Abstract
The utility model discloses a kind of Novel commutator, comprise matrix, commutator segment and insulating trip, commutator segment comprises commutator segment body and stretches into the dove-tail form root in matrix, on dove-tail form root, longitudinal arrangement has multiple through hole, the upper surface that insulating trip is combined with matrix is provided with dovetail groove, and the bottom that insulating trip is combined with matrix is provided with dovetail.In the utility model, stretch into longitudinal arrangement on the dove-tail form root in matrix and have multiple through hole, adhesion between commutator segment and matrix is enhanced, effectively prevent commutator segment float or fly out when commutator high-speed rotates, in addition, the upper surface that insulating trip is combined with matrix is provided with dovetail groove, and the bottom that insulating trip is combined with matrix is provided with dovetail, adhesion between insulating trip and matrix is strengthened, effectively prevents when commutator high-speed rotates insulating trip float or fly out.
Description
Technical field
The utility model relates to a kind of Novel commutator.
Background technology
Commutator is widely used in electromechanics trade, commutator mainly contains end commutator, tank commutator and hook-type commutator, mechanical strength and the hypervelocity performance of commutator are relevant with the intensity of commutator segment own, simultaneously with commutator when injection mo(u)lding commutator segment, adhesion between matrix has great relation, the shortcoming that tradition commutator exists has: the adhesion between commutator segment and matrix is more weak, when commutator high-speed rotates, commutator segment easily floats or flies out, in addition, adhesion between insulating trip and matrix is also more weak, so insulating trip also easily floats when rotating with commutator high-speed or flies out.
Summary of the invention
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide a kind of commutator segment, insulating trip is combined more firmly Novel commutator with matrix.
For this reason, the Novel commutator that the utility model provides comprises matrix, commutator segment and insulating trip, commutator segment comprises commutator segment body and stretches into the dove-tail form root in matrix, on dove-tail form root, longitudinal arrangement has multiple through hole, the upper surface that insulating trip is combined with matrix is provided with dovetail groove, and the bottom that insulating trip is combined with matrix is provided with dovetail.
In the utility model, stretch into longitudinal arrangement on the dove-tail form root in matrix and have multiple through hole, adhesion between commutator segment and matrix is enhanced, effectively prevent commutator segment float or fly out when commutator high-speed rotates, in addition, the upper surface that insulating trip is combined with matrix is provided with dovetail groove, and the bottom that insulating trip is combined with matrix is provided with dovetail, adhesion between insulating trip and matrix is strengthened, effectively prevents when commutator high-speed rotates insulating trip float or fly out.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the Novel commutator that the utility model provides comprises matrix 1, commutator segment and insulating trip 2, the dove-tail form root 4 that commutator segment comprises commutator segment body 3 and stretches in matrix 1, on dove-tail form root 4, longitudinal arrangement has multiple through hole 5, insulating trip 2 is provided with dovetail groove 6 with the upper surface that matrix 1 is combined, and insulating trip 2 is provided with dovetail 7 with the bottom that matrix 1 is combined.
In the present embodiment, stretch into longitudinal arrangement on the dove-tail form root 4 in matrix 1 and have multiple through hole 2, adhesion between commutator segment and matrix 1 is enhanced, effectively prevent commutator segment float or fly out when commutator high-speed rotates, in addition, insulating trip 2 is provided with dovetail groove 6 with the upper surface that matrix 1 is combined, insulating trip 2 is provided with dovetail 7 with the bottom that matrix 1 is combined, adhesion between insulating trip 2 and matrix 1 is strengthened, effectively prevents when commutator high-speed rotates insulating trip 2 float or fly out.
