In one aspect, the present embodiments provide a button. Referring to fig. 1 and 2, the button includes a straight-slide potentiometer 10 and an insulating press 20.

The straight slide potentiometer 10 has a resistor body, and a slide push rod 12 and a pin 13 connected to the resistor body, respectively, wherein the pin 13 is used for electrically connecting with a circuit board 60 in an electronic device. The insulation pressing member 20 is provided with a fixing sleeve 221, and the sliding push rod 12 can be detachably inserted into the fixing sleeve 221. When the insulation pressing piece 20 is pressed, the insulation pressing piece 20 can drive the sliding push rod 12 to move along the length direction of the resistor body through the fixing sleeve 221, so that the resistance value of the resistor body is changed linearly. At this time, the resistance value change signal of the resistor is a linear gradual change signal. The linearly tapered signal may then be output to circuit board 60 via pin 13 for use by an electronic device.

It can be seen that the output of the linear gradation signal can be realized by the push button provided by the present embodiment as well as compared with the knob. On this basis, the button that this embodiment provided only needs the combination of straight sliding potentiometer 10 and insulating pressing member 20 to realize signal output work, and spare part quantity is less, and the structure is simpler, and maintainability is better.

For the straight slide potentiometer 10, referring to fig. 3 and 4, it includes a potentiometer housing 11, and a resistor (not shown in the figure) is enclosed in the potentiometer housing 11.

The lead 13 is connected to the resistor and extends out of the potentiometer housing 11. Since the structures of the potentiometer housing 11, the resistor, the sliding push rod 12 and the pins 13 are all the prior art, the detailed description is omitted here.

Accordingly, the moving accuracy of the insulating pressing member 20 can be ensured by the cooperation of the slide grooves 222 and the slide rails 311. When the device is specifically arranged, the sliding grooves 222 can be arranged on the circumferential outer wall of the cylinder 22, and the number of the sliding grooves 222 can be adjusted according to actual needs.

Of course, along the moving direction of the insulation pressing member 20, the sliding rail 311 may be provided on the insulation pressing member 20, and the sliding groove 222 may be provided on the base 30, so that the sliding groove 222 is slidably connected to the sliding rail 311, and the moving accuracy of the insulation pressing member 20 may be ensured.

Optionally, for easier installation, a partition 33 is disposed in the circumferential housing 31 along the axial direction thereof, and the partition 33 divides the inner cavity of the circumferential housing 31 into a first accommodating chamber and a second accommodating chamber. Wherein, the straight sliding potentiometer 10 is arranged in a first accommodating cavity, and the insulating pressing piece 20 is arranged in a second accommodating cavity. An escape opening 331 is further provided in the partition 33 to prevent the presence of the partition 33 from obstructing the movement of the slide push rod 12.

Optionally, a sliding hole 312 is further formed in the circumferential wall surface of the circumferential housing 31, and the sliding hole 312 is arranged along the moving direction of the insulating pressing member 20; accordingly, a protrusion 223 is provided on the insulating pressing member 20, and the protrusion 223 is engaged in the sliding hole 312 and can move along the length direction of the sliding hole 312, so that the insulating pressing member 20 can be prevented from being removed from the base 30 when moving.

In terms of material, the insulating pressing member 20 and the base 30 may be made of plastic to obtain excellent insulating performance and reduce cost.

In some embodiments, an elastic restoring member 40 is further provided in the button to restore the insulation pressing member 20. Specifically, referring to fig. 3, the elastic restoring member 40 is disposed between the insulating pressing member 20 and the base 30 in a moving direction of the insulating pressing member 20. When the insulation pressing member 20 is pressed, the elastic restoring member 40 is compressed by a force; when the insulation pressing member 20 is released, the elastic restoring member 40 provides an elastic force to restore the insulation pressing member 20.

Alternatively, referring to fig. 3, resilient return member 40 may be provided as a spring. The two ends of the spring are respectively connected with the insulation pressing piece 20 and the base 30 in a plugging way. The structure is simple, and the dislocation of the two ends of the spring can be avoided in the spring stretching process, so that the accuracy of the position of the spring is ensured.

As one example, a spring is mounted to the second receiving cavity and is positioned between the post 22 and the end cap 32. Further, referring to fig. 3 and 5, a slot 224 is provided on a side of the column 22 facing the end cap 32, and one end of the spring is inserted into the slot 224; referring to fig. 3 and 6, a plug column 321 is disposed on a side of the end cap 32 facing the column 22, and the other end of the spring is plugged onto the plug column 321.

In some embodiments, referring to fig. 1, the button further comprises a positioning post 50. The base 30 can be positioned and fixed on the circuit board 60 through the positioning columns 50, so that the base 30 can be accurately installed.

In some embodiments, the positioning column 50 and the base 30 are molded as an integral structure, so that the whole structure is more stable and reliable. Alternatively, referring to fig. 1 and 7, one end of the positioning post 50 is integrally molded with the end cap 32, and the other end extends toward the circuit board 60 to connect to the circuit board 60. As an example, the base 30 can be fixed by soldering the positioning posts 50 on the circuit board 60. Of course, the positioning column 50 can be screwed with the circuit board 60 to realize the detachable connection of the base 30, which is more convenient for the installation or replacement of the whole button.

It is understood that, in actual operation, the order of the above partial steps may be changed, and the assembly of the button may be implemented. For example, the elastic restoring member 40 may be installed in the base 30, and then the straight-sliding potentiometer 10 and the insulation pressing member 20 may be connected to each other, so that the straight-sliding potentiometer 10 and the insulation pressing member 20 may be installed.

On the other hand, the embodiment also provides an electronic device which comprises the button. In particular, the electronic device may be a laboratory instrument, an industrial display, an industrial controller, a medical instrument, a household appliance, or other consumer electronics product.

In some embodiments, the electronic device may further include a controller and an electronic switch that may cooperate with the button to implement a switching function. Taking the controller as a single chip microcomputer and the electronic switch as a triode as an example, the single chip microcomputer and the triode can be integrated on the circuit board 60, the input end of the single chip microcomputer is connected with the pin 13 in the button, and the output end of the single chip microcomputer is connected with the base electrode of the triode. At the moment, after the button is pressed, the singlechip can receive a signal output by the button; then, the single chip microcomputer can output the signal to the triode and control the conduction or the cut-off between the emitter and the collector of the triode, thereby realizing the switching function. In summary, the present application provides a button and an electronic device, in which a straight-sliding potentiometer 10 and an insulation pressing member 20 are connected to each other, and the insulation pressing member 20 drives the sliding push rod 12 to move, so that the resistance of the straight-sliding potentiometer 10 changes linearly, and a linear gradual change signal is obtained.
