    Multi-manipulation electric parts {MULTIOPERATIVE ELECTRIC PARTS}
    [16] The present invention relates to, for example, a complex operation type electric part provided in a video camera, a mobile phone, and the like, and outputting an electric signal by two different operations such as a rotation operation or a slide operation and a press-in operation.
    [17] Background Art [0002] Conventionally, in mobile phones and the like, rotary switches, which are rotary operation type electric parts, and tact switches, which are press-fit operation type electric parts, are separately installed separately from each other. It is known to select, and set, for example, a call mode by the second electric signal output from the tact switch to automatically dial the selected telephone number.
    [18] However, in the above-described prior art, the rotary operation type electrical parts (rotary switch) and the press-operation type electric parts (tact switch) are separately installed, so that the storage space increases when these two electric parts are installed in parallel. There was. In addition, there is a problem in that the operability is poor because the operation of the tact switch must be press-in operation by moving the finger after rotating the operation body of the rotary switch with a finger at the user's discretion.
    [19] According to the present invention, the operating body is fixed to the wafer to be rotatable (or slideable) and press-fitted, the winding of the torsion coil spring is wound around the operation body, and both arm portions of the torsion coil spring are elastically contacted with the wafer. Thus, when both arm portions of the torsion coil spring wound on the operating body are elastically contacted with the wafer, one arm portion of the torsion coil spring is bent during rotation or slide operation of the operating body to give the operating body a return force to the center position. During the press-fit operation, the arm parts on both sides of the torsion coil spring are bent to give the operating body a return force to the center position, so that two different operations such as rotation or slide operation and press-fit operation can be performed by one operating body.

    [20] In the composite operation type electrical component of the present invention, a wafer having fixed contacts for rotation detection and press-fit detection, an operating body rotatably and press-fitted to the wafer, and installed on the operating body, A movable contact that can be connected / disconnected, and a torsion coil spring for center return from which the pair of arms protrude from both ends of the winding portion; and winding both winding portions of the torsion coil spring to the operating body and simultaneously with both arm portions of the torsion coil spring. Each of them is in elastic contact with the wafer.
    [21] In order to prevent the misoperation of the operating body, projections may be provided on either the wafer or the operating body, and on the other side, a concave portion capable of accommodating the projections at the center position of the operating body may be provided. Press-in operation during rotation operation or rotation operation during press-in operation is regulated.
    [22] In the composite operation type electrical component of the present invention, a wafer having fixed contacts for slide detection and press-fit detection, an operating body slidably and slidably fixed to the wafer, and provided on the operating body, the fixed contact point And a movable contact which can be connected to or detached from the arm, and a torsion coil spring for returning to the center, in which a pair of arms protrude from both ends of the winding part, and winding both winding parts of the torsion coil spring to the operating body and at the same time Each part is elastically contacted with the wafer, and either one of the wafer and the operating body is provided with a guide groove extending in the slide direction and the press-in direction of the operating body, and the other side is provided with a projection engaging with the guide groove. .
    [23] If the fixed side click portion is provided on either the wafer or the cover member covered with the wafer, and the movable side click portion is provided on at least one of the operating body, the torsion coil spring and the movable contact, the operating body is press-fitted. In this case, since the movable side click portion is displaced from the fixed side click portion, a feeling of click (theft) is generated, so that there is no need to separately install a member for producing a click feeling, thereby reducing costs.

A plane 9a perpendicular to the plane is formed. Moreover, the inner bottom face part 7 has the rotation detection fixed contact 10 and 11 formed along the rotation direction of the operating body 2, and the depth side of a press-in direction with respect to these fixed contacts 10 and 11 (FIG. 6).

The fixed stationary contact 13 is integrally molded. These fixed contacts 10 to 13 protrude laterally from the wall portion 8 of the wafer 1 as the external terminals 10a to 13a, respectively. The immediately preceding side of the wall portion 8 in the pressing direction is formed in an arc shape with the support shaft 9 as the center, and an end portion 14 is formed in the arc portion. This end portion 14 defines the rotation range of the operating body 2, and a recessed portion 15 is formed in the central portion of the end portion 14. Moreover, the installation hole 16 is provided in the depth side (lower side of FIG. 6) of the wall part 8 in the pushing direction.
