A kind of Switching Power Supply

Technical field

This utility model relates to a kind of electron electric power facility field, particularly to a kind of Switching Power Supply.

Background technology

Along with the high speed development of electronic technology, the application of various electronic equipments is more and more extensive, and its information processing rate is also More and more higher, supply voltage drops many times, and operating current is increasing, makes original power technology particularly commutation technique frequency Rate not in use by, this just proposes new higher requirement to power supply, and exchange type power arises at the historic moment.

Exchange type power is also Switching Power Supply, by controlling the time ratio that the vigilant pipe of switch turns on and off, remains steady Determine a kind of power supply of output voltage.Exchange type power is widely used almost all of with small-sized, light weight and high efficiency feature Electronic equipment, is that current electronics and information industry develops rapidly indispensable a kind of power mode.

Owing to the electric power environmental in countries in the world and area is different, mains voltage there is also difference, and the voltage of various countries' electrical equipment is fitted The most different by scope. common are 220V voltage and 110V voltage two kinds. the progress maked rapid progress along with world technology, among the people Exchange is more and more frequent, and two kinds of voltage forms of Switching Power Supply support the most slowly become certainty, bring to the Working Life of people Great convenience, and save fund, decrease the waste of the energy.

In prior art, directly voltage regulating element is arranged on circuit boards, at the housing near voltage regulating element Offer adjustment hole on wall, during concrete operations, need finger to stretch into adjustment hole, or use the unrelated thing such as pen core or toothpick Part stretches into adjustment hole, and fiddle with voltage regulating element, changes between two voltage gears.Such setting and not side And finger stretches into and also has certain risk in Switching Power Supply just,.

Therefore design a kind of Switching Power Supply that can regulate voltage gear quickly and easily and become problem demanding prompt solution.

Utility model content

The purpose of this utility model is to provide a kind of Switching Power Supply that can regulate voltage gear quickly and easily.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of Switching Power Supply, bag Including housing, housing bottom surface is connected with circuit board, and the edge of circuit board is close to housing sidewall inner surface, on circuit boards near shell The position of body sidewall is provided with voltage regulating element, and housing sidewall is provided with adjustment hole near the position of voltage regulating element, institute The housing exterior walls stated is provided with a groove, and the upper and lower surface of groove is equipped with spacing prominent, at groove and spacing prominent In going out formed slideway, sliding connection has a plectrum.

By using technique scheme, being embedded in the groove of housing exterior walls by plectrum, the outer surface of such housing does not has Having a prominent part, it is to avoid shell is inconvenient to situation about gripping, plectrum can substitute for finger and goes to stir operation voltage-regulation unit Part, and plectrum is removably mounted on shell, it is to avoid need additionally to carry the inconvenience of plectrum.

It is also preferred that the left described adjustment hole is positioned at inside the chute surface of groove, the higher primary school of adjustment hole is in the height of chute surface, plectrum Horizontally slip in slideway, when sliding into the position of adjustment hole, adjustment hole is completely covered.

By using technique scheme, when plectrum slides into the position covering adjustment hole, adjustment hole can be closed completely Closing, enclosure interior just constitutes a space closed, and protects housing interior structure, it is to avoid impurity dust is through adjustment hole Enter internal, when it also avoid transport or use, the damage possibly for internal structure that maloperation brings.

It is also preferred that the left be connected with shifting block on described plectrum front surface.

By using technique scheme, when finger stirs shifting block, plectrum will slide in slideway, it is to avoid finger is straight Connect plectrum plectrum, probably due to plectrum surface is the most smooth and dial motionless situation, facilitate operation.

It is also preferred that the left the upper and lower surface of described groove is provided with depression rounding structure, the upper and lower surface of plectrum is provided with accordingly Prominent rounding structure, both are mutually fitted together to, are slidably connected.

By using technique scheme, the upper and lower surface of plectrum is arranged to arc-shaped, not only allows the left and right of plectrum slide Dynamic more smooth, it also avoid plectrum when taking off operation, the danger of the sharpest edge incised wound finger.

It is also preferred that the left the upper and lower surface of described groove is provided with prominent gore, the upper and lower surface of plectrum is provided with accordingly The vee gutter of depression, both mutual tablings, be slidably connected.

By using technique scheme, the upper and lower surface of plectrum is arranged to the vee gutter of depression, makes plectrum with recessed Groove be slidably connected more tight, take off plectrum simultaneously, when using plectrum to stir voltage regulating element, can embed with fingernail The position of vee gutter, clamping plectrum is more firm, simplifies operation.

It is also preferred that the left the side of described groove is provided with a slip cambered surface, the sliding surface of groove passes through with housing outer surface Slip cambered surface connects.

By using technique scheme, when plectrum is taken out from groove, take out from the Slideslip having slip cambered surface, Slip cambered surface can make plectrum skid off more easily, it is to avoid during cambered surface of not sliding, plectrum is blocked by right-angle side and to take not Go out.

It is also preferred that the left described plectrum is provided with supplementary tumbler device in the side away from slip cambered surface, supplementary tumbler device is solid It is connected to plectrum.

By using technique scheme, supplementary tumbler device makes to stir voltage regulating element and is more prone to, saves behaviour The time made.

It is also preferred that the left described supplementary tumbler device is L-type, its one end is fixed in plectrum, and the other end is flat with the side of plectrum OK, the distance between the other end and plectrum side adapts with the width of voltage regulating element.

By using technique scheme, when stirring voltage regulating element, voltage regulating element is stuck in plectrum and auxiliary In the space that striking gear is formed, stir and be more prone to, decrease the possibility of maloperation.

It is also preferred that the left described supplementary tumbler device is rectangle, long limit is fixed in plectrum, and supplementary tumbler device center is offered There is the element bayonet socket adapted with voltage regulating element size.

By using technique scheme, when stirring voltage regulating element, by the element bayonet socket at supplementary tumbler device center Directly it is buckled on voltage regulating element, directly moves left and right plectrum and voltage regulating element just can be driven synchronously to move, simplify Operation.

It is also preferred that the left be coated with fluorescent material on described plectrum.

By using technique scheme, enclosure interior is dark, when fluorescent material makes plectrum stretch into enclosure interior, sends one Determining light facilitates operator to observe, and decreases the possibility of maloperation.

In sum, this utility model has the advantages that plectrum can substitute for finger and goes to stir enclosure interior Voltage regulating element, facilitates operation, and plectrum is removably mounted on housing exterior walls, it is to avoid carry other stirring The trouble of device, plectrum can cover on adjustment hole, the components and parts within protective housing.Plectrum is provided with supplementary tumbler device, Plectrum is coated with fluorescent material, all simplifies operation, saves the time.
