<p>An improved high frequency connector comprises an insulative housing10, a shield 20 covering the housing, a first terminal 30and a second terminal 40 defining a switch and securely contacting with each other in normal position. The housing comprises an upper insulating case11 and a lower insulating case 12 with a central cavity123, wherein the contact portion of the first and second terminals are extending inside .The said second terminal 40 including a second fixed portion 42 and a second contact portion43which is uniform in width up to the second fixed portion 42 before bending forming. The invention is advantageous in that since the said second contact portion43 of the second terminal is uniform in width up to the end of the second fixed portion 42 before being punched and bent to form a contact area, no abrupt change will incur within that region and therefore almost consistency of impedance, and thus attain a good signal transmission properties; In addition, by providing respectively convex portion and/or cut-off portion for the first and second terminals to prevent the solder flux which is rising due to surface tension by reflow soldering from reaching the switch area ,thus preventing a disadvantage of poor signal transmission properties due to the increasing contact resistance by flux.</p> |
