Abstract
The utility model discloses a collector ring of a generator. The collector ring comprising an insulating support body, a short conductive part, a long conductive part, a first copper ring and a second ring, wherein the short conductive part is fixedly connected with the second copper ring through the insulating support body, the long conductive part passes through the interior of the second copper ring and is connected with the first copper ring, the long conductive part is not in contact with the second copper ring, and an insulating bracket is arranged between the first copper ring and the second copper ring. The generator collector ring solves the problems that the metal powder produced by the friction between the carbon brush and the copper rings accumulates in the groove between two copper rings, thereby easily leading to the short circuit and failure of the products, and causing unnecessary potential safety hazards; and the cost and unnecessary workload are reduced.
Description
Technical field
The utility model relates to a kind of collector ring, especially relates to a kind of collector ring of generator that is applied to automotive field.
Background technology
Collector ring is to be used in anyly when requiring continuous rotation, needs again in the generator system of transmission power supply and signal from the fixed position to the position of rotation.Collector ring can improve systematic function, and simplied system structure is avoided wire to cause in rotary course and sprained.
As shown in Figure 1, traditional collector ring is by insulation support body 1, short-range missile electricity parts 2, long conductive component 3, the first copper ring 4 and the second copper ring 5, described short-range missile electricity parts 2 are fixedly connected with by insulation support body 1 with the second copper ring 5, long conductive component 3 passes in the ring of the second copper ring 5 and is connected with the first copper ring 4, described long conductive component 3 does not contact with the second copper ring 5, and the first copper ring 4 of this collector ring and the second copper ring 5 employings is the disjunctor copper sheathing, to change again instrument processing after its pressure injection over to, then will draw a groove to make the up and down copper ring separately in the middle of the disjunctor copper sheathing.
Adopt the collector ring that this disjunctor copper sheathing is processed into to have following defective: (1) is owing to having drawn a groove to form up and down two copper rings in the middle of will the disjunctor copper sheathing man-hour adding, cause collector ring in the installation course of work, the metal powder that produces that rubs between carbon brush and copper ring can be deposited in the groove of two copper rings, very easily cause the product short-circuit failure, cause unnecessary potential safety hazard; (2) increase cost, increased again unnecessary workload simultaneously.
Summary of the invention
For the deficiencies in the prior art, the utility model discloses a kind of collector ring of generator, the metal powder that having solved rubs between carbon brush and copper ring produces can be deposited in the groove of two copper rings, very easily cause the product short-circuit failure, cause unnecessary potential safety hazard, simultaneously reduce again cost, reduced unnecessary workload.
In order to realize above-mentioned effect, the technical solution adopted in the utility model is: a kind of collector ring of generator, comprise insulation support body, short-range missile electricity parts, long conductive component, the first copper ring and the second copper ring, described short-range missile electricity parts are fixedly connected with by insulation support body with the second copper ring, long conductive component passes in the ring of the second copper ring and is connected with the first copper ring, described long conductive component does not contact with the second copper ring, is provided with insulating support between described the first copper ring and the second copper ring.
Further, described insulating support comprise rack body and between described the first copper ring and the second copper ring the projection insulated part.
Further, the axial length of described insulating support is not more than the axial length summation of the first copper ring and the second copper ring, and is not less than the minimum value of the axial length of the first copper ring and the second copper ring.
Further, the rack body of described insulating support is provided with the structure that matches with short-range missile electricity parts, long conductive component, the first copper ring and the second copper ring.
technique scheme of the present utility model, the effect that reaches is: by between described the first copper ring and the second copper ring, insulating support being set, make between the first copper ring and the second copper ring without groove, just do not have in the generator operation process during metal powder is deposited in intermediate groove, therefore just can not produce the short-circuit failure problem, the qualification rate that has improved product has also extended simultaneously product useful life, and removed and caused unnecessary potential safety hazard because of short circuit, make simultaneously manufacturing procedure reduce, save cost and improved production efficiency, also improved simultaneously the serviceability of product.
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model according to specific embodiment of the utility model also by reference to the accompanying drawings.
