Description
Tilkoblingsklemme til tilkobling av elektriske ledere uten avisolering i fordelere i fjernmeldingsanlegg, særlig telefonformidlingsanlegg Connection clamp for connecting electrical conductors without stripping in distributors in remote communication systems, especially telephone transmission systems
Oppfinnelsen angår en tilkoblingsklemme som tjener til tilkobling av elektriske ledere i fordelere i fjernmeldingsanlegg, særlig telefonformidlingsanlegg, uten avisolering, The invention relates to a connection clamp that serves to connect electrical conductors in distributors in remote communication systems, in particular telephone transmission systems, without stripping,
og består av to i lengderetningen adskilte fjærben som er stivt forbundet med hverandre ved sin ene ende og begrenser et langhull som forløper mellom klemområdet og den stive forbindelse mellom de to fjærben, samtidig som tilkoblingsklemmen er fremstilt av ett stykke av et metallisk båndmateriale og fjærbenene i klemområdet er adskilt ved klipping. and consists of two longitudinally separated spring legs which are rigidly connected to each other at one end and limit a long hole extending between the clamping area and the rigid connection between the two spring legs, while the connection clamp is made from one piece of a metallic strip material and the spring legs in the clamping area is separated by cutting.
En slik tilkoblingsklemme er kjent f.eks. fra DE-ASSuch a connection clamp is known, e.g. from DE-AS
12 32 232. På grunn av sin oppbygning er en slik tilkoblingsklemme enkel å fremstille. Imidlértid er det ugunstig at en tilkoblingsklemme med denne oppbygning ikke oppfyller de strenge krav til kontaktsikkerhet som ofte stilles i praksis. 12 32 232. Due to its structure, such a connection clamp is easy to produce. At the same time, it is disadvantageous that a connection terminal with this structure does not meet the strict requirements for contact safety that are often set in practice.
Den foreliggende oppfinnelse har til oppgave å forbedre en tilkoblingsklemme av den innledningsvis angitte art slik at de strenge krav til kontaktsikkerhet er oppfylt, samtidig som tilkoblingsklemmen er enkel å fremstille. The present invention has the task of improving a connection clamp of the type indicated at the outset so that the strict requirements for contact safety are met, while the connection clamp is easy to manufacture.
Denne oppgave blir løst ved at fjærbenene er slik forvridd i forhold til hverandre om en bøyekant som forløper loddrett på lengderetningen i tilkoblingens plan, at fjærbenene ved den ytre ende av klemområdet er forskutt et på forhånd gitt mål i forhold til hverandre. This task is solved by the spring legs being twisted in such a way in relation to each other about a bending edge that runs vertically in the longitudinal direction in the plane of the connection, that the spring legs at the outer end of the clamping area are offset by a predetermined measure in relation to each other.
Takket være forvridningen av de to fjærben oppfyller tilkoblingsklemmen ifølge oppfinnelsen, samtidig som den lar seg fremstille enkelt og billig, også strenge krav når det gjelder kontaktsikkerheten. Når en tråd føres inn, skjærer fjærbenene seg inn i tråden og blir dermed fiksert i stilling. De skår som oppstår ved innskjæringen, ligger på grunn av forvridnigen av de to fjærben forskutt en liten avstand i forhold til hverandre. Blir tråden nå skjøvet videre ned til sin definitive posisjon, vrir fjærbenene seg slik at der oppstår en ekstra torsjonskraft som bedrer kontaktegen-skapene hos tilkoblingsklemmen ifølge oppfinnelsen vesentlig. Thanks to the distortion of the two spring legs, the connection clamp according to the invention, while being simple and cheap to manufacture, also meets strict requirements in terms of contact safety. When a thread is fed in, the spring legs cut into the thread and are thus fixed in position. Due to the distortion of the two spring legs, the shards that occur during the incision are offset by a small distance in relation to each other. If the wire is now pushed further down to its definitive position, the spring legs twist so that an additional torsional force occurs which significantly improves the contact properties of the connection clamp according to the invention.
Ytterligere gunstige utforminger av tilkoblingsklemmen ifølge oppfinnelsen fremgår av underkravene og den følgende beskrivelse av utførelseseksempler. Further favorable designs of the connection clamp according to the invention appear from the sub-claims and the following description of design examples.
Utførelseseksempler såvel som virkemåten av tilkoblingsklemmen ifølge oppfinnelsen vil i det følgende bli beskrevet nærmere under henvisning til tegningen. Fig. 1 er et perspektivriss av en tilkoblings-enkeltklemme ifølge oppfinnelsen. Design examples as well as the operation of the connection clamp according to the invention will be described in more detail in the following with reference to the drawing. Fig. 1 is a perspective view of a connection single clamp according to the invention.
