Področje tehnike, v katero spada izumFIELD OF THE INVENTION

Izum se nanaša na električno grebenasto stikalo s telesom stikala in stikalnim valjem, ki nosi več stikalnih grebenov, ki sodelujejo s kontaktnimi vzmetmi, katere potekajo na eni strani stikalnega valja prečno k njegovi osi, pri čemer so kontaktne vzmeti in njihovi nasprotni kontakti povezani z električnimi priključnimi elementi. Takšna stikala so namenjena regulaciji oz. krmiljenju električnih priprav, posebno elektrotoplotnahpriprav kot kuhalnih plošč, pečic in podobno.The invention relates to an electric ridge switch with a switch body and a switch cylinder carrying several switch ridges cooperating with contact springs extending on one side of the switch roller transversely to its axis, the contact springs and their opposite contacts being connected to the electrical ones. connecting elements. Such switches are intended for regulation or control. control of electrical appliances, especially electric heaters such as hobs, ovens and the like.

Po mednarodni klasifikaciji patentov spada izum v razred H 01H 5/42.According to the international classification of patents, the invention belongs to class H 01H 5/42.

Tehnični problemA technical problem

Tehnični problem je konstrukcija grebenastega stikala posebno enostavne izgradnje, katere štedi na gradivu in jo je lahko izdelatati in katero potrebuje posebno nizko gradbeno višino.A technical problem is the construction of a reef switch that is particularly easy to build, which saves on materials and is easy to manufacture, and which requires a particularly low construction height.

The second put the switches, which in the heads complement the shape of the body of the switch in the form of panels, covers these isvotllne to the connection openings with electrical conductors, and the bores with the contact vssetl and opposite contacts. With this measure, the construction vi- ciastics are only lower, since some of the electrical conductors extend to the switch body, but this arrangement requires the sapetna construction of the switch. Even with the one-piece® underneath the German usability of the 7 007 5 ^ 5, the building height is still relatively large.

Kontaktne vzmeti 26 in ustrezni nosilci 50 so na svojih, od kontaktov oddaljenih koncih pravokotno zapognjeni in ojačeni z ojačitvenim rebrom. Nahajajo se na navzven usmerjenih notranjih stenah izvotlin 17 v podnožju stikala in so na svojem koncu pričvrščeni z zapognitvami 52, pri čemer segajo skozi dovajalne odprtine 55, ki vodijo od zgoraj ležeče priključne strani stikala v izvotline 51· Skozi te odprtine se dovedejo električni vodniki 20 oz. na njih nameščene vodniške stročnice in se na znan način pritisnejo od steznih vzmeti 49 proti kontaktnim delom 26 in 50 ter zataknilno pritrdijo.For this purpose, the lateral portions 15, 14 are modified in that they have downward openings in which the spring springs 49, which are mainly U-shaped, lie. The contact springs 26 and the corresponding brackets 50 are perpendicularly bent and reinforced by a reinforcing rib at their respective ends from the contacts at the far ends. They are located on the outwardly directed inner walls of the holes 17 at the base of the switch and are fixed at their ends by recesses 52, extending through the feed holes 55 leading from the upper connection side of the switch to the holes 51 · Electric conductors 20 are passed through these openings. oz. guide pulleys are mounted thereon and are pressed in a known manner from clamping springs 49 against contact members 26 and 50 and fastening fastening.

Električno grebenasto stikalo je elektromehanski element, ki se od podobnih tovrstnih stikal razlikuje v drugačni izvedbi delov, ki ga sestavljajo. Tako se njegovo gospodarsko izkoriščanje v ničemer ne razlikuje od tistega, ki je že znano. To velja tako za dele, sestavljene iz izolacijskih snovi, kakor dele, ki sodelujejo v električnih tokokrogih oz. dele, ki so namenjeni premikanju teh kontaktov.An electric ridge switch is an electromechanical element that differs from similar switches in the different design of the parts that make it up. Thus, its economic exploitation is in no way different from what is already known. This applies both to parts made up of insulating materials, as well as to parts that participate in electrical circuits or circuits. parts that are intended to move these contacts.
