Description

Technical Field

[0001] The present invention relates to the technical field of wiring devices, and in particular to a toggle mechanism and a quick wiring device. Background Art

[0002] This section merely provides background information related to the present disclosure and may not constitute prior art.

[0003] Currently, when inserting wires into sockets, they are typically locked with screws, requiring specialized tools and expertise. During wiring, the wires are inserted between the screws and the socket piece, and then a specialized screwdriver is used. The torque required to tighten the screws is critical, making the operation inconvenient and slow, resulting in wasted time, labor, and efficiency.

[0004] To address this technical issue, a device currently available on the market utilizes a spring-type wire-gripping terminal for securing the wire. This terminal can be actuated by a toggle mechanism to lock or release the wire. During wiring operations, the operator simply actuates the toggle mechanism to secure the wire. However, the toggle mechanism in this wiring device protrudes from the housing surface. When the wiring device is placed in a wallbox, interference with the toggle mechanism can occur as the wire passes around it. This contact force between the wire and the toggle mechanism can cause the toggle mechanism to swing toward the spring-type wire-gripping terminal, preventing the wire from being secured. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the protruding shell of the toggle structure of the current wiring device easily interferes with the wires and causes the wires to be unable to be clamped, thereby providing a toggle mechanism and a quick wiring device.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] In a first aspect, the present invention provides a toggle mechanism, comprising:

[0008] A housing, wherein a first limiting portion is provided on an inner side wall of the housing;

[0009] A toggle structure is rotatably arranged inside the shell, and a second limiting portion is provided on the toggle structure. The toggle structure has a first position and a second position. When the toggle structure is in the first position or the second position, the second limiting portion is limited by the first limiting portion in the shell. When the toggle structure switches between the first position and the second position, the toggle structure swings.

[0010] Further optimizing the technical solution, the toggle structure includes:

[0011] A shift lever, wherein a receiving cavity is provided inside the shift lever;

[0012] The button is slidably arranged in the accommodating cavity inside the shift rod through an elastic component. The button includes a second limiting portion, which extends from a side wall of the shift rod relative to the first limiting portion.

[0013] Further optimizing the technical solution, when the toggle structure is in the first position and the button is not pressed, the second limiting portion is in relative contact with the first limiting portion to limit the toggle rod from swinging toward the side close to the first limiting portion;

[0014] When the toggle structure is in the first position and the button is pressed, the second limiting portion is misaligned with the first limiting portion, so that the toggle rod can swing toward the side closer to the first limiting portion;

[0015] When the toggle structure is in the second position and the button is not pressed, the second limiting portion abuts against the first limiting portion in a staggered manner to limit the swing of the toggle lever;

[0016] When the toggle structure is in the second position and the button is pressed, the second limiting portion is disengaged from the staggered abutment with the first limiting portion, so that the toggle rod can swing to a side away from the first limiting portion.

[0017] Further optimizing the technical solution, a sliding hole is opened on the side wall of the shifting rod opposite to the first limiting portion, and the second limiting portion passes through the sliding hole and can slide along the sliding hole through the elastic component;

[0018] When the first limiting portion and the second limiting portion are in misaligned abutment, the first limiting portion is limited in the sliding hole between the shifting rod and the second limiting portion.

[0019] To further optimize the technical solution, a pressing member is provided on the shell, and the toggle structure in the first position is released by applying force to the pressing member.

[0020] Further optimizing the technical solution, the pressing member includes:

[0021] a deformation portion connected to the housing;

[0022] A pressing portion, the pressing portion being arranged at the end of the deformation portion;

[0023] When a force is applied to the deformable portion, the deformable portion is deformed and the force is transmitted to the toggle structure through the pressing portion, so as to release the toggle structure in the first position.

[0024] To further optimize the technical solution, the toggle mechanism further includes a prying member, and an abutting protrusion is provided on the toggle structure;

[0025] When the toggle structure switches from the second position to the first position, the prying member is guided to the tripping force point by the abutment protrusion, so that when force is applied to the tripping force point, the second limiting portion and the first limiting portion are disengaged from the limit, and the toggle structure can swing to the side away from the first limiting portion.

