Description

Technical Field

[0001] This invention relates to the field of power fittings technology, and more specifically, to a snap-fit ​​cable fixing fitting connection structure. Background Technology

[0002] In the installation and maintenance of power systems, cable fixing hardware is a key component used to support and fix cables, preventing them from shifting, wearing, or being damaged due to their own weight, thermal expansion and contraction, or electromagnetic forces. Traditional cable fixing hardware usually adopts a split structure (such as a clamp structure consisting of a first clamp and a second clamp), which is connected and locked by fasteners such as bolts and nuts.

[0003] However, existing split-type cable fixing hardware has the following technical problems in practical applications: 1) Traditional structures often rely on external tools such as wrenches to tighten or loosen bolts, which is cumbersome and time-consuming, especially in high-altitude operations or environments with limited space, significantly reducing installation and maintenance efficiency. 2) Some quick-release structures only achieve single-point locking, resulting in insufficient overall structural stability and reliability, making them prone to accidental loosening due to vibration or other reasons; while high-reliability multi-point locking structures are often complex to operate, making it difficult to achieve rapid locking and simultaneous unlocking.

[0004] Therefore, there is an urgent need to provide a cable fixing hardware connection structure that is reasonably designed, easy to operate, and has reliable locking, in order to solve the above-mentioned technical problems. Summary of the Invention

The fixed block slide cavity is connected to the arc-shaped cavity. The fixed block is slidably disposed in the fixed block slide cavity and is fixedly connected to the arc-shaped insert plate. The fixed block is connected to the fixed block slide cavity through the second elastic element. When there is no external force, the second elastic element drives the arc-shaped insert plate to be inserted into the slot.

[0010] Optionally, the locking and releasing assembly includes a U-shaped locking rod slide cavity, a U-shaped locking rod, an unlocking button, a third elastic element, an end notch, an engagement groove, and an engagement block; The U-shaped locking rod slide cavity is opened at the other end of the first wire clamp seat and the second wire clamp seat and communicates with the slot. The U-shaped locking rod is slidably disposed in the U-shaped locking rod slide cavity, and the unlocking button is fixed to the outer end of the U-shaped locking rod. The end notch is opened at one end of the arc-shaped insert plate near the slot, the engagement groove is located at the end notch, and the engagement block is located at the end of the U-shaped locking rod and cooperates with the engagement groove. The third elastic element is located in the sliding cavity of the U-shaped locking rod and provides elastic support for the U-shaped locking rod. When there is no external force, the locking block is inserted into the locking groove.

[0011] Optionally, the synchronous unlocking component includes a spindle, a knob, a screw sleeve, a positioning block, a displacement port, an engagement protrusion, a rope channel, and a pull rope; The mandrel is located inside the outer cylinder and is rotatably connected to both ends of the outer cylinder, and the knob is fixed to the end of the mandrel; The threaded sleeve is threaded onto the mandrel, and the positioning block is fixed to the threaded sleeve and slides out from the displacement port of the outer cylinder; The engagement protrusion is located at one end opposite to the second bushing and the first bushing, and the positioning block has an engagement groove that mates with the engagement protrusion.

[0016] The snap-fit ​​cable fixing hardware connection structure provided by this invention has the following beneficial effects: By setting up a plug-in component, a locking and releasing component, and a synchronous unlocking component, rapid locking and coordinated release are achieved after the first wire clamp and the second wire clamp are closed.

[0017] Specifically: After the plug-in assembly is plugged in and locked by the locking and releasing assembly, the synchronous unlocking assembly can simultaneously fix the second bushing and the first bushing, that is, lock both ends of the first wire clamp and the second wire clamp, which is highly reliable. When unlocking is required, press the locking release component to release the lock on the plug-in component. Then, by operating the synchronous unlock component, the plug-in state of the plug-in component can be released simultaneously, and the fixation of the first and second bushings can be released at the same time, so that the first and second wire clamps can rotate freely around the outer cylinder.

