Connection structure of connector capable of managing a large electric current
A socket connector includes a housing mounted on a substrate, a plurality of socket terminals that is held by the housing. The plurality of socket terminals is, on one end side thereof, conductively connected to a single connection pad provided in a circuit pattern of the substrate, and is, on the other end side thereof, conductively connected to a plug terminal that is to be a connection mate. Each of the socket terminals includes a substrate connection portion that is fixed to a connection pad, a contact portion that comes into conductive contact with the substrate, and a connection piece portion that connects the contact portion and the substrate connection portion to each other. The connection piece portion including a plurality of branched pieces forming conductive paths that connect, in a parallel manner, the contact portion and the substrate connection portion splits an electric current in a parallel manner.
1. A connection structure of a connector, comprising:
a connector that conductively connects a connection object to a substrate;
the connector including
a housing, and
a plurality of terminals held by the housing; and
the plurality of terminals each including
a substrate connection portion that comes into conductive contact with a common connection pad provided on the substrate,
a contact portion that comes into conductive contact with the connection object, and
a plurality of branched pieces connecting, in a parallel manner, each substrate connection portion and the corresponding contact portion,
wherein the plurality of branched pieces is disposed in a parallel manner while leaving a space for releasing heat in which at least the plate area of one branched piece can be disposed in a horizontal manner between one branched piece and the other branched piece.
2. A connector, comprising:
a housing mounted on a substrate;
a plurality of terminals held by the housing; and
each of the terminals including
a substrate connection portion that conductively connects to a common connection pad provided on the substrate,
a contact portion that comes into conductive contact with a common connection object that is a connection mate of the connector, and
a plurality of branched pieces forming parallel conductive paths that connect each of the substrate connection portion and the corresponding contact portion to each other,
wherein the plurality of branched pieces is disposed in a parallel manner while leaving a space for releasing heat in which at least the plate area of one branched piece can be disposed in a horizontal manner between one branched piece and the other branched piece.
3. The connector according to claim 2 , wherein
the contact portion includes a plurality of branch contact portions that form parallel conductive paths.
