Abstract
The invention discloses tank commutators, make more commutation copper sheets of circumference uniform distribution including phenolic moulding powder matrix and in the outer circle of phenolic moulding powder matrix, it is dielectrically separated between adjacent commutation copper sheet by mica sheet, the top of commutation copper sheet is equipped with bonding wire step, bonding wire step opens up bonding wire slot, the medial surface of commutation copper sheet is equipped with fixed feet and is implanted in phenolic moulding powder matrix, it is characterized by: every commutation copper sheet is made of the left and right halfbody of intermediate split same shape, the mutual abutting contact of left and right halfbody, the fixed feet have laying in the medial surface of left and right halfbody.The present invention solve prior art commutation copper sheet due to angle of circumference is big and can not from the side punching fixed feet the technical issues of, while efficiently solve the problems, such as commutation copper sheet as circumferential size is big, work when thermal deformation it is big and caused by operating noise it is big.
Description
Technical field
The present invention relates to a kind of improvement of tank commutator inventions.
Background technique
The tank commutator of the prior art makees the more of circumference uniform distribution including phenolic moulding powder matrix and in the outer circle of phenolic moulding powder matrix
The medial surface of commutation copper sheet, commutation copper sheet is equipped with fixed feet, and commutation copper sheet is drawn out by copper wires transversal first at the time of molding
Then face shape carries out punching from the side, fixed feet is formed simultaneously during punching.When opening up two on a commutation copper sheet
When bonding wire slot, the piece number of commutation copper sheet can be smaller and angle of circumference will be larger, and the increase of angle of circumference can make the two of commutation copper sheet
The part punching path of fixed feet is blocked on the inside of flank, therefore influences the formation of fixed feet, unless changing the punching of fixed feet
Size or the thickness for changing two flank of commutation copper sheet, this obviously will affect the working performance of tank commutator, and undesirable.Separately
Outside, often circumferential size is big for the big commutation copper sheet of angle of circumference, and thermal deformation is also big when work, the circumference for contacting commutator with carbon brush
Surface is not round and smooth, and it is big to will cause operating noise.
Summary of the invention
In view of the deficiencies in the prior art, the object of the present invention is to provide a kind of solution prior art commutation copper sheets due to circumference
Angle it is big and can not punching fixed feet technical problem from the side, while also solving commutation copper sheet since circumferential size is big, work
When thermal deformation it is big and cause the tank commutator of the big problem of operating noise.
The present invention adopts the following technical scheme that complete:
Tank commutator makees more commutation copper sheets of circumference uniform distribution, phase including phenolic moulding powder matrix and in the outer circle of phenolic moulding powder matrix
It is dielectrically separated between adjacent commutation copper sheet by mica sheet, the top of commutation copper sheet is equipped with bonding wire step, and bonding wire step opens up weldering
Wire casing, the medial surface of commutation copper sheet are equipped with fixed feet and are implanted in phenolic moulding powder matrix, it is characterised in that: every commutation copper sheet is in
Between split same shape left and right halfbody composition, the mutual abutting contact of left and right halfbody, the fixed feet is in the halfbody of left and right
There is laying in side.
The upper and lower ends of the fixed feet, which are equipped with, reinforces annular groove, reinforces and places reinforcing ring in annular groove.
The tank commutator of above-mentioned technical proposal is innovated it is critical that one of inherently larger angle of circumference is changed
To copper sheet from the intermediate split left and right halfbody for becoming identical size, the angle of circumference for being equivalent to original commutation copper sheet in this way halves,
Again by being respectively equipped with fixed feet in the medial surface of left and right halfbody, so fixation would not be blocked on the inside of two flanks of commutation copper sheet
The punching path of foot, and then commutation copper sheet can be made to be formed simultaneously fixed feet during punching, solve prior art commutation
Copper sheet due to angle of circumference is big and can not from the side punching fixed feet the technical issues of；Simultaneously through above-mentioned design, work as fixed feet
Upper and lower ends be equipped with when reinforcing annular groove, the punching for reinforcing annular groove will not be influenced, if by original design, commutation copper sheet
The part punching path for reinforcing annular groove can be equally blocked on the inside of two flanks, unless changing the size for reinforcing annular groove, it is clear that this is also
It is worthless.In addition, the circumferential size due to commutation copper sheet becomes smaller, thermal deformation is also small when work, and commutator is contacted with carbon brush
Circumferential surface can be rounder and more smooth, reduces the generation of operating noise.
Detailed description of the invention
The present invention has following attached drawing:
Fig. 1 is top-direction view of the invention,
Fig. 2 is the B-B cross-sectional view of Fig. 1,
Fig. 3 is the enlarged drawing of commutation copper sheet in Fig. 1,
Fig. 4 is the structure chart of prior art commutation copper sheet.
Specific embodiment
As shown in Figure 1-3, tank commutator of the invention, makees including phenolic moulding powder matrix 1 and in the outer circle of phenolic moulding powder matrix 1
13 commutation copper sheets 2 of circumference uniform distribution are dielectrically separated between adjacent commutation copper sheet 2, every commutation copper sheet by mica sheet 3
2 are made of the left and right halfbody 21 of the same shape of intermediate split (to the A that bursts at the seams), the mutual abutting contact of left and right halfbody 21, and commutate copper
The top of piece 2 is equipped with bonding wire step 7, and left and right halfbody 21 respectively opens up a bonding wire slot 4 in bonding wire stepped locations, commutation copper sheet 2
Medial surface is equipped with fixed feet 5 and is implanted in phenolic moulding powder matrix, and the fixed feet 5 has laying in the medial surface of left and right halfbody 21,
The upper and lower ends of the fixed feet 5, which are equipped with, reinforces annular groove 8, reinforces and places reinforcing ring 6 in annular groove 8.
Fig. 4 show the tank commutator commutation copper sheet of the prior art, hence it is evident that as it can be seen that working as from the side side of commutation copper sheet 10
When carrying out punching to (arrow direction), (position 11) can block the part punching of fixed feet 12 on the inside of two flanks of commutation copper sheet 10
Path, make fixed feet 12 can not punching formed.
