Opfindelsen vedrører elektriske forbindelsesorganer for tilslutning til flade kabler og af den art, som er angivet i kravets indledning.This invention relates to electrical connection means for connection to flat cables and of the kind set forth in the preamble of the claim.
Det er almindeligt kendt at anvende elektriske forbindelsesorganer til flade kabler, hvor lederne trykkes ned i spalter i terminalerne, som gennemtrænger kablet på en sådan måde, at lederne bevæges ned i de respektive terminalers spalter. Se f.eks. USA patent nr. 3.189.863. Den i kravets indledning angivne udformning, hvor terminalarmenes frie ender samvirker med væggene i det andet hus' udsparinger, er f.eks. kendt fra engelsk patentskrift nr. 1.004.510.It is well known in the art to use electrical connectors for flat cables where the conductors are pushed into slots in the terminals which penetrate the cable in such a way that the conductors are moved down into the slots of the respective terminals. See, e.g. U.S. Patent No. 3,189,863. The design specified in the preamble of the claim, where the free ends of the terminal arms interact with the walls of the recesses of the second housing, are e.g. known from English Patent Specification No. 1,004,510.

Formålet med opfindelsen er at angive et i forhold til ovennævnte kendte teknik forbedret forbindelsesorgan, hvilket formål er opnået ved den i kravets kendetegnende del angivne udformning. Ved hagernes samvirkning med skuldrene opnås, at det andet hus er fikseret i den korrekte stilling, hvor den ledningsmodtagende del tilvejebringer en pålidelig elektrisk forbindelse med en leder i kablet. Specielt i forbindelse med et bredt fladkabel, hvor der er relativ stor afstand mellem koblingsorganer for sammenkobling af de nævnte huse, medfører opfindelsen en pålidelig forbindelse over hele kablets bredde, idet en ellers uundgåelig konveks udbøjning af det andet hus forhindres.The object of the invention is to provide an improved connection means in relation to the above-mentioned prior art, which object is achieved by the design according to the characterizing part of the claim. By the interaction of the gardens with the shoulders, it is achieved that the second housing is fixed in the correct position, where the conductor portion provides a reliable electrical connection with a conductor in the cable. Especially in connection with a wide flat cable, where there is a relatively large distance between coupling means for interconnecting said houses, the invention provides a reliable connection over the entire width of the cable, preventing an otherwise unavoidable convex bending of the second housing.
Opfindelsen vil blive nærmere forklaret ved den følgende beskrivelse af nogle udførelsesformer, idet der henvises til tegningen, hvor fig. 1 i perspektiv viser et forbindelsesorgan ifølge opfindelsen, hvor grundpladen er adskilt fra dækpladen, fig. 2 i perspektiv et forbindelsesorgan ifølge opfindelsen monteret på et fladt kabels ene ende, fig. 3 og 4 et tværsnit langs linierne 3-3 og 4-4 i fig. 2, fig. 5 en del af et fladt kabel af den type, til hvilket forbindelsesorganet ifølge opfindelsen er beregnet, fig. 6 et tværsnit langs linien 6-6 i fig. 5> fig. 7 et apparat til montering af forbindelsesorganets grundplade til et kabel, hvor kablets ledere tvinges ned i spalterne i forbindelse sorganets terminaler, fig. 8 et tværsnit langs linien 8-8 i fig. 7» som viser undersiden af kabelmonteringsbakken, fig. 9 et tværsnit, som viser en del af kabelmonteringsbakken og forbindelsesorganets grundflade, hvilken figur viser kabelledernes første bevægelse ind i terminalernes spalter, 3 147779 fig. 10 det samme som fig. 9, men hvor kabelmonteringsforløbet er tilendebragt, fig. 11 i perspektiv et kontaktelement ifølge opfindelsen, mens fig. 12 viser det i fig. 11 viste kontaktelement set bagfra.The invention will be explained in more detail by the following description of some embodiments, with reference to the drawing, in which fig. 1 is a perspective view of a connector according to the invention, wherein the base plate is separated from the cover plate; FIG. 2 is a perspective view of a connector according to the invention mounted on one end of a flat cable; FIG. 3 and 4 are a cross section along lines 3-3 and 4-4 of FIG. 2, FIG. 5 shows a portion of a flat cable of the type to which the connecting means according to the invention is intended; FIG. 6 is a cross-sectional view taken along line 6-6 of FIG. 5> FIG. 7 shows an apparatus for mounting the base plate of the connector to a cable where the conductors of the cable are forced into the slots in connection with the terminals of the organ, FIG. 8 is a sectional view taken along line 8-8 of FIG. 7, showing the underside of the cable mounting tray, FIG. Fig. 9 is a cross-sectional view showing a portion of the cable mounting tray and the base of the connecting member, which shows the first movement of the cable conductors into the slots of the terminals; 10 the same as FIG. 9, but where the cable mounting process is completed, FIG. 11 is a perspective view of a contact element according to the invention, while FIG. 12 shows that in FIG. 11 as seen from behind.
