[0002] A spring ejector connector generally includes a needle shaft, a needle tube and a spring. The spring is installed in the cavity of the needle tube. The needle shaft is sleeved in the cavity of the needle tube and contacts the spring. The needle shaft, inner tube and spring are riveted together as a whole. The needle shaft can move vertically up and down under the action of external force and the spring. With the development of society, more and more products require large current transmission and fast charging, and some products even have lightning protection requirements. Therefore, the current resistance of the spring ejector is getting higher and higher. At this time, the probe is only in contact with the inner tube, and the contact area between the two is small. At this time, the contact impedance is large and it cannot adapt to occasions with large currents.

[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a spring ejector pin connector is provided to achieve a more practical purpose. Utility Model Content

The setting of the slide groove can make the conductive spring sheet 6 completely contact with the ejector pin 3, and at the same time, play a limiting role to prevent the ejector pin 3 from popping out of the inner tube 2 under the reaction force of the spring 7.
