ABSTRACT:
A power-pack assembly including a bobbin, at least primary and secondary windings wound on the bobbin and a core carried by the bobbin. Solderless connection devices are secured to the bobbin and electrically connected to the windings. The solderless connection devices include clips which engage input and output terminals to make an electrical and mechanical connection therewith. In a preferred embodiment, the terminals are carried by a terminal block which provides a single step plug-in connection between the connection devices and the terminals. A core-grounding system is also disclosed which includes a core-grounding terminal, a spring for electrically contacting the core and a clip secured to the bobbin for engaging the core-grounding terminal and maintaining it in electrical contact with the spring. The core-grounding terminal may be carried by the terminal block for plug-in connection to its clip during the single step plug-in connection of the solderless connection devices and the input and output terminals.
