Description

Switch
The present invention relates to the switch that rotary manipulation or bulldozing operation by operating body carry out the break-make change action, particularly anti-on printed base plate the time floated structure the switch soldering.Also relate to the switch that torsion-coil spring is also used as travelling contact, above-mentioned torsion-coil spring is used to make operating body to reset to initial position.
Existing a kind of switch is opened as described in flat 6-86240 number as the Japanese Utility Model communique is real, and by the synthetic resin system self-box of upper end open, the rotatable earth's axis is propped up action bars on this self-box, this action bars applied the torsion-coil spring formation of spinning reduction power.In this switch, setting common fixed contact and switching at the inner bottom surface of self-box and use fixed contact, two fixed contacts are bent into the right angle, respectively as outside terminal to the derivation of self-box below.
In addition, torsion-coil spring is as travelling contact, and its 1st and the 2nd wrist stretches out from the coiling portion two ends that are rolled into some circles.The 1st wrist shape that is in line extends, and contacts always with shared fixed contact.The 2nd wrist is bent into the U font, can connect vis-a-vis liftoff with switching with fixed contact.
The switch of this structure is that each outside terminal soldering is used under the state on the printed base plate circuit.During use, when action bars is in non-operating state, the 2nd wrist of torsion-coil spring is positioned at about vertical direction and leaves the initial position that switches with the fixed contact surface, and switch is keeping dissengaged positions.Rotation is during action bars under this state, and this wrist is operated the bar pushing and contact with switching with the fixed contact surface, and common fixed contact and switching are passed through the torsion-coil spring conducting with fixed contact, so switch switches to on-state from dissengaged positions.In addition, cancelled pushing force to action bars after, action bars and torsion-coil spring are got back to initial position again under the elastic force effect of torsion-coil spring, the 2nd wrist of torsion-coil spring leaves to switch uses fixed contact, switch is switched into dissengaged positions once more.
But in the above-mentioned existing switch, owing to be provided with common fixed contact and switching fixed contact at the inner bottom surface of self-box, the outside terminal of these fixed contacts must be derived from the self-box below.Therefore, adopt so-called face installation method switch be installed on the printed base plate, when the plate face of each outside terminal being soldered to the bonding land on printed base plate surface with soldering etc., because the soldering position only concentrates on a side of self-box, so, the problem that switch floats at opposite side produced.
If derive to the bending process of each outside terminal execution complexity and with its not coplanar from self-box, these outside terminals are floated with the terminal soldering on printed base plate as anti-, though can address the above problem, but, if make the switch miniaturization, then each outside terminal being implemented three-dimensional bending process and it is stretched out has big difficulty technically.Especially table side and inboard two-way ground selector switch towards installation the time, must be in the confined space of self-box, common fixed contact and switching are carried out complicated configuration with fixed contact, and therefore, the miniaturization of this switch is impossible actually.
In addition, in the above-mentioned existing switch, common fixed contact must be set and switch at the inner bottom surface of pole plate and use fixed contact, as if making the switch miniaturization, can not guarantee the insulating properties between two fixed contacts, and be subjected to big restriction to the configuration the outside terminal from two fixed contacts.The 2nd wrist to press with the contact of fixed contact be shape decision by the 2nd wrist for switching, so, must carry out complicated bending machining to torsion-coil spring, also cause the processing cost raising of torsion-coil spring.
The Japanese Utility Model communique is real to be opened clear 61-112535 number, real opening and has disclosed another this type of switch of example for flat 4-36733 number, and this switch is to adopt intermediate plate shape fixed contact as the push switch that switches with fixed contact.In this switch, if set switch highly with the pressure of the spring between a pair of intermediate plate of fixed contact, though can guarantee the contact a when wrist of torsion-coil spring embeds between two intermediate plates presses, but, making the clip sheet produce enough springs presses, be difficult in processing, therefore, still be not easy to realize miniaturization.
