Abstract

PROBLEM TO BE SOLVED: To enhance the reliability of delay action and reduce noises. SOLUTION: When a setting operation is made by an operating part or a handle 90, a suction cup 23b is moved following the movement of a card 26, and sucked and held by a sucked body 24. The air from an air inlet 26e of the card 26 enters a space formed between the suction cup 23b and the sucked body 24 through an air-permeable member 32a within an air-permeable- member press-in part 23d. When the handle 90 is operated to remove the setting, the card 26 is moved forward as the suction force of the suction cup 23b on the sucked body 24 becomes weaker than the spring force of a return spring 27, a contact spring 70 is pushed up by a contact-spring pushing part 26c, and a movable contact parts from a fixed contact 64b. A terminal made up of a terminal board 63c connected to the movable contact and a lock spring, is provided.

[0002]

2. Description of the Related Art A delay switch of this type is known, for example, for operating a ventilation fan and a lighting load of a toilet (see Japanese Patent Application Laid-Open No. 61-55825). This conventional delay switch has a control function of turning on a ventilation fan and a lighting load by operating a handle as an operation unit, turning off a lighting load by releasing a setting of a steering wheel, and turning off the ventilation fan after a predetermined time (delay time). With In this conventional delay switch, the delay unit that determines the delay time has a gear, and the gear of the delay unit is interlocked with the operation of the steering wheel.

[0003]

In the above-mentioned conventional structure, the structure of the delay unit for determining the delay time is complicated and the production cost is high. The operation feeling is poor because the gear of the delay unit is interlocked with the operation of the steering wheel.

The air permeable member is formed in a columnar shape, and the air introduction portion of the suction block has at least two types of air permeable members having different outer diameters, into which a first press-fit portion and a first press-fit portion having a larger inner diameter can be press-fitted. A second press-fitting portion having a smaller inner diameter than the second press-fitting portion is formed along the direction of the press-fitting. A delay time is required until the suction cup block separates from the object to be sucked due to the balance with the spring force of the spring, eliminating the need for conventional gears, making the configuration simpler and more reliable than conventional delay switches with delay units. Cost, cost can be reduced, and noise is reduced. In addition, since a gear is not required unlike the related art, the operation of the operation unit becomes smooth. Further, in a state in which the suction cup block is adsorbed to the suction object, the air suction section has an air permeable member that is press-fitted into an air introduction section that communicates with an internal space formed between the suction block and the suction object. At least two types of air permeable members having different outer diameters can be press-fitted, and a first press-fit portion having a larger inner diameter and a second press-fit portion having a smaller inner diameter than the first press-fit portion are formed along the press-fit direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (Embodiment 1) First, the operation of a delay switch according to the present embodiment will be briefly described, and then each component will be described in detail.

FIG. 3 shows the OFF state of the delay switch of the present embodiment. In this state, when the handle 90 serving as the operating portion is turned on (set operation), the arm pressing piece 90b of the handle 90 is rotated, and the arm pressing piece is turned. The distal end of 90 b moves along the curved portion 50 a of the arm 50. When the handle 90 is turned on, the coil spring 96 is tilted as shown in FIG. 1 so that the movable contact 74 provided on the rocking body 73 comes into contact with the fixed contact 64b of the terminal plate 63b, and this electric circuit is turned on. At the same time, when the arm pressing piece 90b rotates, the arm 50 rotates, and the card pressing portion 52 at the tip of the arm 50 presses the pressed portion 26a of the card 26, and the return spring 27 made of a coil spring is attached. The card 26 moves against the force (pressed down in FIG. 3), and the movable contact 72 of the contact spring 70 is moved.
Contacts the fixed contact 64a of the terminal plate 63a, and this electric path is turned on. Further, when the card 26 moves, the suction cup 23b of the suction cup block 23 is pushed down to a position where the suction cup 23 comes into contact with the suction target 24, and the suction cup 23b is adsorbed on the suction target 24, and in a state where the card 26 is pushed down, 23b is adsorbed and held by the object to be adsorbed 24.

