Abstract

In a process of producing a keyboard switch, a continuous track (10) of a metal foil is machined into two metallic terminal components (13, 14) constituting links between two carrier strips (11, 12). A base housing component (22) is cast from a high temperature resistant material around the terminals (13, 14) and is connected to the carrier strips (11, 12) through two tags (29) protruding outwards from opposite, outer side surfaces (27) of the base housing component (22). In an inner recess (23) of the base housing component (22) a domed metal disc (31) having an acoustically damping coating (32) on the convex side surface thereof, an elastically compressible rubber component (33) and a push button (37) are arranged. On top of the base housing component (22), a top housing component (30) preferably made from the same high temperature resistant plastics material is arranged. Within the recess (23) of the base housing component (22), the terminal (13, 14) define electric contacts (19, 20) with which the domed metal disc (31) co-operates. The terminals (13, 14) are separated from the carrier strips (11, 12) and bent into the configuration of pins of an electronic keyboard switch, and the keyboard switch is still connected through the tags (29) to the carrier strips (11, 12) transferred to a test stand (5), in which the keyboard switch is tested. Provided the keyboard switch is identified as a properly functioning keyboard switch, the tags (29) are separated from the base housing component (22).

Ved tilvejebringelsen af 5 to bærebånd og to flige, der er støbt til et respektivt bærebånd, understøttes tryktastomkobleren mekanisk stabilt i sin fastgørelse til de to bærebånd, når tryktastomkobleren føres frem gennem de ovenfor angivne trin.said carrying straps, the metallic components being arranged with their outer terminal ends integrally connected to the supporting straps via said outer terminal ends, further casting two tabs in the above step c) to a respective supporting strap. By providing two carriers and two tabs molded to a respective carrier, the pressure key switch is mechanically stable in its attachment to the two carriers as the push key switch is advanced through the above steps.

En yderligere forøgelse af den mekaniske fiksering og understøtning 10 af tryktastomkobleren når denne føres frem gennem de ovenfor angivne trin, opnås i overensstemmelse med et alternativ til den ovenfor angivne foretrukne udførelsesform for fremgangsmåden ifølge den foreliggende opfindelse ved, at hver metallisk terminalkomponent udgør en forbindelse mellem de to bærebånd, og ved, at hver af de 15 nævnte metalliske komponenter har to ydre terminaler, der afgrænser ydre terminalender, som er integreret forbundet til et respektivt bærebånd.A further enhancement of the mechanical fixation and support of the pressure key coupler as it advances through the above steps is achieved in accordance with an alternative to the above preferred embodiment of the method of the present invention in that each metallic terminal component forms a connection between the two carriers and know that each of the said metallic components has two outer terminals defining outer terminal ends integrally connected to a respective carrier.

I overensstemmelse med den foretrukne udførelsesform for fremgangsmåden ifølge den foreliggende opfindelse er omkoblingselementet en 20 hvælvet metalskive som under trin d) anbringes med sin kuppel eller hvælving ragende udefter fra udsparingen, og som i sin normalt hvælvede form er i den nævnte første tilstand og kan deformeres fra denne hvælvede form til en nedbøjet form udgørende den nævnte anden tilstand, og at taporganet, der under trin f) anbringes i åbningen i 25 tophuskomponenten virker på metalskiven på en sådan måde, at taporganet ved aktivering deformerer den hvælvede metalskive fra den hvælvede form til en nedbøjet form.In accordance with the preferred embodiment of the method of the present invention, the switching element is a 20 vaulted metal disk which, in step d), is mounted with its dome or vault protruding outwardly of the recess and which in its normally vaulted form is in said first state and can be deformed from this vaulted shape to a bent shape constituting said second state, and that, during step f), the tap member is placed in the aperture of the top housing component acting on the metal disk in such a way that, upon actuation, the tap member deforms the vaulted metal disk from the vaulted mold to a bent form.

Under trin f) anbringes der fortrinsvis et elastisk, sammentrykkeligt legeme mellem taporganet og metalskiven, idet det elastisk sammen-30 trykkelige legeme, således som det vil blive forklaret nedenfor, tjener flere formål, nemlig at forøge metalskivens bevægelse eller slaglængde, når denne deformeres, og eventuelt beskytte metalskiven ved forsegling langs skivens periferiske kant og følgelig beskytte metalskiven og de elektriske kontaktorganer mod korroderende gasser 35 og udsættelse for høje temperaturer under en overflademonteringspro- 4During step f), an elastic compressible body is preferably arranged between the tab member and the metal disc, the elastic compressible body, as will be explained below, serves several purposes, namely to increase the movement or stroke of the metal disc as it deforms. and optionally protecting the metal disk by sealing along the peripheral edge of the disk, and consequently protecting the metal disk and electrical contacts against corrosive gases 35 and exposure to high temperatures during a surface mounting process.

