Opfindelsen angår et elektrisk forbindelsesorgan af den i krav l’s indledning angivne art.This invention relates to an electrical connector of the kind set forth in claim 1.
Der er tit brug for at kunne splejse sammenhørende ledninger fra bundter af ledningspar, f.eks. ved telefonkabler, og i betragtning af det store antal individuelle forbindelser (ofte flere tusinde) , som skal foretages, er det vigtigt, at hver forbindelse kan udføres så hurtigt som muligt under anvendelse af halvautomatisk værktøj eller ved anvendelse af halvautomatiske apparater.It is often necessary to be able to splice related wires from bundles of wiring pairs, e.g. by telephone cables, and given the large number of individual connections (often thousands) to be made, it is important that each connection can be made as quickly as possible using semi-automatic tools or using semi-automatic devices.
Det er også vigtigt, at forbindelserne optager ringe plads, da der som regel ikke er megen plads i kabelskakter eller lignende.It is also important that the connections take up little space, as there is usually not much room in cable shafts or the like.
Formålet med opfindelsen er at angive et elektrisk forbindelsesorgan, som opfylder de ovenstående krav, og som kan anvendes i forbindelse med et halvautomatisk apparat ved indføring af ledninger, f.eks. det apparat, der er angivet i beskrivelsen til USA-patent 3 975 812. I dette apparat bliver forbindelsesorganerne påmonteret en fleksibel bærestrimmel og knyttet til ledningsindføringsstationer på hver side af strimmelen, hvor indføringsstemplet skyder ledningerne ind i klemmeslidser i forbindelsesorganet. For at kunne foretage de mange tusinde tilkoblinger, som skal udføres (f.eks. mellem telefonkabler) så hurtigt som muligt, er det vigtigt at ledningerne kræver så lille håndtering som muligt af installatøren forud for tilkoblingen ved hjælp af nævnte apparat. Dette bliver opnået ved anvendelse af forbindelsesorganet ifølge opfindelsen. Som det vil fremgå anbringes klemmerne ryg mod ryg med de langsgående vægge eller kanter, som danner klemmernes slidser, liggende i et plan, som indeholder bærestrimmelens fremføringsretning, medens de nævnte kanter strækker sig vinkelret på denne retning.The object of the invention is to provide an electrical connector which meets the above requirements and which can be used in conjunction with a semi-automatic apparatus for inserting wires, e.g. in the apparatus disclosed in U.S. Patent No. 3,975,812. In this apparatus, the connecting means are mounted on a flexible support strip and attached to wire insertion stations on each side of the strip, the insertion piston pushing the wires into terminal slots in the connecting means. In order to be able to make the many thousands of connections that need to be made (eg between telephone cables) as quickly as possible, it is important that the wires require as little handling as possible by the installer prior to the connection using said device. This is achieved by using the connector according to the invention. As will be seen, the clamps are positioned back to back with the longitudinal walls or edges forming the slits of the clamps lying in a plane containing the direction of travel of the carrier strip, while said edges extend perpendicularly to this direction.
I tilknytning til ovenstående skal det imidlertid bemærkes, at det heri angivne forbindelsesorgan også er anvendeligt i andre forbindelser end ved strimmelforbindelse som beskrevet.However, in connection with the foregoing, it should be noted that the connecting means set forth herein is also useful in compounds other than by strip compound as described.
Det er en ulempe ved de kendte forbindelsesorganer, at der optræ- 2It is a disadvantage of the known connecting means that 2 occurs
DK 15166 2 BDK 15166 2 B
der vanskeligheder ved manipulering og placering af begge tilsvarende ledninger i de ledningspar, som skal tilkobles, da der under tilkoblingsoperationen foreligger risiko for, at de første ledninger forskydes fra slidserne, før de andre ledninger tilkobles, eller at det er nødvendigt at anvende kamlignende skabeloner til at fastholde begge ledningspar således, at de kan tilkobles samtidig.there are difficulties in manipulating and placing both corresponding wires in the wiring pairs to be connected, since during the wiring operation, there is a risk that the first wires will be offset from the slots before the second wires are connected or that comb-like templates are needed for to hold both pairs of wires so that they can be connected simultaneously.
