Abstract
Abstract An electronic package including a case, circuit board, and elongated electric leads extending from the interior side of said circuit board to the outside of the case and having a snap action interfit with the case automatically locking the parts in attached position upon assembly. The exterior side of the circuit board is coated to provide the exterior side of the package.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
An electronic package comprising: a case having a closed side and a peripheral wall; a circuit board carried by and providing a closure for said case; a plurality of U-shaped spring leads each having one leg connected to and extending interiorly from the interior side of said board and a spring-leg portion thereof extending from said first named leg to a position exterior of said case and in resilient compression against said case wall; and snap means formed by said wall and at least one of said springleg portions in resilient compression against said case wall holding said board in position in relation to the case.
Claim 2
Dependent Claim
106 words
An electronic package comprising: a case having a closed side and a peripheral wall; a circuit board carried by and providing a closure for said case; a plurality of U-shaped spring leads each having one leg connected to and extending interiorly from the interior side of said board and a spring-leg portion thereof extending from said first named leg to a position exterior of said case and in resilient compression against said case wall; and snap means formed by said wall and at least one of said springleg portions in resilient compression against said case wall holding said board in position in relation to the case.
Claim 3
Dependent Claim
78 words
A package as defined in claim 1, said leads being disposed on parallel rows adjacent opposite edges of said board; said wall confronting said edges being formed with a plurality of spaced projections forming interfitting portions to cofunction with said resilient compression of said spring-leg; and at least certain of said spring-legs having a width fitting between said projections and provided with enlarged portions engaging behind the interior ends of said projections locking said board and case together.
Claim 4
Dependent Claim
23 words
A package as defined in claim 2, the exterior ends of at least certain of said projections providing a seat for said board.
Claim 5
Dependent Claim
32 words
An electronic package as defined in claim 1, and a coating of electrical insulation material mounted on the opposite side of said circuit board and defining an exterior side of said package.
Claim 6
Independent Claim
220 words
A method of constructing an electronic package having externally extending leads, a case having a closed side and a peripheral wall, a circuit board dimensioned for fitting within said case with the side edges of said board confronting said peripheRal wall, and electronic components, comprising: mounting of said components on a first side of said board; selecting leads of resilient current conducting material and attaching said leads to said board adjacent its periphery to extend from said first board side; connecting said components and leads at the opposite side of said board in a manner providing a substantially smooth surface at said second side; forming said leads with spring suspended legs extending in a reverse direction to overlie opposite side edges of said board in spaced relation thereto; forming said legs and peripheral wall with interfitting and interlocking portions; coating said second side of said board with an electrical insulation material defining an exterior side of said package; positioning said board with its first side facing interiorally of said case toward the closed side thereof with said legs engaged with said peripheral wall; and moving said board in a direction interiorally of said case resiliently compressing said legs against said peripheral wall and until said portions are moved into registration to effect snap action latching of said board and case.
Claim 7
Independent Claim
220 words
