本考案は高圧送電線等のアルミニウム又はアルミニウム合金からなる電線を受 変電設備等に接続する継手として好適の接続端子に関する。 This invention is designed to receive electric wires made of aluminum or aluminum alloy such as high-voltage power transmission lines. The present invention relates to a connection terminal suitable as a joint for connecting to substation equipment, etc.
【０００２】0002
従来、高層ビル等において使用する電力用高圧送電線には、電線重量を軽減す るためにアルミニウム又はアルミニウム合金が使用されている。一方、このよう な高圧送電線から供給される電力を受電し、変圧する変圧器においては、ブスバ ー等の導体部分に銅が使用されている。このため、アルミニウム又はアルミニウ ム合金からなる電線と変圧器の銅製の導体部分とをそのまま接続すると、相互間 のエネルギー準位の差により接続部分に電気的腐食（以下、電食という）が発生 する。 Conventionally, high-voltage power transmission lines used in high-rise buildings, etc. have been designed to reduce the weight of the wires. Aluminum or aluminum alloys are used for this purpose. On the other hand, like this Busbars are used in transformers that receive and transform power supplied from high-voltage power transmission lines. Copper is used in conductor parts such as -. For this reason, aluminum or If you connect the copper alloy wire and the copper conductor of the transformer as is, there will be no connection between them. Electrical corrosion (hereinafter referred to as electrolytic corrosion) occurs at the connection part due to the difference in energy level between do.
【０００３】 そこで、予め端子本体の接続面に銅板又は銅メッキ層を設けることにより、電 食を防止した接続端子が種々提案されている。0003 Therefore, by providing a copper plate or copper plating layer on the connection surface of the terminal body in advance, it is possible to Various corrosion-resistant connection terminals have been proposed.
【０００４】 図７は従来の圧縮接続端子を示す斜視図である。アルミニウム製の端子本体１ １は立方体状をなし、その長手方向の一端部にスリーブ１２が連結されている。 このスリーブ１２は円筒状をなし、その筒内に電線が圧縮固定されるようになっ ており、このスリーブ１２を介して電線と端子本体１１とが相互に電気的に接続 される。そして、端子本体１１の接続面には、はんだ１３により銅板１４が接合 されている。0004 FIG. 7 is a perspective view showing a conventional compression connection terminal. Aluminum terminal body 1 1 has a cubic shape, and a sleeve 12 is connected to one end in the longitudinal direction. This sleeve 12 has a cylindrical shape, and the electric wire is compressed and fixed inside the sleeve. The wire and the terminal body 11 are electrically connected to each other through the sleeve 12. be done. A copper plate 14 is bonded to the connection surface of the terminal body 11 by solder 13. has been done.
【０００５】 図８は実公昭６０−１３１７８号に開示された従来の圧縮接続端子を示す斜視 図である。この端子においては、銅板をはんだ付けする替わりに、アルミニウム 製の端子本体１１の全面に銅メッキ層１５が形成されている。[0005] FIG. 8 is a perspective view showing a conventional compression connection terminal disclosed in Utility Model Publication No. 60-13178. It is a diagram. In this terminal, instead of soldering a copper plate, an aluminum A copper plating layer 15 is formed on the entire surface of the terminal body 11 made of .
【０００６】 図９は実公平１−４０１２８号及び実公平２−３２５９号に開示された従来の 圧縮接続端子を示す斜視図である。この場合、端子本体１１に前処理を施すこと により、端子本体１１の接続面にのみ下地層１６が形成されており、この下地層 １６の表面に銅メッキ層１７が形成されている。[0006] Figure 9 shows the conventional technology disclosed in Utility Model Publication No. 1-40128 and Utility Model Publication No. 2-3259. It is a perspective view showing a compression connection terminal. In this case, the terminal body 11 should be pretreated. As a result, the base layer 16 is formed only on the connection surface of the terminal body 11, and this base layer A copper plating layer 17 is formed on the surface of 16.
