Abstract:
An RJ-receptacle connector comprising:an insulative housing defining a receiving space for receiving a complementary plug connector therein;a plurality of terminals fixed in the insulative housing, each terminal comprising a contact portion extending into said receiving space and a solder tail extending downward from a bottom face of said insulative housing; andan anti-mismating device mounted in the housing, located at an entrance of the receiving space and comprising first and second push portions thereon, when assembled in the housing, adjacent two lateral side walls of the housing and independently and recoverably depressable by the complementary connector, the first and second push portions respectively forming first and second stop portions transversely extending towards each other, without touching each other, for preventing a noncomplementary connector from being inserted into the receiving space, the first stop portion and the second stop portion being separated from each other, whereina distance between the first and the second push portions is greater than a width of the noncomplementary connector, a shortest distance from the first stop portion to an inner surface of the lateral side wall of the housing adjacent the second push portion is less than the width of the noncomplementary connector, and a shortest distance from the second stop portion to an inner surface of the lateral side wall of the housing adjacent tie first push portion is less than the width of the noncomplementary connector; whereinthe anti-mismating device comprises a first spring arm, a second spring arm and a connection plate, the first spring arm and the second spring arms being connected to opposite ends of the connection plate; whereinthe first push portion and the second push portion are defined on the first spring arm and the second spring arm, respectively, and the first stop portion and the second stop portion are defined on a fist beam and a second beam, respectively, wherein the first and second beams extend from the first and second spring arms, respectively, in a direction toward each other; whereinthe anti-mismating device further defines a pair of pads at free ends of the first and second spring arms adapted for receiving a depressing force of the complementary plug connector; whereina bottom wall of the insulative housing defines a pair of recesses, and the connection plate forms a pair of retaining portions at its opposite ends, the retaining portions each extending into a corresponding recess thereby fixing the anti-mismating device to the housing; whereinsaid first and second push portions are perpendicular to the two stop portions, respectively, each push portion having an arced bottom edge projectable into the receiving space.
