149291149291
Opfindelsen vedrører en fremgangsmåde til frembringelse af elektrisk forbindelse mellem en elektrisk ledning og et elektrisk forbindelse sorgan som angivet i krav l’s indledning.The invention relates to a method of making an electrical connection between an electrical wire and an electrical connection means as set forth in claim 1.
I beskrivelsen til USA patent nr. 3.410.950 er beskrevet en fremgangsmåde til frembringelse af elektrisk forbindelse mellem en elektrisk ledning og et elektrisk forbindelsesorgan med en sammen-klemmelig metalferrule, ved hvilken fremgangsmåde der tilføres fer-rulen et tryk således, at en til en aflang grundplade fastgjort del af ferrulen bringes til at tvinge ledningen i en spalte i en fra grundpladen opretstående tunge, hvorved ledningen forbindes elektrisk til ferrulen tinder gennemskæring af isolationen.U.S. Patent No. 3,410,950 discloses a method of making electrical connection between an electrical conduit and an electrical connector with a clampable metal ferrule, the method of which is applied to a ferrule such that one to one oblong base plate fixed part of the ferrule is caused to force the wire in a slot in a tongue raised from the base plate, whereby the wire is electrically connected to the ferrule, cutting through the insulation.
2 1492912 149291
Ved fremgangsmåden ifølge det ovennævnte USA patent tvinges ledningen ned i spalten ved hjælp af en flig, som udgår fra en sidevæg i ferrulen, og som ved sammenklemning af ferrulen tvinges nedad mod grundfladen af en del af ferrulens sidevæg, fra hvilken fligen er udstanset. Denne metode har den ulempe, at der er påkrævet en relativ høj sammenklemningskraft til tilvejebringelse af den elektriske forbindelse, og at der skal anvendes en relativ stor mængde metal til fremstilling af den sammenklemmelige ferrule. Den relativt høje sammenklemningskraft skyldes, at den kendte ferrule rules stivhed forudsætter, at fligene er fastgjort til en grundplade ved hjælp af relativt stive sidevægge, som skal deformeres ved sammenklemning af forbindelsesorganet.In the method of the above-mentioned United States patent, the cord is forced into the slot by means of a tab starting from a side wall of the ferrule and which, by squeezing the ferrule, is forced downwardly towards the base surface of a portion of the side wall of the ferrule from which the tab is punched. This method has the disadvantage that a relatively high clamping force is required to provide the electrical connection and that a relatively large amount of metal must be used to produce the clampable ferrule. The relatively high clamping force is due to the rigidity of the known ferrule rule assuming that the tabs are attached to a base plate by means of relatively rigid sidewalls which are to be deformed by clamping of the connecting member.
Formålet med opfindelsen er at undgå de nævnte ulemper, hvilket opnås ved at udøve fremgangsmåden som angivet i krav l’s kendetegnende del.The object of the invention is to avoid said disadvantages, which is achieved by practicing the method as set out in claim 1.
Til ombukning af de nævnte fingre skal der til sammenligning med den kendte teknik kun anvendes en relativ lille sammenklemningskraft, som f.eks. kan tilvejebringes ved hjælp af et håndværktøj eller et værktøj, som drives af en lille motor, og endvidere opnås at der forbruges en mindre mængde metal til fremstilling af sammenklemningsferrulen end den mængde, der skal anvendes til fremstilling af ferrulen ifølge det ovennævnte USA-patentskrift. Yed at der ifølge opfindelsen findes et par fingre på hver sin side af tungen og i umiddelbar nærhed af denne sikres det, at ledningen drives helt ned i spalten og fastholdes på pålidelig måde.For the folding of said fingers, only a relatively small clamping force is used, for example with the prior art, e.g. may be provided by a hand tool or a tool driven by a small motor, and furthermore, a lesser amount of metal is consumed to produce the squeeze ferrule than the amount to be used to produce the ferrule of the above-mentioned United States patent. In accordance with the invention, a pair of fingers are provided on either side of the tongue and in the immediate vicinity of the tongue it is ensured that the cord is driven fully into the slot and reliably retained.
