Abstract
Abstract A multilayer, multiconductor or single conductor insulated bus assembly with jacket envelope that will not delaminate or lose capacitance when subjected to high temperatures such as encountered in wave soldering on printed circuit boards or conventional temperature/time soldering cycles. The jacket envelope is formed from an irradiated expanded tube that fits over the conductor bus subassembly and upon application of heat shrinks to a predetermined lesser diameter forming an outer layer about the body of the bus bar subassembly with all connecting terminals extending through openings punched in the jacket.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
82 words
A bus bar assembly that will not delaminate or lose capacitance when subjected to high temperatures comprising a bus bar subassembly and an elastic jacket, said bus bar subassembly includes a plurality of spaced electrical conductors and interleaved insulating layers, each of said conductors having at least one terminal extending beyond the margins of said insulating layers, where said elastic jacket encloses said subassembly with said terminals extending outwardly through openings formed in said jacket and holds said subassembly under elastic compression.
Claim 2
Dependent Claim
82 words
A bus bar assembly that will not delaminate or lose capacitance when subjected to high temperatures comprising a bus bar subassembly and an elastic jacket, said bus bar subassembly includes a plurality of spaced electrical conductors and interleaved insulating layers, each of said conductors having at least one terminal extending beyond the margins of said insulating layers, where said elastic jacket encloses said subassembly with said terminals extending outwardly through openings formed in said jacket and holds said subassembly under elastic compression.
Claim 3
Dependent Claim
43 words
A bus bar assembly as defined in claim 1, wherein said elastic jacket is made of an irradiated expanded modified base polymer tubing and has a recovered cross sectional area smaller than the uncompressed cross sectional area of the body of said subassembly.
Claim 4
Dependent Claim
43 words
A bus bar assembly as defined in claim 1, wherein said terminals project outwardly of said jacket in the same direction and along the length thereof to adapt the bus bar assembly to be mounted on a printed circuit board or the like.
Claim 5
Independent Claim
95 words
A method of forming a bus bar assembly comprising the steps of bonding together a plurality of electrical conductors with interleaved insulating strips with at least one terminal extending from each of said conductors beyond the margin of said insulating strips to form a bus bar subassembly, inserting said subassembly into the open end of an irradiated modified base polymer jacket, and applying heat to said subassembly and jacket to cause said jacket to shrink and conform about the body of said bus bar subassembly with said terminals extending out through perforations in said jacket.
Claim 6
Independent Claim
95 words
A method of forming a bus bar assembly comprising the steps of bonding together a plurality of electrical conductors with interleaved insulating strips with at least one terminal extending from each of said conductors beyond the margin of said insulating strips to form a bus bar subassembly, inserting said subassembly into the open end of an irradiated modified base polymer jacket, and applying heat to said subassembly and jacket to cause said jacket to shrink and conform about the body of said bus bar subassembly with said terminals extending out through perforations in said jacket.
Claim 7
Dependent Claim
72 words
The method of claim 4, wherein said heat applying step comprises punching said terminals through said jacket a sufficIent distance to expose their tips, positioning said subassembly in a soldering position in relation to a printed circuit board or the like, and soldering said terminals, whereby the heat generated by said soldering activates the recovery cycle of said irradiated tubing to cause said jacket to shrink about the body of said subassembly.
