Abstract:
A shielded surface-mount electrical receptacle connector adapted to be mounted on a circuit board and adapted to mate with a shielded electrical plug connector, the shielded surface-mount receptacle connector comprising:a plurality of contact terminals, each having a contact portion extending in a longitudinal direction, and a solder tail portion extending from said contact portion in a first direction transverse to said longitudinal direction;a dielectric terminal mounting seat including a mating portion for mounting said contact portions thereon and a terminal aligning portion which has upper and lower major mounting surfaces which are opposite to each other in said first transverse direction, said solder tail portions of said contact terminals passing through said upper and lower major mounting surfaces and adapted to be in electrical contact with the circuit board, said terminal aligning portion further having a proximate end face and a distal end face relative to said mating portion, a pair of lateral walls extending between said proximate and distal end faces and opposite to each other in a second direction transverse to said first transverse direction, and a pair of tongue engaging groove units formed in said lateral walls, respectively, and extending from said proximate end face towards said distal end face and crossing over at least one of said solder tail portions;a metal shield disposed to shield said contact portions and said solder tail portions from electromagetic interference in said second transverse direction, said metal shield including a tubular shell with first and second open ends opposite to each other in said longitudinal direction, said tubular shell including a first tubular portion enclosing and cooperating with said mating portion to define an annular receiving space therebetween adapted to accommodate the shielded electrical plug connector when the latter is inserted thereinto via said first open end, and second tubular portion extending integrally from and in alignment with said first tubular portion and enclosing said terminal aligning portion, said second tubular portion having at least one pair of opposite side walls spaced apart from each other in said second transverse direction and extending in said first transverse direction to form a pair of spaced apart lowermost portions facing said lateral walls, respectively, at least two pairs of mounting legs each pair being spaced apart from each other in said longitudinal direction by a bendable portion with a length corresponding to a respective one of said tongue engaging groove units and extending in said first transverse direction from said lowermost portions of said side walls and adapted to be inserted into the circuit board, and a pair of engaging tongues each being formed by punching and bending said bendable portion of a respective one of said lowermost portions of said side walls such that said engaging tongues extend toward each other in said second transverse direction to engage said tongue engaging groove units of said lateral walls, respectively, so as to prevent said lowermost portions of said side walls of said second tubular portion from being undesirably thrust away from said terminal aligning portion.
