JP 2007-323944 A

  However, in the above-described conventional slide switch, the coil spring and the click mechanism are arranged side by side in a direction orthogonal to the slide direction of the slide member, so that there is a problem that the size of the slide switch in that direction increases. .

  The present invention has been made in view of such problems, and an object of the present invention is to provide a slide-type electrical component capable of reducing the size of the slide member in the direction orthogonal to the slide direction.

  The slide type electric component of the present invention includes a case having a storage portion, a slide member provided so as to be slidable within the case, a slide movement detecting means for detecting the slide movement of the slide member, A leaf spring provided with an engaging projection that engages and disengages with the engaging portion provided on the slide member as the slide moves, and a state before the slide member that is elastically deformed with the slide movement of the slide member A coil spring that is returned to the position, and the plate spring is disposed so that the plate surface intersects the inner bottom surface of the storage portion, and the engagement protrusion of the plate spring is on an extension line in the compression direction of the coil spring. It is characterized in that at least a part of the part protrudes.

  According to the slide type electrical component, the leaf spring is disposed so as to intersect the inner bottom surface of the housing portion of the case, and the coil spring and the engagement protrusion of the leaf spring are disposed so as to overlap. Therefore, even in a slide-type electrical component having an automatic return function of the slide member and a click mechanism associated with the slide operation, the size of the case in the direction orthogonal to the slide direction of the slide member can be reduced. It is possible to provide a slide-type electrical component having a reduced size.

  In the slide-type electrical component according to the present invention, the engaging portion is constituted by a part of the first metal plate embedded in the sliding member, and the second metal in which the engaging protrusion is formed in a part. It is preferable that the leaf spring is constituted by a plate. In this case, since both the engaging portion of the slide member and the engaging protrusion of the leaf spring constituting the click mechanism can be made of a metal material, a good click feeling can be ensured over a long period of time. Is possible.

  In particular, in the slide-type electrical component of the present invention, the engagement portion is formed by an engagement piece obtained by bending a part of the first metal plate, and one end portion of the engagement piece is formed of a metal wire. The coil spring is preferably driven to compress. In this case, the coil spring can be compressed and driven at one end of the engagement piece of the first metal plate that functions as a part of the click mechanism, so that it is necessary in a direction orthogonal to the slide direction of the slide member. The size of the case to be reduced can be further reduced, and the size of the slide type electric component in the direction can be further reduced. Further, since the coil spring made of the metal wire is compressed and driven by the engagement piece which is a part of the first metal plate, the slide member can be automatically returned with high accuracy over a long period of time.

  Further, in the slide type electric component of the present invention, the slide member is based on a first state in which the engagement portion is disposed between one end of the coil spring and the engagement protrusion of the leaf spring. When the coil spring is slid in one direction, the coil spring is in a second state where the coil spring is compressed. It is preferable that the side end portion is held in the third state so as to face the engagement protrusion so as to be able to come into contact therewith. In this case, the slide member is automatically restored when slid in one direction, while the slide member is held in a locked (hold) state while causing a click feeling when slid in the other direction. It is possible to provide a slide-type electrical component that can be used. For example, it is possible to provide a slide-type electrical component that can prevent an undesired operation by holding it in the third state (lock (hold) state) in an unused state. More specifically, when the present slide-type electrical component is applied to a power switch, it is possible to prevent a situation where the power switch is accidentally turned on, and it is possible to avoid consumption of a battery or the like.

  Furthermore, in the slide-type electrical component according to the present invention, the storage portion includes a first storage portion and a second storage portion that are partitioned by a partition wall erected on the inner bottom surface, and the first storage portion includes the first storage portion. It is preferable to house the coil spring and the leaf spring in the second housing part while housing the slide movement detecting means. In this case, the slide movement detecting means, the coil spring, and the leaf spring are housed in the first housing part and the second housing part respectively partitioned by the partition wall, so that the slide member slides as the slide member slides. Even when wear powder is generated from the engagement portion of the member or the engagement protrusion of the leaf spring, the situation where the wear powder enters the slide movement detecting means side can be reduced. Parts can be provided.

  For example, in the slide-type electrical component of the present invention, the slide movement detecting means is provided on the slide member, the fixed contact or conductive pattern exposed from the inner bottom surface of the first storage portion, and the fixed contact or conductive pattern. It consists of a movable contact that is in sliding contact. Thus, even when the contact-type slide movement detecting means is adopted, it is possible to prevent the abrasion powder generated by the slide movement of the slide member from entering the sliding contact portion of the movable contact with respect to the fixed contact and the like. Can be increased.

