Specific embodiments

[0020] The technical solutions of the present application will be described below in conjunction with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, and all the other embodiments obtained by those of ordinary skill in the art without creative work based on these drawings also belong to the protection scope of the present application.

[0021] At present, when the cable is inserted into the socket, it is usually necessary to lock the cable by screw, and professional tools and personnel are needed for wiring. In the specific wiring, the cable is inserted between the screw and the socket sheet, and then a professional locking screw electric batch 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, time and manpower are wasted, and the efficiency is low.

[0022] In order to solve this technical problem, a new type of structure using a spring sheet type wire clamping terminal to clamp the wire has emerged in the market. As shown in Figure 6 The wire clamping part 1 includes a positioning section 122, an extrusion section 124 and a clamping section 123 connected in sequence, and an unsealed extrusion ring is formed between the positioning section 122 and the extrusion section 124. The unsealed extrusion ring and the clamping section need to be driven by the lever structure 7 to move, and then the clamping section realizes the functions of clamping the wire or releasing the wire. However, the lever structure 7 directly abuts on the extrusion ring, and the movement of the lever structure 7 is needed to drive the extrusion ring to deform. The extrusion ring of the wire clamping part 1 is arranged inside the shell 4. In order to facilitate the operation of the lever structure 7, the lever structure 7 often needs to be arranged partly inside the shell 4 and partly exposed outside the shell 4, which leads to a larger volume of the lever structure 7 and occupies a larger space inside the shell 4, making the product structure more complex. The lever structure 7 needs to be assembled into the shell to be normally used, which undoubtedly increases the assembly difficulty and leads to the increase of part cost and manual assembly cost.

[0023] Based on this, the application provides a wiring device, which sets the wire clamping part as an elastic member and a wire locking member, sets the wire locking member as a first end and a second end, the first end is connected to the elastic member, and the second end is a free end and extends to a preset operation range, so that the control of wire locking and wire releasing can be realized by directly operating the second end of the wire locking member, the operation steps are significantly simplified, the space occupation inside the shell is reduced, the assembly efficiency is improved and the manufacturing cost is reduced.

[0024] In addition, since the lever structure 7 in the technology directly abuts on the extrusion ring of the wire clamping part 1, the contact part of the lever structure 7 and the extrusion ring is easy to wear after long time use, which affects the accuracy of driving the extrusion ring to deform.

[0025] Correspondingly, the wiring device provided by the application directly operates the second end (free end) of the wire locking member, does not need to pass through any intermediate transmission part, thereby completely eliminating the contact wear problem, ensuring that the force transmission for driving the wire locking member is more direct and accurate, and further reducing the maintenance requirement and potential failure rate.

[0026] The specific embodiments of the application will be described in detail below in combination with the wiring device of the application.

[0027] In combinationFigures 1 to 5 As shown, according to the embodiment of the present application, a wiring device is provided, comprising a housing 4 and a wire clamping component 1. The housing 4 comprises a cable opening 43. The wire clamping component 1 is installed in the housing 4, and the wire clamping component 1 comprises an elastic member 12 and a wire locking member 11. The wire locking member 11 comprises a first end connected to the elastic member 12 and a second end extending to a preset operating range.

[0028] By applying force or mechanical energy to the second end in the preset operating range, the elastic member 12 deforms, so that the wire locking member 11 moves between the wire loosening position and the wire locking position. The wire loosening position refers to a position that can pull out the cable 5, and the wire locking position refers to a position that can lock the cable 5. The movement of the wire locking member 11 between the wire loosening position and the wire locking position can achieve the locking or pulling out of the cable 5.

[0029] It should be noted that the preset operating range refers to the range that can be operated by hand. However, in some specific scenarios, in order to achieve better operation effect, tools such as screwdrivers can be used for auxiliary operation. For example, in the scenario where the wiring device is installed in a narrow gap or embedded installation slot, the space for manual operation is limited. The screwdriver or the like can be used as a force transmission medium to replace the finger to contact the second end of the wire locking member in the limited space, and the deformation degree of the elastic member 12 can be more accurately controlled through rotation or pushing operation, so as to ensure that the wire locking member 11 is stably switched to the target position.

