Description

[0001] A presente invengao refere-se a um conjunto de rele multipolar de acordo com o preambulo da reivindicapao 1.[0001] The present invention relates to a multipolar relay assembly according to the preamble of claim 1.

[0002] Um conjunto de rele multipolar desta especie passou a ser conhecido, por exemplo, pelo documento DE 10 2007 029 633 A1.[0002] A set of multipolar relays of this kind became known, for example, by document DE 10 2007 029 633 A1.

[0003] Neste conhecido conjunto de rele, dois reles de construpao identica estao dispostos sequencialmente em uma carreira e que apresentam molas de lamina como elementos comutadores que sao ativadas em sincronismo por um acionamento magnetico conjunto integrado. Os contatos de acoplamento de um rele estao dispostos em carreira depois dos contatos acopladores do outro rele, sendo angulares em sentido retangular para com o piano das molas de lamina. Com esses contatos acopladores, retangulares em relapao as molas de lamina, no caso de uma corrente de curto circuito em um rele, o campo magnetico entao formado nao exercera efeito sobre o outro rele.[0003] In this well-known set of relays, two relays of identical construction are arranged sequentially in a row and which present leaf springs as switching elements that are activated in synchronism by an integrated magnetic drive. The coupling contacts of one relay are arranged in rows after the coupling contacts of the other relay, being angled in a rectangular direction towards the piano of the leaf springs. With these coupling contacts, rectangular in relation to the leaf springs, in the case of a short circuit current in a relay, the magnetic field then formed will have no effect on the other relay.

[0004] Todavia, para alguns empregos e desejavel que os contatos acopladores nao sejam angulares em sentido retangular em relapao as molas de lamina, porem, por exemplo, se estendam em paralelo para com as molas de lamina. Na eventualidade de uma corrente de curto circuito em um rele podera entao, todavia, o campo magnetico que se apresentara ao redor dos acopladores deste rele produzir uma atrapao ou uma repulsao da mola de lamina do outro rele, resultando, por conseguinte em funpao falha do rele.[0004] However, for some jobs it is desirable that the coupling contacts are not angled in a rectangular direction in relation to the leaf springs, but, for example, extend in parallel to the leaf springs. In the event of a short circuit current in a relay, however, the magnetic field that will appear around the couplers of this relay will produce a trap or a repulsion of the leaf spring of the other relay, therefore resulting in failure of the relay.

[0005] Constitui objetivo de presente invenpao ampliar um conjunto de rele da especie especialmente citada no sentido de que estas funpoes falhas estejam excluidas.[0005] The objective of the present invention is to expand a set of relays of the species specifically cited in the sense that these faulty functions are excluded.

[0006] De acordo com a invenpao, esta tarefa sera solucionada por um conjunto de rele multipolar de acordo com a reivindicapao 1.[0006] According to the invention, this task will be solved by a set of multipolar relays according to claim 1.

[0007] De acordo com a invenpao os contatos acopladores dos reles disposto em sequencia estao reciprocamente encaixados por rele, sendo que, o contato de um rele situado internamente e voltado na diregao de um rele adjacente, apresenta, atraves do contato de conexao, um contato acoplador externo. Uma corrente de curto circuito que no caso incidente flui no contato de conexao produz um campo magnetico ao redor do contato acoplador mais que nao exerce forga sobre as molas de contato que pudesse produzir uma suspensao eletromagnetica das molas de contato.[0007] According to the invention the coupling contacts of the relays arranged in sequence are reciprocally connected by relay, and the contact of a relay located internally and facing towards an adjacent relay, presents, through the connection contact, a external coupler contact. A short circuit current that in the incident case flows in the connection contact produces a magnetic field around the coupling contact, which does not exert any force on the contact springs that could produce an electromagnetic suspension of the contact springs.

[0008] O conceito de acordo com a invengao podera ser transferido tambem para conjunto de reles de polaridade mais alta, sendo que, cada outro rele apresenta sobre outro contato de conexao com um contato de conexao situado externamente.[0008] The concept according to the invention can also be transferred to a set of higher polarity relays, with each other relay presenting another connection contact with an externally located connection contact.

