Connector

A connector, comprising:

• a connector housing including a separation wall with a substantially planar separation wall surface;
• terminal fittings constituting first and second terminal fitting groups penetrating through the separation wall and projecting from the separation wall surface;
• an external matter preventing rib between the first and second terminal fitting groups and projecting from the separation wall surface farther than the terminal fittings, the external matter preventing rib being configured to suppress intrusion of external matter into a space surrounding the terminal fittings, the external matter preventing rib having a first surface facing toward the first terminal fitting group, a second surface facing toward the second terminal fitting group and opposite first and second ends extending between the first and second surfaces;
• a receptacle projecting from the separation wall surface and surrounding the first and second terminal fitting groups and the external matter preventing rib, the receptacle forming a first filling recess surrounding the terminal fittings of the first terminal fitting group and accommodating a potting agent inside and a second filling recess surrounding the terminal fittings of the second terminal fitting group and accommodating the potting agent inside;
• and
• the receptacle further having first and second recesses opposed to one another and facing toward the first and second ends of the external matter preventing rib, the first and second recess forming first and second auxiliary reservoirs communicating with each of the filling recesses, back ends of the auxiliary reservoirs and back ends of the filling recesses being defined by the substantially planar separation wall surface.
