Description
Technical field
It the utility model is related to a kind of commutator.
Background technology
Commutator is mainly used for electromechanics trade, and commutator is divided into plane commutator, tank commutator and hook-type commutator,
It mainly by insulating body and is arranged in base circumferential face upper body, insulation grass is set between adjacent commutator segment and will be by each commutation
Piece separation insulation, commutator segment one end dogleg section are used for wiring.The connection mode of existing commutator segment and matrix is to pass through commutation
The connection wing of on piece is embedded in matrix in injection and realizes, since the volume contact area of the connection wing and matrix is small, causes commutator
Rotate in operation process and acted on by centrifugal force, commutator segment situation separated with matrix, while existing commutator easily occurs
Temperature is excessive during running at high speed easily burns out commutator, or even causes fire and injures and deaths, and there are security risk.
Utility model content
A kind of commutator is provided for insufficient the utility model of background technology, and overcomes above deficiency.
Technical solution is used by the utility model：A kind of commutator, including matrix and commutator segment, described matrix center
Place is equipped with through hole, and the commutator segment back is equipped with the connection wing, and commutator segment is fastened in matrix by connecting the wing, one
Commutator segment connects two connection wings, this two connection wings are connected with the connection wing of adjacent commutator segment；One end connection of commutator segment is set
There is wiring hook, concaveconvex structure is distributed with the upper and lower surface of the connection wing, insulation tank, institute are equipped between the adjacent commutator segment
State insulation tank and be equipped with insulator close to the end in wiring hook direction to be interior, temperature inductor is equipped with described matrix.
The connection wing is connected with commutator segment junction by leading round-corner transition.
The connection wing center section that the adjacent commutator segment is connected is set to circular configuration, and the face of the circular configuration and commutation
Piece is arranged in parallel.
The beneficial effects of the utility model are：Due to taking above-mentioned technical proposal, effectively improve existing commutator segment with
Matrix connection situation loosely, commutator structure design advantages of simple, by the way that the connection wing of adjacent commutator segment is connected and
Circular configuration is set in the middle part of the connection wing being connected, strengthens the conjugation between commutator segment and matrix, connection is more firm, safety,
Avoid that separated situation occurs, extend commutator service life, while temperature inductor is set in matrix, know commutator in time
Temperature, prevents unexpected generation, protects commutator, safe.

Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings.
As shown in Fig. 1 combinations Fig. 2, Fig. 3, a kind of commutator, including matrix 1 and commutator segment 2, described matrix are set at 1 center
There is through hole 5,2 back of commutator segment is equipped with the connection wing 3, and commutator segment 2 is fastened in matrix 1 by connecting the wing 3, and described one
A commutator segment 2 connects two connection wings 3, this two connection wings 3 are connected with the connection wing 3 of adjacent commutator segment 2；The one of commutator segment 2
End is connected with wiring hook 4, is distributed with concaveconvex structure 6 in the upper and lower surface of the connection wing 3, between the adjacent commutator segment 2
Equipped with insulation tank 21, the insulation tank 21 is equipped with insulator 22 close to the end in 4 direction of wiring hook to be interior, the insulator 22 and
Matrix 1 is an integral structure setting, is integrally formed when matrix 1 is molded, and face and insulation tank of the insulator 22 away from wiring hook 4
It is in chamfered transition between 21 bottoms, insulator 22 is added at this and effectively avoids the glue or its that wiring hook 4 uses in wiring
It fixes article and drops cause short circuit on commutator segment 2 the problem of, and temperature inductor, the temperature are equipped with described matrix 1
Inductor connects warning device or temperature indicating device, to real-time monitor commutator temperature, when temperature is excessive, stops in time
Only operation is safeguarded or repaired, and avoids the occurrence of accident, strengthens security.
The connection wing 3 is connected with 2 junction of commutator segment by 8 transition of rounding angle, strengthens the degree of being connected firmly of tie point,
It is not easy to break.
Connected 3 center section of the connection wing of the adjacent commutator segment 2 is set to circular configuration 7, and the face of the circular configuration 7 with
Commutator segment 2 is arranged in parallel, and circular configuration sets the combination power that greatly strengthen between commutator segment 2 and matrix 1.
The utility model effectively improves existing commutator segment 2 and situation loosely is connected with matrix 1, which sets
Advantages of simple is counted, circular configuration 7 is set by the middle part of the connection wing 3 that the connection wing 3 of adjacent commutator segment 2 is connected and is connected,
Strengthen the conjugation between commutator segment 2 and matrix 1, connection is more firm, safety, avoids that separated situation occurs, extends commutation
Device service life, while temperature inductor is set in matrix 1, the temperature of commutator is known in time, prevents unexpected generation, protection commutation
Device, it is safe.
Every technical staff's notice：Although the utility model is described according to above-mentioned embodiment, this
The invention thought of utility model is not limited to that utility model, and any repacking with inventive concept, will all include this specially
In sharp scope of patent protection.