Da mesma maneira, as caractensticas acima mencionadas e que ainda serao citadas posteriormente, podem ser empregados cada qual independentemente ou em conjunto, em combinagbes aleatorias. As modalidades mostradas e descritas nao devem ser entendidas como uma relagao final, mas possui um carater exemplificado para a explanagao da invengao.[0009] Other advantages and advantageous modalities of the object of the invention can be inferred from the description, design and claims. In the same way, the characteristics mentioned above and which will still be mentioned later, can each be used independently or together, in random combinations.

[0012] Figuras 2a, 2b vista lateral dianteira em perspectiva (fig. 2a) e um conjunto de rele de tres polos de acordo com a invengao, bem como o conjunto de contatos de rele pertencentes (fig. 2b).[0012] Figures 2a, 2b front side view in perspective (fig. 2a) and a set of three pole relays according to the invention, as well as the set of relay contacts belonging to it (fig. 2b).

[0013] O conjunto de rele 1 de dois polos, apresentado na fig. 1, abrange dois reles 2i, 22 de identica construgao e um polo e um acionamento magnetico comum 8.[0013] The two pole relay set 1, shown in fig. 1, comprises two relays 2i, 22 of identical construction and a pole and a common magnetic drive 8.

[0014] Cada um dos dois reles 2i, 22 apresenta dois contatos de rele 3i, 4% ou seja, 32, 42 e uma mola de contatos 5 que fecha ou interrompe o circuito de corrente entre os dois contatos de rele, sendo que, a referida mola e conformada como mola de lamina ou mola chata condutora de eletricidade. Uma extremidade da mola de contato 5 esta presa conduzindo eletricidade, no contato de rele esquerdo na fig. 1a, 3i, 32, ao passo que a outra extremidade 6 livre possui um botao de contato 7, podendo ser desativada atraves do acionamento magnetico comum 8. As molas de contato 5 dos dois reles 2i, 22, na posigao de rele mostrada fechada, estao de tai modo desviados para o lado direito e os seus botoes de contato 7 encostam em um botao de contato 9 do contato de rele direito 4i, 42, e na posigao de rele aberta (nao mostrada), sao de tai modo desviados para o lado esquerdo que os seus botoes de contato 7 estao suspenses do botao de contato 9 do contato de rele direito 4i, 42[0014] Each of the two relays 2i, 22 has two relay contacts 3i, 4% ie 32, 42 and a contact spring 5 that closes or interrupts the current circuit between the two relay contacts, said spring is formed as a leaf spring or flat electrically conductive spring. One end of the contact spring 5 is attached conducting electricity to the left relay contact in fig. 1a, 3i, 32, while the other free end 6 has a contact button 7, which can be deactivated through the common magnetic drive 8. The contact springs 5 of the two relays 2i, 22, in the position of the relay shown closed, they are so deviated to the right side and their contact buttons 7 touch a contact button 9 of the right relay contact 4i, 42, and in the open relay position (not shown), they are so deviated to the left side that your contact buttons 7 are suspended from contact button 9 of the right relay contact 4i, 42

