Description

平面碳换向器 技术领域 本实用新型涉及一种电机上使用的换向器，具体地说是涉及一种牢 固型平面 ^炭换向器。 背景技术 现有的平面碳换向器， 包括换向片、模塑料、碳块， 换向片的本体 与该换向器的旋转轴线相垂直,碳块设在换向片的本体的夕卜表面上并整 体盖住换向片，碳块的外周围无任何包围的保护层（如图 4、图 5所示）。 该换向器在制造过程中，需要对其半成品进行机加工,此时碳块的周围 由于直接受力而易遭受损坏，从而影响了产品的技术性能。 同时， 影响 了产品的成品率，又因为碳块的成本比其它材料高，还增加了产品的生 产成本。 实用新型内容 本实用新型的目的在于克服上述的不足，而提供一种其半成品在机 加工时碳块外周围不会受到损坏的牢固型平面碳换向器。  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a commutator for use on a motor, and more particularly to a solid planar carbon commutator. BACKGROUND OF THE INVENTION A conventional planar carbon commutator includes a commutator segment, a molding compound, and a carbon block. The body of the commutator segment is perpendicular to the rotation axis of the commutator, and the carbon block is disposed on the body of the commutator segment. The commutator segments are covered on the surface and the outer layer of the carbon block is not surrounded by any protective layer (as shown in Figs. 4 and 5). In the manufacturing process, the commutator needs to machine its semi-finished products, and the surrounding of the carbon block is easily damaged due to direct force, thereby affecting the technical performance of the product. At the same time, it affects the yield of the product, and because the cost of the carbon block is higher than other materials, it also increases the production cost of the product. SUMMARY OF THE INVENTION The object of the present invention is to overcome the above-mentioned deficiencies and to provide a solid planar carbon commutator in which the semi-finished product is not damaged around the carbon block during machining.
为实用上述目的，本实用新型的解决方案是：一种牢固型平面破换 向器， 包括换向片、模塑料、碳块， 在所述的碳块的外周围联有包围保 护层。  In order to utilise the above object, the solution of the present invention is: a solid planar breakage commutator comprising a commutator segment, a molding compound, a carbon block, and an enclosing protective layer joined to the outer periphery of the carbon block.
所述的包围保护层为塑料包围保护层。  The surrounding protective layer is a plastic surrounding protective layer.
所述的包围保护层为铜片包围保护层。  The surrounding protective layer is a copper sheet surrounding the protective layer.
采用本实用新型结构后， 由于包围保护层对碳块的保护作用，使平 面碳换向器半成品在机加工时碳块不会受到外力而损伤。 因此，本实用 新型与现有技术相比，提高了产品的成品率， 降低了生产成本，提升了 产品的技术性能。 同时，增加了碳块与换向片的结合牢固度，使产品在 电机高速运转中工作性能稳定可靠。 附图说明 下面结合附图与实施方式对本实用新型作进一步的详细描述。 图 1为本实用新型牢固型平面碳换向器的结构示意图; After adopting the structure of the utility model, the carbon block is protected from the carbon block by the surrounding protective layer, so that the carbon block of the planar carbon commutator semi-finished product is not damaged by external force during machining. Therefore, compared with the prior art, the utility model improves the yield of the product, reduces the production cost, and improves the technical performance of the product. At the same time, the combination of carbon block and commutator is strengthened, which makes the product stable and reliable in high-speed operation of the motor.
