Description

[Detailed description of the invention] The present invention is a pulse switch that turns on a switch part for one pulse during reciprocating motion in one direction, and turns it off during movement in the other direction, for example, It relates to one-way switches and two-way switches. The pulse switch is used, for example, as a switch for operating a solenoid or motor of a vehicle locking device.

A conventional pulse switch, for example, a two-way switch, has two switch sections, and only one switch section turns ON for one pulse during reciprocating movement in one direction, and turns ON for one pulse during movement in the other direction. is one in which only the other switch part is turned on for one pulse,
As shown in FIG. 1, its configuration includes a shaft 1 to which a protrusion 2 is fixed, a first rocking body 4 that is pivotally supported by a torsion spring 3 in a case (not shown), and The second shaft is pivotally supported and whose swing is restricted by a torsion spring 5.
It is composed of an oscillator 6, a first switch section made up of contacts 7 and 8, and a second switch section made up of contacts 9 and 10. This is because when the shaft 1 is moved in the direction of the arrow A, the protrusion 2 engages with the protrusion 6a formed on the second rocking body 6, causing the second rocking body 6 to swing outward. 2 Switch part ON-OFF
let Furthermore, when the shaft 1 is moved in the direction of the arrow B, the rear surfaces of the protrusions 2 and 6a engage with each other, so the first rocking body 4 swings, and the protrusion 4a formed on the first rocking body 4 moves into the first rocking body 4. 1 switch part was to be turned on and off. However, this has a complicated structure, and furthermore, depending on the state of engagement between the protrusions, the operation of each switch part becomes uncertain and requires extremely high precision.

The present invention has been devised in view of the above-mentioned drawbacks, and its purpose is to provide an internal movable element and an external movable element that is loosely fitted with the internal movable element so that the internal movable element can slide slightly, in order to mutually shift their movement timings. The purpose of the present invention is to provide a small-sized pulse switch which has a simple structure and a stable switching operation state by temporarily sliding the movable contact and the fixed contact to open and close each time the switch is reciprocated.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The first embodiment will be explained as a two-way pulse switch based on FIGS. 2 to 5. Reference numeral 11 denotes an internal movable element formed into a substantially rectangular flat plate, and an engaging protrusion 11a that engages a rotating body 12, which will be described later, is provided on the upper surface of the internal movable element.
is formed. Reference numeral 13 denotes a movable contact made of an elastic body and formed in a substantially chevron shape, and has contact portions 13a and 13b at both ends that slide to open and close with fixed contacts 17 to 19, which will be described later. are doing. The movable contact 13 is separated into two parts on both sides in order to fully exhibit its elasticity. 14 is an external movable element, which includes two side walls 14a having the same shape and spaced apart from each other at a predetermined interval, and the side walls 14a.
The movable contact 13 is integrally formed with two lifting parts 14b and 14c that connect the movable contact 13 and regulate the conduction state of the movable contact 13. The upper surface of the side wall 14a has a notch 14d that is longer than the length _X1 of the internal mover 11 by a predetermined distance _Y1 , into which the mover 11 is loosely fitted so as to be movable by the predetermined distance _Y1 . ing. Above 2
The two lifting parts 14b and 14c are formed at the same position as the lower surface of the side wall 14a and spaced apart from each other so as to make contact with the movable contact 13. 15 is a box-shaped case with an opening at the top, and a printing board 1 is placed at the bottom of the case.
6 is fixed thereto, and a through hole 15a for pivotally supporting the rotation pin 47 is formed on the side surface. Printing base 16
has three fixed contacts 17, 18, 19 printed on it, and each end has terminals 20, 21,
22. Furthermore, the bottom of the case 15 holds four guide portions 15b that regulate the moving direction of the external movable element 14, and a substantially mountain-shaped leaf spring 23 that presses against the external movable element 14 to provide sliding resistance. A spring holding portion 15c is formed. Two protrusions 14e are formed on the outer surface of one side wall 14a of the external movable element 14 to engage with the leaf spring 23 and provide moderation of movement of the external movable element 14. Reference numeral 12 denotes the aforementioned rotating body, one end of which is fitted into the head 47a of the rotating pin 47, and the other end formed with a long hole 12a to engage with the engagement protrusion 11a of the internal movable member 11;
The internal mover 11 is moved left and right. A lever 26 is fixed to the tip of the pivot pin 47 through a packing 24 and a packing holding plate 25 at a position where it projects outward from the case 15.

