Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of terminal block flow guiding structure, and in particular to a terminal block flow guiding structure. Background Technology
[0002] Terminal blocks are key components in electrical connections, used to safely and reliably connect wires, ensure circuit continuity, and facilitate installation, maintenance, and expansion. Their core functions include conducting electricity, insulating, and securing wires.
[0003] Commonly used terminal block current-guiding structures use screws and washers to fix cables. During installation, workers need to place the cable under the washer and then tighten the screw. This method is prone to errors during installation, such as improper placement of the wire end, resulting in a small contact area between the terminal block and the cable, leading to unstable current carrying capacity. Furthermore, some conductors may be exposed, creating a safety hazard. Moreover, loosening screws with a screwdriver can easily cause them to fall out, requiring the wire to be re-inserted into the port, which is inconvenient. Each wire requires a separate screw, resulting in low installation efficiency. To overcome these disadvantages, this utility model provides a terminal block current-guiding structure. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a terminal block current guiding structure.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a terminal block current guiding structure, including a first conductive plate, with insulating shells provided on both sides of the upper end of the first conductive plate, and insertion holes opened on the front side of each insulating shell. A first copper block is provided at the bottom of each insulating shell, and a first conductive bolt is provided between the bottom sides of the first conductive plate and the first copper block. A screw is rotatably connected to the rear side of the bottom of each insulating shell. Limiting rods are fixedly connected to both sides of the screws inside the insulating shell. A pressing assembly is provided above the first copper block inside the insulating shell. The pressing assembly includes a connecting plate, with insulating blocks fixedly connected to both sides of the front end of the connecting plate, and a second copper block fixedly connected to the front end of the insulating block.
[0006] Furthermore, a groove is provided at the upper end of the first copper block, and several anti-slip strips are fixedly connected to the bottom end of the second copper block.
[0007] Furthermore, the middle position of the connecting plate is threadedly connected to the screw, and both ends of the connecting plate are slidably connected to the corresponding limiting rods.
[0008] Furthermore, an insulating top cover is fixedly connected to the upper end of the insulating housing, and an adjustment knob is fixedly connected to the upper end of the screw through the insulating top cover.
[0009] Furthermore, a spring is fitted on the outer side of the screw below the connecting plate, and a connecting ring is fixedly connected to the upper end of the spring.
[0010] Furthermore, a second conductive plate is provided on the upper left side of the first conductive plate, and a second conductive bolt is provided between the second conductive plate and the first conductive plate. A resistor is fixedly connected to the right side of the second conductive plate, a trigger component is fixedly connected to the right end of the resistor, a contact is fixedly connected to the right end of the trigger component, a conductive post is provided to the right side of the contact, and a grounding bar is fixedly connected to the rear end of the conductive post.
[0011] The beneficial effects of this utility model are:
[0012] In use, this utility model's terminal block guiding structure connects to the first copper blocks inside the insulating housings on both sides via a first conductive plate and a first conductive bolt. A wire is inserted into the insertion hole, positioned between the first and second copper blocks. Rotating the adjustment knob rotates the screw, causing the second copper block to slide along the limiting rod via the connecting plate, adjusting the distance between the first and second copper blocks. The first and second copper blocks clamp the wire. A spring is compressed when the connecting plate descends, lifting the connecting plate and increasing the friction between the screw and the connecting plate, thus preventing the connecting plate from loosening.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1-5 As shown, a terminal block current guiding structure is disclosed, comprising a first conductive plate 1, an insulating shell 2 on both sides of the upper end of the first conductive plate 1, a wire insertion hole 3 on the front side of the insulating shell 2, a first copper block 13 on the bottom of the insulating shell 2, a first conductive bolt 12 between the bottom sides of the first conductive plate 1 and the first copper block 13, a screw 15 rotatably connected to the rear side of the bottom of the insulating shell 2, a limit rod 16 fixedly connected to both sides of the screw 15 inside the insulating shell 2, and a pressing assembly 17 above the first copper block 13 inside the insulating shell 2. The pressing assembly 17 includes a connecting plate 21, an insulating block 22 fixedly connected to both sides of the front end of the connecting plate 21, and a second copper block 23 fixedly connected to the front end of the insulating block 22.
[0023] As shown in the figure, the upper end of the first copper block 13 has a groove 14, and the bottom end of the second copper block 23 is fixedly connected with several anti-slip strips 24. The middle position of the connecting plate 21 is threadedly connected to the screw 15, and the two ends of the connecting plate 21 are slidably connected to the corresponding limiting rods 16. The upper end of the insulating shell 2 is fixedly connected with an insulating top cover 4, and the upper end of the screw 15 passes through the insulating top cover 4 and is fixedly connected with an adjustment knob 18. The adjustment knob 18 is made of insulating material. Rotating the adjustment knob 18 can drive the screw 15 to rotate, thereby driving the second copper block 23 to slide along the limiting rods 16 through the connecting plate 21, adjusting the distance between the first copper block 13 and the second copper block 23. The wire can be clamped by the first copper block 13 and the second copper block 23.
[0024] As shown in the figure, a spring 19 is sleeved on the outside of the screw 15 below the connecting plate 21. A connecting ring 20 is fixedly connected to the upper end of the spring 19. The spring 19 is compressed when the connecting plate 21 descends, which can lift the connecting plate 21 and increase the friction between the screw 15 and the connecting plate 21, thereby preventing the connecting plate 21 from loosening.
[0025] As shown in the figure, a second conductive plate 5 is provided on the upper left side of the first conductive plate 1. A second conductive bolt 6 is provided between the second conductive plate 5 and the first conductive plate 1. A resistor 7 is fixedly connected to the right side of the second conductive plate 5. A trigger assembly 8 is fixedly connected to the right end of the resistor 7. The trigger assembly 8 consists of two sliding cylinders with a nickel-chromium alloy wire between them. When the nickel-chromium alloy wire is energized, it will contract. The contraction of the trigger assembly 8 can drive the contact 9 to disengage from the terminal block, thus cutting off the power. This allows the two cylinders to slide relative to each other. A contact 9 is fixedly connected to the right end of the trigger assembly 8. A conductive post 10 is provided to the right of the contact 9. A grounding bar 11 is fixedly connected to the rear end of the conductive post 10. When a fault occurs at the terminal outlet, no current flows through the first conductive plate 1. The current flows through the second conductive plate 5, resistor 7, trigger assembly 8, contact 9, and conductive post 10 into the grounding bar 11.
[0026] Working principle: In use, the first conductive plate 1 and the first conductive bolt 12 connect the first copper block 13 inside the insulating housing 2 on both sides. The wire is inserted into the insertion hole 3 and positioned between the first copper block 13 and the second copper block 23. The wire is also inserted into the groove 14, which limits the wire. Rotating the adjustment knob 18 can drive the screw 15 to rotate, thereby driving the second copper block 23 to slide along the limiting rod 16 through the connecting plate 21. The distance between the first copper block 13 and the second copper block 23 can be adjusted. The first copper block 13 and the second copper block 23 can clamp the wire. The anti-slip strip 24 can play an anti-slip role. The spring 19 is compressed when the connecting plate 21 is lowered, which can lift the connecting plate 21 and increase the friction between the screw 15 and the connecting plate 21, thereby preventing the connecting plate 21 from loosening.
