The load arm 16 passes through the first elastic section 21 and at least a part of the second elastic section 22. When the load arm 16 is (displaced) moved, in response to the (displacement) motion of the load arm 16, the first and second elastic sections 21, 22 (at the same time) respectively provide tension (or pushback force) and pulling force effect. This enhances the secure connection force of the conductive component 10 fastened on the grounding rail. Also, elastic fatigue of the elastic unit 20 is not easy to take place so as to improve the shortcoming of the conventional conductive component that in the case of long-term (or highly frequent) use, elastic (or material) fatigue of one single elastic member is easy to take place to affect the securing effect.

    [0040] To speak more specifically, the first section 11 and/or the second section 12 define a space 30. In an area in adjacency to the space 30, on the upper and lower sides of the load arm 16 are respectively disposed an upper arm 17, a shoulder section 17a connected with the upper arm 17, a lower arm 18 and a shoulder section 18a connected with the lower arm 18 on the first section 11 and/or the second section 12. In addition, an assembling section 19 in the form of perforation structure is disposed between the space 30 and the base section 10a.

    [0041] In this embodiment, the upper arm 17 and the lower arm 18 are respectively formed with raised sections 17b, 18b. The shoulder section 17a of the upper arm 17 cooperates with the raised section 17b of the upper arm 17 and the shoulder section 18a of the lower arm 18 cooperates with the raised section 18b of the lower arm 18 to help in mounting the elastic unit 20.

    [0042] It should be noted that the raised section 17b and/or the raised section 18b also serve as restriction systems for restraining the motional range or displacement of the first elastic section 21 and/or the second elastic section 22 to lower the possibility of deformation or elastic (or material) fatigue of the first portion 14 and second portion 15 and/or the first elastic section 21 and second elastic section 22 due to improper operation of an operation or long-term (or highly frequent) use.

    [0043] As shown in FIGS. 2 and 3, the load arm 16 is a T-shaped structure having a subsidiary section 16a. One end of the load arm 16 is connected with the first portion 14 (and/or the second portion 15). The other end or at least a part (and the subsidiary section 16a) of the load arm 16 are positioned in the space 30.

    [0044] In this embodiment, the first elastic section 21 and the second elastic section 22 of the elastic unit 20 can be a two-piece structure or integrally connected with each other to form a substantially M-shaped structure. The first elastic section 21 and/or the second elastic section 22 of the elastic unit 20 alternatively can have the form of a coiled spring.

    [0045] As shown in the drawings, the first elastic section 21 and the second elastic section 22 respectively have main arms 21a, 22a and subsidiary arms 21b, 22b and (bow-shaped) bridge sections 21c, 22c connected between the main arms 21a, 22a and the subsidiary arms 21b, 22b. The subsidiary arm 21b of the first elastic section 21 is attached to or connected with the main arm 22a of the second elastic section 22.

    [0046] As shown in the drawings, the main arm 21a and the subsidiary arm 21b of the first elastic section 21 and the main arm 22a and the subsidiary arm 22b of the second elastic section 22 are respectively formed with arcuate sections 23 for enhancing the structural strength of the main arms 21a, 22a and the subsidiary arms 21b, 22b. In addition, the load arm 16 at least passes through the main arm 21a and the subsidiary arm 21b of the first elastic section 21 and the main arm 22a of the second elastic section 22, when the load arm 16 is (displaced) moved, in response to the (displacement) motion of the load arm 16, the first elastic section 21 is compressed, while the second elastic section 22 is tensioned.

    [0047] Moreover, when the load arm 16 (and/or the subsidiary section 16a) is restored or moved back, the first elastic section 21 releases the stored energy to provide tension (or pushback force), while the second elastic section 22 releases the stored energy to provide pulling force (or back pulling force). This helps in storing the first portion 14 and/or the second portion 15 to their initial states (or home positions without being forced).

    [0048] To speak more specifically, the main arm 21a and the subsidiary arm 21b of the first elastic section 21 and the main arm 22a and the subsidiary arm 22b of the second elastic section 22 are respectively formed with splits 24, which permit the load arm 16 to pass through and/or assembled with the load arm 16.

