Abstract
The utility model discloses tank commutator, the commutation copper sheet that circumference uniform distribution is laid is made including plastics core rod with at the cylindrical of plastics core rod, the top of commutation copper sheet is provided with bonding wire step, bonding wire groove offered by bonding wire step, it is dielectrically separated from by mica sheet between the sheet of adjacent commutation copper sheet, it is characterized in that: the top end face of plastics core rod is higher than the top end face of commutation copper sheet, the overhead height of mica sheet is less than the top face height of plastics core rod more than the top face height of commutation copper sheet, the top end face of commutation copper sheet forms the most independent semi-surrounding space after being isolated by mica sheet.This utility model can prevent diverter abnormal contact when installing between adjacent commutation copper sheet, reduces unexpected generation.
Description
Technical field
The utility model relates to the improvement invention of a kind of tank commutator.
Background technology
Tank commutator, makees, including plastics core rod with at the cylindrical of plastics core rod, the commutation copper sheet that circumference uniform distribution is laid, changes
Be provided with bonding wire step to the top of copper sheet, bonding wire groove offered by bonding wire step, is carried out by mica sheet between the sheet of adjacent commutation copper sheet
Being dielectrically separated from, the overhead height of mica sheet is equal to the top face height of commutation copper sheet.The tank commutator of said structure, at dress
After being fitted on rotor axis of electric, if motor-spin-coil requires that dripping glue processes, then glue is easy for along motor shaft in commutation
The top end face of copper sheet is scattered, and just has glue-contact between adjacent commutation copper sheet；Further, bonding wire groove is being attached wire
During bonding wire, the welding slag top end face at commutation copper sheet that likely drops makes to produce welding slag contact between adjacent commutation copper sheet, above-mentioned
Abnormal contact the work of diverter can be caused extremely disadvantageous impact.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide adjacent commutation copper sheet when one can prevent from installing
Between abnormal contact, reduce the unexpected tank commutator occurred.
This utility model has adopted the following technical scheme that:
Tank commutator, makees, including plastics core rod with at the cylindrical of plastics core rod, the commutation copper sheet that circumference uniform distribution is laid, changes
Be provided with bonding wire step to the top of copper sheet, bonding wire groove offered by bonding wire step, is carried out by mica sheet between the sheet of adjacent commutation copper sheet
It is dielectrically separated from, it is characterised in that: the top end face of plastics core rod is higher than the top end face of commutation copper sheet, the overhead height of mica sheet
Top face height more than commutation copper sheet is less than the top face height of plastics core rod, and the top end face of commutation copper sheet is by Muscovitum
The most independent semi-surrounding space is formed after sheet isolation.
After using technique scheme, the overhead height of mica sheet, more than the top face height of commutation copper sheet, so changes
Will be isolated by mica sheet to the top end face of copper sheet and form the most independent semi-surrounding space, though therefore have glue or
The top end face of commutation copper sheet fallen by welding slag, as there is the isolation of mica sheet, so preventing between adjacent commutation copper sheet
Abnormal contact, thus reduce unexpected generation.Further, since the overhead height of mica sheet is high less than the top end face of plastics core rod
Degree, so the intensity of mica sheet can be ensured.
As preferably, the top of mica sheet exceeds the height distance of commutation copper sheet top end face and controls at 2-3mm.
Accompanying drawing explanation
This utility model has a drawings described below:
Fig. 1 is top-direction view of the present utility model,
Fig. 2 is the A-A view of Fig. 1.
Detailed description of the invention
As it can be seen, tank commutator of the present utility model, justify including plastics core rod 1 with at the cylindrical of plastics core rod 1
The commutation copper sheet 2 that Zhou Junbu lays, the top of commutation copper sheet 2 is provided with bonding wire step 3, and bonding wire groove 5 offered by bonding wire step 3, adjacent
Being dielectrically separated from by mica sheet 4 between the sheet of commutation copper sheet 2, the top end face B of plastics core rod 1 is higher than the top of commutation copper sheet 2
End surface C, the top A of mica sheet 4 are highly more than the top end face C of commutation copper sheet 2 highly less than the top end face of plastics core rod 1
B height, the top A of mica sheet 4 exceeds the top end face C height distance of commutation copper sheet 2 and controls at 2-3mm, the top of commutation copper sheet 2
End surface C forms the most independent semi-surrounding space after being isolated by mica sheet 4.
