Piano handle switch {PIANO HANDLE TYPE SWITCH}

The present invention relates to a piano handle type switch for inverting a contact by pressing a piano handle.

Conventionally, a piano handle type switch is provided on the front side of a switch body having a push button handle that can be pushed, and the piano handle is arranged such that one end is pivotally mounted on the switch body and the back side contacts the push button handle. It is becoming.

The piano handle is configured to press-fit the other end with one end as a support point, similar to the keyboard of the piano.

In addition, the piano handle has a larger operation surface than the push button handle, and it is also possible to perform the push operation using a part other than the finger.

By the way, as shown in FIG. 153, the switch main body 1 is equipped with the inversion handle 31 supported so that rocking with respect to the base body 5 was possible, and the contact point according to the oscillation of the inversion handle 31 is carried out. This is configured to invert.

In addition, the pressing operation of the push button handle 32 is transmitted to the reversing handle 31 through the reversing mechanism so that the reversing handle 31 alternately swings in the opposite direction for each pressing operation of the push button handle 32.

The switch mechanism part which consists of the inversion handle 31 and the contact part is accommodated in the center part of the left-right direction of the base | substrate 5, and the terminal is accommodated in the left and right both sides of the base | substrate 5 through the switch mechanism part, respectively.

The terminal is connected to the base 5 through the insertion openings 13a and 14a (see FIG. 154) of the c-shaped terminal plates 18 and 15 and the rear surface of the base 5 (bottom surface of FIG. 153). Locking springs 19 and 16 which support the electric wire inserted in between the terminal plates 18 and 15 are provided.

That is, this terminal is called a fastening terminal because the wires are prevented from being pulled out and connected by the locking springs 19 and 16 only by inserting the electric wires into the electric wire insertion ports 13a and 14a.

In addition, the base body 5 is configured by combining a body 5b having a front surface of which the switch mechanism part is stored and a cover 5a having a rear surface of the push button handle 32 protruding from the front surface thereof, Terminals composed of (18), (15) and locking springs (19), (16) are also housed in the body (5b).

By the way, in the above-described piano handle type switch, the installation is simple because the locking springs 19 and 16 enable the wires to be prevented and connected by simply inserting the electric wires into the electric wire insertion ports 13a and 14a. There is a problem that the electric wire can not flow relatively large current because only the wire is inserted between the clamping spring (19), (16) and the terminal plate (18), (15).

The present invention has been made in view of the above reasons, and an object thereof is to provide a piano handle type switch capable of increasing a current capacity than a conventional configuration.

FIG.

The base 5 of the switch body 1 is supported by a mounting frame 2 having a window hole 2a for mounting a mechanism in a rectangular frame shape.

Moreover, the plate (plate frame 120 and exterior plate 130) which has opening windows 120a and 130a which are longer and wider than the window hole 2a of the mounting frame 2 at the front side of the mounting frame 2 is wide. )) Are placed overlapping each other. The mounting frame 2 is provided with three sets of instrument mounting holes 2b in the longitudinal direction as the instrument mounting means.

Next, the switch body 1 will first be described with reference to FIGS. 1 to 9.

The base 5 of the switch body 1 is formed of a body 5b having a rectangular parallelepiped shape and at the same time a front surface of a synthetic resin molded article, and a cover 5a having a back surface coupled to the front side of the body 5b.

That is, the assembly piece 3 extends toward the back from the edge of both side walls of the short direction of the cover 5a, and the assembly hole 4 formed in the assembly piece 3 is the body 5b. The body 5b and the cover 5a are engaged by engaging with the assembling protrusions 6 formed on both side surfaces in the short direction.

The assembling protrusion 6 is formed with an inclined surface 6a which reduces the protrusion size from the body 5b closer to the cover 5a, and only applies a force to bring the cover 5a closer to the body 5b. As a result, the assembly piece 3 is simply coupled to the assembly protrusion 6.

The size of the base 5 in a short direction is formed so that up to three mounting frames can be used in the construction of a recessed wiring instrument called a diagonal lead type (see JIS C8304).

As shown in FIG. This size is called "one module dimension" in the same manner as the diagonal lead type wiring mechanism.

On the other hand, the length in the longitudinal direction of the base 5 is approximately equal to the size in the short direction of the window hole 2a, and the mounting frame 2 is provided on each side in the longitudinal direction of the cover 5a forming the front part of the base 5. A pair of mounting clicks 11a and 11b, which can be engaged with the mechanism mounting holes 2b formed in the portion surrounding the window hole 2a of the upper wall, protrude from each other, and each of the mounting clicks 11a and 11b. ) Is engaged with the mechanism mounting hole 2b so that the base 5 is supported by the mounting frame 2.

On one side wall in the longitudinal direction of the cover 5a, two incision grooves 11c in the front-rear direction with the rear end opened are formed, and a portion between the two incision grooves 11c is flexible in the thickness direction. A bent piece 11d having a property is formed.

In the cover 5a, a space 12 is formed on the rear surface side of the bent piece 11d, and the mounting click 11a is burnt from the side of the cover 5a by bending the bent piece 11d to the inside of the cover 5a. It is possible to retreat sexually.

Therefore, the mounting click 11b formed on one side of the cover 5a in the longitudinal direction is inserted into the mechanism mounting hole 2b of the mounting frame 2, and the mounting click 11a is inserted into the cover 5a. When the base 5 is inserted into the window hole 2a of the mounting frame so as to be retracted from the side, the mounting click 11a is inserted into the mechanism mounting hole 2b so that the base 5 is supported by the mounting frame 2. .

In addition, when the bending piece 11d is press-fitted into the cover 5a, the mounting click 11a can be pulled out of the mechanism mounting hole 2b to separate the base 5 from the mounting frame 2.