On the other hand, FIG. 1 shows the ON state of the delay switch of the present embodiment. When the handle 90 is turned off (set release operation) in this state, the tip of the arm pressing piece 90b is moved to the curved portion 50a of the arm 50. The arm 50 rotates so as to move away from the curved portion 50a along the axis, and the card pressing portion 52 of the arm 50 moves away from the pressed portion 26a of the card 26. When the handle 90 is turned off, the coil spring 96 is tilted in the direction opposite to that in FIG. 1 so that the movable contact 74 provided on the rocking body 73 is opened from the fixed contact 64b of the terminal plate 63b as shown in FIG. When the delay time described later elapses, the card 26 moves forward by the restoring force of the return spring 27, and the contact spring pressing portion 26c provided on the card 26 pushes the contact spring 70 forward (upward in FIG. 3). So
The movable contact 72 is separated from the fixed contact 64a, and this electric path (switch mechanism) is also turned off.

However, in the delay switch of the present embodiment, when the set is released by the handle 90, the suction cup 2
Since there is a delay time until the suction cup 23b separates from the suction target 24 due to the balance between the suction force of the 3b to the suction target 24 and the spring force of the return spring 27, the conventional gear is not required, and the conventional delay is required. Compared with a delay switch having a unit, the configuration is simpler, higher in reliability, lower in cost, and lower in noise.

Hereinafter, each component of the delay switch of this embodiment will be described in detail.

The case 1 of the delay switch is shown in FIGS.
As shown in FIG. 5, the body 10 made of synthetic resin and the cover 80 made of synthetic resin are connected to each other by a pair of substantially U-shaped assembly frames 40.

As shown in FIG. 4, shoulders 80b protrude from both ends of the cover 80, and recesses 80c into which the leg pieces 40d of the assembly frame 40 are fitted are formed on the side surfaces of each shoulder 80b. ing. On the other hand, on the front end side of the body 10, a concave portion 18 is formed at a portion corresponding to the concave portion 80c, into which the leg piece 40d of the assembly frame 40 is fitted.
Therefore, when the cover 80 is joined to the body 10, the assembly frame 40 is fitted from the front side of each shoulder 80b of the cover 80 (the leg 40d of the assembly frame 40 is attached to the cover 8).
0) and the concave portion 18 of the body 10), and a substantially V-shaped hooking claw 40a formed at the tip of both leg pieces 40d of the assembly frame 40 is formed on the step 15 formed on the side surface of the body 10, respectively. , The cover 80 and the body 10 are fixed by the assembly frame 40.

Here, up to three cases 1 can be attached to the mounting frame for the embedded wiring device in a manner that the front surface of the case 1 is exposed from the opening window of the mounting frame. Of embedded wiring equipment with unit dimensions set to
It is formed in a size corresponding to an individual. That is, the case 1 is formed to have a size of one wiring device that can be mounted on a single mounting frame of a large-sized continuous wiring device standardized by JIS, for example, up to three wiring devices. A pair of engaging claws 40 b capable of engaging with the mounting holes provided in the mounting frame are provided to project from both ends of the assembly frame 40. In other words, with respect to a mounting frame having an elongated window for mounting an appliance having three pairs of mounting holes, which are three appliance mounting means, the case 1 has an outer dimension in the short direction that is longer than the length of the opening window. It is formed in approximately 1/3 of the direction. Further, each assembly frame 40 is provided with a locking hole 40c in which a locking claw of the mounting frame is locked when mounted on a metal mounting frame.

The cover 80 is formed such that a part of the handle 90 for operation protrudes from the front surface of the case 1.
Opening 81 (see FIG. 4) for accommodating
As shown in FIGS. 4 and 5, a concave portion 82 is formed on the inner surface of the cover 80 so that a convex portion 95 protruding from both side surfaces of the handle 90 is engaged. Therefore, the handle 90
By inserting the projections 95 on both side surfaces of the handle 90 into the recesses 82 of the cover 80 when the handle 90 is stored in the opening 81, the recesses 82 of the cover 80 serve as pivot points for the handle 90.

On the other hand, as shown in FIGS. 4 and 6, a pair of triangular guide pieces 90a and a pair of semicircular arm pressing pieces 90b project from the side end of the rear surface of the handle 90. . Here, the distal end of each of the pair of arm pressing pieces 90b is adapted to engage and disengage with a curved portion 50a formed on the front side of the base end 50b of the substantially U-shaped arm 50. A transparent name cover 93 is fitted to the front of the handle 90. Name cover 93 and handle 9
A name sheet 94 (see FIG. 4) is sandwiched between 0 and 0.

