Abstract

The invention relates to a connection or distribution piece for heatable hoses. The hose heating is carried out by means of heating conductors which are arranged running longitudinally in or on the hose wall. The connection piece consists of a connection element, inserted into the hose internal diameter, and insulation. According to the invention, the insulation is a sleeve tube (1), divided in the longitudinal axis, whose two half shells (11, 12) can be fixed on one another via connection means (111, 112, 121, 122), with the free ends (21) of the hoses (2) to be connected covered. On the outer surface of the connection element (3), there are integrally formed material steps (31, 32), increasing in thickness in the insertion direction, distributed on the circumference in the region of the insertion into the hose internal diameter (22). These material steps (31, 32) enter into a clamping effective connection with compression webs (113, 114, 123, 124) which are integrally formed on the inner circumference of the half shells (11, 12) when the hose (2) is retained on the connection element (3). <IMAGE>

Description

Oppfinnelsen gjelder et varmeisolert forbindelses- eller fordelerstykke for oppvarmbare slanger, som angitt i innledningen til patentkrav 1. The invention relates to a heat-insulated connection or distribution piece for heatable hoses, as stated in the introduction to patent claim 1.

Fra tysk bruksmønster 86 22 603.7 er det kjent en oppvarmbar slange, hvor det er anordnet en varmeleder i slangeveggen, parallelt med åpningen. Åpningen er anordnet forskjøvet sideveis til en side i forhold til slangeaksen, slik at det på den andre sida dannes en tverrsnittsøkning, hvor varmelederen er innleiret. Slangens veggområde mellom hulrommet og varmelederen er da tynnere i tverrsnitt enn veggområdet mellom varmelederen og slangens nærmeste overflate. A heatable hose is known from German utility model 86 22 603.7, where a heat conductor is arranged in the hose wall, parallel to the opening. The opening is arranged laterally shifted to one side in relation to the hose axis, so that on the other side a cross-sectional increase is formed, where the heat conductor is embedded. The wall area of the hose between the cavity and the heat conductor is then thinner in cross-section than the wall area between the heat conductor and the nearest surface of the hose.

Fra tysk bruksmønster 87 04 903.1 er det kjent et varmeisolert forbindelses- eller fordelerstykke for slike oppvarmbare slanger, som består av et forbindelseselement av varmeledende materiale, hvilket er delvis innsatt i slangeåpningen, samt en isolering. Varmelederen til de oppvarmbare slangene er blottlagt ved de frie endene ved fjerning av slangeveggen og blir lagt rundt de delområder av forbindelseselementet som rager utenfor slangenes hulrom. Et koplingsstykke for varmelederen er ført ut av dette området og kombinasjonen av de frie endene til slangeledningene som skal forbindes, med de delområdene av forbindelseselementene som rager ut av slangeledningene og varmeledeme som er omviklet om disse utragende delområdene av forbindelseselementet, er omsprøytet med en innkapsling av isolermateriale, som uløsbart blokkelement. Selv om det på denne måten dannes en tilfredsstillende forbindelse mellom oppvarmbare slanger med medoppvarming av forbindelseselementet, er tilvirkningen av en slik forbindelse omfattende og arbeidsintensiv, da forbindelsesstedet for slangene med elektroforbindelsen må innsettes i et besprøytningsverktøy og påsprøytes der med isolermateriale. From German utility model 87 04 903.1, a heat-insulated connection or distribution piece for such heatable hoses is known, which consists of a connection element of heat-conducting material, which is partially inserted into the hose opening, as well as an insulation. The heat conductor of the heatable hoses is exposed at the free ends when the hose wall is removed and is laid around the parts of the connecting element that protrude outside the hoses' cavity. A coupling piece for the heating conductor is led out of this area and the combination of the free ends of the hose lines to be connected, with the parts of the connecting elements that protrude from the hose lines and the heating element wrapped around these protruding parts of the connecting element, is sprayed with an encapsulation of insulating material, such as non-removable block element. Although in this way a satisfactory connection is formed between heatable hoses with co-heating of the connecting element, the manufacture of such a connection is extensive and labor-intensive, as the connection point for the hoses with the electrical connection must be inserted into a spraying tool and sprayed there with insulating material.

