[0023] Specific implementation examples are given below.
[0024] like Figures 1 to 4 As shown, a double-insulated electronic wire according to an embodiment of the present invention includes a copper wire 1, an inner sheath 2 fixedly connected to the side wall of the copper wire 1; support strips 4 fixedly connected to the side wall of the inner sheath 2, and multiple support strips 4 are arranged in a circumferential array; connecting strips 5 are fixedly connected between the multiple support strips 4, and the multiple connecting strips 5 are correspondingly arranged; an outer sheath 3 is fixedly connected to the side wall of the support strips 4 and the connecting strips 5; a sealing joint 6 is provided at the end of the copper wire 1, and the size of the sealing joint 6 corresponds to the size of the outer sheath 3; a wiring hole 8 is opened inside the sealing joint 6, and the wiring hole 8 corresponds to the size of the copper wire 1; an installation groove is opened at the end of the sealing joint 6 near the copper wire 1, and the installation groove corresponds to the size of the outer sheath 3; a junction box 16 is provided at the end of the sealing joint 6 away from the copper wire 1; a plug 17 is fixedly connected to the end of the junction box 16 away from the copper wire 1; during operation, the operator can use the installation groove opened on the sealing joint 6 corresponding to the outer sheath 3 to fit the sealing joint 6 at the end of the double-insulated electronic wire, and let the copper wire 1 pass through the sealing joint 16. The wiring hole 8 inside the connector 6 completes the connection between the sealed connector 6 and the copper wire 1, and subsequently the connection between the sealed connector 6 and the junction box 16. During daily operation, whenever the electronic wire needs to be bent, the multiple support bars 4 arranged in a circumferential array and the multiple corresponding connecting bars 5 can be bent freely. Whenever the double-insulated electronic wire is cut by a sharp object, the support bars 4 and connecting bars 5 can protect the inner sheath 2 after the outer sheath 3 is damaged, preventing the sharp object from damaging the inner sheath 2, thereby maintaining the stable operation of the copper wire 1. The plug 17 plays a conductive role. This step, by setting the sealed connector 6 and wiring hole 8 to connect the copper wire 1 and the junction box 16, improves the flexibility and safety of the double-insulated electronic wire. By setting the support bars 4 and connecting bars 5 to provide additional protection for the copper wire 1, it is beneficial to avoid the continuous damage of the inner sheath 2 and outer sheath 3 by sharp objects, which would affect the copper wire 1, and further enhances the stability of the double-insulated electronic wire.
[0025] like Figure 2 and Figure 4As shown, a fixing groove 7 is provided on the side wall of the sealing joint 6; a first fixing block 10 is provided on the side wall of the sealing joint 6, and a first groove 13 and a second groove 14 are provided on the side wall of the first fixing block 10; a first fixing ring 11 is provided inside the first groove 13, and a second fixing ring 12 is provided inside the second groove 14, with the first fixing ring 11 corresponding to the size of the first groove 13 and the second fixing ring 12 corresponding to the size of the second groove 14; an installation ring is fixedly connected inside the first fixing block 10, and the installation ring is positioned and sized to correspond to the fixing groove 7; during operation, after the worker completes the connection between the copper wire 1 and the sealing joint 6, the first fixing block 10 can be fitted onto the side wall of the sealing joint 6 to further complete the stable connection between the sealing joint 6 and the copper wire 1. During the process, the worker should fit the first fixing block 10 onto the side wall of the sealing joint 6 until the first fixing block... Once the mounting ring 10, which is internally fixed, enters the fixing groove 7 on the surface of the sealing joint 6, the assembly is complete. After assembly, the worker can install the first fixing ring 11 inside the first recess 13 and the second fixing ring 12 inside the second recess 14. After the first fixing ring 11 and the second fixing ring 12 are installed, they can apply stress to the first fixing block 10 and the sealing joint 6 through their own elasticity, thereby making the connection between the sealing joint 6 and the first fixing block 10 tighter. This step, by setting the first fixing ring 11 and the second fixing ring 12 to apply elasticity to the sealing joint 6 and the first fixing block 10, makes the connection between the sealing joint 6 and the first fixing block 10 tighter, which helps to prevent the sealing joint 6 from separating from the first fixing block 10 and from the outer sheath 3, improves the stability of the double-layer insulated electronic wire, and helps to extend its service life.
[0026] like Figure 4 As shown, a sealing groove 9 is provided at the end of the sealing joint 6 away from the outer casing 3, and two sealing grooves 9 are arranged in parallel; a rubber ring 20 is provided inside the two sealing grooves 9; sealing grooves 9 are provided inside the second groove 14 and the junction box 16, and multiple sealing grooves 9 are arranged to correspond to the size of the rubber ring 20; during operation, the operator can install the rubber ring 20 between the junction box 16 and the sealing joint 6 to seal the connection between the junction box 16 and the sealing joint 6, and can install the rubber ring 20 between the sealing joint 6 and the first fixing block 10 to seal the connection between the sealing joint 6 and the first fixing block 10. A seal is applied to the connection of the fixing block 10. During the process, before the sealing joint 6 and the first fixing block 10 are installed, the workers can install rubber rings 20 inside the two sealing grooves 9 opened on the surface of the sealing joint 6. After the installation is completed, the workers can install the sealing joint 6 and the first fixing block 10, as well as the outer sheath 3 and the junction box 16. This step applies a seal to the connection of the double-insulated electronic wire by setting the rubber rings 20, thereby isolating the water source and preventing rainwater from entering the interior of the double-insulated electronic wire, thus improving the stability of the double-insulated electronic wire.
