Abstract

The present invention includes a plug assembly and cord set for use with an automobile accessory that is mounted to an automobile body. The plug assembly includes a plug body having a contact surface, electrical contacts coupled to the plug body and projecting from the contact surface, and a protector cap that accommodates the contacts and protects the contacts from the surrounding environment when the protector cap is in its closed position. The protector cap includes a contact cavity and a cap seal surface surrounding the contact cavity at an open end thereof. The protector cap is coupled to the plug body for pivotal movement between an open position and a closed position wherein the electrical contacts are disposed within the contact cavity and the cap seal surface engages the contact surface to seal the contact cavity when the protector cap is in its closed position. The present invention further includes a mounting assembly for connecting the plug to the vehicle body wherein the mounting assembly includes a mounting bracket having an aperture to accommodate the plug body and the plug body includes a coupling tab having a first end integral with the plug body and a second end movable between an engaged position and a retractive position. When the coupling tab is in its engaged position the tab engages a mounting bracket to couple the plug body to the mounting bracket.

Claims

1. A plug assembly for use with an automobile accessory mounted to an automobile body, said plug assembly comprising:

a plug body having a contact surface and a recess face surrounding said contact surface;

electrical contacts coupled to said plug body and projecting from said contact surface; and

a protector cap including a contact cavity extending between a closed end and an open end thereof, said protector cap having an end face located at a first plane at said open end, a cap seal surface located at a second plane surrounding said contact cavity at said open end and a recess surface extending between said end face and said cap seal surface, said protector cap coupled to said plug body for movement between a closed position and an open position, said electrical contacts and said contact surface disposed within said contact cavity, said recess surface of said protector cap surrounding said recess face of said plug body and said cap seal surface engaging said contact surface to seal said contact cavity when said protector cap is in said closed position.

2. The plug assembly of claim 1 wherein said plug further includes a hinge coupled to a first side of said plug body and a first side of said protector cap such that said hinge pivotably connects said protector cap to said plug body.

3. The plug assembly of claim 2 wherein said hinge includes a spring urging said protector cap toward its closed position.

4. The plug assembly of claim 2 wherein said contact cavity includes a main cavity and a secondary cavity communicating with said main cavity, said main cavity accommodating said contacts when said protector cap is in said closed position, said electrical contacts passing through said secondary cavity when said protector cap is moved between its open and closed positions.

5. The plug assembly of claim 4 wherein said contact surface includes a generally rectangular segment extending from said first side of said plug body and a second segment projecting from said generally rectangular segment opposite said first side of said plug body.

6. The plug assembly of claim 5 wherein said main cavity is generally rectangular in cross-section at said open end of said protector cap and extends from said first side of said protector cap, said secondary cavity projecting from said generally rectangular portion of said main cavity opposite said first side of said protector cap, said cap seal surface being continuous about said main and secondary cavities at said open end of said protector cap.

7. The plug assembly of claim 1 further including a mounting assembly adapted to couple the plug body to the automobile body, said mounting assembly including a mounting bracket adapted to be connected to the automobile body and having an aperture, said mounting assembly further including a coupling tab having a first end integral with said plug body and a second end movable between an engaged position wherein said coupling tab engages said mounting bracket to couple said plug body to said mounting bracket and a retracted position wherein said plug body is movable relative to said mounting bracket.

8. The plug assembly of claim 7 wherein said plug body further includes a head integral with a tail, said head defining an engagement face and said contact surface, said tail extending from said engagement face of said head, and wherein said first end of said coupling tab is integral with said tail and said coupling tab extends toward said head.

9. The plug assembly of claim 8 wherein said mounting bracket is retained between said engagement face and said second end of said coupling tab.

10. A cord set for an electrically powered automobile accessory coupled to a vehicle, wherein the cord set includes a cord having a first end electrically connected to the electrically powered automobile accessory, a second end having a plug with male electrical contacts extending from a contact surface of the plug, the cord set further including a mounting mechanism for coupling the plug to the vehicle, wherein the improvement comprises:

a protector cap pivotably coupled to said plug for movement between an open position and a closed position, said protector cap defining a cavity about said male electrical contacts when the cap is in its closed position, said protector cap including an end face located at a first plane, an engagement face located at a second plane and a recess surface extending therebetween, said engagement face engaging said contact surface of said plug when said protector cap is in said closed position to define a seal between said engagement face and said contact surface.

11. The cord set of claim 10 further including a hinge pivotably connecting said cap to a first side of said plug.

12. The cord set of claim 10 wherein the mounting mechanism includes a mounting bracket adapted to be connected to the vehicle and having an aperture, said mounting mechanism further including a coupling tab having a first end integral with the plug and a second end movable between an engaged position wherein said coupling tab engages the mounting bracket to couple the plug to the mounting bracket and a retracted position wherein the plug is movable relative to the mounting bracket.