In order to facilitate the press-fit of the bending piece 11d, the pressing projection 11e protrudes from the rear end outer surface of the bending piece 11d. As will be described later, the mounting frame 2 is mounted on a construction surface such as a wall surface and the like, and the rear portion of the base 5 is embedded in the construction surface.

By the way, the inner space of the body 5b is divided into three chambers in the longitudinal direction, and the compartments on both sides are the terminal storage chambers 13 and 14 in which the terminals are stored, and the switch mechanism portion is stored in the center portion. The central storage chamber 23 is formed.

In the terminal storage chamber 13, a terminal made up of a terminal plate 18, a terminal screw 317, and a rectangular nut 319 screwed to the distal end of the terminal screw 317 is received. ), A terminal made of a terminal nut 15, a terminal screw 321 and a rectangular nut 316 screwed to the distal end of the terminal screw 321 are housed.

In addition, as shown in FIGS. 5 and 8, a pair of wire insertion holes 13a and 14a are formed on the rear wall of the body 5b corresponding to the terminal storage chambers 13 and 14.

In addition, grooves 313 and 314 are formed in both side surfaces of the body 5b corresponding to the terminal storage chambers 13 and 14 in the longitudinal direction, respectively, and terminals are provided in the grooves 313 and 314, respectively. Screw window holes 313a and 314a facing the heads of the screws 317 and 321 are formed.

In other words, the terminal screws 317 and 321 are accommodated in the terminal storage chambers 13 and 14 of the body 5b, respectively, in such a manner that the head faces the threaded window holes 313a and 314a. . That is, the electric wire insertion openings 13a and 14a and the screw window holes 313a and 314a are formed in the mutually adjacent surface.

In addition, the screw window holes 313a and 314a are formed in the grooves 313 and 314, so that the terminal screws 317 and 321 are formed when the terminal screws 317 and 321 are loosened. Protruding from (5) can be prevented.

On the other hand, each of the terminal plates 18 and 15 is located behind the front pieces 18a and 15a and behind the front pieces 18a and 15a so that the terminal screws 317 and 321 are inserted. Pressing pieces 18b and 15b which sandwich the electric wire inserted at the wire insertion holes 13a and 14a between the nuts 319 and 316 by turning the terminal screws 317 and 321 to be tightened. It is provided.

Here, the pressing pieces 18b and 15b are formed with U-shaped insertion grooves 18g and 15g open to face one edge and through which the terminal screws 317 and 321 are inserted.

The positional relationship between the terminal plates 18 and 15 and the wire insertion holes 13a and 14a and the length dimensions of the terminal screws 317 and 321 are loosened without tightening the terminal screws 317 and 321. An electric wire introduced into the base 5 from the electric wire insertion holes 13a and 14a is inserted between the pressing pieces 18b and 15b of the terminal plates 18 and 15 and the nuts 319 and 316. It is set to.

Therefore, in order to connect the electric wire to each of the terminal plates 18 and 15, the electric wire is inserted from the electric wire insertion openings 13a and 14a of the base 5, and it is negative through the threaded window holes 313a and 314a. The terminal screws 317, 321 are tightened with the tip of a tool such as a screwdriver to tighten the nuts 319, 316 with the pressing pieces 18b, 15b of the terminal plates 18, 15. The distance between the wires is reduced so that the wires are pinched to prevent the wires from being pulled out, and at the same time, electrical connection between the core wires of the wires and the terminal plates 18 and 15 is made.

Therefore, the wires are connected to the terminal plates 18 and 15 by tightening the terminal screws 317 and 321 as well as inserting the electric wires as in the conventional fastening terminals. The performance of the electrical connection is increased, and a large current can be made to flow compared to the fast terminal.

In the terminal of this kind of structure, it is necessary to make the insertion amount of the electric wire into the electric wire insertion openings 13a and 14a constant in order to obtain the required performance as the electric connection state and the electric connection state of the electric wire.

Thus, a gauge groove 22 is formed on the rear surface of the body 5b so that the amount of peeling off the insulation coating of the wire can be easily confirmed.

When peeling off the insulation coating, the end of the electric wire may be aligned with the gauge groove 22 to confirm the amount of the insulation coating.

Then, when the terminal screws 317, 321 are loosened through the threaded window holes 313a, 314a to the distal end of a tool such as a negative driver, the nuts 319, 316 and the terminal plates 18, 15 are removed. The distance between the pressing pieces 18b and 15b increases, and the supporting force of the electric wire becomes liquid, so that the electric wire can be taken out in this state.

The terminal support 18 housed in the terminal storage chamber 13 is integrally formed with a contact support piece 18d inserted into the central storage chamber 23, and a fixed contact 25 is provided at the distal end of the contact support piece 18d. Is formed.

In addition, a terminal piece 15 housed in the terminal storage chamber 14 is provided with a communication piece 15d extending to the central storage chamber 23, and is provided at the distal end of the communication piece 15d. The support piece 15e arrange | positioned along the inner peripheral surface of the back wall of the central storage chamber 23 is formed.

Positioning pieces 15h protrude from both edges of the intermediate portion of the communication piece 15d, and the movement of the terminal plate 15 can be restricted in the longitudinal direction of the body 5b.

The rear edge of the switch 24 made of a flat conductive plate is in contact with the support piece 15e. Protruding portions 28 are formed at both rear edges of the rear opening and closing member 24, and the protruding portions 28 have a V-shaped position controlling recess 27 having a wide front side formed in the central storage chamber 23. Is inserted into Therefore, the switch 24 can be rotated within the range of the position control recessed part 27 centering on the trailing edge in the state in which the trailing edge contacted the support piece 15e.

The switch 24 is disposed so as to face the contact support piece 18d, and forms the contact point 100 together with the fixed contact 25 at an opposing portion of the contact support piece 18d formed on the contact support piece 18d. A movable contact 29 is formed.

That is, when the switch 24 rotates, the state which isolate | separates from the state which the movable contact 29 isolate | separates from the fixed contact 25, and electrically connects the terminal board 15 and the terminal board 18 is selected.

In other words, in this embodiment, the contact point 100 of a single pole switch (so-called a break switch) used for a single pole single throw provided with a fixed contact 25 and a movable contact 29 one by one. For example, the contact point 100 can be inserted between the power supply and the load to be used as a disconnect switch for turning on and off the power supply to the load.

Each of the pair of wire insertion holes 13a and 14a described above is electrically connected to the same terminal plates 18 and 15 by wires inserted from the wire insertion holes 13a and 14a, respectively.

That is, the electric wire inserted from the two wire insertion holes 13a corresponding to the terminal plate 18 accommodated in the terminal storage chamber 13 according to the opening and closing of the contact 100 and the terminal plate stored in the terminal storage chamber 14 ( Since the conduction and non-conduction with the wire inserted from the two wire insertion holes 14a corresponding to 15 are switched simultaneously, one of the wire insertion holes 13a and 14a formed by two is transferred. I) Can be used as a wire insertion hole for wiring.

Here, in order to prevent the terminal plates 18, 15 from floating on the cover 5a side, the front peripheral surfaces 18a, 15a of the terminal plates 18, 15 are provided on the inner circumferential surface of the cover 5a. A pressing boss 53 in contact with is formed.

At the appropriate part of the back surface of the body 5b, the notation 56 which shows the structure of the contact 100, a symbol which shows a model, a rated capacity, etc. is provided.

This notation 56 incorporates a pigment containing a silicon-containing inorganic compound or silicon in the material forming the body 5b, and irradiates a laser beam so that a pattern of the notation 56 is obtained. I'm making it.

In forming such a notation 56, by using a material colored by an appropriately selected pigment, it is possible to give a clear contrast while using a relatively low intensity laser beam.

However, the contact point 100 is provided with the reverse spring 30, the reverse handle 31, the push button handle 32, the slide cam 33, and the return spring 37 installed to rotate the switch 24. It constitutes a switch mechanism part.

The reversal spring 31 is a coil spring, and a spring sheet piece 24a protruding in front of the switch 24 is inserted into the rear end of the reversal spring 30, and the front end is inverted handle. The rear surface provided in 31 is accommodated in the opened cylinder part 31a.

The reversal handle 31 exposes the front end portion to the front surface side of the cover 5a through the through hole 52 formed in the bottom wall of the groove 51 formed in the front surface of the cover 5a.

Further, on both sides of the intermediate portion of the reversal handle 31, a triangular support point projection 31d is formed in which the front end is narrowed, and is formed at both edges of the through hole 52, and the bearing portion 50 is opened to the rear. Since the support point projection 31b is pivotally supported, the reversal handle 31 is pivotably mounted with respect to the cover 5a.

That is, by inserting the front end of the reversal handle 31 into the through hole 52 of the cover 5a from the rear side, and inserting the support point projection 31b into the bearing part 50, the reversal handle with respect to the cover 5a ( 31) can be shaken.

As described above, the reversal handle 31 is connected to the switch 24 via the reversal spring 30, and when the reversal handle 31 swings, the reversal spring 30 is most compressed in the middle of the swing range. Pass the location.

Before and after this position, the direction of the spring force acting on the switch 24 in the reverse spring 30 is reversed, and the switch 24 moves rapidly by the spring force of the reverse spring 30.

However, the pair of engaging projections 34 projecting forward and engaging the slide cam 33 on both side portions of the inverted handle 31 exposed to the front side of the cover 5a through the through hole 52. ) Is installed.

The slide cam 33 is a push button in the plane including the swing direction of the reversal handle 31 in accordance with the positional relationship of the reversal handle 31 during the push operation of the push button handle 32 provided on the cover 5a. It is comprised so that it may slide along the back surface of the handle 32.

The structure of the slide cam 33 is mentioned later.

The push button handle 32 has guide protrusions 36 protruding at the rear ends of both outer sides in the longitudinal direction, and the front and rear directions (up and down in FIG. 8) at the rear of both inner circumferential surfaces of the grooves 51 of the cover 5a. The guide projection 36 is inserted into the guide groove 35 formed along the direction), and thus the guide projection 36 is movable in the front-rear direction and prevented from falling out.

A projection 32d is formed on the rear surface of the pushbutton handle 32, and the projection spring 32 is inserted into the hole drilled in the flat 37b of the return spring 37 made of a leaf spring, whereby the return spring ( 37) is mounted to the back of the push button handle (32).

The return spring 37 is formed by integrally extending the two return spring pieces 37a that are openly enlarged toward the rear side from the flat piece 37b, and the tip end of the spring piece 37a of the return spring 37 is formed in the groove 51. The push button handle 32 is urged toward the front side by elastically connecting to the bottom surface of the back panel).

The slide cam 33 is molded in a U-shape by a thermoplastic resin rich in elasticity such as polyacetal, and corresponds to the engaging projection 34 of the reversal handle 31 on the rear side of the opposite side portion. The engaging cam body 38 is formed to protrude, and has a shape integrally formed so that a pair of spring pieces 33a (refer to FIG. 11) is made into an arm shape in the center of the other side edge part. As shown in FIG. 11, the projections 32a protruding from the back of the push button handle 32 are inserted between the spring pieces 33a, so that the slide cam 33 swings on the back of the push button handle 32. This mounting is possible, and the return force is applied to the slide cam 33 by the elasticity of the spring piece 33a.

A pair of shaft portions 192 projecting obliquely forward are integrally formed at the surface end of the cover 5a of the base 5 of the switch body 1 so as to pivotally mount the piano handle 43. .

The front end of the shaft portion 192 is formed in a columnar shape along the short direction of the cover 5a. At one end of the rear surface of the piano handle 43, as shown in Fig. 10, a bearing portion 191 is formed in which a metal bearing spring 191b formed by a leaf spring is mounted in the insertion hole 191a.

The insertion hole 191a has a locking hole 190 on one side of the inner circumferential surface, and engages the release preventing click 191c of the bearing spring 191b accommodated in the insertion hole 191a to fit the bearing spring 191b. ) Is fixed.

The bearing spring 191b is curved to protrude the tip into the insertion hole 191a to support the shaft portion 192 at the protrusion 191d and the insertion hole 191a.

Since the protruding portion 191d of the bearing spring 191b is formed near the opening of the insertion hole 191a, the shaft portion 192 formed in the switch body 1 is narrower than the inside of the insertion hole 191a. ) Is elastically inserted into the insertion hole 191a against the spring force of the bearing spring 191b, so that the shaft portion 192 and the bearing portion 191 are pivotally mounted so that they do not easily fall out.

In this manner, the pivot handle 43 can be pivotally mounted by inserting the shaft portion 192 into the bearing portion 191 so as to be rotatable. Then, the other end of the piano handle 43 is formed to protrude from the separation prevention piece (43a) for preventing the falling out toward the rear.

The separation preventing piece 43a is inserted into the vacant space 12 through the insertion hole 54 formed in the front wall of the cover 5a, and the locking click 43b formed at the distal end of the separation preventing piece 43a is inserted. By engaging the edges around the holes 54, the rotation range of the piano handle 43 is restricted. As shown in FIG. 3, three insertion holes 54 are formed side by side.

As described above, when the piano handle 43 is mounted on the switch body 1 and the other end of the piano handle 43 is pressed, the bearing portion 191, the shaft portion 192, and the pivot mounting portion are centered. The piano handle 43 rotates.

A pair of switch operating ribs 43c protrudes from the rear of the piano handle 43. When the piano handle 43 is pressed, the switch operating ribs 43c are pressed to the switch body 1 by the switch operating ribs 43c. The button handle 32 is pressed into the base 5.

Next, the operation of the switch body 1 will be described briefly.

Fig. 11 shows a state in which the movable contact 29 is in contact with the fixed contact 25, that is, the contact 100 is closed, and the reversal handle 31 is biased to the right side of the drawing. 33 is located at the center position of the movement range by the spring piece 33a.

When pressing force is applied to the piano handle 43 (not shown in FIG. 11) in this state, the push button handle 32 is pressed into the body 5 against the return spring 37, and the push button is pressed. The slide cam 33 along with the handle 32 moves downward in FIG. 11B.

At this time, the engagement cam body 38 on the left side of the slide cam 33 contacts the engagement protrusion 34 on the left side of the inversion handle 31 and presses the left end of the inversion handle 31, thereby inverting the handle 31. It rotates to the left centering around the front end of this support point projection 31b.

The engagement cam body 38 on the left side of the slide cam 33 is located on the left side than the engagement protrusion 34 on the left side of the inversion handle 31, and the slide cam 33 moves to the left side as the inversion handle 31 rotates. As shown in Fig. 12, the slide cam 33 slides to the left in the drawing.

In this manner, as shown in FIG. 13, the inversion handle 31 is biased to the left side of the drawing, the inversion spring 30 is inverted so that the switch 24 is inverted and the movable contact 29 is separated from the fixed contact 25. That is, the contact point 100 inverts to the open state.

Thereafter, when the pressing force applied to the piano handle 43 is released, the push button handle 32 is returned by the spring force of the return spring 37 to contact the push button handle 32 as shown in FIG. The piano handle 43 also returns to its original position.

At the same time, the slide cam 33 also slides with the spring force of the spring piece 33a and returns to the center position.

Therefore, if the pressing force is applied to the piano handle 43 again when the contact point 100 is in the open position, the reversal handle 31 can be rotated in the same manner as described above.

However, when the contact point 100 is in the open state, the engagement protrusion 34 on the right side of the inversion handle 31 contacts the engagement cam body 38 on the right side of the slide cam 33, so that the inversion handle 31 moves to the right side. By rotating, the movable contact 29 is brought into contact with the fixed contact 25 through the reverse spring 30.

Thus, when the pressure is released from the piano handle 43 after the contact 100 is inverted, the state returns to the state shown in FIG.

In other words, in this embodiment, the contact point 100 is opened and closed for each pressing operation of the piano handle 43.

That is, the converter mechanism for converting the pressing operation of the push button handle 32 into the swinging of the reversing handle 31 by the engaging projection 34 and the return spring 37 of the slide cam 33 and the reversing handle 31. It is composed.

By the way, since the above-described mounting frame 2 can mount three switch bodies 1 of one module size, the mounting frame 2 will be referred to as three mounting frames 2.

That is, two sets of mechanism mounting holes 2b, 2b on which the mounting clicks 11a, 11b of the switch body 1 are held on one side of the window hole 2a of the mounting frame 2 are held. It is formed by three sets, and it is possible to select three mounting positions of the switch main body 1 in the window hole 2a.

Here, the three mounting positions in the case where the switch body 1 is mounted on the mounting frame 2 by matching the short direction of the switch body 1 in the longitudinal direction of the window hole 2a are respectively an upper position, a center position, and a lower end. Let's call it location.

In addition, as the piano handle 43 used for mounting one switch body 1 of one module size to the mounting frame 2, as shown in FIG. 15, a plate (plate frame 120 and an external plate ( 130), the piano handle 43 having a size enough to cover the openings 120a and 130a of one) will be referred to as one piano handle 43.

Similarly, as a piano handle 43 used when two switch bodies 1 of one module size are mounted on three mounting frames 2, each of them is mounted on each switch body 1 as shown in FIG. Therefore, the piano handle 43 having a size enough to cover two opening windows 120a and 130a of the plate will be referred to as two piano handles 43.

Moreover, as the piano handle 43 used when two switch bodies 1 of one module size are mounted on the three mounting frames 2, they are respectively attached to each switch body 1 as shown in FIG. Therefore, the piano handle 43 having a size enough to cover three opening windows 120a and 130a of the plate will be referred to as three piano handles 43.

The relationship between the size of the above-described three types of piano handles 43 (short direction of the switch body 1) is (up and down size of one piano handle 43) ≒ (of two piano handles 43). Up and down size) x 2 ≒ (up and down size of the three piano handles 43) x 3.

As described above, the opening windows 120a and 130a of the plate are longer and wider than the window holes 2a of the mounting frame 2, and the switch body 1 is inserted into the window holes 2a. Since it is attached, the upper and lower sizes of the three piano handles 43 are larger than the upper and lower sizes of the switch body 1.

That is, any piano handle 43 has a larger area of operation surface than the push button handle 32, so that it is easier to push the piano handle 43 than to push the push button handle 32.

15 to 21 show a case in which only one switch body 1 is mounted in the window hole 2a of the mounting frame 2, and one piano handle 43 is shown in FIGS.

As described above, the bearing portion 191 (see FIG. 10) provided at one end of the rear surface of the piano handle 43 has a center portion in the vertical direction so as to correspond to the pair of shaft portions 192 provided in the switch body 1. Two are installed nearby.

However, the bearing springs 191b mounted to the respective bearing portions 191 of the piano handle 43 are formed of one continuous member.

The piano handle 43 fits the two shaft portions 192 of the switch body 1 into the two bearing portions 191 of the piano handle 43 so that the center of the switch body 1 and the vertical direction of the switch body 1 are one. It is mounted so as to coincide with the center of the up and down direction of the piano handle 43.

In addition, at the other end of the rear surface of one piano handle 43, two release preventing pieces 43a protrude and are formed near the center in the vertical direction, and each release preventing piece 43a is inserted at the top and bottom of the switch body 1. It is inserted into the hole 54.

By the way, as shown in FIG. 24 and FIG. 25, as a center part of the up-down direction of the piano handle 43, the window hole 252 is formed in the front and back of the piano handle 43 on the other end side, and is provided in this window hole 252. A name cover 253 made of a transparent material such as acrylic resin is inserted at the back side of the piano handle 43.

As shown in Figs. 25 to 27, the name cover 253 has a rectangular flat plate shape and includes a main part 253a having a receiving groove 253b on which the name card 250 is accommodated on the back side thereof, and a main part 253a. The insertion part 253c which is formed in the front side of the main part 253a in the size smaller than the main part 253a, and is inserted in the window hole 252, and the thin plate which protruded to the side from both sides along the longitudinal direction of the main part 253a. ), The fixed portion 253d and the pivot support portion 253e protruding laterally from one end side in the longitudinal direction of the main portion 253a are integrally formed with the fixed portion 253d.

The door 254 is pivotally supported by the pivot support part 253e of the name cover 253 so that it can be opened and closed. As shown in FIGS. 25-27, this door 254 is a pair of receiving pieces 254b which protruded from the rectangular flat plate-shaped main piece and the both ends of one end side of the main piece 254a. ) And an operation piece (divided by a pair of cutouts 254d on the other end side of the shaft body 254c and the other end side of the main piece 254a) protruding from the tip end side of each receiving piece 254b. 254e and a pair of arm pieces 254f, and projections 254g protruding laterally on the tip end side of each arm piece 254f.

And the shaft body 254c of each receiving piece 254b is rotatably inserted in the bearing part 253f which opened to the inner surface of the pivot support part 253e of the name cover 253, and is centered around the shaft body 254c. The storage groove 253b of the cover 253 can be opened and closed.

Then, the projections formed on both arm pieces 254f of the door 254 are engaged with the engaging portions 253g formed on both sides of the inner surface both ends along the longitudinal direction on the rear surface side of the main portion 253a of the name cover 253. Press-fit engagement is intended to maintain the closed state.

On the other hand, an insertion recess 255 for inserting the name cover 253 in which the door 254 is rotatably mounted, as shown in FIG. 28, is provided at the peripheral edge of the window hole 252 on the back of the piano handle 43. Formed.

A protrusion 256 along the longitudinal direction of the window hole 252 is formed to protrude from a portion of the insertion recess 255 that faces the fixing portion 253d of the name cover 253.

In addition, an engaging groove 257 is formed in the end side surface at which the separation preventing piece 43a of the insertion recess 255 is formed, and as shown in FIG. The tip of the rib 253h protruding from the end of the main portion 253a is locked.

That is, when the rib 253h is locked to the locking groove 257 and the name cover 253 is inserted into the insertion recess 255, the name cover 253 can be temporarily fixed, and the protrusion 256 is fixed in this temporary fixing state. Is melted with ultrasonic waves, and the fixing portion 253d of the name cover 253 is ultrasonically welded to the piano handle 43.

