Abstract

With the classical electrical plug, it sometimes requires much force anddifficulty to remove the plug from the socket. Usually, the plug or thesocket is damaged in the short- or long-term and also reduces the comfort oflife. This invention ensures that everyone can very easily remove a plug froma socket by using a built-in lever system. This system ensures that the plugpushes itself away from the socket. The lever (1) ensures that the buffer bar(3) pushes axially against the wall by means of hinge (2). Spring (3) ensuresthat if the plug has been removed from the socket, the buffer bar (3) iswithdrawn as well.<IMAGE>

  ELEKTRISCHE STEKKER VOORZIEN VAN EEN HEFBOOMSYSTEEM OM MET GERINGE KRACHT DE STEKKER UIT STOPCONTACTEN TE HALEN De uitvinding zorgt ervoor dat elektrische stekkers voorzien worden van een ingebouwd hefboomsysteem zodanig dat ze viot uit een stopcontact kunnen verwijderd worden. 



    Momenteel   zijn elektrische stekkers in gebruik die soms niet vlot uit het stopcontact verwijderbaar zijn omdat ze erin spannen. Dit probleem stelt zich zowel bij elektrische stekkers van huishoudapparatuur als bij deze van industriële machines. Het gevolg is dat ofwel het stopcontact ofwel de stekker beschadigd geraken bij het proberen te verwijderen van de stekker. Ook mensen met mindere krachtcapaciteiten kunnen hierdoor problemen hebben om de stekker uit een stopcontact te trekken. 



  Een aantal stekkers bestaan reeds met een oog eraan zodat eraan getrokken kan worden, doch dit is niet altijd voldoende efficiënt omdat er soms niet-axiaal aan getrokken kan worden. 



  Vandaar dat deze nieuwe stekker omgekeerd werkt en zichzelf uit het stopcontact duwt door middel van een ingebouwd hefboomsysteem. Op tekening TEK1 is de werking van het inwendige mechanisme getekend. Door aan hefboom 1 te trekken zal deze gaan scharnieren rond as 2 waardoor stang 3 naar buiten beweegt en op die manier tegen het stopcontact gaat aandrukken waardoor de stekker achteruit wordt geduwd. De dimensionering gebeurt zodanig dat er zeer weinig kracht nodig is om de stekker uit het stopcontact te duwen. 



  Bovendien is de drukkracht kompleet axiaal en loodrecht op de stekkerwand gericht zodat de stekker er op een perfekte manier uitgaat. 



  Het geheie hefboomsysteem kan in bestaand stekkers worden ingebouwd aangezien het tussen twee vertikale plaatjes kan gemonteerd worden en op die manier zorgt voor een complete scheiding tussen elektrisch en mechanisch gedeelte. Op die manier kan aan de geldende veiligheidsnormen worden voldaan inzake elektrische veiligheid. Bovendien kunnen, mits een kleine technische aanpassing (in casu het verlengen van de stekkerkop om voldoende ruimte te hebben tussen de stekkerwand en hefboom 1), alle bestaande stekkers van dit systeem voorzien worden. 



  Tekening TEK 1 toont de praktische uitvoeringswijze van een eenvoudige eletrische stekker met aarding. Het veertje 4 zorgt ervoor dat indien de stekker niet in het stopcontact steekt het stangetje 3 ingetrokken wordt. 



  Het spreekt voor zich dat dit systeem op alle stekkers van toepassing is.

  ELECTRICAL CONNECTOR FITTED WITH A LEVER SYSTEM FOR LOW-POWERED REMOVAL OF THE CONNECTOR FROM SOCKETS The invention ensures that electrical plugs are fitted with a built-in lever system so that they can be removed from a socket.



    Currently, electrical plugs are in use that are sometimes not easy to remove from the socket because they clamp in. This problem arises both with electrical plugs of household appliances and those of industrial machines. As a result, either the outlet or the plug will be damaged when attempting to remove the plug. People with less power capacities can also have problems pulling the plug from a socket.



  A number of plugs already exist with one eye on them so that they can be pulled, but this is not always efficient because it can sometimes be pulled non-axially.



  That is why this new plug works in reverse and pushes itself out of the socket by means of a built-in lever system. The working of the internal mechanism is shown in drawing TEK1. Pulling on lever 1 will cause it to pivot around shaft 2, causing rod 3 to move outward and thus to push against the socket, pushing the plug backwards. The sizing is done in such a way that very little force is required to push the plug out of the socket.



  In addition, the pressure force is directed axially and perpendicular to the plug wall so that the plug goes out in a perfect way.



  The entire lever system can be built into existing plugs as it can be mounted between two vertical plates and thus ensures a complete separation between electrical and mechanical parts. In this way, the applicable safety standards regarding electrical safety can be met. In addition, subject to a minor technical adjustment (in this case extending the plug head to have sufficient space between the plug wall and lever 1), all existing plugs can be fitted with this system.



  Drawing TEK 1 shows the practical implementation of a simple electrical plug with earthing. The spring 4 ensures that if the plug is not inserted into the socket, the rod 3 is retracted.



  It goes without saying that this system applies to all plugs.

CONCLUSIES Het gebruik van een hefboomsysteem om elektrische stekkers uit het stopcontact te halen zorgt ervoor dat deze stekkers zeer gemakkelijk uit een stopcontact te verwijderen zijn. CONCLUSIONS The use of a lever system to remove electrical plugs from the socket makes these plugs very easy to remove. Door dit principe in bestaande stekkers in te bouwen kan men door middel van het trekken aan hefboom 1 het stootstangetje 2 naar buiten doen bewegen waardoor de stekker zichzelf uit het stopcontact duwt. Deze kracht wordt axiaal op de contactdoos overgebracht zodat er een perfekte scheiding optreedt tussen de stekker en het stopcontact. By incorporating this principle in existing plugs, the push rod 2 can be moved outwards by pulling lever 1, so that the plug pushes itself out of the socket. This force is transferred axially to the socket so that there is a perfect separation between the plug and the socket. Door dit hefboomsysteem tussen twee vertikale (bij voorkeur kunstof) scheidingswanden te plaatsen is er een volledige elektrische en mechanische scheiding zodanig dat er ook voldaan wordt aan de veiligheidsnormen ter zake. By placing this lever system between two vertical (preferably plastic) partitions, there is a complete electrical and mechanical separation such that the relevant safety standards are also met.
