Abstract
The utility model discloses no-welding carbon commutator copper sheets, it is characterized by: being composed of copper piece and carbon part, carbon part has the appearance profile of copper segment, the inner surface of carbon part is equipped with fixed feet, fixed feet is structure as a whole with carbon part, and the copper piece is fixedly linked with carbon part, and copper piece is from top to bottom through the centre of the carbon part, the upper end of copper piece exposes to carbon part, and the upper end of copper piece carries out the bonding wire crotch for being bent to form commutator.The utility model solves the problems, such as that the commutator segment of carbon commutator needs two sections of welding, guarantees commutator segment integral strength and energy conservation and environmental protection.
Description
Technical field:
The utility model relates to a kind of commutators, and in particular to a kind of commutation copper sheet of carbon commutator.
Background technique:
Commutator is mainly used on various motors, the motor of fuel pump, due to using under fuel oil environment, and in fuel oil
The surface of the copper commutator segment of commutator can inevitably be made added with alcohols materials, these alcohols materials such as some ethyl alcohol
At corrosion, so seriously affecting the service life of fuel oil pump motor.Currently, carbon commutator is mainly used in flat commutator, put down
Face carbon commutator, carbon plate will be brazed on the commutation copper sheet for being fixed on welding crotch, since contact area is big, so can protect
Bonding strength is demonstrate,proved, but for the Hooked reverser for carrying out Cylindrical Surfaces Contact with carbon brush for electric machine, the sectional dimension of commutator segment is small,
Carbon plate is directly the lower section of commutator segment, and so, the contact area between carbon plate and welding crotch can be smaller, it is difficult to guarantee to connect
Intensity is connect, so carbon commutator is rarely applied to the Hooked reverser of periphery, unless carrying out complicated design.
Summary of the invention:
In view of the deficiencies of the prior art, the purpose of the utility model is to provide a kind of commutator segments for solving carbon commutator to need
The problem of wanting two sections of welding guarantees commutator segment integral strength and energy-saving and environment-friendly no-welding carbon commutator copper sheet.
The utility model adopts the following technical scheme that complete:
No-welding carbon commutator copper sheet, it is characterised in that: be composed of copper piece and carbon part, carbon part has copper segment
Appearance profile, the inner surface of carbon part is equipped with fixed feet, and fixed feet is structure as a whole with carbon part, and the copper piece is fixed with carbon part
It is connected, for copper piece from top to bottom through the centre of the carbon part, the upper end of copper piece exposes to carbon part, and the upper end of copper piece is bent
Form the bonding wire crotch of commutator.
The carbon commutator copper sheet of above-mentioned technical proposal, is composed of copper piece and carbon part, and carbon part has copper segment
Appearance profile, carbon part form jail when commutator is formed by the fixed feet that its inner surface is equipped between the matrix of commutator
Consolidation is closed, and the copper piece of bonding wire crotch is arranged from top to bottom through the centre of the carbon part, and being not required to welding can be realized copper piece
Being fixedly linked between carbon part, and then guarantee the integral strength of carbon commutator copper sheet and reach energy-saving and environment-friendly effect.
To guarantee there are enough bond strengths between carbon commutator copper sheet and phenolic moulding powder matrix, preferably, the fixation
Foot is I-shaped.
Preferably, the length of the fixed feet is less than the height of carbon part.
Preferably, the lower end of the copper piece also exposes to carbon part.By above-mentioned design, copper piece is when commutator forms
Dotted fixation, the mechanical strength of Lai Tigao commutator can be formed between the matrix of commutator.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model,
Fig. 2 is the overlook direction figure of Fig. 1.
Specific embodiment:
As shown, the no-welding carbon commutator copper sheet of the utility model, is composed of, carbon part 1 copper piece 2 and carbon part 1
Appearance profile with copper segment, carbon part 1 use graphite fluoride composite material, and the inner surface of carbon part 1 is equipped with I-shaped
Fixed feet 3, the length of fixed feet 3 is less than the height of carbon part 1, and fixed feet 3 is structure as a whole with carbon part 1, the copper piece 2 and carbon
Part 1 is fixedly linked, and can be implanted into copper piece 2 in compression molding by carbon part 1;Copper piece 2 is from top to bottom through in the carbon part 1
Between, the upper end of copper piece 2 exposes to carbon part 1, and the upper end of copper piece 2 carries out the bonding wire crotch 4 for being bent to form commutator, under copper piece 2
End also exposes to carbon part 1, dotted fixation can be formed between the matrix of commutator in commutator molding, to improve commutation
The mechanical strength of device.