    [0049] Therefore, the main arm 21a of the first elastic section 21 is positioned between the shoulder sections 17a, 18a and the raised sections 17b, 18b, whereby the main arm 21a of the first elastic section 21 is leant against the shoulder sections 17a, 18a (or the main arm 21a of the first elastic section 21 is positioned between the first portion 14 (and/or the second portion 15) and the raised sections 17b, 18b, whereby the main arm 21a of the first elastic section 21 is leant against the first portion 14 (and/or the second portion 15). The subsidiary arm 21b of the first elastic section 21 and the main arm 22a of the second elastic section 22 are positioned between the raised sections 17b, 18b and the subsidiary section 16a, whereby the main arm 22a of the second elastic section 22 is leant against the subsidiary section 16a. The subsidiary arm 22b of the second elastic section 22 is positioned on the assembling section 19.

    [0050] In a preferred embodiment, the subsidiary arm 22b of the second elastic section 22 can be secured to the case body 50. Alternatively, the assembling section is disposed on the case body 50 for fixing the subsidiary arm 22b of the second elastic section 22. In addition, the case body 50 can be formed with a chamber 53 for (helping) receiving the elastic unit 20.

    [0051] As shown in FIGS. 2 and 3, a stop section 54 in the form of a rib body is disposed on the case body 50 for restricting the moving distance or displacement of the first portion 14 (and/or the second portion 15) or the load arm 16 of the conductive component so as to lower the possibility of elastic (or material) fatigue or breakage of the first portion 14 (or the second portion 15) due to improper operation of an operation or long-term (or highly frequent) use, which will sequentially affect the fastening and securing effect of the rail and the conduction effect of the conductive component.

    [0052] Please refer to FIG. 4. When an operator operates a tool 60 (such as a screwdriver) to pull a foot-like section 59 on a lower side of the case body 50 outward (or toward the left side of the drawing), the case body 50 will drive the first portion 14 of the conductive component to move toward the left side of the drawing. In cooperation with the first portion 14, which moves to the position of the stop section 54, some motions take place as follows: [0053] 1. The load arm 16 (and the subsidiary section 16a) drives the subsidiary arm 21b of the first elastic section 21 and the main arm 22a of the second elastic section 22 to move toward the left side of the drawing (as shown by the solid line of FIG. 4). At this time, the first elastic section 21 of the elastic unit 20 is compressed to store energy and provide a pressure resistant action force (or pushback force). [0054] 2. The load arm 16 (and the subsidiary section 16a) at the same time drives the main arm 22a of the second elastic section 22 to move toward the left side of the drawing, whereby with the assembling section 19 serving as a support point, the subsidiary arm 22b of the second elastic section 22 is tensioned to store energy and provide tensile action force (or back pulling force).

    [0055] That is, the operator can perform the above operation to unfasten the first portion (and/or the second portion 15) from the rail.

    [0056] When the operation force disappears, the first elastic section 21 of the elastic unit 20 will release the previously stored energy due to compression, whereby the subsidiary arm 21b of the first elastic section 21 pushes back the subsidiary section 16a of the load arm 16 to move toward the right side of the drawing. Also, the second elastic section 22 will release the previously stored energy due to tension, whereby the main arm 22a of the second elastic section 22 pulls back the subsidiary section 16a of the load arm 16 to move toward the right side of the drawing to together help in elastically storing the first portion 14 (and/or the second portion 15) to their initial positions as shown by the phantom line of FIG. 4.

    [0057] It should be noted that when an operator operates the conductive component 10 to fasten with the (grounding) rail, the first portion 14 (and/or the second portion 15) is slightly (expanded) tensioned. At the same time, the load arm 16 (or the subsidiary section 16a) is driven to make the first elastic section 21 of the elastic unit 20 provide a pressure resistant action force (or pushback force) and/or make the second elastic section 22 provide a tensile action force (or back pulling force), whereby the elastic unit 20 helps in enhancing the fastening force and security of the conductive component 10 (for fastening the conductive component on the rail).