  Furthermore, in the slide-type electrical component of the present invention, it is preferable that the first metal plate extends from one end of the slide member to the other end along the slide movement direction of the slide member. In this case, since the first metal plate extends from one end of the slide member to the other end, the strength is ensured even when the slide member is formed of a resin material and is downsized. It becomes possible.

  In particular, in the slide-type electrical component of the present invention, a part of the first metal plate is disposed between the cover member that closes the storage portion and the end surface of the partition wall, and the first metal plate It is preferable that the slide member is guided so as to be slidable at a part thereof. In this case, since the gap between the partition wall and the cover member can be reduced by a part of the first metal plate used for guiding the slide movement of the slide member, this occurred with the slide movement of the slide member. It is possible to make it difficult for the wear powder to enter the slide movement detecting means side, and it is possible to further improve the reliability.

  According to the present invention, the leaf spring is disposed so as to intersect the inner bottom surface of the housing portion of the case, and the coil spring and the engagement protrusion of the leaf spring are disposed so as to overlap. Even in slide-type electrical components that have a slide member automatic return function and a click mechanism that accompanies a slide operation, the dimensions of the case in the direction orthogonal to the slide direction of the slide member can be reduced, so the dimensions in that direction are small It is possible to provide a slide-type electrical component.

In the initial state of the slide member 5 shown in FIGS. 9 and 10, the engaging piece 53 a is sandwiched between the engaging protrusion 41 and the coil spring 3, and the bent portion 24 c of the partition wall 24 and the protruding piece 21 b of the partition wall 21. It is the state arrange | positioned in the clearance gap 24e between. Since the engagement piece 53a is sandwiched between the engagement protrusion 41 and the coil spring 3 in this manner, the slide member 5 is prevented from rattling in the initial state. In the initial state, the arms 72a and 72b of the movable contact 7 fixed to the slide member 5 are in contact with the common fixed contact 27a and the central fixed contact 27b, respectively.

  In the slide switch 1 according to the present embodiment, the first storage portion 22 stores the fixed contact 27 and the movable contact 7 constituting the slide movement detection means, while the second storage portion 23 stores the coil spring 3 and the leaf spring 4. Is housed. As a result, the slide movement detecting means, the coil spring 3 and the leaf spring 4 are housed in the first housing portion 22 and the second housing portion 23 which are partitioned by the partition wall 21, respectively. Accordingly, even when wear powder is generated from the engagement piece 53a of the slide member 5 or the engagement protrusion 41 of the leaf spring 4, etc., it is possible to prevent the wear powder from entering the slide movement detecting means side. It is possible to realize the slide switch 1 having excellent reliability.

  In particular, the slide switch 1 according to the present embodiment has been described with respect to the case where the contact-type slide movement detecting means including the fixed contact 27 and the movable contact 7 is provided. Especially when the detecting means is adopted, it is possible to prevent a situation in which wear powder generated by the sliding movement of the slide member 5 enters the sliding contact portion between the fixed contact 27 and the movable contact 7 to cause a contact failure. It is possible to improve the nature. The configuration of the slide movement detecting means is not limited to this, and can be changed as appropriate. For example, the slide movement is detected by a conductive pattern made of a resistor or the like provided on the inner bottom surface of the first storage portion 22 and a slider as a movable contact provided on the slide member 5 and sliding on the conductive pattern. You may make it comprise a means.

  In the assembled state, the slide member 5 is configured to be slidable to the right side of the slide switch 1 while enabling automatic return to the initial state. The slide member 5 is configured to be slidable to the left side of the slide switch 1 while providing a click feeling (moderation feel), and is configured to be able to be locked when slid to the left side. ing. For this reason, for example, on the basis of the initial state, the slide member 5 is slid to the right side of the slide switch 1, and the power is turned on / off, and the slide switch 1 is slid to the left side of the slide switch 1. It can be suitably used for a power switch that switches the power supply state to a locked (hold) state.

  Hereinafter, the operation of the slide switch 1 according to the present embodiment will be described. 11 and 12 are a perspective view and a top view when the slide member 5 included in the slide switch 1 according to the present embodiment is slid rightward from the initial state. 13 and 14 are a perspective view and a top view when the slide member 5 included in the slide switch 1 according to the present embodiment is slid leftward from the initial state. 11 to 14 show a state in which the cover member 6 is removed from the slide switch 1 for convenience of explanation.

