Description

Technical Field

[0001] This utility model relates to the field of wiring structure technology, and specifically to a wiring device. Background Technology

[0002] This section provides only background information relevant to this disclosure and does not necessarily constitute prior art.

[0003] In the field of electrical wiring devices, especially in miniaturized and integrated electrical equipment, the quick tightening and loosening of cables is key to improving installation efficiency. Traditional wiring devices typically use screws for tightening, but this method is inefficient.

[0004] To address the issue of low wiring efficiency, a wiring method using spring-loaded connectors has emerged on the market. However, some spring-loaded connectors require users to continuously operate them to keep the spring-loaded terminals in the locked or loosened position. Otherwise, the spring-loaded terminals will reset under the action of elastic force, increasing the difficulty of operation. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the fact that the current wiring device requires the user to continuously operate the spring-type wiring device to keep the spring-type wire clamp terminal in the locked or loose position, which increases the difficulty of operation, thereby providing a wiring device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a wiring device, including: The housing has a cable interface and a cable clamping component inside the housing. The cable clamping component is held in a locked or loose position by a positioning component. The positioning component includes: A positioning part is provided on the wire clamping component; A positioning element is disposed on the housing. The positioning element cooperates with the positioning part to restrict the movement position of the wire clamping component, so that the wire clamping component maintains the wire-locked position or the wire-loosening position.

[0007] To further optimize the technical solution, the positioning component is provided with a first guide portion, which is an inclined structure, used to guide the positioning component to engage or disengage from the positioning portion.

[0008] To further optimize the technical solution, a reinforcing plate is provided on the housing, and the reinforcing plate is connected to the positioning component.

[0009] To further optimize the technical solution, the wiring device also includes: A limiting member is disposed at the end of the wire clamping component. The limiting member cooperates with the housing to restrict the movement stroke of the wire clamping component.

[0010] The technical solution is further optimized by providing an abutment part on the limiting member and an opening on the housing. The prying member is guided to the prying point through the opening and the abutment. The prying member applies force to the prying point, causing the wire locking component to switch between the wire locking position and the wire loosening position.

[0011] To further optimize the technical solution, a second guide portion is provided on the contact portion.

[0012] To further optimize the technical solution, the limiting member is provided with a first limiting part, and the housing is provided with a first mating part. The travel of the locking wire member into the housing is limited by the first mating part abutting against the first limiting part.

[0013] To further optimize the technical solution, the limiting member is provided with a second limiting part, and the housing is provided with a second mating part. The travel of the locking wire member moving out of the housing is limited by the second mating part abutting against the second limiting part.

[0014] To further optimize the technical solution, there is a gap between the second mating part and the wall surface of the limiting member. By pressing the limiting member toward the second mating part, the positioning member and the positioning part are disengaged.

[0015] To further optimize the technical solution, a third guide part is provided on the second mating part.

[0016] The technical solution of this utility model has the following advantages: This invention, through the cooperation of the positioning part and the positioning component in the positioning assembly, can stably maintain the wire clamping component in the locked or loosened position. The user does not need to continuously apply external force to the wiring device to maintain the current state of the wiring device, reducing the difficulty of operation. At the same time, compared with the traditional screw locking method, this device achieves rapid switching between locked / loosened states through mechanical positioning, which significantly improves wiring efficiency and is especially suitable for cable connection scenarios of miniaturized and integrated electrical equipment.

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] The specific embodiments of this utility model are described in detail below with reference to the wiring device of this utility model.

[0022] Example 1 Combination Figures 1 to 5As shown, according to an embodiment of the present invention, a wiring device is provided, including a housing 4, a cable clamping component 1, and a positioning component. The housing 4 is provided with a cable interface 43 for inserting a cable 5. The cable clamping component 1 is located inside the housing 4 and is held in either a locked or loose position by the positioning component. The loose position allows the cable 5, which is locked in the cable interface 43, to be pulled out, while the locked position secures the cable 5 inserted into the cable interface 43. Moving the cable clamping component 1 between the loose and locked positions allows for locking or unplugging of the cable 5.

