Description

Rotary controller with switch

technical field

The utility model relates to a rotary controller with a switch, in particular to a rotary encoder or a rotary variable potentiometer which is combined with a switch device and has a switch function.

Background technique

Please refer to FIG. 1 . FIG. 1 is an exploded view of a rotary controller 2 in the prior art. The rotary controller 2 is, for example, a rotary encoder or a rotary variable potentiometer.

Rotary encoders are often used in electronic devices, and their components are generally shown in Figure 1. In its application, for example, in the field of automation control, it is used to detect the sensor elements of angle, position, speed, distance, count, and acceleration, and control the electrical signal through the rotary encoder to convert the actual mechanical parameter value into A coded signal that is processed by a computer.

The rotary encoder has a ring-shaped electrode composed of a common electrode and a coding electrode. The coding electrode has a plurality of insulating regions at intervals, and the ring-shaped electrode is contacted by a plurality of elastically protruding contact claws of the mover. During operation, when the actuator is rotated, at least one contact claw will maintain electrical contact with the common electrode, while the other contact claws will contact the coding electrode and the insulating area at intervals, so that the passage and disconnection of electrical signals are generated and combined. the coded signal.

In addition, there is also a rotary variable potentiometer, the main components of which are generally shown in Figure 1, which is also an electronic component commonly used in electronic equipment. By rotating the rotating spindle 8, the resistance value of the circuit in the electronic device is changed, thereby generating a potential signal. Applications such as audio or other multimedia equipment volume, treble, balanced output, contrast, hue and other video and audio adjustments.

The principle is as follows: a high-resistance conductor is used to form a ring-shaped electrode, and then the contact claw elastically protruding from the movable member is used to electrically contact the ring-shaped electrode. During operation, turning the movable member will make the contact claws electrically contact and move to the ring-shaped electrode, and a potential change will be generated through the constantly changing resistance value, thereby generating a potential signal.

These electronic components such as rotary encoders or rotary variable potentiometers can be collectively referred to as a rotary controller 2. In response to actual needs, the switch device 4 is further combined with the bottom of the rotary controller 2. Therefore, in addition to generating coded signals or potential signals, switching signals can also be generated.

The switch device 4 includes a switch shrapnel 402 and a switch body 404. The switch body 404 is installed under the rotary controller 2 such as a rotary encoder or a rotary variable potentiometer. There is a switch electrode on the upper surface of the center of the switch body 404. 406 , the entire switch device 4 is formed by injection molding the switch body 404 to cover the switch elastic piece 402 and the switch electrode 406 to form an integrated component. The switch shrapnel 402 is an arc-shaped elastic conductor, which is arranged between the switch body 404 and the rotary controller 2 and bulges upward, so that the upper and lower parts of the switch shrapnel 402 correspond to the switch electrode 406 and between the switch electrode 406 with a spacing.

When the rotating spindle 8 of the rotary controller 2 is pressed, the rotating spindle 8 presses the switch elastic piece 402 below, and then the switch elastic piece 402 electrically contacts the switch electrode 406 downward to generate the switch signal. Then, after removing the external force pressing the rotating main shaft 8 , the rotating main shaft 8 is returned to its original position by using the elastic restoring force of the switch shrapnel 402 .

However, when the lower end of the rotating spindle 8 is used to poke the upper surface of the arc-shaped switch spring 402, since the friction coefficient between metals is small, the texture and reliability of the operation are poor, and even the surface of the switch spring 402 will be damaged. As a result, the service life of the entire electronic component is reduced.

Therefore, in order to stabilize the operation and protect the switch shrapnel 402, the existing solution is to add an insulating lining 408 between the top of the switch shrapnel 402 and the rotary controller 2, and press the insulating lining 408 by rotating the lower end of the main shaft 8, By indirect pressure contact with the switch shrapnel 402, furthermore, the insulating lining 408 made of plastic material also has the effect of insulation. However, it will also increase the component cost and increase the process steps of assembly.

Therefore, the main purpose of the present invention is to provide a rotary controller with a switch to improve the above problems.
