Description

Technical Field

[0001] The utility model relates to the field of encoder design, in particular to an incremental encoder. Background Art

[0002] An incremental encoder is an adjustable electronic component that converts the direction and amount of rotation into high and low level digital pulse signal outputs. The digital signal is very convenient to be processed by a single-chip microcomputer. Incremental encoders are often used in power regulation such as volume control and speed control, and are widely used in the field of electronic production.

[0003] The connection terminals and brushes of current incremental encoders are usually integrally injection-molded, which is difficult and costly to process. In addition, the brushes are easily deformed, which affects the stability of the encoder during operation and greatly reduces the user experience.

[0004] Therefore, it is necessary to propose a technical means to solve the above defects. Utility Model Content

[0020] See also Figures 1 to 3, an incremental encoder includes a mounting base 10, an undulating disk 20, a rotating shaft 40, a brush 50 and a connecting terminal 60; the undulating disk 20 is rotatably mounted on the mounting base 10; the rotating shaft 40 is mounted on the undulating disk 20 and is used to drive the undulating disk 20 to rotate; the brush 50 is installed between the undulating disk 20 and the mounting base 10 and is used to work in conjunction with the undulating disk 20; the connecting terminal 60 is installed on the mounting base 10, and one end of the connecting terminal 60 is riveted to the brush 50, and the other end extends from the side of the mounting base 10 to the bottom of the mounting base 10.

[0021] In this embodiment, during operation, the external drive shaft 40 rotates, thereby driving the fluctuation plate 20 to rotate, thereby causing the relative positions of the fluctuation plate 20 and the brush 50 to change, thereby generating an electrical signal, which is then output to the external control system through the connection terminal 60;

[0022] In this embodiment, since the brush 50 and the connecting terminal 60 are riveted together, compared with the traditional brush 50 and the connecting terminal 60 being integrally injection molded, the processing difficulty is reduced, and the brush 50 is not easily deformed, thereby effectively improving the stability of the brush 50 during operation.

[0023] In a specific embodiment, the mounting base 10 is provided with a mounting groove 101; the fluctuating disc 20 is rotatably mounted in the mounting groove 101. Specifically, a connecting post is provided at the bottom center of the fluctuating disc 20, and a connecting hole 102 for mounting the connecting post is provided at the center of the mounting groove 101.

In this embodiment, the buckle hole 801 and the buckle block 103 ensure that the bracket 80 is effectively assembled with the mounting base 10 during installation. Furthermore, the device further includes a spring clip 90 mounted between the sleeve 70 and the undulating plate 20. Specifically, in this embodiment, the provision of the spring clip 90 increases the damping effect when the rotating shaft 40 rotates, thereby effectively improving the user experience. Furthermore, a waterproof ring 100 is provided between the sleeve 70 and the rotating shaft 40. Furthermore, a waterproof gasket 30 is provided between the sleeve 70 and the mounting base 10.
