Abstract
A conductive foam used for mobile phone casings comprises conductive foam, a double-sided adhesive tape, a transparent adhesive tape and release paper. The double-sided adhesive tape is coated on the transparent adhesive tape; the double-sided adhesive tape at the upper surface of the transparent adhesive tape is provided with the conductive foam; the double-sided adhesive tape at the lower surface of the transparent adhesive tape is provided with the release paper; the conductive foam is folded through a bending machine so as to form a square-shape structure; and a special mirror finish cutting machine performs die-cutting on the conductive foam, such that the conductive foam can be molded with one step, wherein the height of the mirror finish cutting machine is 3 mm, the angle of the mirror finish cutting machine is 25 degrees, and the mirror finish cutting machine is straight inside and oblique outside. The conductive foam is molded with one step through the flat-bed die cutting machine; broken filaments will not be formed in die cutting; and therefore, the conductivity of mobile phones can be greatly improved, and the service lives of the mobile phones can be prolonged. Moreover, the conductive foam used for the mobile phone casings is advantageous in low cost, easiness in implement, excellent effect in implement and broad market prospect.
Description
Technical field
The utility model relates to a kind of conducting foam, especially relates to a kind of conducting foam for handset shell.
Background technology
At present, along with mobile phone is more and more universal, the competition between the mobile phone producer also also grows in intensity, and this competition not only is embodied in outward appearance, and prior meeting embodies the stable aspect of lying in machine, such as the Electrostatic protection aspect.Usually, machine is after using a period of time, and the user can find that the Electrostatic protection ability can descend to some extent, and having the deadlock phenomenon can occur, even the number of times that As time goes on crashes also comes more frequently, has brought great inconvenience for user's use.The conduction bubble is continuous as continuous for the special type bubble that strengthens conductivity in the handset shell.Have White-opalescent, conductivity and be normal more than three times etc. characteristics, be applicable to strengthen conductivity in the handset shell; Now be widely used in mobile phone plastics drain pan; When but existing conduction bubble silk floss carried out cross cutting, lousiness appearred in product frame easily.
Summary of the invention
The utility model purpose provides a kind of conducting foam for handset shell.Technical problems such as lousiness appear all around easily to solve the existing in prior technology conducting foam.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of conducting foam for handset shell comprises conducting foam, double faced adhesive tape, adhesive tape, strippable paper; Be coated with double faced adhesive tape on the described adhesive tape, the layers of two-sided of this adhesive tape upper surface is provided with conducting foam.
As preferably, the layers of two-sided of described adhesive tape lower surface is provided with release liners.
As preferably, described conducting foam is converted into square shape by bender, and by the die-cut one-shot forming above the conduction bubble is continuous of special moulding machine.
As preferably, described machine mould cutter adopts knife up 3mm, 25 ° of angles, interior straight outer oblique minute surface cutter.
The utility model lousiness can not occur by the one-shot forming of flat cutting die cutter during cross cutting, and it has significantly promoted the mobile phone electric conductivity, prolongs mobile phone useful life.Resistance to vibration and anti-impact force all obviously improve.And, with low cost, easy to implement, and implementation result is good.Market prospects are wide.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Fig. 1 is structural representation of the present utility model.As shown in Figure 1, a kind of conducting foam for handset shell mainly is made up of conducting foam 4, double faced adhesive tape 3, adhesive tape 2, strippable paper 1 etc.; Wherein be coated with double faced adhesive tape 3 on the adhesive tape 2, the layers of two-sided 3 of these adhesive tape 2 upper surfaces is provided with conducting foam 4; The layers of two-sided of adhesive tape 2 lower surfaces is provided with release liners 1.
Conducting foam 4 is converted into square shape by bender, and by the die-cut one-shot forming above conduction bubble continuous 4 of special moulding machine, machine mould cutter adopts knife up 3mm, 25 ° of angles, interior straight outside oblique minute surface cutter.
Claims (2)
