Abstract

The utility model relates to an electric connector that is used for being electrically connected with an external electronic element, wherein the electronic device includes a first conductance body and a basal body that can be contacted with the external electronic element. The basal body is provided with a hole and an elastic body, wherein the inner wall of the hole is provided with a second conductance body, while the elastic body is provided with a terminal containing hole to contain the first conductance body. When the external electronic element is pressed to be contacted with the first conductance body, the elastic body is forced to be deformed, and the first conductance body is forced to move so as to be contacted with the second conductance body. As the utility model has a good elastic body, thus the first conductance body after being pressed can be contacted with the second conductance body of the basal body without any welding but favorable to the electric connection between the chip modules.
