Abstract
The invention discloses a carbon deposition and false soldering prevention commutator, which comprises a base body and commutator segments uniformly distributed on the outer circumference of the base body, wherein an insulating groove is arranged between every two adjacent commutator segments for insulation, and a welding wire hook is arranged at the top of each commutator segment, and the commutator is characterized in that: the inner side end of the insulation groove is provided with an axial through groove, and the axial through groove and the insulation groove are arranged in the same direction and penetrate through the upper end face and the lower end face of the base body. The invention can solve the problems of carbon deposition and insufficient soldering of the commutator, thereby eliminating two main factors of motor damage, greatly improving and effectively ensuring the service life of the motor and having low production cost.
Description
Technical field
The present invention relates to a kind of commutator.
Background technology
The damage of motor under normal circumstances has two big main factors, first, the insulation tank carbon distribution of commutator, causes to commutate
Motor damage caused by device short circuit；Second, deposited between the bonding wire crotch of commutator and the enamel-covered wire of motor-spin-coil in a postwelding
In rosin joint, cause motor damage caused by open circuit.Its basic reason is all because commutator has certain deficiency in structure
Formed.
The commutator of prior art, including matrix and the commutator segment uniformly arranged in matrix excircle, adjacent commutator segment it
Between by being insulated provided with insulation tank, the top of commutator segment is provided with bonding wire crotch.Because the groove width of insulation tank is typically strict
Control is within 0.5mm, and depth is limited, i.e., the narrow space ventilation condition extreme difference of insulation tank, insulation tank have dead angle, institute
Carbon dust caused by carbon brush abrasion inevitably accumulates in insulation tank and is not easy to discharge when being worked with motor, even if using
Blowing mode is also to have little effect；When carbon dust is stored to a certain degree in insulation tank inner product, just it is likely to that commutator occurs
Short circuit phenomenon.In addition, the top of every commutator segment only sets a bonding wire crotch, so when a commutator segment and two enamel-covered wires
When carrying out spot welding, because two enamel-covered wires will be arranged above and below, so enough length can just be encased firstly the need of the length of bonding wire crotch
Two enamel-covered wires, the semicircle that connects of two enamel-covered wires can not all contact with the medial surface of bonding wire crotch up and down in addition, so influenceing
Simultaneously easily there is rosin joint phenomenon in spot welding stability.
The content of the invention
In view of the deficiency of background technology, the purpose of the present invention, which aims to provide one kind, can thoroughly solve carbon distribution and problem of faulty soldering,
So as to eliminate the two of motor damage big main factors, greatly improve and motor service life is effectively ensured, and production cost
The anti-rosin joint commutator of low anti-carbon deposition.
The present invention is adopted the following technical scheme that to complete
The anti-rosin joint commutator of anti-carbon deposition, including matrix and the commutator segment uniformly arranged in matrix excircle, between adjacent commutator segment
Insulated provided with insulation tank, the top of commutator segment is provided with bonding wire crotch, it is characterised in that：The medial extremity of insulation tank is provided with axially
Groove, axial pass trough setting equidirectional with insulation tank simultaneously penetrate the upper and lower end face of matrix.
The axial pass trough designs for circular hole, and the aperture of axial pass trough is not less than 4mm.
Commutator segment has double hook design, and the top of every commutator segment is provided with two bonding wire crotches, and two bonding wire crotches edges are changed
Be arranged side by side to piece circumferencial direction and mutually at a distance from.
After adopting the above technical scheme, the present invention has advantages below：1. the medial extremity of insulation tank is provided with axial pass trough,
The ventilation condition of insulation tank can greatly be improved, dead angle, and the motor internal when motor runs at high speed is not present in insulation tank
Disengaging can be forced from the both ends of axial pass trough by disturbing air, so carbon dust caused by carbon brush abrasion is difficult in insulation tank inner product
Deposit, so as to thoroughly solve the problems, such as commutator carbon distribution.2. commutator segment has double hook design, so, when a commutator segment will be with
When two enamel-covered wires carry out spot welding, two enamel-covered wires can correspond with two bonding wire crotches carries out spot welding, increases enamel-covered wire
With the contact area of bonding wire crotch medial surface, spot welding stability is improved to avoid the occurrence of rosin joint phenomenon；Meanwhile the length of bonding wire crotch
Degree can shorten, i.e. the length of commutator segment before the forming can shorten, and save material, reduce production cost.

Within, the medial extremity of insulation tank 4 is provided with axial pass trough 5, and the setting equidirectional with insulation tank 4 of axial pass trough 5 simultaneously penetrates the upper of matrix 1
Lower surface, the axial pass trough 5 design for circular hole, and the aperture of axial pass trough 5 is not less than 4mm.Commutator segment 2 designs with double hook,
The top of every commutator segment 2 is provided with two bonding wire crotches 3, and two bonding wire crotches 3 are arranged side by side along the circumferencial direction of commutator segment 2 and phase
Mutually at a distance from.
