Description

Technical Field

[0001] This utility model relates to the field of wiring device technology, specifically to a wiring device for intelligent building operations. Background Technology

[0002] Intelligent buildings, by integrating modern information technology, achieve automation of building equipment, convenient communication, and intelligent management, greatly improving building efficiency and user experience. During the wiring process in intelligent buildings, due to the complexity of system functions, multi-core cables typically require wiring operations, necessitating precise connection of each branch line. However, the traditional method of binding with insulating tape suffers from problems such as branches being tightly packed together and lacking space for dispersion, leading to signal interference between branches and affecting transmission quality. Furthermore, if cables are subjected to external force during wiring, the joints are easily separated, reducing the stability and reliability of the wiring system, necessitating improvement. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a wiring device for intelligent building operations, including a bottom shell and a cover plate. The cover plate is fixedly mounted on the upper end of the bottom shell by screws. Multiple wire clamping terminals are fixedly provided on the bottom surface inside the bottom shell. Through holes for cables to pass through are provided at both the left and right ends of the bottom shell. Anti-detachment components are fixedly provided on the outside of the through holes. The anti-detachment component includes an external threaded sleeve fixedly mounted on the bottom shell and an end cap threadedly connected to the external threaded sleeve. A ring is rotatably provided on the bottom surface inside the end cap. Multiple spaced rubber pressure plates are fixedly provided on the ring. A shrinking ring with a triangular cross-section is fixedly provided inside the external threaded sleeve. The rubber pressure plates and the shrinking ring are adapted to press the cable.

[0007] Furthermore, the inner diameter of the contraction ring gradually decreases from the outside to the inside.

[0008] Furthermore, the bottom surface inside the end cap is fixedly provided with a T-shaped annular slide rail, and the annular ring is slidably disposed within the annular slide rail.

[0009] Furthermore, the wire clamping terminal includes a wire clamping cavity with a rectangular frame structure, and at least two wire clamping bolts are threadedly connected to the upper end of the wire clamping cavity.

[0010] Furthermore, the inner end of the rubber pressure plate is fixedly provided with anti-slip protrusions.

[0011] Furthermore, the end cap has a through hole at its center for the cable to pass through.

[0012] (III) Technical Effects

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. This device is equipped with an anti-detachment component. The threaded sleeve is connected to the end cap by threads. With the internal shrink ring and rubber pressure plate, when the end cap is tightened, the rubber pressure plate slides down the inner wall of the shrink ring, which gradually decreases in diameter, and presses towards the center. The anti-slip protrusions tightly fit the cable, effectively preventing the connector from separating when the cable is pulled by external force, thus enhancing the stability of the wiring system.

[0015] 2. The wire clamping terminals adopt a rectangular frame structure with wire clamping bolts. Compared with binding with insulating tape, it can fix each branch of the multi-core cable in a different wire clamping cavity, so that the branches maintain a certain distance, reduce mutual interference, and improve signal transmission quality.

[0026] Combined with appendix Figure 1 To be continued Figure 6 A wiring device for intelligent building operations includes a base shell 1 and a cover plate 2. The cover plate 2 is fixed to the upper end of the base shell 1 by screws. Multiple wire clamping terminals 4 are fixedly provided on the bottom surface inside the base shell 1. Through holes 3 for cables to pass through are provided at both ends of the base shell 1. Anti-detachment components are fixedly provided on the outside of the through holes 3. The anti-detachment components include an external threaded sleeve 5 fixedly provided on the base shell 1 and an end cap 6 threadedly connected to the external threaded sleeve 5. The end cap 6 has a through hole 14 for cables to pass through at its center. A ring 7 is rotatably provided on the bottom surface inside the end cap 6. Multiple spaced rubber pressure plates 8 are fixedly provided on the ring 7. Anti-slip protrusions 13 are fixedly provided on the inner end of the rubber pressure plates 8. A shrink ring 9 with a triangular cross section is fixedly provided inside the external threaded sleeve 5. The rubber pressure plates 8 and the shrink ring 9 are adapted to press the cables. The inner diameter of the shrink ring 9 gradually decreases from the outside to the inside.

[0027] The bottom surface of the end cap 6 is fixedly provided with a T-shaped annular slide rail 10, and the annular ring 7 is slidably disposed within the annular slide rail 10. The wire terminal 4 includes a wire pressing cavity 11 with a rectangular frame structure, and at least two wire pressing bolts 12 are threadedly connected to the upper end of the wire pressing cavity 11.

[0028] The working principle of this utility model is as follows: This wiring device utilizes a threaded connection structure to achieve cooperation and adjustment between components. The anti-detachment component's shrink ring 9 and rubber pressure plate 8 compress and fix the cable, preventing external pulling from causing the cable to loosen. The wire clamping terminal 4 uses wire clamping bolts 12 to fix the branch wires of the multi-core cable within the wire clamping cavity 11, ensuring stable wiring and separation of branch wires, reducing signal interference. The cooperation between the annular slide 10 and the ring 7 inside the end cover 6 provides guidance for the rotation of the rubber pressure plate 8, making the compression action smoother.

[0029] The working process of this utility model is as follows:

[0030] 1. Cable insertion: The bottom shell 1 is fixed to the wall by bolts (bolt holes not shown) or adhesive (adhesive layer not shown). The multi-core cable is inserted into the through holes 3 at the left and right ends of the bottom shell 1, so that the cable passes through the through hole 14 in the center of the external threaded sleeve 5 and the end cap 6. The cable is located inside the multiple rubber pressure plates 8 on the ring 7 and inside the shrink ring 9.

[0031] 2. Install the end cap: Connect the end cap 6 to the external threaded sleeve 5 by thread. During the rotation of the end cap 6, the annular slide 10 on the bottom surface of the end cap 6 slides with the ring 7. The ring 7 will rotate with the rotation of the end cap 6. At the same time, the rubber pressure plate 8 will also rotate until the rubber pressure plate 8 contacts the shrink ring 9 and the cable bus 15. The rubber pressure plate 8 will then stop rotating and start sliding inward.

[0032] 3. Tighten the cable: As the end cap 6 is tightened, the rubber pressure plate 8 slides towards the center along the inner wall of the shrink ring 9, where the inner diameter gradually decreases. Because the rubber pressure plate 8 has a certain elasticity, the anti-slip protrusion 13 at its inner end will closely fit the surface of the cable, generating a squeezing force towards the center on the cable, thereby firmly fixing the cable and preventing it from coming out of the through hole 3 when pulled by external force.

[0033] 4. Branch line fixing: Place each branch line of the multi-core cable into the pressure cavity 11 of the pressure terminal 4. By rotating the pressure bolt 12, the pressure bolt 12 is pressed downward to fix the branch line firmly in the pressure cavity 11, ensuring that each branch line is separated from the others and reducing signal interference.

[0034] 5. Cover plate installation: After the cables are threaded and secured, the cover plate 2 is fixed to the upper end of the bottom shell 1 with screws to protect the internal cables and components, thus completing the installation of the entire wiring device.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
