Description
Technical field
The present invention relates to a kind of portable terminal.
Background technology
Mobile phone takes place through regular meeting and falls into the situation in the water accidentally in the user when using mobile phone; At present the mobile phone of water inlet evaporates fully at moisture and can not start shooting as last; Some mobile phone even meeting cause the damage of motherboard circuit owing to water inlet; Thereby cause losing of inner original information of mobile phone and data, this data is lost and can't be recovered often.
For this reason, the existing method that prevents the mobile phone water inlet makes water be not easy to get into mobile phone inside for increasing body seal property.Yet, can not make the mobile phone waterproof fully even increased the sealing of shell first, second such shell can increase the heat radiation that cost also is unfavorable for mobile phone simultaneously.
Summary of the invention
The technical problem that the present invention will solve be for overcome the water inlet of mobile phone in prior art back motherboard circuit damage because of short circuit easily cause canned data to be lost can't recovering, defective that can is unfavorable for the mobile phone heat radiation, the portable terminal that can cut off the electricity supply immediately after a kind of water inlet is provided.
The present invention solves above-mentioned technical problem through following technical proposals:
A kind of portable terminal; Comprise power supply circuits and operating circuit on the mainboard of this portable terminal, its characteristics are that the edge of this mainboard has at least one earthing device; This earthing device links to each other with the negative pole of this operating circuit; This portable terminal also comprises a protective circuit, and this protective circuit is connected between these power supply circuits and this operating circuit, and this protective circuit comprises:
One electromagnetic induction device is used for when this portable terminal electric leakage, producing an induced current;
One amplifier is used to amplify this induced current;
One release is used for being triggered to cut off being connected of these power supply circuits and this protective circuit by this induced current that amplifies.
Preferably, this electromagnetic induction device is a magnet ring, is wound with coil on this magnet ring, and this coil links to each other with this amplifier.
Preferably; This release comprises an electromagnet and a switching device; This switching device comprises a spring and a snap close, and this electromagnet is used under this faradic triggering of amplifying, opening this snap close makes this spring reset to cut off being connected of these power supply circuits and this protective circuit.
Preferably, this earthing device is the dew copper on this mainboard.
Wherein, Dew copper earthing position on this mainboard mainly is distributed in the mainboard marginal position, and (copper all can be revealed as long as top margin has living space in left and right sides side, base; In general; The dew copper position of different mobile terminal maybe be different because the motherboard circuit routing of layout is different, but the position that has living space of making a circle in mainboard week substantially all can be as revealing the copper earth point), the main effect of this dews copper is to do effect such as frame ground when mainboard is made antistatic protection and metal shell is arranged; And in the present invention, utilize this part to reveal copper as earthing device and as the detecting point of whether intaking.Reveal copper earth point communicate with this operating circuit and this power supply circuits negative pole (or can directly be understood as the negative pole in the circuit of whole portable terminal); As long as the place that has living space on the mainboard can be as revealing the copper earth point, because all communicate between each earth point and between earth point and the negative pole.
Positive progressive effect of the present invention is: mobile terminal structure of the present invention is compact; Only increased the function of cutting off the electricity supply automatically when simple part can be implemented in water into; Protected the safety of motherboard circuit and peripheral devices; Thereby can not cause short circuit to cause the data of storage to recover, improve the safety in utilization of portable terminal because of water inlet makes portable terminal.
Description of drawings
Fig. 1 is the structured flowchart of the portable terminal of one embodiment of the invention.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to specify technical scheme of the present invention.
With reference to figure 1, introduce the described portable terminal of present embodiment, comprise power supply circuits 1 and operating circuit 2 on the mainboard of this portable terminal; Wherein, The edge of this mainboard has at least one earthing device (not shown), and this earthing device links to each other with the negative pole of this operating circuit, and this portable terminal also comprises a protective circuit 3; This protective circuit 3 is connected between these power supply circuits 1 and this operating circuit 2, and this protective circuit 3 comprises:
One electromagnetic induction device is used for when this portable terminal electric leakage, producing an induced current;
One amplifier 32 is used to amplify this induced current;
One release 33 is used for being triggered to cut off being connected of these power supply circuits 1 and this protective circuit 2 by this induced current that amplifies.
Specifically, this electromagnetic induction device is a magnet ring 311, is wound with coil 312 on this magnet ring 311, and this coil 312 links to each other with this amplifier 32.
In general, when operate as normal, be not have induced current to produce, only when electric leakage, produce induced current in this coil 312.
More specifically; This release 33 comprises an electromagnet and a switching device (not shown); This switching device comprises a spring and a snap close, and this electromagnet is used under this faradic triggering of amplifying, opening this snap close makes this spring reset to cut off be connected (promptly being the cut state of connection shown in Fig. 1) of these power supply circuits 1 and this protective circuit 3.
In the present invention, this earthing device is the dew copper on this mainboard.
Portable terminal of the present invention through the following action of protective circuit, is cut off the electricity supply after water inlet: at first, reveal the copper position behind the portable terminal inner inlet on the cell phone mainboard and touch the water electric leakage; Then, electric leakage back release breaks off; Finally, operating circuit on the mainboard and power supply circuits break off, and whole mainboard outage has guaranteed that effectively other devices are not burnt on portable terminal mainboard and the mainboard during this portable terminal water inlet instant cut-off is with protection mainboard and periphery.
Mobile terminal structure of the present invention is compact; Only increased the function of cutting off the electricity supply automatically when simple part can be implemented in water into; Protected the safety of motherboard circuit and peripheral devices; Thereby can not cause short circuit to cause the data of storage to recover, improve the safety in utilization of portable terminal, remove the user from yet and lost the trouble that produces owing to data because of water inlet makes portable terminal.
