Description

Technical Field

[0001] The utility model relates to a terminal block structure, and in particular to a terminal block structure and a connecting terminal module thereof. Background Art

[0002] Terminal Block is a common connection component. It has been widely used in industrial communications with huge amounts of information, industrial equipment with close integration between devices, the power industry to improve the reliability and safety of power systems, and more highly automated industrial control.

[0003] The traditional terminal block structure includes a plastic frame and a connecting terminal module installed on the plastic frame. The connecting terminal module includes an upper spring sheet and a lower spring sheet fixed on both sides of the plastic frame. One end of the upper spring sheet has a free end that can abut against the lower spring sheet. When the wire or cable is inserted between the free end of the upper spring sheet and the lower spring sheet, the free end of the upper spring sheet can be reset to the lower spring sheet, so that the wire or cable is clamped between the free end of the upper spring sheet and the lower spring sheet, so as to achieve electrical connection between the wire or cable and the upper spring sheet and the lower spring sheet.

[0004] However, it is common to insert a flat plate-like object such as a screwdriver between the upper spring sheet and the plastic frame, or to provide a tongue that can move or pivot against the upper spring sheet to press the free end of the upper spring sheet away from the lower spring sheet. However, since the supporting strength of plastic is weaker than that of metal, the upper spring sheet is easily moved downward and separated from the installation position of the plastic frame, resulting in a greater friction between the upper spring sheet and the plastic frame when the upper spring sheet is pressed next time, thereby affecting the wiring speed and feel of the terminal block structure.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] Please refer to Figures 1 to 8 As shown, the utility model provides a terminal block structure and a connecting terminal module thereof. The terminal block structure 10 mainly includes an insulating base 1 and a connecting terminal module 2 . The connecting terminal module 2 mainly includes a fixed terminal 21 and two movable terminals 22 .

[0027] like Figures 2 to 8 As shown, the insulating base 1 is made of plastic material, and a cavity 11 is provided inside the insulating base 1, two fixing blocks 12 extending from the cavity 11, and two connecting grooves 13 and two threading grooves 14 connecting the cavity 11 are provided outside the insulating base 1, the two connecting grooves 13 are arranged above the cavity 11, and the two threading grooves 14 are arranged on the left and right sides of the cavity 11.

[0028] The detailed description is as follows: the top surface of each fixing block 12 is provided with a through hole 121 and a recessed groove 122 which are interconnected, and one end of the fixing block 12 has an arc-shaped end 123, and the bottom wall of each recessed groove 122 is provided with a sunken hole 1221, and each sunken hole 1221 is connected to each through hole 121, and the appearance of the two fixing blocks 12 is symmetrical to each other on the left and right, and the inside of the insulating base 1 further extends with a lower protrusion 15 and a plurality of protrusions 16 located in the cavity 11.

[0029] like Figures 1 to 8As shown, the connection terminal module 2 is accommodated in the cavity 11, and the connection terminal module 2 includes a fixed terminal 21 and two movable terminals 22. The fixed terminal 21 and the movable terminal 22 are respectively made of conductive metal materials, and the thickness of the fixed terminal 21 is greater than the thickness of each movable terminal 22.

[0030] Further explanation is as follows. The fixed terminal 21 has a horizontal piece 211 arranged corresponding to the bottom edge of each threading groove 14 and two vertical pieces 212 extending upward from both ends of the horizontal piece 211. The middle section of the horizontal piece 211 is stopped by the lower protrusion 15. The horizontal piece 211 is provided with a plurality of notches 2111. Each protrusion 16 is engaged with each notch 2111, so that the horizontal piece 211 is stably fixed in the cavity 11. The two vertical pieces 212 are bent outward to have two supporting elastic arms 213. Each vertical piece 212 is penetrated by each through hole 121, and each supporting elastic arm 213 is engaged with each recessed groove 122, so that the two supporting elastic arms 213 are against the two fixed blocks 12.

[0031] In addition, each movable terminal 22 has a U-shaped bending piece 221, and the middle of each U-shaped bending piece 221 rests against each arc end 123 and the inner side rests against each supporting elastic arm 213, so that the two movable terminals 22 can stably rest on the two supporting elastic arms 213 and the two fixed blocks 12. The outer end of each movable terminal 22 is extended with a movable piece 223 configured on the outside of each upright piece 212 and blocked between each threading groove 14 and the cavity 11, and the inner end of the movable terminal 22 is extended with a stop piece 222 corresponding to each movable piece 223. Each stop piece 222 and each movable piece 223 are extended from the two ends of each U-shaped bending piece 221.

