[0026] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0027] Please refer to Figures 1 - 4 , the present application provides an easily assembled motor commutator, including a base 10 and a commutator segment 20. The commutator segment 20 is radially inserted into the base 10. A ferrule 30 is axially inserted into the base 10. The ferrule 30 is clamped with the commutator segment 20. A rotating shaft 40 is tightly inserted into the ferrule 30. Among them, after all the commutator segments 20 are inserted into the base 10, the ferrule 30 is used to clamp all the commutator segments 20, and then the rotating shaft 40 is used to tightly press against the ferrule 30, so as to complete the assembly of all structures. The operation is simple and the connection is firm.

[0028] Please refer to Figures 1 - 4 , two weld seams 50 are provided on the commutator segment 20. The two weld seams 50 facilitate more stable welding of the wires.

[0029] Please refer to Figures 1 - 4 , the commutator segment 20 includes a wiping piece 21 and a plug 22. A groove adapted to the commutator segment 20 is provided on the base 10. The plug 22 is fixedly connected to the back of the plug 22. The plug 22 is inserted into the base 10 and clamped with the ferrule 30. The plug 22 and the wiping piece 21 are integrally formed. When the plug 22 is inserted into the base 10, the wiping piece 21 itself also enters the groove, which is convenient for accurate positioning.

[0030] Please refer to Figures 1 - 4 , the ferrule 30 includes an inner sleeve 31 and an outer sleeve 32. The outer sleeve 32 is inserted into the inner sleeve 31. The plug 22 has an inverted T-shaped structure. The inner sleeve 31 and the outer sleeve 32 clamp the plug 22 from both sides. After the plug 22 is inserted into the base 10, the inner sleeve 31 and the outer sleeve 32 are respectively inserted into the base 10 from both ends of the base 10, and the plug 22 is clamped from both sides of the plug 22, and the clamping is more firm.

[0031] Please refer to Figures 1 - 4 , one end of the inner sleeve 31 is provided with a spring catch 33. A buckle groove adapted to the spring catch 33 is provided on the outer sleeve 32. The rotating shaft 40 is movably pressed against the spring catch 33. After the inner sleeve 31 and the outer sleeve 32 are inserted into the base 10, the spring catch 33 on the inner sleeve 31 is snapped into the buckle groove on the inner sleeve 31. In this way, a snap connection is formed between the inner sleeve 31 and the outer sleeve 32. Then the rotating shaft 40 is inserted into the inner sleeve 31, so as to press against all the spring catches 33. In this way, the spring catches 33 cannot be disengaged from the buckle groove, and a firm connection is formed between the inner sleeve 31 and the outer sleeve 32.

[0032] Please refer toFigures 1 - 4 A key 60 is provided between the rotating shaft 40 and the base 10. The key 60 passes through the ferrule 30. First, the key 60 is inserted into the keyway on the rotating shaft 40, and then when the whole is inserted into the base 10, the key 60 is also inserted into the inner sleeve 31 and the outer sleeve 32, so as to circumferentially fix the base 10, the ferrule 30 and the rotating shaft 40 together.

[0033] The working principle of this easily assembled motor commutator is as follows: all the commutator segments 20 together with the plug 22 are inserted into the base 10, then the inner sleeve 31 and the outer sleeve 32 are respectively inserted from both ends of the base 10 to clamp the plug 22 from both sides of the plug 22. At the same time, the elastic buckle 33 on the inner sleeve 31 is snapped into the buckle groove on the inner sleeve 31, so that a snap connection is formed between the inner sleeve 31 and the outer sleeve 32. Then the key 60 is inserted into the keyway on the rotating shaft 40, and when the whole is inserted into the base 10, the key 60 is also inserted into the inner sleeve 31 and the outer sleeve 32, so as to circumferentially fix the base 10, the ferrule 30 and the rotating shaft 40 together. After the rotating shaft 40 is inserted into the inner sleeve 31, it abuts against all the elastic buckles 33, so that the elastic buckles 33 cannot be disengaged from the buckle grooves, and a firm connection is formed between the inner sleeve 31 and the outer sleeve 32. In summary, after all the commutator segments 20 are inserted into the base 10, the ferrule 30 is used to clamp all the commutator segments 20, and then the rotating shaft 40 is used to abut against the ferrule 30 to complete the assembly of all the structures. The operation is simple and the connection is firm.
