Abstract: In some embodiments, an electrical connector comprises a male body and a female body. The male body comprises a first insulating base and a plurality of male terminals. Each male terminal includes a male contact. The female body comprises a second insulating base and a plurality of female terminals. Each female terminal includes a female contact arranged to engage a male contact so as to form a circuit. The male contact is formed with a protrusion extending from a side surface. The female contact is bent to form an arc-shaped convex surface that abuts the male contact, and engages the protrusion of the male contact.

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 sec

Abstract: In some embodiments, a coaxial electrical connector comprises a terminal member, an insulator, and a metallic shell. The terminal is located in the insulator, and the insulator is located in the metallic shell. The insulator has a foldaway extending member which has a groove. When the wire stock is inserted and placed in contact with the terminal, the extending member is bent toward the wire and the groove clips the wire tightly. Thus, the electrical connector ensures that the wire and the terminal are electrically connected.