Fortrinsvis udøves fremgangsmåden som anført i krav 2, hvorved det opnås at en eventuel elastisk tilbagebøjning af de deformerede fingre klemmer ledningen fastere i slidsen i modsætning til den kendte teknik, hvor en elastisk tilbagebøjning medfører, at trykket mod ledningen svækkes.Preferably, the method as claimed in claim 2 is performed, whereby any elastic bending of the deformed fingers is clamped to the conduit more firmly in the slit, as opposed to the prior art, where an elastic bending causes the pressure against the conduit to weaken.
Opfindelsen vedrører endvidere et elektrisk forbindelsesorgan til udøvelse af fremgangsmåden.The invention further relates to an electrical connector for carrying out the method.
Forbindelsesorganet er ejendommeligt ved den i krav 3*s kendetegnende del angivne udformning.The connecting means is peculiar to the design specified in claim 3 *.

Fingrenes skrå, frie endedele tjener som ovenfor nævnt til at lede ledningen ind i spalten og til at fastholde ledningen ved spaltens bund efter sammenklemningsoperationen.As mentioned above, the inclined, free end portions of the fingers serve to guide the wire into the slot and to hold the wire at the bottom of the slot after the squeezing operation.
Som anført i krav 4 kan et andet par af modsatte, opretstående fingre være anbragt i en ende af ferrulen, hvilke fingre er kortere end de førstnævnte fingre, og hvor de andre fingres skrånende del er længere end de førstnævnte fingres skrånende del, hvilke dele ved kontakt med modstående sider af ledningen tjener til at centrere ledningen under sammenklemningsoperationen.As set forth in claim 4, another pair of opposite upright fingers may be disposed at one end of the ferroller, which fingers are shorter than the first fingers and the sloping portion of the other fingers is longer than the sloping portion of the former fingers, which portions at contact with opposite sides of the cord serves to center the cord during the squeezing operation.
Opfindelsen vil blive nærmere forklaret ved den følgende beskrivelse af nogle udførelsesformer, under henvisning til tegningen, hvor fig. 1 i perspektiv viser en strimmel af elektriske forbindelsesorganer, fig. 2 perspektivisk og forstørret et forbindelsesorgan fra den i fig. 1 viste strimmel, fig. 3 perspektivisk forbindelsesorganet sammenklemt omkring to ledninger, fig. 4 fra enden forbindelsesorganet anbragt på en sammenklemningsambolt, hvor den med ambolten samvirkende sammenklemningsbakke er vist, fig. 5-8 det samme som fig, 4, hvor fremskredne stadier af sammenklemningsoperationen kan ses, fig. 9 et tværsnit langs linien IX-IX i fig. 3, fig. 10 et tværsnit langs linien X-X i fig. 3, fig. 11 et forstørret billede af det i fig. 2 viste forbindelsesorgan set fra oven, medens fig. 12-15 viser forskellige modifikationer af forbindelsesorganet.The invention will be explained in more detail in the following description of some embodiments, with reference to the drawing, in which fig. 1 is a perspective view of a strip of electrical connectors; FIG. 2 is a perspective view and enlarged of a connector of the embodiment shown in FIG. 1; FIG. 3 is a perspective view of the connecting means clamped around two wires; FIG. 4 from the end of the connecting means arranged on a clamping embosser, where the clamping tray cooperating with the anvil is shown; FIG. 5-8 the same as Fig. 4, where advanced stages of the squeezing operation can be seen; 9 is a cross section along line IX-IX of FIG. 3, FIG. 10 is a cross-sectional view taken along the line X-X of FIG. 3, FIG. 11 is an enlarged view of the embodiment of FIG. 2 as seen from above, while FIG. 12-15 show various modifications of the connector.