Fig. 2 er et sideriss av den samme.Fig. 2 is a side view of the same.
Fig. 3 er et perspektivriss av en tilkoblings-dobbeltklemme ifølge oppfinnelsen. Fig. 4-13 anskueliggjør i to projeksjoner enkelte til-stander av tilkoblings-enkeltklemmen under innklemningen av en isolert elektrisk leder. Fig. 3 is a perspective view of a connection double clamp according to the invention. Fig. 4-13 illustrates in two projections certain states of the connection single clamp during the clamping of an insulated electrical conductor.
Ved den tilkoblings-enkeltklemme 1 som er vist på fig.In the case of the single connection terminal 1 shown in fig.
I og 2, dreier det seg om en enkel stansedel av tynt båndmateriale med enkle ytterkonturer sammensatt av de rettlinjede ytterkanter av fjærbenene og klemmens innføringsgap 5. Det egentlige klemområde mellom klemkjevene 3 og 4 begrenses av klemmegapet 5 på den ene side og et langhull 2 på den annen. Dette klemområde skaffes med et enkelt skillesnitt. Gjennomrivningen av forbindelsen mellom de to klemkjever 3 og 4 skjer derunder i form av en forvridning som er be-stemmende for funksjonen av tilkoblingsklemmen ifølge oppfinnelsen. Takket være denne forvridning er de avisolerende kanter 6 og 7 av klemkjevene 3 og 4 fjernet fra hverandre en avstand a ved de ender som vender mot klemmegapet 5. I and 2, it is a simple punching part of thin strip material with simple outer contours composed of the rectilinear outer edges of the spring legs and the clamping insertion gap 5. The actual clamping area between the clamping jaws 3 and 4 is limited by the clamping gap 5 on one side and a long hole 2 on the other. This clamping area is obtained with a simple separation cut. The tearing through of the connection between the two clamping jaws 3 and 4 takes place underneath in the form of a distortion which is decisive for the function of the connection clamp according to the invention. Thanks to this distortion, the insulating edges 6 and 7 of the clamping jaws 3 and 4 are removed from each other by a distance a at the ends facing the clamping gap 5.
Fig. 3 viser en tilkoblings-dobbeltklemme ifølge den foreliggende oppfinnelse, bestemt for tilkobling av to iso-lerte elektriske ledere. Denne dobbelte tilkoblingsklemme 8 blir i prinsippet fremstilt på samme måte som beskrevet for enkeltklemmen på fig. 1 og 2, når unntas at der her behøves to skillesnitt pr. klemme. Mellom de to klemkjever 10 og II rager der inn en tunge 9 som ved sin rotende er stivt forbundet med rotendene av de to klemkjever 10 og 11. Den dobbelte tilkoblingsklemme har to langhull 12 og 13 samt to innførings-klemmegap 14 og 15, henholdsvis innenfor og utenfor de respektive klemområder. De to avisoleringskanter i et klemområde dannes av en og en kant av klemkjevene 10 Fig. 3 shows a connection double clamp according to the present invention, intended for connecting two insulated electrical conductors. This double connection terminal 8 is in principle produced in the same way as described for the single terminal in fig. 1 and 2, except that here two dividing sections are required per clamp. Between the two clamping jaws 10 and II, a tongue 9 protrudes, which at its root end is rigidly connected to the root ends of the two clamping jaws 10 and 11. The double connection clamp has two long holes 12 and 13 as well as two insertion clamp gaps 14 and 15, respectively within and outside the respective clamping areas. The two stripping edges in a clamping area are formed by one edge of the clamping jaws 10
og 11 samt en og en kant av tungen 9. Også ved denne utførel-sesform for tilkoblingsklemmen ifølge oppfinnelsen er de avisolerende kanter i de to klemområder fjernet fra hverandre en avstand a ved den ende som vender mot det respektive klemme-gap. and 11 as well as one edge of the tongue 9. Also in this embodiment of the connection clamp according to the invention, the insulating edges in the two clamp areas are removed from each other by a distance a at the end facing the respective clamp gap.
Virkemåten av tilkoblingsklemmen ifølge oppfinnelsenThe operation of the connection clamp according to the invention
vil der nå bli gjort rede for under henvisning til fig. 4-will now be explained with reference to fig. 4-
13. Fig. 4, 6, 8 og 10 er frontoppriss av koblingsklemmen 1, mens fig. 5, 7, 9 og 11 viser tverrsnitt gjennom tilkoblingsklemmen 1 resp. 11 i høyde med den elektriske leder, 13. Figs. 4, 6, 8 and 10 are front views of the connection clamp 1, while fig. 5, 7, 9 and 11 show cross-sections through the connection clamp 1 or 11 at the height of the electrical conductor,
og fig. 12 er et sideriss av klemmen etter innføring av lederen. and fig. 12 is a side view of the clamp after insertion of the conductor.
