Opfindelsen angår en elektrisk forbindelsesklemme med en oplukkelig strømbane med to indbyrdes flugtende stangformede ledere, som er omgivet af hver sin rotationssymmetriske isolator, samt en kontaktindretning, som forbinder disse ledere, og som er udformet til udligning 5 af flugtningsafvigelser mellem de stangformede ledere, hvor der forefindes et mellemrum mellem de to isolatorer.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an electrical connection terminal with an openable circuit with two mutually-integral rod-shaped conductors surrounded by rotationally symmetrical insulators, and a contact device connecting these conductors, which is designed to compensate for anomalous deviations between the rod-shaped conductors where there is a gap between the two insulators.
En forbindelsesklemme af denne art er kendt fra FR-offentliggørel-sesskrift 2.096.734. Det omtalte mellemrum mellem de to isolatorer er i den forbindelse åbent i radial retning. Ved denne udsættes isolations-10 mediet, fx. atmosfærisk luft, for en påvirkning p.gr. af det elektriske felt, som udgår fra lederne, som skal forbindes.A connector terminal of this kind is known from FR Publication No. 2,096,734. In this connection, the said gap between the two insulators is open in the radial direction. By this, the insulating medium is exposed, e.g. atmospheric air, for an impact p.gr. of the electrical field emanating from the conductors to be connected.
Det er opfindelsens opgave at reducere denne påvirkning af isolationsmediet.It is the object of the invention to reduce this effect on the insulation medium.
Ifølge opfindelsen løses den stillede opgave ved, at begge isola-15 torer på mindst en del af deres længde er omsluttet af en fælles manchet af elastisk isolationsmateriale, som dækker mellemrummet, og som på højde med mellemrummet er forsynet med en omløbende vulst, som er udformet med et hulrum med åbning mod mellemrummet, og at de mod hinanden vendende endeflader på isolatorerne samt overfladen af hulrummet i 20 manchetten på i og for sig kendt måde er elektrisk ledende og står i elektrisk ledende forbindelse både indbyrdes og med lederne.According to the invention, the task is solved by the fact that both insulators, at least part of their length, are enclosed by a common sleeve of elastic insulating material which covers the gap and is provided with a circumferential bead which is at the same height as the gap. formed with a gap opening to the gap, and that the facing end faces of the insulators and the surface of the cavity of the cuff in a manner known per se are electrically conductive and are in electrically conductive connection both mutually and with the conductors.
Ved forbindelsesklemmen ifølge opfindelsen befinder de stangformede ledere og de mod disse ledere vendende indersider af manchetterne sig på samme elektriske potentiale, hvorved det opnås, at det i hulrum-25 met tilstedeværende elektriske isolationsmateriale ikke påvirkes dielektrisk.In the connection terminal of the invention, the rod-shaped conductors and the inner faces of the cuffs are at the same electrical potential, whereby the electrical insulating material present in the cavity is not obtained dielectric.
Hver isolator kan i den endeflade, som afgrænser mellemrummet, have en central fordybning, som er udformet til optagelse af den tilstødende del af kontaktindretningen. Denne udformning gør det muligt, at 30 afstanden mellem isolatorerne kan vælges mindre og letter dette ved, at den til hindring af giimudladninger anbragte ledende belægning anbringes med lille afstand fra lederne.Each insulator may have a central recess formed in the end surface defining the gap to accommodate the adjacent portion of the contact device. This design allows the distance between the insulators to be chosen less and facilitates this by placing the conductive coating arranged to prevent gaseous discharges at a small distance from the conductors.
Isolatorerne kan hver have form som to keglestumper, som med sine største grundflader vender mod hinanden. På denne måde får både de ud-35 vendige ender af forbindelsesklemmen og de til modtagelse af manchetten - 2 -The insulators can each take the form of two conical blocks facing each other with their largest ground faces. In this way, both the outer ends of the connector clip and those for receiving the cuff - 2

anbragte omkredsflader en hensigtsmæssig form. I denne sammenhæng kan det anbefales at dimensionere manchetten således, at den strækker sig omtrent fra den største diameter på den ene isolator til den største diameter på den anden isolator.placed circumferential surfaces in an appropriate shape. In this context, it is recommended to dimension the cuff so that it extends approximately from the largest diameter of one insulator to the largest diameter of the other insulator.
