Abstract

A power pack assembly includes a housing extending axially about a longitudinal axis. The power pack assembly also includes a circuit board having a board main portion covered by the housing and having a first board extended segment extending radially away from the longitudinal axis and out of the housing and uncovered by the housing. The power pack assembly further includes at least one logic connector disposed on the first board extended segment of the circuit board.

First claim

Having thus described the invention, it is claimed:

1. A power pack assembly comprising:
a housing extending axially about a longitudinal axis;
a circuit board having a board main portion covered by the housing and having a first board extended segment extending radially away from the longitudinal axis and out of the housing and uncovered by the housing;
a heat sink tray operatively coupled to the housing to enclose the board main portion of the circuit board, wherein the heat sink tray is a component separate and distinct from the housing, and
at least one logic connector disposed on the first board extended segment of the circuit board, wherein the at least one logic connector is directed away from the housing, wherein the circuit board further comprises an adjustable second board extended segment extending radially away from the longitudinal axis and out of the housing and uncovered by the housing, the second board extended segment having a power connector disposed thereon, wherein the logic connector and the power connector are adjustable relative to each other in a circumferential, rotational direction to define a range of relative positioning between the logic connector and the power connector, wherein the range of relative positioning includes 180 degrees of angular separation between the logic connector and the power connector.

2. The power pack assembly of claim 1 , wherein the heat sink tray comprises a tray main portion and a first tray extended segment, the tray main portion corresponding to the board main portion and the first tray extended segment corresponding to the first board extended segment.

3. The power pack assembly of claim 1 , wherein the housing has a cylindrical body.

4. The power pack assembly of claim 1 , wherein the first board extended segment and the second board extended segment are located circumferentially adjacent to each other.

5. The power pack assembly of claim 1 , wherein the first board extended segment and the second board extended segment are circumferentially spaced from each other.

6. An electric power steering (EPS) system comprising:
an EPS housing; and
a power pack assembly comprising:
a housing having a main body extending axially from a plurality of flange portions to an end surface about a longitudinal axis, the housing operatively coupled to the EPS housing with at least one mechanical fastener extending through at least one of the flange portions;
a circuit board having a board main portion, a first board extended segment and a second board extended segment, the board main portion covered by the housing, the first board extended segment extending radially away from the longitudinal axis and out of the housing and uncovered by the housing, and the second board extended segment extending radially away from the longitudinal axis and out of the housing and uncovered by the housing;
at least one logic connector disposed on the first board extended segment of the circuit board; and
at least one power connector disposed on the second board extended segment of the circuit board, wherein the at least one logic connector and the at least one power connector are directed away from the housing, wherein the logic connector and the power connector are adjustable relative to each other in a circumferential, rotational direction to define a range of relative positioning between the logic connector and the power connector, wherein the range of relative positioning includes 180 degrees of angular separation between the logic connector and the power connector.

7. The EPS system of claim 6 , the power pack assembly further comprising a heat sink tray operatively coupled to the housing to enclose the board main portion of the circuit board.

8. The EPS system of claim 7 , wherein the heat sink tray comprises a tray main portion, a first tray extended segment and a second tray extended segment, the tray main portion corresponding to the board main portion, the first tray extended segment corresponding to the first board extended segment, and the second tray extended segment corresponding to the second board extended segment.

9. The EPS system of claim 6 , wherein the housing has a cylindrical body.

10. The EPS system of claim 6 , wherein the first board extended segment and the second board extended segment are located circumferentially adjacent to each other.

11. The EPS system of claim 6 , wherein the first board extended segment and the second board extended segment are circumferentially spaced from each other.
