Field of the Invention [0001] The present invention relates to a support mechanism for a light emitting element such as an illuminated rotary electric component, which is provided with a light emitting element such as an LED so that the operation position of the handle can be clearly identified by light from the light emitting element.

Conventionally, the support mechanism of a light emitting element has a base and a standing part provided in the holder which attaches a light emitting element, and attaches the said base to a support member, and is fitted in the hole which provided the terminal of a light emitting element in the standing part.

By the way, since the terminal of a light emitting element is long and easy to deform | transform, the support structure to the holder of the above-mentioned light emitting element has a problem that it is difficult to insert this terminal into the hole provided in the upright part of a holder, and working efficiency is bad.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described fact of the prior art, and an object thereof is to provide a support structure for a holder of a light emitting element having better work efficiency as compared with the prior art.

In order to achieve the above object, the present invention has a light emitting element having a light emitting portion and a terminal, a holder for supporting the light emitting element, and a supporting member for supporting the holder, wherein the holder has a groove for inserting a light emitting element terminal. And a restricting means for narrowing the groove in the support member.

According to the above configuration, the terminal of the light emitting element is inserted into the groove provided in the holder from above, and then the holder is simply attached to the support member, and even if there is some deformation of the terminal, it is easy to attach to the holder. When the holder is fitted to the support member, the restricting means provided on the support member acts to narrow the width of the groove, so that the strength of attachment of the terminal to the holder of the light emitting element is assured.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings by taking an example of applying the motor-driven rotary variable resistor.

In these figures, reference numeral 1 denotes a variable resistance resistor of a rotary operation type, reference numeral 2 denotes a deceleration gear mechanism, and reference numeral 3 denotes a creep mechanism. It consists of the resistor 1, the deceleration gear mechanism 2, the clutch mechanism 3, and the motor 4.

As shown in FIG. 1 and FIG. 3, the variable resistor 1 has a metal shaft number 6 having an accommodating portion 5, and a rotating operation shaft freely supported by a biaxial number 6 ( 7), a sliding support 12 arranged in the recess 11 of the rear end fixed to one end of the rotary operation shaft 7, an LED 13 serving as a light emitting element, and supporting the LED 13; It is comprised by the holder 14, The board | substrate support body 10 and the rear end side of the bearing 6 are positioned using the pin and hole provided in both.

The rotating shaft 7 has a through hole 15 at its center, and one end (rear end) of the through hole 15 is formed to a certain large diameter. In addition, a disk-shaped flange portion 16 is integrally formed at one end of the rotary operation shaft 7, and a part of the outer periphery of the flange 16 extends in parallel with the axis of the rotary operation shaft 7. Through the 17, the bow-shaped connection part 18 is formed at the same time. On the other hand, at one end (rear end) of the driving body 8, the engaging projection 20 with the split 19 is integrally formed, and the driving agent 8 and the connecting portion 18 are suitable fixing means, In other words, in the present embodiment, the pin 21 protruding from the connecting portion 18 is pushed and pushed into the hole 22 provided in the driving body 8.

The flange 8 of the driving body 8 and the rotary operation shaft 7 integrated in this way is disposed in the housing recess 5 and is provided on the stopper projection 23 formed at the bottom of the housing recess 5. As the protruding portion 17 abuts, the rotation range of the rotary operation shaft 7 is restricted.

The holder 14 has a thick base 24 at the bottom, a standing portion 26 having a thin thickness extending upward from the base 24 and a light emitting portion of the LED 13 at the thermal end of the standing portion 26. It has a cylindrical case 26a with 13a). A pair of thin V-shaped grooves 24a are formed on the upper surface of the 24, and one pair of thin grooves 26b communicate with the V-shaped grooves 24a on one surface of the standing portion 26. The lower surface of the base 24 is provided, and the attachment protrusion 24b is provided.

The support of the holder 14 of the LED is the thin groove of the V-shaped groove 24a and the standing portion 26 in which the terminal 28 is installed on the base 24 while the LED 13 is fitted to the case 26a. Then, the holder 14 is curved and the base 24 is inserted by inserting the terminal 28 into the thin portion of the V-groove 24a as shown in FIG. 15A. The pair of sidewalls 24c on both sides of the lateral side is displaced to the outside and the distance between the tip portion of the outer side 24c and the protruding protrusion 24b is reduced. Next, when the projection 24b is inserted into a pair of holes 25a provided at the bottom of the cutout portion 25 of the bearing 6 (a flat plate is provided at the tip of the projection 24b), the projection 24b is easily inserted. The distance between the distal ends of the integral protrusions 24b is forcibly widened so that the sidewalls 24c are deformed so that the V-shaped grooves 24a are narrowed, that is, the holes 25a are inward of the sidewalls 24c of the base 24. It acts as a regulatory means to be narrowed down.

Therefore, the terminal 28 is reliably fitted in the V-shaped groove 25a between the center wall 24d of the base 24 and the side wall 24c.

