Abstract
Abstract A chassis assembly for electric components having a main chassis provided with a plurality of recesses formed by projecting predetermined parts of the bottom wall outwardly. Each recess is provided with an aperture for receiving the corresponding leg of a sub-chassis carrying electric parts. The legs are inserted into and projected through the apertures and are then welded to the outside of the projected parts of the bottom wall of the main chassis. The alignment of the legs with the apertures is easily achieved and the heating of the projected parts is made in a shorter time to ensure an improved efficiency of the work and good productivity.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
99 words
A chassis assembly for electric components, comprising: a main chassis made of a metallic material and having a plurality of recesses projecting outwardly from the bottom wall thereof, each of said recesses being provided with an aperture formed centrally therein; and a sub-chassis carrying at least one electric part and having means including metallic legs adapted to be inserted into respective ones of said apertures with said legs being projected exteriorly through said apertures of said recesses so that said legs can be soldered to the outside of said main chassis for securing said sub-chassis within said main chassis.
Claim 2
Dependent Claim
99 words
A chassis assembly for electric components, comprising: a main chassis made of a metallic material and having a plurality of recesses projecting outwardly from the bottom wall thereof, each of said recesses being provided with an aperture formed centrally therein; and a sub-chassis carrying at least one electric part and having means including metallic legs adapted to be inserted into respective ones of said apertures with said legs being projected exteriorly through said apertures of said recesses so that said legs can be soldered to the outside of said main chassis for securing said sub-chassis within said main chassis.
Claim 3
Dependent Claim
26 words
A chassis assembly for electric components as claimed in claim 1, wherein said recesses each have an inside diameter greater than that of the respective aperture.
Claim 4
Dependent Claim
20 words
A chassis assembly for electric components as claimed in claim 1, wherein said legs of said sub-chassis have narrowed ends.
Claim 5
Independent Claim