[0026] To further optimize the technical solution, a socket is provided on the abutting protrusion to facilitate the passage of the prying member to operate the tripping force point.

[0027] In a second aspect, the present invention provides a quick connection device, comprising:

[0028] A toggle mechanism, wherein the housing of the toggle mechanism has at least one wire insertion hole suitable for inserting a wire;

[0029] At least one elastic wire-holding structure is disposed within the housing and has an unlocked position and a locked position; when the elastic wire-holding structure is in the unlocked position, the elastic wire-holding structure provides a reserved space for the wire, the reserved space being suitable for allowing the wire to be inserted into the housing through the wire insertion hole; when the elastic wire-holding structure is in the locked position, the elastic wire-holding structure is suitable for squeezing the wire inserted into the housing to lock the wire;

[0030] The toggle structure abuts against the elastic wire-holding structure. When the toggle structure is in the first position, the elastic wire-holding structure is in the unlocking position. When the toggle structure is in the second position, the elastic wire-holding structure is in the locking position.

[0031] To further optimize the technical solution, the shell is provided with a prying member socket connected to the inner cavity of the shell, so that the prying member can pass through the prying member socket to pry the toggle structure.

[0032] The technical solution of the present invention has the following advantages:

[0033] The present invention provides a toggle mechanism in which the toggle structure is completely sunken and contained within the housing in either the first or second position, without protruding from the housing surface. Consequently, wires passing through the housing avoid direct contact with the toggle structure, completely eliminating interference issues caused by contact between the wires and the toggle structure and improving the spatial compatibility and operational safety of the wiring device. Furthermore, because the toggle structure is sunken within the housing in either the first or second position, it lacks a noticeable presence, resulting in a more aesthetically pleasing appearance.

[0034] In the present invention, through the cooperation between the first limiting portion and the second limiting portion, the toggle structure can achieve precise mechanical locking in both the first position and the second position, thereby preventing malfunction caused by external force or vibration.

[0035] The present invention is suitable for use in confined spaces such as wall boxes. The toggle mechanism does not take up additional space, preventing interference with wires. After the wires are locked, the force applied is directly transmitted to the housing, preventing the toggle mechanism from changing position or failing due to the force.

[0036] The user can switch positions simply by swinging the toggle mechanism without specialized tools or complex operations, quickly locking and releasing the wires, significantly reducing wiring difficulty and saving manpower and time. The first and second stoppers ensure that the toggle mechanism automatically locks in place, preventing loosening and reducing repeated adjustments. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0052] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0053] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0054] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] Currently, when a wire is inserted into a socket, it is usually necessary to lock the wire with a screw, and professional tools and professionals are required for wiring. During the specific wiring, the wire is inserted between the screw and the socket piece, and then a professional screw-locking electric screwdriver is used. The torque must reach the required value to lock the screw. The user operation is not very convenient, the wiring time is slow, and time and manpower are wasted, which is inefficient. In order to solve this technical problem, there is currently a structure on the market that uses a spring-type wire clamping terminal to clamp the wire. The spring-type wire clamping terminal can be driven by a toggle structure to enable the spring-type wire clamping terminal to clamp or release the wire. When performing wiring operations, the operator only needs to drive the toggle structure to lock the wire. However, the toggle structure in the wiring device protrudes from the surface of the shell. When the wiring device product is placed in the wall box, if the wire bypasses the toggle structure, there will be interference with the toggle structure. In this case, the wire is subjected to force when in contact with the toggle structure, which may cause the toggle structure to swing to the side of the spring-type wire clamping terminal, resulting in the spring-type wire clamping terminal being unable to clamp the wire. Combined with Figure 5 As shown, when locking the wire, the toggle structure 2 swings toward one side of the partition 11. When the wire passes around the gap position 7 between the partition and the toggle structure, the wire will force the toggle structure to swing to the other side, that is, to the side of the spring-type wire clamping terminal, causing the spring-type wire clamping terminal to move and fail to clamp the wire.

