Description
The utility model relates to a kind of power supply unit changeover plug, be specially a kind of power supply unit that can corresponding different sockets comes conversion plug on it, can change the multi-functional changeover plug of power supply unit of the plug of different types according to user's needs easily with this.
Because the chance of people's travel abroad or commercial exchange is increasing, be available for users to select the power supply unit (or charger) of different plugs promptly to seem quite important according to different environments for use (different socket pattern), relevant in recent years design is finished by exploitation constantly, some is domestic by external introducing, some is then developed voluntarily by compatriots and finishes, and these products bring the people that go abroad sizable convenience really.
Relevant product is all similar in the circuit collocation, it all is in order to direct voltage is reduced or be equipped with conversion to exchange the electron exchange power circuit of pressing, main discrepancy then is on the structural design that the plug of its various different sizes changes, early stage design can be found the product of multiple different types in travel goods brand shop on the market, but these products only are simple concatenation type design mostly, for example patchplug is general basic can say without any intention, progressive design then as: No. the 85214261st, TaiWan, China patent " travelling with the charger of convertible attaching plug ", No. 85216668 " travelling " with the power supply unit of convertible attaching plug, No. 85218004 " travelling " with the power supply unit of convertible attaching plug, these structures have all adopted revolving design, the pin rotation of plug can be folded to the lower house bottom surface, making things convenient for the user to collect or portable, its true tool convenience and practicality.
Modern structure with aforementioned No. 85216668 TaiWan, China patent is that example explains, its structural arrangements promptly as shown in Figure 5, this changeable type attaching plug 90 is the conductive base pins 94 that are equiped with on a plastic cement body 92 corresponding to socket, and have two protruding 96 in the both sides, rear end of plastic cement body 92, this protruding axle 96 can be installed in the lower house 82 of this power supply unit 80, and this conductive base pin 94 extends back and exposes two contact jaws 98 in the trailing edge of plastic cement body 92, make contact jaw 98 can when attaching plug 90 outwards overturns, contacting after the combination, so that suitable conduction effect to be provided with the kink of two conducting strips 84.
Analyze from structure, desired practicality effect when aforementioned patent can reach its design really, but analyze from security standpoint, aforesaid structural design is only noticed its functional demand and is reckoned without dangerous strick precaution, though aforementioned changeable type attaching plug 90 is filled in the power supply unit 80 by suitable structural group, as long as the design that modular structure is all arranged in pairs or groups and helped breaking away from, in actual use also might be because assembling is certain inadequately, the improper operation of user or other unknown causes and cause the disengaging of attaching plug 90 and power supply unit 80, design according to this attaching plug 90, if itself and power supply unit 80 still are plugged on the socket when breaking away from, then its two contact points that expose 98 promptly become the trap of murther, when the user touches or desire when this attaching plug 90 is pulled up on by socket accidentally, the all danger that might get an electric shock, this obviously is that these structural designs are improved part inadequately.
Be plug in response to the countries in the world different size, though also once seeing has more perfect design, such as: No. the 86200107th, the novel patent of TaiWan, China " easy-operating ten thousand state's plugs ", the defective that this structure does not promptly have said structure easily to allow the user get an electric shock, but it only can provide simple plug translation function, and can't provide the effect of transformation or rectification, necessary collocation transformer or rectifier in addition when the user uses, in operation, still do not want to take the trouble, also show inconvenience on carrying, it obviously can't satisfy user's multiple demand.
Main purpose of the present utility model is to overcome the defective that conventional apparatus easily causes electric shock, provides a kind of allowing combine the multi-functional changeover plug of more firm power supply unit between power supply unit and plug.
For reaching above-mentioned purpose, the utility model provides a kind of power supply unit multi-functional changeover plug, form by a power supply unit and a plug, this power supply unit is to assemble electric component by the housing that loam cake and lower cover constitute, the plug of different size optionally is assembled on the power supply unit, be characterized in: be provided with a chute in the lower cover bottom surface, and be provided with an elastic fastening plate in the chute root edge, in chute, be provided with the elasticity guide card in addition, the plug bottom surface is provided with the slide plate that matches with the lower cover chute, be provided with the limit of buckleing of matching with the lower cover elastic fastening plate at this slide plate edge, be provided with the chase that slips into for lower cover elasticity guide card in the plug bottom surface, in this chase, be provided with the contact that matches with plug base pin, the plug of different size can be selected to be assembled in the chute of power supply unit by slide plate with this, and can hold the button limit by the elastic fastening plate button and fix, simultaneously by the contact turn-on power in elasticity guide card and the chase.
The multi-functional changeover plug of aforesaid power supply unit, wherein, the end of this elastic fastening plate is provided with a button hook, and is respectively equipped with a joint-cutting in the both sides of this elastic fastening plate.
