DETAILED DESCRIPTION

[0036] The technical contents of this disclosure will become apparent with the detailed description of embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.

[0037] Please refer to FIG. 1 to FIG. 4, which depict a perspective schematic view of the terminal block with a handle in this disclosure, a perspective exploded schematic view of the terminal block with a handle in this disclosure, a perspective schematic view of the handle in this disclosure and a cross-sectional schematic view of the terminal block with a handle in this disclosure. As shown in FIG. 1, this disclosure describes a terminal block 1 including a base 10, an elastic piece 20, a conductive terminal 30, a handle 40 and a side cover 50. The elastic piece 20 and the conductive terminal 30 are connected to each other and combined in the base 10. The handle 40 and the side cover 50 are attached to one side of the base 10.

[0038] As shown in FIG. 2, the base 10 has an accommodation space 100. An installation opening 11, an insertion port 12, and a penetration port 13 are defined on the base 10 and communicate with the accommodation space 100. Additionally, the side cover 50 encloses the accommodation space 100. The base 10 includes a pivot portion 14 disposed in the accommodation space 100 and adjacent to the installation opening 11.

[0039] In this embodiment, the insertion port 12 and the installation opening 11 are defined on the same side of the base 10 and located on the side perpendicular to the penetration port 13. Furthermore, the pivot portion 14 includes a cylinder column 141 and a pivot shaft 142 coaxially arranged with each other, and the pivot shaft 142 protrudes from the cylindrical column 141.

[0040] The elastic piece 20 includes a bending section 21, a movable elastic arm 22 and a resisting arm 23. The movable elastic arm 22 and the resisting arm 23 extend respectively from two sides of the bending section 21, and the bending section 21 is attached to (surrounds) the pivot portion 14 (refer to FIG. 4). Specifically, the bending section 21 forms a pivot space 210, and the bending section 21 encircles the cylinder column 141 with the pivot space 210.

[0041] It should be noted that the resisting arm 23 includes a hook 231 disposed on the side facing the movable elastic arm 22. The movable elastic arm 22 is pressed to be engaged with the hook 231 (see FIG. 4).

[0042] Moreover, the conductive terminal 30 includes a conductive section 31 and at least one conducting lead 32 extending from the conductive section 31. The conducting lead 32 is positioned corresponding to the penetration port 13. Moreover, the conductive section 31 includes a U-shaped frame, and one end of the conductive section 31 contacts the resisting arm 23 of the elastic piece 20. In this embodiment, the conducting lead 32 includes an insertion pin. The conducting leads 32 passes through the penetration port 13 of the base 10 (refer to FIG. 4) for being inserted into a circuit board (not shown in figures).

[0043] Moreover, the conductive terminal 30 further includes a supporting plate 33 disposed between the conductive section 31 and the conducting lead 32. In this embodiment, the amount of the conducting lead 32 is two (one pair). The pair of conducting leads 32 are arranged on two sides of the supporting plate 33 opposite to each other.

[0044] The handle 40 is combined in the installation opening 11 of the base 10. Additionally, the handle 40 is pivotally connected to the pivot portion 14 and exposed from one side of the insertion port 12.

[0045] As shown in FIG. 3, the handle 40 includes a body 41, an actuating part 42 and a pressing part 43. The actuating part 42 is exposed from the installation opening 11. The actuating part 42 and the pressing part 43 are located on two sides of the body 41 opposite to each other. Specifically, an axis hole 410 is defined on the body 41. The handle 40 is attached to the base 10 via the pivot portion 14 passing through the axis hole 410 (refer to FIG. 1). Additionally, the actuating part 42 includes an insertion hole for inserting a tool 2, such as a screwdriver.

[0046] As shown in FIG. 4, in this embodiment, the base 10 includes a plurality of positioning parts 15 disposed in the accommodating space 100. Moreover, the resisting arm 23 abuts against one side of the positioning parts 15 and is arranged in the accommodating space 100.

[0047] In more detail, the positioning parts 15 includes a positioning plate 151 and a positioning block 152. One side of the positioning plate 151 is connected to the cylinder column 141 of the pivot portion 14. The positioning block 152 is spacedly disposed on one side of the positioning plate 151. Accordingly, the resisting arm 23 is positioned on the positioning plate 151 and the positioning block 152 and extends to the opposite side of the movable elastic arm 22.

[0048] It should be noted that the pressing part 43 is located adjacent to the movable elastic arm 22. Moreover, users may use a tool 2 to apply force to the actuating part 42. As a result, the handle 40 rotates under the action of external force to make the pressing portion 43 abut against the movable elastic arm 22.

[0049] Please further refer to FIG. 5 and FIG. 6, which depict a cross-sectional view of the handle under an external force in this disclosure and a cross-sectional view of the terminal block in this disclosure when a cable is inserted in. The terminal block 1 is used for connecting a cable 3. When inserting the cable 3 into the terminal block 1, the user inserts a tool 2 into the actuating part 42 and applies force to rotate the handle 40 around the pivot portion 14. Furthermore, the pressing portion 43 of the handle 40 may push against the movable elastic arm 22 to make the end of the movable elastic arm 22 be engaged with the hook 231 of the resisting arm 23.

[0050] It is worth noticing that the body 41 of the handle 40 includes a protrusion column 44 disposed on the side facing the accommodating space 100 (also refer to FIG. 3). Furthermore, when the end of the movable elastic arm 22 is engaged with the hook 231 of the resisting arm 23, the elastic piece 20 achieves self-locking. At the same time, the handle 40 is positioned (stopped) at a specific angle by the push of the movable elastic arm 22 through the protrusion column 44. Therefore, the handle 40 may not return to its original position.

