Embodiment
To describe the preferred embodiments of the present invention in detail now, its example is illustrated in the accompanying drawings.
A method that prevents leakage of current (being called " Leakage Current " hereinafter) is on first ground of terminal enclosure and is included in installation and control switch between second ground of the printed circuit board (PCB) in the portable terminal.Send order then and give control switch when charge in the terminal, switching to first state breaking off first and second ground, and switch to second state to be connected first and second ground when the complete charge of terminal.Yet this control switch has complicated structure, has increased the cost of making the terminal, and after reusing, damages easily.In addition, when when the terminal is recharged, using the terminal, control switch shields the connection between first and second ground, and this has reduced the radio sensitiveness at terminal and has worsened the static and the electromagnetic radiation performance at terminal.
Therefore; Preferably provide and have the terminal that leakage current prevents mechanism; It transmits alternating current and shields direct current in case heads current direction terminal enclosure prevents that thus the user from being shocked by electricity and keeps the radio and the antistatic property at terminal simultaneously when using the terminal and the terminal is being recharged simultaneously.Fig. 1-6 shows this embodiment that prevents mechanism that is included in the portable terminal.
In more detail, Fig. 1 shows the perspective view of portable terminal according to an embodiment of the invention.As shown in the figure, portable terminal comprises first main body 10 and can be connected to second main body 20 of first main body 10 via hinge coupling part 40 with opening.First main body 10 comprises first shell 12 of the overall appearance that forms the terminal; Be installed in first shell 12 front surface be used for input information to the keypad 16 at terminal and be removably mounted on first shell 12 back surface be used to provide the battery 18 of energy to the terminal.The microphone 17 that first main body 10 of portable terminal also comprises a side that is installed in first main body 10 be used to connect the terminals to the charger connector 32 of external power source with the battery 18 that recharges the terminal.
In addition, first shell 12 can be processed to strengthen its outward appearance by metal material.In this case, metal shell 12 itself can and also increase overall contact area as ground thus.Bigger contact area also increases the RF radio and the radiance at terminal.Similarly, can on nonmetallic terminal enclosure, decorate by type metal.In this case, metal finishing can be as the additional ground at terminal.
Further, second main body 20 comprises second shell 22 that is rotatably connected to an end of first main body 10 via hinge coupling part 40, is installed in display module 24 and loud speaker 26 on second shell 22.Be similar to the decoration that first shell, 12, the second shells 22 could be formed or can be comprised metal by metal material.
Then, Fig. 2 shows the sectional view of portable terminal according to an embodiment of the invention.As shown in the figure, main printed circuit board 14 is installed in first shell 12.Main printed circuit board 14 comprises the several different circuits elements that are used for operating mobile terminal, and also on the surface of circuit board 14, has first ground 15.Further, in a side of main printed circuit board 14 charge connector 32 is installed, and this charge connector 32 is electrically connected to the ground 15 of main printed circuit board 14.
In addition, display module 24 has the demonstration printed circuit board (PCB) 26 that is electrically connected to main printed circuit board 14 via FPCB (flexible printed wiring board) 34, receives signal thereby transmit a signal to main printed circuit board 14/ from main printed circuit board 14.Also on the surface that shows printed circuit board (PCB) 26, form second ground 36, and this second ground 36 is connected to first ground 15 of main printed circuit board 14 via FPCB 34.
In addition, thus the main printed circuit board 14 and first shell 12 are connected to each other via coupling components 66 and increase contact area.First leakage current prevents that parts 68 are installed in coupling components 66 and flow to the surface of first shell 12 so that prevent the leakage current that when charger is connected to the terminal via charger connector 32, produces.Fig. 3 is the enlarged drawing that the coupling components 66 and first leakage current prevent parts 68.
In addition, as shown in figs. 1 and 3, second leakage current prevents that parts 60 from comprising that being connected first between the end that shows ground 36 and coupling components 50 prevents parts 62, and is connected second between the other end that shows ground 36 and coupling components 50 and prevents parts 64.Further, leakage current prevents that parts 60 and 68 preferably are implemented as capacitor, and it transmits AC (alternating current) and shielding DC (direct current).Notice that Fig. 5 shows second leakage current with top view and prevents parts 60, the coupling components 50 and second ground 36 are around display 24.
The work of portable terminal according to an embodiment of the invention will be described now.When charger is connected to portable terminal via charger connector 32, change the earth potential at terminal based on the earth potential of charger output, thus because the difference between ground potential and the earth potential produces little leakage current.
Further, because first ground 15 of main printed circuit board 14 is connected to first shell 12 via coupling components 66, leakage current attempts flowing to first shell 12.In addition, because first ground 15 is connected to second shell 22 via the FPCB 34 and second ground 36, the leakage current of generation attempts flowing to the surface of second shell 22.
Yet, when the user is using and the terminal is being recharged simultaneously, prevent that via first and second leakage currents parts 68 and 60 from preventing that leakage current from contacting the user.In addition, be implemented as capacitor because first and second leakage currents prevent parts 68 and 60, these parts transmit alternating current and shielding direct current.Therefore, prevent that the user from being shocked by electricity via direct current (leakage current), the user still can use his or her portable terminal that is charging (that is, because prevent that via first and second leakage currents parts 68 and 60 from transmitting alternating currents) simultaneously.
Then, Fig. 6 shows the sectional view according to the portable terminal of second embodiment of the invention.As shown in the figure; Portable terminal comprises terminal enclosure 80; Comprise several circuit elements and have ground 88 main printed circuit board 82 in its surface; At the display module 84 that terminal enclosure 80 is installed, append to display module 84 front surface touch pads 90 and at the battery 86 of the back mounted on surface of terminal enclosure 80.Further, the terminal also comprises the loud speaker 92 of a side that is installed in terminal enclosure 80 and is installed in the microphone 94 of its opposite side.
Also on the surface of main printed circuit board 82, form ground 88, and when terminal enclosure 80 was formed by metal material, shell 80 was used as the ground that adds.Further, the ground 88 of main printed circuit board 82 is connected to terminal enclosure 80 via coupling components 96.Also leakage current is installed and is prevented parts 98 at coupling components 96.Be similar to first embodiment, leakage current prevents parts 98 shielding DC and transmits AC.That is to say that leakage current prevents that parts 98 preferably are implemented as capacitor, its shielding DC and transmission AC.Therefore, when the user uses the terminal that battery 86 is being recharged, prevent that leakage current from flowing to terminal enclosure 80.And, strengthen static and electromagnetic RF radio and radiance.
Although the present invention can be summarised in some forms under the situation that does not deviate from its spirit and intrinsic propesties; Unless otherwise mentioned; Should be appreciated that the foregoing description is not limited by any details of foregoing description; But should briefly analyze the spirit and scope of the present invention that define in the additional claim, so all variations and improve and all to drop in the boundary line of claim, additional in other words claim has comprised the equivalence in such boundary line.
