(54) Tidsfors lnkels esanordning til aktivering af elektriske kon= takter.(54) Timing key switching device for activating electrical contacts.
Den foreliggende opfindelse angår en tidsforsinkelses-anordning til aktivering af hjælpekontakter anbragt i et hus, som kan sammenkobles med en kontaktor, hvilken anordning omfatter et regulerbart pneumatisk tidsforsinkelsesorgan, en hjælpekontaktholder, et koblingsorgan, som samvirker med et betjeningsorgan i kon-taktoren og en lås, som er egnet til at holde kontaktholderen i en 0 første stilling, hvor koblingsorganet bevirker spænding af tidsfor- ^ sinkelsesorganet, og tidsforsinkelsesorganet bevirker efter et D vist tidsrum frigivelse af låsen, som tillader kontaktholderen at j. indtage en anden stilling under indvirkning af en returfjeder.The present invention relates to a time delay device for activating auxiliary contacts located in a housing which can be coupled to a contactor, the device comprising an adjustable pneumatic time delay means, an auxiliary contact holder, a coupling means which cooperates with an actuator in the contactor and a lock. , which is suitable for holding the contact holder in a first position, where the coupling means causes tension of the time delay means and after a time shown the time means causes the release of the lock which allows the contact holder to j. occupy another position under the influence of a return spring.
I kendte apparater af den ovennævnte art, se f.eks.In known apparatus of the aforementioned kind, see e.g.
£ schweizisk patent nr. 513.503, optræder der vanskeligheder, når kob- a 2 143672 lingsorganet skal sammenkobles med betjeningsorganet. Disse vanskeligheder skyldes hovedsageligt, at en for nøjagtig styring af koblingsorganet ikke altid tillader, at dette forskyder sig i forhold til betjeningsorganet, navnlig på grund af fremstillingstolerancerne, som påvirker dels kontaktorens hus og dels apparatets hus.In Swiss Patent No. 513,503, difficulties arise when the coupling means must be coupled to the control means. These difficulties are mainly due to the fact that too precise control of the coupling means does not always allow this to shift with respect to the actuator, in particular because of the manufacturing tolerances which affect both the contactor housing and the device housing.
Desuden resulterer ethvert udført forsøg på at give koblingsorganet mere frihed i en forøgelse af rumfanget af tidsforsinkelsesanordningen, da de med dette organ forbundne dele og navnlig kontaktholderen ligeledes skal reagere på bevægelser med større amplitude.Furthermore, any attempt made to give the coupling means more freedom results in an increase in the volume of the time delay device, since the parts associated with that member and in particular the contact holder must also respond to movements of greater amplitude.
Formålet med den foreliggende opfindelse er at afhjælpe de ovennævnte ulemper og uden at bevirke en væsentlig forøgelse af anordningens volumen, idet anordningen i hovedsagen skal være af samme bredde som kontaktoren, den skal forbindes med.The object of the present invention is to overcome the aforementioned disadvantages and without causing a substantial increase in the volume of the device, the device having to be substantially the same width as the contactor with which it is to be connected.
Ifølge opfindelsen opnås dette ved, at koblingsorganet findes på et bevægeligt organ, der ved hjælp af to særskilte led er forbundet med en første svingelig vægtstang og med en anden svingelig vægtstang, idet den ene ende af den første vægtstang samvirker med en del, hvis forskydning er styret af et udvideligt tidsforsinkelsesorgan, medens den ene ende af den anden vægtstang samvirker med en svingelig kontaktholder, der har form af en ring, som omgiver tidsforsinkelsesorganet, og som bærer hjælpekontakterne.According to the invention, this is achieved by the coupling means being provided on a movable member which is connected by two separate links to a first pivotal bar and to a second pivotal bar, one end of the first bar cooperating with a part whose displacement is controlled by an extensible time delay means while one end of the other lever cooperates with a pivotal contact holder which is in the form of a ring surrounding the time delay means and which carries the auxiliary contacts.
Opfindelsen skal herefter forklares nærmere under henvisning til tegningen, hvor fig. 1 og 2 viser en udførelsesform for en kontakttidsforsinkelsesanordning ifølge opfindelsen set fra siden, når kontaktoren, som den er i forbindelse med, ikke er aktiveret, fig. 3 et delbillede set franeden og fig. 4 en kontakttidsforsinkelsesanordning ifølge opfindelsen set fra siden, når kontaktoren, som den står i forbindelse med, er aktiveret.The invention will now be explained in more detail with reference to the drawing, in which fig. Figures 1 and 2 show an embodiment of a contact time delay device according to the invention viewed from the side when the contactor with which it is connected is not activated; 3 is a front elevational view, and FIG. 4 shows a side time contact delay device according to the invention when the contactor with which it is connected is activated.
