Description

Denne oppfinnelse angår elektriske kontaktinnretninger This invention relates to electrical contact devices

og er spesielt rettet mot en slik innretning som er egnet til skjøting av tilsvarende tråder i ledningspar. and is particularly aimed at such a device which is suitable for splicing corresponding wires in wire pairs.

Det er ofte nødvendig å skjøte tilsvarende ledninger i bunter av ledningspar, f.eks. i telefonkabler, og i betraktning av det store antall individuelle forbindelser (ofte flere tusen) som skal foretas er det viktig at hver forbindelse kan utføres så raskt som mulig under anvendelse av halvautomatisk verktøy eller apparatur. Det er også viktig at det totale volum av for-bindelsene blir så lite som mulig på grunn av den begrensede plass som er tilgjengelig i mannhull eller lignende. It is often necessary to splice corresponding wires into bundles of wire pairs, e.g. in telephone cables, and in view of the large number of individual connections (often several thousand) to be made, it is important that each connection can be made as quickly as possible using semi-automatic tools or equipment. It is also important that the total volume of the connections be as small as possible due to the limited space available in manholes or the like.

Det er et formål med denne oppfinnelse å tilveiebringe It is an object of this invention to provide

en elektrisk kontaktinnretning som tilfredsstiller de ovenfor angitte krav og som spesielt er egnet for bruk sammen med det halv-automatiske ledningstilkoplingsapparat som er beskrevet i US-patent 3.975.812. I dette apparat blir kontaktinnretninger på-montert en fleksibel bærestrimmel og matet til ledningsinnførings-stasjoner på hver side av strimmelen, hvor innføringsstemplet skyver ledningene inn i klemmeslisser i kontaktinnretningen. For å kunne foreta de mange tusen tilkoblinger som skal gjøres (f .eks. mellom telefonkabler) så hurtig som mulig, er det vektig at ledningene krever så lite manipulering som mulig av installatøren forut for tilkoblingen ved hjelp av det nevnte apparat. Dette blir oppnådd ved anvendelse av kontaktinnretningen ifølge forelig-gende oppfinnelse. Som det vil fremgå anbringes klemmene rygg mot rygg med de langsgående vegger eller kanter som danner klemmenes slisser, liggende i et plan som inneholder bærestrimmelens frem-matningsretning, mens de nevnte kanter strekker seg vinkelrett på denne retning. an electrical contact device which satisfies the above stated requirements and which is particularly suitable for use together with the semi-automatic wire connection apparatus described in US patent 3,975,812. In this apparatus, contact devices are mounted on a flexible carrier strip and fed to wire insertion stations on either side of the strip, where the insertion plunger pushes the wires into clamping slots in the contact device. In order to be able to make the many thousands of connections to be made (e.g. between telephone cables) as quickly as possible, it is important that the cables require as little manipulation as possible by the installer prior to the connection using the aforementioned device. This is achieved by using the contact device according to the present invention. As will be seen, the clamps are placed back to back with the longitudinal walls or edges which form the slits of the clamps, lying in a plane containing the forward direction of the carrier strip, while the said edges extend perpendicular to this direction.

I tilknytning til ovenstående skal det imidlertid be-merkes at den her angitte nye kontaktinnretning også er anvendbar i andre forbindelser enn ved strimmelmatning som beskrevet. In connection with the above, however, it should be noted that the new contact device specified here can also be used in other connections than with strip feeding as described.

Nærmere bestemt angår således denne oppfinnelse en elektrisk kontaktinnretning omfattende et isolerende hus som danner klemmeopptagende hulrom med åpninger til motsatte ender av huset, i hvert av hvilke hulrom det er anbragt en elektrisk klemme som hver er stanset ut og tildannet som ett enkelt stykke metallplatemateriale og har første og andre parallelle ledningsmottagende slisser i sideveis avstand fra hverandre og med munninger rettet mot vedkommende hulromsåpning slik at klemmene vender i motsatte retninger bort fra hverandre. More specifically, this invention thus relates to an electrical contact device comprising an insulating housing which forms clamp-receiving cavities with openings to opposite ends of the housing, in each of which cavities an electrical clamp is placed, each of which is punched out and formed as a single piece of sheet metal material and has first and second parallel wire-receiving slots laterally spaced from each other and with mouths directed towards the relevant cavity opening so that the clamps face in opposite directions away from each other.