    [28] The operating body 2 is integrally formed in a left-right symmetrical shape, as shown in FIG. 4, a base 17 provided in the wafer 1, an operation unit 18 protruding from the wafer 1, It has a connection part 19 which connects these base 17 and the operation part 18, and the connection part 19 is inserted in the edge part 14 of the wafer 1, and is made to pass. A cylindrical boss 21 is placed upright in the center of the base 17, and the long hole 20 provided in the boss 21 extends in the pressing direction of the operating body 2, and this long hole 20 is provided. ), The support shaft 9 is fitted through. Moreover, the annular groove 17a is formed around this long hole 20, and the pair of engagement grooves 22 and 23 are formed obliquely upward from this annular groove 17a, respectively. As shown in FIG. 1, the winding portion 4a of the torsion coil spring 4 is wound around the boss 21 and positioned in the annular groove 17a. Both arm portions 4b and 4c are engaged grooves 22 and 23. ) And is engaged with the engaging end portions 8a and 8b of the wafer 1. Further, a plane 20a perpendicular to the longitudinal direction of the long hole 20 is formed just in front of the long hole 20 in the press-in direction, and the non-operation or view of the operating body 2 shown in FIG. In the rotation operation shown in Fig. 2, the plane 20a of the long hole 20 and the plane 9a of the support shaft 9 are kept apart, while in the press-in operation of the operating body 2 shown in Fig. 3. The plane 20a and the plane 9a are in contact with each other.
    [29] The said operation part 18 is formed in circular arc shape centering on the base 17, and the processus | protrusion 24 is formed in the inner side of this operation part 18 center. In the rotation operation of the operating body 2 shown in FIG. 2, the protrusion 24 moves outside the end portion 14 of the wafer 1, but is press-fitted at the center position of the operating body 2 shown in FIG. 3. At the time of operation, the protrusion 24 moves inside the recessed portion 15 of the wafer 1.
    [30] The sliding member 3 has a pair of mounting portions 25 and 26 provided on the lower surface of the base 17 and a pair of sliding portions 27 and 28 formed between these mounting portions 25 and 26, These are integrally formed in a left-right symmetrical shape. The movable contacts 27a and 28a which protrude downward are formed in the center of each sliding part 27 and 28, respectively, and one movable contact 28a is always in contact with the said common fixed contact 13 at all times. In addition, in order to facilitate the explanation of the relative positions of the movable contacts 27a and 28a in FIGS. 1 to 3, the movable contacts 27a and 28a are shown as ellipses and circles hatched therein, respectively, and at the same time, the fixed contacts. 10 to 13 and external terminals 10a to 13a are indicated by double-dotted lines, respectively.
    [31] A plurality of locking portions 29 are formed in the cover member 6, and these locking portions 29 are inserted along the wall portion 8 of the wafer 1, and the tip ends thereof are bent to form the wafer 1. By stopping the lower surface, the upper opening 1a of the wafer 1 is covered by the lid member 6, as shown in FIG.
    [32] In the first embodiment, both arm portions 4b and 4c of the torsion coil spring 4 engage the end portions 8a and 8b of the wafer 1 at the time of non-operation of the operating body 2 shown in FIG. And the winding portion 4a is wound around the boss 21 of the operating body 2, so that the return force from the torsion coil spring 4 to the center position is applied to the operating body 2, respectively. . At this time, the projection 24 of the operating body 2 faces the concave portion 15 of the wafer 1 and at the same time the plane 20a and the support shaft 9 of the long hole 20 of the operating body 2. The movable contact 28a of the perturbator 3 is always in contact with the common fixed contact 13, while the other movable contact 27a is connected to the other fixed contacts 10 to 12. ), The rotary switch and the push switch are both off.