Hovedformålet med oppfinnelsen er å skape et forbindelses- eller fordelerstykke for oppvarmbare stykker, som på enkel måte skaper en tett og isolerende tildekning av forbindelsesstedet mellom slangestykkene. Dette kan i samsvar med oppfinnelsen oppnås ved å utforme forbindelses- eller fordelerstykket som angitt i den karakteriserende delen av patentkrav 1. The main purpose of the invention is to create a connection or distribution piece for heatable pieces, which in a simple way creates a tight and insulating covering of the connection point between the hose pieces. This can be achieved in accordance with the invention by designing the connecting or distributor piece as stated in the characterizing part of patent claim 1.

Det har herunder vist seg fordelaktig at det gjenstående innerrommet mellom halvskallene, slaveendene som skal forbindes, de delene av forbindelseselementene som rager ut av slangeåpningen og varmeledeme som er ført i halvskallenes indre, er oppfylt med en isolermasse. It has thus proved advantageous that the remaining inner space between the half-shells, the slave ends to be connected, the parts of the connecting elements that protrude from the hose opening and the heating element which is carried inside the half-shells, is filled with an insulating compound.

Forbindelsen mellom to slanger ved bruk av det nye forbindelses- eller fordelerstykke er meget enkel. Først blir forbindelseselementet ført inn i åpningen til to slanger som skal forbindes, ved deres frie ender. Disse slangeendene er behandlet slik, at varmeledeme ved de frie slangeendene er blottlagt ved fjerning av slangeveggen og forbundet elektrisk ledende med hverandre. Etter gjennomføringen av denne elektrisk ledende forbindelsen, som vanligvis er en loddeforbindelse, blir denne slangeforbindelsen lagt ned i det nedre halvskallet til det delte kapselrøret. Deretter blir det øvre halvskallet ført på plass på det nedre og dermed hele forbindelses- eller fordelerstykket lukket. Den isolerende innermassen kan føres inn i hulrommet i de to halvskallene før eller etter påsettingen. Isoleringen kan bestå av et skumbart materiale, som fyller det gjenstående innerrom og dermed danner ei kompakt isolerkappe. The connection between two hoses using the new connecting or distributor piece is very simple. First, the connecting element is inserted into the opening of two hoses to be connected, at their free ends. These hose ends are treated in such a way that the heating elements at the free hose ends are exposed when the hose wall is removed and electrically conductively connected to each other. After the completion of this electrically conductive connection, which is usually a solder connection, this hose connection is laid down in the lower half-shell of the split capsule tube. The upper half-shell is then brought into place on the lower one and thus the entire connecting or distributor piece is closed. The insulating inner mass can be fed into the cavity in the two half-shells before or after fitting. The insulation can consist of a foamable material, which fills the remaining inner space and thus forms a compact insulating jacket.

Som forbindelsesmiddel mellom de to halvskallene, kan det brukes sneppert-og/eller stikkelementer. Med slike forbindelsesmidler kan det oppnås en varig forbindelse innbyrdes mellom de to halvskallene, under innlukking av de enkelte forbindelseselementene til de oppvarmbare slangene. I tillegg til disse forbindelsesmidlene kan halvskallenes fri ender være utformet som ringklemmer, hvormed de omsluttete slangeområdene blir ytterligere holdt fast, slik at en uttrekking av disse slangeområdene fra de forbindelseselementene som er satt inn i slangeåpningene blir umulig. As a connecting means between the two half-shells, snap and/or plug elements can be used. With such connecting means, a permanent mutual connection can be achieved between the two half-shells, while enclosing the individual connecting elements of the heatable hoses. In addition to these connecting means, the free ends of the half-shells can be designed as ring clamps, with which the enclosed hose areas are further held firmly, so that extraction of these hose areas from the connecting elements inserted in the hose openings becomes impossible.

