ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connector, and more particularly to a connector for connecting electric wires to prongs of a switch easily and quickly.
2. Description of Related Art
Electric switches turn electricity on or off to a device run by electricity. With reference to
FIG. 6
, a conventional electric switch (
20
) is adapted to electrically connect to two wires (
30
). The switch (
20
) has three prongs (
21
) to which wires (
30
) are electrically connected. The wire (
30
) has a conductor (
31
) that is adapted to conduct a current, and insulating material surrounds and isolates the conductor (
31
).
The conductor (
31
) of the electric wire (
30
) can be directly soldered to the prong (
21
). With further reference to
FIG. 7
, another method of attaching the wire (
30
) to the prong (
21
) is to define a threaded hole (not shown) in each prong (
21
). After winding the conductor (
21
) around a screw (
22
) with a head, the screw (
22
) is screwed into the threaded hole, and the screw (
22
) squeezes and holds the conductor (
31
) between the head of the screw (
22
) and the prong (
21
).
No matter which method is used, a tool such as a screwdriver or a soldering iron is always needed to attach the conductor (
31
) to the prong (
22
). Getting the tools and attaching the wire (
30
) to the switch (
20
) can be very inconvenient.
To overcome the shortcomings, the present invention provides a connector for connecting the electric wire to switch to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the invention is to provide a connector for connecting wire to switch quickly and easily.
Another objective of the invention is to provide a connector for connecting wire without using a tool.
