The inserted terminal of each this first conducting terminal and second conducting terminal and Z-shaped pin be directly punch forming between the both side edges of this metal material belt earlier, make the both sides of its shear surface position at this first conducting terminal and second conducting terminal, and make the upwards bending of this inserted terminal through first knuckle, make it vertically forward through second knuckle again, shear surface being turned the position, and make this Z-shaped pin downward in both sides up and down.

Further, the integrated metalwork of small-sized quick peripheral element interconnection provided by the utility model (Mini PCI Express) slot, wherein the sheet metal correspondence of these two L types is attached on this circuit board.

In addition, the integrated metalwork of small-sized quick peripheral element interconnection provided by the utility model (Mini PCI Express) slot wherein on the both side edges of this metal material belt, is arranged with the circular hole that majority is used for the precompressed positioning function continuously.

By last structure as can be known, first and second conducting terminal of the present utility model is arranged on the metal material belt all simultaneously, and through the secondary bending and moulding, this will make the metal that is consumed in the metal material belt partly greatly reduce, by the direct extrusion molding of insulation shell, more the manufacturing cost of the whole slot that can make greatly descends simultaneously.

According to structure of the present utility model, the Z-shaped pin of conducting terminal bends upwards after lying in drawing again, make this Z-shaped pin downward, thereby preferable structural strength must be arranged to prevent strain, make Z-shaped pin get accurately and be connected on the contact of circuit board, to avoid producing the situation of loose contact with SMT.

Further, extend from the left side and the right side of the housing that insulate respectively the bottom surface of the sheet metal of two L types of the present utility model, can correspondence be attached on the circuit board, provides support.

In addition, on the both side edges of metal material belt, be arranged with the circular hole that majority is used for the precompressed positioning function continuously in the utility model, make the insulation shell of extrusion molding can be accurately the position on the integrated metalwork of the utility model.

Below, design feature of the present utility model will be described in detail according to embodiment shown in the drawings and use effect.
