Description

Predmet izuma je bistabilno stikalo z bistabilnim mehanizmom, pri katerem mehanizem in izvedba kontaktov, ki omogočata delovanje osnovne funkcije bistabilnega stikala, to je preklapljanje kontaktov s pomočjo elektromagnetnega pogona, ki je vzbujen z električnimi impulzi, omogoča preklapljanje stikala z minimalnim vložkom energije. Predloženi izum sodi v razred H01H 51/08 mednarodne patentne klasifikacije.The subject of the invention is a bistable switch with a bistable mechanism, in which the mechanism and implementation of the contacts, which enable the basic function of the bistable switch, that is, switching of contacts by means of electromagnetic actuator, excited by electrical impulses, enables switching of the switch with a minimal input of energy. The present invention falls within the class H01H 51/08 of the international patent classification.

Tehnični problem, ki ga zadovoljivo rešuje predložena izvedba bistabilnega stikala je takšna konstrukcija stikala in njegovega mehanizma, ki omogoča porabo čim manjše energije za preklop, polega tega pa je is zgrajena na preprost in cenovno ugoden način.The technical problem that is satisfactorily solved by the proposed implementation of the bistable switch is the design of the switch and its mechanism, which enables the use of as little switching energy as possible, and is also constructed in a simple and affordable manner.

Znane rešitve se poslužujejo različnih tehnik oz. fizikalnih principov delovanja mehanizma stikala. Mehanizem stikala s pomočjo zobatega kolesa po patentnem dokumentu EP 1024511 ne omogoča preklapljanja večjih bremen, saj bi sile potrebne za preklop povzročile preveč trenja.Known solutions use different techniques or techniques. the physical operating principles of the switch mechanism. The gear mechanism of the gear wheel according to patent document EP 1024511 does not allow the switching of large loads, since the forces required to switch would cause too much friction.

Druga rešitev je mehanizem stikala na principu sidrišča v obliki srca po patentnem dokumentu WO0186682 in EP1901327. Slabost te rešitve je, da je izklop na drugo fronto oz. stikalo izklopi šele potem, ko tuljavi odvzamemo napetost oz. sprostimo gumb, če stikalo preklapljamo ročno.Another solution is the heart-shaped anchor switch mechanism according to patent document WO0186682 and EP1901327. The disadvantage of this solution is that switching off to a different front or. the switch is switched off only after the coils have been removed. release the button if the switch is manually switched.

Mehanizem s pomočjo zibelke po patentu EP0641000 in EP0641003 ne vključuje preklapljanja kontaktov s kontaktnim mostičkom.The cradle mechanism according to patent EP0641000 and EP0641003 does not include switching contacts with the contact bridge.

Bistabilno stikalo z bistabilnim mehanizmom po izumu rešuje zahteve po energetsko varčnem mehanizmu, ki istočasno omogoča stikanje kontaktov namenjenim večjim bremenom na tak način, da je vzmet zibelke 6 vpeta na vzvod 1 in na zibelko 3, na njo pa sta simetrično na os vrtenja zibelke 3, vpeta tudi mostička 4 in 5.A bistable switch with a bistable mechanism according to the invention solves the requirements of an energy-saving mechanism, which simultaneously enables the contacting of contacts intended for larger loads in such a way that the cradle 6 spring is clamped to the lever 1 and the cradle 3 and symmetrically to the axis of rotation of the cradle 3 , also bridges 4 and 5.

Bistabilno stikalo z bistabilnim mehanizmom po izumu tvorijo zibelka 3, ki je sredinsko uležajena v ohišju stikala in ima čep 11 na katerega je vpeta vzmet 6 zibelke 3. Vzvod 1 je uležajen v ohišju in s čepom 19 prebada podolgovati utor v zibelki 3. Vzvod 1 služi kot signalizator pozicije, gumb za ročno stikanje kontaktov 13,15 in nosilec vpetja vzmeti 6 zibelke 3. Vpetje vzmeti 6 je izvedeno s čepom 7 za izvedbe z enim odpiralnim in enim zapiralnim kontaktom in s čepom 8 za izvedbe z dvema zapiralnima kontaktoma. Na ta način je optimirana potrebna sila za stikanje kontaktov io oz. stiskanje kontaktnih vzmeti. Mostiček 5, ki služi kot nosilec odpiralnega kontaktnega mostička 14 in kontaktne vzmeti 18 je vpet s podolgovatim utorom na čep 12, ki je na zibelki 3 postavljen simetrično na os vrtenja zibelke 3 glede na čep 10 na katerega je vpet mostiček 4, ki služi kot nosilec zapiralnega kontaktnega mostička 13 in kontaktne vzmeti 17. S takim načinom vpetja je racionalizirano število potrebnih fiksnih kontaktov 16, 15. V primeru izvedbe z dvema zapiralnima kontaktoma pa sta na zibelko 3 vpeta dva mostička 4 in sicer na čep 10 in na drugi strani zibelke na čep 20, ki se nahaja na enaki poziciji.A bistable switch with a bistable mechanism according to the invention is formed by a cradle 3, which is centrally mounted in the switch housing and has a pin 11 to which a spring 6 of the cradle is attached. Lever 1 is supported in the housing and with a pin 19 pierces the elongated groove in the cradle 3. Lever 1 serves as a position indicator, button for manually contacting contacts 13.15 and spring holder of cradle 6 of cradle 3. Spring mounting 6 is made with pin 7 for designs with one opening and one closing contact and with pin 8 for versions with two closing contacts. In this way, the required force for contacting io and / or contacts is optimized. compression of contact springs. The bridge 5, which serves as a support for the opening contact bridge 14 and the contact springs 18, is clamped with an elongated groove to the pin 12, which is positioned symmetrically on the cradle 3 on the axis of rotation of the cradle 3 relative to the pin 10, to which the bridge 4 is used, which serves as the holder of the closing contact bridge 13 and the contact springs 17. With this method of clamping, the number of required fixed contacts 16, 15 is rationalized. In the case of a design with two closing contacts, two jumps 4 are mounted on the cradle 3, on the plug 10 and on the other side of the cradle. to pin 20, which is in the same position.

Preklopno energijo zagotavlja elektromagnet katerega sestavni del je kotva 9. Kotva 9 pritiska na potiskač 2 ta pa silo prenese na zibelko 3, ki linearno gibanje potiskača 2 pretvori v moment, ki preko čepov 10, 20 in 12 premika mostička 4 in 5.The switching energy is provided by an electromagnet of which component 9. Anchor 9 presses on the pusher 2, which then transfers the force to the cradle 3, which converts the linear motion of the pusher 2 into a moment, which moves pins 4 and 5 through pins 10, 20 and 12.

Bistabilno stikalo po izumu lahko preklapljamo tudi ročno. V tem primeru delujemo na vzvod 1 ki oscilira okrog uležajenja v ohišju in preko čepa 19 poganja zibelko 3, ta pa potem preko čepov 10,20 in 12 premika mostička 4 in 5.The bistable switch according to the invention can also be manually switched. In this case, we operate on a lever 1 which oscillates around the bearing in the housing and drives the cradle 3 through the stud 19, which then moves the jumper 4 and 5 through the studs 10,20 and 12.
