Abstract

A connector for supplying electrical connections to a towed vehicle includes a housing structure that encloses the electrical connections in a stowed position. The electrical connections are thus protected from the environment. The connector is secured to the towing vehicle, and properly positions the electrical connections. When it is desired to attach a towed vehicle to the electrical connector, the electrical connector is easily moved to an access position where access is provided to the electrical connections. The connector preferably includes a moving plate which is secured to a fixed base, and carries the wires between the stowed and access positions. Further, the moving plate preferably includes a locking wedge which snaps onto the moving plate to bias locking fingers to lock the wires into the connector at their appropriate positions.

Claims

1. An electrical connector for a towed vehicle comprising:

a base to be secured to a towing vehicle;

a moving plate fixed to said base;

electrical connections fixed to one of said base and said moving plate, said moving plate being movable relative to said base from a stowed position to an access position, said electrical connections being protected and enclosed by the combination of said moving plate and said base when in said stowed position, and being exposed when in said access position; and

one of said base and said moving plate having walls, abutting surfaces on the other for forming an enclosed chamber in said stowed position to protect and enclose said electrical connection.

2. An electrical connector as recited in claim 1, wherein said electrical connections are fixed for movement with said moving plate, and are enclosed by said fixed base in said stowed position and face outwardly of said base in said access position.

3. An electrical connector as recited in claim 1, wherein said base includes at least one hole to receive an attachment member to secure said base to a vehicle, said hole being centered on an angle which will be at an acute angle relative to the vertical when the fixed base is fixed to a vehicle.

4. An electrical connector as recited in claim 2, wherein said moving plate pivots relative to said base.

5. An electrical connector as recited in claim 4, wherein said base has a front wall extending downwardly, and said moving plate includes a forward connector plate which receives said electrical connections, said forward connector plate being received behind said front wall of said base in said stowed position.

6. An electrical connector as recited in claim 4, wherein a portion of said moving plate extends rearwardly of a pivot connection to said base, and said portion contacting said base in said access position, preventing further pivoting of said moving plate.

7. An electrical connector as recited in claim 1, wherein said electrical connections are fixed for movement with said moving plate, and said electrical connections are attached to wires secured to said moving plate by locking fingers extending into locking spaces on said wires, a wedge plate biasing said locking fingers into said locking spaces.

8. An electrical connector as recited in claim 7, wherein said wedge plate includes a plurality of finger wedges which are positioned between said locking fingers to force said locking fingers away from a relaxed position where they are not received in said locking spaces to an actuated holding position where they are received in said locking spaces, holding said wires within said electrical connector.

9. An electrical connector as recited in claim 7, wherein said wedge plate further includes an ear which is snapped into said base at a position adjacent a rear of said moving plate, wherein said moving plate includes a plurality of wells each adapted to receive a wire, and said ear extending into said wells to hold said wires in their respective wells.

10. An electrical connector as recited in claim 9, wherein said moving plate includes an enclosure having forward and rear walls, said connector plate being formed in said forward wall, and a plurality of holes being formed in said rear wall, with said finger wedges extending through said holes in said rear wall and said wires also extending through respective holes in said rear wall.

11. An electrical connector comprising:

a first housing member including forward and rear walls, and a plurality of wires secured in a connector plate adjacent said forward wall, said rear wall including holes for passage of said wires toward said forward wall, said rear wall also including holes for passage of a finger wedge, said first housing member including a plurality of resilient locking fingers selectively biased into a locking space adjacent said wires and

a wedge plate having a rear portion, said wedge plate further including integral finger wedges extending forwardly from said rear portion, said finger wedges selectively passing through said holes in said rear wall, said rear portion remaining outwardly of said holes in said rear wall, said finger wedges being received in contact with said locking fingers, and biasing said locking fingers into said locking spaces to secure said wires in said connector plate.

12. An electrical connector as recited in claim 11, wherein there are at least two of said finger wedges, each of said finger wedges forcing two locking fingers in opposed directions into locking spaces in respective wires.

13. An electrical connector as recited in claim 11, wherein said wedge plate includes an ear at a rearward position which is snapped into a recess in said first housing member.

14. An electrical connector as recited in claim 13, wherein said first housing member includes a plurality of wells rearwardly of said rear wall, said wires each being received in respective ones of said wells, and said ear from said wedge plate locking into a recess above said wells to secure said wires in their respective wells.

15. An electrical connector for a towed vehicle comprising:

a fixed base adapted to be fixed to a towing vehicle;

a moving plate secured to said base; and

electrical connections fixed to said moving plate, said moving plate being moveable relative to said base from a stowed position to an access position, said electrical connections being protected and enclosed by the combination of said moving plate and said base when in said stowed position, and being exposed when in said access position, said electrical connections being received within a connector plate adjacent a forward end of said moving plate, said moving plate including a rear wall including holes for passage of said wires towards said forward wall, said rear wall also including holes for passage of a plurality of finger wedges, said moving plate including a plurality of resilient locking fingers selectively biased into locking spaces adjacent said wires, and a wedge plate attached to said moving plate, said wedge plate including finger wedges selectively passing through said holes in said rear wall, said finger wedges being received in contact with said locking fingers, and biasing said locking fingers into said locking spaces to secure said wires in said connector plate.

16. An electrical connector as recited in claim 15, wherein there are at least two of said finger wedges, each of said finger wedges forcing two locking fingers in opposed directions into locking spaces and respective wires.

17. An electrical connector as recited in claim 15, wherein said wedge plate includes an ear at a rearward position which is snapped into a recess in said moving plate, said moving plate including a plurality of wells rearwardly of said rear wall, said wires each being received in respective ones of said wells, and said ear from said wedge plate locking into a recess above said wells to secure said wires in their respective wells.

18. An electrical connector as recited in claim 15, wherein said moving plate pivots relative to said fixed base.

19. An electrical connector as recited in claim 18, wherein said fixed base has a forward wall extending downwardly, and said connector plate being received behind said front wall of said fixed base in said stowed position.

20. An electrical connector as recited in claim 18, wherein said moving plate extends rearwardly beyond a pivot connection to said base, and a portion of said moving plate contacting said fixed base in said access position providing a stop against further movement.