The handle 90 has a light-transmitting window 91 formed at a predetermined portion of a portion protruding from the front surface of the case 1 in the state shown in FIG. 3, and a name sheet 94 has a portion facing the light-transmitting window 91 of the handle 90. Are provided with holes 94a (see FIG. 4). Here, the translucent window 91 is formed at a portion corresponding to the neon lamp 77 mounted on the circuit board 76 shown in FIG. 6, and a thin lamp cover portion 91 a for protecting the neon lamp 77 is continuous from the handle 90. It is formed integrally. The thickness of the lamp cover 91a is set so that the light of the neon lamp 77 can be transmitted to the outside. Therefore, the number of components can be reduced as compared with the case where a separate member for the lamp cover made of a translucent material is attached to the translucent window 91, and cost reduction can be achieved.

A gap is formed between the handle 90 and the cover 80. In this embodiment, the handle 90 is located between the handle 90 and the cover 80, as shown in FIGS. Since the overlap portion (flange portion) 90c that covers the formed gap extends, it is possible to prevent the arc accompanying the opening and closing of the contact from transmitting to the outside.

A recess 97 (see FIGS. 1 and 6) into which one end of the coil spring 96 is fitted is formed on the rear surface of the handle 90.
Is received between the spring supporting portions 75a and 75b of the rocking body 73. The oscillating body 73 is inclined in the direction opposite to the inclination direction of the handle 90 by the action of the coil spring 96 (see FIG. 1). The handle 90 is securely fixed at that position by a restoring force that is bent and the coil spring 96 tries to return to a straight state.

As shown in FIG. 4, the body 10 has a timer block storage section 12 formed substantially at the center, and terminal storage sections 13 and 14 formed on both sides of the timer block storage section 12. The timer block housing section 12 is housed timer block 20 to be described later, the terminal accommodating portion 14 terminals 60 ₁ to be described later, 60 ₂ is accommodated, the terminal 60 ₃ below the terminal accommodating portion 13, 60 ₄ housing Is done. Further, the front end of the body 10, a concave bearing portion 5 which rotary shaft 51 ₁ which protrudes from the proximal end 50b of the arm 50 described above, 51 ₂ is pivotally attached
5 ₁ and 55 ₂ are formed, and the arm 50 is rotatable.

Hereinafter, the timer block 20 will be described.

As shown in FIGS. 7 and 8, the timer block 20 has a substantially U-shaped card 26 and a guide groove 21b for guiding both legs of the card 26 when the card 26 moves.
The rectangular frame-shaped frame (middle frame) 21 on which (see FIG. 7A) is formed and the card 26 are moved forward (upward in FIG. 7B).
A return spring 27 made of a coil spring for urging, a sucker block 23 having a sucker 23b formed of rubber such as silicon rubber and capable of being elastically bent, and a regular octagon on which the sucker 23b is sucked To be adsorbed 24, an air permeable member 32a to be described later, a box-shaped element case 22 having a rear opening and containing the suction cup 23b and the object to be adsorbed 24, and a rectangle attached to the rear surface of the element case 22 And a plate-shaped dustproof filter 25.

As shown in FIGS. 9 to 13, the suction cup block 23 includes a suction cup 23b made of rubber such as silicon rubber and a polyamide resin (for example, nylon 66).
(See FIG. 14)
And are integrally formed.

The suction cup 23b has a cylindrical air permeable member 32.
a (see FIGS. 7 and 8) is formed continuously and integrally with a cylindrical air permeable member press-fit portion 23d into which the internal space 23f is press-fitted. Is provided.

Here, although the adhesive strength between the air permeable member press-fitting portion 23d of the suction cup 23b and the shaft 42 is low due to the difference in the material thereof, in the present embodiment, the rear surface of the shaft 42 (see FIG. Since the hatched portion is subjected to graining at the time of molding to form fine irregularities, it is possible to improve the adhesive strength between the shaft 42 and the air permeable member press-fitting portion 23d of the suction cup 23b with an adhesive or the like, The suction cup 23b and the shaft 42 can be firmly and reliably connected to each other, so that the durability reliability of the suction cup block 23 is improved.

Since the R is provided on the rear surface of the shaft 42, the adhesive is hardly cracked, and the adhesive strength is improved.

