Description

Technical Field

[0001] This utility model relates to a terminal block, and more particularly to a terminal block with a locking switch. The sliding locking switch can slide between an unlocked position and a locked position. When it slides to the locked position, the locking switch presses down on the wrench on the terminal block, preventing the wrench from being opened and thus preventing the wire from being pulled out. Background Technology

[0002] Terminal blocks are an indispensable key component in electrical engineering. Their core function is to efficiently connect wires or electrical equipment, thereby ensuring stable connection and precise disconnection of circuits.

[0003] Taking the terminal block disclosed in CN214898907U as an example, it includes an insulating housing, a conductive component, and a toggle switch. The conductive component consists of a fixed conductive plate and a rotating conductive plate. The toggle switch precisely controls the rotation of the rotating conductive plate. When the toggle switch is pressed down, the rotating conductive plate and the fixed conductive plate engage tightly, firmly clamping the wire and ensuring reliable circuit continuity. When the toggle switch is lifted, the wire can be easily pulled out, allowing for convenient circuit disconnection.

[0004] However, in practical applications, especially in vibrating environments such as vehicle electrical systems, continuous vibration can cause switches to be accidentally flipped. Furthermore, during equipment installation, commissioning, or routine maintenance, engineers may accidentally touch the switches due to carelessness. These accidents can lead to unexpected circuit breaks, causing electrical equipment malfunctions, affecting the normal operation of the entire system, and even posing safety hazards. Therefore, research on the stability and reliability of terminal blocks in special environments is of significant practical importance. Utility Model Content

[0065] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0066] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0067] A terminal block 100 with a locking switch includes a housing 10, a conductive component 20, and at least one control handle 30. The housing is the external protective structure of the terminal block and is typically made of insulating material to ensure electrical isolation and physical protection. It is designed with multiple interfaces for accommodating the conductive component 20 and the control handle 30. The conductive component 20 is located inside the housing 10. The control handle 30 is pivotally connected to a first end face s of the housing 10.

[0068] The control handle is the user-operated part, used to control the connection and disconnection of the conductive component and the wire. Specifically, the control handle 30 can switch between a pressed-down state and a raised-up state; in the pressed-down state, the conductive component 20 is connected to the wire f, and in the raised-up state, the conductive component 20 is released from the wire f.

[0069] It is important to note that the housing 10 of the terminal block is equipped with a locking switch 40 that can move on the first end face s at a first position p1 and a second position p2.

[0070] When the locking switch 40 is in the first position p1, it presses against the control handle 30, which is in a depressed state. At this time, the control handle 30 cannot be freely rotated upwards under the pressure of the locking switch 40, that is, it is in a locked state.

[0071] When the locking switch 40 moves from the first position p1 on the first end face s to the second position p2, the control handle 30 can be manually lifted. At this time, the locking switch 40 is separated from the control handle 30, so that the control handle 30 can be flipped up and down, that is, it is in the unlocked state.

[0072] The aforementioned locking mechanism can prevent the control handle from being lifted due to accidental touch or vibration, thus avoiding accidental disconnection and reducing safety risks.

[0073] More specifically, the housing 10 consists of two main sidewalls, namely the first sidewall 11 and the second sidewall 12, which together form the side structure of the housing. These two sidewalls not only provide necessary mechanical support but also protect the internal conductive components 20 and the control handle 30. The locking switch 40 is cleverly designed, spanning and mounted between the first sidewall 11 and the second sidewall 12. This arrangement allows the locking switch 40 to move freely between the two sidewalls while maintaining a secure connection with the housing.

[0074] Furthermore, the two ends of the locking switch 40 are movably connected to the first sidewall 11 and the second sidewall 12 via a specific sliding structure. This sliding structure preferably includes one or more of the following techniques: rollers, sliders, or guide rail assemblies. These techniques ensure that the locking switch 40 can slide smoothly and stably along a horizontal straight path on the first end face s. This not only improves the operational flexibility of the locking switch but also ensures its reliability and durability during long-term use.