[0030] In the present application, the second end is a free end, which is not connected to any position on the elastic member 12, providing sufficient redundant space for operation. Whether it is directly contacted by hand or indirectly applied by tools, there will be no motion interference due to the connection between the second end and the elastic member 12.

[0031] The elastic member 12 and the wire locking member 11 are integrated, and the integrated structure enables the elastic force of the elastic member 12 to be directly and uniformly transmitted to the wire locking member 11. When the force or mechanical energy is applied to the second end (free end) of the wire locking member 11, the elastic member 12 can be deformed by a corresponding degree at the same time, ensuring that the switching action of the wire locking member 11 between the wire loosening position and the wire locking position is coherent and accurate.

[0032] The above wiring device simplifies the operation process, and does not require professional personnel. The locking and unlocking of the cable 5 can be achieved by directly driving the wire locking member 11 by external force, which is more convenient for users to operate, and achieves the function of conveniently clamping and taking out the cable 5. The torque control step required by the traditional screw locking is omitted, the wiring time is reduced, the labor cost is saved, and the overall work efficiency is improved.

[0033] The above wiring device can directly complete the loosening and locking of the cable 5 by directly manually or by means of a tool on the second end of the locking member 11 within a preset operating range, that is, directly taking the second end of the locking member 11 as an operating handle, and further without equipping the wiring device with other components for driving the second end to move, thereby reducing the types and quantity of components and making the overall volume of the device smaller, and being particularly suitable for the design of small and integrated electrical equipment.

[0034] When the cable clamping component 1 is installed on the shell 4, a direct assembly and fixation of the cable clamping component 1 and the shell 4 can be adopted, or the cable clamping component 1 is first assembled on the conductive sheet 44, and then the cable clamping component 1 is indirectly assembled and fixed by fixing the conductive sheet 44. The specific assembly and fixation modes include slot limiting installation, welding and other feasible implementation modes. It should be noted that the second end of the cable clamping component as a free end needs to be extended to a preset operating position.

[0035] In some embodiments, the locking member 11 is provided with a wire clamping hole 141, and the opening of the wire clamping hole 141 changes when the elastic member 12 is deformed, so that the locking member 11 moves between the locking position and the loosening position to lock or loosen the inserted cable 5. In this embodiment, the wire clamping hole 141 is a hole structure, and the cable forms a circumferential contact with the hole wall after being inserted. Compared with the traditional single-point extrusion of a screw or the local clamping of a spring piece, the contact area is larger, the clamping force is more evenly distributed, the risk of loosening of the cable due to vibration or pulling is reduced, and the stability of the electrical connection is improved.

[0036] More specifically, the locking member 11 is provided with a through hole 14, and the third end of the elastic member 12 not connected with the locking member 11 is movably inserted through the through hole 14, so as to divide the through hole 14 into the wire clamping hole 141 and the movable hole 142. When the locking member 11 moves, the elastic member 12 relatively displaces in the movable hole 142, so that the hole diameter of the wire clamping hole 141 changes. For example, when the locking member 11 moves towards the side close to the elastic member 12, the hole diameter of the wire clamping hole 141 decreases, and the hole diameter of the movable hole 142 increases, so as to lock the inserted cable 5. When the locking member 11 moves away from the elastic member 12, the hole diameter of the wire clamping hole 141 increases, and the hole diameter of the movable hole 142 decreases, so as to loosen the inserted cable 5.

[0037] The wire clamping hole 141 is formed by the through hole 14 being separated by the elastic member 12, and the edge thereof can be a continuous hole wall structure to enhance the rigidity of the locking member 11. When the hole diameter of the wire clamping hole 141 decreases, the elastic member and the locking member can interact, thereby clamping the cable 5. Compared with the single-point or line contact of the traditional spring piece terminal, the contact area is larger, and the clamping is more stable and firm.