Therefore, the internal movable element 11 and the external movable element 14 are moved left and right by rotating the lever 26. 27 is a lid that is covered with a gasket 26 interposed therebetween.

The operation of the first embodiment will be explained.

If the lever 26 is now in the position shown in FIG. 3, the internal mover 11, the external mover 14, and the movable contact 13 will be held in the state shown in FIG. That is, the internal movable element 11 and the external movable element 14 are in a state of being pressed against the inner wall surface of the case 15 by the rotating body 12. At this time, the left side of the movable contact 13 in FIG.
is separated from the printed circuit board 16. Therefore,
The contact portion 13a on the opposite side is in conduction only with the fixed contact 17.

Thereafter, the lever 26 is rotated to the position shown by the imaginary line in FIG. When the lever 26 begins to rotate, the internal movable element 11 moves into the notch 1 formed in the side wall 14a of the external movable element 14, as shown in FIG.
4d to the left by a predetermined distance _Y1 . Therefore, the movement timings of the two movable elements 11 and 14 are shifted from each other. Along with this, the movable contact 13 also moves to the left, and the external movable element 1
The relative positional relationship of 4 with the lifting parts 14b and 14c also changes. Therefore, the movable contact 13 lifting part 14b
, one contact portion 13a separates from and opens from the printed circuit board 16, and the other contact portion 13b comes into contact with the printed circuit board 16. When the internal movable element 11 moves to the left for longer than the predetermined interval _Y1 , the external movable element 14 also starts to move to the left, and the contact portion 13b slides on the surface of the printed circuit board 16, and the fixed contacts 17, 19
The lever 26 is moved to the third
When it rotates to the position shown by the imaginary line in the figure, the 6th
It becomes the position shown by the imaginary line in the figure, and conducts only with the fixed contact 17, and maintains that state.

This operation is similar when moving to the right. Next, a second embodiment will be explained as a two-way pulse switch based on FIGS. 7 to 9. Reference numeral 28 designates an internal movable element having a substantially rectangular parallelepiped shape, and has a guide portion 28a formed by extending both side walls on its upper surface, and a recessed portion 28b formed on its lower surface, having the same configuration as the first embodiment shown in FIG. The movable contact 13 is fixed. Reference numeral 29 denotes an external movable element, which is formed into a substantially box shape with an upper opening, and an internal space 29a thereof is longer by a predetermined distance _Y2 than the length _X2 of the internal movable element 28;
Further, the width is determined to such an extent that the internal movable element 28 can be loosely fitted therein. In addition, the lower surface of the external movable element 29 is the movable contact 1.
The opening is slightly larger than the width dimension of the movable contact 13, and a lifting portion 29b is formed near the center of the opening to regulate the conduction state of the movable contact 13. Therefore, the internal mover 2
8 is loosely fitted into the internal space 29a of the external movable element 29 so as to be movable by a predetermined distance _Y2 . still,
The length of the lifting portion 29b is determined to be approximately enough to make contact with the movable contact 13. Reference numeral 30 denotes an operating shaft, which is fitted and fixed to one end of the movable element 28, and is reciprocated from side to side to operate the two movable elements 28, 29.
operate. Reference numeral 31 is a box-shaped case that is open at the top, and a printing board 32 is fixed to the bottom of the case. The printing board 32 has three fixed contacts 33, 3
4, 35 are printed and their respective ends are connected to respective cords 36, 37, 38. Additionally, four guide portions 31a are formed at the bottom of the case 31 to restrict the moving direction of the external movable element 29. The guide portion 31a is provided with a substantially mountain-shaped plate spring 39 that presses against the external movable element 29 to provide sliding resistance.
is held. 40 is two movers 28, 29
It is a guide plate that prevents the material from floating upward.
Both ends thereof are fitted into the engagement holes 31b of the case 31 and fixed. The operating shaft 30 passes through the hole 31c of the case 31 and the hole 29c of the external movable element 29, and projects to the outside of the case 31. 41 is a lid that covers the upper surface of the case 31.

The operation of the second embodiment will be explained.

The two movers 28 and 29 are now pressed against the inner wall surface of the case 31 by the operating shaft 30, as shown in FIG. At this time, the left side of the movable contact 13 in FIG.
has separated from the printed base. Therefore, the movable contact 13a on the opposite side is in conduction only with the fixed contact 33.

