The flame-retardant insulated wire structure 100 provided in one embodiment of the present invention includes a conductor 10, an insulating layer 20, a flame-retardant layer 30 and an insulating terminal 40. The conductor 10 is used for current transmission; the insulating layer 20 covers the conductor 10, and the insulating layer is used for electrical insulation; the flame-retardant layer 30 covers the insulating layer 20, and the flame-retardant layer 30 is used to slow down the spread of flames; the insulating terminal 40 is detachably connected to the conductor 10; wherein the insulating terminal 40 can be used to connect to the conductor 10 so that the conductor 10 can be connected to peripheral components.

[0032] Regarding the conductor 10 mentioned above, the conductor 10 of the insulated wire is mainly used to transmit current. The conductor 10 is the core part of the insulated wire and carries the transmission of current. The conductor 10 is usually made of materials with good electrical conductivity such as copper or aluminum. Among them, the conductor 10 transmits electrical energy from the power source to the load device through its good electrical conductivity, supplying the required electrical energy. In addition, the resistance of the conductor 10 has a certain influence on the performance of the circuit. Lower resistance can reduce current loss and improve the efficiency of energy transmission.

[0033] Regarding the above-mentioned insulating layer 20, the material of the insulating layer 20 can be polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), rubber or polyimide (PI). PVC is a commonly used insulating material with good insulation performance, wear resistance and chemical corrosion resistance. XLPE is a high-performance insulating material with excellent heat resistance, electrical breakdown resistance and mechanical strength. The rubber insulating layer 20 is often used for flexible wires and has good flexibility and wear resistance. PI is a high-temperature insulating material that can remain stable in a high temperature environment and has excellent heat resistance and electrical properties.

[0034] Regarding the flame retardant layer 30, the flame retardant layer 30 covers the insulating layer 20 and can be used to enhance the flame retardant performance of the insulating wire, and can inhibit the spread of flames when the insulating wire encounters a fire. Through such a setting, the spread of flames can be slowed down to a certain extent, the scope of the fire can be limited, and the fire safety of the electrical equipment can be improved.

[0035] The material of the flame retardant layer 30 may be flame retardant polyolefin (FR-PP), flame retardant polyvinyl chloride (FR-PVC) or flame retardant polyethersulfone (FR-POES). Flame retardant polyolefin is a material with good flame retardant properties, which can inhibit the spread of flames in a fire and reduce the generation of smoke and toxic gases. Flame retardant polyvinyl chloride is a specially treated polyvinyl chloride material with high flame retardant and fire resistance. Flame retardant polyethersulfone is a high-performance flame retardant material with excellent heat resistance, fire resistance and electrical properties.

[0036] In this embodiment, the end of the conductor 10 is connected to the insulating terminal 40, and the current first passes through the insulating terminal 40 in the conductor 10 before entering the electrical appliance. Through such a setting, electrical isolation can be achieved at the connection between the conductor 10 and the electrical appliance, preventing current leakage and electrical short circuit, and ensuring the safe operation of the power system.

The insulating sleeve 41 is sleeved on the connecting piece 42, specifically, fixedly connected to the connecting piece 42, so as to enhance the stability of the insulating sleeve 41 and the connecting piece 42 and prevent the connecting piece 42 and the insulating sleeve 41 from falling off.

[0038] In addition, the connector 42 and the conductor 10 are detachably connected. When the connecting terminal is needed, the connector 42 and the conductor 10 can be connected to each other, so that the insulating sleeve 41 is sleeved on the end of the conductor 10; when the connecting terminal is not in use, the connector 42 and the conductor 10 can be detached.

[0039] In some embodiments, a clamping hole 421 is provided on the connector 42, and the conductor 10 is sleeved in the clamping hole 421 to achieve the connection between the connector 42 and the conductor 10. Specifically, a threaded inner wall is provided in the clamping hole 421, and a threaded outer wall is provided on the outer peripheral side of the conductor 10. After the conductor 10 is inserted into the clamping hole 421, the insulating terminal 40 is twisted or the conductor 10 is twisted so that the conductor 10 and the connector 42 are threadedly connected, thereby enhancing the connection stability between the connector 42 and the conductor 10.

[0040] In some embodiments, the connector 42 is made of copper, which has good electrical conductivity and can reduce the loss of current during transmission.

[0041] In some embodiments, the insulating sleeve 41 includes an outer plate 411, which is arranged on the circumference of the insulating sleeve 41 and extends outward. The user can twist the outer plate 411, and the outer plate 411 drives the insulating sleeve 41 to rotate, and the insulating sleeve 41 then drives the connector 42 to rotate. Through such a setting, the threaded connection between the connector 42 and the conductor 10 can be achieved. And by arranging the outer plate 411 on the circumference of the insulating sleeve 41, it is convenient for the user to twist the insulating sleeve 41.