En hvælvet metalskive frembringer et ubehageligt og skarpt klik, når den deformeres. I overensstemmelse med et specielt aspekt af den fo-5 religgende opfindelse er det blevet erkendt, at dette klik kan dæmpes, hvilket resulterer i en mere behagelig lyd ved tilvejebringelse af en akustisk dæmpende materialecoating på den ene sideflade af den hvælvede metalskive, hvilken sideflade udgør den ydre eller konvekse sideflade af den hvælvede metalskive.A vaulted metal disk produces an unpleasant and sharp click when deformed. In accordance with a particular aspect of the present invention, it has been recognized that this click can be attenuated, resulting in a more comfortable sound by providing an acoustically damping material coating on one side face of the vaulted metal sheet, which side face constitutes the outer or convex lateral surface of the vaulted metal disk.

10 En fremgangsmåde af den indledningsvis angivne art kendes fra det europæiske patentskrift nr. 0.030.473. I overensstemmelse med denne i kendte fremgangsmåde fremstilles en tryktastomkobler af flere enkelt dele, der hver frembringes i overensstemmelse med den ovenfor angivne fremgangsmåde. Den færdige tryktastomkoblers bundhusdel, tophusdel, 15 omkoblingselement og taporgan eller som defineret i ovennævnte europæiske patentskrift omkoblingselement-drivorgan, frembringes individuelt understøttet af hvert sit bærebåndsæt, der efter færdiggørelse af de fire enkeltkomponenter føres sammen og anbringes i korrekt position eller registrering styret af føringshuller, der er udformet i 20 bærebåndene ud for de enkelte komponenter. Med den fra ovennævnte europæiske patentskrift kendte fremgangsmåde skal der til fremstilling af en tryktastomkobler udføres i alt fire separate fremgangstrin af den indledningsvis omhandlede art til fremstilling af fire delkomponenter af den færdige tryktastomkobler. Som man umiddelbart vil 25 forstå, er den fra ovennævnte europæiske patentskrift kendte fremgangsmåde for det første meget materialekrævende, da der til fremstilling af hver af tryktastomkoblerens fire enkeltkomponenter skal benyttes et metalbånd, af hvilket der i overensstemmelse med den ovenfor omhandlede fremgangsmåde fremstilles bærebånd, og for det 30 andet meget kompliceret, da de fire separate metalbærebånd med hver sin enkeltkomponent skal føres nøjagtigt sammen under det afsluttende samlingstrin, ved hvilket bundhuskomponenten, omkoblingselementet, taporganet og tophuskomponenten samles.A method of the kind mentioned in the introduction is known from European Patent Specification No. 0.030.473. According to this in the known method, a pressure key coupler is made of several single parts, each produced in accordance with the above method. The bottom housing part, top housing part, top housing part, switching element and tap member, or as defined in the aforementioned European patent switching element driver, are individually supported by each carrier set which, when completed, the four individual components are brought together and placed in the correct position or registration guided by guide holes. 20 carriers are designed for each component. With the method known from the above-mentioned European patent, a total of four separate progress steps of the type mentioned in the preamble to prepare four subcomponents of the finished pressure key coupler must be carried out for the production of a pressure key coupler. As will immediately be understood, the process known from the above-mentioned European patent is very materially demanding, since a single metal band is used to manufacture each of the four individual components of the pressure key coupler, which is manufactured in accordance with the above-mentioned method and second, very complicated, since the four separate metal carriers, each with its own single component, must be brought together exactly during the final assembly stage, at which the bottom housing component, the switching element, the tap member and the top housing component are assembled.

En om mulig væsentligere begrænsning ved denne kendte teknik er 35 imidlertid, at det i overensstemmelse med denne ikke umiddelbart er 5However, one possible limitation of this prior art is that, in accordance with this, it is not immediately 5

muligt at foretage en automatiseret afprøvning af en færdigt samlet tryktastomkobler, der understøttes af bærebåndene hørende til de fire ovenfor omhandlede enkeltkomponenter forud for adskillelse af tryk-tastomkobleren fra bærebåndene, da det med tryktastomkobleren under-5 støttet i de metalliske bærebånd ikke er muligt at afgøre, om der er elektrisk forbindelse gennem tryktastomkobleren i den ene eller den anden tilstand, da der uafhængigt af, om taporganet er aktiveret eller ej, og altså om tryktastomkobleren er i sin første eller anden tilstand, er kortsluttet elektrisk ledende forbindelse gennem metal-10 båndene. Det er i overensstemmelse med denne kendte teknik forud for afprøvning af tryktastomkobleren nødvendigt at adskille den færdigt samlede tryktastomkobler fra sine understøtningsbånd, hvorefter tryktastomkobleren, såfremt der skal foretages en automatiseret afprøvning, skal understøttes i andre dertil indrettede understøt-15 ningsorganer, i hvilke tryktastomkobleren skal føres til en prøvestation.it is possible to carry out an automated test of a final assembled pressure key coupler supported by the carrier belts of the four above-mentioned single components prior to separation of the pressure key switch from the carrier belts, since with the pressure key switch supported in the metallic carriers it is not possible whether there is electrical connection through the pressure key switch in one or the other state, regardless of whether the tap member is activated or not, and thus whether the pressure key switch is in its first or second state, electrically conductive connection is shorted through the metal bands. . In accordance with this prior art, prior to testing the pressure key switch, it is necessary to separate the completed assembled pressure key switch from its support bands, after which, if an automated test is to be performed, support must be provided in other support switches arranged therein, in which pressure key switches are provided. is taken to a test station.

