Abstract
A backplane connector (100) includes a connector housing (1) defining plural openings (14) therethrough, a number of signal terminals (11) arranged in the connector housing, a number of circuit boards (2) retained in respective openings, and a shield member (3). Each circuit board is provided with signal traces (20) and conductive layer (21) on opposite sides thereof. The shield member substantially encloses the connector housing and the circuit boards. The shield member has a number of inwardly projected, resilient tabs (301) stamped therefrom. The resilient tabs are arranged in two staggered rows and each extend between adjacent circuit boards for mechanically and electrically contacting with the conductive layer of a corresponding circuit board to thereby achieve a grounding purpose.
Claims25
An electrical connector for mounting to a printed circuit board comprising:
- a connector housing, said connector housing having plural signal terminals arranged in rows and defining plural parallel openings between adjacent rows of signal terminals;
- a number of parallel arranged circuit boards retained in respective openings of said connector housing, each of said circuit boards having signal traces provided on one side thereof and having a conductive layer coated beside said signal traces and simultaneously coated on the other side of said each of the circuit boards, said signal terminals of said connector housing electrically connecting with said signal traces;
- and
- a metal shield member substantially enclosing said connector housing and said circuit boards, said shield member having a number of resilient tabs, said resilient tabs extending between adjacent circuit boards and electrically contacting with said conductive layer of said circuit boards to thereby achieve a grounding purpose.
An electrical connector adapted for mating with a complementary connector to thereby interconnect a mother board with a daughter board and transmitting massive, high speed data signals therebetween, comprising:
- a number of individual wafers being assembled to each other and defining therebetween a number of receiving openings, each of said wafers comprising a dielectric base, a grounding member and a plurality of terminals arranged in said dielectric base;
- a number of circuit boards respectively received in said receiving openings of said wafers, each of said circuit boards provided with signal traces and grounding traces thereon;
- and
- a metal shield member substantially enclosing said wafers and said circuit boards, said shield member stamping therefrom resilient tabs, each of said resilient tabs electrically connecting to said grounding trace of a corresponding circuit board;
- wherein each grounding member has grounding fingers electrically connecting to said grounding traces of a corresponding circuit board and each of said terminals has a contacting end electrically connecting to said signal traces of said corresponding circuit board, each of said grounding members has grounding pins for electrically engaging with the mother board thus to substantially ground said shield member.
An electrical connector comprising:
- an insulative housing having a plurality of signal terminals arranged in rows;
- plural rows of openings formed between adjacent two rows of signal terminals;
- a plurality of parallel arranged printed circuit boards received in the corresponding openings, respectively;
- a plurality of grounding traces formed on edge portions of the printed circuit boards, respectively;
- and
- a metallic shield enclosing the housing and the printed circuit boards therein;
- wherein
- said shield, includes a plurality of inwardly extending tabs not only dividing the corresponding two adjacent printed circuit boards for mechanical consideration, but also contacting the grounding traces on at least one of said two adjacent printed circuit boards for electrical consideration.
