Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to a terminal block. Background Technology

[0002] Terminal blocks, as key components in electrical equipment, play a vital role in circuit connections. They contain multiple metal connection points arranged in single, double, or multiple rows, equipped with screws, spring clips, or pluggable interfaces. Their core function is to ensure a secure and reliable connection between electrical devices, enabling parallel or series connections of wires.

[0003] Conventional terminal blocks have a fixed elastic element at one end and a cantilever at the other. The cantilever end engages with the conductive terminal to clamp the wire. However, connecting and disconnecting wires requires pressing the elastic element with a tool, which is inconvenient and time-consuming, affecting construction efficiency. While existing improved technologies have incorporated a rotating elastic element with an adjustment button, the inverted snap-fit ​​structure of the elastic element's locking connector and the rotating shaft are prone to wear due to frequent friction, affecting the locking and rotation of the elastic element and reducing the reliability and lifespan of the terminal block.

In the first state, the locking element is connected to the driving element and the locking end is in the unlocked position. In the second state, the locking element is separated from the driving element and the locking end moves to the clamping position.

[0010] Optionally, the locking member includes a trigger part located within the guide groove. When the trigger part is subjected to a force acting away from the opening direction of the guide groove, it drives the locking member to switch from a first state to a second state.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, a wiring terminal is provided, comprising:

[0041] The housing 1 has a guide groove 11 suitable for wire insertion, and the guide groove 11 is connected to the interior of the housing 1;

[0042] Elastic element 2 is disposed inside housing 1. One end of elastic element 2 is fixedly connected to housing 1, and the other end forms locking end 21. Locking end 21 has a clamping position and an unlocking position.

[0043] The driving component 3 is movably disposed inside the housing 1. The driving component 3 is provided with a pressing part 31, which is used to cooperate with the locking end 21. The driving component 3 is used to drive the locking end 21 to move from the clamping position to the unlocking position.

[0044] Locking member 4 is disposed inside housing 1. Locking member 4 has a first state and a second state. In the first state, locking member 4 is connected to driving member 3 and locking end 21 is in the unlocked position. In the second state, locking member 4 is separated from driving member 3 and locking end 21 moves to clamping position.

[0045] Specifically, a fluid carrier 12 is also disposed inside the housing 1. The fluid carrier 12 plays a crucial role in realizing electrical connection and ensuring connection stability. As a medium for electrical conduction between wires, it establishes a low-resistance path between different wires with good conductivity. Its contact parts with the wires can be gold-plated or silver-plated to ensure a tight and durable contact. The fluid carrier 12 is firmly fixed in the housing 1 by means of slots or screws to avoid the influence of external forces, thereby ensuring the smooth transmission of electrical energy in each circuit branch.

[0046] It is easy to understand that the housing 1 is made of insulating material. The insulating material can effectively block current and prevent it from being conducted on the surface of the housing 1, thereby reducing the risk of short circuit caused by the conductivity of the housing 1 and ensuring the safety of electrical equipment and personnel around the terminal block.

[0047] It should be noted that in this embodiment, the elastic element 2 is selected as a spring sheet. The spring sheet material typically has good elasticity and resilience. In the terminal block, it can continuously and stably provide a reliable clamping force for the connection between the wire and the fluid-carrying 12.

[0048] It should be noted that in the second state, one end of the drive component 3 is exposed outside the housing 1, making it convenient for the user to apply external force for operation. In the first state, the drive component 3 is recessed inside the housing 1. The recessed drive component 3 can prevent accidental operation caused by accidental contact, thereby improving the stability and reliability of the system.

[0049] In the second state, the drive member 3 is in the clamping position. When transitioning from the first state to the second state, the wire is inserted into the guide groove 11 of the housing 1, and the end of the wire abuts against the locking member 4 near the fluid carrier 12, causing the locking member 4 to rotate. Under the action of the lever, the other side of the locking member 4 is separated from the drive member 3. Since the drive member 3 is no longer connected to the locking member 4, under the elastic force of the elastic member 2, the locking end 21 moves away from the locking member 4, bringing the locking end 21 closer to the wire and engaging it, connecting the wire to the fluid carrier 12, and causing the locking end 21 to reset the drive member 3. This process does not require additional tools to operate the elastic member 2, simplifying the wiring process and improving wiring efficiency.

