  • the first connecting portion 41 of the first terminal 14 may be referred to as a tip side or head side bridge of the first terminal 14.
  • the second connecting portion 42 may be referred to as a base side or foot side bridge of the first terminal 14.
  • the third connecting portion 43 may be referred to as an intermediate bridge. As shown in FIG.
  • the discrete bridge including the first connecting portion 41, the second connecting portion 42, and the third connecting portion 43 may connect the pair of elastic displacement portions 30 of the first terminal 14 so that the plate surfaces 31 of the pair of elastic displacement portions 30 of the first terminal 14 extend on the same imaginary plane and each end surface of the pair of elastic displacement portions 30 is perpendicular to the same imaginary plane.
  • a structure in which a pair of elastic displacement portions 30, each of which may be a flat needle-like or slender flat flexible bar, are connected in parallel by multiple discrete bridges is advantageous in reducing the weight of the first terminal 14 and in maintaining the pair of contact portions 34 (long convex curved surfaces) of the first terminal 14 in a directly opposed state, for example, in maintaining the shortest opposing distance between the pair of contact portions 34.
  • the folded portion 33 may be referred to as a 180-degree folded portion, may have a crushed U-shape when viewed from the Z-axis direction, the tip end 33b of the folded portion 33 may be parallel to and adjacent to or in contact with the base end 33a, and may have a convex curved surface or an outwardly curved surface that functions as a contact portion 34.
  • the convex curved surface (contact portion 34) of the folded portion 33 is continuous with the plate surface located in the offset direction of the offset portion 36, of the pair of plate surfaces 31 that face each other in the plate thickness direction of the elastic displacement portion 30.
  • the bending portion 61 may have an open U-shape when viewed from the Z-axis direction, the base end and tip end of the bending portion 61 may be perpendicular to each other or point in different directions, and may have a convex curved surface or an outwardly curved surface that functions as a contact portion 62. As shown in FIG. 6, the convex curved surface (contact portion 62) of the bending portion 61 may be continuous with one of the pair of plate surfaces 31 of the elastic displacement portion 30 that is located in the offset direction of the offset portion 36.

Abstract

L'invention fournit une borne qui tout en garantissant une pression de contact vis-à-vis d'une borne homologue, permet d'inhiber le pelage d'un film de revêtement de la borne homologue. Une première borne (14) formée par usinage à la presse à partir d'un substrat de forme plate selon un mode de réalisation de l'invention, est équipée d'une paire de parties déplacement élastique (30) de forme plate, et d'une partie couplage (40) reliant les parties déplacement élastique entre elles. Chacune des parties déplacement élastique (30) possède une partie connexion (34) qui est connectée par sa force élastique à la borne homologue insérée entre les parties déplacement élastique (30). Chacune des parties déplacement élastique (30) prend une forme plate qui présente une face plate (31) et une face bord (32). Les parties déplacement élastique (30) sont agencées en parallèle de sorte que leurs faces bord (32) s'opposent entre elles. Chacune des parties déplacement élastique (30) possède une partie repli (33) constituée d'une partie courbe formée par prolongement et courbure depuis les faces bord (32). Les parties connexion (34) sont formées par une partie de la face plate (31) au niveau de la partie repli (33).