I tegningen er det vist skjematisk utførelseseksempler av forbindelses- og fordelerstykker i samsvar med oppfinnelsen, idet: fig. 1 viser et forbindelsesstykke for langsforbindelse av to slanger, mens fig. 2 viser et Y-formet forbindelses- eller fordelerstykke i lengdesnitt. The drawing shows schematic examples of connection and distributor pieces in accordance with the invention, in that: fig. 1 shows a connecting piece for longitudinal connection of two hoses, while fig. 2 shows a Y-shaped connecting or distributor piece in longitudinal section.

Fig. 1 viser i lengdesnitt et forbindelsesstykke for langsforbindelse av to slanger 2. I den viste gjengivelsen er bare det nedre halvskall 12 av kapperøret 1, som består Fig. 1 shows in longitudinal section a connecting piece for the longitudinal connection of two hoses 2. In the representation shown, only the lower half-shell 12 of the casing pipe 1, which consists of

av to halvskall, synlig. I dette halvskallet er de fri endene til slangene 2 innlagt, idet de på forhånd er blitt forbundet med hverandre over et forbindelseselement 3. Denne forbindelsen skjer på den måten, at forbindelseselementets 3 delområder blir satt inn i slangeendene. De delområder av forbindelseselementene 3 som blir innsatt i slangeåpningen er forsynt med materialavtrapninger 31, 32 som gjør det vanskeligere of two half-shells, visible. In this half-shell, the free ends of the hoses 2 are inserted, as they have previously been connected to each other via a connecting element 3. This connection takes place in such a way that the partial areas of the connecting element 3 are inserted into the hose ends. The partial areas of the connecting elements 3 which are inserted into the hose opening are provided with material step-offs 31, 32 which make it more difficult

å trekke slangeendene av forbindelseselementene 3. I halvskallet 12 er det i området ved de fri endene utformet trykkribber 123, 124, som ved innsettingen av slangeforbindelsen i halvskallet trer i klemmende inngrep med materialavtrapningene. På denne måten blir det fleksible slangeavsnitt som ligger over det innførte området av forbindelseselementet 3 i tillegg presset bak materialavtrapningene 31, 32 av trykkribbene 123, 124. to pull the hose ends from the connecting elements 3. In the half shell 12, pressure ribs 123, 124 are formed in the area of the free ends, which, when the hose connection is inserted into the half shell, enter into clamping engagement with the material tapers. In this way, the flexible hose section that lies above the inserted area of the connecting element 3 is additionally pressed behind the material tapers 31, 32 by the pressure ribs 123, 124.

På denne måten blir det dannet en tilnærmet uløsbar sperre for slangeenden på det innsatte området av forbindelseselementet 3. Som ekstra sikring er de fri endene av halvskallene utformet som ringklemmer 125, 126. På denne måten blir det ved bruk av kombinasjonsforbindelsen av de to slangeendene med forbindelseselementet 3 i halvskallet 12 i området ved ringklemmene 125, 126 oppnådd en avsperring, som ved påklipsing av det ikke viste halvskallet på halvskallet 12 oppnådd en ringformet avsperring av det indre i halvskallene. I dette innerrommet kan det før forbindelsen av de to halvskallene føres inn et rennbart isolermiddel, som etter sammenføyningen fyller ut fullstendig det innerrommet som blir igjen mellom halvskallene og slangeforbindelsene. Utflyting av isolermaterialet blir hindret av ringklemmene 125, 126. Isolermaterialet kan imidlertid også fylles inn etter sammenføyningen av de to halvskallene gjennom en hensiktsmessig fyllåpning. Det kan dreie seg om et skumbart isolermateriale, som etter oppskummingen også fyller fyllåpningen tett og isolerende. In this way, an almost unremovable barrier is formed for the hose end on the inserted area of the connection element 3. As an additional safeguard, the free ends of the half-shells are designed as ring clamps 125, 126. In this way, when using the combination connection of the two hose ends with the connecting element 3 in the half-shell 12 in the area of the ring clamps 125, 126 achieved a barrier, which by clipping the half-shell, not shown, on the half-shell 12 achieved a ring-shaped barrier of the interior of the half-shells. In this inner space, before the connection of the two half-shells, a flowable insulating agent can be introduced, which, after joining, completely fills the inner space that remains between the half-shells and the hose connections. Flowing of the insulating material is prevented by the ring clamps 125, 126. However, the insulating material can also be filled in after joining the two half-shells through a suitable filling opening. It may be a foamable insulating material, which after foaming also fills the filling opening tightly and insulatingly.

