Description

本発明は、電線に接続する圧着端子に関する。   The present invention relates to a crimp terminal connected to an electric wire.

この種の従来の圧着端子として、特許文献１に開示されたものがある。図６及び図７に示すように、圧着端子１１０を接続する電線Ｗは、複数の素線１０１ａからなる芯線１０１と芯線１０１の外周を覆う絶縁外皮１０２とから構成されている。電線Ｗの先端側は、絶縁外皮１０２が除去されて芯線１０１が露出されている。 A conventional crimp terminal of this type is disclosed in Patent Document 1. As shown in FIGS. 6 and 7, the electric wire W connecting the crimp terminal 110 includes a core wire 101 composed of a plurality of strands 101 a and an insulating sheath 102 covering the outer periphery of the core wire 101. At the tip end side of the electric wire W, the insulating sheath 102 is removed and the core wire 101 is exposed.

圧着端子１１０は、相手端子接続部１１１と電線接続部１１５を有する。電線接続部１１５は、芯線圧着部１１６と外皮圧着部１１７を有する。芯線圧着部１１６は、基底部１１６ａとこの基底部１１６ａの両側から延設された一対の加締め片部１１６ｂを有する。芯線圧着部１１６の基底部１１６ａと一対の加締め片部１１６ｂの内面には、セレーション１１８が形成されている。セレーション１１８は、三本の長溝である。外皮圧着部１１７は、基底部１１７ａとこの基底部１１７ａの両側から延設された一対の加締め片部１１７ｂを有する。   The crimp terminal 110 has a mating terminal connection portion 111 and a wire connection portion 115. The wire connection portion 115 includes a core wire crimping portion 116 and an outer skin crimping portion 117. The core wire crimping part 116 has a base part 116a and a pair of caulking piece parts 116b extending from both sides of the base part 116a. A serration 118 is formed on the inner surface of the base portion 116a of the core wire crimping portion 116 and the pair of caulking piece portions 116b. The serration 118 is three long grooves. The outer skin crimping part 117 has a base part 117a and a pair of caulking piece parts 117b extending from both sides of the base part 117a.

圧着端子１１０は、芯線圧着部１１６によって露出された芯線１０１を加締め圧着し、外皮圧着部１１７によって絶縁外皮１０２を加締め圧着している。   The crimp terminal 110 crimps and crimps the core wire 101 exposed by the core wire crimping portion 116, and crimps and crimps the insulating sheath 102 by the outer skin crimping portion 117.

ところで、加締め圧着は、図８（ａ）、（ｂ）に示すようなワイヤクリンパ１２０を使用する。ワイヤクリンパ１２０は、その加締め先端側に最終的な加締め外周形状の加締め溝１２１を有する。図９（ａ）、（ｂ）に示すように、ワイヤクリンパ１２０で一対の加締め片部１１６ｂを押圧し、一対の加締め片部１１６ｂを塑性変形することにより行う。   By the way, the crimping crimp uses a wire crimper 120 as shown in FIGS. The wire crimper 120 has a caulking groove 121 having a final caulking outer peripheral shape on the caulking tip side. As shown in FIGS. 9A and 9B, the pair of crimping pieces 116b are pressed by the wire crimper 120 and the pair of crimping pieces 116b are plastically deformed.

上記した加締め過程では、加締め片部１１６ｂより芯線１０１が圧着力を受ける。すると、図９（ｂ）に示すように、芯線１０１が左右いずれの方向（ａ矢印方向、ｂ矢印方向）にも自由に伸びることができる。一般的には、加締め片部１１６ｂの先端側に位置する芯線１０１は、先端側（ａ矢印方向）に伸び、加締め片部１１６ｂの後端側（絶縁外皮側）に位置する芯線１０１は、後端側（絶縁外皮側）（ｂ矢印方向）に伸びる。   In the above caulking process, the core wire 101 receives a crimping force from the caulking piece portion 116b. Then, as shown in FIG. 9B, the core wire 101 can freely extend in either the left or right direction (a arrow direction, b arrow direction). Generally, the core wire 101 located on the distal end side of the crimping piece portion 116b extends to the distal end side (a arrow direction), and the core wire 101 located on the rear end side (insulating outer skin side) of the crimping piece portion 116b is , And extends to the rear end side (insulating skin side) (in the direction of arrow b).