Som vist i fig. 1 betegner 1 huset for en tidsstyret hjælpekontaktblok, som er fastgjort på huset 14 for en kontaktor eller et relæ og modtager sin bevægelse fra dette ved hjælp af en kobling, som på den ene side omfatter en svalehale 11, der indgår i tidsforsinkelsesanordningen, og på den anden side en klo 12, som indgår i den bevægelige del 13 i kontaktoren.As shown in FIG. 1, 1 denotes the housing of a timed auxiliary contact block which is secured to the housing 14 of a contactor or relay and receives its movement therefrom by means of a coupling which, on the one hand, comprises a dovetail 11 included in the time delay device, and on on the other side, a claw 12 which is included in the moving part 13 of the contactor.

Kronometerenheden, som er anbragt foroven i huset 1, består af en bælg 2, som har tendens til at udvide sig under indvirkning af en indvendig fjeder 32 og en indstillingsknap 3. Når den nederste del 24 af bælgen skubbes opad, frembyder den ikke nogen modstand på grund af åbningen af en passende orienteret ventil. Når bælgen under indvirkning af den indre fjeder 32 søger at genantage sin begyndelsesform, forsinkes den nedadgående bevægelse i retning af pilen F på grund af drøvlingen, som luften, der skal trænge gen-nem indstillingsknappen, udsættes for.The chronometer unit located at the top of housing 1 consists of a bellows 2 which tends to expand under the action of an internal spring 32 and an adjusting knob 3. When the lower portion 24 of the bellows is pushed upwards, it does not present any resistance. due to the opening of a suitably oriented valve. When the bellows, under the action of the inner spring 32, seeks to recapture its initial form, the downward movement in the direction of the arrow F is delayed due to the turbulence to which the air which is to penetrate the adjusting knob is exposed.
Hele apparatet i fig. 1 er vist i hviletilstanden, dvs. kontaktoren er deaktiveret, bælgen er udvidet, og kontaktholderen 4 er i sin inaktive stilling.The entire apparatus of FIG. 1 is shown in the idle state, i.e. the contactor is deactivated, the bellows are expanded and the contact holder 4 is in its inactive position.
I denne stilling ligger kontakten 7 an mod ikke viste ledende ansatse, og kontakten 6 er adskilt fra sine ligeledes ikke viste ansatse. Det vil bemærkes, at kontaktholderen består af en ring, som vipper omkring tappen 5, se også fig. 3, og at bælgen 2 går gennem denne ring. Årsagen til dette arrangement skal forklares senere.In this position, the contact 7 rests against the conductors not shown, and the contact 6 is separate from its also not shown conductors. It will be noted that the contact holder consists of a ring which tilts around the pin 5, see also fig. 3, and the bellows 2 passes through this ring. The reason for this arrangement must be explained later.
Som det fremgår af fig. 1, danner svalehalen 11 en del af en bevægelig styreglider lo med form som et T med arme 15 og 16.As shown in FIG. 1, the dovetail 11 forms part of a movable guide slider 10 in the form of a T with arms 15 and 16.
Denne glider er ophængt i to led 18 og 17, der også er forbundet med to vægtstænger henholdsvis 19 og 2o. Disse vægtstænger er selv svin-geligt lejret i huset 1 ved hjælp af omdrejningstappe henholdsvis 21 og 22.This slider is suspended in two links 18 and 17, which are also connected to two levers 19 and 20 respectively. These levers are themselves stably mounted in housing 1 by means of pivots 21 and 22, respectively.
Det ses tydeligt, at hvis disse to vægtstænger ikke havde noget omdrejningspunkt, kunne styreglideren glide nedad i retning af pilen F. Denne bevægelse er i realiteten begrænset på grund af, at deres ender henholdsvis 36 og 32 rammer anslag, hvoraf det første findes på selve kontaktholderen 4, der er påvirket af et elastisk element 9, og det andet findes på enden 24 af selve bælgen og er påvirket af den indre fjeder 32. Det nøjagtige ligevægtspunkt opnås ved hjælp af kompenserende fjedre, såsom henholdsvis 31 og 25.It can be clearly seen that if these two levers had no pivot point, the guide slider could slide downward in the direction of arrow F. This movement is in fact limited because their ends respectively 36 and 32 hit the impact, the first of which is found on the the contact holder 4, which is actuated by an elastic member 9, and the other is located at the end 24 of the bellows itself and is influenced by the inner spring 32. The exact equilibrium point is obtained by compensating springs such as 31 and 25 respectively.