Under henvisning til fig. 2, 4 og 11 ses forbindelsesorganet 2 omfattende en i det væsentlige U-formet sammenklemmelig metalferrule , 149291 4 4 med en aflang grundplade 12, fra hvis modsatte langsgående kanter sidevæggene 14 og 14a strækker sig, hvilke sidevægge er udformet sammenhængende med grundpladen 12. Sidevæggene 14 og 14a divergerer en smule i retning væk fra grundpladen 12. Sammenhængende med sidevæggene 14 og 14a strækker sig fra væggenes frie langsgående kanter nogle par af fingre 26, 26a, 28, 28a, 30, 30a, 32, 32a. Til ferru-lens 4’s ydre overflade er fastgjort en film 6 af et isolerende materiale, f.eks. polyethylenterephthalat, hvor dele 5 af filmen 6 strækker sig i længderetningen ud over ferrulen 4’s ender, og dele 7 af filmen 6 strækker sig forbi fingrene i retning væk fra grundpladen 12. Filmen 6 har i de langsgående kanter to centralt beliggende udskæringer 48. På begge sider af udskæringerne 48 har ferrulen 4 to opretstående tunger 16 og 18 med en centralt beliggende spalte 20, som åbner sig mod den af tungens kanter, som vender bort fra grund-pladen 12, hvor den til tungen 16 hørende spalte 23 er en smule bredere end spalten 20. Bunden af hver spalte 20, som åbner sig mod den af tungens kanter, som vender bort fra grundpladen 12, hvor den til tungen 16 hørende spalte 23 er en smule bredere end spalten 20. Bunden af hver spalte 20 og 23 er beliggende mellem grundpladen 12 og sidevæggene 14 og l4a's langsgående kanter. Begge spalter 20 og 23 har en ledningsmodtagende åbning 24. Fingrene 26, 26a, 28, 28a, 30 og 30a er identiske. Som vist i fig. 4 har hver af disse fingre en del 34, som strækker sig fra sidevæggen 14 eller 14a, og som er parallel med sidevæggen, og har en endedel 36, som ved hjælp af en bøjning 38 er forbundet til delen 34, hvilken del 36 strækker sig ind i ferrulen 4 og skråner mod grundpladen 12 fra bøjningen 38.Referring to FIG. 2, 4 and 11, the connecting member 2 comprising a substantially U-shaped clampable metal ferrule is seen with an elongate base plate 12, from which the opposite longitudinal edges extend sidewalls 14 and 14a, which side walls are formed in conjunction with the base plate 12. The side walls 14 and 14a diverge slightly in direction away from the base plate 12. In conjunction with the side walls 14 and 14a, some pairs of fingers 26, 26a, 28, 28a, 30, 30a, 32, 32a extend from the free longitudinal edges of the walls. To the outer surface of the ferrule 4 is attached a film 6 of an insulating material, e.g. polyethylene terephthalate, wherein portions 5 of the film 6 extend longitudinally beyond the ends of the ferrule 4, and portions 7 of the film 6 extend past the fingers away from the base plate 12. The film 6 has at its longitudinal edges two centrally located cuts 48. On both sides of the cutouts 48, the ferrule 4 has two upright tongues 16 and 18 with a centrally located slot 20 which opens against that of the tongue edges facing away from the base plate 12, where the slot 23 of the tongue 16 is slightly wider than the slot 20. The bottom of each slot 20 which opens against that of the tongue edges facing away from the base plate 12, where the slot 23 of the tongue 16 is slightly wider than the slot 20. The bottom of each slot 20 and 23 is located between the base plate 12 and the longitudinal edges 14 and 14a of the side walls. Both slots 20 and 23 have a conduit receiving opening 24. The fingers 26, 26a, 28, 28a, 30 and 30a are identical. As shown in FIG. 4, each of these fingers has a portion 34 extending from the sidewall 14 or 14a, parallel to the sidewall, and having an end portion 36 which is connected by a bend 38 to the portion 34, which portion 36 extends into the ferroller 4 and slopes toward the base plate 12 from the bend 38.
Som det kan ses i fig. 11 er hvert par fingre 28 og 28a anbragt mellem tungerne 16 og 18, hvor fingrenes bredde er mindre end afstanden mellem tungerne, og hvor fingrene er tæt beliggende op til tungerne, regnet i grundpladen 12’s længderetning. Regnet i samme retning er hvert par af fingre 26 og 26a anbragt tæt ved tungerne 18 og mellem tungerne og udskæringerne 48. I en vis afstand fra tungerne. 16 er hvert par af fingre 30 og 30a anbragt tæt ved tungerne 16 på den modsatte side af disse i forhold til udskæringerne 48. Hvert par af fingre 32 og 32a er anbragt ved ferrulen 4*s ender, hvilke fingre er en smule kortere end de tidligere nævnte fingre. Fingrene 32 og 32a1 s endedele 42 og 42a er længere end de andre 5 149291 fingres endedele 36 og strækker sig således længere ind i ferrulen 4.As can be seen in FIG. 11, each pair of fingers 28 and 28a is disposed between tongues 16 and 18, where the width of the fingers is less than the distance between the tongues and where the fingers are close to the tongues, calculated in the longitudinal direction of the base plate 12. Calculated in the same direction, each pair of fingers 26 and 26a is positioned close to the tongues 18 and between the tongues and the cutouts 48. At some distance from the tongues. 16, each pair of fingers 30 and 30a is positioned close to the tongues 16 on the opposite side thereof relative to the cutouts 48. Each pair of fingers 32 and 32a is disposed at the ends of the ferrule 4 *, which fingers are slightly shorter than the previously mentioned fingers. The end portions 42 and 42a of the fingers 32 and 32a1 are longer than the end portions 36 of the other fingers and thus extend further into the ferrule 4.
