Abstract

An electrical connector (1) for use with an electrical card comprises a dielectric housing (11) defining a plurality of passageways (114) each receiving a terminal (12) therein. A pair of supporting arms (14) extends from transverse ends of the housing (11). At least one of the arms (14) defines a retaining recess (141, 24a, 34a, 44a) therein. An EMI shield (13) covers at least a portion of the terminals (12) and includes a base plate (131). At least a retainer (133, 233, 333, 433) is integrally formed on a portion of the base plate (131) for detachably and resiliently engaging with the corresponding retaining recess (141, 24a, 34a, 44a) of the supporting arm (14) of the housing (11).

Claims

1. An electrical connector for use with an electrical card, comprising:

a dielectric housing defining a plurality of passageways each receiving a terminal therein and a pair of supporting arms extending from lateral ends of said housing, at least one of said arms having a retaining recess defined therein and a biasing beam disposed on the retaining recess with a portion of the retaining recess upwardly exposed, the biasing beam extending along the length of the retaining recess; and

an EMI shield attached to the housing shielding at least a portion of said terminals and including a base plate, at least a retainer integrally formed with said base plate and including a downwardly extending tab and a biasing fin extending rearward from an end of the tab at an obtuse angle, the retainer resiliently and detachably engaging with said corresponding retaining recess of said supporting arm of said housing with the tab thereof retained in the exposed portion of the retaining recess and with the biasing fin thereof resiliently received in the retaining recess and laterally exposed right under the biasing beam.

2. The electrical connector as recited in claim 1, wherein said base plate includes at least a retaining barb detachably engaging with a retaining notch defined in a dam portion formed on an upper surface of said housing.

3. The electrical connector as recited in claim 1, wherein a flap portion extends from an edge of said base plate, and said retainer is integrally formed on an end of said portion.
