Description

本発明は、例えば互いに導電接続すべき給電側と受電側の電気機器または部材等を、相互間の熱応力や振動もしくは位置誤差等を吸収させ、或いは相対移動を許容した状態で電気的に接続する場合などに用いる可撓性接続端子に関する。   For example, the present invention electrically connects, for example, a power supply side and a power reception side electrical device or member to be electrically connected to each other in a state in which thermal stress, vibration, or positional error between them is absorbed or relative movement is allowed. The present invention relates to a flexible connection terminal used in the case of performing the above.

従来、上記のような可撓性接続端子として、多数の導電性金属薄板を積層してなる可撓導体の両端部に、導電性の金属端子を電磁波ビーム溶接等により導電接続したものは知られている（例えば下記特許文献１参照）。   Conventionally, as a flexible connection terminal as described above, one in which a conductive metal terminal is conductively connected to both ends of a flexible conductor formed by laminating a number of conductive metal thin plates by electromagnetic beam welding or the like is known. (For example, see Patent Document 1 below).

図６は上記のような可撓性接続端子１の一例を示すもので、銅箔等の多数の導電性金属薄板２１を積層してなる可撓導体２の両端部に、銅等の導電性金属よりなる端子ブロック３ａ，３ｂを突き合わせて電磁波ビーム溶接Ｗにより導電接続した構成である。なお、上記図６は可撓導体２の一端側に接続される端子ブロック３ａのみを示し、上記可撓導体２の他端側にも上記とほぼ同様の要領で端子ブロック３ｂが接続されているが、図には省略した。図中、Ｔは上記の電磁波ビーム溶接を施すための溶接トーチを示す。   FIG. 6 shows an example of the flexible connection terminal 1 as described above. Conductive materials such as copper are provided at both ends of a flexible conductor 2 formed by laminating a large number of thin conductive metal plates 21 such as copper foil. The terminal blocks 3a and 3b made of metal are brought into contact with each other and conductively connected by electromagnetic beam welding W. 6 shows only the terminal block 3a connected to one end side of the flexible conductor 2, and the terminal block 3b is connected to the other end side of the flexible conductor 2 in the same manner as described above. However, it was omitted in the figure. In the figure, T indicates a welding torch for performing the above-mentioned electromagnetic beam welding.

ところが、上記のように可撓導体２の端部に、端子ブロック３ａ，３ｂを突き合わせて電磁波ビーム溶接Ｗ等で導電接続する場合、１回の溶接で端子ブロック３ａ，３ｂと接合し得る可撓導体２の厚さ（図６で上下方向の高さ）は溶接機の容量や能力で決まり、例えば１回の溶接で接合できる深さが２５ｍｍであれば、図６のように上下両側から溶接しても最大で５０ｍｍの厚さの可撓導体が限界であり、それ以上の厚さの可撓導体は接合することができない。   However, when the terminal blocks 3a and 3b are brought into contact with the end portions of the flexible conductor 2 and conductively connected by electromagnetic beam welding W or the like as described above, the flexibility that can be joined to the terminal blocks 3a and 3b by one welding. The thickness of the conductor 2 (height in the vertical direction in FIG. 6) is determined by the capacity and capacity of the welding machine. For example, if the depth that can be joined by one welding is 25 mm, welding is performed from both the upper and lower sides as shown in FIG. Even so, a flexible conductor having a thickness of 50 mm at the maximum is the limit, and a flexible conductor having a thickness larger than that cannot be joined.

そのため、例えば可撓性接続端子の通電容量を増大させるために、可撓導体２を構成する導電性金属薄板２１の枚数を増やすと、それによって可撓導体２の全体厚さが増大して端子ブロック３ａ，３ｂに溶接接合することができない等の不具合があった。そこで、容量や能力の大きな溶接機を用いることが考えられるが、そのような溶接機は、それ自体が高価で費用が嵩むだけでなく、給電設備や安全対策にも多大な労力や設備が必要で製作コストが大幅に増大する等の問題があった。また、図６のような可とう導体を複数重ねて使用する方法もあるが、導体間に接触抵抗が発生するため、通電ロスとなる問題がある。   Therefore, for example, in order to increase the current carrying capacity of the flexible connection terminal, if the number of the conductive metal thin plates 21 constituting the flexible conductor 2 is increased, the total thickness of the flexible conductor 2 is thereby increased and the terminal is increased. There were problems such as being unable to weld-join the blocks 3a and 3b. Therefore, it is conceivable to use a welding machine having a large capacity and capacity. However, such a welding machine is not only expensive and expensive in itself, but also requires a lot of labor and equipment for power supply equipment and safety measures. However, there were problems such as a significant increase in production costs. Further, there is a method of using a plurality of flexible conductors as shown in FIG. 6, but there is a problem that a contact resistance is generated between the conductors, resulting in an energization loss.

