[0008] This technical solution employs an externally threaded metal shell as the primary connecting and supporting component. Its threaded structure connects to the metal connector, which then clips into the electrical enclosure via a chuck, securing the entire structure. The chuck secures the externally threaded metal shell within the enclosure, ensuring a secure connection. The gasket acts as a buffer and seal, reducing direct pressure on the enclosure when the metal connector is tightened and improving the seal of the joint. The bulletproof inner shell enhances the strength and durability of the joint, preventing cracking due to external forces or prolonged use.

[0009] Preferably, the inner diameter area of ​​the metal connector is the same as the outer diameter area of ​​the externally threaded metal shell.

[0010] By adopting the above technical solution: the metal connector can be tightly fitted on the left side of the outer surface of the external threaded metal shell, ensuring the tightness and stability of the connection between the two, preventing loosening and displacement, helping to achieve a good sealing effect, reducing the impact of external factors on the internal, and being able to evenly transmit the tightening force, thereby enhancing the reliability of the connection.

[0012] By adopting the above technical solution: the threaded retractable outer sheath provides external protection and retractable functions, adapts to the bending and stretching of the line, and plays a certain mechanical protection role. The insulating skin plays an insulating role to prevent current leakage and ensure safe use. The outer protective skin enhances the overall protection performance and resists external physical damage. The inner protective skin further protects the internal line and reduces wear and damage. The rubber filling between the outer protective skin and the inner protective skin plays a buffering and pressure-resistant role, reducing the impact of external pressure on the line, while increasing the overall flexibility and preventing the line from bending.

[0013] Preferably, the area of ​​the through hole is equal to the inner diameter area of ​​the metal connector, and the threaded retractable outer sheath and the metal connector, the externally threaded metal shell and the interior of the electrical box body are in communication.

[0014] By adopting the above technical solution: the through-hole area is equal to the inner diameter area of ​​the metal connector, which ensures that the connecting wire can pass smoothly without being hindered by the small hole diameter, and plays the role of a line channel. In addition, the mutual cooperation of these components forms a continuous, unobstructed and protected line channel from the outside to the inside, ensuring the stability, safety and flexibility of the electrical connection.

[0015] Preferably, the right end of the connecting wire body passes through the threaded retractable outer protective skin, the external threaded metal shell, and the connecting hole groove in sequence and is located in the threading hole, and the wire body fixing screw is tightly pressed against the right end of the connecting wire body.

[0016] By adopting the above technical solution: the wire body fixing screws press the wire body tightly, and the connecting wire body is firmly fixed in the fixing block to prevent it from loosening or shifting, thereby ensuring the reliability and stability of the electrical connection. By working together with these accessories, the connecting wire body can be safely and accurately connected to the inside of the electrical box, realizing stable electrical transmission and function.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, the externally threaded metal shell is clamped to the electrical box body through a chuck, and then the metal connector is threadedly connected to the left part of the externally threaded metal shell, so that the gasket is in close contact with the left end face of the electrical box body, thereby achieving a tight connection between the externally threaded metal shell and the electrical box body and facilitating installation and disassembly, which is beneficial for maintenance and replacement. The bulletproof wire inner shell embedded in the inner wall of the metal connector enhances its own strength, prolongs its service life, reduces the possibility of cracking due to long-term use or external force, and improves the stability and safety of the electrical connection;

[0019] 2. In the present invention, the threaded retractable outer sheath can adapt to the bending and stretching of the connecting cable body, effectively preventing damage to the line caused by bending, and a multi-layer protective structure such as an insulating skin, an outer protective skin, and an inner protective skin is provided inside the retractable outer sheath, which can provide comprehensive physical protection for the connecting cable body and reduce damage to the line caused by external factors.

[0030] In this embodiment, the anti-cracking mounting structure 6 includes an externally threaded metal shell 61, the left part of the externally threaded metal shell 61 extends into the electrical box body 1 through the connecting hole groove 5 and is fixedly connected to the chuck 62, the right part of the outer surface of the externally threaded metal shell 61 is movably connected with a gasket 63, the right part of the outer surface of the externally threaded metal shell 61 is threaded and movably connected with a metal connecting head 64, the metal connecting head 64 is located on the right side of the gasket 63, and a bulletproof wire inner shell 65 is inlaid between the inner walls of the metal connecting head 64. The externally threaded metal shell 61 is clamped to the electrical box body 1 through the chuck 62 and the connecting hole groove 5, the gasket 63 is tightly attached to the left end face of the electrical box body 1 but not fixed, and the inner diameter area of ​​the metal connecting head 64 is the same as the outer diameter area of ​​the externally threaded metal shell 61.