Et primært formål med den foreliggende opfindelse er at tilvejebringe en fremgangsmåde af den indledningsvis angivne art, hvilken fremgangsmåde sammenlignet med den fra ovennævnte europæiske patentskrift 20 kendte teknik giver en betydelig materialebesparelse, er simplere og yderligere muliggør en automatiseret afprøvning af en færdigt samlet tryktastomkobler, forud for adskillelse af denne fra det tilhørende understøttende bærebånd, altså en afprøvning af en færdigt samlet tryktastomkobler i middelbar fortsættelse af fremstillingstrinnene.A primary object of the present invention is to provide a method of the kind described in the preamble, which, in comparison with the prior art of the above-mentioned European patent 20 provides considerable material savings, is simpler and further enables automated testing of a complete assembled pressure key coupler, prior to for separating it from the associated supporting carrier, i.e. a test of a final assembled pressure key coupler in the immediate continuation of the manufacturing steps.

25 Det ovenfor angivne formål opnås i overensstemmelse med opfindelsen med en fremgangsmåde af den indledningsvis angivne art, hvilken fremgangsmåde i overensstemmelse med opfindelsen er ejendommelig ved, at bundhuskomponenten under punkt c) støbes med i det mindste én flig, der strækker sig udefter fra en ydre sidevæg af bundhuskom-30 ponenten og er støbt til bærebåndet til etablering af mekanisk forbindelse mellem bundhuskomponenten og bærebåndet, og at fremgangsmåden yderligere i følgen af trin omfatter følgende to afslutningstrin: h) afprøvning af den under trin a)-g) frembragte tryktastomkobler i 35 en prøvestation, medens bundhuskomponenten er mekanisk forbundet tilThe object stated above is achieved in accordance with the invention by a method of the type mentioned in the preamble, characterized in that the bottom housing component of point c) is molded with at least one tab extending outwardly from an outer side wall of the bottom housing component and is molded to the carrier to establish mechanical connection between the bottom housing component and the carrier, and the method further comprises the following two finishing steps: h) testing the pressure key coupler provided in steps a) to g a test station while the bottom housing component is mechanically connected to

15 Som man vil forstå bliver det med den for opfindelsen karakteristiske flig, der støbes ragende ud fra en ydre sidevæg af bundhuskomponenten muligt at adskille terminalkomponenterne fra bærebåndet og dermed eliminere den direkte elektriske kortslutning mellem terminalkomponenterne via bærebåndet samtidigt med, at det bliver muligt at 20 afprøve den færdige tryktastomkobler i en prøvestation, medens tryktastomkobleren stadigt holdes understøttet af bærebåndet. Hermed kan den færdige afprøvning og bestemmelse af, om den færdigt samlede tryktastomkobler er en korrekt fungerende tryktastomkobler, eller om den er behæftet med fejl, foretages i umiddelbar tilknytning til 25 selve fremstillingstrinnet.As will be appreciated, with the tab characteristic of the invention molded protruding from an outer side wall of the bottom housing component, it is possible to separate the terminal components from the carrier and thereby eliminate the direct electrical short-circuit between the terminal components via the carrier, while allowing test the completed pressure key coupler in a test station while the pressure key coupler is still supported by the carrier. Hereby, the final testing and determination of whether the completed assembled pressure key coupler is a properly functioning pressure key coupler or whether it is defective can be made directly in connection with the manufacturing step itself.

Den foreliggende opfindelse vedrører desuden en tryktastomkobler med et hus af et isolerende materiale med ydre sidevægge et omkoblings-element, der er indesluttet i huset, og i det mindste to metalliske terminalkomponenter, der hver har: 30 en ydre terminal, der strækker sig udefter fra en ydre sidevæg af huset og afgrænser en ydre terminalende, samt et elektrisk kontaktorgan, der elektrisk samvirker med omkoblingselementet, og som er indesluttet i huset og integreret forbundet til den nævnte ydre terminal i en ende af denne modsat 35 den nævnte ydre terminalende, 7The present invention further relates to a pressure key coupler having a housing of an insulating material having outer side walls a switching element enclosed within the housing, and at least two metallic terminal components each having: an outer terminal extending from the outside an outer side wall of the housing defining an outer terminal end, and an electrical contact member electrically cooperating with the switching element, which is enclosed in the housing and integrally connected to said outer terminal at one end thereof opposite said outer terminal end,

Tryktastomkobleren ifølge opfindelsen kan være implementeret på 5 vilkårlig måde, men er i overensstemmelse med den foretrukne udførelsesform for tryktastomkobleren ifølge opfindelsen af den art, der har et elastisk komprimerbart eller sammentrykkeligt legeme, der er placeret mellem taporganet og metalskiven.The pressure key switch of the invention may be implemented in any manner, but is in accordance with the preferred embodiment of the pressure key switch of the invention having a resiliently compressible or compressible body located between the tab member and the metal disk.

