Description

Technical Field

[0001] This application relates to the technical field of connectors, and in particular to a terminal block with a two-layer interface. Background Technology

[0002] In fields such as power distribution, industrial control, and building electrical systems, terminal blocks are fundamental components used to achieve reliable electrical connections between conductors. With the increasing integration of electrical equipment and the growing compactness of cabinet space, higher demands are placed on the space utilization and wiring neatness of terminal blocks.

[0003] Currently, most mainstream terminal blocks on the market adopt a single-layer interface design, meaning all connection points are located on the same horizontal plane. When multiple wires need to be connected, this can only be achieved by horizontally arranging multiple single-layer terminals, resulting in a large area occupied on the printed circuit board (PCB) or guide rail, and the wiring is prone to becoming messy. To improve space utilization, some modular terminals have emerged in existing technologies, which achieve multi-layer connections through lateral splicing or vertical stacking.

[0004] However, such solutions typically have the following drawbacks: First, they are structurally complex, often requiring additional connectors or complex insulating shell structures to achieve interlayer assembly and electrical isolation, increasing costs and assembly difficulty; second, the stability of contact resistance is challenged, as the stacked structure results in numerous and densely packed installation points, increasing the risk of failure; third, the interfaces between upper and lower layers are too close together, making them prone to interference during wiring operations, such as the impact of already connected wires on subsequent connections, or collisions and interference between wires and tools when operating at multiple locations simultaneously, affecting construction efficiency. Summary of the Invention

[0005] To improve the safety and ease of operation of terminal connections, this application provides a terminal block with two-layer interfaces.

[0006] This application provides a terminal block with two-layer interfaces, using the following technical solution: A terminal block with two interfaces includes an insulating housing assembly and a conductive structure assembly disposed therein; The insulating housing assembly includes an integrally formed first housing and a second housing, both of which are provided with conductive structural components; the first housing is taller than the second housing; the first housing and the second housing are respectively provided with a first wiring port and a second wiring port on the same side; the first wiring port is located above the second wiring port and is staggered with the second wiring port in the horizontal direction. The conductive structure assembly includes a conductive sheet, a clamping ring, and a driving member. One end of the conductive sheet extends downward from the insulating housing assembly to form a connector plug, and the other end has a horizontal portion that extends toward the inner cavity of the clamping ring. A wiring cavity for placing a wire is formed between the clamping ring and the horizontal portion of the conductive sheet. The driving member can drive the clamping ring to move toward the horizontal portion of the conductive sheet, so that the wire is clamped in the wiring cavity.

[0007] By adopting the above technical solutions, the integrated first and second housings simplify the structure, reduce costs and assembly difficulty; the first wiring port is located above the second wiring port and is horizontally staggered, avoiding mutual interference during wiring operations and improving construction efficiency; the two-layer interface design improves the space utilization of the wiring terminals and the neatness of the wiring; the conductive sheet, clamping ring and driving component work together to form a wiring cavity, which can clamp the wires to achieve a stable electrical connection and reduce the risk of unstable contact resistance.

[0008] Optionally, both the first housing and the second housing are provided with a movable groove for the clamping ring to slide up and down, the side wall of the clamping ring abuts against the movable groove, and the horizontal part of the conductive sheet and the side of the clamping ring facing the wiring cavity are provided with anti-slip teeth.

[0009] By adopting the above technical solution, the moving groove provides a sliding path for the clamping ring, enabling the clamping ring to slide stably up and down, ensuring the stability of the wire clamping operation in the wiring cavity; the mutual abutment between the side wall of the clamping ring and the moving groove further enhances the stability of the clamping ring sliding; the anti-slip teeth on the horizontal part of the conductive sheet and the side of the clamping ring facing the wiring cavity increase the friction with the wire, making the wire less prone to loosening when clamped, thus improving the reliability of the wiring.

[0010] Optionally, the driving component is a control bolt, and the clamping ring is provided with a threaded adjustment hole that mates with the control bolt. The upper ends of the first housing and the second housing are both provided with through holes for accommodating the control bolt. The shaft of the control bolt passes through the through hole and is inserted into the moving groove, and then threadedly connected to the threaded adjustment hole.

[0011] By adopting the above technical solution, the control bolt and the threaded adjustment hole on the clamping ring are engaged, which can drive the clamping ring to slide up and down in the moving groove, realizing the clamping and loosening operation of the wire, which is convenient for wiring and disconnection; by using the threaded transmission of the control bolt, the movement of the clamping ring can be precisely controlled, ensuring the stability and reliability of wire clamping.