Fra USA-patentskrift nr. 3 406 247 kendes et forbindelsesorgan, hvor væggene eller kanterne af ledningsslidserne ligger i et plan vinkelret på forbindelsesorganernes indføringsretning, hvis forbindelsesorganerne blev monteret på en bærestrimmel, således at ledningerne fra forskellige ledningspar kan indsættes i rækkefølge i slidserne. Som følge af slidsernes orientering i denne kendte udførelsesform må ledningerne lægges i en skabelon til at holde ledningerne forud for tilkoblingen, således at dele, som skal optages i slidserne, strækker sig aksialt i forhold til forbindelsesorganet. Dette trin med ledningslægningen kræver betydelig mere tid, end hvis man ganske enkelt retter ledningerne vinkelret på strimmelen og nær hver ende af forbindelsesorganet, hvilket er af stor vigtighed, når der skal udføres et stort antal tilkoblinger.U.S. Patent No. 3,406,247 discloses a connector where the walls or edges of the conductor slots lie in a plane perpendicular to the direction of insertion of the connectors if the connectors are mounted on a support strip so that the wires of various wires may be inserted sequentially into the slots. Due to the orientation of the slits in this known embodiment, the wires must be placed in a template for holding the wires prior to the connection so that parts to be accommodated in the slots extend axially with respect to the connecting means. This step of wiring requires significantly more time than simply aligning the wires perpendicular to the strip and near each end of the connector, which is of great importance when a large number of connections are to be made.
På baggrund af den ovenstående kendte teknik er det indledningsvis angivne elektriske forbindelsesorgan ifølge opfindelsen ejendommeligt ved det i krav l's kendetegnende del angivne.In view of the above known technique, the electrical connection means according to the invention initially indicated is characterized by the characterizing part of claim 1.
Med denne løsning kan sammenhørende ledninger indsættes samtidigt i modsatte ender af forbindelsesorganet og holdes på sikker måde i slidserne under indsættelsen af de andre sammenhørende ledninger i ledningsparrene. En anden fordel består i, at det her angivne forbindelsesorgan desuden er meget kompakt og gør det muligt at fremstille det isolerende hus under et enkelt sprøjtestøbningstrin.With this solution, associated wires can be inserted simultaneously at opposite ends of the connector and securely held in the slots during insertion of the other connected wires into the wiring pairs. Another advantage is that the connecting member disclosed herein is additionally very compact and allows the insulating housing to be manufactured during a single injection molding step.

Forbindelsesorganet 10 omfatter et isolerende hus 11, som er støbt i et stykke af et passende formstof og omfatter to metalforbindelse selementer 12, som er anbragt i hulrum 13 i modstående ender af huset.11.The connecting member 10 comprises an insulating housing 11 which is molded in a piece of a suitable plastic material and comprises two metal connection elements 12 which are arranged in cavities 13 at opposite ends of the housing.11.
Hvert forbindelseselement er U-formet, og i de modstående sidevægge findes der med indbyrdes afstand flugtende, ledningsoptagende slidser 14 og 15 samt et mellemliggende par af slidser 17, som tillader indbyrdes uafhængig udbøøning af de med slidser forsynede sidevægge. Slidserne er arrangeret parvist overfor hinanden, og den ene slids i et par, d.v.s. i den ene sidevæg, har en fra den anden slids i parret forskellig bredde, således at hvert par slidser omfatter en kontaktdannende og en ledningsaflastende slids.Each connecting element is U-shaped, and in the opposite side walls there are spaced-apart, conductive slots 14 and 15 as well as an intermediate pair of slots 17 which allow for independently deflection of the slotted side walls. The slots are arranged in pairs opposite each other, and one slot in a pair, i.e. in one side wall, one width is different from the other slot in the pair so that each pair of slots includes a contact forming and a wire relieving slot.