【０００７】 なお、図７乃至図９においては、銅板１４及び銅メッキ層１５，１７の表面か ら端子本体１１を貫通する複数個のボルト孔が設けられていて、このボルト孔に ボルトを挿入し、このボルトを固定することにより、圧縮接続端子を所定の部材 に接続することができる。[0007] In addition, in FIGS. 7 to 9, the surface of the copper plate 14 and the copper plating layers 15 and 17 is A plurality of bolt holes are provided that pass through the terminal body 11, and the bolt holes are Insert a bolt and secure the bolt to attach the compression connection terminal to the specified member. can be connected to.
【０００８】[0008]
しかしながら、上述した従来の接続端子には以下に示す問題点がある。 However, the conventional connection terminal described above has the following problems.
【０００９】 先ず、端子本体の接続面に銅板１４をはんだ付けした接続端子においては、は んだ付けが物理的な接合方法であるため、銅板１４の平坦度及び接合時の加圧条 件に応じてその接合状態が異なると共に、はんだ付け時に溶融はんだ中の介在物 及び気泡により残渣が生じ、この残渣により端子本体１１と銅板１４との境界部 には未接合部分が残存する。このため、端子本体１１と銅板１４との間の接合強 度が不十分であるので、銅板１４が端子本体１１から剥離し、送電又は受電がで きなくなる虞がある。[0009] First, in the connection terminal in which the copper plate 14 is soldered to the connection surface of the terminal body, Since soldering is a physical joining method, the flatness of the copper plate 14 and the pressure conditions during joining are The joining condition differs depending on the situation, and inclusions in the molten solder occur during soldering. A residue is generated by the air bubbles, and this residue causes the boundary between the terminal body 11 and the copper plate 14 to There remains an unjoined part. Therefore, the bond between the terminal body 11 and the copper plate 14 is strengthened. Since the strength is insufficient, the copper plate 14 may peel off from the terminal body 11, making it impossible to transmit or receive power. There is a risk that it will not work.
【００１０】 また、端子本体１１の全面に銅メッキ層１５を形成した接続端子は、銅メッキ 液の消費量が多いため、接続端子の製造コストが高く、実生産上、好ましくない 。一方、端子本体１１の接続面にのみ銅メッキ層１７を形成した接続端子は、製 造コストを低減できるものの、端子本体１１と銅メッキ層１７とが実質的に平行 に接合されているため、曲げ応力が負荷されると、境界部分に引張応力が生じ、 これにより端子本体１１から銅メッキ層１７が剥離する場合がある。このため、 接続端子を屋外等で使用した場合、風力等により曲げ応力が負荷されると、銅メ ッキ層１７が剥離し、送電又は受電ができなくなる。0010 In addition, the connection terminal in which the copper plating layer 15 is formed on the entire surface of the terminal body 11 is copper-plated. Due to the large amount of liquid consumed, the manufacturing cost of connection terminals is high, which is not desirable in actual production. . On the other hand, the connection terminal in which the copper plating layer 17 is formed only on the connection surface of the terminal body 11 is manufactured Although the manufacturing cost can be reduced, the terminal body 11 and the copper plating layer 17 are substantially parallel to each other. When bending stress is applied, tensile stress is generated at the boundary, and This may cause the copper plating layer 17 to peel off from the terminal body 11. For this reason, When the connection terminal is used outdoors, the copper metal may become damaged if bending stress is applied due to wind force, etc. The coating layer 17 peels off, making it impossible to transmit or receive power.
【００１１】 本考案はかかる問題点に鑑みてなされたものであって、銅メッキ層の剥離を防 止できると共に、製造コストを低減できる接続端子を提供することを目的とする 。[0011] The present invention was developed in view of this problem, and is intended to prevent the copper plating layer from peeling off. The purpose is to provide a connection terminal that can be stopped and reduce manufacturing costs. .
【００１２】0012
本考案に係る接続端子は、アルミニウム又はアルミニウム合金で形成されその 一端面から導体が延びる端子本体と、この端子本体の接続面及びその前記一端面 の反対側の端面に形成された銅メッキ層とを有することを特徴とする。 The connection terminal according to the present invention is made of aluminum or aluminum alloy. A terminal body from which a conductor extends from one end surface, a connection surface of this terminal body, and the one end surface thereof. and a copper plating layer formed on the opposite end surface.