このように芯線１０１が自由に伸び、縮径するため、圧着力が有効に芯線１０１の各素線１０１ａに作用しないため、素線１０１ａは低い圧縮力しか受けられず、凝着を有効に発生させることができない。凝着が発生しない、若しくは、凝着が不足すると、素線１０１ａ間の導通を確保できず、回路全体の抵抗を高くなるという問題があった。   Since the core wire 101 freely expands and contracts in this way, the crimping force does not effectively act on each strand 101a of the core wire 101, so the strand 101a can receive only a low compressive force and effectively generate adhesion. I can't let you. If adhesion does not occur or if adhesion is insufficient, there is a problem that conduction between the strands 101a cannot be ensured and the resistance of the entire circuit increases.

そこで、本発明は、前記した課題を解決すべくなされたものであり、芯線の素線間の導通を確実に確保でき、回路全体の抵抗を低減できる圧着端子を提供することを目的とする。   Therefore, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a crimp terminal that can reliably ensure conduction between the core wires and can reduce the resistance of the entire circuit.

本発明は、電線の複数の素線からなる芯線を加締め圧着する芯線圧着部（１６）を有する圧着端子であって、前記芯線圧着部は、前記芯線の軸方向の間隔を置いた複数箇所に他の箇所よりも強く加締めた強圧着部が設けられ、且つ、複数の前記強圧着部は、前記芯線の軸方向に交互に異なる対向位置を強く加締めて設けられたことを特徴とする圧着端子である。   The present invention is a crimp terminal having a core wire crimping portion (16) for crimping and crimping a core wire composed of a plurality of strands of an electric wire, wherein the core wire crimp portion is provided at a plurality of locations spaced in the axial direction of the core wire. And a plurality of the strong pressure-bonding portions are provided by strongly crimping different opposing positions alternately in the axial direction of the core wire. This is a crimp terminal.

前記複数の強圧着部は、３箇所であるものを含む。   The plurality of strong pressure-bonding portions include those having three locations.

本発明によれば、芯線圧着部内の芯線には、全域に圧縮力が作用すると共に、３箇所で強い圧縮力が作用するため、より多くの凝着が発生し、素線間の導通を確実に確保でき、回路全体の抵抗を低減できる。   According to the present invention, a compressive force acts on the entire area of the core wire in the core crimping portion, and a strong compressive force acts at three locations. Therefore, more adhesion occurs and reliable conduction between the strands is ensured. And the resistance of the entire circuit can be reduced.

図１〜図５は本発明の一実施形態を示す。図１〜図３に示すように、電線Ｗは、複数の素線１ａからなる芯線１と芯線１の外周を覆う絶縁外皮２とから構成されている。電線Ｗの先端側は、絶縁外皮２が除去されて芯線１が露出されている。芯線１は、アルミニウム製又はアルミニウム合金製（以下、アルミ製）の多数の素線１ａからなり、多数の素線１ａが互いに撚られている。つまり、電線Ｗは、アルミ電線である。   1 to 5 show an embodiment of the present invention. As shown in FIGS. 1 to 3, the electric wire W includes a core wire 1 composed of a plurality of strands 1 a and an insulating sheath 2 that covers the outer periphery of the core wire 1. At the tip end side of the electric wire W, the insulating sheath 2 is removed and the core wire 1 is exposed. The core wire 1 is composed of a large number of strands 1a made of aluminum or aluminum alloy (hereinafter referred to as aluminum), and the numerous strands 1a are twisted together. That is, the electric wire W is an aluminum electric wire.

