Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to operation switches for rotary switches, push-pin switches, etc., and more specifically, selector switches, push-button switches, lock-lock switches, and turn-lock push buttons. This invention relates to an operating mechanism that can be commonly used for switches and the like.

Conventional operation switches have different designs for different models, each using its own parts, which has the drawback of requiring a large number of parts, complicating production management, and increasing manufacturing costs.

In addition, each part is connected and fixed by screwing, caulking, etc., which has the disadvantage that assembly work requires a lot of man-hours. The present invention is related to the invention of an operation switch that can be assembled without using screws or caulking as means for connecting members, and is an operation mechanism in which each member is interconnected by iron fitting. The purpose of the present invention is to provide an operating mechanism that can be used commonly for various operation switches with different functions, such as select switches, pusher switches, locking pusher switches, and turn-lock pusher switches. .

Hereinafter, the present invention will be explained based on drawings of embodiments.

FIG. 1 is a front view of a presser switch according to the present invention, and FIG. 2 is a longitudinal sectional view thereof.

This switch is composed of the following members.

That is, the operating part main body 1 has a cylindrical front part, a box-shaped rear part, and a through hole formed in the center, and a mounting ring 2 that is press-fitted or integrally formed on the outer periphery of the cylindrical front part of the operating part main body 1. , a head presser 3 that is loosely placed around the outer periphery of the mounting ring 2 and applies a forward pressing force by a compression spring, a round ring 4 that is pressed and connected to the front edge of the mounting ring 2, and a central through hole of the operating section main body 1. An operating shaft 5 that is iron-coupled and can freely slide forward and backward and in the circumferential direction, a compression spiral spring 6 that presses the operating shaft 5 forward, a pusher 07 that is fitted into the front green of the operating shaft 5, and the operating shaft 5.
A press plate 8 is fitted into the rear end of the switch body 9, and a follower 10 is displaceable when it comes into contact with the press plate 8, which protrudes forward in the center of the switch main body 9, which is fitted into the rear end of the operating section main body 1. , a bridge piece 11 provided via a spring from the follower 10 and equipped with a movable contact, terminal screws 12, 12 fixed to the switch main body 9,
It is composed of fixed terminals 13, 13, etc., which are suitable for terminal screws. In addition, each member, except for the helical spring, terminal screw, contacts, and conductor, is made of plastic resin such as polyacetal, polycarbonate, and nylon.
This pusher switch is attached to a circular hole in a panel P with the panel P sandwiched between a hook 14 formed on the front edge of the attachment ring 2 and the head holder 3.

Furthermore, when the operating shaft 5 is displaced by the push of the push pin 7, the push plate 8 displaces the follower 10 backward, and the bridging piece 11 short-circuits the fixed contacts 13, 13 to turn on, and the push button 7 is pressed. When released, the operating shaft 5 returns to its original position due to the spring 6, and the follower 10
also returns to the off state. FIG. 3 shows a rear view of the operating section main body.

Hook insertion holes 22, 22 are formed in the center of the short sides 21, 21 of the rectangle for connection with the switch main body 9, and
Spaces 23 are formed at the four corners, and members or devices corresponding to the functions of the operation switch can be selectively attached to these spaces 23. FIG. 4 shows a perspective view of the rear end of the operating shaft 5. As shown in FIG.

Cut grooves 28, 28 are formed at two opposing locations on the rear end, square holes 29, 29 are formed at two locations separated by 90 degrees, and a member corresponding to the function of the operation switch is formed at the rear end. can be selectively attached using iron inlay connections. FIG. 5 shows an exploded perspective view of the operating mechanism of the selector switch embodying the present invention. Operation axis 5
The operating cam 31, which is connected to the rear end by iron fitting instead of the pressing plate 8 shown in FIG. A cylindrical cam 33 is formed. In addition, notch members 34 and 34 and bell seals 35 and 35 for pressing the notch members against the corrugated portion 32 are attached to opposing spaces 23 of the operation section main body 1. FIG. 8 is a rear view of the operating section main body 1 in a state in which the /ch member 34 is attached to the space 23 and the operating cam 31 is connected to the operating shaft 5. The notch portion 34 with the spring 35 inserted into the hole 36 is connected to the opposing spaces 23 and 2 of the operating portion main body 1.
The notch member 34 is attached to the wall of the operating cam 31 while being biased in the radial direction via a spring 35, and the notch member 34 elastically competes with the corrugated portion 32 of the operating cam 31. To explain the assembly order, first insert the spring 35 into the hole 36 of the notch member 34. Next, spring 3
The notch member 34 into which the notch 5 is inserted is housed in a pair of opposing spaces 23 of the operating section main body 1. Next, the operation cam 31 is housed in the operation section main body 1. In this case, the neck of the notch member 34 is positioned at the trough of the wavy portion 32 of the operating cam 31. Next, insert the operating shaft 5 into the operating cam 31 from the front.
In the case of a selector switch, the operating shaft spring 6 is not used, and instead of the push button 7, an arrow-shaped handle or the like is used.
The function of this embodiment is that the follower 10 in contact with the cylindrical cam 33 is displaced in accordance with the rotational angular position of the operating shaft 5, thereby turning the switch on and off.

