Abstract

A board-to-board electrical connector comprising a male connector including a first insulating base, a plurality of male terminals, each said male terminal having a male contact and a male stator; a female connector including a second insulating base, a plurality of female terminals, each female terminal having a female lead and a female contact extending from the female lead in an bending direction for engagement with said male contact, and a female stator which engages with said male stator, the male contact is a closed ring in shape with at least a protrusion formed at its outside surface, which is restrained in the receiving cavity formed between the first convex of the female contact and the second convex set abreast to the first convex, and the outside surface of which contacts with the first convex and the second convex respectively, the first convex and the second convex being formed with the arm of the female contact bended forth and then back, the protrusion engaging with the first convex or the second convex in a locking manner. The electrical connector disclosed is small in size and the connection of the male terminal and female terminal is reliable.

Dependent claims

A board-to-board electrical connector comprising:

a male connector (1), including a first insulating base (10), a plurality of male terminals (11) integrally molded with said first insulating base (10), each male terminal (11) having a male contact (111), and a male stator (100) disposed at each end of said first insulating base (10);
and
a female connector (2), including a second insulating base (20), a plurality of female terminals (21) received in said second insulating base (20), each female terminal (21) having a female lead (210) and a female contact (211) extending from said female lead (210) in an bending direction for engagement with said male contact (111) to make circuit on, and a female stator (200) disposed at each end of said second insulating base (20), which engages with said male stator (100);
is characterized in that,
each male contact (111) is shaped in a closed ring with at least a protrusion (113) formed at its outside surface, which is restrained in a receiving cavity (2112) formed between a first convex portion (2110) of said female contact (211) and a second convex portion (2111) set abreast to the first convex portion (2110), outside surface of said male contact (111) contacting with said first convex portion (2110) and said second convex portion (2111) respectively, wherein the first convex portion (2110) and the second convex portion (2111) each having an arm are formed form said female contact (211) by bending forth and then back, said protrusion (13) engaging with said first convex portion (2110) or said second convex portion (2111) in a locking manner.