The present invention makes in view of the above problems, and its purpose is to provide a kind of switch, and the self-box of the formation shell of this switch is made of the 1st pole plate and the 2nd pole plate.But the 1st pole plate is derived the 1st terminal of soldering from synthetic resin system base station; The 2nd pole plate is stacked on the 1st pole plate and is integral with it, but derives the 2nd terminal of soldering from synthetic resin system base station.Several terminal branches are located on 2 pole plates of mutual so stacked all-in-one-piece, can derive several terminals simply,, just can prevent the come-up of switch the bonding land of these terminal solderings to printed base plate from any direction of self-box.In addition, because that the outer surface separately of the 1st and the 2nd pole plate is synthesized resin base mounted is topped, so when installing on printed base plate, the conducting parts that exposes externally is few, can improve packing density.
In the switch of the present invention, a wrist of torsion-coil spring always with the fixed contact Elastic Contact, another wrist can with contact chip connect from, like this, make torsion-coil spring have function as travelling contact, simultaneously, be located at these fixed contacts and contact chip branch stacked mutually and all-in-one-piece pole plate and covering.In this structure, the counter-force when making the contact chip that covers a side be crimped on the pole plate one side group platform has been guaranteed the contact pressure of contact chip with the torsion-coil spring wrist.So, can carry out the shaping processing of contact chip simply.And, because this contact chip is located at and pole plate covering of homonymy not, so, increased substantially the configuration degree of freedom of fixed contact and contact chip, can make contact chip, torsion-coil spring miniaturization, make the switch miniaturization.
Switch of the present invention has self-box, travelling contact and operating body; Self-box has common fixed contact and switches uses fixed contact; Travelling contact have the 1st contact portion that contacts with shared fixed contact always and with switch with contact can connect from the 2nd contact portion; Operating body make the 2nd contact portion with switch with fixed contact connect from; It is characterized in that, above-mentioned self-box is made of the 1st pole plate and the 2nd pole plate, the 1st pole plate is from the 1st terminal of synthetic resin system base station derivation energy soldering, and the 2nd pole plate is stacked on the 1st pole plate and is integral with it, but derives the 2nd terminal of soldering from synthetic resin system base station.
The structure of travelling contact is not limit, and all can so long as can be operated the body driver.If the torsion-coil spring that applies recuperability to operating body is also used as travelling contact, then can make the part generalization, help the miniaturization of switch.
In addition, the aforesaid operations body can be the pressing type operation body of push operation, also can be the rod-type operating body of rotary manipulation.Which kind of pattern no matter is if make operating body stretch out to foreign side from the composition surface of the 1st and the 2nd pole plate, when being installed to switch on the printed base plate, because operating body is outstanding along the printed base plate surface, so can under any state in the table switch be installed.
The structure of above-mentioned the 2nd pole plate is not limit, and the person all can so long as have the contact chip.Also can be in aggregates with metal plate shape.If the 2nd pole plate that adopts is metallic plate and the synthetic resin system of the stretching out in base station with contact chip, then since the outer surface separately of the 1st pole plate and the 2nd pole plate to be synthesized resin base mounted topped, it is few to be exposed to outside conducting parts, so, the packing density in the time of can improving the switch soldering to printed base plate.
Above-mentioned the 1st terminal and the 2nd terminal all have the function of floating terminal as anti-.It also can be the virtual terminal that does not have electrical relation with fixed contact.When the 1st terminal is the outside terminal of common fixed contact, the 2nd terminal is when switching the outside terminal of using fixed contact, be located on 2 pole plates with the fixed contact branch owing to can and switch, so also help the miniaturization of switch from this point these common fixed contact.
Switch of the present invention has the 1st pole plate, the 2nd pole plate, torsion-coil spring and operating body.The fixed contact of the 1st pole plate is provided on the synthetic resin system base station.The 2nd plate plate and the 1st pole plate are stacked and form one, have the contact chip with the crimping of base station inner face.Torsion-coil spring is provided in the inside of the 1st pole plate and the 2nd pole plate, have always with the 1st wrist of fixed contact Elastic Contact and can with above-mentioned contact chip connect from the 2nd wrist.The 2nd wrist Elastic Contact of operating body and torsion-coil spring is slided this wrist between contact chip and base station inner face.