    [33] When the operation part 18 of the operating body 2 is rotated counterclockwise in this state, as shown in FIG. 2, the sliding body 3 also interlocks with the operating body 2, and centers on the support shaft 9 as shown in FIG. And the movable contact 27a of the sliding member 3 is in contact with one of the fixed contacts 11 for rotation detection, so that the external terminal 11a and the common external terminal 13a are conductive. Only the rotary switch is turned on to output the first electrical signal. At this time, one arm portion 4b of the torsion coil spring 4 is locked to the engagement end portion 8a of the wafer 1, while the other arm portion 4c is an engagement groove (of the operating body 2). Since the arm portions 4b and 4c are compressed in the closing direction because they are compressed in the rotational direction by the end of 23 and are separated from the engagement end 8b, the return force to the center position with respect to the operating body 2 is reduced. Is given. When the operation unit 18 is placed, the operation body 2 rotates clockwise by the force of the torsion coil spring 4 and automatically returns to the center position shown in FIG. 1, and the movable contact 27a is used for rotation detection. The rotary switch is turned off again because it is separated from the fixed contact 11. In addition, during the rotation operation of the operating body 2, the projection 24 moves away from the concave portion 15 to the outside of the end portion 14, so that a force in the press-fitting direction is inadvertently applied during the rotation operation of the operating body 2. Even if the projections 24 are in contact with the end 14 and cannot press the operating body 2, it is possible to prevent the wrong operation of the operating body 2.
    [34] Similarly, when the operating body 2 is rotated in the clockwise direction, the movable contact 28a of the sliding member 3 is always in contact with the common fixed contact 13 and the other movable contact 27a is for rotation detection. The external terminal 10a and the common external terminal 13a are brought into contact with the other stationary contact 10, and only the rotary switch is turned on to output the first electrical signal.
    [35] Moreover, when the operation part 18 is press-fitted in the direction of the wafer 1 from the non-operation state of the operation body 2 shown in FIG. 1, as shown in FIG. 3, the operation body 2 and the sliding member 3 will be pressed. It moves integrally in the longitudinal direction of the long hole 20. As a result, the click plate 5 is pressed against the base 17 and buckled, so that a feeling of click (theft) is generated and the movable contact 27a of the sliding member 3 contacts the fixed contact 12 for indentation detection. Therefore, the external terminal 12a and the common external terminal 13a are turned on, and only the push switch is turned on to output the second electric signal. At this time, both arm portions 4b and 4c of the torsion coil spring 4 are stopped by the engagement ends 8a and 8b of the wafer 1, but the winding portion 4a is the boss of the operating body 2. Since the arm 21 moves in the pressing direction, the arm portions 4b and 4c are compressed in the closing direction to impart a return force to the center position with respect to the operating body 2. When the operation unit 18 is placed, the operation body 2 rises due to the force of the torsion coil spring 4, and automatically returns to the center position shown in FIG. 1, and the movable contact 27a is a fixed contact for indentation detection. Off from (12), the push switch is turned off again. In addition, since the projection 24 during the press-in operation of the operating body 2 moves inside the recessed part 15, the protrusions 24 may operate even when a force in the rotational direction is inadvertently applied during the press-in operation of the operating body 2. Since the operating body 2 cannot be rotated in contact with the wall surfaces of the recesses 15, the misoperation of the operating body 2 can be prevented in this case as well.
    [36] Fig. 7 is a perspective view of the composite operation type electrical component according to the second embodiment, and Fig. 8 is an exploded perspective view of the composite operation type electrical component. As shown in FIG. 8, the composite operation type electric part of the present embodiment has a wafer 31 made of synthetic resin having an upper opening 30, and an operating member 32 slidably and slidably fixed to the wafer 31. As shown in FIG. And a torsion coil spring in which the sliding element 33 made of a conductive elastic plate fixed to the lower surface of the operating body 32 and the pair of arm portions 34b and 34c protrude from both ends of the central winding portion 34a. 34 and the cover member 35 which covers the upper opening 30 of the wafer 31 are mainly comprised.
    [37] The wafer 31 has a rectangular inner bottom portion 36, which includes a guide groove 37 extending in the slide direction of the operating body 32, the guide groove 37 and Two different guide grooves 38a and 38b are formed orthogonally extending in the pressing direction of the operating body 32. An end portion 39 is formed at the front side of the wafer 31 in the slide direction, and the end portion 39 defines a slide range of the operating body 32, and a torsion coil spring 34 is provided at both ends of the end portion 39. Locking portions 40, 41 for stopping the arm portions 34b and 34c of the < Desc / Clms Page number 6 > In addition, the inner bottom surface portion 36 of the wafer 31 has slide detection fixed contacts 42 and 43 positioned respectively at the upper and lower portions (both sides of the slide direction) of FIG. 7 and the right side (the pressing direction) of FIG. The fixed contact 44 for press-fit detection located on the inner side of the side) and the fixed contact 45 which is formed along the slide direction and the press-in direction of the operating body 32, and which the sliding member 33 always contacts. These fixed contacts 42 to 45 protrude to the side of the wafer 31 as the external terminals 42a and 45a, respectively.
