Description
本発明は、アルミ電線用圧着端子に関する。 The present invention relates to a crimp terminal for an aluminum electric wire.
従来、アルミ電線用圧着端子としては、アルミ電線のアルミ素線からなる導体部に加締められる圧着部に対してセレーションを設けることにより、アルミ素線の表面に形成された酸化皮膜を破壊してアルミ電線と圧着端子とを接触導通させる構造が知られている(例えば、特許文献1参照)。 Conventionally, as a crimp terminal for an aluminum wire, an oxide film formed on the surface of the aluminum wire is destroyed by providing serrations on the crimped portion crimped to the conductor portion made of the aluminum wire of the aluminum wire. A structure in which an aluminum electric wire and a crimp terminal are brought into contact with each other is known (see, for example, Patent Document 1).
また、端子の圧着部に形成されたセレーションについては、セレーションを構成する溝の深さとアルミ電線のアルミ素線の径との比を0.33以上、溝数を3以上にするなどの検討も行われている(例えば、特許文献2参照)。
In addition, with regard to serrations formed in the crimping part of the terminal, studies have been made such as making the ratio of the depth of the grooves constituting the serration and the diameter of the aluminum wire of the aluminum wire 0.33 or more and the number of
さらに、端子などの基材上に形成されるめっき層としては、ニッケルなどからなる下地層と、銅などからなる中間層と、銀などからなる最表層とを有する被覆層中に含まれる銅の総量を被覆面積1m2あたり0.025mol以下とした可動接点用銀被膜複合材料が知られている(例えば、特許文献3参照)。
アルミ電線に圧着される圧着端子は、アルミ電線との接触面に錫(Sn)などのアルミ電線のアルミニウム(Al)と凝着作用を有するめっき層が形成されている。そして、導体部の表面に形成された酸化皮膜を破壊することにより、導体部の新生面(素地)を露出させ、Sn−Alとの金属間結合(凝着)によってアルミ電線と端子とを導通接触させている。 The crimp terminal to be crimped to the aluminum electric wire has a plating layer having an adhesion action with aluminum (Al) of the aluminum electric wire such as tin (Sn) on the contact surface with the aluminum electric wire. Then, by destroying the oxide film formed on the surface of the conductor part, the new surface (substrate) of the conductor part is exposed, and the aluminum electric wire and the terminal are brought into conductive contact by intermetallic bonding (adhesion) with Sn-Al. I am letting.
そこで、Sn−Alの結合面としての凝着面積を稼ぐため、上記の特許文献1,2に記載された技術のように端子におけるアルミ電線との接触面にセレーションを設けた圧着端子がある。すなわち、このような圧着端子は、圧着部でアルミ電線の導体部を圧着する際に、導体部の表面に形成された酸化皮膜をセレーションによって破壊させて導体部の新生面の面積を増加させてSn−Alの凝着面積を稼いでいる。 Therefore, there is a crimp terminal in which serrations are provided on the contact surface of the terminal with the aluminum electric wire as in the techniques described in Patent Documents 1 and 2 in order to increase the adhesion area as the Sn—Al bonding surface. That is, when such a crimp terminal crimps the conductor portion of the aluminum electric wire at the crimp portion, the oxide film formed on the surface of the conductor portion is destroyed by serration to increase the area of the new surface of the conductor portion. -Earn Al adhesion area.
しかしながら、端子の圧着部の接触面に形成されためっき層の表面にも酸化皮膜が形成されている。そこで、めっき層表面の酸化皮膜を破壊させてめっき層の新生面を露出させる必要があるが、錫などからなるめっき層は比較的硬度が低い。このため、めっき層表面の酸化皮膜は、圧着部でアルミ電線の導体部を圧着する際にめっき層の変形に追従して伸びてしまい、圧着部による導体部の圧縮率が高い領域ではめっき層表面の酸化皮膜が破壊されない可能性があった。 However, an oxide film is also formed on the surface of the plating layer formed on the contact surface of the crimping portion of the terminal. Therefore, it is necessary to break the oxide film on the surface of the plating layer to expose the new surface of the plating layer, but the plating layer made of tin or the like has a relatively low hardness. For this reason, the oxide film on the surface of the plating layer expands following the deformation of the plating layer when the conductor portion of the aluminum electric wire is crimped by the crimping portion, and in the region where the compressibility of the conductor portion by the crimping portion is high, the plating layer There was a possibility that the oxide film on the surface was not destroyed.
なお、導体部の圧縮率とは、圧着部による圧着後の導体部の断面積に対する圧着前の導体部の断面積の比の値とする。従って、例えば、強い圧着力で導体部を圧着した場合には圧縮率が低くなり、弱い圧着力で導体部を圧着した場合には圧縮率が高くなる。 The compression ratio of the conductor portion is a value of the ratio of the cross-sectional area of the conductor portion before crimping to the sectional area of the conductor portion after crimping by the crimping portion. Therefore, for example, when the conductor part is crimped with a strong crimping force, the compression ratio is low, and when the conductor part is crimped with a weak crimping force, the compression ratio is high.