[0023] The positioning assembly includes a positioning part 15 and a positioning element 2. The positioning part 15 is disposed on the cable clamping component 1. The positioning element 2 is disposed on the housing 4. The positioning element 2 cooperates with the positioning part 15 to restrict the movement position of the cable clamping component 1, so that the cable clamping component 1 maintains the cable-locked position or the cable-loosening position, which facilitates the user's operation of inserting and removing the cable 5.

[0024] The above-mentioned wiring device, through the cooperation of the positioning part 15 and the positioning member 2 in the positioning component, can stably maintain the wire clamping part 1 in the locked or loosened position. The user does not need to continuously apply external force to the wiring device to maintain the current state of the wiring device, which reduces the difficulty of operation. At the same time, compared with the traditional screw locking method, this device achieves rapid switching between locked / loosened states through mechanical positioning, which significantly improves wiring efficiency and is especially suitable for cable connection scenarios of miniaturized and integrated electrical equipment.

[0025] The positioning element 2 and the positioning part 15 engage or disengage to fix the wire-clamping component 1 in a specific position, effectively preventing accidental movement when not in operation. The user can operate the positioning part 15 to change the current engagement state between the positioning element 2 and the positioning part 15, thereby switching the position of the wire-clamping component 1 and ensuring it remains in the changed position. For example, by operating the positioning part 15, the user can change the engagement state between the positioning element 2 and the positioning part 15, thus switching the wire-clamping component 1 from the locked position to the loose position, and ensuring it remains in the loose position; conversely, by operating the positioning part 15, the user can change the disengagement state between the positioning element 2 and the positioning part 15, thus switching the wire-clamping component 1 from the loose position to the locked position, and ensuring it remains in the locked position. For example, by operating the positioning part 15, the user changes the relationship between the positioning member 2 and the positioning part 15 from a disengaged state to an engaged state, thereby enabling the wire clamping component 1 to switch from the loose wire position to the locked wire position and ensuring that the wire clamping component 1 remains in the locked wire position; by operating the positioning part 15, the user changes the relationship between the positioning member 2 and the positioning part 15 from an engaged state to a disengaged state, thereby enabling the wire clamping component 1 to switch from the locked wire position to the loose wire position and ensuring that the wire clamping component 1 remains in the loose wire position.

[0026] The wire clamping component 1 may have two positioning parts 15, which are arranged along the moving direction of the wire clamping component 1. The first positioning part is closer to the outer wall of the housing 4 than the second positioning part. When the positioning member 2 engages with the first positioning part, the wire clamping component 1 is in the wire-locked position; when the positioning member 2 engages with the second positioning part, the wire clamping component 1 is in the wire-loosening position.

[0027] The positioning element 2 and the positioning part 15 can be fitted together using a concave-convex mating method. For example, the positioning part 15 can be designed as a groove or a through hole, and the corresponding positioning element 2 can be an elastic buckle, a rib, or a slider. The locking and unlocking of the position is achieved by the elastic buckle / rib / slider engaging with the groove or through hole, or disengaging from it. When the elastic buckle / rib / slider engages with the groove or protrusion, the wire-locking component 1 is fixed in the locked or loosened position. When the wire-locking component 1 is pressed, the elastic buckle / rib / slider disengages from the groove or protrusion, thereby allowing the wire-locking component 1 to switch positions.

[0028] The positioning element 2 and the positioning part 15 can also be fitted with a groove or hole to the rod body. For example, the positioning element 2 is a positioning rod, and the positioning part 15 is a positioning hole or positioning groove provided on the wire clamping component 1. When the positioning rod is inserted into the positioning hole or positioning groove, the wire clamping component 1 is positioned in the wire locking position or the wire loosening position.

[0029] The positioning component 2 and the positioning part 15 can be engaged in a hook-like manner. For example, the positioning component 2 can be designed as a hook that bends toward the second end of the locking member 11, and the positioning part 15 can be designed as a hook that bends in the opposite direction to the positioning component 2. The positioning of the locking member is completed by the mutual hooking or separation of the two opposite hooks.

