Round needle and motheCONN

Good conductivity: The contact area between the circular pin and the circular hole is large, and the conventional current transmission is stable; However, under high-frequency and high-speed signals, signal reflection may occur due to the presence of small gaps, and shielding measures need to be taken in conjunction.
Moderate lifespan: The standard plug and unplug lifespan usually ranges from tens to hundreds of times, lower than the square hole busbar with four point contact (up to thousands of times). After long-term high-frequency plug and unplug, the contact resistance may gradually increase. ‌‌
