【技术领域】【Technical field】

本实用新型提供一种检测器，特别是一种可节约检测人员检测时间的检测器。The utility model provides a detector, in particular a detector which can save the detection time of detection personnel.

【背景技术】【Background technique】

检测分析时经常会碰到开机无显的故障，测量电压及相关信号正常，但BIOS没有起动，此时就需要量测中央处理器插座与主板之间的线路(焊点)是否正常，通常作法是将CPU脚座插入CPU SOCKET，再用万用表一一进行测量，此方法因CPUPIN数太多需要很长的时间且很容易出错。When testing and analyzing, it is often encountered that there is no display when starting up. The measured voltage and related signals are normal, but the BIOS does not start. At this time, it is necessary to measure whether the line (solder joint) between the CPU socket and the main board is normal. The usual practice It is to insert the CPU pins into the CPU SOCKET, and then use a multimeter to measure them one by one. This method takes a long time due to too many CPU pins and is prone to errors.

相较于现有技术，当焊点为正常时，分压单元的分压输出端分得一定的电压，可供显示单元指示；而当焊点为异常时，分压单元的分压输出端处于断开状，显示单元不能构成回路，则不可供显示单元指示。检测人员只需从显示单元的指示与否即可以判断焊点的好坏，从而可节约检测人员的检测时间且可提高检测人员判断的准确性。Compared with the prior art, when the solder joint is normal, the voltage divider output terminal of the voltage divider unit gets a certain voltage, which can be indicated by the display unit; and when the solder joint is abnormal, the voltage divider output terminal of the voltage divider unit In the disconnected state, the display unit cannot form a loop, so it cannot be indicated by the display unit. Inspectors can judge whether the solder joints are good or bad only from the indication of the display unit, thereby saving the inspection time of the inspectors and improving the accuracy of judgment of the inspectors.
