<p>A connector for a jack includes four contacts of first, second, third and fourth contacts each having a contact portion and a connection portion, and a housing, to exchange signals and to ascertain whether a plug connector has been inserted into the connector. The third contact substantially U-shaped in cross-section includes a contact piece having a first contact part adapted to contact the plug connector, and a spring piece having an elasticity facing to the contact piece and provided by forming a U-shaped slit in a part of the third contact at a location opposite to the contact piece. When the plug connector is inserted into the connector, the plug connector pushes the first contact part of the contact piece to cause the contact piece to be displaced to the spring piece so that the contact piece pushes the spring piece to cause the spring piece to be displaced toward the housing and at the same time the spring piece pushes the contact piece with each other with the aid of its elasticity. The connector achieves a reliable holding force for the plug connector without scratching it.</p> |