Som vist i fig. 3 er forbindelsesorganet 2 indrettet til at blive sammenklemt omkring enderne af to ledninger 8 og 10, med en ledning beliggende på hver sin side af udskæringerne 48. i det følgende vil der kun blive beskrevet sammenklemningen omkring ledningen 8.As shown in FIG. 3, the connecting member 2 is arranged to be clamped around the ends of two wires 8 and 10, with a conduit located on either side of the cuts 48. In the following, only the clamping around the conduit 8 will be described.
Fig. 4 viser forbindelsesorganet 2 anbragt på arbejdsfladen 58 af en sammenklemningsambolt 56, hvor forbindelseselementets grundplade hviler mod fladen 58. En til samvirken med ambolten 56 modsvarende sammenklemningsbakke 54 har et hulrum 57 med en indre overflade 60, som konvergerer stærkt i opadgående retning, og som går over i en indre overflade 62, der konvergerer mindre og samler sig i en spids 66 via de bueformede overflader 64.FIG. 4 shows the connecting member 2 arranged on the working surface 58 of a clamping anvil 56, the base plate of the connecting member resting against the surface 58. A clamping tray 54 corresponding to the anvil 56 has a cavity 57 with an inner surface 60 which converges strongly in an upward direction and which extends into an inner surface 62 which converges less and accumulates in a tip 66 via the arcuate surfaces 64.
Ledningen 8, som skal fastklemmes i forbindelsesorganet 2, er vist i en stilling lige under spidsen 66 (se fig. 4). Ledningen 8 har en centralt beliggende elektrisk ledende kerne 70 omgivet af en isolering 68.The conduit 8 to be clamped in the connector 2 is shown in a position just below the tip 66 (see Fig. 4). The conduit 8 has a centrally located electrically conductive core 70 surrounded by an insulation 68.
Når bakken 54 bevæges mod ambolten 56, vil ledningen 8 uanset dens begyndelsesstilling (som ikke behøver at være som vist i fig. 4) blive styret af delene 36 til den i fig, 5 viste stilling. I denne stilling er delene 7 af den isolerende film 6 bøjet omkring som vist i fig. 5, som følge af de bueformede overflader 64, og alle fingrene samt sidevæggene 14 og 14a er blevet bøjet en smule indad, således at de i hovedsagen danner en ret vinkel med grundpladen 12.As the tray 54 moves toward the anvil 56, the line 8, regardless of its initial position (which need not be as shown in Figure 4), is guided by the parts 36 to the position shown in Figure 5. In this position, the portions 7 of the insulating film 6 are bent around as shown in FIG. 5, as a result of the arcuate surfaces 64, and all the fingers as well as the side walls 14 and 14a have been slightly bent inwardly so that they generally form a right angle with the base plate 12.
Når sammenklemningen fortsætter, vil endedelene 36 berøre ledningens 8's øvre overflade (fig. 6 og 7) på en sådan måde, at ledningen tvinges ned i spalterne 20 og 23, idet de styres af de ledningsmodtagende åbninger 24. I det i fig. 6 viste stadie af sammenklemningen strækker fingrene 32 og 32a’s dele 42 og 42a sig parallelt med hinanden vinkelret på grundpladen 12, hvor disse fingres modstående overflader 43 og 43a tjener til at centrere ledningen · nøjagtigt i forhold til spalterne 20 og 23. Som vist i fig. 7 bøjes alle fingrene yderligere om, hvilket imidlertid først forekommer efter, at ledningen er blevet klemt ned i spalterne.As the clamping continues, the end portions 36 will touch the upper surface of the conduit 8 (Figs. 6 and 7) in such a way that the conduit is forced down into the slots 20 and 23, guided by the conduit receiving openings 24. In the embodiment shown in Figs. 6, the parts 42 and 42a of the fingers 32 and 32a extend parallel to each other perpendicular to the base plate 12, where the opposing surfaces 43 and 43a of these fingers serve to center the conduit exactly with respect to the slots 20 and 23. As shown in FIG. . 7, all fingers are further bent, which, however, only occurs after the cord has been squeezed into the slots.
