As shown in figs. 1 and 2, comprise supporting shell 10 according to the essential structure of slide switch SSW of the present invention, supporting shell comprises that mainly formation roughly is the inwall 10a of inverted U-shaped (cross section) inner space 10b.By the upper wall 10c sealing of supporting shell, upper wall 10c engages with the top of wall 10a space 10b in the top.On the other hand, space 10b seals by base plate 10d in its lower end, and by being screwed to the screw 10e on the boss 10b that links to each other with vertical a pair of inwall 10a respect to one another, base plate 10d is connected securely.Supporting shell 10 (comprising inwall 10a) is preferably made by the electric plastic material of going up insulation.
The slide mass 12 (also being made by plastic material) of insulation movably is installed among the inner space 10b of insulation supporter shell 10, so that can reciprocatingly slide between a plurality of service positions.In this respect, slide mass 12 comprises by elongated open 10g from supporting shell 10 outwardly directed button 12a (as clearlying show that among Fig. 2).Elongated open 10g forms on the upper wall 10c of supporting shell 10.Button 12a can be moved by manual or automated manner, thereby also causes slide mass 12 to move (promptly moving along the direction shown in the arrow among Fig. 2 14) along straight line in the 10b of the inner space of supporting shell 10.
The elasticity movable contact of being made by electric conducting material (for example metal) 16 operationally is installed among the inner chamber 12b that 12 li of slide masses limit.Movable contact 16 is formed processing (for example by bending process), so that form the contact part 16a that protrudes in the place that is located substantially on the middle part, the profile of the contact part 16a of Tu Chuing is roughly V-shaped in an illustrated embodiment.Be that movable contact 16 is carried out bending process to the important point of the present invention in addition, so that form a pair of side elastic part 16b respect to one another, the outside bow of this opposite side elastic part 16b a little outwards opens each other.Adopt in such a way, when movable contact 16 is inserted among the chamber 12b of slide mass 12, side elastic part 16b will apply biasing force facing to the relative wall 12c of slide mass, thereby by friction movable contact 16 " lock " therein.
A plurality of narrow bar shaped fixed conductors 18 have relative end portion, and these end portions are placed among slit 20a and the 20b, and these slits be respectively that of supporting shell 10 to horizontal madial wall 10a respect to one another on and form on the base plate 10d.Fixed conductor 18 all is installed in the side, that is to say, for slide mass 12 slip of (with contact part 16b); The plane of each bar all is a traverse, and is parallel with the plane of other conductor 18.Therefore, simply by along straight line mobile button 12 in elongated space 10g, so that slide mass 12 is slided in the 10b of the inner space of supporting shell 10, that just can make the movable contact 16 that driven by slide mass 12 and selection contacts fixed conductor 18.
Therefore as shown in accompanying drawing 3, when slide mass 12 is mobile in the 10b of the inner space of supporting shell 10 (for example moving) along the direction shown in the arrow A among Fig. 3, the elastic characteristic of movable contact 16 will cause contact part 16a edge upwards to enter the direction displacement of the inner chamber 12b of slide mass 12, thereby be pressed on the fixed conductor 18.Show a kind of like this state with solid line among Fig. 3.The intrinsic elasticity of reed conductor 16 will promote contact part 16a again towards the outside direction displacement of the chamber 12b of slide relative body 12 then, as among Fig. 3 with shown in the imaginary projection line, enter and following a pair of adjacent fixed conductor 18 state of contact.
As shown in Figure 4, the end that preferred scheme is a conductor 18 stretches out from supporting shell 10, thereby a kind of means are provided, and makes slide switch to carry out work with external circuit and is connected.Therefore, slide switch of the present invention can be configured to carry out work with external circuit and is connected.Moving of slide mass 12 just will cause circuit to be switched on or to be disconnected (contact part 16a cross-over connection a pair of fixed conductor) promptly thus, like this.
