Abstract

A power module positioned a desired distance away from a circuit board is described. The module includes a housing supported above the circuit board. The housing includes a cavity having a mechanism for electrically coupling the housing with a circuit board and a system. Circuitry is disposed within the housing cavity to perform electrical functions and controls for the system.

Claims

1. A power module comprising:

a housing defining a cavity and including a rim peripherally about said cavity, said rim including a surface and a flange extending from said surface, said surface and flange adapted for receiving and positioning a first conduit board including circuitry onto said housing such that said circuitry is positioned within said cavity;

means for supporting said housing in a spaced relationship with respect to a second circuit board, said means or supporting unitarily formed with said housing;

means for electrically coupling the circuitry of the first circuit board in said cavity with the second circuit board or an electrical system, said electrical means having a contact portion extending into said cavity adapted to couple with the circuitry on the first circuit board, a contact portion extending from said housing adapted to be coupled with the second circuit board or the electrical system, and the remainder of the electrical means is concealed within said housing such that a portion of the remainder of the electrical means electrically coupling the first and second circuit board is passed through at least one of said supporting means.

2. The power module according to claim 1 further comprising means for dissipating heat from the circuitry positioned within said housing cavity, said means for dissipating heat mounted on said housing and adapted to be associated with the circuitry.

3. The power module according to claim 1 wherein said means for supporting said housing in a spaced relationship includes a plurality of leg members projecting from said housing, said leg members positioning said housing above the second circuit board such that said housing does not interfere with circuitry on the second circuit board.

4. The power module according to claim 1 wherein said means for electrically coupling circuitry enables coupling of one or more circuits selected from a plurality of different circuits to be positioned in the cavity and electrically coupled with the second circuit board or the system.

5. A power module comprising:

a housing defining a cavity and including a rim peripherally about said cavity having an overall rectangular shape, said rim including a surface and a flange extending from said surface, said surface and flange adapted for receiving and positioning a first circuit board including circuitry onto said housing such that said circuitry is positioned within said cavity;

leg means projecting from said housing for positioning said housing a desired distance away from a second circuit board such that said housing does not interfere with circuitry on the second circuit board;

means for electrically coupling the circuitry of the first circuitry board in said cavity with the second circuit board or an electrical system, said electrical means having a contact portion extending into said cavity adapted to couple with the circuitry on the first circuit board, a contact portion extending from said housing adapted to be coupled with the second circuit board or the electrical system, and the remainder of the electrical means is concealed within said housing such that a portion of the remainder of the electrical means electrically coupling the first and second circuit board is passed through at least one of said leg means.

6. The power module according to claim 5 wherein said desired distance away from the second circuit board is at least 1/8 inch.

7. The power module according to claim 5 further comprising means for dissipating heat from the circuitry positioned within said housing, said means for dissipating heat mounted on said housing and adapted to be associated with the circuitry.

8. The power module according to claim 5 wherein said means for electrically coupling circuitry enables coupling of one or more circuits selected from a plurality of different circuits to be positioned in the cavity and electrically coupled with the second circuit board or system.

9. A power module comprising:

a housing defining a cavity and including a rim peripherally surrounding said cavity and having an overall rectangular shape, said rim including a surface, a flange extending from said surface and one or more posts extending from said surface, said surface and flange adapted for receiving a first circuit board including circuitry onto said housing such that said circuitry is positioned within said cavity, said one or more posts adapted to mate with one or more apertures in said first circuit board to position said first circuit board on said housing;

leg means projecting from said housing for positioning said housing a desired distance away from a second circuit board such that said housing does not interfere with circuitry on the second circuit board;

means for electrically coupling the circuitry of the first circuitry board in said cavity with the second circuit board or an electrical system, said electrical means having a contact portion extending into said cavity adapted to couple with the circuitry on the first circuit board, a contact portion extending from said housing adapted to be coupled with the second circuit board or the electrical system, and the remainder of the electrical means is concealed within said housing such that a portion of the remainder of the electrical means electrically coupling the first and second circuit board is passed through at least one of said leg means.