The suction cup 23b has a flange 23 on the suction surface side.
m is formed, and a parting line PL indicated by a dashed line in FIGS. 10 and 13 is provided in a portion other than the suction surface. Therefore, it is possible to prevent burrs from being generated on the suction surface due to molding of the suction block 23,
In addition, since it is possible to prevent the suction surface from being damaged when removing burrs, it is possible to stabilize the suction state of the suction cup 23b to the suction target 24 and to improve the accuracy of the delay time. . Further, in the present embodiment, as shown in FIG. 9C, FIG. 10 and FIG.
It is possible to prevent the suction cup 23b from sticking to the suction target 24.

In this embodiment, the air permeable member 32a is made of a porous ceramic, and the temperature dependence and humidity dependence of the air permeability coefficient are small. The delay time can be reduced, and the delay time can be increased.

By the way, in order to produce two types of delay switches having different delay times, two types of air permeable members 32a having different outer diameters (hereinafter, those having a smaller outer diameter are referred to as air permeable members 32a and larger outer diameters). Thing to air permeable member 32
b) is used in accordance with the delay time, and the suction block 23 can be shared by using the air permeable member press-fit portion 23.
It is conceivable to set the inner diameter of d according to the outer diameter of the air permeable member 32b having a larger outer diameter. In such a case,
In order to press-fit the air permeable member 32a having a small outer diameter, it is conceivable to press-fit the air permeable member 32a whose outer periphery is sealed with a rubber tube or the like into the internal space 23f of the air permeable member press-fit portion 23d. However,
In such a case, a separate member such as a rubber tube is required even if the suction block 23 is shared.

On the other hand, in the present embodiment, two types of air permeable members 32a and 32b having different outer diameters as shown in FIG. Press-fit portion 23f1 capable of press-fitting an air permeable member 32b of 2 mm, and first press-fit portion 23f
Air permeable member 32 having an inner diameter smaller than 1 and an outer diameter of 1 mm
Since the second press-fitting portion 23f2 capable of press-fitting a and the vent hole 23g having an inner diameter smaller than that of the second press-fitting portion 23f2 are formed along the press-fitting direction (downward in FIG. 15), a tube or the like is formed. There is no need to use Since the tapered portion 57 is formed on the press-in side of the first press-fit portion 23f1, the air permeable member 3
The press-fitting of the second press-fitting portion 23f2 can be reliably performed with a low load, and the tapered portion 58 is formed on the press-fitting inlet side of the second press-fitting portion 23f2. Can be reliably performed with a low load.

Here, in the delay switch using the timer block 20 in which the air permeable member 32a having an outer diameter of 1 mm is press-fitted into the second press-fit portion 23f2 of the suction cup block 23, the delay time is about 3 minutes. A delay switch using the timer block 20 in which the air-permeable member 32b having an outer diameter of 2 mm is press-fitted into the first press-fitting portion 23f1 has a delay time of about 30 seconds. In this embodiment, since the air permeable member 32a is used, the delay time is approximately three minutes.

The length of the suction block 23 along the press-fitting direction of the first press-fitting portion 23f1 is equal to that of the first press-fitting portion 23f1.
The length of the air permeable member 32b which can be press-fitted into f1 is set longer than the length of the air permeable member 32a which can be press-fitted into the second press-fit portion 23f2. Is also set long. Thus, when one of the air permeable members 32a, 32b is press-fitted, it is possible to prevent the air permeable members 32a, 32b from being pushed too far or too far, and to reduce the variation in delay time between products. Can be.

Further, the suction block 23 has an inner diameter larger than the inner diameter of the air permeable member press-fit portion 23d, and the air permeable member temporary holding space 56 capable of temporarily holding the air permeable member 32b when the timer block 20 is assembled. The air permeable member press-fit portion 23
The press-fitting of the air permeable member 32b into the internal space 23f of d can be performed efficiently and reliably. Here, if the air permeable member temporary holding space 56 is provided in the air permeable member press-fitting portion 23d, slippage at the time of press-fitting is poor and it is difficult to press-fit the air permeable member 32b. Of the air permeable member temporary holding space 56, even when the air permeable member 32b is press-fitted, the initial slip is good at the time of press-fitting and the insertability is improved.

The suction block 23 has an opening on the side opposite to the suction surface of the suction cup 23b, and separates the dust cover 23 between the suction surface of the suction cup 23b and the outside of the element case 22.
a is formed continuously and integrally with the suction cup 23b. The dust cover 23a has a flange 23c formed at the open end (front end) over the entire circumference. The flange 23c is formed in the element case 22 and has a press-fit recess 22g described later.
Press-fit.

