Connector and a method to increase the data transmission rate thereof

A connector comprising a receptacle part and a plug part presents improved performance by changing their structures. The receptacle part includes a plurality of first signal leads and a fixing insulating element. Each of the first signal leads includes a horizontal segment and an inclined segment. The width of the inclined segment is enlarged to be greater than the width of the horizontal segment. A plurality of through holes are created in the fixing insulating element. The through holes allow the inclined segments of the first signal leads exposed from the assembled body of the fixing insulating element and the first signal leads. The plug part includes a plurality of second signal leads, and each of the second signal leads presents one end fixed and connected to a circuit board, and another end contacting the corresponding first signal lead of the receptacle part. Following the direction from the fixed end to the contacting end, a segment of each second signal lead between a first position and a second pos
