Abstract
Abstract A casing for electrical components, component assemblies or integrated circuits, and particularly for electrical surface-wave filters, is disclosed as well as a method of production therefor where the electrically active element rests on a base strip from which project outgoing connectors through the casing walls. The connectors provide mechanical and electrical connection to printed circuit boards. A thermosetting-plastic trough adheres closely to the underside of the base strip, while the side-wall reels of the trough rest on the borders of the upper surface of the base strip. Over the trough is placed a thermosetting-plastic lid so that the active element is contained in an enclosure. The trough-and-lid assembly is then coatable in thermosetting plastic.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
A casing for electrical components having an electrically active element where the electrically active element rests on a base strip which projects outgoing connectors through walls of the casing, the connectors providing mechanical and electrical connection to a printed circuit board, the casing comprising a thermosetting-plastic trough which adheres closely to the under surface of the base strip, and having side-walls each having a heel which rests on a border of the upper surface of the base strip, and a thermosetting-plastic lid which is positioned over the thermosetting-plastic trough to form an assembly, the electrically active element being contained in an enclosure of the assembly of thermosetting-plastic trough and lid, the assembly including the enclosed electrically active element being coated in thermosetting plastic.
Claim 2
Dependent Claim
123 words
A casing for electrical components having an electrically active element where the electrically active element rests on a base strip which projects outgoing connectors through walls of the casing, the connectors providing mechanical and electrical connection to a printed circuit board, the casing comprising a thermosetting-plastic trough which adheres closely to the under surface of the base strip, and having side-walls each having a heel which rests on a border of the upper surface of the base strip, and a thermosetting-plastic lid which is positioned over the thermosetting-plastic trough to form an assembly, the electrically active element being contained in an enclosure of the assembly of thermosetting-plastic trough and lid, the assembly including the enclosed electrically active element being coated in thermosetting plastic.
Claim 3
Dependent Claim
22 words
A casing according to claim 1, wherein the thermosetting-plastic lid is trough-shaped and is positioned trough side down over the thermosetting-plastic trough.
Claim 4
Dependent Claim
37 words
A casing according to claim 2, wherein the thermosetting-plastic trough-shaped lid rests on the thermosetting plastic trough by means of ridges protruding from the underside of the lid towards a crown of the sidewall of the trough.
Claim 5
Dependent Claim
20 words
Casing according to claim 2, wherein each crown of the side-walls of the trough has ridges for supporting the lid.
Claim 6
Dependent Claim
15 words
Casing according to claim 1, wherein the trough and lid have correspondingly stepped contact surfaces.
Claim 7
Dependent Claim
19 words
Casing according to claim 1, wherein the thermosetting-plastic trough, lid and assembly coating are produced by separate injection moldings.
