The locating slot 90a of the case 90 is formed in a direction or a position along the X-direction reference axis.

(27) In a preferred embodiment, the restriction body 20 is integrally formed (or assembled) on the main body 10. The restriction body 20 is selectively made of an electro-conductive (metal) material and disposed on the first section 11 of the main body 10. The restriction body 20 has a base section 25 connected with the main body 10 (or the first section 11), a first arm 21 and a second arm 22 connected with the base section 25 and free sections 23, 24 connected with the first and second arms 21, 22, which together provide elastic effect for the restriction body 20.

(28) To speak more specifically, the first and second arms 21, 22 are respectively bent from the base section 25 to gradually obliquely extend toward each other along the X-direction reference axis (or in a direction normal to the plug-in direction of the conductive wire 80). The first and second arms 21, 22 define a mouth section 26 with a triangular configuration. A bent section 27, 28 is formed between each of the first and second arms 21, 22 and the free sections 23, 24, whereby the free section 23 of the first arm 21 and the free section 24 of the second arm 22 are bent to extend away from each other so as to define an opening 29, whereby the restriction body 20 can be elastically expanded to hold different diameters of conductive wires 80. As shown in the drawings, the opening 29 is open to the upper side (or along the X-direction reference axis).

(29) FIGS. 1, 2 and 3 also show that wing sections 21a, 22a respectively protrude from the first and second arms 21, 22 of the restriction body 20 and diverge to outer side of the restriction body 20 in a direction to the conductive wire 80 plugged into the case 90 or the wire plug-in hole 92 (or along the Z-direction reference axis). The wing sections 21a, 22a serve to help in guiding the conductive wire 80 to enter the conductive component.

(30) In this embodiment, the metal leaf spring 30 is a substantially V-shaped structure including a first section 31, a second section 32 and a bow section 33 connected between the first and second sections 31, 32. The first section 31 has a head end 34 secured in a locating hole 14 of the case 90 or the main body 10. The bow section 33 is assembled on a stake 93 of the case 90 or the chamber 91, whereby the tail end 35 of the second section 32 can be elastically biased to press the conductive wire 80. As shown in the drawings, the locating hole 14 is disposed on the second section 12 of the main body.

(31) The drawings also show the structures of the restriction body 20 and the aid unit 40 assembled with each other. The aid unit 40 is a U-shaped structure having an (arched) base 45, a first waist section 41 and a second waist section 42 connected with the base 45 and finger sections 43, 44 connected with the first and second waist sections 41, 42, which together define a space 46 with an opening 49, whereby the aid unit 40 can provide an elastic (holding) effect.

(32) To speak more specifically, the first and second waist sections 41, 42 are respectively bent from two ends of the base 45 to extend along the X-direction reference axis (or in a direction normal to the plug-in direction of the conductive wire 80). The first and second waist sections 41, 42 are further bent toward each other along the Y-direction reference axis to form the finger sections 43, 44. The base 45 of the aid unit 40 is assembled on a locating section 94 of the case 90 (or the chamber 91) in the form of a plate-like structure). The finger sections 43, 44 contact or latch with the bent section 27 of the first arm and the bent section 28 of the second arm of the restriction body 20 to increase the elastic pressing action force applied by the first and second arms 21, 22 of the restriction body to the conductive wire 80. The finger sections 43, 44 also serve to control the expansion range of the first and second arms 21, 22 in response to the plug-in of the conductive wire 80 so as to prevent the restriction body 20 from permanently deforming.

(33) Please refer to FIGS. 2 and 3. When the conductive wire 80 is plugged into the wire plug-in hole 92 (along the Z-direction reference axis) to contact the conductive component, the tail end 35 of the second section 32 of the metal leaf spring (in cooperation with the ridge section 13 of the main body 10) presses the conductive wire 80 against the main body 10. The rear end 81 of the conductive wire 80 goes through the wing sections 21a, 22a into the mouth section 26 of the restriction body 20, whereby the conductive wire 80 is elastically securely held by the first and second arms 21, 22 in cooperation with the aid unit 40. This improves the shortcoming of the conventional electrical connection terminal that due to external force, the conductive wire is apt to deflect or swing to lead to unstable contact and affect the electro-conduction efficiency and security. Moreover, the first and second arms 21, 22 in cooperation with the aid unit 40 press the conductive wire 80 (or the rear end 81 of the conductive wire 80) toward the main body 10 or the center of the restriction body 20 (or the mouth section 26) to increase the electro-conductive contact area and the electro-conduction efficiency.

