Electrical connector transmitting high frequency signals

An electrical connector comprising:

• an insulative housing including opposite top and bottom surfaces in a vertical direction;
• a plurality of passageways formed in the housing and extending through both the top surface and the bottom surface;
• and
• a plurality of contacts disposed in the corresponding passageways, respectively, each of said contacts including an upstanding plate to retain the contact in the passageway, a spring arm extending upwardly and obliquely from an upper region of the upstanding plate above the top surface with an upwardly bulged contacting section thereof, and a mounting leg extending from a lower region of the upstanding plate around the bottom surface;
• wherein
• an additional layer structure unitarily extends from the spring arm in a compressively folded manner and is intimately positioned on the spring arm in the vertical direction so as to not only reinforce strength of the spring arm mechanically but also lower impedance thereof electrically.

• wherein
• an additional layer structure unitarily extends backwardly from a front end of the spring arm in a compressively folded manner and is intimately positioned upon the spring arm in the vertical direction so as to not only reinforce strength of the spring arm mechanically but also lower impedance thereof electrically.
