- the electric wire conductor 10 has a two-layer structure in which the copper-coated layer 12 is provided on the outer periphery of the core wire 11 made of SUS (hereinafter, sometimes referred to as a copper-coated SUS wire).
- SUS forming the core wire 11 is a highly rigid metal having a high Young's modulus.
- copper or a copper alloy, especially pure copper, which constitutes the copper coating layer 12 is a low-rigidity metal having a Young's modulus lower than that of SUS.
- the SUS core wire 11 and the copper covering layer 12 are combined, so that the overall Young's modulus is suppressed to less than 1.1 ⁇ 10 5 MPa.
- the Young's modulus of Cu—Sn alloy wire which is a copper alloy having relatively high strength, is 1.1.
- the Young's modulus of the copper-clad SUS wire 10 according to this embodiment is about ⁇ 10 5 MPa, which is lower than that of the Cu—Sn alloy wire.
- the Young's modulus of the copper-clad SUS wire 10 is further reduced to less than 1.0 ⁇ 10 5 MPa, further less than 9.0 ⁇ 10 4 MPa, and 8.0 ⁇ 10 4 through softening of the copper covering layer by heat treatment.

- the Young's modulus of a metal wire is evaluated by a tensile test conforming to JIS Z 2241.
- the copper-clad SUS wire 10 has a Young's modulus lower than that of the Cu--Sn alloy wire, so that the buckling force is smaller than that of the Cu--Sn alloy wire.
- the buckling force is the magnitude of the force required to cause the wire to buckle, and the larger the value, the greater the force required to cause the wire to buckle. .
- the higher the Young's modulus of the material forming the outer periphery of the wire the greater the buckling force of the wire. This is because the material of the outer peripheral portion of the wire contributes to the buckling force P with a large two-dimensional moment of area I.
- P buckling force (N)
- E Young's modulus
- I two-dimensional moment of area
- L sample length (mm).
- the buckling force P tends to be small. That is, the buckling force of the copper-clad SUS wire 10 according to the present embodiment tends to be smaller than that of the conventional general Cu—Sn alloy wire. This means that the copper-clad SUS wire 10 is more likely to buckle even when it is inserted into the connector terminal with a small force. Actually, it has been confirmed in later examples that the copper-clad SUS wire 10 exhibits a smaller buckling force than the Cu--Sn alloy wire. Thus, it can be said that the copper-clad SUS wire 10 is more susceptible to buckling than the Cu—Sn alloy wire in terms of the magnitude of the buckling force.
- the copper-clad SUS wire 10 does not deform due to buckling due to the structural effect of having a low-rigidity, that is, a highly flexible copper-clad layer 12 on the outer periphery of the high-rigidity SUS core wire 11. Even if it is added, the deformation is easily eliminated. This is because the SUS core wire 11 with a high Young's modulus exhibits a large restoring force, and the copper coating layer 12 with a low Young's modulus can flexibly eliminate deformation due to the restoring force.
- one end of the wire rod 10′ is fixed to form a fixed end 10a, and the other end is assumed to be a moving end 10b.
- the wire rod 10' is buckled at .
- the amount of deformation of the wire rod 10′ in the vertical direction due to buckling that is, the buckling amount ⁇ y is suppressed to be smaller when the wire rod 10′ is the copper-clad SUS wire 10 than when it is the Cu—Sn alloy wire.
- the buckling amount ⁇ y is defined as the distance between the straight line connecting both ends 10a and 10b of the wire rod 10' and the top of the buckling portion 10c.
- the angle ⁇ of the buckling portion 10c is kept larger than when it is a Cu—Sn alloy wire, and the buckling portion 10c is less likely to bend steeply.
- the deformation is reversible when the application of the force F is stopped. easy to dissolve.
- the copper-clad SUS wire 10 is less prone to buckling than the Cu—Sn alloy wire.