I fig. 5 og 6 er vist en meget anvendt form for et fladt kabel 4, som indeholder et antal parallelle ledere 2, som enten kan være massive eller snoede, og som er indeholdt i et sammenhængende plast profil 6. Kablets 8 underside har en overflade, som i ledernes længderetning har riller eller fordybninger 10 mellem lederne, og som i tværsnit udviser et antal bueformede forhøjninger ved siden af hinanden. Oversiden 11 er i det væsentlige flad, men kan have små riller 12 mellem hosliggende ledere i flugt med rillerne 10.In FIG. 5 and 6 are shown a widely used form of a flat cable 4 containing a plurality of parallel conductors 2 which can be either solid or twisted and contained in a continuous plastic profile 6. The underside of the cable 8 has a surface which in the longitudinal direction of the conductors have grooves or recesses 10 between the conductors and which in cross section show a number of arcuate elevations side by side. The upper side 11 is substantially flat but may have small grooves 12 between adjacent conductors in alignment with the grooves 10.
De i fig. 5 og 6 viste kabler fremstilles med et forskellig antal ledere af varierende sværhedsgrad. Ved en meget anvendt kabeltype er afstanden mellem lederne 1-2 mm, hvor lederne har benævnelsen AWG 28 eller 30.The 5 and 6 cables are manufactured with a different number of conductors of varying severity. In a widely used cable type, the distance between the conductors is 1-2 mm, where the conductors are designated AWG 28 or 30.
Det i fig. 1 og 2 viste forbindelsesorgan ifølge opfindelsen består af et første hus i form af en grundplade 18 og et andet hus i form af en dækplade 16, hvor grundpladen har et antal elektriske terminaler 20 anbragt i to parallelle rækker, som strækker sig langs grundpladens sider. Som vist i fig. 11 og 12 har hver terminal mellem dens ender et tværstykke 22, som består af to parallelle pladestykker 24, 26, som er indbyrdes forbundne ved hjælp af en lodret løbende bøjning 25. Pra pladedelen 26 strækker en tilslutningsdel 28 sig nedad, hvilken tilslutningsdel i nærheden af pladedelen har et udvidet område, i hvilket der findes en knop 30 til fastholdelse af terminalen i et hus, som senere beskrevet.The FIG. 1 and 2, the connector according to the invention consists of a first housing in the form of a base plate 18 and a second housing in the form of a cover plate 16, the base plate having a plurality of electrical terminals 20 arranged in two parallel rows extending along the sides of the base plate. As shown in FIG. 11 and 12, each terminal between its ends has a transverse piece 22, which consists of two parallel plate pieces 24, 26, which are interconnected by means of a vertical continuous bend 25. At the plate part 26, a connection part 28 extends downwards, which connection part in the vicinity of the plate part has an expanded area in which is provided a knob 30 for holding the terminal in a housing, as described later.
Fra pladedelen 26 strækker et par arme 32 sig opad med en indbyrdes afstand til dannelse af en første ledningsmodtagende spalte 36. De øvre dele af spaltens 36 modstående kanter divergerer således, at spaltens bredde tiltager opad i lodret retning. Armenes udadvendte kanter 38 konvergerer svagt i armenes midterområder og er udformet med relativt skarpt tilspidsede øvre ender, som vist ved 39. Armenes øvre eller frie ender er således udformet til let at kunne trænge 147779 4 gennem kablets isolation.From the plate portion 26, a pair of arms 32 extend upwardly with one another to form a first conduit receiving slot 36. The upper portions of the opposite edges of the gap 36 diverge so that the width of the gap increases upwards in a vertical direction. The outward edges of the arms 38 converge slightly in the middle regions of the arms and are formed with relatively sharply pointed upper ends, as shown at 39. Thus, the upper or free ends of the arms are designed to readily penetrate the cable's insulation.
