ところで、アース用端子金具の配設箇所によっては、端子本体に対して直交する方向に電線を引出すように要請される場合がある。   By the way, depending on the location of the grounding terminal fitting, it may be requested to pull out the electric wire in a direction perpendicular to the terminal body.

この場合、直線状に形成されたアース用端子の電線接続部に対して直交する姿勢で芯線を接続する場合と、端子本体と電線接続部とをL字状に形成し、その電線接続部に芯線を接続する場合とが考えられる。   In this case, when connecting the core wire in a posture orthogonal to the wire connection portion of the grounding terminal formed in a straight line, the terminal body and the wire connection portion are formed in an L shape, and the wire connection portion The case where a core wire is connected is considered.

以下、第1実施形態に係る端子付電線及び端子について説明する。図1は端子付電線20を示す概略平面図であり、図2は端子付電線20を示す概略側面図である。
{First embodiment}
Hereinafter, the electric wire with terminal and the terminal according to the first embodiment will be described. FIG. 1 is a schematic plan view showing the terminal-attached electric wire 20, and FIG. 2 is a schematic side view showing the terminal-attached electric wire 20.

端子付電線20は、自動車等に組込まれ、車両の各部を電気的に接続するための配線材として用いられる。ここでは、端子30がアース端子であり、車両のアース接続部位10に突設されたボルト12が端子30に挿通された状態で、ナット14がボルト12に締結され、もって、端子30がアース接続部位10に電気的に接続された状態で、当該アース接続部位10に固定される例で説明する。   The terminal-attached electric wire 20 is incorporated in an automobile or the like, and is used as a wiring material for electrically connecting each part of the vehicle. Here, the terminal 30 is a ground terminal, and the nut 14 is fastened to the bolt 12 in a state where the bolt 12 protruding from the ground connection portion 10 of the vehicle is inserted into the terminal 30, so that the terminal 30 is grounded. An example will be described in which the part 10 is fixed to the ground connection part 10 while being electrically connected to the part 10.

端子付電線20は、電線22と、端子30と、チューブ40とを備える。   The terminal-attached electric wire 20 includes an electric wire 22, a terminal 30, and a tube 40.

電線22は、芯線部24と芯線部24の周囲に形成された被覆部26とを備える。芯線部24は、銅、銅合金、アルミニウム、アルミニウム合金等の導電性材料によって線状に形成されている。ここでは、芯線部24は、複数の素線が撚り合わされた構成とされている。もっとも、芯線部は、単線によって構成されていてもよい。被覆部26は、絶縁性樹脂材料が押出装置等により芯線部24の周りに押し出されることによって形成される。この電線22の先端部には、芯線部24が露出しており、所定長の露出芯線部24aが形成されている。ここでは、露出芯線部24aの中間部及び先端部は、複数の素線同士が一体となるように超音波溶接、半田付等によって接合されている。   The electric wire 22 includes a core wire portion 24 and a covering portion 26 formed around the core wire portion 24. The core wire portion 24 is formed in a linear shape from a conductive material such as copper, copper alloy, aluminum, or aluminum alloy. Here, the core wire portion 24 has a configuration in which a plurality of strands are twisted together. But the core wire part may be comprised by the single wire. The covering portion 26 is formed by extruding the insulating resin material around the core wire portion 24 by an extrusion device or the like. The core wire portion 24 is exposed at the tip end portion of the electric wire 22, and an exposed core wire portion 24a having a predetermined length is formed. Here, the intermediate part and the front-end | tip part of the exposed core part 24a are joined by ultrasonic welding, soldering, etc. so that several strands may be united.

端子30は、例えば、銅又は銅合金等によって形成された板材をプレス加工等することによって形成された部材である。端子30の表面には、錫メッキ等が施されていてもよい。   The terminal 30 is a member formed by, for example, pressing a plate material formed of copper or a copper alloy. Tin plating or the like may be applied to the surface of the terminal 30.