- the buckling amount ⁇ y is large, and the buckling portion 10c tends to form a sharp bent shape (see FIG. 5C ), in the copper-clad SUS wire 10, the amount of buckling ⁇ y is kept small, and the buckling portion 10c does not bend sharply, but tends to take a gentle curved shape (see FIG. 5A).
- the copper-clad SUS wire 10 is more susceptible to buckling than the Cu—Sn alloy wire in that it has a smaller buckling force, but when buckling occurs, the amount of buckling is kept small. In terms of the fact that it can be In other words, the copper-clad SUS wire 10 is likely to buckle even with a small force while being inserted into a connector terminal, but the amount of buckling when buckling occurs can be kept small. In addition, it is difficult to irreversibly retain the deformation due to buckling.
- the buckling force is large and the wire conductor does not buckle unless a large force is applied. Moreover, if the buckled state is irreversibly maintained, the effect of buckling will increase. For example, a situation may arise in which the electric wire conductor cannot be fully inserted into the connector terminal due to the buckling, or the electric wire conductor inserted in the connector terminal continues to be in a buckled state.
- the amount of buckling that occurs at that time is If is small, the insertion of the wire conductor 10 into the connector terminal can be completed in a nearly normal state even with buckling.
- the buckling can be prevented by removing the wire conductor 10 from the connector terminal once and stopping the application of force. is reversibly resolved.
- the wire conductor 10 can be normally inserted into the connector terminal.
- the electric wire conductor 10 made of the copper-clad SUS wire according to the present embodiment as an effect of the structure in which the low-rigidity copper covering layer 12 is arranged on the outer periphery of the high-rigidity SUS core wire 11, buckling occurs. Since the amount is kept small and buckling is easily eliminated, the effect of buckling can be kept small.
- the SUS core wire 11 and the copper-coated layer 12 may have any physical properties. Since SUS has a higher Young's modulus than copper and copper alloys, the SUS core wire 11 alone exhibits a higher Young's modulus than the copper-clad SUS wire 10, but the Young's modulus of the SUS core wire 11 is It preferably exceeds 1.1 ⁇ 10 5 MPa, which is the value of a Cu—Sn alloy wire. Furthermore, the Young's modulus of the SUS core wire 11 is preferably 1.2 ⁇ 10 5 MPa or more, and 1.5 ⁇ 10 5 MPa or more. The higher the Young's modulus of the SUS core wire 11, the higher the buckling force of the copper-clad SUS wire 10 as a whole, and the higher the restoring force. and the amount of buckling can be reduced.
- the copper-clad SUS wire 10 has a core wire 11 made of SUS, it has a higher tensile strength than conventional general Cu--Sn alloy wires. Although the tensile strength of the copper-clad SUS wire 10 can be adjusted by the heat treatment conditions, the tensile strength does not significantly affect the amount of buckling, as shown in Examples below. However, if the copper-clad SUS wire 10 has a high tensile strength, a high crimping strength can be obtained at the crimping portion when the copper-clad SUS wire 10 inserted into the connector terminal is crimped and connected. That is, the copper-clad SUS wire 10 compressed at the crimping portion is less likely to break.
- the copper-clad SUS wire 10 is inserted into the connector terminal while suppressing the buckling effect, and then the high tensile strength of the copper-clad SUS wire 10 is applied. It can be used to form a crimp with high connection strength through a crimp connection. From the viewpoint of effectively increasing the crimping strength at the crimping portion, the tensile strength of the copper-clad SUS wire 10 is preferably 950 MPa or more, more preferably 970 MPa or more. The tensile strength of the metal wire can be evaluated as the tensile strength at break by a tensile test conforming to JIS Z 2241.
- the upper limit of the tensile strength of the copper-clad SUS wire 10 is not particularly defined, but even if the tensile strength is too high, the connection strength at the connecting portion with the connector terminal may rather decrease. If the copper-clad SUS wire 10 has high strength and becomes too hard, the strength of the material on the connector terminal side may be reduced when the connector terminal is crimped, and the copper-clad SUS wire 10 may be sufficiently deformed. This is because the copper-clad SUS wire 10 cannot be firmly held by the connector terminal, and the connection strength may be lowered.