    [38] The operating body 32 is formed integrally with the base 46 positioned in the wafer 31 and the operating portion 47 protruding from the end 39 of the wafer 31. The projection 48 is installed in the center of the upper surface of the base 46, and a pair of wall portions 49 and 50 are formed at both sides of the upper surface of the base 46. As shown in Fig. 7, the winding portion 34a of the torsion coil spring 34 is wound around the projection 48, and both arm portions 34b and 34c are suspended from the wall portions 49 and 50, respectively. A pair of projections 51 and 52 are formed on the lower surface of the base 46, and these projections 51 and 52 engage with the guide groove 37 and the other guide groove 38a.
    [39] The sliding member 33 is provided with a mounting portion 53 installed on the lower surface of the base 46, a pair of movable contacts 54 and 55 extending from one side of the mounting portion 53, and a pair of extension portions extending to the other side. It consists of movable contacts 56 and 57, and is integrally formed in left-right symmetry shape, and among these, the movable contact 57 is always in contact with the said common fixed contact 45 at all times.
    [40] The cover member 35 is provided with a pair of locking portions 58. The upper openings 30 of the wafer 31 are snapped by inserting the locking portions 58 along the side surfaces of the wafer 31. The cover member 35 is covered.
    [41] In this second embodiment, both arm portions 34b and 34c of the torsion coil spring 34 are engaged portions 40 and 41 of the wafer 31 at the time of non-operation of the operating body 32 shown in FIG. And the windings 34a are wound around the projections 48 of the operating body 32, so that the return force from the torsion coil spring 34 to the center position is applied to the operating body 32. . At this time, the projection 51 of the operating body 32 engages with the guide groove 37 and is located on the extension line of the other guide groove 38a, and similarly, the other projection 52 engages with the guide groove 37 as well. At the same time it is located on the extension line of the other guide groove (38b). Since the movable contact 57 of the sliding member 33 is always in contact with the common fixed contact 45, the other movable contacts 54 to 56 are not in contact with the other fixed contacts 42 to 44. The slide switch and push switch are both off.
    [42] In this state, when the operation part 47 of the operating body 32 is slid to the lower side of FIG. 7, the sliding member 33 also slides in association with the operating body 32, and the movable contact of this sliding member 33 ( The external terminal 43a and the common external terminal 45a are conducted because 57 is always in contact with the common fixed contact 45 and the other movable contact 54 is in contact with the slide detecting fixed contact 43. Only the slide switch is turned on to output the first electrical signal. At this time, one arm portion 34b of the torsion coil spring 34 is stopped by the locking portion 40 of the wafer 31, while the other arm portion 34c is the wall portion 50 of the operating body 32. By pressing in the slide direction and falling away from the locking portion 41, the two arm portions 34b and 34c are compressed in the closing direction to impart a return force to the center position with respect to the operating body 32. Moreover, when the operation part 47 of the operating body 32 is released, the operating body 32 will slide upward of FIG. 7 by the force of the torsion coil spring 34, and will return to center position automatically, and the movable contact 54 The slide switch is turned off again because it is separated from the fixed contact 43 for slide detection. In addition, during the slide operation of the operating body 32, both projections 51 and 52 of the operating body 32 move in the slide direction along the guide groove 37 on one side. Therefore, even when a force in the pressing direction is applied, the two projections 51 and 52 cannot be pushed along the other guide grooves 38a and 38b, thereby preventing the wrong operation of the operating body 32.
    [43] Similarly, when the operating body 32 is operated by sliding upwards in FIG. 7, the movable contact 57 of the slider 33 is always in contact with the common fixed contact 45 and the other movable contact 56 slides. Since the external contact 42a and the common external terminal 45a become conductive because of contact with the other fixed contact 42 for detection, only the slide switch is turned on and the first electric signal is output.
