  • Publication number: 20140120784
    Abstract: A power connector includes an insulative housing, at least a pair of power contacts assembled to the at least one contact-receiving passage. The pair of power contacts are arranged oppositely along an up-to-down direction and cooperating with each other. Each of the at least a pair of power contacts includes a cable termination portion, a contacting portion and an intermediate portion connecting the cable termination portion and the contacting portion. One lateral edge of the intermediate portion is a first latching portion, and the other lateral edge of the intermediate portion is a second latching portion. Thus, when the pair of power contacts are assembled together, the first latching portion of one power contact cooperates with the second latching portion of the other power contact, while the second latching portion of the one power contacts cooperates with the first latching portion of the other power contact to form a hollow frame therebetween along an up-to-down direction.
