Abstract

An electrical connector includes an outer insulating body, a first sub-connector, an identification connector and a terminal module. The outer insulating body includes an accommodating space and a second slot located beside of the accommodating space. The first sub-connector includes a first insulating body and a number of first terminals. The first insulating body includes a first slot. The outer insulating body is sleeved on the first sub-connector with the first insulating body accommodated in the accommodating space. Such arrangement simplifies the mounting of the electrical connector. A method for mounting the electrical connector is also disclosed.
