Description

本発明は、主にアルミ電線との接続に用いて好適な圧着端子に関するものである。 The present invention relates to a crimp terminal suitable mainly for use in connection with an aluminum electric wire.

この種の圧着端子として、図８及び図９に示すものが知られている（例えば、特許文献１、２参照）。 As this type of crimp terminal, those shown in FIGS. 8 and 9 are known (see, for example, Patent Documents 1 and 2).

図８に示すように、この圧着端子１は、図示しないボルト等の締結手段が貫通可能な貫通孔２ａを有した電気接触部２と、アルミ電線５の複数本のアルミ素線６ａを撚り合わせてなる導体（芯線）６に圧着して接続される断面略Ｕ字状の圧着部３とを備えている。この圧着部３の内面３ａには、導体６の長さ方向に対して直交する方向に延びる複数本（図示例では３本）の凹溝状のセレーション４が形成されている。 As shown in FIG. 8, this crimp terminal 1 is formed by twisting together an electrical contact portion 2 having a through hole 2a through which a fastening means such as a bolt (not shown) can pass, and a plurality of aluminum wires 6a of an aluminum electric wire 5. And a crimping portion 3 having a substantially U-shaped cross section connected to the conductor (core wire) 6 by crimping. A plurality of (three in the illustrated example) concave groove-shaped serrations 4 extending in a direction orthogonal to the length direction of the conductor 6 are formed on the inner surface 3 a of the crimping portion 3.

そして、図９に示すように、圧着端子１の圧着部３にアルミ電線５の導体６を加締めにより圧着すると、導体６のアルミ素線６ａが、凹溝状のセレーション４に擦り付けられつつ摺動することで、導体６のアルミ素線６ａの表面の酸化皮膜が破壊され、露出した新生面（素地）と圧着端子１の圧着部３との間に凝着（固体同士の接触面で互いの表面の原子が及ぼし合う結合力により固体同士がくっつく現象）が起こり、電気接続が達成されるようになっている。 Then, as shown in FIG. 9, when the conductor 6 of the aluminum electric wire 5 is crimped to the crimping portion 3 of the crimp terminal 1 by crimping, the aluminum strand 6a of the conductor 6 is slid while being rubbed against the concave serration 4 By moving, the oxide film on the surface of the aluminum element wire 6a of the conductor 6 is destroyed, and adhesion between the exposed new surface (substrate) and the crimping part 3 of the crimping terminal 1 (in the contact surface between solids, A phenomenon in which solids stick to each other due to the bonding force exerted by atoms on the surface occurs, and electrical connection is achieved.

図１０（ａ）は前記圧着端子の展開図、図１０（ｂ）は図１０（ａ）のＢ−Ｂ線に沿った断面図、図１０（ｃ）は圧着時にセレーションに対する電線の摺動により凝着が起こることを示す説明用の断面図である。 10A is a development view of the crimp terminal, FIG. 10B is a cross-sectional view taken along line BB in FIG. 10A, and FIG. 10C is a result of sliding of the electric wire with respect to the serration during crimping. It is sectional drawing for description which shows that adhesion occurs.

各セレーション４は、導体６の長さ方向に直交する方向に互いに平行に延びており、導体６の圧着時には、導体６と端子１が伸びる際の相対摺動により凝着が発生する。凝着発生箇所を図中Ｐで示す。 The serrations 4 extend in parallel to each other in a direction perpendicular to the length direction of the conductor 6, and when the conductor 6 is crimped, adhesion occurs due to relative sliding when the conductor 6 and the terminal 1 extend. The adhesion occurrence location is indicated by P in the figure.

