Patent ID: 7422451

Claim:
An electrical connector assembly comprising: a header comprising: an insulating housing defining at least one barrier unitarily extending upwards therefrom; a plurality of header contacts being blade shaped, retained in the housing and arranged parallel to the at least one barrier; and at least one header grounding contact retained on one side of the barriers; and a socket matable with the header, comprising socket contacts and at least one socket grounding contact mated with the corresponding header contact and header grounding contact, and insulating housing defining socket-contact-receiving recesses and socket-grounding-receiving recesses parallel to each other; wherein when the header and the socket are mated with each other, the at least one barrier is inserted into corresponding socket-grounding-receiving recess, and the grounding contacts are electrically connected together before the header contacts and the socket contacts, wherein each of the at least one barrier defines a groove exposed outwards and run through the insulating housing to receive one header grounding contact; wherein the groove is defined on an outer face of the barrier, wherein the header grounding contact and socket grounding contact both are blade shaped and the header grounding contact defines a protrusion projecting outwards for contacting the socket grounding contact, wherein the header grounding contact is resilient and a distance is defined between the contact section of the header grounding contact and the insulating housing for a resilient room of the header grounding contact.
