Abstract

The invention discloses an electrical connector for electrically connecting a chip module to a circuit board, comprising: a body with a plurality of receiving grooves; a plurality of conductive terminals correspondingly accommodated in the plurality of receiving grooves, The conductive terminal includes: a base; an elastic arm extending upward from the base to abut against the chip module; a material connecting portion extending upward from the base to connect a strip; The extension part is formed by bending and extending from one side of the base part, the extension part is located under the connecting material part and does not interfere with the receiving groove; a conducting part is used to electrically connect the circuit board; Compared with the general conductive terminal, setting the extension part increases the self-capacitance of the conductive terminal, thereby reducing the impedance of the conductive terminal, which is beneficial for the conductive terminal to achieve impedance matching with the chip module and the circuit board, To improve the high-frequency performance of the electrical connector.

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...
