Abstract
The utility model relates to a tester for the holder circuit of a cell phone, which consists of an outer shell, a display panel, a transformer, a main circuit board, a display circuit board and a test bench. The tester for the holder circuit of a cell phone is characterized in that: a holder testing circuit of the cell phone, a holder testing circuit detection circuit of the cell phone and a display circuit are equipped on the main circuit board; six NPN type transistors are connected in parallel to form a detection part. When users tests the holder of the cell phone, the users just need to insert a simulation SIM card into the holder of the cell phone and then the users can accurately judge the holder of the cell phone has a malfunction or not. Adopting the tester for the holder circuit of a cell phone can set up and judge the holder of the cell phone conveniently and fast, the labor is saved, the time is saved and it is convenient to operate.
Description
[technical field]
The utility model relates to a kind of mobile phone detector, particularly a kind of mobile phone deck circuit detector.
[background technology]
When the maintenance mobile phone overhauls processing to deck, need to adopt the mobile phone deck is pulled down, see the way whether it breaks, in disassembly process, be easy to cause deck to damage, increased the workload of maintenance process like this fault judgement.
[technology contents]
The purpose of this utility model provides a kind of mobile phone deck circuit detector, by mobile phone deck testing circuit is set, and measuring head is external to the test bench of detector in the mobile phone detector.When the mobile phone deck is carried out test-based examination, need not the mobile phone deck is removed, directly mobile phone deck measuring head is inserted in the mobile phone deck and can test the mobile phone deck.
For achieving the above object, the utility model provides following technic relization scheme: the mobile phone detector is made up of shell, display floater, transformer, main circuit board, display circuit board, test bench, display floater is provided with electric current dial gauge, LCDs, digital display screen; Transformer external power supply and to the power supply of main circuit board and display circuit board, each output information of main circuit board is all exported by display floater, the all logical test seat interface input of each signal input on the main circuit board, it is characterized in that: main circuit board is provided with mobile phone deck test circuit, mobile phone deck test circuit testing circuit, display circuit constitutes, the test section is made of the parallel connection of six NPN type triodes, display circuit is made of six light-emitting diodes, six light-emitting diodes connect the emitter of six NPN type triodes respectively, each NPN type transistor base is connected respectively and is connected to deck test interface on the test bench behind the resistance, be connected with the deck measuring head on the test bench, the simulation SIM card that measuring head is made for distributing by the PCB of mobile phone card constitutes, and six pin of simulation SIM card interface after tested are connected respectively to the base stage of NPN type triode series resistance.
During the testing mobile phone deck, only need simulation SIM card is inserted in the mobile phone deck, when the deck and the cell phone mainboard of mobile phone do not have the time of broken string, electric current just can be mobile to electronegative potential by high potential, thereby make the triode conducting, the driven for emitting lights led lighting.If deck and cell phone mainboard break, then triode can't conducting, and light-emitting diode is not luminous.Can judge accurately thus whether the mobile phone deck has fault.
Adopt this mobile phone deck tester, can make things convenient for promptly the mobile phone deck is provided with judgement, time saving and energy saving, easy to operate.