    [0058] Please refer to FIG. 5, which shows the structure of a preferred embodiment of the elastic unit 20 of the present invention. The first elastic section 21 of the elastic unit 20 is a U-shaped structure. The split 24 extends along the main arm 21a of the first elastic section 21 (or the U-shaped structure) through the bridge section 21c to the subsidiary arm 21b. In addition, the tail end of the main arm 21a and the tail end of the subsidiary arm 21b are respectively formed with closed section 25. Therefore, when the load arm 16 is assembled with the split 24 of the first elastic section 21, the closed sections 25 help in securely assembling the split 24 of the first elastic section 21 with the load arm 16.

    [0059] FIG. 5 also shows that the arcuate sections 23 of the main arm 21a and the subsidiary arm 21b of the first elastic section 21 are arced structures bent toward each other, while the arcuate sections 23 of the main arm 22a and the subsidiary arm 22b of the second elastic section 22 are arced structures bent away from each other. Accordingly, the arcuate section 23 of the main arm 22a of the second elastic section 22 is overlapped with or attached to the arcuate section 23 of the subsidiary arm 21b of the first elastic section 21.

    [0060] Please refer to FIG. 6, which shows the structure of a modified embodiment of the elastic unit 20 of the present invention. The arcuate sections 23 of the main arm 21a and the subsidiary arm 21b of the first elastic section 21 are arced structures bent toward each other and the arcuate sections 23 of the main arm 22a and the subsidiary arm 22b of the second elastic section 22 are arced structures also bent toward each other. Accordingly, the arcuate section 23 of the main arm 22a of the second elastic section 22 and the arcuate section 23 of the subsidiary arm 21b of the first elastic section 21 together define a void section 26.

    [0061] Please refer to FIGS. 7, 8 and 9, which show the structure of a modified embodiment of the elastic unit 20 in adaptation to the case body 50 of the present invention. The elastic unit 20 has a (bow-shaped) subsidiary bridge section 27 formed between the subsidiary arm 21b of the first elastic unit 21 and the main arm 22a of the second elastic section 22, whereby the elastic unit 20 substantially has the form of an M-shaped structure or the elastic unit 20 substantially has the form of a waved structure (or has a system of third elastic section). This enhances the pressure resistant effect (or pushback force) of the elastic unit 20 (or the first elastic section 21) and the tensile effect (or back pulling force) of the second elastic section 22.

    [0062] In this embodiment, the subsidiary bridge section 27 is also formed with a split 24 connected with the split 24 of the subsidiary arm 21b of the first elastic section 21 and the split 24 of the main arm 22a of the second elastic section 22. As shown in the drawings, the load arm 16 at least passes through the main arm 21a and the subsidiary arm 21b of the first elastic section 21 and the subsidiary bridge section 27 and the main arm 22a of the second elastic section 22. Therefore, when the load arm 16 is (displaced) moved, in response to the (displacement) motion of the load arm 16, the first elastic section 21 (and/or the subsidiary bridge section 27) is compressed, while the second elastic section 22 is tensioned.

    [0063] When the load arm 16 (and/or the subsidiary section 16a) is restored or moved back, the first elastic section 21 (and/or the subsidiary bridge section 27) releases the stored energy to provide tension (or pushback force), while the second elastic section 22 releases the stored energy to provide pulling force (or back pulling force). This helps in storing the first portion 14 and/or the second portion 15 to their initial states (or home positions without being forced).

    [0064] To speak more specifically, the main arm 21a of the first elastic section 21 is positioned between the shoulder sections 17a, 18a and the raised sections 17a, 18b, whereby the main arm 21a of the first elastic section 21 is leant against the shoulder sections 17a, 18a (or the main arm 21a of the first elastic section 21 is positioned between the first portion 14 (and/or the second portion 15) and the raised sections 17b, 18b, whereby the main arm 21a of the first elastic section 21 is leant against the first portion 14 (and/or the second portion 15). The subsidiary arm 21b of the first elastic section 21, the subsidiary bridge section 27 and the main arm 22a of the second elastic section 22 are positioned between the raised sections 17b, 18b and the subsidiary section 16a, whereby the main arm 22a of the second elastic section 22 is leant against the subsidiary section 16a. The subsidiary arm 22b of the second elastic section 22 is positioned on the assembling section 19 (or the subsidiary arm 22b of the second elastic section 22 is secured to the case body 50 (or the assembling section of the case body 50)).

