Abstract
The utility model discloses high heat dispersion commutator, including commutation matrix and the cylindrical commutation copper sheet for making circumference arrangement in commutation matrix, it is characterised in that：In the interlude of the whole height of commutator, commutation matrix is emptied, the insulating voids reserved between adjacent commutation copper sheet make commutator is interior to be in a circumferential direction interlinked to the outside, the top of commutator is cylindrical to be provided with upper reinforcing ring, the bottom cylindrical of commutator is provided with lower reinforcing ring, and upper and lower reinforcing ring banding is outside commutation copper sheet.The utility model is in light weight, perfect heat-dissipating, and firm beneficial to bonding wire.
Description
Technical field
It the utility model is related to a kind of improvement invention of commutator.
Background technology
The commutator of prior art, including commutation matrix and the cylindrical commutation copper sheet for making circumference arrangement in commutation matrix,
The medial surface of commutation copper sheet will set in hook implantation commutation matrix and be combined with commutation matrix to ensure the mechanical strength of commutator,
Commutation matrix solid design is wanted in addition to endoporus, weight weight, heat dispersion is poor, in addition, the bonding wire crotch of commutation copper sheet with line
It when enclosing wire progress bonding wire connection, due to crotch insufficient strength and cannot support, therefore easily deform backward, rosin joint occur
Or bonding wire loosely phenomena such as.
The content of the invention
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of in light weight, perfect heat-dissipating, and is beneficial to
The firm high heat dispersion commutator of bonding wire.
The utility model is adopted the following technical scheme that to complete：
High heat dispersion commutator, including commutation matrix and the cylindrical commutation copper sheet for making circumference arrangement in commutation matrix,
It is characterized in that：In the interlude of the whole height of commutator, commutation matrix is emptied, and what is reserved between adjacent commutation copper sheet is exhausted
Edge space makes commutator is interior to be in a circumferential direction interlinked to the outside, and the top of commutator is cylindrical to be provided with upper reinforcing ring, the bottom of commutator
Cylindrical to be provided with lower reinforcing ring, upper and lower reinforcing ring banding is outside commutation copper sheet.
Using the high heat dispersion commutator of above-mentioned technical proposal, in the interlude commutation matrix quilt of the whole height of commutator
Empty, commutator weight can be mitigated significantly, while the insulating voids reserved between adjacent commutation copper sheet make commutator in circumference side
It is interlinked to the outside in upwards, so perfect heat-dissipating, meanwhile, upper outer annular-stiffer can also be from the medial surface pair of commutation copper sheet bonding wire crotch
Bonding wire crotch, which is formed, to be supported, so commutator, when progress bonding wire is connected between coil after being installed on motor, bonding wire crotch is just
Situations such as being not easy excessive deformation backward, avoiding rosin joint, bonding wire loosely occurs.
Preferably, circular arc or chamfered transition are provided between the left and right side of commutation copper sheet and medial surface.Set by above-mentioned
Meter, first, the weight of commutation copper sheet can be mitigated, second, can increase the adjacent commutation of position at the top and bottom of the whole height of commutator
The intensity of commutation matrix between copper sheet.
Brief description of the drawings
The utility model has drawings described below：
Fig. 1 is the top-direction view of high heat dispersion commutator,
Fig. 2 is Fig. 1 A-A views.
Embodiment
As illustrated, high heat dispersion commutator of the present utility model, including commutation matrix 1 and in the outer of commutation matrix 1
Circle makees the commutation copper sheet 3 of circumference arrangement, and commutation copper sheet 3 is provided with 22, and the top of commutation copper sheet 3 carries crotch 2, is commutating
The interlude of the whole height of device, commutation matrix 1 are emptied to form commutator internal cavities 6, reserved between adjacent commutation copper sheet 3
Insulating voids make commutator is interior to be in a circumferential direction interlinked to the outside, the top of commutator is cylindrical to be provided with upper reinforcing ring 4, commutator
Bottom cylindrical is provided with lower reinforcing ring 7, and upper and lower reinforcing ring banding is outside commutation copper sheet 3, the left and right side of commutation copper sheet 3 and medial surface
Between be provided with circular arc 5 or chamfered transition.
Claims (2)