[0056] Based on this, the present invention provides a toggle mechanism that, when in its first or second position, is completely sunken within the housing, eliminating any convex housing surface and thus avoiding this problem. Furthermore, the toggle mechanism, when in its first or second position, is sunken within the housing cavity, resulting in an aesthetically pleasing overall appearance without any obtrusiveness.

[0057] The specific embodiments of the present invention are described in detail below in conjunction with the toggle mechanism of the first aspect of the present invention and the quick connection device of the second aspect of the present invention.

[0058] Example 1

[0059] Combine Figures 1 to 4 As shown, according to an embodiment of the present invention, in a first aspect, a toggle mechanism is provided, comprising a housing 1, a first limiting portion 12, a toggle structure 2, and a second limiting portion 23. The first limiting portion 12 is provided on the inner side wall of the housing 1. The toggle structure 2 is rotatably disposed within the housing 1, and the second limiting portion 23 is provided on the toggle structure 2. The toggle structure 2 has a first position and a second position. When the toggle structure 2 is in the first position or the second position, the second limiting portion 23 is limited by the first limiting portion 12 within the housing 1. When the toggle structure 2 switches between the first position and the second position, the toggle structure 2 swings.

[0060] It should be noted that the housing 1 in this embodiment can be a socket housing or a housing of other products. This embodiment can be applied to socket products, but is not limited to socket products.

[0061] In this embodiment, the toggle structure 2 is housed within the housing 1. More specifically, when the toggle structure 2 is in its first position, i.e., the wire unlocking position, the toggle structure 2 is completely sunken and housed within the housing 1. Alternatively, when the toggle structure 2 is in its second position, i.e., the wire locking position, the toggle structure 2 is completely sunken and housed within the housing 1. When the toggle structure 2 is swinging, i.e., switching positions, it can either be completely sunken within the housing 1 or partially extended from the housing 1.

[0062] Because the toggle mechanism 2 of this embodiment has two locked positions, namely a first position and a second position, and when in these two locked positions, the toggle mechanism 2 is completely sunken and accommodated within the housing 1, not protruding from the surface of the housing 1. Consequently, the wires passing through the housing do not come into direct contact with the toggle mechanism. This completely eliminates the interference problem caused by the wires 6 contacting the toggle mechanism 2, improving the spatial compatibility and operational safety of the wiring device. Furthermore, because the toggle mechanism 2 is sunken within the housing 1 in both locked positions, it does not appear obtrusive, resulting in a more aesthetically pleasing appearance.

[0063] Through the cooperation between the first limiting portion 12 and the second limiting portion 23 , the toggle structure 2 can achieve precise mechanical locking in both the first position and the second position, thereby preventing malfunction caused by external force or vibration.

[0064] This toggle mechanism is ideal for use in confined spaces such as wall boxes. It doesn't take up additional space and prevents interference with wires. After tightening the wires, the force applied is directly transmitted to the housing, preventing the toggle mechanism from shifting or failing due to the applied force.

[0065] The user can switch positions by simply swinging the toggle mechanism without specialized tools or complex operations, quickly locking and releasing the wires, significantly reducing wiring difficulty and saving manpower and time. The first and second stoppers 12 and 23 ensure that the toggle mechanism automatically locks once in place, preventing loosening and reducing repeated adjustment time.