[0030] The aforementioned wiring device includes a cable clamping component 1 comprising an elastic member 12 and a cable locking member 11. The cable locking member 11 includes a first end connected to the elastic member 12 and a second end extending into a preset operating range. By applying force or mechanical energy to the second end within the preset operating range, the elastic member 12 deforms, causing the cable locking member 11 to move between a loose position and a locked position. The loose position refers to a position where the cable 5 can be pulled out, and the locked position refers to a position where the cable 5 can be locked. The movement of the cable locking member 11 between the loose and locked positions enables the cable 5 to be locked or pulled out.

[0031] It should be noted that the preset operating range refers to the range that can be operated by hand. However, in certain specific scenarios, tools such as screwdrivers can be used to assist in operation in order to achieve better operating results. For example, in scenarios where the wiring device is installed in a narrow gap or embedded mounting slot, where the space for manual operation is limited, tools such as screwdrivers can serve as a medium for transmitting force. Their slender rods can extend into the limited space to contact the second end of the locking member, and the degree of deformation of the elastic member 12 can be more precisely controlled by rotation or pushing actions to ensure that the locking member 11 is stably switched to the target position.

[0032] In this application, the second end is a free end and is not connected to any position on the elastic member 12, providing sufficient redundancy for operation. Whether the force is applied directly by hand or indirectly with the help of a tool, there will be no motion interference due to the connection between the second end and the elastic member 12.

[0033] The elastic member 12 and the locking member 11 are integrated. Their integrated molding structure allows the elastic force of the elastic member 12 to be directly and evenly transmitted to the locking member 11. When force or mechanical energy is applied to the second end (free end) of the locking member 11, the elastic member 12 can simultaneously undergo a corresponding degree of deformation, ensuring that the switching action of the locking member 11 between the loose position and the locked position is smooth and precise.

[0034] In some embodiments, the positioning member 2 is provided with a first guide portion 17, which is a sloped structure, wherein the slope of the sloped structure is such that the end closer to the loosened wire position is higher than the end farther from the loosened wire position. In this embodiment, when the locking member 11 moves to the loosened wire position, the sloped structure of the first guide portion 17 can guide the positioning member 2 to engage with the positioning part 15, avoiding jamming problems caused by alignment errors and ensuring that the positioning member 2 and the positioning part 15 engage quickly and accurately. During the process of the locking member 11 moving from the loosened wire position to the locked wire position, the first guide portion 17 can assist the positioning member 2 to smoothly disengage from the positioning part 15, reducing mechanical impact or frictional resistance at the moment of disengagement and preventing wear of the components due to forced separation.

[0035] In some embodiments, a reinforcing plate is provided on the housing 4, and the reinforcing plate is connected to the positioning member 2. For example, the reinforcing plate can be a plastic reinforcing rib or a stainless steel sheet. The reinforcing plate can enhance the structural strength of the connection between the positioning member 2 and the housing 4, prevent the positioning member 2 from deforming or loosening during long-term use or under stress, ensure the fitting accuracy and stability of the positioning member 2 and the positioning part 15, extend the service life of the device and improve its reliability.

[0036] In some embodiments, the wiring device further includes a limiting member 3, which is a block structure. The limiting member 3 is disposed at the second end of the locking member 11. The limiting member 3 cooperates with the housing 4 to limit the movement stroke of the locking member 1, avoid structural damage or positioning failure caused by excessive movement of the locking member 1, ensure stable switching of the locking member 1 between the locking and loosening positions, and improve the structural reliability and service life of the device.

[0037] The limiting member 3 can be directly formed by optimizing the structure of the second end of the locking member 11. For example, the end of the second end can be bent into a triangle or a shape with a limiting protrusion, or a limiting protrusion can be directly set within a preset operating range of the second end. Alternatively, the edge of a specific section can be designed as a structure with a limiting function, thereby naturally limiting the maximum distance that the locking member 11 can move in and out of the housing 4. The limiting member 3 can slide along with the movement of the second end, and the sliding path of the limiting member 3 forces the second end of the locking member 11 to move the maximum distance out of and / or into the housing 4.

[0038] More specifically, for the limiting member 3 set within the preset operating range, the shape of the limiting member 3 can be designed to facilitate the user's application of force, such as a flat surface with anti-slip texture, an arc-shaped protrusion, or a groove adapted for finger pressing. This design allows the limiting member 3 to not only achieve trajectory constraint and travel limitation functions, but also serve as a force application point for user operation, improving the convenience and comfort of operation, and making it easier for the user to directly operate the second end.

