DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] Please refer to FIGS. 4, 5 and 6. The wire connection terminal device of the present invention includes a main body 40 made of insulation material and a pressing/moving unit 60 assembled with the main body 40. The main body 40 defines a chamber 41. A metal leaf spring 70 and a terminal pin component 80 are mounted in the chamber 41. The terminal pin component 80 is plugged on a circuit board (such as a PCB, not shown). The main body 40 includes a wire inlet 42 in communication with the chamber 41 and a recessed section 42a formed on the wire inlet 42. The recessed section 42a serves to help in guiding a conductive wire 50 to plug through the wire inlet 42 into the chamber 41. After plugged into the chamber 41, the conductive wire 50 is pressed by the metal leaf spring 70 and electrically connected with the terminal pin component 80.

[0030] The upper section, upper side, lower section, lower side or bottom section mentioned hereinafter are referred to with the direction of the drawings as the reference direction.

[0031] In this embodiment, the metal leaf spring 70 is responsive to the motion of the pressing/moving unit 60 to release the conductive wire 50. To speak more specifically, the pressing/moving unit 60 has a shafted section 61, a cam section 62 connected with the shafted section 61 and a force application section 63 formed on the cam section 62 and a press section 64 formed on the cam section 62.

[0032] As shown in the drawings, the shafted section 61 is formed with a shaft hole 65 pivotally connected on a shaft post 43 of the main body 40 (or the chamber 41). Accordingly, the cam section 62 can freely rotate or swing within the chamber 41 of the main body 40. The force application section 63 protrudes from an upper section of the cam section 62 to form two stepped structures. In addition, the force application section 63 and the cam section 62 together define a cavity 66. A base board 67 is formed on one side of the cam section 62 (or one of the stepped structures). One end of the base board 67 protrudes from the base board 67 to form the press section 64.

[0033] In this embodiment, as shown in the drawings, the upper section of the main body 40 is formed with a socket 44 and an insertion section 45 for detachably assembling with a cover 55. Corresponding to the socket 44 and the insertion section 45, the cover 55 is formed with an insertion block 56, an insertion portion 57 and a shoulder section 58 formed at a rear end of the insertion portion 57. Accordingly, when the insertion block 56 and the shoulder section 58 are respectively mounted into the socket 44 and the insertion section 45 of the main body 40, the insertion portion 57 of the cover 55 is received in the cavity 66 of the pressing/moving unit 60.

[0034] In a preferred embodiment, the main body 40 is formed with a stopper section 48 in adjacency to the shaft post 43. The stopper section 48 is a block body structure, which can cooperate with the base board 67 to hinder the pressing/moving unit 60 from being over-rotated. For example, the base board 67 can be formed with a protrusion section or a slot rail structure 67a assembled with the stopper section 48. When operating the pressing/moving unit 60 to swing, the slot rail structure 67a can cooperate with the stopper section 48 to restrict the rotation or swing of the pressing/moving unit 60 within a certain range.

[0035] The mechanism for restricting the rotation or swing of the pressing/moving unit 60 within a certain range can also include a stop section 49 formed on the main body 40 in the form of a block body structure. Therefore, when the base board 67 of the pressing/moving unit 60 is rotated or swung to a position where the stop section 49 is positioned, the stop section 49 will stop the base board 67 to prevent the pressing/moving unit 60 from being over-rotated or over-swung.

[0036] As shown in the drawings, the lower end section of the base board 67 is formed with a restriction section 68. The restriction section 68 has an extension face 68a in the form of a slope structure for guiding the conductive wire 50 to enter the terminal pin component 80. That is, when the conductive wire 50 passes through the extension face 68a, the slope structure of the extension face 68a will guide the conductive wire 50 into the terminal pin component 80. A notch 69 is formed between the restriction section 68 and the press section 64. The restriction section 68 also serves to help in restricting the rotation or swing of the pressing/moving unit 60 within a certain range. This will be further described hereinafter.

[0037] Please further refer to FIGS. 4, 5 and 6. The metal leaf spring 70 is a substantially U-shaped structure. The metal leaf spring 70 has a first section 71, a second section 72 and a bight section 73 connected between the first and second sections 71, 72. The first section 71 includes ahead end 74 and the second section 72 includes a tail end 75. The metal leaf spring 70 is mounted on a stake 46 of the main body 40, whereby the first section 71 and/or the head end 74 can move or swing within the chamber 41. As shown in the drawings, the pressing/moving unit 60 and the metal leaf spring 70 are respectively disposed on two sides of the chamber 41 of the main body 40.

[0038] Please now refer to FIGS. 5, 6 and 7. The terminal pin component 80 is mounted in the chamber 41 of the main body 40. The terminal pin component 80 is a board body structure with a geometrical configuration. The terminal pin component 80 includes a first side 81, which is bent and formed on lower side of the board body structure, a second side 82 positioned above the first side 81, a subsidiary side 83 connected with the first side 81 and terminal pins 84 bent and protruding from the first side 81. The second side 82 has the form of a slope inclined from the first side 81. The inclination angle of the second side 82 is equal to the angle by which the conductive wire 50 is plugged into the main body 40 or the wire inlet 42, whereby the second side 82 can more snugly contact the conductive wire 50. In addition, the second side 82 has a tip 85 for helping the head end 74 of the metal leaf spring 70 to together bite the conductive wire 50 and truly secure the conductive wire 50.