[0066] In some embodiments, the toggle mechanism 2 includes a lever 21 and a button 22. The bottom end of the lever 21 is rotatably mounted on a positioning seat 13 within the housing 1 via a rotating shaft 212. A chamber is provided within the lever 21. The button 22 is slidably mounted within the chamber within the lever 21 via an elastic assembly. One end of the button 22 extends from the chamber, and a second stop 23 is connected to the side wall of the button 22. A slot or hole is provided on one side of the lever 21 opposite the first stop, allowing the second stop 23 on the button 22 to extend from the side wall of the lever 21 and engage with the first stop. In this embodiment, when the button 22 is pressed, it compresses the elastic assembly, allowing the second stop 23 to slide within the lever 21 with it. The elastic assembly provides the button with an automatic reset function, allowing it to quickly return to its original position upon release. Active pressure is required to trigger the second stop to slide, preventing malfunctions caused by inadvertent contact with the lever during daily use and enhancing safety.

[0067] The elastic assembly includes a spring 24, one end of which is connected to the bottom wall of the accommodating cavity, and the other end of which is connected to the bottom wall of the button 22. A sliding hole or slot is provided inside the button 22, and a limit shaft 214 is fixedly provided on the lever 21. The limit shaft 214 passes through the sliding hole or slot to limit the sliding movement of the button 22.

[0068] In some embodiments, if the first limiting portion 12 and the second limiting portion 23 are a snap-fit structure, the user may mistakenly push the lever without pressing the button. Since the hook of the lever and the hook positioning portion are in a hooked and positioned state, when the lever is forcibly pushed, the hook on the button and the hook positioning portion on the shell may be forcibly disengaged, which may easily cause the hook and / or the hook positioning portion to break.

[0069] In order to solve the above problem, in this embodiment, when the toggle structure 2 is in the first position ( Figure 1 When the toggle structure 2 is positioned on the left side of the housing 1, neither the lever 21 nor the button 22 extends from the housing 1. When the button 22 is not pressed, the second limiter 23 abuts against the first limiter 12 to restrict the lever 21 from swinging in the first direction (towards the side closest to the first limiter 12). This increases the stability of the overall structure and prevents accidental movement of the lever 21, leading to erroneous operation. Furthermore, the coordination between the first limiter 12 and the second limiter 23 ensures the stability of the lever 21 in a specific position, improving operational accuracy. When the button 22 is pressed, the second limiter 23 is offset from the first limiter 12, allowing the lever 21 to swing closer to the first limiter 12. The user simply presses the button, causing the second limiter 23 to shift with the first limiter 12, allowing the lever 21 to swing easily, thus enhancing the user experience.

[0070] When the toggle structure 2 is in the second position ( Figure 1 When the lever 21 and button 22 are not extended from the housing 1 (the position of the toggle structure 2 on the right side), the lever 21 and button 22 are not extended from the housing 1. When the button 22 is not pressed, the second limiter 23 abuts against the first limiter 12 in an offset manner, thereby limiting the swing of the lever 21. When the button 22 is pressed, the second limiter 23 disengages from the offset abutment with the first limiter 12, allowing the lever 21 to swing in the second direction (away from the first limiter 12).

[0071] In this embodiment, the swing of the lever 21 requires the simultaneous pressing of the button 22 to trigger the misalignment of the first limit portion 12 and the second limit portion 23, thereby completely avoiding damage to the mechanism caused by accidentally pushing the lever, thereby improving safety.

[0072] In some embodiments, a sliding hole 211 is defined on a side wall of the lever 21 opposite to the first limiting portion 12 , and the second limiting portion 23 passes through the sliding hole 211 and can slide along the sliding hole 211 via an elastic component.

[0073] When the first limiting portion 12 and the second limiting portion 23 are misaligned and abutted, the first limiting portion 12 is retained within the sliding hole 211 between the lever 21 and the second limiting portion 23. More specifically, when the button 22 is pressed within the sliding hole 211, a slot is created within the sliding hole 211 between the lever 21 and the second limiting portion 23, which can be referred to as a receiving slot 221. When the button 22 is pressed and the lever 21 is able to swing toward the side closer to the first limiting portion 12, the first limiting portion 12 passes through the sliding hole 211 and is received within the receiving slot 221. The sidewalls of the button 22 relative to the receiving slot 221 can match the shape of the first limiting portion 12, allowing the first limiting portion 12 to be more securely retained within the receiving slot 221.

