Abstract
The invention discloses Novel commutator, including the commutation copper sheet that the excircle at diverter body is uniformly laid, commutation copper sheet is provided with sheet foot and implants diverter this is internal with diverter body strong bonded, sheet foot is made up of the floor of narrower width and the riser of wider width, it is characterized in that: commutation copper sheet divides commutation copper sheet A and commutation copper sheet B two types, commutation copper sheet A and commutation copper sheet B is laid staggeredly at the excircle of diverter body, the floor of the sheet foot of commutation copper sheet A is less at diverter length dimension in the radial direction, the floor of the sheet foot of commutation copper sheet B is bigger at diverter length dimension in the radial direction, the riser of the riser of the sheet foot of commutation copper sheet A and the sheet foot of commutation copper sheet B staggers non-interference in diverter position in the radial direction mutually. present invention is specifically directed to that radial dimension is less, commutation copper sheet sheet number is more and has the diverter product of high-speed demand and designs, the bond strength between commutation copper sheet and diverter body can be strengthened, improve the mechanical performance of diverter product.
Description
[technical field]
The present invention relates to the improvement of a kind of diverter product invention.
[background technology]
Diverter is used widely in motor, electric tool product, the essential structure of diverter is: include the commutation copper sheet uniformly laid at the excircle of diverter body, described commutation copper sheet is together with diverter body injection-compression molding, and described commutation copper sheet is provided with sheet foot and implants diverter this is internal with diverter body strong bonded. for strengthening the bond strength between commutation copper sheet and diverter body, improve the mechanical performance of diverter product, adopting maximum methods at present is improve the structure of sheet foot and arrange reinforcing ring, and improving the optimal technical scheme of sheet leg structure is then the size adding large stretch of foot. but it is less for radial dimension, the diverter product that commutation copper sheet sheet number is more, the gauge (referring to the size on diverter circumferencial direction) of its sheet foot (sheet foot is made up of the floor of narrower width and the riser of wider width) size particularly its riser portion of sheet foot is severely limited, spacing between its riser of sheet foot of each adjacent commutation copper sheet can be only small, if adding the gauge of wide sheet its riser of foot, so very easily collide when commutation copper sheet is with diverter body pressure injection together between its riser of adjacent sheet foot and contact, thus causing that the diverter product percent defective after injection-compression molding remains high.
[summary of the invention]
For the deficiencies in the prior art, it is an object of the invention to be in that to provide a kind of and be specifically designed for that radial dimension is less, commutation copper sheet sheet number is more and has the product of high-speed demand and designs, the bond strength between commutation copper sheet and diverter body can be strengthened, improve the Novel commutator of product mechanical performance.
For solving above-mentioned technical problem, the present invention has adopted the following technical scheme that:
Novel commutator, including the commutation copper sheet that the excircle at diverter body is uniformly laid, described commutation copper sheet is together with diverter body injection-compression molding, described commutation copper sheet is provided with sheet foot and implants diverter this is internal with diverter body strong bonded, the cross section of described foot is T-shaped, described foot is made up of the floor of narrower width and the riser of wider width, described riser is connected with commutation copper sheet body by floor, it is characterized in that: described commutation copper sheet divides commutation copper sheet A and commutation copper sheet B two types, commutation copper sheet A and commutation copper sheet B is laid staggeredly at the excircle of described diverter body, the floor of the sheet foot of commutation copper sheet A is less at diverter length dimension in the radial direction, the floor of the sheet foot of commutation copper sheet B is bigger at diverter length dimension in the radial direction, the riser of the riser of the sheet foot of commutation copper sheet A and the sheet foot of commutation copper sheet B staggers non-interference in diverter position in the radial direction mutually.
Adopt the diverter of technique scheme, due to adjacent commutation copper sheet the floor of sheet foot different at diverter length dimension in the radial direction, the riser making the sheet foot of adjacent commutation copper sheet staggers mutually in diverter position in the radial direction, then riser both sides just can reserve bigger space to widen the gauge of riser and will not interfere, so not only strengthen the bond strength between commutation copper sheet and diverter body, improve the mechanical performance of diverter product, and avoid colliding when commutation copper sheet is with diverter body pressure injection together and contact, ensure that the quality of diverter product. therefore, the present invention can be suitable for that radial dimension is less, commutation copper sheet sheet number is more and has the diverter product of high-speed demand very well.
As preferably, the centre of described floor offers elongated hole.

[detailed description of the invention]
As shown in the figure, the Novel commutator of the present invention, including the commutation copper sheet that the excircle at diverter body 1 is uniformly laid, described commutation copper sheet is together with diverter body 1 injection-compression molding, described commutation copper sheet is provided with sheet foot and implants in diverter body 1 and diverter body 1 strong bonded, the cross section of described foot is T-shaped, described foot is made up of the floor 2 of narrower width and the riser 3 of wider width, described riser 3 is connected with commutation copper sheet body by floor 2, described commutation copper sheet divides commutation copper sheet A and commutation copper sheet B two types, commutation copper sheet A and commutation copper sheet B is laid staggeredly at the excircle of described diverter body 1, the floor 2 of the sheet foot of commutation copper sheet A is less at diverter length dimension L2 in the radial direction, the floor 2 of the sheet foot of commutation copper sheet B is bigger at diverter length dimension L1 in the radial direction, the riser 3 of the riser 3 of the sheet foot of commutation copper sheet A and the sheet foot of commutation copper sheet B staggers non-interference in diverter position in the radial direction mutually, the gauge b of riser 3 has wider width than tradition, the centre of described floor 2 offers elongated hole 4.
Above-mentioned diverter product, due to adjacent commutation copper sheet the floor of sheet foot different at diverter length dimension in the radial direction, the riser making the sheet foot of adjacent commutation copper sheet staggers mutually in diverter position in the radial direction, then riser both sides just can reserve bigger space to widen the gauge of riser, so not only strengthen the bond strength between commutation copper sheet and diverter body, improve the mechanical performance of diverter product, and avoid colliding when commutation copper sheet is with diverter body pressure injection together and contact, ensure that the quality of diverter product. therefore, the present invention can be suitable for that radial dimension is less, commutation copper sheet sheet number is more and has the diverter product of high-speed demand very well.
