Abstract

Abstract In the production of electronic or electrical components encapsulated in a clear plastic the ends of the conductor leads are connected to hollow ferrules or solid blocks of a relatively soft metal which can easily be cut by the tools employed for cutting the surfaces of the plastic. The blocks or ferrules may initially form part of a single die casting, the base of which is cut away in the course of cutting the plastic.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 134 words
Electrical or electronic apparatus comprising a block of clear plastic material, said block having smooth machined surfaces, at least one electrical or electronic component encapsulated in said block, conductor leads connected to said at least one component, said leads being within said block, enlarged metal end portions of at least 2 mm. transverse breadth connected to said conductor leads, said end portions being located at a said block surface and being of soft metal machinable simultaneously and with the same tools as said plastic material, said block and said end portions having been machined such that said surfaces are smooth and said enlarged end portions have smooth faces in a said surface, whereby external electrical lead connections to said at least one component can be readily effected by connection to said enlarged end portions.
Claim 2
Dependent Claim 134 words
Electrical or electronic apparatus comprising a block of clear plastic material, said block having smooth machined surfaces, at least one electrical or electronic component encapsulated in said block, conductor leads connected to said at least one component, said leads being within said block, enlarged metal end portions of at least 2 mm. transverse breadth connected to said conductor leads, said end portions being located at a said block surface and being of soft metal machinable simultaneously and with the same tools as said plastic material, said block and said end portions having been machined such that said surfaces are smooth and said enlarged end portions have smooth faces in a said surface, whereby external electrical lead connections to said at least one component can be readily effected by connection to said enlarged end portions.
