Abstract
The utility model relates to a novel charger which is mainly suitable for charging various rechargeable storage batteries. The utility model mainly comprises a charging circuit, a charger input, a charger output, a switch and an outer shell, wherein, the charging circuit is arranged in the outer shell so that a sealed type is formed, and the charging circuit is composed of a capacitor, a full wave rectification circuit and a voltage stabilizing split-flow circuit. The novel charger can be used for hermetically and safely charging the rechargeable storage batteries after mains supply alternating current and alternating electric current which is generated by the charge and discharge of the capacitor and has the same frequency to carry out full wave rectification are used. The novel charger has the characteristics of low self heat, high charging efficiency, large retractility of chargeable voltage, simple structure, safe utilization, etc.
Description
The utility model relates to a kind of charger, mainly is applicable to various rechargeable type storage batterys are charged.
Existing charger generally is made of circuit such as transformation, rectification, voltage stabilizings, because of being furnished with transformer, so volume is bigger.
The purpose of this utility model is a kind of New-type charge device of design, utilizes capacitor charge and discharge, can be directly charges to several rechargeable type storage batterys to 1 for alternating current with the city.
The New-type charge device mainly includes charging circuit, charger input and output, switch and shell, charging circuit places and constitutes sealed type in the housing, charger input and output are drawn by charging circuit and are arranged on the housing, and charging circuit is by capacitor C, bridge full wave rectifier D
1-D
4Form with the voltage stabilizing shunt circuit of forming by one group of diode D.Directly use the city to input to capacitor C for alternating current by input, the alternating current that utilizes same frequency that capacitor charge and discharge produces is to D
1-D
4, carry out full-wave rectification, by output output, the rechargeable type storage battery is carried out the sealingly secure charging to D voltage stabilizing shunting back.Can be furnished with a two-way ganged switch at the charger output, be used to control the unlatching of charger output and storage battery, storage battery and electrical appliance (or storage battery output) with closed.When storage battery uses, disconnect with charger, charger can not charge, and alternating voltage does not relate to the exposed parts of battery; When charge in batteries, disconnect with electrical appliance (or storage battery output), the battery exposed parts cuts off, to reach safe charging.
The utility model adopts capacitance current-limiting, and low because of charger self pressure drop, it is very little to generate heat, so the charge efficiency height; Because of utilizing capacitor charge and discharge to produce, utilize line voltage, so chargeable pressure retractility is big with the frequency alternating current; Charger circuit is simple, and volume is little; Charger is adopted sealing charging and the control of two-way ganged switch, safe and reliable, applied range, easy to use.
Accompanying drawing is New-type charge device electrical schematic diagram (comprising the output of storage battery and storage battery)
Embodiment is referring to accompanying drawing.Be made of charging circuit, charger input and output, switch and shell, charging circuit places sealed insulation in the housing, by capacitor C, bridge rectifier D
1-D
4, voltage stabilizing shunt circuit D forms, charger input and output are drawn by charging circuit and are arranged on the housing, and the charger input is established plug, are used for directly inserting the city and charge for AC Power supply socket, output is that socket is arranged on the housing, can charge to various storage batterys.Be furnished with a two-way ganged switch at the charger output, K switch is located on the shell, is convenient to operation.Capacitor C adopts ac resistance to press more than the 250V, and the charger input is equipped with corresponding fuse, with guarantee to use go up safe and reliable.The voltage stabilizing shunt circuit adopts one group of diode to form, and its quantity and storage battery number are complementary, and to reach the batteries of various different voltages are protected charging.
Charger can be made stand-alone product, is used for various storage battery is carried out the sealingly secure charging, also can be made of one with storage battery, becomes the chargeable source of sealed type, directly is loaded on the electrical appliance.
