Abstract

A plug is disclosed that provides for electrically connecting an electronic device, such as a television, to a signal port providing power, ground, audio/video, control and status-reporting signals to and from the device. The signal port is connected to terminals in a receptacle and the plug includes joining structure that can be inserted in or otherwise coupled to the receptacle to mechanically support the plug and the device. The joining structure is provided with retractable contacts to make the electrical connections with the terminals in the receptacle. The retractable contacts avoid damage when the joining structure is inserted into a receptacle that is fouled with debris because the contacts retract on contact with the debris rather than being bent or pushed out of place. The retractable contacts provide hemispherical, partially spherical, elliptical, flat, or other broad surface areas for electrical connection to the terminals, and the terminals may be provided with complementarily shaped and broad surface areas. The complementary shapes and broad surface areas allow for improved electrical connection even if the joining structure and receptacle are not perfectly aligned. The plug may also include an elongate projecting member terminating with first and second ends, with the first end being operatively connected to the joining structure so that the projecting elongate member extends from it and away from the receptacle. A pivot is provided so that the projecting member is articulable in a pivot plane. The projecting member also includes a connector located adjacent its second end for fastening to a housing/support structure for the electronic device.

Claims

1. A connector arrangement for providing a mechanical and an electrical connection, the connector arrangement comprising:

a receptacle having a plurality of electrical terminals;

a joining structure configured to be mechanically connected to the receptacle; and

a plurality of couplers, each coupler including a body removably attached to the joining structure and an electrical contact movably coupled to the body, wherein each coupler body and the joining structure are configured for extraction of each coupler body from the joining structure separate from extraction of each other coupler body,

wherein each of the electrical contacts and a corresponding one of the terminals provide an electrical connection therebetween, when the joining structure and receptacle are mechanically connected, each electrical contact moving from an extended position toward a retracted position as the mechanical and electrical connections are made.

2. The connector arrangement of claim 1 wherein the coupler bodies are generally cylindrical.

3. The connector arrangement of claim 1 wherein the coupler bodies are substantially hollow.

4. The connector arrangement of claim 1 wherein the coupler bodies define longitudinal axes, the body axes being spatially separated from one another.

5. The connector arrangement of claim 1 wherein each coupler includes a piston defining a proximal end and a distal end, wherein the proximal end is movably disposed within the coupler body, and wherein the electrical contact is disposed on the distal end of the piston.

6. The connector arrangement of claim 5 wherein the distal end includes an enlarged, generally hemispherically-shaped head providing the electrical contact.

7. The connector arrangement of claim 1 wherein the electrical contact is generally hemispherical.

8. The connector arrangement of claim 7 wherein the terminal has a convex, generally hemispherical shape.

9. The connector arrangement of claim 1 further comprising a locking mechanism for releasably holding together the joining structure and the receptacle.

10. The connector arrangement of claim 1 wherein one of the joining structure and the receptacle include an alignment track having a delta-shaped opening.