Assembly work according to slide switch SSW of the present invention shown in Fig. 1 to 4 is quite simple.About this point, at first movable contact 16 is inserted among the chamber 12b of 12 li formation of slide mass, its relative each side elastic part 16b (terminal end that bends to upright mode by movable contact 16 constitutes) is pressed on the respective wall 12c of the chamber 12b that forms slide mass 12.Be noted that about this point curved sides elastic part 16b is in order to form a kind of spring, thereby the wall 12c of the slide mass 12 that forms chamber 12b is applied outside elastic force.Therefore, when among the chamber 12b that movable contact 16 is inserted slide masses 12, the position that side elastic part 16b will make movable contact 16 by temporary transient " lock " therein, thereby the mistake that movable contact may be shifted out is reduced to minimum level.
Under quilt " lock " situation in slide mass 12 chamber 12b of the position of movable contact 16, then can insert whole slide mass parts among the inner space 10b of supporting shell 10.Can insert its corresponding slit to fixing strip conductor 18 among 20a and the 20b then.By end 10d being fixed on the inwall 10a, can finish the assembly work of whole slide switch SSW with screw 10e.As mentioned above, this slide switch SSW that assembles just can carry out work by fixed conductor 18 and circuit and be connected, so that response button 12a mobile (thereby the contact part 16a's of response movable contact 16 is mobile) reaches the required switch control to these circuit.
To describe other embodiment and improvement project of the present invention below.Wherein the parts of same structure indicate with identical Reference numeral number.In addition, those will be not described further referring to figs. 1 through 4 structures that illustrated in the above.The slide switch SSW shown in Fig. 5 for example

1In used elongated tubular member be used as fixed conductor 18 '.
In accompanying drawing 6 to 7, illustrated according to another slide switch SSW of the present invention
2Embodiment.As can be seen from the figure, slide switch SSW
2Fixedly touch article 22 with plane of bending, this fixedly touch article 22 mainly comprise the protuberance 22a of protuberance, the contact surface 16a position of the protrusion on the protuberance 22a of these protuberances and the movable contact 16 is relative.And when laying fixed conductor 22, make the plane of each conductor 22 parallel with the moving direction of slide mass 12.In addition, these strip conductors 22 are placed and are positioned among the recess 20a ' and 20b ' of corresponding size and shape, and these recesses are to form on to laterally relative wall 10a and base plate 10d at that of supporting shell 10.
Therefore, according to the slide switch SSW shown in Fig. 6 and Fig. 7
2Embodiment, when the slip of response slide mass 12, when contact part 16a moved through the summit of protuberance 22a, movable contact 16 will be bent upwards towards the chamber 12b of slide mass 12.The elastic force of movable contact 16 is increased, and the elastic force of this increase will attempt more to force contact part 16a to return its " normally " state.When contact part 16a moved through protuberance 22a, by clearly " card is taken " sound action, contact part 16a was inserted in adjacent protuberance fiercely between the 22a like this.As shown in Figure 7, contact part 16a just contacts with two this adjacent protuberance 22a, so that be switched on or switched off required external circuit.
Another embodiment of slide switch SSW has been shown in accompanying drawing 8-9.As can be seen from the figure, the SSW of slide switch shown in Fig. 8 to 9
3Basically with the slide switch SSW above-mentioned according to Fig. 6 to 7
2Identical, but its most important difference is that movable contact 26 roughly is hexagon.More particularly, be used for slide switch SSW
3In movable contact 26 comprise the contact surface 26a and the side spring flanging 26b of a pair of big V-arrangement, in addition as can be seen, side elasticity flanging 26b comprises aduncate terminal area 26c, makes each terminal area 26c all draw close towards another terminal area.
Side elasticity flanging 26b is bow or somewhat outside deflection a little preferably, with box lunch among the chamber 12b of movable contact 26 insertion slide masses 12 time (in the embodiment shown in Fig. 8 to 9, chamber 12b is formed by the vertical end wall 12c ' of the each interval of more close arrangement), each side elasticity flanging 26b is with inside elastic deflection, cause outwards applying biasing force, thereby impel conductive reed 26 " lock " therein by friction facing to the wall 12c ' of slide mass 12.