6 1492916 149291
Delene 7 af filmen 6 bøjes ligeledes omkring af overfladerne 64 og berører hinanden i forbindelsesorganets midte, som vist i fig. 6, hvorefter delene 7 fastlåses mellem fingrenes modstående bueformede overflader som vist i fig. 7.The portions 7 of the film 6 are also bent around by the surfaces 64 and touch each other in the center of the connector, as shown in FIG. 6, after which the parts 7 are locked between the opposite curved surfaces of the fingers as shown in FIG. 7th
Spalten 20’s bredde er mindre end ledningen 8*s kerne 70’s diameter således, at spalten 20’s kanter vil trænge igennem ledningen 68's isolation og klemme sammen omkring kernen 70, hvorved der opnås en god elektrisk forbindelse mellem kernen 70 og ferrulen 4, når ledningen klemmes ned i spalten* Når ledningen klemmes ned i spalten 23, som er lidt bredere end spalten 20, vil denne spaltes kanter trænge gennem isolationen 68 men vil imidlertid ikke klemme så hårdt sammen omkring kernen 70, som tilfældet var med spalten 20, hvorved kernen 70’s trækstyrke ikke forringes*The width of the gap 20 is smaller than the diameter of the conduit 8 * core 70 so that the edges of the gap 20 will penetrate the insulation of the conduit 68 and clamp around the core 70, thereby providing a good electrical connection between the core 70 and the ferroller 4 as the conduit is clamped down. in the slot * When the cord is clamped into the slot 23 which is slightly wider than the slot 20, the edges of this slot will penetrate through the insulation 68 but will not clamp as tightly around the core 70 as was the case with the slot 20, thereby providing the tensile strength of the core 70 do not deteriorate *
Som vist i fig. 11 er alle fingrene anbragt og dimensioneret således, at de ikke berører tungerne 16 og 18 under sammenklemningsoperationen. Af denne grund er hver af fingrene 28 og 28afs bredde mindre end afstanden mellem tungerne.As shown in FIG. 11, all fingers are arranged and dimensioned so that they do not touch tongues 16 and 18 during the squeezing operation. For this reason, each of the fingers 28 and 28afs width is less than the distance between the tongues.
Afhængig af ledningens dimension og spalten 20rs bredde vil tungen 18 i det væsentlige blive udbøjet til siden, d.v.s. spalten 20’s kanter fjerner sig en smule fra hinanden. I fig. 7 og 8 er tungen 20 vist deformeret, svarende til at ledningens diameter er relativ stor i forhold til spaltens bredde. Ϊ tilfælde af en mindre ledning vil en spredning af spalten 20·s kanter næppe kunne konstateres.Depending on the dimension of the conduit and the gap 20r the tongue 18 will be substantially bent to the side, i.e. the gap 20's edges are slightly apart. In FIG. 7 and 8, the tongue 20 is shown to be deformed, corresponding to the diameter of the conduit being relatively large relative to the width of the slot. Ϊ In case of a smaller conduit, a spread of the edges of the gap 20 · can hardly be detected.
