Abstract
The utility model relates to a multifunctional fluctuation transformer, which comprises a transformer, and a housing is arranged outside the transformer. The fluctuation transformer is characterized in that a sheath is respectively arranged in the front or on the back of the housing of the transformer; an alternating current output socket electrically connected with the transformer is mounted at the upper end of one sheath and a USB interface is mounted at the upper end of the other sheath; the USB interface is electrically connected with a DSP chip and a PCB capable of offering 100MA-300MMA current; then, the PCB is connected with a power supply; a support leg is respectively arranged below the front and the back sheathes; and the entire transformer is connected as a whole through bolts. The multifunctional fluctuation transformer overcomes the disadvantages of onefold function of original products; and not only can ensure that a user obtain the needed alternating current power supply under various power networks and voltages, but also can provide direct current for numerous digitized portable device, thereby bringing convenience to people in official business handling and daily life.
Description
Technical field
The utility model relates to a kind of interchange step transformer.
Background technology
Exchanging step transformer is a kind of general AC transformation device, can make various power consumption equipments by this device, as: state-run equipment and lighting apparatus such as household electrical appliance such as video tape recorder, colour TV, television set, sound system and computer, photocopier, program controlled telephone, the convenient use under the different voltages of different countries and regions.But along with the renewal day by day of general series interface (USB) technology, the digitlization portable set day by day increases, and USB interface has been come into huge numbers of families, and does not still have above-mentioned interface in the prior art interchange step transformer, to feeling inconvenience in people's work and the life.
Summary of the invention
The utility model main purpose is to solve existing in prior technology inconvenience, thereby develops a kind of multifunctional lifting transformer with general series interface function.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of multifunctional lifting transformer, has transformer, there is sheath body the transformer outside, it is characterized in that: respectively there is an involucrum transformer sheath body front and back, the accessory power outlet that is electrically connected with transformer is equipped with in an involucrum upper end therein, the general series interface is equipped with in another involucrum upper end, it is USB interface, described USB interface is with digital signal processor (dsp chip) and can provide the printed board (PCB) of 100mA ~ 500mA electric current to be electrically connected, and PCB is connected with power supply again; A leg is respectively arranged below forward and backward involucrum, and top two angles of whole transformer connect transformer, involucrum with bolt, below two angles with bolt transformer, involucrum, leg are connected.
Therefore, the beneficial effects of the utility model are: owing to increased the general series interface on step transformer, it is simple in structure, and is easy to make; Both solved the deficiency of original product function singleness, the AC power that the user can be needed under different line voltages separately can also be directly for numerous digitlization portable sets provide direct current, thereby have brought facility for people's office and life.
Description of drawings
Accompanying drawing 1 is a kind of structure split schematic diagram of the present utility model.
Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Step transformer as shown in Figure 1, be with sheath body 6 in transformer 5 outsides, at the two ends of transformer an involucrum 7 is arranged respectively, the involucrum 7 on one side links to each other with the alternating current by transformation, and realize by the interchange output of socket 13 Insurance Block 8 being housed also in the involucrum, in the seat fuse 9 and plug screw 10 are arranged, 12 is Illuminated Switch, and 11 is power line sheath circle; The another side of involucrum 7 is the PCB district, and the general series interface is with digital signal processor and can provide the printed board 4 of 100mA ~ 500mA electric current to be electrically connected, the 3rd, and dividing plate, the power supply input is passed through transformer 5 and is its power supply, thereby realizes the direct current output by the USB hole.Respectively there is a leg 1 involucrum 7 lower ends on both sides, are connected into integral body with 4 bolts 15 between transformer 5, involucrum 7, the leg 1.
When input had alternating current, socket aperture 13 just had corresponding conversion alternating voltage output, and simultaneously by PCB, USB interface has had the output of 5V direct current.At this moment, USB indicator light red light lights.When providing power source charges for its portable set, when being full of, USB indicator light green light lights, and has played the generation that prevents to overcharge phenomenon.