また、圧着部による導体部の圧縮率を低くすると、めっき層の変形量が増加してめっき層表面に形成された酸化皮膜が破壊され、めっき層の新生面露出面積が大きくなり、凝着面積を稼ぐことができる。 Also, if the compression ratio of the conductor part by the crimping part is lowered, the deformation amount of the plating layer increases, the oxide film formed on the surface of the plating layer is destroyed, the exposed area of the new surface of the plating layer increases, and the adhesion area is reduced. You can earn.
しかしながら、導体部の圧縮率を低くしてしまうと、アルミ電線では銅素線からなる銅電線に比べて機械的強度が劣るため、セレーションによるアルミ素線の破断やセレーションが形成されていない圧着部でも圧着部自体によるアルミ素線の破断が起こる可能性があった。 However, if the compressibility of the conductor part is lowered, the mechanical strength of the aluminum wire is inferior to that of the copper wire made of copper wire, so the crimped portion where the aluminum wire is not broken or serrated by serration. However, there was a possibility that the aluminum wire was broken by the crimping part itself.
また、導体部の圧縮率を低くしてしまうと、圧着部の加締めによって発生する圧着部自体の反発(スプリングバック)も大きくなり、圧着部とアルミ素線との間のすき間が大きくなり、導体部と圧着部との圧着強度が低下してしまう可能性があった。 Moreover, if the compression ratio of the conductor part is lowered, the repulsion (spring back) of the crimping part itself caused by crimping of the crimping part also increases, and the gap between the crimping part and the aluminum element wire becomes large, There was a possibility that the crimping strength between the conductor part and the crimping part would decrease.
そこで、この発明は、凝着面積を稼ぐための過度な加工をする必要がなく、高い圧縮率の領域でも安定した接続信頼性を得ることができるアルミ電線用圧着端子の提供を目的としている。 Accordingly, an object of the present invention is to provide a crimp terminal for an aluminum electric wire that does not require excessive processing for increasing the adhesion area and can obtain stable connection reliability even in a high compression rate region.
請求項1記載のアルミ電線用圧着端子は、アルミニウム系金属の複数の素線からなる導体部を有するアルミ電線の前記導体部に圧着され、銅系金属からなる圧着部と、この圧着部の前記導体部と接触する接触面に設けられ、前記導体部に対して凝着作用を有するめっき層と、このめっき層の表面に設けられ、前記めっき層よりも硬度が高い高硬度めっき層とを有することを特徴とする。 The crimp terminal for an aluminum wire according to claim 1 is crimped to the conductor portion of an aluminum electric wire having a conductor portion made of a plurality of aluminum-based metal wires, and the crimp portion made of a copper-based metal, and the crimp portion of the crimp portion. A plating layer provided on a contact surface in contact with the conductor portion and having an adhesion action on the conductor portion; and a high-hardness plating layer provided on a surface of the plating layer and having a hardness higher than that of the plating layer. It is characterized by that.
請求項2記載のアルミ電線用圧着端子は、前記めっき層は、錫系金属からなることを特徴とする。 The crimp terminal for an aluminum electric wire according to claim 2, wherein the plating layer is made of a tin-based metal.
請求項3記載のアルミ電線用圧着端子は、前記高硬度めっき層は、前記めっき層の厚さよりも薄いことを特徴とする。
The crimp terminal for an aluminum electric wire according to
請求項1のアルミ電線用圧着端子は、めっき層よりも硬度が高い高硬度めっき層がめっき層の表面に設けられているので、圧着部でアルミ電線の導体部を圧着する際に高硬度めっき層が破壊され易くなっている。そして、高硬度めっき層の表面に形成された酸化皮膜が高硬度めっき層の破壊と共に破壊され、めっき層の新生面が露出される。 The crimp terminal for an aluminum electric wire according to claim 1 is provided with a high-hardness plating layer having a higher hardness than the plating layer on the surface of the plating layer. The layer is easily destroyed. The oxide film formed on the surface of the high-hardness plating layer is destroyed along with the destruction of the high-hardness plating layer, and the new surface of the plating layer is exposed.
これにより、めっき層表面に形成される酸化皮膜を破壊させて凝着面積を稼ぐため、圧着部による導体部の圧縮率を過度に低くさせる必要がない。 Thereby, since the oxide film formed on the plating layer surface is destroyed to increase the adhesion area, it is not necessary to excessively reduce the compressibility of the conductor portion by the crimping portion.
従って、このようなアルミ電線用圧着端子では、凝着面積を稼ぐための過度な加工をする必要がなく、高い圧縮率の領域でも安定した接続信頼性を得ることができる。 Therefore, in such a crimp terminal for an aluminum electric wire, it is not necessary to perform excessive processing for increasing the adhesion area, and stable connection reliability can be obtained even in a high compression ratio region.