Fra plad.ed.elen 24 strækker et lignende par arme 40 sig opad med divergerende modstående kanter 41, som definerer en anden ledningsmodtagende spalte 42. Armenes 40 udadvendte kanter 44 konvergerer også, som ovenfor nævnt, og de øvre eller frie ender 46 har fremspring, som rager ud til siden, således at der dannes nedadvendende hager 43.From the plate portion 24, a similar pair of arms 40 extend upwardly with divergent opposing edges 41 defining another conduit receiving slot 42. The outward edges 44 of the arms 40 also converge, as mentioned above, and the upper or free ends 46 have projections. which protrudes to the side so as to form downwardly facing hooks 43.
Armene 32,40 er således i det væsentlige ens bortset fra fremspringene på armene 40's øvre ender 46. Det skal også bemærkes, at armene 40 hælder skråt ind imod armene 32, som ligger i samme plan som pladedelen 36, således at armenes frie ender er tæt beliggende i forhold til hinanden af grunde, som senere vil blive forklaret.The arms 32, 40 are thus substantially the same except for the projections on the upper ends 46 of the arms 40. It should also be noted that the arms 40 incline inclined towards the arms 32 which lie in the same plane as the plate portion 36 so that the free ends of the arms are close to each other for reasons that will be explained later.

Den i fig. 11 viste terminal kan fremstilles i en hvilken som helst størrelse afhængig af ledernes størrelse. Til ledere med benævnelsen AWG 28 eller 30 vil det være passende med en terminal, der er fremstillet af en 0,25 mm tyk metalplade. Det er hensigtsmæssigt at fremstille terminalen af et metal med en god fjederkarakteristik, som f.eks. phosphorbronze, idet den samme terminal derved kan anvendes til større udvalg af ledningstykkelser. Som det senere vil blive forklaret, indebærer den måde, hvorpå forbindelsesorganet ifølge opfindelsen fastgøres til et kabel, og den konstruktive udformning af terminalen, at der kan anvendes et relativt tyndt plademateriale med en god fjederkarakteristik i stedet for en tykkere plade, som i hovedsagen er stærkere og mindre elastisk end den ovenfor nævnte phosphorbronze.The FIG. 11 can be made in any size depending on the size of the conductors. For conductors named AWG 28 or 30, a terminal made of a 0.25 mm thick metal plate would be appropriate. It is convenient to make the terminal of a metal with a good spring characteristic, such as e.g. phosphor bronze, thereby allowing the same terminal to be used for a greater variety of wire thicknesses. As will be explained later, the manner in which the connector according to the invention is attached to a cable and the constructive design of the terminal means that a relatively thin sheet material with a good spring characteristic can be used instead of a thicker plate, which is generally stronger and less elastic than the phosphor bronze mentioned above.