[0032] Furthermore, each supporting elastic arm 213 is provided with a groove 23, and each movable terminal 22 extends with a tenon 24, each tenon 24 is engaged with each groove 23 and embedded in each sunken hole 1221, and the end of each tenon 24 extends into each through hole 121 and rests on the inner side of the junction between each upright piece 212 and each supporting elastic arm 213.

[0033] In addition, each upright piece 212 is provided with a hollow opening 2121 arranged opposite to each threading groove 14, and each movable piece 223 can be inserted into each hollow opening 2121. The end of each stopper piece 222 is bent to form an inverted L-shaped stopper 2221, and each inverted L-shaped stopper 2221 is used to stop the end of a wire 100 such as a conductor or cable.

[0034] In addition, the integrally extended vertical pieces 212 and the supporting elastic arms 213 are in a U-shape, and the movable terminals 22 are in an inverted V-shape, so that the fixed terminals 21 and the two movable terminals 22 that abut against each other jointly form a butterfly-shaped frame.

[0035] like Figures 2 to 8 As shown, the terminal block structure 10 of the present invention further includes two inner push handles 3 , each inner push handle 3 is accommodated in each connecting groove 13 , one end of each inner push handle 3 is pivotally connected to the insulating base 1 and the other end of each inner push handle 3 abuts against each movable piece 223 .

[0036] The detailed description is as follows. Each inner push handle 3 is a U-shaped handle 31. One end of each U-shaped handle 31 is pivotally connected to the insulating base 1 and is arranged above each U-shaped bending piece 221. The other end of the U-shaped handle 31 has a movable end 32 that abuts against each movable piece 223 and a pushing recess 33 exposed to each connecting groove 13. By inserting a flat plate-like object such as a screwdriver (not shown in the figure) into the pushing recess 33, the U-shaped handle 31 can be driven to rotate, so that the movable end 32 pushes the movable piece 223 and moves toward the threading groove 14.

[0037] like Figures 5 to 8 As shown, the terminal block structure 10 and the connecting terminal module 2 of the utility model are in use. By inserting a flat plate-like object such as a screwdriver into the pushing recess 33, the inner push handle 3 can be driven to rotate, thereby driving the movable end 32 to push the movable piece 223 to move toward the threading groove 14. After that, the wires 100 such as wires or cables are inserted into the threading groove 14 until they are stopped by the stop piece 222. The inner push handle 3 can be released to allow the movable piece 223 to reset to the position blocked between each threading groove 14 and the cavity 11. Finally, the wires 100 such as wires or cables are clamped between the horizontal piece 211 and the movable piece 223, that is, the wires 100 such as wires or cables are clamped between the fixed terminal 21 and the movable terminal 22, and the wiring operation of the terminal block structure 10 is completed.

[0038] In addition, the movable terminal 22 of the utility model abuts against the arc-shaped end 123 of the insulating base 1 and the supporting spring arm 213 of the fixed terminal 21. Since the metal material of the supporting spring arm 213 has better structural strength than the plastic material of the arc-shaped end 123, when the movable piece 223 is pushed into the threading groove 14 by the inner push handle 3, although the U-shaped bent piece 221 of the movable terminal 22 will exert pressure on the arc-shaped end 123 and the supporting spring arm 213, due to the enhanced strength of the supporting spring arm 213, the U-shaped bent piece 221 of the movable terminal 22 is not easy to rotate and deviate from the original position, and the contact area between the U-shaped bent piece 221 and the fixed block 12 is reduced, thereby reducing the friction between the different materials to greatly reduce the rotation force of the U-shaped bent piece 221, so that the movable terminal 22 can remain in the original position and not deviate during long-term use, so as to achieve the advantages of the terminal block structure 10 and the connecting terminal module 2 having long-term stable wiring speed and hand feel.

[0039] In addition, the supporting elastic arm 213 is provided with a groove 23, and the movable terminal 22 is extended with a tenon 24, which is engaged with the groove 23, and the end of the tenon 24 is against the inner side of the junction of the vertical piece 212 and the supporting elastic arm 213, so that the movable terminal 22 and the fixed terminal 21 can be more firmly against each other, so as to improve the effectiveness of the movable terminal 22 remaining in the original position and not being displaced during long-term use.

[0040] The above-described embodiments are only preferred embodiments for fully illustrating the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or changes made by technicians in the technical field on the basis of the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the claims.
