Elastic material.Wherein described elastic material is, for example, rubber, silica gel etc., can play the work of device in protective shell described in buffer protection
With.But the elastic material should avoid using to be held with the material of each device in the filter circuit plate or the material of the protective shell
The material easily chemically reacted.
In this present embodiment, the shape of the protective shell does not limit, for example, hemispherical, cuboid, square, cylinder
The distance between each device in the filter circuit plate of shape etc., each side wall of protective shell and protection should not be too big, described
The height of protective shell is advisable higher than 1mm to 5mm of each element height or so, and the material of the protective shell is, for example, PC, PBT etc..
In this present embodiment, the external wire can use conducting wire conventional in the prior art, in the present embodiment, by institute
Filter circuit plate is stated with signal input connecting pin and signal output connecting pin, accordingly, the external wire is included outside first
Connect 120 and second external wire 130 of conducting wire.
Wherein, one end of first external wire 120 is connected with the signal input connecting pin of the filter circuit plate, separately
One end is placed in outside the housing 110 through the housing 110, one end and the filtered electrical of second external wire 130
The signal output connecting pin connection of road plate, the other end are placed in outside the housing 110 through the housing 110.
In this way, having carried connecting wire equivalent to wave filter, wave filter is provided simultaneously with the function that filtering is connected with conducting wire.
In this present embodiment, it is the follow-up waterproof seal for improving integrated filter, the signal input connecting pin and institute
It is the gold-plated electrode (being commonly called as golden finger) being connected in the filter circuit plate to state signal output connecting pin, defeated as the signal
The gold-plated electrode one end for entering connecting pin is connected with the filter circuit plate (i.e. pcb board), the other end and first external wire
120 one end is connected, gold-plated electrode one end and the filter circuit plate (i.e. pcb board) phase as the signal output connecting pin
Even, the other end is connected with one end of second external wire 130.
Specifically, in this present embodiment, first external wire 120 through but not limited to hot pressing Anisotropically conductive adhesive tape,
Anisotropically conductive glue or hot melt adhesive film are fixed on the gold-plated electrode or are welded on the gold-plated electrode；Outside described second
Connect conducting wire 130 and be fixed on the gold-plated electricity through but not limited to hot pressing Anisotropically conductive adhesive tape, Anisotropically conductive glue or hot melt adhesive film
On extremely or it is welded on the gold-plated electrode.
Especially, in this present embodiment, the housing 110 is in injection molding, the 110 inside mould filling of housing,
It is sealed in outside the filter circuit plate and outside the external wire.Wherein, the housing 110 and the injection of the inside of the housing 110
Filling is integrally formed.
Specifically, as signal input connecting pin on first external wire 120 and the filter circuit plate
Gold-plated electrode be connected, in second external wire 130 and the filter circuit plate as the signal output connecting pin
After gold-plated electrode is connected, by the filter circuit plate, first external wire 120 and second external wire 130
It is put in the glue-injection machine for making the housing 110, the glue-injection machine is when injecting glue makes housing 110,110 shell of housing and housing
110 inside mould fillings are integrally formed, due to being injection molding, so housing 110 when injecting glue is formed with the filtered electrical
Road plate, first external wire 120 and second external wire 130 closely connect, the injecting glue inside the housing 110
Part is equivalent to being tightly wrapped in the filter circuit plate, first external wire 120 and second external wire 130
Outer surface, the connecting portion of 110 shell of housing and first external wire 120 and second external wire 130
Position is also injecting glue sealing, effectively improves the waterproofing grade of whole line concentration type wave filter 100.
Due to being equiped with protective shell outside each device in the filter circuit plate, elastic material is filled with again in protective shell,
So in 110 inside mould filling of housing, each device in the filter circuit plate will not be damaged.
In this present embodiment, the 110 inside mould filling of housing, it is outer and described external to be sealed in the filter circuit plate
The waterproofing grade formed outside conducting wire is IP67 or IP68.Be the equal of an entity in the housing 110, seamless space, because
And higher waterproofing grade can be reached.
Wherein, in this present embodiment, the material of 110 inside mould filling of the housing 110 and the housing is but unlimited
In nylon, polyvinyl chloride etc..
In this present embodiment, to save space, being applicable in more occasions, line concentration type wave filter described in the present embodiment 100
Volume is relatively small, occupies little space, and specifically, the altitude range of the housing 110 is preferably 2-3cm, and length range is preferred
For 8-10cm, width range is preferably 3-4cm.
The manufacturing process of the line concentration type wave filter 100 of the utility model is as follows：
First the combinations such as capacitive, perceptual filtering device are arranged in PCB circuit board, become the filtered electrical with filter function
Road plate, then PCB circuit board and external wire are attached, this connection are by external wire and PCB circuits by gold-plated electrode
Plate connects, and such a connection mode is the necessary connection mode that line concentration type wave filter 100 reaches IP67 waterproofing grade, afterwards,
By making the mould of the shell, PCB circuit board and external wire are wrapped up, are put in injection sealing, shaping in glue-injection machine.
In conclusion the line concentration type wave filter 100 of the utility model embodiment integrates the circuit board of conducting wire and wave filter
In one, and housing, in injection molding, the enclosure interior mould filling, it is outer and described to be sealed in the filter circuit plate
Outside external wire so that wave filter is possessing outside the function of filtering and conducting wire, can reach higher waterproofing grade, to filtering
The use of device brings great convenience, and unlimited use occasion；Each capacitive in filter circuit plate is filtered in the utility model
Protective shell is installed outside wave device and each perceptual filtering device, and elastic material is filled in protective shell so that the shell
Capacitive filtering device and perceptual filtering device are preferably protected during internal portion's mould filling；The utility model structure is novel, volume
It is small, it is economical and practical, there is higher market value and wide applicability.So the utility model effectively overcomes existing skill
Various shortcoming in art and have high industrial utilization.
The above embodiments are only illustrative of the principle and efficacy of the utility model, new not for this practicality is limited
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
Modifications and changes.Therefore, technical field includes usual skill without departing from the revealed essence of the utility model such as
God and all equivalent modifications completed under technological thought or change, should be covered by the claim of the utility model.
