Abstract
The invention discloses a covering film used for an outer cover of a notebook personal computer, which comprises a covering film body provided with a transparent plastic film layer, an adhesive layer, a printing pattern layer and a vacuum coating layer, as well as another adhesive layer and a sputtering metal coating, wherein, the another adhesive layer and the sputtering metal coating are orderly laid on the inner surface of the covering film body. The covering film used for the outer cover of the notebook personal computer plates the sputtering metal coating on the tabulate covering film body, and the sputtering metal coating has even thickness, so the outer cover of the notebook personal computer can not produce potential difference. In the invention, a grounding lug which can be electrically connected with a grounding point of the notebook personal computer is reserved at the outer edge of the covering film, or the covering film is provided with a grounding hole for a grounding wire of the notebook personal computer to pass through to electrically connect, which can be convenient for the covering film to ground.
Description
Technical field
The present invention relates to a kind of coverlay, especially a kind of coverlay that is used for notebook-type computer outer cover.
Background technology
Existing notebook-type computer outer cover comprises enclosing cover body and coverlay, and the outside surface of enclosing cover body is fixed in the coverlay injection moulding.Coverlay comprises transparent plastic film layer, bond layer, printing pattern layer and vacuum coating from outside to inside successively.During production, earlier the transparent plastic film layer is carried out surface treatment, inside surface at the transparent plastic film layer that is coated with bonding agent prints out required color according to the pattern that designs with environment-friendly ink then, the printing pattern layer of style, and then outside printing pattern layer, be coated with a vacuum coating, form processing at last, obtain the coverlay that is complementary with notebook-type computer outer cover shape size, to inlay in the mould of plastics of correspondence through the coverlay of handling that is shaped again, injection moulding enclosing cover body, coverlay is injection-moulded in the enclosing cover body, finally forms notebook-type computer outer cover.
Coverlay is other version also, can exchange as the position of vacuum coating and printing pattern layer, or vacuum coating and printing pattern layer alternately repeats.
Existing this notebook-type computer outer cover, in order to realize electro-magnetic screen function, traditional practice is to be inlaid with sheet metal in a side of the close liquid crystal display of enclosing cover body, and sheet metal is thicker, not only than waste material but also can increase the weight of notebook computer, generally do not adopt.The comparatively popular practice is at the side sputter last layer metal film of enclosing cover body near liquid crystal display now, because the enclosing cover body is uneven near a side of liquid crystal display, and there are some dead angles, the easy became uneven of metal film on the sputter is even, can make notebook-type computer outer cover produce potential difference (PD) like this, thereby the reduction shield effectiveness, anti-electromagnetic-radiation, antijamming capability also descend.
Summary of the invention
The purpose of this invention is to provide that a kind of shield effectiveness is good, anti-electromagnetic-radiation and the strong coverlay that is used for notebook-type computer outer cover of antijamming capability.
Technical scheme of the present invention is such: the coverlay that is used for notebook-type computer outer cover, comprise the coverlay body that is provided with transparent plastic film layer, bond layer, printing pattern layer and vacuum coating, also comprise another bond layer and jet-plating metallization rete, above-mentioned another bond layer and above-mentioned jet-plating metallization rete are laid in the inside surface of above-mentioned coverlay body successively.
Above-mentioned transparent plastic film layer is PC plastic layer or PET plastic layer.
The outer of above-mentioned coverlay is reserved with the ground connection lug that can be electrically connected with the earth point of notebook computer.
Above-mentioned coverlay offers and can penetrate the ground hole that is electrically connected for the ground wire of notebook computer.
After adopting such scheme, the coverlay that is used for notebook-type computer outer cover of the present invention is plated in the jet-plating metallization rete on the flat coverlay body, and jet-plating metallization rete thickness is even, and notebook-type computer outer cover can not produce potential difference (PD).And among the present invention, the outer of coverlay is reserved with the ground connection lug or the coverlay that can be electrically connected with the earth point of notebook computer and offers and can penetrate the ground hole that is electrically connected for the ground wire of notebook computer, can make things convenient for coverlay to carry out ground connection.

Fig. 2 is the local cut-away enlarged view of Fig. 1.
Fig. 3 is the structural representation of coverlay of the present invention.
Embodiment
The present invention is used for the coverlay of notebook-type computer outer cover, and as shown in Figure 1, 2, the outside surface of enclosing cover body 1 is fixed in coverlay 2 injection mouldings.
As shown in Figure 3, coverlay 2 comprises coverlay body 21 and bond layer 22, jet-plating metallization rete 23, coverlay body 21 comprises transparent plastic film layer 211, bond layer 212, printing pattern layer 213 and vacuum coating 214 from outside to inside successively, bond layer 22 and jet-plating metallization rete 23 cover the inside surface of coverlay body 21 successively, and the outer of coverlay 2 is reserved with the ground connection lug (not shown) that can be electrically connected with the earth point of notebook computer.Also can on coverlay 2, offer among the present invention and can penetrate the ground hole that is electrically connected for the ground wire of notebook computer.
Coverlay body 21 is other version also, and as the position of vacuum coating 214 and printing pattern layer 213 can be exchanged, or vacuum coating 214 and printing pattern layer 213 alternately repeat.
During production, earlier transparent plastic film layer 211 is carried out surface treatment, inside surface at the transparent plastic film layer that is coated with bond layer 212 prints out required color according to the pattern that designs with environment-friendly ink then, the printing pattern layer 213 of style, and then outside printing pattern layer 213, be coated with a vacuum coating 214, outside vacuum coating 214, coat bond layer 22 again, then outside bond layer 22, plate jet-plating metallization rete 23, cutting edge at last is shaped handles, reserve the ground connection lug, just obtain the coverlay 2 that is complementary with notebook-type computer outer cover shape size, to inlay in the mould of plastics of correspondence through the coverlay of handling 2 that is shaped again, injection moulding enclosing cover body 1, coverlay 2 is injection-moulded in enclosing cover body 1, finally forms notebook-type computer outer cover.
Among the present invention, transparent plastic film layer 211 can be made by PC plastics (polycarbonate) or PET plastics (poly terephthalic acid class plastics).
The coverlay that is used for notebook-type computer outer cover of the present invention is plated in jet-plating metallization rete 23 on the flat coverlay body 21, and jet-plating metallization rete 23 thickness are even, and notebook-type computer outer cover can not produce potential difference (PD).And among the present invention, the outer of coverlay 2 is reserved with the ground connection lug or the coverlay that can be electrically connected with the earth point of notebook computer and offers and can penetrate the ground hole that is electrically connected for the ground wire of notebook computer, can make things convenient for coverlay 2 to carry out ground connection.
