Abstract

The present invention relates to an electric connector and an illuminating device comprising this electric connector, wherein the electric connector comprises a housing and an end cap connected to the housing, wherein an conductor which can be connected to a power supply is arranged in the end cap, wherein the conductor comprises a stationary part and a movable part, wherein the conductor is rotatable relative to the housing along with the end cap from a first position to a second position, wherein the movable parts at least partially retract into the stationary part in the first position, and at least one movable part extends out of the stationary part in the second position so as to be in electric connection with a power consumption component arranged in the housing.

First claim

What is claimed is:

1. An electrical connector comprising:
an end cap comprising a surface configured to move translationally and rotationally relative to an illuminating device hosting the electrical connector; and
at least one electrical conductor interfaced with the end cap and configured to be electrically connected with a power supply to energize a power consumption component of the illuminating device;
wherein:
in a first mode of operation of the electrical connector, the at least one electrical conductor is prevented from making electrical connection with the power consumption component; and
in a second mode of operation of the electrical connector, the at least one electrical conductor is permitted to make electrical connection with the power consumption component.

2. The electrical connector of claim 1 , wherein in a first position of the end cap relative to the illuminating device:
translational movement of the end cap with respect to the illuminating device is permitted;
rotational movement of the end cap with respect to the illuminating device is prevented; and
the electrical connector is in the first mode.

3. The electrical connector of claim 2 , wherein prevention of rotational movement of the end cap with respect to the illuminating device is provided, at least in part, by a stop structure not native to the end cap.

4. The electrical connector of claim 3 , wherein the stop structure is native to the illuminating device.

5. The electrical connector of claim 2 , wherein translational movement of the end cap with respect to the illuminating device leads to a reduction in length of the at least one electrical conductor.

6. The electrical connector of claim 2 , wherein in a second position of the end cap relative to the illuminating device:
translational movement of the end cap with respect to the illuminating device is permitted;
rotational movement of the end cap with respect to the illuminating device is permitted; and
the electrical connector is in the first mode.

7. The electrical connector of claim 6 , wherein without first providing sufficient translational movement of the end cap with respect to the illuminating device, rotational movement of the end cap with respect to the illuminating device is prevented.

8. The electrical connector of claim 6 , wherein rotational movement of the end cap with respect to the illuminating device leads to an increase in length of the at least one electrical conductor.

9. The electrical connector of claim 6 , wherein in a third position of the end cap relative to the illuminating device when engaged therewith:
translational movement of the end cap with respect to the illuminating device is prevented;
rotational movement of the end cap with respect to the illuminating device is prevented; and
the electrical connector is in the second mode.

10. The electrical connector of claim 1 , wherein the at least one electrical conductor comprises:
a stationary part; and
a movable part movable relative to the stationary part.

11. The electrical connector of claim 10 , wherein the at least one electrical conductor further comprises a biasing element interfaced with the stationary part and the movable part such that the movable part is at least partially retractable into the stationary part against a restoring force of the biasing element.

12. The electrical connector of claim 10 , wherein the end cap is rotatable relative to the illuminating device from a first position to a second position, and wherein:
before the end cap is rotated to the second position, the movable part is prevented from moving relative to the stationary part, and the electrical connector is in the first mode; and
after the end cap is rotated to the second position, the movable part is permitted to move relative to the stationary part, and the electrical connector is in the second mode.

13. The electrical connector of claim 10 , wherein:
in a first position of the end cap relative to the illuminating device, the movable part is at least partially retracted into the stationary part so as to ensure that the at least one electrical conductor is out of electrical connection with the power consumption component; and
in a second position of the end cap relative to the illuminating device, the movable part at least partially extends out from the stationary part so as to ensure that the at least one electrical conductor is in electrical connection with the power consumption component.

14. The electrical connector of claim 1 , wherein in being interfaced with the end cap, the at least one electrical conductor is fixedly engaged with the end cap such that, in rotating the end cap relative to the illuminating device, the at least one electrical conductor travels in tandem therewith.

15. The electrical connector of claim 1 , wherein in being operatively interfaced with the end cap, the at least one electrical conductor is inserted through the end cap.

16. An illuminating device comprising the electrical connector of claim 1 .

17. The electrical connector of claim 1 , wherein the end cap is configured to receive a stop structure that is at least partially insertable within the end cap and prevents rotational movement of the end cap with respect to the illuminating device.

18. The electrical connector of claim 1 , wherein an interior of the end cap includes a boss feature configured to engage in a sliding manner with a slot on an exterior surface of an end of a housing.

19. The electrical connector of claim 1 , wherein the end cap is configured to move translationally and rotationally relative to an exterior surface of an end of a housing.

20. The electrical connector of claim 1 , wherein the end cap further comprises a stem portion extending from within the end cap and configured to move translationally and rotationally relative to the illuminating device.
