The invention provides an electric connector which comprises an insulator body and a plurality of conductive terminals; the insulator body comprises a top wall, a bottom wall which is arranged corresponding to the top wall, a plurality of side walls which connect the top wall and the bottom wall, and containing grooves which are formed among the side walls and are used for containing the conductive terminals; the containing grooves reach the outer surface of the insulator body in a penetrating manner; each conductive terminal comprises a terminal main body part, a pair of elastic arms which extend along the terminal main body part and a pin; the insulator body is also provided with a holding part; an open slot which is matched with the holding part is formed between the related elastic arms; and the elastic arms are fixedly arranged on the holding part. The electric connector has the beneficial effects that the holding part is matched with each open slot which is formed between one pair of elastic arms, so that the stability of the electric connector can be improved.