In this way, the thin standing portion 26 extending upward from the base 24 of the holder 14 attached to the bearing 6 is interposed with the drive body 8 of the flange portion 16 by the protrusion 17. It reaches the space 27 formed in it, and it does not interfere with the rotation operation shaft 7. In addition, as shown in FIG. 16A, the protrusions 24 of the base 24 are omitted, and the terminal 28 of the LED 13 is inserted into the V-shaped groove 24a of the base 24. As shown in (b), when the base part 24 of the holder 14 is pushed into the notch 25 of the bearing 6, the side surface 25b of this notch 25 is a side wall 24c. Is modified to narrow the V-groove 24a, i.e., the side surface 25b narrows the side wall 24c inward, thereby acting as a remedy to return to the original state, so that the terminal 28 has a base 24 Is securely fitted into the V-shaped groove 24a between the branch wall 24d and the side wall 24c.

In addition, the light emitting portion 13a fitted to the case 26a of the holder 14 is located in the inner diameter portion of the through hole 15, and the terminal 28 of the LED 13 is outward from the shaft 6; Protrude toward

The engagement 20 of the drive body 8 penetrates through the center hole 29 installed in the substrate support 10, and the engagement protrusion 20 is the center of the slide support 12. It is drilled into the installation engagement hole 30 and pushed in. A slide 31 is attached to the front surface of the slide support 12, and the slide 31 is in contact with a current collector by a resistor of the resistor plate 9.

As shown in FIG. 1, FIG. 4, and FIG. 5, at the rear end of the substrate support 10, a storage box 32 made of synthetic resin containing the deceleration gear mechanism 2 and the clutch mechanism 3 is incorporated. ) Abuts, and all of the above-mentioned bearing 6, substrate support 10, and storage box 32 are integrated so as not to be separated by a self-shaped frame 33 screwed into the motor 4. It is.

The rotating shaft 34 of the motor 4 reaches the inside of the storage box 32, and the cylindrical first worm 35 is press-fitted and fixed to the rotating shaft 34.

The first worm 35 is engaged with the cylindrical first pill 36, which is the central portion of the rotating body 37 extending in a direction orthogonal to the axis of the rotary shaft 34. It is integrally molded with

A cylindrical second worm 38 is integrally formed at one end of the rotating body 37, and the second worm 38 has a crown gear shape that is engaged with the second wall 39. The deceleration gear mechanism 2 is constituted by the worm 35, the first whirl 36, the second worm 38, and the second wall 39. In addition, both ends of the rotating body 37 are respectively supported by the side wall of the storage box 32 and the elastic side plate 40 opposite to this, and the elastic side plate 40 obliquely lowers the rotating body 37. By applying the force of elasticity in the axial direction and the direction of the second wall 39, between the first worm 35 and the first whirl 36 and between the second worm 38 and the second whirl 39 It is designed to absorb the gritty caused by the gap between the gears.

The center of the second shaft 39 is rotatably supported by the support shaft 41, and the tip of the support shaft 41 is inserted into the split 19 of the drive body 8. As shown in FIGS. 1 and 5, the axis of the rotational shaft 34 and the support shaft 41 are almost in line, i.e., the rotation of the rotational shaft 34 of the motor 4 and the variable resistor 1 It is arrange | positioned substantially in line with the operation shaft 7.

6 to 8, an annular fin groove 42 is formed in the vicinity of the outer circumference of the second churn 39, and the fin groove 42 is an annular clutch plate ( 43) This rotating free path is fitted. The clutch plate 43 is provided with a plurality of locking projections 44 at equal intervals in the same direction, and the locking holes 46 of the leaf springs 45 are caught by some of these locking projections 44. .

The leaf spring 45 has a plurality of arms 47 extending radially, and the engaging holes 46 are bored in the distal ends of the cross bars 47, respectively. In the center of the leaf spring 45, a disk-shaped support 48 is molded in the outsert, and the support shaft 41 is pushed into the fitting hole 49 in the center of the support 48, By holding the pair of hook pieces 50 formed in the center of the leaf spring 45 on the main surface of the support shaft 41, both the support shaft 41, the leaf spring 45, and the support body 48 are integrated. And the clutch mechanism 3 is comprised by the four members of the leaf | plate spring 45 and the clutch plate 43 which have the 2nd wheel 39, the support shaft 41, and the support body 48. As shown in FIG.

