Abstract

An apparatus provides an electrical interconnection between a stationary fixture and a vehicle. A plug assembly provides a plurality of spaced apart plug electrodes. A standoff holds the plug electrodes in mutually parallel, fixed positions extending horizontally and outwardly therefrom. A base portion is fixed to the vehicle for supporting the standoff. A cover is hingably attached to the base portion such that the cover may be protectively positioned over the standoff and plug electrodes in a first position of the cover. An alternate second position of the cover exposes the standoff and plug electrodes. A socket assembly is adapted for use with the stationary fixture and provides an upper protective plate and a lower protective plate. A plurality of socket electrodes are positioned between the plates. An insulating spacer is included for supporting and separating the socket electrodes. A support is positioned between the fixture and the socket assembly for holding the socket assembly in a preferred position for engaging the plug assembly.

Claims

1. An apparatus for providing an electrical interconnection between a stationary fixture and a vehicle comprising:

a plug assembly providing a plurality of spaced apart plug electrodes, a standoff for holding the plug electrodes in mutually parallel, fixed positions extending horizontally and outwardly from the standoff, a base portion fixed to the vehicle for supporting the standoff, and a cover enclosing an interior space, the cover being hingably attached to the base portion such that the cover may be protectively positioned over the standoff and plug electrodes in a closed position of the cover, and may alternately be positioned to expose the standoff and plug electrodes in an open position of the cover;

a socket assembly adapted for use with the stationary fixture, providing upper and lower, horizontally disposed, parallel, spaced apart, protective plates, a plurality of socket electrodes positioned between the plates, the plates providing general electrical isolation of the socket electrodes from the environment; and

a support means positioned between the fixture and the socket assembly for holding the socket assembly in a preferred position for engaging the plug assembly;

such that the vehicle may be moved to a position whereby the plug assembly engages the socket assembly, each one of the plug electrodes being forced into contact with one of the socket electrodes to establish a plurality of electrically conductive paths between the plug assembly and the socket assembly, the cover being forced by an engagement arm on the socket assembly to move from the closed position to the open position to expose the plug electrodes and as an indication that engagement has taken place between the plug assembly and the socket assembly.

2. The apparatus of claim 1 wherein the socket electrodes extend transverse to the direction of vehicle motion such that the plug assembly can be brought into contact with the socket assembly for electrical interconnection over a range of transverse positions of the vehicle with respect to the fixture.

3. The apparatus of claim 1 further including shock absorbing means for absorbing a force in excess of a coupling force, the coupling force being such as is required for the engagement of the plug assembly in the socket assembly, said shock absorbing means enabling the socket assembly to be moved over a range of positions in the line of motion of the vehicle during coupling of the plug assembly in the socket assembly.

4. The apparatus of claim 1 wherein the socket electrodes each include a curved portion, each of the curved portions providing a wiping surface for improved contact with each of the plug electrodes.

5. The apparatus of claim 1 further including a weather seal of a flexible material, the weather seal being held in position between the upper and the lower protective plates such that the plug electrodes engage the seal prior to engaging the socket electrodes, the seal being pushed to one side by the plug electrodes during the engaging of the plug assembly and the socket assembly.

6. The apparatus of claim 5 wherein the flexible material is foam rubber and further including a sheath of sheet plastic around the foam rubber for providing a wear surface.

7. The apparatus of claim 1 wherein the cover includes indicia, said indicia being positioned so as to be visible by the operator of the vehicle when the cover is positioned in the open position so as to indicate to the operator that engagement of the plug assembly and the socket assembly is complete.

8. The apparatus of claim 1 wherein the base portion includes a pivotal mount so that the base portion may be moved over a range of angular positions to accommodate the level of the socket assembly, the pivotal mount including position urging means for urging the plug assembly toward a preferred position.
