Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and more specifically, to a modular combined terminal block. Background Technology

[0002] Terminal blocks are used to connect various electrical equipment and cables to realize the transmission and distribution of power. Adaptive and efficient terminal blocks can improve the reliability and stability of power systems and reduce the probability of failure. A large number of cables need to be connected through terminal blocks, and efficient and reliable terminal blocks are crucial to ensuring the normal operation of power systems.

[0003] The waterproof terminals in the prior art may have their waterproof isolation materials aged, loosened, or damaged over time. Furthermore, the materials used may develop gaps, breakage, or fail to isolate water due to moisture, dryness, high temperature, friction, etc., leading to leakage and injury.

[0004] A search revealed that Chinese patent CN220652430U discloses a terminal block structure. When the input and output terminals conduct voltage and current to the outside through water, the water becomes energized. The energized water interacts with the neutral wire metal component used to surround the terminals. The neutral wire metal component absorbs and captures the current and voltage in the water, keeping the current and voltage in the surrounding water within safe limits, thus shielding against leakage caused by immersion of the power input terminals in water.

[0005] However, in actual use, when the circuit design changes, the entire terminal block needs to be replaced, which increases cost and workload. It is difficult to adapt to different electrical system requirements, and since they are all single-pole modules, it is difficult to combine them with other modules to achieve more complex electrical connection functions. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a modular combined terminal block to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A modular combined terminal block includes an outer frame, the cross-section of which is U-shaped, and an assembly mechanism is provided inside the outer frame;

[0009] The combined mechanism includes multiple connecting grooves formed on the inner wall of the outer frame. T-shaped connecting blocks are engaged inside each of the multiple connecting grooves. A single-pole fixing frame is fixedly installed at the bottom of three of the T-shaped connecting blocks, and a double-pole fixing frame is fixedly installed at the bottom of the other two T-shaped connecting blocks. Multiple limiting grooves are formed on the surface of the outer frame. U-shaped limiting frames are engaged inside each of the multiple limiting grooves. Slider blocks are provided on both sides of the U-shaped limiting frames. Multiple sliding frames are provided on both sides of the outer frame. The sliders are engaged with the sliding frames. A bolt is threaded to the top of the sliding frame. One end of the bolt passes through the sliding frame and extends into the sliding frame.

[0010] By adopting the above technical solutions, it is possible to flexibly combine different modules according to different needs. Each module has a specific function, and appropriate modules can be selected and spliced ​​according to the actual circuit design, thereby improving its versatility and applicability.

[0011] As a further description of the above technical solution: the bottom of the single pole fixing frame is provided with a connecting mechanism, the connecting mechanism includes a first terminal seat fixedly disposed at the bottom of the single pole fixing frame, a first conductive sheet fixedly disposed inside the first terminal seat, a screw groove is opened on the surface of the first conductive sheet, a screw is threadedly connected inside the screw groove, and a baffle is rotatably disposed outside the screw.

[0012] By adopting the above technical solution, different rated current and voltage levels can be selected as needed, while ensuring a firm and reliable connection.

[0013] As a further description of the above technical solution: two second terminal blocks are fixedly provided at the bottom of the bipolar fixing frame, and a second conductive sheet is fixedly provided inside each of the two second terminal blocks. A spring clip is fixedly provided inside the bipolar fixing frame, and a metal clip is fixedly provided at the bottom of the spring clip. Guide strips are fixedly provided at the bottom of the first terminal block and the second conductive sheet. A guide groove is provided on the surface of the outer frame, and the guide strip is slidably connected to the guide groove.

[0014] By adopting the above technical solution, two independent connection ports are used to connect two wires respectively, which can achieve quick connection and disconnection, making maintenance and replacement convenient.

[0015] As a further description of the above technical solution: a fixing groove is provided on the surface of the outer frame, a fixing frame is slidably connected inside the fixing groove, a threaded groove is provided on the surface of the fixing frame, a threaded rod is fixedly installed inside the threaded groove, a plurality of threaded holes are provided on the surface of the outer frame, the threaded rod is threadedly connected to the threaded holes, and a base plate is fixedly installed at the bottom of the outer frame.

[0016] By adopting the above technical solutions, the overall stability is enhanced, and it can be quickly disassembled and installed, facilitating maintenance and replacement.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. By setting up a combination mechanism, compared with the existing technology, by rotating the bolt in the forward direction, the bolt is taken out from the inside of the slide frame. Then, the U-shaped limiting frame is pulled outward, thereby moving the sliders on both sides of the U-shaped limiting frame out of the slide frame and taking the U-shaped limiting frame out of the limiting groove. Then, the U-shaped limiting frame is removed, and then the T-shaped connecting block is pulled outward, taking the T-shaped connecting block out of the connecting groove. This allows for the installation of single-pole or double-pole fixed frames in different positions, which can be freely combined. The installation process is simple and quick, without the need for complicated wiring and fixing operations, which greatly saves installation time. Moreover, during maintenance and repair, only the problematic module needs to be replaced or repaired without affecting the operation of the entire wiring system, thus reducing maintenance costs.