The aforesaid operations body can be the pressing type operation body of push operation, also can be the rod-type operating body of rotary manipulation, and no matter which kind of pattern all must apply recuperability by the 2nd wrist of torsion-coil spring.
The shape of above-mentioned contact chip is not limit, as long as form the cantilever beam shape, when especially the free end of the contact chip of making the U font being crimped onto the base station inner face, the spring span of contact chip is very long, can reduce all shapes.
Form the face that slips that the 2nd wrist with torsion-coil spring slips at the free end of contact chip, if making this slip facial end tilts towards the direction of leaving the base station inner face, then when switch connection, the 2nd wrist of torsion-coil spring successfully can be imported between the slip face and base station inner face of contact chip.
Establish rib in that the base station inner face is prominent, the 2nd wrist of torsion-coil spring is connected on this rib, in the break-make change action of switch, because the 2nd wrist slides, so both resistances to sliding are little, can make the displacement successfully of the 2nd wrist on rib.
The present invention has following effect.
Because self-box is to be made of mutual stacked all-in-one-piece the 1st pole plate and the 2nd pole plate, and a plurality of terminals branch of energy soldering is located on these 2 pole plates, so, can derive plurality of terminals simply from any direction of self-box, by each terminal soldering in the bonding land on printed base plate surface, can prevent the come-up of switch.And, because the outer surface separately of the 1st and the 2nd pole plate is topped by synthetic resin system base station, so when installing on printed base plate, it is few to expose outside conducting parts, can improve packing density.
Be also used as travelling contact owing to apply the torsion-coil spring of recuperability to operating body, so, realize the generalization of part, help the miniaturization of switch.
Owing to operating body is stretched out to foreign side from the composition surface of the 1st and the 2nd pole plate,, can switch be installed on printed base plate with any state in the table so when switch was installed, operating body stretched out along the printed base plate surface.
In addition, since the outside terminal of the 1st terminal as common fixed contact, the outside terminal of the 2nd terminal as switching usefulness fixed contact, so, can be located at these common fixed contact and switching on 2 pole plates with the fixed contact branch, help the miniaturization of switch.
Since a wrist of torsion-coil spring always with the fixed contact Elastic Contact, another wrist and contact chip can connect from, make torsion-coil spring have function as travelling contact, so, when being located at these fixed contacts and contact chip branch on mutual stacked all-in-one-piece the 1st pole plate and the 2nd pole plate, even the simple shape of contact chip and torsion-coil spring can guarantee that also contact between the two presses, and the configuration degree of freedom of increase fixed contact and contact chip, can make the switch miniaturization.
In addition, contact chip 17 is made the U font, when its free end was crimped on the base station inner face of the 1st pole plate, the spring span of contact chip was long, and whole shape is dwindled.
Owing to form the slip face that the 2nd wrist with torsion-coil spring slips at the free end of contact chip, the facial end of this slip is tilted towards the direction of the base station inner face that leaves the 1st pole plate, when switch connection, can successfully import the 2nd wrist of torsion-coil spring between the slip face and base station inner face of contact chip.
Establish rib owing to dashing forward at the base station inner face of the 1st pole plate, the 2nd wrist of torsion-coil spring is connected on this rib, so in the break-make change action of switch, the 2nd wrist slides on rib, both resistances to sliding are little, can make the displacement successfully of the 2nd wrist.

The switch of present embodiment is made of action bars 3 on the 1st pole plate of the 1st and the 2nd pole plate 1,2, the rotatable earth's axis, torsion-coil spring 4 from the rotation recuperability to this action bars 3 that apply.The 1st pole plate and the 2nd pole plate are mutually stacked and be integral and form self-box.
The 1st pole plate 1 has by the integrally formed base station 5 of insulating properties synthetic resin, is adorning outwardly directed fixed contact 6 on base station 5.Fixed contact 6 disposes obliquely along the medial surface of base station 5, and its surface is gone up and formed teat 6a.This fixed contact 6 stretches out to foreign side from 3 sides of base station 5 as each outside terminal 6b, 6c, 6d respectively along the inner bottom surface configuration of base station 5, and each outside terminal 6b, 6c, 6d keep idiostatic.
