Utility model content
The purpose of this utility model is to provide a kind of mobile phone camera open-short circuit device that can determine fast trouble location, promote maintenance efficiency, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of mobile phone camera open-short circuit device, comprises display section, output, power unit, test section, importation; Described display section is positioned at output top; Described power unit and test section are positioned at output below, and power unit is positioned at left side, test section; Described importation is positioned at below, test section.
In the utility model, described display section comprises LED display lamp, can show the state of camera module function.
In the utility model, described output shows the duty after camera access open-short circuit instrument apparatus.
In the utility model, described power unit adopts four diodes, utilizes the conduct current interaction of diode to be connected into bridge architecture, for a whole set of proving installation provides operating voltage.
In the utility model, described test section can be when camera module be normally worked, and by short circuit respective foot, whether check has other mutual short circuits in pin position.
In the utility model, described importation makes camera module access test section.
In the utility model, described proving installation inside comprises pcb board.
In the utility model, the capacitor filtering of described power unit inside makes output voltage smooth-out, and two utmost point supply voltages output series regulator, makes output voltage more tend towards stability, avoid the flicker of the unstable LED of the causing display lamp of voltage.
In the utility model, when described proving installation is started working, if the lower row LED lamp on pcb board is bright normal, during input circuit access product, being equivalent to provides forward bias to the transistor amplifier of upper row LED lamp, voltage turn-on, and provide operating voltage for LED lamp; Go out for the mutual short circuit of the different pin interdigits of corresponding camera, can cause the transistor amplifier generation reverse bias of lower row LED lamp, voltage cut-off.If the upper row LED lamp on pcb board is bright normal, single lamp goes out and shows corresponding shooting head/foot position open circuit.If LED lamp does not all work, not conducting of proving installation.
Compared with prior art, the beneficial effects of the utility model are: this mobile phone camera open-short circuit device, for the pin position configuration LED lamp of different cameras, can determine fast trouble location, maintenance personal can be keeped in repair targetedly, promote maintenance precision and maintenance efficiency.