特開２００７−１７３２１５号公報（図１）Japanese Patent Laying-Open No. 2007-173215 (FIG. 1) 特開２００３−２４９２８４号公報（図７）Japanese Patent Laying-Open No. 2003-249284 (FIG. 7)

ところで、上述した従来の圧着端子１のように、導体６の長さ方向（軸方向）と直交する方向に延びるセレーション４だけしか導体圧着部３の内面に設けられていないと、電線５の伸びは、主に導体６の長さ方向にだけ発生し、それと直交する方向（導体の径方向または周方向）にはあまり発生しない。しかも、その伸びは、図１０（ｃ）に矢印の長さで区別して示すように、中央のセレーション４ではあまり発生せず、両端のセレーション４において発生する。その結果、凝着発生箇所Ｐが、主に軸方向の特に３本あるセレーション４の両端のセレーション４の外側に限られてしまい、全体の凝着面積が少なくなり、電気的接続性能が低くなってしまうという問題があった。 By the way, if only the serration 4 extending in the direction orthogonal to the length direction (axial direction) of the conductor 6 is provided on the inner surface of the conductor crimping portion 3 as in the conventional crimp terminal 1 described above, the extension of the electric wire 5 Is mainly generated only in the length direction of the conductor 6 and is not so much generated in a direction perpendicular to the conductor (radial direction or circumferential direction of the conductor). Moreover, as shown in FIG. 10C by distinguishing the lengths of the arrows, the elongation does not occur so much in the central serration 4 but occurs in the serrations 4 at both ends. As a result, the adhesion occurrence point P is mainly limited to the outside of the serrations 4 at both ends of the three serrations 4 in the axial direction, the entire adhesion area is reduced, and the electrical connection performance is lowered. There was a problem that.

本発明は、上記事情を考慮し、凝着面積を増やして、電気的接続性能を向上させることのできる圧着端子を提供することを目的とする。 In view of the above circumstances, an object of the present invention is to provide a crimp terminal capable of increasing an adhesion area and improving electrical connection performance.

上記課題を解決するために、請求項１の発明は、電気接続部の直後に、電線の導体の端末に圧着して接続される導体圧着部が設けられ、該導体圧着部が、前記電気接続部から連続する底板と、該底板の左右両側に延設されて該底板の内面上に配された前記導体を包むように加締められる左右一対の導体加締片とで断面略Ｕ字状に形成され、該導体圧着部の内面に、前記導体の長さ方向に対して直交する方向に延びる凹溝状のセレーションが形成された圧着端子において、前記導体の長さ方向に対して直交する方向に延びるセレーションを第１のセレーションとした場合、該第１のセレーションが、前記導体圧着部の内面の前記導体の長さ方向における前後両端に設けられると共に、それら前後両端の第１のセレーションの間の領域の前記導体圧着部の内面に、前記導体の長さ方向に沿って延びる第２のセレーションが、前記導体の長さ方向に対して直交する方向に間隔をおいて複数本設けられていることを特徴とする。 In order to solve the above problems, the invention of claim 1 is provided with a conductor crimping portion that is crimped and connected to a terminal of a conductor of an electric wire immediately after the electrical connection portion, and the conductor crimping portion is connected to the electrical connection. Formed in a substantially U-shaped cross-section with a bottom plate continuous from the section and a pair of left and right conductor crimping pieces that are extended on both the left and right sides of the bottom plate and are crimped so as to wrap the conductor disposed on the inner surface of the bottom plate In a crimp terminal in which a concave groove-shaped serration extending in a direction perpendicular to the length direction of the conductor is formed on the inner surface of the conductor crimp portion, in a direction perpendicular to the length direction of the conductor When the extended serration is the first serration, the first serration is provided at both front and rear ends in the length direction of the conductor on the inner surface of the conductor crimping portion, and between the first serrations at the front and rear ends. Said conductor of the region A plurality of second serrations extending along the length direction of the conductor are provided on the inner surface of the landing portion at intervals in a direction orthogonal to the length direction of the conductor. .

請求項２の発明は、請求項１に記載の圧着端子であって、前記第１のセレーションが、前記底板の内面から左右の導体加締片の内面の先端の手前まで連続して形成され、前記第２のセレーションが、前記第１のセレーションの長さの範囲に略均等に分散して配置されていることを特徴とする。 The invention of claim 2 is the crimp terminal according to claim 1, wherein the first serration is continuously formed from the inner surface of the bottom plate to the front of the inner surfaces of the left and right conductor crimping pieces, The second serrations are arranged so as to be substantially evenly distributed in the range of the length of the first serrations.