圧着端子１０は、例えば銅合金製であり、所定形状に裁断したプレートを折り曲げ加工することによって形成されている。圧着端子１０は、相手端子接続部１１と電線接続部１５を有する。電線接続部１５は、芯線圧着部１６と外皮圧着部１７を有する。芯線圧着部１６は、基底部１６ａとこの基底部１６ａの両側から延設された一対の加締め片部１６ｂを有する。芯線圧着部１６は、図２（ｂ）に詳しく示すように、芯線１の軸方向Ｃ１の間隔を置いた三箇所に他の箇所よりも強く加締めた強圧着部Ｅ１，Ｅ２，Ｅ３が設けられている。三箇所の強圧着部Ｅ１，Ｅ２，Ｅ３は、芯線１の軸方向Ｃ１に交互に対向する位置を強く加締めて設けられている。具体的には、芯線圧着部１６の先端側から後側に向かって間隔を置いて、加締め片部１６ｂの上方位置、基底部１６ａの位置、加締め片部１６ｂの上方位置で強く加締められ、これらの各位置には強い加締めによって窪み部１９ａ、１９ｂ、１９ｃがそれぞれ形成されている。   The crimp terminal 10 is made of, for example, a copper alloy, and is formed by bending a plate cut into a predetermined shape. The crimp terminal 10 has a mating terminal connection portion 11 and a wire connection portion 15. The electric wire connecting portion 15 includes a core wire crimping portion 16 and an outer skin crimping portion 17. The core wire crimping part 16 has a base part 16a and a pair of caulking piece parts 16b extending from both sides of the base part 16a. As shown in detail in FIG. 2B, the core wire crimping portion 16 is provided with strong crimping portions E1, E2, and E3 that are caulked more strongly than the other portions at three locations spaced apart in the axial direction C1 of the core wire 1. It has been. The three strong pressure-bonding portions E1, E2, and E3 are provided by caulking strongly at positions alternately facing the axial direction C1 of the core wire 1. Specifically, with a space from the front end side to the rear side of the core wire crimping portion 16, it is strongly caulked at the upper position of the caulking piece portion 16b, the position of the base portion 16a, and the upper position of the caulking piece portion 16b. In each of these positions, recesses 19a, 19b, 19c are formed by strong caulking.

芯線圧着部１６の基底部１６ａと一対の加締め片部１６ｂの内面には、多数の丸溝状のセレーション１８が形成されている。   A large number of round groove-shaped serrations 18 are formed on the inner surface of the base portion 16a of the core wire crimping portion 16 and the pair of caulking piece portions 16b.

外皮圧着部１７は、基底部１７ａとこの基底部１７ａの両側から延設された一対の加締め片部１７ｂを有する。   The outer skin crimping part 17 has a base part 17a and a pair of caulking piece parts 17b extending from both sides of the base part 17a.

圧着端子１０は、芯線圧着部１６によって露出された芯線１を加締め圧着し、外皮圧着部１７によって絶縁外皮２を加締め圧着している。   The crimp terminal 10 crimps and crimps the core wire 1 exposed by the core wire crimping portion 16, and crimps and crimps the insulating sheath 2 by the outer skin crimping portion 17.

圧着端子１０は、図４に示す加締め治具２０によって圧着される。加締め治具２０は、上下動可能なワイヤクリンパ２１と、ワイヤクリンパ２１の下方に配置されたアンビル２２を有する。ワイヤクリンパ２１の下部（加締め上側）は、最終的な加締め外周形状の加締め溝２１ａを有する。アンビル２２の上部（加締め下側）は、最終的な加締め外周形状の加締め溝２２ａを有する。ワイヤクリンパ２１の加締め溝２１ａの底面の中央には、可動クリンパ２１ｂが設けられている。可動クリンパ２１ｂは、加締め溝２１ａに進退自在に設けられている。可動クリンパ２１ｂの下端は、山形状となっている。アンビル２２の加締め溝２２ａの底面の両側部には、山形状の凸部２２ｂ、２２ｂが設けられている。   The crimp terminal 10 is crimped by a crimping jig 20 shown in FIG. The crimping jig 20 includes a wire crimper 21 that can move up and down, and an anvil 22 disposed below the wire crimper 21. The lower part (upper caulking) of the wire crimper 21 has a caulking groove 21a having a final caulking outer peripheral shape. The upper part (the lower side of the crimping) of the anvil 22 has a final crimping outer circumferential shape of the crimping groove 22a. A movable crimper 21 b is provided at the center of the bottom surface of the crimping groove 21 a of the wire crimper 21. The movable crimper 21b is provided in the caulking groove 21a so as to freely advance and retract. The lower end of the movable crimper 21b has a mountain shape. On both sides of the bottom surface of the caulking groove 22 a of the anvil 22, mountain-shaped convex portions 22 b and 22 b are provided.