本発明は上記の問題点に鑑みて提案されたもので、可撓導体の全体厚さが増大しても容易に端子ブロックと接合することのできる通電特性の優れた可撓性接続端子を提供することを目的とする。   The present invention has been proposed in view of the above problems, and provides a flexible connection terminal having excellent current-carrying characteristics that can be easily joined to a terminal block even when the total thickness of the flexible conductor increases. The purpose is to do.

上記の目的を達成するために本発明による可撓性接続端子は、以下の構成としたものである。すなわち、多数の導電性金属薄板を積層してなる可撓導体の両端部に導電性の金属よりなる端子ブロックを電磁波ビーム溶接または摩擦撹拌接合により導電接続した可撓性接続端子において、上記各端子ブロックの可撓導体接続側端部に複数の段部を階段状に形成し、その各段部に所定厚さの可撓導体を電磁波ビーム溶接または摩擦撹拌接合により導電接続したことを特徴とする。   In order to achieve the above object, a flexible connection terminal according to the present invention has the following configuration. That is, in the flexible connection terminal in which a terminal block made of conductive metal is conductively connected to both ends of a flexible conductor formed by laminating a large number of conductive metal thin plates by electromagnetic beam welding or friction stir welding, each of the above terminals A plurality of step portions are formed in a step shape on the end of the block on the side where the flexible conductor is connected, and a flexible conductor having a predetermined thickness is conductively connected to each step portion by electromagnetic beam welding or friction stir welding. .

上記のように可撓導体の両端部に接続される端子ブロックの可撓導体接続側端部に複数の段部を階段状に形成し、その各段部に所定厚さの可撓導体を電磁波ビーム溶接または摩擦撹拌接合により導電接続するようにしたことによって、可撓導体の全体厚さが増大しても上記各段部毎に所定厚さの可撓導体を端子ブロックに容易に接合することができる。その結果、例えば通電容量の大きな可撓性接続端子にあっても容易・安価に製作することが可能となる。   As described above, a plurality of step portions are formed in a step shape at the end portion of the terminal block connected to the both ends of the flexible conductor, and a flexible conductor having a predetermined thickness is formed on each step portion. By conducting conductive connection by beam welding or friction stir welding, even if the total thickness of the flexible conductor increases, a flexible conductor of a predetermined thickness can be easily joined to the terminal block for each step. Can do. As a result, it is possible to easily and inexpensively manufacture even a flexible connection terminal having a large current carrying capacity, for example.

なお、上記両端子ブロックの階段状の段部は、互いに対向させて設け、その互いに対向する段部の間隔をほぼ一定に形成して、その各対向する段部間にほぼ一定長さの可撓導体を導電接続するように構成するとよい。そのようにすると、上記一方の端子ブロックから他方の端子ブロックに上記各可撓導体を介して流れる電流の抵抗がほぼ一定となって、電流の片寄りや、局部的な発熱を防止することが可能となる。   The stepped step portions of both terminal blocks are provided so as to face each other, and the interval between the step portions facing each other is formed to be substantially constant, and a substantially constant length is allowed between the facing step portions. The flexible conductor may be configured to be conductively connected. As a result, the resistance of the current flowing from the one terminal block to the other terminal block via the flexible conductors becomes substantially constant, thereby preventing the deviation of the current and local heat generation. It becomes possible.

以下、本発明を図に示す実施形態に基づいて具体的に説明する。図１（ａ）は本発明による可撓性接続端子の一実施形態を示す平面図、（ｂ）はその正面図、図２は上記可撓性接続端子の一部の分解縦断面図であり、前記図６の従来例と同様の機能を有する部材には同一の符号を付して省略する。   Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings. 1A is a plan view showing an embodiment of a flexible connection terminal according to the present invention, FIG. 1B is a front view thereof, and FIG. 2 is an exploded longitudinal sectional view of a part of the flexible connection terminal. The members having the same functions as those of the conventional example shown in FIG.

本実施形態の可撓性接続端子１は、図１および図２に示すように銅箔やアルミニウム箔等の可撓性を有する多数の導電性金属薄板２１を積層してなる所定厚さの複数個の可撓導体２と、それらの可撓導体２の両端部に接続される銅やアルミニウム等の導電性金属よりなる端子ブロック３ａ，３ｂとよりなる。その各端子ブロック３ａ，３ｂの可撓導体２を接続する側の端部に複数の段部３１を階段状に形成し、その各段部３１に所定厚さの可撓導体２を電磁波ビーム溶接により導電接続したものである。   As shown in FIGS. 1 and 2, the flexible connection terminal 1 of the present embodiment has a plurality of predetermined thicknesses formed by laminating a large number of conductive thin metal plates 21 having flexibility such as copper foil and aluminum foil. Each of the flexible conductors 2 and terminal blocks 3 a and 3 b made of a conductive metal such as copper or aluminum are connected to both ends of the flexible conductors 2. A plurality of step portions 31 are formed in a step shape at the end portion of each terminal block 3a, 3b on the side where the flexible conductor 2 is connected, and the flexible conductor 2 having a predetermined thickness is welded to each step portion 31 by electromagnetic wave beam welding. Are conductively connected.

