Abstract

The utility model relates to a transformer provided with a power source socket, comprising a main body, an input socket, a transformation rectifying circuit, an overload protection circuit, an external AC socket and a plug wire, wherein, the overload protection circuit is electrically connected with the input socket to facilitate the input of AC power sursce and avoid the heavy current load in the circuit; the external AC socket is connected with the overload protection circuit to facilitate the output of stable AC power source and the supply of AC power source to the external power socket. Since the transformer can be externally connected with expanded AC power output, a plurality of transformers can be implemented via being lapped with the external AC power in the way of co-stacking, and thereby the socket splicing positions are not occupied and a plurality of transformers can be jointly lapped with the external AC power source.

Description

Has the transformer that supply socket is provided with

Technical field

The utility model is about a kind of portable miniature transformer, especially a kind of transformer with supply socket setting.

Background technology

The structural representation of prior art transformer as shown in Figure 1, common general transformer 10 its inside are provided with the transformation rectification circuit, are used for converting input AC electricity (AC) to direct current (DC) output.Yet, this kind transformer is plugged in input AC in the supply socket, only single possess transformation rectification translation function, a socket position but accounts for, because electronic product day by day is subjected to liking and payes attention at present, need big power supply supply to use relatively, therefore exist a transformer use but can't expand the problem of its power supply supply usability.

Therefore, how to develop a kind of transformer that improves above-mentioned prior art disappearance, make it except that the function that possesses original transformation rectification, but also external AC output is used, real is the problem that needs research and development at present.

Summary of the invention

Main purpose of the present utility model is to provide a kind of portable type miniature transformer that the external AC accessory power outlet is provided; by on original member basis, setting up overload protecting circuit and external AC jack design; make it not only possess the transformation rectification function, and the socket function of the extendible formation energy of tool external AC output.

For reaching above-mentioned purpose, the transformer that the utility model provides a kind of tool supply socket to be provided with, it comprises body, input plug, transformation rectification circuit, overload protecting circuit and external AC socket, the built-in input plug of described body, transformation rectification circuit, overload protecting circuit and external AC socket, described input plug extrapolating is gone into input AC electricity in the supply socket, and described transformation rectification circuit connects input socket and input AC electricity conversion transformation is rectified into required DC power supply output; Described overload protecting circuit connects input socket and with the AC power input and avoid having on the circuit load of big electric current; Described external AC socket connects overload protecting circuit, supplies to make it can export stable AC power, and can supply defeated AC power by the external power supply joint.

Embodiment

Some exemplary embodiments that possess the utility model feature and advantage will be described in detail in the explanation of back segment.Be understood that the utility model can have various variations on different sample attitudes, its neither disengaging scope of the present utility model, and explanation wherein and to be shown in be when the usefulness that explain in essence, but not in order to restriction the utility model.

The transformer that the utility model provides a kind of tool supply socket to be provided with, Fig. 2 are to the utlity model has the transformer schematic appearance that supply socket is provided with; Fig. 3 is that the assembly that the utlity model has the transformer associated components of supply socket setting concerns schematic diagram; As shown in the figure, transformer 20 of the present utility model mainly comprises body 21, input plug 22, transformation rectification circuit 23, overload protecting circuit 24, external AC socket 25 and a patch 26.

Described body 21 built-in input plugs 22; transformation rectification circuit 23; overload protecting circuit 24 and external AC socket 25 are in wherein; described input plug 22 is that extrapolating is gone into input AC in the supply socket; described transformation rectification circuit 23 is to electrically connect with input plug 22; input AC electricity conversion transformation is rectified into required DC power supply to be exported by an end lead; described again overload protecting circuit 24 is to electrically connect with input plug 22; AC power can be imported and avoided having on the circuit load of big electric current; and described external AC socket 25 is to electrically connect with overload protecting circuit 24; for making it can export stable AC power; so; the load device of the external demand alternating current of external AC socket 25 energy; and make the external load device can avoid taking place the situation of large current load; the fail safe protection of power supply supply can be provided, be unlikely to cause the load device super-high-current damage for the transmission of electricity source.

Fig. 4 is the preferred embodiment schematic diagram that the utlity model has the external power supply of the transformer that supply socket is provided with, in the present embodiment, transformer of the present utility model have can be external the characteristic of expansion alternating current output, so load device can utilize its power connection 30 to be plugged in the stable AC power of transmission demand on the external AC socket 25, therefore the utility model transformer not only possesses the transformation rectification function, and the socket of its extendible formation energy external AC output, be plugged on the socket position that but do not account in the supply socket, have practical value and progressive.Can be used as (as: mobile phone etc.) are used in the charging of electronic product and be connected in transformer body 21 set connecting lines 26; Moreover the volume of transformer of the utility model is little, makes to close to go out to portably use.

Fig. 5 is the preferred embodiment schematic diagram of the mutual storehouse overlap joint of a plurality of transformers of the utility model external AC power supply.As shown in Figure 5, in the present embodiment, utilize transformer provided by the utility model have can be external the characteristic of expansion alternating current output, make a plurality of transformers implement in the mode of mutual storehouse overlap joint external AC, possesses the socket plug-in position that do not account for equally, but simultaneously again how transformer overlap the advantage of external AC power supply use together, also have practical value and progressive.

In sum; the transformer that the utility model provides the tool supply socket to be provided with; by on original member basis, setting up overload protecting circuit and external AC jack design; make it not only possess the transformation rectification function; and the socket of extendible formation energy external AC output; have industrial utilization and progressive, file an application in accordance with the law.

The utility model must be appointed by persons skilled in the art and executed that the craftsman thinks and be to modify as all, but neither scope of taking off the desire protection of claim institute.
