## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a wire connector, and more particularly relates to a fast wire connector capable of assembling or disassembling two electrical wires.
2. Description of the Related Art
In the conventional technique, two electrical wires can be connected by using a connector. Two ends of the connector respectively include a top hole and a bottom hole, and an interior of the connector includes a metal spring plate. Two conductive portions respectively disposed at a front end of each of the two electrical wires are plugged into the top hole and the bottom hole. After the two electrical wires are plugged into the top hole and the bottom hole, the conductive portions of the electrical wires are held by the metal spring plate and an inner surface of the connector to achieve an electrical connection between the conductive portions of the electrical wires and the metal spring plate. However, the size of the connector is small, and a length of the top hole or the bottom hole is limited. Therefore, after the electrical wire is plugged into the top hole or the bottom hole, the conductive portion of the electrical wire may be still exposed outside of the connector to cause power leakage or risk of electric shock. Moreover, the connector can fast connect the two electrical wires, but it is inconvenient to disassemble the electrical wires from the connector. The connector is required to be torn apart to disassemble the electrical wire and time is wasted. Therefore, to design an apparatus capable of quickly assembling or disassembling the two electrical wires is a significant issue in the conventional electronic devices.

DETAILED DESCRIPTION OF THE INVENTION
These and other aspects of the embodiments herein will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings.
With reference to FIG. 1 and FIG. 3 showing a first embodiment of the fast wire connector of the present invention, the fast wire connector includes a body 10 and a conductive sheet 20. The body 20 is a hollow body and includes a top surface 11, a bottom surface 12, a front side surface 13 and a rear side surface 14. The top surface 11 and the bottom surface 12 are disposed at two ends of the body 10, and the front surface 13 and the rear surface 14 are disposed at two sides of the body 10. A connecting space 15, a top housing chamber 16 and a bottom housing chamber 17 are formed within the body 10. The connecting space 15 includes a top hole 151, a bottom hole 152, and a housing chamber 153. The top hole 151 and the bottom hole 152 are respectively formed through the top surface 11 and the bottom surface 12, and the housing chamber 153 communicates with the top hole 151 and the bottom hole 152. Two stopper portions 105 are formed on the inner surface of the body 10 adjacent to the top housing chamber 16 and the bottom housing chamber 17 respectively. The two stopper portions 105 have two stopper surfaces respectively corresponding to the top hole 151 and the bottom hole 152.
With reference to FIG. 2, the body 10 comprises a first assembly 101 and a second assembly 102 capable of being coupled to each other. The first assembly 101 can be a shell and the second assembly 102 can be a cover. The connecting space 15 is formed between the shell and the cover. The front side surface 13 is included in the first assembly 101 and the rear side surface 14 is included in the second assembly 102. The top housing chamber 16 and the bottom housing chamber 17 are curved concavities and are respectively adjacent to the top surface 11 and the bottom surface 12.
The conductive sheet 20 is disposed within the housing chamber 153 of the connecting space 15. The conductive sheet 20 is a metal slim sheet shaped into S shape. The conductive sheet 20 is formed by bending two ends of a rectangular sheet and sequentially includes a top contact portion 21, a top bending portion 23, a bottom bending portion 24, and a bottom contact portion 22. The top contact portion 21 connects with the top bending portion 23, and the bottom contact portion 22 connects with the bottom bending portion 24. The top bending portion 23 is inserted into the top housing chamber 16 and contacts an inner surface of the body. The bottom bending portion 24 is inserted into the bottom housing chamber 17 and contacts the inner surface of the body 10. The top contact portion 21 and the bottom contact portion 22 respectively contact opposite inner surfaces of the body 10. An elongate through-hole 131 is extendedly formed on the front side surface 13 at a position corresponding to the top contact portion 21. Another elongate through-hole 131 is extendedly formed on the front side surface 13 at a position corresponding to the bottom contact portion 22.
With reference to FIG. 1 and FIG. 3, the present invention can provide two electrical wires 40 respectively inserted into the top hole 151 and the bottom hole 152, so the two electrical wires 40 can be electrically connected to each other. The electrical wire 40 includes an insulating portion 41 and a wire conductor insulated by the insulating portion 41. The wire conductor has a terminal as a conductive portion 42 uncovered by the insulating portion 41. When the two electrical wires 40 are respectively inserted into the top hole 151 and the bottom hole 152, the two conductive portions 42 of the two electrical wires 40 pushes down the top contact portion 21 and the bottom contact portion 22 and are positioned by contacting the stopper portions 105. Two ends of the top contact portion 21 and the bottom contact portion 22 respectively work with the inner surface of the body 10 to hold the conductive portion 42 of the electrical wire 40. Therefore, the two electrical wires 40 are assembled together and cannot be departed from each other. The two electrical wires 40 are electrically connected by contacting the conductive sheet 20 so as to achieve a fast wiring purpose. It should be noted that at a distance between the stopper portion 105 corresponding to the top hole 151 and the top surface 11 or a distance between the stopper portion 105 corresponding to the bottom hole 152 and bottom surface 12 includes a certain length to let a portion of the insulating portion 41 of the conductive portion 42 be disposed within the housing chamber 153. The length of a portion of the insulating portion 41 is longer than 4 mm. Therefore, when the electrical wire 40 is implemented in the present invention, the conductive portion 42 is completely covered by the body 10 and will not be located at the exterior of the housing chamber 153 to cause power leakage problem.
With reference to FIG. 3 to FIG. 5, when the electrical wire 40 is plugged into the top hole 151, a pencil-like tool 43 is inserted into a top edge of the elongate through-hole 131 on the front side surface 13. A front end of the pencil-like tool 43 contacts a top of the top contact portion 21. Afterwards, the pencil-like tool 43 is pulled down as shown in FIG. 5 and the front end of the pencil-like tool 43 pushes down the top contact portion 21. Therefore, the electrical wire 40 is no longer held between the front end of the top contact portion 21 and the inner surface of the body 10. The electrical wire 40 is easy to be released from the connector and the purpose to fast dissemble the electrical wire is achieved.

Moreover, in a different embodiment, the assembling components 141 are formed at two side wall surfaces of the rear side surface 14 and corresponding to the positions of the passing holes 132. As shown in FIG. 2, the two assembling components 141 of the fast wire connector at left hand side can be inserted into the two passing holes 132 of the fast wire connector at right hand side to assemble the connector. Therefore, the assembling structure can be used to extend the fast wire connector in the present invention.
With reference to FIG. 7 and FIG. 8, the body 10 of the fast wire connector in the present invention includes a left side surface 18 and a right side surface 19.

Compared with the conventional technique, the two elongate through-holes 131 are formed on the front side surface 13 of the body 10 corresponding to the conductive sheet 20 in the present invention. After the pencil-like tool 43 is inserted into a top edge of the top elongate through-hole 131 and moves downward, a front end of the pencil-like tool 43 pushes down the top contact portion 21 to release the front end of the top contact portion 21 from the inner surface of the body 10 so as to remove the electrical wire. Therefore, the purpose to fast dissemble the electrical wire 40 is achieved. In addition, a certain length exists between a stopper portion 105 and the corresponding top hole 151 or the bottom hole 152 to let a portion of the insulating portion 41 of the electrical wire 40 remain disposed within the housing chamber 153. Therefore, when the electrical wire 40 is used in the present invention, the conductive portion 42 is not exposed outside of the housing chamber 153 to cause power leakage problem. Therefore, the present invention solves the problems of wire dissembling difficulty and power leakage in the conventional art.