(34) It should be noted that when a relatively large-diameter conductive wire is plugged into the conductive component and/or the wire trimming operation is performed, the rear end 81 of the conductive wire may be warped up. At this time, the rear end 81 of the conductive wire will be pressed/restricted or detained in the mouth section 26 by the first and second arms 21, 22 (and the aid unit 40) to keep in contact with the conductive component. This obviously improves the shortcoming of the conventional electrical connection terminal that the rear end of the conductive wire is apt to warp up and leave the conductive component so that the contact area between the conductive wire and the conductive component is reduced and the impedance is increased to raise the temperature of the conductive component.

(35) FIG. 4 shows a modified embodiment of the present invention, in which the restriction body 20 and the main body 10 are two pieces of components. The first and second arms 21, 22 of the restriction body are respectively bent from two ends of the base section 25 to gradually obliquely extend toward each other along the X-direction reference axis (or in a direction normal to the plug-in direction of the conductive wire 80). The first and second arms 21, 22 define the mouth section 26. A bent section 27, 28 is formed between each of the first and second arms 21, 22 and the free sections 23, 24, whereby the free section 23 of the first arm 21 and the free section 24 of the second arm 22 are bent to extend away from each other so as to define an opening 29.

(36) Please refer to FIGS. 5,6 and 7. The case 90 is formed with a recessed section 97 in communication with the chamber 91 for locating or receiving an elastic unit 50 and/or the base section 25 of the restriction body 20. The restriction body 20 is integrally formed and connected with the second section 12 of the main body. The base section 25 of the restriction body 20 is connected with the main body 10 (or the second section 12) or the second section 12 is formed with a neck section 15.

(37) As shown in the drawings, the first and second arms 21, 22 of the restriction body are respectively bent from the base section 25 to gradually obliquely extend toward each other along the Z-direction reference axis (or in the plug-in direction of the conductive wire 80). The first and second arms 21, 22 define the mouth section 26.

(38) A bent section 27, 28 is formed between each of the first and second arms 21, 22 and the free sections 23, 24, whereby the free section 23 of the first arm 21 and the free section 24 of the second arm 22 are bent to extend away from each other so as to define an opening 29 along the Z-direction reference axis (or in the plug-in direction of the conductive wire 80).

(39) In this embodiment, the elastic unit 50 serves to help in increasing the elastic holding/securing action force applied by the restriction body 20 to the conductive wire 80. The elastic unit 50 is selectively made of an electro-conductive material identical to the restriction body 20 or a material with rigidity (or elastic action force) greater than that of the restriction body 20, such as steel material or the like material.

(40) As shown in FIGS. 5, 6 and 7, the elastic unit 50 has a base 55 received in the recessed section 97 of the case, a first arm 51 and a second arm 52 (passing through the neck section 15 of the main body and extending along the Z-direction reference axis) connected with the base 55 and free sections 53, 54 connected with the first and second arms 51, 52.

(41) As shown in the drawings, the first and second arms 51, 52 of the elastic unit are respectively bent from two ends of the base 55 to gradually obliquely extend toward each other along the Z-direction reference axis (or in the plug-in direction of the conductive wire 80). The first and second arms 51, 52 define a mouth section 56 with a triangular configuration. A bent section 57, 58 is formed between each of the first and second arms 51, 52 and the free sections 53, 54 of the elastic unit, whereby the free section 53 of the first arm 51 and the free section 54 of the second arm 52 of the elastic unit are bent to extend away from each other so as to define an opening 59 along the Z-direction reference axis (or in the plug-in direction of the conductive wire 80). Accordingly, the elastic unit encloses or overlaps a part of the restriction body 20 or the entire restriction body 20.

