[0007] In an embodiment of the present invention, the insertion opening and the installation opening are arranged on the same side of the base and on one side perpendicular to the through opening.

[0008] In an embodiment of the present invention, the pivot joint portion includes a cylindrical column and a pivot shaft that are coaxially arranged, and the pivot shaft protrudes on the cylindrical column.

[0009] In an embodiment of the present invention, a pivot joint space is formed in the bent section, and the bent section sleeves the cylindrical column with the pivot joint space.

[0010] In an embodiment of the present invention, several positioning portions are formed in the accommodating space of the base, and the abutting arm is arranged in the accommodating space by abutting against one side of the several positioning portions.

[0011] In an embodiment of the present invention, the several positioning portions include a positioning plate and a positioning block. One side of the positioning plate is connected to the cylindrical column, and the positioning blocks are spaced on one side of the positioning plate.

[0012] In an embodiment of the present invention, a hook is formed on one side of the abutting arm facing the movable elastic arm, and the movable elastic arm is pushed and abutted against the hook.

[0014] In an embodiment of the present invention, the pair of conductive pins are a pair of insertion pins.

[0015] In an embodiment of the present invention, the pair of conductive pins are a pair of clamping pins.

[0016] In an embodiment of the present invention, the conductive section is arranged as a U-shaped frame.

[0017] In an embodiment of the present invention, the handle includes a body, an acting portion and a pressing portion. The acting portion exposes the installation opening, the pressing portion abuts against the movable elastic arm, and the acting portion and the pressing portion are located on opposite sides of the body.

[0018] In an embodiment of the present invention, the body is provided with a shaft hole, and the handle is combined with the base by passing the pivot joint portion through the shaft hole.

[0019] In an embodiment of the present invention, a convex column is arranged on one side of the body facing the accommodating space, and the handle is pushed by the movable elastic arm through the convex column and stops at a specific angle.

[0020] In an embodiment of the present invention, the acting portion is a socket.

[0021] In an embodiment of the present invention, the acting portion is a pressing plate.

[0022] In an embodiment of the present invention, the terminal block further includes a side cover, and the side cover is combined on one side of the base and covers the accommodating space.

[0023] In an embodiment of the present invention, the number of bases is several and they are arranged in parallel connection, and the outermost base is combined with a side cover. The number of elastic pieces, connection terminals and handles is correspondingly set to several and they are combined on several of these bases.

[0024] In an embodiment of the present invention, the base has a pair of accommodating spaces that are separated, and a pair of installation openings, a pair of insertion openings and a pair of passing openings that respectively communicate with the pair of accommodating spaces.

[0070] The detailed description and technical content of the present invention are described below in conjunction with the drawings. However, the attached drawings are only for reference and illustration purposes and are not used to limit the present invention.

[0071] Please refer to Figures 1 to 4 , which are respectively the three-dimensional external view schematic diagram of the terminal block with a handle of the present invention, the three-dimensional exploded schematic diagram of the terminal block with a handle, the three-dimensional external view schematic diagram of the handle, and the combined cross-sectional view of the terminal block with a handle. As Figure 1 shown, the present invention is a terminal block 1 with a handle (hereinafter referred to as terminal block 1), including a base 10, an elastic sheet 20, a conductive connection terminal 30, a handle 40, and a side cover 50. The elastic sheet 20 and the conductive connection terminal 30 are conductively connected to each other and combined in the base 10. The handle 40 is disposed on one side of the base 10. The side cover 50 is combined on one side of the base 10.

[0072] As Figure 2 shown, the base 10 has a receiving space 100 and an installation opening 11, an insertion opening 12, and a passing opening 13 that communicate with the receiving space 100. The side cover 50 covers the receiving space 100. The base 10 is formed with a pivoting portion 14 in the receiving space 100, and the pivoting portion 14 is adjacent to the installation opening 11.

[0073] In this embodiment, the installation opening 11 and the insertion opening 12 are provided on the same side of the base 10 and are located on one side perpendicular to the through opening 13. The pivoting portion 14 includes a cylindrical column 141 and a pivot shaft 142 that are coaxially arranged. The pivot shaft 142 protrudes on the cylindrical column 141.

[0074] The elastic piece 20 includes a bent section 21, a movable elastic arm 22, and a abutting arm 23. The movable elastic arm 22 and the abutting arm 23 extend on both sides of the bent section 21 respectively, and the bent section 21 is sleeved on the pivoting portion 14 (see Figure 4 ). Specifically, the bent section 21 is formed with a pivoting space 210, and the bent section 21 is sleeved on the cylindrical column 141 of the pivoting portion 14 with the pivoting space 210.

