Electrical connector with power contacts designed to handle instantaneous inrush current

Abstract

An electrical connector () comprises an insulative housing including a mating tongue () exposed in a mating port (), and three type contacts. The mating tongue has a front face () thereof. The three type contacts include two power contacts () being on two opposite side regions of the mating tongue, three signal ground contacts () located between said two power contacts, and two pairs of signal contacts () each located between the corresponding two adjacent signal ground contacts. One of the two power contacts () extends much closer to the front face of the mating tongue than the other () of the two power contacts. This arrangement of two different-lengths has the ability to handle the instantaneous inrush current through the former power contact, i.e. the pre-charge power pin.
