Abstract
The utility model discloses a combined power supply filter which comprises a housing, input terminals and output terminals, wherein, a first power supply filter and a second power supply filter are arranged in the housing; the input terminals, as well as the output terminals, are divided into two groups, namely the first group and the second group; the input end and output end of the first power supply filter are respectively connected with the first group of input terminals and the first group of output terminals; and the input end and output end of the second power supply filter are respectively connected with the second group of input terminals and the second group of output terminals. The combined power supply filter has the advantages of compact structure, small size, light weight, good electromagnetic compatibility, good stability and the like.
Description
Technical field
The utility model relates to a kind of power-supply filter, particularly relates to a kind of compact conformation, combined electrical source filter that Electro Magnetic Compatibility is good.
Background technology
Along with developing rapidly of electronic technology; Arriving widely of electric equipment used, and electromagnetic environment is polluted and is on the rise, and more and more causes the extensive concern of world's all trades and professions; In a lot of fields, Electro Magnetic Compatibility has become technical indicator and the performance evaluation foundation that the Electrical and Electronic product must have.Power-supply filter can control electromagnetic interference effectively and electromagnetic radiation disturbs.Yet the filter major part of using now all is single filter, if equipment need use a plurality of filters, will receive the restriction in space, brings restriction for the development of electric equipment.
The utility model content
The purpose of the utility model be a kind of compact conformation is provided in order to address the above problem, volume is little, in light weight, Electro Magnetic Compatibility is good, the combined electrical source filter of good stability.
The utility model is realized through following technical scheme:
A kind of combined electrical source filter; Comprise shell, input terminal and lead-out terminal; Be provided with first power-supply filter and second source filter in the said shell; Said input terminal comprises first group of input terminal and second group of input terminal, and said lead-out terminal comprises first group of lead-out terminal and second group of lead-out terminal; The input of said first power-supply filter links to each other with said first group of input terminal; The output of said first power-supply filter links to each other with said first group of lead-out terminal; The input of said second source filter links to each other with said second group of input terminal, and the output of said second source filter links to each other with said second group of lead-out terminal.
As preferably, the electronic component of said first power-supply filter comprises 2 inductance and 5 resistance, and the electronic component of said second source filter comprises 1 inductance, 2 electric capacity and 3 resistance.
As preferably, said input terminal all links to each other with said shell through screw with said lead-out terminal.
The beneficial effect of the utility model is:
Through two kinds of different power-supply filters of model are integrated; Form the combined electrical source filter of an encapsulation; The volume that the volume ratio power-supply filter of combined electrical source filter takies when using separately is little; And the weight of combined electrical source filter is also light than two independent power-supply filters, and simultaneously, the Electro Magnetic Compatibility of the power-supply filter after the combination all increases than two power-supply filters that use separately with stability.In sum, the utlity model has compact conformation, advantages such as volume is little, in light weight, Electro Magnetic Compatibility is good, good stability.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1-shell, 2-fixed head, first group of input terminal of 3-, second group of input terminal of 4-, first group of lead-out terminal of 5-, second group of lead-out terminal of 6-, 7-inductance, 8-resistance, 9-electric capacity, 10-first power-supply filter, 11-second source filter.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify:
Of Fig. 1; The utility model combined electrical source filter comprises shell 1; Be provided with first power-supply filter 9 and second source filter 10 in the shell of power-supply filter; First power-supply filter, 9 electronic components comprise 2 electric capacity and 5 resistance, and second source filter 10 assemblies comprise 1 electric capacity, 2 inductance and 3 resistance.Through two kinds of different power-supply filters of model are integrated; Form the combined electrical source filter of an encapsulation; The volume that the volume ratio power-supply filter of combined electrical source filter takies when using separately is little; And the weight of combined electrical source filter is also light than two independent power-supply filters, and simultaneously, the Electro Magnetic Compatibility of the power-supply filter after the combination all increases than two power-supply filters that use separately with stability.Therefore, the utlity model has compact conformation, advantages such as volume is little, in light weight, Electro Magnetic Compatibility is good, good stability.
Lead-out terminal and input terminal lay respectively at the both sides of power-supply filter shell 1, and said input terminal links to each other with shell 1 through screw with said lead-out terminal.Input terminal comprises first group of input terminal 3 and second group of input terminal 4, and lead-out terminal comprises first group of lead-out terminal 5 and second group of lead-out terminal 6; The input of first power-supply filter links to each other with first group of input terminal 3; The output of first power-supply filter links to each other with first group of lead-out terminal 5; The input of second source filter links to each other with second group of input terminal 4, and the output of second source filter links to each other with second group of lead-out terminal 6.