Thereafter, the operating shaft 30 is pressed in the direction of the arrow E. At the beginning of pressing the operation shaft 30,
Similar to the operation of the first embodiment, since only the internal movable member 28 moves to the left, one contact portion 13a of the movable contact 13 separates from the printed circuit board 32, and the other contact portion 13b comes into contact with it. Furthermore, the contact part 1
3b is the fixed contact 3 as the external mover 29 moves.
3 and 35, and when the movement is completed, conduction is established only with the fixed contact 33, and this state is maintained. This operation is similar when operating the operating shaft 30 in the direction of the arrow F.

In the above two embodiments, it is also possible to form a lifting portion on the internal movable element and to fix the movable contact on the external movable element. For example, Figures 10 and 11
The third embodiment shown in the figure is a modification of the second embodiment. Components having the same configuration as those in the second embodiment are given the same reference numerals, and their explanation will be omitted.

Reference numeral 42 denotes an internal movable element, which is formed into a substantially box shape with openings at the top and bottom, and a movable contact 1 near the center of the bottom surface.

Reference numeral 43 denotes an external movable element, which is formed in a substantially box shape with an opening at the bottom, and its internal space 43a is longer than the length _X2 of the internal movable element 42 by a predetermined distance _Y2 . A fixing portion 43b for fixing the movable contact 13 is formed on the top surface of the external movable element 43. Reference numeral 46 denotes a guide plate that prevents the two movers 42 and 43 from floating up, and its both ends are fitted into the engagement holes 31b of the case 31 and fixed. The internal movable element 42 is loosely fitted into the internal space 43a of the external movable element 43 so as to be movable left and right, and the operating shaft 30 is inserted into the hole 31c of the case 31 and the external movable element 4.
It is inserted through the notch 43c of No. 3 and fixed.
In this case, the movable contact 13 is regulated by the lifting portion 42a in a direction opposite to that of the above two embodiments. That is, in the state shown in FIG. 10, one contact portion 13a of the movable contact 13 separates from the printed board 32, and the other contact portion 13b comes into contact.

The operation of the third embodiment is the same as that of the second embodiment, so a description thereof will be omitted. However, since the movement of the movable contact 13 is restricted by the lifting portion 42a formed on the internal mover 2, the movement is opposite to that of the second embodiment.

In each of the above embodiments, the shape of the movable contact 13 has been described as being substantially mountain-shaped; however, the shape is not limited to this, and any shape may be used as long as it can be separated from the fixed contact by a lifting part. If the configuration is as shown in the fourth embodiment shown in FIGS. 12 and 13, it can be used for a device with a large electric capacity. This is a modification of the second embodiment. The difference from the second embodiment is that a substantially U-shaped movable contact 44 and a compression spring 4 are provided in two holes 28c formed on the lower surface of the internal mover 28.
5 are loosely fitted into each other, and both ends of the lifting portion 29b of the external movable member 29 are formed in a sloped shape, and the other structures are the same. Further, each of the above embodiments has been described as a two-way pulse switch, but if the movable contacts 13 and 44 are respectively modified, it becomes a one-way pulse switch. That is, in the first to third embodiments, only half of the substantially mountain-shaped movable contact 13 is used, and in the fourth embodiment, only one of the two movable contacts 44 is used. It turns out.

As described in detail above, according to the configuration of the present invention, the internal movers 11, 28, 42 engaged with the operating members consisting of the rotating body 12 and the operating shaft 30 in each embodiment
and a guide portion that is longer than the length of the internal mover 11, 28, 42 by a predetermined distance, that is, a notch portion 14d.
The internal mover 1 is placed in the internal spaces 29a and 43a.
1, 28, 42 are fitted loosely into the external movers 14, 2.
It will be configured in combination with 9 and 43.

The present invention has the above-mentioned configuration and operation, and has the following effects.

That is, the internal movable member engaged with the operating member and the guide portion that is longer than the length of the internal movable member by a predetermined interval,
A movable contact is provided on one of the external movable element into which the internal movable element is loosely fitted, and a movable contact is provided on one of the two movable elements, and a lifting portion for regulating the operation of the movable contact is formed on the other. By shifting the movement timings of the movable elements, the lifting portion can regulate the switching operation of the movable contact, and it is possible to provide a small-sized pulse switch with a simple configuration and a stable switching operation state.