The flange 23 of the dust cover 23a
When the entire circumference of c is press-fitted, there is a possibility that a part that cannot be press-fitted may occur. Since the chamfered portion is formed, the end of the dust cover 23a is pressed into the press-fitting recess 22g of the element case 22.
The insertability at the time of press-fitting into the (press-fitting portion) is improved, and the entire circumference of the end portion (the flange portion 23c) of the dust cover 23a can be easily press-fitted with a small force. In addition, ribs 23e are continuously and integrally protruded from key portions of the flange portion 23c.

The suction cup block 23 includes the suction cup 23b described above.
And dust cover 2 formed continuously and integrally with suction cup 23b
3a and a shaft 42. Further, the air permeable member press-fitting portion 23d forms an air introducing portion.

In this embodiment, the dust cover 23
Since the suction cup 23b and the outside of the element case 22 are separated by a, it is possible to prevent foreign matter such as dust from entering between the suction cup 23b and the to-be-adsorbed body 24.
The adsorbed state between the object and the object 24 is stabilized, and the delay time can be made substantially constant.

Next, the relationship between the suction cup block 23 and the card 26 will be described.

The shaft 42 of the sucker block 23 has a pair of rod-shaped card holding pins 4 on its outer periphery that are substantially parallel to the axial direction.
2b are formed continuously and integrally. To couple the shaft 42 to the card 26 (see FIGS. 7 and 8), the shaft 42 is inserted from the rear into an insertion hole 22e formed on the front surface of the element case 22 (see FIGS. 7 and 8). The leading end of each card holding pin 42b is inserted into the insertion hole 26d formed on both sides of the contact spring pressing portion 26c at the base end 26f of the card 26, and the leading end of the card holding pin 42b is irradiated with laser light or the like. It is caulked by heating and melting (heat caulking is performed).

Here, there is a possibility that the frame 21 and the card 26 may be melted by the laser beam when the tip of the pin 42b for holding the card of the shaft 42 is caulked. (Nylon 66 is colored black with a pigment), and the frame 21 and the card 26 are colored white, which is harder to absorb the laser light than the color of the shaft 42. Can be efficiently absorbed, and the melting of the frame 21 and the card 26 by the laser beam can be prevented.

In the present embodiment, since a chamfer (not shown) is provided on the periphery of the insertion hole 22e on the front surface of the base end portion 26f of the card 26, heat caulking accumulates in the chamfer and the caulking strength is obtained. Is improved. Also, card 2
In No. 6, since the flat portion 26aa is provided at a key portion of the pressed portion 26a, the release pin is easy to install and easy to remove during molding.

In this embodiment, the card 26 and the shaft 4
2 is coupled, the sucker block 23 moves in accordance with the movement of the card 26, and a state in which the sucker 23 is attracted to the attracted body 24 (see FIG. 1) and a state in which the sucker 23 is not attracted (see FIG. 3). Changes the shape of the suction cup 23.

By the way, at the rear of the base end 26f of the card 26, the internal space 23f of the air permeable member press-fitting portion 23d and the card 2
An air intake port 26e is formed by a cut-out portion that forms an air passage between the air inlet 6 and the outside of the air inlet 6. Further, the suction block 23 is provided on the inner peripheral bottom surface of the suction cup 23b.
f and a ventilation hole 23g (see FIG. 1 and FIG. 3) communicating with the air intake port 2b.
6e. Thus, in the present embodiment, when the suction cup 23b is adsorbed to the suction target 24, air is introduced into the space formed between the suction cup 23b and the suction target 24 through the air permeable member 32a.

As shown in FIGS. 7 and 8, on the front surface of the element case 22, a return spring 2 is provided around the insertion hole 22e.
7 is formed with a spring receiving groove 22b into which one end is fitted. On the other hand, a pair of substantially concave spring receiving grooves 26b (see FIG. 8) are formed on the rear surface of the base end 26f of the card 26 so as to hold the other end of the return spring 27. Since the spring receiving groove 26b has a chamfered portion (not shown) formed at the periphery of the opening, the return spring 27 can be easily inserted.