図５（ａ）に示すように、アンビル２２に芯線１を載置した圧着端子１０をセットし、図５（ｂ）に示すように、可動クリンパ２１ｂを退出位置としたワイヤクリンパ２１を圧着位置に移動する。これにより、ワイヤクリンパ２１とアンビル２２によって芯線圧着部１６が加締められ、双方の加締め溝２１ａ、２２ａによって芯線圧着部１６が塑性変形される。この１回目の加締め工程で、芯線圧着部１６の２箇所に強圧着部Ｅ１，Ｅ３が形成され、強圧着部Ｅ１，Ｅ３に対応する芯線圧着部１６の下方２箇所に窪み部１９ａ，１９ｃが形成される。   As shown in FIG. 5 (a), the crimp terminal 10 with the core wire 1 placed on the anvil 22 is set, and as shown in FIG. 5 (b), the wire crimper 21 with the movable crimper 21b in the retracted position is crimped. Move to. Thereby, the core crimping part 16 is crimped by the wire crimper 21 and the anvil 22, and the core crimping part 16 is plastically deformed by both the crimping grooves 21a and 22a. In this first caulking step, strong crimping portions E1 and E3 are formed at two locations on the core wire crimping portion 16, and recesses 19a and 19c are formed at two locations below the core crimping portion 16 corresponding to the strong crimping portions E1 and E3. Is formed.

次に、ワイヤクリンパ２１を初期位置に戻し、可動クリンパ２１ｂを突出位置としたワイヤクリンパ２１を再び圧着位置に移動する。この２回目の加締め工程で、芯線圧着部１６の１箇所に強圧着部Ｅ２が形成され、強圧着部Ｅ２に対応する芯線圧着部１６の上方１箇所に窪み部１９ｂが形成される。   Next, the wire crimper 21 is returned to the initial position, and the wire crimper 21 with the movable crimper 21b as the protruding position is moved again to the crimping position. In the second caulking step, a strong crimping portion E2 is formed at one location of the core crimping portion 16, and a recess 19b is formed at one location above the core crimping portion 16 corresponding to the strong crimping portion E2.

この加締め過程では、芯線圧着部１６内の芯線１には、全域に圧縮力が作用すると共に、３箇所で強い圧縮力が作用するため、単に圧縮力を受ける場合に比較して、芯線圧着部１６の３箇所の強圧着部Ｅ１，Ｅ２，Ｅ３では、応力集中によって芯線１に大きな圧縮力が作用し、凝着が発生することにより素線１ａ間の導通を確実に確保でき、回路全体の抵抗を低減できる。   In this caulking process, the core wire 1 in the core wire crimping portion 16 has a compressive force acting on the entire area, and a strong compressive force acts at three locations. In the three strong press-bonding portions E1, E2, and E3 of the portion 16, a large compressive force acts on the core wire 1 due to stress concentration, and adhesion is generated, so that conduction between the strands 1a can be reliably ensured, and the entire circuit Resistance can be reduced.