Takket være den valgte avskråning av innløpsgapet 5Thanks to the selected slope of the inlet gap 5
til tilkoblingsklemmen 1 trykker den innførte elektriske leder 14 tilkoblingsklemmene 1 noe fra hverandre før den med sin isolasjon 15 når de avisolerende kanter 6 og 7 (jfr. fig. 4). Når lederen 14 så trykkes inn mellom de avisolerende kanter 6 og 7 (jfr. fig. 6-9), skjærer disse kanter seg inn i tråden 16 og fikserer de to klemkjever 3 og 4 i sprikende stilling. Da klemkjevene 3 og 4 ved stanseoperasjonen - som tidligere anført - er blitt forvridd i forhold til hverandre, ligger de skår som de avisolerende kanter 6 og 7 forårsaker i tråden 16, forskutt i forhold til hverandre en avstand a. to the connection terminal 1, the introduced electrical conductor 14 presses the connection terminals 1 apart somewhat before it reaches the insulating edges 6 and 7 with its insulation 15 (cf. Fig. 4). When the conductor 14 is then pressed between the insulating edges 6 and 7 (cf. fig. 6-9), these edges cut into the wire 16 and fix the two clamping jaws 3 and 4 in a gaping position. As the clamping jaws 3 and 4 during the punching operation - as previously stated - have been distorted in relation to each other, the cuts which the stripping edges 6 and 7 cause in the wire 16 are offset in relation to each other by a distance a.
Blir den elektriske leder 14 nå trykket langs de avisolerende kanter 6 og 7, som er fiksert i tråden 16 ved skårene i denne, til sin definitive posisjon i klemområdet, dvs. like foran langhullet 2 (jfr. fig. 10-12), øker kontakt-trykket av de to klemkjever 3 og 4 mot tråden 16, da avstanden mellom den elektriske leder 14 og den lukkede ende av langhullet er minket. If the electrical conductor 14 is now pressed along the insulating edges 6 and 7, which are fixed in the wire 16 at the slits in it, to its definitive position in the clamping area, i.e. just in front of the long hole 2 (cf. fig. 10-12), increases the contact pressure of the two clamping jaws 3 and 4 against the wire 16, as the distance between the electrical conductor 14 and the closed end of the long hole is reduced.
Ved innføringen av den elektriske leder 14 i tilkoblingsklemmen 1 blir de avisolerende kanter 6 og 7 på grunn av den stive forbindelse mellom de to klemkjever 3 og 4 nedenfor langhullet 2 bøyet ut sidelengs. På grunn av den forhånds-bestemte forvridning mellom de avisolerende kanter 6 og 7 referert til planet for tilkoblingsklemmen 1, blir samtidig en av de avisolerende kanter 6 og 7 bøyet ut forover, mens den annen av disse kanter bøyes ut bakover. Derved fremkommer der en kileformet spalte som forløper i en bestemt vinkel til planet for tilkoblingsklemmen 1 og begrenses av kantene 6 og 7, og som tiltar i bredde mot klemmegapet 5. Denne spalte bevirker en vridning av de to klemkjever 3 og 4 så der blir utøvet en torsjonskraft p på disse i tillegg. Ved skårene i tråden 16 blir der derved gravet opp ekstra gråter som danner en tilleggskontaktflate utad. When the electrical conductor 14 is inserted into the connection clamp 1, the insulating edges 6 and 7 are bent sideways due to the rigid connection between the two clamping jaws 3 and 4 below the long hole 2. Due to the predetermined distortion between the insulating edges 6 and 7 referred to the plane of the connection terminal 1, at the same time one of the insulating edges 6 and 7 is bent forward, while the other of these edges is bent backward. Thereby, a wedge-shaped gap appears which runs at a certain angle to the plane of the connection clamp 1 and is limited by the edges 6 and 7, and which increases in width towards the clamp gap 5. This gap causes a twisting of the two clamping jaws 3 and 4 so that there is exerted a torsional force p on these in addition. At the shards in the wire 16, extra grooves are thereby dug up which form an additional contact surface on the outside.
Takket være sprikningen av fjærbenene kan kontaktflatene, som dannes ved hjelp av et skillesnitt, forsynes galvanisk med kontaktmaterialer, f.eks. Ag eller Sn. Tilkoblings-enkelt-klemmene resp. -dobbeltklemmene ifølge oppfinnelsen tjener - forlenget ved sin basis - som skille- eller koblingsfjærer i fordelerkomponenter. Thanks to the cracking of the spring legs, the contact surfaces, which are formed by means of a separation section, can be galvanically supplied with contact materials, e.g. Ag or Sn. The single connection terminals resp. - the double clamps according to the invention serve - extended at their base - as separating or connecting springs in distributor components.
