Description

The duplicate supply adapter

Technical field

The utility model relates to a kind of power supply change-over device, relates in particular to a kind of duplicate supply adapter.

Background technology

Electronic electric equipment is various day by day; Indispensable in people's production, life; Its interface type, working power etc. also are that difference is arranged more; Therefore, all kinds of power supply change-over devices that are used for translation interface type and voltage of transformation are important all the more, for example with light a cigarette joint and civil power converted into the adapter that meets USB interface voltage of vehicle power output interface conversion USB interface automobile-used.But present automobile-used joint and the adapter of lighting a cigarette all is the product of absolute construction, has no assembling between the two, uses relation; For the user; Exist volume big, carry shortcoming such as inconvenience, for manufacturer, have the problem that whole manufacturing cost is high, organization of production is loaded down with trivial details.

Summary of the invention

The purpose of the utility model is to provide a kind of duplicate supply adapter, adopt to merge the technological means of adapter and the automobile-used joint that lights a cigarette, with solve the volume that prior art exists big, carry problems such as inconvenience, cost height.

To achieve these goals, the duplicate supply adapter that provides of the utility model comprises automobile-used joint and the adapter of lighting a cigarette; The rearward end of the said automobile-used joint that lights a cigarette and the leading section of the said adapter structure that becomes one, the common output interface of said automobile-used light a cigarette joint and said adapter is positioned at the rear end face of said adapter.

According to a kind of preferred implementation of above-mentioned duplicate supply adapter, wherein, the outside, the housing of the said automobile-used joint that lights a cigarette upper end is provided with two annular slots that are used to increase stability.

According to a kind of preferred implementation of above-mentioned duplicate supply adapter, wherein, the plug of said adapter is a rotary connector, and the rotary connector of said adapter points to the rear end face of said adapter when being in contraction state; The transformer of said adapter is positioned at the inner leading portion of said adapter.

Therefore the utility model has merged automobile-used voltage jointer and adapter, has at least two types input interface, and a common output interface.In actual application, even run into bigger vibrations, an end of the automobile-used joint that lights a cigarette also can keep good stable property, runs into than the big bang difficult drop-off.One end of adapter is through being integrated in plug its housing, can simplified structure, and reduced volume reduces cost.Therefore, after the common advantage that merges adapter and the automobile-used joint that lights a cigarette,, the utility model can be obtained beneficial effects such as volume is little, easy to carry, good stability, difficult drop-off, application is convenient, cost is low.

Description of drawings

Fig. 1 is the perspective view of the utility model preferred embodiment;

Fig. 2 is vertical cross-sectional schematic of the utility model preferred embodiment.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.

Fig. 1 and Fig. 2 schematically show the surface structure and the internal structure of the utility model preferred embodiment; As shown in the figure; This preferred embodiment comprises automobile-used joint 1 and the adapter 2 of lighting a cigarette; The anodal copper cap 12 of the automobile-used joint 1 that lights a cigarette is positioned at the leading section of the automobile-used joint 1 that lights a cigarette, and negative pole jump ring 11 is exposed to the housing both sides of the automobile-used joint 1 that lights a cigarette, and two annular slots (in figure unmarked) adjacent with anodal copper cap can increase the stability of the automobile-used joint 1 that lights a cigarette; Prevent landing, negative pole jump ring 11 also has the effect that increases stability certainly.Negative pole jump ring 11 is the gear shape, has two plastics screens.The

plug

22,24 of adapter 2 is a revolvable plug, when plug leaves unused, can screw in the storage tank 23.The transformer 26 of adapter 2 is positioned at the leading portion of adapter 2 inside.The rearward end of the automobile-used joint 1 that lights a cigarette and the leading section of adapter 2 structure that becomes one, the automobile-used common output interface 25 that lights a cigarette joint 1 and adapter 2 is positioned at the rear end face of adapter 2, and common output interface 25 is preferably USB interface.It is thus clear that this preferred embodiment not only has a plurality of input interfaces of the two, and dwindled the overall volume of the two after integrated automobile-used light a cigarette joint 1 and adapter 2, all right many usefulness of article have significantly increased user convenience property.

In order further to increase the range of application of this preferred embodiment; On the plug rotating shaft of adapter 2 two types of plugs can be set, for example double-legged flat plug 24 or double-legged circular plug 22, certainly; This plug of two types should be selected a setting, but not is provided with simultaneously.

In order further to dwindle the volume of this preferred embodiment; The upper surface 21 of adapter 2 is provided with the storage tank 23 that is used for ccontaining double-legged flat plug 24 or double-legged circular plug 22; When both feet flat plug 24 or double-legged circular plug 22 leave unused, can it be rotated in the storage tank 23.

In sum, the utility model also is adapter and the automobile-used joint that lights a cigarette at integrated two types power supply change-over device, afterwards, has also merged the advantage of adapter and the automobile-used joint that lights a cigarette simultaneously, and obtains further outstanding advantage.In the utility model, an end of the automobile-used joint that lights a cigarette can keep good stable property, even run into bigger vibrations, also difficult drop-off; One end of adapter is through being integrated in plug its housing, can simplified structure, and reduced volume reduces cost.Therefore, after the common advantage that merges adapter and the automobile-used joint that lights a cigarette, the utility model not only has multiple input interface; And reasonable circuit layout, overall volume is dwindled greatly, and combination property significantly improves; It is comparatively convenient to carry, use all, because the dwindling of volume, parts integrated level are improved, the utility model also is able to obvious reduction at the cost of each links such as production, packing, transportation; Be beneficial to popularizing of the utility model, for more users facilitate.

Can know that by technological general knowledge the utility model can be realized through other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the utility model all comprised by the utility model.