[0039] The limiting member 3 is provided with an abutment part 35, and the housing 4 is provided with an opening 45. The opening 45 and the abutment part 35 guide the prying member 6 to the prying force application point. The prying member 6 applies force to the prying force application point, causing the cable clamping component 1 to switch between the locked and released positions. In this embodiment, the cooperation between the opening 45 and the abutment part 35 accurately guides the prying member 6 to the force application point, avoiding positioning deviations during operation and improving the convenience and accuracy of operation. Simultaneously, the application of external force by the prying member achieves the switching of the cable clamping component's state, making operation labor-saving and efficient, ensuring that users can quickly and reliably complete the locking and releasing operations of the cable.

[0040] To further improve the positioning accuracy and smooth force application of the prying component 6, a second guide portion 33 can be added to the abutment portion 35, and a corresponding third guide portion 34 can be provided on the second mating portion 42. These two guide portions can be designed as inclined or curved surfaces that adapt to the shape of the prying component 6: the second guide portion 33 can assist the end of the prying component 6 to quickly fit with the abutment portion 35, while the third guide portion 34 can correct angular deviations during the insertion of the prying component 6. The combination of the two further reduces the difficulty of operation and ensures that the prying action is efficient and labor-saving.

[0041] In some possible implementations, the limiting member 3 is provided with a first limiting part 31, and the housing 4 is provided with a first mating part 41. By the first mating part 41 abutting against the first limiting part 31, the travel of the locking member 11 in the housing 4 is limited, so as to avoid the locking member 11 from excessively rebounding and causing insufficient opening of the clamping hole 141, which in turn causes the cable 5 to be unable to be inserted.

[0042] In some possible implementations, the limiting member 3 is provided with a second limiting part 32, and the housing 4 is provided with a second mating part 42. The travel of the locking member 11 moving out of the housing 4 is limited by the second mating part 42 abutting against the second limiting part 32.

[0043] To facilitate switching between the locked and loosened positions of the cable locking component 1, a gap is provided between the second mating part 42 and the wall surface of the second end in this embodiment. This gap provides operating space for the user to operate the second end of the cable locking component 11 and also reserves necessary clearance for the disengagement of the positioning part 15 and the positioning member 2. Since the second mating part 42 and the positioning member 2 are located on both sides of the cable locking component 11, when the user moves the limiting member 3 on the second end toward the second mating part 42, it drives the cable locking component 11 to move away from the positioning member 2, causing the positioning member 2 to separate from the positioning part 15, thereby releasing the positioning constraint on the cable locking component 11, allowing the cable locking component 1 to exit the loosened state and switch to the locked state.

[0044] In some embodiments, the limiting member 3 protrudes from the outer surface of the housing 4, facilitating direct operation of the limiting member 3 by the user, thereby facilitating the application of force (such as pressing or pushing) to the second end of the locking member 11. Furthermore, by directly applying force to the second end, the force application stroke is shorter, and the time consumed in the force transmission process is reduced, resulting in faster and more stable wiring. As an alternative embodiment, the limiting member 3 is flush with the outer surface of the housing 4, keeping the surface of the housing 4 smooth and preventing external interference or accidental contact with the limiting member 3, thus enhancing the overall reliability and durability of the device. Compared to a preset operating range located within the housing 4, there is no need to reserve space for hands or tools to enter the housing 4, reducing the volume of the housing 4 and making it suitable for scenarios with limited installation space, thus improving the product's adaptability to different scenarios.

[0045] Furthermore, the preset operating range and the cable interface 43 are located on different walls of the housing 4, and the cable 5 at the preset operating range and the cable interface 43 will not interfere with each other. For example, the preset operating range is located on the side of the housing 4, and the cable interface 43 is located on the top or bottom of the housing 4. As another example, the preset operating range is located on the top or bottom of the housing 4, and the cable interface 43 is located on the side of the housing 4.

[0046] In some embodiments, to facilitate operation of the limiting member 3, a notch 46 is provided on the housing 4. The notch 46 exposes the limiting member 3, thereby facilitating the user to press the limiting member 3. Preferably, the notch 46 and the positioning member 2 are located on the same side of the housing 4, thereby facilitating the user to press the limiting member 3 away from the positioning member 2 through the notch 46.

