Poistú jednotku takéhoto spínača tvorí napríklad tavná poistka a slúži na to, aby pomocou spínača prerušila prúdový obvod, keď inzenzita prúdu prekročí prípustnú hodnotu. Známe spínače tohto druhu majú poistnú jednotku z poistkovej vložky, vytvorenej ako patróna a opatrenú na svojich protiľahlých koncoch elektrickými kontaktmi, a príslušný držiak. Pri výmene poistky sa nová poistková vložka vloží do držiaku a potom sa pomocou držiaku nasadí do telesa spínača tak, že sú jej elektrické kontakty zovreto držané medzi kontaktmi spínača. Pritom môže dôjsť, pokial sa poistná jednotka vloží do telesa nesprávne, na chybnú funkciu.The fuse unit of such a switch is formed, for example, by a fuse and serves to interrupt the circuit by means of a switch when the current insensitivity exceeds the permissible value. Known switches of this kind have a fuse unit made of a fuse-link formed as a cartridge and provided with electrical contacts at their opposite ends and a corresponding holder. When replacing the fuse, the new fuse-link is inserted into the holder and then inserted into the switch body by means of the holder so that its electrical contacts are clamped between the switch contacts. This can lead to malfunction if the safety unit is inserted incorrectly in the housing.
Úlohou vynálezu je zlepšenie funkčnej bezpečnosti takéhoto spínača.The object of the invention is to improve the functional safety of such a switch.
Podstata vynálezuSUMMARY OF THE INVENTION

Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Spínač má teleso 10 z elektricky izolujúceho plastu, ktoré je vytvorené známym spôsobom ako teleso na upevnenie na upínaciu lišu a k tomuto účelu má na svojom, na výkrese spodnom okraji zaskakovací mechanizmus 12 na zaskočenie na neznázornenú upínaciu lištu poistnej a rozdelovacej skrine apod. Káblové svorky 14 a 16 na protiľahlých koncoch telesa 10, medzi ktorými sda môže pomocou spínača vytvoriť a prerušiť elektrický kontakt, slúžia na svorkové upevnenie neznázorneného pripojovacieho kábla.The switch has a body 10 of electrically insulating plastic, which is formed in a known manner as a body for fastening to a clamping bar and, for this purpose, has at its lower edge a snap-on mechanism 12 for snapping onto a clamping bar (not shown). The cable terminals 14 and 16 at the opposite ends of the body 10, between which the electrical contact can be established and interrupted by means of a switch, serve to clamp the connection cable (not shown).
Spínacia páka 18 je uložená v telese 10 otáčavo okolo osi 20 a pôsobí cez spínaciu vačku 22 a kĺbový medzičlánok 24 na spínací mostík 26, ktorý je uskutočnený presuvne medzi rebrami, vytvarovanými na telese 10. Káblová svorka 14 je elektricky spojená s kontaktným plechom 28, ktorý tvorí elektrický kontakt 30 nachádzajúci sa proti spínaciemu mostíku 26. Medzikontaktný plech 32 je v telese 10 držaný tak, že jeho koniec lícuje s kontaktným plechom 28, avšak je od neho vzdialený zreteľným medzipriestorom, a nachádza sa ďalším elektrickým kontaktom 34 proti spínaciemu mostíku 26. Kontaktný mostík 26 je predpätý tlačnou pružinou 36 v smere na kontakty 30 a 34, a však v stave znázornenom na obr.l je medzičlánkom 24 ešte držaný v odstupe od kontaktov 30 a 34, takže spínač ešte nie je zapnutý.The switch lever 18 is mounted in the body 10 rotatably about the axis 20 and acts via the switch cam 22 and the articulated link 24 on the switch bridge 26 which is displaceable between the ribs formed on the body 10. The cable clamp 14 is electrically connected to the contact plate 28. The intermediate contact plate 32 is held in the body 10 such that its end is flush with the contact plate 28 but is spaced from it by a distinct intermediate space, and is located by another electrical contact 34 opposite the switching plate 26. The contact bridge 26 is biased by a compression spring 36 in the direction of the contacts 30 and 34, but in the state shown in Fig. 1 it is still held at a distance from the contacts 30 and 34 by the intermediate member 24 so that the switch is not yet switched on.
S druhou káblovou svorkou 16 je spojený ďalší kontaktný plech .38, ktorý tvorí spoločne s medzikontaktným plechom 32 zvieracie uloženie na poistnú jednotku 40 . Poistná jednotka 40 má držiak 42, vyrobený v podstate v tvare písmena U, do ktorého je poistková vložka 44 vložitelná tak, že lektródy 4 6 a 48 na protiľahlých koncoch poistkovej vložky sú voľne prístupné.A second contact plate 38 is connected to the second cable clamp 16, which together with the intermediate contact plate 32 forms an animal fit on the locking unit 40. The fuse unit 40 has a substantially U-shaped holder 42 into which the fuse insert 44 is insertable such that the electrodes 46 and 48 at the opposite ends of the fuse insert are freely accessible.
