Problems solved by technology

[0003] However, such a design produces a good shielding effect on the conductive terminal part accommodated in the second insulator, but cannot play a good shielding effect on the conductive terminal part in the first insulating body and the third insulating body, which will cause Noise and crosstalk interference between signals can not achieve the effect of electromagnetic shielding stably. With the development of society, electrical connectors with better shielding performance have become the needs of the times.

Abstract

The invention discloses an electrical connector, comprising: a body, wherein the body comprises a plastic module and two substrates, the plastic module is located between the two substrates, the substrates are provided with at least one first grounding terminal hole, a metal layer is disposed in the first grounding terminal hole, the plastic module is provided with a receiving slot corresponding to the first grounding terminal hole, at least one first grounding terminal is received in the first grounding terminal hole and the receiving slot, the body is further provided with at least one second grounding terminal hole that receives at least one second grounding terminal, and the substrates are provided with at least one grounding layer that is connected to the metal layer and exposed to the first grounding terminal hole. Adding the second grounding terminal to the body effectively enhances the shielding effect on interference signals, and the composite structure of the two substrates sandwiching the plastic module provides a good shielding effect on the conductive terminals received therein.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector which connects a chip module and a circuit board and has good high-frequency transmission performance. Background technique [0002] The Chinese invention patent with the notification number CN102270784 discloses a connector, which includes: first, second, and third insulators arranged in sequence up and down, which are respectively provided with a number of first, second, and third insulators corresponding to each other. Three through holes and a plurality of conductive terminals, the conductive terminals include multiple signal terminals and multiple ground terminals. The second insulator is an insulating layer in the printed circuit board. At least one horizontal surface of the second insulator is provided with a second metal plating layer, and the inner wall of the second through hole for accommodating the ground terminal is provided with a first electrical c...