[0047] In some embodiments, the locking member 11 is provided with a clamping hole 141. When the elastic member 12 deforms, the opening of the clamping hole 141 changes, causing the locking member 11 to move between a locked position and a loosened position to lock or release the inserted cable 5. In this embodiment, the clamping hole 141 has a hole-like structure. After the cable is inserted, it forms circumferential contact with the hole wall. Compared with the single-point pressing of traditional screws or the partial clamping of spring clips, the contact area is larger, the clamping force is more evenly distributed, the risk of cable loosening due to vibration and pulling is reduced, and the stability of the electrical connection is improved.

[0048] More specifically, the locking member 11 is provided with a through hole 14, and the third end of the elastic member 12, which is not connected to the locking member 11, extends movably through the through hole 14 to divide the through hole 14 into a clamping hole 141 and a movable hole 142. When the locking member 11 moves, the elastic member 12 undergoes relative displacement within the movable hole 142, causing a change in the diameter of the clamping hole 141. For example, when the locking member 11 moves closer to the elastic member 12, the diameter of the clamping hole 141 decreases, and the diameter of the movable hole 142 increases to lock the inserted cable 5. When the locking member 11 moves away from the elastic member 12, the diameter of the clamping hole 141 increases, and the diameter of the movable hole 142 decreases to release the inserted cable 5.

[0049] The clamping hole 141 is formed by the through hole 14 being separated by the elastic member 12, and its edge can be a continuous hole wall structure to enhance the rigidity of the locking member 11. When the hole diameter is reduced, the elastic member and the locking member can interact to clamp the cable 5 with a clamping force. Compared with the single point or line contact of the traditional spring-type terminal, it not only has a larger contact area, but also a more stable and firm clamping.

[0050] In addition, a gap is left between the third end of the elastic member 12 and the wall of the through hole 14, which provides a stable guide for the movement of the locking member 11 and avoids friction and jamming between the two.

[0051] As an alternative embodiment, the third end does not extend through the through hole 14 but is directly fixed to the housing 4. A column is provided on the housing 4, passing through the through hole 14 and dividing it into a clamping hole 141 and a movable hole 142. For example, the circumferential surface of the column can be an arc-shaped groove, an arc-shaped convex groove, or a plane; that is, the column is a rectangular column. In this embodiment, the axial direction of the column is perpendicular to the moving direction of the locking member 11, and the column directly engages with the housing 4 via the locking member 11. During the locking and releasing of the wire, the column ensures that the third end is fixed, and only the relative displacement between the locking member 11 and the column changes the opening of the clamping hole 141.

[0052] Furthermore, a gap can be left between the post and the wall of the through hole 14, which provides a stable guide for the movement of the locking component 11 and avoids friction and jamming between the two.

[0053] In some embodiments, the wire-clamping component 1 can be fixed to the insert terminal 44 through the through hole 14. Specifically, in conjunction with Figure 1 As shown, the insert terminal 44 is provided with an assembly structure 48, which can cooperate with the through hole 14 to fix the wire clamping component 1 to the insert terminal 44. The insert terminal 44 is limited by the conformal limiting groove in the housing 4, thus fixing the wire clamping component 1 inside the housing 4. The assembly structure 48 can be a hook or a column. For example, during assembly, by squeezing the third end to move it away from the wire locking component 11, the diameter of the wire clamping hole 141 in the through hole 14 is enlarged. Then, the assembly structure 48 on the insert terminal 44 is inserted into the wire clamping hole 141 of the through hole 14. The third end is released, and under the influence of elasticity, the third end can move towards the wire locking component 11 to reduce the diameter of the wire clamping hole 141, tightly clamping the assembly structure 48 of the insert terminal 44 in the wire clamping hole 141, thereby fixing the wire clamping component 1 to the insert terminal 44. This assembly method eliminates the need to weld the wire clamping component 1 to the insert terminal 44, reducing assembly difficulty and preventing the wire clamping component 1 from being unable to be fixed in the housing 4 due to solder joint detachment during subsequent use, thus enhancing assembly reliability.

