Description

ELEKTRISK STICKPROPP UPPFINNINGENS TEKNISKA OMRADE OCH BAKGRUNDS5 TEKNIK Foreliggande uppfinning avser en elektrisk stickpropp innefattande en stiftbaskropp med atminstone tva fran och vinkelratt re- lativt en andyta hos denna parallellt i en hopkopplingsrikt- ning utskjutande stift utformade far inforing i motsvarande honorgan, och ett element anordnat rorligt relativt stiftbaskroppen i namnda hopkopplingsriktning for att i ett hopkopplingstill- stand hos stickproppen i ett isarkopplingslage traffa och trycka mot namnda honorgan omgivande ytor for att mojliggora uttryckning av stiften ur namnda honorgan genom alstrande av reaktionskrafter. TECHNICAL FIELD AND BACKGROUND ART OF THE INVENTION relative to the pin base body in said coupling direction to, in a coupling state of the plug in an ice coupling layer, hit and press against said female means surrounding surfaces to enable expression of the pins from said female means by generating reaction forces.

Darvid avser uppfinningen forutom allehanda typer av stickprop- par for inforande i elektriska vagguttag aven sadana for hopkoppling med andra elektriska uttag, sasom hos forlangningssladdar, sladdvindor och dylikt. In addition to all kinds of plugs for insertion into electrical cradle sockets, the invention also relates to those for connection with other electrical sockets, such as extension cords, cord wires and the like.

For att losa en stickforbindning i vilken en namnd stickpropp in- gar kravs ett anbringande av en icke oansenlig dragkraft av en person pa stickproppen. Att uppbringa denna kraft upplevs som speciellt svart for barn, aldre personer och personer med av annan anledning, sasom handikapp, nedsatt styrka eller svarighet 30 att greppa foremal. Av denna anledning finns en overhangande risk att personen i fraga valjer att istallet dra i den till stickproppen anslutande elektriska sladden, vilket till sist kan leda till att elektriska ledare i denna sladd blottas eller lossnar fran stickproppen, som forutom att den da blir obrukbar kan leda till elekt- 35 riska olyckor. Aven personer med normalstyrka har en tendens att finna det bekvamare att dra i den elektriska sladden for att losa en stickproppsfarbindning. Problemet är speciellt Overhang- 1 537 6 ande for stickproppar som ingar i elektriska forbindningar som ofta upprattas och loses, sasom stickproppar for elektrisk utrustning, sasom dammsugare, hartorkar och borrmaskiner. In order to loosen a plug connection in which a named plug is included, an application of a not insignificant traction force of a person to the plug is required. Applying this power is perceived as especially black for children, elderly people and people with for other reasons, such as disability, reduced strength or responsibility 30 to grasp objects. For this reason, there is an imminent risk that the person in question chooses to pull the electrical cord connected to the plug instead, which may eventually lead to electrical conductors in this cord being exposed or detached from the plug, which in addition to becoming unusable can lead to electrical accidents. Even people of normal strength tend to find it more comfortable to pull on the electrical cord to loosen a plug connection. The problem is particularly overhanging for plugs that are involved in electrical connections that are often set up and loosened, such as plugs for electrical equipment, such as vacuum cleaners, hair dryers and drills.

