Embodiment
In order to make object, technical scheme and the advantage that will invent clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of invention, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
As shown in Figure 2 to Figure 3, the invention provides a kind of antenna structure embodiment based on concentric conductor.
Should comprise based on the antenna structure of concentric conductor: the concentric conductor 3 that antenna body 1 is connected with antenna body 1 with one end, this concentric conductor 3 other end is connected with array signal processing circuit, described antenna body 1 comprises substrate and is arranged on the sheet metal 11 of this substrate, this substrate is provided with fixing welding hole 13, be positioned at sheet metal 11 side after the heart yearn 31 of described concentric conductor 3 runs through fixing welding hole 13, lay respectively at substrate 1 both sides for the solder joint 4 and concentric conductor 3 epidermis solder joint being fixedly connected with sheet metal 11 and concentric conductor heart yearn 31.
Specifically, after the heart yearn of described concentric conductor 31 and antenna body 1 are welded and fixed, the solder joint 4 of formation is positioned at the relative side of concentric conductor 3 body, is namely welded and fixed the both sides that rear sheet metal 11 and concentric conductor 3 body lay respectively at substrate 1.
Described sheet metal 11 is provided with the pad 12 being convenient to weld, this fixing welding hole position 13 is on pad 12, the size and shape of this pad 12 is not limit, square, circular or triangle etc. can be set to as required, be preferably circular, this pad 12 better can facilitate and welded with sheet metal 11 by heart yearn 31.The end of the concentric conductor heart yearn 31 coordinated with fixing welding hole 13 is provided with stay hook, after being convenient to be welded and fixed, can coordinating by stay hook and fixing welding hole 13, and increase the tensile property of antenna structure.The end of this stay hook preferably can exceed the surface of substrate, is convenient to welding more firm, reduces and occurs rosin joint phenomenon.
Because fixing or sheet metal 11 lay respectively at the both sides of substrate 1 with the solder joint 4 of concentric conductor heart yearn 31 and the epidermis solder joint of concentric conductor 3, when can avoid adopting plane-welding between the heart yearn of concentric conductor and epidermis and antenna body on the one hand, because the spacing between heart yearn and epidermis is less, cause the heart yearn of concentric conductor and epidermis two solder joints to form electrical contact, reduce the difficulty of welding; The solder joint of another aspect heart yearn and concentric conductor are positioned at the not homonymy of substrate, increase the tensile strength between concentric conductor and antenna body, namely to concentric conductor apply pulling force time due to heart yearn and fixing welding hole effect, active force is made to disperse to impose on substrate and pad, improving the tensile strength of entire physical, avoiding occurring when assembling damaging phenomenon.
The present invention also provides a kind of antenna manufacturing method based on concentric conductor, and this antenna manufacturing method comprises: on substrate, arrange sheet metal;
First step, substrate arranges sheet metal, specifically on the substrate of insulation, is provided with sheet metal, as stamped circuit on pcb board.
Second step, the substrate being provided with sheet metal arranges fixing welding hole; Specifically, described fixing welding hole is positioned in the middle of the pad of sheet metal, can form electric pathway better when being convenient to welding with sheet metal;
Third step, epidermis twist heart yearn to be welded for concentric conductor being bent and conducts electricity; Specifically, the heart yearn exposed is bent to the shape matched with fixing welding hole, preferably can expose substrate surface when the heart yearn of sweep coordinates with fixing welding hole, the end face of the heart yearn of minimum sweep is not less than substrate surface, ensures that it does not occur the phenomenons such as rosin joint when welding;
4th step, then by bending heart yearn through fixing welding hole, and welding respectively the epidermis of concentric conductor and heart yearn, forms the both sides that two solder joints lay respectively at substrate, is namely welded and fixed the both sides that rear sheet metal and concentric conductor body lay respectively at substrate.
In the present embodiment, described first, second, third and fourth step can in no particular order, and it makes this antenna can not produce substantial influence and special-effect, namely also first can perform second step, then perform first step.
The invention provides a kind of antenna manufacturing method based on concentric conductor, first sheet metal is set on substrate; Again fixing welding hole is set on the substrate being provided with sheet metal; Epidermis twist heart yearn to be welded for concentric conductor being bent and conducts electricity; Finally bending heart yearn is passed fixing welding hole, make the solder joint of the epidermis of twist and heart yearn and substrate lay respectively at the both sides of substrate.
Because the fixing or solder joint of sheet metal and concentric conductor heart yearn and the epidermis solder joint of concentric conductor lay respectively at the both sides of substrate, when can avoid adopting plane-welding between the heart yearn of concentric conductor and epidermis and antenna body on the one hand, because the spacing between heart yearn and epidermis is less, cause the heart yearn of concentric conductor and epidermis two solder joints to form electrical contact, reduce the difficulty of welding; The solder joint of another aspect heart yearn and concentric conductor are positioned at the not homonymy of substrate, increase the tensile strength between concentric conductor and antenna body, namely to concentric conductor apply pulling force time due to heart yearn and fixing welding hole effect, active force is made to disperse to impose on substrate and pad, improving the tensile strength of entire physical, avoiding occurring when assembling damaging phenomenon.
Above execution mode only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to aforementioned embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in aforementioned each execution mode, or equivalent replacement is carried out to wherein portion of techniques feature, and these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each execution mode technical scheme of the present invention.
