need for fastening hardware such as screws rivets etc is eliminated as the first and second housing members are brought together the wire terminals 5 guide themselves onto the reliefs 24 of second housing member 11 the bent prongs 26 shown in fig6 and fig7 top view slide onto the interior side of the enclosure wall and prevents the wire terminals from being pulled out of the assembly external prongs 28 shown in fig6 are positioned outside of the enclosure to prevent the wire terminals from being pushed into the enclosure assembly once the assembly is complete the wire terminals are held rigidly in place and can not be repositioned or removed unless the enclosure is reopened fig3 shows the transformer nested inside the enclosure with the bus bar protruding form either side molded gussets 18 on the interior of the first and second housing members 9 11 come in contact with the sides of the transformer bobbin 36 with a snug fit as the first and second housing members are fastened together the gussets 18 confine the transformer 39 s movement inside the enclosure to prevent excessive vibration or movement in the event of an impact force to the enclosure the snap together method of the enclosure assembly makes use of the elastic properties of the thermoplastic material.
