Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public concrete enforcement.
Metalwork for wireless communication terminal of the present utility model, comprises a metal substrate; Described metal substrate is formed with thin-walled, and described thin-walled comprises at least one first tenuity and/or at least one second tenuity; Complete non-conductive process is carried out to described thin-walled; To block conducting of the metallic member of often described first tenuity both sides, or, can conduct to make often described second tenuity circumferential metal part but can not conduct around the second tenuity formation loop.
Wherein, the both sides conducting indication blocking the often metallic member of described first tenuity both sides can comprise the both sides up and down of the first tenuity, the left and right sides, inside and outside both sides etc.
The material of metal substrate can be aluminium, aluminium alloy, almag, stainless steel, kirsite, liquid metal, titanium alloy, carbon steel, steel alloy, iron, the metal material such as copper or copper alloy, but is not restricted to this.
The metallic member worked alone according to needing blocking-up two after non-conductive process and thin formation first tenuity on metal substrate relevant position, a metalwork can be provided with first tenuity of more than 1, thus metalwork can be made to be used for forming multiple antennas.
On metal substrate relevant position, formation second tenuity is thinned according to the metallic member needing after non-conductive process to work alone being arranged in order to form near field antenna after installation coil, that is, often described second tenuity circumferential metal part can conduct but can not form loop around the second tenuity and conduct, when coil is installed, metallic member eddy current can significantly reduce, a metalwork only can there is 1 the second tenuity, then this metalwork can be used for being configured near field antenna separately, second tenuity of more than 2 can certainly be had, in order to non-interference between antenna, between every two second tenuities, one first tenuity can be set.
The method of non-conductive process comprise metal substrate oxidation processes and/or, chemical passivation process and/or, organic or inorganic material surface infiltrates process, processing example is infiltrated as carried out carburizing to metal substrate in the surface of organic or inorganic material, nitriding etc., more specifically, can be anodic oxidation, oxalic acid treatment, differential arc oxidation process, the mode of non-conductive process is not as restriction, and owing to passing through the process of metal substrate non-conductive, thus metalwork is integrated.For differential arc oxidation, aluminum alloy surface can be oxidized depth capacity 400um by differential arc oxidation.We can by milling thin-walled on the hand set machine shell that needs not conduct like this, it is such as the second tenuity, the shape of the second tenuity is determined according to the antenna of required setting, can be such as the shape needed for NFC antenna; walled thickness 700-800um; the thickness of all the other hand set machine shells maintains 1.2mm, non-conductive process be carried out to hand set machine shell, just obtains the thin-walled portion do not conducted.
What deserves to be explained is, what the utility model realized is integrated metalwork, this metalwork may be used for being formed the integrated of various antenna and multiple antennas, during for the formation of antenna, can on the basis of metalwork of the present utility model, carry out interpolation module or metalwork be changed, form antenna with reasonable installation.
Preferably, non-conductive process can be carried out to metal substrate entirety, that is, while thin-walled is formed as non conductive component, each surface of metal substrate is carried out non-conductive process and is formed as non-conductive layer, now, the thickness of metal substrate is greater than the thickness of thin-walled, better, and the thickness of thin-walled is between 0.1 ~ 1.0mm, thus when ensureing the complete non-conductive of thin-walled, metal substrate remainder only forms non-conductive layer on surface.
In one embodiment, can local or be all filled with the insulation division material of strengthening action in thin-walled, and/or, be filled with the insulation division material of strengthening action around thin-walled, to strengthen the fastness of metalwork.Such as can adopt NMT (nanometer injection molding technology) by PPS or PPT injection moulding enter formation first tenuity or formed in the shape offered of the second tenuity, thus strengthening rigidity and the toughness of product, therefore product can be accomplished from the appearance less than the vestige having grooving.
