Preferably, described passage of heat is located on the edge of the kink and/or on the inside of the edge of the kink.

It is further preferred that described kink has the side opening for being put into wire rod.

It is further preferred that rectangle of the shape of cross section of the kink for " u "-shaped, " V " shape or a side opening.

It is further preferred that the passage of heat is located at the breach opened wide for side when on the edge of the kink, it is described It is through hole when passage of heat is located on the inside of the edge of the kink.

It is further preferred that on the same kink, described passage of heat includes multiple breach, multiple The shape of cross section of the breach is the combination of same shape or various shapes.

It is further preferred that on the same kink, described passage of heat includes multiple through holes, multiple The shape of cross section of the through hole is the combination of same shape or various shapes.

It is further preferred that on the same kink, described passage of heat includes multiple breach and many The individual through hole, the shape of cross section of multiple breach is the combination of same shape or various shapes, multiple described logical The shape of cross section in hole is the combination of same shape or various shapes.

More preferably, the shape of cross section of multiple breach be selected from " u "-shaped, " V " shape, " W " shape, Y-shaped, rectangle its In one or more of combination.

More preferably, the shape of cross section of multiple through holes is selected from circle, triangle, rhombus, heart, water-drop-shaped, five The combination of the star-shaped one or more of which in angle.

Compared to prior art, transformer framework of the present utility model can be pressed from both sides effectively using the stitch of kink is included The lead-out wire of stringing circle, and passage of heat in kink can accelerate wicking speed and heat transfer, in rope-lay strand Insulating barrier easily melts, and tin layers area coverage is more, and tin welding is firm.
