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 electric connector comprising a housing having a stop structure and an end cap connected to the housing, wherein at least one conductor connectable to a power supply is arranged in the end cap, characterized in that the conductor comprises a stationary part that is stationary relative to the end cap and a movable part that is movable relative to the end cap, wherein the conductor and the end cap are rotatable relative to the housing from a first position to a second position, wherein the movable part at least partially retracts into the stationary part in the first position, and the 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, wherein after the end cap is rotated to the second position, the stop structure removes obstruction to the movable part such that at least one of the movable parts is movable relative to the stationary part and in electric connection with the power consumption component.

2. The electric connector according to claim 1 , characterized in that the stop structure is configured as a platform with holes, and the movable parts are movable respectively through the holes to be in electric connection with the power consumption component.

3. The electric connector according to claim 2 , characterized in that at least two such conductors are provided, wherein the movable parts of one of the conductors and of the other conductors are connected with the power consumption component by extending different distances from respective stationary parts through the holes.

4. The electric connector according to claim 2 , characterized in that with insertion of the movable part into the hole, the end cap is locked relative to the housing.

5. The electric connector according to claim 2 , characterized in that the platform is formed integrally on an inner wall of the housing.

6. An electric connector comprising a housing having a stop structure and an end cap connected to the housing, wherein at least one conductor connectable to a power supply is arranged in the end cap, characterized in that the conductor comprises a stationary part that is stationary relative to the end cap and a movable part that is movable relative to the end cap, wherein the conductor and the end cap are rotatable relative to the housing from a first position to a second position, wherein the movable part at least partially retracts into the stationary part in the first position, and the 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, further comprising a boss on an inner surface of the end cap, and a slot on an outer surface of the housing, and whereby when the end cap is moved, the boss can be moved out of the slot to allow rotation of the end cap relative to the housing.

7. The electric connector according to claim 6 , characterized in that a torsional spring is provided between the end cap and the housing so as to supply torsional force applied on the end cap.

8. The electric connector according to claim 7 , characterized in that the electric connector further comprises a retainer keeping the torsional spring in the housing, wherein the retainer transfers the torsional force supplied by the torsional spring to the end cap.

9. An electric connector comprising a housing having a stop structure and an end cap connected to the housing, wherein at least one conductor connectable to a power supply is arranged in the end cap, characterized in that the conductor comprises a stationary part that is stationary relative to the end cap and a movable part that is movable relative to the end cap, wherein the conductor and the end cap are rotatable relative to the housing from a first position to a second position, wherein the movable part at least partially retracts into the stationary part in the first position, and the 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, wherein a limiting structure is provided on an outer surface of the housing so as to define a rotating direction of the end cap relative to the housing.

10. An electric connector comprising a housing having a stop structure and an end cap connected to the housing, wherein at least one conductor connectable to a power supply is arranged in the end cap, characterized in that the conductor comprises a stationary part that is stationary relative to the end cap and a movable part that is movable relative to the end cap, wherein the conductor and the end cap are rotatable relative to the housing from a first position to a second position, wherein the movable part at least partially retracts into the stationary part in the first position, and the 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, characterized in that a spring is provided between the stationary part and the movable part.

11. An illuminating device, characterized by comprising at least one electric connector according to claim 10 and a power consumption component arranged in the housing of the electric connector.
