Elektrisk G. E. ERIKSSON, GOTEBORG. stiekkontakt med automatisk strombrytare. Electric G. E. ERIKSSON, GOTEBORG. socket with automatic switch.

Uppfinningen hanfor sig till stick-kontakter vid olika elektriska uppvarmningsanordningar, vilka aro avsedda att yara inkopplade endast miss begransad tid och som kunna fororEaka eldsvada, om nadig varsamhet ej iakttages. The invention relates to plug-in sockets in various electric heating devices, which are intended to be switched on only for a limited time and which can cause a fire if careful care is not taken.

Avsikten med uppfinningen ar att astadkomma sakerhet mot eldfara vid elektriska strykjarn, kastruller o. dyl. I vissa fall foreligger icke flagon risk for eldfara, men dä kan det i stallet intraffa, att apparaten spiv skadas. Aven i sadana fall medlar en kontakt enligt uppfinningen stora fordelar. The object of the invention is to provide safety against fire hazards in electric irons, pots and the like. In some cases there is no significant risk of fire, but then it may occur in the stable that the appliance spike is damaged. Even in such cases, a contact according to the invention offers great advantages.

Det Onskade syftet uppnits enkelt och hogst tillforlitligt med en stick-kontakt med automatisk strombrytare, kannetecknad dam att en isolerad kontaktkropp medelst en tryckknapp mot verkan ay en ljader kan foras i kontaktlage mellan tva metallfjadrar, dar den. kvarhalles, sa. hinge kontakten ej är uppviirmd Over en miss temperatur, av ett sparrande organ, mot vilket en ansats pa kontaktkroppen anligger, och vilket av ett temperaturberoende organ fOres at sidan, sa. att, nar kontakten erhaller miss temperatur, sparrorganet fores ur vagen for ansatsen och kontaktkroppen ay fjadern automatiskt fares ur kontaktlaget. The desired purpose is achieved easily and very reliably with a plug with automatic switch, can be drawn lady that an insulated contact body by means of a push button against the action of a sound can be carried in contact between two metal springs, where it. kvarhalles, sa. hinge contact is not heated Over a wrong temperature, by a sparring member, against which a shoulder on the contact body abuts, and which by a temperature-dependent member is carried to the side, so. that, when the contact receives the wrong temperature, the ratchet member is moved out of the carriage for the shoulder and the contact body on the spring is automatically removed from the contact layer.

Det sparrande organet utgores ay en kam pa en vridbar cylindrisk kropp. The sparring member is formed on a cam on a rotatable cylindrical body.

Det temperaturberoende organet kan besta av en bimetallspiral, som med sin ena finde är fastlagd i kontakthuset och med sin andra an-de fir inlagd i en skara i den cylindriska kroppen. The temperature-dependent member may consist of a bimetallic spiral, which with its one fin is fixed in the contact housing and with its other fin inserted in a groove in the cylindrical body.

Kontakthuset ar forsett rned flera narliggande skaror, van i bimetallspiralens ande kan inlaggas for att installa den temperatur, yid vilken strommen brytes. The contact housing is provided with several adjacent joints, used in the spirit of the bimetallic spiral can be inserted to set the temperature at which the current is broken.

Uppfinningen askadliggores a bifogade ritning, varvid fig. 1 visar kontakten med locket avtaget, fig. 2 stickkontakten fran sidan, fig. 3 ett ytterlock med bimetallspiral, och fig. 4 tryckknappen med kontaktkroppen frail sidan. The invention is illustrated in the accompanying drawing, in which Fig. 1 shows the contact with the lid removed, Fig. 2 the plug from the side, Fig. 3 an outer lid with bimetallic spiral, and Fig. 4 the push button with the contact body from the side.

Stickkontakten bestar i det visade utf6- ringsexemplet ay tva delar 1, 2 med ett mindre ytterlock 3 pa delen 1, vilka samtliga aro utforda ay isolerande material. The plug consists in the illustrated embodiment of two parts 1, 2 with a smaller outer cover 3 on the part 1, all of which are to challenge the insulating material.