[0018] This structure combines the unlocking action with the rotation release through a linkage design, significantly improving operational efficiency and convenience.

Detailed Implementation

[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] like Figures 1-10 As shown, an embodiment of the present invention provides a snap-fit ​​cable fixing hardware connection structure, including a first wire clamp 1 and a second wire clamp 2 that are fitted together. One end of the first wire clamp 1 and the second wire clamp 2 are respectively connected and fixed to a first bushing 5 and a second bushing 3 via a second connecting block 6 and a first connecting block 4. The first bushing 5 and the second bushing 3 are rotatably mounted on the outer cylinder 30; it also includes: The plug-in assembly is provided in the first wire clamp 1 and the second wire clamp 2 respectively, and the other end of the first wire clamp 1 and the second wire clamp 2 is provided with a locking and releasing assembly 8 for locking and fixing the plug-in assembly. A synchronous unlocking component is installed on the outer cylinder 30. When the plugging component is in the plugging state, the synchronous unlocking component is used to simultaneously fix the second bushing 3 and the first bushing 5. The synchronous unlocking component is also used to control the plugging component to release the plugging state, and at the same time release the fixing state of the second bushing 3 and the first bushing 5.

[0026] This invention achieves rapid locking and coordinated release after the first wire clamp 1 and the second wire clamp 2 are closed by setting up a plug-in component, a locking and releasing component 8, and a synchronous unlocking component. Specifically: after the plug-in component completes the plug-in and is locked by the locking and releasing component 8, the synchronous unlocking component can simultaneously fix the second bushing 3 and the first bushing 5, that is, both ends of the first wire clamp 1 and the second wire clamp 2 are locked, resulting in high reliability. When unlocking is required, press the locking release component 8 to release the lock on the plug-in component. Then, by operating the synchronous unlocking component, the plug-in state of the plug-in component can be released simultaneously, and the fixation of the first bushing 5 and the second bushing 3 can be released at the same time, so that the first wire clamp seat 1 and the second wire clamp seat 2 can rotate freely around the outer cylinder 30.

[0027] This structure combines the unlocking action with the rotation release through a linkage design, significantly improving operational efficiency and convenience.

[0028] like Figure 1As shown, in one embodiment, the first wire clamp 1 and the second wire clamp 2 are semi-circular ring structures that are arranged opposite to each other and cooperate with each other. Multiple elastic support ribs 7 are evenly distributed and fixed on the inner walls of the first wire clamp 1 and the second wire clamp 2. The elastic support ribs 7 can provide elastic support for the cable and protect the cable from damage.

[0029] The second connecting block 6 and the first connecting block 4 are located on different sides of one end of the first wire clamp 1 and the second wire clamp 2, thus avoiding interference between the second bushing 3 and the first bushing 5, and allowing the second bushing 3 and the first bushing 5 to be coaxially installed on the outer cylinder 30, forming a reliable hinge structure.

[0030] The semi-circular ring structure formed by the cooperation of the first wire clamp 1 and the second wire clamp 2, combined with the elastic support ribs 7 evenly distributed on the inner wall, enables multi-point flexible contact and elastic buffering of the cable. This effectively disperses clamping stress while absorbing vibration energy, thereby avoiding damage to the cable outer sheath and improving the stability of the fixation. At the same time, by misaligning the second connecting block 6 and the first connecting block 4 on different sides, the spatial interference between the second bushing 3 and the first bushing 5 is cleverly avoided, ensuring that the two can be smoothly coaxially installed on the outer cylinder 30 to form a reliable hinge center. This not only ensures the flexibility and synchronization of the rotation of the first wire clamp 1 and the second wire clamp 2 around the axis, but also optimizes the compactness of the overall structure, providing the necessary spatial basis for subsequent linkage unlocking operations.

