## Abstract

A communication interface comprises a male connector interface and a female connector interface. The male connector interface includes at least one male connector. The female connector interface includes at least one female connector pluggable into the male connector of the male connector interface. An open channel and/or a gap for signal transmission is in the male connector interface and/or the female connector interface. Each of the male connector and the female connector includes a communication line structure, a guiding structure, a support structure, and a protection structure, at least one of which includes a wave absorbing portion configured to absorb an electromagnetic leakage from the male connector interface and/or the female connector interface via the open channel and/or the gap. The communication interface can effectively solve the problem of the leakage of electromagnetic energy inside the communication interface.
