Description

10 15 20 25 30 35 455 031 hopnitad med en skyddskontaktbygel, som ligger i en urtagning på stickproppens framsida. _ Vid de bakre ändarna av de båda kontaktstiften och av skyddskontaktstif- tet är utformade skruvklämmor, som är isolerande omgivna av tre vid bryggan an- ordnade kammare. De till kontaktstiften hörande kamrarna har en in-föringsöpp- ning, som är riktad mot den främre delen, medan denna införingsöppning vid den till skyddakontsktstiftet hörande kammaren är anordnad mot den bakre delen. Så länge skyddskontaktatiftet är hopskruvat medd skyddskontaktbygelo, hills bryggan i den främre delen. Om man lossar förbindningsskruven från skyddskontsktbygeln, så kan bryggan tas bort från den främre delen, varvid kontaktstiften kvarblir i sitt läge, medan skyddskontaktstiftet utdras tillsammans dïrmed. Skyddskontakten kan också vara hopnitad med skyddskontaktbygeln- I ' Anslutningen av ksbelïndarna av den i instickningsriktningen vid dragav- lastningen fastgjorda kabeln underlättas särskilt, genom att analntningaöppning- arna till de tre skruvklïmmorna är vända mot kabelïndarna. För att införa kabel- ändarna in i skruvkläzmnorna är kamrarna för kontaktstiften på detta ställe för- sedda med häl. Bärutöver finns pâ sidan anordnade kammaröppningsr, som stir i förbindelse med införingsöppningsrna och erbjuder plats för klïmskruvarna. För att utnyttja stickproppens inre utrymme väl, är klïmskruvarns inskruvade pi den sida av skruvklämmorna, som är vänd från skruvkanalerna. 10 15 20 25 30 35 455 031 riveted with a protective contact bracket, which is located in a recess on the plug front. _ At the rear ends of the two contact pins and of the protective contact pins are screw clamps, which are insulated surrounded by three at the bridge arranged chambers. The chambers belonging to the contact pins have an insertion opening which is directed towards the front part, while this insertion opening at it the chamber belonging to the protective contact pin is arranged towards the rear part. So as long as the protective contact pin is screwed together with the protective contact bracket, hills the bridge in the front part. If you loosen the connecting screw from the protective bracket, then the bridge can be removed from the front part, leaving the contact pins in its position, while the protective contact pin is extended together therewith. The protective contact can also be riveted with the protective contact bracket- I ' The connection of the ksbelindarna of the in the insertion direction at the pull-off the load attached to the load is facilitated in particular, by the screws for the three screw clamps face the cable ends. To introduce cable the ends into the screw clamps, the chambers for the contact pins at this point are seen with heels. In addition, there are chamber openings arranged on the side, which project into connection with the insertion openings and offers space for the clamping screws. For to make good use of the internal space of the plug, the clamping screws are screwed into the side of the screw clamps, which are facing away from the screw channels.

I linje med skruvkanalernsvid den främre delen 'dr också utformade skruvkanaler i den bakre delen. På grund av dessa ïr den bakre delens inre utrymme avsevärt inskränkt- För att ändå erbjuda tillräckligt utrylse för drag- avlsstningen och för kabeln, 'är för dragavlaatningen utformad en tvïrbalk vid änden av steget, vilken tvörbalk ör förskjuten i förhållande till förbindnings- linjen mellan de båda skruvkanalerna i 90°.In line with the screw channels at the front part 'dr also designed screw channels in the rear part. Due to these, the rear part is the interior space considerably limited- In order to still offer sufficient space for towing for the drawbar, a crossbeam is formed at the drawbar end of the step, which crossbeam is offset relative to the connecting the line between the two screw channels at 90 °.

För att undvika att bryggan vid monteringen vrids i den bakre delen, är bryggans änder olika forimde och de i bakre delen utformade stödavsatserna ör anpassade så till de motsvarande ändarna, att bryggan bara i ett lige passar ihop med den bakre delen. Ytterligare är vid bryggan anordnad en akiljevïgg nel- lan ett kontaktstift skruvklämms och skyddskontsktstiftets skruvklïmma.To prevent the bridge from being rotated in the rear part during assembly, is the ends of the bridge are different forimde and the support ledges designed in the rear part ör adapted so to the corresponding ends, that the bridge only in one straight fits together with the rear part. In addition, an Achilles' wall is arranged at the bridge. lan a contact pin screw clamp and the protective contact pin screw clamp.

För att utvidga stickproppens användningsområde kan dennas bakre del för- ses med en andra kabelutloppsöppning, som ligger i införingsriktningen, och den icke utnyttjade ksbelutloppsöppningen kan tillslutas med šhﬂälp av en propp.To extend the application area of the plug, its rear part can be extended is seen with a second cable outlet opening, located in the insertion direction, and it unused ksbel outlet opening can be closed with the help of a plug.
