PROBLEM TO BE SOLVED: To surely form an electric circuit even after long-term repeated use by providing a finger type projection, which overhangs in a cantilever form in parallelly arranged opened holes and is bent so as to project its end parts outward from the surfaces of a circuit board respectively. SOLUTION: In respective finger type projections 26a, 26b in an electrical connector 18, respective tip parts 28a, 28b are bent at an angle θ so as to protrude from opened holes 24a, 24b. The tip parts 28a, 28b of the finger type projections are protruded outward beyond upper and lower faces 14, 16 of a circuit board 12. The tip part 28a is extended by a flexible distance 32a beyond the circuit board lower face 16, while the tip part 28b is extended by a flexible distance 32b beyond the upper face 14a. When an electric appliance is engaged on the circuit board 12, the finger type projection 26 in the electrical connector 18 is pushed down. In this way, the tip part 28 of the finger type projection 26 is moved through the flexible distance 32 so as to be positioned in the position shown by the warped finger type projections 288', 28b'. Based on this engagement, each connector 18 in an array body forms individuall electric circuit between electrical appliances. |
