JP 2006-19046 A

  However, in the conventional rotary electric component as described above, in order to ensure proper connection between the pair of lead terminals included in the light emitting element and the conductive plate, the pair of lead terminals are formed in the rotation member. Therefore, there is a problem that workability during assembly is poor.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a rotating electrical component that is excellent in workability during assembly.

  A rotating electrical component of the present invention includes a case having a cylindrical portion, a hollow rotating body that is rotatably held in the case, a light emitting member that has a pair of lead terminals and is attached to the rotating body, A pair of conductive members attached to the rotating body and respectively conducting with the pair of lead terminals; a sliding member attached to the rotating body for detecting rotation of the rotating body; A substrate provided with a sliding contact pattern on which the sliding member is slidably contacted, and bending the pair of lead terminals to form a connection portion facing the substrate, while part of the conductive member is connected to the connection portion It is characterized by being elastically touched.

  According to the rotating electrical component, the pair of lead terminals of the light emitting member is bent to form a connection portion facing the substrate, while a part of the conductive member is elastically contacted with the connection portion. Since it is not necessary to insert into a predetermined through-hole in order to fix the position of a pair of lead terminal like the past, the workability | operativity at the time of an assembly can be improved. In addition, when the conductive member is attached to the rotating body, the connection state between the lead terminal connecting portion and the conductive member can be easily confirmed. As a result, it is possible to provide a rotating electrical component that is excellent in workability during assembly.

  In the rotating electrical component, each of the pair of conductive members includes an attachment portion attached to the rotating body, an elastic arm portion extending from the attachment portion and elastically contacting the connection portion, and extending from the attachment portion. Preferably, the elastic arm portion and the sliding contact piece protrude in different directions in the rotational axis direction of the rotating body. In this case, since the elastic arm portion and the sliding contact piece protrude in different directions in the rotation axis direction of the rotating body, the conductive member is elastically contacted with the connection portion of the lead terminal with a simple configuration, and also for power supply. It is possible to make sliding contact with the pattern.

  Further, in the rotating electrical component, the attachment portions of the pair of conductive members are attached to positions facing each other across the pair of lead terminals, and the elastic arm portions are the pair of leads. It is preferable that the terminal is elastically contacted with the lead terminal disposed at a distant position. In this case, since the length of the arm portion in the elastic arm portion can be ensured, the reliability of connection with the lead terminal can be improved.

  In particular, in the rotary electrical component, the connection portion is formed by bending the ends of the pair of lead terminals into an L shape, and extends from the inner peripheral side to the outer peripheral side of the rotary body, It is preferable that the arm part and the sliding contact piece extend in the same direction from each of the attachment parts. In this case, since the elastic arm portion and the sliding contact piece are provided in the same direction in plan view from the mounting portion, the yield rate of the material at the time of manufacture is improved and the rotation angle of the rotating body is ensured widely. It becomes possible.

  In the rotating electrical component, the sliding member is preferably arranged side by side in the radial direction of the conductive member and the rotating body. In this case, since the sliding member and the conductive member are arranged side by side in the radial direction of the rotating body, the space required for the conductive member and the sliding member can be reduced. Can be secured widely.

  For example, in the rotating electrical component, the sliding member is slidably contacted with the sliding pattern extending from each of the mounting portions and a pair of mounting portions that are mounted to face each other across the pair of lead terminals. It is preferable that the pair of sliding contact pieces have a pair of sliding contact pieces, and the pair of sliding contact pieces extend in the direction of the other mounting portion. In this case, since the pair of sliding contact pieces included in the pair of mounting portions arranged with the pair of lead terminals interposed therebetween extend in the direction of the mating mounting portion, the space required for the pair of sliding pieces is reduced. Therefore, it is possible to ensure a wide rotation angle of the rotating body.

  Further, in the rotating electrical component, the rotating body includes an operation shaft having a cylindrical portion and a click member provided with unevenness for imparting a click feeling, and the light emitting member includes an inner portion of the click member. It is preferable that the light emitting member is supported on the outer peripheral surface of the cylindrical portion of the operation shaft attached to the click member from the peripheral side. In this case, since the light emitting member is disposed between the operation shaft and the click member, the light emitting member can be easily attached and the light emitting member can be removed without requiring any special mounting work. It becomes possible to prevent.

  For example, in the rotating electrical component, the light emitting member is composed of a light emitting diode having the pair of lead terminals. In this case, since a part of the pair of conductive members is elastically contacted with the pair of lead terminals, it is not necessary to make the conductive member complicated, so that the yield rate of the material during manufacturing can be improved. The manufacturing cost can be reduced.

  In the rotating electrical component, the light emitting member includes a light source and a holding member that holds the light source and includes the pair of lead terminals. The pair of lead terminals are electrically conductive with the pair of electrodes of the light source, respectively. You may make it provide the 2nd connection part connected. In this case, since the light source can be attached to the rotating body via the holding member, for example, even when a chip-like light emitting diode is used as the light source, it can be arranged close to a desired illumination position. .

  In particular, in the rotating electrical component, the holding member is provided with the pair of lead terminals arranged side by side and a receiving portion for receiving the light source, and the second connection portion extends from the pair of lead terminals. It is conceivable to have protrusions that are provided at positions facing each other and elastically contact a pair of electrodes of the light source disposed in the receiving portion. In this case, since the protruding portion of the second connection portion can be elastically contacted with the pair of electrodes of the light source arranged in the receiving portion, the conduction state between the electrode of the light source and the lead terminal can be stabilized. Is possible.

  For example, in the rotating electrical component, the light source is configured by a chip-like light emitting diode. In this case, it is possible to provide a rotating electrical component that can cope with various emission colors by exchanging the chip-like light emitting diodes held by the holding member.

  According to the present invention, the pair of lead terminals of the light emitting member are bent to form the connecting portion facing the substrate, while a part of the conductive member is elastically contacted with the connecting portion. When attaching the conductive member to the rotating body, it is possible to check the connection state between the conductive member and the lead terminal without assembling the conductive member into the rotating body without fixing the position of the pair of lead terminals. It is possible to provide a rotating electrical component having excellent workability.
