Abstract: The invention relates to a card edge connector including an insulating body, a first fixing part, a second fixing part and a plurality of terminals. The terminals are respectively fixing on the first fixing part and the second fixing part in an insert molding manner. The first fixing part and the second fixing part are received and arranged in the insulating body. The first fixing part and the second fixing part respectively has at least one hook. At least one insertion slot is inwardly formed in the insulating body at a position corresponding to the hook; and the hooks are respectively pushed and fastened inwards towards the insertion slots, so that the first fixing part and the second fixing part are assembled and located on the insulating body.

Abstract: A card edge connector is provided, including an insulating body, a plurality of terminals and a pair of ear clips. The plurality of terminals and the ear clips are received and arranged in the insulating body. Each terminal comprises a fixed part, with a contact part formed by extending from one end of the fixed part, and a welding part formed by extending from another end of the fixed part. An extending part is arranged between the fixed part and the contact part, and at least one coupling protrusion is arranged outwards on the fixed part in a protruding way. The coupling protrusion is in interference fit with the insulating body, and the impedance value of each terminal is adjusted by changing the appearance and size of the coupling protrusion, where an optimal area of one of the coupling protrusions is 0.3 mm*0.7 mm.