Forut for sammensetningen av de to halvskallene må de to varmetrådene 23, 24 forbindes elektrisk, fortrinnsvis med en loddeforbindelse 231. Prior to the assembly of the two half-shells, the two heating wires 23, 24 must be connected electrically, preferably with a solder connection 231.

Det er allerede nevnt at i fig. 1 er bare det nedre halvskallet vist. Det øvre halvskallet er utformet speilbilledlig til det første og blir sammenføyd med It has already been mentioned that in fig. 1, only the lower half shell is shown. The upper half-shell is designed as a mirror image of the first and is joined with

forbindelsesmidler 111, 112 til forbindelsesmidler 121, 122 på det nedre halvskallet 12. Forbindelsesmidlene 121 kan være stikkåpninger 121 for innføring av tilsvarende stikkstifter som er plassert på tilsvarende sted på det andre halvskallet. På det nedre halvskallet 12 er det anordnet tre slike stikkåpninger 121 fordelt over lengden, mens det er plassert motstående stikkstifter 122 med tilsvarende plassering. De tilsvarende forbindelsesmidlene er altså anordnet på motstående sider av de andre halvskallet. connecting means 111, 112 to connecting means 121, 122 on the lower half-shell 12. The connecting means 121 can be plug openings 121 for inserting corresponding plug pins which are placed in a corresponding place on the other half-shell. On the lower half-shell 12, there are arranged three such plug openings 121 distributed over the length, while opposite plug pins 122 are placed with corresponding placement. The corresponding connecting means are therefore arranged on opposite sides of the other half-shells.

Det i fig. 2 viste Y-formete forbindelses- eller fordelerstykket er illustrert i samme gjengivelse som fordelerstykket i fig. 1. Et nedre halvskall 12 har en hoveddel 127 og to grendeler 128, 129 som rager ut i Y-form. Disse enkeltdelene 127, 128, 129 har samme innvendige utforming som de rette forbindelsesdelene i fig. 1. Samme trekk har her fått samme henvisningstall. Slangene 2 som er holdt fast i grendelen 128, 129 har hver en varmetråd 23, 24 som over loddeforbindelser 231, 241 står i forbindelse med tråder 25, 26. That in fig. The Y-shaped connecting or distributor piece shown in 2 is illustrated in the same rendering as the distributor piece in fig. 1. A lower half-shell 12 has a main part 127 and two branch parts 128, 129 which protrude in a Y shape. These individual parts 127, 128, 129 have the same internal design as the straight connecting parts in fig. 1. Here, the same feature has been given the same reference number. The hoses 2 which are held firmly in the branch part 128, 129 each have a heating wire 23, 24 which is connected to wires 25, 26 via solder connections 231, 241.

Sammenføyningen av de to halvskallene skjer på samme måte som beskrevet i forbindelse med fig. 1. Også oppfyllingen av de åpne rommene i halvskallene skjer på samme måte. The joining of the two half-shells takes place in the same way as described in connection with fig. 1. The open spaces in the half-shells are also filled in the same way.