この端子30は、端子本体部32と芯線接続部36とを備える。端子本体部32の一端部に、芯線接続部36が連なっている。   The terminal 30 includes a terminal body portion 32 and a core wire connection portion 36. A core wire connecting portion 36 is connected to one end portion of the terminal main body portion 32.

端子本体部32は、長尺状、より具体的には、長方形板状に形成されている。この端子本体部32の他端部には、ボルト12を挿通可能なボルト挿通孔33hが形成されている。そして、ボルト12をボルト挿通孔33hに通すようにして、上記アース接続部位10上に端子本体部32の他端部を配設する。この後、ナット14をボルト12に締付け、アース接続部位10とナット14との間に、端子本体部32を挟込む。これにより、端子本体部32がアース接続部位10に対して一定姿勢で固定されると共に、端子本体部32がアース接続部位10、ボルト12及びナット14に接触し、もって、本端子30がアース接続される。   The terminal body 32 is formed in a long shape, more specifically, a rectangular plate shape. A bolt insertion hole 33 h into which the bolt 12 can be inserted is formed at the other end of the terminal main body 32. Then, the other end portion of the terminal main body portion 32 is disposed on the ground connection portion 10 so as to pass the bolt 12 through the bolt insertion hole 33h. Thereafter, the nut 14 is fastened to the bolt 12, and the terminal main body portion 32 is sandwiched between the ground connection portion 10 and the nut 14. As a result, the terminal main body 32 is fixed in a fixed posture with respect to the ground connection part 10, and the terminal main body 32 comes into contact with the ground connection part 10, the bolt 12 and the nut 14. Is done.

端子30をアース接続部位10に固定する際には、当該アース接続部位10の形状等に応じて、端子本体部32を延出させるべき方向が規制される場合がある。図1に示す例では、ボルト12の両側の突起部11の制約によって、端子本体部32が図1に左方向に延出するように、アース接続部位10に固定される例を示している。   When the terminal 30 is fixed to the ground connection part 10, the direction in which the terminal main body portion 32 should be extended may be restricted depending on the shape of the ground connection part 10 or the like. In the example shown in FIG. 1, an example is shown in which the terminal main body 32 is fixed to the ground connection portion 10 so as to extend leftward in FIG. 1 due to the restriction of the protrusions 11 on both sides of the bolt 12.

なお、ここでは、端子本体部32の一端部の外周囲は、半円を描くように丸められているがこれは必須ではない。   Here, the outer periphery of one end of the terminal main body 32 is rounded so as to draw a semicircle, but this is not essential.

芯線接続部36は、端子本体部32の一端部に連なる長尺状に形成されている。より具体的には、上記端子本体部32の一端部の側部に、その外方に延出するようにして長方形板状の芯線接続部36が連なっている。端子本体部32と芯線接続部36とは、1枚の板材を打抜くことによって形成されている。端子本体部32と芯線接続部36とが平面上に展開した状態で、上記芯線接続部36の延在方向は、端子本体部32の延在方向に対して直交している。   The core wire connecting portion 36 is formed in a long shape that is continuous with one end portion of the terminal main body portion 32. More specifically, a rectangular plate-shaped core wire connecting portion 36 is connected to the side portion of one end portion of the terminal main body portion 32 so as to extend outward. The terminal main body portion 32 and the core wire connecting portion 36 are formed by punching one plate material. In a state where the terminal main body portion 32 and the core wire connecting portion 36 are developed on a plane, the extending direction of the core wire connecting portion 36 is orthogonal to the extending direction of the terminal main body portion 32.