Grundpladen 18 består af et isolerende materiale med vulste 51 på undersiden til understøtning af forbindelsesorganet på et trykkredsløb. Terminalerne 20 er anbragt i to rækker udsparinger 52,52’, som strækker sig ind i grundpladen fra dennes øvre overflade 53. Udsparingerne 52 har en hylde eller et anlæg 54 under grundpladens øvre overflade, fra hvilket anlæg en relativt mindre åbning 56 strækker sig til grundpladens underside 58, hvor åbningen 56 er forskudt et stykke til siden i forhold til udsparingens øvre dele til optagelse af terminalernes forskudte tilslutningsdele 28. Som det bedst kan ses i fig. 4 modtager åbningerne 56 tilslutningsdelene 28’s udvidede 5 147779 øvre dele, hvor knoppen 30 findes, og tværstykket 22’s nedre kanter er lejret i hver af udsparingernes anlæg 54. udsparingerne 52· er udformet på samme måde som udsparingerne 52 blot med den forskel, at åbningerne..5b er anbragt til den modsatte side for de respektive udsparinger. På denne måde vil de ledningsmodtagne spalter i en række være anbragt med lige store indbyrdes afstande på 2,5 mm og forskudt et stykke 1,25 mm i forhold til de ledningsmodtagne spalter i den anden række, således at terminalerne vil kunne forbindes til kablets ledere, som vist ved krydser i fig. 5.The base plate 18 consists of an insulating material with bead 51 on the underside to support the connector on a pressure circuit. The terminals 20 are arranged in two rows of recesses 52,52 'which extend into the base plate from its upper surface 53. The recesses 52 have a shelf or abutment 54 below the upper surface of the base plate, from which abutment a relatively smaller opening 56 extends to the underside 58 of the base plate, the opening 56 being offset a bit laterally relative to the upper portions of the recess for receiving the displaced connection portions of the terminals 28. As best seen in FIG. 4, the openings 56 receive the extended portions 28 of the upper portions 28 of which the knob 30 is located, and the lower edges of the crosspiece 22 are housed in each of the recesses 54 of the recesses 52. .5b is positioned to the opposite side for the respective recesses. In this way, the cable-received slots will be arranged in a row with equal spacings of 2.5 mm and offset by a distance of 1.25 mm with respect to the cable-received slots in the second row, so that the terminals can be connected to the cable conductors. , as shown by crosses in FIG. 5th
I begge ender af grundpladen findes der låsearme 60,60’, som har udvidede frie ender 62. Disse låsearme er indrettet til at gå i indgreb med udskæringer 64,64’ i dækpladen, hvilke udskæringer har med låsearmenes udvidede ender 62 samvirkende, opadvendende skuldre. Låsearmenes øvre ender rager en smule op over de i grundpladen 18 anbragte terminaler 20, således at kablet 4 kan anbringes mellem låsearmene, før dette fastgøres til forbindelsesorganet.At both ends of the base plate there are locking arms 60,60 'which have extended free ends 62. These locking arms are arranged to engage cuts 64,64' in the cover plate, which cuts with the extended ends 62 cooperating, upwardly extending shoulders. . The upper ends of the locking arms extend slightly above the terminals 20 located in the base plate 18, so that the cable 4 can be placed between the locking arms before being attached to the connecting means.
Dækpladen 16 har to rækker åbninger 66, som strækker sig gennem pladen fra dennes overside 65 til undersiden 68, hvilke åbninger er indrettet til at kunne modtage terminalernes arme 32,40. Som det bedst kan ses i fig. 4 har hver åbning en konisk del 70 tæt ved dækpladens underside, og har en mellemliggende cylindrisk del 73 i fortsættelse af den koniske del, samt har en udvidet øvre del, hvis indre ende definerer en opadvendende skulder 72. Den relativt ! korte cylindriske del 73's diameter er med fordel en smule mindre end afstanden tværs over armene 40’s modsat rettede kanter ved hagerne 43, således at armene vil blive bøjet en smule sammen af dækpladen.Cover plate 16 has two rows of openings 66 which extend through the plate from its upper side 65 to the underside 68, which openings are arranged to receive the arms 32.40 of the terminals. As best seen in FIG. 4, each opening has a conical portion 70 close to the underside of the cover plate, and has an intermediate cylindrical portion 73 in continuation of the conical portion, and has an extended upper portion, the inner end of which defines an upwardly extending shoulder 72. The relative! The diameter of the short cylindrical portion 73 is advantageously a little less than the distance across the opposite sides of the arms 40 at the hooks 43, so that the arms will be slightly bent by the cover plate.
Dækpladen er med fordel forsynet med en lav rektangulær udsparing 67, som vist i fig. 1. Når grundpladen og dækpladen fastgøres til kablet, vil dette blive fastholdt mellem modstående overflader i grundpladen og dækpladen, som afgrænser udsparingen 67, og kablets plastmateriale vil fordele sig på den i fig. 3 viste måde. Udsparingen 67 tillader således, at kablet fastholdes nænsomt mellem grundpladen og dækpladen.The cover plate is advantageously provided with a low rectangular recess 67, as shown in FIG. 1. When the base plate and the cover plate are attached to the cable, this will be held between opposite surfaces of the base plate and the cover plate defining the recess 67, and the plastic material of the cable will be distributed on the one shown in FIG. 3. Thus, the recess 67 allows the cable to be gently held between the base plate and the cover plate.

