Connector and connector assembly comprising same

A connector assembly used with a plug connector and a receptacle connector coupled to each other,

• wherein the plug connector comprises:
• a first insulating body including:
• a first bottom having a flat-plate shape,
• a pair of first outer support wall configured to protrude from the first bottom and extend in parallel to each other along a first direction (X-axis direction),
• a pair of first hold down retaining walls configured to be provided at both ends of the pair of first outer support walls in the extension direction, respectively, and
• a first inner support walls configured to extend in parallel between the pair of first outer support walls;
• and
• a plurality of contacts and configured to be spaced apart from each other along the first direction (X-axis direction) on each of the pair of first outer support walls,
• wherein the receptacle connector comprises:
• a second insulating body including:
• a second bottom configured to be spaced apart from the first bottom to face each other,
• a pair of second outer support wall configured to protrude from the second bottom and extend in parallel to each other along the first direction (X-axis direction),
• a pair of second hold down retaining walls configured to be provided at both ends of the pair of second outer support wall in the extension direction, respectively,
• a pair of second inner support wall configured to extend in parallel between the pair of second outer support wall and be provided with a coupling space therebetween, and
• a pair of second inner walls configured to be provided at both ends of the pair of second inner support walls in the extension direction, respectively;
• and
• a plurality of contacts and configured to be spaced apart from each other along the first direction (X-axis direction) on each of the pair of outer support walls, respectively,
• wherein the coupling of the plug connector and the receptacle connector is configured to be achieved by the first inner support wall of the plug connector entering the coupling space of the receptacle connector.