[0012] Optionally, both the first housing and the second housing have positioning slots on their sidewalls. The lower end of the conductive sheet has a vertical portion, and a positioning block is provided on the outer side of the vertical portion. The lower surface of the positioning block abuts against the lower bottom wall of the positioning slot, and the upper surface of the horizontal portion of the conductive sheet abuts against the upper bottom wall of the positioning slot.

[0013] By adopting the above technical solution, the lower surface of the positioning block abuts against the lower bottom wall of the positioning slot, and the upper surface of the horizontal part of the conductive sheet abuts against the upper bottom wall of the positioning slot. This ensures accurate installation of the conductive sheet, guarantees that the conductive sheet is fixed in position, prevents it from shaking or shifting inside the insulating housing, improves the stability and reliability of the wiring terminal, and ensures the stability of the electrical connection.

[0014] Optionally, the horizontal portion of the conductive sheet passes through the wiring cavity and then bends upward to form a first guide portion, and the lower end of the clamping ring has a second guide portion that bends downward.

[0015] By adopting the above technical solution, the first guide part and the second guide part can guide the wires to be inserted into the wiring cavity, making it easier for the wires to be inserted into the wiring cavity and improving the convenience of wiring operations.

[0016] Optionally, the conductive structure assembly further includes a wire pressing device, which includes a wire pressing plate extending into the wiring cavity. One end of the wire pressing plate extending into the wiring cavity is bent upward to form a third guide portion. A wire pressing cavity is formed between the wire pressing plate and the bottom wall of the clamping ring. When the clamping ring moves horizontally toward the conductive sheet, the wire pressing plate can move upward accordingly. The wire pressing device further includes an elastic element that drives the wire pressing plate to move downward to press the wire, and a linkage element that drives the wire pressing plate to move toward the positioning slot and exit the wiring cavity when the wire pressing plate moves upward with the conductive sheet.

[0017] By adopting the above technical solution, a wire pressing device is set up. The wire pressing plate and the bottom wall of the clamping ring form a wire pressing cavity to further fix the wire. The third guide part facilitates the insertion of the wire into the wiring cavity. When the clamping ring moves, the wire pressing plate moves upward with it, which is convenient for replacing the wire. The elastic element can make the wire pressing plate press the wire to ensure the connection stability. The linkage element can make the wire pressing plate exit the wiring cavity when it moves upward with the conductive sheet, so as to avoid interfering with the wire clamping operation.

[0018] Optionally, there is a gap between the clamping ring and the vertical portion of the conductive sheet to form a storage cavity, and there is also a gap between the two sides of the vertical portion of the conductive sheet and the side wall of the moving groove to form a clearance groove. The linkage includes linkage rods disposed at both ends of the pressure plate. The linkage rods are inclined and slide through the clearance groove. The linkage rods are respectively disposed on both sides of the vertical portion of the conductive sheet. The linkage also includes a guide block disposed on the side wall of the linkage rod and a guide groove formed on the first housing and the second housing. The guide groove extends inclinedly upward in the direction away from the wiring cavity.

[0019] By adopting the above technical solution, the storage cavity and the clearance groove provide space for the movement of the linkage. The inclined linkage rod, in conjunction with the guide groove, enables the wire pressing plate to move towards the positioning slot and exit the wiring cavity when the clamping ring moves, ensuring smooth wiring operation and avoiding the wire pressing plate from obstructing subsequent wiring.

[0020] Optionally, the elastic element is a spring disposed in the guide groove. One side of the spring abuts against the side wall of the guide groove, and the other side abuts against the side of the guide block away from the wiring cavity. In its natural state, the spring drives the guide block to press against the side wall of the guide groove near the wiring cavity. Both the first housing and the second housing have mounting grooves with downward-facing surfaces. The mounting grooves are connected to the positioning slots. When the guide rod moves upward at an angle along the extension direction of the guide groove, its upper end can extend into the mounting groove.

[0021] By adopting the above technical solution, in a natural state, the spring can drive the guide block to press against the side wall of the guide groove near the wiring cavity, so that the pressure plate can maintain a stable position and effectively press the wire. When the guide rod moves upward along the extension direction of the guide groove, its upper end can extend into the installation groove, which can realize the function of the pressure plate moving towards the positioning slot and exiting the wiring cavity, which facilitates the installation and removal of the wire.