Forbindelsesorganet fastgøres med fordel til kablet ved hjælp af det i fig. 7 viste apparat, som omfatter en skabelon 76, der fastholdes mellem hagekilder 78 på en grundplade 80, der igen kan være fastgjort til et arbejdsbord. Skabelonen 76 er aftagelig fra grundpladen, således at der kan anbringes forskellige skabeloner svarende til de anvendte forbindelsesorganer. Til optagelse af terminalernes tilslutningsdele 28 i en grundpladesektion 18 har skabelonen to rækker relativt små cirkulære åbninger 82 og har to relativt store åbninger 84 til modtagelse af vulstene 51 på grundpladens underside. På skabelonen findes også to 1 c de s t Gonger 86 til styring af kablet i forhold til det forbindelsesorgans grundplade, som er anbragt på skabelonen. Kablet styres også ved hjælp af en stopklods 88, der har en overflade 90, som ved montering af kablet berører dettes ende. Stopklodsen 88 er anbragt justerbart, som vist ved 92 til en opspændingsblok 94, der er fastgjort til grundpladen.Advantageously, the connecting means is attached to the cable by means of the connection shown in FIG. 7, which comprises a template 76 which is held between garden springs 78 on a base plate 80 which may in turn be attached to a work table. The template 76 is removable from the base plate, so that different templates corresponding to the connecting means used can be placed. To accommodate the terminals 28 of the terminals in a base plate section 18, the template has two rows of relatively small circular openings 82 and has two relatively large openings 84 for receiving the beads 51 on the underside of the base plate. Also provided on the template are two 1 c de s t Gongs 86 for controlling the cable relative to the base plate of the connector located on the template. The cable is also guided by a stop block 88 having a surface 90 which, when mounting the cable, touches its end. The stop block 88 is adjustably positioned, as shown at 92 to a clamping block 94 attached to the base plate.
Kablet presses nedad på grundplade delen ved hjælp af en bakke eller presseblok 96, som er anbragt for enden af et pressestempel 98. Det vil forstås, at blokken 96 og grundpladen 80 kan anvendes i forbin-cfelss med en hvilken som helst egnet bænkpresse. Blokken 96 består af tre sektioner 100, 100* og 102, som vist i fig. 8. Sektionerne 100, 100r har på siden udskæringer 108, som vender mod raidtersek-tionen 102, hvorved der frembringes rektangulære åbninger, som strækker sig ind i blokken fra neden. Udskæringerne har skråkanter som vist ved 105 til styring af terminalernes kanter ved kablets montering. Udskæringernes 108 bredde er i det væsentlige lig med eller en smule større end afstanden mellem yderkanterne for armene 40’s fremspring 46 (fig. 9). Begge par af arme kan således bevæges frit i udskæringerne, som vist i fig. 9, men armene fastholdes mod udbøjning, mens ledningerne bevæges ned i spalterne. Det skal også anføres, at åbningerne 108, 108’ har en lidt større bredde end afstanden mellem armene 52,40's overflader, som vender bort fra hinanden, men er ikke meget større af hensyn til afstøtning mod udbøjning af armene.The cable is pressed downwardly on the base plate portion by means of a tray or press block 96 disposed at the end of a press plunger 98. It will be appreciated that block 96 and base plate 80 can be used in connection with any suitable bench press. The block 96 consists of three sections 100, 100 * and 102, as shown in FIG. 8. The sections 100, 100r on the side have cut-outs 108 which face the raider section 102, thereby producing rectangular openings extending into the block from below. The cutouts have bevelled edges as shown at 105 for controlling the edges of the terminals when installing the cable. The width of the cutouts 108 is substantially equal to or slightly greater than the distance between the outer edges of the projections 46 of the arms 40 (Fig. 9). Thus, both pairs of arms can be moved freely in the cuts, as shown in FIG. 9, but the arms are held against deflection while the wires are moved down the slots. It should also be noted that the openings 108, 108 'have a slightly wider width than the distance between the surfaces of the arms 52,40 which are facing away from each other, but are not much larger for the purpose of supporting the bending of the arms.
