Electric connector

Abstract

The invention discloses an electric connector. The electric connector comprises an insulating body. A number of terminals are arranged on the insulating body and comprise two signal terminal pairs andtwo grounding terminals positioned between the two signal terminal pairs. A metal shell covers the insulating body, and comprises a neck part extending backwards from the top plate, a first elastic arm, a second elastic arm and a third elastic arm, wherein the first elastic arm, the second elastic arm and the third elastic arm respectively extend backwards from the neck part. The first elastic arm and the second elastic arm are respectively provided with a rightward first contact part. The second elastic arm and the third elastic arm are respectively provided with a leftward second contact part. The first contact part of the first elastic arm and the second contact part of the second elastic arm are staggered. The first contact part of the second elastic arm and the second contact part ofthe third elastic arm are staggered. When the neck part deviates rightwards, the first contact part of the first elastic arm abuts against one grounding terminal rightwards, and the first contact part of the second elastic arm abuts against the other grounding terminal rightwards. When the neck part deviates leftwards, the second contact part of the second elastic arm abuts against one groundingterminal leftwards, and the second contact part of the third elastic arm abuts against the other grounding terminal leftwards.

Description

【Technical field】 [0001] The invention relates to an electrical connector, in particular to an electrical connector with improved high-frequency performance. 【Background technique】 [0002] An existing electrical connector is used to connect a pair of mating components. The electrical connector has an insulating body, a plurality of terminals accommodated in the insulating body, and a shielding shell covering the insulating body. body, the top end of the insulating body is recessed toward the bottom end to form a docking cavity for accommodating the docking element. The plurality of terminals are arranged in two rows on both sides of the docking cavity, and each row of terminals includes a plurality of signal terminals and a plurality of ground terminals arranged in the left and right directions, wherein the ground terminals are located on two sides of the docking chamber. Between the signal terminals, each of the ground terminals is provided with a welding portion, and a m...

[0003] However, since the width of the ground terminal in the left-right direction is relatively small, and the first contact portion is aligned with the second contact portion, the first contact portion and the second contact portion are aligned in the left-right direction. The distance above is relatively small, and it is easy to make the thickness of the punch punching the gap between the first contact part and the second contact part in the left and right direction smaller than that used to form the first contact part and the second contact part. The thickness of the metal sheet of the contact part makes the punch prone to breakage when forming the first contact part and the second contact part. When th