- the tensile strength of the copper-clad SUS wire 10 is preferable to keep the tensile strength of the copper-clad SUS wire 10 at 1200 MPa or less, further 1080 MPa or less.

- each wire conductor prepared above was as shown in Table 2 below.
- the table also shows the physical properties of the SUS core wire alone ( ⁇ 0.16 mm, no softening) used as the raw material for the copper-clad SUS wire.
- An insulating coating was formed on the outer periphery of the softened and unsoftened copper-clad SUS wires and the Cu-Sn alloy wires prepared above to produce insulated wires.
- the insulation coating was formed with a thickness of 0.20 mm by extrusion molding of PVC.
- the buckling force was measured for the insulated wires having the respective wire conductors produced above. Each insulated wire was cut to 30 mm and subjected to a buckling test. In the buckling test, as shown in FIG. 3A, one end of the insulated wire was a fixed end 10a and the other end was a moving end 10b. At this time, the moving distance of the moving end 10b was taken as the test distance, and the relationship with the applied force F was recorded. The maximum value of the applied force F becomes the buckling force. The moving speed of the moving end 10b was set to 25 mm/min. In the tester used, a jig for holding both ends of the insulated wire of the sample is provided with holes each having a depth of 10 mm for fixing the sample.
- FIG. 4 shows the relationship between the test distance and the force applied to the insulated wire obtained in the buckling test.
- the buckling force read as the maximum applied force, was given in Table 3 below.
- the copper-clad SUS wire exhibits a smaller buckling force than the Cu—Sn alloy wire both when softened and when not softened. That is, the copper clad SUS wire causes buckling even with a smaller force than the Cu—Sn alloy wire. In particular, the softened copper clad SUS wire exhibits a small buckling force.
- the copper-clad SUS wire has a copper coating layer made of a material with a low Young's modulus on the surface, and accordingly, in comparison with the Cu-Sn alloy wire, the difference in Young's modulus as a whole is can be interpreted as having a large difference as a difference in buckling force.
- the heat treatment further reduces the Young's modulus of the copper-clad SUS wire, particularly the Young's modulus of the outer peripheral portion. It is considered that the buckling force is even smaller than the buckling force of
- ⁇ Evaluation method> A buckling test was performed in the same manner as in test [1] above. At this time, the buckling test was stopped when a predetermined test distance set at intervals of 0.5 mm between 0.5 mm and 2.5 mm was reached. Then, the insulated wire was removed from the tester, and the amount of buckling ⁇ y, that is, the amount of change in the dimension in the vertical direction was measured. For each test distance, three measurements were taken with different samples, and the average amount of buckling was recorded.
- FIGS. 5A to 5C respectively show the states of the insulated wire having the copper-clad SUS wire after softening, the copper-clad SUS wire without softening, and the Cu—Sn alloy wire when buckling at a test distance of 2.0 mm.
- the central buckling portion is sharply bent and the angle ⁇ of the buckling portion is small.
- the amount of buckling is also large.
- the copper-clad SUS wire after softening shown in FIG. 5A the insulated wire has a gentle mountain-like shape, and the angle ⁇ of the buckling portion is large.
- the amount of buckling is also clearly smaller than in the case of FIG. 5C.
- the copper-clad SUS wire without softening in FIG. 5B it takes an intermediate state between FIGS. 5A and 5C.
- the buckling amount in the area up to the test distance of 2.0 mm was slightly higher in the state after softening. It's getting smaller. This result is interpreted to mean that the heat treatment improves the flexibility of the copper coating layer, further enhancing the effect of eliminating deformation due to buckling.
- the hardness of the copper coating layer was measured in the cross section of the copper-clad SUS wire, it was 152 Hv in the state without softening and 93 Hv in the state after softening.