Resultatet af dette arrangement er, at styreglideren lo er eftergivende monteret, og svalehalen 11 har to frihedsgrader» som muliggør, at den let indstiller sig af sig selv på linie med kloen 12 på koblingstidspunktet. Denne kobling opnås ved en relativ bevægelse af de to huse 1 og 14, som er vinkelret på figurens plan.The result of this arrangement is that the guide slider 1o is resiliently mounted, and the dovetail 11 has two degrees of freedom, which allow it to readily align itself with the claw 12 at the time of coupling. This coupling is obtained by a relative movement of the two housings 1 and 14 which are perpendicular to the plane of the figure.
En lås 27, der er svingeligt lejret på huset ved hjælp af en tap 28, og som er påvirket af en fjeder 26, har en læbe 3o, der 4 143672 er indrettet til at samvirke med en rand 8 ud i et med kontaktholderen. I den i fig. 1 viste stilling er låsen inaktiv, og dens ende 29 hviler mod det nederste af bælgen.A lock 27 pivotally mounted on the housing by means of a pin 28 and actuated by a spring 26 has a lip 30 which is adapted to cooperate with a rim 8 integrally with the contact holder. In the embodiment shown in FIG. 1, the lock is inactive and its end 29 rests on the bottom of the bellows.
En betjeningstrykknap 33, som rager ud fra huset i nærheden af indstillingsknappen 3, er forlænget nedad med et stop 35, som rager lidt ud fra den nederste overflade. En returfjeder 34 søger med et lille tryk at presse en del af dette stop imod det nederste af armen 16 på styreglideren lo. Det fremgår ligeledes af fig. 3, at de forskellige vægtstænger og bevægelige dele er anbragt i forskellige lodrette planer. Medens fig. 3 for tydelighedens skyld viser omdrejningstappene eller leddene 17,18,21,22 og 28 i forskellige planer, er disse i virkeligheden anbragt i det væsentlige i samme plan svarende til det i fig. 3 viste.An operating pushbutton 33 projecting from the housing in the vicinity of the adjustment knob 3 is extended downwardly with a stop 35 projecting slightly from the lower surface. A return spring 34, with a small pressure, seeks to push a portion of this stop against the bottom of the arm 16 of the guide slide 1o. It can also be seen from FIG. 3 shows that the different levers and moving parts are arranged in different vertical planes. While FIG. 3, for the sake of clarity, shows the pivots or joints 17,18,21,22 and 28 in different planes, in fact these are arranged substantially in the same plane similar to that of FIG. 3.
Resultatet af dette arrangement er, at rummet omkring de forskellige bevægelige dele er stort og følgelig tillader betydeligt spillerum, som letter valget af en indstillingsposition for svalehalen 11. Det vil også ses, at bælgen 2's nederste del 24's nærhed medfører særlige foranstaltninger for kontaktholderen 4, der skal forblive tæt ved vægtstangen 19. En elegant løsning er blevet fundet ved at give denne kontaktholder 4 form som en ring, som bælgen kan gå igennem.The result of this arrangement is that the space around the various moving parts is large and consequently allows considerable leeway which facilitates the selection of a setting position for the dovetail 11. It will also be seen that the proximity of the lower part 24 of the bellows results in special measures for the contact holder 4. which must remain close to the lever 19. An elegant solution has been found by giving this contact holder 4 the shape of a ring through which the bellows can pass.
Denne ring er svingeligt anbragt ved hjælp af to lejer 5,5', der ligger diametralt modsat hinanden og følgelig giver udmærket styring for kontaktholderen 4. Kontakterne, som bæres af ringen, er vist ved 6 og 7 og er også anbragt ved enderne af en diameter af ringen, hvilket sikrer god ligevægt af kontaktholderen og giver kontakterne en stor vandring for en bestemt drejning.This ring is pivotally arranged by two bearings 5,5 'which are diametrically opposed to each other and consequently provide excellent control for the contact holder 4. The contacts carried by the ring are shown at 6 and 7 and are also arranged at the ends of a diameter of the ring, which ensures good balance of the contact holder and gives the contacts a large migration for a particular rotation.
Hvis kun en af kontakterne 6 eller 7 var nødvendig, kunne kontaktholderen 4 blot have form som en gaffel, hvis ender kunne bære omdrejningstappe.If only one of the contacts 6 or 7 was needed, the contact holder 4 could simply be shaped like a fork whose ends could carry pivots.