そして、芯線接続部36の少なくとも一部が端子本体部32の少なくとも一部に被さるように、芯線接続部36が端子本体部32に対して交差するように折曲げられている。より具体的には、芯線接続部36の基端部がU字状に曲げられている。つまり、芯線接続部36は、端子本体部32に対して180度曲げられている。芯線接続部36の中間部が端子本体部32の基端部に対して間隔をあけて重なるように、芯線接続部36が端子本体部32に対して折返されている。ここでは、芯線接続部36の中間部及び先端部が端子本体部32の基端部に対して間隔をあけて重なっている。芯線接続部36と端子本体部32の間隔寸法は、後述するチューブ40を外嵌めすることができるように、当該チューブ40の厚み以上の寸法であることが好ましい。   The core wire connection part 36 is bent so as to intersect the terminal main body part 32 so that at least a part of the core wire connection part 36 covers at least a part of the terminal main body part 32. More specifically, the proximal end portion of the core wire connecting portion 36 is bent in a U shape. That is, the core wire connecting portion 36 is bent 180 degrees with respect to the terminal main body portion 32. The core wire connection part 36 is folded back with respect to the terminal main body part 32 so that the intermediate part of the core wire connection part 36 overlaps the base end part of the terminal main body part 32 with a gap. Here, the intermediate portion and the distal end portion of the core wire connecting portion 36 overlap with the proximal end portion of the terminal main body portion 32 with a space therebetween. It is preferable that the space | interval dimension of the core wire connection part 36 and the terminal main-body part 32 is a dimension more than the thickness of the said tube 40 so that the tube 40 mentioned later can be externally fitted.

このように芯線接続部36が曲げられた状態では、芯線接続部36は、端子本体部32に対して交差している。ここでは、端子本体部32を平面視した状態において、芯線接続部36は、端子本体部32に対して直交するように折曲げられている。   In this state where the core wire connection portion 36 is bent, the core wire connection portion 36 intersects the terminal main body portion 32. Here, the core wire connecting part 36 is bent so as to be orthogonal to the terminal main body part 32 in a state in which the terminal main body part 32 is viewed in plan.

上記露出芯線部24aは、その延在方向を芯線接続部36の延在方向に沿わせた姿勢で、芯線接続部36に接続されている。電線22の中間部は、芯線接続部36の先端側、すなわち、端子本体部32に対する曲げ箇所とは反対側に延出している。   The exposed core wire portion 24 a is connected to the core wire connecting portion 36 in a posture in which the extending direction is along the extending direction of the core wire connecting portion 36. The intermediate portion of the electric wire 22 extends to the distal end side of the core wire connecting portion 36, that is, the side opposite to the bent portion with respect to the terminal main body portion 32.

ここでは、露出芯線部24aは、芯線接続部36に対して、超音波溶接、抵抗溶接、半田付等によって接合されている。ここでは、芯線接続部36の両面のうち端子本体部32とは逆側の面に、露出芯線部24aが接合されている。もっとも、芯線接続部の両面のうち端子本体部側の面に、露出芯線部が接合されていてもよい。その場合、芯線接続部と端子本体部との間に、露出芯線部を配設可能な隙間を設ける必要があり、端子の大型化要因となる。本実施形態では、芯線接続部36の両面のうち端子本体部32とは逆側の面に、露出芯線部24aが接合されているため、その点からも端子30の小型化が図られている。   Here, the exposed core wire portion 24a is joined to the core wire connecting portion 36 by ultrasonic welding, resistance welding, soldering, or the like. Here, the exposed core wire portion 24 a is joined to the surface opposite to the terminal main body portion 32 of both surfaces of the core wire connecting portion 36. But the exposed core part may be joined to the surface by the side of a terminal body part among both surfaces of a core wire connection part. In that case, it is necessary to provide a gap in which the exposed core portion can be disposed between the core wire connecting portion and the terminal main body portion, which causes an increase in the size of the terminal. In the present embodiment, since the exposed core portion 24a is joined to the opposite surface of the core wire connecting portion 36 to the terminal main body portion 32, the size of the terminal 30 is also reduced from that point. .

また、電線22の被覆部26の端縁部は、芯線接続部36の先端部外方に位置しているが、芯線接続部36上に位置していてもよい。   Moreover, although the edge part of the coating | coated part 26 of the electric wire 22 is located outside the front-end | tip part of the core wire connection part 36, you may be located on the core wire connection part 36. FIG.