In addition, side elasticity flanging 26b can have vertical orientated slit 26d, vertical orientated slit 26d side elasticity flanging 26b and contact part 26d with and the joint of relevant terminal elongated area 26c between extend so that increase above-mentioned elastic force.On the other hand, the outside deflection of upper terminal elongated area 26a, so that make its end (referring to Fig. 9, can finish up with the zone of downward and inside crimping in its end) bear against on the upper wall of sliding part 12, thereby impel to whole movable contact 26 produce deflections and elasticity (for example increase the biasing force of movable contact 26, and this biasing force attempt to make movable contact towards with fixing electric conductor 22 on the contacted direction of protuberance 22b move).
The other shape of the movable contact 26 that can be used for the SSW3 of slide switch shown in Fig. 8 to 9 has been shown in Figure 10 A and 10B.More particularly, as shown in Figure 10 A, end extension 26c ' can comprise the fork-shaped termination 26e that forms open slot 26e ', and this open slot 26e ' is used to hold the outward extending tongue-shaped member 26f from another extension, end 26a.In addition, tongue-shaped member 26f can have the horizontal wide part 26g of head, prevents that tongue-shaped member 26f and slit 26e ' from separating so that assist.In the embodiment shown in Figure 10 B, extension, end 26c " has relative interlocking C shape notched region 26h.Therefore in each embodiment shown in Figure 10 A and the 10B, terminal extension 26c will draw close and exceed (promptly intersecting) each other, so that form a pair of flexible tail shaped portion branch, further improves the characteristic of conductive reed as spring.
Slide switch WSSW shown in Figure 11 and Figure 12
4Basically with the slide switch SSW above-mentioned according to Fig. 8 to Fig. 9
3Embodiment is identical, and its difference has been further to improve the shape of the movable contact 26 that uses.About this point, movable contact 36 shown in Figure 11 to 12 is basic identical with the movable contact 26 shown in Fig. 8 to Fig. 9, movable contact 36 has contact part 36a and opposed side edges spring flanging to 36b, and they are structurally with all the contact part 26a with above-mentioned is identical with side spring flanging 26b on the function.
Yet for the side elasticity flanging 36b of the movable contact 36 of embodiment shown in Figure 11 to 12, each all finishes up with top spring section 36c.That is to say that each upper springs part 36c comprises respectively inwardly and bandy section 36d and 36e, and with these sections of such order configuration, so that form the relative a pair of recess that roughly takes the shape of the letter U from the cross section.These upper springs parts 36c just is used for increasing the elasticity of movable contact conductive reed 36 of the chamber 12b of slide mass 12, and this elasticity attempts to force contact part 36a to contact with the protuberance 22a of fixed conductor 22.
Yet the upper end of sidewall 36b might not need to make U-shaped.Can from Figure 13 A, find out about this point, inwardly can constitute the V-arrangement cross section respectively with bandy regional 36d and 36e.As shown in Figure 13 B, outwardly-bent regional 36e itself can finish up with terminal flanging 36f up in addition.
Fixed conductor can be made various shape.Therefore.Though do not have shown in the drawings, for example the embodiment shown in Fig. 6 to 7,8 to 9 and 11 to 12 just can use the tubular conductor 18 shown in the fillet conductor 18 shown in Fig. 1 to 2 and/or Fig. 5 '.That is to say that the shape of fixed conductor can be that elongate strip (for example with identical according to the above-mentioned fixed contact 18 of Fig. 1 to 2) and/or its shape of being kept upright can be tubular (for example shown in Fig. 5).
Should be able to be clear that now, adopt the employed conductive reed of slide switch of the present invention can produce several advantages.For example because adopt the movable contact made according to any one the foregoing description all will on the position movable contact " lock " in the chamber that forms by slide mass, so the movable contact of chance appearance and other switch block mistake separated from one another will be reduced to minimum level in assembling.Therefore, the easier employing automatic technology of slide switch of the present invention (for example Robotics) is assembled.
It is most important and preferred embodiment that above combination is considered at present; describe the present invention; yet should be understood that; the present invention is not limited to disclosed embodiment; but on the contrary, the present invention is the protection range that claim limited that will cover various improvement included in the present invention's design and equivalent structure and submit to this specification.