Incidentally, the timer block 20 includes the suction cup 2
In the space formed between the suction cup 23b and the to-be-adsorbed body 24 in a state where 3b is adsorbed to the to-be-adsorbed body 24, the air that enters the internal space 23f from the air intake 26e of the card 26 is an air permeable member. The suction hole 23b enters through the vent hole 23g of the suction cup 23b through 32a. Therefore, the card pressing portion 52 composed of both legs of the arm 50 (see FIG. 1) is replaced with the pressed portion 26 a composed of both legs of the card 26.
Away from the tip end, the suction force of the suction cup 23b to the suction target 24 gradually decreases, and the suction force becomes weaker than the restoring force of the return spring 27, and the suction cup 23b separates from the suction target 24.

That is, when the handle 90 is turned off (set release operation), the distal end of the arm pressing piece 90b (see FIG. 1) is disengaged from the curved portion 50a along the inner peripheral surface of the curved portion 50a of the arm 50. To move the arm 5
0 after a predetermined time (delay time) from the point at which the zero card pressing portion 52 leaves the pressed portion 26a of the card 26.
Moves forward (upward in FIG. 1). Therefore, the air permeability and size (outer diameter and length) of the air permeable member 32a, the material of the suction cup 23b, and the
The delay time can be adjusted by changing the material of No. 4 and the like.

The frame 21 is made of, for example, a polyamide resin (for example, 66 nylon). As shown in FIG. 16, a positioning projection 21c for the body 10 projects from the front end to the rear end of each side surface. ing. On the other hand, as shown in FIGS. 4 and 17, the body 10 is provided with a positioning groove 16a for guiding the positioning projection 21c on the inner side surface of the timer block storage portion 12, so that the timer Reverse insertion of the block 20 can be prevented.

The frame body 21 has a rib 21k for press-fitting into the body 10 protruding from a surface facing the inner side surface of the body 10, and is press-fitted into the body 10, so that the timer block 20 is assembled during assembly. 10 can be prevented from floating from the bottom surface, and assemblability can be improved.

The frame 21 has the guide groove 21b formed on the inner surface thereof for guiding the pressed portion 26a (both leg pieces) of the card 26 so that the timer block 20 is assembled. 7B, the tips of the pressed portions 26a, 26a of the card 26 project from the front surface of the frame 21 as shown in FIG. 7B. The card 26 is provided with a pair of reverse insertion preventing ribs 2 for preventing a trouble of being inserted in the opposite direction when the card 26 is inserted into the frame 21.
6g (see FIGS. 7A and 8) protrudes from the base end 26f.

As shown in FIGS. 7 and 8, the frame body 21 and the element case 22 are arranged in front of the element case 22 at a position between the four corners of the element case 22 and the spring receiving groove 22b.

Here, if the extension piece 63aa is bent perpendicularly from the terminal plate 63a, the extension piece 63aa and the contact spring 70a are in a state where the movable contact 72 is in contact with the fixed contact 64a.
Are not parallel to each other, and when the fixed contact 64a and the movable contact 72 are consumed, the centers of the two contacts 64a and 72 may shift without contact with each other, and may not satisfy the opening / closing performance. The movable contact 72 is a fixed contact 64
a so that the extension piece 63aa and the contact spring 70 are substantially parallel to each other with the extension piece 63a being in contact with the terminal plate 63a.
Since the bending angle of aa is set, the tangency between the extended piece 63aa and the contact spring 70 is maintained, and the opening / closing performance is improved.
Life is also improved. In short, even when the fixed contact 64a and the movable contact 72 are worn, the centers of the two contacts 64a and 72 are in contact with each other, so that the deterioration of the switching performance can be prevented.

By the way, as shown in FIG. 16, the frame 21 is provided on one side with the leg portions 6a of the terminal plates 63a and 63b.

Insulation wall 49 between terminals for preventing deterioration of insulation performance between terminals
Is provided between the terminal plate leg receiving portions 46 ₁ and 46 ₂ ,
The insulation performance between the terminals 60 ₁ and 60 ₂ can be improved.

The element case 22 is formed of, for example, PBT or the like, and as shown in FIG. Since the length is made substantially uniform, molding defects such as sink marks can be prevented. The element case 22 is provided between the peripheral wall of the spring receiving groove 22b and the inner surface of the element case 22 by a flange 23 of a dust cover 23a.
A press-fit recess 22g (see FIG. 7B) into which c is press-fitted is formed in an annular shape.