For att losa ovannamnda problem har elektriska stickproppar av inledningsvis namnt slag tagits fram. Genom att en sadan stickpropp är forsedd med ett dylikt element som i hopkopplingsriktningen trycks mot de ytor som omger honorganen hos ett farbindningsdon som den elektriska stickproppen ska forbindas med for uttryckning av stiften ur dessa honorgan kan den forbindning som stickproppen ingar i forhallandevis bekvamt losas utan krav pa anbringande av nagra dragkrafter pa stickproppen, och inte heller maste personen som manovrerar stickproppen ha formaga att ens greppa denna. Sadana elektriska stickproppar är kanda 15 bl a genom EP 1 071 169 Al och US 4 045 106. Dessa tidigare kanda stickproppar är dock i vissa hanseenden komplicerat uppbyggda och/eller har erhallit forhallandevis betydande dimensioner i forhallande till en konventionell stickpropp for att mojligOra den uppfinningsenliga "uttryckningsfunktionen". In order to solve the above-mentioned problems, electrical plugs of the initially named kind have been developed. By providing such a plug with such an element which in the coupling direction is pressed against the surfaces surrounding the female members of a connecting connector to which the electrical plug is to be connected for expression of the pins from these female members, the connection in which the plug is relatively can be loosened without requirement. on the application of any tensile forces to the plug, nor must the person maneuvering the plug be able to even grip it. Such electrical plugs are known, inter alia, from EP 1 071 169 A1 and US 4 045 106. However, these previously known plugs are in some respects complicated to construct and / or have acquired relatively significant dimensions in relation to a conventional plug in order to enable the invention according to the invention. "expression function".

SAMMANFATTNING AV UPPFINNINGEN Syftet med foreliggande uppfinning är att tillhandahalla en elektrisk stickpropp av inledningsvis definierat slag, vilken är forbatt- rad i atminstone nagot hanseende relativt tidigare kanda sadana stickproppar. SUMMARY OF THE INVENTION The object of the present invention is to provide an electrical plug of an initially defined type, which is improved in at least somewhat relative to previously known such plugs.

Detta syfte uppnas enligt uppfinningen genom att tillhandahalla en stickpropp med sardragen hos bifogade patentkrav 1. This object is achieved according to the invention by providing a plug with the features of appended claims 1.

Genom ett anordnande av en hattartad kapa pa vilken en tryckkraft kan anbringas for att forflytta denna relativt stiftbaskroppen och darigenom forflytta elementet i samma riktning relativt stiftbaskroppen kan en isarkoppling med enkla medel och lite till- kommande platsbehov relativt en konventionell stickpropp astad- kommas. 2 537 6 Enligt en utforingsform av uppfinningen är namnda element utformat rorligt relativt stiftbaskroppen forbi namnda andyta far att i namnda isarkopplingslage trycka mot ytor som namnda honorgan mynnar i och som namnda stift är utformat att vara inforda i i namnda hopkopplingstillstkid hos stickproppen. En sklan stick- propp kan uppfylla sin funktion vad galler isarkopplingsmajligheten via anbringande av en tryckkraft pa kapan oavsett utseendet pa det forbindningsdon, sa'som vagguttag, som den är hopkopplad med, vilket inte är fallet has en del tidigare kanda sklana elektriska stickproppar, hos vilka namnda element inte skjuter forbi namnda andytor utan är avsett att verka pa namnda honorgan omgivande ytor pa en annan niva an botten i ett urtag som stickproppen är instucken i. Detta innebar att den uppfinningsenliga stickproppen kan goras kompakt. By arranging a cap-like cap on which a compressive force can be applied to move it relative to the pin base body and thereby move the element in the same direction relative to the pin base body, an ice connection with simple means and little additional space relative to a conventional plug can be achieved. According to an embodiment of the invention, said element is designed movably relative to the pin base body past said face surface in said ice coupling layer to press against surfaces into which said female means open and in which said pin is designed to be inserted into said coupling attachment of the plug. A slotted plug can fulfill its function as far as the possibility of ice connection is concerned by applying a compressive force to the cover regardless of the appearance of the connector, such as the cradle socket with which it is connected, which is not the case with some previously known slanted electrical plugs. which said elements do not project past said face surfaces but are intended to act on said female surfaces surrounding surfaces at a different level from the bottom of a recess into which the plug is inserted. This meant that the plug according to the invention can be made compact.