芯線圧着部１６には、芯線１の軸方向Ｃ１に間隔を置いて３箇所に強圧着部Ｅ１，Ｅ２，Ｅ３が設けられ、且つ、３箇所の強圧着部Ｅ１，Ｅ２，Ｅ３が交互に対向する位置に強い加締め力を作用させて設けられている。従って、図２（ｂ）、（ｃ）に詳しく示すように、交互に配置された３つの窪み部１９ａ，１９ｂ，１９ｃに倣って交互に折れ曲がるため、芯線１に単に圧縮力を作用させた場合や、対向位置でなく同じ位置に強い加締め力を作用させた場合に比較して、中央の強圧着部Ｅ２では、両側の強圧着部Ｅ１，Ｅ３で芯線１の移動を拘束した状態で圧縮力が作用するため、強い圧縮力が作用する。以上より、凝着の発生が促進され、素線１ａ間の導通を更に確実に確保でき、回路全体の抵抗を更に低減できる。   The core crimping portion 16 is provided with three strong crimping portions E1, E2, E3 at intervals in the axial direction C1 of the core wire 1, and the three strong crimping portions E1, E2, E3 are alternately opposed to each other. It is provided by applying a strong caulking force to the position to be operated. Accordingly, as shown in detail in FIGS. 2B and 2C, when the core wire 1 is simply subjected to a compressive force because it bends alternately following the three recessed portions 19 a, 19 b, and 19 c arranged alternately. Compared to the case where a strong caulking force is applied to the same position, not the opposite position, the central strong pressure bonding part E2 is compressed in a state where the movement of the core wire 1 is restricted by the strong pressure bonding parts E1, E3 on both sides. Since the force acts, a strong compressive force acts. From the above, the occurrence of adhesion is promoted, conduction between the strands 1a can be more reliably ensured, and the resistance of the entire circuit can be further reduced.

芯線１は、アルミ製である。アルミ製の素線１ａは、銅合金製に較べて表面にできる酸化被膜が硬い。そのため、アルミ製の芯線１は、素線１ａ間の導通抵抗による電気抵抗の増加が問題であったが、本発明では、凝着の発生によって素線１ａ間の導通抵抗を低減できるため、特にアルミ電線に有効である。アルミ製の芯線１は、銅合金製に較べて柔らかくて伸び易いが、上記したように芯線圧着部１６の３箇所に強圧着部Ｅ１，Ｅ２，Ｅ３を設け、しかも中央の強圧着部Ｅ２と両側の強圧着部Ｅ１，Ｅ３では異なる位置を強く加締めたので、中央の強圧着部Ｅ２では、両側の強圧着部Ｅ１，Ｅ３で芯線１の移動を拘束した状態で圧縮力が作用させるため、非常に強い圧縮力を作用させることができる。本発明は、この観点からも特にアルミ電線に有効である。   The core wire 1 is made of aluminum. The aluminum wire 1a has a harder oxide film on the surface than the copper alloy. For this reason, the aluminum core wire 1 has a problem of an increase in electrical resistance due to the conduction resistance between the strands 1a. However, in the present invention, the conduction resistance between the strands 1a can be reduced by the occurrence of adhesion. Effective for aluminum wires. The aluminum core wire 1 is softer and easier to extend than the copper alloy, but as described above, the core wire crimping portion 16 is provided with the strong crimping portions E1, E2, E3, and the central strong crimping portion E2 and Since the strong crimping portions E1 and E3 on both sides are strongly crimped at different positions, a compressive force is applied to the central strong crimping portion E2 while the movement of the core wire 1 is restricted by the strong crimping portions E1 and E3 on both sides. A very strong compressive force can be applied. The present invention is particularly effective for aluminum wires from this viewpoint.

実施形態では、芯線圧着部１６に強圧着部Ｅ１，Ｅ２，Ｅ３を３箇所設けたが、芯線圧着部１６の互いに対向する２箇所に設けても良く、４箇所以上に設けても良い。   In the embodiment, the strong crimping portions E1, E2, and E3 are provided in the core wire crimping portion 16 at three locations. However, the core wire crimping portion 16 may be provided at two locations facing each other, or may be provided at four or more locations.

実施形態では、セレーション１８は、溝であるが、突部でも良く、又、溝と突部の両方であっても良い。つまり、本明細書では、セレーションとは、面上に形成される溝や凸部を意味する。   In the embodiment, the serration 18 is a groove, but may be a protrusion, or may be both a groove and a protrusion. That is, in this specification, the serration means a groove or a convex portion formed on the surface.

実施形態では、芯線１がアルミ製であるが、本発明はアルミ製以外の芯線１（例えば銅合金製）であっても適用できる。   In the embodiment, the core wire 1 is made of aluminum, but the present invention can also be applied to a core wire 1 other than aluminum (for example, made of copper alloy).
