Description

Technical Field

[0001] The present invention relates to an electrical connection terminal and an electrical connection device, and in particular to an electrical connection terminal and an electrical connection device for grounding. Background Art

[0002] The current wiring harness grounding method is: first crimping the wire with a ring terminal with an octagonal hole, then manually putting the ring terminal with the octagonal hole on the octagonal protrusion of the stud, wherein the stud is welded to the vehicle body by resistance welding to be grounded, and finally using a nut to press the ring terminal with the octagonal hole between the grounding stud and the nut, thereby achieving wiring harness grounding and fixation.

[0003] However, the current harness grounding method has the following problems:

[0004] (1) When more than two ring terminals need to be put on the same grounding stud, workers need to spend more attention to manually place these ring terminals at specific angles, such as 90 degrees, 120 degrees, etc., to avoid other components in the vehicle. When the number of ring terminals increases, workers are prone to make mistakes.

[0005] (2) Since the ring terminal is manually put on the grounding stud by workers, the ring terminal is prone to warping, resulting in interference between multiple warped ring terminals when the nut is finally screwed, causing false tightening and poor contact.

[0006] (3) Since the grounding stud has a height limit and multiple ring terminals stacked on the same stud are prone to warping, the number of ring terminals placed on a grounding stud is very limited. Usually, two are selected to ensure the grounding effect.

[0007] (4) The grounding studs, nuts and ring terminals are all metal parts. The edges of these metal parts can easily squeeze and cut the surrounding wires, causing the insulation of the surrounding wires to fail, which can easily lead to a short circuit.
