Description

[Detailed description of the invention] [Field of application of the invention] This invention relates to a switch device that presses a slide member and uses the reversing action of a spring to perform contact/separation operations between a fixed contact and a movable contact. This invention relates to a switch device that can be flattened without being extended in the longitudinal direction.

[Background of the idea]

Switch devices that connect and release contacts in conjunction with the pressing operation of a slide member, and which utilize the reversing action of a spring, usually have a slide member directly engaged with a movable conductor plate equipped with a movable contact. It was driving. As an example of this, there is a device disclosed in Japanese Utility Model Publication No. 10033/1983, as shown in FIG. That is, in this conventional example, as shown in the figure, rigid individual terminals 2 and 3 having contact portions are arranged facing each other at a constant interval on the bottom surface of a box-shaped case 1 whose top surface is open, and one side 4a is the individual terminal. A key-shaped rigid common terminal extending horizontally above 2 and 3 is connected to the other side 4.
It is fixed to the case 1 via b. Further, the lower end has a contact part that comes into contact with and separates from the contact part of the individual terminals 2 and 3, and has two spring pieces 5a and 5b extending from the lower end and the upper end to the center part, and has a rigid hollow part. The movable switching plate 5 is rotatably locked by inserting one side 4a of the common terminal 4 into the hollow part thereof and sandwiching it between the two spring pieces 5a and 5b at a point P in the center of the one side 4a. death,
and electrically connected. The upper end of the movable switching plate 5 is engaged with a hole 6a formed in the hollow part of a sliding body 6 that slides in the horizontal direction, and the frame 7 is folded to make the sliding body 6 slidable. The bent pieces 7a are caulked to the protruding parts 1a on both sides of the case 1, and a coil spring 8 is attached to the operating part 6b protruding from the sliding body 6 via a spring stopper 9.

In the switch device configured as described above, the sliding body 6 is directly engaged with the movable switching plate 5, and by operating this sliding body 6, the individual terminals are , 3 and the contact portion of the movable switching plate 5 are brought into contact and separated.
That is, the movable switching plate 5 and the sliding body 6 are arranged at a substantially right angle, and the movable switching plate 5 is operated in a direction substantially parallel to the sliding direction. Therefore, in such a configuration, the dimension of the movable switching plate 5 in the installation direction, in other words, the dimension in the height (thickness) direction in the figure becomes large, and it is difficult to meet the demands for downsizing and flattening the switch device. I couldn't do it.

In view of the above points, there is a method of installing the movable switching plate 5 and the sliding body 6 in parallel to promote downsizing and flattening. However, when the movable switching plate 5 and the sliding body 6 are made parallel, the movable switching plate 5
Since the structure is such that the movable switching plate 5 is switched by engaging a part of the sliding body 6 on both sides (mostly the end on the anti-contact side), it is possible to flatten the sliding body 6. There was a problem in that the end of the tube protruded and the longitudinal dimension became large, making it difficult to downsize (shorten in the longitudinal direction).

Therefore, until now, a switch device in which the sliding body 6 and the movable switching plate 5 are arranged substantially parallel and the movable switching plate 5 is displaced in a direction substantially perpendicular to the sliding body 6 to perform switching has not been seen.

[Purpose of invention]

This invention was made in view of the problems of the prior art described above, and its purpose is to provide a switch device that can be made flat and compact at the same time.

[Summary of the idea]

