RELATED APPLICATIONS

This application claims priority to Chinese Application No. 201910630324.6 filed on Jul. 12, 2019, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to a connector assembly, and particularly relates to a connector assembly having a heat sink.

BACKGROUND

Chinese invention patent application publication No. CN101930100A (corresponding to U.S. Pat. No. 7,794,241) discloses a connector, a guide frame of the connector includes a metal body which is formed by stamping and defines a shell having a top wall, a bottom wall and side walls. A receptacle connector is mounted in a rear segment of a cavity of the guide frame. The top wall of the guide frame has a large opening overlaying the cavity, the cavity accommodates a heat sink. The heat sink includes an engagement surface mounted into the cavity, the engagement surface of the heat sink physically contacts and abuts against an inserted mating module. The top wall of the guide frame includes a front portion, a rear portion and opposed lateral portions which define a perimeter of the opening. The portions of the top wall also define a seat of the heat sink. When the heat sink is mounted over the opening, the top wall supports the heat sink. The rear portion of the top wall includes a front stop in the form of a tab extending downwardly, the tab slightly protrudes inwardly into the opening and downwardly into the cavity. The front stop fixedly configured in the top wall engages a rear surface of the mating module to prevent the mating module from rearwardly passing through the guide frame beyond a specified distance. However, because the rear portion of the top wall is still present above the receptacle connector, the heat sink is positioned on a top face of the rear portion of the top wall, that is to say, the heat sink and the receptacle connector are still spaced apart by the rear portion of the top wall, which will affects heat dissipating efficiency. And because of presence of the rear portion of the top wall, although the engagement surface of the heat sink enters into the cavity via the opening, a bottom face of the heat sink at the rear portion of the top wall must be raised to above the top face of the rear portion of the top wall, which results in that the bottom face of the heat sink must have a height difference with respect to a part thereof extending rearwardly, particularly in a heat sink including a heat pipe, the heat pipe also is correspondingly bent.