    [44] Moreover, when the operating body 32 is in the center position shown in FIG. 7, when the operating part 47 of this operating body 32 is pushed to the right direction of FIG. 7, the projections 51 and 52 of the operating body 32 will be carried out. Moves in the pressing direction along the guide grooves 38a and 38b, respectively. Accordingly, since the movable contact 55 of the sliding member 33 contacts the fixed contact 44 for press-fit detection, the external terminal 44a and the common external terminal 45a become conductive, and only the push switch is turned on. And the second electrical signal is output. At this time, both arm portions 34b and 34c of the torsion coil spring 34 are stopped by the locking portions 40 and 41 of the wafer 31, but the winding portion 34a is a projection (34) of the operating body 32. 48 is pressed in the right direction of FIG. 7, the two arm portions 34b and 34c are compressed in the closing direction to impart a return force to the center position with respect to the operating body 32. Moreover, when the operation part 47 of the operating body 32 is released, the operating body 32 will move to the left direction of FIG. 7 by the force of the torsion coil spring 34, and will return to a center position automatically, and the movable contact 55 () Is separated from the press-fit detection fixed contact 44, the push switch is turned off again. In addition, since both projections 51 and 52 of the operating body 32 move in the pressing direction along the guide grooves 38a and 38b during the press-in operation of the operating body 32, it is wrong during the press-in operation of the operating body 32. Therefore, even if the force in the slide direction can not slide both projections (51, 52) along the other guide groove 37, in this case, it is possible to prevent the wrong operation of the operating body (32).
    [45] FIG. 9 is a perspective view of a composite manipulation type electric component according to a third embodiment, FIG. 10 is a plan view showing the cover member removed from the composite manipulation type electric component, and FIG. 11 is a click mechanism provided in the composite manipulation type electric component. It is a sectional drawing of main part, The same code | symbol is attached | subjected to the part corresponding to FIGS.
    [46] The composite operation type electrical part of this embodiment constitutes the click mechanism by the operating body 2 and the lid member 6, instead of using the click plate 5 of the first embodiment described above. That is, the cover member 6 is formed with two beam-shaped deformation parts 61 by the slit 60, and the first projection 62 as the fixed side click part is formed at the center of the deformation part 61. Formed. On the other hand, the base 17 of the operating body 2 is provided with a second projection 63 as a movable side click portion, and the second projection 63 faces the rear surface of the lid member 6. In addition, since the structure and operation | movement other than this click mechanism are fundamentally the same as the composite operation type electric component of 1st Embodiment, the overlapping description is abbreviate | omitted here.
    [47] In the third embodiment configured as described above, when the operation unit 18 of the operating body 2 is press-fitted in the direction of the wafer 1 from the non-operational state shown in FIG. 10, the operating body 2 as shown by the arrow in FIG. 11. ) Moves in the longitudinal direction of the long hole 20. Thereby, the 2nd protrusion 63 formed in the base 17 of the operating body 2 moves the back surface of the deformation | transformation part 61 formed in the cover member 6 in the direction shown by the dashed-dotted line, and the 2nd A click feeling occurs as the projection 63 rides over the first projection 62. Therefore, the click plate 5 becomes unnecessary, whereby the number of parts can be reduced, and the assembly workability can be improved. In addition, the size of the first protrusion 62 or the second protrusion 63 may be changed to change the size of the click feeling so that, for example, the width of the first protrusion 62 is increased so that the width of the first protrusion 62 and the second protrusion 63 are increased. When the contact area is increased, a stronger click feeling can be generated, and when the operating body 2 is rotated from the center position, the operating body 2 can be restrained from being pressed in by mistake.
    [48] In the third embodiment, the first projection 62 as the fixed side click portion is formed on the lid member 6, and the second projection 63 as the movable side click portion is formed on the base 17 of the operating body 2. Although the case where the click mechanism was comprised by these 1st protrusion 62 and the 2nd protrusion 63 was demonstrated, although the fixed side click part and the movable side click part are formed in another member as described below, it is the same. Can have an effect.