Strom tillfores kontakten genom en sladd 4, vilken infOres i kontaktdelen. 2 genom en gumnaihylsa 5 pa kant att. De bada tradarna sladden forbindas med var sin klamskruv 6, 7, vilken senare star i forbindelse med en i kontaktens fot liggande kontakthylsa 9 fOr kontaktstift pa ett strykjarn eller dylikt. Power is supplied to the contact through a cord 4, which is inserted into the contact part. 2 through a rubber sleeve 5 on the edge that. The two wires are connected to the cord with their respective clamping screw 6, 7, which later is connected in connection with a contact sleeve 9 located at the base of the contact for contact pins on an iron or the like.

Traden yid skruven 6 an i kontakt med en platskena 10, vilken gar in i en forsankning 11 i delen 1 och avslutas med en fjadrande del 12. Nara dess bap ligger en annan fjadrande plat 13, vilken star i forbindelse med hylsan 8. Den andra skruven 7 star i direkt forbindelse med hylsan 9 genom en platskena 14 eller dylikt. The wire yid the screw 6 in contact with a plate rail 10, which enters a recess 11 in the part 1 and ends with a resilient part 12. Near its bap lies another resilient plate 13, which is connected to the sleeve 8. The second the screw 7 is in direct connection with the sleeve 9 through a seat rail 14 or the like.

I kontaktdelen 1 finnes en tryckknapp 15, vilken med en stang 16 fir forbunden med en kontaktkropp 17, vilken har en ansats 18. Tryckknappen 15 paverkas ay en fjader 19, vilken strayar att fora kontaktkroppen 17 fran kontaktstallet mellan bagarna 12 och 13. In the contact part 1 there is a push button 15, which with a rod 16 is connected to a contact body 17, which has a shoulder 18. The push button 15 is actuated by a spring 19, which strains to move the contact body 17 from the contact stall between the bakers 12 and 13.

Kontaktens utforande ar sadant, att den aldrig behover borttagas fran stryhjarnet el. dyl. Med tryckknappen 15 inkopplas jarnet, detsamma är kallt. Ansatsen 18 ph kontaktkroppen 17 kommer att anligga mot en kam 20 pa en liten, vridbart anbragt cylinder 21 ay isolerande material, vilken paverkas av en bimetallfjader 22, som an inlagd i ytterlocket 3. Nar jarnet uppvarmes vrider bimetallfjadern 22 eylindern 21 och nar jarnet nat. Over arbetstemperaturen har cylindern 21 vridits sa, mycket, att kammen 20 vridits helt ur vagen for ansatsen 18. Kontaktkroppen 17 10- res fran kontaktstallet ay fjadern 19 och kan icke aterfOras i varaktig kontakt, fOrran jar-nets temperatur sjunkit under dess arbetstemperatur. The design of the contact is such that it never needs to be removed from the iron or the like. dyl. With the push button 15 the iron is switched on, the same is cold. The shoulder 18 ph contact body 17 will abut against a cam 20 on a small, rotatably mounted cylinder 21 of insulating material, which is actuated by a bimetallic spring 22, as inserted in the outer cover 3. When the iron is heated, the bimetallic spring 22 turns the cylinder 21 and when the iron is wet . Above the working temperature the cylinder 21 has been rotated so much that the cam 20 has been rotated completely out of the way of the shoulder 18. The contact body 17 is removed from the contact housing of the spring 19 and cannot be returned in permanent contact until the temperature of the iron has fallen below its working temperature.

Temperaturgransen kan varieras medelst bimetallspiralen 22, exempelvis kan dess ena ande 23 inlaggas i olika skaror 24, varigenona olika vridningsvinklar erfordras for att frig& ra ansatsen 18. The temperature limit can be varied by means of the bimetallic spiral 22, for example its one end 23 can be inserted in different notches 24, whereby different angles of rotation are required to release the shoulder 18.

Stickkontaktens olika delar fastas lampligen samman pa kant satt medelst. skruvar. 2— — Uppfinningen ãr icke begransad till enbart hdr visade och beskrivna utforingsform utan kan forandras Mom lumen for efterfoljande patentansprak. The various parts of the socket are suitably fastened together on the edge set by means. screws. The invention is not limited to the embodiment shown and described only, but can be changed within the scope of subsequent patent claims.
