Abstract

An electronic surface mount package provides a one piece construction package (with an open bottom) with one or more terminal pins molded into the package. Each of the pins have a notched post upon which a wire is wound which is from a toroid transformer carried within the package. Each of the posts are notched so their respective wires are separate from one another so as to prevent arcing. The case is opened at the bottom which prevents harm from expansion or cracking.

Claims

1. An electronic surface mount package comprising:

a one piece construction package having a side wall and an open bottom,

a plurality of toroid transformers carried within said package by a soft silicone material, said toroid transformers each having wires wrapped thereon,

a plurality of terminal pins molded within and extending from the bottom of said package, each of the said pins extending through a bottom of said side wall and having a notched post upon which said wires from said transformers are wrapped and soldered thereon, respectively.

2. An electronic surface mount package comprising:

a construction package having a side wall and an open bottom,

a plurality of toroid transformers carried within said package by a soft silicone material, said toroid transformers each having wires wrapped thereon,

a plurality of terminal pins molded within and extending from the bottom of said package, each of said pins extending through a bottom of said side wall and having a notched post upon which said wires from said transformers are wrapped and soldered thereon, respectively.

3. A package as in claim 2 wherein said construction package is one piece.

4. The package of claim 3 wherein said construction package has an open bottom.

5. The package of claim 4 wherein said posts are separated from one another so as to avoid arcing.

6. An electronic surface mount package for mounting on a printed circuit board in an electronic device, said electronic surface mount package comprising:

a one piece construction package having a side wall and an open bottom,

a plurality of toroid transformers carried within said package by a soft silicone material, said toroid transformers each having wires wrapped thereon,

a plurality of terminal pins molded within and extending from the bottom of said package, each of said pins extending through a bottom of said side wall and having a notched post upon which said wires from said transformers are wrapped and soldered thereon, respectively.

7. The package as in claim 6 further including a standoff for maintaining a distance between the bottom of said pins and said printed circuit board.

8. An electronic surface mount package comprising:

a construction package having a side wall and an open bottom,

at least one toroid transformer carried within said package by a soft silicone material, said toroid transformer having a wire wrapped thereon,

at least one terminal pin molded within and extending from the bottom of said package, said pin extending through a bottom of said side wall and having a notched post upon which said wire from said transformer is wrapped and soldered thereon.