Når sammenklemningen er tilendebragt, vil fingrene 28 og 28a*s modstående bueformede overflader udøve et pres på ledningens isolation 68 som vist i fig. 9. Fingrene 26, 26a, 30 og 30a vil på lignende måde udøve et tryk på ledningen 8. Fingrene 32 og 32a's bueformede dele berører ledningens overflade et stykke fra organet 4’s grundplade 12, og tilvejebringer derved en spændingsaflastning, samt fastholder ledningen centralt i forhold til forbindelsesorganet som vist i fig. 3.When the clamping is completed, the opposing curved surfaces of the fingers 28 and 28a * will exert pressure on the insulation 68 of the conduit as shown in FIG. 9. The fingers 26, 26a, 30 and 30a will similarly exert pressure on the conduit 8. The arcuate parts of the fingers 32 and 32a touch the surface of the conduit a distance from the base plate 12 of the member 4, thereby providing a relief of tension, and maintaining the conduit centrally in relation to the conduit. to the connector as shown in FIG. Third
Til anvendelse i forbindelse med et automatisk sammenklemningsapparat fremstilles forbindelsesorganerne i strimmelform som vist i fig. 1, hvor filmen 6 for hvert forbindelsesorgan er forbundet i 7 149291 begge ender til et bærebånd 50, således at forbindelsesorganerne ligger parallelt side om side og er indbyrdes forbundne via båndene 50. Til at begynde med bearbejdes en metalplade til frembringelse af en strimmel flade emner til dannelse af ferrulerne 4, hvor emnerne fastgøres til et sammenhængende strimmelfilmmateriale, som udgør forbinde 1se sorganernes film 6 samt bærebåndene 50. Derefter gennemskæres strimmelen imellem metalemnerne, som derefter gives den U-formede facon. Det færdige bånd af forbindelsesorganer er egnet til anvendelse i forbindelse med et sammenklemningsapparat, som f.eks. det i beskrivelsen til britisk patent nr. 1.176.104 angivne; Udskæringerne 48 tjener til at modtage en lederibbe i apparatets frem-f øringsmekani sme.For use in connection with an automatic squeezing apparatus, the connector means are made in strip form as shown in FIG. 1, wherein the film 6 for each connecting member is connected at both ends to a carrier belt 50 such that the connecting means are parallel to one another and are interconnected via the belts 50. First, a metal plate is processed to produce a strip of flat blanks. to form the ferrules 4, wherein the blanks are attached to a coherent strip film material which connects the film 6 of the organs as well as the straps 50. Then the strip is cut between the metal blanks which are then given the U-shaped shape. The finished band of connecting means is suitable for use in conjunction with a clamping apparatus such as e.g. the disclosure of British Patent No. 1,176,104; The cutouts 48 serve to receive a guide rib in the delivery mechanism of the apparatus.
Den sammenklemmelige ferrule kan fremstilles af et hvilket som helst passende metal, f.eks. 3/4 hård messing (70# kobber - 30# zink) eller en phosphorbronze. Forbindelsesorganet kan have en samlet længde på ca. 2,4 cm, en bredde på ca. 0,46 cm og en højde på ca.The squeeze ferrule can be made of any suitable metal, e.g. 3/4 hard brass (70 # copper - 30 # zinc) or a phosphor bronze. The connector may have a total length of approx. 2.4 cm, a width of approx. 0.46 cm and a height of approx.
0,33 cm. Hvis ferrulerne 4 fremstilles af messing, vil metalpladen have en tykkelse på ca. 0,4 mm, hvilket giver forbindelsesorganer, som svarer til ledningerne A.W.G. 26 til 17.0.33 cm. If the ferrules 4 are made of brass, the sheet metal will have a thickness of approx. 0.4 mm, providing connecting means corresponding to the wires A.W.G. 26 to 17.
En fordel ved det ovenfor beskrevne forbindelsesorgan er, at ledningen ledes nøjagtigt ind i spalterne 20 og 23, og de ombøjede fingre sikrer, at ledningen trykkes mod spalternes bund, hvorved der sikres en god forbindelse mellem ledningen 8’s kerne 70 og den sammenklemmelige metalferrule 4. Måden hvorpå ledningen centreres i forhold til forbindelsesorganet er vist i fig. 4-7. Når ambolten 56 træder ind i bakken 54*s hulrum 57, bevæges ledningen til den i fig. 5 viste stilling, og en yderligere sammenklemning bevirker, at fingrene bøjer omkring og styrer ledningen på en sådan måde, at den bevæges nøjagtigt på tværs af sin længderetning ned til spalternes bund. Da filmen 6's indre overflade kun kommer i berøring med flade eller let afrundede overflader i ferrulen 4, vil filmen 6 ikke blive beskadiget, hvorved dens isolerende egenskaber bevares.An advantage of the connector described above is that the wire is precisely guided into the slots 20 and 23 and the bent fingers ensure that the cord is pressed against the bottom of the slots, thereby ensuring a good connection between the core 70 of the conduit 8 and the clamping metal ferrule 4. The manner in which the wire is centered relative to the connector is shown in FIG. 4-7. As the anvil 56 enters the cavity 57 of the tray 54 *, the conduit for the one shown in FIG. 5, and a further squeeze causes the fingers to bend around and guide the cord in such a way that it moves precisely across its longitudinal direction down to the bottom of the slots. Since the inner surface of the film 6 comes into contact only with flat or slightly rounded surfaces in the ferroller 4, the film 6 will not be damaged thereby preserving its insulating properties.
