DETAILED DESCRIPTION OF THE INVENTION

[0022] The invention will now be further described with reference to specific embodiments which are further illustrative of the principles of the invention and are not intended to limit the invention in any way, and the same or similar techniques as or to the invention do not exceed the scope of the invention.

[0023] In connection with the drawings As shown in the drawings, a pulling rivet for fasten-connecting a conductive material consists of a rivet and a lantern ring, wherein the rivet comprises a dead head 1.1, a polish rod 1.2, locking grooves 1.3, a pulling groove 1.4 and a short tail 1.5, and the lantern ring comprises a flange 2.1, a deformation area 2.2 and a clamping tooth 2.3; in the present invention, a sharp protrusion 1.6 is arranged on the contact surface between the inner side of the dead head 1.1 and the fasten-coupling piece.

[0024] A height of the protrusion 1.6 provided by the present invention is ⅕˜ 1/12 of the thickness of the dead head 1.1.

[0025] The rivet and the lantern ring may be manufactured from an aluminum alloy material.

[0026] The rivet is applied with solid solution aging treatment, and a cleaning treatment should be carried out on the surface; the lantern ring is applied with softening treatment to be suitable for cold extrusion riveting.

[0027] For the pulling rivet, a conventional installation method is employed, wherein the height H of the protrusion should be ⅕˜ 1/12 of the thickness of the dead head 1.1, so that it pierces the conductive material being connected and does not cause excessive damage to the conductive material to reduce its strength. After the protrusion 1.6 is embedded into the conductive plate, it can prevent the relative sliding between the rivet dead head and the connected piece, thus improving the strength of the fastening connection; meanwhile, it pierces the oxide film or anode oxide film formed by the metal and oxygen on the surface of the conductive material, so that the rivet and the conductive material become a tightly fitted whole, thus improving the conductivity of the entirety.

[0028] The protrusion of the present invention may have a variety of configurations and the following embodiments are merely illustrative of the application thereof.
