Description

  The present invention mainly relates to a connector for electrically connecting a board-to-board, a board-to-cable, and the like.

  Conventionally, a connector used for board-to-board connection includes a plug having a protrusion-like fitting convex body provided with a plurality of plug-side contacts, and a fitting groove into which the fitting convex body is inserted. A socket having a plurality of socket side contacts disposed therein is provided, and the contacts are brought into contact and electrically connected by fitting the plug and the socket.

  In this type of connection connector, each of the plug-side contact and the socket-side contact is provided with a joint portion that is in contact with each other in the thickness direction of the conductive metal plate material that constitutes both contacts at the time of fitting. It is known that the holding convex portion protruding from the joining portion and the concave portion formed in the other joining portion are engaged to increase the holding force of the plug with respect to the socket (see, for example, Patent Document 1). ).

  Conventionally, this holding convex part is formed by pressing from an economical point of view, presses the conductive metal plate material that constitutes the joint part with the upper and lower press molds and extrudes a part thereof, then the surface of the extruded part By carrying out finish punching with a press die, a holding convex portion having a trapezoidal cross section is formed with high accuracy.

  However, the conventional technology as described above has a problem that when the plug is repeatedly inserted into and extracted from the socket, the removal force concentrates on the holding convex portion, so that the holding convex portion is worn and the holding force is reduced.

  On the other hand, since the holding convex part 100 is formed by press working, as shown in FIG. 7, the conductive metal plate material constituting the joining part 101 is provided on both sides in the direction intersecting the plug insertion / extraction direction of the holding convex part 100. There is a problem that it is necessary to secure the press margins 102 and 102 of the press die, and accordingly, the width w of the holding projection 100 must be narrowed, and it is difficult to secure the area of the engagement surface 100a.

  Further, in the molding by press working, the limit of the extrusion height is about ½ of the plate thickness, and since the molding is performed by finishing from that state, the protrusion height H of the holding convex portion 100 is limited, There is a problem that the degree of freedom in design is low because the engaging surface 100a must be inclined at a certain angle with respect to the surface of the joint portion 101.

  Therefore, in view of such a conventional problem, the present invention has been made for the purpose of providing a connection connector that can suppress a decrease in plug holding force even when the plug is repeatedly inserted into and removed from the socket. Is.
