The invention discloses a connection method of silver,
copper and
zinc belt-shaped solder and a special connection device used in the connection method. According to the connection method, firstly, oxides on connection faces, to be connected, of two solder belts are removed; the connection portions of the solder belts are placed between an upper
copper plate and a lower
copper plate after being clamped and overlapped through the upper copper plate and the lower copper plate, and the contact faces of the solder belts are coated with silver solder flux and are placed between an upper pressure column and a lower supporting column; the upper pressure column falls downwards so as to tightly press the connection portions and keeps certain pressure; the upper copper plate and the lower copper plate are heated through an upper conductive
electrode and a lower conductive
electrode, so that the connection portions of the overlapped solder belts are heated and melted, the surfaces of the upper and lower copper plates are wetted through the melted solder, the surfaces of the copper plates are uniformly laid, the connection portions become thinner under pressure of the upper copper plate and the lower copper plate, redundant solder forms flash, the flash is
cut off, the upper copper plate and the lower copper plate are worn off, and then connection is achieved. Materials of connectors of the solder belts are uniform, strength of the materials of the connectors of the solder belts is the same as that of
base metal, and connection requirements in the rolling process of the silver, copper and
zinc belt-shaped solder can be met. Meanwhile, the special connection device for the method is simple in structure and convenient to operate.