Thus, when storing the name card 250, the operation piece 254e is erected so that the door 254 is opened from the back side of the name cover 253, and the name card 250 is stored in the name cover 253. When the door 254 is closed in this state and the door 254 is closed in this state, the name card 250 is sandwiched between the door 254 and the name cover 253 to be inserted into the window hole 252 of the piano handle 43. Through the insertion part 253c and the main part 253a, the notation (for example, letters, numbers, symbols, etc.) of the name card 250 can be confirmed on the surface side.

Here, in this embodiment, a pair of attachment prevention ribs 253j protrude from the bottom end side end of the storage groove 253b of the main portion 253a, and as shown in Figs. 27 and 30, the storage groove ( The name card 250 stored in the 253b is lifted from the bottom of the storage groove 253b by the attachment preventing rib 253j.

That is, when the contact area between the name card 250 and the bottom of the receiving groove 253b is large, the name card 250 is attached to the bottom of the receiving groove 253b of the name cover 230 by static electricity, thereby causing the name card 250 to be attached. Since it is difficult to separate the separation, the contact prevention rib 253j reduces the contact area between the name card 250 and the bottom of the receiving groove 253b, thereby facilitating the separation of the name card 250.

A pair of the switch operating ribs 43c for pressing and pushing the pushbutton handle 32 of the switch body 1 is formed on both sides of the insertion recess 255 facing the window hole 252 therebetween. Since the insertion hole 253i through which the switch operating rib 43c is inserted is formed in the main portion 253a of the name cover 253, even when the name cover 253 is attached, the switch operating rib 43c is used. Push operation of the push button handle 32 is not disturbed.

In the present embodiment, as described above, the name cover 253 in which the door 254 is rotatably mounted and the unitized name cover 253 is fixed to the back side of the piano handle 43, therefore, the name cover 253 is mounted on the piano handle 43. Compared to the structure in which the door 254 is mounted on the back of the piano handle 43, the assembly process of assembling the name cover 253 and the door 254 on the piano handle 43 is greatly simplified. can do.

On the other end of the surface of the piano handle 43, a push position indicating protrusion 114 protrudes from the center position in the up and down direction, and an end of the push position indicating protrusion which should apply pressure to the piano handle 43. It shows that it is the (114) side.

In addition, a plurality of exterior lines 115 are formed in a stripe shape on the upper and lower sides of the name cover 253 on the surface of the piano handle 43.

The exterior line 115 applies a laser beam to a synthetic resin molded article forming the piano handle 43 such that irregularities are not substantially formed on the surface of the piano handle 43 (they cannot be touched by hand). It forms by irradiating and carbonizing and developing a color so that a color difference may not arise with another part.

In other words, the exterior line 115 and the name cover 253 are formed independently. Therefore, in the varieties which do not particularly need the name card 250 and the name cover 253, the name card 250, the name cover 253, and the door 254 are provided as shown in Figs. One piano handle 43 may be employed.

However, in the case where the two switch bodies 1 are mounted in the window hole 252 of the mounting frame 2, as shown in FIGS. 33 to 39, the switch bodies 1 may be mounted at the upper and lower positions, respectively. It becomes possible.

Each switch body 1 is equipped with two piano handles 43 shown in Figs. 40 to 43, respectively.

Like the three piano handles 43, the two piano handles 43 have two bearing portions 191 at the center in the vertical direction, and each switch mounted at the upper position and the lower position with respect to the mounting frame 2; The up-down center position of the main body 1 and the up-down center position of each piano handle 43 are mounted so that it may correspond.

As a result, in the two piano handles 43, the same one can be used in common without distinguishing the upper position and the lower position.

Here, the terminal plate 20 is formed with a U-shaped insertion groove 20g, which is opened to face one edge and into which the terminal screw 317 is inserted.

The pair of wire insertion ports 13a and 13a is formed at a portion of the rear wall of the body 5b corresponding to the terminal plates 18 and 20 accommodated in the terminal storage chamber 13, and the first embodiment. The distance between the wire insertion ports 13a and 13a is larger than the shape.

The positional relationship between the terminal plates 18 and 20 and the wire insertion ports 13a and 13a and the length sizes of the terminal screws 317 and 317 are loosened without tightening the terminal screws 317 and 317. An electric wire introduced into the base 5 from the electric wire insertion holes 13a and 13a is inserted between the pressing pieces 18b and 20b of the terminal plates 18 and 20 and the nuts 319 and 319. It is set to.

Therefore, in order to connect the electric wire to each of the terminal plates 18 and 20, the electric wire is inserted from the electric wire insertion openings 13a and 13a of the base 5, and it is negative through the screw window holes 313a and 313a. (Date) Pushing pieces 18b and 20b of nuts 319 and 319 and terminal plates 18 and 20 by turning the terminal screws 317 and 321 to the end of a tool such as a screwdriver. ), The distance between the wires becomes small and the wires are clamped to prevent them from falling out.

The terminal plate 20 is provided with an L-shaped contact support piece 20d extending to a portion facing the contact support piece 18d provided on the terminal plate 18, and is provided on the terminal plate 18 at the contact support piece 20d. A stationary contact 25b is provided opposite the stationary contact 25a.

That is, when the switch 24 swings according to the swing of the reversal handle 31, the movable contact 29 selectively contacts one of both fixed contacts 25a and 25b.

Therefore, the electric wire connected to the terminal plate 15 is selectively electrically connected to one of the electric wire connected to the terminal plate 18 and the electric wire connected to the terminal plate 20.

In addition, since the other structure is the same as that of 1st Embodiment, the same code | symbol is attached | subjected to the same component, and description is abbreviate | omitted.

In addition, the piano handle 43 can use the same thing as 1st Embodiment.

Next, the operation of the switch body 1 will be described briefly.

FIG. 82 shows a state in which the movable contact 29 is in contact with the fixed contact 25a, and the inversion handle 31 is biased to the right side of the drawing. At that time, the slide cam 33 is located at the center position of the movement range by the spring piece 33a.

When pressing force is applied to the piano handle 43 (not shown in FIG. 82) in this state, the push button handle 32 is pressed into the body 5 against the return spring 37, and the push button is pressed. The slide cam 33 along with the handle 32 moves downward in FIG. 82B.

At this time, the engagement cam body 38 on the left side of the slide cam 33 contacts the engagement protrusion 34 on the left side of the inversion handle 31 and presses the left end of the inversion handle 31, thereby inverting the handle 31. It rotates to the left centering around the front end of this support point projection 31b.

The engagement cam body 38 on the left side of the slide cam 33 is located on the left side than the engagement protrusion 34 on the left side of the inversion handle 31, and the slide cam 33 moves to the left side as the inversion handle 31 rotates. As shown in Fig. 83, the slide cam 33 slides to the left in the drawing.

Thus, as shown in FIG. 84, the inversion handle 31 is biased to the left side of the drawing, the inversion spring 30 is inverted so that the switch 24 is inverted, and the movable contact 29 is separated from the fixed contact 25 so that the fixed contact ( Invert to 25a).

Thereafter, when the pressing force applied to the piano handle 43 is released, the push button handle 32 is returned by the spring force of the return spring 37 to contact the push button handle 32 as shown in FIG. The piano handle 43 also returns to its original position.

At the same time, the slide cam 33 also slides with the spring force of the spring piece 33a and returns to the center position.

Therefore, if the pressing force is applied to the piano handle 43 again when the movable contact 29 is in contact with the fixed contact 25a, the inversion handle 31 can be rotated in the same manner as in the above-described operation. .

However, in the state where the movable contact 29 is in contact with the fixed contact 25a, the engagement projection 34 on the right side of the inversion handle 31 contacts the engagement cam body 38 on the right side of the slide cam 33. The reversal handle 31 is rotated to the right, so that the movable contact 29 is separated from the fixed contact 25 through the reversal spring 30.

Thus, if the pressing force is released from the piano handle 43 after the contact 100 is inverted, the state returns to the state shown in FIG.

(5th Embodiment)

The basic structure of this embodiment is substantially the same as that of the first embodiment, and as shown in Figs. 104 to 112, the position indicator L1 made of neon lamp and the current-limiting resistor R1 are provided. Display block B1 is added.

Here, the position indicator L1 lights up in the open state of the contact 100 as described later.

In the display block B1 of the present embodiment, a position indicator light L1 made of a resistor R1 made of a chip resistor and a neon lamp connected in series with the resistor R1 is connected to a printed circuit board 66 formed in an L shape. It is mounted.

In addition. The printed circuit board 66 includes contacts 61a formed of a conductive metal base plate to enable elastic connection to the front sides 15a, 18a of the terminal plates 15, 18, 62a is also connected.

The position indicator light L1 of the display block B1 is accommodated in the cover 5a at a portion corresponding to the terminal storage chamber 13, and the contacts 61a, 62a are mounted on the terminal plates 15, 18. It is arrange | positioned so that it may respectively contact the front parts 15a and 18a.

That is, an accommodating groove 55 is formed at one end of the cover 5a in the longitudinal direction, and the position indicator L1 is accommodated in the accommodating groove 55.

The above-described contacts 61a, 62a are mounted on the printed board 66 so that the series circuit between the resistor R1 and the position indicator L1 is inserted between the both terminal boards 15,18.

Therefore, the internal circuit of the switch body 1 is shown in FIG.

In this embodiment, the contact point 100 of the single pole switch (so-called disconnection switch) used for the single pole single throw provided with the fixed contact 25 and the movable contact 29 one by one is comprised, and the resistor R1 And a series circuit of the position indicator L1 are connected in parallel to the contact point 100.

In this configuration, if the contact point 100 is inserted between the electrode and the load to be used as a disconnect switch for turning on and off the power supply to the load, the position indicator L1 turns on when the power is not supplied to the load. do.

That is, if the lighting load is used as the load, the position indicator L1 lights up when the lighting load is turned off, so that the position of the switch can be easily checked even in a dark place.

On the front wall of the portion corresponding to the accommodating groove 55 in the cover 5a, a through hole window 40 communicating with the accommodating groove 55 is formed at a portion between the shaft portions 192, and the perforated hole window 40 is formed. A lamp cover 41 having a light transmitting property is mounted on the lamp cover 41.

Therefore, the blinking / off state of the position indicator L1 can be seen through the lamp cover 41.

However, as shown in FIGS. 114-119, the piano handle 43 is attached to the switch main body 1 in the up-down direction center part in the one end part in which the bearing part 191 is provided in the piano handle 43. As shown to FIG. As described in the first embodiment, the display window 112 is formed at a portion corresponding to the lamp cover 41 of the switch body 1, and the front end portion of the display portion 113 is formed on the display window 112. It is fitted from the back side of the handle 43.

The display portion 113 is made of a light-transmitting synthetic resin, and has a rectangular flat plate-shaped main body 113a whose tip portion is fitted to the display window 112 and side pieces protruding laterally from both side surfaces of the end portion of the main body 113a. 113b is integrally formed.

Meanwhile, as shown in Figs. 116 and 117, the tip portion is formed in three parts around the display window 112 on the back of the piano handle 43 so as to have a long hole shape formed on the side piece 113b of the display portion 113. A press-fit rib 112a press-fitted into the fixing hole 113c is formed to protrude.

That is, the front end portion of the main body 113a is fitted into the display window 112 from the rear surface side of the piano handle 43, and the press-fit rib 112a is press-fitted into the fixing hole 113c of the side piece 113b, thereby FIG. As shown in FIG. 119, the display part 113 is fixed to the piano handle 43. As shown in FIG.

Then, when the piano handle 43 is attached to the switch body 1, the rear end surface of the main body 113a of the display unit 113 is disposed opposite the lamp cover 41 of the switch body 1, and the lamp cover 41 The light of the position indicator L1 emitted from) is incident on the rear end surface of the main body 113a and irradiated to the outside from the front end surface of the main body 113a inserted into the display window 112.

The back end surface of the main body 113a of the display unit 113 is subjected to time signal processing, and the incident light is diffused to widen the viewing angle in the upward direction.

Thus, in the related art, a lens mounted on the rear surface side of the piano handle 43 and a display portion mounted on the surface side of the display window 112 formed on the piano handle 43 are constituted as separate components. As described above, since the display portion 113 is formed by integrating the conventional lens, the number of parts can be reduced and the assembly work can be simplified.

Moreover, in the varieties which do not particularly need the name card 250 and the name cover 253 in the present embodiment, as shown in Figs. 120 and 121, the name card 250, the name cover 253 and the door 254 are shown. You may employ | adopt the three piano handles 43 which are not provided.

As for the two piano handles 43 used when the two switch bodies 1 are mounted on the mounting frame, as shown in FIGS. 122 to 123, the same display window as the one piano handle 43 ( 112 and a display portion 113 are provided.

Moreover, in the varieties which do not particularly need the name card 250 and the name cover 253, the name card 250, the name cover 253, and the door 254 are provided as shown in Figs. Two piano handles 43 may be employed.

By the way, as can be seen from the description of the first embodiment, in the case where the three switch bodies 1 are mounted to the mounting frame, the center of the up and down direction of the switch body 1 is the piano in the upper position and the lower position. It does not coincide with the center of the up-down direction of the handle 43.

Thus, in the three piano handles 43, as shown in Figs. 126 to 130, the display portion 140 and the rear surface of the display portion 140 having a smaller thickness than the one or two piano handles 43 are optically shown. The prism 200 to be coupled is installed.

As shown in FIGS. 127 and 130, the prism 200 is formed in a shape that is diffused upward and downward from the display window 112 at the rear side of the piano handle 43, and the emission surface 201 has a triangular waveform. Concave-convex shape.

Lateral protruding prism portions 207 are provided from the rear side of the uneven surface of the exit surface 201 toward the upper and lower sides, and the side protruding prism portions 207 are located at the upper positions of the mounting frames 2 on the rear portion. An incidence surface 203 is formed for incidence of light from the mounted switch body 1 or the switch body 1 mounted at a lower position, and the light entering the interior from the incidence surface 203 is projected into the side protruding prism portion 207. Is reflected by the first reflecting surface 204 and the second reflecting surface 205 and is emitted from the emitting surface 201.

In addition, an incidence surface 202 is formed on the rear side of the uneven surface 201 of the uneven surface, which is formed of a recess in which light from the switch body 1 mounted at the center position of the mounting frame 2 is incident. The inner walls of both sides of the recessed part of the entrance face 202 are inclined so that one end is very asymmetric to the rear of the exit face 201, and the second half of the light guided in the prism 200 is inclined. The slope 205 is formed.

The prism 200 having the above-described configuration is mounted on the rear side of the three piano handles 43 by ultrasonic welding so that the emission surface 201 faces the display section 140 provided on the three piano handles 43.

Here, the display section 140 of the present embodiment is formed of a light-transmissive resin, and is deposited on the rear surface side of the piano handle 43 on the display window 112 of the piano handle 43. A coupling portion 140a coupled to the display window 112 of the 43 and a side portion 140b protruding from both ends of the back side of the coupling portion 140a and having a downward inclined surface, as shown in FIG. 130. Likewise, the tip portion of the side portion 140b is engaged with the edge around the rear surface side of the window hole 252 and clamped by the piano handle 43 and the prism 200.

That is, since both the display unit 140 and the prism 200 can be mounted on the rear side of the piano handle 43, the assembling work can be simplified.

The downwardly inclined surface formed on the side portion 140b of the display portion 140 increases the viewing angle in the upward direction along with the asymmetrical second reflective surface 203 of the prism 200 to facilitate viewing.

Thus, in the three piano handles 43 mounted on the switch body 1 at the center position of the mounting frame 2, the incident surface 202 faces the floodlight window 40 of the switch body 1 In addition, in the three piano handles 43 mounted on the switch body 1 in the upper position, the incident surface 203 of the lower side protruding prism portion 207 is the floodlight window 40 of the switch body 1. In the three piano handles 43 opposed to and mounted on the switch body 1 in the lower position, the incident surface 203 of the upper side protruding prism portion 207 is the light-transmitting window of the switch body 1. It is against 40.

Then, the light of the position indicator light L1 emitted from the light transmission window 40 of the switch body 1 at the upper position or the lower position enters the side protruding prism portion 207 from the incident surface 203 and protrudes laterally. The light is reflected within the prism portion 207 and exits from the uneven surface 201 toward the display portion 140.

The light emitted from the light transmission window 40 of the switch body 1 at the center position is incident from the incident surface 202 and exits from the uneven surface 201 toward the display unit 140.

In this case, by making the exit surface 201 into a concave-convex shape of a triangular waveform, the emission of light emitted from the exit surface 201 can be made almost in the same direction by eliminating bias.

Then, the light emitted from the light transmission window 40 of the switch body 1 at the lower position is the asymmetric second reflecting surface 203 of the corresponding prism 200 and the side portion 140b which is the incident surface of the display portion 140.
