Encoder without backstop

Abstract

An encoder without a backstop relates to an electronic component, which comprises a rotatary shaft, a shaft sleeve, a locking pedestal, a location shrapnel, a diaphragm, at least a swing arm, at least an electric brush and at least a body successively arranged from bottom to up. The innovative characteristics include the rotatary shaft and the locking pedestal are not provided with a backstop structure; the rotatary angle of the rotatary shaft equals to or is bigger than 360 degree; the electric brush comprises a plastic wrapping part, a bending part, an elastic arm and the brush head; the plastic wrapping part, the bending part, the elastic arm and the brush head are integrally moulded to an integral structure; the plastic wrapping part wraps the swing arm with plastic; the bending part connects the plastic wrapping part with the elastic arm and bends the elastic arm towards the plastic wrapping part; the elastic arm comprises a main arm and a branch arm; the main arm is a microsclercircular body; and the brush head presses the free ends of the main arm and the branch arm. The beneficial effects include channels in use are increased to 32 or more, bringing convenience to programming and actual operation control; and the electric brush does not become flexible, making the electric brush and the encoding circuit stably contact.

Description

technical field [0001] The utility model relates to electronic components, in particular to a non-stop encoder without a stop structure. Background technique [0002] Rotary encoders are very versatile. In the prior art, the shaft of the rotary encoder passes through the shaft hole of the shaft sleeve so that the shaft can rotate freely in the shaft hole of the shaft sleeve; a stop seat is also provided, and a shaft hole matching the shaft is formed on the stop seat to make the stop The moving seat rotates with the shaft. Simultaneously, a stopper structure is set on the rotating shaft and the stop seat to limit the angle of rotation of the rotating shaft, such as only rotating 320 degrees. Generally speaking, the stop structure is a stop block respectively arranged on the rotating shaft and the stop seat. When the two stop blocks collide, the rotating shaft can no longer rotate forward and can only be reversed. If the rotating angle (such as 320 degrees) of the rotating ...

Problems solved by technology

When the height of the brush head of the brush changes the same, because the length of the elastic arm of the brush is too short, the angle between the elastic arm of the brush and the plane of the arm seat plate changes greatly, and it is easy to cause the brush to loosen. At the same time, when the brush rotates with the rotating shaft, the elastic arm of the brush fluctuates greatly, which also causes the contact between the brush and the circuit chip to be unstable.