Base station 5 is box-shapeds of opening above, forms otch 7 on the one side, forms the anti-projection 5a that floats on the another side relative with otch 7.Form copulational protuberance 5b on all the other two sides adjacent with this side.At the upright step-like fulcrum of establishing with large-diameter portion 8a and minor diameter 8b 8 of the inner bottom surface of base station 5, guide wall 9 and location division 10 surround the large-diameter portion 8a of this fulcrum 8.Guide wall 9 is more outstanding upward than location division 10, forms cannelure 11 by this guide wall 9 and location division 10 around fulcrum 8.Also forming section on the inner bottom surface of base station 5 is hemispheric rib 12, and it is the circular arc at center that this rib 12 is with fulcrum 8.
The 2nd pole plate 2 has by the integrally formed base station 13 of synthetic resin, is adorning outwardly directed conductive metal plate 14 on the base station 13.Base station 13 forms the tabular of open end, topped the 1st pole plate top.Edge part at metallic plate 14 forms several elastic engagement piece 15 and an outside terminal 16, and each elastic engagement piece 15 bends downwards from the relative two sides of base station 13, and outside terminal 16 bends to oblique below from the another side of base station 13.Form the contact chip 17 that bends at metallic plate 14, this contact chip 17 stretches out to oblique below from the inside of base station 13.As Fig. 6~shown in Figure 8, contact chip 17 is configured as the U font, and its front end (free end) forms to the outstanding slip face 18 in side.Facial 18 the end of sliding forms bent sheet 18a, this bent sheet 18a (see figure 8) that tilts upward.
The open end, top of the 2nd pole plate 2 topped the 1st pole plates 1, the 2nd pole plate 2 and the 1st pole plate 1 are stacked to one by each elastic engagement piece 15 mutually with the clamping of copulational protuberance 5b.At this state, the inner bottom surface of the facial 18 crimping base stations 5 of the slip of contact chip 17, by its counter-force make contact chip 17 from Fig. 6 solid line position towards the displacement of double dot dash line position.Each outside terminal 6b, 6c, 6d and each front end of the outside terminal 16 of deriving from the 2nd pole plate 2 of deriving from the 1st pole plate 1 become with one side approximately with the bottom surface of base station 5.
Action bars 3 is integrally formed by synthetic resin, the thin rhabodoid 20 that has thick cycle body 19 and stretch out to the side from this cycle body 19.Wearing hole 20a on the rhabodoid 20, when the minor diameter 8b that hole 20a is enclosed within fulcrum 8 goes up, on just rotatable earth's axis Zhi Zaidi 1 pole plate 1 of action bars 3.At this state, an end of cycle body 19 is outstanding upward from the otch 7 of the 1st pole plate 1, and the abutting part 19a that is formed on the other end is positioned at the inside of the 1st plate plate 1.
Torsion-coil spring 4 has the function as travelling contact, has the 4a of coiling portion that is rolled into some circles and linearly the 1st and the 2nd wrist 4b, the 4c that stretches out from the two ends of the 4a of this coiling portion.The 4a of coiling portion is inserted in the groove 11 of the 1st pole plate, and its profile is directed to wall 9 and location division 10 is spacing.The 1st wrist 4b passes the top and fixed contact 6 Elastic Contact of location division 10, by its front end and joining of teat 6a and can not above-below direction limited movably.The 2nd wrist 4c is by guide wall 9 restriction opening angles, by the inner bottom surface and rib 12 butts of base station 5.The abutting part 19a Elastic Contact of the front end of the 2nd wrist 4c and action bars 3 applies the rotation recuperability by its counter-force to action bars 3.