Dette elastisk komprimerbare eller sammentrykkelige legeme tjener, 10 således som det er antydet ovenfor, og således som det vil blive forklaret nedenfor, primært to formål, for det første at give en bevægelsesforlængelse, dvs. at forlænge den bevægelse, som metalskiven foretager ved skift fra den første til den anden tilstand eller vice versa, til en længere bevægelse af det metalskiveaktive -15 rende taporgan, og at forsegle metalskivens periferiske kant og følgelig beskytte metalskiven mod korroderende gasser og eventuelt høje temperaturer.This elastically compressible or compressible body serves, as indicated above, and as will be explained below, primarily for two purposes, firstly to provide an extension of motion, i.e. to extend the movement of the metal disk by changing from the first to the second state or vice versa to a longer movement of the metal disk-active tap member, and to seal the peripheral edge of the metal disk and consequently protect the metal disk from corrosive gases and possibly high temperatures. .

Tryktastomkobleren ifølge opfindelsen er i overensstemmelse med dette sidst angivne formål med det elastisk komprimerbare eller sammentryk -20 kelige legeme fortrinsvis en tryktastomkobler, der kan benyttes i forbindelse med såkaldt SMT-teknik (SMT: Surface Mounting Technique, overflademontering), dvs. som kan tåle loddemetalmateriale, såsom tin, der opvarmes til en temperatur på fx 240°C i fx 60 s. For at muliggøre, at tryktastomkobleren kan tåle sådanne høje temperaturer, 25 er bundhuskomponenten og tophuskomponenten fortrinsvis fremstillet af et højtemperaturbestandigt plastmateriale, såsom høj krystallinske copolymerer, epoxyharpiks, olefin-carbonmonooxidcopolymerer, polycar-bonater, polyolef insulf onater, fx polyethylensulf onat, PES, eller polyethylen-terephthalater, fx PETP eller PET.According to this last stated purpose of the elastically compressible or compressible body, the pressure key switch of the invention is preferably a pressure key switch which can be used in connection with so-called SMT (Surface Mounting Technique, surface mounting), ie. which can withstand solder material such as tin heated to a temperature of, for example, 240 ° C for, for example, 60 s. To allow the pressure switch coupler to withstand such high temperatures, the bottom housing component and the top housing component are preferably made of a high temperature resistant plastic material such as high crystalline copolymers, epoxy resin, olefin-carbon monoxide copolymers, polycarbonates, polyolefinsulfonates, e.g., polyethylene sulfonate, PES, or polyethylene terephthalates, e.g., PETP or PET.

30 For at tætne den hvælvede metalskive og dermed beskytte den hvælvede metalskive mod at blive udsat for gasser, såsom korroderende gasser, og for høje temperaturer, fx ved den ovennævnte overflademonterings-proces, kan tryktastomkobleren ifølge opfindelsen yderligere have sit taporgan, legeme og hvælvede metalskive anbragt koaksialt i forhold 9In order to seal the vaulted metal disk and thus protect the vaulted metal disk from being exposed to gases such as corrosive gases and to high temperatures, for example, in the above surface mounting process, the pressure key coupler of the invention may further have its tap member, body and vaulted metal disk. coaxially positioned 9

til hinanden, idet det elastisk sammentrykkelige legeme fortrinsvis har en cirkulær membrandel med en cirkulær vulst og en central tap-del, som udgør en elastisk sammentrykkelig del til transmission af aktiveringen af taporganet til den hvælvede metalskive, der fortrins-5 vis er anbragt inden for den periferiske vulst af membrandelen, så at vulsten tætner langs den periferiske kant af den hvælvede metalskive og dermed tætner den hvælvede metalskive i forhold til omgivelserne.preferably, the elastically compressible body preferably has a circular diaphragm portion with a circular bead and a central tab portion which constitutes an elastically compressible portion for transmitting the actuation of the tab member to the vaulted metal disk, preferably disposed within the circumferential bead of the membrane portion so that the bead seals along the circumferential edge of the vaulted metal disk and thereby seals the vaulted metal disk relative to its surroundings.

