However, such a wire harness grounding method adopted at present has the following problems:
(1) when more than two ring terminals are required to be sleeved on the same ground stud, a worker needs to pay more attention to manually arrange the ring terminals at a specific angle, such as 90 degrees, 120 degrees and the like, to avoid other components in the vehicle. When the number of the ring terminals increases, a worker easily makes a mistake.
(2) Since the ring terminal is manually fitted over the ground stud by a worker, the ring terminal is easily warped, so that interference between a plurality of warped ring terminals occurs when the nut is finally screwed, thereby causing false screwing and poor contact.
