Abstract
The utility model relates to a switching device for external power supply. The utility model is characterized in that the utility model comprises a conducting wire, wherein, one end of which is connected with a plug-in connecting component which is connected with the external power supply and the other end is connected with a plug-in connecting component which is connected with an electrical appliance. Owing to the switching device which is arranged between the external power supply and the small-size electrical appliance, only one external power supply can meet various requirements of electric equipment by the arrangement of the utility model of different specifications. The utility model has the advantage of simple structure, low manufacture cost and convenient collection. The utility model can be widely used in the connection of various domestic electric equipment and the external power supply.
Description
The utility model relates to the switching device of a kind of small household appliance and external power supply.
General external direct current power supply all has a lead, connects an output plug in the end of lead, then plug is inserted compact radio cassette recorder, in the input jack of power consumption equipments such as language repeater, razor.Yet because the input jack specification of small household appliance equipment is more, required voltage also is not quite similar, therefore, each power consumption equipment often needs to be equipped with the external power supply of a special use, and this just causes has a lot of external power supplys in the family, but can not exchange use.Although some external power supply has four plugs (cross plug), it still is the jack requirement of unappeasable whole small-sized electrical appliances, such as: the jack of a kind of Sony walkman is arranged, and arbitrary plug of crosshead all can not use.Soft in addition lead makes the life-span of whole external power supply be subjected to very big influence very easily fractureing with rigid power shell junction.
At the problems referred to above, it is lower that the purpose of this utility model provides a kind of price, and convenient storage uses external power supply switching device flexibly.
For achieving the above object, the utility model is taked following design: a kind of external power supply switching device, it is characterized in that: it comprises a lead, and an end of described lead is connected with a plug connector that is connected with external power supply, and the other end of described lead connects a plug connector that is connected with described electrical appliance.
The described plug connector that is connected with described external power supply generally is a parent form plug, and the described plug connector that is connected with described electrical appliance generally is a public type plug.
The described plug connector that is connected with described external power supply also can be a public type plug.
The described plug connector that is connected with described electrical appliance can be a single plug, also can be a cross plug, can also be one to be parallel with the cross plug of a single plug at least.
The utility model is owing to take above design, it has the following advantages: 1, the utility model is owing to be provided with a switching device between external power supply and small-sized electrical appliance, therefore, can only just can satisfy the requirement of the multiple power consumption equipment of identical voltage by being equipped with the utility model of different size with an external power supply.2, the utility model is owing to be provided with a switching device between external power supply and electrical appliance, therefore, do not need subsidiary long lead on the external power supply, only an output plug need be set, or an output plughole is set on the shell of hard, so both be convenient to the harvesting of external power supply, and be difficult for again before the soft or hard material, causing the damage that fractures, thereby prolonged the useful life of external power supply effectively.3, the utility model is because simple in structure, and cost of manufacture is cheap, is convenient to collection, has both made therefore that to buy a plurality of the utility model in the family standby, also can not cause the trouble that takes up room and too much money cost.Especially when adopting the voltage adjustable external power supply, more can fully show superiority of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is second embodiment of the present utility model
Fig. 3 is the external power supply schematic diagram that is used with the utility model
As shown in Figure 1, the utility model comprises that the two ends of a lead 1, lead 1 connect a plug connector 2,3 respectively.Plug connector 2 is a parent form plug, has a φ 2.5mm or φ 3.5mm or the jack of other specifications on it, inserts for the output plug on the external power supply.Plug connector 3 is a public type plug, and it can insert in the input jack of mini electrical equipment.
In the foregoing description, the public type plug of plug connector 3 can be single plug, promptly only uses for a kind of jack of specification power consumption equipment.The public type plug of plug connector 3 also can be a cross plug (as shown in Figure 2), for the jack use of four kinds of different size power consumption equipments.Can also be on the cross plug again parallel connection go out at least one plug 4 (such as the plug of Sony's walkman), use with the power consumption equipment that adapts to more kinds of specifications.
As shown in Figure 3,, can also improve traditional external power supply structure owing to use of the present utility model, such as: a parent form plug connector with jack 6 is set on the rigid shell 5 of external power supply, and does not establish long lead 1 in addition.At this moment, the plug connector 2 that the utility model is connected with external power supply should be a public type plug, in the jack 6 that inserts the parent form plug connector on the external power supply shell 5.
In the various embodiments described above, various public types, parent form plug connector can be purchased off-the-shelf from the market, such as, with the mono headset socket as the parent form plug etc.
Claims (6)
