In the present embodiment, the case where the flat terminal 22a is formed to have a larger size and plate thickness than the flat terminal 22b will be described, but the present invention is not limited thereto. For example, the flat terminals 22a and 22b may be terminals of the same size when the applied voltage or current has the same magnitude.

複数の凸部２３ａ，２３ｂは、複数の平坦端子２２ａ，２２ｂのそれぞれの表面から外部に向かって突出する凸部として設けられている。複数の凸部２３ａ，２３ｂは、略円柱状に形成されている。例えば、凸部２３ａ，２３ｂは、図２に示すように、平坦端子２２ａ，２２ｂの押出成形等によって形成されている。凸部２３ａは、凸部２３ｂよりも大きく形成されている。 The plurality of convex portions 23a and 23b are provided as convex portions protruding outward from the surfaces of the plurality of flat terminals 22a and 22b. The plurality of convex portions 23a and 23b are formed in a substantially columnar shape.

The convex portion 23a is formed larger than the convex portion 23b.

複数の平坦端子２２ａは、図１及び図３に示すように、第２凸部２４を有する。第２凸部２４は、平坦端子２２ａの表面から外部に向かって突出する凸部として設けられている。第２凸部２４は、同一の方向に突出する凸部２３ａよりも小さく形成されている。第２凸部２４は、平坦端子２２ａの押出成形等によって形成されている。本実施形態では、第２凸部２４は、凸部２３ａよりも小さく形成される場合について説明するが、これに限定されない。例えば、第２凸部２４は、凸部２３ａと同一の大きさ、形状としてもよい。 The plurality of flat terminals 22a have a second convex portion 24 as shown in FIGS. 1 and 3. The second convex portion 24 is provided as a convex portion that protrudes outward from the surface of the flat terminal 22a. The second convex portion 24 is formed to be smaller than the convex portion 23a protruding in the same direction. The second convex portion 24 is formed by extrusion molding or the like of the flat terminal 22a. In the present embodiment, the case where the second convex portion 24 is formed smaller than the convex portion 23a will be described, but the present invention is not limited to this. For example, the second convex portion 24 may have the same size and shape as the convex portion 23a.

複数の配線部材３ａ，３ｂは、複数の平坦端子２２ａ，２２ｂと、複数の電線、ワイヤーハーネス等とを電気接続するための板状の導電性部材である。複数の配線部材３ａ，３ｂは、金属板にプレス加工等が施されて得られるものである。複数の配線部材３ａ，３ｂは、例えば、バスバー、絶縁被覆された板状の導体等を含む。配線部材３ａは、部品本体２１の上面２１ａにおいて平坦端子２２ａに重ねられ、側面２１ｃから外部に向かって延在されている。配線部材３ｂは、部品本体２１の上面２１ａにおいて平坦端子２２ｂに重ねられ、側面２１ｄから外部に向かって延在されている。すなわち、配線部材３ａと配線部材３ｂとは、反対の方向に向かって延在されている。 The plurality of wiring members 3a and 3b are plate-shaped conductive members for electrically connecting the plurality of flat terminals 22a and 22b to a plurality of electric wires, wire harnesses and the like. The plurality of wiring members 3a and 3b are obtained by pressing a metal plate or the like. The plurality of wiring members 3a and 3b include, for example, a bus bar, an insulatingly coated plate-shaped conductor, and the like. The wiring member 3a is overlapped with the flat terminal 22a on the upper surface 21a of the component main body 21, and extends outward from the side surface 21c. The wiring member 3b is overlapped with the flat terminal 22b on the upper surface 21a of the component main body 21 and extends outward from the side surface 21d. That is, the wiring member 3a and the wiring member 3b extend in opposite directions.