Enligt en annan utforingsform av uppfinningen innefattar stickproppen en hylsa anordnad att mottaga stiftbaskroppen och sjalv mottagen i och omgiven av namnda kapa och forskjutbar atminstone delvis in i och ut ur kapan vid forflyttning av Wan rela- tivt stiftbaskroppen i respektive motsatt namnda hopkopplings- riktning. Kombinationen av stiftbaskropp, en denna hysande hylsa och en hylsan hysande kapa resulterar i en enkel design och tillforlitlig fun ktion hos den uppfinningsenliga stickproppen. According to another embodiment of the invention, the plug comprises a sleeve arranged to receive the pin base body and itself received in and surrounded by said sheath and displaceable at least partially into and out of the sheath when moving the Wan relative pin base body in respective opposite coupling direction. The combination of a pin base body, a housing accommodating this sleeve and a sleeve housing the sleeve results in a simple design and reliable function of the plug according to the invention.

Enligt en annan utforingsform av uppfinningen är hylsan utformad att i namnda hopkopplingstillstand hos stickproppen ha sin i namnda hopkopplingsriktning sett stiftnara ande belagen i den region av stiftbaskroppen dar stiften skjuter ut ur denna. According to another embodiment of the invention, the sleeve is designed to have, in the said coupling state of the plug, its pins seen in the said coupling direction in the region of the pin base body where the pins protrude therefrom.

Enligt en annan utforingsform av uppfinningen är hylsan utformad att med yttervaggar bilda stickproppens yttre begransning utformad att samverka med vaggar hos ett uttag vid inskjutning av stickproppen i ett uttag med ytorna som direkt angransar till honorganen nedsankta i en av namnda uttagsvaggar avgransad 35 bottenhalskavitet. Genom en sklan utformning hos hylsan kommer hylsan och stiftbaskroppen tillsammans att fungera som en konventionell stickpropp inford i ett namnt uttag, och del finns 3 537 6 darvid ingen mojlighet att i det fall den uppfinningsenliga stickproppen skulle vara isartagen felaktigt anvanda endast stiftbaskroppen ensam som stickpropp. According to another embodiment of the invention, the sleeve is designed to form the outer boundary of the plug with outer walls designed to co-operate with cradles at a socket when inserting the plug into a socket with the surfaces directly adjacent to the female members immersed in a bottom neck cavity delimited by said socket cradles. Due to a slender design of the sleeve, the sleeve and the pin base body together will function as a conventional plug inserted in a named socket, and there is no possibility that in case the plug according to the invention would be inserted incorrectly use only the pin base body alone as a plug.

Enligt en annan utforingsform av uppfinningen är hylsan utformad att bilda namnda element. Harigenom uppnas den uppfinningsenliga isartryckningsfunktionen pa enkelt satt och hylsan far en dubbelfunktion genom att den hyser stiftbaskroppen och aven astadkommer uttryckning av stiften ur honorganen vid applice- rande av en tryckkraft pa kapan i hopkopplingsriktningen. Denna utformning är speciellt fordelaktig vid en stickpropp enligt den narmast foregaende diskuterade utf6ringsformen, hos vilken da hylsan kommer att halla stickproppen i uttaget och med andkanter pressas mot botten hos namnda bottenhalskavitet. According to another embodiment of the invention, the sleeve is designed to form said element. In this way, the ice-pressing function according to the invention is achieved in a simple manner and the sleeve has a double function in that it houses the pin base body and also provides expression of the pins from the female members when applying a compressive force to the cutter in the coupling direction. This design is particularly advantageous in a plug according to the most recently discussed embodiment, in which the sleeve will then hold the plug in the socket and be pressed against the bottom of said bottom neck cavity with duck edges.

