The testing staff can judge the quality of weld spot from the instruction of display unit, thereby saving the testing time of testing staff.
Description
[technical field]
The utility model provides a kind of detecting device, particularly a kind of testing staff's detecting device of detection time of saving.
[background technology]
Run into start through regular meeting during check and analysis and do not have the fault that shows; measuring voltage and coherent signal are normal; but BIOS is starting not; just need this moment the circuit (solder joint) between measurement central processing unit socket and the mainboard whether normal; usually the practice is that the CPU runners is inserted CPU SOCKET; measure one by one with multimeter, the method needs long time too much because of the CPUPIN number and is easy to make mistakes again.
[summary of the invention]
Fundamental purpose of the present utility model is to provide a kind of testing staff of saving the detecting device of detection time.
For reaching above purpose, the utility model provides a kind of detecting device, is inserted in the central processing unit socket and is used to detect some solder joints between central processing unit socket and the mainboard, and this detecting device comprises a grafting body that this grafting body is plugged in this central processing unit socket; And should be provided with a power supply unit and plurality of detection branch road by the grafting body, and these detection branch comprise a partial pressure unit and a display unit respectively, wherein, the input end of this partial pressure unit electrically connects this power supply unit, and the output terminal of partial pressure unit electrically connects a solder joint; One end of display unit electrically connects this power supply unit, and the other end of display unit electrically connects the output terminal of partial pressure unit.
Compared to prior art, when solder joint for just often, the dividing potential drop output terminal of partial pressure unit is got certain voltage, can be for display unit indication; And when solder joint when being unusual, the dividing potential drop output of partial pressure unit is in disconnecting shape, and display unit can not constitute the loop, then can not be for the display unit indication.The testing staff only needs whether promptly can judge the quality of solder joint from the indication of display unit, thereby can save testing staff's detection time and can improve the accuracy that the testing staff judges.
[description of drawings]
Fig. 1 is the block scheme of the utility model detecting device.
Fig. 2 is the circuit diagram of the utility model detecting device.
[embodiment]
See also shown in Figure 1, the utility model detecting device is inserted in the central processing unit socket 200 and is used to detect some solder joints 201 (this central processing unit socket 200 is welded in mainboard 100) between central processing unit socket 200 and the mainboard 100, under the normal condition, there is the impedance of a normal size between the earth terminal of each solder joint 201 and mainboard 100, and under abnormal conditions (during for example empty the weldering), exist infinitely-great impedance between the earth terminal of each solder joint 201 and mainboard 100.
And this detecting device comprises a grafting body 300, and this grafting body 300 is plugged in this central processing unit socket 200; And should be provided with a power supply unit 31, a switch element 32, plurality of detection branch road 33 by grafting body 300.Wherein, this power supply unit 31 can be an accumulator, also can be a transformer.Wherein, the quantity of detection branch 33 is corresponding with the quantity of solder joint 201, and these detection branch 33 comprise a partial pressure unit 331 (this partial pressure unit 331 can be a fixed resistance) and a display unit 332 respectively, wherein, one end of this switch element 32 electrically connects the input end of the other end electric connection partial pressure unit 331 of these power supply unit 31 these switch elements 32, and the output terminal of partial pressure unit 331 electrically connects a solder joint 201; One end of display unit 332 electrically connects the input end of this partial pressure unit 331, and the end in addition of display unit 332 electrically connects the output terminal of partial pressure unit 331.Especially, also switch element 32 can be saved.
See also shown in Figure 2, comprise a resistance 3321 and a light emitting diode 3322 in this display unit 332, and an end of this resistance 3321 electrically connects this power supply unit 31, the other end of this resistance 3321 electrically connects the positive pole of this light emitting diode 3322, and the negative pole of this light emitting diode 3322 electrically connects the output terminal of partial pressure unit 331.When solder joint for just often, the dividing potential drop output terminal of partial pressure unit 331 is got certain voltage, can for light emitting diode 3322 normally luminous; And when solder joint when being unusual, the dividing potential drop output of partial pressure unit 331 is in disconnecting shape, and the circuit at light emitting diode 3322 places can not constitute the loop, then can not be normally luminous for light emitting diode 3322.Thus, during detection, as long as find corresponding solder joint according to the position at non-luminous light emitting diode 3322 places.