In order to achieve the above object, this invention includes a case that holds at least two terminals, a slide member that slides along the case and switches the terminals held by the case by moving them toward and away from each other during the sliding process; A fixed terminal as one terminal of the two terminals having a contact on the fixed side in a switch device equipped with elastic biasing means for always elastically biasing the sliding member in a direction to push the sliding member from the back side to the front side of the case. , a center terminal as the other terminal having a support plate locking protrusion and a leaf spring locking protrusion, and a central terminal that faces the contact of the fixed side contact and is capable of contacting and separating from the fixed side contact. a contact point on the movable side located on one end side, a contact portion located on the other end side that can be pressed against the case by the pressing protrusion of the slide member, and at least a protrusion for locking the support plate of the central terminal. and an opening into which the plate spring locking protrusion is loosely inserted, an opening into which the plate spring locking protrusion is loosely inserted, and a main body is loosely inserted into the opening of the conductor plate. , when installed, one end of the support plate is provided with a locking portion that locks on the edge of the opening of the conductor plate near the contact point on the movable side, and the other end of the support plate locks with the support plate locking protrusion; It is locked to the leaf spring locking projection of the center terminal, and the other end is locked to the edge of the opening of the conductor plate on the side opposite to the leaf spring locking projection with the support plate locking projection in between. , the contact portion side of the conductor plate is elastically biased in a direction away from the fixed side contact while the conductor plate is stretched between the support plate and the plate spring return protrusion of the slide member. The leaf spring, which is pushed back when the slide member moves back, contacts the opposite side of the contact on the movable side of the conductor plate in the OFF state, and when the contact is pressed from a state where they are separated from each other, the contact portion is pressed. The contact drive mechanism consisting of the leaf spring, conductor plate, and support plate is reversed beyond the dead center where the leaf spring is compressed to the maximum according to its forward movement, and the movable side contact becomes the fixed side contact. After coming into contact with and turning on, it is held at approximately this drive end position, and by further pressing from this holding position, the holding state is released, and the elastic biasing means returns it to the initial state direction. In the return movement process, the leaf spring return protrusion comes into contact with a part of the leaf spring, pushes the leaf spring back, compresses the leaf spring to the maximum extent, crosses the dead center again, and reverses the contact drive mechanism to move. the sliding member which separates the contact on the side from the contact on the fixed side and turns it off; and when the sliding member is pressed from the off state to turn it on, the holding state at the holding position is maintained and the on state is set. cam means for releasing the holding state of the front part and allowing the sliding member to return to the OFF state by the elastic biasing means and maintaining the OFF state when the sliding member is pressed. The feature is that the sliding member is provided with a protrusion for restoring the leaf spring, and by returning the leaf spring, the rear end of the conductor plate (assuming the operating part of the sliding member is on the front side) does not have to be extended and remains flat. It is intended that the conductor plate be able to return to the OFF direction in response to the backward movement of the slide member.

The plate spring return protrusion 17i is disposed on the outside, and the conductor plate pressing protrusion 17h is disposed on the inside. Further, a recess 17l is formed on the lower surface to which a compression spring 17k can be attached.

The case 11 is made of an insulating synthetic resin material and is integrally molded into a box shape with openings on the upper surface and the front end side, and has the sliding groove 11a on the upper edge and the tongue pin 17b on the front end side. A tamping pin receiver 11b that can be fitted at one end, and this tamping pin receiver 11

When assembling the above elements into the case 11, as shown in FIG.
The connecting end 12b of the fixed terminal 12 and the connecting end 13a of the central terminal 13 are respectively inserted into 1e, and both are planted adjacent to the lower surface of the case 11.

Further, the support plate 15 is attached to the opening 14b of the conductor plate 14 from above. This is the support plate 15
Insert the locking groove 15c into the locking edge 14c on the contact 14a side of the conductor plate 14, and then insert the locking groove 15c on the other end side.
The locking groove 14g at the upper end of the side edge 14h of the conductor plate 14
This is done by placing it on the Next, the engagement hole 16d of the leaf spring 16 is inserted into the contact portion 14 of the conductor plate 14.
The plate spring 16 is inserted into and engaged with the engagement protrusion 14f protruding from the inner edge of the opening 14b on the d side.
In the figure, bend the arm in the direction of arrow C, and
A locking protrusion 1 protruding from the upper end of the side edge 14h of the
The locking protrusion 16e of the plate spring 16 is locked to the end surface of the plate spring 4i on the contact portion 14d side. In this way,
The conductor plate 14, the support plate 15, and the leaf spring 16 can be integrated. At this time, the leaf spring 16
is the engagement protrusion 14f of the conductor plate 14 and the engagement protrusion 1
4i are locked in a state in which they are springed outward in the figure, so unless the plate spring 16 is artificially pressed to release the locked state, the three parties will not dismantle this. The three can be treated as one block 19.