I den ovenfor beskrevne foretrukne udførelsesform for tryktastom-kobleren ifølge opfindelsen er det elastisk sammentrykkelige legeme 10 fortrinsvis fremstillet af silicone gummi, og den hvælvede metalskive er fortrinsvis fremstillet af CuBe-folie med en tykkelse på fx 0,075 mm.In the preferred embodiment described above for the pressure key coupler of the invention, the resilient compressible body 10 is preferably made of silicone rubber, and the vaulted metal disk is preferably made of CuBe foil having a thickness of, for example, 0.075 mm.

tionstrin, der skematisk er angivet ved positioner angivet med henvisningsbetegnelserne 1-5. I position 1 tilvejebringes der en metalplade, som udgør en kontinuerlig bane af en metalfolie 10. I position 2 bearbejdes metalfoliebanen 10 i et stanseværktøj, som ikke er vist 5 i fig. 1, og bearbejdes til to bærebånd 11 og 12, mellem hvilke der strækker sig to terminalaggregater 13 og 14. Som det vil fremgå af beskrivelsen nedenfor, bearbejdes hvert af terminalaggregaterne 13 og 14 i et efterfølgende produktions trin til to terminaler. Terminalag-gregateme 13 og 14 er således integreret forbundet til bærebåndene 10 11 og 12 via ender af terminalaggregaterne, hvilke ender er beregnet til at skulle udgøre de ydre terminalender af de ovennævnte terminaler. Som det fremgår af fig. 1, bearbejdes terminalaggregatet 13 til en form, som afgrænser en centralt nedbøjet stang 15, fra hvilken en kontaktstang ‘17, strækker sig mod det tilgrænsende terminalaggregat 15 14. Den ydre ende af kontakts tangen 17 modsat den nedbøjede stang 15 er yderligere bearbejdet til en hvælvet kontaktplade 19. Som det ligeledes fremgår af fig. 1, bearbejdes terminalaggregatet 14 også til en form, som afgrænser en centralt nedbøjet del 16, fra hvilken der strækker sig to kontakts tænger 18 mod det tilgrænsende terminal-20 aggregat 13. Kontakts tængerne 18 har yderligere forhøjede, ydre kontaktdele 20.10, which are schematically indicated at positions indicated by reference numerals 1-5. In position 1, a metal sheet is provided which constitutes a continuous web of a metal foil 10. In position 2, the metal foil web 10 is processed in a punching tool not shown 5 in FIG. 1, and processed into two carriers 11 and 12, between which extend two terminal assemblies 13 and 14. As will be apparent from the description below, each of the terminal assemblies 13 and 14 is machined in a subsequent production step into two terminals. Thus, the terminal aggregates 13 and 14 are integrally connected to the carriers 10 11 and 12 via ends of the terminal assemblies, which ends are intended to constitute the outer terminal ends of the above terminals. As shown in FIG. 1, the terminal assembly 13 is machined into a mold defining a centrally deflected rod 15, from which a contact rod '17 extends toward the adjacent terminal assembly 14 14. The outer end of the contact pliers 17 opposite the deflected rod 15 is further machined to a vaulted contact plate 19. As also shown in FIG. 1, the terminal assembly 14 is also machined into a mold defining a centrally deflected portion 16 from which extends two contact pliers 18 toward the adjacent terminal 20 assembly. The contact pliers 18 have further elevated outer contact portions 20.

I position 3 støbes en bundhuskomponent 22 omkring de ovenfor beskrevne komponenter 15-20 af terminalaggregateme 13 og 14. Bundhuskomponenten 22 støbes med en central udsparing 23, der afgrænser en 25 periferisk inderflade 24 og en bundflade 25, fra hvilken kontaktpladen 19 og de forhøjede, ydre kontaktdele 20 rager opefter. Bundhus-komponenten 22 afgrænser yderligere en topflade 26, en bundflade, som ikke er vist i fig. 1, en første ydre sideflade 27, der vender mod bærebåndet 12 og en anden ydre sideflade 28. Fladerne 26, 27 og 28 30 står vinkelret på hinanden. Bundhuskomponenten 22 har yderligere en bundflade, som ikke er vist i fig. 1, som er parallel med topfladen 26, samt to ydre sideflader, der ikke er vist i fig. 1, og som er parallelle med henholdsvis den første og den anden ydre sideflade 27 og 28. Fra den første ydre sideflade 27 og endvidere fra den anden 35 ydre sideflade, som ikke er vist i fig. 1, og som er parallel med fladen 27, strækker der sig bæreflige 29. Bærefligene 29 er støbt 11In position 3, a bottom housing component 22 is molded around the components 15-20 described above by terminal assemblies 13 and 14. The bottom housing component 22 is molded with a central recess 23 defining a peripheral inner surface 24 and a bottom surface 25 from which the contact plate 19 and the elevated outer contact portions 20 protrude upwards. The bottom housing component 22 further defines a top surface 26, a bottom surface not shown in FIG. 1, a first outer side surface 27 facing the carrier 12 and a second outer side surface 28. The surfaces 26, 27 and 28 are perpendicular to each other. The bottom housing component 22 further has a bottom surface not shown in FIG. 1, which is parallel to the top surface 26, and two outer side surfaces not shown in FIG. 1, which are parallel to the first and second outer side surfaces 27 and 28. respectively, from the first outer side surface 27 and further from the second outer side surface, not shown in FIG. 1, and which is parallel to the surface 27, extends supporting tabs 29. The supporting tabs 29 are molded 11

ud i ét med bundhuskomponenten 22 og støbt til de tilhørende bærebånd 11 og 12.integral with the bottom housing component 22 and molded to the associated carriers 11 and 12.