    [0065] Please refer to FIG. 10. When an operator operates a tool 60 (such as a screwdriver) to pull the foot-like section 59 on the lower side of the case body 50 outward (or toward the left side of the drawing), the case body 50 will drive the first portion 14 of the conductive component to move toward the left side of the drawing. In cooperation with the first portion 14, which moves to the position of the stop section 54, some motions take place as follows: [0066] 1. The load arm 16 (and the subsidiary section 16a) drives the subsidiary arm 21b of the first elastic section 21 and the main arm 22a of the second elastic section 22 to move toward the left side of the drawing (as shown by the solid line of FIG. 10). At this time, the first elastic section 21 (and/or the subsidiary bridge section 27) of the elastic unit 20 is compressed to store energy and provide a pressure resistant action force (or pushback force). [0067] 2. The load arm 16 (and the subsidiary section 16a) at the same time drives the main arm 22a of the second elastic section 22 to move toward the left side of the drawing, whereby with the assembling section 19 serving as a support point, the subsidiary arm 22b of the second elastic section 22 is tensioned to store energy and provide tensile action force (or back pulling force).

    [0068] When the operation force disappears, the first elastic section 21 of the elastic unit 20 (and/or the subsidiary bridge section 27) will release the previously stored energy due to compression, whereby the subsidiary arm 21b of the first elastic section 21 (and/or the subsidiary bridge section 27) pushes back the subsidiary section 16a of the load arm 16 to move toward the right side of the drawing. Also, the second elastic section 22 will release the previously stored energy due to tension, whereby the main arm 22a of the second elastic section 22 pulls back the subsidiary section 16a of the load arm 16 to move toward the right side of the drawing to together help in elastically storing the first portion 14 (and/or the second portion 15) to their initial positions as shown by the phantom line of FIG. 10.

    [0069] Please refer to FIG. 11, which shows the structure of a modified embodiment of the elastic unit 20. The subsidiary arm 22b (and/or the subsidiary arm 21b) of the second elastic section 22 (and/or the first elastic section 21) is connected with a (bow-shaped) subsidiary bridge section 27. The subsidiary bridge section 27 is connected with an extension arm 27a. The extension arm 27a is connected with a (bow-shaped) secondary bridge section 27c. The secondary bridge section 27c is connected with a secondary arm 27b, whereby the second elastic section 22 (and/or the first elastic section 21) substantially has the form of an M-shaped structure or the elastic unit 20 substantially has the form of a waved structure to form a system of a third elastic section and a fourth elastic section).

    [0070] As shown in the drawing, at least a part of the subsidiary arm 22b of the second elastic section 22, the subsidiary bridge section 27, the extension arm 27a and the secondary arm 27b are formed with a split 24.

    [0071] Please refer to FIGS. 12 and 13, which show the structures of the conductive component 10 and the elastic unit 20. The load arm 16 (or the subsidiary section 16a) is connected with a tail section 16b extending from the subsidiary section 16a and positioned in the space 30.

    [0072] Please refer to FIGS. 13 and 14. The main arm 21a and the subsidiary arm 21b of the first elastic section 21 and the main arm 22a of the second elastic section 22 are positioned between the shoulder sections 17a, 18a and the subsidiary section 16a, whereby the main arm 21a of the first elastic section 21 is leant against the shoulder sections 17a, 18a (or the main arm 21a of the first elastic section 21 is leant against the first portion 14 (and/or the second portion 15)) and the main arm 22a of the second elastic section 22 is leant against the subsidiary section 16a. Also, the tail section 16b of the load arm 16 is positioned in the split 24 of the subsidiary bridge section 27 of the second elastic section 22 and the secondary arm 27b is positioned on the assembling section 19 (or the secondary arm 27b is secured to the case body 50 (or the assembling section of the case body 50)).