When the switch of the above-mentioned structure of assembling, earlier the 4a of coiling portion of torsion-coil spring 4 is inserted in the groove 11 of the 1st pole plate 1, the root of the 2nd wrist 4c is engaged with guide wall 9.Like this, even the shape of torsion-coil spring has some deviations, as shown in Figure 9, the open angle of the 1st wrist 4b and the 2nd wrist 4c also is restricted to certain angle [alpha].Then, the hole 20a of action bars 3 is enclosed within on the minor diameter 8a of fulcrum 8, and with front end and the abutting part 19a butt of the 2nd wrist 4c of torsion-coil spring 4.Like this, because action bars 3 is applied in counterclockwise rotation recuperability among Fig. 9, so, heading on the medial surface of base station 5 above the rhabodoid 20, stretch out upward from otch 7 on the top of the cycle body 19 of action bars 3.Then, the open end, top of the 2nd pole plate 2 topped the 1st pole plates 1, the re-spective engagement projection 5b clamping of each elastic engagement piece 15 of the 2nd pole plate 2 and the 1st pole plate 1, the 1st pole plate 1 and the 2nd pole plate 2 just are stacked to one, are assembled into switch shown in Figure 1.
The switch that is assembled into such an order, as shown in figure 13, the 1st pole plate 1 is positioned on the printed base plate 21 with state down, and each outside terminal 6b, 6c, 6d, 16 front end are welded in the bonding land (figure does not show) on printed base plate 21 surfaces with soldering 22, and the switch quilt cover is installed on the printed base plate 21.At this moment, each outside terminal 6b, the 6c that derives from the 1st pole plate 1,6d except 3 directions of cycle body 19 projected directions of action bars 3 by soldering, the outside terminal 16 of deriving from the 2nd pole plate 2 at the opposition side of cycle body 19 projected directions of action bars 3 by soldering, so, can prevent the come-up of switch conscientiously.And, form the anti-projection 5a that floats in a side of base station 5, should anti-float projection 5a extends at the rightabout of the projected direction of cycle body 19, should anti-float projection 5a and pass between outside terminal 6d and the outside terminal 16 surperficial butt with printed base plate 21, so, even put forward the power of action bars 3 on having in effect on the switch, each outside terminal 6b, 6c, 6d, 16 soldering part also are not easy to come off.
During use, when the not operation of action bars 3, be positioned at initial position shown in Figure 10, at this state, though the 1st wrist 4b and fixed contact 6 Elastic Contact of torsion-coil spring 4, but because the 2nd wrist 4c is positioned at the position of the slip face 18 that leaves contact chip 17, so switch is keeping dissengaged positions.If the cycle body 19 with action bars 3 under this state pushes towards Figure 13 arrow A or B direction, then action bars 3 is center clockwise direction rotation with the minor diameter 8b of fulcrum 8, the front end that makes the 2nd wrist 4c is to equidirectional displacement, as shown in figure 11, the middle body of the 2nd wrist 4c contacts with the slip facial 18 of contact chip 17, fixed contact 6 and contact chip 17 become conducting state by torsion-coil spring 4, and promptly switch switches to on-state.At this moment, as shown in Figure 8 because bent sheet 18a tilts upward with respect to base station 5 inner bottom surfaces, so, can be effectively the 2nd wrist 4c guiding slide facial 18 below.Further the cycle body 19 of action bars 3 when equidirectional the pushing, as shown in figure 12, the 2nd wrist 4c slides the on-state of maintained switch below facial 18 and between the inner bottom surface of base station 5 sliding.After the pushing force of having cancelled action bars 3, the 2nd wrist 4c of torsion-coil spring 4 is reset into original posture by the elastic force of itself, action bars 3 also is pushed gets back to initial position shown in Figure 10, thereupon, the 2nd wrist 4c leaves the slip face 18 of contact chip 17, and switch is switched into dissengaged positions.
In the above-described embodiments, because a name outside terminal 6b, 6c, 6d, be located in 16 minutes on mutual stacked all-in-one-piece the 1st pole plate 1 and the 2nd pole plate 2, so, can derive several outside terminals 6b, 6c, 6d, 16 from any direction of self-box simply, these outside terminals 6b, 6c, 6d, 16 solderings bonding land, can prevent the come-up of switch conscientiously to printed base plate 21 surfaces.In addition, because the outer surface separately of the 1st and the 2nd pole plate 1,2 is topped by synthetic resin system base station 5,13, so when installing on printed base plate 12, the conducting parts that exposes the outside is few, can improve packing density.
