Electric connector

The utility model relates to an electric coupler, which is accommodated inside a metal shell, and is used for electrically connecting a PCB with other electric elements, especially electrically connecting a mainboard with a subordinate board usually. The electric coupler comprises an insulating main body and a plurality of modules accommodated in the insulating main body, which is characterized in that: the insulating main body comprises a detachable head and a basal body, the module comprises a basically square insulating frame and a plurality of conducting terminals inserted into the insulating frame and integrated with the insulating frame, the insulating frame comprises two partition ribs to joint two adjacent edges of the insulating frame, the two partition ribs divide the insulating frame into three sections. In addition, each conducting terminal is composed of at least one inserting part and a bending part. The bending part bends the conducting terminal approximately by 90 degrees. The insulating frame divides a plurality of conducting terminals into three groups, of which a central group serves as earth terminal and other two groups as signal terminals. A plurality of electric connectors can be utilized in parallel to improve transmission speed and ensure easy assembling for each electric connector. Besides, the conducting terminal provides better earth screen and improves electrical characteristics.