[0038] In addition, a gap is left between the third end of the elastic member 12 and the hole wall of the through hole 14, which provides stable guidance for the movement of the wire clamping member 11 and avoids friction jam between the two.

[0039] As an alternative embodiment, the third end does not move out of the through hole 14, and the third end is directly fixed on the shell 4. The shell 4 is provided with a post that passes through the through hole 14 and divides the through hole 14 into a wire clamping hole 141 and a movable hole 142. For example, the circumferential surface of the post can be an arc-shaped groove, an arc-shaped convex groove, or a flat surface, i.e., the post is a rectangular post. In this embodiment, the axial direction of the post is perpendicular to the moving direction of the wire clamping member 11, and the post is directly cooperated with the wire clamping member 11 and the shell 4. During the wire clamping and wire loosening processes, the post can ensure that the third end is fixed, and only the relative displacement between the wire clamping member 11 and the post occurs to change the opening of the wire clamping hole 141.

[0040] Further, a gap can be left between the post and the hole wall of the through hole 14, which provides stable guidance for the movement of the wire clamping member 11 and avoids friction jam between the two.

[0041] In some embodiments, the wire clamping component 1 can be fixed on the conductive sheet 44 through the through hole 14. Specifically, in combination with Figure 1 As shown, the conductive sheet 44 is provided with an assembly structure 46 that can be cooperated with the through hole 14 to fix the wire clamping component 1 on the conductive sheet 44, and the conductive sheet 44 is limited by the conformal limiting groove in the shell 4, so that the wire clamping component 1 can be fixed in the shell 4. The assembly structure 46 can be a hook or a column. For example, during assembly, the third end is moved to the side away from the wire clamping member 11 by extrusion to expand the hole diameter of the wire clamping hole 141 in the through hole 14, and then the assembly structure 46 on the conductive sheet 44 is inserted into the wire clamping hole 141 of the through hole 14, and the third end is released. The third end can be moved to the side close to the wire clamping member 11 under the influence of elastic force to reduce the hole diameter of the wire clamping hole 141, so that the assembly structure 46 on the conductive sheet 44 is tightly clamped in the wire clamping hole 141, and the wire clamping component 1 is fixed on the conductive sheet 44. This assembly method does not need to weld the wire clamping component 1 and the conductive sheet 44, which reduces the assembly difficulty and avoids the risk that the welding point falls off during subsequent use to cause the wire clamping component 1 to be unable to be fixed in the shell 4, thereby enhancing the assembly reliability.

[0042] More specifically, the elastic member 12 comprises a connecting segment 121 and a positioning segment 122, the first end of the locking wire member 11 is fixedly connected to one end of the connecting segment 121, and the other end of the connecting segment 121 is connected to one end of the positioning segment 122; the other end (i.e. the third end) of the positioning segment 122 is movably inserted into the through hole 14. Under this connection structure, the outer wall of the positioning segment 122 and the wall surface of the through hole 14 away from the connecting segment 121 form a wire clamping hole 141 through which the cable 5 can pass. When the wire clamping part 1 is installed in the shell 4, the positioning segment 122 remains stationary relative to the shell 4. When no external force acts on the second end of the locking wire member 11, the elastic member 12 is in the initial position due to its own elasticity, at this time, the inner wall of the through hole 14 away from the connecting segment 121 is tightly attached to the outer wall of the positioning segment 122, the opening of the wire clamping hole 141 is the smallest, and the opening of the movable hole 142 is the largest; when an external force acts on the second end of the locking wire member 11 and moves it away from the connecting segment 121, since the positioning segment 122 is stationary relative to the shell 4, the inner wall of the through hole 14 away from the connecting segment 121 will be separated from the outer wall of the positioning segment 122, the opening of the wire clamping hole 141 will increase, and the opening of the movable hole 142 will be the smallest. Through this structure, the opening of the wire clamping hole 141 can be changed, and the switching of the wire clamping part 1 between the locked wire position and the unlocked wire position can be completed.

