<p>PLUG-IN TYPE OF POWER SUPPLY A plug-in type of power supply, as an improvement of regular power supply units, specifically it means a separate structure of the transformer apart from the frame shell, structured to have the terminals on the output side of the transformer plugged unto the circuit board so as to achieve in coupling with the power plunger provided on the bottom lid of the frame shell by means of a joint piece made of phosphoric copper, thus sealing up the frame shell, the transformer and the circuit board in the meantime being secured in the frame shell to become a finished power supply unit, the structure of such a power supply unit is designed as such through straight-in plunge-in plugging thereby simplifying assemblage and facilitating replacement of parts during assemblage processing, and Q. C. running as well, thus serving to reduce failure and rejection rates of the products and to aid in automatic mass production by virtue of such piecewise assemblage processings.</p> |
