摘要

PURPOSE: A ball joint is provided to prevent moisture penetration caused by foreign materials or a water leakage in the inside of a ball joint by welding a joint of a socket and a plug after assembling the ball joint, thereby improving the performance of the ball joint and extending a lifetime.;CONSTITUTION: A ball joint comprises a balls stud(110), a ball sheet(120), a socket(130), and a plug(140). The ball stud takes a role of a spheroid joint. The ball sheet covers the ball stud. The socket seats the ball stud and the ball sheet. The plug supports the ball stud so that the ball stud is not separated from the socket by a compressive load. A joint of the ball socket and the plug is joined by welding.;COPYRIGHT KIPO 2012
