Abstract

A coaxial connector for mating with a testing pin includes an insulative housing, a fixed contact and a movable contact disposed in the insulative housing. The insulative housing defines a hole for mating with the testing pin and a slot communicating with the hole for accommodating the fixed contact and the movable contact. The fixed contact has a main portion, a projecting portion connected to the main portion. The movable contact positioned to be connected to and disconnected from the fixed contact has a resilient portion and a tail portion connected with the resilient portion. The movable contact provides a protrusion extending downwardly from the resilient portion so that the resilient portion can be prevented from being deflected to the bottom face of the slot to protect the movable contact.