請求項１の発明によれば、導体の軸方向に沿って配置された第２のセレーションの存在により、軸方向に直交する方向に電線の導体が伸びるようになり、導体圧着部全体で凝着が発生するようになる。これにより、凝着面積が拡大して、電気的接続性能が向上する。特に、軸方向に沿って延びる第２のセレーションを設けた領域を、導体圧着部の内面の前後両端に設けた、導体の軸方向と直交する方向に延びる第１のセレーションで挟んでいるので、その両端の第１のセレーションで挟まれた領域の導体の伸び方向を、第１のセレーションによって規制することができ、導体をその軸方向と直交する方向に効率的に伸びるようにすることができる。従って、第２のセレーションのエッジを起点にしての凝着を効率よく起こさせることができるようになり、凝着面積の拡大が図れる。 According to the first aspect of the present invention, due to the presence of the second serration arranged along the axial direction of the conductor, the conductor of the electric wire extends in a direction perpendicular to the axial direction, and the entire conductor crimping portion is adhered. Will occur. Thereby, the adhesion area is expanded and the electrical connection performance is improved. In particular, since the region provided with the second serration extending along the axial direction is sandwiched between the first serrations provided in the front and rear ends of the inner surface of the conductor crimping portion and extending in the direction perpendicular to the axial direction of the conductor, The extension direction of the conductor in the region sandwiched between the first serrations at both ends can be regulated by the first serration, and the conductor can be efficiently extended in a direction perpendicular to the axial direction. . Therefore, the adhesion starting from the edge of the second serration can be efficiently caused, and the adhesion area can be expanded.

請求項２の発明によれば、導体圧着部の内面の導体に接する部分のほぼ全面にセレーションを設けることになるので、導体圧着部の全体を導体と凝着させることができ、電気的接続性能の大幅な向上が図れる。 According to the invention of claim 2, since serration is provided on almost the entire surface of the inner surface of the conductor crimping portion in contact with the conductor, the entire conductor crimping portion can be adhered to the conductor, and the electrical connection performance Can be greatly improved.

FIG. 3B is a developed view of the crimping part, FIG. 3B is a sectional view taken along the line B-B in FIG. 3A, and FIG. 3C is a sectional view taken along the line C-C in FIG.

図１および図２に示すように、この圧着端子１０は、全体が銅または銅合金でプレス加工された上に錫メッキが施されることにより製作されており、前部に電気接続部１１を有し、その直後に、アルミ電線Ｗ（以下、単に電線という）のアルミ導体Ｗａ（以下、単に導体と言う）の端末に圧着して接続される導体圧着部１２、その更に後側に、電線Ｗの被覆Ｗｂ付の部分を加締める被覆加締部１５を有している。 As shown in FIGS. 1 and 2, the crimp terminal 10 is manufactured by being subjected to tin plating after being entirely pressed with copper or a copper alloy. Immediately after that, the conductor crimping portion 12 that is crimped and connected to the end of an aluminum conductor Wa (hereinafter simply referred to as a conductor) of an aluminum wire W (hereinafter simply referred to as a wire), A covering caulking portion 15 for caulking a portion of W with the covering Wb is provided.

アルミ電線Ｗは、アルミニウム製またはアルミニウム合金製の複数本のアルミ素線Ｗｃを撚り合わせてなる導体（芯線）Ｗａと、この導体Ｗａを被覆する絶縁被覆Ｗｂとで構成されており、圧着端子１０は、アルミ電線Ｗの導体Ｗａの端末（前端）に、その前後方向を電線Ｗの導体Ｗａの長手方向と一致させて接続される。 The aluminum electric wire W is composed of a conductor (core wire) Wa formed by twisting a plurality of aluminum wires Wc made of aluminum or aluminum alloy, and an insulation coating Wb covering the conductor Wa. Is connected to the end (front end) of the conductor Wa of the aluminum electric wire W such that its front-rear direction coincides with the longitudinal direction of the conductor Wa of the electric wire W.