[0015] O acionamento magnetico 8 abrange uma bobina magnetica 10 que pode ser repolarizada como um circuito magnetico em cujos os dois flancos de jugo 11 esta mantido giravel induzido (bascula de induzido) 12 ou ima permanente (nao mostrado). O ima permanente esta integrado entre duas placas de induzido 13 que encostam-se as duas posigoes terminals de comutagao do induzido 12 nos respectivos flancos jugo 11. A bobina magnetica 10 e o induzido 12, giravel entre as suas duas posigoes terminals de comutagao, constituem uma atragao de induzido H. Com o seu brago 14 saliente, o induzido 12 penetre em uma abertura 15 (fig. 1d) de um cursor 16 que esta previsto linearmente deslocavel (seta dupla 17) na diregao de deflexao das molas de contatos 5, ou seja, em paralelo para com o eixo da bobina magnetica 10. O movimento giratorio do induzido 12 resulta, portanto, em um movimento linear do cursor 16. A livre extremidade 6 e as molas de contato 5 encaixam entre duas saliencias 18, 19 do cursor 16. Se o cursor 16 for deslocado para o lado direito, arrastara com sua saliencia esquerda 18 a mola de contato 5 na diregao de fechamento do rele, ou seja, para o lado direito, ate a posipao de rele fechada. Se o cursor 5 for deslocado para o lado esquerdo entao arrastara com sua saliencia 18 direita a mola de contato 5 na direpao da abertura de rele, isto e, para o lado esquerdo ate a posipao de rele aberto. Em outras palavras, as duas molas de contatos 5 estao acoplados em sua movimentapao em sincronismo com o cursor 16 na direpao de abertura e fechamento dos dois reles 2i, 22. Nas livres extremidades 6 das molas de contatos 5 esta presa uma mola de lamina 20 de apo para lamina cuja a livre extremidade esta presa na saliencia esquerda 18 do cursor 16.[0015] The magnetic drive 8 comprises a magnetic coil 10 that can be repolarized as a magnetic circuit in which the two yoke flanks 11 are maintained rotatable induced (armature tip) 12 or permanent magnet (not shown). The permanent magnet is integrated between two armature plates 13 that rest against the two terminal switching positions of armature 12 on the respective flanks yoke 11. Magnetic coil 10 and armature 12, rotatable between their two terminal switching positions, constitute an armature attraction H. With its protruding cylinder 14, the armature 12 penetrates an opening 15 (fig. 1d) of a slider 16 which is provided linearly displaceable (double arrow 17) in the direction of deflection of the contact springs 5, that is, in parallel with the axis of the magnetic coil 10. The rotating movement of the armature 12 results, therefore, in a linear movement of the cursor 16. The free end 6 and the contact springs 5 fit between two projections 18, 19 of the cursor 16. If the cursor 16 is moved to the right side, it will drag with the left protrusion 18 the contact spring 5 in the direction of closing the relay, that is, to the right side, until the position of the relay closed. If the cursor 5 is moved to the left side then it will drag the contact spring 5 with its right protrusion 18 towards the relay opening, that is, towards the left side until the position of the open relay. In other words, the two contact springs 5 are coupled in their movement in synchronism with the cursor 16 in the direction of opening and closing the two relays 2i, 22. At the free ends 6 of the contact springs 5 a leaf spring 20 is attached support for blade whose free end is attached to the left protrusion 18 of the cursor 16.

[0016] Os dois reles 2i, 22 estao dispostos sequencialmente em uma carreira na direpao de flexao das suas molas de contatos 5, ou seja, na direpao da movimentapao 17 do cursor 16, sendo que o acionamento magnetico 8 completo, isto e, a bobina magnetica 10 e o induzido 12, estao dispostos na direpao de deslocamento 17 do cursor 16 ao lado dos dois reles 2i, 22.[0016] The two relays 2i, 22 are arranged sequentially in a row in the direction of flexion of their contact springs 5, that is, in the direction of the movement 17 of the cursor 16, the magnetic drive 8 being complete, that is, the Magnetic coil 10 and armature 12 are arranged in the direction of travel 17 of the cursor 16 next to the two relays 2i, 22.

[0017] Para comutapao do conjunto de rele 1, o campo magnetico da bobina magnetica 10 sera repolarizado, com o que, o induzido 12 sera girado e o cursor 16 sera deslocado. Na posipao de rele fechado, mostrado na fig. 1a, o cursor 16 e deslocado para o lado direito atraves do brapo 14 girado no sentido dos ponteiros do relogio, com o que, atraves da saliencia 18 esquerda tambem as molas de contato 5 sao desviadas em sincronismo para o lado direito ate encostarem os seus botdes de contato 7 nos botoes de contato 9 dos contatos de rele direitos 4i, 42. A pressao de compressao dos botoes de contato 7 contra os botoes de contato 9 dos contatos de rele diretos 4i, 42 e proporcionada pela forpa de pressao das molas de contato 20 comprimidas pelo cursor 15 na posipao de rele fechada, as molas de contato 20 reagem a deflexao das molas de contato 5 na direpao de abertura, o que resulta em um fechamento redutor de choque dos dois reles 2i, 22. Pela repolarizapao da bobina magnetica 10 o induzido 12 sera girado no sentido dos ponteiros do relogio e desta maneira o cursor 16 sera deslocado para o lado esquerdo, com o que, as molas de contato 5 sao arrastadas pelas saliencias direitas 19 do cursor 16 na direpao da abertura e os botoes de contatos 7 serao suspenses em sincronismo dos botoes de contato 9 dos contatos de rele direitos 4i, 42.[0017] For switching of the relay assembly 1, the magnetic field of the magnetic coil 10 will be repolarized, whereby the armature 12 will be rotated and the cursor 16 will be moved. In the closed relay position shown in fig. 1a, the cursor 16 is moved to the right side by means of the arm 14 turned in the direction of the clock hands, whereby, through the projection 18 on the left, also the contact springs 5 are shifted in synchronism towards the right side until they touch their contact buttons 7 on the contact buttons 9 of the right relay contacts 4i, 42. The compression pressure of the contact buttons 7 against the contact buttons 9 of the direct relay contacts 4i, 42 is provided by the pressure spring of the contact springs contact 20 compressed by the cursor 15 in the closed relay position, the contact springs 20 react to the deflection of the contact springs 5 in the opening direction, resulting in a shock reducing closing of the two relays 2i, 22. By repolarization of the coil magnetic 10 the armature 12 will be rotated clockwise and thus the cursor 16 will be moved to the left side, with which the contact springs 5 are dragged by the right projections 19 of the cursor 16 in the direction of the opening and the contact buttons 7 will be suspended in synchronization from the contact buttons 9 of the right relay contacts 4i, 42.

