Abstract

A bushing for use in terminating the ends of electrical conductors has a hollow metal end piece 1 for mounting in terminal strips and electrical terminals, and on which there is a plastic collar 3 with a projecting flange formed on the top side 5 as a badge 4 for an identification sign for the conductor 2. The bushings are made from tape 11, which is rolled up, and when suspended at one axle 13, the bushings can be moved forward and the identification signs can be written on the top side 5 of the badge 4 with existing or easily modified plotters 15, after which the bushing is mounted by existing methods. This saves work time in placing the identification sign on the conductor, or one can avoid costly special equipment for marking of the conductor. <IMAGE>

TEKNIKKENS STANDPUNKTBACKGROUND OF THE ART

Flere steder er det blevet et lovkrav at ledningsopmærke el-tavler, blandt andet ifølge standarden EN 60204-1. Det betyder, at alle ledninger skal mærkes med egne identifikationstegn i forbindelse med montagen i klemrækker og lignende. I større systemer 5 anvendes typisk tal med 1-6 cifre eller mere som identifikation. Mærkningen betyder en væsentlig øget montagetid foruden omkostninger til tegnbærere.In several places, it has become a legal requirement to mark wiring boards, among other things according to the standard EN 60204-1. This means that all wires must be marked with their own identification signs in connection with mounting in terminal blocks and the like. In larger systems 5, numbers with 1-6 digits or more are typically used for identification. The marking means a significant increase in assembly time in addition to the cost of character bearers.

Opfindelsen angår tyller til endemontering på elektriske ledere, især isolerede kobberledninger, hvor hver tylle omfatter et hult, metallisk endestykke, der er forsynet med 10 en krave af kunststof med en udragende flange, der er støbt integreret med kraven og udformet som et skilt, der kan påføres identifikationstegn for ledningen.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to tethering ends for electrical conductors, in particular insulated copper wires, each tulle comprising a hollow metallic end piece provided with a plastic collar with a protruding flange molded integrally with the collar and formed as a sign which may be affixed to identification wire for the cord.

Endvidere angår opfindelsen en fremgangsmåde til påføring af identifikationstegn på tyller til endemontering på elektriske ledere, især isolerede kobberledninger, og som IS omfatter et hult, metallisk endestykke forsynet med en krave af kunststof med en udragende flange med et skilt, der påføres identifikationstegn for ledningen.Furthermore, the invention relates to a method for applying identification marks to tulle for end mounting on electrical conductors, in particular insulated copper wires, and which IS comprises a hollow metallic end piece provided with a plastic collar with a protruding flange with a sign affixed to the identification mark.

Sådanne tyller er kendt fra DE 40 09 229 Cl og DE 42 38 370 Al. Tyllerne heri sprøjtestøbes i flade ark. Her spares montagetid, fordi man forinden montering kan 20 påskrive identifikationstegn på skiltene, f.eks. med en elektronisk plotter, der kan være styret af et CAD-anlæg. Tilbage står at knække skiltene af og montere dem. På grund af plotteren skal påføring af tegnene ske centralt, og der kan i en større produktion være problemer med at adskille og genkende de enkelte ark.Such tulle is known from DE 40 09 229 CI and DE 42 38 370 A1. The tufts herein are injection molded into flat sheets. Here, the installation time is saved because prior to mounting, 20 identification signs can be inscribed on the signs, e.g. with an electronic plotter that can be controlled by a CAD system. Remaining stands are to break the signs and mount them. Because of the plotter, the characters must be applied centrally, and in larger production there may be problems separating and recognizing the individual sheets.

25 Fra DE 31 53 235 C2 kendes fremstilling af kabelsko i sammenhængende bånd, der kan rulles op. Kabelskoene er fremstillet i korte bånd, der gøres til endeløse bånd ved sammenklemning af særlige forbindelseselementer. Skriftet omtaler ikke identifikationstegn til kabelskoene eller påføring af identifikationstegn.25 From DE 31 53 235 C2 it is known to manufacture cable lugs in cohesive bands that can be rolled up. The cable shoes are made in short strips which are made into endless strips by squeezing special connecting elements. The script does not mention identification signs for the cable shoes or the application of identification signs.

30 Fra anden side kendes en metode, der består i at påføre identifikationstegnene direkte på ledningerne med en inkjet printer, idet hver ledning blot føres gennem printeren.30 On the other hand, a method consists of applying the identification characters directly to the wires with an inkjet printer, each wire passing through the printer only.

Tyllen sættes på manuelt og uafhængigt heraf. Printeren er imidlertid kostbar, og da DK PR 172490 B1 2 det er nødvendigt med en printer for hver montør, fordi man ikke på forhånd kender hver lednings længde, er denne metode kun økonomisk ved produktion i store serier.The tulle is mounted manually and independently. However, the printer is expensive and since DK PR 172490 B1 2 requires a printer for each installer because you do not know the length of each wire in advance, this method is only economical for large series production.

