Description
The present invention relates to a kind of seesaw switch that is used as the power change switch of electric equipment or electronic equipments.
Fig. 5 represents a kind of by the clear 57-4134 of Japanese Utility Model patent gazette number disclosed universal interaction change over switch.Wherein, operating parts 20 has a pressing means 22 that is contained in its top, and this operating parts 20 can be along the direction shown in the arrow x-y among the figure, by predetermined amount, around bolster 21 swings.Along with the swing of operating parts 20, an actuator 24 that is contained in compression spring 23 promotions in the operating parts 20 can swing around bolster 21.Finish pushing of conductive plate 25 that central termination 26 is being supported again by the motion that swings of the actuator 24 that promoting of compression spring 23.As a result, make conductive plate 25, the mobile contact 27a, the 27b that are installed in conductive plate 25 two ends are correspondingly joined with fixed contact 30a, 30b or separate around the swing of the top ends of central termination 26.A flat spring 31 that roughly is " M " font is being set on the top surface of conductive plate 25.When above-mentioned mobile contact 27a and 27b contacted with corresponding fixed contact 30a and 30b, flat spring 31 can make to impact and alleviate.When swinging, actuator 24 slides along the surface of flat spring 31.Symbol 28 and 29 is represented the termination of stretching out from fixed contact 30a and 30b respectively.
In the seesaw switch of this structure, when operating personnel push pressing means 22 an end, and make operating parts 20 thus around bolster 21, when x or y direction are rotated, mobile contact 27a or 27b just join with corresponding fixed contact 30a or 30b, thereby make central termination 26 and the fixed contact 30a or the 30b that are provided with dividually with central termination 26, be electrically connected mutually by conductive plate 25.When a mobile head contact with corresponding fixed contact, be in the free end generation strain that is subjected to the flat spring 31 that actuator 24 pushes, the motive force of spring 23 is compressed in absorption thus.So, alleviated can mobile contact and the impact that takes place when joining of fixed contact, so just can prevent in operating process, owing to impact the vibration (a kind of conductive plate 25 on swinging mounting point, beat and with the phenomenon of central termination 26 disengagements) of the conductive plate 25 cause.
In the known universal interaction change over switch of another kind, a compression spring is being set between the swinging mounting point of operating parts and conductive plate, it is installed into " L " shape bending basically, at an end of operating personnel's pressing operation face and when making operating parts rotate scheduled volume thus, it is bent to opposite shape.That is to say that in the seesaw switch of this structure, when being arranged on compression spring on the swinging mounting point of conductive plate and having an end to curve because of the rotation of operating parts, conductive plate is just promoted by this compression spring that curves and along the direction swing that curves.
In the universal interaction change over switch of said structure, flat spring 13 is contained on the conductive plate 25, to alleviate in the impact in when operation and the vibration of conductive plate 25, yet this impact and vibration can take place when operating personnel push an end of pressing means 22 with strength and are added to a bigger operating physical force on the operating parts 20 unavoidably, therefore, when above-mentioned mobile contact joined with corresponding fixed contact, conductive plate 25 can be thrown off because of impact and central termination 26, also can produce electric arc thus.The arc heating that is produced can be damaged conductive plate 25 or central termination 26 again, thereby shortens its useful life.These bring difficulty for again the resistance of increase capacity or impulse current.Owing to will drive conductive plate 25 compression spring 23 and actuator 24 these two parts must be set again, thereby the part number is increased, bring many troubles for thus its assembly work by the rotation of operating parts 20.
In above-mentioned back a kind of general seesaw switch, the compression spring becomes " L " shape substantially between operating parts and conductive plate, because compression spring handle conductive plate is pushed its swinging mounting point to, thereby just is not easy to produce vibration.Yet, because swinging operation is to utilize the bending force of compression spring to form, thus operating physical force a little less than, make operating personnel that a desired certain operating structure of power switch that can satisfy electric equipment or electronic equipments can not be arranged.In addition, it also is very difficult that the compression spring is assembled into bending, and this makes difficulty of assembling processing.
The present invention makes for the problem that solves above-mentioned universal interaction change over switch existence, its objective is provides a kind of seesaw switch, it has a conductive plate that is difficult for vibration, is arranged long useful life, can guarantee desired operating physical force and have good assembling processability.
The seesaw switch of the present invention of making in order to achieve the above object contains a central termination and fixed contact of configuration with being separated from each other; Conductive plate with the energy mobile contact that can join with the said fixing contact and separate, above-mentioned conductive plate can swingingly be supported by central termination; The operating parts that can swingingly support, it has one because of carrying out the operating surface that above-mentioned swinging operation is swung; The helical spring that reverses that is arranged between aforesaid operations spare and the conductive plate.The above-mentioned helical spring that reverses has a winding part that joins with aforesaid operations spare elasticity and a pair of arm that protrudes from above-mentioned winding part two ends, they and above-mentioned conductive plate be positioned at 2 of swinging mounting point both sides respectively elasticity join; Above-mentioned conductive plate has a space that can allow the winding part that is pressed into by aforesaid operations spare to move therein.