    [0073] Accordingly, the load arm 16 at least passes through the main arm 21a and the subsidiary arm 21b of the first elastic section 21 and the main arm 22a of the second elastic section 22. Therefore, when the load arm 16 is (displaced) moved, in response to the (displacement) motion of the load arm 16, the first elastic section 21 is compressed, while the second elastic section 22 (and/or the subsidiary bridge section 27, the extension arm 27a, the secondary bridge section 27c and the secondary arm 27b) is tensioned.

    [0074] When the load arm 16 (and/or the subsidiary section 16a and the tail section 16b) is restored or moved back, the first elastic section 21 releases the stored energy to provide tension (or pushback force), while the second elastic section 22 (and/or the subsidiary bridge section 27 and the secondary bridge section 27c) releases the stored energy to provide pulling force (or back pulling force). This helps in storing the first portion 14 and/or the second portion 15 to their initial states (or home positions without being forced).

    [0075] It should be noted that in the condition that the manufacturing cost is not taken into consideration, the first elastic section 21 and the second elastic section 22 of the elastic unit 20 respectively provide pressure resistant action force and tensile action force. According to such system, the structures of the first elastic section 21 and the second elastic section 22 can be alternatively selectively made of different metal material (property). For example, the first elastic section 21 can be selectively made of a high-performance material with higher resistance against pressure (yield point) and the second elastic section 22 can be selectively made of a high-performance material with higher tensile strength (yield point).

    [0076] To speak representatively, in comparison with the conventional terminal device, the conductive component structure of the rail-type terminal device of the present invention has the following advantages: [0077] 1. The conductive component 10 (and/or the elastic unit 20) and the relevant component structures have been redesigned. For example, the conductive component 10 includes a base section 10a, a first section 11, a second section 12, a first portion 14, a second portion 15 and an assembling section 19. The first section 11 and/or the second section 12 define a space 30 and are formed with an upper arm 17 and a lower arm 18 (and/or shoulder sections 17a, 18a and raised sections 17b, 18b). A load arm 16 and a subsidiary section 16a (and/or a tail section 16b) and the elastic unit 20 are received in the space 30. The elastic unit 20 includes a first elastic section 21, a second elastic section 22, main arms 21a, 22a, subsidiary arms 21b, 22b, bridge sections 21c, 22c, arcuate section 23 and a split 24 (and/or extension arm 27a, secondary bridge section 27c and secondary arm 27b) assembled with the load arm 16 to help in enhancing the elasticity (elastic force) of the first portion 14 and/or the second portion 15. The present invention is obviously different from the conventional terminal device in use and operation form. Also, the present invention changes the electro-conductive structure or assembling relationship of the conventional terminal device. [0078] 2. Especially, the load arm 16 of the conductive component 10 is assembled with the elastic unit 20. By means of the cooperative structures, when the conductive component 10 is (displaced) moved due to operation of an operator, the first and second elastic sections 21, 22 at the same time respectively have or provide two force systems of pressure resistant effect and tensile effect. This obviously prolongs the lifetime and effect of the elastic unit 20. Also, this improves the shortcoming of the conventional terminal device that in case single elastic action force is lost, the assistance of the elastic member in securely fastening the grounding member on the rail is deteriorated or reduced or it is necessary to selectively use special metal material (such as the high-performance material with higher resistance against pressure (yield point)) or simply increase the number of the elastic units so as to prolong the lifetime of the elastic unit. Relatively, a more stable and optimal elastic securing system is set up. Accordingly, in the case of improper operation and/or long-term (or highly frequent) use, the fastening and securing effect of the conductive component 10 to the rail in successive use will not be deteriorated so that the conductive effect of the conductive component 10 can be ensured.

    [0079] In conclusion, the conductive component structure of the rail-type terminal device of the present invention is effective and different from the conventional terminal device in space form and is advantageous over the conventional terminal device. The conductive component structure of the rail-type terminal device of the present invention is greatly advanced and inventive.

    [0080] 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.
