In conjunction with above-mentioned feature, the concrete grammar of manufacturing mobile telephone external antenna provided by the present invention is as follows:
Step 1: design and make one with the supporting aerial plug of GB test interface, be provided for the metal probe of transmission signals in plug inside, and to make the shell of this aerial plug be metal-coating.As (a) of Fig. 2 with (b), when test interface did not have plug to insert at ordinary times, circuit board signal A1 linked to each other with built-in antenna of mobile phone end A2 by interface; When plug inserts, the probe of plug disconnects the connection shell fragment of test interface inside, and promptly circuit board signal A1 end disconnects with the former built-in aerial A2 end of mobile phone, is transformed into circuit board signal and links to each other with external antenna, what this moment, mobile phone just used is external antenna, recovers former connection after extracting external antenna; The metal shell of plug links to each other with the metal shell of test interface, because the metal shell of test interface is to link to each other with mobile phone ground, so the test interface shell has the effect that shielding is disturbed; Make in addition one with the suitable plastics gum cover of plug, put on gum cover to plug during at ordinary times without external antenna, can protect aerial plug.According to testing circuit board of mobile phone interface standard dimensions, at the urceolus diameter 3.2mm of this this example of specification plug 1, length 3.5mm adopts stainless steel, inner stainless steel probe diameter 0.5mm, protective cap urceolus diameter 3.4mm, long 4.0mm.
Step 2: according to the required antenna performance that reaches, design and determine the metal pull bar of accurate size specification, can find the signal optimum state by flexible metal pull bar when the user uses.This metal pull bar adopts stainless steel, links to each other with the more piece metal tube is stacked, and length is 150mm when stretching fully, and length is 50mm when shrinking fully, caliber thickness 2.5mm, the thinnest 0.7mm of place.
Step 3: make one by the stacked linking of becket, and the metal software that can twist; And the metal software links to each other the metal probe of aerial plug with the metal pull bar conduction, promptly metal software and plug, metal pull bar weld together, and guarantee that signal can transmit between metal pull bar, software, plug and mobile phone circuit.Software can allow the user transfer to the metal pull bar direction arbitrarily angled; find the best reception state of signal; the design of metal software simultaneously; can make the user in the process of adjusting yoke antenna; active force can not act directly on the aerial plug; can make like this that aerial plug is difficult for dropping in the adjustment process, protect the probe of aerial plug inside not fragile again simultaneously.This metal software is linked to each other by the fine layer by layer steel loop of the appearance of spring-like, can twist typing, length 18mm, metal caliber 2.6mm.
Step 4: make a plastic cap for metal pull bar, the external diameter of plastic cap is more bigger than the external diameter of pull bar contact portion, and plastic cap can make things convenient for the user that metal pull bar is stretched out from complete compressive state, strengthens feel and experiences.In addition, smooth plastic cap is repacked at the plastic cap top into, i.e. the appearance of hand-written nib, and this external antenna just can be used as the touch screen writing pen and use so.The similar taper of the shape of this metal pull bar plastic cap, taper bottom surface circle interlocks mutually with the thinnest place of pull bar afterbody, and the circle footpath is more bigger than the thinnest place of pull bar size, 1.0mm, the position of outstanding plastics makes the user be convenient to telescopic lever, and plastic cap adopts hot melting way mutually bonding with metal pull bar.
In the above step, with metal pull bar, the metal software, the plug inside probe is weldingly connected, and this has just constituted the core component of whole external antenna.After plug inserted the mobile phone test interface, the plug metal outer cylinder will link to each other with test interface outer cover metal ground, played the shielding interference effect, and is for fear of plug urceolus and internal probe short circuit, middle with plastisol isolation, the structure of similar coaxial cable.This example entire product is profile total length 85mm when pull bar is flexible fully, and the tapered cap top tip part is smooth plastic cap, can be used as writing pen, and is very easy to use.
The present invention can also not adopt the radio frequency test interface of circuit board of mobile phone, uses 3.5mm earphone jack commonly used instead, and perhaps the usb data interface adopts this scheme also to have certain versatility and practicality as the insertion interface of external antenna, is user-friendly to.
Referring to shown in Figure 9,
Among the figure, ANT700,701,702nd, the tie point of built-in antenna of mobile phone, L790, L764, C706 is the π type impedance matching network of mobile phone test interface J700 to antenna, and J700 is the mobile phone test interface, and OUT links to each other with mobile phone internal radio frequency circuit, this partial circuit is the necessary basic circuit of mobile phone, need not to increase extra circuit design again.When not having external antenna to insert, the A1 end of test interface links to each other with the mobile phone radio frequency circuit with A2 end built-in aerial, uses built-in aerial; When external antenna inserted, the A1 of test interface end disconnected with the A2 end, is converted to external antenna and links to each other with the mobile phone radio frequency circuit, and what this moment, mobile phone used is external antenna.
External antenna for mobile phone provided by the present invention and the contrast of conventional built-in antenna experiment test are as follows:
