The case 1 is a thermosetting synthetic resin (for example, melamine phenol resin) formed of a rectangular body having an open front surface, and an elastic synthetic resin (for example, polybutylene terephthalate). Resin = PBT resin), which is formed by joining the cover 20 formed in a rectangular shape with an open rear surface.

The assembling tank 11 protrudes from the upper and lower (upper and lower side of FIG. 3) longitudinal direction of the body 10, and is provided. On the other hand, the upper and lower end portions of the cover 20 are respectively provided with a shoulder portion 21 protrudes, respectively, the assembled pieces 22 toward the body 10 from the trailing edge of each shoulder portion 21, respectively. This protrusion is installed. In each assembly piece 22, an engagement hole 22a is formed in which the assembly tank 11 provided in the body 10 engages with the unevenness. An inclined guide surface 11a is formed at the front end of the assembly tank 11 so as to reduce the amount of protrusion from the body 10 as the front side thereof. Therefore, when assembling and attaching the cover 20 to the body 10, the assembly piece 22 is bent along the guide surface 11a, and finally, the assembling holes 22a provided in the assembly piece 22 are assembled. The body 10 and the cover 20 are coupled by fitting to the jaw 11. Since the assembly piece 22 needs to be bent in this way, the cover 20 is formed from the synthetic resin which has an elastic body.

Here, since the flow of resin is formed at the time of shaping the granulated piece 22, and it joins in the vicinity of the front end of the granulated piece 22, the weld line is easy to be formed in the front end of the granulated piece 22. As shown in FIG. Since the granulated piece 22 engages with the granulation tank 11 using curvature as mentioned above, when a weld line is formed, it will become easy to bend when it bends. Therefore, in this embodiment, the reinforcement part 22b which enlarged thickness is formed in the part in which the weld line is formed, and the granulation piece 22 is prevented from being broken. Moreover, the reinforcing piece 22c is extended forward from the trailing edge of the engaging hole 22a. The assembly tank 11 provided in the body 10 is formed in the form of two legs at the rear end so as to engage with the reinforcing piece 22b. Therefore, the thick reinforcement part 22b is formed also in the reinforcement piece 22c, and the crack of the granulated piece 22 by formation of a weld line can be prevented more reliably.

In addition, the shape of the engagement hole 22a is not limited to the said shape, For example, as shown in FIG. 13, you may form two engagement holes 22a in the assembly piece 22, In this case, In the body 10, two assembly tanks 11 may be protruded on each of the upper and lower end faces. Further, as shown in Fig. 14, a rectangular engagement hole 22a may be formed.

The body 10 is divided into two compartments, the terminal storage chamber 13 and the circuit storage chamber 14, by partition walls 12 provided in the middle portion of the longitudinal direction. In place of the circumferential wall of the body 10, 10 d of crisis determination protrusions which protrude forward are provided, and the positioning recessed part 10c is formed. As a result, in the present embodiment, when the body 10 and the cover 20 are engaged, the positioning protrusion 10d engages with the concave portion 20d formed on the main wall of the cover 20, and at the same time, the position Since the protrusions (not shown) projecting rearward from the circumferential wall of the cover 20 engage with the crystal concave portion 10c, the shaking of the cover 20 with respect to the body 10 can be prevented, In addition, the impact resistance against falling can be improved. Further, H ₁ ≠ if a substantially distance to the upper and lower stepped portions of the positioning protrusions (10d) from the central position in the length direction of the body 10.

In the terminal storage chamber 13 formed through the partition wall 12 in the body 10, a pair of terminals 30 serving as fastening terminals are incorporated. The terminal 30 is composed of a terminal plate 35 and a locking spring 36, and the locking spring 36 is disposed between the terminal plate 35 and the locking spring 36. And a clamping piece 36b which does not dig into the electric wire inserted into the electric wire insertion hole 15 (refer to FIG. 5 and FIG. 6), and the contact piece 36a which is in close contact with the electric wire. That is, the wire insertion opening 15 is formed in the rear wall of the body 10 so that an electric wire can be introduce | transduced between the locking spring 36 and the terminal piece 35. As shown in FIG. When the electric wire is inserted between the locking spring 36 and the terminal plate 35 through the wire insertion hole 15 on the side of the clamping piece 36B, the spring of the contact piece 36a and the clamping piece 36b is inserted. The electric wire is clamped between the terminal plate 35 by the force, and the chain clamping piece 36b can not be pulled out by digging into the electric wire. In this way, the connection can be made simply by inserting the electric wire into the electric wire insertion port 15, so that the wiring work becomes easier as compared with the case of using a screwed terminal or the like.

In addition, the terminal storage chamber 13 is provided with a release button 37 made of a thermosetting resin (for example, urea resin) so as to span both locking springs 36. The release button 37 abuts against the clamping piece 36b of both locking springs 36, and the portion where the release button 37 abuts against the clamping piece 36b is the terminal piece. It is staggered from the site | part which clamps an electric wire between 35 and a support. Here, in this embodiment, since the insulation piece 37a protrudes integrally from the middle part of the release button 37 forward so that one part of the release button 37 may be interposed between the both terminals 30, The electric wire inserted from the electric wire insertion port 15 can be prevented from contacting the corresponding terminal 30 and the other terminal 30, and the insulation between both terminals 30 can be improved. In addition, an operation hole 16 (see Fig. 5) is formed in the rear wall of the body 10 at a portion corresponding to the release button 37, and a tip such as a negative driver is inserted into the operation hole 16 to release the release button. By pressing (37), the clasp crystal piece 36b, which is dug into the wire, is bent in the pressure-contact release direction from the wire so that the wire can be pulled out. Moreover, the connecting piece 35a for mounting on the 1st printed board 51 mentioned later is provided in the terminal board 35 by protrusion.

In the circuit storage chamber 14, a choke coil L, a second printed plate 52, a heat sink 40, and the like, which are mounted on the first printed board 51, are incorporated. Here, each of the printing plates 51 and 52 constitutes a printing plate block 50, and the first printing plate 51 and the second printing plate 52 have a plurality of lead wires 57 (see FIG. 6). Is electrically connected to the first printed plate 51, and the connecting piece 35a of the terminal plate 35 described above is inserted into the connecting hole 51b and soldered thereto. The circuit part shown in FIG. 7 is comprised. Between both terminals 30, a series load of an illumination load (not shown), such as an incandescent lamp, and a commercial power supply (not shown) is connected by the above-mentioned electric wire.

In addition, a serial circuit between a triac Q ₁ as a power control element and a choke coil L constituting a noise filter is inserted between both terminals 30 through a micro switch SW described later. The condenser C ₁ constituting the noise filter together with the choke coil L is connected in parallel. A series circuit of a capacitor C ₂ , a volume VR and a resistor R ₁ is connected in parallel to the triac Q ₁ , and a zener diode ZD ₁ is connected to a series circuit of the capacitor C ₂ and the volume VR. , ZD ₂ ) is connected to the series circuit. In addition, between the connection point between the capacitor C ₂ and the volume VR and the triac Q ₁ , a die liquid Q ₂ as a trigger element is inserted, and the potential of the connection point is the die liquid Q _2. The triac Q ₁ is triggered and turned on when the breakover voltage of Once on, the triac Q ₁ remains on until the voltage waveform of the commercial power source reaches the zero cross point. That is, it is triggered by the die solution Q ₂ every half cycle of the voltage waveform of the commercial power supply, and then remains on until the zero cross point. Therefore, by controlling the resistance value of the volume VR, the time until the terminal voltage of the capacitor C ₂ reaches the breakover voltage of the die solution Q ₂ is controlled by the firing point of the triac Q ₁ ( It is possible to adjust the period of time, and to light the lighting load at a desired dimming level. The choke coil L is covered with a coil cover to maintain insulation. In addition, a surge absorber ZNR is connected between the terminals 30 as a surge absorbing element.

By the way, the operation lever 60 is fitted to the operation shaft which protrudes forward by the volume VR. The operation lever 60 has a stopper portion 62 at the rear portion and is inserted from the rear side into a circular hole 24 formed almost in the center of the front surface of the cover 20. Here, an elastic body 66 (for example, neoprene rubber) is sandwiched between the front end face of the operating shaft of the volume VR and the operating lever 60, and between the cover 20 and the operating lever 60. It is possible to prevent the gap from occurring, and to prevent shaking of the operating lever 60 with respect to the cover 20 and to prevent water droplets and the like from entering the case 1 through the holes 24. have. Moreover, the dimming setter is comprised by the volume VR and the operation lever 60. As shown in FIG.