[0031] Through the above scheme: the externally threaded metal shell 61 is clamped and fixed to the electrical box body 1 through the chuck 62 at its left end and the connecting hole groove 5, providing basic support and positioning for the entire connection structure, and the gasket 63 is sleeved on the right part of the outer surface of the externally threaded metal shell 61. When the metal connector 64 is tightened, the gasket 63 is in close contact with the left end face of the electrical box body 1, which plays a role in buffering and dispersing pressure, reducing the direct pressure on the electrical box body 1, and protecting the electrical box body 1 from damage. The metal connector 64 is movably connected to the right part of the outer surface of the externally threaded metal shell 61 through a thread. Since the inner diameter area of ​​the metal connector 64 is the same as the outer diameter area of ​​the externally threaded metal shell 61, the connection is tight, ensuring the stability and sealing of the connection. In addition, a bullet-proof wire inner shell 65 is inlaid between the inner walls of the metal connector 64 to enhance the strength and durability of the metal connector 64, reduce cracking and damage caused by external force or long-term use, thereby ensuring the reliability and stability of the entire connection structure, and through the synergistic effect of various components, the connection line has a certain anti-cracking performance.

[0032] In this embodiment, the anti-bending protection structure 7 includes a threaded retractable outer protective skin 71, which is fixedly connected to the left end of the metal connector 64. A through hole 72 is opened at the right end of the threaded retractable outer protective skin 71. The inner wall of the threaded retractable outer protective skin 71 is fixedly connected to an insulating skin 73. The inner wall of the insulating skin 73 is fixedly connected to an outer protective skin 74. The inner wall of the outer protective skin 74 is fixedly connected to an inner protective skin 75. Rubber 76 is filled between the outer protective skin 74 and the inner protective skin 75. The area of ​​the through hole 72 is equal to the inner diameter area of ​​the metal connector 64.

The wire body fixing screw 3 is tightly pressed against the right end of the connecting wire body 8.

[0033] Through the above scheme: First, the right end of the connecting wire body 8 is passed through the through hole 72 opened on the threaded retractable outer sheath 71, the external threaded metal shell 61, and the connecting hole groove 5 in sequence, and finally located in the threading hole 4. Since the area of ​​the through hole 72 is equal to the inner diameter area of ​​the metal connector 64, it is ensured that the connecting wire body 8 can pass through smoothly without obstruction, and the threaded retractable outer sheath 71 is fixedly connected to the metal connector 64. When the connecting wire body 8 is bent or stretched during use, the threaded retractable outer sheath 71 can be stretched and contracted accordingly, playing a role in protecting and adapting to the activities of the line. The insulating skin 73 inside the outer protective skin can prevent current leakage and ensure the safety of the wire body when in use. The outer protective skin 74 and the inner protective skin 75 enhance the physical protection of the connecting wire body 8, and the rubber 76 filled between the two plays a buffering and pressure-resistant role, reducing the damage of the connecting wire body 8 to the external force.

Therefore, under the coordinated protection of various components, the wire body can stably and safely achieve electrical connection and signal transmission.

[0034] It should be noted that the present invention is a bending-resistant and crack-resistant connecting wire. During use, the externally threaded metal shell 61 is first clamped to the electrical box body 1 through the chuck 62 to provide a solid foundation for the connection part and reduce the risk of cracking due to loose connection. Then the metal connector 64 is threadedly connected to the externally threaded metal shell 61 to achieve a tight connection. At the same time, the gasket 63 can be tightly attached to the left end face of the electrical box body 1, which can disperse the pressure on the connection part and play a buffering role, reducing the cracking caused by pressure concentration. The bulletproof wire inner shell 65 embedded in the inner wall of the metal connector 64 enhances its own strength and reduces the possibility of cracking. The metal connector 64 is fixed to the right end of the threaded retractable outer protective skin 71, and the threaded retractable outer protective skin 71 is retractable. It can expand and contract as the connecting wire body 8 bends, adapt to its bending shape, and reduce the restriction and damage of the outer protective skin on the connecting wire body 8. The insulating skin 73, outer protective skin 74, inner protective skin 75 and filled rubber 76 are fixed in sequence from the outside to the inside of the threaded retractable outer protective skin 71, which can provide multi-layer protection and buffering for the connecting wire body 8 and enhance its anti-bending ability. Finally, the connecting wire body 8 is passed through each protective structure in turn, and finally the right end of the connecting wire body 8 is pressed tightly into the wire hole 4 opened on the fixing block 2 by the wire body fixing screw 3 to ensure that the connecting wire body 8 will not loosen or shift. Therefore, under the coordinated action of various components, the anti-cracking and anti-bending protection of the connecting wire body 8 is achieved, and the stability and safety of the connecting wire body 8 during use are guaranteed.
