Definitions
- the present invention is directed towards a electrical contact assembly for a control stalk of an automobile having a contact that moves both vertically and laterally (horizontally) to engage and sweep across the contact of a corresponding printed circuit board or insert molded substrate.
- Switches and levers of various types are well known in the automobile art. Typically, these switches or levers have an actuation device that moves the contact element of a first device into engagement with the contact element of a second device.
- These types of switch assemblies can be the butting type where the electrical contact is pushed linearly into engagement with its corresponding contact, or the sliding or rotating dial type, where the electrical contact is moved along the plane of the corresponding contact from an "off position to an "on” position.
- the contacts of the two devices repeatedly engage each other at the same location, where a thin film, of non-conductive material can build up over time to prevent a secure electrical connection.
- a contact assembly having a contact that travels vertically onto and off of a corresponding contact pad while moving laterally across the same contact pad to provide a self -cleaning mechanism to prevent unwanted film build up on the contact surfaces.
- Such a contact assembly would not require a precious metal portion to prevent contamination.
- the contact switch assembly of the present invention combines the features of the butting type switch and the dial type switch by moving both vertically and laterally to engage a PCB.
- the contact assembly includes a rotating housing and a stalk having a downwardly extending contact arm with contacts thereon.
- the stalk is positioned within the housing and extends out therefrom to engage an inclined surface.
- the stalk moves along the inclined surface so that the contacts engage a printed circuit board (PCB) and slidably travel across its surface.
- PCB printed circuit board
- the present invention provides a contact assembly that moves in both the vertical and lateral direction, providing a self -cleaning mechanism by the movement of the contacts in the lateral direction. Furthermore, the present invention provides a contact assembly having fewer parts, thereby making it easier to assembly and lowering its cost. Also, the fewer number of parts reduces the number of parts that are susceptible to wear and fatigue, increasing the reliability of the contact assembly.
- FIG. 1 shows a side view of a contact assembly of the present invention upon engagement with a PCB
- FIG. 2 shows a side view of the contact assembly of the present invention as it moves laterally across the PCB
- FIG. 3 shows the interior of a housing for the contact assembly
- FIG. 4 shows an exploded view of the contact assembly of the present invention to be incorporated into a steering wheel.
- FIG. 5 shows the contact assembly of FIG. 4
- FIG. 6 shows the contact assembly of FIG. 4 incorporated into the steering wheel
- FIG. 7 shows a side view of the contact assembly of FIG. 4.
- FIGS. 1-3 show side views of the contact assembly 10 of the present invention at various stages of operation.
- FIG. 1 shows the contact assembly 10 upon initial contact with a printed circuit board (PCB) or insert molded substrate 12
- FIG. 2 shows the movement of the contact assembly 10 across the PCB 12
- FIG. 3 shows the contact assembly 10 prior to contact with the PCB 12.
- the contact assembly 10 comprises a housing 14 and a stalk 16 located therein.
- the stalk 16 is a reciprocating arm located within the housing 14 that includes a hollow shaft portion 17, an integrally formed forwardly extending tip portion 18 at one end of the shaft portion 17, and a downwardly extending contact arm 20 projecting from the shaft portion 17.
- Fig. 3 shows the interior of the housing 14 and the stalk 16.
- the housing 14 has a slot 15 along its bottom surface to allow the stalk 16 to move laterally with the contact arm 20 extending through the bottom of the housing 14.
- the slot 15 is shown in FIG. 5, and is further described later in relation to FIG. 5.
- the interior of the shaft portion 17 is hollow and holds a resilient spring 24 which abuts an interior surface of the tip portion 18 to urge the stalk 16 forward.
- the tip portion 18 contacts a inclined surface 22 which forces the stalk 16 to move laterally, inward into the housing 14, as the contact assembly 10 is rotated counterclockwise.
- the contact arm 20 of the stalk 16 extends below the tip portion 18 and includes one or more contacts 24 that extend downwardly from the contact arm 20.
- the contacts 24 move downwardly into contact with the PCB 12 at a first location.
- the stalk 16 moves laterally further into the housing 14, thereby moving the contacts 24 across the surface of the PCB 12 to a second position.
- the distance between the first position and second position is referenced by X.
- FIGS. 4-7 show a preferred embodiment of the invention where the contact assembly 10 is incorporated into a steering wheel assembly of a vehicle. The contact assembly 10 shown in Figs.
- FIG. 4-7 is essentially identical in structure and operation to the contact assembly described above.
- FIG. 4 shows a housing bracket 40 which hold two contact assemblies 10.
- the contact assembly 10 is incorporated into a gear upshift lever 42 and downshift lever 44 on a steering wheel, so that actuating the lever 42 on the right, shifts the vehicle gear up, and actuating the lever 44 on the left shifts the vehicle gear down.
- the gear shift levers and contact assemblies are mirror images of one another and their structure and operation identical, only the upshift gear 42 will be described.
- FIG. 5 shows the upshift lever 42 attached to the housing.
- the upshift lever 42 includes a pair of bearing assemblies 46, into which a pin (not shown) is inserted, and about which the contact assembly 10 rotates.
- the housing 14 includes a slot 15 along its bottom surface through which the contact arm 20 moves in the lateral direction. Additionally, the bottom surface of the housing 14 includes a projection 48 which serves as a stop in cooperation with a corresponding projection 50 on the control arm 20 to prevent the spring 24 from ejecting the stalk 16 from the housing 14.
- the arm of the upshift lever 42 has a circular boss 52 extending down from it. The boss 52 is positioned within a circular spring 54, as best shown in FIG. 5. The circular spring 54 urges the contact assembly 10 upward so that in the default state of the contact assembly
- FIG. 7 is similar to FIG. 2 and shows the contact assembly in operation, except here, the profile of the inclined surface 56 is more elaborate.
- the inclined surface 56 has a varied slope along its length which controls the magnitude of the lateral movement of the stalk 16.
- the contact assembly 10 can be used in any electrical contact system, including vehicle multi-function stalks and other non- vehicular systems.
- the contact assembly 10 may be used in vehicle multifunction stalks to activate window wipers, headlights, turn signals, and various other vehicle functions.