In addition, the dimming level can be seen as the degree of rotation of the display and the operating lever 60 provided around the operating lever 60 in front of the cover 20. By the way, in the operation lever 60, the press part 63 which presses the operation piece of the micro switch SW (refer FIG. 1) mentioned above so that an illumination load may turn off when the operation lever 60 is operated to a predetermined position is plugged. It protrudes from the element of the part 62. Therefore, when the operation lever 60 is rotated in the direction of lowering the dimming level and operated to a predetermined position, the operation piece of the micro switch SW is pressed by the pressing unit 63 so that the micro switch SW is turned off, and the illumination portion is loaded. It goes out. That is, by operating the operation lever 60, the on / off and dimming of the lighting load is achieved. In addition, in this embodiment, since the shake of the operation lever 60 with respect to the cover is prevented as described above, and the operation load of the operation lever 60 is kept substantially constant, the operation piece of the micro switch SW is pressed. (63) can be pressed more reliably.

Moreover, the V-shaped recessed part 63a is formed in the whole part of the press part 63, and the recessed part in the site | part corresponding to the said predetermined position on the back side of the cover 20 is provided. Since the engaging projection (not shown) which engages in 63a is protruded, a click feeling can be acquired when operating the operation lever 60 to the said predetermined position.

By the way, the triac Q ₁ is attached to the heat sink 40 and then soldered to the second printed board 52. The heat sink 40 is substantially U-shaped configuration with a side plate (40b) each projecting from the opposite ends of the fixing piece (40a) and a fixing piece (40a) is a TRIAC (Q ₁₎ fixed.

It is a hole formed in the second printed board 52. In this embodiment, since the heat sink 40 is formed substantially in U shape, the area of the heat sink can be enlarged compared with the case where the shape of the heat sink is almost L-shaped, and heat dissipation of the triac Q ₁ is performed efficiently. Therefore, there is an advantage that the temperature on the front side of the dimmer can be suppressed from rising and that the user is not disturbed when the dimming setting is performed. In addition, in this embodiment, since the some protrusion 10a (refer FIG. 6) is protrudingly provided in the inner side of the back of the body 10, the back of the body 10 and the fixing piece 40a of the heat sink 40 are Since there is a gap therebetween, it is possible to suppress the temperature rise on the back of the body 10.

In addition, in this embodiment, since the heat dissipation slit 17 which communicates the inside and the outside of the body 10 is formed in both sides parallel to the long longitudinal direction of the body 10, the body 10 Heat becomes hard to stay inside). Here, the slits 17 are formed on both sides of the body 10 which are substantially parallel in the long longitudinal direction, thereby making it possible to increase the number of slits 17 relatively.

Moreover, in this embodiment, since the waterproof groove 18 (refer FIG. 5) which inclines to the inclination rearward at the position above the said slit 17 is formed in the upper part of the case 1 back surface, it is in the case 1, Water droplets and the like can be prevented from entering through the slit 17.

The synthetic resin forming the attachment frame 110 is flexible and the movable both sides 115 and the connecting portion 116 can be bent. The slits 118a and 118c on both sides are formed almost in an L shape, and the slits 118b in the middle portion are formed in a straight line shape. In the frame piece 113b, each of the bridge portions 117 is provided with an elongated hole-shaped groove 119 penetrating into the front and back so that the movable both sides 115 can be bent even at a portion corresponding to the bridge portion 117. We install each.

On the other hand, on one surface of the fixed both side 114 and the movable both side 115 toward the opening window 111, a pair of locking cages 25 and the uneven crab protruded from each of the upper and lower ends of the case 1, respectively. The holding grooves 114a and 115a (refer to FIG. 11) are provided at equal pitches as well as the holding portions to be joined. Therefore, when the engagement tank 25 provided in the case 1 is concave-convex to each holding groove 114a, 115a, the attachment frame is formed in the form which exposed the front surface of the case 1 from the opening window 111. FIG. The case 1 may be attached to the 110. In addition, in order to prevent the case 1 from falling out from the attachment frame 110, the base portion of the fixed side portion 114 and the movable side portion 115 has a contact portion which abuts against the front surface of the shoulder portion 21 of the case 1 ( 114d and 115d are formed (see FIG. 11). In other words, the front face of the shoulder portion 21 abuts on the contact portions 114d and 115d, and the rear face of the locking cage 25 is locked to the holding grooves 114a and 115a, so that the case 1 is attached to the attachment frame ( 110).

Here, at each of the front end portions of the fixed side 114 and the movable window 115 toward the opening window 111, the retaining tank 25 of the case 1 is held from the rear side of the attachment frame 110. Induction sections 114b and 115b of inclined surfaces that are inclined to extend the length of each other by the tip side, in order to guide the respective locking cages 25 to the retaining grooves 114a and 115a when introduced into the grooves 114a and 115a. Is installed (see Fig. 11). To install the case 1 on the attachment frame 110, as shown in Fig. 11 (a), the retaining grooves 25a protruding from the upper surface of the case 1 are retained in the fixing grooves 114a. 11), the front end portion of the case 1 is almost coincided with the opening window 111, and the case 1 is pushed forward with respect to the attachment frame 110, as shown in FIG. A locking tank 25 protruding from the lower surface of 1) is driven into the holding groove 115a by the inclined surface 25a and the guide portion 115b while bending the movable both sides 115, and is shown in Fig. 11 (c). As described above, the locking tank 25 can be easily engaged with the holding groove 115a.

However, since the connecting portion 116 is provided on the extension line of the movable both sides 115 as described above, even if the pressing force acts on the case 1 from the front side to the rear side, the movable both sides 115 move toward the opening window 111 side. It bends so that it may fall, and the locking cage 25 of the case 1 is prevented from falling out from the holding groove 115a. Thereby, the attachment strength with respect to the attachment frame 110 of the case 1 can be improved.

On the other hand, in the base part of the fixed side part 114, the mechanism separation hole 114c which penetrates into the front and back of the attachment frame 110 between each adjacent pair of holding grooves 114a, Insert the tip of a jig mechanism, such as a driver or a disassembly jig, into the mechanism separation hole 114c with the (1) attached to the attachment frame 110, and move the case 1 from the tip of the jig. When pressed toward both sides 115, the movable both sides 115 can be bent with a slight force according to the lever principle, and engagement between the retaining grooves 114a on the fixed sides 114 side and the locking tank 25 of the case 1 The case 1 is released so that the case 1 can be removed from the attachment frame 110.

However, as described above, the attachment frame 110 has three pairs of retaining grooves 114a and 115a in the fixed side 114 and the movable side 115, respectively, and the case 1 has a pair of upper and lower sections. Since the locking cage 25 is formed, it is possible to provide up to three casings 1 to the attachment frame 110. That is, the attachment frame 110 is for three pieces, and the case 1 has set the attachment dimension so that up to three attachment frames 110 may be provided. In this way, by defining the relative attachment dimension between the case 1 and the attachment frame 110, the attachment frame 110 can be provided with any number of cases 1 in the range of one to three. Done. The pitch of each of the holding grooves 114a and 115a provided in the fixed side 114 and the movable side 115 is the same as that of the pawl 25 that protrudes into the case 1 of one unit dimension. Since the holding grooves 114a and 115a are equally spaced as described above, if the case 1 has a unit size, any two retaining grooves 114a adjacent to the fixed to-being portion 114 and the movable to-being 115 are provided. 115a) may be used to attach to attachment frame 110.

By the way, the recessed part 131 is formed in the front surface of the intermediate part of each horizontal piece 112 of the attachment frame 110, respectively. In each concave portion 131, in order to install the attachment frame 110 in a buried box (not shown), a box hole 132 through which a box screw is inserted and the attachment frame 110 are walled. Fitting metal fitting locking device for locking a screw insertion hole 133 through which a screw for directly attaching to a construction surface such as a back is inserted and a fitting metal fitting (not shown) used for installation in a wall panel or the like forming the construction surface. The hole 134 is provided.

Further, at four corners of the attachment frame 110, a makeup plate locking hole 135 for locking the locking projection 123 protruding from the rear surface of the makeup plate 120 is provided, and the makeup plate locking hole 135 is provided. By inserting and locking the locking projection 123 to the front surface of the attachment frame 110, the makeup plate 120 can be detachably installed.

The makeup plate 120 is formed by using an insulating synthetic resin, and is formed around the entire surface of the attachment frame 110 by a rectangular main part 121 and a perimeter from the periphery of the main part 121. It is formed in a substantially box shape in which the side wall 122 protruding rearwardly over is formed continuously. The locking projection 123 protrudes at four corners on the rear side of the main portion 121. Moreover, the opening part 121a which exposes the whole surface of the case 1 provided in the attachment frame 110 is provided in the center part of the main part 121. As shown in FIG. 8 illustrates a state in which the case 1 is attached to the attachment frame 110 and the makeup plate 120 is attached to the attachment frame 110.

What is necessary is just to set the dimension of the opening window 121a of the makeup plate 120 according to the number of cases provided in the attachment frame 110, for example, as shown in FIG. 12, of the outlet B of a unit dimension. The case 1 'or the case 1 " of the switch C of the unit dimension and the case 1 of the dimmer can also be addressed. In addition, 250a in Fig. 12 shows a flat plug blade into which a flat flat blade is inserted. An insertion port, 250b is a pin-type plug blade insertion port into which a pin-shaped pin-shaped plug blade is inserted, and the flat plug blade insertion port 250a and the pin-type plug blade insertion port 250b communicate with each other.

The distance between each opposing surface of the side wall 122 of the makeup plate 120 is made larger than the width dimension of the corresponding site | part of the attachment frame 110, respectively. That is, when the makeup plate 120 is attached to the front side of the attachment frame 110 arranged on the construction surface, the attachment frame 110 is settled inside the makeup plate 120, and the makeup plate 120 The leading edge of the side wall 122 abuts on the construction surface. As a result, the opposing surface of the attachment frame 110 and the makeup plate 120 does not go forward than the construction surface, and both opposing lines are almost invisible from the side, improving appearance.

In addition, on the inner side surface of the side wall 122 of the makeup plate 120, a regulating rib 124 abutting the side surface of the attachment frame 110 to prevent the positional displacement of the makeup plate 120 with respect to the attachment frame 110. Multiple rows are installed.

By the way, on the outer surfaces of both frame pieces 113a and 113b of the attachment frame 110, the inclined surface 113c which inclines so as to protrude outward from the rear side, and the elongated part which protruded outward in succession to the inclined surface 113c 113d is formed. Furthermore, ribs 125 whose rear ends abut against the front surface of the elongated portion 113d are protruded and installed on the inner surface of the upper and lower sidewalls 122 of the makeup plate 120, and the ribs 125 of the makeup plate 120 are provided. Shake is prevented. When installing the makeup plate 120 to the attachment frame 110, the regulating rib 124 of the makeup plate 120 is guided to the inclined surface 113c formed in the frame pieces 113a and 113b of the attachment frame 110. , Easy to install.

A pair of notches 126 are provided on the upper and lower sidewalls 122 of the makeup plate 120. A jig (such as a tip of a negative driver) is attached to the notch 126 to attach the makeup plate 120 to the side wall 122. When a force in a direction (forward direction) falling from the frame 110 is applied, the engagement state between the locking projection 123 of the makeup plate 120 and the makeup plate locking hole 135 of the attachment frame 110 is released. The cosmetic plate 120 may be separated from the attachment frame 110. In the frame piece 113b of the attachment frame 110, a cutout portion 136 recessed inwardly from the inclined surface 113c is provided at a position corresponding to the notch portion 126, and the notched portion 126 is fitted. The jig is released so that it can be inserted to the inside, and the force is easily acted upon when removing the makeup plate 120. In addition, ribs 137 thinner than the elongated portion 113d are successively provided from the rear end portion of the evacuation portion 136 to such an extent that they do not protrude from the notched portion 126 of the makeup plate 120. That is, there is a risk that the construction surface may be damaged by applying a force to the jig inserted into the notch portion 126 as the support point, but the rib 137 is provided to the jig inserted into the notch portion 126. When the jig abuts on the rib 137 and the makeup plate 120 is separated from the attachment frame 110, it is possible to prevent the jig from being damaged on the construction surface.

On the rear side of the makeup plate 120, when attached to the attachment frame 110, protrusion pieces 128a to 128c fitted to the three slits 118a to 118c provided on the attachment frame 110, respectively. I open it and install it. Here, the size of each protrusion piece 128a-128c is the inner peripheral surface of each slit 118a-118c, and each protrusion piece 128a-128c in the state fitted to each slit 118a-118c of the attachment frame 110 here. It is set to a dimension where only a slight gap occurs between the and. That is, in the state where the makeup plate 120 is attached to the attachment frame 110 in which the case 1 is installed, three protrusion pieces 128a to 128c are attached to each slit 118a to 118c of the attachment frame 110. Since only a slight gap is created between the inner circumferential surface of the slits 118a to 118c and each of the protrusion pieces 128a to 128c, the movement (bending) of the movable both sides 115 of the attachment frame 110 occurs. To be regulated.

By the way, although the makeup plate 120 made from synthetic resin is used in this embodiment, the metal makeup plate may be used. In the case of a metal makeup plate (not shown), it is not possible to install the locking projection 123 like the makeup plate 120 made of synthetic resin. Therefore, when attaching the metal makeup plate to the attachment frame 110, the attachment screw hole (not shown) in which the attachment screw which attaches a metal makeup plate is screwed is recessed in the attachment frame 110. What is necessary is just to install in one part 131. As a result, it is possible to cope with either the cosmetic plate 120 made of synthetic resin having the locking projection 123 and the metal cosmetic plate attached by the attachment screw.

However, the case 1 of the dimmer of the present embodiment can speak to the attachment frame 110 with a wiring mechanism such as an outlet or a switch, and can be constructed by the same construction method as the wiring mechanism. Since wiring can also be performed, the construction work by the contractor becomes easy.

In addition, a slide type may be used as the volume VR. In this case, as illustrated in FIG. 15, the slide groove 29 is formed on the front surface of the cover 20, and the volume ( The operating shaft of VR) and the operation lever 60 'may be connected. With such a configuration, compared to the case where a rotary one is used as the volume VR, the dimming level can be easily perceived.

One structure may be used. That is, the shoulders 21 'on both sides of the cover 20 are almost

The assembling frame 140 formed in the shape of a child is fitted to each other, and the substantially V-shaped locking pins 140a formed at the distal end portions of the both sides 140d of the assembling frame 140 are each of the body 10. The cover 20 and the body 10 are fixed to the end portion 19 formed on the side surface by the assembly frame 140. Moreover, each piece 140d of the assembly frame 140 is fitted to the recessed part 21c of the shoulder part 21 'and the recessed part 8 of the body 10, and each piece ( The engaging pin 140a of the tip of 140d is engaged with the end 19. Here, the case 1 is a dimension (e.g., JIS) equivalent to one of the embedded type wiring mechanisms having a unit size standardized so that up to three cases can be installed in the embedded type wiring structure attachment frame (not shown). A pair having a dimension corresponding to one of the diagonal lead wire harnesses that can be installed on the mounting frame of the diagonal lead wire harnesses, which are standardized according to the standard, and a pair capable of engaging with the holding holes provided in the mounting frames. Of the engagement tank 140b is provided at both ends of the assembly frame 140. In addition, each of the assembling frames 140 is provided with a locking hole 140c in which the locking jaws of the mounting frame are engaged when the mounting frame 140 is mounted on a metal mounting frame (not shown).

Since the case 1 formed in this way is formed with the attachment dimension similar to the unit dimension of a general wiring mechanism, up to three cases can be provided in the said attachment frame. The attachment frame has retaining holes engaged with the locking cages 140b protruding from the side edges of the assembly frame 140, respectively, on both sides surrounding the opening window, and on one side, the other side. An operating piece that can be bent is formed to change the distance between the and. When installing the case 1 to the attachment frame, if the case 1 is pressed against the attachment frame from the rear of the attachment frame, the operation piece is bent to attach the case 1 to the attachment frame, At this time, the front side of the case 1 protrudes from the opening window. On the other hand, to separate the case 1 from the attachment frame, the operation piece may be turned with a screwdriver or the like. The connection piece orthogonal to the side piece surrounding the opening window has a long hole for inserting a box screw for coupling the attachment frame to a switch box or a plate screw for installing a makeup plate (not shown) covering the front of the attachment frame. Screw holes and the like for screwing are provided. The attachment frame is a synthetic resin attachment frame. However, in the case of the metal attachment frame, the attachment frame may be coupled to the attachment frame using the locking holes 140c of the assembly frame 140. In the makeup plate, an opening window for exposing the front side of the case 1 and an insertion hole for inserting the plate screw are drilled.

Embodiment 2

The dimmer of this embodiment is demonstrated, referring FIGS. 17-23.

The case 1 of the dimmer of this embodiment is a form which exposes the whole surface of the case 1 from the opening window 111 of the said attachment frame 110 to the mounting frame 110 for an embedded type wiring apparatus, and maximum 3 It is formed in a dimension corresponding to two embedded wiring mechanisms having a unit size that can be attached to each other. The case 1 is a thermosetting synthetic resin (for example, melamine phenol resin) formed of a rectangular body having an open front surface, and an elastic synthetic resin (for example, polybutylene terephthalate resin = PBT resin) is formed by joining a cover 20 formed in a rectangular shape with an open rear surface.

The assembling tank 11 protrudes from the left and right direction (left and right direction of FIG. 18 (a)) of the body 10. On the other hand, a pair of shoulder parts 21 protrude from each of the upper and lower ends of the cover 20, and the assembly pieces 22 protrude from the upper and lower trailing edges of both sides toward the body 10, respectively. . In each assembly piece 22, an engagement hole 22a is formed in which the assembly tank 11 provided in the body 10 engages with the unevenness. At the front end of the assembly tank 11, the induction surface 11a (refer FIG. 18 (d)) inclined so that the front side may make the protrusion amount from the body 10 smaller. Therefore, when assembling and attaching the cover 20 to the body 10, the assembly piece 22 is bent along the guide surface 11a, and finally the engagement hole 22a provided in the assembly piece 22 is opened. By fitting in the assembly tank 11, the body 10 and the cover 20 are engaged. Thus, since it is necessary to bend the assembly piece 22, the cover 20 is formed from the synthetic resin which has elasticity.

In the body 10, an interior space is divided into a terminal storage chamber 13 and a circuit storage chamber 14 by partition walls 12.

In the terminal storage chamber 13 formed through the partition wall 12 in the body 10, a pair of terminals 30 serving as fastening terminals are incorporated. The terminal 30 is composed of a terminal plate 35 and a locking spring 36, and the locking spring 36 is disposed between the terminal plate 35 and the locking spring 36. And a clamping piece 36b which does not dig into the electric wire inserted into the electric wire insertion hole 15 (refer to FIG. 18 (e)), and a contact piece 36a which is in close contact with the electric wire. That is, the wire insertion opening 15 is formed in the rear wall of the body 10 so that an electric wire can be introduce | transduced between the locking spring 36 and the terminal piece 35. As shown in FIG. When the electric wire is inserted between the locking spring 36 and the terminal plate 35 through the wire insertion hole 15 from the side of the clamping piece 36B, the contact piece 36a and the clamping piece 36b are inserted. The electric wire is clamped between the terminal plate 35 by the spring force of, and the wire clamping piece 36b can not be pulled out by digging into the electric wire. In this way, the connection can be made simply by inserting the electric wire into the electric wire insertion hole 15, so that the wiring work becomes easier as compared with the case of using a screwed terminal or the like.

In the terminal storage chamber 13, a release button 37 made of a thermosetting resin (for example, made of urea resin) is arranged over both locking springs 36. The release button 37 abuts against the clamping piece 36b of both locking springs 36, and the portion where the release button 37 abuts against the clamping piece 36b is the terminal piece. It is staggered from the site | part which clamps an electric wire between 35 and a support. In this embodiment, the insulating piece 37a is integrally protruded forward from the middle of the release button 37 so that a part of the release button 37 is sandwiched between both terminals 30. Therefore, the electric wire inserted from the electric wire insertion opening 15 can be prevented from contacting the corresponding terminal 30 and the other terminal 30, and the insulation between both terminals 30 can be improved. Further, at the portion corresponding to the release button 37, an operation hole 16 (see Figs. 18E and 19) is formed in the rear wall of the body 10, and a negative driver tip or the like is formed in the operation hole 16. By pressing the release button 37, the clamping piece 36b, which penetrates the wire, is bent so as to be separated from the wire so that the wire can be pulled out. In addition, the terminal plate 35 is provided with a connecting piece 35a for mounting on the printed board 51 described later.

In the circuit storage chamber 14, a choke coil L, a heat sink 40, and the like described later mounted on the printed board 51 are incorporated. Here, the printed board 51 constitutes the printed board block 50 (refer to FIG. 20) together with the circuit component to be mounted. The printed board 51 includes the connection piece 35a of the terminal plate 35 described above. It is soldered and the printed circuit block 50 is comprised with the circuit part as shown in FIG. Between the terminals 30, a series circuit between a commercial power supply Vs and an illumination load La such as an incandescent lamp is connected by the above-described electric wire.

Between both terminals 30, a series circuit between the triac Q ₁ as the power control element and the choke coil L constituting the noise filter is inserted, and the noise filter together with the choke coil L is inserted into the series circuit. The capacitor C ₁ constituting the circuit is connected in parallel. The series circuit of the resistor R, the volume VR, and the capacitor C ₂ is connected in parallel to the triac Q ₁ , and the zener diode ZD ₁ is connected to the series circuit of the volume VR and the capacitor C ₂ . , ZD ₂ ) is connected to the series circuit. In addition, between the connection point between the volume VR and the condenser C ₂ and the triac Q ₁ , a die liquid Q ₂ as a trigger element is inserted, and the potential of the connection point is determined by the dilution Q ₂ . When the breakover voltage is reached, the triac Q ₁ is triggered on. Once turned on, the triac Q ₁ remains on until the voltage waveform of the commercial power supply Vs reaches the zero cross point. That is, it is triggered by the die solution Q ₂ every half cycle of the voltage waveform of the commercial power supply Vs, and then remains on until the zero cross point. Accordingly, the firing period of the triac Q ₁ is controlled by adjusting the time until the terminal voltage of the capacitor C ₂ reaches the breakover voltage of the triac Q ₂ by adjusting the resistance value of the volume VR. It can be adjusted, and the lighting load La can be turned on at a desired dimming level. The choke coil L is covered with a coil cover to maintain insulation. In addition, a surge absorber ZNR as a surge absorbing element is connected between the terminals 30.

By the way, the volume VR is rotational, and the operation lever 60 is fitted to the operation shaft which protruded forward. The operating lever 60 has a stopper portion 62 at the rear portion and is inserted from the rear side into a circular hole 24 formed almost in the center of the front surface of the cover 20. Herein, an elastic body 66 (for example, neoprene rubber) is fitted between the front end surface of the operating shaft of the volume VR and the operating lever 60, and between the cover 20 and the operating lever 60. Spacing can be prevented, and the operation lever 60 with respect to the cover 20 can be prevented from being shaken, and at the same time, water droplets can be prevented from entering the case 1 through the holes 24. It is. Moreover, the dimming setter is comprised by the volume VR and the operation lever 60. As shown in FIG.

In addition, the dimming level can be seen from the display provided on the periphery of the operation lever 60 on the front surface of the cover 20 and the degree of rotation of the operation lever 60. By the way, the operation lever 60 has the stopper part 62 in the back part, and the rib 62a (refer FIG. 19) protrudes from the element of the stopper part 62. As shown in FIG. On the other hand, in the rear side of the cover 20, when the operation lever 60 is rotated in the direction of lowering the dimming level to the position where the illumination load La is turned off, the engagement groove to which the rib 62a is engaged is at the tip end. The protrusion 20d (refer FIG. 19) to be formed is provided. Therefore, when the operation lever 60 is operated to the position described above, a feeling of click is obtained, the operation feeling is improved, and the user can reliably recognize that the operation is performed to the position at which the illumination load La is turned off. Unnecessary force can be prevented from being applied to the lever 60. In addition, by operating the operation lever 60, illumination load La is turned on, off and dimming is performed.

By the way, the triac Q ₁ is attached to the heat sink 40, and then soldered to the printed plate 51. The heat sink 40 is suitably bent in the form which an aluminum plate along the inner peripheral surface of the body 20, for example. The triac Q ₁ is attached to the fixed piece 40b of the heat sink 40 by the attachment screw 75 (see FIG. 17). In addition, the triac Q ₁ is previously coated with silicone grease on the surface in contact with the fixing piece 40b. In this embodiment, the area of the heat sink 40 can be enlarged by appropriately bending the heat sink 40 in the form along the inner circumferential surface of the body 20, and the heat dissipation of the triac Q ₁ is efficiently performed. Therefore, there is an advantage that the temperature on the front side of the case 1 can be suppressed from rising and that the user is not disturbed when the dimming setting is performed. In addition, in this embodiment, since the some protrusions (not shown) which contact the heat sink 40 are provided in the inner side of the back surface of the body 10, the base fragment of the back surface of the body 10 and the heat sink 40 is provided. Since a space | interval arises between 40a, the temperature rise of the back surface of the body 10 can be suppressed. In addition, a positioning hole 42 for positioning is formed in the base piece 40a of the heat dissipation plate 40 by a hole, and is inserted into the positioning hole 42 inside the rear surface of the body 20. Since the positioning ribs (not shown) which protrude are provided, positioning of the heat sink 40 is performed without using a screw etc. In addition, at both left and right ends of the base piece 40a of the heat sink 40, the engagement tanks 40h and 40g are integrally protruded, and the left and right inner surfaces of the body 20 are engaged with the engagement tanks 40h and 40g. Since the engagement protrusion 10e (refer FIG. 17) protrudes, the heat sink 40 can be easily fixed to the body 20 by press-fitting the heat sink 40 from the front of the body 20. As shown in FIG.

In addition, in the present embodiment, since a plurality of heat dissipating slits 17 communicating with the inside and the outside of the body 10 are formed on the rear surface of the body 10, heat hardly stays inside the body 10.
