Abstract
The utility model discloses a carbon brush frame assembly which comprises a brush seat, a brush box, a carbon brush and a torsion spring. The brush box is installed on the brush seat, the carbon brush is positioned in the brush box, the torsion spring is arranged on the brush seat, and an elastic rod of the torsion spring is in contact with the carbon brush. The carbon brush frame assembly is characterized in that an induction switch is positioned on the brush seat, the induction switch is in induction with the elastic rod of the torsion spring, and the induction switch is connected with a power supply controller. The carbon brush frame assembly can reflect a using state of the carbon brush to a power supply through the induction switch. When the carbon brush is abraded to a certain degree, a motor can stop running timely, current is prevented from being broken abruptly, short circuit is avoided, and production safety is improved.
Description
Technical field
The utility model relates to a kind of improvement invention of carbon brush holder assembly.
Background technology
Carbon brush in use can wear and tear, and carbon brush shortens gradually, and spring then promotes carbon brush always makes it contact with commutator; Long when carbon brush service time, when wearing and tearing are exaggerated; Carbon brush is because of the too short elastic force effect that does not receive spring, thereby no longer contacts with commutator, thereby causes phenomenons such as electric current interrupts suddenly, short circuit; Thereby influence the useful life of motor, and have certain potential safety hazard.
Summary of the invention
In view of the existing technical problem of background technology, the utility model technical problem to be solved provides a kind of stable, safe carbon brush holder assembly that uses.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to realize: this kind carbon brush holder assembly includes brush holder, brush box, carbon brush and torsion spring; Said brush box is installed on the brush holder, and said carbon brush places in the brush box, and said torsion spring is installed on the brush holder; The elastic rod of said torsion spring contacts with carbon brush; It is characterized in that said brush holder is provided with inductive switch, said inductive switch is responded to the elastic rod of torsion spring mutually, and said inductive switch is connected with power-supply controller of electric.
The utility model reacts the carbon brush user mode to power supply through inductive switch, and is when carbon brush may wear to a certain degree because of use, promptly just short because of the carbon brush wearing and tearing; When the elastic rod of spring promoted carbon brush to certain position, inductive switch was sensed the elastic rod of spring, and information is passed to and power-supply controller of electric; Close by the power-supply controller of electric instruction power, so in time stopped the motor operation, avoided the phenomenon of electric current interruption suddenly or short circuit; Avoid the impaired loss that causes of motor, make that also production is safer.
Description of drawings
Further describe the operation principle and the relevant details thereof of the utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model.
Sketch map when Fig. 2 is in sense state for the elastic rod of the utility model inductive switch and torsion spring.
Embodiment
With reference to accompanying drawing, this kind carbon brush holder assembly includes brush holder 6, brush box 2, carbon brush 1 and torsion spring 4; Said brush box 2 is installed on the brush holder 6, and said carbon brush 1 places in the brush box 2, and said torsion spring 4 is installed on the brush holder 6; The elastic rod 3 of said torsion spring contacts with carbon brush 1; Said brush holder 6 is provided with inductive switch 5, and said inductive switch 5 is responded to the elastic rod 3 of torsion spring mutually, and said inductive switch 5 is connected with power-supply controller of electric.
