The present invention relates to a connector with a coupler. More specifically, the present invention relates to an EIA connector having an integrated coupler and improving coupler directivity. In addition, the present invention relates to an EIA connector for preventing foreign matter from entering the coupling space. A connector according to an embodiment of the present invention includes a body having a hollow pierced in the front-rear direction; A connector pin installed inside the hollow; Two insulating supports for supporting the connector pin in the hollow and spaced a predetermined distance to define a coupling space; A coupler cover which is coupled to one side of the body and on which a coupling line for inducing a part of the signal passing through the connector pin is disposed; And a dielectric block that spatially separates the coupling line arrangement space in which the coupling line is disposed and the coupling space.
