Electrical connector contact element having multi-contact points to come into contact with a single mating contact element with independent contacting forces

An electrical connector comprising an insulator (230) fixing a contact element (51), said contact elements (51) being made of an electroconductive elastic plate and comprising a fixing portion (53) fixed to said insulator (230) and having a first end, an elastic portion (55, 57) with a second end connected to the first end of said fixing portion (53) and having a third end opposite to the second end, said elastic portion (55, 57) being formed with at least one slit (71) extending from said third end towards the second end to form a plurality of elastic finger portions (101, 103), and a plurality of contact points (91, 93) formed on said finger portions (101, 103), respectively, for coming into contact with a common mating contact element, wherein said plurality of elastic portions (101, 103) have widths, respectively, which are at least partially different from each other,

• wherein said elastic portion (55, 57) comprises:
• an elastic arm portion (55) having said second end connected to said first end of said fixing portion (53) and being smoothly bent with a C-shape curve towards said fixing portion (53), said elastic arm portion (55) having a fourth end portion opposite to said second end thereof, said fourth end portion comprising a plurality of separate pieces (81, 83) separated by said at least one slit;
• and
• an elastic contact portion (57) comprising said elastic finger portions (101, 103) connected to said separate pieces (81, 83), respectively, said elastic contact portion (57) being smoothly bent with a U-shape curve in a direction opposite to said C-shape curve and being further bent with a V-shape curve in a direction of said U-shape curve, said contact points being formed on the V-shape curve.