Enligt en annan utforingsform av uppfinningen har kapan, sett i namnda hopkopplingsriktning, ett av en innervagg hos den definierat inre tvarsnitt som fullstandigt tacker yttertvarsnitten hos saval hylsan som stiftbaskroppen sett i denna riktning. Harige- nom kommer inte flagon del av stickproppen att i tvarled relativt hopkopplingsriktningen skjuta ut mer an kapan, sa att stickproppen blir kompakt och risk for att ofrivilligt skada delar av den vid dess hantering minimeras. According to another embodiment of the invention, the cutter, seen in said coupling direction, has one of an inner cradle of the defined inner cross-section which completely notches the outer cross-sections of the saval sleeve as the pin base body seen in this direction. As a result, the flake part of the plug will not protrude more than the hood at a transverse direction relative to the coupling direction, so that the plug becomes compact and the risk of involuntarily damaging parts of it during its handling is minimized.

Enligt en annan utforingsform av uppfinningen är transmissions- inrattningen utformad att overfora en rorelse av kapan relativt hylsan i hopkopplingsriktningen till en rorelse av stiftbaskroppen relativt hylsan i motsatt riktning. According to another embodiment of the invention, the transmission device is designed to transmit a movement of the cap relative to the sleeve in the coupling direction to a movement of the pin base body relative to the sleeve in the opposite direction.

Enligt en vidareutveckling av sistnamnda utf6ringsform innefattar transmissionsinrattning medel hos kapan utformade att vid en namnd rorelse av kapan relativt hylsan i hopkopplingsriktningen framf6r sig i denna riktning skjuta en i hylsan mottagen forsta transmissionsdel utformad att samverka med en pa stiftbaskrop- pen anordnad andra transmissionsdel for att forflytta stiftbas- kroppen mat i hylsan. En sadan utformning hos transmissionsinrattningen är enkel och kan ges en tillforlitlig funktion. 4 537 6 Enligt en annan utforingsform av uppfinningen innefattar transmissionsinrattningen atminstone en kuggstang och ett darmed samverkande kugghjul, varvid hos en vidareutveckling darav kuggst6ngen är fast forbunden med stiftbaskroppen och kugghju- let är roterbart lagrat i hylsan. I en vidareutveckling darav innefattar transmissionsinrattningen en av namnda kapa paverkbart anordnad kuggstang utformad att samverka med namnda kugghjul for overforing av en rorelse hos kapan relativt hylsan till en rorelse av stiftbaskroppen relativt hylsan och darmed relativt kà- pan. According to a further development of the latter embodiment, the transmission device comprises means of the hood designed to push a first transmission part received in the sleeve in a directional movement of the hood relative to the sleeve in the direction of coupling, designed to cooperate with a second part pin base- body food in the sleeve. Such a design of the transmission device is simple and can be given a reliable function. According to another embodiment of the invention, the transmission device comprises at least one gear rack and a gear cooperating therewith, a further development of which the gear rack is fixedly connected to the pin base body and the gear wheel is rotatably mounted in the sleeve. In a further development thereof, the transmission device comprises a gear rod arranged by said cap to actuate to cooperate with said gear for transmitting a movement of the cap relative to the sleeve to a movement of the pin base body relative to the sleeve and thus relative to the cover.

Enligt en annan utforingsform av uppfinningen innefattar transmissionsinrattningen atminstone ett langstrackt flexibelt organ, sasom en lina, och medel, sasom hjul, utformade att omlanka det langstrackta organet. Detta utgor en alternativ majlighet att realisera transmissionsinrattningen hos en uppfinningsenlig stickpropp. According to another embodiment of the invention, the transmission device comprises at least one elongate flexible member, such as a rope, and means, such as wheels, designed to deflect the elongate member. This constitutes an alternative possibility of realizing the transmission device of a plug according to the invention.