[0054] More specifically, the elastic member 12 includes a connecting section 121 and a positioning section 122. The first end of the locking member 11 is fixedly connected to one end of the connecting section 121, while the other end of the connecting section 121 is connected to one end of the positioning section 122. The other end of the positioning section 122 extends movably through the through hole 14. In this connection structure, a clamping hole 141 is formed between the outer wall of the positioning section 122 and the wall surface of the through hole 14 on the side away from the connecting section 121, allowing the cable 5 to pass through. When the clamping member 1 is installed in the housing 4, the positioning section 122 remains stationary relative to the housing 4. When no external force is applied to the second end of the locking member 11, the elastic member 12 is in its initial position due to its own elasticity. At this time, the inner wall of the through hole 14 away from the connecting section 121 is tightly fitted with the outer wall of the positioning section 122, the opening of the clamping hole 141 is at its minimum, and the opening of the movable hole 142 is at its maximum. When an external force is applied to the second end of the locking member 11, causing it to move away from the connecting section 121, since the positioning section 122 is stationary relative to the housing 4, the inner wall of the through hole 14 away from the connecting section 121 will separate from the outer wall of the positioning section 122, and the opening of the clamping hole 141 will increase until the opening of the movable hole 142 is at its minimum. Through this structure, the opening of the clamping hole 141 can be changed, thereby completing the switching of the locking member 1 between the locking position and the loosening position.

[0055] This embodiment optimizes the structural design. By controlling the movement of the locking component 11, the opening of the clamping hole 141 formed by the locking component 11 and the positioning section 122 is changed, thereby achieving locking or unlocking. The entire process requires no complicated multi-step operations or tool assistance, and a single person can easily install, adjust, and remove the cable, greatly improving operational efficiency. Furthermore, when no external force is applied to the second end of the locking component 11, the elastic component maintains its initial state by its own elasticity, minimizing the opening of the clamping hole 141. This provides a continuous and stable clamping force for subsequent cable clamping, effectively preventing the cable from accidentally loosening due to vibration, pulling, or other reasons. At the same time, the design of the positioning section being stationary relative to the housing reduces the risk of locking failure caused by structural displacement, further ensuring the stability of the locking mechanism.

[0056] The locking component 11, connecting section 121, and positioning section 122 enclose an unclosed compression ring. The wire clamping component 1 is an elastic element. When the wire clamping component 1 is in the locked position, the compression ring is in an expanded configuration; when the wire clamping component 1 is in the loose position, the compression ring is in a compressed configuration, storing elastic potential energy. When the external force on the second end is removed and the wire clamping component 1 switches from the loose position to the locked position, the compression ring expands under its own elastic force, and the opening of the clamping hole 141 decreases to clamp the cable 5. In this embodiment, instead of the traditional design that relies on independent reset components such as external component structures, rapid automatic locking is achieved through the integrated elasticity of the components, simplifying the structure, reducing the number of parts, and reducing assembly complexity and cost. When the compression ring expands, it generates a continuous inward tightening force on the locking component 11, ensuring that the inner wall of the clamping hole 141 maintains stable pressure contact with the cable 5.

[0057] In some embodiments, the limiting member 3 is provided with an insulating member. More specifically, the operable portion of the limiting member 3 is encapsulated with a plastic part, so that the wire clamping component 1 and the plastic part are injection molded into a single part. The end of the wire clamping component 1 is encapsulated with plastic to make the product safer and easier to operate. The shape of the insulating member can be completely consistent with the shape of the limiting member 3, closely fitting the contour of the limiting member 3 to achieve conformal encapsulation and maintain a compact structure; or it can be designed as an independent form according to operational needs, such as adding arc-shaped protrusions, anti-slip textures, or grooves adapted for finger pressing on the operable portion, while retaining the insulation function and further optimizing the operating feel and force application efficiency.

