Abstract
Abstract A CATV package housing electronic circuits designed especially for use in underground cable TV systems is vertically mounted with all connections on the bottom and includes a specialized electrically conductive T-plate that serves as a shield and heat sink positioned between two printed circuit boards to form an interior assembly. The T-plate includes a coaxial connector press fit through the plate to permit RF connection between the boards, with each board containing one or more right-angled coaxial connectors adapted to be inserted into mating connectors in the base of the unit when the circuit board/T-plate assembly is mounted to the base. The subject assembly is designed to be mounted in a small enclosure that may be mounted underground in an underground vault or within an enclosure flush with the ground.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
142 words
An electrical component package comprising: a T-plate including a vertically oriented first member and an orthogonal second member positioned proximate the bottom thereof; a printed circuit board mounted to one side of said vertically oriented first member of said T-plate to produce an interior assembly, said printed circuit board having a right-angled coaxial connector at the bottom thereof extending through the second member of said T-plate; a base having a top surface and at least one mating coaxial connector extending therethrough, with one portion of said mating connector exposed at the top surface of said base and receiving a mating portion of said right-angled connector, said base being secured to said T-plate such that said coaxial connectors mate; and a cover over said interior assembly and said base to provide a vertically oriented package with a coaxial connector extending from said base.
Claim 2
Dependent Claim
142 words
An electrical component package comprising: a T-plate including a vertically oriented first member and an orthogonal second member positioned proximate the bottom thereof; a printed circuit board mounted to one side of said vertically oriented first member of said T-plate to produce an interior assembly, said printed circuit board having a right-angled coaxial connector at the bottom thereof extending through the second member of said T-plate; a base having a top surface and at least one mating coaxial connector extending therethrough, with one portion of said mating connector exposed at the top surface of said base and receiving a mating portion of said right-angled connector, said base being secured to said T-plate such that said coaxial connectors mate; and a cover over said interior assembly and said base to provide a vertically oriented package with a coaxial connector extending from said base.
