[0029] Example 2: As Figures 8-10As shown, a wiring device for quick connection of flexible wires according to an embodiment of the present invention includes an insulating housing 1, on which two insertion ports 11 for inserting flexible wires are formed. A piercing element 2, made of metal, is provided inside the insulating housing 1.

[0030] This wiring device has a compact structure and is specifically designed for waterproof connections of flexible wires. It provides a double seal for the inserted flexible wire through a sealing ring and insulating sealant. It can be used for waterproof connections of both round and flat flexible wires. This wiring device has excellent waterproof and insulation performance and low overall cost. It can be widely used for quick wiring of indoor, outdoor and underground flexible wires, as well as underwater connections of low-voltage flexible round wires.

[0031] In practical use, the description is based on the accompanying drawings for the purpose of understanding this utility model;

[0032] Figure 7 , Figure 10The diagrams show the usage states of Examples 1 and 2, respectively. During use, depending on the sealing requirements, it is optional to inject insulating sealant 5. For scenarios with high sealing requirements, insulating sealant 5 needs to be injected beforehand. The sealing ring 3 and the insulating sealant 5 provide a double seal for the inserted flexible wire. The cut flexible wire is directly inserted into the insertion port 11. During this process, there is no need to press the release ring 41. The inward thrust of the flexible wire causes multiple elastic fins 431 to expand elastically, allowing the flexible wire to be inserted smoothly. After insertion, the contraction force of the multiple elastic fins 431 acts as a stop for the flexible wire, making the wiring process very easy, secure, and preventing loosening, resulting in good sealing. When it is necessary to remove the flexible wire, press the release ring 41 to slide it relative to the guide ring 42 towards the positioning ring 44. This allows the multiple elastic fins 431 to expand further, at which point the connected flexible wire can be easily pulled out.

[0033] See Figure 10 When the two flexible wires are inserted into the bottom of the two plug ports 11 respectively, the insulating sealant 5 will automatically overflow a portion, thereby achieving a better sealing effect.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
