Patent ID: 7300292

Claim:
A plug type connector having: terminals which are to be inserted into an internal space of a jack type connector that are elongated laterally and serve as a counter connector, through an insertion/extraction port that is elongated laterally and has a rectangular shape, whereby said terminals are caused to be respectively in contact with said internal terminals of said jack type connector; a butting portion which butts against a receiving portion of said jack type connector to restrict a degree of insertion of said terminals with respect to said internal space; and protrusion portions which project in front of said terminals, and which, when said terminals are inserted into said internal space of said jack type connector through said insertion/extraction port, push open a shutter which closes said insertion/extraction port of said jack type connector, wherein said protrusion portions have a shape which, in accordance with a tilting motion of said plug type connector, caused by prying said plug type connector in a thickness direction, allows said protrusion portions to escape to the outside of said internal space through said insertion/extraction port without changing an initial shape of peripheral wall faces of said internal space, and an initial shape of said shutter which is opened by said protrusion portions, and said internal terminals of said jack type connector are placed outside loci of movement in which said protrusion portions escape to the outside of said internal space through said insertion/extraction port.
