A large amount of research and development and certification cost are expended, and new installation dimension may be not easy to original installation, therefore, it is necessary to do into one
Step is improved.
Utility model content
The purpose of this utility model aims to provide that a kind of simple and reasonable, easy for installation, manufacturing cost is low, the scope of application
Wide power supply electric appliance function expansion module, to overcome weak point of the prior art.
A kind of power supply electric appliance function expansion module designed by this purpose, including it is connected to the functional module of power supply electrical equipment,
It is characterized in that：The functional module is arranged on the power supply out-put supply line of power supply electrical equipment, and the functional module includes circuit
Plate and insulation crust, circuit board are arranged in insulation crust, and are provided with Multifunctional battery charging control circuit on circuit board,
And/or one group of voltage x current output is converted into the Voltage to current transducer electricity of identical or different voltage x current output more than two
Road, or other functional circuits.
The circuit board is electrically connected with function input power cord, and the function input power cord is drawn outside insulation shell, and with
Power supply out-put supply line is connected.
The circuit board is electrically connected with a function above out-put supply line, and the fuction output power line draws insulation shell
Outside.
The utility model is realized by setting functional module on the power supply out-put supply line of power supply electrical equipment to power supply electrical equipment
Function expands；Multifunctional battery charging control circuit and/or voltage-current converter circuit are specifically set on circuit boards, and its
It controls circuit, wherein, one group of voltage x current output can be converted into more than two identical or different by voltage-current converter circuit
Voltage x current is exported；This functional module have automatic detection battery, timing charging, full of automatically shutting down, battery failures protection and
The functions such as overcurrent protection；In addition, this structure is the linkage function module in original structure, without changing original structure
And corresponding certificate of product certification, make its manufacturing cost low, it is convenient and applied widely to assemble.
Brief description of the drawings

Barrier protection and overcurrent protection；Automatic detection battery：Charging is not opened when cell voltage is too low or has been filled with；Timing is charged：Reach
Predetermined charging duration, automatically cuts off charging；Full of automatically shutting down：When charging current or voltage reach predetermined value, time delayed turn-off fills
Electricity；Battery failures are protected：Battery is charged to a certain magnitude of voltage and changes very hour for a long time, judges battery failures；Overcurrent protection：Fill
Shut-off charging when electric current is more than setting value.
Furtherly, circuit board is electrically connected with function input power cord 4, and the function input power cord 4 draws insulation shell
Outside, and with power supply out-put supply line 2 it is connected.
Furtherly, circuit board is electrically connected with a root functionality out-put supply line 5, and the fuction output power line 5 draws insulation
Outside housing.
Second embodiment
Referring to Fig. 3, this power supply electric appliance function expansion module is different from being in place of first embodiment：It is provided with circuit board
Voltage-current converter circuit, can be converted into what four groups of identical or different voltage x currents were exported, circuit by one group of voltage x current output
Plate is electrically connected with four root functionality out-put supply lines 5, and four root functionality out-put supply lines 5 are drawn outside insulation shell respectively, and other are not described
The same first embodiment in part.
Above-mentioned is preferred scheme of the present utility model, and general principle of the present utility model, principal character has been shown and described
