ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a wire-jointing assembly for a joint box, and more particularly to a wire-jointing assembly for a join box of a ceiling fan.
2. Description of the Related Art
It is common to install two sets of switches and a voltage-stabilizing rectifier in a joint box of a ceiling fan to control rotating speed and directions as well as stabilization of current or voltage. A considerable number of internal wires are required for connection with the fan motor, the wiring is thus complicated and the corresponding structures occupy a considerable space. Installation and maintenance are inconvenient and troublesome.
SUMMARY OF THE INVENTION
It is the primary object of the present invention to provide a wire-jointing assembly for a ceiling fan joint box that provides rapid connection and easy maintenance.
In accordance with the present invention, a wire-jointing assembly is provided for a joint box of the type comprising a casing securely attached to a support rod of a ceiling fan, the joint box further comprising a switch seat and electric control devices mounted in the casing. The wire-jointing assembly comprises:
a first wire-jointing seat attached to the support rod of the ceiling fan and including a plurality of first side slots that are communicated with outside, each said first side slot receiving a first wire that provides connection with the switch seat and the electric control devices; and
a second wire-jointing seat secured to the switch seat and including a plurality of second side slots that are communicated with outside, each said second side slot receiving a second wire that provides connection with the switch seat and the electric control devices, the first wire including a first contact, and the second wire including a second contact in electrical contact with the first contact of the first wire.
The first wire-jointing seat is L-shape having a vertical section and a horizontal section in the form of a ring through which the support rod of the ceiling fan extends. The vertical section of the first wire-jointing seat includes a plurality of vertically spaced grooves. The first side slots are defined in the vertical section and each first side slot is communicated with an associated groove via a hole. The first contact of the first wire extends into an associated groove when the first wire is inserted into the associated first side slot. The vertical section of the first wire-jointing seat includes a nut secured thereto for engaging with a threaded section of the support rod of the ceiling fan.
The second wire-jointing seat includes an opening that faces outside, and the second side slots are communicated with the opening. The switch seat and the second wire-jointing seat are slidable one relative to the other.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
