Problems solved by technology
[0005] In this electrical connector, the metal shell is in contact with the ground terminal to realize the shielding function, but the metal shell only forms a single contact with the ground terminal through the abutment elastic piece protruding from the top plate, and the contact area is relatively small. Small so that the shielding effect is not obvious, affecting the high frequency performance of the electrical connector

The invention discloses an electric connector, which is used for being connected with a connecting piece. The connecting piece is provided with ground conductive pieces, signal conductive pieces and an upper shielding part. The electric connector comprises an insulating body with a front end surface, ground terminals, signal terminals and a metal shell, wherein the insulating body is concavely provided with a connecting groove backwards from the front end surface and is used for being inserted with the connecting piece; the ground terminals and the signal terminals are arranged on the insulating body; the ground terminals are partially exposed to the connecting groove to be in contact with the ground conductive pieces; the signal terminals are partially exposed to the connecting groove tobe in contact with the signal conductive pieces; the metal shell covers the insulating body; the metal shell comprises a top plate positioned above the insulating body; the metal shell is provided with first ground parts connected with the top plate; the first ground parts extend forwards from the top plate and are bent backwards to be exposed to the connecting groove to be in contact with the upper shielding part; second ground parts convexly extends downwards from the top plate; third ground parts extend backwards from the top plate; one second ground part and one third ground part are in contact with the same ground terminal; and fixed parts extend backwards from the top plate and are fixed to the insulating body in a matched mode. The high-frequency performance of the electric connector is enhanced.
Description
[0001] 【Technical field】 [0002] The invention relates to an electrical connector, in particular to an electrical connector with improved high-frequency performance. [0003] 【Background technique】 [0004] Nowadays, electrical connectors have been used in various fields of life. With the development of science and technology, the exchange rate of information is getting faster and faster. Therefore, the requirements for electrical connectors are getting higher and higher. Not only electrical connector components are required to be Fast transfer rates are supported and there is also a need to increase the lifespan of electrical connectors. A known electrical connector is used for docking with a pair of mating components. It has an insulating body. A signal terminal is accommodated in the insulating body, and a metal shell is covered outside the insulating body. The metal shell includes a top plate located above the insulating body, and two sides of the top plate each extend do...