[0022] Optionally, the lower end of the clamping ring is bent downward toward the storage cavity to form an anti-detachment plate, and after the wire pressing plate slides out of the wiring cavity, its end face abuts against the side wall of the anti-detachment plate.

[0023] By adopting the above technical solution, the anti-detachment plate can prevent the wire clamping plate from falling down below the clamping ring after it comes out of the wiring cavity, which helps the wire clamping plate to be reinserted into the wiring cavity when the clamping ring moves down.

[0024] Optionally, the lower surface of the pressure plate is provided with anti-slip serrations.

[0025] By adopting the above technical solution, the friction between the pressure plate and the wire can be enhanced, so that the pressure plate can drive the wire to move backward when it moves backward, thereby further ensuring that the wire moves into place.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. The insulating housing assembly, consisting of a first and second housing formed in one piece, eliminates the need for additional connectors or complex structures to achieve interlayer assembly and electrical isolation, reducing costs and assembly difficulty; 2. The first wiring port is located above the second wiring port and is staggered horizontally to avoid the interfaces on the upper and lower layers being too close, reduce mutual interference during wiring operations, and improve construction efficiency; 3. By setting up a wire clamping device, it can be ensured that the wire is not prone to coming off or rotating during the upward movement, thus ensuring the connection effect.

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. Example 1

[0029] This application discloses a terminal block with a two-layer interface. (Refer to...) Figure 1 The terminal block includes an insulating housing assembly 1 and a conductive structure assembly 2. The insulating housing assembly 1 is made of insulating materials such as plastic and is used to house and protect the conductive structure assembly 2. The conductive structure is installed inside the insulating housing and is used for electrical connection.

[0030] Reference Figure 1 and Figure 2 In this embodiment, the insulating housing assembly 1 includes an integrally formed first housing 11 and a second housing 12, both of which contain conductive structural components 2. The first housing 11 is taller than the second housing 12. The first housing 11 and the second housing 12 are located on the same side, facing the second housing 12, and respectively have a first wiring port 111 and a second wiring port 121. The first wiring port 111 and the second wiring port 121 are used for inserting and connecting wires, and multiple of both can be spaced apart along the length of the insulating housing assembly 1. Simultaneously, the first wiring port 111 is located above the second wiring port 121 and is horizontally staggered with the second wiring port 121. This staggered arrangement not only improves space utilization but also avoids wiring interference caused by excessively close interfaces between upper and lower layers, improving wiring efficiency. Furthermore, the integrally formed design of the first housing 11 and the second housing 12 makes the structure more stable, reduces the use of additional connectors, and lowers costs and assembly difficulty.

[0031] Reference Figure 1 and Figure 2 The conductive structure component 2 includes a conductive sheet 3, a clamping ring 4, and a driving component 5. The clamping ring 4 can be made of a metal material with good conductivity, such as copper, and its shape can be designed according to actual needs. In this embodiment, the clamping ring 4 is formed by bending a metal plate into a ring structure. When it is installed in the first housing 11 or the second housing 12, the rectangular inner cavity formed in its center is exactly aligned with the first wiring port 111 or the second wiring port 121. The conductive sheet 3 is formed by bending a sheet of metal material. Its lower end bends downward and extends out of the conductive structure component 2. Its end can be made into a pointed shape to form a connector plug 31 for connecting to an external circuit. The other end, that is, the upper end, is bent and extends horizontally to form a horizontal part and extends towards the inner cavity of the clamping ring 4.

[0032] A wiring cavity 6 for placing wires is formed between the upper surface of the bottom plate at the lower end of the clamping ring 4 and the lower surface of the horizontal part of the conductive sheet 3. The driving member 5 can drive the clamping ring 4 to move in the direction of the horizontal part of the conductive sheet 3, that is, to move upward, so that the wire is clamped in the wiring cavity 6.

[0033] Both the first housing 11 and the second housing 12 are provided with moving grooves 112 for the clamping ring 4 to slide up and down. The two parallel outer side walls of the clamping ring 4 abut against the moving grooves 112, which ensures the stability of the clamping ring 4 during up and down movement. The lower surface of the horizontal part of the conductive sheet 3 and the upper surface of the clamping ring 4 are provided with anti-slip teeth, which can be serrated or other shapes. The anti-slip teeth can increase the friction between the wire and the conductive sheet 3 and the clamping ring 4, and improve the reliability of the wire connection.