[0018] Os contatos dos dois reles se salientam como contatos acopladores no lado do alojamento voltado na direCAO das livres extremidades 6 das molas de contato 5, sendo que, os contatos acopladores 211, 22i dos reles de contato 3i, 4i do rele direito 2i estao dispostos entre os contatos acopladores 212, 222 dos contatos de rele 82, 42 do rele esquerdo 22. Para tanto o contato acoplador direito 22 do rele esquerdo 22, atraves de um contato de conexao 23 traseiro, em forma de uma alpa, que se estende transversalmente, ou seja, em sentido retangular para com as molas de contato 5 do rele, passando ao longo do primeiro rele 2i, esta unido com seu contato de rele 42 pertencente. Conforme mostrado na fig. 1, o contato de conexao 23 pode ser conformado como uma chapa de conexao que encosta externamente no lado traseiro do alojamento 24. Os contatos acopladores 211, 212, 22I,222 projetam-se em paralelo, ou seja, quase em paralelo bem como em sentido convergente como tambem na direpao das molas de contato 5. Para que os contatos acopladores 211, 212, 22i, 222 estejam dispostos em um quadro de acoplamento desejado, 0 contato acoplador direito 2i do rele direito 2i apresenta formapao angular em relapao aos seus contatos de rele 3i, ainda de modo correspondente com uma defasagem paralela para o lado direito.[0018] The contacts of the two relays stand out as coupling contacts on the side of the housing facing the free ends 6 of the contact springs 5, and the coupling contacts 211, 22i of the contact relays 3i, 4i of the right relay 2i are arranged between the coupling contacts 212, 222 of the relay contacts 82, 42 of the left relay 22. For this purpose, the right coupler contact 22 of the left relay 22, through a rear connection contact 23, in the form of a loop, which it extends transversely, that is, in a rectangular direction towards the contact springs 5 of the relay, passing along the first relay 2i, this is connected with its relay contact 42 belonging. As shown in fig. 1, the connection contact 23 can be formed as a connection plate that abuts externally on the rear side of the housing 24. The coupling contacts 211, 212, 22I, 222 project in parallel, that is, almost in parallel as well as in converging direction as well as in the direction of the contact springs 5. For the coupling contacts 211, 212, 22i, 222 to be arranged in a desired coupling frame, the right coupling contact 2i of the right relay 2i has angled formation in relation to its contacts relay 3i, still correspondingly with a parallel offset to the right side.