[0075] It should be noted that a hook 231 is formed on one side of the abutting arm 23 facing the movable elastic arm 22. The movable elastic arm 22 will abut against the hook 231 after being pushed by the handle 40 (see Figure 4 ).

[0076] Furthermore, the connection terminal 30 includes a connection section 31 and at least one connection pin 32 extending from the connection section 31. The connection pin 32 is arranged corresponding to the through opening 13 of the base 10. The connection section 31 is arranged as a U-shaped frame, and one end of the connection section 31 contacts the abutting arm 23 of the elastic piece 20. In this embodiment, the connection pin 32 is a plug pin. The connection pin 32 passes through the through opening 13 of the base 10 (see Figure 4 ) for plugging into a circuit board (not shown).

[0077] In addition, the connection terminal 30 further includes a support plate 33. The support plate 33 is arranged between the connection section 31 and the connection pin 32. In this embodiment, the number of the connection pins 32 is a pair. The pair of connection pins 32 are arranged on opposite sides of the support plate 33.

[0078] The handle 40 is combined in the installation opening 11 of the base 10. The handle 40 is pivotally connected to the pivoting portion 14 and is exposed on one side of the insertion opening 12.

[0079] As Figure 3 shown, the handle 40 includes a body 41, an acting portion 42, and a pressing portion 43. The acting portion 42 is exposed outside the installation opening 11. The acting portion 42 and the pressing portion 43 are located on opposite sides of the body 41. Specifically, the body 41 is provided with a shaft hole 410. The handle 40 is combined with the base 10 by passing the pivoting portion 14 through the shaft hole 410 (see Figure 1 ). In addition, the acting portion 42 is arranged as a socket for inserting a tool 2 such as a screwdriver.

[0080] AsFigure 4 As shown, in this embodiment, several positioning portions 15 are formed in the accommodation space 100 of the base 10. The abutting arm 23 is disposed in the accommodation space 100 by abutting against one side of the positioning portions 15.

[0081] More specifically, the positioning portions 15 include 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 pivoting portion 14. The positioning block 152 is spaced apart on one side of the positioning plate 151. Accordingly, the abutting 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.

[0082] It should be noted that the pressing portion 43 abuts against the movable elastic arm 22. In addition, the user can apply a force to the acting portion 42 through a tool 2. Accordingly, the handle 40 can pivot under an external force, so that the pressing portion 43 pushes against the movable elastic arm 22.

[0083] Please refer to Figure 5 and Figure 6 , which are cross-sectional views of the handle of the present invention when subjected to an external force and when the terminal block is inserting a cable. The terminal block 1 of the present invention is used to insert a cable 3. When the cable 3 is inserted into the terminal block 1, the user inserts the tool 2 into the acting portion 42 and applies a force, so that the handle 40 can rotate around the pivoting portion 14 as the center. The pressing portion 43 of the handle 40 will push against the movable elastic arm 22, so that the end of the movable elastic arm 22 is buckled on the hook 231 of the abutting arm 23.

[0084] It should be noted that a convex column 44 is provided on one side of the body 41 of the handle 40 of the present invention facing the accommodation space 100 (see also Figure 3 ). When the end of the movable elastic arm 22 is buckled on the hook 231 of the abutting arm 23, the elastic piece 20 is locked. At this time, the handle 40 is pushed against by the movable elastic arm 22 through the convex column 44 and stops at a specific angle, so the handle 40 will not return to its original position.

[0085] Furthermore, when the end of the movable elastic arm 22 is disengaged from the buckle of the hook 231, the elastic piece 20 will be unlocked. At this time, the handle 40 will return to its starting position with the elastic piece 20. Accordingly, when wiring, the user can clearly distinguish whether the elastic piece 20 is in the open state from the position of the handle.

[0086] As Figure 6As shown, the cable 3 can pass through the insertion port 12 into the accommodating space 100 of the base 10, thereby electrically connecting to the connection pin 32. In addition, when the cable 3 extends to the position of the abutting arm 23, it will push against the abutting arm 23. At this time, the abutting arm 23 moves due to being pushed by the cable 3, and the movable elastic arm 22 will disengage from the buckle of the hook 231.

