Problems solved by technology
[0003] The USB interface also has the function of transmitting power, such as charging mobile phones and MP3s. However, the thickness of each conductive terminal of the USB 2.0 electrical connector designed by the industry manufacturers is the same, so that the overall resistance of the conductive terminal is relatively high, resulting in the electrical connector. When the power is transmitted, the heat generated around the conductive terminals is high, which seriously affects the stability of the power transmission of the electrical connector, and causes plastic deformation around the conductive terminals, shortening the service life of the electrical connector

An electrical connector comprises an insulating body and a first terminal group accommodated in the insulating body; the insulating body comprises a base portion and a tongue plate extending forwards from the base portion; the first terminal group is provided with contact portions and welding portions which are arranged on the tongue plate; the first terminal group comprises a first grounding terminal, a power supply terminal and one pair of first differential signal terminals between the first grounding terminal and the power supply terminal; and the thickness of the first grounding terminal or the power supply terminal at the thickness direction of the tongue plate is larger than the thicknesses of other conductive terminals in the first terminal group. With the above structure adopted, the resistance of the first terminal group can be decreased, and therefore, heat emission quantity of the conductive terminals can be decreased, and the stability of power source transmission of the electric connector can be ensured, and the electric connector can transmit large current, and at the same time, the insulating body can be protected from being damaged by large quantity of heat, and the service life of the electric connector can be prolonged.
Description
technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector with power terminals. Background technique [0002] As a standard input / output interface, a universal serial bus (Universal Serial BUS, USB for short) interface has been widely used in the design of many electronic devices. In 1994, Intel (Intel), NEC (Japan Electric Corporation), Compaq (Compaq), DEC (Digital Equipment Corporation of America), IBM (International Business Machines Corporation), Microsoft (Microsoft), Northern Telecom (Northern Telecom Corporation) ) and other world-renowned computer and communication companies jointly established the USB Association (USB-IF), initially establishing the USB specification. So far, the USB Association has released versions 1.0, 1.1, 2.0, and 3.0. The above-mentioned USB 1.0, 1.1, and 2.0 versions support the following three signal transmission rates respectively: (1), the low-speed mode transmission rate is 1.5 meg...
