 4). Figure 4). Further, for example, the terminal fitting 10 is indirectly electrically connected to the end of the electric wire We by interposing a relay terminal (not shown) between the terminal fitting 10 and the end of the electric wire We. The terminal fitting 10 shown here has a wire connecting portion 12 and is electrically connected directly to the end of the 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 wire connecting portion 12 is physically and electrically connected to the wire We by, for example, crimping or welding the exposed core wire of the end of the wire We. The wire connecting portion 12 shown here is made by crimping two barrel pieces onto an exposed core wire. The electric wire We is pulled 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 in a straight shape such that the cylindrical axis direction of the terminal connection portion 11 and the lead-out direction of the wire We in the wire connection portion 12 are the same. When using the straight-shaped terminal fitting 10, the electric wire We drawn out from the wire connecting portion 12 may be extended in the drawing direction as it is and housed in the housing 20. The We may be bent halfway and stored in the housing 20 . In this example, a straight-shaped terminal fitting 10 and a wire We bent 90 degrees after being pulled out from a wire connection portion 12 are housed in a housing 20 (FIGS. 3 and 4).

尚、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の引出方向とを交差させた（例えば、直交させた）交差形状に成形されたものであってもよい。この場合には、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る。 The terminal fitting 10 may be formed in a cross shape in which the cylindrical axis direction of the terminal connection portion 11 and the lead-out direction of the electric wire We in the wire connection portion 12 are crossed (for example, perpendicular to each other). . In this case, the wire We pulled out from the wire connecting portion 12 is allowed to extend in the pull-out direction as it is.

このコネクタ１は、その対になる端子金具１０と電線Ｗｅの組み合わせを複数組備えている。ここでは、その組み合わせを２組備えている（図４）。このコネクタ１においては、２つの端子金具１０が挿抜方向に対する直交方向に並べて配置されている。また、このコネクタ１においては、２本の電線Ｗｅをその直交方向に並べて並走させている。 This connector 1 has a plurality of combinations of terminal metal fittings 10 and electric wires We that are paired with each other. Two such combinations are provided here (FIG. 4). In this connector 1, two terminal fittings 10 are arranged side by side in a direction orthogonal to the insertion/removal direction. Further, in this connector 1, two electric wires We are arranged in the orthogonal direction and run in parallel.

ハウジング２０は、合成樹脂等の絶縁性材料で成形される。 The housing 20 is molded from an insulating material such as synthetic resin.

このハウジング２０は、相手方嵌合部に挿入嵌合させる嵌合部２０ａを有する（図１から図６）。ここで示す嵌合部２０ａは、挿入方向に沿って孔状の相手方嵌合部の内方に挿入嵌合させ、これとは逆向きの抜去方向に沿って相手方嵌合部の内方から抜き取られる。この嵌合部２０ａは、相手方嵌合部に対する挿抜方向（挿入方向、挿抜方向）を筒軸方向とする筒状に形成されている。ここで示す嵌合部２０ａは、角筒状に形成されている。 This housing 20 has a fitting portion 20a that is inserted and fitted into the mating fitting portion (FIGS. 1 to 6). The fitting portion 20a shown here is inserted and fitted inside the hole-shaped mating fitting portion along the insertion direction, and pulled out from the inside of the mating fitting portion along the withdrawal direction opposite to this. be The fitting portion 20a is formed in a cylindrical shape with the insertion/removal direction (insertion direction, insertion/removal direction) with respect to the mating fitting portion being the cylinder axis direction. The fitting portion 20a shown here is formed in a rectangular tubular shape.

コネクタ１は、この嵌合部２０ａと相手方嵌合部との間の環状の隙間を埋めて、その間での防水と防塵を図る環状のシール部材４１を備える（図１から図４）。このシール部材４１は、合成ゴム等の弾性部材で成形される。そして、このシール部材４１は、嵌合部２０ａの外周面に組み付けられる。 The connector 1 is provided with an annular seal member 41 that fills the annular gap between the mating portion 20a and the mating mating portion to provide water and dust protection therebetween (FIGS. 1 to 4). This seal member 41 is molded from an elastic member such as synthetic rubber. The seal member 41 is attached to the outer peripheral surface of the fitting portion 20a.

更に、ハウジング２０は、その嵌合部２０ａの外周面の外側に鍔状のフランジ部２０ｂを有している（図１、図３、図５及び図６）。このフランジ部２０ｂは、嵌合部２０ａと相手方嵌合部とが嵌合完了状態のときに、その相手方嵌合部の周縁の壁面に間隔を空けて対向配置させる対向壁面を有する。コネクタ１は、このフランジ部２０ｂの対向壁面と相手方嵌合部の周縁の壁面との間の隙間を埋めて、その間での防水と防塵を図る環状のシール部材４２を備える（図１及び図３）。このシール部材４２は、合成ゴム等の弾性部材で成形される。そして、このシール部材４２は、フランジ部２０ｂの対向壁面に形成されている環状溝に突出状態で嵌め込まれる。 Further, the housing 20 has a brim-shaped flange portion 20b outside the outer peripheral surface of the fitting portion 20a (FIGS. 1, 3, 5 and 6). The flange portion 20b has an opposing wall surface that is spaced apart from the wall surface of the peripheral edge of the mating fitting portion when the fitting portion 20a and the mating fitting portion are in a mated state. The connector 1 is provided with an annular seal member 42 that fills the gap between the opposing wall surface of the flange portion 20b and the peripheral wall surface of the mating fitting portion to prevent water and dust from occurring therebetween (see FIGS. 1 and 3). ). The seal member 42 is molded from an elastic member such as synthetic rubber.

以上示したように、本実施形態のワイヤハーネスＷＨは、ハウジング２０の嵌合部２０ａに対して端子保持部材５０を挿抜方向に対する直交方向に相対移動させることができるので、嵌合部２０ａと相手方嵌合部とを挿入嵌合させる際に、端子接続部１１を相手方端子接続部に対する物理的な接続が可能な位置に動かすことができる。よって、このワイヤハーネスＷＨは、各部品等の積み上げ公差に拘わらず、端子金具１０と相手方端子金具とを物理的に接続させることができる。具体的に、このワイヤハーネスＷＨは、嵌合部２０ａと相手方嵌合部とが途中でぶつかって、嵌合部２０ａと相手方嵌合部の挿入嵌合作業が嵌合完了状態となる前に止まる半嵌合状態の発生を抑止することができる。更に、このワイヤハーネスＷＨは、嵌合部２０ａと相手方嵌合部との間に過荷重を発生させないので、これらの耐久性を向上させることができる。また更に、このワイヤハーネスＷＨは、簡易な構造で端子金具１０を調芯させることができるので、原価の高騰を抑えることができる。 As described above, in the wire harness WH of the present embodiment, the terminal holding member 50 can be moved relative to the fitting portion 20a of the housing 20 in the direction orthogonal to the insertion/removal direction. When inserting and fitting the fitting portion, the terminal connection portion 11 can be moved to a position where physical connection to the mating terminal connection portion is possible. Therefore, the wire harness WH can physically connect the terminal fitting 10 and the mating terminal fitting regardless of the stacking tolerance of each part. Specifically, the wire harness WH stops before the mating operation of the fitting portion 20a and the mating fitting portion reaches a fitting completion state because the mating portion 20a and the mating fitting portion collide in the middle. It is possible to suppress the occurrence of the half-fitted state. Furthermore, since this wire harness WH does not generate an excessive load between the fitting portion 20a and the mating fitting portion, it is possible to improve their durability. Furthermore, since the wire harness WH can align the terminal metal fitting 10 with a simple structure, it is possible to suppress an increase in cost.
