Connection contact of an electric connector
A groove is formed on a connecting section surface of an electrically conductive terminal, this groove is subjected to a bending deformation into a convex shape toward the surface side from the backside of a connecting section to form a bent convex section on the surface of the connecting terminal, and edge sections formed on both sides of this groove are positioned on the surface of the bent convex section. When joined to a counterpart connecting section, the groove edge sections are displaced to approach one another to provide a wiping effect on the surface of the counterpart connecting section.
1. A connecting terminal of an electric connector having a plug connector and a receptacle connector comprising:
an electrically conductive terminal consisting of a flat plate for connection of a substrate and another substrate or a cable and a substrate in at least one connector of the both connectors;
a bent convex section being subjected at a part of the connecting section of the electrically conductive terminal to a bending deformation into a convex shape from the backside toward the surface side;
a groove being provided in the center of the convex surface of the bent convex section to have a pair of opposed side walls between which the distance is gradually and continuously enlarged from the bottom to the opening; and
edge sections being formed on both sides of the groove to scratch the surface of the counterpart connecting section for removing foreign substances;
wherein the distance between the opposed side wall pair of the groove constitutes the maximum width in about the middle portion of the longitudinal direction of the groove, and the distance is gradually reduced toward the both end portions according to the variation of the angle of the opposed side wall pair.
2. The connecting terminal of an electric connector described in claim 1 ,
wherein the groove is formed so that a straight-line shape is obtained on the surface of the connecting section.
3. The connecting terminal of an electric connector described in claim 1 ,
wherein the groove is formed so that a connected cross shape is obtained on the surface of the connecting section.
4. The connecting terminal of an electric connector described in claim 1 ,
wherein the groove is formed so that a roulette shape is obtained on the surface of the connecting section.
