Abstract

A smart connector for an electrical device comprising: a circuit board including a flat surface for receiving at least one surface-mounted circuit component, a plurality of extending male blades formed in a first end of the circuit board, a plurality of female receptacles formed at a second end of the circuit board opposite the first end, wherein (i) an exterior of each of the extending male blades, (ii) an interior of each of the female receptacles and (iii) a select portion of the flat surface all include electrically conductive circuit traces; and a connector housing having a first end with a plurality of female terminal receptacles for terminating a wiring harness, a body portion for housing the circuit board and a second end, wherein the male blades are each received in a separate one of the plurality of female terminal receptacles and wherein the plurality of female receptacles are located at the second end of the housing for receiving a set of extending male terminals of an electrical device. The smart connector is capable of being sealed to the electrical device to provide protection of the circuit board from an environment outside the housing.

Claims

1. A smart connector for an electrical device comprising:

a circuit board including

a flat surface for receiving at least one surface-mounted circuit component,

a plurality of extending male blades formed in a first end of the circuit board,

a plurality of female receptacles formed at a second end of the circuit board opposite the first end, wherein (i) an exterior of each of the extending male blades, (ii) an interior of each of the female receptacles and (iii) a select portion of the flat surface all include electrically conductive circuit traces

a connector housing having a first end with a plurality of female terminal receptacles for terminating a wiring harness, a body portion for housing the circuit board and a second end, wherein the male blades are each received in a separate one of the plurality of female terminal receptacles and wherein the plurality of female receptacles are located at the second end of the housing for receiving a set of extending male terminals of an electrical device.

2. A smart connector for an electrical device according to claim 1, wherein the connector housing has an interior cavity extending from the second end to the body portion, wherein the circuit board is located within the interior cavity, also comprising:

first and second slots on a pair of opposing walls of the interior cavity, wherein the slots extend from the second end through the body portion;

first and second ribs projecting outwardly from first and second sides of the circuit board and extending substantially from the first end to the second end thereof, wherein the first rib engages the first slot and the second rib engages the second slot to maintain the circuit board located within the housing.

3. A smart connector for an electrical device according to claim 2, also comprising:

first and second ears projecting outwardly from the first and second ribs proximate to the second end of the circuit board;

first and second openings in the second end of the housing, wherein the first opening is in an outside wall of the first slot and the second opening is in an outside wall of the second slot, wherein the first and second ears project through the first and second openings to maintain the circuit board within the housing.

4. A smart connector for an electrical device according to claim 1, wherein the smart connector is sealable to the electrical device, wherein the circuit board and the at least one surface-mounted circuit component are sealed within the connector housing from an environment exterior of the connector housing.

5. A smart connector for an electrical device according to claim 1, wherein the circuit board including the flat surface, the plurality of male blades and the plurality of female receptacles comprises a singularly fabricated one-piece body of thermo-plastic electrically insulative material.

6. A smart connector for an electrical device according to claim 1, wherein the housing including the body portion, the plurality of female terminal receptacles and the second end comprises a singularly fabricated one-piece body of thermo-plastic electrically insulative material.

7. A smart connector for an electrical device according to claim 1, wherein the circuit board comprises:

a body with a platform on one planar side thereof, wherein the platform comprises the flat surface;

a plurality of walls projecting out of the first end of the body extending parallel to the platform wherein the plurality of walls comprises the plurality of extending male blades; and

at the second end of the body, a structure rising in a direction perpendicular to the platform and forming a plurality of cavities aligned parallel to the platform and the male blades, wherein each cavity has an open end for receiving a male terminal of the electrical device, wherein each open end faces a direction away from the male blades and wherein the plurality of cavities comprises the plurality of female receptacles.

8. A smart connector for an electrical device according to claim 1, wherein the circuit board comprises:

a body with a platform on one planar side thereof, wherein the platform comprises the flat surface;

at least one rib extending vertically from the platform opposite the planar side, wherein the rib extends lengthwise substantially from the extending male blades to the female receptacles, wherein one of the extending male blades is integrally formed as an extension out of the one rib.

9. A smart connector for an electrical device according to claim 8, wherein the one rib includes an electrical circuit trace on a top wall and first and second side walls thereof, wherein the one rib provides a path for high power current to and/or from the electrical device.

10. A smart connector for an electrical device comprising:

a housing defining a cavity, wherein a first end of the housing terminates an electrical harness and a second end of the housing defines an opening into the cavity;

a circuit board in the cavity within the housing, the circuit board having male blades extending within the housing to the first end and engaging terminals on the electrical harness, the circuit board also including a plurality of receptacles within the housing at the second end, wherein

the electrical device includes male terminals engaging the receptacles and is in sealing engagement with the housing, sealing the circuit board within the housing.

11. A smart connector for an electrical device according to claim 10, wherein the circuit board includes a platform and a structure rising perpendicularly from the platform, wherein the receptacles are located in the structure.

12. A smart connector for an electrical device according to claim 11, wherein the structure includes a first planar surface facing the electrical device and a second planar surface facing away from the electrical device, wherein the receptacles are defined by the first planar surface and wherein the male terminals of the electrical device are received in the receptacles from the first planar surface side of the structure.

13. A smart connector for an electrical device according to claim 12, wherein the structure defines a rectangular opening in the first planar surface extending into a slot in a direction away from the electrical device, wherein a fuse is received into the slot from the first planar surface side of the structure.

14. A smart connector for an electrical device according to claim 13, wherein the slot is bounded on first and second sides by first and second walls extending from the second planar surface of the structure in a direction away from the electrical device.

15. A smart connector for an electrical device according to claim 14, wherein the first and second walls terminate at an end distal from the second planar surface, extending toward each other to form opposing walls for engaging terminals of the fuse.
