Electrical connector
View Patent ↗A connector for a light source comprises a first cam having a contact surface that is mounted such that the contact surface is extended and retracted relative to the housing. An electrical contact is provided and positioned to contact an electrical terminal in the socket. A conductor is electrically coupled to the electrical contact where the conductor is connected to a light source. An actuator rotates the cam to the retracted position. The connector may be inserted linearly into the socket and the actuator released to mount the light source in the socket.
1. A connector for a light source having a socket comprising:
a first cam arm supporting a first contact surface and a second cam arm supporting a second contact surface connected to the first cam arm at a hinge for movement relative to the first cam arm such that the first contact surface and the second contact surface may be extended and retracted relative to one another;
an electrical contact mounted on at least one of the first contact surface and the second contact surface positioned to contact an electrical terminal in the socket;
a conductor electrically coupled to the electrical contact, the conductor being connected to a light source.
2. The connector of claim 1 wherein the first cam arm, the second cam arm and the hinge are formed of elastic material.
3. The connector of claim 2 wherein the hinge is a living hinge and the first cam arm and the second cam arm are biased to an extended position by the elastic material.
4. The connector of claim 1 wherein the first cam arm, the second cam arm and the hinge are formed of a single-piece of elastic material.
5. The connector of claim 4 further comprising an actuator for rotating the cam arms, the actuator being formed of the single piece of elastic material with the first cam arm, the second cam arm and the hinge.
6. The connector of claim 1 wherein the first contact surface and the second contact surface define at least a portion of a cylinder.
7. The connector of claim 1 wherein the first cam arm extends 180 degrees from the second cam arm.
8. The connector of claim 1 wherein the first contact surface is formed on a first plate and the second contact surface is formed on a second plate.
9. The connector of claim 8 wherein a first leading end of the first plate and a second leading end of the second plate are angled inwardly.
10. The connector of claim 5 wherein the actuator comprises a first lever arm connected to the first cam arm and a second lever arm connected to the second cam arm.
11. The connector of claim 10 wherein the first lever arm and the second lever arm are movable toward one another to retract the first cam arm and the second cam arm toward one another.
12. The connector of claim 1 wherein the electrical contact is formed as a pad of electrically conductive material.
13. The connector of claim 1 further comprising a second electrical contact positioned to contact a second electrical terminal on the socket.
14. The connector of claim 13 further comprising a biasing mechanism for biasing the second electrical contact toward the second terminal.
15. The connector of claim 13 further comprising a second conductor electrically coupled to the second electrical contact, the second conductor being connected to the light source.
16. The connector of claim 1 wherein the first conductor is connected to the light source by a pigtail.
17. The connector of claim 1 wherein the first conductor is connected to a bulb integrated with the connector.
18. The connector of claim 6 wherein the first contact surface and the second contact surface define substantially an entire cylinder where the first contact surface is separated from the second contact surface by a pair of gaps.
19. A method of mounting a light fixture in a socket comprising:
providing a connector connected to a light fixture, the connector comprising a first cam arm supporting a first contact surface and a second cam arm supporting a second contact surface connected to the first cam arm at a hinge for movement relative to the first cam arm such that the first contact surface and the second contact surface may be moved to an extended position and a retracted position relative to one another, an actuator for rotating the first cam arm and the second cam arm to the retracted position and a biasing mechanism for biasing the first cam arm and the second cam arm to the extended position;
manipulating the actuator to move the first contact surface and the second contact surface to the retracted position;
inserting the connector linearly into the socket; and
releasing the actuator.
20. The method of claim 19 further comprising deforming a cylindrical contact surface to move the first contact surface and the second contact surface to the retracted position.