Medzikontaktný plech 32 tvorí dosadaciu plochu pre držiak 42 ako aj protikontakt elektródy 4 6 poistkovej vložky. Voľný koniec edzikontaktného plechu 32 sa opiera cez tlačnú pružinu 50 o teleso 10 tak, že sa medzikontaktný plech pevne pritláča proti elektróde 4 6 a tým pritláča elektródu £8, nachádzajúcu sa na protilahlom konci poistkovej vložky 44, pevne proti kontaktnému plechu 38. Držiak 42 sa lahkým klopným pohybom zasúva do telesa 10 a má blízko kontaktu 48 blokovací nos '52 ktorý zaberá za rebro 54 telesa a tak zaisťuje držiak 42 v jeho polohe v telese 10. Horný koniec držiaku 42 tvorí operu 56 pre voľný koniec spínacej páky 18.The contact plate 32 forms the bearing surface for the holder 42 as well as the counter contact of the electrode 46 of the fuse-link. The free end of the pre-contact plate 32 is supported by a compression spring 50 against the body 10 such that the contact plate is firmly pressed against the electrode 46 and thereby presses the electrode 48 located at the opposite end of the fuse link 44 firmly against the contact plate 38. it slides into the body 10 with a slight tilting movement and has a locking nose 52 close to the contact 48 which engages the body rib 54 thereby securing the holder 42 in its position in the body 10. The upper end of the holder 42 forms a support 56 for the free end of the switch lever 18.
Na spínacej vačke 22, ktorá je na svojej strane spojená tuhým spôsobom so spínacou pákou 18, je na strane privrátenej na poistnú jednotku 40 vytvarovaný nos 58.. Tomuto nosu 58 je na voči nemu protiľahlej vonkajšej stene držiaku 42 priradené vybranie 60.On the switching cam 22, which is rigidly connected to the switching lever 18 on its side, a nose 58 is formed on the side facing the securing unit 40. This nose 58 has a recess 60 associated with the outer wall of the holder 42 opposite it.
Spínacia vačka 22 tvorí spoločne s tlačnou pružinou 36 úvratový mechanizmus spínacej páky 18. V stave znázornenom na obr.l sa spínacia páka 18 už otočila tak ďaleko vpravo v smere ku svojej zapnutej polohe, že spínacia vačka prekročila úvrat, a medzičlánkom 24 zaťažovaným tlačnou pružinnou 36, sa otáča ďalej v smere k zapnutej polohe.The switching cam 22 together with the compression spring 36 forms the dead center mechanism of the switching lever 18. In the state shown in FIG. 36, is rotated further in the direction towards the on position.
Na obr.2 je znázornený stav, v ktorom je spínacia páka celkom otočená do zapnutej polohy a dosadá na operu 56. V tomto stave je spínací mostík 26 držaný tlačnou pružinou 36 v dotyku s kontaktmi 30 a 34, takže káblové svorky 14 a 16 sú vzájomne elektricky spojené cez kontaktné plechey 28, 32 a 38 a poistkovú vložkuFIG. 2 shows the state in which the switch lever is completely turned to the on position and abuts the support 56. In this state, the switch bridge 26 is held by the compression spring 36 in contact with the contacts 30 and 34 so that the cable terminals 14 and 16 are interconnected electrically via contact plates 28, 32 and 38 and a fuse-link
44. Na obr. 2 je ďalej vidieť, že nos 58, spojený tuhým spôsobom so spínacou pákou 18, sa nachádza vo vybraní 60 držiaku 42 poistnej jednotky.44. In FIG. 2, the nose 58, rigidly connected to the switch lever 18, is located in the recess 60 of the retainer 42 of the locking unit.
Keď je spínacia páka 18 otočená celkom vľavo do svojej vypnutej polohy, je možné pri výmene poistky poistkovú vložku 44 pomocou držiaku 42 vybrať z telesa 10. Potom, keď bola nová poistková vložka 44 vložená do držiaku 42., sa tento držiak opäť pritlačí proti medzikontaktnému plechu 32 a svojim blokovacím nosom 52 sa zahákne za rebro 54 telesa.When the switch lever 18 is turned all the way to the left, it is possible to remove the fuse-link 44 from the housing 10 by replacing the fuse 44 by means of the holder 42. After the new fuse-link 44 has been inserted into the holder 42, it is again pressed against the contact The metal plate 32 and its locking nose 52 hook into the body rib 54.
Na obr.3 je znázornený spínač v stave, v ktorom nebol držiak 42 správne zasunutý. V tomto prípade blokovací nos 52 nezaberá za rebro 54., ale sa nestabilne opiera o koniec rebra 54 . Elektróda 4 8 poistkovej vložky 44 preto tvorí s kontaktným plechom 38 iskrovú medzeru. Pretože však v tomto stave držiak 42 zaujíma trocha šikmú polohu, nachádza sa jeho horná hrana, na obr.3 vľavo, v dráhe pohybu nosu 58 spínacej páky .18. Keď sa skúsi otočiť spínaciu páku 18 do zapnutej polohy, naráža preto nos 58 na horný okraj držiaku 42 nad vybraním 60, takže sa spínacia páka 18 ďalej neotáča a tým nepripúšťa pohyb kontaktného mostíka 26 do zapnutej polohy. Až keď sa korigovalo uloženie, môže nos 58 opäť vniknúť do vybrania 60, takže je možné spínač zapnúť.FIG. 3 shows the switch in a state in which the holder 42 has not been properly inserted. In this case, the locking nose 52 does not engage the rib 54, but unstably abuts the end of the rib 54. The electrode 48 of the fuse-link 44 therefore forms a spark gap with the contact plate 38. However, since in this state the holder 42 takes a slightly inclined position, its upper edge, on the left in FIG. 3, is in the path of movement of the nose 58 of the switching lever 18. Therefore, when attempting to rotate the switch lever 18 to the on position, the nose 58 impinges on the upper edge of the holder 42 above the recess 60, so that the switch lever 18 no longer rotates and thereby does not allow the contact bridge 26 to move to the on position. Only when the fit has been corrected can the nose 58 again enter the recess 60 so that the switch can be turned on.