[0087] It should be noted that the acting portion 42 of the handle 40 of the present invention is adjacent to the pivoting portion 14. Since the distance between the acting portion 42 and the pivoting portion 14 is shorter than the distance between the movable elastic arm 22 and the pivoting portion 14. Therefore, when the acting portion 42 moves a shorter stroke under an external force, the movable elastic arm 22 can be displaced greatly; accordingly, the volume of the base 10 can be prevented from being too large, achieving the purpose of reducing the overall appearance.

[0088] Please refer to Figure 7 , which is a cross-sectional view of the cable of the present invention positioned on the terminal block. After the external force acting on the cable 3 is removed, the abutting arm 23 returns to its original position by elastic force. At this time, the movable elastic arm 22 presses against the cable 3 to position the cable 3 in the base 10.

[0089] Please continue to refer to Figure 8 , which is another embodiment of the terminal block with a handle of the present invention. The terminal block 1 of the present invention may include a plurality of bases 10. In addition, the bases 10 are arranged in parallel, and the outermost base 10 is combined with a side cover 50. The number of the elastic pieces 20, the connection terminals 30 (not shown in the figure), and the handles 40 is correspondingly set to be a plurality and combined on the bases 10.

[0090] Please refer to Figure 9 , which is another embodiment of the handle of the present invention. In this embodiment, the terminal block 1' includes a plurality of bases 10 arranged in parallel, and the outermost base 10 is combined with a side cover 50. The handles 40' are correspondingly set to be a plurality and combined on the bases 10. The difference between this embodiment and the previous embodiment is that the acting portion 42' of each handle 40' is set as a pressing plate. Accordingly, when using the terminal block 1' of the present invention, no additional tool is required, and the user can directly press the acting portion 42' with the finger to rotate the handle 40', increasing the convenience during use.

[0091] Please refer to Figure 10 and Figure 11, respectively, are a perspective external view and a cross-sectional view of another embodiment of the terminal block with a handle according to the present invention. In this embodiment, the terminal block 1a with a handle includes a base 10a, an elastic piece 20a, a conducting terminal 30a, a handle 40a, and a side cover 50a. The elastic piece 20a and the conducting terminal 30a are combined in the base 10a. The handle 40a is disposed on one side of the base 10a. The side cover 50a is combined on one side of the base 10a. The difference in this embodiment lies in the form of the conducting terminal 30a.

[0092] In this embodiment, the conducting terminal 30a includes a conducting section 31a and a pair of conducting legs 32a extending from the conducting section 31a. One end of the conducting section 31a contacts the elastic piece 20a. The conducting legs 32a are arranged corresponding to the through holes 13a of the base 10a. In this embodiment, the pair of conducting legs 32a are a pair of clamping legs. The pair of conducting legs 32a are used to conduct a wire (not shown) passing through the through holes 13a of the base 10a.

[0093] Please continue to refer to Figure 12 , is a cross-sectional view of another embodiment of the terminal block with a handle according to the present invention. In this embodiment, the terminal block 1b with a handle includes a base 10b, a pair of elastic pieces 20b, a pair of conducting terminals 30b, and a pair of handles 40b. The pair of elastic pieces 20b and the pair of conducting terminals 30b are combined in the base 10b. The pair of handles 40b are spaced apart on one side of the base 10b and respectively press the pair of elastic pieces 20b.

[0094] Specifically, the base 10b has a pair of accommodating spaces 100b that are separated and a pair of mounting openings 11b, a pair of insertion openings 12b, and a pair of through holes 13b that respectively communicate with the pair of accommodating spaces 100b. Each mounting opening 11b, each insertion opening 12b, and each through hole 13b are respectively arranged corresponding to each accommodating space 100b. The base 10b is respectively formed with a pivoting portion 14b in each accommodating space 100b, and the pivoting portion 14b is adjacent to the corresponding mounting opening 11b. Each elastic piece 20b is sleeved on each pivoting portion 14b. In addition, each conducting terminal 30b includes a conducting section 31b and a conducting leg 32b extending from the conducting section 31b. One end of the conducting section 31b contacts the elastic piece 20b, and the conducting leg 32b is arranged corresponding to the through hole 13b.

[0095] It should be noted that the ends of the pair of conducting terminals 30b are connected and located on one side of the pair of through holes 13b. Accordingly, the pair of insertion openings 12b can be used to insert a pair of cables (not shown). The pair of cables can conduct external wires inserted through the pair of through holes 13b through the pair of elastic pieces 20b and the pair of conducting terminals 30b, so as to connect to an external device.

[0096] The above are only the preferred embodiments of the present invention and are not intended to limit the scope of the patent of the present invention. Equivalent changes using the patent spirit of the present invention shall all fall within the scope of the patent of the present invention.