[0051] Furthermore, when the end of the movable elastic arm 22 is disengaged from the hook 231, the elastic piece 20 releases its self-locking mechanism. Then, the handle 40 returns to its initial position along with the elastic piece 20. Accordingly, users may clearly determine whether the elastic piece 20 is in the open state based on the position of the handle 40 during connection.

[0052] As shown in FIG. 6, the cable 3 is inserted into the accommodation space 100 of the base 10 through the insertion port 12 to be electrically connected with the conducting lead 32. Additionally, when the cable 3 is inserted to the position of the resisting arm 23 and pushes against the resisting arm 23, the resisting arm 23 is moved by the push from the cable 3 to make the movable elastic arm 22 to be disengaged from the engagement of the hook 231.

[0053] It is worth noticing that the actuating part 42 of the handle 40 is adjacent to the pivot portion 14. Since the distance between the actuating part 42 and the pivot portion 14 is shorter compared to the distance between the movable elastic arm 22 and the pivot portion 14. Thus, the actuating part 42, when subjected to external force, requires only a shorter travel distance for a larger displacement of the movable elastic arm 22. Therefore, the volume of the base 10 may be kept from being excessively large, thereby achieving the purpose of reducing the overall size.

[0054] Please also refer to FIG. 7, which depicts a cross-sectional view of the cable positioned on the terminal block in this disclosure. Once the external force acting on the cable 3 is removed, the resisting arm 23 returns to its original position due to elastic force. Then, the movable elastic arm 22 presses against the cable 3 to secure the cable 3 within the base 10.

[0055] Please further refer to FIG. 8, which depicts another embodiment of the terminal block with a handle in this disclosure. In this embodiment, the terminal block 1 includes a plurality of base 10. Additionally, the bases 10 are arranged side by side, and the outermost base 10 is combined with a side cover 50. Additionally, the quantities of the elastic piece 20, the conductive terminal 30 (not shown in figures), and the handle 40 are correspondingly disposed in multiple and combined on the bases 10.

[0056] Please refer to FIG. 9, which illustrates another embodiment of the handle in this disclosure. In this embodiment, the terminal block 1 includes a plurality of base 10 arranged side by side, and the outermost base 10 is combined with a side cover 50. Furthermore, a plurality of handles 40 are correspondingly arranged and combined on the bases 10. The difference between this embodiment and the previous embodiment is the configuration of the actuating part 42 of each handle 40, which is designed as a pressure plate. Accordingly, when using the terminal block 1, users do not need additional tools. Users may directly press the actuating part 42 with their fingers to rotate the handle 40, thereby increasing the convenience of use.

[0057] Please refer to FIG. 10 and FIG. 11, which depict a perspective schematic view and a cross-sectional view of another embodiment of the terminal block with a handle in this disclosure. In this embodiment, the terminal block 1a includes a base 10a, an elastic piece 20a, a conductive terminal 30a, a handle 40a and a side cover 50a. The elastic piece 20a and the conductive terminal 30a are combined in the base 10a. The handle 40a is attached to one side of the base 10a. The side cover 50a is coupled to one side of the base 10a. The difference between this embodiment and the previous embodiment is the configuration of the conductive terminal 30a.

[0058] In this embodiment, the conductive terminal 30a includes a conductive section 31a and a pair of conducting leads 32 extending from the conductive section 31a. Furthermore, one end of the conductive section 31a contacts the elastic piece 20a. The conducting leads 32a are disposed corresponding to the penetration port 13a of the base 10. In this embodiment, the pair of conducting leads 32a is a pair of clamping legs. The pair of conducting leads 32a is utilized to be connected with a cable (not shown in figures) inserted through the penetration port 13a of the base 10a.

[0059] Please further refer to FIG. 12, which depicts a cross-sectional view of still another embodiment of the terminal block with a handle in this disclosure. In this embodiment, a terminal block 1b includes a base 10b, a pair of elastic pieces 20b, a pair of conductive terminals 30b and a pair of handles 40b. The pair of elastic pieces 20b and the pair of conductive terminals 30b are combined in the base 10b. The pair of handles 40b is positioned on one side of the base 10b, spaced apart from each other, with each handle 40b corresponding to pressing against one of the elastic pieces 20b.

[0060] Specifically, the base 10b has a pair of accommodating spaces 100b separately defined and a pair of installation openings 11b, a pair of insertion ports 12b and a pair of penetration ports 13b that communicate with the pair of accommodation spaces 100b respectively. Each installation opening 11b, each insertion port 12b and each penetration ports 13b are respectively disposed corresponding to each accommodating space 100b. The base 10b is respectively formed with a pivot portion 14b in each accommodation space 100b, and the pivot portion 14b is adjacent to the corresponding installation opening 11b. Each elastic piece 20b encircles the pivot portion 14b. Additionally, each conductive terminal 30 includes a conductive section 31b and a conducting lead 32b extending from the conductive section 31b. One end of the conductive section 31b contacts the elastic piece 20b. The conducting lead 32b is disposed corresponding to the penetration port 13b.

[0061] It should be noted that the ends of the pair of conductive terminals 30b are connected and positioned on one side of the pair of penetration ports 13b. Consequently, the pair of insertion ports 12b may be inserted by a pair of cables (not shown in figures). The pair of cables may be connected to external wires inserted through the pair of penetration ports 13b via the pair of elastic pieces 20b and conductive terminals 30b.

[0062] While this disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of this disclosure set forth in the claims.
