Abstract

An electrical connector is used for electrically connecting a chip module to a circuit board, and includes a body for upward supporting the chip module. The body is provided with multiple accommodating holes. Multiple terminals are respectively accommodated in the accommodating holes correspondingly. Each terminal is provided with at least one soldering portion in contact with a solder and being soldered to the circuit board. A first portion and a second portion are formed by extending upward from the at least one soldering portion and are located at two opposite sides of the solder. An elastic arm bends upward and extends from the second portion for abutting the chip module. When the chip module presses the elastic arm downward, the elastic arm abuts the first portion. Therefore, two conductive paths are formed in parallel to each other.

First claim