Enligt en annan utforingsform av uppfinningen innefattar stick- proppen ett fjaderorgan anordnat att verka pa kapan relativt stiftbaskroppen i en riktning motsatt namnda hopkopplingsriktning och vara forspand i ett vilolage, och fjaderorganet är utformat att samverka med kapan sa att for en namnd forflyttning av kapan i 25 hopkopplingsriktningen relativt stiftbaskroppen kravs applicerande av en fjaderorganets fjaderkraft overvinnande kraft pa Ica-pan i namnda hopkopplingsriktning. Harigenom sakerstalls att stickproppen inte ofrivilligt overfors i helt eller delvis isarkopplat tillstand och darmed sakert halls i hopkopplingstillstandet nar sa är onskat samt alltid atervander till ett inbordes lage hos kapan och stiftbaskroppen som motsvarar namnda vilolage sa snart ingen yttre tryckkraft langre appliceras pa kapan. According to another embodiment of the invention, the plug comprises a spring means arranged to act on the cap relative to the pin base body in a direction opposite to said coupling direction and be prestressed in a resting layer, and the spring means is designed to cooperate with the cap so that for a named movement of the cap in 25 the coupling direction relative to the pin base body is required to apply a spring force of the spring member overcoming force on the Ica-pan in said coupling direction. This ensures that the plug is not involuntarily transferred in a fully or partially disassembled state and thus safely kept in the coupling state when desired and always returns to an inboard layer of the hood and the pin base body corresponding to the said resting layer as soon as no external compressive force is applied to the hood.

Enligt en vidareutveckling av sistnamnda utforingsform är fjader- organet anordnat att verka mellan kapan och stiftbaskroppen. According to a further development of the latter embodiment, the spring member is arranged to act between the hood and the pin base body.

Darvid är med fordel fjaderorganet en tryckfjader utformad att 537 6 tryckas ihop under lagrande av potentiell energi vid forflyttning av kapan relativt stiftbaskroppen i hopkopplingsriktningen. In this case, the spring means is advantageously a compression spring designed to be compressed during storage of potential energy when the cap is moved relative to the pin base body in the coupling direction.

Enligt en annan utforingsform av uppfinningen innefattar stick- proppen ett medel utformat att i ett laslage lasa kapan relativt stiftbaskroppen vad galler rorelse i hopkopplingsriktningen for att tillata inforing av namnda stift i namnda honorgan genom anbringande av en tryckkraft pa kapan i hopkopplingsriktningen, och namnda lasmedel är overforbart till ett frigoringslage for att tillata rorelse av kapan i hopkopplingsriktningen relativt stiftbas- kroppen. Genom anordnande av ett sadant lasmedel kan hopkoppling och isarkoppling av stickproppens stift relativt namnda honorgan enkelt och sakert astadkommas. According to another embodiment of the invention, the plug comprises a means designed to weld the cap in a welding position relative to the pin base body as far as movement in the coupling direction is concerned to allow insertion of said pin in said female means by applying a compressive force to the cap in the coupling direction, transferable to a release layer to allow movement of the hood in the coupling direction relative to the pin base body. By arranging such a welding means, coupling and ice-coupling of the pin of the plug relative to the said female means can be achieved easily and safely.

Enligt en annan utforingsform av uppfinningen är namnda ele- ment stavartat utformat, och i ett sadant fall kan transmissionsinrattningen vara utformad att overfora en rorelse av kapan relativt hylsan i hopkopplingsriktningen till en rorelse av det stavartade elementet relativt hylsan och stiftbaskroppen i samma riktning. According to another embodiment of the invention, said element is rod-shaped, and in such a case the transmission device may be designed to transmit a movement of the cap relative to the sleeve in the coupling direction to a movement of the rod-shaped element relative to the sleeve and pin base body in the same direction.

Ytterligare fordelar med samt fordelaktiga sardrag has uppfinningen framgar av den efterfoljande beskrivningen. Additional advantages and advantageous features of the invention will become apparent from the following description.

