Description

The structure of universal adapter

Technical field

The utility model relates to a kind of structure of universal adapter, particularly a kind of grounding pin and power pin grafting for various countries' different size appliance plug also can be according to required power supply saddle and the ground connection saddle of only assembling this group for South Africa big plug grafting use, except that being possessed, adapter has the better function, the stock of power supply saddle and ground connection saddle is reduced, to reduce cost, and mat is in the side conductive plate of vertical angle of this group power supply guide card and the lower conducting plate right side that laterally presss from both sides mouth, each extension is provided with one group of oblique conductive plate, and constitute an oblique folder mouthful, and the set group supply hub position of being somebody's turn to do on the panel with respect to this oblique folder mouth, also be provided with an oblique slot, and then formation can supply Australia, " big plug " that states such as New Zealand use pegged graft and used, and makes the utility model adapter have the effect that can peg graft for the appliance plug of more various countries different size.

Background technology

At present because of the progress of science and technology and then driven the prosperity of industry, and it is a feast for the eyes that each electronic product is come out one after another, and because of the electrical equipment of countries in the world with plug and socket, its kenel is had nothing in common with each other and is of a great variety, this problem already brings people many puzzlements, especially going abroad with people, different the causing of kenel because of plug or socket can't make electrical appliance then be the most tangible example when being in harmony public or tourism, in addition, the export trade manufacturer of some electronic products is as making the manufacturer of DC-AC power supply unit UPS and AVR, for in the product superordinate socket that uses applicable to various countries' plug of all kinds, then often busy is badly battered, and each dealer is for the demand of market various product, and caused great warehousing pressure, but still be difficult to solve the problem that miscellaneous plug like this causes, though the existing at present adapter product that solves because of various countries' different size, but still because of overcoming the partly problem of the appliance plug grafting of special requirement, therefore, also must be according to the difference of desiring to sell to country origin, and installing is fit to the socket that this state's plug uses, and the plug of various countries, except Taiwan, Japan, outside the U.S. and Canada are identical, other national plug is all different, and arrive so far, this problem still has to be solved.

Present existing conventional adapter 8 as shown in figure 14, it mainly comprises an adapter body 82, main members such as panel 81 and pinboard 83, be provided with the space of ccontaining one a group of power supply saddle 84 and a ground connection saddle 85 in these body 82 the place aheads, and this group power supply saddle 84 and ground connection saddle 85 can be inserted by body 82 the place aheads, and panel 81 can be combined in body 82 the place aheads, simultaneously and after making this group power supply saddle 84 and ground connection saddle 85 insert body 82, make its electrical connection face 841,851 are exposed to 821 ones of the openings at body 82 rears, and in each opening 821 place, organize separately and establish a conductive reed 86, and after making pinboard 83 and body 82 combining, make the inner 8321 of grounding pin 832 and

power pin

831,8311 can contact with this conductive reed 86, and then formation is electrically connected (as Figure 15 and shown in Figure 16) with ground connection saddle 85 and power supply saddle 84 formations, but traditional adapter 8 has following shortcoming in fact:

1, the grounding pin of its pinboard and power pin need be organized separately and establish conductive reed and can constitute with ground connection saddle and power supply saddle and be electrically connected, and the kind mode of this indirect conducting will make impedance increase, and make the electrical efficiency reduction.

2, this kind mat conductive reed produces the mode of conduction indirectly, makes conduction bad easy elastic fatigue because of conductive reed, and then the situation of outage takes place.

3, its member is many, assembly program is complicated and difficult, thereby defective products rate height, and cost is increased.

Though 4, it can be pegged graft for multinational appliance plug and use, and the big plug in inapplicable South Africa and Australia, the big plug of New Zealand, therefore, it still has the imperfection part.

Summary of the invention

Main purpose of the present utility model provides a kind of structure of universal adapter, top in this group power supply saddle and ground connection saddle, also assembly one can be for the power pin of the big plug in South Africa and the power supply saddle and the ground connection saddle of grounding pin grafting use respectively, and also set up supply hub and the earth jack that power pin and grounding pin for South Africa big plug insert in the relative position of panel, and then constitute and to use for the big plug grafting in South Africa, and can comply with required this group power supply saddle and the ground connection saddle only assembled, or increase this group power supply saddle or ground connection saddle and increase the function that to peg graft for the big plug in South Africa, except that being possessed, adapter has the better function, the stock of power supply saddle and ground connection saddle is reduced, to reduce cost, and mat is in the side conductive plate of vertical angle of this group power supply guide card and the lower conducting plate right side that laterally presss from both sides mouth, each extension is provided with one group of oblique conductive plate, and constitute an oblique folder mouthful, and the set group supply hub position of being somebody's turn to do on the panel with respect to this oblique folder mouth, also be provided with an oblique slot, and then formation can supply Australia, " big plug " that states such as New Zealand use pegged graft and used, and makes the utility model adapter have the effect that can peg graft for the appliance plug of more various countries different size.