【００１３】[0013]
本考案においては、アルミニウム又はアルミニウム合金からなる端子本体の接 続面の外に、端子本体の導体接続端面と反対側の端面にも銅メッキ層が形成され ている。このため、この端子本体に対し、その長手方向（導体が延びる方向）に 曲げ応力が負荷され、銅メッキ層と端子本体との間に銅メッキ層を剥離する方向 の応力が作用しても、前記反対側の端面に形成された銅メッキ層により銅メッキ 層と端子本体との間に剥離限界応力を超える応力が作用することが防止される。 従って、銅メッキ層が端子本体から剥離することが回避される。 In this invention, the connection of the terminal body made of aluminum or aluminum alloy is In addition to the connection surface, a copper plating layer is also formed on the end surface of the terminal body opposite to the conductor connection end surface. ing. Therefore, for this terminal body, in the longitudinal direction (direction in which the conductor extends) The direction in which the copper plating layer is peeled off between the copper plating layer and the terminal body when bending stress is applied. Even when stress is applied, the copper plating layer formed on the opposite end surface Stress exceeding the peeling limit stress is prevented from acting between the layer and the terminal body. Therefore, peeling of the copper plating layer from the terminal body is avoided.
【００１４】 なお、銅メッキ層はメッキにより端子本体の接続面に化学的に接合されるため 、銅板をはんだ付けする従来の接続端子とは異なって未接合部分が存在すること はなく、端子本体と銅メッキ層との間の接合強度が高い。[0014] Note that the copper plating layer is chemically bonded to the connection surface of the terminal body by plating. , unlike conventional connection terminals in which copper plates are soldered, there is an unbonded part. The bonding strength between the terminal body and the copper plating layer is high.
【００１５】 また、銅メッキ層は端子本体の接続面及び前記反対側の端面にのみ形成されて いるため、端子本体の全面に銅メッキを施す従来の接続端子に比して、銅メッキ 液の消費量を低減でき、その製造コストを大幅に低減することができる。[0015] In addition, the copper plating layer is formed only on the connection surface of the terminal body and the opposite end surface. Therefore, compared to conventional connection terminals that have copper plating applied to the entire surface of the terminal body, copper plating is required. The amount of liquid consumed can be reduced, and the manufacturing cost can be significantly reduced.
【００１６】 このような銅メッキ層は、以下に示すようにして形成することができる。即ち 、端子本体の銅メッキ層を形成しない部分を樹脂等によりマスクした後、このマ スクを設けた端子本体をメッキ浴に浸漬する。これにより、端子本体の所定の部 分に銅メッキ層を選択的に形成することができる。[0016] Such a copper plating layer can be formed as shown below. That is, , mask the parts of the terminal body where the copper plating layer will not be formed with resin, etc., and then apply this mask. The terminal body provided with the mask is immersed in the plating bath. This allows the specified part of the terminal body to A copper plating layer can be selectively formed in minutes.

次に、本考案の実施例について添付の図面を参照して説明する。 Next, embodiments of the present invention will be described with reference to the accompanying drawings.
【００１８】 図１は本考案の実施例に係る圧縮接続端子を示す斜視図、図２は図１の破線部 Ａにおける部分拡大側面図である。[0018] Fig. 1 is a perspective view showing a compression connection terminal according to an embodiment of the present invention, and Fig. 2 is a portion shown in broken line in Fig. 1. It is a partially enlarged side view in A.