[0019] 2. By setting up a connection mechanism, compared with the existing technology, it can be used to connect a single wire. When the wire is accurately inserted along the first terminal block to the top of the first conductive plate, the screw is then rotated, causing the baffle to gradually approach and contact the wire. The baffle and the first conductive plate are in close contact with the wire, thereby achieving an electrical connection. Alternatively, it can be used to connect two wires. The exposed part of the wire is inserted between the second conductive plate and the metal clip. At this time, the wire will exert a squeezing force on the metal clip, thereby firmly clamping the wire between the second conductive plate and the metal clip, achieving an electrical connection. This makes the wiring process faster and more efficient, and facilitates maintenance and replacement. Different rated current and voltage levels can be selected as needed.

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The embodiments disclosed in this application are as follows: Figure 1-5 The modular combined terminal block shown includes an outer frame 1, the cross-section of which is U-shaped, and a combination mechanism is provided inside the outer frame 1.

[0028] The assembly mechanism includes multiple connecting slots 2 formed on the inner wall of the outer frame 1. T-shaped connecting blocks 3 are engaged inside each of the connecting slots 2. A single-pole fixing frame 4 is fixedly installed at the bottom of three of the T-shaped connecting blocks 3, and a double-pole fixing frame 5 is fixedly installed at the bottom of the other two T-shaped connecting blocks 3. Multiple limiting slots are formed on the surface of the outer frame 1. U-shaped limiting frames 6 are engaged inside each of the limiting slots. Slider blocks 7 are provided on both sides of the U-shaped limiting frames 6. Multiple sliding frames 8 are provided on both sides of the outer frame 1. The sliders 7 engage with the sliding frames 8. Bolts 9 are threadedly connected to the top of the sliding frames 8, with one end of the bolt 9 penetrating through the sliding frame 8 and extending into it. When reassembly or... When replacing the module, first rotate the bolt 9 clockwise to remove it from the inside of the slide frame 8. Then, pull the U-shaped limiting frame 6 outwards, thereby moving the sliders 7 on both sides of the U-shaped limiting frame 6 out of the slide frame 8 and removing the U-shaped limiting frame 6 from the limiting groove. Next, remove the U-shaped limiting frame 6 and then pull the T-shaped connecting block 3 outwards to remove it from the connecting groove 2. This allows for easy and quick disassembly and replacement, eliminating the need for complex wiring and fixing operations, thus greatly saving installation time. Moreover, during maintenance and repair, only the problematic module needs to be replaced or repaired without affecting the operation of the entire wiring system, reducing maintenance costs.

[0029] Reference Figure 2-3As shown, a connecting mechanism is provided at the bottom of the single-pole fixing frame 4. The connecting mechanism includes a first terminal block 10 fixedly disposed at the bottom of the single-pole fixing frame 4. A first conductive sheet 11 is fixedly disposed inside the first terminal block 10. A screw groove 12 is opened on the surface of the first conductive sheet 11. A screw 13 is threadedly connected inside the screw groove 12. A baffle 14 is rotatably disposed outside the screw 13. The wire is accurately inserted into the top of the first conductive sheet 11 along the first terminal block 10. Then, the screw 13 is rotated so that it gradually screws in along the thread direction of 12. As the screw 13 continues to screw in, it drives the baffle 14 to gradually approach and contact the wire. When the screw 13 continues to screw in, it will generate pressure on the wire. This pressure will cause the baffle 14 to clamp the wire. Since the baffle 14 and the first conductive sheet 11 are in close contact with the wire, an electrical connection is achieved. At the same time, the tightening force of the screw 13 can ensure the stability and reliability of this connection and facilitate correct connection.

