embodiment:
Referring to the accompanying drawing that the utility model embodiment is shown, below will describe in more detail the utility model.Yet the utility model can be with realizations such as multi-form, specifications, and should not be construed as the restriction of the embodiment being subject in this proposition.On the contrary, it is abundant and complete open in order to reach proposing these embodiment, and makes more relevant those skilled in the art person understand scope of the present utility model completely.In these accompanying drawings, for clearly visible, may zoom in or out relative size.
As shown in Figures 1 to 4, a kind of die cast metal antenna that the utility model provides, this die cast metal antenna 10 comprise antenna body 11 as shown in the figure and with the antenna holder 12 of the corresponding setting of this antenna body 11, by this antenna body 11, be that an antenna module is this die cast metal antenna with the mutual assembly and connection of this antenna holder 12, this antenna body 11 is main by extrusion process die cast, on antenna body 11, be provided with feeder section, specifically can comprise two antenna feed points 13, and on this antenna holder 12, on the position of these antenna feed point 13 correspondences, be provided with two through holes 14, and this through hole 14 and antenna feed point 13 setting that cooperatively interacts, thereby in forming the process of this die cast metal antenna 10, this antenna feed point 13 runs through this through hole 14 makes this antenna body 11 form and have labyrinth as the antenna module of 3D structure with antenna holder 12 assembly and connections, and while using as antenna in this die cast metal antenna 10 is arranged on mobile terminal, this antenna feed point 13 is connected on the mainboard of this mobile terminal.
Wherein, in specific implementation process, the material of this antenna body 11 is SUS304 stainless steel or SUS316L stainless steel, and the thickness of this antenna body 11 is 0.1-1.0mm, concrete, in actual application, the thickness of this antenna body 11 is 0.2-0.4mm, thereby thickness and the antenna performance of the antenna module forming after itself and antenna holder 12 are assembled all can reach the state of relatively optimizing; And when making this antenna body 11, by extrusion process, in predefined antenna body die casting, carry out die cast, thereby form this antenna body 11; Owing to needing feeder section in this antenna body 11, therefore the antenna feed point 13 of this antenna body 11 can make this antenna feed point 13 and antenna body 11 integrated die-casting moulding by extrusion process rheo-die-casting, also can on antenna body 11, by two shell foots of laser welding, make it form two antenna feed points 13, or this antenna feed point 13 is connected with this antenna body 11, and envelope on this antenna holder 12 as the feeder section of this antenna body 11.Because extrusion process only need to provide a mould, needn't need more other equipment and manufacture craft, reduce in a large number antenna cost.This antenna holder 12 be a plastic cement antenna holder or cabinet (be mobile terminal cabinet directly and antenna holder 12 be connected and fixed), in order to facilitate this antenna body 11 to be fixedly connected with antenna holder 12, position corresponding to this antenna feed point 13 on this antenna holder 12 is provided with through hole 14, thereby when this antenna body 11 is fixedly connected with antenna holder 12, by this antenna feed point 13, run through this through hole 14, thereby make together with antenna holder 12 is assembled into antenna body 11 by the support of this antenna holder 12.
And, in specific implementation process, as shown in Figure 3, together with this antenna body 11 is assembled into antenna holder 12, thereby form the die cast metal antenna 10 of 3D structure 15 as shown in the figure, and in concrete actual application, the die cast metal antenna of this 3D of having structure is applicable to the especially carrier of 3D structure of labyrinth, thereby can effectively utilize in having the mobile terminal of labyrinth.And because this antenna structure is by extrusion process moulding, its structural strength and precision are all better than common metal shell fragment antenna, due to the corrosion resistance of this antenna material itself, after antenna body moulding, can avoid carrying out surperficial antirust corrosion protection and process; Meanwhile, because antenna material itself has solderability, for some complicated antennas, provide advantage, thereby this antenna can be produced in batches, and its cost is extremely low.
In addition, in specific implementation process, as shown in Figure 5, and the concrete manufacture method of this die cast metal antenna, the manufacture craft of its concrete die cast metal antenna comprises the steps:
S1: the structure of determining this antenna holder 12;
S2: according to the 3D structure of antenna holder, determine the needed 3D structure of this antenna, and the structure of the layout of definite antenna body 11 and antenna body 11, and form an antenna body die casting;
