The utility model discloses a filter assembly possessing the power supply filtering function and the signal filtering function. The filter assembly includes a housing, an input terminal, and an output terminal. The inside of the housing is provided with an integrated circuit board. The integrated circuit board is provided with a power supply filtering element and a signal filtering element. An input terminal of the power supply filtering element and an input terminal of the signal filtering element are correspondingly connected with an internal terminal of the input terminal respectively. An output terminal of the power supply filtering element and an output terminal of the signal filtering element are correspondingly connected with an internal terminal of the input terminal respectively. The filter assembly is reasonable in structural design, small in volume, light in weight, excellent in conducting effect, strong in anti-interference capability, and is easy to install.
Description
Technical field
The utility model relates to a kind of filter assembly, relates in particular to a kind of filter assembly with power filter and signal filtering function.
Background technology
Along with constantly application and development of electronic apparatus system in recent years, make electromagnetic environment increasingly sophisticated, in complex electromagnetic environments, various device or system realize the compatible and normal and stable work of battery, come into one's own day by day.Electromagnetic compatibility refers generally to electric and electronic equipment can be carried out the coexisting state of function separately in common electromagnetic environment, and operate as normal and not disturbing mutually reaches " compatibility ".Electromagnetic compatibility is a kind of ability of equipment, and it can be accomplished the function of self and be unlikely the unallowed interference of generation in its environment in its electromagnetic environment.In order to realize the inside and outside Electro Magnetic Compatibility of automation control system, need to take measures from technology and tissue respectively: at first, will analyze the electromagnetic interference three elements exactly technically, suppress interference source, reduce unnecessary emission; Eliminate or weaken interference and coupling; Increase the antijamming capability of sensitive equipment, weaken unnecessary response, like ground connection, shielding, filtering amplitude limit etc.In addition, from organizing consideration, need to set up certification authority and work out corresponding standard.Power-supply filter and traffic filter can both be used for antijamming capability electric and that electronic equipment mainly solves the noise suppressed on the machine operation power line and improves signal.Yet signal filtering at present all is split type with power filter, filtering body and use the external interface of equipment also to be split-type structural, and the electric interfaces form is single.
The utility model content
The purpose of the utility model is that a kind of reasonable in design, volume is little, in light weight, easy for installation, conducting effect is good and the signal antijamming capability the is strong filter assembly with power filter and signal filtering function are provided in order to address the above problem.
The utility model is realized through following technical scheme:
A kind of filter assembly with power filter and signal filtering function; Comprise shell, input terminal and lead-out terminal; Be provided with surface-mounted integrated circuit in the said shell; Power filter element and signal filtering element are installed on the said surface-mounted integrated circuit, the input of said power filter element and said signal filtering element respectively with inner corresponding connection of said input terminal, the output of said power filter element and said signal filtering element respectively with inner corresponding connection of said lead-out terminal.
As preferably, said lead-out terminal comprises power filter lead-out terminal and signal filtering lead-out terminal, and the outer end of said power filter lead-out terminal and said signal filtering lead-out terminal is connected with respectively and is used for the outside lead that is connected.
As preferably, said power filter lead-out terminal and said signal filtering lead-out terminal are arranged at the side of said shell respectively.
As preferably, said input terminal is a porous socket.
The beneficial effect of the utility model is:
Through power-supply filter and traffic filter are combined in the filter assembly; Take side connecting conductor formula and inner being connected of consumer products simultaneously; Efficiently solve the power supply conducted interference problem of subscriber equipment, also improved the signal handling capacity and the antijamming capability of equipment.That the utility model also has is easy for installation, volume is little, lightweight advantage.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of the utility model;
Among the figure: 1-input terminal, 2-signal input element, 3-surface-mounted integrated circuit, 4-signal filtering lead-out terminal, 5-lead, 6-shell, 7-power supply input element, 8-power filter lead-out terminal.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify:
As illustrated in figs. 1 and 2; The utlity model has the filter assembly of power filter and signal filtering function; Comprise shell 6, input terminal 1 and lead-out terminal 9; Be provided with surface-mounted integrated circuit 3 in the shell 6; Power filter element and signal filtering element are installed on the surface-mounted integrated circuit 3, the input of power filter element and signal filtering element through power supply input element 7 and signal input element 2 respectively with inner corresponding connection of input terminal 1, the output of power filter element and signal filtering element respectively with inner corresponding connection of lead-out terminal.Lead-out terminal comprises power filter lead-out terminal 8 and signal filtering lead-out terminal 4, and the outer end of power filter lead-out terminal 8 and signal filtering lead-out terminal 4 is connected with respectively and is used for the outside lead 5 that is connected.Power filter lead-out terminal 8 and signal filtering lead-out terminal 4 are arranged at the side of shell 6 respectively.The input terminal 1 of filter assembly is a porous socket.
Through power-supply filter and traffic filter are coupling on the circuit circuit board in the filter assembly; Take side connecting conductor formula and inner being connected of consumer products simultaneously; Efficiently solve the power supply conducted interference problem of subscriber equipment; Solve its product electromagnetic compatibility problem, also improved the signal handling capacity and the antijamming capability of equipment.Through long-time use, meet the demands; The test in the code test chamber simultaneously, the requirement of product electromagnetic compatibility sexual satisfaction GJB151A standard.This aerial lug performance is high, can be widely used in various micro-machines, airborne equipment, other various military equipments.
The above preferred enforcement that is merely the utility model that discloses can not limit the claim scope of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