[0031] To broaden the applicability of this fitting to cables of different diameters, a removable arc-shaped pad (not shown) is provided on the inner side of the elastic support rib 7. This pad is made of flexible conductive rubber or engineering plastic, and its inner arc surface has anti-slip textures. Multiple hooks are provided on the back of the pad, forming a quick-release structure with corresponding slots on the elastic support rib 7. Users can select a pad of appropriate thickness (such as 2mm, 5mm, or 8mm thickness series) according to the actual outer diameter of the cable, allowing the fitting to tightly clamp the cable without damaging the insulation layer. Simultaneously, a conductive layer can be provided between the pad and the elastic support rib 7 to ensure the continuity of the grounding path.

[0032] This design allows a single set of fittings to cover the range of commonly used cable diameters, reducing inventory specifications and improving the product's versatility and economy.

[0033] like Figures 6-7As shown, in one embodiment, the insertion components in the first wire clamp 1 and the second wire clamp 2 are arranged opposite each other and located on different sides, which can form a reciprocating insertion and fixing effect, improving its reliability. The insertion component includes an arc-shaped cavity 15 opened in the first wire clamp 1 and the second wire clamp 2. An arc-shaped insert plate 16 is slidably arranged in the arc-shaped cavity 15. The other end of the first wire clamp 1 and the second wire clamp 2 is correspondingly provided with a slot 20 for inserting the arc-shaped insert plate 16. The first wire clamp 1 and the second wire clamp 2 are also provided with a fixing block slide cavity 17 communicating with the arc-shaped cavity 15. A fixing block 18 fixedly connected to the arc-shaped insert plate 16 is slidably arranged in the fixing block slide cavity 17. The fixing block 18 is also connected to one end of the fixing block slide cavity 17 through a second elastic member 19. When there is no external force, the second elastic member 19 is used to make the arc-shaped insert plate 16 insert into the slot 20.

[0034] By setting the plug-in components opposite and staggered in the first wire clamp 1 and the second wire clamp 2, a stable opposing plug-in fixing structure is formed by the cooperation of the arc-shaped cavity 15, the arc-shaped insert plate 16 and the slot 20, which significantly improves the torsional strength and connection reliability after closure. At the same time, with the help of the automatic reset drive mechanism composed of the fixed block sliding cavity 17, the fixed block 18 and the second elastic element 19, the arc-shaped insert plate 16 can be automatically inserted into the slot 20 to complete self-locking without external force. This design not only simplifies the installation steps and completes the initial locking without the need for additional tools, but also eliminates the mating gap through the continuous elastic resistance of the second elastic element 19, effectively preventing the device from accidentally loosening in a vibration environment.

[0035] like Figures 8-10 As shown, in one embodiment, the locking and releasing assembly 8 includes a U-shaped locking rod slide cavity 25 located at the other end of the first wire clamp 1 and the second wire clamp 2 and communicating with the slot 20. A U-shaped locking rod 24 is slidably disposed within the U-shaped locking rod slide cavity 25. An unlocking button 23 is fixed to the outer end of the U-shaped locking rod 24. An end notch 27 is provided on the side of the arc-shaped insert 16 near the slot 20 away from the unlocking button 23. An engagement groove 28 is provided on the end of the end notch 27 near the unlocking button 23. The U-shaped locking... The end of the lever 24 away from the unlock button 23 is provided with a locking block 29 that cooperates with the locking groove 28. The U-shaped locking lever slide cavity 25 is also provided with a third elastic element 26 for elastic support of the U-shaped locking lever 24. When there is no external force, after the arc-shaped insert plate 16 is inserted into the slot 20, the locking block 29 at the end of the U-shaped locking lever 24 is inserted into the locking groove 28 under the elastic force of the third elastic element 26. When it is necessary to unlock, the locking block 29 can be separated from the locking groove 28 by pressing the unlock button 23.