Som det fremgår af fig. 1, er bundhuskomponenten 22 i sin top flade 26 og sine ydre sideflader 27 og 28 udformet med indsnit, der passer til 5 henholdsvis en tophuskomponent 30 og ekstra komponenter, som vil blive beskrevet nedenfor.As shown in FIG. 1, the bottom housing component 22 is at its top surface 26 and its outer side surfaces 27 and 28 formed with incisions corresponding to a top housing component 30 and additional components, respectively, which will be described below.

I den ovenfor beskrevne, støbte bundhuskomponent 22 anbringes der en hvælvet metalskive 31, som har sin hvælving vendende opefter, dvs. udefter fra bundhuskomponenten 22's udsparing 23. Den hvælvede metal-10 skive 31 er i sin normalt hvælvede form i kontakt med kontaktdelene 20, men ikke i kontakt med den centrale kontaktplade 19, og etablerer følgelig ikke i sin normalt hvælvede form elektrisk ledende forbindelse mellem kontaktpladen 19 og de ydre kontaktdele 20 og dermed mellem terminalaggregaterne 14 og 13. Den hvælvede metalskive 31 har 15 på sin øverste eller konvekse sideflade en central coating 32 af et akustisk dæmpningsmateriale, fx silicone, hvilken coating tjener det formål at ændre den ubehagelige og skarpe støj, som genereres af en udæmpet, hvælvet metalskive, når metalskiven deformeres fra sin hvælvede form til en deformeret form og vice versa til en mere be-20 hagelig dæmpet lyd. Oven på den hvælvede metalskive 31 er der anbragt en gummikomponent 33, der omfatter to integreret forbundne dele, en membrandel 34 og en tapdel 35. Membrandelen 34 har, som det fremgår af fig. 1, en større ydre diameter end den hvælvede metalskive 31, og har endvidere på sin underside, således som det fremgår af fig. 2, en 25 periferisk vulst 36. Vulsten 36 tjener det formål at tætne langs den ydre periferiske kant af den hvælvede metalskive 31.In the above-described molded bottom housing component 22 is placed a vaulted metal disk 31 having its vault facing upwards, i.e. outwardly from the recess 23 of the bottom housing component 22. The vaulted metal disc 31 in its normally vaulted form contacts the contact portions 20 but not in contact with the central contact plate 19, and consequently does not establish in its normally vaulted form electrically conductive connection between the contact plate 19 and the outer contact portions 20 and thus between the terminal assemblies 14 and 13. The vaulted metal disc 31 has on its upper or convex side surface a central coating 32 of an acoustic damping material, for example silicone, which coating serves to change the unpleasant and sharp noise , which is generated by an attenuated, vaulted metal disk as the metal disk is deformed from its vaulted shape to a deformed shape and vice versa to a more comfortable muted sound. On top of the vaulted metal disk 31, there is arranged a rubber component 33 comprising two integrally connected parts, a diaphragm member 34 and a pin member 35. As shown in FIG. 1, a larger outer diameter than the vaulted metal disc 31, and further has on its underside, as can be seen in FIG. 2, a peripheral bead 36. The bead 36 serves the purpose of sealing along the outer peripheral edge of the vaulted metal disk 31.

Tapdelen 35 er en hul del, der er elastisk deformerbar og tjener det formål at transmittere mekanisk kraft fra en trykknap 37, til hvilken der tilføres mekanisk kraft, til den hvælvede metalskive og yderli-30 gere det formål at forøge trykknappen 37's slaglængde sammenlignet med den hvælvede metalskives slaglængde, når metalskiven deformeres eller får lov til at vende tilbage til sin normalt hvælvede form fra sin deformerede form ved den elastiske deformation af tapdelen 35.The pin portion 35 is a hollow portion which is resiliently deformable and serves the purpose of transmitting mechanical force from a push button 37 to which mechanical force is applied to the vaulted metal disk and further the purpose of increasing the stroke length of the push button 37 compared to the the length of the vaulted metal disc when the metal disc is deformed or allowed to return to its normally vaulted shape from its deformed shape by the elastic deformation of the tab member 35.

