Description
Technical field
The invention belongs to filter fields, and in particular to hollow wave filter housing.
Background technology
At present, being widely used in daily life with wave filter, the demand of wave filter is also increasing.It is but traditional
The production of the magnet ring of wave filter can not be realized automatically, need a large amount of manpower, and production cost is high, while the magnetic produced
The consistency of ring is poor so that the wave filter quality produced differs, and influences the overall quality of wave filter.
Invention content
The technical problems to be solved by the invention are just to provide outside a kind of hollow wave filter of achievable Full-automatic coiling
Set.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：Hollow wave filter housing, including mutually splicing
Upper protective shell and lower protective shell, upper protective shell is identical with lower protective shell shape and is wrapped on hollow magnetic core, upper protective shell
Annular projection is both provided on the face opposite with lower protective shell, two annular projections are spliced into the intermediate skeleton for wave filter and pass through
Limit hole.
Further, upper protective shell and lower protective shell are by being arranged on the first slot of upper protective shell and lower protective shell both sides
With the first inserted sheet grafting.
Further, annular projection includes two splice plates parallel with inserted sheet and two limitings vertical with inserted sheet
Plate, limiting plate are stepped.
Further, two annular projections pass through the second slot and the second inserted sheet grafting.
Further, hollow magnetic core includes the connection of the winding section and connection two winding sections both ends of two winding coils
The opening for exposing connecting portion is provided on portion, upper protective shell and lower protective shell.
Further, the material of upper protective shell and lower protective shell is plastics.
Compared with prior art, the beneficial effects of the invention are as follows：
By the way that by hollow wave filter outer sheath covers, in the outside of magnetic core, coil is put on around being located at outside hollow wave filter,
Upper protective shell and lower protective shell separate coil and magnetic core, and magnetic core during coiling is avoided to cause pressure resistance bad to the damage of line,
It can increase pressure resistance of the product line to magnetic core simultaneously, improve the quality of wave filter, be wrapped up outside hollow wave filter on the outside of magnetic core
Set so that wave filter can be tested by being struck by lightning, and improve the performance of wave filter.

Specific embodiment
The embodiment of hollow wave filter housing of the present invention is described further referring to figs. 1 to Fig. 3.
Hollow wave filter housing, including the upper protective shell 1 mutually spliced and lower protective shell 2, upper protective shell 1 and lower protective shell
2 shapes are identical and are wrapped on hollow magnetic core 7, and annular projection is both provided on upper protective shell 1 and the opposite face of lower protective shell 2
3, two annular projections 3 be spliced into the intermediate skeleton for wave filter by limit hole 4, the side wall of limit hole 4 and wave filter
Skeleton offsets so that upper protective shell 1, lower protective shell 2 and the hollow magnetic being clamped between protective shell 1 and lower protective shell 2
Core 7 can not be on occurred level direction on the skeleton of wave filter displacement, connect more stable and firm, upper protective shell 1 and lower guarantor
Protective case 2 is by being arranged on 52 grafting of the first slot 51 and the first inserted sheet of upper protective shell 1 and lower 2 both sides of protective shell so that upper to protect
Connection between protective case 1 and lower protective shell 2 is even closer securely, and annular projection 3 includes two spellings parallel with the first inserted sheet 52
Fishplate bar 31 and two limiting plates 32 vertical with the first inserted sheet 52, limiting plate 32 is stepped, when two stair-stepping limitings
When plate 32 is stitched together, protective shell 1 and lower protective shell 2 can be effectively prevent to be moved up along the direction perpendicular with the first inserted sheet
It is dynamic, it ensure that the stability that annular projection 3 connects, two annular projections 3, can by 62 grafting of the second slot 61 and the second inserted sheet
The further connection between two annular projections 3 of locking so that upper protective shell 1 and lower protective shell 2 stabilization are socketed in hollow magnetic
The outside of core 7, hollow magnetic core 7 include the connecting portion of the winding section and connection two winding sections both ends of two winding coils, on
The opening for exposing connecting portion is provided on protective shell 1 and lower protective shell 2, when the upper protective shell 1 for thinking separately closely to be stitched together
During with lower protective shell 2, the two can need to only be separated by opening, simple to operate, upper protective shell 1 and lower protective shell 2
Material be plastics so that the magnetic core for being socketed with protective shell 1 and lower protective shell 2 may conform to safety requirement without plastic-coated,
Improve magnetic security performance.
By the way that by hollow wave filter outer sheath covers, in the outside of magnetic core, coil is put on around being located at outside hollow wave filter,
Upper protective shell 1 and lower protective shell 2 separate coil and magnetic core, and magnetic core during coiling is avoided to cause pressure resistance to the damage of line not
It is good, while pressure resistance of the product line to magnetic core can be increased, the quality of wave filter is improved, hollow wave filter is wrapped up on the outside of magnetic core
Housing so that wave filter can be tested by being struck by lightning, and improve the performance of wave filter.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
