Document Type and Number:
Japanese Patent JPH08168119
Kind Code:
A
Abstract:
PURPOSE: To prevent dust from entering from the outside of a box body through an electric wire through part of a closed power distribution panel and to facilitate assembly.
CONSTITUTION: A hole part 2 for leading electric wire is formed at a box body 1 for housing electrical equipment and an electrical wire 4 passes through the hole part 2. A screening member is provided between the electric wire 4 and the hole part 2. The screening member is provided with a hollow member 7 consisting of rubber tube and is sandwiched by frame bodies 8 and 9. The hollow member 7 expands so that the electrical wire 4 is clamped after media such as air and water are injected inside the hollow member 7, thus screening the surrounding of the electrical wire 4.
