Abstract

Insulating ribs are formed into one or more portions of a housing that encloses circuitry of an electrical device. Components mounted on a board are separated according to whether they are related to a primary side of a power transformer or a secondary side. Primary related components are typically mounted on the primary side of an isolation slot formed into a circuit board and components related to the secondary are mounted on the other side. The insulating ribs are strategically placed to protrude through the slots when circuit board is mounted to the housing portion. Thus, when the housing portion is joined to another housing portion, which also may include insulating ribs strategically placed, the ribs increase the breakdown voltage of the boundary.

Claims (19)

1. A system for providing enhanced boundary voltage withstand capabilities in an electric device, comprising:

a portion of a housing for enclosing electric components;

a circuit board for mounting electric components within the housing, the circuit board defining one or more withstand boundary voltage slots;

insulating ribs coupled to the portion of the housing, the insulating ribs protruding through the withstand boundary voltage slots when the circuit board is mounted to the housing; and

wherein the circuit board defines discontinuities in the withstand boundary voltage slots, and the slots are defined such that rib ends that are next to one another include overlapping angled ends parallel to one another.

2. The system of claim 1 wherein the ribs are formed as part of the portion of the housing.

3. The system of claim 2 wherein the ribs and portion of the housing are molded as a single piece.

4. A system for providing enhanced boundary voltage withstand capabilities in an electric device, comprising:

a circuit board for mounting electric components within the housing, the circuit board defining one or more withstand boundary voltage slots, wherein the slots are defined by the circuit board such that insulating ribs coupled to a portion of a housing protrude through the slots when the circuit board is located by the housing; and

wherein the circuit board defines discontinuities in the withstand boundary voltage slots, and the slots are defined such that rib ends that are next to one another include overlapping angled ends parallel to one another.

5. The system of claim 4 wherein the ribs are formed as part of the portion of the housing.

6. The system of claim 5 wherein the ribs and portion of the housing are molded as a single piece.

7. A process for manufacturing an electric device having enhanced boundary voltage withstand capabilities, comprising:

manufacturing a portion of a housing for enclosing electric components;

manufacturing a circuit board for mounting electric components within the housing such that the circuit board defines one or more withstand boundary voltage slots;

coupling insulating ribs to the portion of the housing in a location such that the insulating ribs protrude through the withstand boundary voltage slots when the circuit board is located by the housing; and

wherein the circuit board defines discontinuities in the withstand boundary voltage slots, and the slots are defined such that rib ends that are next to one another include overlapping angled ends parallel to one another.

8. The process of claim 7 wherein the ribs are manufactured as part of the portion of the housing.

9. The process of claim 8 wherein the ribs and portion of the housing are molded as a single piece.
