Abstract: An electric connector includes a socket and a plug. The socket includes a first insulating block and a first terminal and the first insulating block has a positioning notch and a positioning hole. The plug includes a second insulating block and a second terminal, and the second insulating block has a plug end and a fool-proof block protruded from the plug end and extended towards the socket. The second insulating block includes a positioning hook arm formed on the other opposite side. When the second insulating block is plugged into the first insulating block, the fool-proof block is stopped at the positioning notch, and the positioning hook arm is latched into the positioning hole, such that the first terminals are electrically coupled to the second terminals, so as to assure a proper connection of the electric connectors and prevent damages caused by improper connection of the electric connectors.

Abstract: An electrical connector adapted for electrical connection with an electronic card. The electrical connector includes a plurality of conductive terminals, each of the terminals being bent and having a fixed segment, and a connecting segment bent from one end of the fixed segment, and resilient segment bent from the other end of the fixed segment at one end thereof. Further there is a contact segment bent from the other end of the resilient segment and having an uneven surface that serves as a wiping unit and that is adapted to move over the electronic card to wipe out dust and contaminants from the electronic card when the electronic card is assembled to the electrical connector.

Abstract: A card edge connector includes an insulating body having opposite lateral side frames for mounting respectively two metallic pieces thereon, and terminals mounted in the insulating body and coupled to a circuit board. When an insertion side with conductive terminals of an electronic card is inserted into an insertion groove in the insulating body, the conductive terminals contact respectively contact portions of the terminals extending into the insertion groove. Each metallic piece includes first and second resilient arms extending from a base, and a carved metallic piece extending from the first resilient arm. When the insertion side of the electronic card is inserted into the insertion groove, each lateral side of the electronic card is clamped between the anchoring member and the second resilient arm of a corresponding metallic piece, and is formed with a notch engaging a projection of the second resilient arm of the corresponding metallic piece.

Abstract: A manufacturing process for a plurality of conductive terminals, comprising the steps of: (1) punching a flat metallic plate to form a carrier and a plurality of spaced-apart terminal bodies, and blanking each of the terminal bodies to form an uneven surface, so that the uneven surface serves as a wiping unit; (2) bending each of the terminal bodies to form a curved contact segment, a resilient segment, a fixed segment, and a connecting segment, such that the uneven surface is located at the contact segment; (3) assembling the bent terminal bodies to an insulating housing; and (4) cutting and removing the carrier from the terminal bodies so that the terminal bodies disposed on the insulating housing constitute the conductive terminals.