    [49] In the embodiment shown in Fig. 12, the projection 64 serving as the fixed side click portion is formed on the inner bottom face 7 of the wafer 1 and the winding portion 4a of the torsion coil spring 4 is moved to the movable side click portion. It is also used as a conduit, and the projection 64 is faced in the hole 64 opened in the base 17 of the operating body 2. Therefore, in the non-operational state shown in FIG. 12, when the operation part 18 of the operating body 2 is press-fitted in the direction of the wafer 1, the winding part which moves integrally with the boss 21 of the operating body 2 ( As 4a) rides over the projection 64, a feeling of click is generated.
    [50] In the embodiment shown in FIG. 13, the torsion coil spring 4 which is used as the fixed side click portion is also used as one engagement end portion 8b formed on the wall portion 8 of the wafer 1 and fixed to the engagement end portion 8b. The projection 65 is formed in the arm part 4c of (). In this case, the torsion coil spring 4 is assembled in an inclined state with respect to the press-in direction of the operating body 2, and is operated by the arm part 4b held by the engagement end 8a at an almost horizontal angle. Sieve 2 is given a return force to the center position. Therefore, when the operation part 18 of the operating body 2 is press-fitted in the direction of the wafer 1 in the non-operational state shown in FIG. 13, the projection 65 of the arm part 4c which moves integrally with the operating body 2 will be carried out. ) Passes over the engagement end 8b to generate a feeling of click.
    [51] In the embodiment shown in Fig. 14, the first projection 66 as the fixed side click portion is formed on the inner bottom face 7 of the wafer 1, and the second projection as the movable side click portion on the sliding member 3 67). The second protrusion 67 is a dummy contact which is in elastic contact with the inner bottom face 7 of the wafer 1 but is not involved in the switching operation of the switch. Therefore, when the operation part 18 of the operating body 2 is press-fitted in the direction of the wafer 1 in the non-operational state shown in FIG. 14, the 2nd protrusion of the sliding member 3 which moves integrally with the operating body 2 will be carried out. A feeling of click is created when the 67 passes over the first protrusion 66 of the wafer 1.
    [52] In the embodiment shown in Fig. 15, the projection 68 as the fixed side click portion is formed on the cover member 6, and the winding portion 4a of the torsion coil spring 4 is also used as the movable side click portion. Therefore, in the non-operational state shown in FIG. 15, when the operation part 18 of the operating body 2 is press-fitted in the direction of the wafer 1, the winding part 4a which moves integrally with the boss 21 of the operating body 2 ) Rides through the projection 68, a feeling of click is created.
    [53] Further, the click mechanism shown in the third embodiment or FIGS. 12 to 15 can also be applied to a composite operation type electrical component which performs the slide operation and the press-in operation described in the second embodiment.
    [54] This invention is implemented in the form as described above, and has the effect as described below.
    [55] Rotating and press-fitting the operating body on the wafer to wind the winding part of the torsion coil spring on the operation body and at the same time elastically contact both arms of the torsion coil spring to the wafer to operate two different operations of rotation and indentation. It can be carried out in a sieve, and the number of parts can be reduced, and the size can be reduced.
    [56] In addition, by providing a projection on one of the wafer and the operating body, and providing a recess in the other side to accommodate the projection at the center position of the operating body, the press-in operation during the rotation operation of the operation body and the rotation operation during the press-in operation are performed. Since it is regulated, misoperation of an operating body can be prevented.
    [57] In addition, the operation body is slidably and press-fitted to the wafer to wind the winding portion of the torsion coil spring to the operation body, and at the same time, the two arm operations of the torsion coil spring are elastically contacted with the wafer to perform two different operations such as slide and indentation. It can be performed by the operating body, and the number of parts can be reduced, and the size can be reduced. In addition, a guide groove extending in the slide direction and the pressing direction of the operating body is provided on one of the wafer and the operating body, and projections engaged with the guide groove are provided on the other side, so that the operation is performed during the slide operation or the pressing operation. Since the movement of the sieve is smooth along the guide groove, the press-in operation during the slide operation of the operating body or the slide operation during the press-in operation is regulated, and therefore, the misoperation of the operating body can be prevented.
    [58] If the fixed side click portion is provided on either the wafer and the cover member covered with the wafer, and the movable side click portion is provided on at least one of the operating body, the torsion coil spring and the movable contact, the operating body is press-fitted. In this case, since the movable click portion is displaced from the fixed click portion, a click (theft) feeling is generated, so that there is no need to separately provide a member for producing a click feeling, thereby reducing costs.
