ABSTRACT:
An electrical connector for interconnecting a circuit card to a substrate includes a dielectric housing having an elongated slot which is open for receiving an edge portion of the circuit card, and a plurality of contacts which are spaced-apart along a length of the slot. Each of the contacts has a base portion, a lead extending from the housing for connection with a circuit path on the substrate, and a contact arm having a contact surface which extends into the slot for engaging a respective contact pad on the circuit card. An electrical path through each contact is defined from the contact surface to the lead, the electrical path being relatively long when the contact is undeflected. The contact arm has a free end which engages the base portion of the contact during insertion of the circuit card into the slot, wherein a relatively shorter electrical path through the contact is defined from the contact surface to the lead.
