Specific embodiment

A kind of test connector of the PAD port test for pcb board, including outer conductor 1, outer housing 2, shell spring 3, Inner core 4, dielectric 5, snap ring 8, PIN needle 6, elastomeric element 9 and ground copper 7.

One end of outer conductor 1 is connector female end 11, and the outer wall of connector female end 11 is equipped with screw thread, be can be used for and network The test cable of analyzer connects, and the other end is connector male end 12, and connector male end 12 is for the port PAD with pcb board With contact.

As shown in Figure 1 and Figure 2, the axial centre of outer conductor 1 is equipped with the sky of connection connector female end 11 and connector male end 12 Chamber is equipped with inner core 4, dielectric 5, PIN needle 6 and ground copper 7 in 1 central cavity of outer conductor, and inner core 4 is along connector axis Setting is filled dielectric 5 and is fixed in connector male end, inner core between one end of inner core 4 and the cavity inner wall of outer conductor 1 4 other end extends to connector female end and does not contact with 1 cavity inner wall of the outer conductor at the end, in connector female end 11 4 end center of core offers accommodating chamber 41, and axially disposed PIN needle 6 and elastomeric element 9, PIN needle are equipped in accommodating chamber 41 6 one end is arranged in accommodating chamber 41 by 9 axial elasticity of elastomeric element, and the other end of PIN needle 6 stretches out connector female end 11, The ground copper 7 being connected as one with 1 inner wall of outer conductor is equipped in the cavity of connector female end 11.