導体圧着部１２は、電気接続部１１から連続する底板１３と、底板１３の左右両側に延設されて底板１３の内面１３ａ上に配された導体Ｗａを包むように加締められる左右一対の導体加締片１４、１４とで断面略Ｕ字状に形成されている。 The conductor crimping portion 12 includes a pair of left and right conductors that are crimped so as to wrap around the bottom plate 13 that is continuous from the electrical connection portion 11 and the conductor Wa that is provided on the left and right sides of the bottom plate 13 and is disposed on the inner surface 13a of the bottom plate 13. The fastening pieces 14 and 14 are formed in a substantially U-shaped cross section.

この導体圧着部１２の内面、即ち、底板１３の内面１３ａから導体加締片１４の内面１４ａにかけての範囲には、導体Ｗａの長さ方向に対して直交する方向（導体の径方向または周方向に相当するので、以下においてはそのように言うこともある）に延びる凹溝状の第１のセレーション１６と、導体Ｗａの長さ方向に沿って互いに平行に延びる第２のセレーション１７とが設けられている。 In the range from the inner surface of the conductor crimping portion 12, that is, the inner surface 13 a of the bottom plate 13 to the inner surface 14 a of the conductor crimping piece 14, a direction orthogonal to the length direction of the conductor Wa (the radial direction or circumferential direction of the conductor) Therefore, the first serration 16 having a groove shape extending in the following manner and the second serration 17 extending in parallel with each other along the length direction of the conductor Wa are provided. It has been.

この場合、第１のセレーション１６は、導体圧着部１２の内面の導体Ｗａの長さ方向における前後両端に、底板１３の内面１３ａから左右の導体加締片１４の内面１４ａの先端の手前まで連続して形成されている。また、第２のセレーション１７は、それら前後両端の第１のセレーション１６の間の領域の導体圧着部１２の内面に、第１のセレーション１６の長さの範囲に略均等に分散して、つまり、導体Ｗａの長さ方向に対して直交する方向に等しい間隔をおいて複数本設けられている。 In this case, the first serration 16 is continuous from the inner surface 13a of the bottom plate 13 to the front of the inner surface 14a of the left and right conductor crimping pieces 14 at both front and rear ends in the length direction of the conductor Wa on the inner surface of the conductor crimping portion 12. Is formed. Further, the second serrations 17 are distributed substantially evenly in the range of the length of the first serrations 16 on the inner surface of the conductor crimping portion 12 in the region between the first serrations 16 at the front and rear ends. A plurality of conductors are provided at equal intervals in a direction orthogonal to the length direction of the conductor Wa.

次に作用を説明する。 Next, the operation will be described.

このように構成された圧着端子１０の圧着部１２の底板１３の上に、アルミ電線Ｗの端末を皮剥きして露出させた導体Ｗａを載せて、図４に示すように、一対の導体加締片１４、１４を導体Ｗａを包むように加締めて圧着すると、図５に示すように、外部から加えられる押圧力により、導体圧着部１２の内面と導体Ｗａが強く圧接して、圧着端子１０および導体Ｗａが導体Ｗａの長手方向に伸びる。 On the bottom plate 13 of the crimping portion 12 of the crimping terminal 10 configured in this manner, the conductor Wa exposed by peeling off the end of the aluminum electric wire W is placed, and as shown in FIG. When the clamping pieces 14 and 14 are crimped so as to enclose the conductor Wa and are crimped, the inner surface of the conductor crimping portion 12 and the conductor Wa are strongly pressed by the pressing force applied from the outside, as shown in FIG. The conductor Wa extends in the longitudinal direction of the conductor Wa.