Hvert af husets hulrum 13 har en overside og underside 19 og 20, som ligeledes er forsynet med slidser 21 henholdsvis 22, som flugEach of the housing cavities 13 has an upper and lower sides 19 and 20, which are also provided with slots 21 and 22, respectively, for flight.

4 ter med de ledningsoptagende slidser 14 og 15· Oversiderne er smk= ket ved 23.til frembringelse af eftergivelige fingre 24, som stræk-ker sig skråt hen over slidserne 14 og 15 og slutter et sted mellem disse slidsers ender. Bunden 25 af slidserne 21 er udvidet til frembringelse af et eftergiveligt mellemstykke 26. Slidserne 21 divergerer imod deres åbne ender, hvor de er aftrappede ved 27.The upper sides are narrowed by 23. to produce resilient fingers 24 which extend obliquely across the slots 14 and 15 and terminate somewhere between the ends of these slots. The bottom 25 of the slots 21 is expanded to provide a resilient intermediate piece 26. The slots 21 diverge toward their open ends where they are stepped at 27.
Husets bundplade 29 har reduceret bredde, således at der skabes adgang for et ledningsindsættende værktøj ved begge ender af huset.The housing base plate 29 has reduced width so as to provide access for a cord inserting tool at both ends of the housing.
Huset kan fremstilles på strimmelform ved at føre en perforeret bærestrimmel 31 af et passende formstof eller metal gennem en støbemaskines støbeform, hvor husene støbes på strimlen. Støbeformene har udskæringer, således at lidt af støbemassen kan flyde gennem strimlens perforering til dannelse af fremspring 32 på bærestrimlens underside. Fremspringene vil kunne holde husene fast på strimlen, men husene kan let frigives fra strimlen ved at anvende det i beskrivelsen til U.S.A. patent nr. 3 975 812 angivne apparat, som også kan anvendes til at opsplitte sammenhørende ledninger i ledningspar.The housing can be made in strip form by passing a perforated carrier strip 31 of a suitable resin or metal through the mold of a molding machine, the housings being molded onto the strip. The molds have cutouts so that some of the molding mass can flow through the perforation of the strip to form projections 32 on the underside of the carrier strip. The protrusions will be able to hold the housings to the strip, but the housings can be easily released from the strip by using it in the U.S.A. No. 3,975,812, which can also be used to split connected wires into pairs of wires.
Når hver ledning tvinges ind i husets slidser 21, vil mellemstykket 26 og fingeren 24 blive bøjet tilside således, at ledningen kan indføres i forbindelseselementets slidser 15 eller 16 (se fig. 6).As each wire is forced into the slots 21 of the housing, the intermediate piece 26 and the finger 24 will be bent aside so that the cord can be inserted into the slots 15 or 16 of the connecting member (see Fig. 6).
Ved indsættelse af ledningen vil slidsernes vægge i nærheden af fingrene 24 gennemtrænge ledningens isolation til tilvejebringelse af elektrisk forbindelse, medens den anden slids i forbindelseselementet fortrinsvist kun trænger delvist gennem isoleringen og således tjener som ledningsaflastning. Når ledningen er helt på plads i slidsen, vil den elastiske finger 24 bøje tilbage, således at dennes frie ende ligger hen over ledningen og holder denne fast i slidsen (fig. 7). Strimlen 31 kan derefter blive ført frem for montering af det næste ledningspar.Upon insertion of the wire, the walls of the slots in the vicinity of the fingers 24 will penetrate the insulation of the wire to provide electrical connection, while the other slot in the connecting element preferably penetrates only partially through the insulation and thus serves as wire relief. When the cord is fully in place in the slot, the elastic finger 24 will bend back so that its free end lies over the cord and holds it in the slot (Fig. 7). The strip 31 can then be advanced to mount the next pair of wires.
Forbindelsesorganerne kan fremstilles i meget små dimensioner (f.eks. 12 x 8 x 8 mm). De elastiske fingre tjener ikke alene tilThe connecting means can be made in very small dimensions (eg 12 x 8 x 8 mm). The elastic fingers do not only serve
