Electronic installation via the charging of signal input
Technical field
The invention relates to a kind of electronic installation, particularly relevant for a kind of multifunction electric meter that uses the signal detection terminal with charging via the charging of signal output/input terminal.
Background technology
Existing electronic installation generally all needs the supply of power supply just can carry out its work.The for example mobile phone used of Mobile Communications, beeper, personal digital assistant, multifunction electric meter, oscillograph, digital camera, digital camera, sound equipment, recording pen, global position system etc. with oneself.Perhaps, the function of these electronic installations all is not quite similar, but all needs the supply of power supply just can work.Power supply be supplied with many modes, the jettisonable of use battery is arranged, or chargeable battery.A kind of rechargeable battery of main flow is a lithium battery.
The structural representation of general electronic installation, shown in Figure 1A, an electronic installation 100 comprises charge storage element 101, electronic component 102, indicator elment 103, switch 104, and input/output terminal 105.Charge storage element 101 mainly provides electronic component 102 power supplys, and its charge path mainly is to charge via charger 107 independently.General charge storage element 101 can use storage battery, or above-mentioned lithium battery.This class charge storage element 101 all can have independently charger 107 in design.
With universal electric meter 110 expressions, it has indicator elment 111 to a kind of electronic installation shown in Figure 1B, switch 112, function choosing-item 114,115, the input and output terminal 116 of detection signal.The indicator elment 111 main states that show electronic component can be designed to be pointer or liquid crystal digital demonstration etc.The charge storage element of the electronic installation of this class is when charging, shown in Fig. 1 C, needs independent battery 121 is taken off and inserts in the charger 122.
The structural representation of another kind of electronic installation, shown in Fig. 2 A, an electronic installation 200 comprises charge storage element 201, electronic component 202, indicator elment 203, switch 204, input/output terminal 205, and charger 207.The charge path of charge storage element 201 mainly passes through charging terminal 207.Compare with previous example, shown in Fig. 2 B, electronic installation 210 itself provides charging terminal 217.Just the user does not need to take off charge storage element or battery, and then goes for independently that charger charges.Two compare, no matter be to charge via charger 107 or charging terminal 207, the charging process of charge storage element all is via independent pathway.
If the built-in charging circuit of traditional electric equipment products is with the battery charge to inside, need via independent DC JACK or Molex splicing ear, yet these charging terminals or socket all are special purposes, as Fig. 1 C, and Fig. 2 B shown in.For example power supply supply or charging for the product that safety is had relatively high expectations, all needs to handle especially at these charging terminals or socket.
Though universal electric meter has charge storage element, switch and output/input terminal etc. at present, be somebody's turn to do output/input terminal, only do the output and the input of signal, fail to have the path that charge function uses.Shown in Figure 1B, ammeter 110 has indicator elment 111, switch 112, signal input/output terminal 116.
Existing charging terminal or socket all are special purposes, i.e. charging or power supply supply, present such charge member, separate with the main consuming body as charging terminal and socket are most in design, dispose charger (Fig. 1 C) in addition as need, or the different charging terminal of additional configuration, promptly this charging terminal only has the special purpose (Fig. 2 B) of charging.
These charging modes all are to be used to not have dangerous product of voltage or environment in addition, for industrial environment, its operating voltage all is higher than the voltage of family and school's use, so its safety also requires strictness relatively need reach the CAT-III.600V grade at least, if use these charging terminals or socket, its voltage withstand class of originally creeping distance, protection circuit and fuse all need be brought up to CAT-III.600V or relative safety grade; So its lower grade of charging modes safety of electric equipment products that general family expenses or school use, and be not suitable for industrial environment.
Summary of the invention
In the foregoing invention background, problems and shortcoming that the splicing ear that classic method provided only has special purpose and produced, the main purpose of the present invention is to utilize the original terminal that inputs or outputs to come the charge storage element of inside is charged, and does not need additional outlet or charging terminal.
Another object of the present invention is to product, can promote the safety of electronic product, thereby significantly promote user's safety guarantee built-in charge storage element and circuit.
Another purpose of the present invention is that the user does not need to differentiate signal input and output terminal and charging terminal, can increase the convenience of use.
A further object of the present invention is to make the volume minimization of electronic product.
Again, the present invention need not do different processing with charging terminal for the signal input and output terminal of difference in functionality for electronic product.
According to the above purpose, the invention provides a kind of multi-functional charge path, come the rechargeable battery of inside is charged via the original terminal that inputs or outputs, and do not need the additional outlet terminal, this invention can be used for any electronic installation that needs charge inside, help the just property used, must additionally not increase charging terminal or charger etc. again, especially to the desired safety of the electronic product that is used in industrial environment, also can reach its regulation, so also be increased in the security that industrial environment is used.
The present invention also provides any hand held, the portable or various testing tool type of desktop, comprises products such as universal electric meter, program calibrating device, program ammeter/universal electric meter, oscillograph.No matter utilize any kind of mechanical switch or electronics commutation circuit to make original I/O or control/detection or measurement/generation signal terminal, become the path of charge inside battery; Or the charge path of charge inside battery becomes I/O or control/detection or measurement/generation signal terminal.