Then, these 19 blocks are attached to the central terminal 13. In this case, first, the locking portion 15a of the support plate 15 protruding toward the lower surface side in FIG. As shown in FIG. 3, the plate springs are locked from diagonally above, and the opening 15b of the support plate 15 is inserted into the leaf spring locking protrusion 13c. Then, as shown in FIG. 2, the locking portion 16a of the leaf spring 16 that is locked to the locked portion 14i comes into contact with the inclined surface 13h of the leaf spring locking projection 13c. When the leaf spring 16 is pushed in the direction of arrow D from this position, the protrusion 16a is bent in the direction of arrow E along the slope 13h, and as shown in FIG. It fits into the V-groove 13f through the convex portion 13i, and becomes stable at the deepest position of the V-groove 13f. At this time, as shown in FIG. 5, since an outward elastic force (in the direction of arrow F) acts on the leaf spring 16,
An upward force G is applied to the conductive plate 14 as a whole in the figure. However, since the protrusion 15d of the support plate 15 is locked in the locking groove 14g of the conductor plate 14, the support plate 15 is rotated counterclockwise in the figure with the locking portion 15a locked in the V-groove 13e as the center. moment occurs. As a result, a force in the direction of arrow H acts on the locking groove 15c side of the support plate 15. Therefore, with this configuration, the force that urges the contact portion 14d side of the conductor plate 14 in the direction of arrow G is applied to the support plate 15.
The protrusion 15d of the support plate 15 suppresses the force downward in the figure, and the locking groove 15c of the support plate 15 suppresses the force that urges the contact 14a side of the conductor plate 14 in the direction of the arrow H (downward). As shown in FIG. 5, the case 11 is in an equilibrium state in a slightly inclined state with respect to the lower surface thereof. Then, from above,
Compression spring 17 that biases the slide 17 in the direction of the arrow
k is attached to a predetermined position in the recess 17l on the lower surface of the slide 17, and the slide 17 is attached to the case 11. After that, one end of the tamper pin 17b is inserted into the tamper pin receiver 11b through the elongated hole 17c, the other end is loosely fitted into the cam groove 17d, the tamper pin retainer 17j is attached to the receiver groove 11c, and then the frame is inserted from above. 1
8 is attached to the case 11, and the switch device is assembled.

The switch device assembled as above is
As shown in FIG. 6, it is slightly pressed down by the lower surface of the slide 17 and is regulated to a position substantially parallel to the lower surface of the case 11. Therefore, in this state, an upward force is acting on the contact 14a side of the conductor plate 14 in the figure, and the contact of the fixed terminal 12 and the contact 14a of the conductor plate 14 are separated from each other.

From this state, when the operating portion 17e at the front end of the slide 17 is pushed in the direction of arrow B, the conductor plate pressing protrusion 17h located inside the operating protrusion 17f on the rear end side of the slide 17 moves into contact with the conductor plate 14. 14d, and rotates the conductive plate 14 in the clockwise direction in the figure around the contact point between the tip of the conductive plate 14 and the lower surface of the slide 17. Then, the contact portion 1 of the conductor plate 14
4d is displaced downward and reaches the reversal point of the leaf spring 16 (the dead center position where it is compressed to the maximum), the conductor plate 14 moves by itself, and the contact 14a of the conductor plate 14 comes into contact with the contact 12a of the fixed terminal 12. When connected, a lock state occurs and the circuit is turned on. At this time, the conductor plate 14
is held between the contact 12a of the fixed terminal 12 and the conductor plate pressing projection 17g (FIG. 7).
Further, the slide 17 is also brought into a locked state by the action of the tamper pin 17b that engages with the cam groove 17d.

That is, when the slide 17 is pressed, the conductor plate pressing protrusion 17h of the slide 17 presses the contact portion 14d of the conductor plate 14 in response to the reciprocating movement, and the contact portion 14d side is pushed against the case 11 with the contact point as the center.
Rotate it to the bottom side. In this process, the support plate 15 rotates counterclockwise in FIG. Since the conductor plate 14 is located at a high position relative to the lower surface and the upper limit of the conductor plate 14 is regulated by the contact point on the lower surface of the slide 17, as the conductor plate 14 is pushed down, the conductor plate 14 moves toward the slide 17. The locking groove 15c moves slightly along the lower surface of the case 11 toward the operating portion 17e until it crosses the line connecting the V-groove 13e and the contact portion. At this time, the leaf spring 16 is compressed, and when it almost passes the line (dead center position), the leaf spring 16 expands, and the conductor plate 14 is reversed and runs by itself. This allows the contact 14 on the movable side to
a comes into contact with the fixed side contact 12a, resulting in a locked state. FIG. 10 shows the state in the vicinity of passing through the dead center during this contact-on operation.

