technical field

The utility model relates to a terminal material strip and an electrical connector made by using the terminal material strip, in particular to an HDMI connector.

Background technique

As shown in Figures 1 to 4, the existing connector terminal strip 1' includes a tape carrier 11' and terminals 2' extending from the tape carrier 11', and each terminal 2' includes a docking part 21' and a fixing part 22' , the connecting part 23' and the welding part 24', the fixing part 22' is arranged between the butt joint part 21' and the connecting part 23', the connecting part 23' is arranged between the fixing part 22' and the welding part 24', the The welding part 24' has a straight structure, and the distance between adjacent terminals 2' is relatively small. When the electrical connector made of the terminal strip 1' is used, during automatic welding, the welding part 24' and the tin point The contact surface of the tin spot 3' is small, and the solder point 3' is easy to overflow to the two sides of the welding part 24', and the welding core wire 4' will deviate from the welding part 24', so that the welding coating of the tin point 3' is not enough, and the solder point 3' is not strong. The core wire of the welding wire may be punched away when the injection molding is released, and because the distance between the terminals 2' is too small, it is impossible to weld the wire with a larger core wire, which makes the welding operation very inconvenient, and it is easy to cause false welding and continuous welding, so that the product will be released.
