Patent ID: 8769178

Claim:
A shock test device, suitable for an expansion slot of a computer system and comprising: a mainboard, having a connecting finger electrically connected to the expansion slot; a structure unit, disposed at the mainboard for simulating a weight and a supporting structure; and a detection module, coupled to at least one pin of the connecting finger for detecting a touch condition between the connecting finger and the expansion slot so as to produce a warning signal, wherein the detection module comprises: a touch-detecting unit, couple to the at least one pin for enabling a touch condition signal when the at least on pin is disconnected from the expansion slot; a latch unit, coupled to the touch-detecting unit for receiving the touch condition signal and enabling and keeping a latch warning signal when the touch condition signal is enabled, wherein the latch unit comprises: a D-type flip-flop having a data input terminal, a clock input terminal and a data output terminal, wherein the data input terminal thereof is couple to a power terminal, the clock input terminal thereof receives the touch condition signal and the data output terminal thereof produces the latch warning signal; and a warning unit, coupled to the touch-detecting unit and the latch unit for producing the warning signal when the touch condition signal is enabled or the latch warning signal is enabled.