露出芯線部24aと芯線接続部36との接続構成は、上記例に限られない。例えば、芯線接続部の両側部に圧着片を設け、この圧着片を露出芯線部にかしめることによって、芯線接続部と露出芯線部とが接続されていてもよい。もっとも、圧着片をかしめるためには、かしめ用の金型を芯線接続部の両面側に配設する必要がある。そのための作業スペースを確保するためには、芯線接続部36を端子本体部32に対して曲げる前の状態で、圧着片を露出芯線部に対してかしめる作業を行うようにすればよい。   The connection configuration of the exposed core wire portion 24a and the core wire connection portion 36 is not limited to the above example. For example, the core wire connection portion and the exposed core wire portion may be connected by providing crimp pieces on both sides of the core wire connection portion and caulking the crimp pieces to the exposed core wire portion. However, in order to caulk the crimping piece, it is necessary to dispose caulking dies on both sides of the core wire connecting portion. In order to secure a working space for that purpose, the crimping piece may be crimped to the exposed core wire portion in a state before the core wire connecting portion 36 is bent with respect to the terminal main body portion 32.

もっとも、超音波溶接、抵抗溶接、半田付等であれば、芯線接続部36の一方面には大きな作業スペースを確保する必要はないため、芯線接続部36を端子本体部32に対して曲げた後の状態でも、芯線接続部36に対する露出芯線部24aの接続作業を容易に行える。   Of course, in the case of ultrasonic welding, resistance welding, soldering, etc., it is not necessary to secure a large working space on one surface of the core wire connection portion 36, so the core wire connection portion 36 is bent with respect to the terminal body portion 32. Even in the later state, the connecting operation of the exposed core wire portion 24a to the core wire connecting portion 36 can be easily performed.

チューブ40は、芯線接続部36と露出芯線部24aとの接続部37を覆っている。より具体的には、チューブ40は、芯線接続部36のうち露出芯線部24aよりも先端側の部分から、芯線接続部36と露出芯線部24aとの接続部37を経て、被覆部26の先端側の外周囲の部分を覆っている。   The tube 40 covers the connecting portion 37 between the core wire connecting portion 36 and the exposed core wire portion 24a. More specifically, the tube 40 is connected to the distal end of the covering portion 26 from the distal end portion of the core wire connecting portion 36 with respect to the exposed core wire portion 24a through the connecting portion 37 between the core wire connecting portion 36 and the exposed core wire portion 24a. Covers the outer perimeter of the side.

チューブ40は、熱収縮性を有する樹脂材料により筒状に形成された熱収縮チューブである。チューブ40は、収縮前の状態では、芯線接続部36と露出芯線部24aとの接続部37を通すことが可能な程度の内径を有している。そして、収縮前のチューブ40が芯線接続部36と露出芯線部24aとの接続部37を覆った状態で、加熱されると、収縮していく。この際、芯線接続部36は、端子本体部32に対して交差する方向に延在し、端子本体部32の側方に向けて延出しているので、当該芯線接続部36及びこれに接続された露出芯線部24aに対して、チューブ40を容易に外嵌めすることができる。最終的には、チューブ40は、芯線接続部36と露出芯線部24aとの接続部37及びその周囲部分の外周囲に密着する程度に収縮する。特に、露出芯線部24aの先端側では、芯線接続部36の外周囲に密着する程度に収縮することが好ましい。また、被覆部26の先端部ではその外周囲に密着する程度に収縮することが好ましい。これにより、チューブ40と接続部37の周囲部分の間から水等の液体が浸入することを抑制することができ、上記接続部37への水の付着を抑制できる。   The tube 40 is a heat-shrinkable tube formed in a cylindrical shape from a heat-shrinkable resin material. The tube 40 has an inner diameter that allows the connecting portion 37 between the core wire connecting portion 36 and the exposed core wire portion 24a to pass through in a state before contraction. And if the tube 40 before shrinkage | heated in the state which covered the connection part 37 of the core wire connection part 36 and the exposed core wire part 24a, it will shrink | contract. At this time, the core wire connecting portion 36 extends in a direction intersecting the terminal main body portion 32 and extends toward the side of the terminal main body portion 32, so that the core wire connecting portion 36 and the core wire connecting portion 36 are connected thereto. The tube 40 can be easily fitted onto the exposed core portion 24a. Eventually, the tube 40 contracts to such an extent that it adheres closely to the connection portion 37 between the core wire connection portion 36 and the exposed core wire portion 24a and the outer periphery of the peripheral portion. In particular, it is preferable that the exposed core wire portion 24a contracts to the extent that it is in close contact with the outer periphery of the core wire connecting portion 36 at the distal end side. Moreover, it is preferable to shrink | contract so that it may contact | adhere to the outer periphery at the front-end | tip part of the coating | coated part 26. Thereby, it can suppress that liquids, such as water, permeate from between the tube 40 and the peripheral parts of the connection part 37, and can suppress adhesion of the water to the said connection part 37. FIG.