[0075] Preferably, in order to achieve precise sliding movement, the sliding structure of the locking switch 40 may also include a limiting device, which can prevent the locking switch from moving in areas other than extreme positions, thereby ensuring the safety and accuracy of operation.

[0076] It should be noted that the aforementioned technical means, together with the housing 10 and the locking switch 40, constitute a wiring and opening / closing system that is both robust and flexible. This allows the wiring terminals to ensure electrical connection stability while also facilitating circuit adjustment and maintenance.

[0077] For specific sliding components and limiting structures, the present invention preferably provides the following: the upper outer sides of the first sidewall 11 and the second sidewall 12 are respectively equipped with a first sliding groove 13 and a second sliding groove 14. These sliding grooves not only provide a stable sliding path for the locking switch 40, but also ensure its accurate positioning during movement.

[0078] The locking switch 40 includes a plate body 43, a first end 41 and a second end 42. The inner side of the first end 41 is provided with a first protrusion v1, and the inner side of the second end 42 is designed with a second protrusion v2. These protrusions match the first slide groove 13 and the second slide groove 14, allowing the locking switch 40 to slide smoothly in the slide groove while maintaining precise alignment.

[0079] To ensure the stability and accuracy of the locking switch 40 during operation, positioning protrusions r are respectively provided on the first slide 13 and the second slide 14. These positioning protrusions r provide precise positioning when the locking switch 40 moves to the first position p1. Through this technique, the locking switch 40 can be stably positioned at the first position p1, preventing maloperation due to vibration or accidental contact, thereby improving the safety and reliability of the entire terminal block.

[0080] Preferably, the first end face s in this technical solution includes a movable surface s1 and a fixed surface s2. The control handle 30 is axially connected to the movable surface s1 of the first end face s. The distribution direction of the flipping arm 31 of the control handle 30 is the length direction of the first end face s. The locking switch 40 is a locking block distributed along the width direction of the first end face s. The locking block includes a plate body 43, a first end 41 and a second end 42.

[0081] The active surface s1 is the area on the first end face s used for interaction with the control handle 30. The control handle 30 is axially connected to this area, allowing the user to connect or disconnect the conductive component 20 from the wire f by operating the control handle 30.

[0082] The fixed surface s2 is the area on the first end face s used to indicate that the locking switch 40 is in the unlocked position. When the locking switch 40 moves to this area, the control handle 30 can be freely rotated, indicating that the system is in the unlocked state.

[0083] The locking switch 40 is distributed along the width direction of the first end face s, and its main body 43, first end 41 and second end 42 together constitute a locking block. This locking block can move between the movable surface s1 and the fixed surface s2 to achieve the function of locking and unlocking.

[0084] In the locked state, the clamping wall a2 of the locking switch 40 presses tightly against the flip arm 31 of the control handle 30. At this time, the locking switch 40 is located on the movable surface s1, ensuring that the control handle 30 remains in the pressed state, thereby maintaining the connection between the conductive component 20 and the wire f.

[0085] In the unlocked state, the board body 43 moves onto the fixed surface s2, at which time the control handle 30 can be freely flipped up and down, allowing the user to perform circuit adjustments or maintenance operations.

[0086] The distinction between the movable surface s1 and the fixed surface s2 allows users to determine the locking status of the control handle 30 by observing the position of the locking switch 40, improving the intuitiveness and convenience of operation. This area division technique takes into account the user's operating habits and visual recognition, allowing them to determine the device status through simple observation, reducing the possibility of misoperation and improving the user experience.

[0087] The key advantage of this preferred technique is that by arranging the locking switch 40 and control handle 30 along the width and length directions respectively, space is optimized. This layout allows two key components to coexist on the same end face and work together to achieve locking and unlocking functions. This reduces the overall size and makes the wiring terminals more compact. Moreover, the locking switch 40 moves along the width direction, providing a simple and direct way to control the locking and unlocking state of the control handle 30. Furthermore, this layout helps improve the stability of the product when each function is implemented—the different distribution directions of the locking switch 40 and control handle 30 disperse the points of force application and application when each function is implemented.