Sektionerne 100,100», 102 fastholdes i forhold til hinanden ved hjælp af passende spændeanordninger. I presseblokkens underside 7 147779 findes der åbninger 104 til låsearmene 60,60’ på grundpladedelen 18, og endvidere findes der en udsparing 106 til stopklodsen 88.Sections 100,100 », 102 are held relative to each other by suitable clamping means. On the underside of the press block 7 147779 there are openings 104 for the locking arms 60,60 'on the base plate portion 18, and further there is a recess 106 for the stop block 88.
Når der skal fastgøres et forbindelsesorgan 14 til et kabel 4 anbringes først grundpladen 18 på skabelonen 76 med tilslutningsdelene 28 i hullerne 82. Kablets ende anbringes derefter mellem stængerne 86 med den afskårne ende mod overfladen 90. Derefter aktiveres pressen, således at bakken 96 bevæges nedad, som vist i fig. 9, til den i fig. 10 viste stilling. Derved vil de øvre ender for hver terminals arme gennemtrænge kablet til hver side for lederne 2 og strække sig ind i åbningerne 108 i bakken. Ved bakkens fortsatte nedadgående bevægelse tvinges lederne ind i spalterne 36,42's indre ender og helt ned i den snævre del, som strækker sig ind i terminalens tværstykke 22.When attaching a connector 14 to a cable 4, the base plate 18 is first placed on the template 76 with the connecting members 28 in the holes 82. The cable end is then placed between the rods 86 with the cut end against the surface 90. Thereafter, the press is actuated so that the tray 96 moves downwardly , as shown in FIG. 9, to the one shown in FIG. 10. Thereby, the upper ends of the arms of each terminal will penetrate the cable to each side of the conductors 2 and extend into the openings 108 in the tray. As the downward movement continues downward, the conductors are forced into the inner ends of the slots 36, 42 and all the way down into the narrow portion which extends into the cross section 22 of the terminal.
Som tidligere nævnt kan terminalen med fordel fremstilles af relativt tyndt materiale med en god fjederkarakteristik, således at armene vil blive bøjet ud til siden, mens lederne smedes ned i spalterne, som vist i fig. 10. Armenes øvre ender bøjes imidlertid ikke ud, da disse støttes af åbningerne 108's vægge. Med andre ord ville de ved indsættelse af kablet frembragte kræfter frembringe en større udbøjning af armene end den i fig. 10 viste, hvis disses bevægelse ikke var begrænset af åbningerne 108’s vægge. Som følge af at armene støttes ved kablets indsættelse, vil dettes individuelle ledere deforneres kraftigere end ellers, hvorved der tilvejebringes en ren overflade og god elektrisk kontakt mellem lederne og spalternes kanter. Da lederne er af kobber, der er blevet deformeret blivende ved montering af kablet, vil terminalernes arme ikke blive bøjet ud, når blokken 96 fjernes.As previously mentioned, the terminal can advantageously be made of relatively thin material with a good spring characteristic, so that the arms will be bent to the side while the conductors are forged into the slots, as shown in FIG. 10. However, the upper ends of the arms are not bent as they are supported by the walls of the openings 108. In other words, the forces produced by inserting the cable would produce a greater deflection of the arms than that of FIG. 10 showed if their movement was not restricted by the walls of the openings 108. As the arms are supported by the insertion of the cable, its individual conductors will be more heavily deflected than otherwise, thereby providing a clean surface and good electrical contact between the conductors and the edges of the slots. As the conductors are of copper that has been deformed permanently by the cable assembly, the arms of the terminals will not be extended when the block 96 is removed.
Blokken 96's formål er også at forhindre udbøjning eller anden fejlfunktion af terminalerne ved indsættelse af kablet som følge af opståede tryk- eller torsionsspændinger. Terminalerne behøver derfor ikke ax være fremstillet af et tykt materiale for at kunne modstå sådanne spændinger. Den støtte, der opnås ved åbningerne i blokken 96, tillader således, at der kan anvendes et relativt tyndt materiale med en god fjederkarakteristik, som tidligere nævnt.The purpose of block 96 is also to prevent deflection or other malfunction of the terminals by insertion of the cable due to pressure or torsional stresses. Therefore, the terminals need not be made of a thick material to withstand such stresses. Thus, the support obtained at the openings in block 96 permits the use of a relatively thin material with a good spring characteristic, as previously mentioned.