(42) Please refer to FIGS. 6 and 7. When the conductive wire 80 is plugged through the wire plug-in hole 92 into the chamber 91 of the case and the conductive component, the rear end 81 of the conductive wire 80 is securely held by the bent section 27 of the first arm and the bent section 28 of the second arm in cooperation with the elastic unit 50. Therefore, even if the rear end 81 of the conductive wire is warped up, the rear end 81 of the conductive wire will still keep in contact with the first section 11 of the main body and the first and second arms 21, 22 of the restriction body.

(43) FIG. 8 shows a modified embodiment of the present invention, in which the restriction body 20 and the main body 10 are two pieces of components. The base section 25 of the restriction body 20 is assembled with the main body 10 (or the second section 12). The first and second arms 21, 22 of the restriction body 20 are respectively bent from two ends of the base section 25 to pass through the neck section 15 of the main body and gradually obliquely extend toward each other along the Z-direction reference axis (or in the plug-in direction of the conductive wire 80) to define the mouth section 26. A bent section 27, 28 is formed between each of the first and second arms 21, 22 and the free sections 23, 24 of the restriction body, whereby the free section 23 of the first arm 21 and the free section 24 of the second arm 22 are bent to extend away from each other so as to define an opening 29.

(44) Please refer to FIGS. 9, 10 and 11. The lower section of the case 90 is formed with an insertion cavity 98 in communication with the chamber 91 for helping in locating the aid unit 40 (or the base 45 of the aid unit). The lateral sides of the first section 12 of the main body are formed with notches 16 for assembling with the aid unit 40 (or the first and second waist sections 41, 42 of the aid unit). Accordingly, the first and second waist sections 41, 42 of the aid unit can extend along the X-direction reference axis (or toward the upper side of the case 90 in a direction normal to the conductive wire 80), whereby the finger sections 43, 44 can press/connect or latch with the restriction body 20.

(45) As shown in the drawings, the restriction body 20 is formed with insertion sections 27a, 28a, with which the finger sections 43, 44 of the aid unit 40 are inserted. In a preferred embodiment, the insertion sections 27a, 28a are groove or dent structures positioned on the bent sections 27, 28 and/or the first and second arms 21, 22 and the free sections 23, 24 of the restriction body 20.

(46) It should be noted that the inner sides of the first and second arms 21, 22 are formed with raised structures corresponding to the insertion sections 27a, 28a. Therefore, as shown in FIG. 10, the insertion sections 27a, 28a serve to prevent the rear end 81 of the conductive wire from moving upward or warping up. In addition, the aid unit 40 helps in increasing the elastic pressing action force applied by the restriction body 20 to the conductive wire 80 as shown in FIG. 11.

(47) FIG. 12 shows a modified embodiment of the present invention, in which the restriction body 20 and the main body 10 are two pieces of components. The base section 25 of the restriction body 20 is assembled with the main body 10 (or the second section 12). The first and second arms 21, 22 are respectively bent from two ends of the base section 25 to pass through the neck section 15 of the main body and gradually obliquely extend toward each other along the Z-direction reference axis (or in the plug-in direction of the conductive wire 80) to define the mouth section 26. A bent section 27, 28 is formed between each of the first and second arms 21, 22 and the free sections 23, 24 of the restriction body, whereby the free section 23 of the first arm 21 and the free section 24 of the second arm 22 are bent to extend away from each other so as to define an opening 29.

(48) Please refer to FIGS. 13, 14 and 15. The other end of the case 90 opposite to the wire plug-in hole 92 is formed with a locating slot 90a in communication with the chamber 91. The locating slot 90a extends along the Z-direction reference axis (or in the plug-in direction of the conductive wire 80) for assembling with or securing the main body 10 (the first section 11).

