AI Technical Summary
⚠Technical Problem
Existing terminal contacts suffer from insufficient contact stability, poor anti-rotation capability, and uneven insertion and extraction force, leading to poor contact and shortened service life.
⚗Method used
It adopts a polygonal contact design, with the socket body forming a petal with a axial slot, the inner surface being an arc-shaped convex surface, the pin being a hexahedron with edges matching the slot, and a buffer hole at the end to achieve multi-point contact and anti-rotation.
🎯Benefits of technology
It improves the reliability and stability of contact, reduces contact resistance, extends service life, and reduces fatigue damage.

Abstract
This utility model discloses a polygonal contact element, including a socket body. The socket body is slotted along the axial direction, and the slotted socket includes at least two lobes. The inner surface of each lobe is set as an arc-shaped convex surface. In this application, when the pin is inserted into the hexagonal inner hole, the six sides of the hexagon form multi-point contact with the outer wall of the pin. The slot causes the contact arm to undergo elastic deformation, providing a uniform radial clamping force. The hexagonal structure naturally restricts the rotation of the pin, ensuring contact stability.
