Abstract
A prismatic bar 18 having a square cross-section is provided in a rotation shaft 16 to which plug terminals 14 are fixed, and the rotation shaft 16 is sandwiched between a pair of elastic pieces 17a, 17a of an elastic holder 17, so that the respective elastic pieces 17a, 17a are brought into contact with plane surfaces of the prismatic bar 18 parallel to each other. Therefore, an interval between the two elastic pieces 17a, 17a of the elastic holder 17 is increased when the square bar 18 rotates, and thus, a firm and steady touch of a click can be provided.
Claims13
A power plug, comprising:
- a set of plug terminals;
- a rotation shaft for integrally holding the plug terminals with spaced apart from each other, the rotation shaft having a prismatic bar with a peripheral surface including a plurality of plane surfaces and ridges between the plane surfaces;
- a housing having a bearing for rotatably supporting said rotation shaft;
- and
- a pair of elastic pieces that is positioned to sandwich said rotation shaft and brought into contact with said plurality of plane surfaces of said prismatic bar, the elastic pieces being arranged not to rotate with said rotation shaft and, as the rotation shaft rotates, being elastically deformed to expand by pressure from said ridge of said prismatic bar.

- a housing having a bearing for rotatably supporting said rotation shaft and an accommodation part capable of accommodating said plug terminals, said accommodation part accommodating said plug terminals therein when said rotation shaft is rotated from a projecting position where said plug terminals project from the housing to an accommodated position;
- and
- a pair of elastic pieces that is positioned to sandwich said rotation shaft and brought into contact with said plurality of plane surfaces of said prismatic bar, the elastic pieces being arranged not to rotate with said rotation shaft and, as the rotation shaft rotates, being elastically deformed to expand by pressure from said ridge of said prismatic bar.