In the foregoing description, fixed contact 6 as common fixed contact is located on the 1st pole plate 1, be located on the 2nd pole plate 2 as the contact chip 17 that switches with fixed contact, when the 1st pole plate 1 and the 2nd pole plate 2 are stacked to one, the inner bottom surface crimping of slip of contact chip 17 facial 18 and base station 5, so, as long as contact chip is made simple U font, just can guarantee the pressure that contacts between the 2nd wrist 4c of contact chip 17 and torsion-coil spring 4.Therefore, not only the processing of this contact chip 17 and torsion-coil spring 4 is simple, and can make this contact chip 17 and torsion-coil spring 4 miniaturizations.In addition, because fixed contact 6 and contact chip be located on the 1st pole plate 1 and the 2nd pole plate 2 in 17 minutes, so, increased the configuration degree of freedom of fixed contact 6 and contact chip 17, as mentioned above, can make contact chip 17 and torsion-coil spring 4 miniaturizations, thereby can make the switch miniaturization.
Because forming, the free end of contact chip 17 slides facial 18, end in this slip facial 18 forms towards leaving the bent sheet 18a that base station 5 inner bottom surface directions tilt, so, when the connection of switch, can successfully import the 2nd wrist 4c of torsion-coil spring 4 between the inner bottom surface of slide face 18 and base station 5.
In addition, in the break-make change action of switch,,, can make the 2nd wrist 4c displacement successfully on the rib 12 that is based in base station 5 inner bottom surfaces by action bars 3 so the resistance to sliding between the 2nd wrist 4c and the rib 12 is little because the 2nd wrist 4c of torsion-coil spring 4 slides.
Figure 14 is an installment state stereogram of representing the variation of above-mentioned switch.Figure 15 is the exploded perspective view of this switch, annotates with same numeral with part corresponding among Fig. 1~Fig. 3, and its explanation is omitted.
As shown in figure 15, the switch of this variation, except the shaping form and the quantity of outside terminal was different with above-mentioned switch, the 1st pole plate 1 was all identical with the essential structure of the 2nd pole plate 2, action bars 3, torsion-coil spring 4 etc.That is, 1 outside terminal 6e of formation and fixed contact 6 conductings on the 1st pole plate, this outside terminal 6e from the bottom surface bending obliquely upward of base station 5 with stretching out.3 outside terminal 16a, 16b, the 16c of formation and contact chip 17 conductings on the 2nd pole plate, these outside terminals 16a, 16b, 16c stretch out to foreign side from 3 sides of base station 13, and the outer surface of its front end and base station 13 is on same one side.Among these outside terminals 6e, 16a, 16b, the 16c, as long as the shape of change outside terminal 6d shown in Figure 4 can obtain the outside terminal 6e of the 1st pole plate 1, in this case, the cut-out of the root of other outside terminal 6b, 6c is removed, also as long as the off-position of change metallic plate 14 shown in Figure 5 and each outside terminal 16a, 16b, the 16c that shape can obtain the 2nd pole plate 2 needn't make metal die again.
The order assembling same of this switch with Fig. 1~switch shown in Figure 3, but the state that is inverted in the table of self-box is used.That is, as shown in figure 14, the 2nd pole plate 2 is placed on the printed base plate 21 down, by the front end of each outside terminal 6e, 16a, 16b, 16c is welded in the bonding land on printed base plate 21 surfaces with soldering 22, switch is installed on the printed base plate 21 with regard to quilt cover.At this moment, the outside terminal 6e that derives from the 1st pole plate 1 is by the opposition side of soldering at cycle body 19 projected directions of action bars 3, outside terminal 16a, the 16b that derives from the 2nd pole plate 2,16c by soldering in 3 directions except cycle body 19 projected directions of action bars 3, so, can prevent the switch come-up conscientiously.In use, when the direction of the arrow B of Figure 14 or C pushed, then action bars 3 was middle mind-set counter rotation with fulcrum 8 the cycle body 19 of action bars 3, with above-mentioned switch similarly, carry out the break-make change action.
In the foregoing description,, just can be installed on the printed base plate 21, so can provide versatility high switch with the arbitrary state in the table as long as each outside terminal is done some changes.
