Detecting system for detecting connection of connectors and connector assemblies having same

Two connector assemblies, one connector of the two connector assemblies comprising a plurality of first linking lines, and the other connector of the two connector assemblies comprising a plurality of second linking lines corresponding to the plurality of first linking lines, the two connector assemblies comprising:

• a detecting system for detecting the connection between the plurality of first linking lines and the plurality of second linking lines, the detecting system comprising:
• a plurality of first detection switches and a plurality of pull-down resistors, each of the first linking lines being grounded via one of the first detection switches and one of the pull-down resistors in series, wherein terminals of the pull-down resistors connected to the first detection switches are defined as first detecting ends;
• a plurality of second detection switches and a plurality of pull-up resistors, each of the second linking lines being electrically coupled to a high potential via one of the second detection switches and one of the pull-up resistors in series;
• and
• a detection module with a threshold value preset therein, the detection module comprising a detecting module input end electrically connected to each first detecting end and a detecting module output end, the detection module configured for comparing the voltage value at the detecting module input end with the threshold value, and outputting a result via the detecting module output end to determine whether the first linking lines are electrically connected to the second linking lines respectively.
