Abstract
The utility model relates to a safety alarm IIC (internal integrated circuit) communication card, which comprises a card main body and a printed circuit board arranged in the card main body. A resistance is connected in series between a power input end and a power output end on the printed circuit board through a wire. The resistance is connected in parallel with a buzzer. The safety alarm IIC communication card has an overcurrent protection function. Once a current is large excessively, a power supply can be automatically switched off, a reliable, stable, continuous and rhythmed warning prompt is provided through the buzzer, a user can know the condition at the first time and carry out processing in time so as to achieve the safety effectiveness.
Description
Technical field
The utility model relates to a kind of IIC address card, relates in particular to a kind of security alarm IIC address card.
Background technology
Along with the develop rapidly of large scale integrated circuit, have that interface is few, control mode is simple, the device package form is little, traffic rate also is used in the IC design more and more than the iic bus of advantages such as height.
At present; the IIC address card all inserts electric terminal with socket or lead mode; in case be short-circuited, phenomenon such as overload; still can't protect and recover voluntarily, more can't report to the police, can't the localization of faults; bring very big inconvenience to Communications service; bring great loss to the individual, particularly under unserviced situation, if long-time short circuit, easier the resulting in greater loss of overload.
The utility model content
The technical problems to be solved in the utility model is: a kind of simple in structure, security alarm IIC address card with overcurrent protection and voice prompt function is provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical matters that solves the utility model adopts is: a kind of safe IIC address card, comprise card main body and the printed circuit board (PCB) that is arranged in the card main body, between power input on the described printed circuit board (PCB) and the power output end by the lead resistance of connecting, a hummer in parallel on the described resistance.
The utility model has solved the defective that exists in the background technology; the utlity model has overcurrent protection function; in case electric current is excessive; can cut off the electricity supply automatically; and by hummer provide reliably, stablize, the continuous rhythmical alert prompting that rings; get the information in the very first time, in time handle, to reach safety and effectiveness.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Wherein: 1, card main body, 2, printed circuit board (PCB), 3, power input, 4, power output end, 5, resistance, 6, hummer.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of safe IIC address card, comprise the printed circuit board (PCB) 2 that card main body 1 is interior with being arranged on card main body 1, between the power input 3 on the described printed circuit board (PCB) 2 and the power output end 4 by the lead resistance 5 of connecting, a hummer 6 in parallel on the described resistance 5.
When electric current did not transship in the circuit, the electric current of resistance 5 ends was less, and hummer 6 terminal voltages are crossed low and can not be worked, and therefore cut little ice; When current overload, resistance 5 powers on and flows through greatly, and then hummer 6 can be worked, and sends tweeting sound, reminds the operator to handle.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
Claims (1)
1. security alarm IIC address card, comprise card main body and the printed circuit board (PCB) that is arranged in the card main body, it is characterized in that: between the power input on the described printed circuit board (PCB) and the power output end by the lead resistance of connecting, a hummer in parallel on the described resistance.