その際、セレーション１６、１７のエッジに導体Ｗａの素線Ｗｃが擦れながら矢印のように摺動することにより、素線Ｗｃの表面の酸化皮膜が破壊されて、その新生面（素地）が露出する。そして、その新生面と導体圧着部１２の内面とが凝着を起こすことで、導体圧着部１２に導体Ｗａが良好な状態で電気接続される。 At that time, the wire Wc of the conductor Wa slides as indicated by an arrow while rubbing the edges of the serrations 16 and 17, thereby destroying the oxide film on the surface of the wire Wc and exposing the new surface (substrate). . Then, the newly formed surface and the inner surface of the conductor crimping portion 12 cause adhesion, whereby the conductor Wa is electrically connected to the conductor crimping portion 12 in a good state.

同時に、図６に示すように、導体Ｗａの軸方向に沿って配置された第２のセレーション１７の存在により、軸方向に直交する方向Ｙに導体Ｗａ（素線Ｗｃ）が伸びるようになり、導体圧着部１２全体で凝着が発生するようになる。これにより、凝着面積が拡大して、電気的接続性能が向上する。特に、軸方向に沿って延びる第２のセレーション１７を設けた領域を、図５に示すように、導体圧着部１２の内面の前後両端に設けた、導体Ｗａの軸方向と直交する方向に延びる第１のセレーション１６で挟んでいるので、その両端の第１のセレーション１６で挟まれた領域の導体Ｗａの伸び方向を、第１のセレーション１６によって規制することができ、導体Ｗａをその軸方向と直交する方向に効率的に伸びるようにすることができる。従って、図６に示すように、第２のセレーション１７のエッジＥＧを起点にしての凝着（凝着箇所を図中Ｐで示す）を効率よく起こさせることができるようになり、凝着面積の拡大が図れる。 At the same time, as shown in FIG. 6, due to the presence of the second serrations 17 arranged along the axial direction of the conductor Wa, the conductor Wa (wire Wc) extends in the direction Y perpendicular to the axial direction. Adhesion occurs in the entire conductor crimping portion 12. Thereby, the adhesion area is expanded and the electrical connection performance is improved. In particular, the region provided with the second serrations 17 extending along the axial direction extends in a direction orthogonal to the axial direction of the conductor Wa provided at the front and rear ends of the inner surface of the conductor crimping portion 12 as shown in FIG. Since it is sandwiched between the first serrations 16, the extension direction of the conductor Wa in the region sandwiched between the first serrations 16 at both ends can be regulated by the first serration 16, and the conductor Wa can be controlled in its axial direction. It can be made to extend efficiently in the direction orthogonal to. Therefore, as shown in FIG. 6, it is possible to efficiently cause the adhesion (the adhesion point is indicated by P in the figure) starting from the edge EG of the second serration 17. Can be expanded.

この場合、図７に示すように、導体圧着部１２の内面の導体に接する部分のほぼ全面に第１、第２のセレーション１６、１７を設けているので、導体圧着部１２の全体を導体Ｗａと効率よく凝着させることができ、電気的接続性能の大幅な向上が図れる。 In this case, as shown in FIG. 7, the first and second serrations 16 and 17 are provided on almost the entire surface of the inner surface of the conductor crimping portion 12 in contact with the conductor. It is possible to effectively adhere to each other, and the electrical connection performance can be greatly improved.

なお、図６に示すように、凹部１７ａと凸部１７ｂの間隔（特に凹部１７ａの長さ）は、素線Ｗｃの径よりも僅かに小さい方が、素線Ｗｃとの引っ掛かりをエッジＥＧで捕らえやすくなるので好ましい。 As shown in FIG. 6, the distance between the concave portion 17a and the convex portion 17b (especially the length of the concave portion 17a) is slightly smaller than the diameter of the strand Wc. Since it becomes easy to catch, it is preferable.

また、上記実施形態においては、本発明の圧着端子をアルミ電線Ｗに接続する場合について述べたが、銅電線に接続しても同様の効果を発揮することができる。 Moreover, in the said embodiment, although the case where the crimp terminal of this invention was connected to the aluminum electric wire W was described, even if it connects to a copper electric wire, the same effect can be exhibited.