Den elektriska stickproppen uppvisar en stiftbaskropp 2 med tv5 fran och vinkelratt relativt en andyta 3 hos stiftbaskroppen parallellt i en hopkopplingsriktning hos stickproppen utskjutande stift 4, 5 utformade for inforing i motsvarande honorgan, vilka kan sitta i ett elektriskt vagguttag, i en hylsa i anden hos en forlang- ningssladd eller dylikt, for att via en ledare 6 som utgar fr5n stickproppen ansluta till denna kopplad utrustning till elektricitet. The electrical plug has a pin base body 2 with tv5 from and perpendicular relative to an end face 3 of the pin base body parallel in a coupling direction of the plug projecting pin 4, 5 designed for insertion into corresponding female members, which may sit in an electrical cradle socket, in a sleeve in the spirit of an extension cord or the like, in order to connect to this connected equipment to electricity via a conductor 6 emanating from the plug.

Stiftbaskroppen är mottagen i en hylsa 7, som sjalv är mottagen i 20 en kapa 8 anordnad pa motsatt sida av stiftbaskroppen mot stiften relativt denna kropp. Hylsan 7 är visad ensam i Fig 4. Hylsan 7 är anordnad forskjutbar delvis in i och ut ur kapan vid forflyttning av k5pan 8 relativt stiftbaskroppen i respektive motsatt en riktning for hopkoppling av stickproppen med ett honorgan uppvi- sande foremal, d vsi den riktning som pilen 9 pekar i Fig 2. Hyl- san är utformad att i namnda hopkopplingstillstand has stickproppen, vilket är visat i Fig 2, ha sin i hoppkopplingsriktningen sett stiftnara ande 10 belagen i den region av stiftbaskroppen dar stiften 4, 5 skjuter ut ur denna. Hylsan 7 är utformad att med yt- tervaggar 11 bilda stickproppens yttre begransning utformad att samverka med vaggar has ett uttag vid inskjutning av stickproppen i ett uttag med ytorna 12 som direkt angransar till honorganen nedsankta i en av uttagsvaggarna avgransad bottenhalskavitet 13. The pin base body is received in a sleeve 7, which itself is received in a cap 8 arranged on the opposite side of the pin base body towards the pins relative to this body. The sleeve 7 is shown alone in Fig. 4. The sleeve 7 is arranged slidably partly into and out of the housing when moving the cover 8 relative to the pin base body in the opposite direction for coupling the plug with a female member having a shape, i.e. the direction arrow 9 points in Fig. 2. The sleeve is designed so that in said coupling state the plug, which is shown in Fig. 2, has its pin seen in the direction of coupling in the region of the pin base body where the pins 4, 5 project from it. The sleeve 7 is designed to form the outer boundary of the plug with outer cradles 11, designed to cooperate with cradles, has a socket when inserting the plug into a socket with the surfaces 12 which directly adjoin the female members sunk into a bottom neck cavity 13 delimited by the socket cradles.

Stickproppen uppvisar vidare en transmissionsinrattning utformad att overfora en rorelse av kapan 8 relativt hylsan 7 i hop- 7 537 6 kopplingsriktningen 9 till en rorelse av stiftbaskroppen 2 relativt hylsan i motsatt riktning. For att astadkomma detta innefattar transmissionsinrattningen en vid stiftbaskroppens motsatt stiften belagna ande anordnad kuggstang 14 och invandigt i hylsan 7 roterbart anordnade kugghjul 15 anordnade i ingrepp pa var sida med kuggstangen 14. Transmissionsinrattningen innefattar vidare en transmissionsdel 16 bildad av tva kuggstanger 17, 18 inbordes stelt forbundna via ett tvarstycke 19. Transmissionsdelen 16 ar visad frankopplad fran andra delar hos stickproppen i Fig 4. The plug further has a transmission device designed to transmit a movement of the cap 8 relative to the sleeve 7 in the coupling direction 9 to a movement of the pin base body 2 relative to the sleeve in the opposite direction. To achieve this, the transmission device comprises a rack 14 arranged on the opposite pins of the pin base body and gears 15 rotatably arranged internally in the sleeve 7 arranged in engagement on each side of the rack 14. The transmission device further comprises a transmission part 17 connected via a crosspiece 19. The transmission part 16 is shown disconnected from other parts of the plug in Fig. 4.

