Abstract
Abstract An encapsulated electrical device having an encapsulation tray which includes spout members extending from the sidewalls to facilitate the positioning of the lead wires during encapsulation of a substrate in the tray and also serves as a retaining means to prevent potting material from overflowing the walls of the tray. The spouts have constricting wall surfaces which facilitate a clamping action on the lead wires and slanted locating tabs are provided in the tray for positioning the substrate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
An encapsulated electrical device comprising an electrical device having at least one lead wire secured thereto, a shallow, open, tray-like member having a floor and a surrounding sidewall forming a cavity, said cavity receiving said electrical device therewithin, at least one spout member having opposing sidewalls in open communication with said cavity and extending through said sidewall of said tray-like member, said spout extending outwardly and away from a portion of said sidewall opposite the floor in a tapering manner and being open along the entire distance from said sidewall to the outer extremity of said spout and receiving said lead wire, means disposed between the sidewalls of said spout to retain said wire in said spout, a potting material surrounding said electrical device and said wire in said spout, the surface of said spout including an end portion receiving and retaining sufficient potting material in said spout when said material reaches the upper limits of said tray to encapsulate said wire in said spout.
Claim 2
Dependent Claim
165 words
An encapsulated electrical device comprising an electrical device having at least one lead wire secured thereto, a shallow, open, tray-like member having a floor and a surrounding sidewall forming a cavity, said cavity receiving said electrical device therewithin, at least one spout member having opposing sidewalls in open communication with said cavity and extending through said sidewall of said tray-like member, said spout extending outwardly and away from a portion of said sidewall opposite the floor in a tapering manner and being open along the entire distance from said sidewall to the outer extremity of said spout and receiving said lead wire, means disposed between the sidewalls of said spout to retain said wire in said spout, a potting material surrounding said electrical device and said wire in said spout, the surface of said spout including an end portion receiving and retaining sufficient potting material in said spout when said material reaches the upper limits of said tray to encapsulate said wire in said spout.
Claim 3
Dependent Claim
60 words
The encapsulated electrical device as defined in claim 1 wherein said means disposed in said spout to retain said wire in said spout includes two opposing constricting wall sections disposed substantially transversely in said spout in a symmetrical manner and extending a substantial distance across and along said spout with their narrowest constrictions near the outer limits of said sidewall.
Claim 4
Dependent Claim
30 words
The encapsulated electrical device as defined in claim 1 wherein locating tabs having slanted wall portions extend from the sidewall to the floor and across a portion of said floor.
Claim 5
Dependent Claim
23 words
The encapsulated electrical device as defined in claim 1 wherein projections extend from the floor to position the substrate away from the floor.
Claim 6
Dependent Claim
19 words
The encapsulated electrical device as defined in claim 1 wherein a multiplicity of said spouts extend from said wall.
Claim 7
Dependent Claim
17 words
The encapsulated electrical device as defined in claim 5 wherein said spouts have widths of different dimensions.
Claim 8
Dependent Claim
37 words
The encapsulated electrical device as defined in claim 1 wherein said tray has four sidewalls and a multiplicity of spouts, said tray being of a rectangular configuration with all of said spouts positioned on the same sidewall.
