Description
[technical field]
This utility model relates to commutator topology field, is specifically related to a kind of tank commutator.
[background technology]
Diverter is generally divided into Hooked reverser, tank commutator and end commutator three kinds, traditional tank commutator,
For strengthening the bond strength between grooved commutation copper sheet and phenolic moulding powder matrix, promote the mechanical performance of tank commutator product and surpass
Speed performance, often uses the structure of band reinforcing ring inside tank commutator, for avoiding conducting electricity between sheet, and reinforcing ring insulation to be used material
Material, the most substantially uses glass fiber material, and the resistance to elevated temperatures of the reinforcing ring of glass fiber material is bad, high temperature
Time be easily deformed, so when tank commutator runs up, due to high temperature, section between the external diameter change of tank commutator and sheet
Difference is relatively big, has a strong impact on functional reliability and the service life of tank commutator, and the cost of the reinforcing ring of fibrous material is also simultaneously
Of a relatively high.
[summary of the invention]
In view of the deficiency of background technology, the purpose of this utility model aims to provide that a kind of resistance to elevated temperatures is good, runs up
Time external diameter change and sheet between section difference little, improve functional reliability and service life, the tank commutator of low cost simultaneously.
This utility model has adopted the following technical scheme that:
Tank commutator, including phenolic moulding powder matrix and the grooved commutation copper of the uniform screening of excircle at phenolic moulding powder matrix
Sheet, the top of grooved commutation copper sheet is provided with bonding wire step, and the upper and lower end face of grooved commutation copper sheet is provided with reinforcement annular groove, adjacent grooved
It is dielectrically separated from by mica sheet between commutation copper sheet, it is characterised in that: the reinforcing ring arranged in strengthening annular groove is by surrounding one
Multiple ceramic beads composition of circle, between multiple ceramic beads mutually at a distance from, the quantity of ceramic bead and grooved commutation copper sheet
Quantity identical, ceramic bead intert is located in the middle of adjacent grooved commutation copper sheet, the both sides of ceramic bead with strengthen annular groove lateral slot
Mouth offsets contact, strengthens the top of annular groove and is provided with Pressing Deformation and is fixed tightly in by ceramic bead and strengthens in annular groove.
In technique scheme, the multiple ceramic bead of tank commutator inner utilization forms a circle and forms reinforcing ring structure.
First grooved commutation copper sheet carries out screening, and the reinforcing ring groove location of the grooved commutation copper sheet after screening puts into ceramic bead, ceramic bead
After putting into, its two sides can abut against tactile with the lateral notch strengthening annular groove, after the top strengthening annular groove carries out Pressing Deformation just
Ceramic bead is fixed tightly in reinforcement annular groove, makes formation between ceramic bead with grooved commutation copper sheet be connected the most overall, Qi Zhongtao
Porcelain bead plays the effect of reinforcing ring, and finally after injecting phenolic moulding powder, grooved commutation copper sheet, ceramic bead are closely tied with phenolic moulding powder matrix
Closing, tank commutator completes.Owing to pottery has more preferable high temperature resistant advantage than glass fibre, ceramic bead forms a circle institute's shape
The reinforcing ring become is unlikely to deform, so tank commutator can be made when running up, is not affected by high temperatures, outside tank commutator
Between footpath change and sheet, section difference is less, thus is effectively improved functional reliability and the service life of tank commutator product.Due to pottery
The cost of porcelain bead is the lowest, so that make tank commutator there is lower cost.
[accompanying drawing explanation]
This utility model has a drawings described below:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the A-A sectional view of Fig. 1.
[detailed description of the invention]
As it can be seen, tank commutator of the present utility model, including phenolic moulding powder matrix 1 with at the cylindrical of phenolic moulding powder matrix 1
The grooved commutation copper sheet 4 of week uniformly screening, the top of grooved commutation copper sheet 4 is provided with bonding wire step, grooved commutation copper sheet 4 upper and lower
End face is provided with reinforcement annular groove 5, is dielectrically separated from by mica sheet 6 between adjacent grooved commutation copper sheet 4, sets in strengthening annular groove 5
The reinforcing ring put is made up of the multiple ceramic beads 3 formed a circle, mutually at a distance from, ceramic bead 3 between multiple ceramic beads 3
Quantity identical with the quantity of grooved commutation copper sheet 4, ceramic bead 3 interts and is located in the middle of adjacent grooved commutation copper sheet 4, ceramic bead 3
Both sides abut against tactile with the lateral notch strengthening annular groove 5, the top strengthening annular groove 5 is provided with Pressing Deformation 2 and is fastened by ceramic bead 3
Strengthening in annular groove 5, described Pressing Deformation 2 is by strengthening the top of inner side cell wall of annular groove 5 to strengthening annular groove 5 direction bending institute shape
Become.
Above-mentioned tank commutator, first grooved commutation copper sheet carry out screening in screening plastic sheath and form a circle, then
Reinforcing ring groove location at grooved commutation copper sheet puts into ceramic bead, ceramic bead put into after its two sides can with strengthen annular groove lateral
Notch offsets contact, after ceramic bead is all put into, the top strengthening annular groove inner side slot wall is carried out punching press and is allowed to deform, then
Just ceramic bead is fixed tightly in reinforcement annular groove, makes formation between ceramic bead with grooved commutation copper sheet be connected the most overall, surround
The ceramic bead of one circle plays the effect of reinforcing ring, finally after injecting phenolic moulding powder, and grooved commutation copper sheet, ceramic bead and phenolic moulding powder base
Body is combined closely, and tank commutator completes.Owing to ceramic bead is high temperature resistant, so tank commutator can be made when running up
Being not affected by high temperatures, between the external diameter change of tank commutator and sheet, section difference is less, thus is effectively improved tank commutator product
Functional reliability and service life.
