Abstract

A plug includes a housing, a rotating mechanism, and a pair of pins. The rotating mechanism has a holding member, and a rotating member. The holding member is secured in the housing, and has an elastic arcuate portion having a plurality of recesses. The rotating member is rotatable relative to the holding member, and has a projection mating with each of the recesses of the arcuate portion of the holding member. The pair of pins are secured to the rotating member. The projection of the rotating member is movable along the arcuate portion of the holding member and presses the arcuate portion such that the arcuate portion is elastically deformed until the projection engages one of the recesses of the arcuate portion. When the projection engages one of the recesses, the rotating member and the pair of pins are held in a specific orientation.

First claim

What is claimed is:

1. A rotating mechanism comprising:
a holding member having an elastic arcuate portion having a plurality of recesses; and
a rotating member being rotatable relative to the holding member, and having a projection mating with each of the recesses of the arcuate portion of the holding member;
wherein the projection of the rotating member is movable along the arcuate portion of the holding member and presses the arcuate portion such that the arcuate portion is elastically deformed until the projection engages one of the recesses of the arcuate portion; and
wherein the rotating member is rotable to selectively, by the projection, contact and break contact with the holding member.

2. The rotating mechanism of claim 1 ,
wherein the projection of the rotating member has two intersecting first inclined surfaces; and
wherein each recess of the arcuate portion of the holding member has two second inclined surfaces mating with the first inclined surfaces of the projection of the rotating member.

3. The rotating mechanism of claim 2 , wherein an angle between the first inclined surfaces is an obtuse angle.

4. The rotating mechanism of claim 1 , wherein the rotating member further has two side portions and two shafts respectively extending from the two side portions in a direction perpendicular to the side portions, and the projection is formed on one of the shafts.

5. The rotating mechanism of claim 2 , wherein the rotating member further has two side portions and two shafts respectively extending from the two side portions in a direction perpendicular to the side portions, and the projection is formed on an end of one of the shafts.

6. The rotating mechanism of claim 3 , wherein the rotating member further has two side portions and two shafts respectively extending from the two side portions in a direction perpendicular to the side portions, and the projection is formed on an end of one of the shafts.

7. The rotating mechanism of claim 1 , wherein the holding member further has a rectangular frame having two inner side surfaces, and two ends of the arcuate portion are respectively connected to the two inner side surfaces of the frame.

8. The rotating mechanism of claim 2 , wherein the holding member further has a rectangular frame having two inner side surfaces, and two ends of the arcuate portion are respectively connected to the two inner side surfaces of the frame.

9. The rotating mechanism of claim 3 , wherein the holding member further has a rectangular frame having two inner side surfaces, and two ends of the arcuate portion are respectively connected to the two inner side surfaces of the frame.

10. The rotating mechanism of claim 4 , wherein the holding member further has a rectangular frame having two inner side surfaces, and two ends of the arcuate portion are respectively connected to the two inner side surfaces of the frame.

11. A plug comprising:
a housing;
a rotating mechanism having:
a holding member secured in the housing, and having an elastic arcuate portion having a plurality of recesses; and
a rotating member rotatably mounted on the housing, being rotatable relative to the holding member, and having a projection mating with each the recesses of the arcuate portion of the holding member; and

a pair of pins secured to the rotating member;
wherein the projection of the rotating member is movable along the arcuate portion of the holding member and presses the arcuate portion such that the arcuate portion is elastically deformed until the projection engages one of the recesses of the arcuate portion; and
wherein the rotating member is rotable to selectively, by the projection, contact and break contact with the holding member.

12. The plug of claim 11 ,
wherein the projection of the rotating member has two intersecting first inclined surfaces, and
wherein each recess of the arcuate portion of the holding member has two second inclined surfaces mating with the first inclined surfaces of the projection of the rotating member.

13. The plug of claim 11 , wherein the rotating member further has two side portions and two shafts respectively extending from the two side portions in a direction perpendicular to the side portions, and the projection is formed on one of the shafts.

14. The plug of claim 12 , wherein the rotating member further has two side portions and two shafts respectively extending from the two side portions in a direction perpendicular to the side portions, and the projection is formed on one of the shafts.

15. The plug of claim 13 ,
wherein the housing has a notch for receiving the pair of pins, and the notch has a first wall, and a second wall; and
wherein the shaft of the rotating member without the projection passes through the first wall of the notch of the housing, and the shaft of the rotating member with the projection passes through the second wall of the notch of the housing, such that the rotating member is rotatably mounted on the housing, the projection extends from the second wall to be disposed in the housing, and the holding member is secured to an inner surface of the second wall.

16. The plug of claim 14 ,
wherein the housing has a notch for receiving the pair of pins, and the notch has a first wall, and a second wall; and
wherein the shaft of the rotating member without the projection passes through the first wall of the notch of the housing, and the shaft of the rotating member with the projection passes through the second wall of the notch of the housing, such that the rotating member is rotatably mounted on the housing, the projection extends from the second wall to be disposed in the housing, and the holding member is secured to an inner surface of the second wall.

17. The plug of claim 13 ,
wherein the rotating member further has a connecting portion disposed between the side portions; and
wherein each pin is bent, and has:
a first end extending from the connecting portion of the rotating member; and
a second end extending from the shaft of the rotating member.

18. The plug of claim 14 ,
wherein the rotating member further has a connecting portion disposed between the side portions; and
wherein each pin is bent, and has:
a first end extending from the connecting portion of the rotating member; and
a second end extending from the shaft of the rotating member.

19. The plug of claim 15 ,
wherein the rotating member further has a connecting portion disposed between the side portions; and
wherein each pin is bent, and has:
a first end extending from the connecting portion of the rotating member; and
a second end extending from the shaft of the rotating member.

20. The plug of claim 11 , wherein an angle of the arcuate portion of the holding member is 180 degrees.
