ABSTRACT:
An electrical junction box may include a casing with a lower casing member and an upper casing member. A multi-layered circuit board may be retained in the electrical junction box. The multi-layered circuit board may contain a lower layer circuit board, an upper layer circuit board and an insulation plate that is disposed between and supports the lower layer circuit board and the upper layer circuit board. A rib and a boss may project from the lower casing member and may contact the insulation plate without contacting either the lower layer circuit board or the upper layer circuit board. In this manner, no physical stress is applied to a surface of either the lower layer circuit board or the upper layer circuit board thereby preventing detachment of an electronic component from the multi-layered circuit board.
