Embodiment

Referring to description of drawings, the utility model is further specified:

Referring to Fig. 1, Fig. 2; A kind of multidigit charger; Comprise pedestal 1 and be installed on circuit electroplax and the attaching plug 5 on the pedestal 1, wherein the circuit electroplax comprises two groups of charging circuits at least, and pedestal 1 is provided with the charge position corresponding with above-mentioned charging circuit; Each charge position comprises a Battery pack installed surface 16, a sliding tray 2 and a plastic clip 3 that is used for fixing battery 6; Be provided with the sliding contact 4 that can in sliding tray 2, do linear movement in the above-mentioned sliding tray 2, the installed surface of the bearing of trend of sliding contact 4 and battery 6 is not parallel, and this sliding contact 4 links to each other with the output of charging circuit; As a kind of specific embodiment; Angle between the bearing of trend of sliding contact 4 and battery 6 installed surfaces is the 5-60 degree, and the quantity of charge position is 2-6, is preferably 4 in the present embodiment; Each said charge position is provided with the photoflash lamp 15 that is used to represent this charge position charged state; Above-mentioned four are charged as and are matrix pattern and are uniformly distributed in base-plates surface, and the inclined-

plane

161 and 162 that is arranged on the pedestal is positioned at same plane, and this plane is the battery installed surface 16 of battery 6.

Said base 1 comprises as a whole lid of socket 17 and housing 18; Said plastic clip 3, sliding tray 2 are arranged on the lid 17; The circuit electroplax is arranged in the housing 18, and housing 18 is provided with the groove that is used to hold attaching plug 5 at end position, and attaching plug 5 is rotationally connected with on the sidewall of groove;

Plastic clip 3 is rotationally connected through plastic clip axle 11 and lid 17, and plastic clip axle 11 is provided with and is used to force plastic clip 3 movable ends to compress the spring 32 of lid 17, and spring 32 is fixed on the lid 17 at spring fixing point 13 places through spring keeper 12;

Said sliding contact 4 is provided with the handle 41 that is used to regulate slide displacement, and said handle 41 extends sliding tray 2 and is provided with insulating case at tip position.

Based on above structure, the multidigit charger under the utility model is stirred attaching plug 5 earlier and is made it to turn over 90 degree when work; Energized, luminous like power lights 14, the power supply on then is described; The user selects one arbitrarily in above-mentioned four charge position, the afterbody of pressing plastic clip 3 makes its chuck 31 opened with certain angle and battery 6 is positioned over the appropriate location on the inclined-plane 16, the handle 41 of adjustment sliding contact 4 ends; Sliding contact 4 is inserted in the slot electrode of batteries 6, as this moment photoflash lamp 15 dodging, explain that then battery has got into charged state; When treating that photoflash lamp 15 stops to glimmer, explain that battery has been full of the desirable usefulness of sening as an envoy to; Fill the polylith battery like needs, then repeat above step in other charge position and get final product, the charging process of each charge position is independently controlled, and does not receive the influence of other charge position.

As need not charge the time, pull up attaching plug 5 deenergizations and with attaching plug 5 clawbacks in the groove of housing 18.

Referring to Fig. 3, the described charger of the utility model adopts vibration to suppress code converter (RCC circuit); Its control procedure and continuous nonlinear change; But do definite value output according to the output voltage variation of Switching Power Supply, and specifically, its output state has two kinds: the one, when switch power source output voltage surpasses definite value; The impulse controller output low level, switching tube ends; The 2nd, when switch power source output voltage is lower than rated value, impulse controller output high level, switching tube conducting.When load current reduced, filter capacitor prolonged discharge time, and output voltage can not reduce very soon; Switching tube is in cut-off state; Be reduced to below the rated value up to output voltage, switching tube is conducting once more, depends on the size of load current the deadline of switching tube; Being controlled from the output voltage sampling by level switch by conducting of switching tube, therefore this power supply is also claimed the aperiodicity Switching Power Supply.

In charging process, the 220V civil power is through D ₁-D ₄Behind the bridge rectifier, at Q ₂Collector electrode on form the direct voltage about a 300V because Q ₂Form blocking oscillator with switch transformer, the direct voltage about the 300V of start back is added to Q through primary ₂Collector electrode, this voltage also passes through starting resistance R simultaneously ₂Be Q ₂Base stage a bias voltage is provided because positive feedback effect, Q ₂I _CRise rapidly and saturated, at Q ₂Get between the off period, the induced voltage that the switch transformer secondary winding produces makes D ₇Conducting, and the direct voltage to about 6-8V of load output.The inductive impulse that the feedback winding of switch transformer produces is through D ₅Rectification, C ₁Produce after the filtering one with the proportional direct voltage of oscillating impulse number, if this voltage is above voltage-stabiliser tube D ₁₇Voltage stabilizing value D ₁₇Just conducting, this negative polarity commutating voltage just is added in Q ₂Base stage it is ended rapidly, Q ₂Deadline and its output voltage be inverse ratio.D ₁₇Conducting (or by) directly receive the influence of line voltage and load, line voltage is low more or load current is big more, D ₁₇ON time short more.Q ₂ON time long more, otherwise line voltage is high more or load current is more little, D ₅Commutating voltage high more, D ₁₇ON time long more, Q ₂ON time short more, Q ₁Be the overcurrent protection pipe, R ₅Be Q ₂I _eSample resistance.Work as Q ₂I _eWhen excessive, R ₅On voltage decreases make Q ₁Conducting, Q ₂End, can effectively eliminate the start impulse current of moment, simultaneously to D ₁₇Controlled function also be a kind of compensation.Be input in the transformer thereby controlled energy, also just controlled the rising of output voltage, realized the function of voltage stabilizing output.

D ₁₇Control Q with voltage sampling ₂Duration of oscillation, and Q ₁Be to control Q with current sampling ₂Duration of oscillation, the transformer secondary output winding is made up of many groups of identical windings; In order to the purpose that realizes a plurality of batteries are charged simultaneously; Every group induced current is through behind the rectifier diode and filter capacitor filtering of each group, and the voltage (zero load) about output 6-8V supplies the battery charging.

Should be appreciated that; The utility model institute protection range is not limited to above specific embodiment, and what all those skilled in the art of belonging to need not that creative work can implement all should fall within the protection range of the utility model based on the technical scheme of the utility model and the modification of technological means.
