A type of combined electrical connector is at least made by combining an outer shell component and a tongue component. The tongue component at least consists of a tongue major conductive terminal assembly and a tongue minor conductive terminal assembly. Therefore, after the electrical connector design is completed, customization of the quantity, structure, and electrical connection relationships of the conductive terminals can still be achieved by adjusting the outer shell component and the tongue component to meet the specific requirements and advancements in electronic devices.