8 147779 Når kablets ledere er Indsat i terminalernes spalter, trækkes blokken 96 tilbage, og kablets ende undersøges for eventuelle mangler eller fejl. På dette trin vil en overfladisk -betragtning af de elektriske forbindelser afsløre en hvilken som helst fejl, som f.eks. forkert placerede ledere eller utilstrækkeligt indsatte ledere. Selv om sådanne fejl kun sjældent optræder og sædvanligvis er et resultat af forkert betjening af apparatet, vil de alligevel optræde med en hvis hyppighed, således at det er en fordel at kunne kontrollere forbindelsen på dette tidspunkt.8 147779 When the cable conductors are inserted into the terminals of the terminals, the block 96 is retracted and the cable end is examined for any defects or faults. At this stage, a superficial consideration of the electrical connections will reveal any failure, such as incorrectly positioned managers or inadequately deployed managers. Although such errors rarely occur and are usually the result of improper operation of the apparatus, they will nevertheless occur at a frequency of one, so that it is advantageous to be able to check the connection at this time.
Derefter fastgøres dækpladen 16 til grundpladen 18 ved blot at trykke den ned, indtil låsearmene er lejret i udskæringerne 64.Then, the cover plate 16 is secured to the base plate 18 by simply pushing it down until the locking arms are mounted in the cutouts 64.
Armene 32,40's øvre ender vil blive bøjet indad ved montering af dækpladen, og når fremspringene 46 passerer den cylindriske del 73, vil armene delvist vende tilbage til deres normale stilling, og hagerne 43 vil blive lejret mod overfladen 72, som vist i fig. 4.The upper ends of the arms 32.40 will be bent inwardly by mounting the cover plate, and as the projections 46 pass the cylindrical portion 73, the arms will partially return to their normal position and the hooks 43 will be positioned against the surface 72, as shown in FIG. 4th
Som tidligere nævnt har hver åbning 66’s cylindriske del 73 en sådan diameter, at armene bøjes en smule indad af dækpladen.As previously mentioned, each opening 66's cylindrical portion 73 has a diameter such that the arms are slightly bent inward by the cover plate.
Adskillige fordele ved forbindelsesorganet er en følge af, at terminalerne kan fremstilles af et relativt tyndt plademateriale med en god fjederkarakteristik. Når et forbindelsesorgan er fastgjort til et kabel, vil de derved frembragte fjederspændinger på fjedrende måde klemme spalternes kanter mod ledningen. Årsagen til at der kan anvendes et tyndt materiale, som ovenfor nævnt, er, at terminalernes arme støttes mod udbøjning ved indsættelse af kablet. Ved at anvende to sæt kontaktarme opnås en tilstrækkelig kontaktoverflade til trods for det tynde metal.Several advantages of the connector are the result that the terminals can be made of a relatively thin sheet material with a good spring characteristic. When a connecting means is attached to a cable, the spring voltages thus produced will resiliently clamp the edges of the slots against the wire. The reason for using a thin material, as mentioned above, is that the arms of the terminals are supported against deflection by inserting the cable. By using two sets of contact arms, a sufficient contact surface is obtained despite the thin metal.
En anden fordel ved forbindelsesorganet er, at der tilvejebringes fire adskilte kontaktområder mellem hver terminal og hver leder, hvorved der opnås større sikkerhed mod dårlige forbindelser. Det er også en fordel, at de enkelte kontaktarme holdes i en spændt tilstand af dækpladen og griber således ind i dækpladen, at denne holdes fast mod kablets øvre overflade. Når hver kontaktarm således hjælper til at holde dækpladen mod kablets overside, vil dækpladen ikke kunne løsne sig og bevirke dårligere elektriske 9 147779 forbindelser.Another advantage of the connector is that four separate contact areas are provided between each terminal and each conductor, thereby providing greater security against poor connections. It is also an advantage that the individual contact arms are held in a tensioned state by the cover plate and engage in the cover plate so that it is held firmly against the upper surface of the cable. Thus, as each contact arm helps to hold the cover plate against the top of the cable, the cover plate will not be able to loosen and cause poor electrical connections.
