Abstract

The utility model discloses a kind of 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, injected phenolic moulding powder between the sheet between sheet by plastics core rod between the sheet of adjacent commutation copper sheet to be dielectrically separated from, it is characterized in that: the top end face of plastics core rod is higher than the top end face of commutation copper sheet, between sheet, the top of phenolic moulding powder has top extension upwards, between the sheet after upwardly extending, the overhead height of phenolic moulding powder is as the top face height of plastics core rod, the top end face of commutation copper sheet forms the most independent semi-surrounding space after the top of phenolic moulding powder extends isolation between sheet.This utility model can prevent diverter abnormal contact when installing between adjacent commutation copper sheet, reduces unexpected generation.

Description

A kind of tank commutator
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, has to be entered by mica sheet between the sheet of adjacent commutation copper sheet Row is dielectrically separated from, and also has and injects what phenolic moulding powder between the sheet between sheet carried out being dielectrically separated from by plastics core rod.By bakelite between sheet Powder carries out the tank commutator being dielectrically separated from, and between sheet, the overhead height of phenolic moulding powder is equal to the top face height of commutation copper sheet.On State the tank commutator of structure, after being assembled on rotor axis of electric, if motor-spin-coil requires that dripping glue processes, then glue Water is easy for being scattered along motor shaft at the top end face of commutation copper sheet, just has glue-contact between adjacent commutation copper sheet;Further, Bonding wire groove is when being attached the bonding wire of wire, and the top end face that welding slag likely drops at commutation copper sheet makes adjacent commutation copper sheet Between produce welding slag contact, the work of diverter can be caused extremely disadvantageous impact by above-mentioned abnormal contact.
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:
A kind of tank commutator, makees, including plastics core rod with at the cylindrical of plastics core rod, the commutation copper that circumference uniform distribution is laid Sheet, the top of commutation copper sheet is provided with bonding wire step, and bonding wire groove offered by bonding wire step, by plastics core rod between the sheet of adjacent commutation copper sheet Inject phenolic moulding powder between the sheet between sheet to be dielectrically separated from, it is characterised in that: the top end face of plastics core rod is higher than commutation copper sheet Top end face, between sheet, the top of phenolic moulding powder has top extension upwards, the overhead height of phenolic moulding powder between the sheet after upwardly extending As the top face height of plastics core rod, the top end face of commutation copper sheet is by shape after the top extension isolation of phenolic moulding powder between sheet Become the most independent semi-surrounding space.
After using technique scheme, between sheet, the top of phenolic moulding powder has top extension upwards, then makes bakelite between sheet The overhead height of powder is more than the top face height of commutation copper sheet, and the top end face of such commutation copper sheet will be by phenolic moulding powder between sheet Top extend isolated and formed the most independent semi-surrounding space, even if therefore having glue or welding slag to fall commutation copper sheet Top end face, as there is the isolation that the top of phenolic moulding powder between sheet extends, so prevent between adjacent commutation copper sheet is different Thing contacts, thus reduces unexpected generation.
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, a kind of tank commutator of the present utility model, including plastics core rod 1 with at the cylindrical of plastics core rod 1 Making the commutation copper sheet 2 that circumference uniform distribution is laid, 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, Injected phenolic moulding powder 4 between the sheet between sheet by plastics core rod 1 between the sheet of adjacent commutation copper sheet 2 to be dielectrically separated from, the top of plastics core rod 1 End surface A is higher than the top end face B of commutation copper sheet 2, and between sheet, the top of phenolic moulding powder 4 has top extension upwards, upwardly extends After sheet between the overhead height of phenolic moulding powder 4 as the top end face A height of plastics core rod 1, the top end face quilt of commutation copper sheet 2 Between sheet, the top of phenolic moulding powder 4 forms the most independent semi-surrounding space after extending isolation.