[0030] Reference Figure 2-4 As shown, two second terminal blocks 15 are fixedly installed at the bottom of the bipolar fixing frame 5. A second conductive sheet 16 is fixedly installed inside each of the two second terminal blocks 15. A spring clip 17 is fixedly installed inside the bipolar fixing frame 5. A metal clip 18 is fixedly installed at the bottom of the spring clip 17. Guide strips 19 are fixedly installed at the bottom of both the first terminal block 10 and the second conductive sheet 16. A guide groove is formed on the surface of the outer frame 1. The guide strip 19 is slidably connected to the guide groove. The spring clip 17 is in a slightly compressed state. Moving the metal clip 18 upward causes the spring clip 17 to be squeezed and deformed, so that the second conductive sheet 16 and the metal clip 18 do not contact each other, and are in a semi-open position, providing space for the insertion of the wire. Then... When the exposed portion of the wire is inserted between the second conductive plate 16 and the metal clip 18, the wire exerts a squeezing force on the metal clip 18, causing the metal clip 18 to move inward against part of the elastic force of the spring clip 17. The spring clip 17 is further compressed, storing elastic potential energy. When the wire is fully inserted into the designated position, the elastic force of the spring clip 17 acts on the metal clip 18, causing the metal clip 18 to press tightly against the surface of the wire, thereby firmly clamping the wire between the second conductive plate 16 and the metal clip 18. Through the continuous pressure of the spring clip 17, an electrical connection is achieved, making the wiring process faster and more efficient, convenient for maintenance and replacement, and allowing for the selection of different rated current and voltage levels as needed.

[0031] Reference Figure 4-5As shown, a fixing groove 20 is provided on the surface of the outer frame 1, and a fixing frame 21 is slidably connected inside the fixing groove 20. A threaded groove is provided on the surface of the fixing frame 21, and a threaded rod 22 is fixedly installed inside the threaded groove. Multiple threaded holes 23 are provided on the surface of the outer frame 1, and the threaded rod 22 is threadedly connected to the threaded holes 23. A base plate 24 is fixedly installed at the bottom of the outer frame 1. Rotating the threaded rod 22 in the forward direction causes it to be removed from the inside of the threaded hole 23. Then, the fixing frame 21 is moved to move inside the fixing groove 20, thereby moving the fixing groove 20 to contact the surface of the single-pole fixing frame 4. Then, the threaded rod 22 is rotated in the reverse direction to enter the inside of the threaded hole 23 and the threaded groove for fixing, thereby enhancing stability. The installation process is simple and quick.

[0032] Working principle of this utility model:

[0033] This utility model relates to a modular, combined terminal block. When using this device...

[0034] When used to connect a single wire, the wire is accurately inserted into the top of the first conductive plate 11 along the first terminal block 10. Then, the screw 13 is rotated so that it is gradually screwed in along the thread direction of 12. As the screw 13 is continuously screwed in, it drives the baffle 14 to gradually approach and contact the wire. When the screw 13 continues to screw in, it will exert pressure on the wire. This pressure will cause the baffle 14 to clamp the wire. Since the baffle 14 and the first conductive plate 11 are in close contact with the wire, an electrical connection is achieved. At the same time, the tightening force of the screw 13 can ensure the stability and reliability of this connection and facilitate correct connection.

[0035] When used to connect two wires, the spring clip 17 is in a slightly compressed state. The upward movement of the metal clip 18 causes the spring clip 17 to be squeezed and deformed, so that the second conductive piece 16 and the metal clip 18 are not in contact and are in a semi-open position, providing space for the insertion of the wire. Then, the exposed part of the wire is inserted between the second conductive piece 16 and the metal clip 18. At this time, the wire will exert a squeezing force on the metal clip 18, causing the metal clip 18 to overcome part of the elastic force of the spring clip 17 and move inward. The spring clip 17 is further compressed, storing elastic potential energy. When the wire is fully inserted into the designated position, the elastic force of the spring clip 17 will act on the metal clip 18, making the metal clip 18 press tightly against the surface of the wire, thereby firmly clamping the wire between the second conductive piece 16 and the metal clip 18. Through the continuous pressure of the spring clip 17, the electrical connection is achieved, making the wiring process faster and more efficient, convenient for maintenance and replacement, and allowing for the selection of different rated current and voltage levels as needed.

[0036] When reassembly or replacement is required, first rotate bolt 9 clockwise to remove it from the slide frame 8. Then, pull the U-shaped limiting frame 6 outwards, causing the sliders 7 on both sides of the U-shaped limiting frame 6 to move out of the slide frame 8 and remove the U-shaped limiting frame 6 from the limiting groove. Next, remove the U-shaped limiting frame 6 and then pull the T-shaped connecting block 3 outwards to remove it from the connecting groove 2. Disassembly and replacement can then be performed quickly and easily. After installation, rotate the threaded rod 22 clockwise to remove it from the threaded groove. The inside of the hole 23 is removed, and then the moving fixed frame 21 is moved inside the fixed groove 20, thereby moving the fixed groove 20 to contact the surface of the single-pole fixed frame 4. Then, the threaded rod 22 is rotated in the opposite direction to enter the threaded hole 23 and the threaded groove for fixation, thereby enhancing stability. The installation process is simple and quick, without the need for complicated wiring and fixing operations, which greatly saves installation time. Moreover, during maintenance and repair, only the problematic module needs to be replaced or repaired without affecting the operation of the entire wiring system, thus reducing maintenance costs.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
