An electrical connector has a base, and at least one male terminal, at least one female terminal and multiple conductive sheets mounted in the base. The at least one female terminal is configured to be connected with the at least one male terminal of another electrical connector. A connector assembly includes two said electrical connectors. Each one of the electrical connectors is configured to be connected with the other one of the electrical connectors. Since it needs only one mold to manufacture the two electrical connectors for two different purposes, manufacturing cost for the two electrical connectors of the connector assembly can be greatly reduced.