特に図の実施形態は図１（ｂ）に示すように両端子ブロック３ａ，３ｂの階段状の段部３１を互いに対向させて設け、その互いに対向する段部３１，３１間の間隔をほぼ一定に形成して、その各対向する段部３１，３１間にほぼ一定長さの可撓導体２を電磁波ビーム溶接により導電接続したものである。その電磁波ビーム溶接としては、例えば電子ビーム溶接、レーザービーム溶接、またはプラズマ溶接等を適用することができる。図中、３０は上記各端子ブロック３ａ，３ｂを不図示の電気機器や部材等に取付けるための取付孔である。   In particular, in the embodiment shown in the figure, stepped step portions 31 of both terminal blocks 3a and 3b are provided so as to face each other as shown in FIG. 1B, and the interval between the stepped portions 31 and 31 facing each other is substantially constant. The flexible conductor 2 having a substantially constant length is conductively connected by electromagnetic wave beam welding between the opposed step portions 31 and 31. As the electromagnetic wave beam welding, for example, electron beam welding, laser beam welding, or plasma welding can be applied. In the figure, reference numeral 30 denotes a mounting hole for mounting each of the terminal blocks 3a, 3b to an electric device or member (not shown).

なお、上記のように所定厚さに積層した可撓導体２を各段部３１に導電接続する場合、上下に隣り合う可撓導体２・２間には、必要に応じて例えば図１（ｂ）および図２に示すように適宜の間隔を有する隙間Ｓを設けるようにしてもよい。そのようにすると、可撓導体２と端子ブロック３ａ，３ｂとを電磁波ビーム溶接Ｗ等により接続した際、その溶接部Ｗの表面の溶接ビードを除去することなく各可撓導体２を良好に溶接することができる。   In addition, when the flexible conductor 2 laminated | stacked by the predetermined thickness as mentioned above is electrically connected to each step part 31, between the flexible conductors 2 * 2 adjacent to the upper and lower sides, for example, FIG. ) And a gap S having an appropriate interval may be provided as shown in FIG. By doing so, when the flexible conductor 2 and the terminal blocks 3a and 3b are connected by the electromagnetic wave beam welding W or the like, the respective flexible conductors 2 are well welded without removing the weld bead on the surface of the welded portion W. can do.

次に、上記のような可撓性接続端子１を製造するプロセスは適宜であるが、例えば以下の要領で製造すればよい。図３および図４はその一例を示すもので、先ず、図３（ａ）に示すように端子ブロック３ａの階段状の複数の段部３１のうち最下位の段部３１に可撓導体２の端部を溶接接合させる。そして上記段部３１の立ち上がり部と上記可撓導体２の端面との溶接接合部に沿って溶接トーチＴを移動させながら上記の溶接接合部を電磁波ビーム溶接Ｗにより接合して上記端子ブロック３ａと可撓導体２とを導電接続する。   Next, the process for manufacturing the flexible connection terminal 1 as described above is appropriate. For example, the flexible connection terminal 1 may be manufactured in the following manner. FIG. 3 and FIG. 4 show an example. First, as shown in FIG. 3A, the flexible conductor 2 is placed on the lowest step 31 among the plurality of stepped steps 31 of the terminal block 3a. The ends are welded together. Then, while moving the welding torch T along the weld joint between the rising portion of the step portion 31 and the end face of the flexible conductor 2, the weld joint is joined by the electromagnetic wave beam welding W, and the terminal block 3a. Conductive connection is made to the flexible conductor 2.

その際、上記可撓導体２を構成する金属薄板２１の積層厚さは、上記の電磁波ビーム溶接による１回の溶接工程で接合可能な厚さとする。また上記可撓導体２の積層厚さと、段部３１の立ち上がり部の高さは図示例のようにほぼ同等に形成すると、電磁波ビームが可撓導体２と端子ブロックとにバランスよく照射されて両者を良好に溶接接合することができる。   At that time, the laminated thickness of the thin metal plates 21 constituting the flexible conductor 2 is set to a thickness that can be joined in one welding process by the electromagnetic wave beam welding. Further, if the thickness of the flexible conductor 2 and the height of the rising portion of the step portion 31 are formed substantially equal to each other as shown in the figure, the electromagnetic wave is irradiated to the flexible conductor 2 and the terminal block in a balanced manner. Can be well welded together.