請求項2のアルミ電線用圧着端子は、めっき層が比較的硬度の低い錫系金属であっても、高い圧縮率の領域で確実に酸化皮膜を破壊させることができる。 The crimp terminal for an aluminum electric wire according to claim 2 can reliably break the oxide film in a high compressibility region even if the plating layer is a tin-based metal having a relatively low hardness.
請求項3のアルミ電線用圧着端子は、高硬度めっき層がめっき層の厚さよりも薄いので、破壊された後でも高硬度めっき層がアルミ電線と端子との接触抵抗になる影響を抑制することができる。

図1〜図6に示すように、アルミ電線7は、アルミニウム又はアルミニウム合金などのアルミニウム系金属からなる複数の素線3が撚られた導体部5と、この導体部5を被覆する絶縁被覆15とを備えている。このアルミ電線7は、絶縁被覆15が所定長さ剥がされ、露出した導体部5に対してアルミ電線用圧着端子1が圧着される。
As shown in FIGS. 1 to 6, the aluminum electric wire 7 includes a conductor portion 5 in which a plurality of
アルミ電線用圧着端子1は、銅又は銅合金などの銅系金属からなり、電気接続部17と、圧着部9とを備えている。電気接続部17は、ボルト(不図示)などの固定手段が貫通可能な孔19が形成され、固定手段によって固定されることにより、相手側の接続部材(不図示)と導通される。圧着部9は、電気接続部17と底板21を介して連続する一部材で形成され、一対の圧着片23,23と、一対の加締め片25,25とを備えている。
The crimp terminal 1 for an aluminum wire is made of a copper-based metal such as copper or a copper alloy, and includes an
一対の圧着片23,23は、電気接続部17側で底板21の両側部に底板21と一体に立設されている。この一対の圧着片23,23は、アルミ電線7の導体部5の外周側を包囲するように加締められ、アルミ電線7とアルミ電線用圧着端子1とを導通接触させる。一対の加締め片25,25は、アルミ電線7側で底板21の両側部に底板21と一体に立設されている。この一対の加締め片25,25は、アルミ電線7の絶縁被覆15の外周側を包囲するように加締められ、アルミ電線7とアルミ電線用圧着端子1とを固定する。
The pair of
このような圧着部9でアルミ電線7を加締める(圧着する)ことにより、アルミ電線7が伸びて導体部5の表面に形成された酸化皮膜が破壊され、新生面が露出される。この新生面が導体部5と圧着部9との凝着面となる。この凝着面となる圧着部9の導体部5との接触面にはめっき層11が形成されている。

めっき層11は、錫又は錫合金などの錫系金属からなり、底板21の内面及び一対の圧着片23,23の内面にめっきされている。また、本実施の形態においては、めっき層11の厚さは、例えば1.0μmで形成されることが好ましい。このめっき層11は比較的硬度が低く、表面に酸化皮膜が形成された場合、圧着部9の圧着によるめっき層11の変形に追従して酸化皮膜が伸びてしまい、酸化皮膜の破壊が不十分となり、めっき層11の新生面露出面積が不十分となる可能性がある。このため、酸化皮膜の破壊を促進するためにめっき層11の表面には、高硬度めっき層13が設けられている。
The
高硬度めっき層13は、錫系金属からなるめっき層11よりも硬度が高いタングステン(W)、アルミニウム(Al)、ニッケル(Ni)、亜鉛(Zn)、クロム(Cr)、モリブデン(Mo)、コバルト(Co)などを蒸着、スパッタリングなどにより、めっき層11の表面に設けられている。また、本実施の形態においては、高硬度めっき層13の厚さは、例えば数十nm程度に形成されることが好ましい。この高硬度めっき層13は、圧着部9の圧着によるめっき層11の変形に追従することがなく、圧着部9の変形によって破壊される。従って、高硬度めっき層13の表面に形成された酸化皮膜は、高硬度めっき層13の破壊と共に破壊され、めっき層11の新生面27を露出することができる。なお、高硬度めっき層13は、厚さが非常に薄く、破壊後の接触抵抗への影響が抑制されているため、導電性の金属に限らず、例えばシリコン、DLC(ダイヤモンドライクカーボン)などの絶縁体であってもよい。
The high-
このようなアルミ電線用圧着端子1では、めっき層11よりも硬度が高い高硬度めっき層13がめっき層11の表面に設けられているので、圧着部9でアルミ電線7の導体部5を圧着する際に高硬度めっき層13が破壊され易くなっている。そして、高硬度めっき層13の表面に形成された酸化皮膜が高硬度めっき層13の破壊と共に破壊され、めっき層11の新生面27が露出される。

従って、このようなアルミ電線用圧着端子1では、凝着面積を稼ぐための過度な加工をする必要がなく、高い圧縮率の領域でも安定した接続信頼性を得ることができる。 Therefore, in such a crimp terminal 1 for an aluminum electric wire, it is not necessary to perform excessive processing for increasing the adhesion area, and stable connection reliability can be obtained even in a high compression ratio region.
