  • Patent number: 10826211
    Abstract: A card edge connector with an insulative housing includes opposite longitudinal side walls along a longitudinal direction with a receiving slot therebetween in a transverse direction. Each side wall forms a plurality of passageways. A plurality of contacts are respectively received within the corresponding passageways. Each contact includes a retaining section, a contacting section extending from the retaining section into the receiving slot, and a leg extending downwardly from the retaining section out of the housing. Each contact is further equipped with an auxiliary spring beam with an additional contacting section extending into the receiving slot. The contacts are initially linked to a single contact carrier strip so as to be simultaneously inserted into the corresponding passageways, respectively.
