An improved high frequency connector including an insulative housing, a shield covering the housing, a first terminal and a second terminal defining a switch and securely contacting with each other in normal position. The housing includes an upper insulating case and a lower insulating case with a central cavity, wherein the contact portion of the first and second terminals are extending inside. The second terminal includes a second fixed portion and a second contact portion that is uniform in width up to the second fixed portion before bending forming. The invention is advantageous in that since the second contact portion of the second terminal is uniform in width up to the end of the second fixed portion before being punched and bent to form a contact area, no abrupt change will incur within that region, and therefore providing consistency of impedance, and thus attaining good signal transmission properties. In addition, by providing, respectively, a convex portion and/or cut-off portion for the first and second terminals to prevent the solder flux that is rising due to surface tension by reflow soldering from reaching the switch area, the invention prevents a disadvantage of poor signal transmission properties due to the increasing contact resistance by flux. |