Som tidligere beskrevet hælder terminalen 20*s arme 40 skråt ind imod armene 32. Denne ringe hældning er fordelagtig, fordi de modstående kanter på armene 40’s spalte derved vil ligge tæt op til de modstående kanter på armene 32’s spalte, navnlig ved armenes yderste ender. Når lederen ^vinges nedad, som vist i fig. 9, vil kablets plastisolation blive trukket væk fra lederen, idet et aftrukket stykke isolation uden ulempe kan ligge mellem armene 40 og 32’s modstående overflader. Mellemrummet mellem disse overflader er mindst ved armenes øvre ender og bliver større ved armenes nedre ender (tæt ved tværstykket 22). Når lederen trykkes ned i spalterne, vil plastisolationen strække sig, men det forøgede mellemrum mellem armene 40 og 32’s modstående overflader kan optage det extruderede plast, således at dette ikke i stedet smedes ned i kontaktområdet mellem lederen og kontaktarmene.As previously described, the terminal 20 * arms 40 incline obliquely against the arms 32. This slight inclination is advantageous because the opposite edges of the slots of the arms 40 will thereby be close to the opposite edges of the slots of the arms 32, especially at the outer ends of the arms. When the conductor is turned downwards, as shown in FIG. 9, the plastic insulation of the cable will be pulled away from the conductor, as a pulled insulation without inconvenience may lie between the opposing surfaces of the arms 40 and 32. The space between these surfaces is at least at the upper ends of the arms and becomes larger at the lower ends of the arms (close to the cross piece 22). When the conductor is pressed into the slots, the plastic insulation will extend, but the increased space between the opposing surfaces of the arms 40 and 32 can absorb the extruded plastic so that it does not forge into the contact area between the conductor and the contact arms instead.
Terminalerne ifølge opfindelsen fremstilles ud fra et stykke metalplade, som bøjes langs bøjningen 25, således at armene 32,40 i det væsentlige flugter med hinanden. Det er hensigtsmæssigt, hvis armene ikke flugter helt nøjagtigt, således at de respektive spalter er forskudt et lille stykke i forhold til hinanden. Derved fremkaldes der trækspændinger i lederen, fordi denne strækkes, hvilke trækspændinger yderligere bidrager med en fjedervirkning til frembringelse af en stabil elektrisk forbindelse mellem lederen og kontaktarmene.The terminals of the invention are made from a piece of metal plate which is bent along the bend 25 so that the arms 32, 40 are substantially flush with each other. It is advisable if the arms do not align exactly so that the respective slots are offset slightly to each other. This causes tension in the conductor because it is stretched, which further contributes to a spring effect to produce a stable electrical connection between the conductor and the contact arms.
Det har tidligere været angivet, at kablets underside (se fig. 6) er abragt mod kontaktarmenes øvre ender. Det bemærkes, at begge sider af kablet kan anbringes mod terminalernes øvre ender, hvor rillerne 12 i det viste kabel tjener til at styre dette i forhold til terminalerne. Visse kabler har ikke sådanne riller og må derfor styres udelukkende ved hjælp af låsearmene 60,60* eller ved hjælp af stænger 86 på monteringsværktøjet.It has previously been stated that the underside of the cable (see Fig. 6) is projected towards the upper ends of the contact arms. It is noted that both sides of the cable may be positioned against the upper ends of the terminals, where the grooves 12 of the shown cable serve to control this relative to the terminals. Certain cables do not have such grooves and must therefore be controlled solely by means of the locking arms 60,60 * or by means of rods 86 on the mounting tool.
Det i figurerne viste forbindelsesorgan kan monteres på et trykt kredsløb, idet tilsutningsdelene 28 loddes til lederne på kredsløbets underside, eller indsættes i dertil egnede sokler. EfterThe connecting means shown in the figures can be mounted on a printed circuit, the connection parts 28 being soldered to the conductors on the underside of the circuit, or inserted into suitable plinths.
