Description

Technical Field

[0001] This utility model relates to the field of power cord technology, and in particular to a household environmentally friendly power cord with a bio-based flame-retardant composite sheath. Background Technology

[0002] Power cords are wires that transmit electrical energy from a power source to equipment, and are widely used in household appliances, industrial equipment, building power distribution and other fields.

[0003] A search revealed a household environmentally friendly power adapter cable with announcement number CN210640046U. The cable includes a main body, one end of which is electrically connected to a household appliance, and the other end has a power plug. The main body comprises an outer sheath, a waterproof layer, a flame-retardant insulation layer, a fiber layer, a shielding layer, and conductors. The outer sheath is located on the surface of the main body and has an anti-corrosion coating. Inside the outer sheath is a waterproof layer, inside the waterproof layer is a flame-retardant insulation layer, inside the flame-retardant insulation layer is a fiber layer, inside the fiber layer is a shielding layer, and inside the shielding layer are conductors. This invention incorporates a waterproof and flame-retardant insulation layer within the power adapter cable, preventing water ingress and moisture damage, and preventing spontaneous combustion due to temperature increases, thus improving the safety of the power adapter cable. Furthermore, the anti-corrosion coating on the surface of the power adapter cable reduces aging and damage, extending its lifespan and making it safer and more environmentally friendly.

[0004] The power cord in this patent has low protection performance during use. The plug part is prone to poor contact due to frequent bending, which affects the safe use of the power cord. It is also highly dependent on petroleum resources and is not very environmentally friendly. Utility Model Content

[0005] In response to the technical problems in existing patents, such as low protection performance of power cords during use, poor contact due to frequent bending of the plug, affecting the safe use of power cords, high dependence on petroleum resources, and general environmental friendliness, this utility model provides a household environmentally friendly power cord with a bio-based flame-retardant composite sheath.

[0006] The technical solution adopted in this utility model is: a household environmentally friendly power cord with a bio-based flame-retardant composite sheath, comprising: The power cord body includes an environmentally friendly wire and a plug installed at one end of the environmentally friendly wire. An end protection component is installed at the connection point between the environmentally friendly wire and the plug, and the end protection component is used to protect the connection part; The end protection assembly includes a connecting sleeve fitted over the outside of the plug, an extension sleeve mounted on one side of the connecting sleeve, and a shrink sleeve mounted on one side of the extension sleeve.

[0007] Furthermore, a connecting groove is provided on one side of the connecting sleeve, and the connecting groove mates with the plug.

[0008] Furthermore, both the extension sleeve and the shrink sleeve are provided with through holes, which are matched with the environmentally friendly wire.

[0009] Furthermore, the environmentally friendly wire includes a conductor, a shielding layer sleeved on the outside of the conductor, an insulation layer sleeved on the outside of the shielding layer, a filling layer sleeved on the outside of the insulation layer, a buffer layer sleeved on the outside of the filling layer, a flame-retardant reinforcing layer sleeved on the outside of the buffer layer, and a sheath layer sleeved on the outside of the flame-retardant reinforcing layer.

[0010] Furthermore, the filling layer is made of recycled hemp fiber, the buffer layer is made of bio-based elastomer, and the flame-retardant reinforcing layer is made of mica tape.

[0011] Furthermore, the sheath layer material includes a soybean oil derivative polyurethane matrix, phytic acid amine, and bamboo fiber woven mesh.

[0012] The beneficial effects of this utility model are: By connecting the sleeve to the outside of the plug, the extension sleeve is placed on the connection part between the environmentally friendly wire and the plug. The shrink sleeve shrinks the end face, avoiding damage to the environmentally friendly wire and preventing poor contact of the power cord body due to the plug part, thus improving service life and safety.

[0013] The flame-retardant synergy is achieved through a filling layer made of recycled hemp fiber, which reacts with the flame retardant of the sheath during combustion to form a heat insulation layer. The environmental performance of the wire is improved by a buffer layer made of bio-based elastomer material composed of natural rubber. The sheath material is derived from plant-based or microbial synthesis, making it a 100% renewable material, reducing dependence on petroleum resources. After disposal, it can be composted to avoid microplastic pollution. Attached Figure Description