[0043] The embodiment optimizes the structural design, controls the opening change of the wire clamping hole 141 formed by the cooperation of the locking wire member 11 and the positioning segment 122 through the movement of the locking wire member 11, and then realizes locking or unlocking, without complex multi-step operation or tool assistance throughout the process, and a single person can easily realize the installation, adjustment and disassembly of the cable, greatly improving the operation efficiency. And when no external force acts on the second end of the locking wire member 11, the elastic member 12 maintains the initial state by relying on its own elasticity, so that the opening of the wire clamping hole 141 is the smallest, continuously providing stable clamping force when clamping the cable later, effectively avoiding accidental loosening of the cable due to vibration, pulling and other accidents; at the same time, the design that the positioning segment 122 is stationary relative to the shell 4 can reduce the risk of locking failure caused by structural deviation, and further ensure the locking stability.

[0044] The locking wire member 11, the connecting segment 121 and the positioning segment 122 form an unsealed extrusion ring. The wire clamping part 1 is an elastic member, when the wire clamping part 1 is in the locked wire position, the extrusion ring is in an expanded configuration, when the wire clamping part 1 is in the unlocked wire position, the extrusion ring is in a compressed configuration, and the elastic potential energy is stored. When the external force on the second end is removed and the wire clamping part 1 is switched from the unlocked wire position to the locked wire position, the extrusion ring expands under the action of its own elastic force, and the opening of the wire clamping hole 141 is reduced to clamp the cable 5. In this embodiment, the rapid automatic locking is realized through the integrated elasticity of the components, the structure is simplified, the number of parts is reduced, and the assembly complexity and cost are reduced. When the extrusion ring expands, a continuous inward tightening force is generated on the locking wire member 11, so that the inner wall of the wire clamping hole 141 and the cable 5 maintain stable pressure contact.

[0045] In some embodiments, the preset operation range protrudes from the outer surface of the shell 4, and the user can directly exert force (e.g., press or push) on the second end of the locking wire member 11 outside the shell 4, which is simpler than the traditional screw locking method, without the need to disassemble the shell 4 and expose the internal structure, thereby greatly simplifying the wiring process. In addition, by directly exerting force on the second end, the force exertion stroke can be shorter, and the time consumed by the force transmission process can be reduced, thereby achieving faster and more stable wiring. Alternatively, the preset operation range is flush with the outer surface of the shell 4, keeping the surface of the shell 4 smooth and avoiding external interference or accidental touch, thereby enhancing the reliability and durability of the overall device. Alternatively, the preset operation range is arranged inside the shell 4, and the user drives the second end by inserting a screwdriver or other tool into the shell 4.

[0046] The preset operation range arranged outside the shell 4 or flush with the outer surface of the shell 4, compared with the preset operation range arranged inside the shell 4, does not need to reserve space for the hand or tool to extend into the shell 4, thereby reducing the volume of the shell 4, suitable for scenarios where the installation space is limited, and improving the scene adaptability of the product.

[0047] Further, the preset operation range and the cable opening 43 are arranged on different walls of the shell 4, and the preset operation range does not interfere with the cable 5 at the cable opening 43. For example, the preset operation range is arranged on the side of the shell 4, and the cable opening 43 is arranged on the top or bottom of the shell 4. For another example, the preset operation range is arranged on the top or bottom of the shell 4, and the cable opening 43 is arranged on the side of the shell 4.

[0048] In some embodiments, considering that when the locking wire member 11 is in the loose wire position, the locking wire member 11 needs to be continuously exerted by force due to the elastic force of the locking wire member 11 itself, otherwise the locking wire member 11 will reset under the elastic force, increasing the operation difficulty. Therefore, in the present application, the shell 4 is provided with a positioning member 2, which cooperates with the second end of the locking wire member 11 to keep the locking wire member 11 in the loose wire position or the locked wire position. Correspondingly, the present embodiment can keep the locking wire member 11 in a fixed position without the need to continuously exert force on the locking wire member 11.