【００１９】 アルミニウム製の端子本体１は立方体状をなし、その長手方向の一端面にスリ ーブ２が連結されている。このスリーブ２は円筒状をなし、その筒内に電線が圧 縮固定されるようになっており、このスリーブ２を介して電線と端子本体１とが 相互に電気的に接続される。そして、端子本体１の接続面及び端子本体１の長手 方向の他端面、即ちスリーブ２が連結された一端面の反対側の端面（以下、他端 面という）には、下地層３が形成されており、この下地層３の表面に銅メッキ層 ４が形成されている。更に、銅メッキ層４の表面には錫メッキ層（又は銀メッキ 層）５が形成されている。[0019] The terminal body 1 made of aluminum has a cubic shape, and has a slot on one end surface in the longitudinal direction. pipe 2 is connected. This sleeve 2 has a cylindrical shape, and the electric wire is compressed inside the cylinder. The electric wire and the terminal body 1 are connected through this sleeve 2. electrically connected to each other. Then, the connection surface of the terminal body 1 and the longitudinal direction of the terminal body 1 The other end face in the direction, that is, the end face opposite to the one end face to which the sleeve 2 is connected (hereinafter referred to as the other end A base layer 3 is formed on the base layer 3, and a copper plating layer is formed on the surface of the base layer 3. 4 is formed. Furthermore, the surface of the copper plating layer 4 is coated with a tin plating layer (or silver plating). Layer) 5 is formed.
【００２０】 なお、銅メッキ層４の表面から端子本体１を貫通する複数個のボルト孔が設け られていて、このボルト孔にボルトを挿入し、このボルトを固定することにより 、圧縮接続端子を所定の部材に接続することができる。例えば、１対の圧縮接続 端子を相互接続する場合、その接続面を対向させてボルトにより固定する。[0020] Note that a plurality of bolt holes are provided that penetrate the terminal body 1 from the surface of the copper plating layer 4. By inserting a bolt into this bolt hole and fixing this bolt, , the compression connection terminal can be connected to a predetermined member. For example, a pair of compression connections When interconnecting terminals, their connection surfaces are opposed and fixed with bolts.
【００２１】 このように構成される圧縮接続端子においては、端子本体１の接続面から前記 他端面にまで延びるように銅メッキ層４が形成されているため、この端子本体１ の長手方向に曲げ応力が負荷されて銅メッキ層４を剥離する方向の応力が作用し ても、この応力が銅めっき層４の剥離限界応力を超えることを防止できる。この ため、銅メッキ層４が端子本体１から剥離することを回避できる。また、銅メッ キ層４は端子本体１の接続面及び特定の端面にのみ形成されているため、端子本 体１の全面に銅メッキを施す従来の圧縮接続端子に比して、銅メッキ液の消費量 を低減でき、その製造コストを大幅に低減することができる。[0021] In the compression connection terminal configured in this way, the connection surface of the terminal body 1 is Since the copper plating layer 4 is formed so as to extend to the other end surface, this terminal body 1 Bending stress is applied in the longitudinal direction of the copper plating layer 4, and stress acts in the direction of peeling off the copper plating layer 4. However, this stress can be prevented from exceeding the peeling limit stress of the copper plating layer 4. this Therefore, peeling of the copper plating layer 4 from the terminal body 1 can be avoided. Also, copper plated Since the protective layer 4 is formed only on the connection surface and specific end surfaces of the terminal body 1, The consumption of copper plating solution is lower than that of conventional compression connection terminals, which apply copper plating to the entire surface of body 1. can be reduced, and the manufacturing cost can be significantly reduced.
【００２２】 次に、実際に本実施例に係る圧縮接続端子を製造し、その耐剥離性を従来のも のと比較した結果について説明する。[0022] Next, we actually manufactured the compression connection terminal according to this example and tested its peel resistance compared to the conventional one. We will explain the results compared with
【００２３】 先ず、端子本体１の接続面及び前記他端面に塩化第一銅を塗布し、これをオー ブン炉内で焼成することにより、下地層３を形成した。次に、樹脂により端子本 体１のメッキ不要部分をマスキングした後、この端子本体１を硫酸銅浴に浸漬し 、液温が２５℃、電流密度が２Ａ／ｄｍ2 の条件にて銅メッキを施すことにより 、下地層３の表面に銅メッキ層４を形成した。その後、端子本体１のマスキング を除去した。このようにして、本実施例に係る圧縮接続端子を製造した。First, cuprous chloride was applied to the connection surface and the other end surface of the terminal body 1 and baked in an oven to form the base layer 3 . Next, after masking unnecessary parts of the terminal body 1 with resin, the terminal body 1 is immersed in a copper sulfate bath, and copper plating is applied at a liquid temperature of 25° C. and a current density of 2 A/dm 2 . As a result, a copper plating layer 4 was formed on the surface of the base layer 3. Thereafter, the masking of the terminal body 1 was removed. In this way, the compression connection terminal according to this example was manufactured.
