Description

Technical Field

[0001] This utility model relates to the field of shielding film technology, specifically a shielding film for protecting cables. Background Technology

[0002] Cable shielding film is a layer of semi-conductive material wrapped around the surface of the cable conductor or insulation layer. It is mainly used to protect the cable and prevent electromagnetic interference.

[0003] However, existing shielding film designs for cables have shortcomings. For example, the surface is at risk of being scratched, and since they are directly adhered to the surface of the cable conductor or insulation layer without protecting the adhesive layer, dust can easily stick to it. In addition, once the shielding film is wrapped around the cable conductor and insulation layer, it cannot be quickly cut and requires tools such as scissors, which is quite cumbersome.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] To address the problems existing in the prior art, this embodiment provides the following technical solution: a shielding film for protecting cables, comprising a shielding film body 1 composed of multiple layers of materials, which effectively enhances the shielding performance of the shielding film body 1; the shielding film body 1 can be rolled up outside a winding drum 4 and is located inside the limiting plates 5 on the left and right sides of the winding drum 4; an elastic rope 7 is installed outside the fixing buckle 6 located inside the lower part of the limiting plate 5; the elastic rope 7 has elasticity; when the shielding film body 1 is used up, it can be rolled up, and then the elastic rope 7 is put on the outside of the rolled-up shielding film body 1, which can ensure the neatness of the shielding film body 1 after use; in addition, tear strips 8 are provided between the shielding film bodies 1 to facilitate the division of the shielding film bodies 1.

[0025] like Figure 1 and Figure 2 As shown, the shielding film body 1 is composed of multiple layers of materials. A conductive layer 11 is provided in the middle of the shielding film body 1. The conductive layer 11 is an aluminum foil with a thickness of about 0.01-0.15 mm. Next, an insulating layer body 12 is provided on the outside of the conductive layer 11. The insulating layer body 12 is about 0.05-0.2 mm thick. The insulating layer body 12 can prevent the conductive layer 11 from directly contacting the external environment and avoid damage to the conductive layer 11 due to physical damage such as friction and compression, thereby maintaining the shielding effect. It can also block the direct transmission path of electromagnetic signals and reduce the interference of external electromagnetic waves on internal signals. At the same time, a first adhesive layer 13 is provided on the outside of the insulating layer body 12. The first adhesive layer 13 facilitates the adhesion of the protective layer 14 to the insulating layer body 12. The protective layer 14 covers the surface of the insulating layer body 12. The protective layer 14 is about 0.03-0.08 mm thick and is a plastic film. It can enhance the mechanical strength and environmental resistance of the conductive layer 11 and prevent the conductive layer 11 from being scratched.

[0026] Additionally, a waterproof layer 16 is provided on the outer surface of the protective layer 14. The waterproof layer 16 is approximately 0.005-0.01 mm thick and has waterproof properties, effectively preventing moisture and oil from entering the conductive layer 11. At the same time, a second adhesive layer 15 is provided on the inner surface of the protective layer 14. The second adhesive layer 15 facilitates the subsequent wrapping of the shielding film body 1 around the outer surface of the cable conductor or insulation layer. Meanwhile, a dustproof layer 17 is adhered to the outer side of the second adhesive layer 15, which can prevent dust from entering the second adhesive layer 15.

[0027] By providing a tear-off tab 2 on one side of the dustproof layer 17, when it is necessary to wrap the shielding film body 1 around the outside of the cable conductor or insulation layer, the tear-off tab 2 can be grasped and pulled. At this time, the fingers of the other hand can grasp the limiting tab 3 provided on the outside of the waterproof layer 16. The limiting tab 3 is located below the tear-off tab 2. That is, one hand holds the limiting tab 3, and the other hand can pull the tear-off tab 2 to tear off the dustproof layer 17 from the surface of the second adhesive layer 15. Then, the second adhesive layer 15 is adhered to the surface of the cable conductor or insulation layer, and the shielding film body 1 is wrapped around the surface of the cable conductor or insulation layer layer by layer.

[0028] A tear strip 8 is provided on the inner side of the shielding film body 1. The tear strip 8 makes it easy to tear and separate the shielding film body 1 after it is wrapped around the surface of the cable conductor or insulation layer. The shielding film body 1 can be separated without the need for tools such as scissors, which greatly improves the wrapping efficiency of the shielding film body 1.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the shielding film body 1 is initially wound up and sleeved on the outside of the winding drum 4. Simultaneously, symmetrical limiting plates 5 are arranged on the outside of the winding drum 4. The limiting plates 5 are attached to the side of the shielding film body 1 after winding, preventing dust from entering the interior of the shielding film body 1 from the side and causing contamination. After use, the shielding film body 1 can be rewound and recycled to the outside of the winding drum 4. A fixing buckle 6 is symmetrically installed on one side of the inside of the limiting plate 5, and an elastic rope 7 is provided on the outside of the fixing buckle 6. The elastic rope 7 is elastic; when the shielding film body 1 is wound up, the elastic rope 7 can be sleeved on the outside of the winding drum 4, located on both sides of the outer side of the wound shielding film body 1, thus limiting the shielding film body 1 and ensuring it is firmly wound on the outside of the winding drum 4. This ensures that the shielding film body 1 can be neatly wound up and placed after use.

[0030] The working principle of the shielding film used to protect cables is as follows: the shielding film body 1 is composed of multiple layers, which can effectively enhance the shielding, waterproof and scratch-resistant properties of the shielding film body 1, and improve the overall performance of the shielding film body 1. At the same time, tear strips 8 are set inside the shielding film body 1 to facilitate the cutting of the shielding film body 1 after it is wrapped. In addition, after the shielding film body 1 is used up, it can be rolled up and limited so that it can be placed neatly.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
