Abstract
A connection detection device and a connection detection method for detecting a connection state between a first connector and a second connector are provided. The first connector includes detection pins. The second connector includes loop pins corresponding to the detection pins. The connection detection device includes a bias voltage generator, a detection circuit, and a processor. The bias voltage generator applies a reference bias voltage to the detection pins. The detection circuit detects bias values on the detection pins. When each bias value is shifted to a first bias value based on a connection loop formed between the detection pins and the loop pins, the detection circuit provides a first detection signal. When at least one of the bias values is not shifted to the first bias value, the detection circuit provides a second detection signal. The processor provides an alarm signal in response to the second detection signal.