[0088] More specifically, the locking block includes a pushing wall a1 located on the upper side and a pressing wall a2 located on the lower side. The pushing wall a1 has two ends, namely the first end 41 and the second end 42 mentioned above. The inner side of the first end 41 is provided with a first protrusion v1 that engages with the first sliding groove 13, and the inner side of the second end 42 is provided with a second protrusion v2 that engages with the second sliding groove 14.

[0089] The arrangement of the push wall a1 and the clamping wall a2 allows the locking block to precisely control the clamping and releasing of the locking switch. The push wall a1 is responsible for moving the locking block, while the clamping wall a2 is responsible for pressing the control handle firmly in the locked state, ensuring a stable locking effect.

[0090] The locking crossbar design integrates all key components into a compact structure, reducing space occupation and making the entire terminal block more compact, facilitating installation and use. Furthermore, this technology ensures the accuracy and consistency of each locking action.

[0091] Preferably, in the locked state, the upper surface of the rotating arm 31 of the control handle 30 is at the same level as the fixed surface s2; there is a flat contact between the control handle 30 and the fixed surface s2, which makes it easy for the locking switch 40 to slide horizontally and press the control handle 30 tightly.

[0092] The bottom surface of the pushing wall a1 has two inwardly inclined connecting walls a3 extending downwards from both sides, and the pressing wall a2 is connected between the two connecting walls a3. The connecting walls a3 increase the stability of the structure. In the unlocked state, the pushing wall a1 is located in the fixed surface s2 area, and the control handle 30 can be freely flipped up and down.

[0093] The first sidewall 11 and the second sidewall 12 are a distance above the first end face s. A deep opening and closing space g is formed between the first end face s, the inner surface of the first sidewall 11, and the inner surface of the second sidewall 12. The opening and closing space g provides an independent operating space for the clamping wall a2, so that the clamping and unlocking process of the clamping wall a2 and the control handle 30 can be completed in a protected environment, reducing external interference.

[0094] Furthermore, due to the presence of the opening and closing space g, the movement and positioning of the pressing wall a2 are more precise because it is confined within a space with a defined depth, which helps to improve the accuracy of pressing and unlocking the control handle 30.

[0095] Preferably, when the control handle 30 is lifted, its distal end is intentionally set to exceed the height of the first sidewall 11 and the second sidewall 12, so that when the user operates the rotating arm 31 of the control handle 30, his hand can easily reach over the sidewall and directly operate the rotating arm without being obstructed by the sidewall.

[0096] The locking switch 40 is positioned horizontally in the left-right direction of the opening and closing space g, and can move straight along the front-back direction of the opening and closing space g.

[0097] It should also be noted that, in another preferred embodiment, the locking switch 40 includes an upper top wall and a lower locking block; the top wall is a distance away from the first end face s. In this case, the top wall of the locking switch 40 can be in a fixed state, and the locking block is located below the top wall and can slide left and right along the top wall, or the locking block can be flipped downward or retracted upward relative to the top wall to achieve locking or unlocking of the control handle 30.

[0098] When locked, at least a portion of the locking block is in close contact with the upper wall of the rotating arm 31 of the control handle 30; when unlocked, the locking block moves away from the upper wall of the rotating arm 31 of the control handle 30.

[0099] The top wall extends along the length direction of the first end face, and the front-to-back length of the top wall is equivalent to the length of the first end face; or the front-to-back length of the top wall is only 1 / 5 to 1 / 3 of the front-to-back length of the first end face.

[0100] Correspondingly, in the case of sliding opening and closing, the front and rear length of the locking block can be shorter than the length of the top wall, or it can be equivalent to the length of the top wall; as long as the bottom wall of the locking block can stably and fully press the rotating arm 31.

[0101] When flipping to unlock or lock, the locking block can be flipped downwards to press the rotating arm 31 tightly.

[0102] Preferably, the locking block is a structure consisting of the connecting wall a3 and the pressing wall a2 mentioned above. The top wall is preferably the pushing wall a1, which is slidably connected to the side wall. The specific technical means have been described above and will not be repeated here.