[0049] The second end of the locking wire member 11 is provided with a positioning portion 15, which forms a matching positioning structure with the positioning piece 2 installed on the shell 4. The two can be fixed in a specific position through the cooperation of engagement or disengagement, effectively preventing accidental movement of the locking wire member 11 in a non-operating state. Among them, the positioning piece 2 and the positioning portion 15 can be matched in a concave-convex matching manner, such as the positioning portion 15 can be designed as a groove or a through hole, and the corresponding positioning piece 2 can be selected as an elastic buckle, a protruding rib or a sliding block; by embedding the buckle / protruding rib / sliding block into the groove / through hole, or disengaging it, the position is locked and unlocked. The positioning piece 2 and the positioning portion 15 can be matched in a hook body matching manner, such as the positioning piece 2 can be designed as a clasp bent towards the second end of the locking wire member 11, and the positioning portion 15 is designed as a clasp opposite to the bending direction of the positioning piece 2; by hooking or separating the two opposite claps, the position of the locking wire member is positioned.

[0050] When the second end of the clamping wire component 1 is driven by external force to be in the wire loosening position, the clamping wire hole 141 has the maximum opening degree, and the cable can be freely inserted and pulled out. At this time, by engaging the positioning piece 2 with the positioning portion 15, the movement position of the locking wire member 11 can be limited without the need to continuously apply external force, so that the locking wire member 11 is fixed in the wire loosening position, facilitating the user to operate the cable insertion and pulling out with both hands.

[0051] When the clamping wire component 1 switches from the wire loosening position to the wire locking position, by applying force or mechanical energy to the second end of the locking wire member 11 in a predetermined operation range, the positioning piece 2 is separated from the positioning portion 15, and the elastic member is deformed under the action of the elastic force, so that the locking wire member 11 moves towards the connection section, and the opening degree of the clamping wire hole 141 decreases.

[0052] The shell 4 is also provided with a reinforcing sheet connected with the positioning piece 2 for increasing the strength of the positioning piece 2. For example, the reinforcing sheet can be a plastic reinforcing rib or a stainless steel sheet.

[0053] In some embodiments, the positioning piece 2 is provided with a first guide portion 17 near one end of the elastic member 12, and the first guide portion 17 is a slope structure. Among them, the slope of the slope structure is higher at the end close to the wire loosening position than at the end away from the wire loosening position. When the locking wire member 11 moves to the wire loosening position, the slope structure of the first guide portion 17 can guide the positioning piece 2 to engage with the positioning portion 15, avoiding the problem of jamming caused by alignment error, and ensuring that the positioning piece 2 and the positioning portion 15 are quickly and accurately engaged. During the movement of the locking wire member 11 from the wire loosening position to the wire locking position, the first guide portion 17 can assist the positioning piece 2 to smoothly separate from the positioning portion 15, reduce the mechanical impact or friction resistance in the instant of separation, and avoid wear of the components due to forced separation.

[0054] In some embodiments, a limiting piece 3 is arranged on the second end of the locking wire member 11, and the limiting piece 3 moves in cooperation with the second end of the locking wire member 11 to constrain the movement track of the locking wire member 11 and limit the stroke range of the locking wire member 11. In this regard, the limiting piece 3 can be directly formed by optimizing the structure of the second end of the locking wire member 11, such as bending the end of the second end into a triangular shape or a shape with a limiting protrusion, or directly arranging a limiting protrusion in the preset operation range of the second end, or designing the edge of a specific section as a structure with a limiting function, so as to naturally limit the maximum distance of the movement of the locking wire member 11 to the inside and outside of the shell 4. The limiting piece 3 can slide with the movement of the second end, and the maximum distance of the movement of the second end of the locking wire member 11 to the outside of the shell 4 and / or to the inside of the shell 4 is forced by the sliding path of the limiting piece 3.