Under drift trækkes den bevægelige glider i retning af pilen F som vist i fig. 2.In operation, the movable slide is pulled in the direction of arrow F as shown in FIG. 2nd
I denne stilling har enden 23 af vægtstangen 2o sammentrykket bælgen mod virkningen af den indre fjeder 32. På den anden side har den opadgående bevægelse af enden 36 af vægtstangen 19 bevirket, at kontaktholderen 4 vipper, hvorved på den ene side kontakterne 6 og 7 omskiftes, og fjederen 9 sammentrykkes, og på den anden side randen 8 sammenlåses med læben 3o på låsen 27.In this position, the end 23 of the lever 20 has compressed the bellows against the action of the inner spring 32. On the other hand, the upward movement of the end 36 of the lever 19 causes the contact holder 4 to tilt, thereby switching contacts 6 and 7 on one side. and the spring 9 is compressed and, on the other hand, the rim 8 is interlocked with the lip 3o of the lock 27.

Denne stilling svarer til den aktive stilling af kontaktholderen. Når kontaktoren 14 deaktiveres, går styreglideren lo straks tilbage til sin stilling i fig. 1, men det tager nogen tid for den nederste del 24 af bælgen at genantage sin hvilestilling.This position corresponds to the active position of the contact holder. When the contactor 14 is deactivated, the control slider lo immediately returns to its position in FIG. 1, but it takes some time for the lower part 24 of the bellows to resume its resting position.
Under sin nedadrettede vandring rammer den armen 29 i låsen og frigiver således kontaktholderen under indvirkning af fjederen. Kontakterne 6 og 7 bliver således omskiftet med nogen forsinkelse.During its downward travel, it strikes the arm 29 in the lock, thus releasing the contact holder under the action of the spring. Thus, contacts 6 and 7 are switched with some delay.
Ved betragtning af fig. 1 vil det ses, at når huset 1 sættes på plads på huset 14, vil dette bevirke, at stoppet 35 kommer i kontakt med en støtteflade 37 på den bevægelige komponent 13 i kontaktoren. Dette stop er anbragt således, at det rager lidt igennem, så at dets bevægelse, når det trykkes tilbage, bevirker en lille op-adrettet bevægelse af svalehalen 11, som før sammenkoblingen af de to enheder kunne være bragt ud af indstilling på linie med kloen 12. Denne bevægelse er tilstrækkelig til at muliggøre, at denne indstilling på linie nu opnås uden vanskelighed.In view of FIG. 1, it will be seen that when the housing 1 is inserted into the housing 14, this will cause the stop 35 to contact a support surface 37 of the moving component 13 in the contactor. This stop is arranged so that it protrudes slightly so that its movement, when pushed back, causes a small upward movement of the dovetail 11, which before the coupling of the two units could be brought out of alignment with the claw 12. This movement is sufficient to enable this alignment to be achieved now without difficulty.
Det vil forstås, at trykknappen 33 gør det muligt at simulere kontaktorens funktion. Da den endvidere ikke er forbundet med styreglideren i retning af pilen F, kan dens påvirkning ikke bringe koblingen 12 og 11 ud af indstilling på linie med hinanden.It will be appreciated that the pushbutton 33 makes it possible to simulate the function of the contactor. Furthermore, since it is not connected to the control slider in the direction of arrow F, its influence cannot align coupling 12 and 11 out of alignment.
I det i fig. 4 viste apparat er trykstangen 42 med koblingssvalehalen 11 styret lodret med spillerum under forskydningen og har to fremspring 4o og 41. Det første af disse fremspring tjener til at omstille kontaktholderen, og det andet til at omstille tidsafbryderen, når kontaktoren deaktiveres. Når kontaktoren aktiveres, udvider bælgen sig og bevirker som i det foregående tilfælde, at låsen 27 åbnes og således frigiver kontaktholderen. Den samme kontaktholder 4, som blev anvendt i det foregående eksempel, anvendes her med de samme fordele.In the embodiment of FIG. 4, the push rod 42 with the coupling dovetail 11 is controlled vertically with clearance during the displacement and has two projections 4o and 41. The first of these projections serves to switch the contact holder and the second to switch the time switch when the contactor is deactivated. When the contactor is activated, the bellows expands and, as in the previous case, opens the lock 27 and thus releases the contact holder. The same contact holder 4 used in the previous example is used here with the same advantages.