複数の配線部材３ａ，３ｂは、貫通孔３１ａ，３１ｂを有する。貫通孔３１ａは、平坦端子２２ａの凸部２３ａの外形と同じ形状で形成されている。貫通孔３１ｂは、平坦端子２２ｂの凸部２３ｂの外形と同じ形状で形成されている。本実施形態では、複数の平坦端子２２ａ，２２ｂの凸部２３ａ，２３ｂの外形が円形であるため、貫通孔３１ａ，３１ｂは、外径が円形の貫通孔として形成されている。貫通孔３１ａ，３１ｂは、挿入される平坦端子２２ａ，２２ｂの凸部２３ａ，２３ｂの外形に対応した形状の貫通孔として形成することができる。 The plurality of wiring members 3a and 3b have through holes 31a and 31b. The through hole 31a is formed in the same shape as the outer shape of the convex portion 23a of the flat terminal 22a. The through hole 31b is formed in the same shape as the outer shape of the convex portion 23b of the flat terminal 22b. In the present embodiment, since the outer shapes of the convex portions 23a and 23b of the plurality of flat terminals 22a and 22b are circular, the through holes 31a and 31b are formed as through holes having a circular outer diameter. The through holes 31a and 31b can be formed as through holes having a shape corresponding to the outer shape of the convex portions 23a and 23b of the flat terminals 22a and 22b to be inserted.

複数の配線部材３ａは、平坦端子２２ａの第２凸部２４が挿入される第２貫通孔３２をさらに有する。第２貫通孔３２は、平坦端子２２ａの第２凸部２４に挿入されることにより、配線部材３ａが平坦端子２２ａからずれたり、回転したりすることを防止できる。 The plurality of wiring members 3a further have a second through hole 32 into which the second convex portion 24 of the flat terminal 22a is inserted. By inserting the second through hole 32 into the second convex portion 24 of the flat terminal 22a, it is possible to prevent the wiring member 3a from shifting or rotating from the flat terminal 22a.

溶融部４は、配線部材３ａ，３ｂの貫通孔３１ａ，３１ｂに挿入された平坦端子２２ａ，２２ｂの凸部２３ａ，２３ｂの少なくとも一部が溶融され、凸部２３ａ，２３ｂと配線部材３ａ，３ｂとに跨がって設けられている。溶融部４は、凸部２３ａ，２３ｂと配線部材３ａ，３ｂとを溶着している。本実施形態では、溶融部４は、図１及び図２に示すように、凸部２３ａ，２３ｂにおける対向する２箇所が、レーザー溶接によって溶融された部分になっている。溶融部４は、凸部２３ａ，２３ｂを溶融したビードであり、凸部２３ａ，２３ｂと配線部材３ａ，３ｂとに跨がるように溶融されている。その結果、平坦端子２２ａ，２２ｂと配線部材３ａ，３ｂとは、溶融部４によって電気接続されている。平坦端子２２ａ，２２ｂの凸部２３ａ，２３ｂは、配線部材３ａ，３ｂより小さいため、配線部材３ａ，３ｂを溶融させるよりも、レーザー溶接におけるエネルギー量を小さくすることができる。 In the melting portion 4, at least a part of the convex portions 23a, 23b of the flat terminals 22a, 22b inserted into the through holes 31a, 31b of the wiring members 3a, 3b is melted, and the convex portions 23a, 23b and the wiring members 3a, 3b are melted.

In the present embodiment, as shown in FIGS. 1 and 2, the melting portion 4 has two facing portions of the convex portions 23a and 23b that are melted by laser welding. The melting portion 4 is a bead in which the convex portions 23a and 23b are melted, and is melted so as to straddle the convex portions 23a and 23b and the wiring members 3a and 3b. As a result, the flat terminals 22a and 22b and the wiring members 3a and 3b are electrically connected by the melting portion 4. Since the convex portions 23a and 23b of the flat terminals 22a and 22b are smaller than the wiring members 3a and 3b, the amount of energy in laser welding can be reduced as compared with melting the wiring members 3a and 3b.

本実施形態では、溶融部４は、凸部２３ａ，２３ｂに２箇所設ける場合について説明するが、これに限定されない。例えば、溶融部４は、凸部２３ａ，２３ｂの縁の全てを溶融させてもよいし、凸部２３ａ，２３ｂの１箇所または２箇所よりも多くの箇所としてもよい。溶融部４は、凸部２３ａ，２３ｂの表面における縁付近であることが好ましい。 In the present embodiment, the case where the melting portion 4 is provided at two locations on the convex portions 23a and 23b will be described, but the present invention is not limited to this. For example, the melting portion 4 may melt all the edges of the convex portions 23a and 23b, or may be more than one or two locations of the convex portions 23a and 23b. The melting portion 4 is preferably near the edge on the surface of the convex portions 23a and 23b.