[0055] More specifically, for the limiting piece 3 arranged in the preset operation range, the shape of the limiting piece 3 can be designed as a structure convenient for the user to apply force, such as a plane with anti-skid lines, an arc-shaped protrusion, or a groove suitable for finger pressing, etc. Such design enables the limiting piece 3 to serve as a force application point for user operation while realizing the functions of track constraint and stroke limitation, thereby improving the convenience and comfort of operation and facilitating the user to directly operate the second end.

[0056] In some possible implementation manners, the limiting piece 3 is provided with a first limiting portion 31, and the shell 4 is provided with a first matching portion 41, the first limiting portion 31 is located outside the first matching portion 41, and the stroke of the movement of the locking wire member 11 to the inside of the shell 4 is limited by the abutment of the first matching portion 41 against the first limiting portion 31, so as to avoid excessive rebound of the locking wire member 11 to cause insufficient opening of the wire clamping hole 141 and further cause the cable 5 to be unable to be inserted.

[0057] In some possible implementation manners, the limiting piece 3 is provided with a second limiting portion 32, and the shell 4 is provided with a second matching portion 42, the second matching portion 42 is located outside the second limiting portion 32, and the stroke of the movement of the locking wire member 11 to the outside of the shell 4 is limited by the abutment of the second matching portion 42 against the second limiting portion 32.

[0058] In some embodiments, the second matching portion 42 has a spacing with the wall surface of the second end, which provides an operation space for the user to operate the second end of the locking wire member 11 and also reserves a necessary movement gap for the disengagement action of the positioning portion 15 and the positioning piece 2. Since the second matching portion 42 and the positioning piece 2 are located on both sides of the locking wire member 11, when the user operates the limiting piece 3 on the second end to move towards the second matching portion 42, the locking wire member 11 is driven to move away from the positioning piece 2, so as to separate the positioning piece 2 from the positioning portion 15, thereby releasing the positioning constraint on the locking wire member 11, making the wire clamping member 1 exit the wire loosening state and switch to the wire locking state.

[0059] In some embodiments, the limiting member 3 is provided with an insulating member, more specifically, a plastic member is injected on the operable part of the limiting member 3, so that the wire clamping part 1 and the plastic member are injection molded as one part, and the end of the wire clamping part 1 is rubber-coated for insulation, making the product safer and more convenient to operate. The shape of the insulating member can be consistent with the shape of the limiting member 3, tightly fitted to the contour of the limiting member 3, and the rubber coating is shaped to maintain a compact structure; or it can be designed in a separate form according to the operation requirements, such as adding an arc-shaped protrusion, a non-slip pattern or a groove suitable for finger pressing on the operable part, which not only retains the insulation function, but also further optimizes the operation feel and force efficiency.

[0060] In some embodiments, a anti-falling member is provided between the insulating member and the limiting member 3 to enhance the stability of their connection, prevent the insulating member from separating from the limiting member 3 in a long-term operation or vibration environment, and ensure the long-term reliability of the insulation function and the operation feel. The specific form of the anti-falling member can be flexibly selected according to the connection requirements. It can be a mechanical engagement structure, such as a pre-set groove, protrusion or barb on the surface of the limiting member 3. When the insulating member is injection molded, the plastic material will fill into these structures, forming a physical engagement to prevent the insulating member from falling off; it can be a surface roughening treatment, such as roughening the surface of the limiting member 3 and the insulating member in contact, such as wire drawing, sandblasting or opening small patterns, to increase the frictional force between the two, limit the displacement of the insulating member by frictional force, and reduce the risk of falling off; it can also be a fitting structure, such as providing through holes or notches on the limiting member 3, allowing the plastic material to pass through these holes or notches during injection molding, forming an anchor connection, so that the insulating member and the limiting member 3 form a whole by mutual fitting, and the separation is structurally impossible.

