Publication number: 20020022412Abstract: An improved electrical contact according to the invention has a U-shaped base having a bottom and two opposing side walls that define a tab-receiving channel. The base has an open forward end for receiving a mating tab terminal and a rearward end with a middle region therebetween. A contact spring is disposed over the bottom and has a bridge which spans the bottom between the opposing side walls in the middle region of the base. A first contact arm extends from the bridge towards the forward end and converges towards the bottom to a first contact point and then diverges to a free end thereby defining a mating tab insertion mouth. A second contact arm extends from the bridge towards the rearward end and converges towards the base to a second contact point that is disposed closer to the base than the first contact point. The bridge is continuous with one of the opposing side walls and includes a free end that is attached to the other opposing side wall.Type: ApplicationFiled: June 26, 2001Publication date: February 21, 2002Inventors: Angel Alonson Merino, Luis Batllo Roses

Patent number: 6293831Abstract: An electric connector comprises a male terminal member and a female terminal member. The female terminal member includes a female portion into which a male portion of the male terminal member can be slidably inserted. The female portion is symmetrical with respect to a longitudinal axis of the female terminal member. The female portion includes a base wall portion, side wall portions which extend upward from lateral ends of the base wall portion, upper wall portions which extend toward each other from upper ends of the side wall portions and bent back portions which extend laterally outward from inward ends of the upper wall portions below the upper wall portions. Front ends of the bent back portions are slanted in a direction away from the longitudinal axis thereby to constitute guide slopes for facilitating insertion of the male portion of the male terminal member into the female portion of the female terminal member.Type: GrantFiled: April 16, 1999Date of Patent: September 25, 2001Assignee: Calsonic Kansei CorporationInventor: Eiji Yamatani

Patent number: 6169961Abstract: An insulation displacement terminal of a high quality and high performance produced by designing the terminal in accordance with data measurement under a condition similar to an actual insulation displacement connection. An extent of insertion of insulation sheath electric cable 6, a distance between a pair of metal blocks 11 and 12 parallel to each other; and a reaction force and a contact resistance acting between cable 6 and spaced metal blocks 11, 12 is measured while inserting cable 6 into a gap between metal blocks 11 and 12 which have a tapered portion on an end of each block. After completing insertion, the extent of insertion of cable &Dgr;2, gap distance WS2, reaction force F2, and contact resistance R2 are obtained and, at the same time, the presence of broken wires (if any) in the cable is determined. These steps are repeated while changing initial gap WS between metal blocks 11 and 12.Type: GrantFiled: July 20, 1999Date of Patent: January 2, 2001Assignees: Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd., Harness System Technologies Research, Ltd.Inventor: Yasushi Saitoh
