PROBLEM TO BE SOLVED: To reduce lowering in the pull-out force of a jack which is caused by repeated insertion/removal to/from a plug. SOLUTION: A jack forms a movable contact strip 60 having a spring property for contacting while pressing a plug during plug connection by folding back one end of an attachment strip 61 attached to a body 70, and restricts excessive displacement of the movable contact strip 60 by raising a projecting strip 65 from the attachment strip 61. A cantilever spring strip 66 is formed for raising the projecting strip 65 on the attachment strip 61, and a clearance 81 is provided for flexing the spring strip 66 between the body 70 and spring strip 66. As a result, the spring strip 66 is flexed at the clearance 81 even when the contact strip 60 comes in contact with the projecting strip 65. This minimizes the amount of wear on two contact surfaces 62A and 65A to reduce lowering in the pull-out force of a jack 10. COPYRIGHT: (C)2008,JPO&INPIT