チューブ40内には、ホットメルト接着剤等の接着層が設けられていることが好ましい。これにより、チューブ40と接続部37の周囲部分の間の隙間をより確実に埋めることができる。もっとも、このような接着層が設けられていることは必須ではない。   An adhesive layer such as a hot melt adhesive is preferably provided in the tube 40. Thereby, the clearance gap between the tube 40 and the peripheral part of the connection part 37 can be filled more reliably. However, it is not essential that such an adhesive layer is provided.

このように構成された端子付電線20及び端子30によると、芯線接続部36が端子本体部32に対して交差するように折曲げられており、電線22の露出芯線部24aが、その延在方向を芯線接続部36の延在方向に沿わせた姿勢で、芯線接続部36に接続されている。このため、端子30端子本体部32に対して交差する方向に電線22を引出すことができる。これにより、端子本体部32の延長上に、車両の周辺部品が存在し、電線22を引出すことが困難となるような場合に、電線を、車両の周辺部品との干渉を避けて好ましい方向に引出すことができる。   According to the terminal-equipped electric wire 20 and the terminal 30 configured as described above, the core wire connecting portion 36 is bent so as to intersect the terminal main body portion 32, and the exposed core wire portion 24 a of the electric wire 22 is extended. It is connected to the core wire connection portion 36 in a posture in which the direction is along the extending direction of the core wire connection portion 36. For this reason, the electric wire 22 can be pulled out in a direction crossing the terminal 30 and the terminal main body 32. Thus, when there are peripheral parts of the vehicle on the extension of the terminal main body 32 and it is difficult to pull out the electric wires 22, the electric wires are directed in a preferable direction while avoiding interference with the peripheral parts of the vehicle. Can be withdrawn.

また、芯線接続部36の少なくとも一部が端子本体部32の少なくとも一部に被さるように、芯線接続部36が端子本体部32に対して折曲げられているため、端子30のコンパクト化が可能となる。例えば、L字状の端子と比較すると、本端子30の幅方向寸法は、平面視において、芯線接続部36が端子本体部32に対して重複している分、小さくなり、コンパクト化が実現されている。   Further, since the core wire connection part 36 is bent with respect to the terminal body part 32 so that at least a part of the core wire connection part 36 covers at least a part of the terminal body part 32, the terminal 30 can be made compact. It becomes. For example, as compared with an L-shaped terminal, the width-direction dimension of the terminal 30 is smaller because the core wire connection portion 36 overlaps the terminal main body portion 32 in a plan view, thereby realizing compactness. ing.

特に、芯線接続部36の少なくとも一部が端子本体部32の少なくとも一部に対して間隔をあけて重なるように、芯線接続部36が端子本体部32に対して折返されているため、端子30の厚みを可及的に小さくして、端子30をより小型化できる。   In particular, since the core wire connection portion 36 is folded back with respect to the terminal body portion 32 so that at least a portion of the core wire connection portion 36 overlaps at least a portion of the terminal body portion 32 with a space therebetween, the terminal 30 The terminal 30 can be made smaller by reducing the thickness of the terminal 30 as much as possible.

