Connector and connector assembly including the same

A second connector coupled with a first connector to form a connector assembly, comprising:

• a second connector insulator including:
• a bottom of a flat plate shape,
• a pair of exterior holding walls configured to protrude from the bottom and extend in parallel to each other along a first direction, and
• a pair of interior holding walls configured to protrude from the bottom and extend in parallel to each other between the pair of exterior holding walls to form an island accommodating space;
• a plurality of first contacts configured to be at least partially exposed to outside the second connector insulator and be spaced apart from each other along the first direction on each of the exterior holding walls and the interior holding walls;
• and
• a plurality of second contacts configured to be at least partially exposed to the outside and be spaced apart alternately from the first contacts on each of the exterior holding walls and the interior holding walls,
• wherein each of the first contacts is configured such that it is a shape of a bent bar having a length in a second direction and supported while wrapping around the one of the exterior holding walls, the bottom, and one of the interior holding walls, and includes an interior mounting section configured to be bent toward the island accommodating space and be exposed to a lower surface of the bottom and is mounted on a substrate while an interior side wrapping around one of the interior holding walls forming an interior molding space S/I upward in the second direction,
• wherein the second connector insulator includes an interior solder overflow preventer configured such that it has a stepped height t1′ protruding from an upper surface of the bottom in the interior molding space S/I in a third direction.

A connector assembly in which a first connector and a second connector are coupled with each other and have a length in a first direction, a width in a second direction, and a thickness (height) in a third direction,

• wherein the first connector comprises:
• a first connector insulator including:
• a pair of holding walls configured to protrude from a bottom of a flat plate and have a length and height,
• an island configured to protrude from the bottom and have a length and a height between the holding walls, and
• a first coupling space and a second coupling space in which interior holding walls of the second connector is accommodated between the island and the holding walls;
• and
• a first contact and a second contact configured to be alternately spaced apart from each other along the first direction on each of the holding walls in a bar shape having a length in the second direction, and
• wherein the second connector comprises
• a second connector insulator including:
• a pair of exterior holding walls configured to protrude from a bottom of a flat plate and have a length and height,
• a pair of interior holding walls configured to protrude with a length and a height between the exterior holding walls while forming an island accommodating space in which the island of the first connector is received, and
• a first accommodating space and a second accommodating space in which the holding walls of the first connector are received between the interior holding walls and the exterior holding walls, and
• a first contact and a second contact configured to be alternately spaced apart from each other along the first direction on each of the exterior holding walls, and interior holding walls in a bar shape having a length in the second direction, and
• wherein the first connector insulator is configured to have an interior solder overflow preventer configured to protrude with a step height t1 from the bottom on an upper portion of the first contact disposed in the first coupling space and the second coupling space, and
• the second connector insulator is configured to have a groove or hole-shaped displacement space S1′ in which the second contact disposed on one of the interior holding walls is elastically deformable, and
• when the first connector and the second connector are coupled with each other, the interior solder overflow preventer of the first connector is accommodated within the displacement space S1′ of the second connector.
