Adaptor assembly for interchangeably mounting hot air solder reflow nozzles to soldering/desoldering apparatus

A hot air solder reflow apparatus for repairing, reworking or producing electronic components and circuit boards of the type having a means for supplying a flow of hot air to an outlet tube and an adaptor assembly for interchangably mounting each of a plurality of different hot air nozzles to the end of said outlet tube;

• wherein said adaptor assembly comprises
• a outer support collar,
• a bezel ring mounted in the support collar, said bezel ring having a plurality of receiving tabs,
• an internal adaptor body which carries the support collar,
• a spring resiliently holding the support collar in an axial direction relative to the internal body;
• and
• wherein each of the nozzles is part of a respective nozzle assembly having a mounting plate with mounting tabs;
• wherein the mounting tabs on the mounting plate of each nozzle assembly is receivable between the receiving tabs of the bezel ring and an end surface of the internal adaptor body in a manner causing compression of the spring and a clamping action of the mounting plate between the end surface of the internal body and said bezel ring.