[0061] In some embodiments, the limiting member 3 is provided with an abutting portion 35, and the shell 4 is provided with an opening 45. When the wire clamping part 1 is switched from the locked wire position to the loose wire position, the prying member 6 is guided to the prying force point through the opening 45 and the abutting portion 35, so that when the prying member 6 applies force to the prying force point, the wire clamping hole 141 expands. In this embodiment, the opening 45 of the shell 4 guides the prying member 6 to insert at a predetermined angle, and after the prying member 6 is inserted, its end will naturally fit the abutting portion 35 of the limiting member 3, ensuring that the force is directly transmitted to the limiting member, avoiding empty prying caused by force deviation, so as to ensure that the wire clamping hole 141 can be stably expanded to the required opening degree for unlocking.

[0062] To further improve the positioning accuracy and force exertion smoothness of the prying member 6, a second guide portion 33 can be additionally arranged on the abutting portion 35, and a third guide portion 34 is correspondingly arranged on the second matching portion 42. The two guide portions are usually designed as inclined surfaces or arc surfaces matching the shape of the prying member 6: the second guide portion 33 can assist the end of the prying member 6 to quickly fit the abutting portion 35, and the third guide portion 34 can correct the angle deviation during the insertion of the prying member 6. The cooperation of the two guide portions further reduces the operation difficulty and ensures the efficient and labor-saving prying action.

[0063] In some embodiments, the shell 4 is provided with a cable opening 43 corresponding to the position of the wire clamping hole 141, so that the cable 5 can be inserted into the wire clamping hole 141 through the cable opening 43.

[0064] In some embodiments, the inside of the shell 4 is provided with a conductive sheet 44, and the positioning section 122 is fixedly connected with the conductive sheet 44.

[0065] The overall working process of the above wiring device is as follows: (I) Wiring process When the locking member 11 is moved to the wire loosening position, the wire clamping hole 141 is opened, and the cable 5 is inserted. Specifically, when the limiting member 3 drives the locking member 11 to move away from the elastic member 12, the diameter of the wire clamping hole 141 is expanded, and the diameter of the movable hole 142 is reduced. At this time, the squeezing ring is in a compressed configuration, and the elastic potential energy is stored. When the positioning member 2 is engaged with the positioning portion 15 on the second end, the opening of the wire clamping hole 141 is in a constant state. At this time, the cable opening 43 corresponds to the wire clamping hole 141, and the cable 5 can be inserted into the wire clamping hole 141 through the cable opening 43.

[0066] After the cable 5 is inserted into the wire clamping hole 141, the locking member 11 is moved to the wire locking position to reduce the wire clamping hole 141 and clamp the cable 5. Specifically, the limiting member 3 is pressed manually or by a tool to move away from the positioning member 2, so that the positioning portion 15 on the limiting member 3 is disengaged from the positioning member 2. At this time, the position of the locking member 11 is no longer limited by the positioning member 2. The squeezing ring expands under its own elastic force, thereby driving the locking member 11 to move towards the connecting section 121. With the movement of the locking member 11, the opening of the wire clamping hole 141 gradually decreases. Finally, the cable 5 is clamped tightly under the cooperation of the locking member 11 and the positioning section 122, ensuring stable and reliable cable connection.

[0067] (II) Wire loosening process Before loosening the wire, the wire clamping hole 141 is in a state of clamping the cable 5 tightly. In order to facilitate the control of the opening of the wire clamping hole 141, Figure 3As shown, the prying member 6 (for example, a flat screwdriver) is inserted into the illustrated slot, and the casing 4 is pried outward with the edge of the cover on the casing as the fulcrum, driving the cable clamping member 1 to move outward, and the diameter of the cable clamping hole 141 is enlarged. During the movement, the positioning portion 15 of the cable clamping member 1 reestablishes the cooperation with the positioning member 2 inside the casing. When the positioning portion 15 of the cable clamping member 1 cooperates with the positioning member 2 on the casing, the cable clamping member 1 is positioned by the positioning member 2, at this time, the cable clamping hole 141 of the cable clamping member 1 is opened to a large enough opening, and the cable 5 can be pulled out, completing the cable loosening operation.
