Waterproof structure and waterproof method for obstacle detection transmitter in architectural shutter device

摘要

PROBLEM TO BE SOLVED: To house a connector 14, connecting a substrate 13 of a transmitter 11 for obstacle detection provided to a seat plate 7 of a shutter curtain 2 to an obstacle detection switch 8, in a connector chamber 11f provided to the transmitter 11 in a high-waterproofness maintained state.SOLUTION: A connector chamber 11f is composed of: a bottom-side half part S1 formed in a recessed shape having a bottom and an opening at a lid 11c of a transmitter 11, and having a connector 14 placed therein, and an opening-side half part S2 where a cable 10 connected to the side of an obstacle detection switch 8 is led in. The connector chamber maintains high waterproofness by partitioning off the half parts with a detachable partition body 11k and then filling the opening-side half part S2 with a non-curable soft viscous waterproof material.SELECTED DRAWING: Figure 6