Som det fremgår af fig. 2, har membrandelen 34 ved sin underside en udragende del 38, der tjener det formål at etablere kontakt med den centrale del af den kuppelformede eller hvælvede metalskive 31, når tapdelen 35 aktiveres og tvinges nedefter ved hjælp af trykknappen 5 37. Når den hvælvede metalskive 31 og gummikomponenten 33 er anbragt i bundhuskomponenten 22's udsparing 23, anbringes tophuskomponenten 30 med trykknappen 37 anbragt i tophuskomponenten 30's centrale åbning oven på bundhuskomponenten 22 og fastgøres til denne. Tophuskomponenten 30 er, som det fremgår af fig. 1, udformet med en cen-10 tral cylindrisk bunddel, der passer i udsparingen 23 i en snaplås-ning, således som det fremgår af fig. 2, og yderligere udformet med nedefter ragende finner til samvirken med de ovennævnte indsnit i bundhuskomponenten 22's topflade 26. Tryknappen 37's bevægelse i i tophuskomponenten 30's åbning 39 styres af finner 40, der strækker 15 sig udefter fra trykknappen 37's periferiske ydre sideflade, ved den nederste kant af trykknappen, således som det fremgår af fig. 1, idet finnerne 40 er indrettet til at samarbejde med indsnit i indervæggen af huskomponenten 30's åbning 39.As shown in FIG. 2, the membrane portion 34 has at its underside a protruding portion 38 which serves to establish contact with the central portion of the domed or vaulted metal disk 31 when the pin portion 35 is actuated and forced downwardly by the push button 5 37. When the vaulted metal disk 31 and the rubber component 33 is positioned in the recess 23 of the bottom housing component 22, the top housing component 30 is positioned with the pushbutton 37 located in the central opening of the top housing component 30 on top of the bottom housing component 22 and secured thereto. The top housing component 30 is as shown in FIG. 1, formed with a central cylindrical bottom member that fits in the recess 23 in a snap-lock, as shown in FIG. 2, and further configured with downwardly projecting fins to cooperate with the aforementioned incisions in the top surface 26. of the bottom housing component 22 in the opening 39 of the top housing component 30 is controlled by fins 40 extending outwardly from the peripheral outer side surface of the pushbutton 37, at the lower edge. of the pushbutton, as shown in FIG. 1, the fins 40 being arranged to cooperate with incisions in the inner wall of the opening 39 of the housing component 30.

I position 4 er det ovenfor beskrevne tryktastomkobleraggregat samlet 20 af bundhuskomponenten 22, tophuskomponenten 30 og trykknappen 37. Fra den første ydre sideflade 27 og fra den modstående, dermed parallelle sideflade rager terminalaggregaterne 13 og 14 udefter. I position 4 adskilles terminalaggregaterne 13 og 14 fra bærebåndene 11 og 12 ved terminalaggregaternes ydre ender. Tryktastomkobleraggregatet er 25 følgeligt forbundet til bærebåndene 11 og 12 alene via fligene 29.In position 4, the pressure key coupler assembly described above is assembled 20 by the bottom housing component 22, the top housing component 30 and the push button 37. From the first outer side surface 27 and from the opposite, thus parallel side surface, the terminal assemblies 13 and 14 extend outward. In position 4, the terminal assemblies 13 and 14 are separated from the carriers 11 and 12 at the outer ends of the terminal assemblies. Accordingly, the pressure key coupler assembly 25 is connected to the carriers 11 and 12 alone via the tabs 29.

Når tryktastomkobleraggregatet forlader position 4, bøjes de ydre terminaler, som afgrænses af de dele af terminalaggregaterne 13 og 14, som strækker sig udefter fra bundhuskomponenten 22, nedefter, således som det fremgår af det i position 5 i fig. 1 viste tryktas-30 tomkobleraggregat. Ved adskillelse af terminalaggregaterne 13 og 14 fra bærebåndene 11 og 12 elimineres kortslutningsforbindelsen mellem terminalaggregaterne 13 og 14 via bærebåndene 11 og 12. Tryktastomkobleraggregatet kan, medens det stadig mekanisk understøttes af bærebåndene 11 og 12 via fligene 29, som forbinder bundhuskomponenten 35 22 med bærebåndene 11 og 12, i position 5 testes i en automatisk elektrisk prøvestation. Prøvestationen er skematisk angivet med en 13As the push-button coupler assembly exits position 4, the outer terminals bounded by the portions of the terminal assemblies 13 and 14 extending outwardly from the bottom housing component 22 are bent downward as shown in position 5 of FIG. 1, the printed pocket empty coupler assembly. By separating the terminal assemblies 13 and 14 from the straps 11 and 12, the short-circuit connection between the terminal assemblies 13 and 14 via the straps 11 and 12. is eliminated, while still mechanically supported by the straps 11 and 12 via the lugs 29 connecting the bottom housing component 22 and 12, in position 5, are tested in an automatic electrical test station. The test station is schematically indicated by a 13

afprøvningsblok 41, som bevæges opefter fra den i fig. 1 viste position, så at blokken optager de ydre ender af terminalerne, som af-grænses af terminalaggregaterne 13 og 14, i åbninger 42 i blokken 41.test block 41 which is moved upwardly from the one shown in FIG. 1 so that the block accommodates the outer ends of the terminals bounded by the terminal assemblies 13 and 14 in openings 42 of the block 41.