When assembling the clutch mechanism 3 configured as described above, first, the clutch plate 43 is inserted into the groove 42 of the second wheel 39, and at the rear end of the second wheel 39, the support shaft ( 4l) is inserted, and then the fitting hole 49 of the support member 48 is pushed into the front end of the support shaft 41, and the respective engaging holes 46 of the leaf spring 45 are inserted into the clutch plate 43. Insert into the locking projection (44). At this time, since the length between each of the engaging holes 46 is set to an integral multiple of the length between the engaging projections 44 (in this embodiment, twice), the leaf spring can be selected by appropriately selecting the plurality of engaging projections 44. The 45 can be easily connected to the clutch plate 43. In addition, when the support body 48 is inserted into the support shaft 41, both locking pieces 50 are automatically caught around the support shaft 41, so that the support member 48 can be prevented from falling off from the support shaft 4l. Can be. Then, when the clutch mechanism 3 is assembled in this manner, the clutch plate 33 has a force in the direction in which the clutch plate 33 is pressed against the second wheel 39 by the elastic force at each arm 47 bent to the leaf spring 45. Is added. In this case, since the span of each arm 47 is set long enough, necessary sufficient frictional force can be provided between the 2nd wheel 39 and the clutch plate 43, and each arm 47 Since is formed in the symmetrical form, the elastic force can be imparted to the clutch plate 43 in the leaf spring 45 in a good balance.

Next, the operation of the motor-driven variable resistor configured as described above will be described. First, the case where the variable resistor 1 is operated by the driving force of the motor 4 will be described. In this case, the rotational force of the motor 4 includes the first worm 35 fixed to the rotary shaft 34, the first whirl 36 engaged with the first worm 35, and the first whirl 36. The second worm 38 is engaged with the second worm 38 via the second worm 38 which rotates integrally with the second worm 38, and the speed of the rotational shaft 34 is decelerated therebetween. In this way, when the second whirl 39 rotates at a low speed, the clutch plate 43 fitted to the groove 42 of the second whirl 39 rotates integrally with the second whirl 39 by frictional force between them. Since the leaf spring 45 connected to the clutch plate 43 and the support shaft 41 fixed to the support 48 of the leaf spring 45 also rotate integrally with the second circle 39, the support shaft ( The driving agent 8 connected to 41 also rotates in conjunction with the second whirl 39. That is, in this case, the clutch mechanism 3 is in a connected state, and the rotational force of the motor 4 is transmitted to the drive body 8 of the variable resistor 1 through the deceleration gear mechanism 2 and the clutch mechanism 3. . In this way, when the drive body 8 rotates by the driving force of the motor 4, the slide support 12 press-fitted to the engaging protrusion 20 of the drive body 8 rotates with respect to the resistor plate 9, The resistance value is adjusted in response to a change in the relative position between the slider 3l of the slide support 12 and the resistor of the resistor plate 9.

In addition, when the drive body 8 rotates, the rotation operation shaft 7 also rotates in association with it, but the rotation operation shaft 7 is in a range in which the protruding portion 17 abuts against both ends of the stopper projection 23. Only rotation is possible, and the LED 13 and the holder 14 do not collide in this range. Therefore, when power is supplied to the LED 13 through the terminal 28, and the light emitting portion of the LED 13 emits light, the light reaches the outside through the through hole 15 of the rotary operation shaft 7 For example, the display portion of a knob (not shown) mounted on the tip of the rotary operation shaft 7 can be dimmed.

On the other hand, when the rotary operation shaft 7 is operated manually by stopping the motor 4. The rotational force of the rotary operation shaft 7 is transmitted to the slide support 12 through the drive body 8, and the resistance value is adjusted by the rotation of the slide support 12. As shown in FIG. Moreover, when the drive body 8 rotates, the rotational force is transmitted to the clutch plate 43 through the support shaft 41, the support body 48, and the leaf spring 45, but the clutch plate 43 and the second wheel The clutch mechanism 3 is in a shut-off state without slipping between the parts 39 and being not transmitted to the second whirl 39.

In addition, when the LED 13 emits light during such manual operation, the light reaches the outside of the rotary operation shaft 7 through the through hole 15, and thus not shown as in the case of the motor driving described above. The display can be dimmed.

As described above, in the above embodiment, the supporting structure of the LED 13 to the holder 14 is the base portion 28 of the terminal 28 in a state in which the light emitting portion 13a of the LED 13 is fitted to the case 26a. After inserting into the V-shaped groove 24a provided in the 24 and the fine groove 26b of the standing part 26, the projection 24b provided in the lower surface of the base 24 is cut out part 25 of the bearing 6 Since it is supported by being pushed into the hole 25a provided in), even if the terminal 28 changes somewhat, the support to the holder 14 is easy, and work efficiency improves compared with the former. When the terminal 28 is inserted into the V-shaped 24a of the base 24, the side walls 24c on both sides of the base 24 are displaced outward, but the protrusions 24B on the bottom surface of the base 24 are Is pushed into the hole 25a provided in the notch 25 of the bearing 6, the side wall 24c returns to its original state, so that the end of the terminal 28 is reliably supported by the V-shaped groove 24a. .

According to the present invention, since the terminal of the light emitting element can be simply inserted from above into the groove provided in the base and the standing portion of the holder, it can be easily inserted into the groove even if the terminal is bent slightly. Compared to the work efficiency is good. Moreover, since the regulating means which narrows the width | variety of the groove | channel into which the terminal was inserted is provided in the support member of a holder, support of a terminal is also sure.
