Description

Ｕ字形ブリッジ要素として特に適しているものは、適切に折り曲げられた金属ストリップ又は銅ストリップである。これは、一片の金属ストリップ、特に適切な長さの銅ストリップで、その２つの端部を斜線上に平坦に折り畳むことによって、簡単な方法で得られる（図３Ａ及び３Ｂ参照）。 Particularly suitable as a U-shaped bridge element is a properly bent metal strip or copper strip. This is a simple piece of metal strip, especially a copper strip of appropriate length, which can be obtained in a simple way by folding its two ends flat on diagonal lines (see Figures 3A and 3B).

図３Ａ及び３Ｂは、バスバーの２つの別個の銅ストリップ１２、１３を接続しているブリッジ要素１５を概略的に示す。図３Ａ及び図３Ｂは、図２Ｂの詳細図であり、図３Ａは、正面の立面図を示し、図３Ｂは背面の立面図を示す。別個の銅ストリップ１２、１３は、バスバーの構成要素として、銀層１９上に適用されている。２つの別個の銅ストリップ１２、１３の間の距離は、約５ｍｍである。ブリッジ要素は、同様に銅ストリップから作られている。ブリッジ要素１５用の銅ストリップは、両端領域で斜線上に平坦に折り畳まれ、Ｕ字型のブリッジ要素１５をもたらす。ブリッジ要素の一方の脚部は、別個の銅ストリップ１２に半田付けされており、他方の脚部は別個の銅ストリップ１３に半田付けされている。 3A and 3B schematically show a bridge element 15 connecting two separate copper strips 12, 13 of a bus bar. 3A and 3B are detailed views of FIG. 2B, FIG. 3A shows a front elevation view, and FIG. 3B shows a back elevation view. Separate copper strips 12, 13 are applied on the silver layer 19 as a component of the bus bar. The distance between the two separate copper strips 12, 13 is about 5 mm. The bridge element is also made from copper strips. The copper strip for the bridge element 15 folds flat on diagonal lines at both ends to provide a U-shaped bridge element 15. One leg of the bridge element is soldered to a separate copper strip 12, and the other leg is soldered to a separate copper strip 13.