I åbningerne 42 er der tilvejebragt metalkontaktorganer til etabler-5 ing af elektrisk ledende kontakt med terminalaggregaterne 13 og 14, hvilke organer er forbundet til et prøvekredsløb, som ikke er vist i fig. 1, og som er i stand til at bestemme forekomsten eller fraværet af en kortslutningstilstand. Ved yderligere aktivering af knappen 37 og deraf følgende deformation af den hvælvede metalskive 31 fra dens 10 normalt hvælvede form til dens deformerede form ved samvirken med gummikomponenten 33 og stadig overvågning af tilstedeværelsen eller fraværet af en kortslutningstilstand mellem terminalerne 13 og 14 afprøves tryktastomkobleraggregatet på simpel måde. Formålet er at bestemme, om tryktastomkobleraggregatet er en korrekt fungerende 15 tryktastomkobler, som i sin inaktiverede tilstand ikke etablerer elektrisk ledende forbindelse mellem terminalerne 13 og terminalerne 14, og som i sin aktiverede tilstand aktiverer elektrisk ledende forbindelse mellem terminalerne 13 og 14. Forudsat tryktastomkobleraggregatet er identificeret som et korrekt fungerende tryktastomkobler-20 aggregat, adskilles det fra bærebåndene 11 og 12 ved, at tryktastomkobleraggregatet skæres eller brækkes fri af fligene 29.In the openings 42, metal contact means are provided for establishing electrically conductive contact with the terminal assemblies 13 and 14 which are connected to a test circuit not shown in FIG. 1 and capable of determining the presence or absence of a short-circuit state. By further activating the button 37 and consequent deformation of the vaulted metal disk 31 from its normally vaulted shape to its deformed shape by the interaction with the rubber component 33 and still monitoring the presence or absence of a short-circuit state between the terminals 13 and 14, the pressure key coupler assembly is tested in a simple manner. . The purpose is to determine whether the pressure key switch assembly is a properly functioning pressure key switch which, in its inactivated state, does not establish electrically conductive connection between terminals 13 and terminals 14, and in its activated state activates electrically conductive connection between terminals 13 and 14. Provided the pressure key switch assembly is identified as a properly functioning pressure key coupler assembly, it is separated from the carriers 11 and 12 by cutting or breaking the pressure key coupler assembly by the tabs 29.

I fig. 1 er bærebåndene 11 og 12 udformet med gennemgående huller 43 og 44. Den ovenfor beskrevne proces til fremstilling af et tryktas-tomkobleraggregat ifølge opfindelsen er angivet ovenfor og udføres 25 ved, at båndet 10 føres fra position 1 til position 5 ved hjælp af velkendte datamatstyrede mekaniske fremføringsorganer. Hullerne 43 og 44 tjener følgelig det formål at samvirke med gribeorganer til fremføring af båndet 10 og yderligere eller i stedet med fx optiske eller nærhedsdetekterende organer til at informere den processtyrende data-30 mat om banens placering eller bærebåndene 11's og 12's placering i forhold til en tiltænkt position i en af de i fig. 1 viste positioner 1-5.In FIG. 1, the carrier belts 11 and 12 are formed with through holes 43 and 44. The above-described process for producing a pressure sensor coupler assembly according to the invention is set forth above and is carried out 25 by passing the belt 10 from position 1 to position 5 by means of well known computer controlled mechanical conveying means. The holes 43 and 44 thus serve to cooperate with gripping means for advancing the tape 10 and further or instead with, for example, optical or proximity detecting means for informing the process control data of the location of the web or the position of the carriers 11 and 12 relative to a web. intended position in one of the FIG. 1 positions 1-5.

I en produktionslinie til fremstilling af den ovenfor under henvisning til fig. 1 og 2 beskrevne tryktastomkobler kan metalpladen 10, 5 af hvilken tryktastomkobleren fremstilles, føres frem gennem et antal bearbejdningsstationer. Metalpladen 10 kan i stedet være stationær, og produktionsstationerne kan bevæges i forhold til metalpladen. Produktionslinien kan yderligere udgøre en vilkårlig hensigtsmæssig kombination af de ovenfor beskrevne muligheder, nemlig fremføringen 10 af metalpladen 10 i forhold til stationerne og bevægelsen af stationerne i forhold til metalpladen. Et meget vigtigt aspekt af den foreliggende opfindelse er imidlertid den permanente fiksering af tryktastomkobleren i forhold til metalpladen 10 eller til bærebåndene II og 12, indtil tryktastomkobleren er blevet afprøvet og positivt 15 identificeret som en korrekt fungerende tryktastomkobler. Tryktastomkobleren skal således ikke overføres fra sin produktionslinie til en prøveopstilling, da tryktastomkobleren er permanent fikseret til bærebåndene 11 og 12 og følgelig holdes i en fast position i forhold til værktøjerne i de enkelte positioner 2-5, specielt i en fast posi-20 tion i forhold til blokken 41, som udgør en del af den i position 5 i fig. i viste afprøvningsstation.In a production line for preparing the above with reference to FIG. 1 and 2, the metal key 10, 5, from which the pressure key switch is manufactured, can be advanced through a number of machining stations. The metal plate 10 may instead be stationary and the production stations can be moved relative to the metal plate. The production line may further constitute any suitable combination of the options described above, namely, the feed 10 of the metal plate 10 relative to the stations and the movement of the stations relative to the metal plate. However, a very important aspect of the present invention is the permanent fixation of the pressure key coupler with respect to the metal plate 10 or of the carriers II and 12 until the pressure key coupler has been tested and positively identified as a properly functioning pressure key coupler.
