Description

Multichannel filter device of power manager

Technical Field

The utility model relates to an on-vehicle power supply, concretely relates to power manager's multichannel filter device.

Background

The vehicle-mounted power supply manager is centralized power supply and distribution equipment in a vehicle, and is mainly used for distributing one path of input direct-current power supply into a plurality of paths of equipment which are output to corresponding equipment in the vehicle for supplying power.

In order to meet the requirement of electromagnetic compatibility, power filters are required to be additionally arranged at the power input end and each path of output end, and the volume of each filter is correspondingly larger due to larger output current of each path. Traditional mode of installing additional is independently, dispersedly add at every way port, power manager has 1 power input port, 9 delivery outlets, need install 10 power filter additional, every power filter is different and the volume is different according to output characteristic, for obtaining satisfied electromagnetic compatibility effect, every filter should install nearby at the input, output port department, and every filter self shields and ground is good, install like this and can greatly occupy power manager internal assembly space additional, cause the internal assembly space utilization not enough, and the wiring is many, it is complicated, the assembly operation is inconvenient.

SUMMERY OF THE UTILITY MODEL

Problem to prior art exists, the utility model aims to solve the technical problem that a power manager's multichannel filter device is provided, it can solve each wave filter independently among the power manager, add at every way port dispersedly, installation occupation space is big, causes that interior assembly space utilization is not enough, the wiring is complicated, the assembly operation is inconvenient, electromagnetic compatibility effect subalternation problem

The utility model aims to solve the technical problem that the technical scheme is realized through such a technical scheme, it includes the box body, outside panel and inside socket shell closing cap box body front and back respectively, install filter circuit board in the box body, a plurality of filter circuit have been laid on the filter circuit board, power input socket and each single power output socket are equipped with on the outside panel, the inside socket of connecting the internal work circuit of power manager is equipped with on the inside socket shell, power input socket XS1 electric wire of outside panel inserts a filter circuit input on the filter circuit board, the output lead wire of this filter circuit connects on the inside socket J1 of inside socket shell; the internal sockets on the internal socket shell are connected with the power supply outputs in the power supply manager, and are sequentially connected with the corresponding filter circuit input ends on the filter circuit board through leads, and the output end leads of each filter circuit are respectively connected with the power supply output sockets on the external panel.

Further, an input reverse connection prevention circuit and a lightning protection circuit are arranged between the power input socket XS1 and the filter circuit thereof.

Because the utility model adopts the above technical scheme, carry out effectual integration with power manager's multichannel power filter and other functional circuit, carry out compact overall arrangement with power input, output socket to install the rear panel at the power manager box ingeniously, greatly saved power manager box inner space, and the assembly is simple, and electromagnetic compatibility is effectual.

The utility model has the advantages that: the circuit and the device are reasonable in layout, simple in assembly, high in integration level, small in size, light in weight and good in electromagnetic compatibility effect.