- ⁇ Evaluation method> The tensile strength at break of each copper-clad SUS wire produced above was evaluated by a tensile test according to JIS Z 2241.
- the insulated wires having each copper-clad SUS wire were subjected to a buckling test in the same manner as in test [2] above, and the amount of buckling ⁇ y at a test distance of 5.0 mm was measured.
- the length of the insulated wire used for the test was 30 mm. Again, the same measurement was performed three times with different samples, and the average value of the amount of buckling was recorded.
- FIG. 7 is a bar graph showing the relationship between the tensile strength and the amount of buckling of the copper-clad SUS wire. According to FIG. 7, the amount of buckling does not show a systematic change as the tensile strength changes, and shows a similar amount of buckling across the tensile strength. This result indicates that the tensile strength of the copper clad SUS wire does not significantly affect the amount of buckling.
- the buckling of the wire conductor and the elimination of the buckling deformation are due to the behavior of the elastic region of the wire conductor, and it is considered that the tensile strength corresponding to the behavior at the time of breakage is almost unrelated to the plastic region. .
- the buckling strength is a quantity that depends on Young's modulus, which is a physical property in the elastic region. This agrees with the evaluation results in FIG.
- the tensile strength of SUS wire can vary greatly depending on the heat treatment conditions, but the Young's modulus is not so affected by the heat treatment conditions.
- ⁇ Evaluation method> Tensile strength at break was evaluated by a tensile test based on JIS Z 2241 for each of the produced electric wire conductors. Also, the prepared electric wire conductor was cut into a length of 104 mm, and crimped and connected with a crimp terminal to obtain a conductor with a terminal. A crimp terminal made of a copper alloy was used, and when crimping and connecting, the wire conductor was sandwiched and compressed from the opposite direction in a region extending from 1.6 to 3.0 mm in length along the axial direction of the wire conductor. . As the crimping portion, two types of crimping portions, low compression and high compression, were formed by changing the degree of compression with respect to the conductor. The low-compression state is employed in a normal connection between a connector terminal and a wire conductor, and the high-compression state corresponds to a state in which the wire conductor is compressed under more severe conditions than usual.
- a crimp terminal was fixed to the obtained conductor with a terminal, and the end of the wire conductor was pulled. Then, the maximum value of the force applied until the wire conductor broke at the crimped portion was recorded as the crimping strength.
- the tensile speed was set to 100 mm/min. In all samples, the breakage of the crimped portion was caused by the breakage of the wire conductor itself inside the crimp terminal, not by the separation of the conductor from the crimp terminal.
- FIG. 8A and 8B show the relationship between the tensile strength of the copper-clad SUS wire and the crimping strength.
- FIG. 8A shows the case of low compression
- FIG. 8B shows the case of high compression.
- the solid line indicates the level at which the crimping strength is 30N.
- crimping strength of 30 N or more is obtained over the entire tensile strength of 950 MPa or more.
- a crimping strength of 30 N or more is obtained in the region where the tensile strength of the wire conductor is 950 MPa or more and 1080 MPa or less. In a region where the tensile strength is higher than 1080 MPa, the crimping strength is lowered. This is probably because the material strength of the crimp terminal was reduced due to the hardness of the wire conductor, and the wire conductor could not be firmly held by the crimp terminal.
- the crimping strength of the copper alloy conductor of the reference sample was 23.6 N in the case of low compression and 25.4 N in the case of high compression.
- the tensile strength of the copper-clad SUS wire does not affect the amount of buckling, but from the results of FIGS. know to have an impact.
- the tensile strength must be appropriately set in order to secure a high crimping strength after crimping the connection. It will be fine.
- the low-compression state is employed in normal connector terminal connections, and in order to ensure a high crimping strength of 30 N or more in such normal terminal connections, a compression strength of 950 MPa or more is required.