[0039] As shown in the drawings, the first side 81 of the terminal pin component 80 is positioned on the bottom section 47 of the main body 40 with the terminal pins 84 extending out of the main body 40. In addition, the second section 72 and the tail end 75 of the metal leaf spring 70 respectively contact the first side 81 and the subsidiary side 83 of the terminal pin component 80. The head end 74 of the metal leaf spring 70 contacts the second side 82 of the terminal pin component 80.

[0040] Please now refer to FIG. 8. The above structurally cooperative form permits an operator to directly plug the conductive wire 50 through the wire inlet 42 into the chamber 41. Due to the elasticity of the metal leaf spring 70 and/or the head end 74, the conductive wire 50 can move along the second side 82 of the terminal pin component 80 to be pressed or bitten by the head end 74 of the metal leaf spring 70 and electrically connected with the terminal pin component 80 and the metal leaf spring 70.

[0041] Please refer to FIG. 9. When the operator presses down the force application section 63 of the pressing/moving unit 60 (in the direction of the arrow), the press section 64 is driven to press down the head end 74 of the metal leaf spring 70 so as to release the conductive wire 50 from the pressing or biting of the head end 74. At this time, the operator can extract the conductive wire 50 out of the main body 40.

[0042] As shown in the drawings, the restriction section 68 of the pressing/moving unit 60 contacts the tail end 75 of the metal leaf spring 70 or the base board 67 is stopped by the stop section 49 of the main body 40. That is, the rotation range or swing range of the pressing/moving unit 60 is set to the position where the restriction section 68 reaches the tail end 75 of the metal leaf spring 70 or the first side 81 (or the subsidiary side 83) of the terminal pin component 80, or the rotation range or swing range of the pressing/moving unit 60 is set to the position where the base board 67 reaches the stop section 49. In this case, the pressing/moving unit 60 will not be over-rotated or swung.

[0043] It should be noted that in case the position where the shaft hole 65 of the pressing/moving unit 60 is pivotally connected with the shaft post 43 as a fulcrum is defined as a rotational center or swinging center C, the length L1 between the force application section 63 (or the force application point) and the swinging center C (or the shaft hole 65 and the shaft post 43) is smaller than the length L2 between the press section 64 and the swinging center C (or the shaft hole 65 and the shaft post 43). Accordingly, the (depressing) displacement S1 of the force application section 63 is smaller than the (depressing) displacement S2 of the press section 64. That is, in comparison with the conventional terminal device, the motional travel of the pressing/moving unit 60 or the force application section 63 is as minimized as possible. The operator only needs to operate the force application section 63 to move by a smaller amount or travel so as to release the conductive wire 50 from the pressing of the head end 74 of the metal leaf spring 70 and electrically disconnect the conductive wire 50 from the metal leaf spring 70.

[0044] It should be noted that the (depressing) operational direction of the force application section 63 or the press section 64 is as identical to the (longitudinal) motional direction of the metal leaf spring 70 as possible. This is beneficial to directly press the head end 74 of the metal leaf spring 70. In this case, the shortcoming of the conventional structure that it is laborious to use a push member to laterally push/press the metal leaf spring.

[0045] To speak representatively, the wire connection terminal device of the present invention can be stably operated to truly press the conductive wire. In comparison with the conventional terminal device, the wire connection terminal device of the present invention has the following advantages: [0046] 1. The terminal device or the relevant connection components thereof have been redesigned in use, structural design and connection relationship. For example, the main body 40 is formed with the socket 44 and the insertion section 45 assembled with the insertion block 56, the insertion portion 57 and the shoulder section 58 of the cover 55. The pressing/moving unit 60 has a shafted section 61, whereby the cam section 62 can freely rotate or swing within the chamber 41 of the main body 40. The force application section 63 and the cam section 62 together define the cavity 66 for receiving therein the insertion portion 57. The base board 67 is formed on one side of the cam section 62 and one end of the base board 67 protrudes from the base board 67 to form the press section 64 and the restriction section 68. The terminal pin component 80 includes the first side 81, the subsidiary side 83 and the second side 82 in the form of a slope in cooperation with the metal leaf spring 70. The use form and application of the terminal device of the present invention are obviously changed and different from the conventional terminal device. [0047] 2. The length between the force application section 63 of the pressing/moving unit 60 and the shafted section 61 (or the swinging center C) is smaller than the length between the press section 64 and the shafted section 61 (or the swinging center C). Accordingly, the operational travel of the force application section 63 is obviously smaller than the operational travel of the conventional structure. The pressing/moving unit 60 and/or the force application section 63 can be as disposed in the main body 40 as possible without protruding from the main body 40 so as to minimize the possibility of mis-touch of an operator. Moreover, in the conventional terminal device, it is necessary to enlarge the volume of the case to provide sufficient operational travel or reserve operational space to affect the arrangement space of the working site and the environmental equipment. The terminal device of the present invention apparently improves the shortcomings of the conventional terminal device.

[0048] In conclusion, the wire connection terminal device of the present invention is effective and different from the conventional terminal device in space form. The wire connection terminal device of the present invention is inventive, greatly advanced and advantageous over the conventional terminal device.

[0049] 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.