[0036] Through the linkage between the locking and releasing assembly 8 and the arc-shaped insert 16, a double-safety locking and convenient release function is achieved: when the arc-shaped insert 16 is inserted into the slot 20, the U-shaped locking rod 24, under the elastic force of the third elastic element 26, causes the locking block 29 at its end to automatically engage in the locking groove 28 of the arc-shaped insert 16, forming a mechanical limit, effectively preventing the arc-shaped insert 16 from accidentally slipping out, and significantly improving the vibration resistance and reliability of the connection structure; when unlocking is required, simply press the unlock button 23 to drive the U-shaped locking rod 24 to overcome the elastic force of the elastic element and move it, causing the locking block 29 to disengage from the locking groove 28. The operation is simple and quick, and the entire locking and releasing process does not require the use of external tools, greatly improving maintenance efficiency.

[0037] To prevent the unlock button 23 from being accidentally released due to vibration or accidental contact, this embodiment also includes an anti-misoperation structure on the unlock button 23. Specifically, a radial sliding hole is provided on the side of the unlock button 23, through which a locking pin (not shown) is slidably disposed, and the outer end of the locking pin is provided with a toggle handle. Locking blind holes that cooperate with the locking pin are provided at corresponding positions on the end faces of the first wire clamp 1 and the second wire clamp 2. In the locked state, the locking pin is inserted into the locking blind hole under the action of an internal small spring, preventing the unlock button 23 from being pressed. During operation, the locking pin must first be moved out of the locking blind hole with a finger before the unlock button 23 can be pressed.

[0038] In addition, red and green locking status indicator pieces are provided on the surface of the unlock button 23 and at the corresponding positions of the first wire clamp 1 and the second wire clamp 2, respectively. When the plug-in component is fully locked, the green indicator piece is exposed; when the locking release component is released, the red indicator piece is exposed, which makes it easy for high-altitude workers to remotely confirm the status.

[0039] like Figures 1-7As shown, in one embodiment, the synchronous unlocking component includes a spindle 13 located inside the outer cylinder 30. The spindle 13 is rotatably connected to both ends of the outer cylinder 30, preferably with damped rotational connection to prevent the spindle 13 from rotating on its own and improve reliability. A knob 12 is also fixed to the end of the spindle 13. Two threaded sleeves (not shown) are threadedly connected to the spindle 13. A positioning block 10 is fixed on the threaded sleeve and slides out from the displacement port 11 opened on the side wall of the outer cylinder 30. Preferably, the positioning block 10 and the displacement port 11 are in a damped sliding connection to further improve the stability of the spindle 13. The second bushing 3 and the first bushing 5 have an engagement protrusion 9 at their opposite ends. The positioning block 10 has an engagement groove that mates with the engagement protrusion 9. The spindle 13 has two external threads with opposite directions, which are threadedly engaged with the two threaded sleeves respectively. When the spindle 13 rotates, the two positioning blocks 10 move closer or further away from each other, so that the two positioning blocks 10 can simultaneously engage or release the second bushing 3 and the first bushing 5. The first connecting block 4 and the second connecting block 6 are also provided with a rope channel 22. One end of the rope channel 22 is connected to the arc-shaped cavity 15, and the other end of the rope channel 22 is connected to the inner cavity of the outer cylinder 30. The end of the arc-shaped insert plate 16 away from the slot 20 is fixedly connected to the spindle 13 by a pull rope 21. Alternatively, a rope wheel (not shown) can be provided on the spindle 13, so that the pull rope 21 can be wound around the rope wheel. There is no limitation.

[0040] Furthermore, a first elastic element 14 is also sleeved on the mandrel 13 between the two threaded sleeves. The first elastic element 14 is used to elastically support the threaded sleeves, further improving the stability of the movement of the threaded sleeves.

