Abstract

The utility model relates to a multipurpose AC resistance-value regulation model, which is composed of a casing, capacitors and lead wires, wherein, the capacitors are sealed and fixed in the casing, one end of each capacitor is connected in parallel with ends of other capacitors and a lead wire is led out to the casing from the connecting point, and the other end respectively lead out a lead wire to the casing from each capacitor. When using, each capacitor is connected in series with a start. By combining different capacitors, the regulation of the AC resistance value can be realized so as to regulate voltages and currents.

Description

A kind of many with exchanging the resistance adjustment module

The utility model relates to a kind of interchange resistance trim, especially for the interchange resistance trim of charger, belongs to electronic technology field.

At present, the decompression transformation device generally adopts transformer in various power consumption equipments, and its effect is that input voltage is dropped to required voltage from high pressure, also has to adopt capacitance decompression, and its mechanism is the purpose that reaches step-down by the AC impedance of electric capacity.Compare these two kinds of schemes, the former volume is big and heavy, and the latter only can provide a kind of fixing AC impedance, can not provide different AC impedance or pressure drops for power consumption equipment.

The purpose of this utility model is to provide a kind of interchange resistance adjustment module, and it can provide convenience the interchange resistance adjustable for the needs of multiclass electricity consumption device.

The purpose of this utility model is realized by following technical scheme:

A kind of many with exchanging the resistance adjustment module, it is made up of housing, electric capacity and the lead-in wire of sealing, electric capacity is 4, its capacity is respectively C1=1-5 μ F, C2=2-20 μ F, C3=5-50 μ F, C4=10-100 μ F, one end of described electric capacity links together, outwards draw a lead-in wire by housing, the other end of each electric capacity is then drawn 4 lead-in wires respectively outside housing, the lead fairlead is arranged on the sidewall of housing.

Adopt the many of said structure, can replace volume and weight and all show heavy transformer with exchanging the resistance adjustment module.When being used for needing the electricity consumption device (for example charger) of different input voltages (or resistance), can change it and exchange resistance by connection in series-parallel different electric capacity, finally reach the purpose of regulation voltage or resistance.This module is because of lumping together a plurality of capacitance group, and the selection of holding value parameter is that needs according to rechargeable battery commonly used carry out, so adaptation face width, convenience and practicality.It both had been applicable to common rechargeable battery, also had been applicable to the needs of storage batterys such as motor, tractor or automobile charging.In addition, it also has advantage simple in structure, with low cost.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

As we can see from the figure, many be made up of housing 1, electric capacity 2,3,4 in lead-in wire with exchanging the resistance adjustment modules, it both can utilize existing electric capacity that it is packaged together, and also can utilize the electric capacity manufacturing process, and the capacitor of several different capabilities is manufactured in together.Common junction after each capacitor parallel connection is outwards drawn a common lead, and the other end of each electric capacity is drawn a lead-in wire respectively outside housing.The electric capacity that is encapsulated in the housing can adopt 4-10 as required, and present embodiment is 4.In order to reach the purpose that is fit to different output current, the capacity of electric capacity should be done special selection, and present embodiment is C1=1-5 μ F, C2=2-20 μ F, C3=5-50 μ F, C4=10-100 μ F according to the capacitance of parametric optimization commonly used.The leaded fairlead 5 of the sidewall of housing or 6 can be drawn electric capacity.In use, the lead-in wire 4 of each electric capacity can connect K switch 1-K4 respectively, utilizes the break-make of these switches, can form various common combinations easily.It is used to adjust the pressure drop of charger, can obtains 15 kinds of different current values between the 0.14A-2.5A, regulate, can satisfy the needs of charger commonly used basically with the level that has that realizes electric current.
