US Patent 7413476 Electrical interconnection with mating terminals

An electrical interconnection (100) includes a plug connector (1) and a receptacle connector (2) mated with each other, each connector including terminals thereof. Every two adjacent terminals (12, 21) of each connector have mating sections (124, 224) disposed in an opposed relationship with each other such that when the plug connector mates with the receptacle connector, mating forces of the mating sections of the plug connector and the receptacle connector are substantially equal to zero. As such, there is no damage happens to an insulative body of the plug connector or the receptacle connector, which is set for holding the respective terminals.
