Definitions

  • the present disclosure relates to a slide switch having a slide member rotatably supported on a housing, and an operating lever device having the same.
  • Slide switches are used in the control levers of construction machinery and various other devices.
  • One example of a slide switch is the rotation control device of Patent Document 1.
  • the moving actuator is configured to be rotatable around an axis (i.e., slidable).
  • a signal is output when the moving actuator rotates by more than a predetermined angle in each of the first and second directions.
  • a slide switch such as the rotation control device of Patent Document 1
  • a magnetic sensor mechanism in the slide switch.
  • a magnetic sensor mechanism for example, a magnet is placed on a slide member that corresponds to the moving actuator. Then, a signal according to the amount of rotation is output by detecting the change in the magnetic field of the magnet when the slide member rotates with a sensor.
  • a mounting hole is formed in the slide member around the rotation axis. Then, a magnet is embedded in the mounting hole during assembly. When embedding the magnet, the mounting hole is filled with a filler such as an adhesive or resin material, thereby fixing the magnet to the mounting hole.
  • the magnet When assembling such a slide switch, the following can occur. That is, the magnet may not be embedded in the mounting hole. Also, the magnet needs to be embedded and fixed in the mounting hole in a specified position, but it may be embedded in the mounting hole in an incorrect position (for example, tilted) due to a malfunction in the work. Forgetting to embed or embedding in an incorrect position is difficult to confirm unless an output signal inspection is performed on all products after assembly. Therefore, it is required to be able to easily confirm forgetting to embed or embedding in an incorrect position. Furthermore, when a magnetic sensor mechanism is used, the respective positions of the magnet and sensor affect the accuracy of the detection result. Therefore, it is required that the sensor be positioned accurately in the desired position relative to the magnet.
  • the first disclosure therefore aims to provide a slide switch that can easily check whether a magnet has been left embedded or embedded in an incorrect position, and an operating lever device that is equipped with the slide switch.
  • the second disclosure also aims to provide a slide switch in which a sensor can be accurately positioned at a desired position relative to a magnet, and an operating lever device equipped with the same.

  • the cover member is formed shorter than the mating portion by the amount that the magnet protrudes into the mating portion in the axial direction. Therefore, the state of the magnet being housed can be confirmed by the state of fit of the cover member in the mounting hole. For example, if the cover member is housed in the mounting hole in a state where it protrudes from the opening of the mounting hole, it can be confirmed that the magnet is housed in the housing portion in a premature position. On the other hand, if the cover member is inserted into the mounting hole in a state where it is recessed relative to the opening of the mounting hole, it can be confirmed that the magnet has been forgotten to be inserted into the housing portion.

  • the senor has a detection unit that detects changes in a magnetic field, and is positioned in the first direction by abutting the detection unit against the positioning unit. Therefore, it is possible to improve the positioning accuracy of the sensor in the housing, particularly the detection unit, in the first direction.

  • the slide switch 1 In the slide switch 1, a finger such as a thumb is pressed against the operating portion 33 of the slide member 16. Then, by pushing and pulling the operating portion 33 with the finger, the slide member 16 is rotated in one circumferential direction or the other (see arrow A in FIG. 1). This causes the magnet 41 provided on the shaft portion 31 to rotate around the rotation axis L1. This changes the magnetic field of the magnet 41. The sensor 42 then outputs a signal according to the amount of rotation of the slide member 16 based on the change in the magnetic field of the magnet 41. In this way, the slide switch 1 outputs a signal according to the amount of operation of the slide member 16.
  • the cover member 36 is formed shorter than the fitting portion 35b by the amount of protrusion ⁇ by which the magnet 41 protrudes into the fitting portion 35b in the axial direction. Therefore, the accommodation state of the magnet 41 can be confirmed by the fitting state of the cover member 36 in the mounting hole 35. For example, if the cover member 36 is fitted into the mounting hole 35 in a state where it protrudes from the opening 35d of the mounting hole 35, it can be confirmed that the magnet 41 is accommodated in the accommodation portion 35a in an incorrect position (e.g., tilted state, etc.).

  • the housing portion 35a has a plurality of crush ribs 35c on the inner peripheral surface. Therefore, the magnet 41 is housed in the housing portion 35a in a fitted state. This improves the press-fittability (i.e., ease of press-fitting) of the magnet 41 into the housing portion 35a and improves the positioning accuracy of the magnet 41.
  • the cover member 36 is an expandable press-fit pin. Therefore, the cover member 36 is prevented from coming off the mounting hole 35. Therefore, the magnet 41 is prevented from coming off.
  • the sensor 42 has a detection portion 42a that detects changes in the magnetic field, and is positioned in the first direction by abutting the detection portion 42a against the positioning portion 27b. Therefore, the positioning accuracy of the sensor 42, particularly the detection portion 42a, in the housing 15 in the first direction can be improved.
  • the sensor 42 is inserted into the sensor housing 27 so that both ends of the substrate 42b in the second direction abut against both side portions in the second direction of the sensor housing 27.

  • the cover member is formed shorter than the mating portion by the amount that the magnet protrudes into the mating portion in the axial direction. Therefore, the state of the magnet being housed can be confirmed by the state of fit of the cover member in the mounting hole.