  When the slide member 5 is slid rightward from the initial state shown in FIGS. 9 and 10, the engagement piece 53 a of the slide member 5 compresses the coil spring 3 against the biasing force of the coil spring 3. While moving to the right side. Then, when the slide member 5 is slid to the limit position where the slide movement is possible, the slide member 5 moves to the position on the rightmost side of the first storage portion 22 as shown in FIGS. Then, the operation unit 52 is in contact with the side wall 2b in the vicinity of the right side end of the opening 2e. In this case, the arms 72a and 72b of the movable contact 7 fixed to the slide member 5 are in contact with the common fixed contact 27a and the right-side fixed contact 27c, respectively. That is, since the fixed contact 27 with which the arm portions 72a and 72b of the movable contact 7 come into contact is switched from the initial state, the movement of the slide member 5 to the right side can be detected.

  11 and 12, when the operator releases the hand performing the sliding operation, the engagement piece 53 a is pushed back to the left side according to the urging force of the coil spring 3, and the slide member 5 is moved to the left. Slide to the side. When the left side end of the engagement piece 53a reaches the engagement protrusion 41 of the leaf spring 4, the engagement piece 53a is sandwiched between the engagement protrusion 41 and the coil spring 3, and the initial state (FIG. 9 and the state shown in FIG. 10) (automatic return).

  On the other hand, when the slide member 5 is slid to the left side from the initial state shown in FIGS. 9 and 10, the engagement piece 53a of the slide member 5 comes into contact with the engagement protrusion 41 of the leaf spring 4, and the plate It moves to the left side while retracting the engaging protrusion 41 toward the side wall 2a against the urging force of the spring 4. When the engagement piece 53a gets over the top of the engagement protrusion 41, the engagement protrusion 41 returns to the initial position according to the urging force of the leaf spring 4, and the slide member 5 is moved to the position shown in FIGS. It will be in the state shown in In the slide switch 1, a click feeling (moderation feeling) is generated when the leaf spring 4 is restored by the sliding operation of the slide member 5 to the left side. In this case, the slide member 5 is in a state where movement to the left side is restricted by the side wall 2b in the vicinity of the left side end of the opening 2e. That is, the slide member 5 is positioned in a state in which the slide member 5 is pressed against the side wall 2b in the vicinity of the left side end of the opening 2e by the urging force of the leaf spring 4. More specifically, the slide member 5 is held on the left side of the first storage portion 22 by the side end portion of the engagement piece 53a abutting against the engagement protrusion 41 of the leaf spring 4 in an elastic contact state. Shall be. At this time, the arm portions 72a and 72b of the movable contact 7 fixed to the slide member 5 are in contact with the left side fixed contact 27d and the common fixed contact 27a, respectively. That is, since the fixed contact 27 with which the arm portions 72a and 72b of the movable contact 7 come into contact is switched from the initial state, the movement of the slide member 5 to the left side and the locked state can be detected.

  Similarly, when the slide member 5 is slid rightward from the state shown in FIGS. 13 and 14, the engagement piece 53 a of the slide member 5 is engaged against the urging force of the leaf spring 4. The protrusion 41 moves to the right side while retracting to the side wall 2a. When the engagement piece 53a gets over the top of the engagement protrusion 41, the engagement protrusion 41 returns to the initial position according to the urging force of the leaf spring 4, and the slide member 5 is moved to the position shown in FIGS. The initial state shown in FIG. A click feeling (moderation feel) is also generated when the leaf spring 4 is returned to the initial position. In this case, the engagement piece 53a of the slide member 5 is sandwiched between the engagement protrusion 41 and the coil spring 3, and the slide member 5 returns to the initial state. At this time, the arms 72a and 72b of the movable contact 7 fixed to the slide member 5 are in contact with the common fixed contact 27a and the central fixed contact 27b, respectively. That is, since the fixed contact 27 with which the arm portions 72a and 72b of the movable contact 7 come into contact is switched from the state moved to the left side, the return of the slide member 5 to the initial state can be detected.

  Thus, in the slide switch 1 according to the present embodiment, the plate surface of the second spring storage portion 26 of the second storage portion 23 of the case 2 is such that the plate surface intersects the inner bottom surface of the second spring storage portion 26. The spring 4 is disposed, and a part of the engagement protrusion 41 of the leaf spring 4 is projected on an extension line in the compression direction of the coil spring 3. For this reason, the space for housing the leaf spring 4 is reduced, and the coil spring 3 and the engagement protrusion 41 of the leaf spring 4 are arranged so as to overlap with each other.
