Description

Technical Field

[0001] The utility model relates to a terminal block structure, and particularly to a terminal block structure with horizontal wire inlet. Background Art

[0002] A terminal block is a common connection component, which has been widely used in fields such as industrial communication with a large amount of information, industrial equipment with close integration between devices, the power industry for enhancing the reliability and safety of the power system, and industrial control with a higher degree of automation.

[0003] The traditional terminal block structure includes a plastic housing and a connection terminal module installed in the plastic housing. The connection terminal module includes upper and lower elastic pieces fixed on both sides of the plastic housing. One end of the upper elastic piece has a free end that can abut against the lower elastic piece. When a wire is inserted between the free end of the upper elastic piece and the lower elastic piece, the free end of the upper elastic piece can reset downward, so that the wire is clamped between the free end of the upper elastic piece and the lower elastic piece to achieve electrical connection between the wire and the upper and lower elastic pieces.

[0004] However, the above-mentioned terminal block structure is provided with a wire inlet for inserting a wire, but the axial direction of the wire inlet usually forms an acute angle between 30° and 60° with the horizontal plane, that is, the wire inlet is inclined relative to the horizontal plane. After the wire is inserted into the terminal block structure, the wire exposed outside the terminal block structure needs to be manually bent to be leveled. However, most wires are hard in hardness or thick in diameter, making it inconvenient for users to use due to difficult bending.

[0005] In view of this, the creator specifically studied the above-mentioned existing technology, and with the application of theory, tried his best to solve the above problems, which became the goal of the creator's improvement. Summary of the Utility Model

[0006] The utility model provides a terminal block structure with horizontal wire inlet, which utilizes the axial direction of each horizontal wire slot to be parallel to the transverse piece, so as to achieve the advantages of natural leveling of the inserted wire and improved use convenience of the terminal block structure.

[0007] In an embodiment of the present utility model, the present utility model provides a terminal block structure with horizontal wire inlet, including: an insulating base, which has an internal cavity and two fixing blocks extending in the cavity, and two horizontal wire grooves communicating with the cavity are arranged outside the insulating base; and a connection terminal module, which is accommodated in the cavity, and the connection terminal module includes: a fixed terminal, which has a transverse piece and two vertical pieces extending upward from both ends of the transverse piece, each of the fixing blocks and the transverse piece are respectively arranged on the upper and lower sides of each of the horizontal wire grooves, and each of the horizontal wire grooves is arranged with its axis parallel to the transverse piece; and two toggle terminals, which are abutted against the two fixing blocks, an outer end of each of the toggle terminals extends a toggle piece arranged outside each of the vertical pieces and blocking between each of the horizontal wire grooves and the cavity, and an inner end of each of the toggle terminals extends a stop piece corresponding to each of the toggle pieces.

[0008] Based on the above, each of the horizontal wire grooves is arranged with its axis parallel to the transverse piece. When wires or cables and other wire materials are inserted into the horizontal wire grooves, the wires or cables and other wire materials exposed outside the terminal block structure are naturally leveled on the horizontal plane, eliminating the step of manually bending the wires or cables and other wire materials in the known technology, so as to achieve the advantages that the terminal block structure has natural leveling of inserted wire materials and improved use convenience.

[0047] The detailed description and technical contents of the present invention will be described below with reference to the accompanying drawings. However, the accompanying drawings are only for illustrative purposes and are not intended to limit the present invention.

[0048] Please refer to Figures 1 to 7 As shown, the utility model provides a terminal block structure for horizontal incoming lines. The terminal block structure for horizontal incoming lines (hereinafter referred to as the terminal block structure 10 ) mainly includes an insulating base 1 and a connecting terminal module 2 .

[0049] like Figures 1 to 7 As shown, the insulating base 1 is made of plastic material, a cavity 11 is provided inside the insulating base 1 and two fixing blocks 12 are extended and located in the cavity 11, and two connecting grooves 13 and two horizontal threading grooves 14 are provided outside the insulating base 1 to connect with the cavity 11, the two connecting grooves 13 are arranged above the cavity 11, and the bottom of the insulating base 1 has a track clamping portion 4 that can be engaged on a track (not shown).

[0050] Among them, two horizontal wire threading grooves 14 are respectively opened from the left and right sides of the insulating base 1, so that the two horizontal wire threading grooves 14 are arranged on the left and right sides of the cavity 11, and the axial directions D of the two horizontal wire threading grooves 14 intersect on the same horizontal line. The two fixing blocks 12 are located in the upper section of the cavity 11, and the two horizontal wire threading grooves 14 are connected to the lower section of the cavity 11.

[0051] The detailed description is as follows. The two fixing blocks 12 are symmetrical in shape. A through hole 121 is provided on the top surface of each fixing block 12 and an arc-shaped end 123 is provided at one end of the fixing block 12. A recessed hole 1211 is provided on the inner wall of each through hole 121. A lower protrusion 15 and several protrusions 16 located in the cavity 11 are further extended from the inside of the insulating base 1.

[0052] like Figures 1 to 7 As 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.

[0053] Further explanation is as follows: the fixed terminal 21 has a horizontal piece 211 arranged corresponding to the bottom edge of each horizontal wire groove 14 and two vertical pieces 212 extending upward from both ends of the horizontal piece 211. Each fixed block 12 and the horizontal piece 211 are respectively arranged on the upper and lower sides of each horizontal wire groove 14, and each horizontal wire groove 14 is arranged with its axial direction D parallel to the horizontal piece 211.