(49) As shown in the drawings, at least the first arm 21 (and/or the second arm 22) of the restriction body 20 is integrally connected with the first section 11 of the main body along the Z-direction reference axis (or in the plug-in direction of the conductive wire 80). In addition, the first arm 21 (and/or the second arm 22) of the restriction body 20 is bent along the Y-direction reference axis to form a base section 25 connected with the first and second arms 21, 22 to together define the mouth section 26 with the opening 29. A bent section 28 is formed between the second arm 22 (and/or the first arm 21) and the free section 24 (and/or the free section 23). The free section 24 of the second arm 22 (and/or the free section 23 of the first arm 21) is bent to extend toward the outer side of the restriction body 20, whereby the opening 29 is open along the Z-direction reference axis (or in the plug-in direction of the conductive wire 80).

(50) In this embodiment, the elastic unit 50 assembled with the restriction body 20 is similar to or identical to the restriction body 20. At least the first arm 51 (and/or the second arm 52) of the elastic unit 50 extends along the Z-direction reference axis (or in the plug-in direction of the conductive wire 80). In addition, the first arm 21 (and/or the second arm 22) of the elastic unit 50 is bent along the Y-direction reference axis to form a base section 55 connected with the first and second arms 51, 52 to together define the mouth section 56 with the opening 59.

(51) As shown in the drawings, a bent section 58 is formed between the second arm 52 (and/or the first arm 51) and the free section 54 (and/or the free section 53). The free section 54 of the second arm 52 (and/or the free section 53 of the first arm 51) is bent to extend toward the outer side of the elastic unit 50, whereby the opening 59 is open along the Z-direction reference axis (or in the plug-in direction of the conductive wire 80). Accordingly, the elastic unit 50 encloses or overlaps a part of the restriction body 20 or the entire restriction body 20 as shown in FIGS. 14 and 15.

(52) Please refer to FIGS. 14 and 15. After the conductive wire 80 is plugged through the wire plug-in hole 92 into the chamber 91 of the case and the conductive component, the rear end 81 of the conductive wire 80 is securely held by the bent section 28 of the second arm of the restriction body in cooperation with the first arm 21 and the elastic unit 50. Therefore, the rear end 81 of the conductive wire is detained in the mouth section 26 of the restriction body, whereby the conductive wire will at least keep in contact with the first section 11 of the main body and the restriction body 20 (or the first arm 21.

(53) Please refer to FIGS. 16, 17 and 18. The restriction body 20 and the main body 10 are two pieces of components. The main body 10 (the first section 11) is bent along the X-direction reference axis to form a connection section 17. The connection section 17 is assembled and connected with the restriction body 20 (the first arm 21 and/or the second arm 22) by means of adhesion, riveting, welding, locking, etc.

(54) Please refer to FIGS. 17 and 18. After the conductive wire 80 is plugged through the wire plug-in hole 92 into the chamber 91 of the case and the conductive component, the rear end 81 of the conductive wire 80 is securely held by the bent section 28 of the second arm of the restriction body in cooperation with the first arm 21 and the elastic unit 50. Therefore, the rear end 81 of the conductive wire is detained in the mouth section 26 of the restriction body, whereby the conductive wire will at least keep in contact with the first section 11 of the main body, the restriction body 20 (or the bent section 28 of the second arm) and the connection section 17 of the main body.

(55) Please refer to FIGS. 19 and 20, which show a modified embodiment of the present invention. In this embodiment, the restriction body 20 is integrally formed on the main body 10 and assembled with an -shaped metal leaf spring 30.

(56) In this embodiment, the metal leaf spring 30 is an -shaped structure including a first section 31, a second section 32 and a bow section 33 connected between the first and second sections 31, 32. The first section 31 has a head end 34. The second section 32 is formed with a window 39 and a tail end 35 close to or adjacent to the second section 32. The head end 34 can be pressed and connected on the main body 10 (or the first section 11). The first section 31 and the bow section 33 provide elastic effect, whereby the main body 10 (or the first section 11) can block the window 39.