[0050] In the first state, the driving component 3 is in the unlocked position. When transitioning from the second state to the first state, an external force is applied to the driving component 3 exposed on the housing 1. Under this force, the driving component 3 moves inward into the housing 1, contacting and locking with the locking component 4. During the locking process, the driving component 3 drives the locking end 21 of the elastic component 2, causing it to overcome its original elastic force and gradually move away from the guide groove 11, while the elastic component 2 is compressed. The wire originally held by the locking end 21 of the elastic component 2 is released, facilitating the removal of the wire from the terminal block, thus enabling wire removal. By controlling the position of the locking end 21 of the elastic component 2 through the coordinated action of the driving component 3 and the locking component 4, the wire removal process becomes simple and efficient. This effectively reduces component wear caused by frequent friction in traditional wire removal methods, extends the service life of the terminal block, and improves overall practicality and reliability.

[0051] The terminal block provided in this embodiment overcomes the shortcomings of conventional terminal blocks. During wiring, the wire is inserted into the guide groove 11 and abuts against the locking member 4, automatically separating the locking member 4 from the driving member 3. The locking end 21 of the elastic member 2 engages the wire, fixing it in the housing 1. No additional tools are needed to press the elastic member 2, significantly improving wiring convenience and construction efficiency. When removing the wire, external force is applied to the driving member 3 to lock it to the locking member 4 and drive the locking end 21 away from the wire, making operation simple and convenient. Furthermore, since the inverted snap structure and pivot of the connecting member do not require frequent use of the elastic member, reliability reduction and lifespan shortening caused by friction and wear are effectively reduced, ensuring long-term stable operation of the terminal block. The overall structure is rationally designed, functionally complete, and possesses excellent practicality and reliability.

[0052] Furthermore, the locking member 4 includes a trigger part 41, which is located in the guide groove 11. When the trigger part 41 is subjected to a force that is opposite to the opening direction of the guide groove 11, it drives the locking member 4 to switch from the first state to the second state.

[0053] In a straightforward manner, by placing the trigger part 41 within the guide groove 11, the operator only needs to apply an appropriate pushing force to the wire during insertion. This causes the trigger part 41 to experience a force acting away from the opening of the guide groove 11, automatically driving the locking member 4 to switch from the first state to the second state. This completes the clamping and fixing of the wire by the locking end 21. The entire process requires no additional tools and can be completed with one hand, improving work efficiency. Simultaneously, it avoids potential misoperations due to complex operations, ensuring operator safety and wiring stability.

[0054] Furthermore, the locking member 4 also includes a first connecting hook 42, and the side of the driving member 3 is provided with a second connecting hook 32. When the locking member 4 is in the first state, the first connecting hook 42 is connected to the second connecting hook 32, and when the locking member 4 is in the second state, the first connecting hook 42 is separated from the second connecting hook 32.

[0055] It is easy to understand that the connecting hook structure is simple and reliable. During the stable connection and separation of the locking element 4 and the driving element 3, it can control the position of the locking end 21 of the elastic element 2, ensuring the accurate execution of the clamping and unlocking actions, and effectively avoiding wiring errors or poor contact caused by an unstable connection structure. Secondly, the connection and separation mechanism of the connecting hook makes the operation of the terminal block more intuitive and convenient. Operators can connect or separate the two with simple operations, thereby quickly completing the wiring or disconnection process.

[0056] Specifically, the main body of the locking member 4 extends away from the locking member 4 and bends to form the first connecting hook 42. Its material is consistent with the main body of the locking member 4, possessing sufficient strength and toughness. The second connecting hook 32 is located at a corresponding position on the side of the driving member 3, and its shape is adapted to the first connecting hook 42 to ensure that the two can be tightly connected. When it is necessary to set the terminal block to the unlocked state, the operator presses the driving member 3 to move it, causing the second connecting hook 32 to hook with the first connecting hook 42. At this time, the locking member 4 is in the first state, and the locking end 21 of the elastic member 2 remains in the unlocked position, facilitating the insertion of the wire. When the wire is inserted, the locking member 4 is displaced in the opposite direction, and the second connecting hook 32 gradually disengages from the first connecting hook 42 during the movement. At this time, the locking member 4 switches to the second state, and the locking end 21 of the elastic member 2 quickly moves to the wire clamping position under the action of elastic force to clamp the wire, completing the wiring process.