[0041] In application, when the arc-shaped insert 16 is inserted into the slot 20, rotating the spindle 13 moves the two positioning blocks 10, which abut against the engaging protrusions 9, simultaneously fixing the second bushing 3 and the first bushing 5. At this time, the spindle 13 is in a released state relative to the pull rope 21, without affecting the arc-shaped insert 16. When the arc-shaped insert 16 is released from the insertion state, rotating the spindle 13 in the opposite direction separates the two positioning blocks 10 from the engaging protrusions 9, and simultaneously rewinds the pull rope 21, causing the arc-shaped insert 16 to separate from the slot 20. Furthermore, note that the winding state of the two pull ropes 21 and the spindle 13 is adapted to ensure that the rotation of the spindle 13 simultaneously releases and rewinds the two pull ropes 21.

[0042] Through the synchronized unlocking component's linkage design, a multi-point locking and coordinated release function is achieved, significantly improving operational efficiency and structural reliability. Specifically, utilizing the threaded engagement between the mandrel 13 and the threaded sleeve, and the stable support of the first elastic element 14, rotating the knob 12 drives the two positioning blocks 10 to move synchronously, causing their meshing grooves to precisely engage or disengage with the meshing protrusions 9 of the second bushing 3 and the first bushing 5, thereby simultaneously braking or releasing the bushings at both ends, avoiding the tediousness of traditional point-by-point operation; simultaneously, by pulling the rope 2... The winding connection between the spindle 13 and the positioning block 10 releases the brake, and the rotation of the spindle 13 automatically retracts the pull rope 21, directly driving the arc-shaped insert plate 16 out of the slot 20. This integrates the two actions of "releasing the bushing fixation" and "unlocking the plug-in assembly" into a single operation, greatly simplifying the disassembly process. In addition, the damped rotation spindle 13 and the damped sliding positioning block 10 design effectively prevents accidental loosening under vibration, while the hidden layout of the rope channel 22 and the pull rope 21 protects the transmission components from external interference.

[0043] The above embodiments of the present invention provide a snap-fit ​​cable fixing hardware connection structure, the working principle of which is as follows: The first wire clamp 1 and the second wire clamp 2 are rotatably connected to the outer cylinder 30 via the first bushing 5 and the second bushing 3, forming a hinged structure. The elastic support ribs 7 provided on the inner walls of both provide elastic clamping and protection for the cable. At the mating ends of the two wire clamps, the arc-shaped insert plate 16 in the plug assembly automatically inserts into the corresponding slot 20 under the elastic force of the second elastic element 19. At the same time, the U-shaped locking rod 24 in the locking and releasing assembly 8, under the action of its third elastic element 26, causes the locking block 29 at its end to engage in the locking groove 28 of the arc-shaped insert plate 16, thereby completing the mechanical locking of the plug end and keeping the wire clamps in a stable closed state.

[0044] When unlocking is required, firstly, pressing the unlock button 23 causes the U-shaped locking lever 24 to compress the third elastic element 26, completely disengaging the engaging block 29 from the engaging groove 28. Then, the synchronous unlocking assembly, controlled by the spindle 13, is operated. When the knob 12 rotates clockwise, it drives the spindle 13 to rotate, causing the two positioning blocks 10 on it to move towards each other along the displacement port 11 until they engage with the engaging protrusions 9 on the first bushing 5 and the second bushing 3, thus synchronously locking the rotation of the two bushings. At this time, the pull rope 21 connecting the spindle 13 to the arc-shaped insert 16 is in a released or slack state. When unlocking is required, rotating the spindle 13 in the reverse direction causes the two positioning blocks 10 to separate from the engaging protrusions 9, releasing the lock on the bushings. During this process, the spindle 13 synchronously retracts the pull rope 21, pulling the arc-shaped insert 16 to overcome the elastic force of the second elastic element 19 and exit from the slot 20, thus releasing the insertion state.

[0045] In summary, this structure can control the locking and disengagement of the bushing by rotating a single spindle 13. The entire mechanism achieves reliable maintenance and rapid, synchronous release of the cable fixing hardware connection.