[0034] In this embodiment, the driving component 5 may be a control bolt 51. The upper surfaces of the first housing 11 and the second housing 12 are both provided with through holes 113 for accommodating the control bolt 51. The through holes 113 are connected to the moving groove 112. The through holes 113 are preferably countersunk holes for fitting and engaging the head of the control bolt 51. The shank of the control bolt 51 can pass through the through holes 113 and extend into the moving groove 112 below.

[0035] The top plate at the upper end of the clamping ring 4 has a threaded adjustment hole that mates with the control bolt 51. The shaft of the control bolt 51 passes through the through hole 113 and is inserted into the moving groove 112, where it is threadedly connected to the threaded adjustment hole. By rotating the control bolt 51, the clamping ring 4 can move up and down along the moving groove 112, thereby clamping and releasing the wire.

[0036] In this embodiment, preferably, both the first housing 11 and the second housing 12 have positioning slots 114 on their sidewalls. The lower end of the conductive sheet 3 has a vertical portion, the lower end of which is connected to the connector 31. A positioning block 32 is provided on the side of the vertical portion facing the positioning slot 114. The lower surface of the positioning block 32 abuts against the lower bottom wall of the positioning slot 114, and the upper surface of the horizontal portion of the conductive sheet 3 abuts against the upper bottom wall of the positioning slot 114. This positioning method can ensure the accurate installation position of the conductive sheet 3, and at the same time, it can ensure that the position of the conductive sheet 3 is not affected during the up-and-down movement of the clamping ring 4, thereby improving the stability of the conductive structure component 2.

[0037] In a further preferred embodiment, the horizontal portion of the conductive sheet 3 passes through the wiring cavity 6 and then bends upward to form a first guide portion 33, while the lower end of the clamping ring 4 has a downward-bent second guide portion 41. The first guide portion 33 and the second guide portion 41 serve as guides, facilitating the insertion of the wire. The bending angles of the first guide portion 33 and the second guide portion 41 can be adjusted according to actual needs.

[0038] The implementation principle of a terminal block with two interfaces in this embodiment is as follows: The terminal block in this embodiment achieves reliable wire connection through the cooperation of the insulating housing assembly 1 and the conductive structure assembly 2. The integrally molded insulating housing assembly 1 has a stable structure, reducing cost and assembly difficulty. The staggered arrangement of the first wiring port 111 and the second wiring port 121 avoids wiring interference and improves construction efficiency. The clamping ring 4 in the conductive structure assembly 2 can effectively clamp the wire, and the anti-slip serrations increase the reliability of the wire connection. Overall, the terminal block in this embodiment has significant improvements in space utilization, wiring reliability, and construction efficiency, and has obvious advantages compared to the prior art. Example 2

[0039] The difference between this embodiment and Embodiment 1 is that the conductive structure component 2 further includes a wire pressing device 7, which further improves the convenience and stability of connecting wires.

[0040] Reference Figure 3 and Figure 4 Specifically, in this embodiment, the wire clamping device 7 includes a wire clamping plate 71 extending into the wiring cavity 6. The wire clamping plate 71 can be made of metal or supported by insulating materials such as plastic. One end of the wire clamping plate 71 extending into the wiring cavity 6 is bent upward to form a third guide portion 72. That is, the third guide portion 72 is located on the side of the wire clamping plate 71 away from the positioning slot 114, and a wire clamping cavity 73 is formed between the wire clamping plate 71 and the bottom wall of the clamping ring 4. The third guide portion 72 facilitates the insertion of the wire into the wire clamping cavity 73. When the clamping ring 4 moves horizontally toward the conductive sheet 3, that is, moves upward, the wire clamping plate 71 can move upward accordingly and always clamp the wire to prevent the wire from sliding out or shifting left or right during the movement of the clamping ring 4, which would affect the connection effect. Furthermore, the wire pressing device 7 also includes an elastic member 74 that drives the wire pressing plate 71 to move downward to press the wire, and a linkage member 75 that drives the wire pressing plate 71 to move away from the third guide portion 72 and exit the wiring cavity 6 when the wire pressing plate 71 moves upward with the conductive sheet 3.