【００２４】 また、下地層、銅メッキ層及び錫メッキ層の形成部分が異なること以外は、実 施例と同様にして、図９に示す従来の圧縮接続端子を製造した。なお、図３及び 図４に示すように、実施例及び従来例に係る圧縮接続端子はその長手方向の長さ をＬとした。[0024] In addition, except for the formation parts of the base layer, copper plating layer, and tin plating layer, the actual A conventional compression connection terminal shown in FIG. 9 was manufactured in the same manner as in the example. In addition, Figure 3 and As shown in FIG. 4, the compression connection terminal according to the embodiment and the conventional example has a length in the longitudinal direction. was set as L.
【００２５】 上述の実施例及び従来例に係る圧縮接続端子について、夫々曲げ角度及び曲げ 半径を変化させて屈曲させ、その耐剥離性を調べた。その結果を図５及び図６に 示す。なお、図５は本実施例を示すものであり、図６は従来例を示すものであっ て、図中において、剥離がない場合を○で示し、剥離がある場合を×で示した。[0025] Regarding the compression connection terminals according to the above-mentioned embodiment and conventional example, the bending angle and bending are respectively The peeling resistance was examined by bending the specimen with varying radius. The results are shown in Figures 5 and 6. show. Note that FIG. 5 shows this embodiment, and FIG. 6 shows a conventional example. In the figure, the case where there was no peeling is indicated by ◯, and the case where there was peeling is indicated by ×.
【００２６】 この図５及び図６から明らかなように、本実施例に係る圧縮接続端子は種々の 曲げ角度及び曲げ半径で屈曲させても、端子本体から銅メッキ層が剥離すること はなく、耐剥離性が優れていた。また、この圧縮端子に所定のヒートサイクル試 験を行なっても、特に異常はなかった。[0026] As is clear from FIGS. 5 and 6, the compression connection terminal according to this embodiment can be used in various ways. Even when bent at the bending angle and bending radius, the copper plating layer may peel off from the terminal body. The peeling resistance was excellent. In addition, this compression terminal should be subjected to the prescribed heat cycle test. There were no particular abnormalities during the tests.
【００２７】 一方、従来の圧縮接続端子は曲げ半径をＬ／２πにし、曲げ角度を１８０°に すると、端子本体の接続面の端部にて、端子本体と銅メッキ層との境界部分が剥 離した。[0027] On the other hand, conventional compression connection terminals have a bending radius of L/2π and a bending angle of 180°. Then, the boundary between the terminal body and the copper plating layer will peel off at the end of the connection surface of the terminal body. I let go.
【００２８】[0028]
以上説明したように本考案によれば、銅メッキ層をアルミニウム又はアルミニ ウム合金からなる端子本体の接続面及び導体が連結された端面の反対側の端面（ 他端面）に形成するから、端子本体の長手方向に曲げ応力が負荷されても、銅メ ッキ層が端子本体から剥離することを防止できる。従って、本考案に係る接続端 子は高品質であって、屋外等においても長期間安定して使用することができる。 As explained above, according to the present invention, the copper plating layer is made of aluminum or aluminum. The connection surface of the terminal body made of aluminum alloy and the end surface opposite to the end surface where the conductor is connected ( Since the copper plate is formed on the other end face), even if bending stress is applied in the longitudinal direction of the terminal body, the copper This prevents the coating layer from peeling off from the terminal body. Therefore, the connection end according to the present invention The material is of high quality and can be used stably for a long period of time even outdoors.
【００２９】 また、銅メッキ層は端子本体の接続面及び前記他端面にのみ形成するから、そ の製造コストを大幅に低減することができる。[0029] In addition, since the copper plating layer is formed only on the connection surface and the other end surface of the terminal body, can significantly reduce manufacturing costs.