De ombøjede fingre vil i sammenklemt tilstand udgøre en stiv rørformet struktur, som beskytter tungerne.The bent fingers will, in the squeezed state, form a rigid tubular structure which protects the tongues.
Da parrene af fingre er delvist ombøjede, medens ledningen tvinges δ 149291 ned i spalterne, vil disse fingre, da de er anbragt på hver sin side af tungerne (se fig. 7 og 8), afstive tungerne mod at blive bøjet ud til siden ved indsættelse af ledningen. Grundpladen 12, sidevæggene 14 og de ombøjede fingre vil i den sammenklemte tilstand tilsammen danne en stiv opbygning.Since the pairs of fingers are partially bent while the cord is forced δ 149291 into the slots, these fingers, as they are disposed on either side of the tongues (see Figures 7 and 8), stiffen the tongues from being bent to the side by insertion of the cord. The base plate 12, the side walls 14 and the bent fingers will together form a rigid structure in the squeezed state.
Da fingrene ombøjes hen imod 360°, vil der i den sammenklemte tilstand optræde en smule relaksation, som på grund af fingrenes udformning bevirker, at ledningen trykkes yderligere ned mod spalternes bund. På denne måde udnyttes metallets iboende restelasticitet, idet metallet deformeres ud over elasticitetsgrænsen.As the fingers bend towards 360 °, in the squeezed state, some relaxation will occur which, due to the shape of the fingers, causes the cord to be pressed further down towards the bottom of the slots. In this way, the inherent residual elasticity of the metal is utilized as the metal deforms beyond the limit of elasticity.
Den nødvendige kraft til sammenklemning af forbindelsesorganet er mindre, end den ville være, hvis fingrene blev erstattet af et sammenhængende pladestykke.The force required to clamp the connector is less than it would be if the fingers were replaced by a continuous piece of plate.
Det er sandsynligt, at den nødvendige sammenklemningskraft er yderligere mindre, da ledningen ved sammenklemningen belastes fuldstændigt symmetrisk.It is likely that the required clamping force is even less since the clamping wire at the clamping is completely symmetrically loaded.
Filmen 6 kan erstattes med en korrugeret isoleret film, hvor kor-rugeringen er orienteret i forbindelsesorganets længderetning, som angivet i beskrivelsen til USA patent nr. 3.621.117. Anvendelse af en således korrugeret film vil være at foretrække, fordi korruge-ringen bevirker en låsende funktion mellem fingrenes modstående overflader, således at filmen fastholdes bedre til sammenklemningsferru-len. Den korrugerede film har også en bedre evne til at strække sig rundt om de ombøjede fingre under sammenklemningen.The film 6 can be replaced with a corrugated insulated film, the corrugation being oriented longitudinally of the connector, as disclosed in U.S. Patent No. 3,621,117. Use of such a corrugated film would be preferable because the corrugation causes a locking function between the opposing surfaces of the fingers so that the film is better adhered to the squeeze ferrule. The corrugated film also has a better ability to extend around the bent fingers during squeezing.
I fig. 12-15 er vist nogle udførelsesformer, hvor der er anvendt samme henvisningsnumre for dele, som tjener det samme formål som i de tidligere figurer.In FIG. Figures 12-15 show some embodiments where the same reference numbers are used for parts which serve the same purpose as in the previous figures.
I fig. 12 er vist et forbindelsesorgan, der er udformet på den samme måde som det tidligere beskrevne forbindelsesorgan, men hvor der sammenhængende mellem sammenklemningsferrulen er anbragt en flange 76 til en sammenboltningsforbindelse.In FIG. 12, there is shown a connecting member which is designed in the same manner as the previously described connecting member, but where a flange 76 is provided for a bolt-on connection between the clamping roller.
I fig. 13 er vist et lidt kortere forbindelsesorgan end det i fig.In FIG. 13 is shown a slightly shorter connector than that of FIG.
