Abstract: Provided is a flexible circuit board installed on a frame to which a bus bar is coupled. The flexible circuit board may include a central portion having a band shape, first connection circuit portions formed at both ends of the central portion and disposed to face each other, second connection circuit portions extending from the first connection circuit portions in parallel with the central portion, and third connection circuit portions extending from the first connection circuit portions and the second connection circuit portions and connected to the bus bar. An overlapped may be formed when each of the second connection circuit portions is folded toward one side of each of the first connection circuit portions.

Abstract: A heat dissipation printed circuit board includes a metal core, lower and upper insulating layers, first lower and first upper circuit patterns, and second lower and second upper circuit patterns. The lower and upper insulating layers are disposed at a lower side and an upper side of the metal core, respectively. The first lower and first upper circuit patterns are disposed at a lower side of the lower insulating layer and at an upper side of the upper insulating layer, respectively. The second lower and second upper circuit patterns are disposed at a lower side of the first lower circuit pattern and at an upper side of the first upper circuit pattern, respectively. An etching portion in the first lower circuit pattern is filled with the lower insulating layer and an etching portion in the first upper circuit pattern is filled with the upper insulating layer.

Abstract: A junction box for a vehicle is provided. The junction box includes at least one printed circuit board having a metal core and a heat transfer member formed at an edge of the printed circuit board. In addition, the junction box includes a case in which at least one printed circuit board is disposed. Further, the heat transfer member contacts the inner surface of the case.