[0027] like Figure 4 As shown, a second fixing block 18 is provided on the side wall of the plug 17, and the two second fixing blocks 18 are arranged in parallel; a connecting block 19 is fixedly connected between the two second fixing blocks 18; a groove is provided inside the junction box 16, and the groove is set to correspond to the size of the second fixing block 18 and the connecting block 19; during operation, the second fixing block 18 and the connecting block 19 located on the side walls of the two plugs 17 can provide support for the two plugs 17 by themselves. Whenever it is necessary to plug or unplug the plug 17, the second fixing block 18 and the connecting block 19 can provide support for the plug 17 by means of the restriction of the groove opened inside the junction box 16; this step, by setting the second fixing block 18 and the connecting block 19 to limit the plug 17, helps to prevent the plug 17 from tilting, improves the durability of the double-insulated electronic wire, and helps to extend the service life of the double-insulated electronic wire.
[0028] like Figure 4 As shown, a sealing ring 15 is fixed to the side wall of the first fixing block 10 away from the outer sheath 3, and the sealing ring 15 is positioned corresponding to the junction box 16. During operation, whenever the operator installs the sealing connector 6 inside the junction box 16, the sealing ring 15 at the end of the first fixing block 10 will come into close contact with the junction box 16, thereby sealing the connection between the first fixing block 10 and the junction box 16. This step, by setting the sealing ring 15 to seal the connection between the junction box 16 and the first fixing block 10, expands the contact area at the connection between the first fixing block 10 and the junction box 16, which helps to prevent the first fixing block 10 from detaching from the sealing connector 6, and improves the flexibility and durability of the double-insulated electronic wire.
[0029] like Figures 1 to 3 As shown, a filler is provided between the inner sheath 2 and the outer sheath 3, and the filler is provided corresponding to the support strip 4 and the connecting strip 5. During operation, the filler between the inner sheath 2 and the outer sheath 3 can fill the gap between the support strip 4 and the connecting strip 5 by itself. This step solves the problem of surface wrinkles of the double-insulated electronic wire by providing a filler between the inner sheath 2 and the outer sheath 3 to fill the gap between the support strip 4 and the connecting strip 5, which helps to strengthen the protective ability of the support strip 4 and the connecting strip 5 and further improves the durability of the double-insulated electronic wire.
[0030] like Figure 1 As shown, anti-slip grooves are provided on the side wall of the junction box 16, and multiple anti-slip grooves are arranged in a linear array. During operation, the operator can use the anti-slip grooves on the side wall of the junction box 16 to achieve stable insertion and removal. This step, by setting anti-slip grooves, increases the friction coefficient of the junction box 16, which helps to avoid slippage and improves the applicability of the double-insulated electronic wire.
[0031] During operation, workers can use the mounting groove corresponding to the outer sheath 3 of the sealing connector 6 to install the sealing connector 6 onto the end of the double-insulated electronic wire, and then let the copper wire 1 pass through the wiring hole 8 inside the sealing connector 6, thereby completing the connection between the sealing connector 6 and the copper wire 1, and subsequently the connection between the sealing connector 6 and the junction box 16. In daily work, whenever the electronic wire needs to be bent, multiple support bars 4 arranged in a circumferential array and multiple corresponding connecting bars 5 can be bent freely. When the double-insulated electronic wire is cut by a sharp object, the support bars 4 and connecting bars 5 can provide protection for the inner sheath 2 after the outer sheath 3 is damaged, preventing the sharp object from damaging the inner sheath 2, thus maintaining the stable operation of the copper wire 1. The plug 17 serves as a conductor. After the worker completes the connection between the copper wire 1 and the sealing connector 6, the first fixing block 10 can be fitted onto the side wall of the sealing connector 6 to further stabilize the connection between the sealing connector 6 and the copper wire 1. During the process, the worker should fit the first fixing block 10 onto the side wall of the sealing connector 6 until the mounting ring fixed inside the first fixing block 10 enters the fixing groove 7 opened on the surface of the sealing connector 6. After fitting, the worker can install the first fixing ring 11 inside the first recess 13 and the second fixing ring 12 inside the second recess 14. After the first fixing ring 11 and the second fixing ring 12 are installed, the first fixing block 10 and the sealing connector 6 can be bonded by their own elasticity. Stress, thereby making the connection between the sealing joint 6 and the first fixing block 10 tighter. Workers can install a rubber ring 20 between the junction box 16 and the sealing joint 6 to seal the connection. Similarly, a rubber ring 20 can be installed between the sealing joint 6 and the first fixing block 10 to seal the connection. During the process, before installing the sealing joint 6 and the first fixing block 10, workers can install the rubber ring 20 inside the two sealing grooves 9 opened on the surface of the sealing joint 6. After installation, workers can install the sealing joint 6 and the first fixing block 10, as well as the outer sheath 3 and the junction box 16. The second fixing block 10 is located on the side wall of the two plugs 17. The fixing block 18 and the connecting block 19 can provide support for the two plugs 17 by themselves. Whenever the plugs 17 need to be inserted or removed, the second fixing block 18 and the connecting block 19 can provide support for the plugs 17 by means of the grooves opened inside the junction box 16. Whenever the operator installs the sealing connector 6 inside the junction box 16, the sealing ring 15 located at the end of the first fixing block 10 will come into close contact with the junction box 16, thereby sealing the connection between the first fixing block 10 and the junction box 16. The filler between the inner skin 2 and the outer skin 3 can fill the gap between the support strip 4 and the connecting strip 5 by itself. During the process of inserting or removing the junction box 16, the operator can achieve a stable insertion and removal action by means of the anti-slip grooves opened on the side wall of the junction box 16.
