Abstract

A latch assembly is provided and has a latch housing containing latch components and is integrally coupled to an electronic control assembly having control electronics for controlling the latch components and sensors and switches external to the latch housing. The control housing includes an exterior wall defining an interior cavity for mounting the control electronics. The control housing provides a mechanical connector with an external connector including a set of double sided connectors for coupling an electrical connector to the control electronics. The double sided connectors have a first portion projecting away from the exterior wall and outside of the interior cavity and associated with the mechanical connector for connecting with an electrical system of the vehicle and a second portion projecting away from the exterior wall and into the interior cavity to connect to the control electronics.

wherein the second portion of the double sided connector includes a plurality of pins being in series with one another and adjacent to one another.

2. The latch assembly of claim 1 further comprising a plurality of conductors passing through the exterior wall and connected to the control electronics, the conductors for coupling one or more electrical latch components of the latch assembly positioned external to the interior cavity.

3. The latch assembly of claim 1, wherein the control electronics are configured to be reprogrammed to implement latch operational control functionality.

4. The latch assembly of claim 1, wherein the double sided connector comprises a plurality of pin header connectors being male.

5. The latch assembly of claim 1, wherein the double sided connector comprises a plurality of header connectors being female.

7. The latch assembly of claim 1, wherein the control electronics include a printed circuit board electrically connected to the second portion of the double sided connector.

8. The latch assembly of claim 2, wherein the conductors are embedded in the exterior wall and follow a tortuous path through the exterior wall between the control electronics and the one or more electrical latch components.

9. The latch assembly of claim 1, wherein the latch housing and the control housing are integrally connected to one another.

10. The latch assembly of claim 1 wherein the first portion of the double sided connector extends in a first direction and the second portion of the double sided connector extends in and terminates in a second direction opposite the first direction.

11. The latch assembly of claim 1 wherein the control electronics include a printed circuit board electrically connected to the second portion of the double sided connector, and wherein the double sided connector extends substantially linearly along its entire length between the first portion and the second portion at the printed circuit board.

12. The latch assembly of claim 1 further comprising a plurality of conductors passing through the exterior wall and connected to the control electronics, the conductors for coupling one or more electrical components external to a latch housing of the latch assembly and positioned externally to the interior cavity.

13. The latch assembly of claim 12, wherein the one or more electrical components are selected from the group consisting of:

a sensor and a switch.

14. The latch assembly of claim 11, wherein the printed circuit board overlies and is positioned adjacent to the exterior wall, and wherein the double sided connector extends perpendicularly to the printed circuit board to the first portion and the second portion.

15. The latch assembly of claim 12, wherein the conductors are optically conductive.

16. The latch assembly of claim 12, wherein the exterior wall is molded and the conductors are self supporting for positioning and holding while the exterior wall is molded.

21. The latch assembly of claim 1 wherein the double sided connector extends linearly along its entire length between the first portion and the second portion.

22. The latch assembly of claim 1, wherein the first portion of the double sided connector includes a plurality of pins being in series with one another and adjacent to one another.

23. The latch assembly of claim 1, wherein the first portion of the double sided connector includes a plurality of rows of pins disposed adjacent to one another to form a cluster of pins.

25. The latch assembly of claim 1, wherein the second portion of the double sided connector includes a plurality of rows of pins disposed adjacent to one another to form a cluster of pins.
