Abstract

A rotatable plug with an arcing resistant mechanism is disclosed which includes an upper cover, a lower cover mating with the upper cover to form a holding space, a mount placed in the holding space, a rotatable rack placed on the mount, a pair of conductive terminals fixed on the lower cover and a pair of connecting slices. The rotatable rack includes a pivot and a pair of prongs, wherein the prongs are fixed on the both ends of the pivot respectively. Each connecting slice connects the corresponding prong of the rotatable rack with the corresponding conductive terminal. Therefore a circuit exists between the prongs and the conductive terminals, so that the rotatable plug with an arcing resistant mechanism can suppress the arcing that is produced between the prongs and the conductive terminals. Thus the rotatable plug with an arcing resistant mechanism is used safely and has a long lifetime.

Dependent claims

A rotatable plug with an arcing resistant mechanism comprising:

an upper cover which defines a pair of slots in parallel on the top surface thereof;
a lower cover which mates with the upper cover to form a holding space;
a mount placed on the lower cover and held in the holding space;
a pair of conductive terminals disposed on the lower cover, each of which has an engagement portion and a contact portion extending from the engagement portion, wherein the engagement portion is fastened on the lower cover;
a rotatable rack supported by the mount and including a pivot and a pair of prongs, which rotates around the axis of the pivot between vertical position and parallel position with respect to the slots to make the prongs extending out of the slots or be held in the slots;
and
a pair of connecting slices, each of which has a transferring portion, a conductive portion, and a connecting portion, wherein the conductive portion and the connecting portion are bent and extended from both ends of the transferring portion respectively, the conductive portion electrically connects with the corresponding prong, and the connecting portion electrically contacts with the contact portion of the corresponding conductive terminal.
