Summary of the invention

The purpose of this utility model is to provide a kind of plug by the conversion different size to adapt to each power supply adaptor of specification socket from different places.

The technical scheme that its purpose that realizes the utility model adopts is: a kind of Change Plug Type Power Adapter, form by inner housing and the one group of plug that optionally is assembled on the housing that electric component is installed, plug has base and pin, housing is made up of loam cake and bottom, on bottom, has chute, in the chute area surrounded, have and be used for the guide card that is connected with the pin of plug, on the root edge of chute, elastic fastening plate is set, the end of elastic fastening plate has clasp, on the base of plug, has the frid that can snap in chute, be provided with the limit of buckleing that cooperates with elastic fastening plate in the bottom of plug, the slideway of projection is set on the bottom in the chute enclosing region.When plug inserts chute, make this process quite smooth and easy because have slideway.

Release bottom for convenience and the connection between the plug have the projection of pushing on elastic fastening plate, the user by this protrude from the elastic fastening plate plane push projection can be easily by by depressing being connected of elastic fastening plate release elastic fastening plate and button limit.

When the chute that inserts bottom at plug makes guide card and contact in the plug contacts, smooth and easy in order to guarantee this process, design guide card and be the inclined-plane towards a side of chute opening.

Concrete, guide card is fixed on the inboard of bottom, and the film guiding slot that passes on the bottom protrudes from the chute end face, and guide card is positioned on the part of bottom inboard and also has the contact that is connected with inner electric elements.

Have the backstay that protrudes from both installed surfaces on the inner side edge of loam cake and bottom, these backstays can also play reinforcement in loam cake and the fashionable positioning action that plays of bottom mounting cover to the sidepiece of power supply adaptor housing after covering.

The pad pin of a protrusion respectively is set on two jiaos of the opposite side on the one side of the installation plug on the bottom, and the pad pin can be against on the metope, prevents that power supply adaptor and metope over-tilting from influencing the splicing stability of the pin and the socket of plug.

Have a nameplate installation depression last covering, various nameplates can be installed in the above easily.

Establish the groove of allowing that guide card slips in the bottom of plug, establish pin contact in the groove.

The beneficial effects of the utility model are: utilize the chute on the bottom that various plug is slided the insertion bottom, the contact of pin is connected with guide card in the plug, guaranteed the versatility of this power supply adaptor, the slideway that protrudes, reduced the friction of bottom and plug bottom, it is more smooth and easy to make that plug snaps in the process of bottom, and the projection of pushing on elastic fastening plate has made things convenient for being connected of the light release power supply adaptor of user housing and plug.