[0057] Furthermore, the locking member 4 also includes a pivot portion 43, which allows the locking member 4 to be rotatably disposed inside the housing 1. The trigger portion 41 is connected to one side of the pivot portion 43, and the first connecting hook 42 is connected to the pivot portion 43.

[0058] Specifically, a rotating shaft 13 is provided inside the housing 1, and the rotating shaft part 43 is rotatably mounted on the rotating shaft 13.

[0059] In detail, a rotating shaft 13 is provided inside the housing 1 to mount the locking member 4, providing a center of rotation for the locking member 4. This allows the locking member 4 to rotate smoothly and stably around the rotating shaft 13 when subjected to wire contact or other external forces, ensuring accurate and error-free linkage with components such as the driving member 3 and the elastic member 2. The cooperation between the rotating shaft 13 and the rotating shaft part 43 effectively restricts the degree of freedom of the locking member 4, preventing unnecessary offset or wobbling during rotation. This improves the reliability and stability of the entire terminal block's mechanical structure, ensures the continuous and effective operation of electrical connections, reduces the risk of wiring failures caused by abnormal movement of the locking member 4, and helps extend the product's service life and improve its working performance.

[0060] In an optional embodiment, an elastic bushing structure can be used to achieve the rotation of the locking member 4. An elastic bushing is provided at a corresponding position on the housing 1, and the locking member 4 is directly nested within the elastic bushing. The elastic bushing applies a rotational force to the locking member 4 in a direction away from the driving member 3. The elastic bushing can adapt to the rotational needs of the locking member 4 to a certain extent, while also using its own elasticity to provide a certain positioning and buffering effect on the locking member 4, reducing the impact of vibration or minor collisions on the rotation of the locking member 4. However, the elasticity of the elastic bushing may decrease with time and repeated use, requiring regular inspection and replacement. Considering the integrated nature of this terminal block structure and the complexity of disassembling the terminal block during actual use, the actual application scenario needs to be considered when using this elastic bushing structure as the locking member 4 to achieve the rotational action.

[0061] Furthermore, the locking member 4 also includes a push top 44, which is connected to the other side of the rotating shaft 43. When the driving member 3 moves close to the locking member 4, the bottom of the driving member 3 abuts against the push top 44 and drives the first connecting hook 42 to swing toward the driving member 3, so as to connect the first connecting hook 42 with the second connecting hook 32.

[0062] Specifically, refer to Figure 7 As shown, the trigger part 41 is located on the left side of the locking member 4, while the rotating part 43 is located on the right side of the locking member 4.

[0063] Intuitively, when the wire is inserted, the push top 44 moves and approaches the drive member 3. Specifically, as the wire is inserted, the bottom of the wire comes into contact with the trigger part 41. Since the push top 44 is connected to the rotating shaft 43, when it receives a pushing force from the wire to the trigger part 41, the push top 44 rotates around the rotating shaft 43, causing the entire locking member 4 to rotate around the rotating shaft 43. This causes the first connecting hook 42 to swing away from the drive member 3, ultimately separating the first connecting hook 42 from the second connecting hook 32 on the drive member 3.

[0064] Furthermore, the end of the driving member 3 away from the pressing part 31 is provided with a first inclined surface 38, and the push top 44 is provided with a second inclined surface 441, with the first inclined surface 38 and the second inclined surface 441 cooperating.

[0065] Intuitively, the beveled surface allows for smoother interaction between the drive component 3 and the pusher top 44, reducing frictional resistance and jamming between components. This improves operational fluency and response speed, making the clamping and unlocking operations of the terminals more efficient and faster. Secondly, the beveled structure provides guidance; even if the drive component 3 deviates from its intended direction during operation, the beveled surface guides the pusher top 44 to accurately receive and transmit power.

[0066] Furthermore, the push top 44 includes a first segment 442 and a second segment 443 at an angle to each other. The first segment 442 is connected to the other side of the rotating shaft 43 and is arranged parallel to the trigger part 41. The second segment 443 is connected to the first segment 442 and extends toward the pressing part 31. The second inclined surface 441 is provided at the end of the second segment 443 facing the pressing part 31.

[0067] Specifically, the first segment 442 is arranged parallel to the trigger part 41, which makes the force on each component more even, enhances the structural stability of the entire terminal block, reduces the risk of component displacement or deformation caused by external force, and ensures long-term reliable operation. In terms of ease of operation, the second segment 443 extends towards the pressing part 31, which facilitates cooperation with the driving component 3, improves wiring and wire taking efficiency, reduces the probability of operational errors, and enhances the user experience.

