Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to an anti-crush cable for household appliances. Background Technology

[0002] Currently, cables used in household appliances generally have a simple structure, usually consisting of an outer insulation layer and two internal conductors. During use, because household appliances need to be moved frequently and the socket location is not fixed, electrical cables inevitably need to be bent, folded, or even stepped on and squeezed. However, existing electrical cables do not have good resistance to compression, which can easily lead to damage to the internal conductors of the cable. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an anti-crushing cable for household appliances, addressing the above-mentioned shortcomings.

[0004] To solve the above technical problems, the present invention adopts the following technical solution:

[0005] An anti-crush cable for household appliances includes, from the inside out, a conductor, an insulation layer, a flame-retardant layer, a foam layer, an armor layer, and an outer sheath.

[0006] The foaming layer includes a first foaming layer and a second foaming layer. The first foaming layer is wrapped around the outside of the insulating layer, and the second foaming layer is wrapped around the outside of the first foaming layer. The armor layer is made of multiple aluminum strips wrapped around each other, with the outer edge of each aluminum strip resting on the inner edge of the adjacent aluminum strip.

[0007] Furthermore, the first foam layer is a polyethylene foam layer.

[0008] Furthermore, the second foaming layer is a polyurethane foam layer.

[0009] Furthermore, the outer protective layer is made of polyvinyl chloride.

[0010] Furthermore, the flame-retardant layer is made of aluminum hydroxide flame retardant.

[0011] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0012] This invention significantly enhances the overall structure of the cable by adding a shielding layer, a foaming layer (including a first foaming layer and a second foaming layer), and an armor layer. This effectively resists physical damage such as bending, folding, stepping, and squeezing, protecting the internal conductors from damage. The first foaming layer is made of polyethylene, which has good insulation properties and is lightweight. The second foaming layer is made of polyurethane foam, which has excellent elasticity and shock resistance. The armor layer is made of aluminum tape, providing good shielding and mechanical protection. The outer sheath is made of polyvinyl chloride, which has wear-resistant, corrosion-resistant, and flame-retardant properties.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the cross-sectional structure of this utility model.

[0015] The attached diagram lists the components represented by each number as follows:

[0016] 1. Wire; 2. Insulation layer; 3. First foam layer; 4. Second foam layer; 5. Armor layer; 6. Outer sheath; 7. Flame retardant layer. Detailed Implementation

[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0018] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figure 1 As shown, an anti-crush cable for household appliances includes, from the inside out, a conductor 1, an insulation layer 2, a flame-retardant layer 7, a foam layer, an armor layer 5, and an outer sheath 6.

[0020] The foaming layer includes a first foaming layer 3 and a second foaming layer 4. The outer side of the insulating layer 2 is covered with the first foaming layer 3, and the outer side of the first foaming layer 3 is covered with the second foaming layer 4. The armor layer 5 is made of multiple aluminum strips wrapped around each other, with the outer edge of each aluminum strip resting on the inner edge of the adjacent aluminum strip.

[0021] In one embodiment, the first foam layer 3 is a polyethylene foam layer.

[0022] In one embodiment, the second foaming layer 4 is a polyurethane foam layer.

[0023] In one embodiment, the outer protective layer 6 is made of polyvinyl chloride.

[0024] In one embodiment, the flame retardant layer 7 is made of aluminum hydroxide flame retardant.

[0025] The working process of this utility model is as follows: The foam layer (including the first foam layer 3 and the second foam layer 4) acts as a buffer layer, which can absorb and disperse external pressure and reduce the deformation of the cable when it is squeezed. The armor layer 5 is made of multiple aluminum strips wrapped around it, providing additional mechanical protection and shielding effect to prevent the cable from being punctured or cut by sharp objects.

[0026] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