[0058] In some embodiments, an anti-detachment component is provided between the insulating component and the limiting component 3 to enhance the connection stability between the two, prevent the insulating component from separating from the limiting component 3 during long-term operation or vibration environment, and ensure long-term reliability of insulation function and operating feel. The specific form of the anti-detachment component can be flexibly selected according to connection requirements. It can be a mechanical interlocking structure, such as pre-setting grooves, protrusions, or barbs on the surface of the limiting component 3. When the insulating component is injection molded, the plastic material fills into these structures, forming a physical interlock, using the concave-convex fit to prevent the insulating component from falling off. It can also be a surface roughening treatment, such as roughening the surfaces of the limiting component 3 and the insulating component by drawing, sandblasting, or creating fine textures to increase the contact friction between the two, limiting the displacement of the insulating component through friction and reducing the risk of detachment. Alternatively, it can be an interlocking structure, such as providing through holes or notches on the limiting component 3, allowing the plastic material to pass through these holes or notches during injection molding to form an anchoring connection, making the insulating component and the limiting component 3 form a mutually interlocking whole, structurally eliminating the possibility of separation.

[0059] The overall working process of the above wiring device is as follows: (a) Wiring process Moving the locking member 11 to the loosened position opens the clamping hole 141, facilitating the insertion of the cable 5. Specifically, when the locking member 11 is moved away from the elastic member 12 by the limiting member 3, the diameter of the clamping hole 141 expands, and the diameter of the movable hole 142 shrinks. At this time, the compression ring is in a compressed configuration, storing elastic potential energy. When the positioning member 2 engages with the positioning part 15 on the second end, the opening of the clamping hole 141 remains unchanged. At this time, the cable interface 43 corresponds to the clamping hole 141, and the cable 5 can be inserted into the clamping hole 141 through the cable interface 43.

[0060] After the cable 5 is inserted into the clamping hole 141, the locking member 11 is moved to the locking position, causing the clamping hole 141 to shrink and clamp the cable 5. Specifically, the limiting member 3 is pressed by hand or with a tool, causing the limiting member 3 to move away from the positioning member 2, thereby disengaging the positioning part 15 on the limiting member 3 from the positioning member 2. At this time, the position of the locking member 11 is no longer restricted by the positioning member 2. The compression ring expands under its own elastic force, thereby driving the locking member 11 to move closer to the connecting section 121. As the locking member 11 moves, the opening of the clamping hole 141 gradually decreases. Finally, with the cooperation of the locking member 11 and the positioning section 122, the cable 5 is clamped, ensuring a stable and reliable cable connection.

[0061] (II) Loosening the Thread Before the cable needs to be loosened, the clamping hole 141 is in a clamped state on the cable 5. To facilitate control of opening the clamping hole 141, such as... Figure 3 As shown, insert a pry tool 6 (e.g., a flathead screwdriver) into the slot shown in the diagram, and pry outwards from the edge of the top cover of the housing 4, causing the cable clamping component 1 to move outwards, thus enlarging the diameter of the cable clamping hole 141. During this movement, the positioning part 15 of the cable clamping component 1 will re-establish a mating relationship with the positioning part 2 inside the housing. When the positioning part 15 of the cable clamping component 1 engages with the positioning part 2 on the housing, the cable clamping component 1 is positioned by the positioning part 2. At this time, the cable clamping hole 141 of the cable clamping component 1 opens to a sufficiently large opening, allowing the cable 5 to be pulled out, completing the cable loosening operation.

[0062] Example 2 Combination Figure 6 As shown, based on Embodiment 1, this embodiment provides a wiring device. The difference between this embodiment and Embodiment 1 is that the specific structure of the limiting member 3 has been changed. In this embodiment, the limiting member 3 is replaced by a hook-shaped structure instead of the block structure of Embodiment 1. The hook-shaped structure can extend outward from the housing 4 through the notch 46. Correspondingly, a hook hole or hook groove 47 is provided on the side wall of the housing 4. The end of the hook-shaped structure is a positioning hook end, which can be inserted into the hook hole or hook groove 47. More specifically, the positioning hook end of the hook-shaped structure is arranged with its opening facing upward, and the hook hole or hook groove 47 is provided on the side wall of the housing 4 above the notch 46.

[0063] In one possible implementation, the hook-shaped limiting member 3 is a positioning part 15, and the hook hole or hook groove 47 provided on the side wall of the housing 4 is a positioning member 2. By inserting the limiting member 3 into the hook hole or hook groove 47, the wire clamping member 1 is kept in the loose wire position or the locked wire position.

