Abstract:
A receptacle connector assembly comprising:an insulative housing and a plurality of contacts retained in the housing, the housing defining in a mating face thereof, a first large-dimensioned receiving cavity adapted for receiving a first large-dimensioned plug connector and a second small-dimensioned receiving cavity adapted for receiving a second small-dimensioned plug connector, the first receiving cavity having a channel adapted for receiving a projection of the first plug connector, the housing having a partition separating the first receiving cavity from the second receiving cavity and a sidewall opposite to the partition and adjacent to the first receiving cavity, the housing defining a first cutout and a slit in the sidewall, the housing defining a second cutout extending from a rear face thereof proximate to the partition and an inwardly extending recess communicating with the second cutout; and a pair of keying devices assembled to the housing respectively from the first cutout and the second cutout, the keying devices comprising a pair of respective tail portions respectively retained in the slit and the recess, a pair of respective resilient portions forwardly extending from corresponding tail portions, a pair of respective engaging portions extending from corresponding resilient portions and received in a front position of the first receiving cavity for being pushed away from each other by the first plug connector, and a pair of respective tongues extending from the resilient portions and projecting into the channel for preventing the second plug connector from being inserted into the first receiving cavity; wherein the pair of tongues of the keying devices lie in a common horizontal plane; wherein the pair of engaging portions of the keying devices are spaced a distance smaller than the width of the first receiving cavity but larger than the width of the second receiving cavity.
