Coaxial connector

Coaxial connector, the electric connector comprises a plastic body, a conductive terminal fixedly held on the plastic body, a shell arranged outside the plastic body and the conductive terminal, and asupport body arranged between the conductive terminal and the shell in the vertical direction and used for pressing the conductive terminal, one of the conductive terminal and the support body protrudes towards the other to form a convex hull, so that an air gap is formed between the conductive terminal and the support body. The convex hull increases the air gap between the conductive terminal and the support body, reduces the equivalent dielectric constant, reduces the capacitance effect, and improves the impedance, thereby improving the high-frequency performance. 一种同轴连接器，包括塑胶本体、固持于塑胶本体的导电端子、设置于所述塑胶本体与导电端子外的外壳及在上下方向设置于所述导电端子与所述外壳之间的以压制导电端子的支撑本体，所述导电端子与所述支撑本体中之一者向另一者突伸形成凸包以使所述导电端子与所述支撑本体之间形成空气间隔。所述凸包增加了导电端子与支撑本体之间的空气间隔，降低等效介电常数，减少电容效应，提高阻抗，从而改善高频性能。