[0064] In another possible implementation, while the hook-shaped limiting member 3 of this embodiment is inserted into the hook hole or hook groove 47 of the housing 4, the positioning member 2 is locked in the positioning part 15 on the wire-locking member 1. Through the double positioning method, the wire-locking member 1 is kept in the loose wire position or the locked wire position.

[0065] For example, when the cable clamping component 1 is in the locked position, the hook-shaped limiting member 3 disengages from the hook hole or hook groove 47 of the housing 4, and the positioning member 2 also disengages from the positioning part 15 of the cable clamping component 1. When the cable clamping component 1 switches from the locked position to the loose position, it is only necessary to operate the hook-shaped structure to insert it into the hook hole or hook groove 47 of the housing 4, and at the same time, the positioning member 2 is locked in the positioning part 15 on the cable clamping component 1, and the cable clamping component 1 is held in the loose position. In this embodiment, when the cable clamping component 1 switches from the loose position to the locked position, the hook-shaped structure is pulled out from the hook hole or hook groove 47, and the positioning part 15 of the cable clamping component 1 disengages from the positioning member 2. Then, the hook-shaped structure is released, and the cable clamping component 1 moves to the loose position side under its own elastic force, and the cable clamping component 1 is held in the locked position.

[0066] For example, when the cable clamping component 1 is in the loose position, the hook-shaped limiting member 3 disengages from the hook hole or hook groove 47 of the housing 4, and the positioning member 2 also disengages from the positioning part 15 of the cable clamping component 1. When the cable clamping component 1 switches from the loose position to the locked position, it is only necessary to operate the hook-shaped structure to insert it into the hook hole or hook groove 47 of the housing 4, and at the same time, the positioning member 2 is locked in the positioning part 15 on the cable clamping component 1, and the cable clamping component 1 is then held in the locked position. In this embodiment, when the cable clamping component 1 switches from the locked position to the loose position, the hook-shaped structure is pulled out from the hook hole or hook groove 47, and the positioning part 15 of the cable clamping component 1 disengages from the positioning member 2. Then, the hook-shaped structure is released, and the cable clamping component 1 moves to the loose position side under its own elastic force, and the cable clamping component 1 is then held in the locked position.

[0067] Example 3 Combination Figure 7 As shown, based on Embodiment 2, this embodiment provides multiple hanging holes or hanging slots 47 vertically spaced on the side wall of the housing 4. Therefore, when the cable diameter to be positioned by the clamping hole 141 is large, the hook-shaped structure can be positioned on the housing 4 near the upper hanging hole or hanging slot, thereby increasing the pulling stroke of the clamping component 1 outward from the housing 4 and increasing the opening of the clamping hole 141. When the cable diameter to be positioned by the clamping hole 141 is small, the hook-shaped structure can be positioned on the housing 4 near the lower hanging hole or hanging slot, thereby reducing the pulling stroke of the clamping component 1 outward from the housing 4 and reducing the opening of the clamping hole 141.

[0068] Example 4 Based on any of the embodiments 1 to 3, this embodiment modifies the structure of the clamping hole 141 of the wire-locking member 11. In this embodiment, the clamping hole 141 on the wire-locking member 11 is replaced with a clamping groove. When the cable 5 is inserted, the cable 5 is inserted into the clamping groove but does not exit through it. As the wire-locking member 11 moves between the loose and locked positions, the opening size of the clamping groove changes synchronously. When the wire-locking member 11 is in the loose position, the opening of the clamping groove increases, allowing the inserted cable 5 to be pulled out; when the wire-locking member 11 is in the locked position, the opening of the clamping groove decreases, locking the inserted cable 5 in place.

[0069] Example 5 Based on any of the embodiments 1 to 3, this embodiment modifies the structure of the clamping hole 141 of the wire-locking member 11. In this embodiment, the clamping hole 141 on the wire-locking member 11 is replaced with a clamping bending section, that is, the wire-locking member 11 is set as a bending section. When the wire-locking member 11 is in the loose position, the bending section is away from the cable 5; when the wire-locking member 11 is in the locked position, the bending section hooks the cable 5 and locks the cable 5 under the elastic action of the elastic member 12.

[0070] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