[0074] In this embodiment, when the button 22 is pressed, the first stopper 12 passes through the sliding hole 211 and enters the receiving groove 221, forming a reliable locking mechanism. This ensures that the lever 21 remains stable in the desired position and prevents it from loosening due to external forces or vibration. Furthermore, after the first stopper 12 is received in the receiving groove 221, the elastic component exerts a compressive force on the button 22, creating a compressive force between the first stopper 12 and the second stopper 23, thereby more stably locking them. This locking mechanism prevents the lever 21 from easily changing position unless the button 22 is pressed again, reducing the risk of misoperation.

[0075] In some embodiments, a pressing member 4 is provided on the housing 1 , and the toggle structure 2 in the first position is released by applying force to the pressing member 4 .

[0076] As a specific embodiment, when the toggle structure 2 is in the first position, the pressing member 4 faces the button 22 and contacts and engages with the button 22. In this embodiment, because the pressing member 4 is disposed outside the housing 1, it is convenient for the user to press the button. The pressing member 4 acts as an external force transmission medium, transmitting the pressing force applied by the user to the button 22, thereby achieving the pressing of the button 22.

[0077] As an alternative embodiment, when the toggle structure 2 is in the first position, the pressing member 4 may not directly contact the key 22. Only after the pressing member 4 is pressed, the pressing member 4 contacts the key 22 and applies force to the key 22.

[0078] As an alternative embodiment, when the toggle structure 2 is in the first position, force can also be transmitted between the pressing member 4 and the button 22 through an intermediate member. The intermediate member can be a closed film or other structure, and its specific structure is not limited here.

[0079] More specifically, the pressing member 4 includes a deformation portion 41 and a pressing portion 42. The deformation portion 41 is detachably connected to the shell 1 or integrally connected, and the deformation portion 41 can extend to the position of the toggle structure 2. The pressing portion 42 is provided at the end of the deformation portion 41, and the pressing portion 42 can at least partially extend into the interior of the shell 1. When the user presses the deformation portion 41, the deformation portion 41 can be deformed, thereby pressing the pressing portion 42 to move and press the button 22. When the toggle structure 2 is in the first position, after the button 22 is pressed by the pressing member 4, an external tool can be inserted into the shell 1 to toggle the toggle lever 21 to cause it to swing, or the elastic clamping wire structure abutting against the toggle lever 21 can be used to automatically drive the toggle lever 21 to swing.

[0080] The housing 1 may be provided with a press member through-hole, which facilitates the passage of the press portion 42 of the press member 4, allowing the press portion 42 to enter the housing 1 and thereby exert force on the button 22. As an alternative embodiment, the housing 1 may not be provided with a press member through-hole, and the press portion 42 of the press member 4 may transmit force to the button 22 of the toggle structure 2 via a deformable material such as a closed film, thereby improving the sealing performance of the device.

[0081] In some embodiments, the toggle mechanism further includes a prying member, which is a tool. The tool can be a rod-shaped tool or a tool of other shapes, and its specific structure is not limited here. The prying member is used to pry the toggle structure 2 when the toggle structure 2 is in the second position, so that it changes its position state. The prying member is separately provided with the toggle structure 2 and the housing 1. The prying member is an external tool and is only used to intervene in the prying when the position needs to be switched, thereby avoiding accidental swing of the toggle structure due to accidental touch during daily use.