Kuggstangerna 17, 18 hos transmissionsdelen 16 är anordnade i ingrepp med kugghjulen pa motsatt sida, d v s utvandigt, mot stiftbaskroppens kuggstang 14. A spirit 20 of the transmission part 16 is designed to abut against an inner surface 21 of the spirit coated pins opposite the pins 8 to be pushed on by the cap when displacing the cap in the coupling direction 9 relative to the sleeve. The racks 17, 18 of the transmission part 16 are arranged in engagement with the gears on the opposite side, i.e. externally, against the rack 14 of the pin base body.

Ett fjaderorgan i form av en tryckfjader 22 är anordnat att verka mellan namnda invandiga yta 21 hos kapan 8 och en motyta 23 hos stiftbaskroppen i en riktning motsatt hopkopplingsriktningen 9 och vara forspand i ett vilolage (laget enligt Fig 2) hos stickproppen. Fjaderorganet är utformat att samverka med kapan sa att for en forflyttning av kapan i hopkopplingsriktningen 9 relativt stiftbaskroppen kravs applicerande av en fjaderorganets fjader- kraft overvinnande kraft pa kapan i hopkopplingsriktningen. A spring means in the form of a compression spring 22 is arranged to act between said inner surface 21 of the cap 8 and a counter surface 23 of the pin base body in a direction opposite to the coupling direction 9 and to be biased in a resting layer (the layer according to Fig. 2) of the plug. The spring member is designed to co-operate with the cap so that for a movement of the cap in the coupling direction 9 relative to the pin base body it is required to apply a spring force of the spring member overcoming force on the cap in the coupling direction.

Stickproppen innefattar vidare ett medel 24, av vilket har endast en varta samverkande med en urtagning är visad, utformat att i ett laslage lasa kapan 8 relativt stiftbaskroppen, genom att lasa hylsan relativt kapan, vad galler rorelse i hopkopplingsriktningen 9 for att tillata inforing av stiften 4, 5 i honorgan hos ett uttag genom anbringande av en tryckkraft pa kapan i hopkopplingsriktningen. Medlet 24 innefattar vidare icke visade stoppinnar som vid vridande av kapan 8 relativt hylsan laser kapan 8 mot rorelse relativt stiftbaskroppen 2. Detta lasmedel är overforbart till ett frigoringslage far att tillata rorelse av kapan i hopkopplingsriktningen relativt hylsan och darmed stiftbaskroppen, sasom är vi- 8 537 6 sat vid en overforing av stickproppen fran laget enligt Fig 2 till det enligt Fig 3. The plug further comprises a means 24, of which only one wart cooperating with a recess is shown, designed to load the cover 8 relative to the pin base body in a welding layer, by locking the sleeve relative to the cover, which moves in the coupling direction 9 to allow insertion of the pins 4, 5 in female means of a socket by applying a compressive force to the cap in the coupling direction. The means 24 further comprises stop pins (not shown) which, when rotating the cap 8 relative to the sleeve, laser the cap 8 against movement relative to the pin base body 2. This welding means is transferable to a release layer to allow movement of the cap in the coupling direction relative to the sleeve and thus the pin base body. 537 6 was involved in a transfer of the plug from the team according to Fig. 2 to that according to Fig. 3.

Funktionen hos den uppfinningsenliga stickproppen är foljande. The function of the plug according to the invention is as follows.

