Ground terminal and method of forming it

A method for removing a ground wire from a mount member for recycling, comprising:

• forming a ground terminal with a fixing portion having a bolt opening, a wire-connecting portion for engaging a wire, and a coupling portion coupling the fixing portion and the wire connecting portion, a fracture groove extending across a rear surface of the coupling portion, the fracture groove having a pointed shape, the fracture groove having an apex formed substantially symmetrically on the coupling portion and a projection on the coupling portion at a position proximate to a concave side of the apex of the fracture groove;
• crimping the wire-connecting portion to the wire;
• mounting the fixing portion to the mount member so that the rear surface of the coupling portion faces the mount member;
• and lifting the wire-connecting portion to fracture the coupling portion along the fracture groove.

A ground terminal formed from a piece of metallic material having opposite front and rear surfaces, said ground terminal comprising:

• a substantially annular fixing portion formed with a bolt opening extending between the opposite front and rear surfaces for receiving a bolt for fixing the rear surface to a mount member;
• a coupling portion projecting from an outer periphery of the fixing portion;
• a wire connecting portion extending from the coupling portion and configured for connecting a wire to the front surface;
• and
• a fracture groove formed in the rear surface of the ground terminal and extending completely across the coupling portion, the fracture groove having a substantially pointed shape.

A ground terminal formed from a metallic material and having opposite front and rear surfaces, said terminal comprising:

• a fixing portion formed with a bolt opening extending between the opposite front and rear surfaces for receiving a bolt for fixing the rear surface to a mount member;
• a coupling portion at an outer periphery of the fixing portion;
• a wire connecting portion extending from the coupling portion and having an elongate support extending in a longitudinal direction and at least one crimpable barrel extending transverse to the longitudinal direction for crimping a wire into connection with the wire connecting portion;
• and
• a fracture groove extending completely across the coupling portion and being configured such that at least a major part of said fracture groove is aligned to intersect the longitudinal direction of the wire connecting portion at an acute angle, such that at least one portion of said fracture groove is further from the crimpable barrel than other portions of said fracture groove.