もっとも、芯線接続部36の少なくとも一部が端子本体部32の少なくとも一部に対して間隔をあけて重なっていることは必須ではない。例えば、図3に示す第1変形例に係る端子付電線20Bのように、端子30Bの芯線接続部36に対応する芯線接続部36Bが、端子本体部32に対して180度よりも小さい角度をなすように曲げられ、芯線接続部36Bが、端子本体部32に対して斜めに傾く姿勢とされていてもよい。この場合でも、芯線接続部36Bの少なくとも一部が、端子本体部32の少なくとも一部に対して被さっているため、端子本体部32を平面視した状態において、芯線接続部36Bと端子本体部32とが部分的に重複する。このため、端子30Bの小型化が図られている。   However, it is not essential that at least a part of the core wire connection part 36 overlaps at least a part of the terminal main body part 32 with a gap. For example, like the electric wire with terminal 20B according to the first modification shown in FIG. 3, the core wire connecting portion 36B corresponding to the core wire connecting portion 36 of the terminal 30B has an angle smaller than 180 degrees with respect to the terminal main body portion 32. The core wire connection part 36 </ b> B may be bent so as to be inclined with respect to the terminal main body part 32. Even in this case, since at least a part of the core wire connection part 36B covers at least a part of the terminal main body part 32, the core wire connection part 36B and the terminal main body part 32 are viewed in a state in which the terminal main body part 32 is viewed in plan. And partially overlap. For this reason, size reduction of the terminal 30B is achieved.

また、芯線接続部36は、端子本体部32に対して直交するように折曲げられているため、電線22を端子本体部32に対して直交する横方向に引出すことができる。   Further, since the core wire connecting portion 36 is bent so as to be orthogonal to the terminal main body portion 32, the electric wire 22 can be pulled out in a lateral direction orthogonal to the terminal main body portion 32.

もっとも、端子本体部を平面視した状態において、芯線接続部は、端子本体部に対して斜め方向に延出する姿勢で、曲げられていてもよい。これにより、電線を端子本体部に対して斜め方向に引出すことができる。   But in the state which planarly viewed the terminal main-body part, the core wire connection part may be bent by the attitude | position extended in the diagonal direction with respect to the terminal main-body part. Thereby, an electric wire can be pulled out in the diagonal direction with respect to a terminal main-body part.

また、端子本体部32にはボルト挿通孔33hが形成されているため、端子本体部32をボルト締めすることによって、端子30を固定することが可能となる。   Further, since the terminal body portion 32 is formed with a bolt insertion hole 33h, the terminal 30 can be fixed by tightening the terminal body portion 32 with a bolt.

なお、ここでは、端子30がアース端子である例で説明したが、ボルト挿通孔が形成された端子としては、その他、バッテリーへの接続用の端子、オルタネーターへの接続用の端子等が考えられる。   Here, the example in which the terminal 30 is a ground terminal has been described. However, as a terminal in which a bolt insertion hole is formed, a terminal for connection to a battery, a terminal for connection to an alternator, and the like are conceivable. .

図4及び図5は、本実施形態を前提とする第2変形例に係る端子付電線20Cを示している。   4 and 5 show a terminal-attached electric wire 20C according to a second modification based on the present embodiment.

この端子付電線20Cの端子30Cが上記端子30と異なるのは次の点である。   The terminal 30C of the electric wire with terminal 20C is different from the terminal 30 in the following points.

すなわち、芯線接続部36に対応する芯線接続部36Cは、芯線接続部36よりも長く形成され、その先端部が端子本体部32の側方に突出している。   That is, the core wire connection portion 36 </ b> C corresponding to the core wire connection portion 36 is formed longer than the core wire connection portion 36, and the tip end portion protrudes to the side of the terminal main body portion 32.

芯線接続部36Cの先端部の両側部に一対の被覆圧着片36Caが形成されている。一対の被覆圧着片36Caは、細帯状に形成されている。   A pair of coated crimping pieces 36Ca are formed on both side portions of the distal end portion of the core wire connecting portion 36C. The pair of covering pressure-bonding pieces 36Ca is formed in a narrow strip shape.