[0019] Um encaixe desta especie dos contatos acopladores internos (condutor zero) 211, 22i entre os contatos acopladores externo IN e OUT 212, 222 results em um padrao acoplador "simetrico". Desta maneira sera viabilizado o desligamento bipolar de um percurso de corrente sem quaisquer efeitos no caso de correntes de curto circuito. Ocorre que uma corrente de curto circuito que flui dentro do contato de conexao 23 e produz um campo magnetico ao redor do contato de conexao 23, mas que nao exerce forga sobre as molas de contato 5 e que pudesse produzir uma suspensao eletromagnetica das molas de contato 5.[0019] A fitting of this kind of internal coupling contacts (zero conductor) 211, 22i between the external coupling contacts IN and OUT 212, 222 results in a "symmetrical" coupling pattern. In this way it will be possible to bipolar disconnect a current path without any effects in the case of short circuit currents. It happens that a short circuit current that flows inside the connection contact 23 and produces a magnetic field around the connection contact 23, but that does not exert force on the contact springs 5 and that could produce an electromagnetic suspension of the contact springs 5.

[0020] A fig. 1d mostra o jogo de contatos do rele 25 eletricos completes do conjunto de rele 1, ou seja, os dois reles 2i, 22 com os contatos de rele 3i, 32, 4i, 42, as molas de contato 5 e os contatos acopladores 211, 212, 22i, 222 do contato de conexao 23 bem como o cursor 16. O contato de rele 4i com seu contato acoplador angular 22% bem como o contato de rele 42 com seus contatos acopladores e de conexao angulares 22i, 23 podem ser curvados inteirigos numa tira de metal (por exemplo, de cobre).[0020] FIG. 1d shows the set of contacts of the complete electric relay 25 of the relay set 1, that is, the two relays 2i, 22 with the relay contacts 3i, 32, 4i, 42, the contact springs 5 and the coupling contacts 211, 212, 22i, 222 of the connection contact 23 as well as the cursor 16. The relay contact 4i with its angular coupling contact 22% as well as the relay contact 42 with its coupling and angular connection contacts 22i, 23 can be bent in one piece on a metal strip (for example, copper).

[0021] O conceito mostrado na fig. 1 no exemplo de conjunto de rele de dois polos pode tambem ser empregado conjuntos de reles de maior numero de polos. Assim, a fig. 2a apresenta um conjunto de rele 31 de tres polos que se diferencia da fig. 1 por outro rele 23 esquerdo, disposto em carreira. Os contatos acopladores 212, 222 dos contatos de rele 32, 42 do rele 22 central estao dispostos entre os contatos acopladores 213, 223 dos contatos de rele 32,42 do rele esquerdo 23. Para tanto, o contato acoplador direito 22s do rele esquerdo 23 esta unido com seu contato de rele 4s pertencente atraves de um contato de conexao 33 adicional traseiro, em forma de alga que se estende transversalmente para com as molas de contatos 5 dos reles e que passa ao longo dos reles 22, 2i central e direito. Os dois contatos de conexao traseiros 23, 33 se estendem paralelamente distanciados e convergentes, sendo que, o contato de conexao mais longo 33 ultrapassar o contato de conexao mais curto 23 nos dois lados (fig. 2b).[0021] The concept shown in fig. 1, in the example of a two pole relay set, relay sets of larger number of poles can also be used. Thus, fig. 2a shows a set of three-pole relay 31 which differs from fig. 1 for another relay 23 on the left, arranged in a career. Coupling contacts 212, 222 of relay contacts 32, 42 of central relay 22 are arranged between coupling contacts 213, 223 of relay contacts 32,42 of left relay 23. Therefore, the right coupling contact 22s of left relay 23 it is connected with its relay contact 4s via an additional rear connection contact 33, in the form of algae which extends transversely to the contact springs 5 of the relays and which passes along the relays 22, 2i central and right. The two rear connection contacts 23, 33 extend parallel apart and converge, with the longest connection contact 33 exceeding the shortest connection contact 23 on both sides (fig. 2b).

[0022] A fig. 2b apresenta o conjunto de contatos de rele 35 eletricos do conjunto de rele 31, ou seja, os tres rales 2i, 22, 2a com os contatos de rale 3i, 32, 3a, 4i, 42, 4a, as molas de contato 5 e os contatos acopladores 211, 212, 213, 22i, 222, 22a, os contatos de conexao 23, 33 bem como o cursor 16.[0022] FIG. 2b shows the set of electric relay contacts 35 of the relay set 31, that is, the three rallies 2i, 22, 2a with the grating contacts 3i, 32, 3a, 4i, 42, 4a, the contact springs 5 and the coupling contacts 211, 212, 213, 22i, 222, 22a, the connection contacts 23, 33 as well as the cursor 16.