- the heat treatment conditions for the copper-clad SUS wire should be selected so that the tensile strength of is obtained, and when terminal connection is assumed under conditions of higher compression than usual, the tensile strength should not be increased too much. It can be said that it is preferable to The elongation at break of the copper-clad SUS wire tested here was in the range of 1.9% to 2.2%.

Abstract
Description
最初に本開示の実施形態を列記して説明する。
本開示にかかる電線導体は、ステンレス鋼より構成される単線の芯線と、銅または銅合金より構成され、前記芯線の外周を被覆する銅被覆層と、を有し、導体断面積が0.13mm2未満であり、ヤング率が1.1×105MPa未満であり、単線の状態で使用される。
以下に、本開示の実施形態について、図面を用いて詳細に説明する。本明細書において、「平行」「垂直」等、部材の形状や配置を示す語には、幾何的に厳密な概念のみならず、通信用電線として一般に許容される範囲の誤差も含むものとする。また、本明細書において、各種物性は、大気中、室温(おおむね15~25℃)にて計測される値とする。
図1に、本開示の一実施形態にかかる電線導体10を含んだ、本開示の一実施形態にかかる絶縁電線1の断面を表示する。
次に、電線導体10が有する特性について、詳細に説明する。
P=(π2×E×I)/(4×L2) (1)
ここで、Pは座屈力(N)、Eはヤング率(MPa)、Iは断面二次元モーメント(mm4)、Lはサンプル長さ(mm)である。
銅覆SUS線として構成される本実施形態にかかる電線導体10を製造する方法としては、例えば、伸線によって所定の径を有するSUSの芯線11を製造したうえで、めっきや蒸着により、銅被覆層12をその芯線11の表面に形成すればよい。あるいは、芯線11となるSUS材の周囲に、銅被覆層12となる環状の銅材を嵌め込み、所定の径まで一体に伸線することでも、銅覆SUS線10を製造することができる。
上記実施形態にかかる銅覆SUS線として構成された電線導体10は、どのような形態で使用されてもよく、図1に示したような1本の電線導体10の全周を絶縁被覆20で被覆した単純な絶縁電線1を構成する形態に限られない。上記実施形態にかかる電線導体10を用いて、他の形態の絶縁電線を構成する場合の例として、フラット電線について、簡単に説明する。
まず、電線導体の材質と座屈力の関係について検証した。
試料として、3種の電線導体を準備した。まず、SUS 304H材よりなる芯線と、純銅よりなる銅被覆層とを有する銅覆SUS線を作製した。芯線の外径は、φ0.16mmとし、銅被覆層の厚さは45μmとした。銅覆SUS線全体としては、外径がφ0.25mm、導体断面積にして0.05mm2となった。得られた銅覆SUS線を、そのまま「軟化なし」の試料とした。一方、得られた銅覆SUS線に対して連続軟化を施し、「軟化後」の試料とした。別途、φ0.25mmのCu-Sn合金線(Sn含有量:0.3質量%)を準備した。
上記で作製した各電線導体を有する絶縁電線に対して、座屈力を測定した。各絶縁電線を30mmに切り出し、座屈試験を行った。座屈試験においては、図3Aに示すように、絶縁電線の一端を固定端10a、他端を移動端10bとし、移動端10bに、固定端10aに向かって押し込む力Fを印加した。この際、移動端10bの移動距離を試験距離とし、印加した力Fとの関係を記録した。印加した力Fの最大値が座屈力となる。移動端10bの移動速度は、25mm/minとした。なお、用いた試験機においては、試料の絶縁電線の両端を保持する治具に、試料を固定するための深さ10mmの穴がそれぞれ設けられている。
