A coaxial cable connector includes a coupler portion configured to engage an interface port and having a rearward facing coupler surface, a body portion having a forward facing body surface, and a post portion having a rearward facing post surface. The post portion is configured to engage the body portion to form a space between the rearward facing post surface and the forward facing body surface when the connector is assembled. A grounding portion has a post contact portion configured to be located rearward from the rearward facing coupler surface so as to extend in the space when the connector is assembled and when the coupler portion engages the interface port so as to maintain physical and electrical grounding contact with the rearward facing post surface during operation of the connector, and a coupler contact portion configured to contact the rearward facing coupler surface during operation of connector.