5 Hver isolator har en omløbende metallisk flange, som griber om kring den tilhørende frie endeflade på manchetten, og som i den tilhørende isolator ender i et elastisk, elektrisk ledende lag, som er anbragt spaltefrit i isolatoren. Dermed danner flangerne en anlægsflade for manchetten, som på denne måde tvinges til berøring med dele, som 10 befinder sig på jordpotentialet. I denné forbindelse er det hensigtsmæssigt, hvis den ydre kappeflade på manchetten er elektrisk ledende og står i elektrisk ledende forbindelse med de jordforbundne flanger.Each insulator has a circumferential metallic flange which engages around the associated free end face of the cuff and which ends in the associated insulator in an elastic, electrically conductive layer which is slit-free in the insulator. Thus, the flanges form a contact surface for the cuff which in this way is forced into contact with parts which are at the ground potential. In this connection, it is appropriate if the outer casing surface of the cuff is electrically conductive and is in electrically conductive connection with the grounded flanges.
Dermed får hele den udvendige flade af manchetten jordpotentiale og bliver således berøringssikker.Thus, the entire outer surface of the cuff gains ground potential and thus becomes touch-safe.
15 Manchetten kan ved mellemrummet mellem isolatorerne ende i to læ ber, som hver flugter med en endeflade i den tilgrænsende isolator, som · afgrænser mellemrummet, og det elektrisk ledende lag på overfladen af manchettens hulrum og på isolatorernes mod hinanden vendende endeflader fortsætter til til tilgrænsende kappeflader på de pågældende dele.At the gap between the insulators, the cuff may end in two lips, each flush with an end surface of the adjacent insulator which delimits the gap, and the electrically conductive layer on the surface of the cuff cavity and on the facing faces of the insulators continues to adjoin. sheath surfaces on the parts in question.
20 Dermed sikres en god elektrisk forbindelse af den ledende belægning på overfladen af hulrummet og indersiden af manchetten.20 Thus, a good electrical connection is ensured by the conductive coating on the surface of the cavity and the inside of the cuff.
På tegningen er et udførelseseksempel for opfindelsen vist rent skematisk i et lodret snitbillede.In the drawing, an embodiment of the invention is shown schematically in a vertical sectional view.
På tegningen betegnes med 1 henholdsvis 2 to indbyrdes flugtende 25 ledere, som danner en oplukkelig strømbane. Lederne 1, 2 er forbundet ved hjælp af en kontaktindretning, som er udformet til udligning af flugtningsafvigelser for lederne 1, 2, og som består af kontaktlameller 3 samt af ringfjedre 4, som omslutter kontaktlamellerne 3.In the drawing, 1 and 2 are respectively mutually flush conductors, which form an openable circuit. The conductors 1, 2 are connected by means of a contact device designed to equalize the deviation deviations of the conductors 1, 2, consisting of contact slats 3 and of ring springs 4 which surround the contact slats 3.
Lederne 1, 2 er hver omsluttet af en rotationssymmetrisk elektrisk 30 isolator 5, fx. af duroplastisk formstof, som indeholder fyldstoffer. Isolatorerne 5 er ens. Mellem de mod hinanden vendende endeflader på isolatorerne 5 findes et mellemrum 6 til opfangning af produktionstolerancer og varmeudvidelser. Også de mod hinanden vendende ender af lederne 1, 2 holdes til udligning af produktionstolerancer og varmeudvi-35 delser i en afstand, for hvilken der på tegningen ikke er indføjet no- - 3 -The conductors 1, 2 are each enclosed by a rotationally symmetrical electrical insulator 5, e.g. of duroplastic resin containing filler. The insulators 5 are similar. Between the facing end faces of the insulators 5 there is a gap 6 for intercepting production tolerances and heat expansions. Also, the opposite ends of the conductors 1, 2 are held to equalize production tolerances and heat extensions at a distance for which no drawing is inserted in the drawing.

I de mod hinanden vendende endeflader af isolatorerne 5 findes der i hver en koncentrisk fordybning 5a, som er udformet til optagelse af det tilhørende afsnit af kontaktindretning 3, 4.In the opposite end faces of the insulators 5 there is in each a concentric recess 5a which is designed to receive the associated section of contact device 3, 4.
