Abstract: A card carriage bracket has a base. The base has a pair of supporting arms extending from transverse ends thereof. The base including the pair of supporting arms defines a receiving space therebetween. Each supporting arm forms a supporting tab extending toward the receiving space from a bottom edge thereof. At least a clip is integrally formed on one of the supporting arms. At least a first anti-disorientation device is integrally formed at an inner wall of one of the supporting arms, and a second anti-disorientation device is integrally formed at an outer wall of one of the supporting arms.

Abstract: A USB receptacle electric connector consists of a dielectric housing, four conductive contacts and a shielding/grounding shell. The housing has an outer wall and a middle wall located within the outer wall defining four contact passageways. Each contact has a contact portion and a fitting portion received in a corresponding contact passageway, and a terminal portion extending perpendicular to and outside the housing for connection with a printed circuit board. The housing and the shell are dimensioned so that the shell is mounted inside the housing. When the shell is mounted inside the housing, it abuts an inner face of the outer wall of the housing, in which three locking tabs formed by tail portions of three side walls of the shell are fixedly engaged with the housing while middle portions of the three side walls are restrained in three channels defined by the housing.
