Electrical card connector assembly

摘要

An electrical card connector assembly includes an electrical card connector ( 100 ) and a PCB ( 4 ) where the electrical card connector is assembled. The electrical card connector includes a metal shield ( 1 ), an insulating housing ( 2 ) and a terminal module ( 3 ) received in the insulating housing. The insulating housing associates with the metal shield to define a card receiving room. The metal shield forms a base ( 10 ) and a plurality of sidewalls ( 11 ) extending from the base. Each sidewall forms a locking portion ( 111 ) thereof. Each locking portion has a vertical portion ( 1110 ) and a horizontal portion ( 1111 ) extending from a lower end of the vertical portion. At least one of the sidewalls forms an elastic piece ( 12 ) extending along a card insertion/ejection direction and the elastic piece forms a declined portion ( 120 ). The PCB defines a plurality of cutouts ( 44 ) and at least one aperture ( 47 ). The elastic piece is locked with the aperture under a guiding force of the declined portion while the horizontal portions of the locking portions pass through the cutouts and then confront the bottom surface of the PCB.
