Abstract
The utility model discloses a high-strength plane carbon commutator, comprising a copper skeleton, carbon plates, and a phenolic resin matrix. The carbon plates are adhered on a lower end face of the copper skeleton. The commutator is characterized in that excircle diameter of the carbon plate is smaller than excircle diameter of the commutator. The excircle diameter of the carbon plate is wrapped by the phenolic resin matrix. The lower end face of the copper skeleton is provided with hooked pins embedded into the carbon plates. Height of the top of a bonding wire hook on the copper skeleton is consistent with height of an upper end face of the phenolic resin matrix. The back side of the bonding wire hook is abutted against the phenolic resin matrix. The commutator is advantaged by high mechanical strength, firm carbon plate combination, low carbon plate resistance, and high bonding wire hook strength.
Description
Technical field
The utility model relates to a kind of improvement invention of flat carbon commutator.
Background technology
In recent years, along with the development of commutator technology, flat carbon commutator comes into the market gradually, but also there are various quality problems in flat carbon commutator, wherein modal have following some: 1. mechanical strength is inadequate, the combination of carbon plate and commutator other parts is firm not, and carbon plate easily departs from or occur side direction and longitudinally loosening; 2. the insufficient strength of bonding wire crotch, in the time of spot welding bonding wire, bonding wire crotch is easily out of shape and causes rosin joint backward; 3 carbon plate resistance are larger, can consume more power supply, simultaneously anticorrosive anti-wear poor-performing.
Summary of the invention
In view of the deficiencies in the prior art, the technical problems to be solved in the utility model is to be to provide the High Strength Plane carbon commutator that a kind of mechanical strength is high, carbon plate combination is firm, carbon plate resistance is little and bonding wire crotch intensity is high.
The utility model takes following technical scheme to complete:
High Strength Plane carbon commutator, comprise copper skeleton, carbon plate and phenolic resin as matrix resin, carbon plate is sticked in the lower surface of copper skeleton, it is characterized in that: the outside diameter of carbon plate is less than the outside diameter of commutator, and the cylindrical of carbon plate is wrapped up by described phenolic resin as matrix resin.The inside that the lower surface of copper skeleton is provided with hook pin implants carbon plate.The overhead height of the bonding wire crotch on copper skeleton and the upper surface height of phenolic resin as matrix resin maintain an equal level, and the back side of bonding wire crotch is against phenolic resin as matrix resin.Carbon plate adopts graphite fluoride composite material.
The High Strength Plane carbon commutator that adopts technique scheme, useful technique effect is: 1. the cylindrical of carbon plate is wrapped up by described phenolic resin as matrix resin, can improve the bond strength of carbon plate and phenolic resin as matrix resin, thereby makes the mechanical strength of commutator high; 2. the lower surface of copper skeleton is provided with the inside of hook pin implantation carbon plate, can improve the bond strength of carbon plate and copper skeleton, thereby make the mechanical strength of commutator high; 3. the back side of bonding wire crotch is against phenolic resin as matrix resin, improve the intensity of bonding wire crotch, so bonding wire crotch just can not be out of shape backward in the time of spot welding bonding wire, avoid rosin joint etc. be unfavorable for commutator bonding wire firmly situation occur, improve work quality and the useful life of commutator; 4. carbon plate adopts graphite fluoride composite material, and the resistance of carbon plate is little, improves intensity, and anticorrosive anti-wear.
Accompanying drawing explanation
The utility model has the following drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in the figure, High Strength Plane carbon commutator of the present utility model, comprise copper skeleton 3, carbon plate 4 and phenolic resin as matrix resin 1, carbon plate 4 is sticked in the lower surface of copper skeleton 3, carbon plate 4 adopts graphite fluoride composite material, this composite material for adding carbon fibre material in fluorographite, the outside diameter of carbon plate 4 is less than the outside diameter of commutator, the cylindrical of carbon plate 4 is wrapped up by phenolic resins 6 parts of described phenolic resin as matrix resin 1, the inside that the lower surface of copper skeleton 3 is provided with hook pin 5 implants carbon plate 4, the overhead height of the bonding wire crotch 2 on copper skeleton 3 and the upper surface height of phenolic resin as matrix resin 1 maintain an equal level, the back side of bonding wire crotch 2 is against phenolic resin as matrix resin 1.