(57) When an operator presses the metal leaf spring 30, the window 39 is unblocked, permitting the conductive wire 80 to enter the main body 10 through the window 39 to be securely held by the restriction body 20 assembled with the elastic unit 50. After the external pressing force applied to the metal leaf spring 30 disappears, the second section 32 and/or the window 39 is restored to securely press/restrict the conductive wire 80 together with the first section 11 of the main body (and/or the ridge section 13) as shown in FIG. 20.

(58) Please refer to FIGS. 21 and 22, which show a preferred embodiment of the present invention, in which the restriction body 20 and the main body 10 are two pieces of components. The restriction body 20 and the main body 10 are assembled with each other and applied to an -shaped metal leaf spring 30.

(59) In this embodiment, the main body 10 (or the first section 11) is bent along the X-direction reference axis to form a connection section 17. The connection section 17 is assembled and connected with the restriction body 20 (the first arm 21 and/or the second arm 22) by means of adhesion, riveting, welding, locking, etc. The restriction body 20 is assembled with the elastic unit 50 and cooperates with the window 39 of the -shaped metal leaf spring 30 and the first section 11 of the main body (and/or the ridge section 13 of the first section 11) to together securely hold the conductive wire 80.

(60) It should be noted that the V-shaped metal leaf spring or -shaped metal leaf spring 30 can be alternatively assembled with and applied to the restriction body 20, the aid unit 40 or elastic unit 50 of the conductive component in accordance with practical requirement.

(61) To speak representatively, in comparison with the conventional wire connection terminal, the conductive component structure of electrical wire connection device of the present invention has the following advantages: 1. The main body 10, the restriction body 20, the metal leaf spring 30, the aid unit 40 and the elastic unit 50 of the conductive component and the relevant components and structures have been redesigned. For example, the first section 11 or the second section 12 of the main body 10 is assembled with the restriction body 20. The restriction body 20 (and/or the elastic unit 50) has a first arm 21 (and/or 51), a second arm 22 (and/or 52), free sections 23, 24 (and/or 53, 54) and bent sections 27, 28 (and/or 57, 58). The restriction body 20 (and/or the elastic unit 50) is formed with a mouth section 26 (and/or 56) and opening 29 (and/or 59). The restriction body 20 is formed with the wing sections 21a, 22a. The restriction body 20 is assembled with the aid unit 40 or the elastic unit 50. The aid unit 40 includes a first waist section 41, a second waist section 42, a base 45 and finger sections 43, 44. The present invention is obviously different from the conventional wire connection terminal in use and operation form. Also, the present invention changes the electro-conductive structure and assembling relationship of the conventional electrical connection terminal or switch wire connection device. 2. In condition that the thickness of the conductive component and/or the metal leaf spring 30 is not increased, the cooperative structures of the conductive component or the restriction body provides a more idealistic system and greater elastic deformation amount for pressing/restricting the conductive wire 80 than the conventional electrical connection terminal. The conductive component keeps in multi-section contact with the conductive wire 80. Therefore, the conductive component is applicable to some electrical connection terminals or switch wire connection devices, permitting a large-diameter conductive wire to connect therewith. In addition, the present invention improves the shortcomings of the conventional structure that the pressing force applied to the conductive wire is insufficient and the conductive wire can be hardly securely pressed and restricted so that the conductive wire is apt to deflect or swing (due to incautious touch of an operator) to lead to poor contact and insecurity. 3. Especially, the main body 10 is assembled with the restriction body 20 and the aid unit 40 or the elastic unit 50 to provide a conductive component structure capable of helping the metal leaf spring to press and restrict the conductive wire 80. In addition, the aid unit 40 and the elastic unit 50 are replaceably assembled with the restriction body 20. The present invention obviously improves the shortcoming of the conventional structure that when the metal leaf spring presses the conductive wire, a leverage effect is often produced to cause the rear end of the conductive wire to warp up (or leave the conductive component) so that the electro-conductive contact area is reduced to affect the electro-conduction efficiency.

(62) In conclusion, the conductive component structure of electrical wire connection device of the present invention is different from the conventional wire connection terminal in space form and is advantageous over the conventional wire connection terminal. The conductive component structure of electrical wire connection device of the present invention is effective, greatly advanced and inventive.

(63) The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