また、電線22の露出芯線部24aが芯線接続部36Cに接続された状態で、被覆部26の先端部は、芯線接続部36Cの先端部であって、一対の被覆圧着片36Ca間に位置している。そして、一対の被覆圧着片36Caが被覆部26の先端部の外周囲に抱持状にカシメられている。   Further, in a state where the exposed core wire portion 24a of the electric wire 22 is connected to the core wire connecting portion 36C, the tip portion of the covering portion 26 is a tip portion of the core wire connecting portion 36C and is positioned between the pair of covered crimping pieces 36Ca. ing. A pair of covering crimping pieces 36 </ b> Ca are caulked around the outer periphery of the distal end portion of the covering portion 26.

また、チューブ40は、芯線接続部36Cのうち露出芯線部24aよりも先端側の部分から、芯線接続部36Cと露出芯線部24aとの接続部37、一対の被覆圧着片36Caを経て、芯線接続部36Cの外方位置において被覆部26の外周囲の部分を覆っている。   Further, the tube 40 is connected to the core wire from a portion of the core wire connecting portion 36C on the tip side of the exposed core wire portion 24a through the connecting portion 37 between the core wire connecting portion 36C and the exposed core wire portion 24a and a pair of coated crimping pieces 36Ca. The outer peripheral portion of the covering portion 26 is covered at an outer position of the portion 36C.

この変形例によると、一対の被覆圧着片36Caによって被覆部26を保持しているため、端子30Cと電線22との接続強度を高めることができる。   According to this modification, since the covering portion 26 is held by the pair of covering pressure-bonding pieces 36Ca, the connection strength between the terminal 30C and the electric wire 22 can be increased.

{第2実施形態}
第2実施形態に係る端子付電線及び端子について説明する。図6は端子付電線120を示す概略平面図であり、図7は端子付電線120がコネクタハウジング210に組込まれた状態を示す説明図である。なお、本実施形態の説明において、上記第1実施形態で説明したものと同様構成要素については同一符号を付してその説明を省略する。
{Second Embodiment}
The electric wire with terminal and the terminal according to the second embodiment will be described. FIG. 6 is a schematic plan view showing the terminal-attached electric wire 120, and FIG. 7 is an explanatory view showing a state where the terminal-attached electric wire 120 is assembled in the connector housing 210. In the description of the present embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

この端子付電線120の端子130が第1実施形態で説明した端子30と異なるのは、端子本体部132が端子接続部134を含む点である。   The terminal 130 of the terminal-attached electric wire 120 is different from the terminal 30 described in the first embodiment in that the terminal main body portion 132 includes a terminal connection portion 134.

すなわち、上記端子本体部32に対応する端子本体部132は、長尺状に形成され、その一端部に平板状の基部133が設けられると共に,その他端部に端子接続部134が設けられている。基部133と端子接続部134とは直線状に繋がっている。基部133に対して、上記第1実施形態と同様に芯線接続部36が設けられている。   That is, the terminal main body portion 132 corresponding to the terminal main body portion 32 is formed in an elongated shape, a flat plate-like base portion 133 is provided at one end thereof, and a terminal connection portion 134 is provided at the other end portion. . The base part 133 and the terminal connection part 134 are connected linearly. A core wire connecting portion 36 is provided for the base portion 133 as in the first embodiment.

端子接続部134は、相手側端子200と接続可能な形状に形成されている。ここでは、端子接続部134は、筒形状(ここでは角筒形状)に形成されており、タブ状又はピン状の相手側端子200を挿入接続できるようになっている。すなわち、ここでは、端子接続部134は、いわゆるメス端子形状に形成され、相手側端子200であるオス端子を挿入接続可能に構成されている。端子接続部は、タブ状又はピン状に形成されたもの、すなわち、オス端子形状に形成されていてもよい。   The terminal connection part 134 is formed in a shape that can be connected to the mating terminal 200. Here, the terminal connection part 134 is formed in a cylindrical shape (here, a rectangular tube shape) so that a tab-like or pin-like counterpart terminal 200 can be inserted and connected. That is, here, the terminal connection part 134 is formed in a so-called female terminal shape, and is configured so that a male terminal which is the counterpart terminal 200 can be inserted and connected. The terminal connecting portion may be formed in a tab shape or a pin shape, that is, in a male terminal shape.

