Electrical connector having a plurality of absorbing material blocks

An electrical connector electrically connecting a chip module to a printed circuit board, comprising:

• a first insulative housing comprising a plurality of first receiving slots and a plurality of passageways located beside the first receiving slots and spaced out the first receiving slots;
• a second insulative housing comprising a plurality of second receiving slots of the first insulative housing and a plurality of recesses located beside the second receiving slot of the second insulative housing;
• a plurality of terminals received in both of the first receiving slot and the second receiving slot;
• a metal plate located between the first insulative housing and the second insulative housing;
• the electrical connector further comprises a plurality of absorbing material blocks received in the passageways of the first insulative housing, the passageway has an inner surface coated with an metal layer and the absorbing material block is located inside the metal layer, the absorbing material blocks are assembled into the insulative housing from top to bottom, the metal plate interferes with the absorbing material block.

An electrical connector comprising:

• an upper insulative housing defining a plurality of upper receiving slots extending therethrough in a vertical direction;
• a lower insulative housing defining a plurality of lower receiving slots extending therethrough in the vertical direction;
• a plurality of terminals each defining a vertical retention section extending through the corresponding upper receiving slot and lower receiving slot, a lower tail section extending downwardly from the retention section and soldered to a solder ball for mounting to a printed circuit bard, and an upper contacting section extending above an upper surface of the upper housing for engagement with an electronic component;
• a plurality of metallic shielding layer structures alternately arranged among while isolated from the upper receiving slots to shield the neighboring terminals, respectively;
• and
• a metallic grounding plate sandwiched between said upper housing and said lower housing in the vertical direction;
• wherein the metallic shielding layers are electrically and mechanically connected to the metallic grounding plate.