From this state, when the slide 17 is further pushed in the direction of arrow B, the second stage conductor plate is pressed which is outside the conductor plate pressing protrusion 17h and protrudes further downward, as shown in FIG. The protrusion 17g presses the contact portion 14d, causing the conductor plate 14 to contact the contact 1.
4a, the end J on the right side (on the contact portion 14d side) can be rotated clockwise in the drawing using the end J on the right side (on the side of the contact portion 14d) as a fulcrum, and a full stroke state as shown in FIG. 8 can be achieved. In this way, when the conductor plate 14 is brought into a full stroke state, the end K on the left side (the operating section 17e side of the slide 17) in the drawing of the contact 14a can be forcibly peeled off from the contact 12a of the fixed terminal 12. . In this full stroke state, the contact portion 14d side of the conductor plate 14 is in contact with the receiving portion 13d of the center terminal 13, and the protrusion 1 of the leaf spring 16 is in contact with the receiving portion 13d of the center terminal 13.
The end of 6b enters into relief groove 13g, and is designed so as not to obstruct the forced peeling operation. This forced peeling operation is performed by removing the welded contacts 12
This is to separate the parts 14a and 14a, and this is done by rotating the conductive plate 14 clockwise in the drawing using the end J as a fulcrum as described above. this is,
This has been made possible by configuring the rear end of the slide 17 in two stages. That is, the second-stage conductor plate pressing protrusion 17g, which is not involved in driving the conductor plate 14 in the ON direction, is provided on the slide 17, and after locking,
Since the pressing force applied to the slide 17 can be amplified and transmitted to the contact point 14a by the lever principle, the welded portion can be reliably peeled off with extremely small force.

The forcible peeling is carried out using the play stroke of the slide 17 when locked, and when the slide 17 is pushed to this play stroke (approximately 1 to 1.5 mm in this embodiment), the cam groove 17d and the tongue pin 17b are separated. The locked state is released and the slide 17 returns in the direction of arrow A by the action of the compression spring 17k. In this return process, the plate spring return protrusion 17i of the operating protrusion 17f comes into contact with the protrusion 16c of the plate spring 16 from the position shown in FIG. 7, and returns it in the direction of arrow C. Then, in order to pull back the leaf spring 16 in the direction C until the slide 17 returns to the OFF position, the conductor plate 14 also moves from the position shown in FIG. point) and returns to the position shown in FIG. 6, and as a result of this return, the contacts 12a and 14a are separated and return to the OFF state.

That is, as described above, when the contacts are separated from the contact state, the leaf spring 16 moves toward the slide 1.
During the return movement of step 7, the plate spring return protrusion 17i returns the conductor plate 14, and accordingly the conductor plate 14 moves counterclockwise around the contact portion of the movable contact 12a with the fixed contact 14a. Rotate to . In this process, the conductor plate 14 moves in the direction of the operating part 17e of the slide 17, and when the plate spring 16 is compressed and passes the point where the plate spring is compressed to the maximum (dead point), the plate spring 16 expands and the contact 12a side The contacts move away from each other as they move toward the slide side.
Turns off. FIG. 11 shows the state in the vicinity of passing through the dead center during this contact-off operation.

Therefore, even without providing a means for returning the conductor plate 14 to the rear end side of the conductor plate 14, by returning the leaf spring 16, the conductor plate 14 linked thereto can be returned to the off position. Therefore, the dimensions on the rear end side can be kept small. At this time, since the structure for returning the leaf spring 16 is within the thickness of the conductor plate pressing protrusions 17g and 17h that drive the conductor plate 14 in the on direction, flattening of the switch device is not hindered.