In addition, the operation cam 31 remains stably stationary with the notch member 34 recessed into the valley of the corrugated portion 32. FIG. 6 shows the operating mechanism of a lock-type push-button switch according to the present invention, and FIG. 9 shows a rear view of the operating section main body 1 incorporating each member of the operating mechanism of the lock-type push-button switch.

A flange portion 42 is formed over a predetermined angular range on a press plate 41 that is fitted with iron at the rear end of the operating force 5. Further, a hooking claw device 43 is attached to the opposing space portions 23 of the operation section main body 1. The hook device 43 includes a leaf spring 45 and a hook 46 in a rectangular housing 44, and the hook is displaced about a cylindrical support shaft 47 formed at one end of the hook 46 as a fulcrum. When the flange portion 42 hits from the direction of arrow A, the hook 46 moves from the roller along the slope to the press plate 4.
1 can be displaced by climbing over the hook 46. Conversely, when the flange portion 42 hits from the direction of arrow B, the hook 46 hangs on the vertical surface of the flange portion 42, preventing the pressing plate 41 from returning. . In the case of a lock type push button switch, an operating handle such as an arrow-shaped handle or a mushroom-shaped handle is used instead of the push nail 7.

The function of this embodiment is that when the operating handle is pressed and displaced, the pressing plate 41 turns on the switch, and at that time, the flange portion 42 rides over the hook 46, so even if the pressing force of the operating handle is released, the operation can be continued. The shaft 5 cannot be returned and is locked in the on state.

Next, when the operating handle is rotated until the notch in which the flange portion 42 is not formed comes to the position of the hook, the return displacement of the flange portion 42 is allowed and the switch returns to the OFF state.
The operating shaft 5 is returned to its original state in both the ball direction and the rotating direction by the operating shaft spring 6. Furthermore, in FIGS. 6 and 9,
In order to prevent the operating shaft 5 from rotating excessively after the locked state is released, a stopper 48 may be provided in the other space 23 of the operating section main body 1. FIG. 7 shows an exploded perspective view of the operating mechanism of the turn-lock type presser switch embodying the present invention.

Further, FIG. 10 shows a rear view of the main body 1 of the operating section incorporating parts such as the pressing plate 51 and the guide plate 54 in the operating mechanism of this turn-lock type push-pin switch. A flange portion 53 is formed on the entire circumference of the press plate 51, which is fitted with iron at the rear end of the operating shaft 5, except for notches 52 provided at two opposing locations. In addition, the opposing space portions 23 of the operation unit main body 1
A guide pin 54 is attached to. The mechanism of this embodiment is such that when the operating handle is pressed, the notch 52 of the pressing plate 51
is displaced along the guide pin 54, and the switch is turned on.

When the pressure on the handle is released, the pressure plate 51 returns along the guide pin 54 again due to the force of the operating shaft spring 6, and the switch returns to the OFF state. However, if the operating handle is rotated while being pressed, the flange portion 53 will move against the guide pin 5.
4, and even if the pressing force is released, the operating shaft 5 will not return to its original position. In other words, the switch is in a locked state. When the rotational position of the operating handle is returned to its original position, the switch returns to the off state. According to the present invention, spaces in which various members or devices can be attached are provided at the four corners of the box-shaped portion of the operating unit main body, and means for fitting and coupling various members are provided at the rear end of the operating shaft, and the spaces in the four corners are provided. By selectively attaching a notch member, latch device, stopper, guide pin, etc. to the rear end of the operating unit, and selectively combining an operating cam and a pressing plate of various shapes to the rear end of the operating unit, it is possible to create a push-pin switch, a lock, etc. We can make various operation switches such as push nail switches, turn/lock push button switches, and selector switches.

Therefore, the number of parts and manufacturing costs can be significantly reduced, and inventory management becomes easier. In addition, each member is connected by fixing means such as press-fitting or hammering, and no screwing, caulking, etc. are used, making assembly work extremely easy.
