Shield device is mounted in outside motor, is not fixed easily, cost is also higher.
Utility model content
The utility model provides a kind of high voltage direct current motor carbon brush board group part, and which overcome skills present in background technique
Art problem.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of high voltage direct current motor carbon brush board group part, including the pcb board being built in motor, pcb board upper surface collection
At the anti-electromagnetic interference circuit with EMC anti-interference function, thermistor is installed to mention to motor on the pcb board lower end surface
For Thermal protection and overcurrent protection.
In preferred embodiment, inductance and capacitor are installed on the pcb board lower end surface, the inductance and capacitor can form LC
Filter circuit is to reduce motor clutter.
In preferred embodiment, the pcb board upper surface is fixed with carbon brush sleeve, and the carbon brush sleeve is equipped with carbon brush；The carbon
There are four foot son, the carbon brush sleeves to be fixed on the pcb board by four foot sons for brushing tool.
It further include female terminal in preferred embodiment, the female terminal is connected by atom line with the pcb board, described
Pcb board carries out assembly connection by the female terminal and motor.
In preferred embodiment, the length of the pcb board is 20-120mm, outside diameter 20-100mm.
In preferred embodiment, border is arranged with for providing the Jiao Gai of electrical safety protection on the outside of the pcb board.
Compared with the prior art, it has the following advantages:
1, carbon brush board group part described in the utility model by electromagnetism interference prototype part and overheats overcurrent by pcb board
Protection prototype part integrates, the carbon brush board group part built-in motor, so that motor has EMC anti-interference function, overheating protection
And excess current protective function, simple installation, securely and reliably.
2, border is arranged with Jiao Gai on the outside of pcb board, is also user while providing insulating protection for entire carbon brush board group part
Security protection is provided.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the cross-sectional view of the utility model；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the utility model circuit diagram.
Specific embodiment
Please refer to Fig. 1 and Fig. 2, a kind of high voltage direct current motor carbon brush board group part, including the pcb board (print being built in motor
Circuit board processed) 1, the pcb board upper surface 11 is integrated with anti-electromagnetic interference circuit 2, is equipped with heat on the pcb board lower end surface 12
Quick resistance 3 is to provide Thermal protection and overcurrent protection to motor.
In the present embodiment, the length of the pcb board 1 is 120mm, outside diameter 100mm.
Specifically, which has EMC (Electro Magnetic Compatibility) anti-interference function.The thermistor 3
(PTC) there is PTC heat protection function and excess current protective function, provide effective duplicate protection to motor.When thermistor overheats
Or after overcurrent protection, when not powering off, temperature is more than that 110 DEG C or internal resistance increase, and holding circuit disconnects, and provides motor guarantor
Shield, it is therefore prevented that because abnormal operation causes coil temperature excessively high, the dangerous situations such as fire occur, it is ensured that user uses safe.
In specific structure, the pcb board upper surface 11 is fixed with carbon brush sleeve 4, and the carbon brush sleeve 4 is equipped with carbon brush (in figure
It is not shown), the carbon brush can turn on wiring board and be powered with rotor.In addition, the carbon brush tool is there are four foot son, it is described
Carbon brush sleeve is riveted on the pcb board 1 by four foot son fixations.
Inductance 5 and capacitor 6 are installed, the inductance 5 and capacitor 6 form LC filter circuit, reduce electricity on the pcb board 1
Influence of the machine clutter to power grid.
It is mentioned as shown in figure 3, the carbon brush board group part is integrated with LC filter circuit, the thermistor 3 that inductance 5 and capacitor 6 form
The Thermal protection and current protecting circuit of confession are provided for circuit and are effectively protected when motor accesses 220V-240V voltage.
In the present embodiment, which further includes the female terminal 8 being connected by atom line 7 with the pcb board, institute
It states carbon brush plate and assembly connection is carried out by the female terminal 8 and motor.
In the present embodiment, border is arranged with glue lid 9 on the outside of the pcb board, provides insulating protection for entire carbon brush board group part
While also provide security protection for user.
Carbon brush board group part described in the utility model by electromagnetism interference prototype part and overheats over current protection by pcb board
Shield prototype part integrate, the carbon brush board group part built-in motor so that motor have EMC anti-interference function, overheating protection and
Excess current protective function, simple installation, securely and reliably.
The above, only the utility model preferred embodiment, therefore, it cannot be limited according to, and the utility model is implemented
It is practical new to should still belong to this for range, i.e., equivalent changes and modifications made according to the scope of the patent of the utility model and the content of the manual
In the range of type covers.