[0041] Reference Figure 4 and Figure 5 A gap exists between the clamping ring 4 and the vertical portion of the conductive sheet 3, forming a storage cavity 13. After the pressure plate 71 exits the wiring cavity 6, it can move into the storage cavity 13. A gap is also provided between the two sides of the vertical portion of the conductive sheet 3 and the sidewall of the moving groove 112, forming a clearance groove 14. The linkage 75 includes linkage rods 751 disposed at both ends of the pressure plate 71. The linkage rods 751 are inclined rods and extend upwards towards the clearance grooves 14, passing through the two clearance grooves 14 respectively. The linkage 75 also includes guide blocks 752 disposed on the sidewall of the linkage rods 751 and guide grooves 753 opened on the first housing 11 and the second housing 12. The guide grooves 753 are opened one-to-one with the linkage rods 751 and extend upwards in an inclined direction away from the wiring cavity 6.

[0042] The elastic element 74 is a spring disposed in the guide groove 753. One side of the spring abuts against the side wall of the guide groove 753, and the other side abuts against the side of the guide block 752 away from the wiring cavity 6. In its natural state, the spring can drive the guide block 752 to press against the side wall of the guide groove 753 near the wiring cavity 6. At this time, the connecting rod 751 drives the pressure plate 71 to extend into the wiring cavity 6, and there is a certain gap between it and the bottom plate of the clamping ring 4 for the insertion of the wire. The spring is still in a compressed state at this time, thereby ensuring the pressing effect on the guide block 752 and the pressing effect on the wire. The first housing 11 and the second housing 12 both have mounting grooves 115 with downward openings on their surfaces. The mounting grooves 115 are connected to the positioning slots 114. When the guide rod moves upward along the extension direction of the guide groove 753, its upper end can extend into the mounting groove 115. Preferably, both the guide rod and the pressure plate 71 can be made of non-conductive materials such as plastic. When the wire is connected, the guide rod moves upward to the end and moves into the positioning slot 114, which can form a limit and prevent accidental contact with the conductive piece 3 that is stuck in the positioning slot 114.

[0043] Optionally, the guide block 752 can be configured as a rectangular block structure, and the guide groove 753 can be configured as a T-shaped groove. The spring is embedded in the inner side of the guide groove 753 to prevent it from coming out. At the same time, the rectangular structure of the guide block 752 can facilitate the installation of the guide block 752.

[0044] Alternatively, the lower end of the clamping ring 4 can be bent downwards towards the storage cavity 13 to form an anti-detachment plate 42. After the wire pressing plate 71 slides out of the wire pressing cavity 73 and enters the storage slot, its end face abuts against the side wall of the anti-detachment plate 42. The anti-detachment plate 42 can prevent the wire pressing plate 71 from falling below the clamping ring 4 after it has fallen out of the wiring cavity 6. This structural design allows the wire pressing plate 71 to re-enter the wiring cavity 6 under the drive of the spring when the clamping ring 4 moves downwards again, ensuring the normal operation of the wire pressing device 7.

[0045] In this embodiment, the lower surface of the wire clamping plate 71 is also provided with anti-slip serrations. The anti-slip serrations can increase the friction between the wire clamping plate 71 and the wire, further improving the reliability of the wire connection. At the same time, when the wire clamping plate 71 moves towards the storage groove, the friction of the anti-slip serrations can drive the guide to move towards the storage groove as well, thereby further ensuring that the wire is inserted and connected in place.

[0046] The implementation principle of a terminal block with two interfaces in this application embodiment is as follows: Based on embodiment 1, a wire clamping device 7 is added. When connecting wires, the wire clamping plate 71 automatically moves into the wiring cavity 6 through the elastic element 74 and clamps the inserted wire. At the same time, during the upward movement of the clamping ring 4, the wire clamping plate 71 can move upward and clamp the wire. Simultaneously, the wire clamping plate 71 moves towards the storage groove. When the clamping ring 4 moves upward to the specified height, the wire clamping plate 71 completely exits the wiring cavity 6. During this process, it can also drive the end of the wire towards the storage groove to ensure that the wire is inserted in place. After the wire is clamped, the end of the wire clamping plate 71 abuts against the side wall of the anti-detachment plate 42 to prevent the wire clamping plate 71 from moving downward. When it is necessary to remove the wire, the clamping ring 4 is controlled to move downward by the driving element 5 to release the wire. At this time, the wire clamping plate 71 can re-extend into the wiring cavity 6 under the action of the spring and return to its original state.

[0047] 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.