上記端子接続部134は、コネクタハウジング210のキャビティ212内に収容可能に構成されている。   The terminal connection portion 134 is configured to be housed in the cavity 212 of the connector housing 210.

すなわち、図7に示すように、コネクタハウジング210は、樹脂等によって形成された部材であり、複数のキャビティ212が形成されている。ここでは、複数(2つ)のキャビティ212が縦に並ぶように形成されている。なお、図7では、1つのキャビティ212にのみ端子130がセットされた状態を示している。   That is, as shown in FIG. 7, the connector housing 210 is a member formed of resin or the like, and a plurality of cavities 212 are formed. Here, a plurality (two) of cavities 212 are formed so as to be arranged vertically. FIG. 7 shows a state in which the terminal 130 is set only in one cavity 212.

キャビティ212は、端子130を収容可能な孔形状、ここでは、角孔状に形成されている。キャビティ212は、コネクタハウジング210の前後に開口しており、キャビティ212の後方開口から本端子付電線120の端子130をキャビティ212に挿入して収容できる。なお、キャビティ212内には、端子接続部134を位置決め保持する係合部材(ランス等と呼ばれる)等が形成されており、端子130はキャビティ212内に一定位置で保持される。また、キャビティ212の前方開口を通じて、相手側コネクタに保持された相手側端子200が本端子接続部134に接続される。   The cavity 212 is formed in a hole shape that can accommodate the terminal 130, in this case, a square hole shape. The cavity 212 opens at the front and rear of the connector housing 210, and the terminal 130 of the terminal-attached electric wire 120 can be inserted into the cavity 212 from the rear opening of the cavity 212 and can be accommodated. An engagement member (called a lance or the like) for positioning and holding the terminal connecting portion 134 is formed in the cavity 212, and the terminal 130 is held in a fixed position in the cavity 212. Further, the counterpart terminal 200 held by the counterpart connector is connected to the terminal connection portion 134 through the front opening of the cavity 212.

また、コネクタハウジング210のうちキャビティ212の後方側部分の一側には、開口部213が形成されている。そして、端子付電線120の端子130を本キャビティ212にセットすると、芯線接続部36に接続された電線22が当該開口部213を通ってコネクタハウジング210の側方に引出される。   In addition, an opening 213 is formed on one side of the rear side portion of the cavity 212 in the connector housing 210. When the terminal 130 of the terminal-attached electric wire 120 is set in the main cavity 212, the electric wire 22 connected to the core wire connecting portion 36 is pulled out to the side of the connector housing 210 through the opening 213.

このように、端子の端子本体部は、ボルト締固定される構成である必要はなく、本実施形態のような、相手側端子と接続される端子形状であってもよい。   Thus, the terminal main body portion of the terminal does not need to be configured to be bolted and fixed, and may have a terminal shape that is connected to the counterpart terminal as in the present embodiment.

本実施形態によると、ボルト締固定される構成に関する作用効果を除いて、上記第1実施形態と同様の作用効果を得ることができる。   According to the present embodiment, the same functions and effects as those of the first embodiment can be obtained, except for the functions and effects related to the bolted and fixed configuration.

特に、本実施形態によると、電線22と端子130との接続部37をチューブ40で覆いつつ、電線22をコネクタハウジング210の側方に引出すことが可能となる。このため、コネクタハウジング210の設置箇所後方に車両の周辺部品等が存在する場合でも、当該周辺部品との干渉を避けつつ、電線22を引出すことが可能となり、コネクタの配設スペースを削減することが可能となる。   In particular, according to the present embodiment, the electric wire 22 can be pulled out to the side of the connector housing 210 while the connecting portion 37 between the electric wire 22 and the terminal 130 is covered with the tube 40. For this reason, even when there are peripheral parts of the vehicle behind the installation location of the connector housing 210, the electric wires 22 can be pulled out while avoiding interference with the peripheral parts, and the connector installation space can be reduced. Is possible.
