Patent attributes
An electrical connector includes a terminal module, which includes an insulating block and multiple first terminals retained at the insulating block. Each first terminal has a first contact portion exposed from a bottom surface of the insulating block. A top surface or the bottom surface of the insulating block is concavely provided with at least one groove, each of the at least one groove located between two adjacent first terminals. The groove runs forward through a front end surface of the insulating block and extends backward beyond a rear end of the first contact portion. A second terminal is located on the insulating block. The second terminal has a second contact portion, which is exposed from the top surface of the insulating block. An insulating body is formed outside the terminal module and the second terminal by injection-molding.