By the way, at the rear of the element case 22,
A press-fit portion (not shown) into which the to-be-adsorbed body 24 is press-fitted is formed. When the timer block 20 is assembled, the to-be-adsorbed body 24 is pressed into the press-fit portion of the element case 22. Are temporarily fixed to the element case 22, and the mounting of the filter 25 is facilitated. The press-fit portion is provided with a press-fit rib (not shown) that presses against the side surface of the to-be-adsorbed body 24. Also, since the shape of the object to be adsorbed 24 is a regular octagon as shown in FIG. 20, a large bonding area of the filter 25 can be secured with respect to the element case 22 having a square bottom surface. 22 can be reduced in thickness, and the strength of the element case 22 can be increased. Here, the filter 25 is composed of an adhesive layer 25
It is adhered to the rear surface of the element case 22 via a. In addition, since the to-be-adsorbed body 24 is formed in a regular octagon, when the to-be-adsorbed body 24 is pressed into the press-fitting portion of the element case 22, there is little restriction on the direction in the plane of the to-be-adsorbed body 24. The assemblability is improved.

Since the to-be-adsorbed body 24 is formed of a fluororesin (Teflon resin) such as PTFE, for example,
Since the surface roughness and the coefficient of friction of the to-be-adsorbed body 24 can be reduced, and the abrasion of the to-be-adsorbed surface to which the suction cup 23b is adsorbed can be suppressed, the fluctuation of the delay time can be prevented. Further, by forming the to-be-adsorbed body 24 by punching a flat plate, the cost can be reduced as compared with the case where the to-be-adsorbed body 24 is formed by molding. Moreover, since the both sides in the thickness direction of the to-be-adsorbed body 24 have the same finish, there is no need to distinguish between the front and back sides, and it is not necessary to prevent reverse assembly, so that the assemblability is improved. Note that a portion of the timer block 20 excluding the frame 21 forms a delay element.

At the rear of the handle 90, a neon lamp 77 and a resistor 79, which are display elements, are mounted on a circuit board (printed wiring board) 76 as shown in FIGS. A display element block 7 is provided (see FIGS. 1 and 6), and one lead of the neon lamp 77 is connected to one end of a resistor 79. The other end of the resistor 79 is connected to the return spring 27 via a contact 78b made of a leaf spring.
Here, one end of the contact 78b is arranged near the bottom surface of the concave portion 97 (see FIG. 6) formed in the handle 90, and is electrically connected to the return spring 27. The other lead of the neon lamp 77 is a contact 78a made of a leaf spring.
Is electrically connected to That is, the contact 78a, the neon lamp 77, the resistor 79, and the contact 78b are connected in series. By the way, the contact 78a is attached to the terminal plate 63a in accordance with the operation of the handle 90.
c (see FIG. 4).
8a is in contact with the contact 78c in the OFF state of the delay switch (see FIG. 3), and is in the ON state of the delay switch (FIG. 1).
) Is separated from the contact 78c. The contact 78a and the contact 78c constitute an energizing unit.

Here, the return spring 27 is connected to the terminal plate 63.
c, the power to the neon lamp block 7 can be obtained via the return spring 27 and the contact 78b. Since the contact 78b is made of a leaf spring and has a small thickness, the thickness of the contact 78b is sufficiently smaller than the length of the return spring 27, and the influence on the operation load of the handle 90 is small.

In this embodiment, since the contact 78a is brought into contact with the contact 78c, the length of the contact 78a is reduced as compared with the case where the contact 78a is brought into direct contact with the terminal plate 63a. Can be a circuit board 76
The length of the contact 78a protruding from the lamp block becomes short, so that the neon lamp block 7 is easily assembled and the neon lamp block 7 is easily handled.

[0084] Incidentally, the contact 78c, as shown in FIGS. 1 and 25, since the first leg portion 78c _1, which is sandwiched between the surface and the terminal plate 63a of the cover 80 is provided,
The contact 78c can be prevented from falling down after assembly. Further, as shown in FIG. 25, the contact 78c is a second foot 78 for temporarily fixing to the terminal plate 63a during assembly.
Because c ₂ is provided, at the time of assembly, the terminal plate 63a
A second leg portion 78c ₂ will be entering the gap between the terminal plate leg receiving portions 46 ₁ of the frame 21, it is possible to prevent the falling over contact 78c during assembly.