[0082] In some embodiments, the toggle lever 21 is provided with an abutting protrusion 213 on the top of the side wall facing the first limiting portion 12. When the toggle structure 2 is in the second position, the abutting protrusion 213 abuts against the side wall where the first limiting portion 12 is located. The abutting protrusion 213 is provided with an inclined surface, which is used to guide the prying member to be inserted into the tripping force application point when the toggle structure 2 is in the second position, so that when a force is applied to the tripping force application point, the second limiting portion 23 and the first limiting portion 12 are disengaged, and the toggle structure 2 can swing away from the first limiting portion 12. More specifically, when the prying member is inserted into the tripping force application point and a force is applied to the tripping force application point, the button 22 is squeezed, causing the first limiting portion 12 and the second limiting portion 23 provided on the button 22 to be disengaged, thereby allowing the toggle structure 2 to swing away from the first limiting portion 12. The sidewall of the abutting protrusion 213 is provided with a socket 215 to facilitate the passage of a prying member to operate the tripping force point. The opening direction of the socket 215 can be arranged along the axis of the lever 21 or in other directions that are convenient for applying force, and the specific direction is not limited here.

[0083] In this embodiment, socket 215 provides a clear insertion path for the prying member, ensuring that the prying force is precisely applied to the designated location of lever 21, preventing scratches on the housing or the prying structure caused by slippage of the prying member. Even in a narrow installation environment (such as embedded in a wall box), the user can still apply force accurately through the socket, avoiding problems such as inoperability or incomplete operation due to space constraints. The size and position of socket 215 are compatible with common tools (such as flat-head and Phillips screwdrivers), eliminating the need for specialized prying accessories and lowering the user's entry level.

[0084] As a preferred embodiment, the inner side wall of the shell 1 includes a partition 11, and the first limiting portion 12 is provided on the partition 11. When the toggle structure 2 switches from the second position to the first position, the prying member uses the end side wall of the partition 11 as the prying fulcrum 16 to pry the toggle rod 21, so that the second limiting portion 23 is disengaged from the first limiting portion 12, and the toggle structure 2 can swing to the side away from the first limiting portion 12. When the prying member uses the end side wall of the partition 11 as a fulcrum to apply force to the toggle rod 21, the lever effect is used to amplify the operating torque and reduce the force required to be applied by the user. In a narrow space, the toggle structure state can be quickly switched by the prying member to avoid the problem of insufficient force due to insufficient operating space.

[0085] Example 2

[0086] Combine Figures 1 to 4 As shown, according to an embodiment of the present invention, in a second aspect, a quick connection device is provided, comprising an elastic wire clamping structure and the toggle mechanism of embodiment 1.

[0087] The housing 1 of the toggle mechanism has at least one wire insertion hole 14 suitable for inserting a wire 6 .

[0088] At least one elastic wire-holding structure is provided, disposed within the housing 1, and has an unlocked position and a locked position. When in the unlocked position, the elastic wire-holding structure provides a reserved space for the wire 6, which is suitable for allowing the wire to be inserted into the housing 1 through the wire insertion hole 14. When in the locked position, the elastic wire-holding structure is suitable for squeezing the wire 6 inserted into the housing 1 to lock the wire 6.

[0089] The toggle structure 2 abuts against the elastic wire-holding structure and is adapted to control the switching between the unlocking position and the locking position of the elastic wire-holding structure. When the toggle structure 2 is in the first position, the elastic wire-holding structure is in the unlocking position, and when the toggle structure 2 is in the second position, the elastic wire-holding structure is in the locking position.

[0090] The aforementioned quick wiring device utilizes a lever 21 to control the state of the elastic wire-holding structure, making it easy for the operator to operate. Movement of the lever 21 drives the elastic wire-holding structure, which squeezes the wire, securing it. Compared to traditional methods of tightening wires with screws, this device eliminates the need for any wiring tools. Operators simply need to activate the lever 21 to secure the wires, making wiring easier for ordinary household workers. This improves wiring efficiency and saves labor.

[0091] In some embodiments, the shell 1 is provided with a prying member socket 15 connected to the inner cavity of the shell, so that the prying member can pass through the prying member socket 15 to pry the toggle structure 2, thereby quickly converting the toggle structure 2 from the second position to the first position, thereby achieving the purpose of quickly loosening the line.

