Description
Technical field
The utility model relates to a kind of filter, especially a kind of passive low ventilating filter.
Background technique
The filter circuit that power-supply filter is made of capacitor, inductance and resistance.Filter can be to specific in power supply line
Frequency other than the frequency point of frequency or the frequency point is effectively filtered out, and obtains the power supply signal of a specific frequency, or eliminate one
Power supply signal after a specific frequency.Known, the input of filter, output line need to pull open a certain distance, in order to avoid parallel,
The function of filter is influenced, the input of existing passive low ventilating filter, output line are all made of twisted-pair cable, due to the material of twisted-pair cable
Matter is softer, and the input of filter, output line is caused parallel phenomenon easily occur, seriously affects filter normal work.
Summary of the invention
In view of the deficiencies of the prior art, the utility model, which provides one kind, can effectively avoid input, output line from occurring parallel
Passive low ventilating filter.
The technical solution of the utility model are as follows: passive low ventilating filter, it includes main body, the first stereoplasm tube, the second hard
Pipe, input line, output line, the fire retardant insulating wing, unilateal conduction column and aluminium flake, the main body are rectangle structure, the main body
Left side is equipped with input terminal, and the right side of the main body is equipped with output end, the port punishment of the input terminal and output end
Not She You the first stereoplasm tube and the second stereoplasm tube, be enclosed with several input lines, second hard in first stereoplasm tube
Several output lines are enclosed in pipe, the two sides up and down of the main body are correspondingly arranged on the fire retardant insulating wing, the fire retardant insulating
The wing overlooks semicircular in shape, and the fire retardant insulating wing is equipped with unilateal conduction column, and the unilateal conduction column is on the fire retardant insulating wing
Lower end, the unilateal conduction column are simultaneously welded on the outside of main body inserted with an aluminium flake, the aluminium flake upper-end bent.
The aluminium flake is not through unilateal conduction column.
The material of the unilateal conduction column is the structure sheaf of the unilateal conduction fiber comprising thermosetting resin, " includes thermosetting
Property resin unilateal conduction fiber structure sheaf " be name of the applicant to this current material, not have work to the material
Any type of improvement out.The structure sheaf of the unilateal conduction fiber comprising thermosetting resin is compound disclosed in Chinese patent
The improvement of material, the structure of the documented unilateal conduction fiber comprising thermosetting resin of patent No. zl201080028367.4
Layer.
The material of the fire retardant insulating wing described in the utility model is fire retardant insulating composite material, and the fire retardant insulating is compound
Material is a kind of fire retardant insulating composite material disclosed in Chinese patent and its preparation process, application No. is: 201610967555.2,
Application No. is: 2016.10.31, the fire retardant insulating composite material of the record.
The installation method of the utility model are as follows: the fire retardant insulating wing of main body two sides is directly passed through into alite paste and is pasted onto needs
On the component of installation, main body is non-interference with installing component, and unilateal conduction column contacts with each other with installing component.
The working principle of the utility model are as follows: by being equipped with stereoplasm tube in output end and input terminal, can effectively prevent
Output line and input line are parallel；Known, passive low-voltage filter is typically mounted in electrical equipment, the general shell of electrical equipment
Ground connection, it is therefore an objective to will electric leakage, electrostatic be transmitted to ground wire, when ground wire open circuit, electrical equipment may gather high-pressure electrostatic, at this time by
In having unilateal conduction performance in unidirectional conductor column, for example longitudinal fiber is electrically conductive, and transverse fiber is non-conductive, therefore moment is
Conductive part conductive fiber (part of contact aluminium flake bottom end) can be burned out, to play protection low pressure passive filter
Effect.
The utility model has the following beneficial effects: the utility model is by being equipped with stereoplasm tube in output end and input terminal, it can
It effectively prevents output line and input line parallel, and then protects passive low ventilating filter, enable passive low ventilating filter just
Often work.