In the above embodiment, the conductor plate 14, the support plate 15, and the leaf spring 16 are integrated as one block, and the central terminal 1 implanted in the lower surface of the case 11
3 is shown, but before installing the center terminal 13 in the case 11, the three-piece block 19 is attached to the center terminal 13 in advance, and the conductor plate 14, support plate 15, It is also possible to integrate the leaf spring 16 and the central terminal 13 into one block. In this case, the plate spring 16 is attached to the V of the plate spring locking projection 13c.
The leaf spring 16 is engaged with the groove 13f and the engagement protrusion 14f of the conductor plate 14, and is in the state shown in FIG.
Since the elastic force of and each member maintain equilibrium,
Unless the leaf spring 16 is artificially bent to release the engagement, the four parts are integrated and can be handled as one block.

Further, the above embodiment has a structure that can be made into blocks in consideration of ease of assembly, but for example, the engaging protrusion of the conductive plate 14 and the engaging hole 16d of the leaf spring 16 are omitted, and the conductive plate 14 and Even if the switch device is simply locked with the leaf spring 16 at the relevant portion, the operation will be the same, and the effect of flattening and miniaturization can be achieved. Furthermore, the locking protrusion 14i of the conductor plate 14 and the locking protrusion 16e of the leaf spring 16 that can be locked thereto are also designed with ease of assembly in mind, and the same effects can be achieved even without both. be able to.

[Claims for Utility Model Registration] A case that holds at least two terminals, a slide member that slides along the case and operates a switch by moving the terminals held in the case closer to or away from each other during the sliding process, and a slide member that operates at all times. A switch device comprising an elastic biasing means for elastically biasing the case in a direction from the back side to the front side, comprising: a fixed terminal as one terminal of the two terminals having a fixed side contact; and a support plate. a central terminal as the other terminal provided with a locking protrusion and a plate spring locking protrusion; and a central terminal that faces the fixed side contact, is capable of coming into contact with and separating from the fixed side contact, and is located on one end side. a contact point on the movable side, and a contact portion located on the other end side that can be pressed against the case side by contacting the pressing protrusion of the slide member;
a conductor plate having an opening into which at least a support plate locking projection and a leaf spring locking projection of the center terminal are loosely inserted; an opening into which the leaf spring locking projection can be loosely inserted;
The main body is loosely inserted into the opening of the conductor plate, and when installed, one end is engaged with the edge of the opening of the conductor plate near the contact point on the movable side, and the other end is engaged with the support plate engagement protrusion. a support plate having a stop portion, one end of which is locked to the leaf spring locking protrusion of the center terminal, and the other end of which is locked to the opposite leaf spring locking portion of the opening of the conductor plate with the support plate locking protrusion in between; It is locked to the end edge of the stop protrusion side, and while the conductor plate is stretched between it and the support plate, the abutment side of the conductor plate is elastically biased in the direction away from the contact on the fixed side. , the leaf spring pushed back by the leaf spring return protrusion of the slide member when the slide member moves back, and the contact on the movable side of the conductor plate abutting on the side opposite to the arrangement surface in the off state, and the contacts are separated from each other. When the pressing operation is performed from the state, the contact portion is pressed, and the contact drive mechanism consisting of the leaf spring, conductor plate, and support plate is moved beyond the dead point where the leaf spring is compressed to the maximum according to its forward movement. After the contact on the movable side comes into contact with the contact on the fixed side and turns on, it is held at approximately this drive end position, and by further pressing from this holding position, the holding state is released, and the It is returned to the initial state direction by the elastic biasing means, and in the return movement process, the leaf spring return protrusion comes into contact with a part of the leaf spring and pushes the leaf spring back, compressing the leaf spring to the maximum and causing it to die again. reversing the contact drive mechanism beyond the point to separate the movable contact from the fixed contact;
A slide member to be turned off; when the slide member is pressed from the off state to turn it on, the held state is maintained at the holding position; and when the slide member is pressed from the on state, the held state is changed to the held state. A switch device comprising: cam means for releasing the slide member to allow the return operation of the slide member by the elastic biasing means to turn the slide member into an off state, and maintaining the off state.