Seesaw switch with said structure has the arm 7b that a pair of one-tenth case of bending ground and conductive plate 5 elasticity are joined owing to reverse helical spring 7.Reversing the winding part 7a that helical spring 7 is installed into it joins with operating parts 8 elasticity; When operating parts 8 was pushed winding part 7a from the top, winding part 7a moved in the 5b of the space of conductive plate 5 and the amount of bow of arm 7b is changed.Thereby when the end of operating personnel's pressing operation face 8a also makes operating parts 8 rotate thus, reverse helical spring 7 and be pressed into earlier among the 6a of space, reverse helical spring then and promptly rotate, and conductive plate 5 is rotated.The result can make conductive plate 5 swing around swinging mounting point A along with the swing of operating parts 8.Again because this that reverses helical spring to arm be with conductive plate be positioned at 2 of swinging mounting point both sides respectively elasticity join, so can obtain enough big contact pressure by the elastic force that the swinging mounting of conductive plate is put the arm of a side, and conductive plate is pushed to the swinging mounting point by the elastic force that is positioned at the arm on the conductive plate opposite side, prevent vibration thus.

Below, with reference to Fig. 1～Fig. 4 embodiments of the invention are described.Fig. 1 represents the on-state of the embodiment of seesaw switch of the present invention, Fig. 2 represents the dissengaged positions of this embodiment, Fig. 3 is the exploded perspective view of this embodiment, and Fig. 4 is the top view of the major part of this embodiment, represents one the conductive plate that reverses helical spring is housed.
In these figure, have the central termination 2 of supporting convex 2a and have fixed contact 3 fixedly termination 4, be arranged on the bottom of the shell of making the box shape with being separated from each other.At an end of conductive plate 5 the mobile contact 6 that an energy and fixed contact 3 are connected and separate is being set, conductive plate 5 is swingingly to be bearing on the central termination 2 around the swinging mounting point A as a contact between supporting convex 2a and the conductive plate 5.This conductive plate 5, on its lower-most edge of middle body a recess 5a is arranged, above-mentioned supporting convex 2a just is inserted in this recess 5a; Conductive plate 5 also has plug-in mounting to reverse space 5b and the groove 5c and the 5d of helical spring 7 usefulness; Be used for preventing to reverse the anti-skidding flake 5e of helical spring 7 slippages; Two bridle joint spare 5f, wherein each can both with the driving projection 8b bridle joint and the disengagement mutually of operating parts 8.Reverse helical spring 7 and be configured on the conductive plate 5, its winding part 7a is inserted in the space 5b of conductive plate 5, prevent that by above-mentioned anti-skidding flake 5e it is by slippage; Its a pair of arm 7b that protrudes from the two ends of winding part 7a is inserted in respectively groove 5c and the 5d.From above when installing to the winding part 7a that reverses helical spring 7 on the conductive plate 5 with being pressed into space 5b, arm 7b is bent, so helical spring 7 is loaded onto with moving down.
Almost can be bearing in the aforesaid operations spare 8 of the upper opening 1a of shell 1 sealing rotationally on the shell 1 around bolster 9.Operating surface 8a since operating parts 8 around the rotational of bolster 9 and alternatively swing.Operating parts 8 is provided with on its inner wall surface and drives protruding 8b, and driving protruding 8b can be meshed with the bridle joint spare 5f of conductive plate 5 or throw off.When operating parts 8 was rotated because of mutual swinging operation, each drove protruding 8b and all meshes with bridle joint spare 5f, to rotate conductive plate 5; And with the Plane intersects fork of the swinging mounting point A of rotary centerline that contains operating parts 8 and conductive plate 5.By Fig. 1 and Fig. 2 as seen, when operating parts 8 when bolster 9 rotates, drive protruding 8b and make conductive plate 5 along rotating with the direction of operating parts 8 direction of rotation.Simultaneously, the winding part 7a that reverses helical spring 7 that is arranged between operating parts 8 and the conductive plate 5 is flexibly contacted with the middle body of the lower surface of operating parts 8, and two point elasticities that are positioned at swinging mounting point A both sides of a pair of arm 7b that makes it and conductive plate 5 contact.
In the seesaw switch of this configuration structure, because reversing helical spring 7 has a pair of arm 7b that is case of bending and conductive plate 5 Elastic Contact, and be bent at this arm 7b and will reverse helical spring 7 under the state and be mounted to its winding part 7a and the middle body Elastic Contact of operating parts 8 lower surface, thereby when winding part 7a be subjected to operating parts 8 from top come push the time, winding part 7a moves in the space 5b of conductive plate 5 by the amount of bow that changes arm 7b.Promptly, when the end of pressing operation face 8a and when operating parts 8 is rotated thus, the winding part 7a that reverses helical spring 7 at first is forced among the 5b of space, reversing helical spring 7 then promptly rotates, also makes thus conductive plate 5 to rotate, the result, because the swing of operating parts 8 makes conductive plate 5 put the A swing around swinging mounting.
