Abstract

PURPOSE:To completely eliminate an influence of a noise generated on the side of an electric power line to the side of a signal line by a method wherein the inside of a box is positioned by using a magnetic shielding plate and a lead-wire penetrating port is formed at a wall of each partitioned chamber. CONSTITUTION:Lead-wire penetrating ports 50, 50,... are formed at side walls 49 of a main body part 44; a female screw 52 is cut at the lead-wire penetrating port 50. Two each protrusions 76, 76 are formed at central parts of the facing side walls 49, 49 of the main body part of a joint box 36; a magnetic shielding plate 80 is inserted into recessed parts 78 between the two protrusions 76, 76. This shielding plate 80 shields nearly a whole face in a height direction of an inside space of the joint box 36 and divides the inside space into two partitions. Because electric power lines 40 and 42 which are wired 68 in a partition 82 are wiring parts for a heavy electric apparatus such as an electric motor, a large quantity of noises is generated. These noises are shielded completely by using the magnetic shielding plate 80, no noise is generated at a lead wire on the side of a signal line which is wired inside a partition 84.