Endvidere kendes en tylle med en flange, der strækker sig fra kraven og i retning mod-5 sat endestykket. Yderst har flangen en modhage. Først sættes tyllen på den afisolerede ledningsende, og tyllen sammenklemmes. Herved kommer flangen til at strække sig ned langs ledningen. Mærkning foretages manuelt med en tang, idet man fra en bakke med tegnbærere af form som sammentrykte ringe tager en tegnbærer for hvert ciffer og skubber den ind over modhagen på flangen. Det dannede identifikationstegn be-10 stemmes af en forskrift i form af et ledningsdiagram eller lignende, som montøren skal aflæse. Foruden tidsforbruget ved mærkningen har denne kendte metode også den ulempe, at flangen kan brække under monteringen.Furthermore, a tulle with a flange extending from the collar and in the direction opposite to the end piece is known. Extremely, the flange has a barbs. First, the tulle is put on the stripped wire end and the tulle is squeezed. This causes the flange to extend down the line. Marking is done manually with a pair of pliers, taking from a tray of character carriers of the form as compressed rings a character carrier for each digit and pushing it over the counter bar on the flange. The identification mark formed is determined by a regulation in the form of a wiring diagram or the like, which the installer must read. In addition to the time spent on marking, this known method also has the disadvantage that the flange can break during mounting.

En fjerde kendt løsning på mærkningsproblemet består i en maskine med handelsnav· 15 net LOTZE-LSC, der både kan skrive identifikationstegn på hver ledning og påsætte tyller. Maskinen er imidlertid ekstremt kostbar og vil være uøkonomisk i mindre produktionsvirksomheder.A fourth known solution to the labeling problem consists of a machine with a trade name · 15 net LOTZE-LSC, which can both write identification marks on each wire and apply tulle. However, the machine is extremely expensive and will be uneconomical in smaller production companies.

FORDELE VED OPFINDELSENBENEFITS OF THE INVENTION

20 Hovedformålet med opfindelsen at undgå eller formindske ulemperne ved de kendte mærkningsmetoder, især ved at spare den arbejdsproces at adskille tyller fremstillet i ark og fremfinde tyller med de foreskrevne numre, og at kunne fremføre tyllerne til automatisk montering.The main object of the invention is to avoid or reduce the disadvantages of the known marking methods, in particular by saving the working process of separating tulle made in sheets and finding tulle with the prescribed numbers and being able to carry the tulle for automatic mounting.

25 Det opnås ifølge opfindelsen ved tyller af den i indledningen angivne art, hvor tyllerne er fremstillet indbyrdes sammenhængende som bøjelige bånd. På den måde kan påsætningen af tyllerne ske med i princippet samme redskaber, som kendes ved påsætning af tyller uden flanger, idet tyllebåndet føres ind i håndtaget på et manuelt afisole-rings- og tyllepåsætningsværktøj. Ved den forudgående påskrift af identifikationsteg-30 nene kan der tages hensyn til monteringsrækkefølgen, således at der ikke skal bruges tid til at finde tyllen med det korrekte nummer til den pågældende ledning. Monte- DK PR 172490 B1 3 ringsrækkefølgen kan eventuelt tages som en fil fra et CAD-anlæg og derfra sendes til en plotter.It is obtained according to the invention by tulle of the kind specified in the preamble, where the tulle is made interconnected as flexible bands. In this way, the application of the tulle can be carried out in principle with the same tools as are known by the application of tulle without flanges, as the tire belt is inserted into the handle of a manual de-insulation and tulle application tool. In the previous inscription of the identification signs, the mounting order can be taken into account, so that no time is needed to find the tulle with the correct number for the line in question. The Monte PR 172490 B1 3 order can be taken as a file from a CAD system and then sent to a plotter.

Det særlige ved fremgangsmåden ifølge opfindelsen er, at tyllerne fremstilles i endelø-5 se bånd, som derefter monteres i et magasin indeholdende mindst ét bånd, hvorefter båndet med tyller fremføres trinvis i afhængighed af et styresystem til et skriveapparat, der påfører identifikationstegnene. Derved kan båndet udnyttes til en fortløbende nummerering af tyllemes skilte, der hænger sammen, og man undgår således at have flere ark. Man undgår også senere at skulle skille arkene fra hinanden, og tyllebåndet 10 kan fremføres til automatiske monteringsprocesser.The special feature of the method according to the invention is that the tulle is produced in endless tape which is then mounted in a magazine containing at least one tape, after which the tape with tulle is advanced stepwise in dependence on a control system for a typewriter which applies the identification characters. In this way, the tape can be utilized for continuous numbering of the tulle signs that are interconnected, thus avoiding having multiple sheets. It is also later avoided to separate the sheets, and the tape 10 can be fed into automatic mounting processes.