5 På hensigtsmæssig måde har isolatorerne 5 hver form som to kegle stumper, som er anbragt med deres største diametre mod hinanden.5 Conveniently, the insulators 5 each have the shape of two cone pieces arranged with their largest diameters facing each other.
På mindst en del af deres længde er begge isolatorer 5 omsluttet af en for dem begge fælles manchet 7 af elastisk isolationsstof, som ligger tæt an mod yderfladerne på isolatorerne 5 og dækker mellemrummet 10 6. Manchetten 7 strækker sig i det viste eksempel omtrent fra den største diameter på den ene isolator 5 til den største diameter på den anden isolator 5.At least a portion of their length, both insulators 5 are enclosed by one elastic insulator fabric cuff 7, which is adjacent to the outer surfaces of the insulators 5 and covers the gap 10 6. In the example shown, the sleeve 7 extends approximately from the largest diameter of one insulator 5 to the largest diameter of the other insulator 5.
På højde med mellemrummet 6 er manchetten 7 forsynet med en omløbende vulst 7a, som omslutter et mod mellemrummet 6 åbent hulrum 7b.At the height of the gap 6, the sleeve 7 is provided with a circumferential bead 7a which encloses a cavity 7b which is open to the gap 6.
15 Ved hjælp af vulsten 7a og hulrummet 7b kan grove flugtningsafvi- gelser mellem lederne 1, 2 let udlignes af manchetten 7.15 By means of the bead 7a and the cavity 7b, coarse deviation between the conductors 1, 2 can be easily offset by the cuff 7.
Til undgåelse af glimudladninger inden i mellemrummet 6 og hulrummet 7b er endefladerne på isolatorerne 5, inklusive deres fordybninger 5a og desuden også overfladerne i hulrummet 7b elektrisk ledende. De 20 elektrisk ledende flader står i elektrisk ledende forbindelse både indbyrdes og med lederne 1, 2.To avoid glare discharges within the gap 6 and the cavity 7b, the end faces of the insulators 5, including their recesses 5a and, additionally, the surfaces of the cavity 7b are electrically conductive. The 20 electrically conductive faces are in electrically conductive connection both mutually and with conductors 1, 2.
I det viste eksempel løber manchetten mod mellemrummet 6 i to læber 7c, som hver flugter med en endeflade på en isolator 5, der afgrænser mellemrummet 6. Med denne udformning åbnes mulighed for en elek-25 trisk ledende forbindelse mellem den elektrisk ledende overflade i hulrummet 7b og de tilhørende endeflader på isolatorerne 5. Denne elektrisk ledende forbindelse frembringes ved, at den elektriske ledningsevne for de nævnte overflader fortsættes indtil et tilgrænsende endeafsnit på den indre kappeflade i manchetten 7 og til et tilgrænsende 30 endeafsnit på kappefladen på hver isolator 5. Med denne udformning ligger de ledende endeafsnit på kappefladen i manchetten 7 og de ledende afsnit af kappefladen på isolatorerne 5 i tæt elektrisk kontakt med hinanden.In the example shown, the sleeve runs toward the gap 6 in two lips 7c, each flush with an end face of an insulator 5, which defines the gap 6. This design allows for an electrically conductive connection between the electrically conductive surface of the cavity. 7b and the associated end faces of the insulators 5. This electrically conductive connection is produced by continuing the electrical conductivity of said surfaces to an adjacent end portion of the inner casing surface of the cuff 7 and to an adjacent 30 end portion of the casing surface of each insulator 5. With in this embodiment, the conductive end portions of the casing surface of the sleeve 7 and the conductive portions of the casing surface of the insulators 5 are in close electrical contact with each other.
Til indbygning af indretningen, fx. i (stiplet viste) vægge 8 i et 35 elektrisk koblingsfelt eller lignende, er hver isolator 5 forsynet med - 4 -For incorporating the device, e.g. in (dotted) walls 8 in an electrical electrical field or the like, each insulator 5 is provided with - 4 -

5 For at muliggøre jording af indretningen er den ydre kappeflade på manchetten 7 ligeledes elektrisk ledende og står i elektrisk ledende forbindelse med flangerne 9.5 To enable grounding of the device, the outer casing surface of the sleeve 7 is also electrically conductive and is electrically conductive to the flanges 9.