Like this, when operating personnel as shown in figure, for example push operating surface 8a shown in Figure 2 the left part, and when operating parts 8 counter-clockwise direction are rotated, make the height of the winding part 7a that reverses helical spring 7 continue to descend, become zero up to the gradient of operating parts 8.7a is in extreme lower position when winding part, and promptly when the amount of bow of arm 7b was maximum, operating personnel's finger can be felt powerful reaction.Along with the further pressing operation face of operating personnel 8a, winding part 7a begins to rise, and promptly clockwise direction rotates then, and conductive plate 5 clockwise directions are rotated.At this moment, above-mentioned mobile contact 6 is just correspondingly with on fixed contact 3 contact as illustrated in fig. 1, makes the central termination 2 that is separated from each other setting and fixed contact 3 pass through conductive plate 5 thus and is electrically connected, thereby convert on-state to.When operating personnel push the right part of the operating surface 8a of state shown in Figure 1, and when operating parts 8 is deasil rotated, with operation same as described above basically, after operating personnel's doigte arrives stronger reaction, winding part 7a is rapid immediately to rotate counter-clockwisely, and conductive plate 5 is rotated counter-clockwisely.Thus, above-mentioned mobile contact 6 and fixed contact 3 are separated, thereby convert the state of cut-out to.
In this embodiment, because being 2 points that are positioned at swinging mounting point A both sides (the darkest point of groove 5c and 5d) with conductive plate 5, a pair of arm 7b that reverses helical spring 7 flexibly joins, thereby can mobile contact 6 firmly is pressed on the fixed contact 3, and obtain converting to the desired big contact pressure of on-state thus by the elastic force of an arm 7b of conductive plate 5 one sides; And by the elastic force effect of another arm 7b of conductive plate 5 opposite sides, conductive plate 5 is pushed to swinging mounting point A securely, prevent the vibration of the conductive plate 5 that the impact when contacting with fixed contact 3 because of above-mentioned mobile contact 6 causes thus.So can provide one to have long useful life, high reliability and be suitable for the raising capacity and the seesaw switch of impulse current resistance.Again owing to only need reverse helical spring 7 in this seesaw switch, between operating parts 8 and conductive plate 5, and this reverses helical spring 7 and can easily be installed on the conductive plate 5 again, thereby can reduce the part number that will use, can improve and assemble processing characteristics.Also the elastic force that is produced because of the arm 7b that reverses helical spring 7 is delivered to operating parts 8 unchangeably as operating physical force, so just easy setting operation power.For example, if use a helical spring 7 that big operating physical force is provided with arm 7b of big elastic force, the structure that operating personnel just can have a sure power transfer that satisfies electric equipment or electronic equipments to require.
In addition, in the present embodiment owing to carry out conversion operations during rotating operation spare 8, each drive protruding 8b all with bridle joint spare 5f engagement, rotating conductive plate 5, this rotation is and is identical by reversing the direction that helical spring 7 rotates conductive plate 5.Simultaneously, owing to be to be configured to drive protruding 8b pitch with the Plane intersects of the swinging mounting point A of rotary centerline that contains operating parts 8 and conductive plate 5, thereby conductive plate 5 actuating force that can directly add by operating parts 8 and swinging.In other words, if being configured to conductive plate 5 just drives by reversing helical spring 7, and it is because arc heating for example that mobile contact 6 and fixed contact 3 adhere to mutually, and then operating personnel are used for the power of pressing operation spare 8 and will be absorbed by the bending of arm 7b, can not be applied on the conductive plate 5.In contrast, in the present embodiment, conductive plate 5 is to drive simultaneously by reversing helical spring 7 and driving protruding 8b, even above-mentioned mobile contact 6 and fixed contact 3 adhere to mutually, the power of operating personnel's pressing operation spare 8 still can become big actuating force and be applied on the conductive plate 5 by driving protruding 8b.Two contacts 3 and 6 that adhere to are separated from each other, seesaw switch is returned to reset condition.
Although the structure of the seesaw switch of the foregoing description is with the single fixed contact that can join or separate with central termination, can be susceptible to the present invention thus and can also make with two fixed contacts, join with central termination selectively or separate.
By above-mentioned explanation as seen, because a pair of arm that reverses helical spring is and two points of the both sides of the swinging mounting point of conductive plate Elastic Contact respectively, thereby just can get enough big contact pressure by the elastic force at an arm of a side of swinging mounting point of conductive plate; And conductive plate is pushed to the swinging mounting point by the elastic force effect at another arm of conductive plate opposite side, can prevent to produce vibration thus.So can provide one to have long useful life and be suitable for the raising capacity and the seesaw switch of impulse current resistance.Again owing between the operating parts of this seesaw switch and conductive plate, only need reverse helical spring, thereby can reduce the part number, can improve to assemble and add interaction performance.The operating physical force of switch also is directly transferred to operating parts, so just can easily be set because reverse the elastic force of helical spring.