図4に、座屈試験で得られた、試験距離と絶縁電線に印加した力との関係を示す。印加した力の最大値として読み取られる座屈力は、下の表3のようになった。
次に、電線導体の材質と座屈量の関係について検証した。
上記試験[1]で用いたのと同じ、軟化後の銅覆SUS線、軟化なしの銅覆SUS線、Cu-Sn合金線の3種の導体を有する絶縁電線を試料として用いた。
上記試験[1]と同様に座屈試験を行った。この際、0.5mmから2.5mmまでの間で、0.5mmおきに設定した所定の試験距離に達した段階で、座屈試験を中止した。そして、絶縁電線を試験機から取り外し、座屈量Δy、つまり縦方向の寸法の変化量を計測した。各試験距離について、試料を交換して測定を3回行い、座屈量の平均値を記録した。
図5A~5Cにそれぞれ、試験距離2.0mmで座屈させた場合について、軟化後の銅覆SUS線、軟化なしの銅覆SUS線、Cu-Sn合金線を有する絶縁電線の状態を示す。図5CのCu-Sn合金線の場合には、中央の座屈部が鋭く折れ曲がっており、座屈部の角度θが小さくなっている。座屈量も大きくなっている。一方、図5Aの軟化後の銅覆SUS線の場合には、絶縁電線が緩やかな山なりの形状をとっており、座屈部の角度θが大きくなっている。座屈量も明らかに図5Cの場合よりも小さくなっている。図5Bの軟化なしの銅覆SUS線の場合は、図5Aと図5Cの中間的な状態をとっている。
次に、銅覆SUS線の引張強さと座屈量の関係について検証した。
上記試験[1]で作製した熱処理後の銅覆SUS線を有する絶縁電線と同様の試料を準備した。ただし、ここでは、軟化のための熱処理条件を異ならせることにより、引張強さの異なる複数の銅覆SUS線を作製した。なお、いずれの条件の熱処理を経た場合にも、電線導体の電気抵抗は、660mΩ/m以下であった。
上記で作製した各銅覆SUS線の破断時の引張強さを、JIS Z 2241に準拠した引張試験によって評価した。また、各銅覆SUS線を有する絶縁電線について、上記試験[2]と同様に、座屈試験を行い、試験距離5.0mmにおける座屈量Δyを計測した。試験に用いる絶縁電線の長さは30mmとした。ここでも、試料を交換して同じ測定を3回行い、座屈量の平均値を記録した。
図7に、銅覆SUS線の引張強さと座屈量の関係を、棒グラフにて表示する。図7によると、引張強さが変化しても、座屈量は系統的な変化を示しておらず、引張強さの全域で、類似した座屈量を示している。この結果は、銅覆SUS線の引張強さは、座屈量に大きな影響を与えないということを示している。
次に、銅覆SUS線の引張強さと、端子接続部における圧着強度との関係について検証した。
上記試験[3]と同様に、軟化のための熱処理条件を異ならせることにより、引張強さの異なる複数の銅覆SUS線を作製した。合わせて、参照試料として、導体断面積0.05mm2の銅合金導体(引張強さ:740MPa、破断伸び:2.1%)も準備した。
作製した各電線導体に対して、JIS Z 2241に準拠した引張試験により、破断時の引張強さを評価した。また、作製した電線導体を、長さ104mmに切り出し、圧着端子にて圧着接続して、端子付き導体を得た。圧着端子としては、銅合金製のものを用い、圧着接続に際しては、電線導体の軸線方向に沿って長さ1.6~3.0mmにわたる領域において、電線導体を対向する方向から挟み込んで圧縮した。圧着部としては、導体に対する圧縮度を変化させることで、低圧縮と高圧縮の2とおりの圧着部を形成した。低圧縮の状態は、通常のコネクタ端子と電線導体の間の接続部において採用されるものであり、高圧縮の状態は、通常よりも厳しい条件で電線導体を圧縮している状態に相当する。
図8A,8Bに、銅覆SUS線の引張強さと、圧着強度との関係を示す。図8Aが低圧縮の場合、図8Bが高圧縮の場合を示している。各図では、圧着強度が30Nの水準を、実線で表示している。
