A polygonal contact

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.