[0054] Among them, the middle section of the horizontal piece 211 is blocked by the downward protruding post 15. The horizontal piece 211 is provided with several notches 2111, and each bump 16 is engaged with each notch 2111, so that the horizontal piece 211 is stably positioned in the cavity 11. Each vertical piece 212 passes through each through hole 121, so that the two vertical pieces 212 are inserted into the two fixing blocks 12.

[0055] In addition, each actuatable terminal 22 has a U-shaped bent piece 221. The middle of each U-shaped bent piece 221 abuts against each arc end 123, so that the two actuatable terminals 22 are stably abutted against the two fixing blocks 12. The outer ends of each actuatable terminal 22 extend with an actuatable piece 223 disposed outside each vertical piece 212 and blocking between each horizontal wire groove 14 and the cavity 11, and the inner ends of each actuatable terminal 22 extend with a stop piece 222 disposed corresponding to each actuatable piece 223. Each stop piece 222 and each actuatable piece 223 extend from both ends of each U-shaped bent piece 221.

[0056] Furthermore, each vertical piece 212 is provided with a clamping groove 23, and the inner side of each U-shaped bent piece 221 extends with a clamping tongue 24. Each clamping tongue 24 is engaged with each clamping groove 23, and the end of each clamping tongue 24 extends into each through hole 121 and is engaged with each concave hole 1211.

[0057] Each vertical piece 212 is provided with a hollow opening 2121 disposed opposite to each horizontal wire groove 14. Each actuatable piece 223 can penetrate into each hollow opening 2121. Each clamping groove 23 is recessed from the inner peripheral edge of each hollow opening 2121. The end of each stop piece 222 is bent with an inverted L-shaped stop portion 2221. Each inverted L-shaped stop portion 2221 is used to stop the end of a wire or cable such as a wire 100.

[0058] In addition, the shape of the integrally extended horizontal piece 211 and each vertical piece 212 is a U shape, and the shape of each actuatable terminal 22 is an inverted V shape, so that the fixed terminal 21 and the two actuatable terminals 22 that abut against each other jointly enclose a butterfly-shaped frame.

[0059] As Figures 1 to 7 shown, the terminal block structure 10 of the present utility model further includes two inner push handles 3. Each inner push handle 3 is accommodated in each communication 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 actuatable piece 223.

[0060] The details are as follows. Each internal pushing 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 disposed above each U-shaped bending piece 221. The other end of each U-shaped handle 31 has a movable end 32 that abuts against each actuating piece 223, and a pushing notch 33 exposed in each communication groove 13 is provided in the middle of each U-shaped handle 31. By inserting a flat plate-shaped object such as a screwdriver (not shown in the figure) into the pushing notch 33, the U-shaped handle 31 can be driven to rotate, so that the movable end 32 pushes against the actuating piece 223 and moves into the horizontal wire groove 14.

[0061] As Figures 4 to 7 shown, in the usage state of the terminal block structure 10 of the present utility model, by inserting a flat plate-shaped object such as a screwdriver into the pushing notch 33, the internal pushing handle 3 can be driven to rotate, thereby driving the movable end 32 to push against the actuating piece 223 and move into the horizontal wire groove 14. Then, a wire material 100 such as a wire or a cable is inserted into the horizontal wire groove 14 until it is blocked by the blocking piece 222, and then the internal pushing handle 3 can be released, so that the actuating piece 223 returns to the position blocking between each horizontal wire groove 14 and the cavity 11. Finally, the wire material 100 such as a wire or a cable is clamped between the transverse piece 211 and the actuating piece 223, that is, the wire material 100 such as a wire or a cable is clamped between the fixed terminal 21 and the actuating terminal 22, and the wiring operation of the terminal block structure 10 is completed.

[0062] In addition, the bottom of the insulating base 1 in the present utility model can be clamped on the track through the track clamping portion 4, so that the transverse piece 211 is arranged parallel to the horizontal plane. Each horizontal wire groove 14 is arranged with its axis D parallel to the transverse piece 211, so the axis D of each horizontal wire groove 14 is also parallel to the horizontal plane. When a wire material 100 such as a wire or a cable is inserted into the horizontal wire groove 14, the wire material 100 such as a wire or a cable exposed outside the terminal block structure 10 is naturally leveled on the horizontal plane, omitting the step of manually bending the wire material 100 such as a wire or a cable in the prior art, so as to achieve the advantages that the terminal block structure 10 has natural leveling of the inserted wire material 100 and improved usability.

[0063] Furthermore, in the prior art, the inlet is inclined relative to the horizontal plane. In the present utility model, since the axis D of the horizontal wire groove 14 is parallel to the horizontal plane, and the internal pushing handle 3 is adjusted to be rotary and is located above the actuating terminal 22 and close to the actuating piece 223, the internal pushing handle 3 can smoothly push open the actuating piece 223 with a smaller thrust compared to the prior art, so as to achieve the characteristic that the terminal block structure 10 is labor-saving in insertion.

[0064] The above is only the preferred feasible embodiment of the present utility model, and it does not limit the patent scope of the present utility model accordingly. All equivalent structural changes made by using the description and the drawings of the present utility model are reasonably included in the scope of the rights of the present utility model, and it is hereby clarified.
