Foldable electrical plug connector
View Patent ↗Embodiments of the present invention are directed to an electrical plug connector including a plurality of prongs capable of being coupled to an electrical power source and an outer body having at least one recess. A gearing mechanism is configured to cause retraction of the plurality of prongs. The plurality of prongs is rotatably mounted to the gearing mechanism. At least a portion of each of the plurality of prongs is contained within the at least one recess when the plurality of prongs is retracted.
1. An electrical plug connector, comprising:
a power cable;
a first prong capable of being extended to connect to a first terminal of an electrical power source, the first prong being coupled to a first axle and the first axle being coupled to a first gear;
a second prong capable of being extended to connect to a second terminal of the electrical power source, the second prong being coupled to a second axle and the second axle being coupled to a second gear;
a third prong capable of being extended to connect to a third terminal of the electrical power source, the third prong being coupled to a third axle, the third axle being coupled to a third gear and a fourth gear, the first gear being coupled to the third gear and the second gear being coupled to the fourth gear, so that when one of the first prong, the second prong, or the third prong is retracted, the coupling of the third gear to the first gear, and the fourth gear to the second gear cause others of the first prong, the second prong, and the third prong to be retracted; and
an outer body having at least one recess.
2. The electrical plug connector according to claim 1 , wherein at least one prong of the first prong, the second prong, and the third prong protrudes beyond a surface of the outer body of the electrical plug connector when the first prong, the second prong, and the third prong are retracted.
3. The electrical plug connector according to claim 1 , wherein the first prong, the second prong, and the third prong remain electrically coupled to the power cable when the first prong, the second prong, and the third prong are retracted.
4. The electrical plug connector according to claim 1 , wherein the first prong, the second prong, and the third prong are decoupled from the power cable when the first prong, the second prong, and the third prong are retracted.
5. The electrical plug connector of claim 1 , wherein at least one of the first prong, the second prong, and the third prong lie within the at least one recess when retracted, and at least one of the first prong, the second prong, and the third prong lie proximate the power cable when retracted.
6. The electrical plug connector of claim 1 , further including a first intermediate gear to connect the first gear to the third gear and to allow the first prong to move with the third prong.
7. The electrical plug connector of claim 1 , further including a second intermediate gear to connect the second gear to the fourth gear and to allow the second prong to move with the third prong.
8. The electrical plug connector of claim 1 , wherein the first axle is coupled to the first gear proximate a center point of the first axle and the second axle is coupled to the second gear at a center point of the second axle.
9. An electrical plug connector, comprising:
a power cable;
a first prong capable of being extended to connect to a first terminal of an electrical power source, the first prong being coupled to a first axle and the first axle being coupled to a first gear;
a second prong capable of being extended to connect to a second terminal of the electrical power source the second prong being coupled to a second axle and the second axle being coupled to a second gear;
a third prong capable of being extended to connect to a third terminal of the electrical power source, the third prong being coupled to a third axle, the third axle being coupled to a third gear and a fourth gear, the first gear being coupled to the third gear and the second gear being coupled to the fourth gear, so that when one of the first prong, the second prong, or the third prong is retracted, the coupling of the third gear to the first gear, and the fourth gear to the second gear cause others of the first prong, the second prong, and the third prong to be retracted; and
an outer body having at least one recess, wherein the first prong, the second prong, and the third prong rotate in a same angular direction when one of the first prong, the second prong, or the third prong is retracted.
10. The electrical plug connector of claim 9 , wherein at least one prong of the first prong, the second prong, and the third prong protrudes beyond a surface of the outer body of the electrical plug connector when the first prong, the second prong, and the third prong are retracted.
11. The electrical plug connector of claim 9 , wherein the first prong, the second prong, and the third prong remain electrically coupled to the power cable when the first prong, the second prong, and the third prong are retracted.
12. The electrical plug connector according to claim 9 , wherein the first prong, the second prong, and the third prong are decoupled from the power cable when the first prong, the second prong, and the third prong are retracted.
13. The electrical plug connector according to claim 9 , wherein at least one of the first prong, the second prong, and the third prong lie within the at least one recess when retracted, and at least one of the first prong, the second prong, and the third prong lie proximate the power cable when retracted.
14. The electrical plug connector of claim 9 , further including a first intermediate gear to connect the first gear to the third gear and to allow the first prong to move with the third prong and a second intermediate gear to connect the second gear to the fourth gear and to allow the second prong to move with the third prong.
15. The electrical plug connector of claim 9 , wherein the first axle is coupled to the first gear proximate a center point of the first axle and the second axle is coupled to the second gear proximate a center point of the second axle.
