Wiring-device mounting structure |
摘要 |
A wiring-device mounting structure wherein outer decorative and inner laying plates are coupled to each other through relatively short, hooked engaging projections on inner surface of the decorative plate which are engaged with mounds on the laying plate which are raised to be close at raised top face to the inner surface of the decorative plate when coupled and to provide at side wall a locking face for hooked ends of the projections, whereby the raised mounds positioned in coupling zone between the both plates can minimize coupling distance between them and also the length of the engaging projections, so as to maintain the projections to be highly durable.
