Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of conductive cloth, in particular to a conductive cloth for wrapping an antenna. BACKGROUND
[0002] Conductive cloth is a kind of fabric that has been treated to make it conductive. It is made by coating a base fabric, usually made of nylon or polyester, with a layer of metal, such as copper or nickel. This makes the fabric conductive and allows it to carry an electric current. Conductive cloth can be used in a variety of applications, including electronics, telecommunications, and medical devices.
[0003] Conductive cloth is often used to wrap components to improve their electrical properties. When used on an antenna, it can improve the antenna's conductivity, reduce electromagnetic interference (EMI), enhance signal stability, protect the antenna from physical damage, and adapt to different usage environments.
[0004] Current processing methods involve making horizontal indentation lines on the product, such as shown in the figure. The indentation lines release the stress on the conductive cloth, making it softer and more secure when wrapped. Figure 1 Figure 2 The middle blue position is the handle release film, the red arrow position has a force extending upward, when reaching the indentation line position, because the indentation line position is relatively soft and has an indentation line protrusion, the elastic tension of the bent conductive cloth restores to the original state, when the tension of the conductive cloth inside is greater than the adhesive force between the two layers of conductive cloth adhered to each other, the risk of the conductive cloth opening (blasting) is greater. SUMMARY
[0005] Based on the defects in the prior art, the purpose of the present application is to provide a conductive cloth for wrapping an antenna which prevents blasting.
[0006] The purpose of the present application is achieved by the following technical solutions:
[0007] The technical solutions of the present application provide a conductive cloth for wrapping an antenna which prevents blasting, comprising the following structure:
[0008] The conductive cloth body is a convex structure, which is divided into a first rectangle on the upper side and a second rectangle on the lower side, and is integrally formed; the bottom edge of the convex shape is the length direction of the conductive cloth body; the first surface of the conductive cloth body is provided with an indentation line perpendicular to the length direction of the conductive cloth, and the first surface is exposed on the outside; the second surface of the conductive cloth body is provided with double-sided adhesive tape;
[0009] The handle release film is provided on the side of the double-sided adhesive tape of the conductive cloth body close to the bottom edge of the convex shape, and is an L-shaped structure and exposes a handle; the part of the conductive cloth body to which the handle release film is attached does not cover the indentation line;
[0010] The auxiliary protective film is attached to the double-sided adhesive tape of the conductive cloth body which is not covered by the handle release film, and a plurality of conductive cloths are provided on one auxiliary protective film.
[0011] Further, when in use, the part of the handle release film attached to the conductive cloth body is pinched, the conductive cloth body is removed from the auxiliary protective film together with the handle release film, the double-sided adhesive tape is exposed, and one side of the double-sided adhesive tape is wrapped and pasted on the antenna; at this time, the handle release film is in a raised state, and further in use, the handle release film is torn off, the remaining part of the double-sided adhesive tape on the conductive cloth body is wrapped and pasted on the antenna, realizing complete wrapping of the conductive cloth on the antenna, effectively preventing the conductive cloth from blasting on the antenna, and prolonging the service life.
[0012] Further, the size of the first rectangle is 10-15 mm in length and 3-5 mm in width; the size of the second rectangle is 12-17 mm in length and 4-6 mm in width.
[0013] Further, the length of the indentation line is greater than 1.5 times the circumference of the antenna to be wrapped, so that after wrapping, half of the last circle can be pressed on the indentation line of the previous circle, making the wrapping more secure. The diameter of the general antenna is about 1mm, and the length of the indentation line and the size of the conductive cloth are determined according to the actual diameter.
[0014] Further, the width of the indentation line is 0.1-0.3mm, and the depth is 1 / 3-2 / 3 of the thickness of the conductive cloth body.
[0015] Further, the distance between every two indentation lines is 1-1.5mm; the distance between the two ends of each indentation line and the upper and lower edges of the convex shape is 1-4mm.
[0016] Further, the material of the conductive cloth is polyester fiber cloth.
[0017] Further, the material of the handle release film is PET.
[0018] Further, the material of the auxiliary protective film is OPP.
[0019] Further, the conductive cloth for wrapping the antenna to prevent explosion is prepared by using a stamping method on a hardware mold, and the specific processing scheme is as follows:
[0020] S1. Place the lower plate of the hardware mold on the workbench, and place the auxiliary protective film, the handle release film and the conductive cloth body on the lower plate in turn;
[0021] S2. Install the knife die on the upper plate of the hardware mold, align the upper plate and the lower plate after installation, and place it in the die cutting machine for die cutting and indentation, to finally obtain a conductive cloth for wrapping the antenna to prevent explosion.
[0022] Compared with the prior art, the present application has at least the following advantages:
[0023] (1) The indentation line of the product is changed to the vertical direction, and the stretching force will extend upward, and when reaching the indentation line position, the horizontal force will be reduced in the indentation line due to the softness and convexity of the indentation line position, reducing the risk of explosion of the indentation line. The tail of the last wrapping indentation line (close to the handle position) can be buckled on the indentation line of the previous circle (i.e. the indentation line of the previous circle is wrapped by the outermost indentation line), making the wrapping more secure and not easy to explode.
[0024] (2) In the operation process of the present application, only the way of cutting (stamping) indentation line is changed from horizontal to vertical, and the process is not changed in the process, and the processing cost is unchanged.
[0025] (3) The proportion of the product made by the transverse indentation line method and wrapped with wire that burst open is about 15%, and the proportion of the product made by the vertical indentation line method and wrapped with wire that burst open is reduced to less than 1% after adjustment, indicating that the anti-burst effect of the vertical indentation line is much better than that of the existing transverse indentation line.