[0092] In some embodiments, the elastic wire clamping structure includes a plug-in terminal 5 and a spring-type wire clamping terminal 3. The plug-in terminal 5 is arranged inside the housing 1. The spring-type wire clamping terminal 3 is bent and elastic, with one end fixed on the plug-in terminal 5 and the other end used to lock the wire 6. The spring-type wire clamping terminal 3 has an unlocking position for inserting the wire and a locking position for locking the wire. When the spring-type wire clamping terminal 3 is in the unlocking position, the second limiting portion 23 is in relative contact with the first limiting portion 12, and the lever 21 squeezes the spring-type wire clamping terminal 3. When the spring-type wire clamping terminal 3 is in the locking position, the lever 21 swings to the side away from the spring-type wire clamping terminal 3, and the second limiting portion 23 is misaligned with the first limiting portion 12. At this time, the spring-type wire clamping terminal 3 locks the wire.

[0093] More specifically, the spring-type clamping terminal 3 includes a positioning section 31, an extrusion section 32, and a clamping section 33. The positioning section 31 is connected to the plug terminal 5. The extrusion section 32 is connected to the positioning section 31 and forms an unclosed extrusion ring with the positioning section 31. The end of the extrusion ring, away from the positioning section 31, abuts against the side wall of the lever 21. The extrusion ring has an expanded configuration in an expanded state and a compressed configuration in an extruded state. The clamping section 33 is connected to the extrusion section 32 and is shaped like a hook.

[0094] In this embodiment, the hook-shaped engaging section 33 is designed to increase the contact area with the wire. When clamped, the engaging section 33 can penetrate the wire, forming a barb during wire removal, thereby enhancing the wire's resistance to extraction. In practice, if clamping force is not a concern, the engaging section 33 can be flat.

[0095] When the toggle structure 2 switches from the second position to the first position, the toggle rod moves toward the side close to the extrusion section 32 and compresses the extrusion ring. At this time, the extrusion ring is in a compressed configuration and is pressed toward the side away from the positioning section 31, so that the extrusion ring no longer locks the wire.

[0096] When the toggle mechanism 2 switches from the first position to the second position, pressing the button 22 causes the squeeze ring to expand under the action of the elastic force. At this point, the squeeze ring is in the expanded configuration, driving the toggle mechanism 2 to automatically swing toward the second position. The engaging section 33 presses toward the side closer to the positioning section 31, thereby locking the wire. The method of this embodiment is very convenient for locking the wire, as it only requires controlling the state of the squeeze ring.

[0097] The present invention performs the following wiring steps for the conductors:

[0098] In the initial state, the toggle structure 2 is in the first position. The user inserts the wire 6 into the wire insertion hole 14. By pressing the pressing member 4, the fit between the first limiting portion 12 and the second limiting portion 23 is loosened. At this time, the first limiting portion 12 and the second limiting portion 23 no longer abut each other, and the first limiting portion 12 and the second limiting portion 23 are misaligned. The extrusion ring of the spring-type clamping terminal 3 changes from a compression configuration to an expansion configuration, pushing the toggle structure 2 in the first direction. At this time, the spring-type clamping terminal 3 expands in the first direction, driving the clamping section 33 to move in the first direction. The hook of the clamping section 33 contacts the wire 6, and the clamping section 33 and the plug terminal 5 work together to lock the wire 6.

[0099] The present invention performs the following steps for taking out the wire:

[0100] The user uses a rod-shaped tool to pry the toggle structure 2, causing it to move in the second direction, thereby shifting the toggle structure 2 from the second position to the first position. The spring-type wire-holding terminal is reset, and the engaging section 33 now moves in the opposite direction of the wire 6, disengaging from the engaging section 33. The spring 24 within the toggle lever 21 pushes the button 22 outward due to its elastic force. When the toggle lever 21 swings to the first position (i.e., the first position of the toggle structure 2), the second stop 23 on the button 22 abuts and engages with the first stop 12 on the housing, unlocking the spring-type wire-holding terminal. The reserved space is not clamped on the wire 6, allowing the wire 6 to be easily removed.

[0101] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
