Abstract

An easily disassemblable separate ceiling fan switch box structure which makes the upper cover and the lower housing body of the switch box locked and joined. Its upper cover can join to a wire distribution receptacle which connects to the wires of the elements of the switch device. The said wire distribution receptacle can couple with the wire distribution receptacle connected to the wires of the ceiling fan motor and then a fixing sleeve ring fixes and joins them. Further an annular or frame-shaped PC board can also be installed in the inner part of the lower housing body to allow the said elements and their wire distribution receptacle to be directly installed thereon, hereby making the ceiling fan switch box structure simplified and compact for convenient disassembly or assembly.

Claims

1. A disassemblable ceiling fan switch box structure of the type for housing therein electrical components of a ceiling fan having electrical wires, in combination, comprising:

an upper cover, the center of which has an inwardly extending flange, and further having a through screw hole formed in the center of said flange;

two or more positioning plates positioned on the inner circumference of said upper cover, each of said positioning plates having a screw hole formed therein;

a lower housing body for receiving therein the electrical components and the electrical wires thereof, said lower housing body having two or more positioning holes formed therein corresponding to the positioning plates;

a first hollow distribution receptacle being substantially cylindrical in shape, having a middle section of enlarged diameter and defining therebelow a lower section of reduced diameter, said middle section and said lower section being threaded on the outer surface thereof;

insulation disposed in said first receptacle;

a second hollow distribution receptacle being substantially cylindrical in shape, and having a middle section of enlarged diameter, said second receptacle having a screw hole formed therein;

insulation disposed in said second receptacle;

a hollow fixing sleeve ring being substantially cylindrical in shape, said sleeve ring being threaded on the inner surface thereof and having an upper end of reduced internal diameter;

said second receptacle being received in the fixing sleeve ring, whereby the middle section of the second receptacle abuts the upper end of the fixing sleeve ring;

said first receptacle being received in the fixing sleeve ring, whereby the middle section of the first receptacle threadily engages the interior of the fixing sleeve ring;

said first receptacle being received in and threadily engaging the screw hole of the upper cover;

whereby the wires of the electrical components are disposed within the screw hole, first receptacle, and second receptacle respectively.
