A probe connector includes a barrel, a plunger, an elastic element, at least one first magnet, and at least one second magnet. The barrel defines an enclosure surrounding a chamber. An opening is formed at one end of the barrel. The elastic element is arranged in the chamber of the barrel. The plunger has a basic portion received in the chamber and against one end of the elastic element, and a contact portion extending out of the chamber through the opening. The first magnet is disposed on the enclosure of the barrel. The second magnet is disposed on the basic portion of the plunger. When the plunger is pressed inward, the plunger is leant towards one side with the basic portion against the enclosure because of the second magnet approaching the first magnet to produce a magnetic force interaction therebetween.