Nal- stickproppen ska foras in i ett uttag är lasmedlet 24 bringat i ett laslage, sa att den viloposition som stickproppen har i Fig 1 kommer att bibehallas aven om krafter for att forskjuta kapan 8 relativt hylsan appliceras i riktningen av pilen 9. Harigenom är de i stickproppen ingaende delarna ororliga relativt varandra, och stickproppen kan kopplas ihop med ett uttag genom att trycka in stiften 4, 5 i uttagets honorgan genom tryckande p6 k6pans 8 andyta 25. Harigenom uppnas laget enligt Fig 2. If the plug is to be inserted into a socket, the welding agent 24 is brought into a welding position, so that the resting position which the plug has in Fig. 1 will be maintained even if forces for displacing the cover 8 relative to the sleeve are applied in the direction of the arrow 9. the parts engaging in the plug are immovable relative to each other, and the plug can be connected to a socket by pushing the pins 4, 5 into the female members of the socket by pressing the end face 25 of the socket 8.

Onskar man nu koppla isar stickproppen fran uttaget vrids kapan 8 relativt hylsan 7 via fattande i en darfor avsedd flans 26, sa att lasmedlet 24 overfors i °last !age. Fjaderorganet 22 kommer fortfarande att halla stickproppen i det i Fig 2 visade laget. Anbringas nu en tryckkraft pa kapans andyta 25, sasom visas genom pilen 27 i Fig 3, och denna tryckkraft är sa pass stor att den 20 formar overvinna fjaderorganets 22 fjaderkraft, da kommer kapan att forskjutas i riktningen enligt pilen 9 relativt hylsan 7 under skjutande av transmissionsdelen 16 framfor sig. Transmissionsdelens 16 kuggstanger 17, 18 kommer att bringa kugghjulen 15 hos hylsan att rotera, och dessa kommer att mata stiftbaskrop- pens kuggstang 14 i riktning motsatt pilen 9, sa att stiftbaskrop- pen kommer att skjutas mat i hylsan och darigenom hylsan att fungera som ett isarkopplingselement genom att trycka mot de honorganen omgivande ytorna for uttryckning av stiften 4, 5 ur honorganen genom alstrande av reaktionskrafter, sasom visas i Fig 3. If it is now desired to disconnect the plug from the socket, the cap 8 is rotated relative to the sleeve 7 via the socket in a flange 26 intended for this purpose, so that the welding agent 24 is transferred under load. The spring member 22 will still hold the plug in the layer shown in Fig. 2. If a compressive force is now applied to the end face 25 of the cap, as shown by the arrow 27 in Fig. 3, and this compressive force is so great that it forms overcomes the spring force of the spring member 22, then the cap will be displaced in the direction of the arrow 9 relative to the sleeve 7. the transmission part 16 in front of it. The racks 17, 18 of the transmission part 16 will cause the gears 15 of the sleeve to rotate, and these will feed the rack 14 of the pin base body in the direction opposite the arrow 9, so that the pin base body will be pushed food into the sleeve and thereby the sleeve to function as a ice coupling element by pressing against the surfaces surrounding the female means for pushing the pins 4, 5 out of the female means by generating reaction forces, as shown in Fig. 3.

Uppfinningen är givetvis inte pa n6got satt begransad till den ovan beskrivna utforingsformen, utan en mangd mojligheter till modifikationer darav torde vara uppenbara for en fackman pa omrklet utan att denne for den skull avviker fran uppfinningens ram sadan denna definieras i bifogade patentkrav. 9 537 6 Exempelvis yore det mojligt att utforma transmissionsinrattningen annorlunda och forse denna med ett langstrackt flexibelt organ, sasom en lina, och medel, sasom hjul utformade att omlanka det langstrackta organet for att astadkomma det rorelsemonster som ovan beskrivits mellan kapa, hylsa och stiftbaskropp vid isar- kopplingen av stickproppen fran ett uttag. The invention is of course not in any way limited to the embodiment described above, but a number of possibilities for modifications thereof should be obvious to a person skilled in the art without this deviating from the scope of the invention as defined in the appended claims. For example, it is possible to design the transmission device differently and to provide it with an elongate flexible member, such as a rope, and means, such as wheels designed to recirculate the elongate member to provide the motion pattern described above between the cap, sleeve and pin base. the connection of the plug from an outlet.