The neon lamp 77 is

Therefore, in the off state of the delay switch of the present embodiment, the position of the case 1 can be visually recognized by the light of the neon lamp 77 even when the surroundings are dark such as at night.

[0086] When used in the operation of the delay switch, for example, toilet ventilation fan and the lighting load of the present embodiment described above, since the terminal 60 ₃ and the terminal 60 ₄ have a common terminal plate 63c, the terminal 60 ₂ Connect the lighting load to
0 may be connected to a ventilation fan to _1. In this case, handle 9
When 0 is turned on (set operation), the lighting load is turned on and the ventilation fan is operated, and when the steering wheel 90 is turned off (set release operation), only the lighting load is turned off immediately and the ventilation fan is stopped after the delay time has elapsed. . Therefore, eliminating the inconvenience that occurs when the ventilation fan is stopped immediately,
Moreover, forgetting to turn off the ventilation fan can be prevented. Here, when the handle 90 is turned off, the contact 78
Since a contacts the contact 78c connected to the terminal plate 63a, the neon lamp 77 is turned on. The delay switch can be used in various places other than the toilet. Further, the delay time may be appropriately set according to the use environment and the purpose of use.

This embodiment is different from the first embodiment in that the terminal plate 63b and the fixed contact 64b described in the first embodiment are not provided, and the shape of the terminal plate 63a and the shape of the oscillator 73 are different from those of the first embodiment. Further, in the present embodiment, the timer block 20
As shown in FIG. 31, an air permeable member 32b having an outer diameter of 2 mm is press-fitted into a first press-fit portion 23f1 of the suction cup block 23. In short, in the present embodiment, the delay time described in the first embodiment is set to approximately 30 seconds. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

The oscillating body 73 in the delay switch of this embodiment has a substantially U-shape as shown in FIG.
There is no bent piece 73b (see FIG. 1) as in the first embodiment, and no movable contact 74 is provided.

Next, the operation of the delay switch of this embodiment will be described.

FIG. 28 shows the OFF state of the delay switch of this embodiment. In this state, when the handle 90 serving as the operating portion is turned on (set operation), the arm pressing piece 90b of the handle 90 is rotated, and the arm pressing piece is turned. The distal end of 90 b moves along the curved portion 50 a of the arm 50. When the handle 90 is turned on, the coil spring 96 is tilted in the opposite direction, and the arm 50 is rotated by the arm pressing piece 90b, and the card pressing portion 5 at the tip of the arm 50 is turned.
2 presses the pressed portion 26a of the card portion 26, and the return spring 2
The card 26 moves against the urging force of the contact spring 7 (pressed down in FIG. 28), and the movable contact 72 of the contact spring 70 is moved.
Contacts the fixed contact 64a of the terminal plate 63a, and this electric path is turned on. Further, when the card 26 moves, the suction cup 23b is pushed down to a position where the suction cup 23b comes into contact with the suction target 24, and the suction cup 23b is sucked to the suction target 24,
When the card 26 is pressed down, the suction cup 23b
Is adsorbed and held by the object to be adsorbed 24.

FIGS. 26 and 27 show the ON state of the delay switch of this embodiment.
Is turned off (set release operation), the arm pressing piece 9
0b moves along the curved portion 50a of the arm 50 so as to be detached from the curved portion 50a.
0 rotates, and the card pressing portion 52 of the arm 50
6 moves away from the pressed portion 26a. When the handle 90 is turned off, the coil spring 96 is tilted in the reverse direction. After the delay time described above, the card 26 is moved forward by the restoring force of the return spring 27, and the contact spring pressing portion 26c is moved by the contact spring 70c. Is pressed forward, the movable contact 72 is separated from the fixed contact 64a, and this electric path (switch mechanism) is turned off.

When the delay switch of the present embodiment is used for operating a lighting load at, for example, an entrance, a terminal 60 is used.
_A lighting load may be connected between ₁ and the terminal 60 ₃ (or the terminal 60 ₄ ). In this case, when the steering wheel 90 is turned on (set operation), the lighting load is turned on, and when the steering wheel 90 is turned off (set releasing operation), the lighting load is turned off after the elapse of the delay time. Therefore, for example, when turning off the steering wheel 90 after turning on the lighting load when going out or returning home, there is a delay before the lighting load is turned off, so the lighting load is turned off before the person leaves the entrance. It is possible to eliminate such inconvenience.
