Problems solved by technology

With the development of technology, the frequency of signal transmission is increasing. The impedance of the known conductive terminal structure is difficult to achieve impedance matching when transmitting high-frequency signals, which will easily lead to high-frequency resonance and generate high-frequency noise, which is difficult to meet the performance of high-frequency signal transmission. need

Abstract

The invention discloses an electric connector which is used for electrically connecting a chip module to a circuit board and comprises a body and a plurality of conductive terminals. The body is provided with a plurality of containing grooves for correspondingly containing the conductive terminals. Each conductive terminal comprises a base, an elastic arm, a connecting portion, an extending portion and a conducting portion, wherein the base extends upwards to form the elastic arm for abutting the chip module, the base extends upwards to form the connecting portion for connecting a strip, one side of the base is bent and extends to form the extending portion which is positioned on the lower portion of the connecting portion and does not interfere in the corresponding containing groove, andthe conducting portion is electrically connected with the circuit board. Compared with general conductive terminals, the conductive terminals have the advantages that the self-containing capacity of the conductive terminals is increased by the aid of the extending portions, so that the impedance of the conductive terminals is reduced and can be matched with that of the chip module and the circuitboard, and the high-frequency performance of the electric connector is improved.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector with a terminal with improved high-frequency performance. Background technique [0002] A known LGA type electrical connector has a plurality of conductive terminals for electrically connecting a chip module to a circuit board. The basic structure of the conductive terminals is: a base, an elastic arm and a conductive part , the base is in the shape of a flat plate, and the spring arm extends upward from the base to contact the chip module; the conductive part extends downward from the base to electrically connect the circuit board through solder. With the development of technology, the frequency of signal transmission is increasing. The impedance of the known conductive terminal structure is difficult to achieve impedance matching when transmitting high-frequency signals, which will easily lead to high-frequency resonance and generate high-frequency noise, which...