Det er imidlertid en ulempe ved slike innretninger at det opptrer vanskeligheter ved manipulering og plassering av begge tilsvarende ledninger i de ledningspar som skal tilkobles, da det under tilkoblingsoperasjonen foreligger risiko for at de første ledninger forskyves fra slissene før de andre ledninger tilkobles, eller det er nødvendig å anvende kamlignende jigger for å fastholde begge ledningspar slik at de kan tilkobles samtidig. However, it is a disadvantage of such devices that difficulties arise when manipulating and placing both corresponding wires in the pairs of wires to be connected, as during the connection operation there is a risk that the first wires are displaced from the slots before the other wires are connected, or there is necessary to use comb-like jigs to hold both wire pairs so that they can be connected at the same time.

I en kontaktinnretning som er kjent fra US-patent 3.406.247, ligger veggene eller kantene av ledningsslissene i et plan vinkelrett på kontaktinnretningenes matningsretning hvis kontaktinnretningene ble montert på en bærestrimmel slik at ledninger fra forskjellige ledningspar kan innsettes i rekkefølge i slissene. Som følge av slissenes orientering i denne kjente ut-førelse, må ledningene legges i en ledningsholdejigg forut for tilkoblingen, slik at partier som skal opptas i slissene, strekker seg aksielt i forhold til kontaktinnretningen. Dette leggetrinn krever betydelig mer tid enn ganske enkelt å rette ledningene vinkelrett i forhold til strimmelen og nær hver ende av kontaktinnretningen, hvilket er av meget stor viktighet når det skal ut-føres et stort antall tilkoblinger. In a contact device known from US patent 3,406,247, the walls or edges of the wire slots lie in a plane perpendicular to the feeding direction of the contact devices if the contact devices were mounted on a carrier strip so that wires from different wire pairs can be inserted in sequence into the slots. As a result of the orientation of the slots in this known design, the cables must be laid in a cable holding jig prior to the connection, so that parts to be accommodated in the slots extend axially in relation to the contact device. This laying step requires considerably more time than simply straightening the wires perpendicular to the strip and near each end of the contact device, which is of very great importance when a large number of connections are to be made.

På bakgrunn av den ovenfor omtalte kjente teknikk be-står det nye og særegne ved den elektriske kontaktinnretning ifølge oppfinnelsen i første rekke i at første vegger for hvert hulrom ligger i et felles plan og at hver første vegg er utformet med to ledningsmottagende slisser i flukt med de respektive slisser i sin tilhørende klemme, og at klemmens langsgående vegger som danner On the basis of the above-mentioned known technology, the new and distinctive feature of the electrical contact device according to the invention is primarily that the first walls of each cavity lie in a common plane and that each first wall is designed with two wire-receiving slots flush with the respective slots in their associated clamp, and that the clamp's longitudinal walls which form

klemmens slisser ligger i et plan parallelt med den første vegg slik at ledninger anbragt i rett konfigurasjon slik at de strek- the clamp's slots lie in a plane parallel to the first wall so that wires placed in the right configuration so that they stretch

ning av kontaktinnretningen gjør det mulig å utføre et stort antall isolerte koblinger automatisk ved hjelp av forholdsvis ulært arbeidskraft samtidig som disse blir lite utsatt for tretthet, hvilket er meget fordelaktig når flere tusen enkeltforbindelser skal utføres under sammenskjøtning av to telefonkabler. Hånd-teringen av ledningen blir også lettere da de ledninger i hvert par som stikker ut fra en kabelende kan kobles samtidig til klemmene under anvendelse av det forannevnte apparat. ning of the contact device makes it possible to carry out a large number of isolated connections automatically with the help of relatively untrained labour, at the same time that these are little exposed to fatigue, which is very advantageous when several thousand individual connections are to be carried out while joining two telephone cables. The handling of the wire also becomes easier as the wires in each pair that protrude from one cable end can be connected simultaneously to the clamps using the aforementioned device.

Et annet eksempel på en slik kontaktinnretning som er Another example of such a contact device is

spesielt anvendbar ved fremstilling av forbindelser med uttak, er vist på figur 8. Dette utførelseseksempel har lignende konstruk-sjon som i den først beskrevne kontaktinnretning, men det er an-ordnet tre par ledningsmottagende slisser 35 for å oppnå uttaks-forbindelser som vist på figur 9. particularly applicable when making connections with outlets, is shown in Figure 8. This design example has a similar construction as in the first described contact device, but three pairs of wire-receiving slots 35 are arranged to achieve outlet connections as shown in Figure 9.