[0068] Optionally, the first segment 442 and the second segment 443 are arranged at 90° to form an L-shaped structure.

[0069] Furthermore, the driving member 3 includes a rod 33, one end of which near the opening of the guide groove 11 forms a driving end 34, and the other end of the rod 33 cooperates with the locking member 4, with a pressing part 31 formed on the rod 33.

[0070] It is easy to understand that the external operating force is applied to the rod 33 through the drive end 34, and the force is transmitted to the pressing part along the rod 33.

[0071] Furthermore, the rod body 33 is provided with a mounting groove 35, which has two opposing surfaces that pass through the rod body 33. The locking end 21 passes through the mounting groove 35. The mounting groove 35 is inclined toward the bottom of the guide groove 11, and the opening of the mounting groove 35 on the side near the guide groove 11 is located at the inclined low position. The surface of the mounting groove 35 facing the locking member 4 forms a pressing part 31.

[0072] In terms of ease of operation, the inclined mounting groove 35, with its opening near the bottom of the guide groove 11 at a lower position, allows the locking end 21 to reach the clamping position more naturally and smoothly during the clamping process, aided by gravity and the guidance of the inclined surface. This reduces the driving force required by the drive component 3, resulting in a lighter and smoother operating feel and improved wiring efficiency. From the perspective of structural stability and reliability, the inclined mounting groove 35 provides a stable movement trajectory for the locking end 21, reducing the risk of the locking end 21 deviating from its correct position due to vibration or external interference.

[0073] In an alternative embodiment, a protrusion may be provided on the rod 33 to replace the mounting slot 35. The protrusion on the rod 33 pushes the locking end 21 as the rod 33 moves. It can guide the locking end 21 to move in a predetermined direction, similar to the guiding effect of the mounting slot 35 on the locking end 21.

[0074] Furthermore, the drive unit 3 is provided with an echo cavity 36.

[0075] It is easy to understand that when the driving component 3 connects with the locking component 4, it will strike the outer wall of the echo cavity 36, producing a crisp "snap" sound. This prompt sound can intuitively provide feedback to the user on the occurrence of the operation, allowing the user to clearly know whether the wiring or unwielding operation has successfully triggered the corresponding mechanical linkage. For example, when the lighting is poor or the operating space is small and it is difficult to directly observe changes in the internal structure, the prompt sound can effectively assist the user in judging the operation progress, greatly improving the convenience and accuracy of the operation, enhancing the interactive experience between the user and the wiring terminal, making the entire operation process more efficient and smooth, and reducing misoperations or repetitive operations caused by unclear operation.

[0076] Furthermore, it also includes at least one rotation limiter 14, which is disposed inside the housing 1 and is adapted to limit the rotational stroke of the locking member 4 during state switching.

[0077] Specifically, in this embodiment, two rotation limiters 14 are provided on both sides of the locking member 4. The rotation limiters 14 can effectively prevent the locking member 4 from colliding with other components or deviating from its normal working track due to excessive rotation. For example, when the locking member 4 switches from the second state to the first state, the rotation limiters 14 can ensure that the locking member 4 rotates only to a predetermined angle, so that the driving member 3 can drive the elastic member 2 to move appropriately. This ensures the accuracy and reliability of the mechanical structure's operation and avoids damage to the internal mechanical structure caused by over-rotation of the locking member 4, thereby improving the stability and durability of the overall mechanical structure of the terminal block.

[0078] Furthermore, the drive member 3 is provided with a limiting part 37, which is adapted to engage with the housing 1 when the drive member 3 is in the clamping position.

[0079] It is easy to understand that the limiting part 37 on the drive member 3 is used to prevent the drive member 3 from detaching from the housing 1. When the drive member 3 is in the clamped position, the limiting part 37 engages with the housing 1, which physically constrains the drive member 3 and effectively prevents the drive member 3 from detaching from the housing 1 due to accidental external impact, excessive mechanical vibration or other abnormal working conditions.

[0080] Specifically, the limiting part 37 may be a protrusion structure provided on the side of the driving member 3. The shape of the protrusion structure may be rectangular, semi-circular, or trapezoidal, etc., and it is used to engage with the housing 1 to prevent the driving member 3 from detaching from the housing 1.

[0081] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