TEGNINGENDRAWINGS

Udførelsesformer for opfindelsen skal herefter beskrives nærmere under henvisning til tegningen, hvor 15 fig. 1 viser en del af et endeløst bånd af tyller ifølge opfindelsen set fra oven, fig. 2 viser en tylle ifølge opfindelsen set fra siden og monteret på en ledning, fig. 3 viser tyllen ifølge fig. 2 set efter linien ΙΠ-ΙΙΙ, og fig. 4 viser i princippet et system til brug ved en fremgangsmåde ifølge opfindelsen 20 til påføring af identifikationstegn på tyllerne.Embodiments of the invention will now be described in more detail with reference to the drawing, in which: FIG. 1 is a plan view of a portion of an endless band of tulle according to the invention; FIG. 2 shows a side view of a tulle according to the invention and mounted on a conduit; FIG. 3 shows the tulle of FIG. 2 taken along line ΙΠ-ΙΙΙ, and FIG. 4 shows in principle a system for use in a method according to the invention 20 for applying identification marks to the tulle.

BESKRIVELSE AF UDFØRELSESEKSEMPLERDESCRIPTION OF EXAMPLES EXAMPLES

Ved fremgangsmåden ifølge opfindelsen som vist i eksemplet på fig. 4 kan milerne 12 DK PR 172490 B1 4 hænges op i et magasin, for eksempel på en aksel 13, og derfra føres til et skriveapparat 15 for påføring af tal og bogstaver med en eksisterende penplotter, der er forholdsvis billig i anskaffelse, idet et afsnit af båndet 11 føres ind i plotterens arbejdsområde 17 med skiltene 4 vendende opad. Fremføringen kan ske med et tandhjul 19, 5 der griber ind i tyllebåndet 11. Fremføring og skrivning af identifikationstegn kan styres af elektronisk med et EDB-anlæg 21.1 større produktioner kan ruller med tyller i forskellig dimension ophænges ved siden af hinanden i magasinet, og derefter fødes til en plotter styret af et CAD-anlæg, for eksempel af mærket EplanO.In the method of the invention as shown in the example of FIG. 4, the miles 12 may be hung in a magazine, for example, on a shaft 13, and from there be fed to a typewriter 15 for applying numbers and letters with an existing pen plotter which is relatively inexpensive to acquire, a section of the band 11 is inserted into the working area 17 of the plotter with the signs 4 facing up. The feed can be carried out with a sprocket 19, 5 which engages the belt 11. The feeding and writing of identification characters can be controlled electronically with a computer system 21.1 larger productions, rolls with tulle of different dimensions can be hung side by side in the magazine, and then is fed to a plotter controlled by a CAD system, for example by the EplanO brand.

10 Indenfor opfindelsens rammer er det også muligt på ikke vist måde at oplagre tyllebåndene 11 i kasseformede magasiner, der erstatter de akselmonterede ruller 12 på fig.10 Within the scope of the invention, it is also possible, in a manner not shown, to store the tapes 11 in box-shaped magazines which replace the shaft mounted rollers 12 in FIG.

4. Båndene lægges i magasinerne i mæanderform lige som endeløse papirbaner til EDB-printere eller patronbælter til maskingeværer. I en yderligere udførelsesform for opfindelsen vil man eventuelt kunne have en lille håndbåren plotter, der kan skrive på 15 et stykke bånd med tyller, og som kan afisolere og crimpe.4. The ribbons are placed in magazines in magazines like endless paper webs for computer printers or cartridge belts for machine guns. In a further embodiment of the invention, one may optionally have a small hand-carried plotter capable of writing on a piece of ribbon with tulle, which can be stripped and crimped.

Tyller med skilte ifølge opfindelsen vil kunne leveres som fortløbende nummerede, for eksempel fra 1 til 1000, eller numrene kan direkte overføres fra CAD-anlæg så det passer med ledningsdiagrammer i den for montagen mest hensigtsmæssige rækkeføl-20 ge.Shelves with signs according to the invention can be delivered as consecutive numbers, for example from 1 to 1000, or the numbers can be directly transferred from CAD systems to fit wiring diagrams in the most convenient order for installation.

Herefter vil det være muligt at montere tyllen 6 med et håndværktøj, der fungerer efter kendte principper, som i en tang af mærket Stripax© fra firmaet Weidmii lier til montering af tyller uden flanger. Her vil båndet 11 kunne fødes ind gennem værktøjets 25 håndtag og monteres på kendt måde. Endvidere er der mulighed for anvendelse af de båndmonterede tyller 6 i modificerede udgaver af automatiske tyllemonteringsapparater, eksempelvis af fabrikatet Phoenix Contact.Then it will be possible to mount the tulle 6 with a hand tool that works according to known principles, such as in a pliers of the brand Stripax © from the company Weidmii lier for mounting tulle without flanges. Here, the belt 11 can be fed through the handle 25 of the tool and mounted in a known manner. Furthermore, it is possible to use the belt mounted tulle 6 in modified versions of automatic tulle mounting devices, for example by the Phoenix Contact manufacturer.

Andre udførelsesformer er mulige indenfor kravenes omfang, herunder at lade en ma-30 skine både foretage automatisk mærkning af skilte på tyller med påfølgende afisole-ring og crimpning af tyllerne på ledninger. Endvidere er det muligt, som ved den kendte teknik, at lave dobbelttyller med skilteflanger, det vil sige tyller med plads til to ledningsender i hver tylle.Other embodiments are possible within the scope of the claims, including allowing a machine to both automatically mark signs on tulle with subsequent de-insulation and crimp the tulle on wires.