上記のようにして端子ブロック３ａの最下位の段部３１に可撓導体２を導電接続したら図３（ｂ）のように次の段部３１に可撓導体２を上記と同様の要領で導電接続して行く。そして図３（ｃ）のように端子ブロック３ａの全ての段部３１に可撓導体２を導電接続したら、同図（ｄ）のように上下反転する。   When the flexible conductor 2 is conductively connected to the lowest step portion 31 of the terminal block 3a as described above, the flexible conductor 2 is conductive to the next step portion 31 in the same manner as described above as shown in FIG. Go connect. When the flexible conductor 2 is conductively connected to all the step portions 31 of the terminal block 3a as shown in FIG. 3C, it is turned upside down as shown in FIG.

次いで、図４に示すように上記端子ブロック３ａを接続した可撓導体２の反対側の端部に、もう一方の端子ブロック３ｂを接続するもので、その場合にも図４（ａ）〜（ｃ）のように下側の可撓導体２から順に溶接Ｗすると、その複数の可撓導体２と上記端子ブロック３ｂとを容易に導電接続することができる。   Next, as shown in FIG. 4, the other terminal block 3b is connected to the opposite end of the flexible conductor 2 to which the terminal block 3a is connected. When welding W is sequentially performed from the lower flexible conductor 2 as in c), the plurality of flexible conductors 2 and the terminal block 3b can be easily conductively connected.

そして上記図４（ｃ）のように複数の可撓導体２の両端部に端子ブロック３ａと３ｂとを導電接続したところで、同図（ｄ）のように上下反転すれば、前記図１に示すような可撓性接続端子１が得られるものである。   Then, when the terminal blocks 3a and 3b are conductively connected to both ends of the plurality of flexible conductors 2 as shown in FIG. 4 (c) above, if they are turned upside down as shown in FIG. Such a flexible connection terminal 1 is obtained.

なお、上記実施形態は、端子ブロック３ａ，３ｂと可撓導体２とを電磁波ビーム溶接によって導電接続したが、摩擦撹拌接合によって導電接続してもよく、その場合にも上記と同様の作用効果が得られる。   In the above embodiment, the terminal blocks 3a and 3b and the flexible conductor 2 are conductively connected by electromagnetic beam welding. However, they may be conductively connected by friction stir welding. can get.

上記のようにして製造した可撓性接続端子１の各種電気機器や部材等への取付方法や取付手段は適宜であるが、例えば図５に示すように各種電気機器や部材Ｍ１，Ｍ２等に植設した取付ボルトＢに、前記各端子ブロック３ａ，３ｂに形成した取付孔３０を挿通嵌合して、上記取付ボルトＢにナットＮをねじ込むようにすれば容易に取付けることができる。その場合、可撓導体２を図５のように屈曲した状態で取付けると、例えば上記部材Ｍ１，Ｍ２間に図５で左右いずれの方向に振動やずれが生じても、それらを良好に吸収することが可能となる。   The flexible connecting terminal 1 manufactured as described above is appropriately attached to various electric devices and members, and the attaching means is appropriate. For example, as shown in FIG. The mounting bolts B can be easily mounted by inserting and fitting the mounting holes 30 formed in the terminal blocks 3a and 3b into the mounting bolts B so that the nuts N are screwed into the mounting bolts B. In that case, if the flexible conductor 2 is attached in a bent state as shown in FIG. 5, for example, even if vibration or displacement occurs in the left or right direction in FIG. 5 between the members M1 and M2, they are absorbed well. It becomes possible.

以上のように本発明による可撓性接続端子は、端子ブロックの可撓導体接続側端部に複数の段部を階段状に形成して、その各段部の立ち上が部もしくは立ち下がり部に可撓導体を突き合わせて電磁波ビーム溶接または摩擦撹拌接合により導電接続するようにしたから、可撓導体の全体厚さが増大しても容易に端子ブロックと接合することができる。その結果、多数の金属薄板を積層した通電容量の大きな可撓性接続端子にあっても溶接機の容量や能力を増大させることなく、容易・安価に製作することが可能となり、産業上の利用可能性を高めることができる。   As described above, in the flexible connection terminal according to the present invention, a plurality of step portions are formed in a step shape at the end of the terminal block on the flexible conductor connection side, and the rising of each step portion is a portion or a falling portion. Since the flexible conductor is brought into contact with each other and conductively connected by electromagnetic beam welding or friction stir welding, the terminal block can be easily joined even if the total thickness of the flexible conductor increases. As a result, it is possible to manufacture easily and inexpensively without increasing the capacity and capacity of the welding machine, even for flexible connection terminals with a large current carrying capacity made by laminating a large number of thin metal plates. The possibility can be increased.
