Technical Field

[0001] This utility model relates to the field of hook and loop fasteners, and in particular to an antistatic hook and loop fastener assembly. Background Technology

[0002] Hook and loop fasteners, also known as Velcro, have been widely used in various fields, such as electronics, clothing, medical devices, apparel and accessories, and automotive interiors, thanks to technological advancements. However, traditional hook and loop fasteners are prone to static electricity buildup due to friction during use, which can attract dust or damage electronic components. For example, patent document CN209628778U, entitled "Antistatic Conductive Hook and Loop Fastener," discloses an antistatic conductive hook and loop fastener that eliminates static electricity by adding conductive wires.

[0003] However, the conductive layer formed by the conductive wire in the above-mentioned technical solution suffers from problems such as easy detachment, poor anti-static effect, and short lifespan during use. Therefore, it is necessary to develop a newer technical design with structural components that have a long anti-static lifespan to solve these problems. Utility Model Content

[0032] To further understand the utility model content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0033] like Figure 1-3As shown, the antistatic hook and loop fastener assembly includes a first hook and loop fastener 1 and a second hook and loop fastener 2. Both the first hook and loop fastener 1 and the second hook and loop fastener 2 are provided with a carrier layer 3 and an adhesive layer 4, which are fixedly connected. The adhesive layer 4 includes a hook surface layer 41 and a textured surface layer 42. The hook surface layer 41 is disposed on the first hook and loop fastener 1 or the second hook and loop fastener 2, and the textured surface layer 42 is disposed on the first hook and loop fastener 1 or the second hook and loop fastener 2. A conductive fiber layer 5 is disposed on the hook surface layer 41, embedded within it. A conductive yarn layer 6 is disposed on the textured surface layer 42, and the conductive yarn layer 6 and the textured surface layer 42 are alternately woven. In this embodiment, by embedding conductive fibers into the hook surface layer, and alternately weaving conductive yarn and textured surface layer, the conductive structure becomes more stable. The physical conductive structure replaces the surface coating, avoiding failure caused by coating wear and significantly extending the service life. Of course, this is not limited to this; other methods can be used to prevent the conductive fiber layer and conductive yarn layer from falling off and extend the service life.

[0034] Specifically, the conductive fiber layer 5 is made of nylon with a silver, copper, or nickel plating, or polyester with a silver, copper, or nickel plating. In this embodiment, the conductive fiber layer is made of nylon with a silver plating, or nylon with a copper plating, or nylon with a nickel plating, or polyester with a silver plating, or polyester with a silver-copper plating, or polyester with a nickel plating. By selecting the material of the conductive fiber layer, the flexibility and bend resistance of the conductive fiber layer are ensured while enabling rapid discharge of the charge generated by friction. Of course, the material of the conductive fiber layer is not limited to this; it can be any other material that ensures the flexibility and bend resistance of the conductive fiber layer while enabling rapid discharge of the charge generated by friction.

[0035] Specifically, the conductive yarn layer 6 is composed of carbon fiber and one or a combination of cotton or polyester. In this embodiment, the conductive yarn layer is a blend of carbon fiber and cotton or polyester. This design reduces production costs while ensuring the yarn strength and conductivity of the conductive yarn layer. Of course, the material of the conductive yarn layer is not limited to this; it can be any material that reduces production costs while ensuring the yarn strength and conductivity of the conductive yarn layer.

[0036] Specifically, such as Figure 2-3 As shown, a reinforcing layer 7 is provided within the load-bearing layer 3 to improve overall rigidity. The reinforcing layer 7 is made of a blend of polyester fiber and carbon fiber. In this embodiment, the reinforcing layer effectively improves the tensile strength of the hook and loop fastener, and the carbon fiber helps to form local conductive paths, preventing the reinforcing layer from blocking static electricity discharge. Of course, it is not limited to this; other materials that improve tensile strength and prevent the reinforcing layer from blocking static electricity discharge can also be used.

[0037] Specifically, such as Figure 2-3As shown, an insulating layer 8 is coated on the surface of the reinforcing layer 7. The insulating layer 8 is made of polyurethane, polyimide, or fluorinated ethylene propylene copolymer. In this embodiment, the insulating layer is made of polyurethane, polyimide, or fluorinated ethylene propylene copolymer. The insulating layer prevents the reinforcing layer from contacting external conductive components, effectively avoiding the risk of accidental short circuits. Of course, it is not limited to this; other materials that avoid the risk of accidental short circuits can be used.

[0038] Specifically, the material of the support layer 3 is polyamide. In this embodiment, the high resilience of the polyamide material ensures that the hook and loop fastener does not undergo permanent deformation after repeated bending, effectively improving the service life of the hook and loop fastener. Of course, it is not limited to this; the support layer can be made of other materials that improve service life.

[0039] Working principle: In use, the first and second hook and loop fasteners work in conjunction with external electronic components. The hook and loop components engage to ensure a secure connection between the first and second hook and loop fasteners. Both the conductive fiber layer and the conductive yarn layer form conductive pathways, effectively dissipating charge and preventing charge accumulation. The reinforcing layer effectively improves the tensile strength of the hook and loop fasteners, and the carbon fiber helps form local conductive pathways, preventing the reinforcing layer from blocking static electricity discharge. The insulating layer prevents the reinforcing layer from contacting external conductive components, effectively avoiding the risk of accidental short circuits. The high resilience of the polyamide material ensures that the hook and loop fasteners do not undergo permanent deformation after repeated bending, effectively improving their service life.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
